High blood pressure and sex: Overcome the challenges
You can be treated for high blood pressure and still enjoy a satisfying sex life — if you discuss any problems and work closely with your doctor.
By Mayo Clinic Staff
A link between high blood pressure and sexual problems has been proved in men. For women who have decreased sexual satisfaction, it's not yet been proved that high blood pressure is to blame.
Challenges for men
Over time, high blood pressure damages the lining of the blood vessels and causes arteries to harden and narrow (atherosclerosis), limiting blood flow. This means that less blood flows to the penis.
For some men, the decreased blood flow makes it difficult to achieve and maintain erections. This problem is called erectile dysfunction. It's fairly common.
Even a single episode of erectile dysfunction can cause anxiety. Fears that it will happen again might lead men to avoid sex, which can affect the relationship with their sexual partners.
High blood pressure can also interfere with ejaculation and reduce sexual desire. Some blood pressure medications may cause similar effects.
Men should discuss any concerns with their doctors.
Challenges for women
High blood pressure's effect on sexual problems in women isn't well understood. But it's possible that high blood pressure could affect women's sex lives.
High blood pressure can reduce blood flow to the vagina and may lower levels of nitric oxide, a chemical that helps smooth muscles relax. In some women, this may cause:
 - Lowered sex drive or arousal
 - Difficulty achieving orgasm
 - Vaginal dryness
Using lubrication and learning ways to improve arousal can help.
Like men, women can have anxiety and relationship issues due to sexual dysfunction. Women should talk to their doctors if they are having any problems or concerns.
Sexual side effects of high blood pressure medications
Some high blood pressure medications may affect sex drive or sexual function.
Taking medications exactly as prescribed can help lower the risk of side effects, including sexual problems. If that doesn't work, talk to your doctor about other possible medications that may have fewer side effects.
Medications less likely to cause sexual side effects
If you are taking blood pressure medication and having sexual side effects, talk to your doctor about your options. Some high blood pressure medications are less likely to cause problems with sex drive and sexual function. For example, switching to a newer type of beta blocker improves symptoms in some men and women.
If your doctor says it's OK, you may be able to stop taking blood pressure medications for a short while to see if any sexual symptoms improve. During this time, you may need to frequently take blood pressure readings at home to make sure your blood pressure remains in a safe range.
Be sure to tell your doctor about every medication you take, including herbal supplements and all over-the-counter drugs. Sometimes supplements or a particular combination of medications or supplements can lead to sexual problems.
Erectile dysfunction drugs and high blood pressure
Men considering medications for erectile dysfunction should check with their doctors first. Erectile dysfunction drugs include sildenafil (Viagra), vardenafil (Levitra, Staxyn) and tadalafil (Cialis). The pill forms are generally considered safe for men with high blood pressure who are in otherwise good health.
Erectile dysfunction drugs aren't recommended for men with severe cardiovascular disease or for men with high blood pressure who have difficulties with urination or have other lower urinary tract problems. Never take erectile dysfunction drugs with nitrates, which are used to treat chest pain. Doing so can cause a dangerous drop in blood pressure.
Be honest with your doctor
Living with high blood pressure doesn't usually mean giving up a satisfying sex life. Talking openly and honestly with your doctor can help better manage your treatment and help you overcome any sexual challenges. Be prepared to answer questions your doctor may ask, such as:
 - What medications do you take?
 - Has your relationship with your sexual partner changed recently?
 - Are you sad or depressed?
 - Have you been under a lot of stress lately?
Promote overall health
Living a healthy lifestyle can lower your blood pressure and potentially improve your sex life. Try these healthy-lifestyle choices:
 - Do not smoke or use tobacco.
 - Eat healthy foods.
 - Limit the amount of alcohol you drink.
 - Reduce the amount of salt in your diet.
 - Get regular exercise.
 - Lose extra pounds.
A healthy and fit body can boost your confidence and help you feel more attractive, which could also improve your sex life.
Set the stage for satisfying sex
How you feel about your partner and where you have sex may affect your sexual response. To encourage satisfying sex, initiate sex when you and your partner are feeling relaxed. Explore various ways to be physically intimate, such as massage or warm soaks in the tub.
Share with each other the types of sexual activity you enjoy most. You may find that open communication is the best way to achieve sexual satisfaction. And studies have shown that a healthy, pleasurable sex life is good for the heart.

Katumani Research Center
About the Institute
The Agricultural Mechanization Research Institute (AMRI) is one of the 16 research institutes under the Kenya Agricultural and Livestock Research Organization (KALRO) that was established in November 2015.
Despite the importance of Agriculture in Kenya there is generally low levels of mechanization both in livestock and crop production. In Kenya 50 % of the land preparation depends on human power, 20 % on animal draught power and 30 % on machines. This has been associated with low productivity and high cost of production which inevitably leads to low profitability in major agricultural enterprises. The main function of AMRI is to generate and disseminate agricultural mechanization technologies /innovations across livestock and crops value chains in Kenya.
To achieve its mandate AMRI works closely with other KALRO research institutes handling different value chains, Ministry of Agriculture, Livestock and Fisheries (MoALF) through Agricultural Technology Development Centers (ATDCs) and the Agricultural Mechanization Services (AMS). Other institutions that collaborate with AMRI include Kenya Industrial Research and Development Research Institute (KIRDI), universities such as Jomo Kenyatta University of Agriculture and Technology (JKUAT) and University of Nairobi and Non-Governmental Organizations (NGOs) and development partners.
The Agricultural Mechanization Research Institute is located at Katumani in Machakos County (1º 35'S and 37º 14'E), 80 km southeast of Nairobi, and 9 km south of Machakos town, along the Machakos – Wote Road at an altitude of 1600 m above sea level.
The Institute has the national mandate to carry out research in agricultural mechanization along the livestock and crops value chains for increased productivity, commercialization and competitiveness of the agricultural sector through the following objectives to:
1. Identify research priority areas on agricultural mechanization in collaboration with the county governments and other stakeholders;
2. Undertake research on mechanized soil and water conservation and management;
3. Seek research and innovation advances in mechanized agriculture for improved productivity;
4. Promote international cooperation in agricultural mechanization research and information;
5. Promote linkages between research, extension and farmers for effective adoption of technological packages;
6. Develop user manuals, publications and materials on agricultural mechanization for dissemination; and
7. Promote coordinated and regulated research and technology development for agricultural mechanization sub-sector to gain from emerging knowledge.

If you don't supply an explicit list of files (or instructions on how to
generate one), the
sdist command puts a minimal default set
into the source distribution:
Sometimes this is enough, but usually you will want to specify
additional files to distribute. The typical way to do this is to write
a manifest template, called MANIFEST.in by default. The
manifest template is just a list of instructions for how to generate
your manifest file, MANIFEST, which is the exact list of files to
include in your source distribution. The
processes this template and generates a manifest based on its
instructions and what it finds in the filesystem.
If you prefer to roll your own manifest file, the format is simple: one filename per line, regular files (or symlinks to them) only. If you do supply your own MANIFEST, you must specify everything: the default set of files described above does not apply in this case.
The manifest template has one command per line, where each command specifies a set of files to include or exclude from the source distribution. For an example, again we turn to the Distutils' own manifest template:
include *.txt recursive-include examples *.txt *.py prune examples/sample?/build
The meanings should be fairly clear: include all files in the distribution root matching *.txt, all files anywhere under the examples directory matching *.txt or *.py, and exclude all directories matching examples/sample?/build. All of this is done after the standard include set, so you can exclude files from the standard set with explicit instructions in the manifest template. (Or, you can use the --no-defaults option to disable the standard set entirely.) There are several other commands available in the manifest template mini-language; see section 9.2.
The order of commands in the manifest template matters: initially, we have the list of default files as described above, and each command in the template adds to or removes from that list of files. Once we have fully processed the manifest template, we remove files that should not be included in the source distribution:
You can disable the default set of included files with the --no-defaults option, and you can disable the standard exclude set with --no-prune.
Following the Distutils' own manifest template, let's trace how the
sdist command builds the list of files to include in the
Distutils source distribution:
prunecommand in the manifest template comes after the

Hello everyone! Sarah Martin here to liveblog Saturday afternoon's Special Panel in the Blackfriars Playhouse. Today, we will hear two presentations: Tiffany Stern from the University of Oxford's Why Der Berstraffe Brudermord Might Be a Puppet Play (you can see Der Berstraffe Brudermord performed as a puppet play courtesy of Beth Burns and the Hidden Room theatre this evening at 9:30pm in the Blackfriars Playhouse) and The Complete Works presented by Paul Menzer from Mary Baldwin College, Jeremy Lopez from the University of Toronto, Andrea Stevens from the University of Illinois at Urbana-Champaign, and Genevieve Love from Colorado College.
Tiffany Stern, Oxford University
"Why Der Berstraffe Brudermord Might be a Puppet Play"
Stern begins her presentation with a brief explanation of Der Berstraffe Brudermord saying that it is an "eighteenth-century play of extraordinary awfulness". She says that Der Berstraffe Brudermord is probably not a puppet play, but that this possibility is certainly there. Stern's interest in the play began with research about puppet plays and the discovery of a puppet Hamlet. She explains that the text of the Der Berstraffe Brudermord is very close to the Quarto 1 Hamlet. This informs us that Q1 Hamlet must have been circulating in Germany at some point before Der Berstraffe Brudermord was written. Stern notes that the first mention of the possible puppet Hamlet was in 1779. She explains that Germany experienced a period of fascination with Shakespeare's works during the eighteenth century. She gives a brief history of English players in Germany. She explains that the same English players also performed in the Czech Rebublic. A Czech account of the English players' performances states that the actors, "alternately performed an actors' and a marionette repertoire". Stern gives an example of an Italian puppet Hamlet called Amleto from the 1660s that informs us that Shakespeare's plays were circulating on the continent before the plays were available in good translations.
As evidence for why Der Berstraffe Brudermord might be a puppet play, Stern notes that the Prologue requires four women, but the play only has two women characters. When the character of NIGHT enters, she does so in "flying machinery"–much easier for a puppet to accomplish rather than a person, obviously. The play also includes a lot of violent moments that occur from behind. All action in puppet shows takes place from behind and this contributes to why Der Berstraffe Brudermord might be a puppet play. Stern notes that Der Berstraffe Brudermord has several moments of fireworks–another hallmark of puppet shows. She points to the "Closet Scene" moment when the Hamlet character sees the ghost of his father and fireworks go off. Including fireworks at this moments seems odd and contributes to the "absurdity" one expects in puppet shows.
Sterns contacted Beth Burns about the possibility of the puppet show performance and Burns jumped on the idea. Stern says that she was nervous about the actual performance, and said "what if I'm wrong, oh but what if I'm not" and that led to tonight's production.
Paul Menzer, Mary Baldwin College; Jeremy Lopez, University of Toronto; Andrea Stevens, University of Illinois Urbana-Champaign; and Genevieve Love, Colorado College
The Complete Works
Paul Menzer begins his presentation by having the Mary Baldwin College MFA students pass out sheets of paper that contains lists of words all beginning with the same two letters (I have "ex" words). He then asks the audience to read aloud all of the many words on their pages as he does the same. As the reading comes to a close, Menzer notes that the ASC will produce Timon of Athens this Spring and will at that point, have performed all of Shakespeare's words. He then points out that we have done just that in a matter of a few minutes. The papers contained all of the words found in Shakespeare's works. Menzer points out that our performance, in claiming to have performed The Complete Works of Shakespeare, represents a "scaling fallacy". He notes that the "Complete Works" idea has the problem of scale. He explains that Shakespeare's Complete Works is large in comparison to Marlowe, but not compared to that of Thomas Heywood. Menzer then goes on to note that "Shakespeare's Complete Works is not bigger than Marlowe's, there's just more of it". He points out the problematic idea of "Complete Works" is that it implies a finishing point. He explains that scale is a measure not just of size, but of form as the agent doing the measuring is part of it. We, as those agents, contribute to Shakespeare's Complete Works–and contribute to what that term means exactly.
Jeremy Lopez begins by telling the audience that the word "disappointed" occurs only once in all of Shakespeare's works. Lopez gives several examples of word counts throughout works of great literature. Lopez argues of such "word counting" exercises are only applied to iconic authors and plays. He argues that we only decide to look for the instances of the word "blood" in Macbeth, for example, because we already know the play. Giving examples of several such instances of repeated words in plays that do not really have anything to do with those words, Lopez argues that repetition does not equal emphasis or meaning. He notes that though his paper, "is about disappointment, the word "disappointed" appears only once."
Andrea Stevens begins her presentation with an explanation of the use of the term "invulnerable" in Shakespeare's plays. She explains that it is the "vulnerable" bodies that are the victims of violence. Quoting Judith Butler, Stevens notes that our bodies are never exclusively our own. Our bodies also always have political value. She argues that Shakespeare's tragedies are explorations of how characters discover that they are, in fact, vulnerable and that their bodies are not their own.
Genevieve Love begins with a discussion of the "vulnerable". She talks about how characters with missing limbs and other physical disabilities give important bibliographical and textual history as well. Prosthetic bodies, Love argues, represent the incomplete articulation of the plays themselves. She points to Dr. Faustus–a play with both "A" and "B" texts as an example of how the disability of the body also represents the disability and deformity of corrupt texts. She argues that the dismemberment and multiplication of one, whole body into diverse incomplete parts is a reflection of the corruption and mutilation of early modern texts.


Concurrent Input-Output for improved performance. As mentioned earlier, you should still place Oracle Database logs on a separate JFS2 file system for optimal performance.

 4. Rename the data file.
Moving from Raw Logical Volumes to a Journaled File System
A.2.3 Using Asynchronous Input-Output
Oracle Database takes full advantage of asynchronous Input-Output provided by AIX, resulting in faster database access.
IBM AIX on POWER Systems support asynchronous Input-Output for database files created on file system partitions. When using asynchronous Input-Output on file systems, the kernel database processes (aioserver) control each request from the time a request is taken off the queue to the time it is completed. The number of aioserver servers determines the number of asynchronous Input-Output requests that can be processed in the system concurrently. So, it is important to tune the number of aioserver processes when using file systems to store Oracle Database data files.
Use one of the following commands to set the number of servers. This applies only when using asynchronous Input-Output on file systems:
 - smit aio
 See Also:
 - On IBM AIX on POWER Systems, there are two asynchronous Input-Output subsystems available. Oracle Database 11g uses Legacy asynchronous Input-Output (aio0), even though the Oracle preinstallation script enables Legacy asynchronous Input-Output (aio0) and POSIX AIO (posix_aio0). Both asynchronous Input-Output subsystems have the same performance characteristics.
 - Starting with AIX 6.1, the minservers, maxservers, and maxreqs parameters are replaced by the aio_minservers, aio_maxservers, and aio_maxreqs parameters respectively.
The default value for the minimum number of servers is 1. The default value for the maximum number of servers is 10. These values are usually too low to run Oracle Database on large systems with 4 CPUs or more, if you are not using kernelized asynchronous Input-Output. Oracle recommends that you set the parameters to the values listed in the following table:
Parameter Value
maxservers Starting with AIX 5L version 5.3, this parameter counts the maximum number of asynchronous Input-Output servers for each CPU. On previous versions of AIX, it was a systemwide value. If you are using General Parallel File System (GPFS), then set maxservers to worker1threads divided by the number of CPUs. This is the optimal setting. Increasing maxservers does not lead to improved Input-Output performance.
If you are using JFS/JFS2, then set the initial value to 10 times the number of logical disks divided by the number of CPUs that are to be used concurrently but no more than 80. Monitor the actual number of aioservers started during a typical workload using the pstat or ps commands. If the actual number of active aioservers equals the maxservers, then increase the maxservers value.
$ lsattr -E -l hdiskxx
Typically, the queue depth is 3.
Warning: lio_listio returned EAGAINPerformance degradation may be seen.
You can avoid these errors by increasing the value of the maxservers parameter. To display the number of asynchronous Input-Output servers running, enter the following commands as the root user:
# pstat -a | grep -c aios
# ps -k | grep aioserver
Check the number of active asynchronous Input-Output servers periodically, and change the values of the minservers and maxservers parameters if required. The changes take place when the system is restarted.
See your operating system vendor documentation for information about tuning AIO parameters.
A.2.4 Input-Output Slaves
Input-Output Slaves are specialized Oracle processes that perform only Input-Output. They are rarely used on AIX, because asynchronous Input-Output is the default and recommended way for Oracle to perform Input-Output operations on AIX. Input-Output Slaves are allocated from shared memory buffers. Input-Output Slaves use the initialization parameters listed in the following table:
Parameter Range of Values Default Value
DISK_ASYNCH_IO true/false true
TAPE_ASYNCH_IO true/false true
BACKUP_TAPE_IO_SLAVES true/false false
DBWR_IO_SLAVES 0 - 999 0
There are times when you must turn off asynchronous I/O. For example, if instructed to do so by Oracle Support for debugging. You can use the DISK_ASYNCH_IO and TAPE_ASYNCH_IO parameters to switch off asynchronous I/O for disk or tape devices. TAPE_ASYNCH_IO support is only available when the Media Manager software supports it and for Recovery Manager, if BACKUP_TAPE_IO_SLAVES is true.
Set the DBWR_IO_SLAVES parameter to greater than 0 only if the DISK_ASYNCH_IO parameter is set to false. Otherwise, the database writer process becomes a bottleneck. In this case, the optimal value on AIX for the DBWR_IO_SLAVES parameter is 4.
When using Direct Input-Output or Concurrent Input-Output with Oracle Database 11g, the AIX file system does not perform any read-ahead on sequential scans. For this reason the DB_FILE_MULTIBLOCK_READ_COUNT value in the server parameter file should be increased when Direct Input-Output or Concurrent Input-Output is enabled on Oracle data files. The read ahead is performed by Oracle Database as specified by the DB_FILE_MULTIBLOCK_READ_COUNT initialization parameter.
Setting a large value for the DB_FILE_MULTIBLOCK_READ_COUNT initialization parameter usually yields better Input-Output throughput on sequential scans. On AIX, this parameter ranges from 1 to 512, but using a value higher than 16 usually does not provide additional performance gain.
Set this parameter so that its value when multiplied by the value of the DB_BLOCK_SIZE parameter produces a number larger than the Logical Volume Manager stripe size. Such a setting causes more disks to be used.
A.2.6 Using Write Behind
The write behind feature enables the operating system to group write Input-Output together, up to the size of a partition. You can improve performance by doing this, because the number of Input-Output operations is reduced. The file system divides each file into 16 KB partitions to increase write performance, limit the number of dirty pages in memory, and minimize disk fragmentation. The pages of a particular partition are not written to disk until the program writes the first byte of the next 16 KB partition. To set the size of the buffer for write behind to eight 16 KB partitions, enter the following command:
To disable write behind, enter the following command:
A.2.7 Tuning Sequential Read Ahead
The information in this section applies only to file systems, and only when neither Direct Input-Output nor Concurrent Input-Output are used.
 - minpgahead
 - maxpgahead
-o minpgahead=32 -o maxpgahead=64
A.2.8 Tuning Disk Input-Output Pacing
Disk Input-Output pacing is an AIX mechanism that enables the system administrator to limit the number of pending Input-Output requests to a file. This prevents disk Input-Output intensive processes from saturating the CPU. Therefore, the response time of interactive and CPU-intensive processes does not deteriorate.
You can achieve disk Input-Output pacing by adjusting two system parameters: the high-water mark and the low-water mark. When a process writes to a file that has a pending high-water mark Input-Output request, the process is put to sleep. The process wakes up when the number of outstanding Input-Output requests falls lower than or equals the low-water mark.
You can determine disk Input-Output saturation by analyzing the result of iostat, in particular, the percentage of iowait and tm_act. A high iowait percentage combined with high tm_act percentages on specific disks is an indication of disk saturation.
A high iowait alone is not necessarily an indication of an Input-Output bottleneck.
A.2.9 Resilvering with Oracle Database
If you disable mirror write consistency for an Oracle data file allocated on a raw logical volume, then the Oracle Database crash recovery process uses resilvering to recover after a system failure. This resilvering process prevents database inconsistencies or corruption.
During crash recovery, if a data file is allocated on a logical volume with multiple copies, then the resilvering process performs a checksum on the data blocks of all the copies. It then performs one of the following:
On AIX, the resilvering process works only for data files allocated on raw logical volumes for which mirror write consistency is disabled. Resilvering is not required for data files on mirrored logical volumes with mirror write consistency enabled, because mirror write consistency ensures that all copies are synchronized.
If the system fails while you are upgrading an earlier release of Oracle Database that used data files on logical volumes for which mirror write consistency was disabled, then run the syncvg command to synchronize the mirrored logical volume before starting Oracle Database. If you do not synchronize the mirrored logical volume before starting the database, then Oracle Database may read incorrect data from an logical volume copy.
If a disk drive fails, then resilvering does not occur. You must run the syncvg command before you can reactivate the logical volume.
Oracle supports resilvering for data files only.

Students at D.C. schools are diving into a new academic subject: water conservation. Eaton Elementary in Northwest D.C. is one of 15 schools participating a program called Be Water Wise, which made its debut in Miami two years ago.
Eaton students are taking all their math, science and geography lessons and flushing them right down the toilet. Students there, with stopwatch and clipboard in hand, are making the rounds of their school's bathrooms.
Using the stopwatch, they measure the amount of water coming out of sinks and toilets. Then, they'll plot their findings on a graph, and use it to calculate the school's water bills.
Be Water Wise aims to directly engage students the a real world issue of water conservation and management, according to Diane Wood, president of the National Environmental Education Foundation, which created the program.
"What's fabulous about it is it really engages kids in science, math and language arts and lets them feel that the learning they're getting in the classrooms they can apply in their daily lives," says Wood.
In addition to the, ahem, field research, students will study the geography of the Chesapeake Bay Watershed, and learn new vocabulary words, such as aquifer and erosion. Fourth grader Pearl Benjamin says she's already learned a lot about her own impact on the world's water supply.
"At first I thought there's tons of water on Earth," Pearl says. "Now I see that we really have to start saving water."
And she has a message for her parents.
"They're not very good with saving water," she says. "I want them to remember when to turn things off and if they can turn they off for whatever they're doing, like washing the dishes. Which they don't normally do."
As part of the 18-month effort, students will install rain barrels and plant rain gardens to address the impact of stormwater runoff on the Chesapeake Bay. They plan to present their findings to city officials this spring.

Congruent Triangles - Two angles and included side (ASA)
Definition: Triangles are congruent if any two angles and their
included side are equal in both triangles.
There are five ways to test that two triangles are congruent. This is one of them (ASA). For a list see
If any two angles and the included side are the same in both triangles, then the triangles are congruent.
Drag any orange dot at P,Q,R. The other triangle LMN will change to remain congruent to the triangle PQR.
Notice that the the two angles and included side are drawn in thick blue lines to indicate they
are the parts being used to test for congruence.
What does this mean?
- Since two angles and the
are equal in both triangles, we can be sure the triangles are congruent.
- Because the triangles are congruent, the third angles (R and N) are also equal
- Because the triangles are congruent, the remaining two sides are equal (PR=LN, and QR=MN)
But don't forget:
Congruent triangles can be rotated and/or mirror images of each other (reflected).
(See Congruent triangles.)
In the figure on the right, the two triangles have all three corresponding sides equal in length
and so are still congruent, even though one is the mirror image of the other and rotated.

3.1 Incidental Influences on Total Soil Dust Ingestion: Dr. Natalie Freeman
Dr. Freeman's presentation focused on incidental ingestion of soil and dust that results from children's typical eating and mouthing behaviors. Though her most recent studies have primarily examined exposures to household dust, Dr. Freeman noted that 50-70% of household dust is believed to come from outdoor soils. Thus, she reports her results as ingestion of "soil/dust," rather than ingestion of strictly household dust.
Dr. Freeman explained that examining incidental soil ingestion among children is important, because national studies have suggested that 87% of children (aged 1-4 years) lie or play on the floor and nearly 50% play on grass or dirt. (Dr. Freeman acknowledged that these summary statistics reflect national trends and may not be representative of regional or local trends.) She added that her own research of children in Newark, New Jersey, has shown that a large proportion of children (aged 1-3 years) regularly engage in activities that can lead to soil ingestion, such as eating most of their food with their hands, eating food dropped on the floor, and putting their fingers in their mouths.
Dr. Freeman then outlined preliminary data she has collected in support of an ongoing "Children's Dietary Lead Study." She specifically addressed the extent to which children's food can be contaminated by their behavior patterns. This study characterized children's exposures to soil and dust in New Jersey urban centers by sampling levels of metals contamination on kitchen floors, children's hands, food that fell on the floor, and food that children handled. Dr. Freeman explained the approach used to attribute measured levels of metals in food to contributions from metals contamination in soils and household dust, and then presented preliminary results from her study. One preliminary result is that, on average (median), 2 mg of dust adheres to a slice of apple dropped on the floor, the maximum being 16 mg. Similarly, 8 mg of dust, on average (median), adheres to a slice of cheese dropped on the floor, the maximum amount being 59 mg. Based on her results for apples, cheese, bananas, and hot dogs, Dr. Freeman estimated that children, on average, may ingest 22 mg of household dust daily just from eating foods from the floor, with a 90th percentile ingestion rate from this activity of 93 mg.
Dr. Freeman also presented preliminary estimates of soil ingestion rates resulting from children's typical mouthing behavior. These estimates were calculated from measurements of the amounts of dusts typically found on children's hands and the assumptions on hand-to-mouth rates, the percentage of the hand that enters a child's mouth, the extent to which the amount of dust on the hand might be replenished between mouthing events, and the number of hours a day in which children engage in mouthing behavior. Not surprisingly, the results varied with the assumptions made in the calculations. For instance, children with a median dust loading on their hands (i.e., 1.5 mg dust per hand) who have a hand-to-mouth rate of 8.5 events per hour were estimated to have an incidental dust ingestion rate--from mouthing behavior alone--of 14 mg per day. At the upper end of the soil ingestion range, children with the maximum dust loading on their hands (i.e., 58.2 mg dust per hand) who have a hand-to-mouth rate of 27.0 events per hour are estimated to have an ingestion rate of 1,800 mg per day. Dr. Freeman noted that this elevated ingestion rate was not actually observed, but was estimated using a statistical analysis of her data. Dr. Freeman emphasized two assumptions that introduce uncertainty into these calculations. First, the dust loading on hands was assumed to fully replenish between mouthing events--an assumption that an observer suggested was conservative for the upper-end exposure scenario--and mouthing activity was assumed to be limited to 8 hours per day. Dr. Freeman explained that little data are available for soil/dust replenishment on hands, for mouthing activities during 24-hour time periods, and for the consistency of these behaviors across days or weeks. She noted that most observational studies are limited to 8 hours or less per child.
In conclusion, Dr. Freeman stressed that considerable amounts of soil and dust ingestion can occur on a daily basis as a result of children's typical behavior patterns, and not necessarily from what have traditionally been considered intentional soil-pica events.

Hierarchical refinement in isogeometric analysis for flexible multibody impact simulations
Detailed impact simulations in flexible multibody systems can be simulated based on reduced isogeometric analysis (IGA) models. However, a precise simulation of an impact requires a high element resolution in the contact area. Usually in IGA, global refinement methods are used, which are easy to implement. However, in the literature, also the use of hierarchical local refinement is proposed. The local refinement generates fewer countable degrees of freedom compared to an equivalent global refinement. Numerous application areas can be found in the literature, such as contact simulations, where the computational effort is reduced by local refinement. In this work, we introduce the inclusion of hierarchically refined IGA models within the floating frame of reference formulation. Thereby, the hierarchically refined IGA model is reduced and applied in impact simulations. In two application examples, we simulate the impact of twoand three-dimensional spheres and compare with an analytical solution. The focus here is on the comparison of calculation times and accuracy of globally and locally refined reference models. The third application example consists of two flexible double pendulums and is devoted to systems in which the bodies undergo both arbitrary rigid body motions and small elastic deformations.

Journal: International Journal of Sports Medicine - September 2020, Volume 42, Issue 3, Pages 270-276 (DOI: 10.1055/a-_PHONE_)
The purpose of this study was to examine the differences in neuromuscular control and mechanical properties of the ankle-stabilizing muscles between men and women, and during different phases of menstrual cycle in women. Fifteen women with regular menstrual cycles and 17 male counterparts were included in this study. Electromyographic signals were recorded from the peroneus longus (PL) and tibialis anterior (TA) muscles while performing three balance tasks.
Muscle tone, stiffness, and elasticity of muscles were measured using a MyotonPRO in the resting position. Outcomes were measured twice (ovulation and early follicular phases) for women, while measurements were acquired only once for men.
Significantly higher tibialis anterior-peroneus longus co-contraction (TA/PL ratio) was observed in all balance tasks in women than in men (p< 0.05); however, significant differences between phases of the menstrual cycle were noted only in the 2 most difficult tasks (p< 0.05). A similar pattern was observed in the postural sway.
Keywords: estrogen, menstrual cycle, mechanical properties, sex-difference, lower limbs, neuromuscular activation
These results highlight the importance of sex-specific hormonal effects on neuromuscular control and mechanical properties, and as well as the differences during phases of the menstrual cycle. These insights assume significance in the context of developing neuromuscular strategies for the purpose of preventing lower extremity injuries during sports activities.

Key Words: ANESTHETICS, Inhalational
JUSTIFICATIVA Y OBJETIVOS: Estudios clínicos y experimentales han sido desarrollados para identificar los locales donde los anestésicos (inhalatorios) actúan y para determinar cuales las alteraciones funcionales que eses fármacos producen en las estructuras del sistema nervioso central, determinantes del estado de anestesia que es observado clínicamente. El objetivo de este trabajo es describir los resultados obtenidos por varios autores en estudios clínicos y experimentales realizados recientemente en la tentativa de esclarecer los mecanismos de acción de los anestésicos inhalatorios en el sistema nervioso central.
CONTENIDO: Para facilitar la comprensión de los complejos mecanismos de acción de los anestésicos inhalatorios en el sistema nervioso central, ellos fueron divididos en tres niveles: el macroscópico, el microscópico y el molecular. Recientemente un grupo de autores describieron estos mecanismos de acción en: orgánicos, celulares, e inhibidores de la entropía. Estos mecanismos tentarían explicar el estado de anestesia que tendría como característica la capacidad de prevenir al paciente dos acciones principales: 1) inmovilidad, inhibición de la respuesta a estímulos nociceptivos; y 2) amnesia. Otros efectos (deseables) también son obtenidos por la administración de anestésicos: analgesia e hipnosis. Entretanto, tales efectos sea aisladamente o juntos, no definen el estado de anestesia. Teniendo como base estos conceptos, este grupo adopta y divulga la clasificación de los anestésicos en: 1) anestésicos completos, los que producen inmovilidad y amnesia; e 2) incompletos o no inmovilizantes, los que no producen inmovilidad más producen amnesia.
CONCLUSIONES: De acuerdo con los resultados de varios estudios realizados recientemente, probablemente la amnesia y la inconsciencia ocurren por la acción del anestésico predominantemente en el cerebro, en cuanto la inmovilidad, o sea, la inhibición de la respuesta al estímulo nociceptivo por movimiento, seria por la acción del anestésico preferencialmente e inicialmente en la médula espinal. Estas acciones ocurren por inhibición de la transformación de energía (entropía) que forma los potenciales de acción en las células (fibras) nerviosas, especialmente en las sinapsis.
Pharmacological anesthetic action is defined based on clinical effects. Its mechanism, however, is not easily understood because it has not yet been clearly and objectively explained. Clinical and experimental studies are recently being developed to identify anesthetic action sites and functional changes produced on central nervous system structures and which would determine clinically observed anesthetic status.
The inhalation of an anesthetic agent for some minutes and in a given concentration will clearly make the individual unconscious and with no reaction to painful stimuli. Searching in the literature to understand such drug action, we have found a wide variety of publications showing actions on the brain cortex explained by changes in EEG waveforms. Actions on the brain stem, from the ascending activator reticular system (AARS) to the hypothalamus, thalamus and spinal cord have also been described.
In the past there was a concept that low anesthetic concentrations would develop a state of unconsciousness or hypnosis which, when increased, would produce muscle relaxation and immobility. Currently it is known that several anesthetics may have different pharmacological actions in low concentrations, according to their characteristics. This has been recently shown both in clinically used anesthetics and in experimental agents.
Such actions are part of pharmacodynamics, that is, the explanation of a physiological change to obtain a certain clinical result by the drug's action on the CNS. Some experimental studies have tried to describe cellular and molecular mechanisms which could inhibit nervous impulse transmission and produce a state of anesthesia.
Since the analysis of such mechanisms is rather complex, they were divided in three levels: macroscopic, microscopic and molecular 1. Some authors have recently classified such action mechanisms in organic, cellular and entropy inhibitors 2-4 in an attempt to explain anesthetic status aiming at providing patients with two major reactions: 1) immobility, or response inhibition to noxious stimuli; and 2) amnesia. Other equally desirable effects, such as analgesia and hypnosis, are also obtained by anesthesia, however the latter, per se or in combination, does not define anesthetic status 5.
These concepts were the basis for the following classification: 1) complete anesthetics, inducing immobility and amnesia; and 2) incomplete anesthetics or not inducing immobility but inducing amnesia 3,6.
CNS is the primary action site for anesthetic agents. There are reports on their action on different CNS organic sectors. It has been difficult to specifically determine the site where nervous impulse conduction discontinuity starts to produce amnesia, unconsciousness and immobility; recent experimental studies, however, have shown evidences of such complex process.
Action on the Brain
In the past it was believed that general anesthetics would act only on the brain and that the state of anesthesia would be simply a consequence of such pharmacological action in a higher or lower intensity.
In fact, there are very feasible reasons to accept this concept. Brain stem and all attached organs making up the encephalon were considered as brain. Currently it is known that, although an arguable anesthetic action on the brain, being it the primary information integration site, it is possible that such drugs would act on its structures, especially the synapses, interfering in memory and alertness. However, there are no evidences of total cortical activity inhibition by anesthetic agents. On the other hand, it has been shown that some synapses may be inhibited and others excited by different anesthetics 7-9.
An experimental study with ewes 10 has shown that isoflurane alveolar concentration to inhibit motor response to painful stimuli is more than twice when the brain is preferentially anesthetized, as compared to anesthesia distributed throughout the body. In this experimental model using partial bypass with preferential circulation to the brain, 2.9% isoflurane alveolar concentration was needed to inhibit motor responses to painful stimuli, while with normal circulation, 1.3% was enough. The conclusion was that subcortical structures, including spinal cord, are very important for motor response to painful stimuli.
It has been shown in experimental rats that anesthetic inhibition of motor responses to noxious stimuli is independent of brain cortex structure 11. Rats were anesthetized with 1.3% isoflurane alveolar concentration and presented a satisfactory motor response to noxious stimuli. After brain cortex aspiration, motor response inhibition to noxious stimuli was obtained with virtually the same concentration (1.26%). Alveolar concentrations were established after incremental administrations and motor inhibition as response to noxious stimuli was investigated.
Non immobilizing or incomplete anesthetics have less pronounced and well selective action on CNS structures.
Complete or immobilizing anesthetics, such as isoflurane, are effective in inhibiting fear-conditioned learning and in depressing medium latency auditory evoked potential (MLAEP), while non-immobilizing agents, such as dichlorohexafluorcyclobutane, interfere in learning but do not change MLAEP. This was experimentally shown in rats 3. In a different study it has been observed that isoflurane changes thermoregulation in rats, while dichlorohexafluorcyclobutane does not 12.
It is known that the auditory evoked potential is transported by the brain stem via lemniscus and AARS. Thermoregulation is subcortically controlled, while learning depends on memory which is coordinated in the brain.
For what has been said, it is understandable that brain areas associated to memory and consciousness are more sensitive to inhalational anesthetics than subcortical areas associated to transmission and control of other functions, such as auditory afference, thermoregulation (brainstem) and stimulated movement (spinal cord).
As a consequence, it may be said that amnesia and unconsciousness are a result of the


Romance or romantic? I like romantic movies or I like romance movies? are both correct? Also, a friend of mine said it's all right to say: It's a romantic movie. But it's wrong to say: It's a romance movie. Why is that? Thanks!

"Romance movie" is absolutely correct and more common than "romantic movie". ROMANTIC is an adjective. "A romantic movie/book" "A romantic night" "A romantic poem/story" ROMANCE is a noun. "It was a short-lived romance" It can also be an adjective when used to describe a type of writing: romance novels.

I would disagree with Marcin about 'romance movie' being more common than 'romantic movie'. Certainly you can say that the story is 'a romance', the same way as you'd describe a story as 'a thriller', but I would always use the adjective form before'movie' or film: 'a romantic movie' or 'a romantic film'. Out of curiosity, I googled this and found one or two references to 'romance movie' and dozens to 'romantic movie'. This could be a regional difference, but I have never actually heard anyone say 'romance movie'.

After this by selecting Play all messages once, Play all

sage to play. All these commands are controlled using a
GUI (Fig. 10). It is also possible to change the coordinates of the reference point (The coordinates of messages
given in the text file are referenced to this point) and the
size of the message area (radius). The localization of the
user is done by a head-tracker which sends the coordinates of the user to the application. When user, wearing
a detector, is inside a message area, the message is played
if selected command allows that.
The current version of the auditory Post-it application
works well when the messages are located not more than
1-1.5 m from the head-tracker. However, with better
tracker it should be possible to detect messages from a
larger area. The next improvement to the auditory Post-it
application will be the implementation of the possibility
to leave a message while an application is running. In the
current version messages have to be defined beforehand.
Calender application
The last implemented application is a 3-D audio calendar reminiscent, based on the idea presented by Walker
et al. [40]. The user can record calendar entries and
place them into directions corresponding to the time of
the day: 9 A.M. at -90 degrees azimuth (left of the user),
noon at 0 degrees, three o'clock at +90 degrees (right of
the user) and so on. The calendar application was implemented in two versions: head-tracked and non-headtracked. The head-tracked version spins the calendar entries around a reference point (which is specified relative
to the transmitter of the head-tracking system) and the
non-head-tracked version obviously has the user's head
as the only reference point.
The calendar application seems to work quite well, even
though it certainly would help to have an easier interface
to it, some kind of external controller device with which
the user could browse through the calendar entries.
In order to send an acoustic environment from one place
to another and then make it audible there is a natural
need for microphones to record the environment or the
communication and transducers to make the sound audible. As the system is aimed to be worn all the time, the
transducers have to be small and light. Nowadays some
people are wearing headphones throughout the day to listen to music. Adding a microphone to headphones could
then be a logical way to make a two-way transducer system to record and reproduce the sound.
For augmented reality purposes it would be ideal if the
surrounding and the augmented acoustic environment
could be totally controlled with the headset. To achive
this the headset should block the surrounding sounds
as effectively as possible and simultaneously play the
acoustic environment back to the user. With headsets
there are practically two ways to attenuate surrounding sound: in-ear passive earplugs and active noise cancelling headphones. Traditional passive hearing protectors would be effective but rather unpractical for this matter. There are various application-dependent headset systems available in the market. Most models rely on passive background noise rejection caused by tight fit of the
headset inside the ear canal - though working like a traditional earplug. To get more attenuation at low frequencies some models have added electronics to cancel out
background noise. There is a small microphone in the
earplug and the signal it detects is fed back to the earplug
in inversed phase. In some more advanced models there
are two microphones and a separate DSP unit for processing the signals. The microphone signal is not available as an output in these headset systems. On the other
hand, there are systems where the microphone signal is
available either for communication or recording use. Table 1 lists some of the headsets available in the market,
that have some relevance to the system considered in this
6.2 Head-trackers and location devices
Many of the applications discussed in this paper are
based on knowledge of the location or orientation of the
user. In the following presentation we roughly follow the
taxonomy introduced in a recent review article [41].
In WARA applications, tracking of user's location and
orientation takes place at least on two levels. First, in
some applications we may be interested in the global position of a user, where the system is aware of the physical coordinates, such as in using the Global Positioning
System (GPS), or the emerging European Galileo positioning system. Global information is typically needed
in applications in which augmented acoustic events are
localized to known real world objects (such as the Central train station, the parking lot of movie theater, or the
department copying machine). An overview of different
techniques operating at global, metropolitan, building, or
room level are given in [41]. Global position information
is needed to launch an application related to some object.
In this article we put more emphasis on the problem of
head-tracking. Estimates on the short-range relative location and orientation of the user's head are needed for
successful augmentation of the acoustic environment.
The three major techniques for location-sensing are triangulation, proximity and scene analysis. Triangulation
can be done via lateration, which uses multiple distance
measurements to know points or via angulation, which
measures bearing angle relative to points with known
separation. In proximity technique the distance to a
known set of points is measured and in scene analysis
a view from a particular vantage point is examined.
GPS The Global Positioning System (GPS) is the most
widely publicized location-sensing system at the moment. GPS is a satellite-based navigation system made
up of a network of 24 satellites. The system is governed
by the U.S Department of Defense. GPS satellites circle
information and use triangulation to calculate the user's
exact location. Essentially, the GPS receiver compares
the time a signal was transmitted by a satellite with the
time it was received. The time difference tells the GPS
receiver how far away the satellite is. With distance measurements from a few satellites, the receiver can determine the user's position. The accuracy of the system is
around 1-5 meters. The system doesn't work reliably indoors. [42]
GALILEO The Transport Council of the EU started
GALILEO project in 1999. The system is a satellitebased global positioning system and is inter-operable
with other systems such as GPS and UMTS. The
GALILEO will cover all European states. The services
offered are divided in three distinct services: GeneralPurpose, Commercial and Public-Utility Services. The
General-Purpose Services will be available for everybody without any need for authorisation. The accuracy
will be 5-30 meters depending on technology. The Commercial Services provide an accuracy of 1-10 meters and
are available as added value services on payment of a fee.
The Public-Utility Services will provide a highly secure
and accurate services for safety-of-life and other critical
applications. The accuracy will be 1-6 meters. By the
end of 2007, GALILEO should be fully operational.[43]
Active Badges Active Badge is an indoor locating system developed at the AT&T Cambridge. The system consists of a central server, fixed infrared sensors around the
building and badges worn by the users. The badges emit
a globally unique identifier every 10 seconds or on demand. A central server collects this data and determines
the absolute location of the badge by using a diffuse infrared technique. The system can only tell the room
where the badge is. On the other hand, the badge may
have globally unique ID (GUID) for recognition. Sunlight and fluorescent light interfere with infrared.[41]
Active Bats Also developed by the AT&T researchers,
the Active Bat location system uses an ultrasound timeof-flight lateration technique to provide a physical location of the Active Bat tag. The tags emit ultrasonic
pulses, synchronized by radio frequencies, to a grid
of ceiling-mounted sensors. The distance measurement
data is forwarded to a central unit that calculates the position. The accuracy is 9 cm at 95 percent of the measurements. The tags can have GUID's for recognition.[41]
Cricket Instead of central computing, the Cricket Location Support System lets the user calculate the location. The infrastructure consists of infrared transmitters
and the user objects act as receivers. Radio frequencies
are used for synchronization and to delineate the time
region during which the sounds should be received by
receiver. A randomized algorithm allows multiple uncoordinated beacons to coexist in the same space. Cricket
implements both the lateration and proximity techniques.
The user can be located in around an area of 1.2 x 1.2
square meters within a room. Because all the computation is done at user side the power issues in wearable
devices may become a burden.[41]
RADAR RADAR, developed by the Microsoft Research group, is an RF-based location system using the
IEEE 802.11 WaveLAN wireless networking technology. At the base station, the system measures the signal
strength and signal-to-noise ratio of signals sent by wireless devices. This data is then used in computing the 2D
position within the building. There are two implementation for RADAR: one uses scene analysis and

Gobetwino is not restricted to work with Arduino, the serial port can be configured so it can work with most devices that can send and receive strings over a serial line.
Gobetwino is listening on the serial port, for "commands coming from Arduino, and in response it will do something for Arduino and possibly return something to Arduino.
Gobetwino defines a set of command types that can be used as templates to create actual commands. Arduino can ask Gobetwino to execute these commands, and return something to Arduino.
So what can Gobetwino do? Using the defined command types you can create commands in Gobetwino that Arduino can ask Gobetwino to execute. These commands
With combinations of these commands you can do things like:
 - Start any program on your PC, either directly or via an associated file type.
 - Start Excel, send data from Arduino directly into the Excel sheet, save the sheet and email it, without touching your PC.
 - Send e-mails to a POP3 mailbox and have Arduino react to the contents of the emails.
 - Log data directly to a CSV file on the PC, so the data can be used in spreadsheets or databases.
 - Download a file from the internet and have Arduino ask for a specific line of data from the file.
Gobetwino is kind of a "genreric proxy" for Arduino. It's a program running on a PC (Windows only - sorry), that will act on behalf of Arduino and do some of the things that Arduino can't do on its own. So it works like a go between, hence the name.
Gobetwino is free, comes with a detailed user manual, and sample Arduino sketches to show how it can be used.
Gobetwino can be downloaded here.
Check my blog for information about updates, user suggestionns, and bugs.
The current version is to be considered a beta version, it probably still has bugs in it, and no long time stability test has been performed yet.
If you have comments, questions or whatever, mail me at:

I'm having a really hard time understanding your problem/question. Perhaps you can rephrase?
Please see the 2 screen shots. If you look at the Y axis in each of the shots you will see that the numbers are different, however the only difference between the 2 sheets is thta one includes the dimension "Tier" and the other does not. The totals in both cases should be the same. In ExcludingTier sheet, I would expect to see the total of ~9k(as a can be seen in the IncludingTier chart).
An Area Chart will always sum values visually. You are summing averages. For example:
if you have 10 people with test scores averaging 95% then you have one level of detail at.95.
If you decide to graphically represent test score averages of men and women then you get two values (Hypothetically 91% and 98% distribution isn't relevant) With an area chart you are now representing.91 +.98 getting a total axis of 1.89. You can't ask what you're asking with an area chart and expect to get your desired result. Is there another way you would want to represent multiple averages?
To better describe the problem. If you look at the data, for a given day a "Job_Name" can appear more than once, if this is the case then I would like to take the average time it took to run that job for that day. I would then like to plot for each day the total/sum of the average times it took to run each of the jobs defined in "Job_Names".
In the example data, for the 6th, there are 4 jobs:
A, this was run twice with run times of 3010+3012 so average is 3011
C, this was run once with time of 3120
D this was run once with time of 3040
So the total time take to run all 3 jobs is 9171.
However when you plot this in a graph the total is calculated as the avg(3010+3012+3120+3040)=3045.5 which is not displaying the same information as 9171.
Basically I was to view a graph of total time take to run jobs as opposed to the average run time of all jobs.


This print can be thought of as a "raw" copy of one of my brushstroke negatives, which I have been cutting up for my collages before transferring them to the final support paper.
What I find interesting about the collage process is that at each step of the way the visual information is further and further removed from its original context, and given new meaning based on the the new configuration within which it finds itself. In photographic terms this relates to not just the image that is printed, but also the process by which it is printed. As previously mentioned, I chose the carbon transfer process for my prints because of the unique characteristic of relief that it offers, but this is not the only process I've used, and I continue to experiment with other methods for representing the same information.
This minimalist, grid style is nothing more than an organised way of practising single brushstrokes within a predefined area that renders them useful and interesting in both their unaltered form and as individual parts of a collage. So while originally a rectangle as a consequence of me maximising the use of the film surface on which I paint, the form has evolved into a square in order to serve multiple purposes.
A selection of early cyanotype prints in rectangular form, that due to the speed of the process, allowed me to proof my negatives before deciding which ones I'd make as carbon-transfer prints.

Dallisgrass vs Crabgrass – Differences and Identification
If you're a homeowner, you know your pride and joy is having a lush, green lawn that is the envy of your neighbors. However, it's not an easy task maintaining your lawn and sometimes you may come across the dallisgrass or crabgrass growing on your lawn.
Dallisgrass and crabgrass are both weeds that find their way onto your lawn and disrupt the beauty of your lawn. These two weeds are clumping grasses and may look similar, but there are a few differences you'll find between the two weeds.
Type of weed
Control and prevention
Hollow leafless stalk, serrated comb, and tooth-like leaves, yellow petal flowers mature to white puffballs
If only a few dig them out to remove by hand, pour boiling water, or use a broadleaf herbicide
Yellow nutsedge
Grass-like leaves with a v-shaped cross-section, golden-brown flower spikelets, hairless triangular stem
Remove by hand, use sugar, use a herbicide
Arrow-shaped leaves, white/blue/purple flowers, thick stem
Cut it at ground level, pour boiling water, use a non-selective herbicide
Wide leaves, rough blades, thick white roots
Regular overseeding your lawn, dig out all the roots, frequent mowing, spot spray a non-selective herbicide
This is a warm-season perennial grass that can reach up to 5 feet. It's a robust, clumping, coarse-textured grassy weed that invades all types of turfgrass. It grows in an ever-enlarging circular clump that gets so large at times that the center dies and the outer rings continue to grow. It's a difficult weed to control and it thrives in clay or sandy soils. Dallisgrass reproduces by very short rhizomes and seeds in the summer and tends to do very well where there's lots of foot traffic and your desired grass gets beat down. This makes this unsightly grass weeds a nightmare for your turfgrass. Most people confuse the dallisgrass with crabgrass.
How to identify Dallisgrass
 - Dallisgrass grows fuller and taller while crabgrass grows outward.
 - It has a distinguishing clump that gradually grows circular and its short rhizomes increase its diameter and store carbs.
 - It grows in a way that is difficult to control because it can be difficult to pluck out of the grass because of its fibrous thick roots which can reach up to 1 m deep.
How to kill dallisgrass
 - You can control dallisgrass by maintaining a healthy, dense turf through ensuring you properly water, mow, and fertilize your lawn. Also quickly fill the bare spots with sod or seed to prevent the weed seeds from invading your lawn.
 - Also, use pre-emergent control herbicide that is toxic to crabgrass can also be effective in killing dallisgrass. Ensure your water to allow the herbicide to penetrate the soil.
 - Lastly, you can also post-emergent treatments like digging the weed out which is labor-intensive, or using a post-emergent herbicide that you would use on crabgrass and apply it several times at 2-3 weeks interval to prevent regrowth.
This is a summer annual weed grass which means in most climates it only grows once a year produces seeds then dies off. It has wide flat blades and produces long flower clusters and lots of seeds per season. Although crabgrass is invasive, it's not competitive so it will only appear when your lawn is weak and unhealthy. It grows outward in a roughly star-shaped pattern that tends to grow close to the ground. It spreads through new shoots of grass that grow a bit far from the center of the clump and will continue to spread to more than a foot in diameter if left unchecked.
There are two different types of crabgrass, smooth crabgrass with no hairs and the hairy type with hairs all over the plant.
How to identify crabgrass
 - The blades are angled out from the stem and grow continuously as new blades appear.
 - As it grows, the seedlings develop side shoots that develop into separate branches.
 - The leaf blades are long and a bit wide.
How to prevent crabgrass
 - One of the best ways of preventing crabgrass from growing on your lawn is to ensure the lawn is growing thick and healthy without any bare spots.
 - Also, use a pre-emergent herbicide to create a protective barrier in your lawn that will prevent the growth of crabgrass seeds.
 - A post-emergent herbicide will kill all the crabgrass already growing on your property.
Differences between dallisgrass and crabgrass
Type of weed
Dallisgrass is a perennial weed grass that is difficult to control because it doesn't die once the season ends, it just stays dormant. However, crabgrass is an annual weed grass whose lifecycle only lasts one season so it's easier to control than dallisgrass.
Mode of spreading
Dallisgrass is a course-textured clumping grass that spreads from short thick rhizomes that continue to grow a deep underground stem. The clumps are thicker and stiffer than other types of grass which can trip you if you're walking across your lawn. However, crabgrass spreads using the same method but it spreads using a star-shaped pattern that grows to form a thick mat and develops side shoots that become separate branches once they grow.
Where it grows
Dallisgrass thrives in sandy and clay soils and will grow rapidly in nitrogen fertilizer to twice as much as your regular turf grasses which can create an unsightly turf. It can invade all types of turf grasses and spread rapidly which makes it very hard to control. The crabgrass on the other hand only grows where there are bare spots on your lawn so growing a thick lawn grass can be effective in controlling it.
Since it's difficult to get rid of grass weeds like dallisgrass and crabgrass once they become established, it's best to ensure you always keep your lawn thick and healthy. Also, keep an eye on your lawn to check for weeds and act fast to treat them.
Will vinegar kill dallisgrass?
Using vinegar at home can kill dallisgrass in no time, however, be careful when applying the vinegar on the leaves.
What's so bad about crabgrass?
Crabgrass is an opportunistic weed that will usually grow in bare or thin parts of your lawn and can also crowd-out the good grass that has been weakened by mowing too short, affected by the disease, insects, or other problems.

the user can be root on that system and could then change the IP address to gain access to the system, mount a filesystem, and copy data from the server. However, if root is squashed to user nobody, then root will have the same privileges given to all users, thus preventing a compromised system from allowing root to pull data from your system.
On the other hand, if you want root to have access to an NFS-mounted filesystem, you can add the option no_root_squash to the file /etc/exports to allow root access. Just be aware that if someone reboots your system to gain root access, it's possible for them to copy (steal) data.
In this article, I presented various options you could use to improve performance on an NFS filesystem, although depending on your circumstances, they might not help or might even result in reduced performance. Some of these tuning parameters are NFS options, whereas others involve changes to the system that improve performance or are options for managing NFS filesystems. The best way to judge which options are useful is to run tests, particularly with the applications you plan on running.

1. Field of the Invention
The present invention generally relates to usage of a telecommunication company's fiber to the premises (FTTP) installation at customer premises and, more particularly, relates to the customer's controlling of features associated with a batterybackup unit (BBU) used for powering an optical network terminal (ONT) associated with the FTTP installation during power failures.
2. Description of Prior Art
Fiber optic infrastructure is currently being deployed by certain telecommunication companies, including the assignee of the present invention, and being operatively connected to their respective customer bases. Fiber optic telecommunicationinfrastructure offers many advantages over the old standard copper wire cabling, not the least of which is vastly increased bandwidth. The plain old telephone system (POTS) had operated, and still operates, with copper wiring. POTS is now being madecompatible with fiber optic cabling.
However, a POTS telephone system in combination with this new fiber optic infrastructure involves certain optically-related and/or other functionality not previously needed in the copper wire cabling world. For example, an optical line terminal(OLT) is needed which may be located in the central office of the relevant telecommunications company or at some other regional location (but not on customer premises). The OLT is communicatively coupled via fiber optic cable to the ONT which isnormally located immediately outside of a customer's premises (typically mounted on an outside wall some four-five feet above ground).
The ONT is powered by a power supply such as, for example, a power supply similar, or related, to that described in patent application Ser. No. 11/144,566 filed Jun. 3, 2005, claiming benefit of provisional application Ser. No. 60/576,675filed Jun. 3, 2004, its assignee, and inventor being, in common with those of this instant application entitled: "Multi-Component ONT Power Supply" and incorporated by reference herein in its entirety. That power supply is, in turn, powered by typicalelectric utility company power which is subject to power failure for reasons including, without limitation, natural disasters and terrorist attacks. During a utility company power failure, traditional POTS telephone service over copper wiring isordinarily able to continue because of POTS battery back-up infrastructure which is in place at telecommunication company central offices. This battery backup system is designed to maintain POTS telephone service for an entire community. But, thatotherwise-available emergency POTS telephone service shall not be available to a telephone customer using a FTTP system, if the ONT cannot communicate with the OLT over the fiber optic cable because the ONT lacks power due to that power failure.
To this end, battery backup has also been provided within the FTTP environment for the ONT and for customer telephone instruments connected to that ONT. But, in contrast with the central office location of POTS battery backup, ONT batterybackup is located proximate its associated ONT, generally within, or near, the telephone customer's premises. This ONT battery backup unit (BBU) can be designed to include certain customer-useful features. One example is an alarm which sounds when thebattery voltage level is low. However, an incessant sounding alarm can be an annoyance and, to compound the annoyance, the alarm is itself using battery energy when emitting sound. These features, under certain circumstances, can therefore be adetriment instead of a benefit to the customer. There is, therefore, a need for managing these features in a manner that reduces or eliminates any customer annoyance otherwise generated by these features. The present invention provides a solution tothis shortcoming of the prior art.
Embodiments of the present invention include methodology and apparatus for managing an optical network terminal under conditions of a general power failure. More specifically, the present invention relates to managing certain automaticindicators of battery-backup voltage level for the optical network terminal in a manner to allow the customer a measure of control over these indicators.
In a particular embodiment, the present invention relates to a residential fiber optic communication system powered by electricity from a utility company. The system permits communication via customer premises equipment (CPE) including atelephone in a normal mode of operation. An OLT is located remotely from the customer premises, and can be located in a central office of the telephone company associated with the customer's telephone. An ONT is located at the customer premises and isin communication over a fiber optic cable with the OLT. A DC power supply is located at the customer premises for purpose of supplying electrical power to the customer's ONT and to the customer's telephone(s) via the ONT. A rechargeable battery backupunit (BBU) is located at the customer premises and is rechargeable by the power supply. The BBU is operatively coupled to the ONT and to the customer's telephone(s) via the ONT for the purpose of supplying substitute electrical power to the ONT and tothe telephone(s) if and when the utility company electric power fails.
A battery output sensor and controller are located at the customer premises for monitoring output level, such as output voltage, of the battery being used for backup. The controller includes means for automatically signaling the ONT to go intoa sleep mode to conserve power when the utility company electric power fails and the battery output level is reduced to a first level. The ONT includes means responsive to an off hook telephone signal for over-riding operation of the automaticallysignaling means and thereby reverting the sleep mode back to the normal mode of operation to permit the customer to place a call from the telephone over the system. After the call is completed, the system may automatically go back to the sleep mode.
However, during a utility company power failure where the output level has been reduced to an emergency level lower than the first level but greater than zero, the controller automatically signals the ONT to power-down completely. An emergencyswitch is connected between the output of the BBU and the ONT and is operable by the controller to disconnect the output of the BBU from the ONT. But, before that disconnection occurs, the ONT notifies the OLT over the fiber optic cable of thepower-down signal. That disconnection stops all further power dissipation from the BBU through the ONT. However that emergency switch is also manually-operable by the customer to permit power to be re-supplied to the ONT from the BBU to allow thecustomer to make an emergency telephone call over the fiber optic cable. Typically, the customer would make that emergency call and then open the emergency switch to continue to conserve BBU energy or power.
In yet an additional feature of the present invention, an audio alarm provides an audible warning under conditions of a failure of electrical power from the utility company. Typically, this may occur when the BBU output voltage is at a lowlevel approximately equivalent to the emergency mode level, although this level may fall within a range of levels running from a non-zero level below the emergency level up to the fully charged battery output level. This audible alarm battery voltagelevel is selected by the telecommunications company which is supplying this system. But the customer also has a measure of control. An audio alarm switch, operable by the customer, is provided which shuts-off the audio alarm for a predetermined timeselectable by the customer when the BBU output level is at or below this audible alarm battery voltage level, and after which time the audio alarm automatically sounds again.

Proposed NJ Flood Hazard Act Rules May Face A Legislative Veto
2015 saw major revisions proposed to New Jersey's Flood Hazard Area Control Act rules, Coastal Zone Management rules, and Stormwater Management rules. The rule amendments were billed by the New Jersey Department of Environmental Protection (NJDEP) as comprehensive changes to the rules to "reduce unnecessary regulatory burden, add appropriate flexibility, provide better consistency with Federal, local, and other State requirements, and address implementation issues." The rule changes consolidated permitting requirements between the three programs and removed certain regulatory burdens such as the 150-foot riparian zone regulatory standard for development in areas containing acid-producing soils. The proposal received criticism from State environmental groups, and on January 11, 2016, the Legislature voted to block the rule changes. The NJDEP Commissioner is currently working within a thirty-day window to amend or withdraw the proposed rules or the Legislature may, by passage of a concurrent resolution, invalidate the proposal. The resolution of this issue is worth watching as the proposed rule changes will have a direct impact on development throughout the State.


Managing Databases with Command Line SSH

Using SSH can be a superior way to manage the files and databases on your account. Using a simple command you can import or export a MySQL database into an existing database on your account.
Please note that in the examples below the -p will prompt for your account's password. And that your database name needs to include your username, e.g. examplec_database.
Exporting MySQL Data
 1. Using SSH, execute the following command:
 mysqldump -p -u username database_name > dbname.sql
 2. You will be prompted for a password, type in the password for the username and press Enter. Replace username, password, and database_name with your MySQL username, password, and database name.
The file dbname.sql now holds a backup of your database and is ready for download to your computer.
To export a single table from your database you would use the following command:
mysqldump -p --user=username database_name tableName > tableName.sql
Again you would need to replace the username, database and tableName with the correct information.
Once done the table specified would then be saved to your account as tableName.sql
Import A MySQL Database
The file must be in.sql format. It cannot be compressed in a.zip or.tar.gz file.
 1. Start by uploading the.sql file onto the server
 2. If you haven't already done so, create the MySQL database via the cPanel.
 3. Using SSH, navigate to the directory where your.sql file is.
 4. Next, run this command:
 mysql -p -u username database_name < file.sql
To import a single table into an existing database you would use the following command:
mysql -u username -p -D database_name < tableName.sql

Thaddeus Lowe in his balloon "Intrepid"
3-D Photos from the Civil War
Thaddeus Lowe, one of the first and best known aeronauts for the Union army, rises from the ground in Intrepid, the largest balloon in the Federal inventory. This photograph, taken on May 31, 1862, near Fair Oaks, Virginia, shows Lowe standing in the basket beneath his inflated balloon. Union soldiers below are holding onto the tethers that keep Lowe's balloon from drifting away.
Photo: Library of Congress, 3D Anaglyph by Garry Adelman
Thaddeus Lowe was reportedly quite the self-promoter. He regularly invited photographers and journalists to visit his camp and to see his balloons in action. It didn't hurt that Lowe ensured that his camp was stocked with the best food and ample forage for visiting horses. Nevertheless, information gathered from Union balloons during the Seven Days campaign was sought after by Army of the Potomac generals. Reaching altitudes of 1,000 feet, aeronauts in balloons like the Intrepid could see all the way into Richmond itself, more than seven miles from this position.
When placed into a special viewer, popular during the Civil War, viewers could see images like this famous Fair Oaks balloon image in 3D.

When Can Babies Go in the Bathtub?
Babies can go in the bathtub as soon as they are born, but it is important to take extra precautions when bathing a newborn. It is recommended that babies be bathed on a flat surface such as a changing table or countertop until they are at least 6 months old. This helps to ensure that the baby is supported and secure while being bathed.
Bathing a Baby Under 6 Months Old
When bathing a baby under 6 months old, it is important to use lukewarm water and avoid submerging them completely. Instead, use a damp cloth or sponge to gently clean their body. Make sure to keep one hand on the baby at all times to ensure their safety. It is also important to avoid using any soaps or shampoos until the baby is at least 3 months old.
Bathing a Baby Over 6 Months Old
Once your baby is over 6 months old, you can start introducing them to the bathtub. Make sure the water temperature is comfortable for your baby and never leave them unattended. You can use mild soap and shampoo specifically designed for babies. Be sure to rinse off all of the soap thoroughly before taking your baby out of the tub.

ADO.NET implements three basic forms to locate Rows - The Find method as applied to the Rows collection, the Find method as applied to the DataView object and the Contains method as applied to the Rows collection.
DataRowCollection Find and Contains Method
The DataRowCollection is a major component of the DataTable. While the DataColumnCollection defines the schema of the table, the DataRowCollection contains the actual data for the table, where each DataRow in the DataRowCollection represents a single row.
You can call the Add and Remove methods to insert and delete DataRow objects from the DataRowCollection. You can also call the Find method to search for DataRow objects that contain specific values in primary key columns, and the Contains method to search character-based data for single words or phrases.
DataView Find and FindRows Method
Using the Find and FindRows methods of the DataView, you can search for rows according to their sort key values. The case-sensitivity of search values in the Find and FindRows methods is determined by the CaseSensitive property of the underlying DataTable. Search values must match existing sort key values in their entirety in order to return a result.

Can you really resist a video called "Cat Smells Another Cat's Fart?"
No, you can't.
Much like our feline friend cannot resist sniffing another cat's butt, you are drawn to this clip because "Cat Smells Another Cat's Fart" is why the internet was invented.
Fun fact -- way back in the '60s when the internet was merely some sort of abstract idea, all those poindexters in their lab coats and ties pushed the tape on their glasses onto the bridges of their noses and proclaimed, "We need to create this interconnected series of computer networks so people can watch videos of cats not only breaking wind, but other cats sniffing their rear ends in the derision and annoyance that only cats can adequately express." Cats smelling farts are the original cat videos of the internet.
So, how about that? In addition to seeing a cat sniff a fart, you got a lesson in the obscure history of the World Wide Web. Animals should pass gas more often, right?

I have the question:
compute $\phi(24)$ for each element Z/24 decide whether the element is a unit or a zero divisor, if the element is a unit divisor give its order and find its inverse.
Ive worked out $\phi(24)=8$
and the unit divisors to be ${1,5,7,11,13,17,19,23}$
however when I came to working out the order I got them all to be 2?

Presumably, you mean all but one of them has order 2. – Gerry Myerson Nov 28 '12 at 12:16
yupp bar the number 1, could you confirm ive answered it correctly or have i gone terribly wrong? – jill Nov 28 '12 at 12:18
_USER_ You can write $(\mathbb{Z}/24)^{\times} \cong (\mathbb{Z}/8)^{\times} \times (\mathbb{Z}/3)^{\times} \cong \mathbb{Z}/2 \times \mathbb{Z}/2 \times \mathbb{Z}/2$ in which it's easy to see that all elements have order at most $2$ – Cocopuffs Nov 28 '12 at 12:27

$(2a+1)^2=4a^2+4a+1=8\frac{a(a+1)}2+1\equiv \pmod 8\implies c^2\equiv1\pmod 8$ if $(c,8)=1$
Now, $(3b\pm1)^2\equiv 1\pmod 3\implies c^2\equiv1\pmod 3$ if $(c,3)=1$
If $(c,8)=1$ and $(c,3)=1$ i.e., if $(c,24)=1, lcm(3,8)\mid (c^2-1)\implies c^2\equiv1\pmod{24}$
So, $ord_{24}c\mid 2$
But clearly, $ord_{24}c\ne1$ for $c>1\implies ord_{24}c=2$ for $c>1$ and $(c,24)=1$
share|improve this answer
If you look at the numbers mod 6 (the prime divisors of 24 being 2 and 3) you eliminate those equivalent to 0,2,3,4 - so you have left those equivalent to 1 and 5 (i.e. $6n \pm 1$). You could confirm your answer by looking at what happens to the numbers $(6n \pm 1)^2$ when they are taken mod 24.

The privatized Flood Rescue Department commissioned the development of a mobile bridge. It should be used to evacuate flood victims in the most secure and effective way. Mostly from one save point to another.
The elaborate creation process resulted in module like panels called "Bridge Panels" (BP's). These four-sided BP's could be easily plugged into each other to form a stable, reliable and flexible brigde.
The newly developed panels soon evolved into the department's flagship. Future Rescue missions couldn't be imagined without them, since the 55cm²-big tiles can be transformed into organic shapes and therefore provide access to nearly every danger zone.

Now here are the things you'll need to make the bracelet.
Now here are the steps to make the bracelet!!!!
1. Cut a long strand of string and split it in half to make a loop and hook it on a safety pin and then connect the safety pin to a sturdy surface so when you pull the string, it won't loosen (as you can see, I used my carpet).
2. Take string #1 and put in over string #2 and then circle string #1 back around to put it under string #2. Then give string #1 a pull and that should make a knot.
3. Then you do the same thing with string #1 except instead of going over then under, you go under then over. Then give string #1 a pull and that should make a knot.
4. Now its time for my favorite part!! Adding the beads!!! So this is so easy, you just repeat steps 2 and 3 except now you have a bead.
5. Keeping adding beads by repeating steps 2-4 and you'll have a cute bracelet in no time!!!
