Keynote: Motor Vehicle Collisions
On the Highway and Backroads
Nov 12 2021
08:00 - 09:00
Grand Ballroom
Keynote: Motor Vehicle Collisions
At the completion of this session First Responders, EMT's and Paramedics will have a better understanding of how the body can be injured in a collision. We will discuss why the National Highway Traffic Safety Administration (NHTSA) would like for EMS practitioners to stop using the term accidents and instead use the term collisions.
During this session we will discuss the Mechanism of Injuries and Kinetic Energy. This session will include a unique slide show that shows how some injuries may occur from safety devices such as seat belts and air bags. We will discuss and demonstrate rapid forward deceleration and rear-end collisions. We will explain how to provide both BLS & ALS care. We will also explain that some patients that arrive with a C-Collar and Spinal Immobilization may be suffering from serious hidden injuries to their Head and Neck but could also have other serious injuries to their chest, pelvic or vital organs.
You will have a better understanding of the force and energy that is produced during a collision that often causes internal organ damage that is very difficult to recognize without a complete primary and secondary assessment that includes vital signs. At the completion of this class you will better understand the importance of the "Golden Hour".
We will also discuss motor vehicle collisions that happen on the farm and on the back roads of farm country. This session is also designed to show how EMS crews sometimes becomes victims of Ambulance Crashes. We will speak openly about the importance of defensive driving programs, following the rules of the road, speeding, distractions and lack of knowledge about ambulances by some drivers.

Program note
Première: 15 september 1995 - Muziekcentrum Vredenburg, Utrecht by Kees Wieringa
The Latin title of the work means: The same but different. It is a chain of sections (musical objects) that, because these are repeated, aim at a certain independence in relation to the whole. The complement of opposites is, also in this piece, the reflection of the contrast that is anchored in the structure of the tonality. This contrast is about cause and result, tension and relaxation, pairs of functions that in their turn are anchored in the basic layers of the human psyche. This is a perspective that has consequences for the understanding of time and duration and takes away the limits of the concepts of 'beginning' and 'ending', 'before' and 'after'.

A 10-year-old male Rottweiler was evaluated for a 2-month history of recurrent forelimb weakness. Neurologic examination revealed proprioceptive ataxia, tetraparesis and moderate cervical pain. Disk-associated cervical spondylomyelopathy (CSM) with static lesion at C3-4 was diagnosed based on magnetic resonance imaging (MRI). The dog was surgically treated by a ventral slot procedure and distraction-stabilization of the vertebral bodies through insertion of vertebral screws with transverse connective bars. The patient had favorable clinical outcome. Neurologic assessment performed 120 days after surgery showed absence of neurologic defects. Radiographic assessment performed at the same time indicated adequate spinal cord decompression although vertebral fusion was not achieved. To the authors' knowledge, this is the first case of distraction-stabilization with vertebral (pedicle) screws to treat CSM in a dog. The treatment was well tolerated with no complications and excellent outcome and can be a viable option for this condition.

Although all children are at possible risk of being sexually abused, the social exclusion of children with disabilities together with their increased dependency makes them especially vulnerable.
A common misconception is that individuals with disabilities are asexual and are not at risk for sexual abuse and cannot benefit from abuse prevention education. Also in an effort to "protect" the child, many children with disabilities have never received correct information or education about abuse prevention, sexuality and self-protection or personal safety strategies or been provided education on ways to develop and maintain healthy, respectful and supportive relationships.
Furthermore many individuals with disabilities are taught in school, through caregivers and family members to do as they are told, to comply with requests of others, and to control difficult behaviors. They are not taught about boundaries, assertiveness, or the right to say no – especially to authority figures – to painful or other unwanted touches. Compliance training can make the individual vulnerable to abuse or exploitation.
Children with disabilities deserve the right to personal safety as well as to learn strategies to protect themselves, education and training efforts that include sexuality awareness, violence and abuse prevention and assertiveness training help to prevent abuse.
Tulir - Centre for the Prevention and Healing of Child Sexual Abuse and Vidya Sagar - an organization working with disability, invites you to the launch of the Braille version of an awareness flier on personal safety - " Smart Ways To Keep Myself Safe"

A systematic comparison of motion artifact correction techniques for functional near-infrared spectroscopy
Research output: Contribution to journalJournal articleResearchpeer-review
Near-infrared spectroscopy (NIRS) is susceptible to signal artifacts caused by relative motion between NIRS optical fibers and the scalp. These artifacts can be very damaging to the utility of functional NIRS, particularly in challenging subject groups where motion can be unavoidable. A number of approaches to the removal of motion artifacts from NIRS data have been suggested. In this paper we systematically compare the utility of a variety of published NIRS motion correction techniques using a simulated functional activation signal added to 20 real NIRS datasets which contain motion artifacts. Principle component analysis, spline interpolation, wavelet analysis, and Kalman filtering approaches are compared to one another and to standard approaches using the accuracy of the recovered, simulated hemodynamic response function (HRF). Each of the four motion correction techniques we tested yields a significant reduction in the mean-squared error (MSE) and significant increase in the contrast-to-noise ratio (CNR) of the recovered HRF when compared to no correction and compared to a process of rejecting motion-contaminated trials. Spline interpolation produces the largest average reduction in MSE (55%) while wavelet analysis produces the highest average increase in CNR (39%). On the basis of this analysis, we recommend the routine application of motion correction techniques (particularly spline interpolation or wavelet analysis) to minimize the impact of motion artifacts on functional NIRS data.

Time AdvantageTime advantage is created when one of the business processes is faster than the other in achieving the same result. Time advantage is best exemplified with the time to market examples. Time advantage is typically created through careful analysis of all the activities supporting a process and elimination of those that don't add any value to the process, but only add lead time.
Time advantage can create product premiums, increased revenues, longer product life cycles, and intangible differentiator levers (such as brand value or an image of being innovative or agile). It becomes a competitive advantage when the firm develops processes that will enable it to quickly introduce new products in the market and portray the company as a pioneer and when the firm's business strategy leverages such differentiation through a premium brand image to grow market share and increase revenues.
Cost AdvantageCost advantage is created when the superior business process is cheaper to operate than the inferior other. Cost advantage can be created through elimination of waste from the process, but also by optimizing the process within the process constraints. A lot of supply chain processes fall in this category and can provide finite cost advantages when implemented correctly. Inventory planning processes within the supply chain function is a good example in this category.
Or, in a manufacturing industry, cost advantages may arise from better manufacturing process, cheaper inputs, or higher levels of automation that increase efficiency. Reducing set-up change time, reducing the frequency of such changes, and increasing batch sizes are several commonly used methods to reduce per unit manufacturing costs. However, a superior manufacturing process will potentially have a comparable cost structure, but allow for short batch sizes to enable flexible factory schedules.
Every revised iteration of the original business process can potentially improve the existing cost structure and provide a continued superiority afforded by the process. These improvements are necessary to sustain the advantage over time. Cost advantage allows the company to become more profitable or expand its market share.
Efficiency AdvantageEfficiency advantage is created when the superior business processes provide higher throughput. Throughput measures the output of a process per unit time. Sometimes, efficiency may mean asset utilization, such as the utilization of the assembly line in a manufacturing context, blast furnace utilization in steel production, or a jockey's utilization in the warehouse of a retailer. Assets in the context of efficiency can be people, machinery, or technology, anything that it costs to maintain and provides a useful function in the business process. The efficiency advantage can be created by automating, simplifying, or expediting a process. Efficiency advantage normally results in more favorable cost structure and supports a cost-based business strategy.
Think of the flexibility as part of the efficiency advantage. After all, there is no point in efficiently building widgets that no one wants. Therefore, flexibility of a process to change and adapt in response to the changes in the business environment is an advantage that should be built into the process. This flexibility in manufacturing environments typically shows up as set-up change time, while in nonmanufacturing industries, it may be the time required to respond to changing demand.
Quality AdvantageQuality advantage is created when the superior business process creates fewer defects than the inferior one. Quality advantage is generally a result of standardizing, automating, or simplifying a process. In the manufacturing context, a statistical process control (SPC) that allows companies to monitor the health of the process to reduce defects is a good example of this advantage. When compared to the conventional quality control processes that detect the defects after the product has been manufactured, the SPC-based approach prevents production of defective products by monitoring key process parameters. Quality advantage in the nonmanufacturing context relates to the ability of a process to consistently produce the same result (dependability and repeatability), and this definition can be applied to any business function, such as processing customer orders, fulfilling orders from a warehouse, creating replenishment demand, customer service, and so on. Quality advantage can reduce costs by preventing defects or introduce produce differentiators through better quality, such as increased customer satisfaction, customer retention, brand value, product durability, and so on. In all these cases, the quality advantage can support a business strategy by creating a differentiator with a potential value for which the buyer is ready to pay a premium.
Finally, for any process or capability to be able to create a real competitive advantage, the following two conditions must be fulfilled:
1. The value created through the superior process must be valuable enough to the buyer that she is ready to pay a premium for the differentiator created by this process or move her business to the firm to take advantage of this differentiator.
2. The cost of creating the process superiority must be less than the premium generated through the differentiator advantage created by the process.
Unless these two conditions are met, no advantage can be realized. If the cost of creating the differentiation is more than the premium it generates, then the system as a whole becomes less cost competitive, which is not desirable. If the differentiation, whether costor feature-based, is not valuable to buyers, then buyers will not pay any premium for the differentiator, which makes for a wasted investment. Therefore, when firms decide to invest in creating business capabilities, they must spend time to analyze the cost-benefit equation and clearly understand the differentiator created and the value generated through this differentiator from the point of view of the buyer. This is easier said than done. However, good analysis and logical inferences always help.

600 t/h and more is what our 3 metre wide STEINERT KSS combined optical sorting machine can process. Here, limestone of sizes up to 200 mm are analysed and sorted by white level. Only the purest white material passes the valve strip without being diverted. Pieces with even the slightest deviation from the set values are rejected by precisely actuated compressed-air valves. What remains is a very high quality product with low SiO2 content and perfect white levels that can be sold as a high quality product for filler material.
Where the purity of industrial minerals is at stake, we have the correct solution. Our optical sorters are fitted with colour cameras and lasers or near-infrared (NIR) with hyperspectral imaging (HSI) to identify surfaces exactly. The laser helps to detect the surface structure. Thus it is possible to separate crystalline rock such as quartz or fluorspar efficiently from calcium, talcum or other minerals – even when these are the same colour. The HSI camera system offers higher spectral and positional resolution than previous systems, enabling minerals to be detected more accurately. As a result, products such as fluorspar and feldspar, limestone, phosphate and quartz can be created to high levels of quality.
The same technology can be used when it is necessary to extend the working life of a mine. In a deposit with a high strip ratio, extraction is typically selective. This results in large amounts of valuable mineral being lost in order to prevent waste material becoming mixed with the product. Instead of this, however, sorting technology can be used to process the entire extracted deposit and thereby recover a higher proportion of the valuable mineral, which would otherwise be lost. The working life of a deposit can thus be extended.
To ensure that you obtain even higher levels of purity, we employ our high-gradient STEINERT HGS separator offering a flux density of up to 20,000 gauss. This magnetic separator, with double magnetic pole drum, operates with a very thin belt in order to subject the material to the highest possible magnetic flux density. This extremely strong magnetic field enables industrial minerals such as limestone or kaolin to be upgraded further. For the smaller grain sizes of up to 5 mm, the higher degree of breakdown results in higher qualities. Salts can also be upgraded or cleaned by this method, by the separation of clay-containing contaminants.
- Extremely high throughputs (600 t/h)
- Increased product quality
- Optimised degree of whiteness
- Increased working life of mine
- High-gradient magnets for dry processing
High-quality limestone, used in the ceramics industry or as a filler material, must meet high standards. In such cases the SiO2 content must be kept below 0.5%. In the United Arab Emirates, two STEINERT KSS FL colour sorting units, each with 3 metres working width, are in use for this purpose. Overall the machines process over 500 tonnes of limestone per hour.
In southern Africa, calcium carbonate is obtained from calcite and dolomite. A STEINERT KSS FLNR sorting machine equipped with colour detection and NIR is used here to sort off amphibolite and other waste rock. The machine handles various grain spectra. With the coarsest fraction, 40 to 80 mm, throughput rates can be achieved of up to 100 t/h.
Wollastonite with STEINERT HGS
With its fibrous crystals and high melting point, wollastonite is used in many applications. Because of the high melting point, wollastonite is often a replacement for asbestos fibres. A further area of application is the ceramics industry, in which it is used to improve the mechanical properties of white ceramics goods. For this, the demands on purity are extremely high. In China seven STEINERT HGS high gradient magnetic separators are used to produce high-purity wollastonite.


of this, we tried to optimize where we cut the tape so we could splice in power and data without having to solder it directly to the tape itself. We spliced by simply soldering wire together and wrapping the joints in electrical tape.
2. Soldering the Banks
Solder station
Based on our design, we knew each strip would be about 10 5/8″ apart, so we cut and stripped 12″ lengths of three conductor wire to use as jumpers to connect strips of tape in series into banks. Then we soldered the strips together–careful to pay attention to the directionality of the tape–into completed banks.
3. Testing
We found out the hard way that you can almost instantly destroy pixels or even entire strips of tape if you have a power short. A power short really means the positive and negative sides of your DC power are connected somewhere with very low or no resistance. As the resistance approaches zero (a complete short) your current grows towards infinity, or as much as your power supply can push. This surge in power will likely fry an LED or two. You can test for a short but checking resistance (Ω) anywhere on your tape across the positive and negative sides of your power lines.
Tip We discovered that there can be some continuity in the tape across those lines, but we considered anything less than 200 Ω to be a short. We saw as little as 300 Ω of resistance in well-connected tape.
We also double-checked that we had the connections right: data to data, positive to positive, and negative to negative. At some points where you're injecting power, your colors may not line up and things can get a little tricky, so it's worth double-checking.
Finally, we plugged the tape in and powered it up before gluing it to the wall. We would simply wire the input side into the Plink it would be connected to, and ensure we could control the bank from E.L.M. and that everything was working as expected.
Our first test brought a little tear to our eye...
Our first test almost brought us to tears… 😂
4. Gluing the Bank to the Wall
Although the tape does come with a 3M adhesive strip, we found it didn't stick well enough to the painted wall we were attaching it to. We found Gorilla glue gel worked the best.
We used a laser level to mark the vertical line for our strip, laid down some glue, and pressed the strip onto the wall.
5. Connecting Control and Injecting Power
We soldered leads onto the tape before gluing it to the wall since it's much easier to solder on a workbench than once the tape is glued to the wall. We made sure the leads for control and power were plenty long enough, so we simply had to cut, strip and connect them to the Plink or terminal block we set up for that bank.
6. Testing and Mapping
Finally, once the tape was glued on with control and power wired in we did a last test to make sure we had proper control of the bank, including the direction of each strip and full RGB control. We also set the bank to full white to ensure there were no visible voltage drops and if required we injected additional power to maintain a perfect white.
Tip For some reason that I never really dug into, the pixels weren't always addressed completely as expected. Often times most of them would be right in order, but a few pixels would jump to the end of the universe. When you're testing, make sure you address all pixels in the universe if some are missing. You might have to sort of reverse engineer their address to finalize your mapping.
Progress! Part of our completed wall during the install:
Progress! Part of the wall is complete.
You're all set now to start playing media and lighting up those beautiful pixels! I'll talk more about configuration and control in part 3.

What do you want from a Metaphor: #7
The image of a metaphor is strengthened if
7. it is somewhat common.
You want to reinforce the notion that love is ubiquitous and that your relationship thrives in the every day. Marriage, after all is an every day activity. The metaphor you choose to illustrate your love in your wedding ceremony should be frequently encountered.
If something is too exotic in your life, then your chances of encountering it are slimmer. You loose the reinforcement that common activities offer. So using an image that involves the life-cycle of a camel if you live in Rhode Island, even if it can be made gloriously beautiful, is not going to provide the daily reinforcement that the tides of the sea or the changing of the seasons might.
Tip: Choose a metaphor to describe your relationship that has value and frequency in your life. Then it can be something more than poetic beauty, it can be a marital aid.

File Tests in Perl
In this article, you will learn how to find out useful information about files in Perl. It is excerpted from chapter 11 of the book Learning Perl, Fourth Edition, written by Randal L. Schwartz, Tom Phoenix and brian d foy (O'Reilly; ISBN: _PHONE_). Copyright © 2006 O'Reilly Media, Inc. All rights reserved. Used with permission from the publisher. Available from booksellers or direct from O'Reilly Media.
Earlier, we showed how to open a filehandle for output. Normally, that will create a new file, wiping out any existing file with the same name. Perhaps you want to check that there isn't a file by that name. Perhaps you need to know how old a given file is. Or perhaps you want to go through a list of files to find which ones are larger than a certain number of bytes and not accessed for a certain amount of time. Perl has a complete set of tests you can use to find information about files.
File Test Operators
Before we start a program that creates a new file, let's make sure the file doesn't already exist so that we don't accidentally overwrite a vital spreadsheet data file or that important birthday calendar. For this, we use the –e file test, testing a filename for existence:
 die "Oops! A file called '$filename' already exists.n"
 if -e $filename;
We didn't include $! in this die message since we're not reporting that the system refused a request in this case. Here's an example of checking if a file is being kept up to date. In this case, we're testing an already opened filehandle instead of a string file name. Let's say that our program's configuration file should be updated every week or two. (Maybe it's checking for computer viruses.) If the file hasn't been modified in the past 28 days, then something is wrong:
 warn "Config file is looking pretty old!n "
 if -M CONFIG > 28;
The third example is more complex. Let's say disk space is filling up; rather than buy more disks, we've decided to move any large, useless files to the backup tapes. So let's go through our list of files* to see which of them are larger than 100 KB. But even if a file is large, we shouldn't move it to the backup tapes unless it hasn't been accessed in the last 90 days (so we know it's not used too often):†
 my _USER_; # The ones we want to put on backup tapes
 foreach my $filename (_USER_) {
 push _USER_, $filename
This is the first time that you've seen it, so maybe you noticed that the control vari able of the foreach loop is a my variable. That declares it to have the scope of the loop, so this example should work under use strict. Without the my keyword, this would be using the global $filename.
The file tests look like a hyphen and a letter, which is the name of the test, followed by a filename or a filehandle to test. Many of them return a true/false value, but several give something more interesting. See Table 11-1 for the complete list and read the following discussion to learn more about the special cases.
Table 11-1. File tests and their meanings
File test Meaning
-O File or directory is owned by this real user
-e File or directory name exists
-f Entry is a plain file
-d Entry is a directory
-l Entry is a symbolic link
-S Entry is a socket
File Test Operators
Table 11-1. File tests and their meanings (continued)
File test Meaning
p Entry is a named pipe (a "fifo")
-u File or directory is setuid
-g File or directory is setgid
-k File or directory has the sticky bit set
-t The filehandle is a TTY (as reported by the isatty() system function; filenames can't be tested by this test)
-T File looks like a "text" file
-B File looks like a "binary" file
-M Modification age (measured in days)
-A Access age (measured in days)
-C Inode-modification age (measured in days)
The tests -r, -w, -x, and -o tell if the given attribute is true for the effective user or group ID,* which essentially refers to the person who is in charge of running the program.† These tests look at the permission bits on the file to see what is permitted. If your system uses Access Control Lists (ACLs), the tests will use those as well. These tests generally tell if the system would try to permit something, but it doesn't mean that it really would be possible. For example, -w may be true for a file on a CD-ROM, though you can't write to it, or -x may be true on an empty file, which can't truly be executed.
The -s test does return true if the file is non-empty, but it's a special kind of true. It's the length of the file, measured in bytes, which evaluates as true for a nonzero number.
A Unix filesystem‡ has seven types of items, represented by the seven file tests -f, -d, -l, -S, -p, -b, and -c. Any item should be one of those. If you have a symbolic link pointing to a file, that will report true for -f and -l. So if you want to know whether something is a symbolic link, you should generally test that first. (You'll learn more about symbolic links in Chapter 12.)
The age tests, -M, -A, and -C (yes, they're uppercase) return the number of days since the file was last modified, accessed, or had its inode changed.* (The inode contains all of the information about the file except for its contents. See the stat system call manpage or a good book on Unix internals for details.) This age value is a full floating-point number, so you might get a value of 2.00001 if a file were modified two days and one second ago. These "days" aren't necessarily the same as a human would count. For example, if it's 1:30 A.M. when you check a file modified at about an hour before midnight, the value of -M for this file would be around 0.1, even though it was modified "yesterday."
When checking the age of a file, you might get a negative value like -1.2, which means that the file's last access timestamp is set at about thirty hours in the future. The zero point on this timescale is the moment your program started running,† so that value might mean a long-running program was looking at a file that had just been accessed. Or a timestamp could be set (accidentally or intentionally) to a time in the future.
The tests -T and -B determine if a file is text or binary. But people who know a lot about filesystems know there's no bit (at least in Unix-like operating systems) to indicate that a file is a binary or text file, so how can Perl tell? The answer is that Perl cheats: it opens the file, looks at the first few thousand bytes, and makes an educated guess. If it sees a lot of null bytes, unusual control characters, and bytes with the high bit set, then that looks like a binary file. If there's not much weird stuff, then it looks like text. It sometimes guesses wrong. If a text file has a lot of Swedish or French words (which may have characters represented with the high bit set, as some ISO-8859-something variant, or perhaps even a Unicode version), it may fool Perl into declaring it binary. So it's not perfect, but if you need to separate your source code from compiled files, or HTML files from PNGs, these tests should do the trick.
You'd think that -T and -B would always disagree since a text file isn't a binary and vice versa, but there are two special cases where they're in complete agreement. If the file doesn't exist, or can't be read, both are false since it's neither a text file nor a binary. Alternatively, if the file is empty, it's an empty text file and an empty binary file at the same time, so they're both true.
The -t file test returns true if the given filehandle is a TTY—if it's interactive because it's not a simple file or pipe. When -t STDIN returns true, it generally means that you can interactively ask the user questions. If it's false, your program is probably getting input from a file or pipe, rather than a keyboard.
{mospagebreak title=File Test Operators}
Don't worry if you don't know what some of the other file tests mean—if you've never heard of them, you won't be needing them. But if you're curious, get a good book about programming for Unix. (On non-Unix systems, these tests all try to give results analogous to what they do on Unix, or give undef for an unavailable feature. Usually, you'll be able to guess what they'll do.)
If you omit the filename or filehandle parameter to a file test (that is, if you have -r or just -s ), the default operand is the file named in $_.* So, to test a list of filenames to see which ones are readable, you type the following:
 foreach (_USER_

Black history month
This Week in History
West Palm Beach
World War II
One of the more popular landmarks in Palm Beach County is the Little Red Schoolhouse, the first in southeast Florida (1886), which was restored and sits in Phipps Ocean Park in Palm Beach.
But Martin County has its own landmark: the New Monrovia One-Room Schoolhouse, believed to be the only remaining one on the Treasure Coast.
Built around 1930, the 25-by-30 wood-frame structure was one of the first schools built in Martin County to educate black children.
On March 9, county officials, former students and historians cut the ribbon on the newly-restored structure.
The schoolhouse is in what is now Port Salerno. Plats called it Salerno Colored School, but students remembered it as Mrs. Williams' School, for Costella Hannibal Williams, who moved to the area in 1929 and taught at the school until around 1960.
Warmed by a pot-belly stove, their way lit by kerosene lamps, black children looked to Williams as a mother figure.
Those children include retired Indian River Community College administrator David "Doc" Anderson, the first black elected to the Martin County School Board. He served 32 years on the panel, including stints as its chairman.
Anderson was a student in first through fourth grades, 1946 to 1950.
He said the four grades shared the one room, and one teacher: Williams.
"She was something else. She was quite a person. I don't know how she did it," Anderson said.
Williams — described as the "Matriarch of New Monrovia" in the 2000 Palm Beach Post book Our Century — retired from Martin County Schools in 1975. According to the Stuart News, she died at 97 in Palm City on April 19, 2003.
The schoolhouse eventually closed and the county used the building as a community center, then closed that in 1998 after building a civic center next door that bore Williams' name.
The schoolhouse fell into disrepair and was damaged by hurricanes Frances and Jeanne in 2004.
Martin County spent $115,000 to restore the schoolhouse; it received a roof, floor and ceiling, windows and doors, and a fresh coat of paint.
Three of the original walls were saved.
Inside, green chalkboards hang from the original locations on the wall, and replicas of the students' original wooden desks, built by South Fork High School carpentry students, line the room.
And there's even a potbelly stove.
Visitors view the interior of the renovated Monrovia One-Room Schoolhouse during its re-dedication March 9. The building, believed to be Martin County's last surviving one-room schoolhouse, was one of the first schools built in the county for black children. (Photo courtesy Martin County)

Valentine's Day isn't the only thing around here that's red. Palm Beach's "Little Red Schoolhouse," the only school in all of southeast Florida when it opened March 1, 1886, reopened this month after being closed for nearly a year.
Once again, the Preservation Foundation of Palm Beach will host its "living history" program, which takes fourth-graders back in time for a mini-day in a one-room school of the 1890s.
The schoolhouse, in Phipps Ocean Park, was closed during a yearlong soil-remediation project in the park. The Foundation took advantage of the down time to renovate and update it.
When it opened, it was the only schoolhouse in what was then Dade County, which was a swath of scattered settlements stretching north to Stuart and covering an area the size of Massachusetts.
A county grant of $200 paid for lumber for the 22-by-40-foot building. Laborers donated time.
The Ladies Aid Society raised another $200 from the sale of embroidery and quilts to pay for furniture and supplies.
The first class had seven students ranging from 7 to 17 years old.
The teacher was Hattie Gale, from Kansas. She was all of 16, younger than some of her charges.
She was the daughter of the Rev. Elbridge Gale, a minister, educator and professor of horticulture, who retired to the area from Kansas in November 1884 and became one of the first to build a cabin on the west side of Lake Worth (the Intracoastal Waterway).
Hattie, who arrived in 1885, taught for only three months before the area hired a teacher for $100.
In 1901, the schoolhouse closed and a boat ferried the children to the new four-room school at Clematis Street and Poinsettia Avenue, now Dixie Highway, in West Palm Beach.
The original building was moved to Casa Bendita, the Palm Beach estate of John Phipps. It sat there for four decades, where it was used as a potting shed.
In 1960, shortly before Casa Bendita was razed, the schoolhouse was dismantled and moved to Phipps Ocean Park. In 1990, the Preservation Foundation restored the building to look like a one-room schoolhouse.
The building is closed to the public, except for the "living history" program.

This is Black History Month. More than one person over the years has wished for a time when we don't need a special day to single out one ethnic group's accomplishments. Until then, this column will endeavor to point out the long struggle of all minority groups — and to honor that struggle's many heroes.
One of our most unsung heroes might well be Charles H. Stebbins, Jr. Here's more from columns in 2004 and 2007:
His legacy was continued partly through the accomplishments of his niece, Freddie Lee Stebbins Jefferson, an educator, community leader and Palm Beach Post columnist who died at 71 in October 2007. And through Freddie's husband, retired educator and activist James Julius "Jeff " Jefferson, who died at 80 in 2011.
Charles Stebbins wanted to be paid the same as white teachers. But he never benefited from the victory he helped achieve. Long since fired from his teaching job, he was waiting tables in New York the day in 1941 when a federal judge's ruling set a stunning precedent. It was a step toward the landmark 1954 Brown v. Board of Education decision.
White teachers with five years of experience had received a $25 raise. Furious black counterparts, who got no raise, founded the Palm Beach County Teachers Association and about 85 percent of the county's 115 black teachers joined.
The group brought in Thurgood Marshall, later the Supreme Court's first black justice. They needed a name to put on the lawsuit against the county school board. Charles Stebbins volunteered.
The Arcadia native taught social studies at West Palm Beach's Industrial High School until he was fired. A school board official offered him $500 and his job back to drop the case. His wife was ill — she would die in a year and a half — but he declined.
"He was blackballed throughout the state," Freddie Jefferson said in 1999. "He was the troublemaker." Also, the black union failed to honor a promise to pay him a year's salary if he was fired.
Stebbins moved to New York, then served in the Navy, where he filed two discrimination suits. He worked 32 years for the Federal Home Loan Bank Board, where he sued for promotions, but failed. He never returned to education, and died in 1991.

Thanksgiving and football may mean watching the NFL on TV today, but Palm Beach County fans of a certain age will recall when THE Thanksgiving game was Palm Beach High vs. Lake Worth — a long-time rivalry played on the eve of Thanksgiving. The annual holiday game began in 1928 and continued through the 1960s, when the Forest Hill Falcons stood in for the Lake Worth Trojans.
The 1964 game has been described as the one of the most publicized football games in Palm Beach County history. Both teams — the Palm Beach Wildcats and the Forest Hill Falcons — were unbeaten. The preview story in The Palm Beach Post began, "Tonight's the night when the hopes and dreams of an unbeaten-untied football season are wrapped up in 48 violent minutes of combat."
The Palm Beach High football team as pictured in the Nov. 25, 1964 game preview story in The Palm Beach Post.
The Wildcats won that 1964 game 25-6.
The 1946 game between Palm Beach and Lake Worth drew what The Palm Beach Post called "the largest crowd in the history of Palm Beach County football," with estimates ranging up to 10,000.
The cover art on the program from the 1946 game was by Lon Keller, an artist from Pennsylvania whose work was featured on high school and college football game-day programs from 1938-70.

Neiker-Tecnalia estimates the growth of vines using an innovative system that measures their infrared radiation emission
The Basque Institute of Agricultural Research and Development Neiker Tecnalia has tested the effectiveness of an innovative system to estimate vegetative growth in vines by measuring the infrared radiation emission of the plants. The method is known as the Normalized Difference Vegetation Index (NDVT) and estimates the vegetative growth of plants by measuring the solar radiation that plants reflect in the red and near-infrared band of the electromagnetic spectrum.
In order to provide farmers and anyone else involved in managing agricultural ecosystems with a tool enabling them to assess the impact of their farming practices on the health of their crops and soils, the Basque Institute for Agricultural Research and Development NEIKER-Tecnalia has created its new TSEAs or 'Agricultural Ecosystem Health Cards'. These handbooks are an improved version of the cards created in the 1980s by the United States Department of Agriculture. The R&D centre is holding various meetings to make these handbooks known to various groups (growers, technicians, scientists and the administration) linked to the agricultural sector and who will receive them free of charge.

iPad/Digital Texts Pilot: Phase II
RCDS will continue to pilot iPads and digital texts during the 2012-2013 academic year. Preliminary findings and new questions that emerged from the 2011-2012 phase of the pilot suggested that another year of exploration is warranted before making recommendations regarding the use of iPads and digital texts at RCDS.
What are the goals of Phase II?
The guiding questions for Phase II are as follows:
- How can iPads be used in Lower School classrooms to differentiate learning, support academic choice, and support the curriculum?
- What will be the role of iPads (or other e-readers) in our K-12 curriculum? In what ways is our intended use of iPads different from our intended use of laptops in the classroom?
- How useful are iPads with e-texts? Are they workable for note taking, SMARTBoard use, etc? Are they useful in flipped classroom situations?
- Are e-texts a viable option for students? For whom would e-texts be an appropriate choice?
- What is the relative ease of e-text use across the board: reading, note taking and sharing, searching, testing/evaluation, grading/commenting, etc.? Will students prefer e-texts or printed texts after exposure?
- What are the relative costs of digital texts?
- How will learning change with digital texts? Will be see an improvement or not?
- How will teaching change with digital texts? How will interactions with students change?
- What technical support will be required for this additional layer? Will we have bandwidth issues for internet access? Does our current in-class technology support the integration of iPads?
What will Phase II entail?
All courses, including every class in the Lower School, are eligible to participate in the pilot in one of three ways:
- iPads only (to explore apps, content creation, internet use, etc.)
- E-texts on laptops only
- E-texts on iPads and laptops
There is no set timeframe for participation. Teachers may participate anywhere from one day up to several weeks at a time. Feedback will be gathered from every class that participates.
If you have any questions about either Phase I or Phase II of RCDS's Digital Text Pilot, please contact Meredith deChabert, Assistant Head of School, at _PHONE_.

An honor system administered by students is among William & Mary's oldest and most important traditions. At its core, the honor system requires that students conduct themselves honestly in all matters related to student life.
At the Law School, the honor system is administered by the Honor Council, composed of students from each class.
The existence of the honor system, and the student body's commitment to it, permits a community of trust and an atmosphere of freedom at the Law School. For example, examinations are not proctored, students may take them anywhere in the building, and many exams are self-scheduled. Students are permitted to use their laptops for exams and are trusted to follow the rules governing their use.

Role of Environment in European Conquestby Rit Nosotro
What part did environment play in allowing Eurasians to conquer the native peoples of Africa, Australia, or the Americas? (hint: Guns, Germs and Steel by Jared Diamond)
Throughout history we witness the rise and fall of many civilizations. Many nations exist in different forms now than they did only fifty years ago. The changes that the civilizations underwent thousands of years ago provide the foundations for the current world that we see today. But what caused specific civilizations to conquer other civilizations? We see the strong influence of the Eurasian civilization in all our existing cultures today. Many factors added to this, and the environment in which the Eurasian culture dwelled probably had a very influential role in allowing them to conquer the other civilizations of their time. Their environment influenced the lifestyle of these people and directly affected the resources that they had available to them in their pursuits of war and peace.
Firstly, we must determine what constitutes an environment, and what aspects of life an environment will affect. The environment of a culture describes the weather, geography, and local natural resources. Throughout history, thriving civilizations have tended to spring up near a river or other body of water. People need water to survive, not only for drinking but for watering their crops and livestock as well. When Babel was destroyed and the people divided by language, they traveled and found new areas to settle. According to the Xenophile Historian website, "The ideal place for a civilization to develop is a place where life is not an everyday struggle, but it requires some effort to make it comfortable." In particularly harsh lands, such as the dry, hot desserts that cover much of Africa and Australia, the inhabitants must fight daily simply to maintain survival. Historically, they lacked the ability to settle down in one area for too extended a time because the lack of water would cause the natural resources to deplete. Even if they could stay permanently in one place, they still had to concentrate on fulfilling their basic survival needs. These societies had no time to develop a system of writing or complex government. In contrast, in areas like the jungles of South America, food literally just falls from the air. The people have no need to create any kind of lasting agricultural plan, such as farming or shepherding, because they have all the sustenance they need readily available to them already. This sort of bountiful environment hinders the development of a thriving, settled civilization just as much as the harshness of the desert.
However, on much of the Eurasian continent, particularly in the Fertile Crescent, semi-permanent civilizations flourished. They had to develop an agricultural system of plants and animal herds because the land did not naturally produce them, but would support them if nurtured. This gave the civilizations a sort of permanence. "Pure hunting/gathering is about 100 times less efficient than herding; it only feeds an average of one person per ten square miles." (Xenophile Historian) So these societies that developed farming and herding also had a larger number of people per square mile. This provided solidity to a society in many different ways. First of all, with a larger amount of people, disease is less likely to destroy the entire society. Secondly, with so many people, they could divide the labor among them in a way that allowed different people to specialize in different occupations. Instead of everyone having to know a little about everything, you could have people who knew a lot about one thing. Jared Diamond references this concept as it relates to the Polynesian Islands, "In general, the larger the size and the higher the density, the more complex and specialized were the technology and organization." If the people had specializations, not only did they develop skills in certain areas, but it also gave time for someone to pursue writing and the arts as their specialization. So when this society of people with special skills invaded other societies, they had a big advantage. The civilizations of Eurasia produced people who had specialized in politics, weaponry, or war. This specialization allowed the society to progress exponentially in their development of these technologies. These societies had organized governments system, which oversaw militaries that employed cutting-edge weapon technology. As a result of these advances in their society, they had preparation and many advantages over the societies they attacked.
Another variable factors into all of this and in fact provides an in depth and overarching explanation for it all. Psalm 97:1 says, "The LORD reigns; Let the earth rejoice; Let the multitude of isles be glad!" Throughout all the ages, the one thing that remains the same is God's sovereignty. He has a divine and sovereign plan and controls all of the events of the world. As a result, nothing happens simply by chance. Each of these civilizations and its inhabitants dwelt in precisely where God ordained them in order to accomplish their part in His supreme plan.
1. How do the rises and falls of historical civilizations affect us today?
2. What are non-ideal geographical areas for civilizations and why do both extremes have big disadvantages?
3. What is the ideal place for a civilization to develop and why?
4. In the end, does any of this completely explain the rise and fall of civilizations? If so, how? If not, where can we find a complete explanation?

Characterization of soil microbes associated with a grazing-tolerant grass species,Stipa breviflora, in the Inner Mongolian desert steppe
Authors: Chen, Lingling; Saixi, Yala; Yi, Ru; Baoyin, Taogetao
Although soil microbial communities are central in ecosystem functioning, we know little of their characterization for those associated with grazing-tolerant host plant species in grassland ecosystems in response to grazing. In this study, we used a high-throughput sequencing approach to characterize soil microbes from the rhizosphere and bulk soil of grazing-tolerant grass species,Stipa breviflora, in the Inner Mongolian desert steppe. We found that response mechanisms of soil bacteria distinct from fungal communities, and variance also occur between the rhizosphere and bulk soil communities under long-term grazing. Soil fungal communities and the co-occurrence networks inS. breviflorarhizosphere were more sensitive to long-term grazing than bacteria. We reveal that rhizosphere effects and soil water content were the main drivers of the changes in fungal communities and their co-occurrence networks. Moreover, the dominant bacterial phyla Bacteroidetes and Proteobacteria and fungal phyla Ascomycota and Glomeromycota might participate in regulating processes ofS. breviflora'sresponse to grazing. Overall, these findings give new snapshots of mechanisms of how grazing affects soil microbial communities, in an attempt to contribute to a clearer understanding of grazing-tolerant mechanism ofS. breviflora.
A modified velocity updating algorithm for a strapdown INS
Authors: Ben, Yueyang; Gao, Qianqian; Li, Qian; Liu, Xingyu
Velocity updating typically involves integration of the transformed specific force and gravity Coriolis velocity increments. If the angular rate and specific force vectors maintain fixed directions relative to a frame, updating the velocity in that frame will be straightforward. In practice, the coning angular rate and sculling specific force vectors cause a calculation error in velocity updating on the navigation frame. Thus, the development of sculling compensation algorithms for the reduction of the sculling error is necessary. In this study, a new method for the propagation of vehicle velocity is proposed. This method utilizes an auxiliary frame that slews along with the angular rate and specific force vectors, which remain fixed in the auxiliary frame. This transforms and integrates the specific force vector in this auxiliary frame such that it is error-free. Additionally, the updated velocity can be obtained by translating the above results to the navigation frame, thereby avoiding the need for sculling correction. The validity of this proposed method under the influence of a typical slewing motion was established experimentally, suggesting that it provides an efficient and accurate velocity propagation method that can be employed in aerospace applications.

How to Design a Barbecue Area
Backyard barbecues have come a long way from the basic, charcoal-burning grill rolled out from the garden shed for an occasional summer cookout. Homeowners living in moderate climates often use their grills year-round, turning barbecue areas into permanent outdoor kitchens.
Use weatherproof materials on outdoor cabinetry.
Elaborate gas grills are surrounded by built-in cabinets, counter space, sinks, extra storage, and often include other appliances such as small refrigerators or wine cooling cabinets. Since the grill itself is the main attraction, the surrounding area should support the function while making sense with the design and form of the grill. A well-designed barbecue area first should factor in safety, followed by function, and end with an aesthetically pleasing outdoor living space, no matter what type of grill is at the center.
 Measure the available space where you plan to build your barbecue area.
 1. Measure the overall available space on your patio, deck or yard where you plan to build your barbecue area. Draw a rough sketch of where the grill will be located and fill in the surrounding space with the items you want to include. Use the sketch as a guide to take approximate measurements of the grill space, storage space, food prep space and dining space. Fill in each measurement in the appropriate location of the sketch. Refer back to your barbecue area floor plan as needed while you buy the items and materials needed.
 2. Space and fuel are important factors for choosing a grill type.
 3. Think about the type of barbecue grill you would like, and what will fit in the available space. Consider the type of fuel needed to cook. Adjust the placement of the grill to accommodate gas or electricity running from the house if you are planning a permanent outdoor kitchen. Include storage -- at least six or seven feet away from the heat source -- for an extra propane tank or charcoal for portable grills. Choose a well-ventilated area for gas or charcoal grills. Use an electric grill on a balcony, terrace or screened-in porch.
 4. Stone and brick are heat resistant and fireproof.
 5. Consider safe flooring materials for the cooking area. Choose heat-resistant materials such as cement, brick, stone or ceramic tile. Use a grill mat or pad when cooking on a wood deck or uneven surface.
 6. Install outdoor cabinets built with marine-grade polymers that can withstand direct exposure to UV light, heat and moisture. Protect wood cabinetry with weatherproof materials such as backerboard, which provides a surface to which brick or stone masonry can adhere. Use a composite base under wood-framed cabinetry to prevent mildew and rot.
 7. Outdoor appliances provide convenient kitchen ammenities.
 8. Add the outdoor appliances, such as compact refrigerators, ice bins and coolers, included in your barbecue area floor plan. Include extra features such as a sink and fully stocked outdoor bar or beverage center if space and budget allows. Include adequate storage drawers, bins and shelves for cooking and eating utensils, glassware, cookware and tableware.
 9. Cover your barbecue area with a roof.
 10. Build some type of roof structure over your cooking and dining areas to shelter from direct sun and rain. Install lighting for more convenient after-dark entertaining. Include a dining table and plenty of seating options.
If your budget is tight, build your barbecue area in stages, as your budget allows. If you rent a home, you can build or buy a portable outdoor kitchen and take it with you when you move. Your barbecue area design should be consistent with the design of your home and your skill level as a DIY craftsman. Enhance this outdoor living space with potted plants, candle lanterns and fabric upholstery on seating cushions that ties in with the decor inside your home.
Always read the owner's manual and especially the safety guidelines before using a new grill.
Always light a gas grill with the lid open. Check all connections, pipes, hoses and the tank for damage or leaks before using a grill that has been stored or unused for a few months.
Turn off the gas first, then the controls on a gas grill to burn any gas remaining in the pipe.
Two 20-pound propane tanks are the legal limit for oneor two-family residential properties.

You can see some of the world's most endangered species on Sri Lanka active holidays
If you're enjoying Sri Lanka active holidays, then you'll come across amazing scenes of wildlife.
The island nation has built a sterling reputation for its amazing natural scenery and wildlife.
Species such as elephants, leopards and sloth bears can be seen in Sri Lanka in all their glory.
Because of the strong Buddhist traditions that prevail in many parts of the country, it has enjoyed a culture of conservation stretching back more than two millennia.
Today, the beautiful South East Asian nation boasts no less than nine national parks and seven bird sanctuaries, which offer protected habitats to many wonderful species and give tourists unique opportunities to see them in the wild.
As Sri Lanka's tourism board points out, 43 of the world's endangered species can be seen in the country's national parks.
"Sri Lanka though small in size, is one of the few places on earth where the world's largest land and sea mammals can be seen in a day.
"Home to the inimitable Asian elephant, Sri Lanka's southern ocean waters are the playground to the giants of the sea - the docile blue whales."

Special Traits
 - Amend Time. As a bonus action, the savant alters the strands of time surrounding a creature it can see within 30 feet. If the target is friendly, the target has advantage on its next weapon attack roll. If the target is hostile, the target must succeed on a DC 15 Charisma saving throw or have disadvantage on its next weapon attack roll.
 - Magic Resistance. The savant has advantage on saving throws against spells and other magical effects.
 - Past and Future, Present. A savant is always accompanied by its past and future selves. They occupy the savant's same space seconds before and after the savant and can't be targeted separately. They provide the savant with the following benefits. The savant can concentrate on two spells simultaneously. If it casts a third spell that requires concentration, the savant loses concentration on the oldest spell. If the savant is concentrating on two spells and loses concentration because of taking damage, it loses concentration on the oldest spell. When a creature targets the savant with an attack, roll a d6. On a 1 through 4, the attack hits one of the savant's future or past selves, halving the damage the savant takes. On a 5 or 6, the attack hits the savant, and it takes damage as normal. The savant is still the target of the attack and is subject to effects that trigger when a creature is hit or damaged.
 - Spellcasting. The savant is a 9th-level spellcaster. Its spellcasting ability is Intelligence (spell save DC 15, +8 to hit with spell attacks). The savant has the following wizard spells prepared:
 - Multiattack. The eonic savant makes three melee attacks.
 - Time Warping Staff. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 6 (1d6 + 3) bludgeoning damage plus 7 (2d6) force damage.
A jagged blue scar of magical energy forms in the air, and a blue-robed figure steps out a moment later.
As it moves, echoes of it appear to move a split second before and after it. The creature focuses its attention and the echoes solidify around it, one wielding the creature's staff, the other a spell.
The eonic savant is an eonic drifter who learned to fully harness the power of its many future and past selves.
Still Adrift in Time. Through their mastery of time, they were able to spare their bodies many of the same ravages of time experienced by their brethren. In spite of this mastery, they are no closer to finding the cure or the correct time stream for their dying ancient civilization.
Calm and Assured. Unlike their kin, eonic savants hold the energy to jump through time within their bodies, freeing them from a reliance on their people's crystal belts and the paranoia its loss brings. Savants devote themselves to studying the rivers of time and helping their kin, who are barely surviving time's flood. They are certain with enough study and enough of their kin by their sides, they can discover the way to a cure and the way home.

At some point in the 1970s, Lego included the following letter to parents in its sets:
The text reads:
The urge to create is equally strong in all children. Boys and girls.
It's imagination that counts. Not skill. You build whatever comes into your head, the way you want it. A bed or a truck. A dolls house or a spaceship.
A lot of boys like dolls houses. They're more human than spaceships. A lot of girls prefer spaceships. They're more exciting than dolls houses.
The most important thing is to the put the right material in the their hands and let them create whatever appeals to them.
The letter seems like the sort of thing that might be fake, but Robbie Gonzalez of io9 presents the case for its authenticity.
In our home, Lego currently rules the roost…the kids (a boy and a girl) spend more time building with Lego than doing anything else. This weekend, they worked together to build a beach scene, with a house, pool, lifeguard station, car, pond (for skimboarding), and surfers. Dollhouse stuff basically. Then they raced around the house with Lego spaceships and race cars. Nailed it, 1970s Lego.
Update: QZ confirms, the letter is genuine.


The Lawful Good and Chaotic Evil
If you have been on social media for any length of time, you likely have seen a meme that looks something like this:
And half of them seem to use Game of Thrones character for whatever reason. (
Long before these charts became "meme worthy", players of RPGs like Dungeons and Dragons were familiar with building characters in a similar way, aligning their characters along a "moral and ethical axis". A full (very handy) breakdown is available on TV Tropes, but it can basically be broken down into:
Now, these breakdowns don't always work for fiction writers (as TV Tropes very smartly says, "remember that the vast majority of characters in fiction are not tabletop game characters, and therefore lack a canonical interpretation of alignment") more and more I have found it helpful to think of characters who fit a "vague alignment", both when it comes to writing and editing. Why? For the same reason the charts came into fashion for role playing games, I imagine. Because it is a handy way to develop just who your character is.
Personally, looking into alignments arose as part of writing my Broken Line Series. With each book following a different main character (and yet interlocking with each of the others) it became very important to develop each character as their own person, otherwise everything slowly began to get a little too wishy-washy with an ever-growing cast of characters. Thinking of a character in terms of a designation (along with plenty of other character building of course) it can be simpler to think just how they would react when thrown into a tough spot.
So, if dealing with a number of characters (or simply needing to flesh out a single character further) consider their alignments:
 - Lawful Good: Simply put, the Lawful Good believes that, well, the law is good. Being a good person (which they strongly wish to be) requires upholding the law. This character believes in truth, justice, and other ideals seen as virtuous, but such strong convictions may also prove their undoing (see poor Ned Stark up there). They are so committed to their ideals, they may struggle to uphold them even to their own (or other's) detriment.
 - Neutral Good: For the Neutral Good, doing the right thing is very important, but the right thing doesn't always mean the lawful thing. Following their personal morals, doing good is more important than upholding the law, but they also don't see law as a bad thing. If they are able to do good by playing by the rules, they will. If they have to break a few laws to save someone, however, they don't find themselves in an ethical quandary. As TV Tropes puts it, "Just think 'basically nice person' and you've probably got it."
 - Chaotic Good: Home to the rebels and free spirits, the Chaotic Good want to help people and do good, but they tend to believe that things like order and discipline get in the way. For all the Whovians out there, my personal favorite picture I've seen for Chaotic Good is The Doctor. The man always wants what is best for everyone, but isn't about to let silly things like laws (even generally good ones) get in the way of achieving good.
 - Lawful Neutral: The Lawful Neutral is "the rule-abiding sort". Good and evil are all well and good, but not something that keeps them up at night. Law and Order (not the show) are what drives the Lawful Neutral with "justice" not necessarily coming into play. As TV Tropes says, "They'll arrest a robber or rapist, but may also kick a family out of their home for failing to pay rent" even if the family missed rent for a "good" reason. TV Tropes and I agree probably the best example here is Inspector Javert from Les Mis (stealing bread to feed your starving family is no better than stealing cigarettes to hock to school kids). Any other character who is the same staunch type of Legalist would be a Lawful Neutral (protagonist, antagonist, or anyone in between).
 - True Neutral: True Neutrals are either characters who want to "keep the balance" and thus not interfere (think the Elves staying out of things in Lord of the Rings) or characters that don't care about just about anything for one reason or another (be it they're too stupid to realize they should care, have a "calling" they see as above Earthly problems, or just simply want to be left alone).
 - Chaotic Neutral: The Chaotic Neutral is either "the ultimate free spirit" or someone who is just plainly crazy. Chaotic Neutrals don't wish to harm, but neither do they want to help others. Freedom is their be-all end-all. As long as you don't try to rein them in, they really couldn't care less what happens to anyone else.
 - Lawful Evil: Heading into the villains and antiheroes, the Lawful Evil is the "sort of Evil that often ends up in charge." Lawful Evil don't care in the slightest about hurting people, but they care a lot of keeping order (whether because they believe it's intrinsically important or because order is easier to exploit).
 - Neutral Evil: As TV Tropes so gracefully puts it, "Sometimes known as the Asshole Alignment." It doesn't especially matter who gets hurt to the Neutral Evil, and it doesn't especially matter to them if they play by the rules or not. If the rules suit their purposes, they'll follow them. If not, they'll break them. They are often considered more dangerous than the Lawful Evil or Chaotic Evil simply because you never quite know where they're going to swing next. (For those who have read The Copper Witch/The Copper Rebellion, this is where I would honestly place our anti-heroine).
 - Chaotic Evil: Just as interested in being a free spirit as the Chaotic Neutral, the Chaotic Evil is all about doing whatever they want, even if it hurts other (for some, especially if it hurts others). Rather than simply being willing to break rules if they don't agree/they get in their way (like the other Chaotic alignments) Chaotic Evils often take great pleasure in destroying order/causing chaos. Batman's The Joker is perhaps one of the best examples of Chaotic Evil.

 So many narratives appear in life and story when the alignment someone aspires to does not tarry with their true character. The road to hell may be paved with good intentions but the heat from hell lets the angels fly.
 2. Evrémonde says:
 This is the most accurate representation of Game of Throne character alignments I have seen. Some very textbook cases here. GOT characters are the hardest to pin down, they have a wide spectrum of colors, and almost nobody is black and white. The only example I'm not totally sure about is Cersei. I would shift her a little more to the center and label her Neutral Evil along with Little Finger, though you can make an argument for Lawful. Cersei seems frustrated by the limits of her power by following the structure of society, and will disrupt that order if she thinks she can get away with it, expressed fundamentally through her adultery and incest. "If the rules suit their purposes, they'll follow them. If not, they'll break them." I think that's our girl. She doesn't have the strength of conviction, discipline or even enough foresight to stay within the rules.
 3. grace says:
 i would have to disagree and say cersei is neutral evil. she has no regard for the law unless it furthur herself. tywin however, could be a good example of lawful evil.

- Products for Wiser Living
In Vegetable Literacy, Deborah Madison reveals the surprising relationships between vegetables, edible flowers and herbs within the same botanical families, and how understanding these connections can help home cooks see everyday vegetables in a new light.
This groundbreaking new cookbook celebrates the diversity of the plant kingdom. Destined to become the new standard reference for cooking vegetables, it shows cooks that, because of their shared characteristics, vegetables within the same family can be used interchangeably in cooking. It presents an entirely new way of looking at vegetables, drawing on Madison's deep knowledge of cooking, gardening and botany. For example, knowing that dill, chervil, cumin, parsley, coriander, anise, lovage and caraway come from the umbellifer family makes it clear why they're such good matches for carrots, also a member of that family. With more than 300 classic and exquisitely simple recipes, Madison brings this wealth of information together in dishes that highlight a world of complementary flavors. The recipes showcase combinations that are simultaneously familiar and revelatory, such as:
Inspiring improvisation in the kitchen and curiosity in the garden, Vegetable Literacy will forever change the way we eat and cook.

Meaning and history of the St. George Ribbon
The history of the St. George ribbon is inextricably linked with the heroic past of Russia. It is known that it was an integral part of the three insignia established in the name of the patron saint of the Russian army of St. George the Victorious, the order, the cross and the medal. In addition, the ribbon adorned the caps of the sailors who served as part of the Imperial Guard crew, and on ships awarded the St. George flag. It fluttered on the banners of the royal army.
What does the St. George ribbon mean? The story of its appearance
During the period of the military company of _PHONE_, to award those who showed courage, courage and prudence for the benefit of Russia, a special award was instituted - the St. George ribbon. Her motto became the words: "For service and courage." The corresponding award badge appeared - a white equilateral cross or a four-pointed golden star.
There are four order degrees. Cavaliers were first awarded with a cross, a star and a ribbon decorated with stripes of black and orange colors.Heroes awarded the order of the second degree, also had a star and a separate cross, which was worn around the neck. The next degree gave the right to wear a small cross on the neck, and the fourth - in the buttonhole. Since the establishment of the Order, black and yellow colors have become symbols of military valor and courage. Thus, the story of the appearance of the St. George Ribbon can only be considered in conjunction with the history of the order itself.
How the ribbon looked, how it was put on
The tape was worn depending on what class the awarded cavalier was. Three options were envisaged: in the buttonhole, on the neck or over the shoulder. The history of the St. George Ribbon includes such a curious fact: those who were awarded it received a lifetime salary from the treasury, and after their death the heirs became the owners of the award. But the Order of the Statute also provided for the deprivation of the award of those who by some unseemly act had tarnished the honor of the George Knight.
Initially, the St. George ribbon was made of silk and decorated with stripes of black and yellow colors - as it was provided for in the Order Statute of 1769. But if you look at the samples of those old years that have come down to us, then you can see that even then the yellow color on them was clearly to orange, which would only be approved in 1913.For a long time there have been discussions about what the St. George ribbon means.
The story of its appearance is connected with the war, so many believe that black means smoke, and orange means flame. This version, of course, has the right to exist, but the one that was expressed by the well-known expert in the field of phaleristics S. Andolenko is more likely. He draws attention to the correspondence of the colors of the ribbon and the national emblem of Russia - on a gold background a black eagle.
St. George Ribbon. History, meaning and features
There are many order ribbons, but only a few of them have independent status. The history of the St. George ribbon knows the periods when it was used as a full-fledged analogue of the order or the cross. For example, during the Crimean War, the defenders of Sevastopol could not receive the insignia and the ribbons were given to them. Another example is the period of the Imperialist war, when those who were awarded the order pinned a ribbon to the side of an overcoat. But the case is also known when the St. George ribbon was presented without an order and had an independent significance.
This happened in 1914. One of the highest ranks of the General Staff was awarded to her for having managed in the shortest possible time to mobilize the army.Neither the order nor the cross could not be handed, because they were awarded only to participants in hostilities. The tape was granted to him to the earlier order, and thus the general received the right to wear it on the St. George ribbon, which was a unique event in the history of Russia.
Two kinds of tapes
In the reign of Emperor Alexander I, it became a tradition to reward the units that particularly distinguished themselves in military actions with St. George's banners. These award standards differed from others in that the St. George Cross was placed in their upper parts (tops), and under it was a black and gold ribbon with standard tassels. There were no inscriptions on it. Over time, they began to be called "narrow St. George ribbons."
In contrast, the imperial decree of 1878 introduced wide ribbons on which it was written, for what specific services the military unit received this award banner. Such a tape became an integral part of the standard and was not removed from it under any circumstances. Their history begins with the fact that at the end of the military campaign of 1877–1878, Alexander II wished to award the most distinguished units and subunits of the Danube and Caucasian armies that took part in the battles.
Unique rewards for combat regiments
Army commanders provided information about two regiments that fought under their command. A detailed list of their exploits was attached to the report. But when the relevant commission began to consider the issue of awarding, it turned out that these regiments already had all the awards that existed at that time. It was for them that the wide St. George ribbon was established, listing their merits.
More similar ribbons were not awarded, and these two regiments were forever the only ones who were awarded this honor. It is known that at the end of the Crimean War, by the decree of the emperor, a nominal award weapon, decorated with the straps of flowers of the St. George ribbon, was introduced. Such an award was considered no less honorable than the Order. Samples of this golden weapon can be seen today in many museums in the country.
Hall of the Palace, dedicated to the gentlemen of the Order
In St. Petersburg in the royal residence at the end of the XVIII century, the Great Throne Hall was opened. His consecration took place on November 26 on the day of the celebration of the memory of St. George the Victorious. In this regard, he was named after him. Since then, all protocol events related to the awards were held precisely within its walls.There also sat a commission that considered the candidacies of the next cavaliers, and receptions were held annually in honor of his cavaliers.
Awarding ribbon in the White Guard troops
After the seizure of power in 1917, the Bolsheviks abolished the old award system, and the black and gold ribbon was used only in parts of the White Army. An example is its presentation along with the sign "For the Ice Campaign", used in the award system of the Volunteer Army of Kornilov. Also on the Eastern Front, it was attached to the medal "For the great Siberian campaign."
In addition, the history of the St. George Ribbon knows many facts of its use as patriotic symbolism by many White Guard units and formations. Ribbons with black and orange stripes decorated the banners, chevrons and hats of soldiers and commanders. This was especially characteristic of the participants in the Yaroslavl uprising. The famous ataman Annenkov obliged the veterans of his movement to wear St. George ribbons to distinguish them from the newly called soldiers.
Allies of enemies and fighters against Bolshevism
In 1943, the German command formed the so-called Russian corps, consisting of immigrants and former citizens of the USSR, who had gone over to the side of the enemy.It was used to suppress the resistance of the Yugoslav partisans, and its most distinguished members were awarded St. George crosses and ribbons. Unfortunately, not only the heroic pages contain the history of the St. George ribbon. Vlasov, who fought in the ranks of the Wehrmacht, also often carried this sign of valor on their chests.
In 1944, a collaborationist organization was created in Bobruisk, called the Union Against Bolshevism. On his banner, decorated with two-color ribbons, an image of St. George cross was embroidered with silver. The same tapes served as armbands and distinctive signs of its leaders. Among the numerous unions created in the West by Russian immigrants, all sorts of symbols were popular, including St. George ribbon. One of these organizations was the Russian All-Military Union.
The continuation of the patriotic tradition
St. George Ribbon, the history of which is closely connected with the heroic pages of the Russian-Turkish war, eventually entered into the symbolism of the Soviet army. In 1942, at the height of the battles against fascism, the Guards Ribbon was established,corresponding in appearance to the well-known Georgievskaya. This was a continuation of the glorious patriotic tradition.
It was used on the Red Navy caps and as a breastplate "Sea Guard". The image of the ribbon were decorated with banners of guards units, formations and ships. In 1943, a ribbon of the Order of Glory was established by government decree. Its appearance is completely identical to St. George. It was also used to design the pads of the medal "For the victory over Germany."
The revival of glorious awards
With the advent of democratic changes in the country, the attitude towards the monuments of our history has changed in many ways. A government decree of March 2, 1992 restored the Order of St. George and the insignia of the Cross of St. George. In 2005, in honor of the

Alejandra Laviada, Haiku, 2019, Acrylic paint on pigment photographic print, 81 x 61 cm, Bendana | Pinel Art Contemporain & artist
Founded in 2008
4 rue du Perche
BENDANA | PINEL
Painted Geometries is Alejandra Laviada's most recent work and reflects her ongoing interest in exploring the relationship between photography, painting and sculpture. Having started her career in painting and later delving into photography, Laviada's practice centers around creating works that rise from the intersections between these different mediums. The resulting images defy being categorized into a single type, and aim to question and redefine photography's shifting role within the context of contemporary art.The photographs depict various wooden objects that are painted white and photographed. The surface of each photograph is then hand painted to create a new image composed of different geometric shapes. The white brushstrokes visible on the wooden objects put into question which parts of the image are photographed and which ones are painted, blurring the lines between representation and abstraction, between the real and the constructed.


Part 3: Running OVSDB between Juniper QFX5100 and VMware NSX for vCenter
The following components were used for this example:
 - VMware NSX for vSphere 6.2.0 Build _PHONE_
 - Juniper QFX5100, Junos 14.1X53-D27.3, SDN Package Version 14.1X53-D26.2
The very first step on the QFX5100 is to configure it to run
OVSDB and establish a communication channel to the
NSX controller.
In the example, the NSX controller is having the IP address
The Loopback interface is configured as vtep-source interface. This means that any packet that gets encapsulated by VXLAN is using as source IP address. The destination address is the VTEP IP address of the destination hypervisor or ToR Switch.Additionally, we instruct the switch which interfaces should be controlled by the NSX controller from now on. In this example we use ge-0/0/4. There should be no configuration on the interface.
In the vSphere Web Client we go to „Network and Security" => „Service Definitions" => „Hardware Devices" and click the green „+" to add a new device.
A hardware switch is identified by a name and a certificate which needs to be entered as shown below:
The certificate needs to be installed on the switch before contacting the NSX controller. The NSX controller uses the certificate to identify incoming connections for the exchange of OVSDB information.
After adding the device, a new entry shows up in the vSphere Client showing that the session is established.
On the Juniper Switch we can verify the control-session with a simple command:
Attaching Hardware ports to logical switches
Hardware ports can be attached in vSphere Web Client with „Networking and Security" at the following places:
 - Service-Definitions => Hardware Devices => right-click on device => Attach Logical Switch
 - Logical Switches => right-click on logical switch => Attach Hardware Port
Within NSX, Virtual Networks (VNs) are referred to as logical switches.
In this case we have a logical switch called "VN 1" that we link to the
hardware device and the physical port that should be attached as shown below.
NSX will only show available ports that have been enabled for OVSDB, in our case ge-0/0/4.
After confirming the change, the following configuration will automatically
become active on the QFX5100 for an untagged port.
If a port is tagged with a VLAN-ID of 100 on the NSX controller,
the following configuration would be seen on the QFX5100:
The Juniper Switch performs the configuration of the VXLAN and interface automatically based on the information
received via OVSDB from the NSX Controller. The name of the VLAN is actually the identifier of the logical switch in the NSX database. In order to check the status of the configured VXLAN the following command can be used.
A successful configuration on both sides of the OVSDB exchange can be confirmed by the flag „Created by both". Additionally, the MAC table of this virtual network can be seen on the QFX Switch.
The IP Address is the loopback of the QFX5100 switch that is used as tunnel source address. The address is the address of an ESXi hypervisor which is hosting a virtual machine which is part of the same logical network.
When capturing a live communication between the virtual machine 00:50:56:ad:02:32 located on hypervisor and the physical host 2c:6b:f5:7d:49:f7 which is a connected on the QFX switch, we can see how the overlay network works in practice.
The outer IP header shown in line three has been used by user datacenter network to forward the packet. We can see that the addresses here are actually the same that were shown in the command above as VTEP addresses.
Following the IP header we can see the VXLAN header with a VNI of 5004. The VNI is associated to a virtual network, as soon as it is created in NSX. The QFX5100 switch got this piece of information from the NSX controller via OVSDB when we associated the physical port with the virtual network. This field is used on the egress hypervisor / ToR Switch to match the packet into a certain virtual network.
In the following lines we finally can see the actual MAC addresses of the devices that were part of our example.
