kasai rex by O055uE8i
 The Kasai Rex is a strange animal allegedly living in the jungles of central Africa said to
resemble a large, predatory dinosaur.
There have been several sightings throughout the years, but the most popular one took place in
1932. A Swedish plantation owner, named John Johnson, and his African servant were once
walking through the Kasai valley in Africa (the location of this particular sighting was where the
creature got its name), when they came across a grazing rhinoceros. They were careful not to
disturb the animal. All of a sudden, a 40-foot-long, two-legged lizard-like beast ambushed the
rhino. During this attack, Mr. Johnson actually fainted while his servant ran away in terror.
When Johnson woke up, the creature was still feeding on the rhino carcass. He described the
animal as having have long, sharp teeth, big jaws, a long, thick tail, and thick legs, which he said
reminded him of the legs on a lion. He also described the color of the creature: a dark red, with
dark-colored, vertical stripes running down its neck, back and tail. He then saw the huge beast
walk back into the jungle after it had eaten its fill.
The few sightings of this creature generally agree with one another; the size of the creature
differs slightly in the sighting descriptions (possibly due to specimens of a different sex or age),
but the animal's coloration remain the same: red with dark stripes.
These general descriptions certainly seem to fit a large carnivorous dinosaur. Candidates include
not just T-rex, but also Tarbosaurus (a very close relative of Tyrannosaurus rex), Allosaurus,
Megalosaurus, and the recently discovered Giganotosaurus, among others.
No expeditions have yet been launched that have focused on the Kasai Rex.

Several installations in the Defenses of Washington, the ring of forts built around Washington, D.C., to protect the federal capital during the Civil War, were located close to and in Alexandria.
Unlike Fort Ellsworth and Fort Ward, which were positioned on higher inland elevations to the west, Battery Rodgers was located along the Potomac River, just south of the existing city limits.
Battery Rodgers was named for George W. Rodgers, a U.S. naval captain who was killed in 1863 during an attack on Fort Wagner at Charleston, S.C. Battery Rodgers was strategically positioned on a bluff at Jones Point, on the western side of the Potomac with Fort Foote, located about two miles south on the opposite side in Maryland. In this location, Battery Rodgers was able to guard against Confederate ships on the Potomac and enemy approaches by land to the south.
Plans for the water battery, as it was sometimes referred to, included a 185-foot-long main face, five 200-pounder Parrott rifles, one 15-inch Rodman gun, and two magazines. In this 1864 photograph, the door to one of those magazines is visible on the left, as is the Rodman gun. The gun was large enough for a person to crawl inside it and at least one man was photographed inside doing so. Additional facilities for this fortification included barracks, a mess hall, prison, hospital and slaughterhouse.
No remains of Battery Rodgers exist today, but markers along the waterfront and at the intersection of South Lee and Green streets recall its history.

text: Wytham Woods is a mixed deciduous forest in southern England. It covers approximately 400 ha, which is a relatively large woodland for the UK and includes a range of different soil types and management histories. Wytham is owned by Oxford University and is used by the Centre for Ecology and Hydrology (CEH) as a long-term monitoring site in the UK Environmental Change Network (ECN). A flux tower has occasionally operated on the site, measuring stand-scale carbon and water fluxes; a canopy walkway gives access to the leaves of canopy trees, and several studies of tree ecophysiology have been carried out there. A network of small (10 m x 10 m) ECN forest-monitoring plots is distributed across the site, and a 1-ha plot forms a focus for carbon-dynamics studies, including soil processes and tree growth. The core ForestGEO plot covers 18 ha (300 m x 600 m), and has been surveyed in detail by airborne lidar and hyperspectral sensors, and by terrestrial lidar.

How to detect the quality of potentiometers?
1.The circuit graphic symbol of the dual coaxial potentiometer in the circuit is shown in figure 1. When the pointer multimeter is used to detect the quality of the double coaxial potentiometer, the suitable electrical barrier of the multimeter is selected according to the resistance value of the detected double potentiometer.
First, the detection method of resistance value.
The resistance values of two groups of potentiometers on the double potentiometer are measured by using the two pens of the pointer multimeter, that is, the resistance values between A and C and A 'and C' in figure 4. Under normal circumstances, the resistance values of the two should be basically the same.
Fig. 1 the circuit graphic symbol of the double coaxial potentiometer in the circuit.
Second, the detection method of synchronization performance.
The A and C and A and C ends of the detected double potentiometer are short connected by a short wire, and then the resistance value between the center head B and B'of the potentiometer is measured by using a multimeter two-meter pen. Under normal circumstances, no matter where the shaft of the double potentiometer turns, the resistance value between the two points B and B should be equal to the resistance value between A and C or between A and C, that is to say, The pointer to the multimeter should always remain unchanged at the scale of the A and C or A' and C resistance values.
If the pointer of the multimeter is found to deflect, it means that the synchronization performance of the detected double potentiometer is poor and cannot continue to be used.
2. A method of detecting an adjustable resistor.
Adjustable resistor is also called adjustable potentiometer and fine-tuning potentiometer. Because of its small size, its rotating Reed is easy to loosen. When testing, you can use a multimeter to measure the resistance on both ends of the foot. If there is no indication of resistance value, it indicates that the Reed is loose or the diaphragm has been burned out; If the Reed is loose, you can clamp it with a pointed mouth clamp, measure the resistance between the middle pin and any pin on both sides, and rotate the Reed at the same time to see if the pointer on the table changes with the rotation angle, and if there is no change, it is damaged.
For the fine-tuning potentiometer with poor contact, it can be cleaned with gasoline or alcohol first, and then the new parts can be replaced when the cleaning is invalid.

Roaring River State Park, nestled among the hills of southern Barry County near Cassville, draws visitors from across Missouri and neighboring states. Although the 4,093-acre park offers camping and hiking opportunities, its main appeal is trout fishing.
Roaring River Hatchery, which is operated by the Missouri Department of Conservation, produces more than 250,000 rainbow and brown trout each year. Most of those fish end up in the upper 1.7 miles of Roaring River that is within the park boundaries. The stream originates at Roaring River Spring—one of the park's many scenic features. The 20 million gallons of cool water that flow from the spring daily make trout rearing and trout fishing possible at the park.
A Natural Choice The spring—and the cool water that gushes from it—prompted Roland Edward Bruner to construct the first trout hatchery at the site in 1910. Bruner was born in 1860 in Pennsylvania and later moved to Wellsville, Kansas, where he married Hannah McLain in 1883. Among his many careers, he was a miner and progressed from prospector to president of the Anaconda–Arizona Mining Company. His business took him around the country, including the Ozarks. He also traveled to Colorado, where he became interested in rainbow trout, not so much in how to catch them but in how to raise them.
The fish hatchery Bruner built included a small hatchery building on the northwest corner of the spring pool's dam and several raceways.
Bruner started with trout that were shipped by railroad from Colorado to Monett about 25 miles to the north. He put a tank on his pre-1910 model truck to carry the trout from the railroad landing to Roaring River, a trip which included seven miles of extremely poor roads.
Much of the information on Roaring River's early days comes from Roland and Hannah's granddaughter, Betty Bruner Layton, who lived in the park until she was 5 years old. Before the U.S. entered World War I, her father, Roland Bruner Jr., left college at the University of Missouri in 1916 and joined the American Field Service in France to fight the Germans. He was wounded and returned to the U.S. in 1917. He came to Roaring River to heal and to help his father with his hatchery.
Roaring River was self-sufficient in those days. Betty remembers guests picking out trout in the raceway near the hotel for dinner. The restaurant would prepare the trout and serve it with a watercress


We have a glass fuse for a 12v lighting circuit that has "Siran No. F 13 4A" written on paper inside it. The circuit takes 5.5A at the moment with all the lights switched on without the fuse blowing. Can someone tell me what this is rated at? It seems to be a fast blow (F) so can it really be a 4A?
I figure my options are
13A (so what does the 4 mean?)
4A (why is it still working at 5.5A?)
Thanks for reading, Steve
Edit: Images added as requested. Fuse shown with left side in holder Fuse with writing fuse wire
 - \$\begingroup\$ Can you make a picture? Normally the F13 stays for dimensioning and type and 4A the current. It still can be a slow blow fuse. \$\endgroup\$ – rfkortekaas Dec 31 '15 at 9:59
It might be a 4A fuse allowing 5.5A at the moment. To understand why/how this can happen, you need to know the working of a fuse. The fuse will have some finite resistance R and a current I through it will start adding heat to the fuse as per the equation - IxIxRxt where t is the time. This heat energy will raise the temperature of the fuse and at one point, it will melt. However this isn't the only thing going on in there. The fuse is also losing some of the heat to its surroundings and hence the surroundings also play a role in deciding the current at which the fuse will blow and the time it will take to blow. Here is an excerpt from a fuse sizing guide:
Fuse selection guide
Fast fuse
In your case, one of the following might be the case:
1) Lack of quality control - Maybe the fuse company didn't control the tolerance very well.
2) Fuse is losing too much heat to its surroundings.
3) Fuse is not a fast one and it might blow given enough time.
4) It's not a 4A fuse.
 - \$\begingroup\$ Thanks for that. I'm guessing that the next step would be to figure out the gauge of the wiring and get a suitable fuse? This is the only time I've ever switched on all 5 lights - regular use is 2 or 3 at the most. \$\endgroup\$ – Steve Dec 31 '15 at 12:15

Delesseria decipiens Ecology
decipiens lives in low intertidal to subtidal areas on the west
coast of North America, from Alaska to San Luis Obispo, CA. D.
decipiens is saxicolus,
meaning that it grows on rocks and can be found on the vertical faces
of rocks in the low intertidal areas. D.
decipiens was first collected in 1859 in the Straits de Juan de
Fuca, near present day Washington State. Samples of D. decipiens were
found in the Hopkins Marine Life Refuge growing on buoy lines in late January
and early March. Data collected from the Gilbert M. Smith Herbarium
also indicates that D. decipiens grows in
a wide variety of locations around the Monterey and Carmel Bay areas.
Locations of D. decipiens in the past have included, from north
to south, Point Pinos, Moss Beach, Asilomar, Spanish Bay, Point Joe,
Cypress Point, Pescadero Point, Pebble Beach, Stillwater Cove, Carmel
Beach, Mission Point and Soberanes Point. Herbarium notes suggest that D.
decipiens can grow in a tidal range form 0.5 to -1.5 feet, although
some sources indicate that it grows at depths of 20 feet. Map
of coastline of the Monterey Peninsula.

Seasonal Growth Delesseria
decipiens is a spring annual that can be found in the Monterey
Bay region from late January to July. Based on a survey of D. decipiens samples
in the Gilbert M. Smith Herbarium, plants seem to reach their maximum
size, as measured by the length of their primary midrib, in May and
June. There did not appear to be any pattern of reproductive development
with samples becoming reproductively identifiable in April and continuing
Sensing UV Light Studies done in Delesseria sanguinea have shown that D. sanguinea is a sensitive and reliable indicator of UVB light, demonstrating a significant reduction in growth rates when compared to exposure to visible sunlight and UVA light alone. This is significant as continued thinning of the ozone layer allows more UVB light to reach the earths surface. UVB is a highly destructive form of UV light and accurate indicators such as D. sanguinea could be highly valuable in monitoring the effects of UVB levels on biological life. It is not currently know whether D. decipiens shares the same UVB sensitive properties, but testing this property could be an area of further research.
Delesseria decipiens as a habitat Delesseria decipiens can act as a habitat for other invertebrates and marine organisms. In a sample collected on March 4, 2004 from a buoy line several invertebrates were found in association with D. decipiens. These invertebrates included several caprellids, called skeleton shrimp (Phylum Arthropoda, Class Crustacea, Order Amphipoda), a tiny nudibranch (above right) Coryphella trilineata (Phylum Mollusca, Class Gastropoda, Order Nudibranch), several acorn barnacles of the genus Lepas (Phylum Arthropoda, Class Crustacea. Order Thoracica), and an unidentified worm from the phylum Nemertea about 2mm long.

MultiMarkdown footnotes in TextMate
Earlier this week, there was a thread on the TextMate mailing list about creating footnotes in text files. It was suggested that MultiMarkdown had a good footnote implementation and that my reference link macro/command/snippet system could be modified to make MultiMarkdown footnotes. As I was going to be spending some downtime this week flying and sitting in airports, I told the list I'd work it out and get back to them. So, thanks to a couple-hour delay at O'Hare, here it is.
The MultiMarkdown way of making footnotes follows the method described in this Markdown mailing list thread. It is apparently the format favored by John Gruber when he writes his Daring Fireball posts even though it hasn't made its way into his version of Markdown yet. Basically, you stick [^x] at the point you want the footnote marker to appear, and [^x]: footnote text at the bottom of the document. The "x" between the square brackets can be any string of characters. The format is basically the same as that for reference-style links, but with the addition of the caret character (^), which cleverly suggests the superscript commonly used for footnote markers.
As with the reference-style link system, the footnote-making system consists of a command that inserts a snippet and a macro that calls the command.
First, we create a new command called "Footnote" in the Markdown category of the Bundle editor and insert the following Perl code:
use List::Util qw(max);
$text = $text. "\n" unless substr($text, -1) eq "\n";
# Get the highest-numbered footnote.
_USER_ = $text =~ /^\[\^fn(\d+)\]: /mg;
$n = max(_USER_) + 1;
# Escape special characters.
$text =~ s/([\$\\'])/\\$1/g;
# Insert the snippet.
print '[^${1:fn'. $n. '}]$0'.
 $text. '[^$1]: ${2:footnote}'. "\n\n";
This command assumes that all the text is selected from the point at which the footnote marker is to appear to the end of the file (that's the $ENV{'TM_SELECTED_TEXT} part). Your Bundle Editor window should look like this:
(Click on the screenshot to see it full-sized.)
We now create a macro that makes that selection and calls the command. Start with a file that has some text and a couple of blank lines at the end. Then:
 1. Put the caret somewhere in the text. (At this point it doesn't really matter where, but to get a feel of how the macro will work, you'll probably want to put it where you want the footnote marker to appear.)
 2. Choose Start Macro Recording from the Automation menu.
 3. Press Command-Shift-Downarrow to select all the text from the caret to the end of the document.
 4. Invoke the Footnote command by choosing it from the little gear-like popup menu along the bottom of the TextMate window.
 5. Choose Stop Macro Recording from the Automation menu.
 6. Click anywhere in the document to deselect the footnote marker and interrupt the snippet.
 7. Press Command-Z to undo the snippet.
At this point, it's probably best to test out the macro a few times by choosing Replay Scratch Macro from the Automation menu. When you're convinced it's working, choose Save Scratch Macro… from the Automation menu and save it with the name "Footnote" in the Markdown section. Use whatever Tab Trigger or Key Equivalent you like (I chose a Key Equivalent of Control-F) and set the Scope Selector to "text.html.markdown." Your Bundle Editor window should now look like this:
To use the macro, put the caret where you want the footnote marker to appear and invoke the macro. The footnote marker, [^fn1], will appear at the caret position with the "fn1" selected and [^fn1]: footnote will appear at the bottom of the document. You can now type a new marker or just hit the Tab key to change the selection to the "footnote" text. When you're done changing the footnote text another press of the Tab key will move the caret back to the end of the footnote marker. If you left the footnote marker as "fn1," the next time you invoke the macro, the marker will be "fn2," and the time after that it will be "fn3," and so on. Please note that, as with the leading number in ordered list items, the number in your marker may not be the number that shows up in the HTML output.
There are two oddities you may be wondering about:
 1. Why [^fn1] and [^fn2] instead of just [^1] and [^2]?
 2. Why is there a blank line after each footnote?
The simple answer to both these questions is that MultiMarkdown won't work otherwise. I haven't looked into the code to see why, but MultiMarkdown doesn't recognize footnote markers with just a single digit after the caret. And it also gets confused by multiple footnotes unless they're separated by a blank line. My first thought is that restrictions are bugs in the implementation, but maybe there's a good reason for them.
One more thing. If you start using footnotes and processing them through MultiMarkdown, you'll soon find you need to create a "footnote" class in your CSS stylesheet. Otherwise, the footnote numbers will not be superscripted. And you'll have to create a "reversefootnote" class if you want the footnotes themselves to have a different style (e.g., a smaller font size) than the regular body text.
Happy footnoting!


Developer Evangelist
What Does Developer Evangelist Mean?
A developer evangelist is a specific role within a company's engineering team that is focused on bridging internal and external communications. The developer evangelist typically maintains a presence as an "ambassador" for the company, interacting with the outside world through social media and in person.
A developer evangelist is also known as a technology evangelist, technical evangelist or technology advocate.
Techopedia Explains Developer Evangelist
A developer evangelist is typically a skilled developer, but does not actually spend most of his or her time writing code. Instead, the developer evangelist is essentially going out into the community to spread the news about what his or her company is doing, build relationships, and participate in a kind of "developer ecosystem." Part of this job would often entail communicating with both corporate developers, and those working on open-source technologies who are unconnected to a proprietary license product and brand.
The developer evangelist job is heavy on communications. In posting a job opening for this particular role, a Microsoft post defines the developer evangelist's mission as "to secure platform adoption and revenue growth through evangelism, community engagement, relationship marketing and a vibrant solutions ecosystem."
Experts point out that developer evangelists need both technical and communication skills, a passion for technology, and ways to articulate technical concepts to diverse audiences.

Researchers look beyond 20/20 vision with 3D-printed eyes
3d printed bionic eyeball eyes
More often than not, the discussion around 3D printing human body parts revolves around internal organs, as the lists of people awaiting transplants from worthy donors is always shockingly long. However, one company, MHOX, has been working on a conceptual design for an advanced bio-printed eyeball, which would allow people to see again if struck with disease or trauma and may even give them a chance to see better than any human in history.
The eyeball concept actually comes in three different flavours. The first would provide the same functionality as our eyes do now and would be the economical version of the trio. The second, slightly more advanced iteration, could provide more advanced focusing capabilities, giving those fitted with the new eye 15/10 vision.
Related: What is 3D printing? A beginner's guide to the desktop factory
The third version would also be WiFi capable and would have the ability to record what you're seeing and automatically upload it. To activate some of these functions however, the wearer would need to swallow a pill containing certain enzymes which would then trigger WiFi connectivity or photo mode for a certain period of time, according to Dezeen.
Regardless of which version you used however, MHOX sees the process of 'implantation as largely the same. Each would involve the removal of the original eyeball, and a piece of organic hardware known as 'the deck' would be installed, acting as an interface between the optic nerve and the new eye. The eyeball itself would be printed using what researchers descibe as "bio-ink," of several different types, each containing different cells. Those cells could then be printed out in various configurations depending on which eye is being made.
Speaking about the feasibility of such technology, MHOX partner and lead designer Filippo Nassetti said: "This project is a concept design based on an intuitive vision of how existing technologies might evolve. We forecast that bioprinting and biohacking would have made impressive advances by 2027."

Developing a Water Management Plan
A comprehensive water management plan helps kick-start a successful water management program by helping a facility set water conservation goals and identify water conservation opportunities. The plan should include clear information about how a facility uses its water, from the time it is piped into the facility through disposal. Knowledge of current water consumption and its costs is essential for making the most appropriate water management decisions. This page includes helpful hints in developing a water management plan. You can also view completed water management plans for many of EPA's facilities.
A focal point of water management plans is the Best Management Practices (BMPs) section. BMPs are designed to consider all of the various uses of water and maximize conservation. BMPs can be categorized to either maximize water efficiency or minimize water use. Following are 14 BMPs as recommended by the Federal Energy Management Program:
- BMP #1 - Water Management Planning
- BMP #2 - Information and Education Programs
- BMP #3 - Distribution System Audits, Leak Detection and Repair
- BMP #4 - Water-Efficient Landscaping
- BMP #5 - Water-Efficient Irrigation
- BMP #6 - Toilets and Urinals
- BMP #7 - Faucets and Showerheads
- BMP #8 - Boiler/Steam Systems
- BMP #9 - Single-Pass Cooling Systems
- BMP #10 - Cooling Tower Systems
- BMP #11 - Commercial Kitchen Equipment
- BMP #12 - Laboratory/Medical Equipment
- BMP #13 - Other Water Use
- BMP #14 - Alternate Water Sources
Elements of a Proper Water Management Plan
A water management plan can be divided into three components: water accounting, BMPs achieved, and water management opportunities. To develop a proper facility water management plan, it is important to include the following elements, at a minimum:
- Operation and Maintenance (O&M). Appropriate O&M recommendations from the BMPs are included in facility operating plans or procedure manuals.
- Utility Information. Appropriate utility information includes the following:
- Contact information for all water and wastewater utilities.
- Current rate schedules and alternative schedules appropriate for usage or facility type. This helps ensure that you are paying the best rate.
- Copies of water/sewer bills for the past two years. This will help you identify inaccuracies and determine whether you are using the appropriate rate structure.
- Information on financial or technical assistance available from the utilities to help with facility water planning and implementing water efficiency programs. Some energy utilities offer assistance on water efficiency.
- Contact information for the agency or office that pays the water/sewer bills.
- Production information, if the facility produces its water and/or treats its own wastewater.
- Facility information. At a minimum, perform a walk-through audit of the facility to identify all major water-using processes, determine the location and accuracy of water measurement devices and main shut off-valves, and verify operating schedules and occupancy of buildings. To meet reporting requirements in Executive Order 13423, facilities should include a description of actions necessary to improve the accuracy of their water usage data. Activities can include a metering (or other measurement) plan for the facility.*
- Emergency response information. Develop water emergency and/or drought contingency plans describing how your facility will meet minimum water needs in an emergency or reduce water consumption in a drought or other water shortage. This should be done in conjunction with your local water supplier.
- Comprehensive Planning. Inform staff contractors and the public of the priority your agency or facility places on water and energy efficiency. Ensure appropriate considerations are taken into account early in the design and planning of any new or retrofit project.
* In order to properly manage water conservation projects, it is important that all water be accounted for through precise measurement, such as water meters. It is necessary to have measurements not only to plan how to address water conservation, but also to monitor and track progress made in these programs as well as to adjust and make changes.

General Lifestyle Survey
(formerly called the General Household Survey)
The General Lifestyle Survey (in its previous incarnation as the General Household Survey) used to be one of the most used government surveys. However, with new, larger surveys introduced over the last decade, particularly the Family Resources Survey, it is now used much less often. In effect, its main uses are when Great Britain-wide results are required and none of the other surveys have the required data. This means that its uses are largely limited to analyses by:
- Limiting long-standing illness or disability.
- Available from: UK data archive.
- Registration required: yes.
- First survey available: 1971.
- Frequency: annual.
- Updated: May.
- Scope: Great Britain-wide (i.e. does not include Northern Ireland).
- Format: SPSS, STATA or TAB.
- Files: two files per year, one at the individual level and the other at the household level.
- Documentation: comprehensive.
- Weighted or unweighted: weighted from 1998/99 onwards but unweighted for earlier years.
- Household income data: yes, equivalised.
Note that, prior to 2008, the equivalent survey was called the General Household Survey (GHS).
Also note that:
- Prior to 2005, each dataset covered a financial year rather than a calendar year.
- There was no survey in either 1997/98 or 1999/00.
In addition to the dataset itself, ONS publishes an annual report giving many statistical analyses from the dataset.
Which software to use
As the annual dataset is around 30,000 records for individuals and 10,000 records for households, it can be exported into Excel.
When to use the individual and household datasets
Use the household dataset when the desired analysis relates to households. When the desired analysis relates to individuals use either the individual dataset and/or the household dataset depending on which has the variables that are required. If the required variables are in the household dataset then the analysis can be undertaken in either of two ways:
- by linking the two datasets together using the household serial number as the key; or
- by using the household dataset but multiplying the household weights by the number of people in the household to get individual weights.
Note that children have a null weight in the individual dataset so any analyses at the individual-level are actually analyses for adults only.
Because the dataset is for Great Britain only, the graphs below are also for Great Britain only.
|Working-age limiting long-standing illness or disability||individual||first three||Use ONS mid-year population estimates as necessary to translate proportions into absolute numbers.|

How to Review Activities on Salesforce
You can use activities in Salesforce to track all the significant tasks and events involved in acquiring, selling, and servicing customers. Think about all the actions that you and your teams perform to accomplish your job — meetings, calls, e-mails, even the occasional physical letter — and imagine the value of all that information in one place at your fingertips.
You can have such a place in Salesforce, and you can easily link your activities together in an organized fashion.
Salesforce features several types of activities that you can access from the Open Activities and Activity History related lists displayed on many of the major records, including accounts, contacts, leads, opportunities, and cases. The following list briefly explains all the various activity records you can track in Salesforce:
Task: Essentially a to-do. Use this activity record as your online yellow sticky note. It's an activity that needs to be completed, but it doesn't have a specific time or duration associated with it. For example, if you know that you're supposed to follow up with a contact by sending a written letter, you can create a task such as Send Letter.
Event: A calendared activity. An event has a scheduled time, date, and duration associated with it. Examples of common events are Meetings, Conference Calls, and Tradeshows.
Log a Call: A task record of a completed call. Use Log a Call during or after a call to make sure that you capture important details. For example, use it when a contact calls you and you want to record comments or outcomes from the discussion.
Send an Email: Logs an activity for an e-mail that you send to a contact or a lead. You can send e-mails from Salesforce or a third-party e-mail product like Microsoft Outlook or Gmail for Business, and capture that information directly inside Salesforce.
Salesforce's online suggestion box feature, also known as Salesforce Ideas, allows you and a community of other Salesforce users to post suggestions on any topic for others to vote on and discuss. Ideas can be used just internally within your company and among your peers, or to gather requests from external constituents like your customer base.
This sharing of ideas is a valuable way for your company to mine feedback that could result in product or service innovations, or process changes. Ideas are ranked based on popularity over time, and you can group Ideas into multiple subject areas.

In order for students to understand S.E. Hinton's novel The Outsiders completely, they must understand the music of the time and how it relates to the novel's main characters. In the novel, different groups of characters emerge and Hinton distinguishes these groups by associating them with musicians of the time. She realtes The Beatles to the Socs, Elvis Presley to the Greasers, and Hank Williams, Sr. to a rougher subculture of Greasers. Unfortunately, many students are not familiar enough with these early popular music artists to grasp Hinton's use of them in her novel. Therefore, in this lesson, students will gain an understanding of these and other musicians and how they relate to the novel's themes of forbidden love, friendship, and social ostracism.
Students will be able to:
- Recognize themes in The Outsiders and popular music.
- Recognize social ostracism in their own lives.
- Recognize different genres of popular music.
This lesson is designed for middle school students (seventh and eighth grade) reading S.E. Hinton's novel The Outsiders. However, it could be used with younger or older students reading a similar text.
In order to promote healthy class discussion, this lesson should be completed in roughly three fifty-minute class periods.
The lyrics and recordings of selected recordings; copies of S.E. Hinton's novel The Outsiders; a modified version of Paul Friedlander's Rock Window*
For this lesson to be most effective, students should have read nearly half of the novel. At that point, they will be able to recognize the themes of forbidden love, friendship, and social ostracism. Biographical information from the Rock and Roll HaIl of Fame website (_URL_) should be shared on Elvis Presley, The Beatles, Hank Williams, Sr., Bob Dylan, and The Who. Also, the phrase "social ostracism" should be defined and discussed with students.
- "Heartbreak Hotel": Discuss this song using the modified Rock Window. Discuss how this song relates to the theme of forbidden love in The Outsiders, specifically concerning Cherry and Ponyboy. Discuss why the Greasers might relate to Elvis Presley.
- "You've Got to Hide Your Love Away": Discuss this song using the modified Rock Window. Discuss how this song might relate to the theme of forbidden love in The Outsiders, specifically concerning Cherry and Ponyboy. Discuss why the Socs might relate to The Beatles.
- "I'm So Lonesome, I Could Cry": Discuss this song using the modified Rock Window. Discuss how this song might relate to the theme of social ostracism in The Outsiders, specifically concerning the Greasers. Discuss why the Greasers might relate to Hank Williams, Sr.
- "Two of Us": Discuss this song using the modified Rock Window. Discuss how this song might relate to the theme of friendship in The Outsiders, specifically concerning Ponyboy and Johnny.
- "A Hard Rain's A-Gonna Fall": Discuss this song using the modified Rock Window. Discuss this song in relation to The Outsiders. Would the Socs or the Greasers relate to this song?
- "My Generation": Discuss this song using the modified Rock Window. Discuss this song in relation to The Outsiders. Would the Socs or the Greasers relate to this song?
In small groups, students are to select three modern songs. One of these three songs must relate to the theme of forbidden love, another to the theme of social ostracism, and a third to the theme of friendship. Lyrics to these songs are to be submitted with an essay explaining how the songs relate to the themes and to The Outsiders. If class time is available, students could present their songs and rationale to the class.

Is fluid pressure from below influential? Is soil type influential?
How about the purity of the water?
It's 32 ft, and that applies to siphoning. Capillary action is different

Bates numbering
From Wikipedia, the free encyclopedia
 (Redirected from Bates number)
Jump to: navigation, search
Bates Automatic Numbering-Machine, circa 1906, with a number printed by the machine.
Bates numbering (also known as Bates stamping, Bates branding, Bates coding or Bates labeling) is used in the legal, medical, and business fields to place identifying numbers and/or date/time-marks on images and documents as they are scanned or processed, for example, during the discovery stage of preparations for trial or identifying business receipts. Bates stamping can be used to mark and identify images with copyrights by putting a company name, logo and/or legal copyright on them. This process provides identification, protection, and automatic consecutive numbering of the images.
The Bates Automatic Numbering-Machine or Bates stamper is named after the late 19th century inventor Edwin G. Bates of New York City. He obtained several United States patents for the device from 1891 to 1901 and the patents were assigned to the Bates Manufacturing Company.[1][2][3] The earliest patent claimed a "new and useful improvement in Consecutive-Numbering Machines", indicating that Bates was not the originator of the idea. Bates' objective was "generally to increase the effectiveness, simplicity and compactness of machines of this general character". Each time the machine was pressed down onto a sheet of paper, a rotating wheel was moved incrementally. The original machine described by Bates allowed numbering with a four-digit sequence, ranging from 0000 to 9999. For example, page 852 in a document set would be 0852. Courts and law firms quickly adopted this system.
General Binding Corporation (GBC) acquired Bates Manufacturing Company in 1993. As of 2011, Bates numbering machines are sold by Advantus Corporation of Jacksonville, Florida, which acquired the product line from GBC.
Bates numbering is commonly used as an organizational method to label and identify legal documents. Nearly all American law firms use Bates stamps, though the use of manual hand-stamping is becoming increasingly rare due to the rise in electronic numbering — mostly in Portable Document Format (PDF) files, rather than printed, material. During the discovery phase of litigation, a large number of documents might require the use of unique identifiers for each page of each document for reference and retrieval. Bates numbering, named for the Bates Automatic Numbering-Machine, assigns an arbitrary unique identifier to each page. Such identification may be solely numeric or may contain a combination of letters and numbers (alphanumeric). There is no standard method for numbering documents, nor is there a standard type face used for such numbers.
Manual Bates stampers use a self-inking mechanism with four to seven numbered wheels. Some stampers allow for consecutive, repeat, duplicate and triplicate numbering.
Self-adhesive labels printed with Bates numbers are common today, as is electronic document discovery (EDD) software that can electronically "stamp" documents stored as computer files by superimposing numbers onto them. The Bates Automatic Numbering-Machine is being increasingly replaced by such software, except in cases where electronic versions of the documents are not available or are not practical to produce.

Cleft of Dimensions Wiki
The Surface of the Cleft is spherical like any normal planet but there are some things that hang in the heavens high above.
It's not certain whether these celestial bodies are truly celestial bodies or whether they are just illusions/constructs/mana spirits. Theoretically, the dimension of the Cleft should extend infinitely into the void, so, at the very least, we have room for any celestial bodies we like. Note: even if the void is infinite, it doesn't mean that the whole thing is filled with stars! Any stars that are in the Cleft are probably either created by the immortals or brought here from other dimensions in the cataclysmic events that created this place.
Note that Final Weapon is somewhere in space, in orbit.
The Cleft has a series of constellations, and the visible constellations vary depending on what time of year it is. Here are our current constellations:
 - North Star, Raphael the Raven
 - The Sword of Mana
 - The Pool of Stars
 - Fortissimo the fallen
 - The Chimes of Aquilon
 - Queen Diana of diamonds
 - Chain of Hope, Sarai's brilliantly shining constellation
The Moon[]
The Cleft also has a moon. The lunar cycle is 27 days. The new moon occurs on the 1st day of the cycle and the full moon occurs on the 14th day. These are hardcoded facts.
Assuming Luna Moon Base is part of the Cleft, the moon must be real enough to be habitable.
For more information, see Time.
The Sun[]
A sun also appears to be in the Cleft's outer space. It works like any regular sun, rising in the east and setting in the west. Solar luminosity is pretty much constant throughout the Cleft, weather aside.

General-purpose machine gun
||This article is incomplete. (July 2011)|
||This article needs additional citations for verification. (October 2007)|
A general-purpose machine gun (GPMG) is a belt-fed weapon used in a variety of roles, from bipodor tripod-mounted infantry support to deployment as a helicopter door gun or a vehicle-mounted support weapon. It can provide fire support for vehicles or infantry from a variety of mounts.
In modern practice, it is an air-cooled medium machine gun, firing rifle cartridges such as the 7.62×51mm NATO, 7.62×54mmR Warsaw pact, or 7.92x57mm Mauser. It is generally operated from a stationary position from either a bipod or tripod, or otherwise mounted on a vehicle, as it is usually too powerful and heavy to be fired effectively on foot from an unsupported standing position or on the move.
The GPMG barrel can be removed and replaced within seconds - in use, the barrel quickly heats up, necessitating its replacement after 400 rounds of continuous fire; once cooled down, the barrel can be reused.
The first general purpose machine gun was proposed by Vladimir Fyodorov in the early 1920. Ten years later the idea resurfaced in Denmark and Czechoslovakia, some time later - in Germany. "In 1934 the Germans adopted the MG 34. The MG 42, that succeeded it at the end of 1942, had better-functioning automatics and was cheaper to manufacture, but neither did the MG-42 meet the requirements of the army, which is evident from the continuous work on its improvement. The rapid attempt to modernize the system in 1945 had no practical significance whatsoever due to the end of WW2." The concept was successful enough to be adopted in many post-WWII armies.
Notable post-WWII examples
- Belgian FN MAG, the most widely used GPMG among NATO and other western armies.
- American M60 (later replaced by the M240 (an FN MAG variant) in US service).
- German MG3, a direct descendant of the MG 42, is still in service with the German Army and others.
- Russian PK/PKM family of multi-purpose machine-guns, widely exported.
- People's Republic of China, the Type 67 and later improved models.
- South African Vektor SS-77.

In a highly connected world eBird is the social media of birders. It is an online database (and now mobile app) where birders can enter observations in real time. It has become a huge resource for birders all over the world! Birders can now go to eBird to find out where certain species are being found, what's being found in their area and look at trends that are occurring in specific bird species' population.
It's not just for birders though. Anyone with a backyard and (hopefully) birds in it can use eBird. Logging what you see in your own backyard on eBird means that anyone in the world can look at your data and learn more about the bird population in your yard and around the world. The data is accessible to anyone around the world and is used to help learn more about bird population changes, diversity and the overall health of our birds.
Using eBird is also fun! When you log the species you've observed on eBird, your observations are saved meaning a comprehensive list is kept for you so you know what birds you've seen and what birds you haven't seen. eBird is also the platform used for global and national bird-watching events such as the Great Backyard Bird Count. With eBird you can learn more about the birds that live around you and around the world!
When you use eBird you are helping to save birds around the world! Please give eBird a try!

By an abelian $\otimes$-category I mean a symmetric monoidal category $(\mathcal{A},\otimes,\mathcal{O})$, such that $\mathcal{A}$ also is an abelian category and for every $M \in \mathcal{A}$ the functor $M \otimes - $ is cocontinuous (i.e. right exact and preserves coproducts; in particular additive). A line bundle is defined as an object $\mathcal{L}$ of $\mathcal{A}$ such that there is some object $\mathcal{L}'$ such that $\mathcal{L} \otimes \mathcal{L}' \cong \mathcal{O}$. An example is the category of (quasi-coherent) modules on a locally ringed space. The line bundles then coincide with the modules which are locally free of rank $1$ (see here).
Now I want to show that in general these line bundles have similar properties as in the case of the module category. For example it's not hard to show that if $\mathcal{L}$ is a line bundle, then it is flat in the sense that $\mathcal{L} \otimes -$ is exact (it is even an automorphism of $\mathcal{A}$ with inverse $\mathcal{L}^{-1} \otimes -$). The isomorphism classes of line bundles yield a group, which may be denoted as $\text{Pic}(\mathcal{A})$.
Question 1. Is there any literature about these abelian $\otimes$-categories which treats them systematically? Perhaps the "usual" definition differs a little from mine, this does not matter.
Question 2. Let $\mathcal{L}$ be a line bundle and $\phi : \mathcal{L} \to \mathcal{L}$ an epimorphism. Does it follow that $\phi$ is an isomorphism?
Question 3. Let $\mathcal{L}$ be a line bundle and assume $\phi : \mathcal{L} \to \mathcal{L}$ is an epimorphism. Does it follow that there is an epimorphism $\psi : \mathcal{L}^{-1} \to \mathcal{L}^{-1}$ such that $\phi \otimes \psi$ corresponds to the identity of $\mathcal{O}$ under the isomorphism $\mathcal{L} \otimes \mathcal{L}^{-1} \cong \mathcal{O}$?
Question 4. Assume we also have a $\lambda$-structure on $\mathcal{A}$ which is compatible with the given data. Is it possible to give a reasonable definition of a locally free object of rank $n$? See also this question.

For questions 1, 2, and 3, it does not seem necessary to require that the monoidal product be symmetric. – André Henriques Nov 23 '10 at 19:41
What about doing algebraic geometry over $\mathcal{A}$ in the sense of Toën and Vaquié arXiv:math/_PHONE_ (published in J. K-theory 3 (2009), 437-500)? This way, you will be able to speak of locally free objects as usual (this might answer questions 1 and 5). Also, the comment of Theo Johnson-Freyd below suggests that the answer to Question 2 is yes: apply his argument to the smallest tensor abelian category generated by $\mathcal{L}$ (which is small). – Denis-Charles Cisinski Nov 27 '10 at 23:36
Could you elaborate what the paper has to do with my question? I don't want to enrich my data with topologies, it should stay homological. Otherwise it's just a trivial translation. Also I'm not sure if the Theorem cited by Theo applies here, does it really give a full faithful exact tensor functor? – Martin Brandenburg Nov 28 '10 at 15:14
The point of Toën and Vaquié is precisely that the monoidal structure itself defines canonically a Zariski topology, as well as a faithully flat topology (so, without any extra data, if you think of your $\mathcal{A}$ as an abstract category of modules over a commutative ring, you will have a lot of the tools you are used to with usual commutative algebra). This idea of doing algebraic geometry over an abelian tensor category was also used by Deligne to study tannakian categories; see the Grothendieck Festschrift vol II, p. 111-195. With Toën and Vaquié, you don't need the abelian structure. – Denis-Charles Cisinski Nov 28 '10 at 22:38
Q2: No, take Z[x]-modules on which x acts injective. Q3: No, since this is Q2 by Steve's answer. Q4: Yes, this will appear in my thesis... – Martin Brandenburg Feb 1 '13 at 13:19
1 Answer 1
Question 2: this does not really depend on line bundles. If $\phi:\mathcal {L\to L}$ is a non-invertible epimorphism, then $\phi\otimes 1:\mathcal{ L\otimes L'\to L\otimes L'}$ is epi, since $-\otimes\mathcal L'$ is exact, and non-invertible, since otherwise $\phi\otimes 1\otimes 1:\mathcal{L\otimes L'\otimes L\to L\otimes L'\otimes L}$ would be invertible. Thus there is a non-invertible epimorphism $\mathcal {O\to O}$.
Question 3: this has the same answer as Question 2. If the answer to Q2 is yes, then we can take $\psi$ to be the identity and get a positive answer to Q3. If the answer to Q2 is no, then (as above) if $\phi:\mathcal{ L\to L}$ is a non-invertible epimorphism, also $\phi\otimes 1:\mathcal{ L\otimes L'\to L\otimes L'}$ is a non-invertible epimorphism. But now if $\psi:\mathcal {L'\to L'}$ is any map, then $\phi\otimes\psi=(1\otimes\psi)\circ(\phi\otimes 1)$ and if this is invertible then $\phi\otimes 1$ is split monic and so invertible (since it is already known to be epi).
share|improve this answer
Q2: Ok this reduces it to the case of maps $\mathcal{O} \to \mathcal{O}$. Are there examples? Q3: If $\phi$ is an isomorphism, then $\phi \otimes L'$ does not have to be the identity! – Martin Brandenburg Nov 23 '10 at 23:21
Q3: you're right, I should have used $\mathcal{(\theta^{-1}\otimes 1_{L'})(1\otimes\phi^{-1}\otimes 1)(\theta\otimes_{L'}}$ for $\psi$, where $\theta:\mathcal{\O\cong L\otimes L'}$. – Steve Lack Nov 24 '10 at 0:05
sorry, try again: $(\theta^{-1}\otimes 1_{L'})(1_{L'}\otimes \phi^{-1}\otimes 1_{L'})(\theta\otimes 1_{L'})$ where $\theta:O\cong L'\otimes L$. (Hope this works, it's tricky without preview facility) – Steve Lack Nov 24 '10 at 0:08
If you are going to find a counterexample to Q2 (i.e. a $\otimes$ category when 1 has a non-invertible epi), you'll have to look pretty far. Most such categories (say, the small ones) embed in R-mod-R for some ring R, and the endomorphisms of 1 in R-mod-R are the center of R, and the only epis are invertible. – Theo Johnson-Freyd Nov 25 '10 at 19:53
_USER_: You quote arxiv.org/abs/math/_PHONE_, right? But there we only have a right exact embedding. – Martin Brandenburg Dec 3 '10 at 14:48

 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

A grapple is an object traditionally consisting of a rope or chain ending with a 'hook'. Grapples are commonly used by adventurers as a way of safely scaling otherwise impassable obstacles such as cliff faces or wide chasms. An important tool in the inventory of any intrepid explorer, the grapple has inevitably found its way into games.
Within gaming, the grapple has many applications, depending on the game in question. In a lot of games, grapples are used in platforming segments to allow a character to access a location that would otherwise be out of their reach. Some games use grapples within combat, sometimes to pull an enemy in close for a melee hit, and other times to steal protective shields and armor from foes in order to expose a weakness. The importance of grapples in gaming is perhaps best illustrated by titles such as Bionic Commando, in which use of the grapple is a key game mechanic.

When it comes to selecting a wooden floor for use within your property it can seem a daunting proposal. So many questions can arise seemingly out of nowhere. These questions can range from what wood type to select, what sheen will best complement the rooms existing décor and which surface will prove most durable over the years to come? V4 Flooring understand that selecting a wooden floor is not always straight forward, due to this we have created a four stage selection process which enables you to easily and effectively identify the wooden floor which matches your requirements and personal tastes.
Selecting A Wooden Floor: Four Easy Steps
1. Choose the right floor for you:
The first stage in selecting a wooden floor is to decide which material you wish to use. When selecting a floor type it is not only the aesthetic appearance which should be taken into account. There are a number of other effects which are equally if not more important, which need to be taken into account. To demonstrate it is important to know whether a particular flooring type is compatible with underfloor heating. Other factors which should be considered are whether the flooring can be resealed if necessary. This is an important factor, if for some reason the flooring needs to be brought up in order to address an unrelated plumbing or electrical problem, boards which can be resealed can be replaced once work is finished. Boards which cannot be resealed on the other hand cannot.
2. Select your preferred grading type:
Once you have selected a flooring type, it is time to consider the type of grading which most appeals. At V4 Flooring we make use of 3 tasteful grading variations. These variations include:
- AB Select/Natural Grade: This grading can feature some light sapwood around the edges of the board. In addition, boards of this grade type may feature some small sound knots and smaller filled knots both of which greatly enhance the natural effect of the grade.
- ABC Mixed Grade: This grading is popular in a number of wood types, most notably Walnut. This grade features a higher variation of grain and wood colour. In addition this grade features a greater number of sound ad filled knots than found in the AB Select/Natural grade type. With this grade type, dark streaks and a number of small, filled cracks may be present.
- CD Rustic Grade: Using more economical timber types provides greater grain and colour variation within the flooring. Flooring of this grade type tends to feature large sound knots and a greater number of filled knots than on other grade types.
3. Choose the right finish type:
A number of finish types are available on wooden flooring. Each of these have their own maintenance requirements. The three finish types which V4 Flooring use include:
- Lacquer: Under this finishing method the top layer of the wooden surface is coated with five individual layers of primer coats. Added to this are at least two additional coats of a UV cured Treffert aluminium oxide lacquer. This method produces a surface which is both hard wearing and also low maintenance.
- Natural Oil: This finish is created with up to four coats of natural WOCA oil. This oil is applied with rollers, each successive layer is buffed into the top layer of the panel. This process not only permeates the grain of the plank but also adds a matt sheen which is then left to cure. The natural oil finish produces the most natural effect of the three finish types.
- UV Oil: The process to create this effect is similar to the one used to create the natural oil finish. Where it differs however is each coat is cured using a UV light. This process produces a slight satin sheen on the surface on the panels.
4. Finally choose the optimum surface:
V4 Concrete make use of a number of different techniques, in order to provide a range of varied surface finishes. Each of these techniques produces a visually different aesthetic effect. The techniques include:
- Brushed: With this technique a steel brush is utilised in order to remove soft grain from the surface of the flooring. This technique greatly enhances the natural beauty of the woods natural grain.
- Hand Scraped: In order to be successful this technique must be undertaken by skilled and experienced craftsmen. The process involves using hand tools in order to scrape out the woods soft grain whilst following the natural contours of the wood.
- Distressed: To achieve this effect a number of techniques are used. These techniques give the wood an aged appearance. The skill of this technique is making the distressed effect look authentic and natural.
- Stained: In order to create this effect the wood panels are stained. The stain is applied with rollers, this is then buffed in order to enable the stain to penetrate the top level of the wood. The panel is then sealed with either oil or lacquer.
- Smoked: With this effect the timber is placed for three days in a drying room. The drying room is filled with ammonia vapour or ‚Äúsmoke‚Äù which causes the woods colour to darken.
- Carbonised: To achieve this effect the timber is baked in a kiln causing the soft grain to be consumed. This causes the wood to blacken and the grain texture becomes exposed.

Background: Groundwater supplies for drinking water are frequently contaminated with low levels of human enteric virus genomes, yet evidence for waterborne disease transmission is lacking.
Objectives: We related quantitative polymerase chain reaction (qPCR)–measured enteric viruses in the tap water of 14 Wisconsin communities supplied by nondisinfected groundwater to acute gastrointestinal illness (AGI) incidence.
Methods: AGI incidence was estimated from health diaries completed weekly by households within each study community during four 12-week periods. Water samples were collected monthly from five to eight households per community. Viruses were measured by qPCR, and infectivity assessed by cell culture. AGI incidence was related to virus measures using Poisson regression with random effects.
Results: Communities and time periods with the highest virus measures had correspondingly high AGI incidence. This association was particularly strong for norovirus genogroup I (NoV-GI) and between adult AGI and enteroviruses when echovirus serotypes predominated. At mean concentrations of 1 and 0.8 genomic copies/L of NoV-GI and enteroviruses, respectively, the AGI incidence rate ratios (i.e., relative risk) increased by 30%. Adenoviruses were common, but tap-water concentrations were low and not positively associated with AGI. The estimated fraction of AGI attributable to tap-water–borne viruses was between 6% and 22%, depending on the virus exposure–AGI incidence model selected, and could have been as high as 63% among children < 5 years of age during the period when NoV-GI was abundant in drinking water.
Conclusions: The majority of groundwater-source public water systems in the United States produce water without disinfection, and our findings suggest that populations served by such systems may be exposed to waterborne viruses and consequent health risks.

Whether you are playing Santa's helper or in a school play craft your own Christmas elf hat out of felt or velvet fabric.
Felt or velvet fabric
Needle and thread or hot glue gun
The first step is to make a basic hat pattern from paper. Draw and cut a triangle with a base length and height of 13 inches.
For an adult-sized hat, increase the base and height measurements to 14 inches.
Tie a pencil to a string and stretch the string taut from the apex (or tip) of the triangle until the tip of the pencil touches the midpoint of the triangle's base. While keeping the string taut, draw an arc spanning the two opposite sides of the triangle.
Before drawing the arc, you may find it helpful to tape your paper triangle to the table and the string to the apex of the triangle.
Cut out the pattern. You will have something that looks like a slice of pie.
Obtain a large sheet (at least 22 x 14 inches) of green or red felt. If you want a soft or droopy hat, use thin felt or a soft-type fabric such as velvet.
*In case you don't have a large enough sheet of felt or fabric, you can use 2 smaller sheets. Each sheet should be able to accommodate the hat pattern you made.
Align one side of your hat pattern along the folded edge of the fabric. Trace the pattern onto the fabric.
*If you are using two smaller felt or fabric sheets, trace the hat pattern onto each sheet.
While keeping the fabric folded, cut along the hat outline.
For those who are working with two smaller sheets, cut out the hat outline on each sheet.
Join the straight edges of the folded fabric by stitching them together or by gluing them together with a hot glue gun.
*When working with two smaller sheets, you will have to sew or glue the pair of hat cut-outs together along their two straight sides.
When the glue dries, turn the hat inside-out so that the stitches or the glued edges are concealed inside. You will also notice that you now have a cone-shaped fabric hat.
If you used green felt for the hat, obtain red felt for the zigzag lining at the base of the hat, or vice-versa. We have a template that you can print, cut out and trace repeatedly (approximately 3 times) to make a long band that can go around the entire base of the hat.
Cut out the entire zigzag band. If your felt sheet is not long enough, you can make shorter pieces or glue/sew them together to make a longer band.
Glue (use hot glue gun) or stitch the zigzag band at the base of the hat.
Sew or glue a jingle bell at the tip of your Christmas elf hat.
You may further decorate your elf hat by gluing small pompoms or tiny bells at the tips of the zigzag band.
Have fun wearing your Christmas elf hat!

text: Using an IR thermometer, there are two ways to go about building a thermographic camera. The first uses a pan and tilt head. Scan lines are emulated, as a computer controls panning from left to right, taking a temperature sample from each step. Vertical resolution is accomplished by tilting. Another method uses a web cam attached to the thermometer. The thermometer's laser pointer is captured with temperature annotations, as the computer records the field of view. We think the best outcome can be found with a combination of both methods. The video embedded below demonstrates the results. This would be a good addition to the Autonomous paintball sentry.

Neuronal Re-Differentiation in Older Age
German citizens are amongst the oldest in the world. Due to insufficient knowledge about the neuronal mechanisms underlying age-related cognitive and sensorimotor decline, an increasing number of people in Germany suffer from age-related loss of autonomous living. In the current project, we propose a fresh approach to this topic.
We will target central neuronal mechanisms that have in recent years been connected to age-related cognitive and sensorimotor decline. We will use cutting-edge methodology, including structural and functional imaging at 7 Tesla MRI, to explore architectural changes in primary sensory brain areas that have in animal research been related to neuronal de-differentiation.
Besides gaining experimental knowledge of striking importance, the proposed project will also aim to implement novel scanning protocols and analysis pipelines at the DZNE Magdeburg. This will be performed in close cooperation with established research partners at the Max Planck Institute for Human Cognitive and Brain Sciences in Leipzig, and UCL in London.


Hanapepe massacre

Hanapepe massacre
Date September 9, 1924
Location Hanapepe, Hawaii
Goals $2 daily wage
8 hour day
Parties to the civil conflict
Striking Filipino sugar workers
Lead figures
Jack Butler
Deaths: 16 killed
Arrests: 101
Deaths: 4
The Hanapēpē Massacre (also called the Battle of Hanapēpē since both sides were armed) happened on September 9, 1924. Toward the end of a long-lasting strike of Filipino sugar workers on Kauaʻi, Hawaiʻi, local police shot dead nine strikers and fatally wounded seven, strikers shot and stabbed three sheriffs to death and fatally wounded one; a total of 20 people died. The massacre brought an end to armed protests in Hawaii.
By the 1920s, the sugar plantation owners in Hawaiʻi had become disillusioned with both Japanese and Filipino workers. They spent the next few years trying to get the U.S. Congress to relax the Chinese Exclusion Act so that they could bring in new Chinese workers. Congress prevented the importation of Chinese labor.[1]
But organized labor in the 1920s' U.S. mainland supported the Congress in this action, so that for a while it looked as though militant unionism on the sugar plantations was dead. To oppose organized labor, the Hawaiian Territorial Legislature passed the Criminal Syndicalism Law of 1919, Anarchistic Publications law of 1921, and the Anti-Picketing Law of 1923.
These laws, with penalties of up to 10 years in prison, increased the discontent of the workers. The Filipinos, who were rapidly becoming the dominant plantation labor force, had deep-seated grievances: as the latest immigrants they were treated most poorly. Although the planters had claimed there was a labor shortage and they were actively recruiting workers from the Philippines, they wanted only illiterate workers and turned back any arrivals who could read or write, as many as one in six.
Strikes and Massacre[edit]
By 1922 Filipino labor activist Pablo Manlapit had organized a new Filipino Higher Wage Movement which numbered some 13,000 members. In April 1924, it called for a strike on the island of Kauaʻi, demanding $2 a day in wages and reduction of the workday to 8 hours. As they had previously, the plantation owners used armed forces, the National Guard, and strike breakers paid a higher wage than the strikers demanded. Again workers were turned out of their homes. Propaganda was distributed to whip up racism. Spying and infiltration of the strikers' ranks was acknowledged by Jack Butler, executive head of the Hawaiian Sugar Planters' Association.
Strike leaders were arrested in attempts to disrupt workers' solidarity, and people were bribed to testify against them. On September 9, 1924, outraged strikers seized two strike breakers at Hanapēpē, Kauaʻi and prevented them from going to work. The police, armed with clubs and guns, came to union headquarters to rescue them. Filipino strikers were armed only with homemade weapons and knives.
The Associated Press flashed the story of what followed across the United States in the following words: Honolulu. - Twenty persons dead, unnumbered injured lying in hospital, officers under orders to shoot strikers as they approached, distracted widows with children tracking from jails to hospitals and morgues in search of missing strikers - this was the aftermath of a clash between cane strikers and workers on the McBryde plantation, Tuesday at Hanapepe, island of Kauai. The dead included sixteen Filipinos and four policemen.[citation needed]
After the massacre police rounded up all male protesters they could find, and a total of 101 Filipino men were arrested. 76 were brought to trial,[2] and of these 60 received four-year jail sentences. Pablo Manlapit was charged with subornation of perjury and was sentenced to two to ten years in prison.[3] The Hawaiʻi Hochi claimed that he had been railroaded into prison, a victim of framed-up evidence, perjured testimony, racial prejudice and class hatred. Shortly thereafter, he was paroled on condition that he leave Hawaiʻi. After eight months the strike disintegrated.
The Federationist, the official publication of the American Federation of Labor, reported that in 1924 the ten leading sugar companies listed on the New York Stock Exchange paid dividends averaging 17 percent. From 1913 to 1923, the eleven leading sugar companies paid cash dividends of 172.45 percent, and most of them issued large stock dividends.
After the 1924 strike, the labor movement in Hawaiʻi dwindled, but did not die, and discontent among the workers rarely surfaced again. Pablo Manlapit, who had been imprisoned and exiled, returned to the islands in 1932 and started a new labor organization, this time hoping to include other ethnic groups. But the time was not ripe in the Depression years. There were small nuisance strikes in 1933 that made no headway and involved mostly Filipinos. Protests since the massacre have discouraged carrying guns at demonstrations.

Background: There has been no study conducted about the effect of autosuggestion on quality of life for geriatric patients. Our aim was to evaluate the efficacy of autosuggestion for geriatric patients' quality of life and its impact on psycho-neuro-endocrine-immune pathway. Methods: Sixty geriatric patients aged ≥60 years in a ward were randomly assigned to either receive autosuggestion or not. Autosuggestion was recorded in a tape to be heard daily for 30 days. Both groups received the standard medical therapy. Primary outcome was quality of life by COOP chart. Secondary outcomes were serum cortisol level, interleukin-2, interleukin-6, interferon-γ, and N-acetylaspartate/creatine ratio in limbic/paralimbic system by magnetic resonance spectroscopy. The study was single blinded due to the nature of the intervention studied. Results: Out of 60 subjects, 51 finished the study. The autosuggestion group reported better scores than the control one for quality of life, COOP chart 1.95 vs. 2.22 (95% CI, p = 0.02). There were increments of serum cortisol (p = 0.03) and interleukin-6 in the autosuggestion group (p = 0.04). Interleukin-2, interferon-γ, and N-acetylaspartate/creatine ratio in prefrontal cortex showed a tendency to increase in the autosuggestion groups. Conclusion: Autosuggestion is associated with improvement of geriatrics' quality of life, serum cortisol level, and adaptive immunity. There is a better trend for neuroplasticity in prefrontal cortex in the autosuggestion group.

Robot to help assemble IKEA furniture
The Nordic furniture maker IKEA offers large furniture at a relatively low price instead of being able to assemble it on their own. However, even if it is designed to be easily assembled by beginners, it is quite difficult to assemble many parts while wrestling with the schematic. A research team at the USC Viterbi School of Engineering has developed a robot that helps assemble IKEA furniture.
In the video, a woman is assembling an Ikea bookshelf, and the robot, watching this, grabs the parts to be used next and gently pushes it out when the panel assembly is finished. When you start reassembling, the robot will already start selecting the parts it needs next.
The characteristic of this robot is that it learns human tastes by observing humans assembling them. The robot analyzes the video of 20 people assembling the bookshelf in advance, learns the behavior pattern, predicts which part the person in front of you wants to assemble next, and hand over the parts.
The IKEA furniture assembly robot was already announced in 2018. The robot announced in 2018 assembled IKEA chairs fully automatically, but this time the robot was developed with the theme of cooperation between humans and robots.
Carrying heavy parts is advantageous for robots, but delicate tasks such as tightening small screws or finely adjusting parts are suitable for humans. In order to set various sequences for human behavior, the robot learns and predicts these sequences to help assemble furniture. The research team expects to apply this technology to helper robots such as meal support and preparation in the future. Related information can be found here.

Is a Self Retracting Lifeline the same thing as a Yoyo?
Yo-yo, self-retracting lifeline, self-retracting lanyard, retracts, self-retracting devices, retractable lifelines…. The names for these lifesavers create a long and ever changing list depending on what region you're from and what industry you work in. What you really need to know is that, yes, they are all referring to the same device. A lifeline that pays out, retracts, causes deceleration, and arrests as a fall occurs is classified as a retractable lifeline.
What is a Retractable Lifeline?
Yo-yos are a type of lanyard that allow the user to freely move around the workspace as the lifeline cable extends out of the housing and, in turn, coils back up inside the shell as the worker gets closer to the unit again to keep the cable taut. This automatic feature eliminates the trip hazard commonly presented by a traditional lanyard.
How Does a Retract Work?
Self-retracting lifelines are devices that are connected to a worker's body harness. If a fall occurs, the deceleration device can detect the fall and engages an automatic break to stop the lifeline from moving, thus arresting the fall. The braking mechanism is similar to that of a seatbelt because if you yank on the lifeline, it engages the brake, but if you smoothly pull the line in and out, it creates a fluid movement.
Overhead and Horizontal Use of Self-Retracting Lifelines
Retractable lifelines can certainly be used in a number of applications and positions. For use overhead, the retractable almost instantly arrests a fall and drastically minimizes fall distance. Along with limiting fall distance, when the unit is anchored directly over the worker's head, the possibility of a dangerous swing fall is significantly lowered.
Using SRL's horizontally presents two very important factors to be weary of, leading edges and fall clearance. If you are using the retractable lifeline in conjunction with a horizontal lifeline or have the potential to encounter a leading edge, you must use a specifically engineered leading edge SRL to ensure the cable won't snap if a fall occurs. The other notable factor to look out for is calculating fall clearance. When the user is anchored off at foot-level and using a self-retracting device, it will take longer for the unit to detect a fall. Because of this, you must carefully consider the fall clearance needed before you choose an anchorage position.
OSHA and ANSI SRL Standards
OSHA has created standards for the personal fall arrest system to regulate equipment to comply with the arresting forces that the human body can withstand. In OSHA standard 1910.140(d)(1)(i) it reads that the PFAS should, "Limit the maximum arresting force on the employee to 1,800 pounds (8 kN)". The deceleration device (SRL or shock absorbing lanyard) satisfies this regulation.
The Occupational Safety and Health Administration (OSHA) standard 1910.140 states that "Self-retracting lifeline/lanyard means a deceleration device containing a drum-wound line that can be slowly extracted from, or retracted onto, the drum under slight tension during normal movement by the employee. At the onset of a fall, the device automatically locks the drum and arrests the fall."
ANSI furthers the regulations for retracts and states that the manufacturer of your SRL should have the deceleration information clearly marked on the front or rear label of the lifeline housing.
 1. Connectors – Connectors are any device that connects your body harness to an anchor point (e.g. shock absorbing lanyards, lifelines, self-retracting lifelines (SRLs), and positioning devices). Account for potential fall distance when choosing a type of connecting device. Adding/using shock absorbing lanyards reduces the fall force impact on your body.
 1. Deceleration Device – Any mechanism that serves to dissipate energy during a fall. Suspension trauma can occur in as little as 15 minutes; do you have a rescue plan?
 Have a fall protection question?

This session introduces pupils to some of the amazing ancient wax seals in our collection. The aim of the workshop is to give pupils an understanding of how seals were made, how and why they were used, and what the images used on them mean.
For the first activity, we look at royal seals from the time of Edward the Confessor up to the present day. Pupils identify different elements of the designs and compare how they have changed and developed over the last thousand years. Pupils also have a close look at some of the seals belonging to Tudor kings and queens to see what particular impression each one tried to create about themselves on their seal.
For the second activity, we look at personal seals that belonged to barons, knights, ladies, craftsmen, religious houses and ordinary people in medieval and Tudor times. Pupils work out why each person chose the design they did for their seal, and discuss how this can help us understand people in the past. Finally, pupils get to try designing their own seal on paper using the knowledge and ideas they have gained during the workshop to create images that are appropriate to their life and interests.
