Simulation of Interstitial Atom Diffusion in FCC Metals with Point Defects
This work is devoted to simulation of interstitial atom diffusion in fcc metals with point defects. We used the molecular static and the Monte Carlo methods. An activation barrier set for different configurations of the carbon–vacancy complexes is simulated by the method of the molecular static (MS). Then we calculate atom jump rates for these configurations. The simulation of the carbon and vacancy migration in an fcc metal is realized on the basis of obtained atom jump rates by using the Monte-Carlo (MC) method. In particular, the calculations were made for the system of the nickel-carbon. In the result of that interstitial atom diffusion coefficient has been obtained at different temperatures.

Mobile Benchmarks
As gRPC has become a better and faster RPC framework, we've consistently gotten the question, "How much faster is gRPC?" We already have comprehensive server-side benchmarks, but we don't have mobile benchmarks. Benchmarking a client is a bit different than benchmarking a server. We care more about things such as latency and request size and less about things like queries per second (QPS) and number of concurrent threads. Thus we built an Android app in order to quantify these factors and provide solid numbers behind them.
Specifically what we want to benchmark is client side protobuf vs. JSON serialization/deserialization and gRPC vs. a RESTful HTTP JSON service. For the serialization benchmarks, we want to measure the size of messages and speed at which we serialize and deserialize. For the RPC benchmarks, we want to measure the latency of end-to-end requests and packet size.
Protobuf vs. JSON
In order to benchmark protobuf and JSON, we ran serializations and deserializations over and over on randomly generated protos, which can be seen here. These protos varied quite a bit in size and complexity, from just a few bytes to over 100kb. JSON equivalents were created and then also benchmarked. For the protobuf messages, we had three main methods of serializing and deserializing: simply using a byte array, CodedOutputStream/CodedInputStream which is protobuf's own implementation of input and output streams, and Java's ByteArrayOutputStream and ByteArrayInputStream. For JSON we used org.json's JSONObject. This only had one method to serialize and deserialize, toString() and new JSONObject(), respectively.
In order to keep benchmarks as accurate as possible, we wrapped the code to be benchmarked in an interface and simply looped it for a set number of iterations. This way we discounted any time spent checking the system time.
interface Action {
 void execute();
// Sample benchmark of multiplication
Action a = new Action() {
 public void execute() {
 int x = 1000 * 123456;
Before running a benchmark, we ran a warmup in order to clean out any erratic behaviour by the JVM, and then calculated the number of iterations needed to run for a set time (10 seconds in the protobuf vs. JSON case). To do this, we started with 1 iteration, measured the time it took for that run, and compared it to a minimum sample time (2 seconds in our case). If the number of iterations took long enough, we estimated the number of iterations needed to run for 10 seconds by doing some math. Otherwise, we multiplied the number of iterations by 2 and repeated.
// This can be found in benchmark()
int iterations = 1;
// Time action simply reports the time it takes to run a certain action for that number of iterations
long elapsed = timeAction(action, iterations);
while (elapsed < MIN_SAMPLE_TIME_MS) {
 iterations *= 2;
 elapsed = timeAction(action, iterations);
// Estimate number of iterations to run for 10 seconds
iterations = (int) ((TARGET_TIME_MS / (double) elapsed) * iterations);
Benchmarks were run on protobuf, JSON, and gzipped JSON.
We found that regardless of the serialization/deserialization method used for protobuf, it was consistently about 3x faster for serializing than JSON. For deserialization, JSON is actually a bit faster for small messages (<1kb), around 1.5x, but for larger messages (>15kb) protobuf is 2x faster. For gzipped JSON, protobuf is well over 5x faster in serialization, regardless of size. For deserialization, both are about the same at small messages, but protobuf is about 3x faster for larger messages. Results can be explored in more depth and replicated in the README.
To benchmark RPC calls, we want to measure end-to-end latency and bandwidth. To do this, we ping pong with a server for 60 seconds, using the same message each time, and measure the latency and message size. The message consists of some fields for the server to read, and a payload of bytes. We compared gRPC's unary call to a simple RESTful HTTP JSON service. The gRPC benchmark creates a channel, and starts a unary call that repeats when it recieves a response until 60 seconds have passed. The response contains a proto with the same payload sent.
Similarly for the HTTP JSON benchmarks, it sends a POST request to the server with an equivalent JSON object, and the server sends back a JSON object with the same payload.
// This can be found in doUnaryCalls()
// Make stub to send unary call
final BenchmarkServiceStub stub = BenchmarkServiceGrpc.newStub(channel);
stub.unaryCall(request, new StreamObserver() {
 long lastCall = System.nanoTime();
 // Do nothing on next
 public void onNext(SimpleResponse value) {
 public void onError(Throwable t) {
 Status status = Status.fromThrowable(t);
 System.err.println("Encountered an error in unaryCall. Status is " + status);
 // Repeat if time isn't reached
 public void onCompleted() {
 long now = System.nanoTime();
 // Record the latencies in microseconds
 histogram.recordValue((now - lastCall) / 1000);
 lastCall = now;
 Context prevCtx = Context.ROOT.attach();
 try {
 if (endTime > now) {
 stub.unaryCall(request, this);
 } else {
 } finally {
Both HttpUrlConnection and the OkHttp library were used.
Only gRPC's unary calls were benchmarked against HTTP, since streaming calls were over 2x faster than the unary calls. Moreover, HTTP has no equivalent of streaming, which is an HTTP/2 specific feature.
In terms of latency, gRPC is 5x-10x faster up to the 95th percentile, with averages of around 2 milliseconds for an end-to-end request. For bandwidth, gRPC is about 3x faster for small requests (_PHONE_ byte payload), and consistently 2x faster for large requests (10kb-100kb payload).

In evolutionary game theory, it is typical to model organisms as having a base fitness that is modified slightly by the game interaction. The ratio of the game effect versus the base fitness determines the strength of selection, with weak selection meaning the game modifies overall fitness only slightly, and strong selection meaning that the game payoff is a big part of the overall fitness of the organism.
Most analytic models like to assume weak selection because it allows the authors to Taylor expand the selection function and linearize it by dropping terms that are higher order in the stength of selection. However, it is unclear that results derived for weak selection would necessarily hold under strong selection. Are there mathematical (or computational) models where weak and strong selection produce qualitatively different results? If not, is there an argument as to why weak and strong selection should produce the same results?
I've also seen this discussion come up outside of evolutionary game theory, in a more general biological setting. In particular, with respect to inclusive fitness. The take away message I got was that in the regime of weak selection relatedness means what you expect it to mean, but for strong selection the concept becomes very slippery and counter-intuitive. What does inclusive fitness theory tell us about going from weak to strong selection? Again, I prefer arguments supported by clean mathematical or computational models over ones based on intuition and words alone.

I haven't had time to look closely at it, but you might find this paper interesting: Wu et al. 2010. Universality of weak selection. ArXiv. It seems like they try to bend the rules and study differences between models. – fileunderwater Jan 9 at 21:33

1 Answer 1
It has been shown that predictions based on weak selection can be different from that on strong selection. In fact, for rare mutations, each strategy has stationary distribution at the mutation selection equilibrium. The rank of the component depicts the relative prevalence of the available strategies. Yet the rank of the components of this distribution can change with the selection intensity. Thus results obtained under weak selection can not generally carry over to strong selection.

Catfish can be caught a variety of ways, such as with a line and hook, bait traps, and cast nets. Baiting hooks with live fish is effective for catching larger catfish, as they feed primarily on other fish. Oily fish such as shad, herring and suckers are ideal.Continue Reading
Carp, chubs, goldeyes and sunfish can also be used as bait for larger catfish. When using hooks, leaving the barb of the hook exposed is the most effective way to catch biting fish as a catfish is not smart enough to recognize a hook. With the barb concealed, setting the hook requires it to pierce through the rest of the bait before it can catch a lip, making it less likely to penetrate the catfish's mouth. Piercing the back, lips or the narrow portion of the tail is ideal for baitfish. Using other baits, such as cut fish, crayfish or worms, pierce the surface once or twice, with the hook point exposed.
Catfish can be caught year round, as many varieties do not go inactive even during the winter. During periods of the summer, catfish start to spawn, and both males and females become inactive. They spend much of their time on the bottom of lakes and rivers, but are not exclusively bottom feeders. Bobbers can effectively allow baits to drift across active areas for catfish, such as near river dams, around junctions of two rivers, around fallen trees in deep pools or stump fields near the edge of a channel.
While it is commonplace to fish at night for catfish, the fish is not nocturnal and can be caught during any time of day. The period of time prior to a storm is a good time to catch catfish, as they become more active just before a change in weather, and can continue to be active until storms pass.Learn more about Water Sports & Activities

Joint attention on actions: acquiring verbs in ostensive and non-ostensive contexts.
Two studies of verb learning are reported. The focus of both studies was on children in their second year of life learning verbs in various pragmatic contexts. Of particular interest was the comparison of ostensive contexts--in which word and referent were simultaneously present in the child's perceptual field--to non-ostensive contexts. In a naturalistic study of 24 children at 1;3 and 1;9, it was found that mothers modelled verbs for their children most often BEFORE the referent action actually occurred. Over 60% of maternal verbs were used to refer to actions that mothers wished children to perform or that they were anticipating their performing (IMPENDING actions). Some verbs were also used to refer to current actions (ONGOING actions) or actions that had just been completed (COMPLETED actions). Children responded with comprehension most often to impending models. Impending and completed models, but not ongoing models, were correlated with children's verb vocabularies at 1;9. The second study was a lexical training study of 48 two-year-olds. Children learned to produce a novel verb best when it was modelled in the impending condition. They learned to comprehend it equally well in the impending and completed conditions. Children showed no signs of superior learning in the ostensive (ongoing) learning context. Results of the two studies are discussed in terms of the different learning processes involved in acquiring nouns and verbs, and, more broadly, in terms of a social-pragmatic view of language acquisition in which the ostensive teaching paradigm is but one of many contexts in which children learn to establish a joint attentional focus with mature language users.

Secret DNR report details warming dangers in SC
COLUMBIA — South Carolina's wildlife agency gathered a team of scientists more than a year ago to study what could happen if temperatures in the state continue to warm, but have never released their report.
A draft of the committee's findings determined that if temperatures rise in the South by 9 degrees as projected by some over the next 70 years, South Carolina would see more beach flooding and invasion of non-native species such as piranha and Asian swamp eels, according to a draft of the report obtained by The State of Columbia.
One scientist involved in the initial work on the report for the Department of Natural Resources said there were political concerns whether readers of the report would accept that global warming was happening and was a danger.
"There were concerns about the political nature of it," Barry Beasley said.
But the new DNR director said the report needs more work before it is released. The agency also is busy with other environmental matters such as port expansion and a massive gold mine planned for Lancaster County, DNR Director Alvin Taylor said.
The group had 18 members, including seven PhDs, a climatologist and at least five other agency biologists.
"Scientists in all divisions of the DNR are concerned over the potential impacts of climate change on natural resources," the draft report says. "DNR recognizes climate change as a real phenomenon, grounded in numerous scientific studies, and DNR recognizes that thoughtful and careful planning is needed in order to protect the natural resources of the Palmetto State.

Good Citizenship
April 24, 2019

tonnes of NO₂ reduced annually
There's an old saying that goes, "Every good citizen adds to the strength of our nation." But these days, good citizenship can also mean adding to the strength of our planet. CF industries makes fertilizer that allows farmers to grow more crops on less land–which means that, as a company, they help prevent the deforestation that releases harmful carbon into the air. They're good corporate citizens.
But there's a hitch: the process of making that fertilizer releases nitrous oxide (N₂O), a greenhouse gas that warms the planet over 300 times faster than CO₂. So, though there are no government regulations requiring them to do so—and most companies don't—CF Industries voluntarily installed sophisticated new catalytic technology that breaks down N₂O into its environmentally harmless components, nitrogen and oxygen. Now, with your generous support, their Yazoo City, Mississippi, plant prevents 200,000 tonnes of N₂O every year from warming the planet. That's the equivalent of preserving 1,000 acres of untouched Amazon rainforest!
Farming practices that nearly double the world's production of food combined with good corporate citizenship that, year by year, improves the air we breathe? Those are the kind of efforts that truly add to the strength of our planet. So, good citizen, thank you for your support!

Cunjevoi live on rocky shores in Australia. They are found on reefs and rock platforms and wharf pylons. Cunjevoi are found in waters up to 12 m deep.
Cunjevoi eat plankton. Cunjevoi take sea water in through one of the openings and remove all plankton from it. The plankton is moved to the stomach. Unwanted water is passed out through a second opening.
People fishing use Cunjevoi for bait. Orange Tritons eat Cunjevoi.
Cunjevoi are sometimes called sea squirts because they can spray a jet of seawater out of their body when squeezed. Cunjevoi belong to a group of animals called Tunicates.

Wildlife along the Trail
With its panoramic views and low, alpine vegetation, the Pinnell Mountain Trail offers ample opportunities for observing wildlife. For information on how to improve your chances of observing wildlife, see our wildlife viewing tips.
Caribou (Rangifer tarandus). Until the 1960s the ridges of the Pinnell Mountain Trail lay on the main migration route of the Fortymile Caribou Herd, whose calving grounds were then located in the White Mountains. Travelers and biologists reported seeing hundreds of thousands of caribou crossing the Steese Highway near Eagle Summit. The herd no longer moves to the White Mountains for calving, but portions of the herd may visit the area in fall or winter. Small groups of caribou seen here during the summer are more likely resident members of the smaller White Mountains Caribou Herd, which numbers about 700 animals.
Caribou are unique in the deer family in that both females and males have antlers. Males shed their antlers after rut (breeding) while some pregnant females carry their antlers all winter and shed them in late spring. Caribou eat mostly lichens in winter, but their more varied summer diet includes willows, scrub birch, grasses, and sedges such as cottongrass. During annual migrations they travel between calving grounds and winter feeding areas.
Marmots. Hoary marmots (Marmota caligata) live in rock outcrops and rubble fields, including those around the North Fork Shelter Cabin. Marmots are social animals that live in colonies. When startled, they usually sound a loud whistle. Some marmots near the shelter cabins have already become habituated to people. Please do not make the situation worse by feeding them.
Pika. The northern or collared pika (Ochotona collaris) is a short-eared relative of the rabbit. Listen for its shrill chirp around rock slides or talus slopes. Consider yourself lucky if you see these highly alert animals.
Wolves, grizzly bears, and moose are occasionally seen along the trail.

floor exerciseArticle Free Pass
floor exercise, gymnastics event in which movements are performed on the floor in an area 12 metres (40 feet) square. This area is covered by some type of cloth or mat, usually with some cushioning. No other apparatus is used. Men's routines are 50 to 70 seconds in duration. The type of exercise required is a series of movements combining elements of flexibility, strength, jumps, holding of poses, and balance, as well as other maneuvers. The whole routine must be performed with rhythm and harmony, and the gymnast must move in different directions, using a major portion of the allotted area.
The exercise usually starts and finishes with a series of tumbling movements, such as a handspring or a cartwheel with a half-turn (roundoff), continuing with handsprings and somersaults (in the air), either backward or forward. Between start and finish, balances are held on one leg, handstands are achieved by placing the hands on the floor and kicking to a standing position, and movements resembling ballet, tumbling movements, and jumps are interposed.
The women's event is similar to the men's, except that it is performed to music and lasts 70 to 90 seconds. The floor exercise was introduced as an individual Olympic medal sport for men in 1936 and for women in 1952.
What made you want to look up "floor exercise"? Please share what surprised you most...

hot money business definition
Funds that are controlled by investors who seek high short-term yields when the funds are likely to be reinvested somewhere else at any time. Some financial institutions attract hot money by offering above-average yields on certificates of deposit. However, if the rate is lowered, the funds are likely to be lost to another institution or investment.Case Study
Although an improbable target for currency speculators, tiny Iceland (population approximately 300,000) gained fame as a world depository for hot money shortly after the country lifted currency exchange controls in the late 1990s. Funds seeking the krona's high interest rates flooded into the island country from around the world, much of it representing borrowed money obtained in low-interest Japan. The inflows helped produce a booming economy with a strong currency, soaring stock market, and skyrocketing housing prices. The economic boom was accompanied by inflation, causing the central bank to raise interest rates to 11.5% by mid-2006. The increase in interest rates also resulted from the government's concern that hot money would begin flowing back out of Iceland as interest rates started rising in Europe, Japan, and the United States. A rapid outflow of hot money would depress the country's currency, increase the cost of imported goods, and cause a downward spiral in asset values.

This Is America?: The Sixties in Lawrence, Kansas
Publisher: Palgrave Macmillan | ISBN: _PHONE_ | edition 2004 | PDF | 320 pages | 1,02 mb
In his first book, Monhollon (history, Hood Coll.) examines Lawrence, KS, during the 1960s. Being the home of the University of Kansas guaranteed that Lawrence would see the same type of student activism that other universities experienced during the decade. However, the population of Lawrence itself was socially and politically conservative. Townsfolk supported the Vietnam War and were unsympathetic to the Civil Rights, antiwar, and feminist movements. Confrontations between student activists and the local authorities grew during the late 1960s, climaxing in July 1970 when police shot two men. These deaths led to weeks of shootings and arson, which forced the governor to send in the National Guard to patrol the city. Monhollon uses interviews, newspaper articles, and other archival sources to present this story. Richly detailed and well written, his book gives an excellent account of how a Midwestern town was affected by a troubled period of American history.

Dolphin Pregnancy Is a Drag, Literally
A bottlenose dolphin.
CREDIT: Chris Johnson – earthOCEAN
The extreme physical changes that come during pregnancy may be most evident in humans, but they plague other animals as well. New research shows that pregnant dolphins are so hefty the increased drag on the body makes them swim slower.
"They have this huge body and that creates a large frontal surface area and that drag is going to pull at them," study researcher Shawn Noren, of the University of California, at Santa Cruz, told LiveScience. "Swim performance is lower as well."
It's possible that this extra effort to swim fast could have an impact on the species' survival. If the pregnant dolphins can't escape predators or keep up with their group when chased by tuna fishermen, it could explain why the population isn't rebounding as quickly as expected, Noren said. (Groups of dolphins and groups of tuna tend to live in close proximity, so tuna fishermen chase down dolphins to get to the tuna that usually live below them.)
Dolphins in action
Noren filmed two pregnant dolphins at Dolphin Quest in Hawaii. They were nearly full term. She compared these videos with video taken two years after the pregnancy and found that not only did the larger fully pregnant females produce more drag as they swam through the water, their swimming technique was also altered.
An analysis showed that by having a greater surface area due to their pregnant bellies, which meant more water for the dolphins to push out of their way as they swam, the drag on their bodies increased by about 50 percent compared with their svelte, non-pregnant state.
"When this animal is not pregnant it can swim exactly twice as fast and get the same drag," Noren said.
Because of where the baby dolphin sits (near the mama's tail) during development, the mothers also didn't have as much flexibility at near full-term. They couldn't flip their tails up and down as far as they could after giving birth, so they compensated by flipping their tails about 14 percent more often. [Infographic: How Long Are Animals Pregnant?]
"That whole second half of the animal's body is what the dolphins use to swim, and that fetus is sitting back there toward the back part of the tail," Noren said. "We measured the same animals after birth [of their baby], and they were moving their tail flukes higher when they weren't pregnant than when they were."
These weighed-down mamas might have more trouble outrunning predators (or tuna fishermen) in the wild. Noren notes that their wild predators, which include sharks and some whales, can reach speeds faster than these pregnant dolphins and so might be able to overtake them in a chase.
During these chases, fleeing either aquatic or human predators, young, sick or pregnant dolphins may lose their group, which, Noren said, "could explain why the population isn't recoveringat the expected rate."
This kind of pregnancy drag is likely present in every animal. Birds and land animals (and even insects) need to fight against gravity to keep moving, and as they grow larger this gets more difficult.
"Every animal has shown reduced performance [during pregnancy] and becomes quite sedentary," Noren said. Not many studies have been able to show exactly how much of a drag pregnancy can be.
The study was published Nov. 24 in the Journal of Experimental Biology.

To clean the blue protective film off new tires, use a rubber cleaner or mild soap with a brush or cloth. Gently scrub the surface until the blue residue lifts away.
New tires often come with a noticeable blue coating, a manufacturing byproduct that protects the rubber. This distinctive hue is actually a release agent or preservative applied during production to keep the tires in pristine condition until they reach the consumer.
As an expert in SEO content creation, this guide is tailored to answer one of the common questions tire buyers have: "How do I remove the bluish protective layer from my new tires? " This concise introduction provides a clear step-by-step assistance while optimizing for search engines, ensuring that tire enthusiasts and car owners find the information they need efficiently and without hassle. With the correct tire cleaning method, your wheels will be ready to hit the road with a clean, fresh appearance.
Introduction To Tire Blooming
Tire blooming, a term unfamiliar to many, refers to a common phenomenon owners notice with new tires. This process is not merely cosmetic; it holds significance for maintaining the tires' integrity. Understanding and addressing tire blooming is crucial for both the appearance and longevity of your new tires.
Defining Tire Blooming And Its Causes
Tire blooming occurs when tires start to look dull and lose their black, glossy appearance. This is often mistaken for dirt or wear, but in reality, it's a reaction that takes place on the tire's surface. There are specific causes behind this blooming:
- Antiozonants Reaction: Tires contain protective compounds that migrate to the surface and react with ozone in the air.
- UV Light Exposure: Ultraviolet light from the sun accelerates the degradation of tire compounds.
- Manufacturing Process: The use of certain mold release agents can contribute to the blooming effect.
Why It's Important To Remove The Blue Film On New Tires
When tires leave the factory, they often have a blue protective film that guards against oxidation. This layer is essential to tire preservation before they are sold. However, once you have the tires mounted, it's crucial to remove this blue film for several reasons:
- Ensures Peak Performance: Proper tire traction is crucial, and having a clean tire surface is part of it.
- Maintains Appearance: Clean, bloom-free tires enhance the look of your vehicle.
- Avoids Long-term Damage: Leaving the film on could shorten tire lifespan by trapping heat and moisture.
Preparing To Clean New Tires
Welcome to the essential guide on making your new tires shine! When you purchase new tires, they often come with a blue protective film. This film prevents damage during storage and shipment. But it's not the best look for hitting the road. We'll take you through each step to ensure your tires are spotless and ready to roll.Gathering the Necessary Supplies
Gathering The Necessary Supplies
Effective cleaning starts with having the right tools. Here's what you'll need:
- Tire cleaner – A cleaner designed for tire care.
- Soft-bristled brush – To scrub without harming your tires' surface.
- Microfiber cloth – For a smooth finish.
- Bucket – To mix water and cleaner if necessary.
- Gloves – To protect your hands during cleaning.
Safety Precautions Before Starting The Cleaning Process
Safety is paramount. Before you start, take these steps:
- Ensure the cleaning area is well-ventilated.
- Wear gloves to protect your skin from cleaners.
- Keep cleaners away from children and pets.
- Follow the cleaner's instructions carefully.
Step-by-step Guide To Cleaning The Blue Off New Tires
Welcome to the ultimate guide for making your new tires shine! New tires come with a blue protective film that keeps them fresh. But before you hit the road, let's get them looking their best by removing the blue coating. This step-by-step process will ensure a thorough clean without damaging your tires.
Initial Rinsing: Removing Loose Dirt And Debris
Begin with a gentle rinse. It's vital to remove any loose dirt that could scratch the rubber during cleaning. Use a garden hose with moderate pressure, making sure you get around the entire tire surface.
Applying The Cleaning Solution: What Products To Use
Select a mild soap or tire cleaner. Harsh chemicals can damage the tires. Mix with warm water in a bucket. Look for cleaners that state "safe for all tires" to ensure compatibility.
Scrubbing Techniques: How To Effectively Remove The Blue Film
Use a soft-bristle brush to apply the cleaning solution. Brush in a circular motion, focusing on areas with the blue film. Gentle strokes are key – aim to remove the film without being rough on the tire.
Final Rinsing And Drying: Ensuring No Residue Is Left Behind
After scrubbing, rinse the tires thoroughly. Ensure all cleaner is washed off to prevent residue. To dry, use a microfiber towel or chamois to absorb water without scratching. Leave them spotless and dry before you drive.
Preventive Measures And Tire Maintenance
Brand-new tires gleam with a distinctive blue coating, a factory-applied protective layer. But keeping tires clean post-purchase involves more than a simple wash. Good habits and preventive care ensure tires not only look fresh but also perform better and last longer. Start protecting and maintaining tires right from day one with these useful tips.
Protective Products To Keep New Tires Looking Clean
Dress your tires in the right attire. The right products keep tires looking their best. Tire protectants play a vital role. They create a barrier against road grime and UV rays.
- Water-based protectants: Ideal for a natural look and rubber nourishment.
- Silicone-based protectants: Offers a glossy finish and extra durability.
Always apply protectants as instructed. Let them dry completely. This avoids attracting dirt or debris.
Routine Maintenance Tips To Prevent Tire Blooming
|Gentle wash with mild soap and water
|Apply tire protectant
|Professional tire inspection
Following a consistent cleaning regimen keeps tires in pristine condition. Avoid harsh chemicals which can cause rubber degradation, leading to tire blooming – a brown discoloration.
Common Mistakes To Avoid In Tire Care
Remember, tire care is straightforward if you know the pitfalls. Here's what not to do:
- Using harsh cleaners: They strip away natural oils and lead to cracking.
- Spraying protectant on tread: This can reduce grip and affect safety.
- Ignoring tire pressure: Too high or low pressure wears tires out unevenly.
Stick to manufacturer recommendations. Regularly check pressure levels. This ensures optimal tire health and performance.

Gregarines on a Diet: The Effects of Host Starvation on Gregarina confusa Janovy et al., 2007 (Apicomplexa: Eugregarinida) in Tribolium destructor Uyttenboogaart, 1933 (Coleoptera: Tenebrionidae) Larvae
Date of this Version
This study was designed to explore the nutritional relationship between Gregarina confusa (Apicomplexa: Eugregarinida) parasites and its coleopteran host, Tribolium destructor, by measuring the cytoplasmic density of gregarines in continuously fed larvae, starved larvae, and larvae refed after starvation. Cultures were maintained in a standard media (whole wheat flour:commercial wheat germ:yeast [30:10:1]). Larvae from control and experimental groups were dissected daily for three days then allowed to feed or starve for an additional three days. On day 6, the remaining experimental larvae were divided and placed into two groups; one group remained starved while larvae from the second group were fed a WheatiesR flake. Photographs were taken of the parasites daily and analyzed using ScionImage™. Gregarines from starved larvae were significantly longer and skinnier than those from fed controls, and there was also a significant difference between gregarine deutomerite cytoplasmic densities. Parasites from refed larvae regained cytoplasmic density within 24 hr and showed morphological similarities to those from fed larvae. This study shows that the Tribolium destructor–Gregarina confusa relationship can be manipulated easily through alterations of host diet and thus is an excellent model for use in the study of chemical relationships between parasites and their hosts.

The Landég factor describes the response of an atomic energy level to an external perturbation by a uniform and constant magnetic field. In the case of many-electron systems, the leading term is given by the interaction μ B(L- +2S- )•B-, where L- and S- are the orbital and spin angular momentum operators, respectively, summed over all electrons. For helium, a long-standing experimental-theoretical discrepancy for P states motivates a re-evaluation of the higher order terms which follow from relativistic quantum theory and quantum electrodynamics (QED). The tensor structure of relativistic corrections involves scalar, vector, and symmetric and antisymmetric tensor components. We perform a tensorial reduction of these operators in a Cartesian basis, using an approach which allows us to separate the internal atomic from the external degrees of freedom (magnetic field) right from the start of the calculation. The evaluation proceeds in a Cartesian basis of helium eigenstates, using a weighted sum over the magnetic projections. For the relativistic corrections, this leads to a verification of previous results obtained using the Wigner-Eckhart theorem. The same method, applied to the radiative correction (Bethe logarithm term) leads to a spin-dependent correction, which is different for singlet versus triplet P states. Theoretical predictions are given for singlet and triplet 2P and triplet 3P states and compared to experimental results where available.

The religious dances (cham) form an important part of the religious rituals of the Monpa people. During the Torgya Festival, the dances are performed with great sanctity and spiritual quest, by selected Monks of the Tawang Monastery as a part of the Torgya rituals which go on for three days.Before going into details about the actual cham, a mention of the outfits of the dancers needs to be made. The most important object of the dancer's attire is the mask (bak). The masks are carved out of wood and are painted in different colours. They are often double the size of a human face. The costumes used in the cham are mostly made of brocade and silk. The outfit of a dancer representing a deity of higher rank usually consists of a gown (phodka) with long, broad sleeves and a poncho-like tippet (stod le). Some dancers wear a circular breastplate called melongbearing in its center, the 'seed' syllable (sa bon) of the deity, which the dancer personifies. The weapons and other objects which the dancers carry in their hands are the characteristic attributes which Buddhist iconography assigns to a particular God or Goddess. The common objects carried by the dancers in their hands are the skull cup (bandha),damaru, vajra(dorjee), dagger (phurpa), sword (raldri), club in the shape of a mummified corpse (thodthrom), bell (drill bu) or a flag.
Another important component of the chamis the orchestra. The orchestra players are attired in the usual monks' dress. The musical instruments used by the orchestra are the same instruments used in normal religious ceremonies, such as long trumpets (dungchen), clarinet (gyaling), conch shells (dungkar), damaru, drums (dha) and cymbals (silnyen and bubcha). Their beats indicate the rhythm of the dance.
A total of 22 different kinds of Cham are performed during the festival some of which are described as under:
1. Pha cham
In the early mornings of the three days of festival, a dancer in fully ordained monk's dress performs the Phacham by wearing a boar's mask (Pha=boar; cham=dance). This dance is performed in order to prepare the ground for performance of cham by pacifying the malice of the gods and spirits so that perfect conditions could be created for performance.
2. Shanag cham
Shanag cham is performed by twelve dancers wearing phodka, a kind of richly embroidered kaftan reaching to the ankles and pang kheb, a colorful richly embroidered apron. The dancers wear a black, broad-brimmed hat from which the dance derived its name Shanag(black hat). The dancers personify Tantric priests. After executing the cham for some time, four dancers representing Dharmaraja Kalarupa and his consort, Chamundi accompanied by their attendants appear on the scene dancing solemnly. They are greeted by the Abbot of the Tawang Monastery by offering scarves from the balcony above. After the dance is over, the Abbot; senior lamas, all the above dancers and the procession of people proceed towards the southern gate of the monastery to participate in the Torgya rites.
3. Gon-Nyin cham
This cham is performed by eleven dancers each holding a ritual bell in one hand and damaru in the other. They represent dakinis who are the protectors of the Buddha Dharma. Gon-Nyin cham is generally performed when an important religious venture is to be undertaken like the construction of a monastery or when a holy statue is to be installed and consecrated. It is performed to distract the attention of the demons who create obstacles to the advancement of the Buddhist doctrine. It is believed that the demons get so engrossed in watching this dance that they forget to create obstacles in the work.
4. Lham Tsoktor
Wearing fearful masks and dressed magnificently, a group of twelve dancers representing the retinue of Palden Lhamo (Sri Devi) perform this cham signifying the clearance of ground for her appearance. A masked dancer representing Palden Lhamo comes out from the main temple dancing solemnly. Her attendants escort her. Before entering the dance arena, the Abbot of Tawang Monastery offers scarves to Palden Lhamo and her attendants from the balcony above. Reaching the dancing square, she is ushered to the throne arranged for her. Seir-Kyem (libation) is then offered to her by some senior monks. This dance is performed to invoke the blessing of Palden Lhamo, the principal guardian deity of Tawang Monastery.
5. Zam Cham
Wearing fierce looking masks, this dance is performed by two dancers holding small flags in their right hands and skull cup in the left hands. It symbolizes the taking possession and safeguarding the ground which is to be used for performance of sacred dances.
6. Dung Cham
Dung-cham is performed for the prosperity of all sentient beings. This cham is performed by wearing mask of different animal figures. The dancers represent the retinue of Chamsing, a protective deity.
7. Gelong Cham
For peace and prosperity in the world, twelve dancers dressed in ceremonial monks' robes perform this cham.Apart from the above sacred dances, many shabbily dressed clowns play their part as interludes, besides entertaining the public with mimes, they also teach moral lessons.

A new smart basketball can measure the arc and backspin on a shot, or the speed and force of a player's dribbling. "Now, when coaches say, 'Your left hand is weak,' they can prove it," Mark Davisson, president of InfoMotion Sports Technologies, told Design News. "The ball doesn't lie."
Known as the 94Fifty, the smart basketball employs a combination of nine sensors -- including accelerometers, gyroscopes, and a magnetometer -- to gather 6,000 pieces of data per second and send them to a processor for analysis. Designed by engineers at Infomotion, it incorporates the sensors, along with a digital signal processor, a Bluetooth communication system-on-chip (SOC), and an inductive power charging antenna inside the lining of the ball.

InfoMotion's smart basketball gathers information about shooting or dribbling, and then sends it wirelessly to a smartphone or tablet computer.
(Source: InfoMotion Sports Technologies)
When a player shoots or dribbles the 94Fifty, onboard "event recognition" algorithms take inertial data from the sensors and determine what's happening. Accelerometers provide force information, gyroscopes supply angular rate data, and the magnetometer determines magnetic north and provides directional information.
Taking all the data together, the ball is then able to tell how much force and control players have while dribbling, how much arc or backspin they have on a shot, or how long it takes for them to catch and shoot. After gathering the information, it sends it via Bluetooth wireless to a smartphone or tablet computer, so players can view data seconds after it's been measured.
"We have an app that visualizes the information in real time," Kevin King, vice president of engineering for InfoMotion, told us. "You can take a shot, and as soon as the ball hits the floor afterward, the information is there."
InfoMotion initially developed the technology about two years ago, selling the basketball along with a laptop computer to teams for more than $2,000. Users included high schools, colleges, and at least one pro team. Over time, however, the company's engineering staff was able to incorporate the software and hardware inside the ball and cut the price. A consumer ball, for use by an individual, is expected to be available by October for $295.
"We realized there was a market for kids to take the ball into the driveway and do their own drills without a coach," King told us.
InfoMotion teamed with Texas Instruments on the development of the consumer ball. TI engineers provided a C5000 digital signal processor (DSP), a Bluetooth/Bluetooth Low Energy communications SOC, and a Qi-compliant wireless power technology system that enables the ball's onboard battery to be charged without plugs or wires.
"We had to miniaturize the sensing and processing technology, then figure out how to get it inside the ball," King said. TI helped InfoMotion engineers put the technology on a postage stamp-sized printed circuit board that fits inside the lining of the ball. "The last thing we added was the wireless charging capability, so the ball could be sealed and the technology would be seamless to the customer."
King told Design News that the company's engineers used a DSP chip, instead of a conventional microcontroller (MCU), because the DSPs they looked at could execute four operations per clock cycle, compared to just one for an MCU. "It's all about number crunching," he said. "To do the same thing with a microcontroller would have taken a processor that was four times faster."
With all of the electronics technology incorporated on the small PC board, InfoMotion's team then designed an enclosure that would fit just under the skin of the ball but still be able to protect it from shock and vibration. "Our goal was to make it so you can't tell we did anything to the ball," King said.
The company is considering other sports applications for the electronics platform, including soccer balls and kettle bells for health clubs. "If someone comes to us and says, 'We'd like to put this in a bowling ball,' we would use the exact same electronics platform," Davisson said. "Our core competence is writing the algorithms for different kinds of applications."


Devil's curve
From Wikipedia, the free encyclopedia
Jump to: navigation, search
Devil's curve for a = 0.8 and b = 1.
Devil's curve with a ranging from 0 to 1 and b = 1 (with the curve colour going from blue to red).
In geometry, a Devil's curve is a curve defined in the Cartesian plane by an equation of the form
y^2 (y^2 - a^2) = x^2 (x^2 - b^2).
Devil's curves were studied heavily by Gabriel Cramer.
The name comes from the shape its central lemniscate takes when graphed. The shape is named after the juggling game diabolo, which involves two sticks, a string, and a spinning prop in the likeness of the lemniscate. The confusion is the result of the Italian word diavolo meaning 'devil'.[1]

How to Get Mold Smell Out of Dresser Drawers
Mel Frank
Dressers are a perfect way to store clothing, keeping it safely out of sight yet on hand and quickly accessible. The problem is that these drawers are dark, typically sealed off when closed, and can quickly develop moisture that leads to the development of a musty, moldy odor. To remove the odor, simply treat the drawers with a quick odor removal solution.
Get rid of mold smell with ease.
 1. Place a small dish of baking soda in each drawer. The baking soda is a natural odor absorbant that will also draw any moisture out of the drawers. Let the baking soda sit overnight.
 2. Fill a spray bottle with white vinegar. The vinegar is a deodorizing agent and will also kill any mold or mildew growth that is causing the odor.
 3. Spray the vinegar solution into all of the drawers.
 4. Keep the drawers open, and allow the drawers to air out overnight.
 5. Repeat if needed if all odor has not dissipated.

Excessive iodine can lead to goiters. However, the relationship between the water iodine concentration (WIC) and goiter rate (GR) is unclear. This study aims to explore the factors that influence children's GR in areas with high WIC and analyse the threshold value of the GR increase associated with the WIC. According to the monitoring of the areas with high WIC in China in 2018–2020, a total of 54 050 children in eight high water iodine provinces were chosen. Drinking water, urine and edible salt samples of children were collected. The thyroid volume (Tvol) was measured. A generalised additive model (GAM) was used to analyse the relationship between the WIC and GR in children. Among the 54 050 children in areas with high WIC, the overall GR was 3·34 %, the median of water iodine concentration was 127·0 µg/l, the median of urinary iodine concentration was 318 µg/l and the non-iodised salt coverage rate (NISCR) was 63·51 %. According to the GAM analysis results, water iodine and urinary iodine are factors that influence the Tvol and GR, while the NISCR affects only the GR. When the WIC was more than 420 µg/l or the urinary iodine concentration was more than 800 µg/l, the GR increased rapidly. When the NISCR reached more than 85 %, the GR was the lowest. Thus, in areas with high WIC, WIC more than 420 µg/l may increase the risk of goiter, and the NISCR should be increased to over 85 % to avoid goiters in children.
Global warming increases the risk of pests and weeds before wintering, and decreases the grain yield of winter wheat. Therefore, the sowing date should be delayed properly. But the variety of winter wheat that can adapt to late sowing remains unclear. Here, we selected two winter wheat cultivars and evaluated four sowing date treatments on 1 October (early sowing), 8 (normal sowing), 15 (late sowing) and 22 (latest sowing) over two wheat-growing seasons at the experimental Station of Shandong Agricultural University (35°96′N, 117°06′E), Daiyue District, Taian, Shandong, China. We examined the effects of sowing date on a few traits, and found that, compared with normal sowing, though spike number decreased, grain yield was maintained above 9300 kg/ha under late and latest sowing. The main reason was that the more accumulated N from jointing to anthesis resulted in a higher grain number per spike. The higher net photosynthetic rate after anthesis, through optimizing N distribution in the canopy and increasing Rubisco content of flag leaves, improved dry matter accumulation rate and contribution ratio of vegetative organs, ultimately, ensured consistent grain weight. The grain yield of high-tillering winter wheat cultivars decreased from 9370 to 8346 kg/ha. The main reason was that spike number, accumulated N from jointing to anthesis and net photosynthetic rate decreased significantly, which reduced the dry matter accumulation rate, and only satisfied less grains to achieve consistent grain weight. Therefore, low-tillering winter wheat cultivars are more adaptable to late sowing, and can reduce the harm of global warming.
This paper explores the relationships among positive and negative work reflection during leisure time, psychological capital, and radical and incremental creativity. We collected data from 500 dyads of employees and their direct supervisors, and employed the structural equation model to test our research hypotheses. The results reveal that positive work reflection during leisure time is positively related to radical and incremental creativity, while negative work reflection during leisure time is negatively related to the two types of creativity. Our findings also suggest that psychological capital mediates the effects of positive and negative work reflection during leisure time on radical and incremental creativity.
This study aimed to identify the important capacities that were most urgently needed during emergency response and factors associated with the Centers for Disease Control and Prevention (CDC) professionals' field coping-capacity for public health emergency.
Professional workers (N = 1854) from 40 CDC institutions were chosen using the stratified cluster random sampling method in all 13 municipalities of Heilongjiang Province, China. Descriptive analysis and multivariate logistic regression were used.
Of 10 key capacities, the 3 that were most urgently needed during emergency response fieldwork as identified by respondents were crisis communication capacity, personal protection capacity, and laboratory detection capacity. Overall, 38.1% of respondents self-rated as "poor" on their coping-capacity. The logistic regression found that proficiency in emergency preparedness planning, more practical experiences in emergency response, effectiveness in training and drills, a higher education level, and a higher professional position were significantly associated with the individual's field coping-capacity.
This study identified CDC professionals' most urgent capacity need and the obstructive factors and highlighted the importance of enhancing the capacity in crisis communication, personal protection, and laboratory detection. Intervention should be targeted at sufficient fund, formalized, and effective emergency training and drills, more operational technical guidance, and all-around supervision and evaluation.
We report a new pulsed chemical vapor deposition (PCVD) process to deposit nickel (Ni) and nickel carbide (Ni3Cx) thin films, using bis(1,4-di-tert-butyl-1,3-diazabutadienyl)nickel(II) precursor and either H2 gas or H2 plasma as the coreactant, at a temperature from 140 to 250 °C. All the PCVD films are fairly pure with low levels of N and O impurities. The films deposited with H2 gas at ≤200 °C are faced centered cubic-phase Ni metal films with low C content; but at ≥220 °C, another phase of rhombohedral Ni3C is formed and the C content increases. However, when H2 plasma is used, the films are always in rhombohedral Ni3C phase for the entire temperature range.
Several epidemiological studies have been performed to evaluate the association of fruit and vegetable consumption with risk of the metabolic syndrome (MetS), but the results remain controversial. Thus, we conducted a systematic meta-analysis to assess the associations of fruit or/and vegetable consumption with risk of MetS, separately.
We searched PubMed, EMBASE and Web of Science databases up to July 2017 for relevant available articles. Pooled OR with 95 % CI were calculated with the fixedor random-effects model.
A total of nine studies for fruit consumption, nine studies for vegetable consumption and seven studies for fruit and vegetable consumption were identified as eligible for the present meta-analysis. The pooled OR (95 % CI) of MetS for the highest v. lowest category were 0·87 (0·82, 0·92; I2=46·7 %) for fruit consumption, 0·85 (0·80, 0·91; I2=0·0 %) for vegetable consumption and 0·76 (0·62, 0·93; I2=83·5 %) for fruit and vegetable consumption. In subgroup analyses stratified by continent where the study was conducted, the inverse association of fruit consumption (0·86 (0·77, 0·96)) and vegetable consumption (0·86 (0·80, 0·92)) with risk of MetS remained significant in Asia. There was no evidence of small-study effect.
Our meta-analysis indicates that fruit or/and vegetable consumption may be inversely associated with risk of MetS. It suggests that people should consume more fruits and vegetables to decrease the risk of MetS.
Early life is considered a critical period for determining long-term metabolic health. Postnatal over-nutrition may alter glucocorticoid (GC) metabolism and increase the risk of developing obesity and metabolic disorders in adulthood. Our aim was to assess the effects of the dose and timing of a fish oil diet on obesity and the expression of GC-activated enzyme 11β-hydroxysteroid dehydrogenase type 1 (HSD1) in postnatal overfed rats. Litter sizes were adjusted to three (small litter (SL)) or ten (normal litter) rats on postnatal day 3 to induce overfeeding or normal feeding. The SL rats were divided into three groups after weaning: high-dose fish oil (HFO), low-dose fish oil (LFO) and standard-diet groups. After 10 weeks, the HFO diet reduced body weight gain (16 %, P<0·05), improved glucose intolerance and decreased hyperlipa

The U.S. Department of Education released a report of state high school graduation rates, which for the first time includes apples-to-apples comparisons among most states. Each state used to determine its own graduation rate; now states are moving toward a common method of measurement.
As Schools of Thought reported earlier, graduation rates for some states have dropped not because students are failing more often, but because the math has changed. The USDOE points this out in a press release on its website: "While 26 states reported lower graduation rates and 24 states reported unchanged or increased rates under the new metric, these changes should not be viewed as measures of progress but rather as a more accurate snapshot." The new data is based on a "four year cohort graduation rate," which also accounts for students who drop out or do not earn a regular high school diploma.
(Read "The new graduation rates" for an explanation of these metrics.)
Across the United States, the range of state graduation rates is between Nevada's 62 percent and Iowa's 88 percent. The District of Columbia's rate is lower than that of any state, at 59 percent. Some states, including Kentucky and Idaho, are not using the new method and were not included in the data released by USDOE.
Looking at the data itself another picture emerges -- a gap between whites and blacks still exists, but an even wider gap persists between general graduation rates and the graduation rates of children with disabilities and limited English proficiency students. For these subgroups, graduation rates in many states are below 50 percent, and sometimes even below 30 percent.


Factors affecting quality of life in people with multiple sclerosis
 - Fatigue and depression have a clinically significant impact on the health-related quality of life (HRQoL) of people with multiple sclerosis (PwMS).
Why this matters
 - Physical and psychological factors associated with MS can have a serious impact on HRQoL.
 - It is important to identify which factors have a greater negative effect on HRQoL in order to target treatment and manage long-term disease.


At a Glance
Sustainability is integrated into a luxury resort's infrastructure and new construction, creating a unique, eco-friendly vacation destination while improving the local ecology and reducing maintenance costs.
Project Description
The redevelopment of the Dorado Beach Resort, a high-end community of over 300 homes and several hotel buildings slated to be renovated or razed, presented an opportunity to improve the property's functionality, reduce operating costs, and build upon the legacy of the resort's original builder, conservationist Laurence S. Rockefeller.
As a member of the design team, Biohabitats examined the potential to enhance the project by implementing a wide range of environmental strategies. These strategies would not only create a more environmentally sensitive travel destination, but transform the way visitors think about sustainable infrastructure.
Biohabitats assessed opportunities for new and ugraded infrastructure plans, including two new hotels and a renovated environmental education center. Biohabitats identified opportunities to improve system functionality, reduce operational and maintenance costs, and provide watershed protection. Concepts were detailed in an Environmental Opportunities Memorandum, which also outlined key principles and tools needed to integrate the concepts into the redevelopment. Key principles included energy efficient design, site drainage improvements, and sustainable wastewater and stormwater management.
Given that water was one of the most valuable long-term resources available to the site, Biohabitats recommended a Water Balance that would consider: beneficial reuse and stormwater harvesting; season-specific and landscape-specific water use; precision; integrated green design; integrated phasing; and flexibility. Biohabitats also provided recommendations for alternative wastewater management and irrigation practices, drainage infrastructure plans and landscape management practices. Specific recommendations included implementation of rain harvesting systems, rain gardens, naturalized swales, and vegetated strips.

word similarity measure
by karey3341 (Initiate)
on Feb 27, 2009 at 16:18 UTC ( #746935=perlquestion: print w/ replies, xml ) Need Help??
karey3341 has asked for the wisdom of the Perl Monks concerning the following question:
If my data looks like this:
word 1: 100 101 101 102 102 102 106 106
word 2: 101 104 106 110 113 129 131 148
word 3: 101 153 175 180 381
word 4: 106 110 113 122 131 137 142 148
word 5: 120 165 169
Where word 1,2,3,4,5 represent different words, numbers represent a list of paper those words have been used as keywords.
How can I calculate similarity between these words?

 Do you know the words, or are they unknown to you?
 Do you assume that, because two words appeared in the same paper, they must be identical or similar in some way?
 What do you mean by 'keywords', and 'papers'? Do they have the same meaning as in scientific research, where 'paper' is a scientific article and 'keyword' is a research subject, organism of interest, or method?
Re: word similarity measure
by kennethk (Monsignor) on Feb 27, 2009 at 16:33 UTC
 Ignoring subtleties about how you may have developed your keyword->index mapping, the easiest way to measure the similarity would be to generate a hash with your word identifiers as keys and then brute force a similarity array. Something like:
 _USER_ = (); for $i_word (1.. $_TAG_) { for $j_word (0.. $i_word-1) { $count[$i_word][$j_word] = 0; foreach (keys %{$paper{$i_word}}) { if (exists $paper{$j_word}{$_} { $count[$i_word][$j_word]++; } } } }
 If you aren't familiar with lists of lists, take a gander at perllol.
Re: word similarity measure
by Old_Gray_Bear (Bishop) on Feb 27, 2009 at 16:56 UTC
 You need to define what you mean by "similarity".
 At first glance words 1, 2. and 4 are'similar' since they each have the same number of sub-components. A second glance reveals that words 1, 2, and 3 are'similar' - they each contain '101'. And words 2 and 4 are'similar', they are the only words that contain 148 and 131.
 I suspect that once you have defined your terms, you will be able to write a function that takes two words and returns the degree of'similarity' between them. Once you have all of the pair-wise ratings computed, sort() will let you rank the papers from most alike to least.
 This sounds like the kind of problem a plagiarism detector is designed for.
 I Go Back to Sleep, Now.
 If, in fact, that is what the OP is after, s/he may benefit from looking at the nodes mentioned here: Re: Finding plagarized content.
 Update: I rather think, OTOH, that the OP may be looking for something more like Ted Pedersen's SenseClusters (more)...

- Rain Riding 101
- Be Smooth. The limited traction available on wet roads demands subtlety whith throttle and brake application, this is most crucial when the bike is leaned over.
- Evaluate Available Traction. Obviously, the amount of traction a road surface will provide changes, as it becomes wet, the amount of degradation will vary from one road surface to another. Be especially careful when transitioning from one type of pavement to another. Additionally, debris on the road (leaves, pine needles, mud, etc.) will have an even more dramatic reduction in grip.
- Rain Riding With Bald Tires Is Like Poking The Reaper With A Pointy Stick. A tire's tread is only there to channel water away, without this you hydroplane. Another point to keep in mind is that temperatures are generally lower during the rainy season in the bay area which will combine with the water to extend the time needed to get your tires up to the correct operating temperature.
- Keep Warm And Dry. Rain riding takes an enormous amount of concentration, try to eliminate any distractions. Not only is it miserable to ride when sopping wet, it's hard to stay focused on the road when the first rivulet of icy water hits your crotch.
- If You Have Abs, Use It! Anti lock brakes allow you to ride harder with less drama in the wet. Many people have ridden their bikes for years without ever engaging the ABS feature. We always stress the importance of periodically using the ABS to familiarize yourself with the unique sensations that accompany its activation. Additionally, you can gradually increase rear brake pressure as you approach a turn and use the point of activation to estimate available traction. With or without ABS, allow for increased stopping distances when initiating your braking.
- Free Standing Water On The Roadway. Don't laugh, we have encountered it on more that one shop ride. The danger here is not so much from a loss of traction, but from drowning the bike. The susceptibility to this varies from model to model. It's best to ascertain the depth of the water and see if it rises above the point where air enters your machine and only make an attempt if it is below this. One caveat here, once you have entered the water, you have reached the point of no return...do not back off the throttle.
- Other Hazards. Some areas/situations to be aware of: Painted lines, manhole covers and buttered Teflon have roughly equal coefficients of friction-look out for them when turning. Avoid the center of the lane at intersections and tollbooths, cars will drop oil there when stopping. Gas stations and the exits of car washes can be treacherous due to oil and soap scum accumulations. Most pundits agree that the first 15-30 min. of rain are the most treacherous because all the oil gets lifted off the road and goes into solution (this may be specious, but it couldn't hurt to be cautious). Finally, many car drivers have difficulty driving in the rain, some drive the way the normally do without regard to the decreased stopping distances. Be ever vigilant to the changing patterns of traffic in the wet.
Further notes on the chalk board:
Tires: Traction = Pressure/temperature/profile/tread depth --- a wet weather tire needs plenty of tread, plenty of sipes, an even, rounded profile.
Suspension: - if you have a choice, set softer than you would set for high speed dry weather riding.
Technique: - Smoothness is everything! Riding in the rain is fun, it does not have to be scary, and it builds skill rapidly.
Rider: - You will be happy in the rain if you are warm, dry and confident!
- Gore-Tex Combi Suits
- Rainsuits over leathers or not waterproof gear
- Trashbags with holes cut for arms and head, plus lots of duct tape.
- Gore-Tex Gloves (Held, Olympia, Triumph, etc.)
- Glove covers - work for short time, but water leaks around cuffs.
- Motocross gloves and electric grips. Hands are wet but water is warm. (Wrinkly fingers but warm hands.)
- Gore-Tex Boots
- Gore-Tex socks inside riding boots (boots get wet; feet stay dry).
- Totes or similar overboots. (Rubber booties for over regular boots.)
- Electric vests & grips are wonderful in wet, cold weather.
- Fog or driving lights make you more visible to other traffic.
- High intensity bulbs or driving lights help you to see better.
"I think riding in the rain is the most fun kind of riding, and I learn the most about riding techniques when I ride in storms and fog."

The invisible force. The all too familiar companion on your Journey.
Its presence is all but guaranteed when you make notable changes in your life. I wrote about 15 signs you may be in the Decline Stage in a recent post. When you feel the decline, you usually have an idea of what you can do to fix it. Resistance enters when you try to act on those ideas. It finds a way to slow you down; it encourages you to delay and talks you out of taking action.
Why does resistance smash your positive intentions?
If I could give you a rock-solid-take-it-to-the-bank answer – I would. Unfortunately, people have tried to figure this out for decades. It is a complex issue with no single answer. What I can offer is the following 5 strategies. While not foolproof, they give you a chance for fighting the demons within.
5 Strategies for Combating Resistance
1. Embrace the Fear: You don't want to fail. Nor do you want to look foolish. You certainly don't want to disappoint or fall short of your desires. All of those "fears" (rationale or irrationale) contribute to building resistance. Most of your fears are either irrational or future based. They aren't real or current. Embrace them; accept them. Fear is real and normal. The trick is not giving it enough power to slow you down!
2. Forgive and Begin Again: When you allow resistance to win, it is frustrating and self-defeating. Common reactions are to quit trying or stop fighting. You beat yourself up and start negative self-talk: "I knew I couldn't do this." Self abuse keeps you down and out of the game. Net/Net – resistance wins. Instead – let it go. Forgive. Give yourself a break. Watch a Rocky movie if you need to, but forgive, forget and climb back on the horse!
3. Stay Uncomfortable: When you resist, you know it. Your subconscious sends guilt your way and nagging feelings of disappointment. Left alone – you learn to live with the disappointment or shortcomings to the point it doesn't bother you any more. The psychobabble suggests you habituate to the ineffective behavior. In short – "the lack of progress becomes okay." That is dangerous. Make yourself uncomfortable again. Get your inner voice working. Keep the pressure on and the blinders off!
4. Start Something: Progress defeats resistance every time. Stop thinking in terms of "completion" and start thinking about "action." Most touchdowns are a series of first downs. Start thinking in "10-yard" increments. Do anything to get out of the mire and into an action mode. Victory is doing something.
5. Reward Progress: When you beat resistance, even for the moment, reward your self. This doesn't mean go buy a new car or a steak dinner every time you do something. It means – take a moment to pat your self on the back and say "good job – you beat it today." It is often a life-long battle so get used to celebrating the little victories along the way.
Remember, to live deliberately takes effort. Slipping into the default is not an option. As you move the needle and grow – resistance shows up and starts to push back. Start implementing these practices today.
Growth is not a given. It is hard. However, even if you take three steps forward and two steps back – you are still advancing! That's the name of the game. So go on a hunt for resistance – watch for it, identify it and then beat it with these strategies!

This article reviews the potential of Niklas Luhmann's autopoiesis as a contribution to organization theory. We consider organization theory to consist of three epistemological foundations, which we label equilibrium-based theory, process-based theory and recursivity-based theory. We review critically Luhmann's autopoietic theory in relation to each of these three foundations. We suggest that whereas it deviates radically from equilibrium-based theory and deviates significantly from process-based theory, it holds potential in its complementarity with Giddens's structuration theory in providing a promising basis for recursivity-based organization theory.

DF2014:Armor stand
From Dwarf Fortress Wiki
(Redirected from Armor stand)
Jump to navigation Jump to search
This article is about the current version of DF.
Armor Stand
Materials Workshops Labors
Armor stands are a type of furniture. Much like the weapon rack, the armor stand can be used to create a barracks. After being built (b-a), you may define the barracks dimensions (b-a, then +-). It can also be placed in a noble's room to appease them.
When used in a barracks designated for individual and squad equipment, dwarves will prefer to store their armor on stands instead of stockpiles. Doing so in concert with weapon racks will allow you to create centralized armories for your military.
Armor stands do not block dwarf movement.
Stockpile storage always takes priority over furniture, making armor stands all but useless for their practical purpose.

English lesbian, gay and bisexual teens first consider their sexuality at 13 years old, but don't tell anyone else until they are on average two years older.
Four out of five young people tell their friends first and three quarters say that they needed emotional support to come out.
The findings, published today (15 February), are part of an interim report of Metro's Youth Chances project, a five year social study of over 6,000 LGBT youth and their needs.
The study also found that the great majority (80%) of respondents to the Youth Chances survey who identified as lesbian or gay, bisexual or questioning said the first person they told they were gay was a friend.
Nearly three quarters (70%) of respondents to the survey who identified as lesbian or gay, bisexual or questioning said they needed emotional support from someone when they came out.
Commenting on the results, Dan Baker, Metro Youth Chances Project Manager, said: 'These findings reveal some key milestones for young people coming out in the 21st century.
'It is a measure of the progress of LGBT visibility and equality that over half of young people in this generation have come out by the age of 16.
'All the more important is that parents and the wider family, friends, schools, colleges, youth organisations and health services recognise that the majority of young people coming out are saying they need emotional support at this time.'
Metro's Youth Chances will continue collecting responses right up until 21 March when it will begin in depth analysis of what support is most effective for young people.
Anyone aged 16 to 25 years old can complete the survey (including heterosexual young people) by clicking on this link. Everyone submitting their answers will be entered into a prize draw to win £500.


extension.
Enables AltiVec language extension as defined in the Motorola AltiVec Technology Programming Interface Manual (PIM). This option is similar in effect to -maltivec, but there are some differences. For example, -mpim-altivec disables inlining of functions containing AltiVec instructions as well as inline vectorization of memset and memcopy.
Adds AltiVec ABI extensions to the current ABI.
Disables AltiVec ABI extensions for the current ABI.
Disables the effect of -mpim-altivec.
Disables the warning of the deprecated long keyword in AltiVec data types.
Disables AltiVec language extension.
-arch ppc970 -arch pp64
Compile for the PowerPC 970 (aka G5) processor, and assemble only 64-bit instructions.
-mcpu=970 -mcpu=G5
Enables the use of G5-specific instructions.
This will force a runtime check to determine which CPU is present and will allow code to run on the G3, G4, or G5, regardless of which CPU was used to compile the code. Exercise caution if you use this and G5-specific features at the same time.
When used in combination with -mcpu=970, -mtune=970, and -force_cpusubtype_ALL, the G5's support for native 64-bit long-long is enabled.
Use the hardware based floating-point square function on the G5. (Use with -mcpu=970, -mtune=970, and -mpowerpc64.
Partial redundancy elimination on trees.
Full redundancy elimination on trees.
Sparse conditional constant propagation on trees.
Loop header copying on trees. Enabled by default with -O, but not with -Os.
-ftree-dce -ftree-dominator-opts
Dead code elimination on trees.
Elimination of checks based on scalar.
Loop optimization on trees.
Linear loop transformations on trees to improve cache performance and allow additional loop optimizations.
Loop invariant motion on trees.
Scalar replacements of aggregates.
Copy renaming on trees.
Temporary expression replacement during SSA to normal phase.
Live range splitting during SSA to normal phase.
Loop vectorization on trees. This enables -fstrict-aliasing, by default.
Apply the strictest aliasing rules.
Allow blocks and functions of assembly code in C or C+ source code.
Automatic creation CoreFoundation-type constant. (See the gcc manpage for details.)
Allow the use of Pascal-style strings.
Weakly coalesced definitions are ignored by the linker in favor of one ordinary definition.
Use the vtable to call virtual functions, rather than making direct calls.
Make kernel extensions loadable by Darwin kernels. Use in combination with -fno-exceptions and -static.
Coalesce instantiated templates.
Support structured exception handling in Objective-C. (See the gcc manpage for more details.)
Instructs dyld to load the object file at runtime.
Issue a warning about _TAG_ use only once if necessary.
Issue a warning if preprocessor directives end with extra tokens.
Issue a warning if a file ends without a newline character.
Don't issue a warning about the keyword "long' used in an AltiVec data type declaration.
Same effect as -Wall -Wno-parentheses.
Don't issue a warning if the long-double type is used.
Optimize for PPC7450 and G5. The -fast flag optimizes for G5, by default. This flag can be used to optimize for PPC7450 by adding the flag -mcpu=7450. To build shared libraries with -fast, include the -fPIC flag.
Inhibits linking with shared libraries provided that all of your libraries have also been compiled with -static.
Not supported on Mac OS X.
Used to build Mach-O dylibs (see Chapter 12).
Compiled code will itself not be relocatable, but will have external references that are relocatable.
Calls that use a 32-bit destination address are compiled.
All members of static archive libraries will be loaded. (See the ld manpage for more information.)
Files that have the wrong architecture will result in fatal errors.
Bind all undefined references when the file is loaded.
Results in Mach-o bundle format. (See the ld manpage for more information.)
-bundle_loader executable
The executable that will load the output file being linked. (See the ld manpage for more information.)
Allow cast and conditionals to be used as lvalues. Although this is on by default in Apple's GCC 4.0, a deprecation warning will be issued whenever an lvalue cast or lvalue conditional is encountered as such lvalues will not be allowed in future versions of Apple's GCC.
Disallow lvalue cast and lvalue conditionals.
Enable software floating-point emulation rather than using the floating-point register set. This emulation is not performed on Mac OS X since the required libraries are not included. On Mac OS X this flag prevents floating-point registers from copying data from one memory location to another.
Optimize for size. On Apple PowerPC, this disables string instructions. To enable string instructions, use -mstring.

Wild Dog Had An Ultimate Face-off With the Tiger, Leaves Internet Surprised
The one great positive aspect of the global lockdown post the Covid19 pandemic has been the revival of mother nature. Flora and fauna have been flourishing due to the drastically decreased man-made pollutants all around.
Footages of numerous wild animals walking on the streets of cities and towns have been posted on various social media circles almost every day. Many endangered and even though to be extinct animals have been seen coming out from the dense forest interiors.
The Nilgiris of Southern part of India is home to numerous wild animals that are protected under the various National Parks like Kabini, Nagarhole, Madhumalaietc. From Tigers to Wild Black Bears, Fox, Bison, Jaguar, Leopards, etc, there are many such animals that freely roam around in these National Parks.
One of the anti-poaching surveillance cameras in Kabini caught a very strange yet heart touching instance. The recording showed a wild dog sending out a frantic warning of tiger approaching residential territory in South India to alert the public.
Dhole, a breed of India wild dogs are known for their exclusive and very unique vocal calls for communication. Though they are wild dogs, they have been known to be very friendly towards humans, unlike dingos.
The footage shows the tiger approaching the wild dog along the border of the Kabini forest. However, instead of running away, the Dhole surprisingly holds himself in an alert position and begins to give out repeated warning calls.
The strangest fact is that Tiger is a stronger and more vicious predator, but instead of attacking, it turned around and runs away as soon as the Dhole begins to give out a warning call. Indian Forest Service official Susanta Nandy who posted the video said, this was one of the most strange behavior he had ever seen from a tiger.
Many people have been admiring the dog for saving the lives of numerous people who stay in close vicinity of the area where the incident actually occurred. The tweet has garnered over 30,000 views and retweeted over a thousand times already.
