High speed rail Britain’s first link hasn’t worked as planned say critics

Introduction[ edit ] The speed of gravitational waves in the general theory of relativity is equal to the speed of light in a vacuum, c. Formally, c is a conversion factor for changing the unit of time to the unit of space. Thus, the speed of “light” is also the speed of gravitational waves and any massless particle. Such particles include the gluon carrier of the strong force , the photons that make up light hence carrier of electromagnetic force , and the hypothetical gravitons which make up the associated field particles of gravity however a theory of the graviton requires a theory of quantum gravity. Static fields[ edit ] The speed of physical changes in a gravitational or electromagnetic field should not be confused with “changes” in the behavior of static fields that are due to pure observer-effects. These changes in direction of a static field, because of relativistic considerations, are the same for an observer when a distant charge is moving, as when an observer instead decides to move with respect to a distant charge. Thus, constant motion of an observer with regard to a static charge and its extended static field either a gravitational or electric field does not change the field. For static fields, such as the electrostatic field connected with electric charge, or the gravitational field connected to a massive object, the field extends to infinity, and does not propagate.

Sensorimotor feedback[ edit ] Response to stimuli[ edit ] The process of becoming aware of a sensory stimuli and using that information to influence an action occurs in stages, and reaction time of simple tasks can be used to reveal information about these stages. Reaction time refers to the period of time between when the stimulus is presented, and the end of the response. Movement time is the time it takes to complete the movement.

Some of the first reaction time experiments were carried out by Franciscus Donders , who used the difference in response times to a simple reaction task and a choice reaction task to determine the length of time needed to process the stimuli and choose the correct response. Further research has provided evidence that these stages do exist, but that the response selection period of any reaction time increases as the number of available choices grows, a relationship known as Hick’s law.

There is a reference that specifies the desired value for the system, and the output of the system is fed back and compared to the reference for error detection and, if necessary corrected

In terms of “Year of the Earth,” it begins on January 1 and ends about 26 February. The process of solidification is poorly known, however, and the Hadean may have lasted as long as one billion years. This is the period during which the Earth’s crust [1] was formed. This crust melted and reformed numerous times, because it was continuously broken up by gigantic magma currents that erupted from the depths of the planet, tore the thin crust, and then cooled off on the surface before sinking again into the heart of the Earth.

The details of this slow, destructive process are still uncertain. However, it is thought that the heavy elements, like iron, tended to sink towards the center of the Earth because of their higher density, while the lighter components, particularly the silicates, formed an incandescent ocean of melted rock on the surface. Approximately million years after the birth of the Earth, this incandescent landscape began to cool off.

Share5 Shares 12K It is well known that China has an ancient and glorious history, from the feudal periods ending in BC through the three Imperial and Intermediate Eras, up to the Modern era — over years of dynastic reigns. It may also be well known that China is the source of many wonderful and useful inventions from spaghetti to gunpowder. This list, however, will take a slightly different slant of the topic: Chinese inventions and developments that were not known to or adopted by the Western European world for many decades and sometimes centuries after they were common place in China.

Some you may be familiar with, others perhaps less so. William Harvey is credited with discovering the circulation of blood in It was described in Chinese documents in the 2nd Century BC. This technique allows the crops to grow faster and stronger. It facilitates more efficient planting, watering, weeding and harvesting. There is also documentation that they realized that as the wind travels over rows of plants there is less damage.

Choose the proper gold pan for you Use a gold pan that is a good size for you. I think the newer plastic pans are superior to the old metal pans. They also come in various colors which helps you spot the gold in the bottom of your pan. You can also get a good quality gold panning kit that also include classifiers, snuffer bottle, and other handy tools for gold recovery.

Use snuffer bottle and magnet You will probably find lots of black sands when you are panning and sluicing for gold. Some of these black sands are magnetic, and you can remove them with a strong magnet. There are specialized magnets for this task that work quite well and are reasonably priced. These are a handy tool for removing black sands from your gold pan. Every prospector should have a snuffer bottle. They only cost a couple bucks and they work great.

Be aware that sometimes collecting black sands with a magnet will also pick up a bit of gold. Not all black sands are magnetic through, and you will have some fine black sands, garnets, and other material mixed in with your fine gold. Use a snuffer bottle to expose the fine gold underneath these other materials. It is a simple, inexpensive tool that every prospector should keep in their clean-up kit.

The first measured 24 hour production from Bakken wells is a very good predictor of the future production of that well. And it has also been confirmed that new wells with higher well numbers are producing a lot less. By searching these two lists, then eliminating the duplicates that appear on both lists, we find that perhaps 70 to 80 percent of all wells report their first 24 hours of measured production. An example below, and notice the second well listed does not give any production numbers: I have collected, from this source, the data from 2, wells dating from November 1st to the present date.

Enno Peters gathered data from several thousand Bakken wells dating from the early Bakken t mid There were a more matches than this but had no data or incomplete data. But it was mostly because only a little over half my data overlapped his. I converted his monthly data to barrels per data by dividing the monthly data by There were sometimes great anomalies in the data so to smooth things out, on the first three charts below, I used a 50 well average. Here are the results.

The horizontal and right axis is first 24 hour barrels. When I sorted the data by production in the first 24 hours I found a strong correlation with the second months production. This was especially true with first 24 hour production up to 1, barrels.

Friday, November 23, October 24, Since , there have been eruptions and 52 episodes of notable volcanic unrest at 44 U. When erupting, all volcanoes pose a degree of risk to people and infrastructure. However, the risks are not equivalent from one volcano to another because of differences in eruptive style and geographic location. The assessment uses 24 factors to obtain a score and threat ranking. The findings are in the newly published Update to the U.

Eleven of the eighteen very high threat volcanoes are in Washington, Oregon, or California, where explosive and often snow- and ice-covered volcanoes can project ash or lahar debris flow hazards long distances to densely populated and highly developed areas. These include Mount St. The threat ranking is not a list of which volcano will erupt next. Rather, it indicates how severe the impacts might be from future eruptions at any given volcano. The volcanic threat assessment helps prioritize U.

It is a way to help focus attention and resources where they can be most effective, guiding the decision-making process on where to build or strengthen volcano monitoring networks and where more work is needed on emergency preparedness and response.
