The radio on the hunt

I'll start with the most important, with what values, it seems to me, any good hunter. There is in the nature of portable radios (radio in some circles to call walkie abbreviated), working in the forest at a distance of 5-15 kilometers. No responsible specialist never promised specific figures, because anticipate all the nuances of the terrain, time of year, weather conditions, humidity, point of a hill, solar activity, the angle of the radio with the conventional (regular) whip antenna during its use et al., Affecting the quality and range radioobscheniya another hunter (same Read more [...]

Building an effective bait

In this recently begun century it is already a high degree of confidence that the soft silicone foam and spinning lures virtually all fishing conditions ousted earlier habitual «iron». Only lures with their huge variety once can compete in this business. But in the case of wobblers fishing success is often directly related to the presence of the angler a wide range of very expensive cost of lures.We must say at once that in the case of silicone and foam is quite possible to do a minimum number of cheap components and achieve a very good result, if you learn with the Read more [...]

Scientists have analyzed the noise before the eruption of the volcano

July 15, 2013. Redoubt Volcano in Alaska before the eruption has issued an unusually high-pitched sound that arose due to fluctuations in the Earth's crust in a series of small earthquakes preceding the eruption, according to an article published in the journal Nature Geoscience. Volcanic eruption is often preceded by the slack of the earthquake. They can go after each other with such a small gap that the crust, fluctuating, low-frequency issues «trill». Scientists led by a graduate of the Moscow State University of Geodesy and Cartography Ksenia Dmitrieva at the University of Stanford Read more [...]

How to check the pulse. What to do?

Pulse — this periodic jerky expansion of the walls of arteries. Best of all, he felt in two places — on the wrist, and in the deepening of the neck to the right or to the left of the chin. 1. The pulse at the wrist is located below the base of the thumb in the hollow between the two bones. 2. Feel for his three fingers and gently push. 3. Do not press the pulse with your thumb, as it is your own heartbeat, and you can take your own pulse for the pulse of another person. 4. The pulse in the neck (throat) is located in the hollow lower jaw bone to the side of the Adam's Read more [...]

Electromagnetic karma

Nature must be designed in the likeness. Therefore, for the description of, say, the physical level can use the analogy of water. All space must be filled with some medium through which transmitted vibration. Therefore, for the description of, say, the physical level can use the hydraulic model. Only difference in the frequency of vibration. If we look at the float in the water, when the fish are biting, there is a vibration, and float on the surface and swinging from it in different directions diverge around waves. Fig.1. Waves on a water surface. If we stick to the analogy, on the psychic Read more [...]

Scientists say that the number of earthquakes in the world has increased

Data last month (December 2012) around the world for earthquakes indicate the size and growth of a significant increase in the frequency (magnitude 5.5 +) earthquakes, according to a review publication Guardianlv. The data show an alarming tendency to increase the strength and frequency of earthquakes in the world. These results are in agreement with the statistics of the site USGS (U.S. Geological Survey), which shows an increase in the frequency of large earthquakes (M 5.0 +). These trends also show that the depth of the earthquake decreased, they come closer to the surface of the Earth. Read more [...]

Gravity. The unification of interactions

One of the problems of physics is to establish connections between disparate phenomena in the union of the various forces of nature, the search for a single cause to explain the physical phenomena of a different nature. Currently, we know four types of fundamental interactions: gravitational, electromagnetic, weak and strong, which determine the existence of our universe. Combining the laws of physics is to bring unique equations describing all types of interactions. This task involves three main elements: a description of the combined interactions with one or more of the constants included Read more [...]

Frequency of the noise

Frequency of the noise is due to standing waves are formed in the propagation of electromagnetic waves around the Earth. It is believed that the excitation is due to lightning.Frequency of the noise is calculated very simply. Take the speed of light 300,000 km / c and is divided by the circumference of the Earth 40,000 km and 7.5 Hz is obtained for the first harmonic. Given that the wave travels between the Earth and the ionosphere radius increases and turns, just 7.8 Hz (first harmonic), as shown by instruments.I am embarrassed that the cause of excitation considered lightning, though perhaps Read more [...]

Scientists: Tropical cyclones have become more

The South-Eastern United States has experienced a growing number of large storm surges from tropical storms since 1923. on 15 October. Tropical cyclones in the present was more than in the past, or it seems to us due to the fact that now we often hear about them, as the media began to pay more attention to this, and now that the cyclones are easier to detect using satellites? Held at the Niels Bohr Institute studies clearly show that there is a growing tendency of the formation of cyclones, if the climate becomes warmer than it was in the previous few years. The results of this study published Read more [...]

Noise and its effects on humans. Sound effect

Man perceives sound through hearing, the skull, and especially when the sound intensity - all over. For a long time, the effect of noise on the human body was the object of a special study, though its dangers were known for a long time and the rules limiting noise in cities and public life existed in ancient times. For example, in China more than 2,000 years ago, a law was passed, which read: "He who blasphemes God, should not be hanged, but the flute players, drummers and shouters have to continually play in front of him until he falls down dead, as it is the most painful death, you can Read more [...]

Sources of electromagnetic fields and Safety

Sources of electromagnetic fields are divided into two groups: • sources that generate low and extremely low frequency (0 Hz to 3 kHz); • sources that generate radiation radio frequency (3 kHz to 300 GHz). Low and extremely low frequency generate all of the generation, transmission and distribution of electricity (power lines, substations, power plants, and various cable systems) and transport of electric traction. Length of transmission lines (PTL) and 6-1150 kV voltage in Russia is more than 4.5 million kilometers, and the length of transmission line class 35-1150 kW, representing a potential Read more [...]

Anatomy of thunder

For obvious and simple statement, "Thunder appears as a consequence of electrical discharge of enormous power, as a result of lightning" is a lot of very interesting details. And the details are not obvious, for clarification painstaking research and a lot of time. Suffice it to say that even the prosperous beginning of this century physics could not clearly answer a seemingly simple question: What are the specific mechanism for generating sound waves from lightning, heavy duty speaker is designed as a thunderstorm? While discussed four possible mechanisms, so to speak, gromoobrazovaniya, Read more [...]

Scientists: Tropical cyclones become more

In recent years, more and more clearly the tendency to increase the number of tropical cyclones than it happened a couple of decades ago. And perhaps it is not so, and we think that because increasingly the topic being discussed in the media, and hurricanes can now be anticipated with a satellite? Based on the results of studies that have been conducted in the Niels Bohr Institute, it was found that the recent cyclones do occur more often, causing what is called global warming. Information with the results of the study presented in the journal PNAS (Proceedings of the National Academy of Read more [...]

The frequency spectrum of the noise

The intensity of industrial noise, which includes a wide range of sounds, is a total concept. Level noise intensity or the total sound pressure level in decibels measured by a special device. Since the harmful effects of noise, according to a widespread opinion, depends not only on the general level of intensity, but the intensity of its constituent frequencies, especially high, measure, in addition to the total intensity, the intensity of the individual octave band or 1/3 octave. Spectral analysis is performed in different ways. One of them is an audio recording on tape, and then the camera Read more [...]
