Estimators of a nuclear explosion

There are several formulas measuring radiation from a nuclear explosion, which can help determine the scope and extent of radioactive contamination. 1.Opredelenie epicenter distance is up to you on time transmission of sound:S (km) = T (sec) / 3 T.e.uvideli atomic explosion, detected how many seconds you hear the sound and divided into 3 - got the hypocenter distance in kilometers to you. 2.Opredelenie power of a nuclear explosion on the lifetime of the emission of the fireball:Q (kt) = T (s) * 3 (degree). T.e.registriruem glow time and erect a nuclear explosion in the third degree, and find power Read more [...]

Periodization: You've seen the condition in magazines. A distinctive program involves block out a month roughly for soft survival education (the institution or pedestal stop), followed by a few weeks adapting to more integrated oeuvre (the figure flow), so a few weeks of high-intensity grooming (the operation menstruum), followed by retrieval.Funfair sufficiency, but that's a periodization project for multitude who center but one variation and maybe scarce one eyeshade a class. Perhaps you dog-tired the retiring two months nordic skiing. Mayhap you've been to spinning form doubly a workweek and Read more [...]

Impulse noise

For recent literature devotes considerable attention to the issue of switching noise. The very concept of impulse noise is not always sufficiently defined and the duration of the pulse repetition frequency, parameters, and, finally, the general background noise in which it is generated is often not given. Perhaps this explains the contradictions in assessing its effect on the organ of hearing in comparison with the effect of a stable industrial noise on the same parameters. According Dierofl (1962) impulse noise a harmful effect on the organ of hearing than equal to him in a constant intensity Read more [...]

The perception of distance-2

These difficulties have led many researchers, including the author of this book, to the denial of discrimination techniques, which are based on the detection of simple and easily observable reactions baby. A good example of the simplicity and usefulness of these techniques can serve as the study of perception of distance, conducted by McKenzie and Deem (1972). As a measure of discernment, they used the duration of fixation. When the baby again and again impose the same stimulus, and then stimulus varies, the amount of time during which the child looks at the stimulus increases, if baby can distinguish Read more [...]

Influence of dose and duration of smoking on the incidence of lung cancer

The risk of developing lung cancer is immeasurably more dependent on duration of smoking than from an increase in the number of cigarettes smoked daily, for example, a threefold increase in this number can cause approximately a three-fold increase in the risk of developing the disease, while a similar increase of the duration of smoking can to 100-fold increase in risk. In this regard, a few decades after smoking cigarettes is becoming widespread, the rate of increase the incidence of lung cancer in a national scale may be deceptively low, even if in the final analysis, these figures will be extremely Read more [...]

Pulse current

Pulse current - is the electric current, recurrent brief portions (pulses). In medicine increasingly use surge current, consisting of rhythmically repetitive current pulses of constant direction and different forms - rectangular, trapezoidal, triangular, exponential (currents Lapicque) or sinusoidal current pulses. The main characteristics of the pulse current are: the amplitude a, t the duration and period T, or the repetition rate and pulse shape.
