The experimental temperature dependences of the basic MOSFET parameters (the transconductance parameter and threshold voltage) in a wide temperature range covering both cryogenic temperature and regular temperatures are considered. The methods which acceptable for engineering practice and allow to approximate the experimental temperature dependences of the basic MOSFET parameters by the simple analytical expressions in the form of linear or power functions are presented. The investigated MOSFETs was designed for work as active elements of amplifying devices. Temperature dependences of the basic MOSFET parameters are needed for estimation of the sensitivity, prediction of uptime and optimizing the choice of refrigerant for low-noise amplifiers.

The method of laser therapy is based on synchronization of phases of inflow (anacrotism) and outflow of blood (catacrotism) in the field of the pathological center with phases of a being narrowed and extending laser spot on a projection of this pathological center. It is supposed that being narrowed on a projection of the pathological center the spot of laser light stimulates blood inflow to the spot center, and the extending spot of a laser beam – activates blood outflow in the direction from the spot center to its periphery. The developed technique of the automated correction of hemodynamic frustration consists in pilot signal formation (in charge of the power and laser positioning) for the laser machine on the basis of a difference between a reference rheogram and a rheogram of the patient (a body site) in real time.The offered technique has to allow to use more efficiently methods of laser therapy at treatment of violations of a blood-groove. The technique is calculated on the basis of numerical experiment by means of methods of mathematical model operation.In the real experiment the question of synchronization of the reference and measured signal is considered solved though this task represents a subject of separate researches.The received pilot signal can be in real time transformed to the current signal operating positioning and laser power.The method gives the chance of an operating control of a condition of the patient and blood-groove diagnostics to, in time and after a session of laser therapy. Development provides possibility of adaptive individual correction and optimization of parameters of influence during a session and a course of treatment.

The article highlights the conditions for effective diversification. The factors of the internal environment, affecting the efficiency of diversification. 
The methods of analysis of the market, allowing you to tailor a strategy of diversification to the changing conditions of competition in the market. 
Shows the need for structuring diversification, given the group on current issues, as well as a comprehensive solution to these problems, we have an in-depth analysis and diagnosis with the subsequent implementation on the basis of this analysis in the operation of the enterprise. 
There are four stages of diversification of copyright: in the first step to solve the problem of selecting priority areas for development within the economic entity, the second stage is the process of structuring a problem specific to the business entity; the third stage should be determined by the direction of the use of innovative resources as the main form for priority directions ongoing diversification; fourth phase to establish mechanisms for the implementation of diversification at the business entity.

This article considers the causes of halitosis and methods of the diagnosis. Halitosis, syndrome of bad breath caused by pathological condition of the oral cavity or internal organs and systems, has a significant impact on the patient's social life. Analysis of the composition of exhaled air may become a promising way to diagnose halitosis, as the direct relationship between the compositions of molecules of oxygen, carbon dioxide, nitrogen oxides, ammonia etc. and the causes of halitosis were found. The article's authors review and analysis the methods of measurement of qualitative and quantitative composition of exhaled air. The most common methods include the use of electrochemical, optical sensors, infrared spectrometers and mass spectrometers. The latter method is positioned as the most optimal method of analysis of exhaled air due to its high accuracy, selectivity and sensitivity. The authors' portable mass spectrometer being developed is represented. At this stage it can detect traces of oxygen and carbon dioxide, which inject into the device through the capillary system or membrane one, in gas samples in real-time mode.
