Automatic Photoelectric Device for Most Optimum Illumination of Objects

In paper the automatic photoelectric device (APD) for most optimum illumination of streets and objects is described. The offered photovoltaic system is mean for automatic switching on and switching off to an electric circuit of electric systems and illuminating lamps. This system differs from existing ones that the silicon solar cell is used for the purpose increase of input sensitivity and an output power, and so the circuit of our system is simpler. One of main technical advantages is that the relay for a current of 10A is used on an output of the automatic control system. This advantage allows linking up not only as it is usually, one lighting lamp, but also electric installation by power up to 2kW at 220V (for 1 APD). For automatic control of several of the photoelectric devices for optimum illumination of several objects the automatic control system (ACS) and software support are created. As have shown experiments, for one of areas of Baku use of only APD has allowed saving up to 16 % of the electric power. Use of ACS has resulted in addition up to 6 % of economy of the electric power

Matrix Composite Sensor For Measurement Mere Stream

For detection and research obvious and latent heat stream in mere has been developed the extended high-resistance sensor made on special matrix technology. Detector measures both temperature of surrounding sea water, and direction of a stream. Signals from the sensor, amplified of the operational amplifier, by dint of the interface input into a computer for the further processing results of measurement and archiving of the data. The software package of processing and archiving of results of measurement is created

A solar power plant with a high performance solar cells and thin concentrators made of aluminumbacked epoxy coated polymers

The offered module of the solar cell includes light collected system on the basis of a cylindrical thin concentrator and the bar of silicon photocells with a radiator for air cooling. The concentrator is a light collecting system and is manufactured from epoxy with a depth of 5 mm coated from the inside by a polymeric film of depth 70 μm and of aluminium by depth 3 μm. Small depths of materials of the concentrator cause its low cost compared with the concentrators produced from glasses. The estimated cost of a concentrator with an area of 1 m2 is 10

Thermophotovoltaic Properties of Bi2Te3 AND Bi2Se3

Thermophotovoltaic properties monocrystals Bi2Te3 p-type and Bi2Se3 are investigated. P-n film structures of p-Bi2Te3–n-Bi2Se3, received by a method of discrete thermal evaporation in a uniform work cycle, are suitable for usage in thermophotovoltaic devices. It is demonstrated, that the wide spectrum of sensitivity and stability to the concentrated solar radiation of thermophotovoltaic elements on the basis of AVBVI are advantage in comparison with traditional solar cells. The modelling of concentrator solar cells with thermophotovoltaic converters is carried out in order to guide the technology to increase the performance of these devices

Investigation Of Photo-Generation Processes In Semiconductive Polymers

In article the perspective of researches semi-conductor polymers for creation of photo-electric converters is considered. The processes of photo-generation of charge carriers in a molecular solid state are investigated. The role of the weak intermolecular interaction causing process of photo-generation of charge carriers through a status of the coulomb connected pair is shown. The first results of semi-conductor polymers-silicon systems investigations were reported. Such as of polymer composite materials we have used oligohydroguinone, oligo-αnaphthol, oligo-β-naphthol, oligo-amino-phenylen. Current-voltage characteristics of these polymer-silicon heterojunctions were investigated. The structural regularities of change of the photoeffect quantum efficiency in semiconductive polymers and their molecular complexes are investigated

On features of potential distribution in avalanche photodiodes with deeply buried pixels

The shape of potential distribution in micro-pixel avalanche photodiodes (MAPD) with deeply buried pixels is investigated. It was found that the electrons created in the photosensitive part of the device are collected to the corresponding n-pixel and multiplied in the avalanche region. At the same time the holes generated in the semiconductor substrate passes through the gaps between the n-pixels and therefore they are not amplified. This results in improvement the both signal/noise ratio and radiation resistance of the devic

Palivizumab: Four seasons in Russia

In 2010, the Russian Federation (RF) registered palivizumab - innovative drug, based on monoclonal antibodies for passive immunization of seasonal respiratory syncytial virus (RSV) infection in children of disease severe progress risk group, which include primarily premature infants, children with bronchopulmonary dysplasia and hemodynamically significant congenital heart disease. Currently, palivizumab is included in the list of recommended medicines and medical care standards of different countries, including Russia. In the review the results of Russian research on the progress of RSV infection, its epidemiology and immunization experience gained over the 2010-2014 period are summarized in relation to the foreign data. During the four epidemic seasons palivizumab immunization covered more than 3,200 children of severe RSV infection risk group with a progressive annual increase in the number of patients who received the drug. Geography of palivizumab immunization is also greatly expanded in our country during this time. If during the first two seasons measures of immunization were taken mainly in Moscow and St. Petersburg, at the present time, thirty one territorial entities of the Russian Federation have the experience in the drug application. Analysis of the results of RSV infection immunization (made in several regions) confirms the high clinical efficacy and palivizumab safety already demonstrated in international studies. In addition, the analysis presents the potential to improve the efficiency of the integrated RSV infection immunization programs, realizing in the establishment of high-risk child group register, adequate counseling for parents, as well as the development of the routing of patients and coordination of interaction between different health institutions during the immunization. © 2014, Izdatel'stvo Meditsina.
