This paper describes digital radio astronomical receivers used for decameter and meter wavelength observations. Since 1998, performing on-the-fly dynamic spectrum calculations or waveform data recording without loss have been at the UTR-2 telescope, URAN VLBI system, GURT new generation telescope. Here, we detail these developed operation in strong interference environment that prevails range. Data collected with allowed us to discover numerous objects phenomena low frequencies, a summary of...
Abstract. The airborne spectral observations of the upward and downward irradiances are revisited to investigate dependence near-ground albedo as a function wavelength in entire solar spectrum for different surfaces (sand, water, snow) under conditions (clear or cloudy sky). radiative fluxes were determined by diffraction spectrometer flown on research aircraft that was performing multiple flight paths near ground. results obtained show does not generally increase with increasing wavelengths...
A molecular analysis of HIV-1 subtypes and recombinants circulating in cities the Russian Far East was performed. The study included samples from 201 outpatients Vladivostok, Khabarovsk, Blagoveshchensk. In most parts Russia, patients are infected with subtype A, known as IDU-A variant. Subtype B, including IDU-B variant, is rare Russia but widespread Ukraine, CRF02_AG prevalent Central Asian countries Siberia, Russia. One challenges this to determine whether landscape HIV infection region...
A joint Mexican, Russian, and American research effort has been initiated to develop new methods remotely sense atmospheric parameters using ground‐based, aircraft, satellite observations. As a first step in this program, ground‐based spectrophotometric measurements of the direct solar radiation have obtained for extremely polluted Mexico City atmosphere period April–June 1992. These observations were made at mote than 1300 channels spectral range 0.35–0.95 μm. In ultraviolet (UV) portions...
To analyze HIV-1 genetic variants in Kazakhstan, sequences were obtained from 205 antiretroviral-treated (ART) and naive patients 2009-2013. Samples collected the most populous cities provinces of Kazakhstan. On basis phylogenetic analyses partial pol sequences, subtype A variant intravenous drug user (IDU)-A (which is dominant former Soviet Union) was found 60.0% individuals, followed by CRF02_AG (34.6%); rest samples B, CRF03_AB, CRF63_02A1, CRF07_BC. The proportion has increased...
There is scarce information about the molecular epidemiology of HIV-infection in Armenia (former USSR). The objective this work was to estimate distribution HIV-1 subtypes country and get any HIV drug resistance naÏve patients.A joint study involving 78 patients carried out Yerevan, Moscow, Russia 2009-2013. cohort studies included mostly IDUs (28.2%) heterosexuals (69.2%).The phylogenetic analyses based on population sequencing partial pol gene found subtype A1 being most prevalent (92.3%),...
Objectives During the last two decades, HIV‐1 has been spreading rapidly in former Soviet Union republics including Kyrgyzstan. The current molecular monitoring of HIV‐infection epidemic is carried out Russia only with no or limited data from other FSU countries. aim this work was to investigate prevalence genetic variants circulating Methods Blood collection HIV‐infected patients by local specialists informed consent and questionnaire answered each patients. total number samples 100. washed...
Global climate change observed during the last two decades of 20th century has attracted attention world's scientific community. The non-uniqueness atmospheric aerosols and impact clouds on warming (or cooling) atmosphere-underlying surface system need more detailed modelling to elucidate optical properties atmosphere surface. In multi-angle remote sensing, inverse problem retrieval using radiances over only one pixel presents a fundamental difficulty involving multiplicity solutions....

Background Enfuvirtide (ENF/Fuzeon/T‐20) was the first member of class ‘fusion inhibitors’. This approved for treatment HIV infection in year 2003 Europe and USA. Fuzeon has not yet Russia but near future his introduction expected. Resistance to ENF been associated with mutations HR1 domain at codons 36–45. Mutations outside this region HR2 may also serve as secondary mutations. Unique highly homogeneous HIV‐1 subtype A variant‐IDU‐A is most prevailing CIS countries. genetic variants...
The lidar sounding in the cloudy atmosphere needs accounting multiple scattering. standard approach for retrieval of optical parameters and morphology aerosol particles might be not sufficient. Here theoretical analyti cal numerical methods calculation scattering contributions backscattered signal are used. thickness clouds that provokes a distinct multiply scattered light is determined. possible correction as subtraction part from registered proposed optically thicker than 4. routine...
Airborne spectral radiative data are used for estimation of bluing radiation within clouds. The kind vector with three components (irradiance or radiance at UV, visible and near IR channels) is considered its transformation cloud analyzed. A similar procedure has the case clear atmosphere. Russian observation upward downward fluxes NASA Cloud Absorption Radiometer (CAR) diffused intensity in 8 channels taken consideration cloudy Spectral dependence scattering coefficient clouds was revealed...
The results of lidar sounding in the Resource Center "Observatory Environmental Safety" St. Petersburg University, Research Park, have been obtained center Petersburg. Observations are accomplished during 12 hours on 5 March 2015, from 11 am till pm. Four time periods considered. Results AERONET observations and retrieval at 4 stations around region considered addition.
