Role of spatial coherence in polarization tomography
We analyze an experimental setup in which a quasi-monochromatic spatially
coherent beam of light is used to probe a paraxial optical scatterer. We
discuss the effect of the spatial coherence of the probe beam on the Mueller
matrix representing the scatterer. We show that according to the degree of
spatial coherence of the beam, the \emph{same} scattering system can be
represented by \emph{different} Mueller matrices. This result should serve as a
warning for experimentalists.Comment: 3 pages, 1 figur

Research of Influence Modification of Natural Concentrate on Quality Metal
Questions of increase of mechanical, technological and service properties of metal at minimum cost to produce it are relevant for the metallurgical enterprises. Modification of complex steel alloys containing reactive elements is one of the effective ways to improve the quality of steel. At the same time the direct costs for the use of modifiers are 0.2-0.3%, which little effect on the cost of production. The paper presents the results of the application of natural concentrates as a modifier steel. The effects on the metal quality changes due to the impact of the modification concentrates demonstrate the effectiveness of their application. As a result of modification decreased the content of nonmetallic inclusions and grain size. Reduction of impurity modified metal of was the cause more high plastic properties, especially, impact strength at ordinary and low temperatures of tests. Based on the experimental data evaluated hardening mechanisms that lead to a significant improvement of physic-mechanical properties of the metal workpiece after administration modifier
Development of Nuclear Microsatellites for the Arcto-Tertiary Tree Zelkova carpinifolia (Ulmaceae) Using 454 Pyrosequencing
Premise of the study: The current study aimed at developing nuclear
microsatellite markers for the relict tree species Zelkova carpinifolia, which
is threatened in its natural range in the South Caucasus. Methods and Results:
Pyrosequencing of an enriched microsatellite library on the Roche FLX platform
using the 454 Titanium kit produced 86,058 sequence reads, most of which
contained short tandem repeats. Eighty microsatellite loci identified using
the software package QDD version 1 were selected and tested for proper PCR
amplification. Of these, 13 allowed proper amplification and were shown to be
polymorphic among a sample of 25 Z. carpinifolia specimens from various
geographic origins. Conclusions: The set of microsatellite markers will be
suitable for the assessment of genetic diversity in Z. carpinifolia. They will
allow for an examination of phylogeographic patterns as well as of population
structure and gene flow within this species
Complex radiation-thermal history of Kaidun meteorite on data of track study of silicate minerals
The results of track study of approximately 80 individual silicate mineral crystals (ol, px, plag) picked out from Kaidun meteorite are presented. A wide range of observed rho(sub VH) value distributions indicate the complex irradiation history of Kaidun minerals. In one anortite crystal having two track groups with different parameters the pre-accretion irradiation traces were observed in all probability

Objectives. To determine the physical and chemical properties (bulk density, ash content, total pore volume, abrasion, humidity, sorption capacity) of sorbent based on ash-and-slag waste from heat power engineering, calcined and modified with a Tiprom K organosilicon water repellent.Methods. The physicochemical properties of the modified sorbent were determined using an experimental method according to the methods of regulatory documents on equipment verified and certified in the prescribed manner.Results. Ash and slag taken from the ash dump of the Novocherkasskaya GRES power station were dried, then calcined at a temperature of 600 Β°C for 30 min and modified with a Silor hydrophobizing silicon-containing liquid (HSL). The modifier/ash ratios (by weight) were 1:20, 1:10, 1:5, 1:3, and 1:2. The optimal ratio was 1:5 at a sorption capacity with respect to hexane of 0.86 g/g. The modification temperature was optimized in the temperature range of 110β200 Β°C. The optimal approach it to dry samples at 160 Β°C to constant weight. At a temperature of 200 Β°C, sintering of the material was observed. The analysis of HSL modifiers was carried out in terms of the price/sorption properties ratio. The following were considered as HSL: Silor, HSL-11BSP, HSL 136-157M, PROFILUX, Tiprom K, Tiprom U. The optimal modifier Tiprom K was selected. The physicochemical properties of the modified sorbent obtained at a ratio of 1:5 (by weight) and dried at 160 Β°C were experimentally determined. The sorption properties were studied on the water surface with respect to various oil products: fuel oil, kerosene, AI-92 gasoline, nefras, oil sludge, and n-hexane. The smallest sorption capacity was obtained with respect to n-hexane, amounting to 0.86 g/g. During the experiment, it was found that half of the sorption capacity was filled with oil in the first minutes of contact. Complete sorption time was 30β40 min for relatively light hydrocarbons (n-hexane, AI-92 gasoline, kerosene, nefras), 40β60 min for oil sludge, and more than 60 min for fuel oil. Experiments established that the sorption process does not depend on the matrix (salinity) of water. A visual assessment of the color intensity of the residual spot of oil sludge allowed a conclusion to be made about a significant content of oil products in the case of sorption of oil sludge by quartz sand based on the residual yellow layer of oil sludge. In the case of sorption of oil sludge by calcined and modified sorbents, the residual oil products were insignificant. A comparative analysis of data on the effectiveness of the developed sorbent and currently available analogues based on sludge and slag is presented.Conclusions. The next physicochemical properties of the sorbent modified with HSL Tiprom K were determined: bulk density was 0.621 g/mL, ash content was 97.1%, total pore volume by water was less than 0.05 mL/g, attrition was 8.8%, humidity was less than 0.5%; sorption capacity, in g/g: for n-hexane, 0.86; for AI-92 gasoline, 0.89; for nefras, 0.93; for kerosene, 0.99; for oil sludge, 1.18; for fuel oil, 1.46. The efficiency of cleaning a solid surface from oil sludge with a calcined sorbent was 97%, and with a modified sorbent 95%. The modified sorbent has high buoyancy when saturated with oil products and the ability to retain them for a long time.Π¦Π΅Π»ΠΈ. ΠΠΏΡΠ΅Π΄Π΅Π»Π΅Π½ΠΈΠ΅ ΡΠΈΠ·ΠΈΠΊΠΎ-Ρ

Fluorescence Analysis of E. coli Bacteria in Water
The fluorescence analysis of Escherichia coli (E. coli) bacteria was done. It has been established that a luminescent signal from the one of metabolites (reduction form of nicotinamide adenine dinucleotide, NADH) can be adopted as a vitality indicator of the bacteria. This signal was chosen as an analytical signal. It was determined that the nature of this signal is fluorescence. In order to eliminate influence of the light scattering on this fluorescence signal optimal conditions were chosen
