Opis:
Quantities of improvised explosive devices on a base of industrial explosives that were applied at criminal incidents or were withdrawn from illegal circulation were reduced on average on 9% during last decade. This tendency is explained in particular by toughening of control under circulation of commercial explosive devices. The most commonly used improvised explosives according to returns of The Forensic Science Center of Ministry of Internal Affairs are mixtures on a base of ammonium nitrate with organic fuels and aluminum powder. Quantitative and qualitative compositions of such improvised mixtures can be various. The most essential question for a criminal case investigator is argument that excepted substance is explosive one. In this connection detonability of the mixtures on base fne (particle size was near 20 microns) and granulated ammonium nitrate with some organic fuels and aluminum powder was experimentally investigated. Failure detonation diameters of systems were measured experimentally.

Opis:
Some of pe roxide s : t r i a c e tone t r ipe roxide (TATP) , hexamethylenetriperoxidediamine (HMTD) have been used recently as "irregular" explosives for delinquency and international terrorism purposes. The intimate knowledge of properties and methods of analysis of these substances is necessary for experts. Forensic investigations of some peroxides explosives: triacetonetriperoxide (TATP) and hexamethylenetriperoxidediamine (HMTD) were carried out in this work. The detonation process of peroxides initiation by means of pyroxylin layer ignition was investigated, velocity of detonation at apparent density (ρ HMTD = 0.38 g/cm3, ρ TATP = 0.47 g/cm3) was measured by means of a Russian fotoregister GFR-3. These data were compared with literature detonation velocity values that had been measured at larger densities. The values of detonation velocities complement each other rather well, linear dependencies of D vs. ρ found at densities ρ = 0.35-1.2 g/cm3. The high sensitivity of the investigated analytical methods, that were applied (10-5 -10<-8 g) facilitate the determination of possible times for finding traces of TATP after an explosion. Time t = 6 hours after explosion is the critical time for finding peroxides traces of TATP on a metal surface by means of analytical methods used in this work.

Opis:
Accurate and timely flash floods forecasting, especially, in ungauged and poorly gauged basins, is one of the most important and challenging problems to be solved by the international hydrological community. In changing climate and variable anthropogenic impact on river basins, as well as due to low density of surface hydrometeorological network, flash flood forecasting based on “traditional” physically based, or conceptual, or statistical hydrological models often becomes inefficient. Unfortunately, most of river basins in Russia are poorly gauged or ungauged; besides, lack of hydrogeological data is quite typical. However, the developing economy and population safety necessitate issuing warnings based on reliable forecasts. For this purpose, a new hydrological model, MLCM3 (Multi-Layer Conceptual Model, 3rd generation) has been developed in the Russian State Hydrometeorological University. The model showed good results in more than 50 tested basins.

This article focuses on an investigation of the optical initiation of the light-sensitive energetic complex perchlorates 3(5)-hydrazino-4-amino- 1,2,4-triazole copper(II) perchlorate and 1-H-5-hydrazinotetrazole mercury(II) perchlorate. It is shown that light emission initiates an explosion in energy-rich formulations (compositions) based on these complexes, EC-1 and EC-2 respectively. It was found that the pyrotechnic formulation EC-2 containing the mercury complex may be used to initiate detonation in highly energetic materials.

Opis:
Comprehensive investigations of the Svisloch River phytoplankton were performed in 2006-2010. Samples were taken all-the-year-round at four sites: reservoirs Drozdy and Lake Komsomolskoye, sites along Vaneyev and Aranskaya streets (within the Minsk municipal section of the river). Species diversity of planktonic cyanobacteria and their contribution to phytoplankton abundance and biomass were determined. Potentially toxic cyanobacteria were detected based on the results of molecular-phylogenetic analysis. They contained a microcystin synthesis gene (mcyE). Obtained sequences belonged to the Microcystis and Anabaena genera, which were the most common in reservoirs worldwide and the most frequent agents of blooms. Several types of microcystins and a nontoxic peptide Oscillamide Y were detected in phytoplankton samples by means of LC/MS
В течение 2006-2010 гг. проводилось комплексное исследование фитопланктона р. Свислочь. Пробы отбирались круглогодично на четырех станциях в черте г. Минска: в зарегулированных водохранилищах Дрозды и Комсомольское озеро и на речных уча- стках в районе улиц Ванеева и Аранская. С помощью световой микроскопии определен видовой состав планктонных цианобактерий, оценен их вклад в численность и биомас- су фитопланктона. В результате молекулярно-филогенетических исследований выявле- ны потенциально токсичные цианобактерии, содержащие ген синтеза микроцистина (mcyE). Полученные последовательности принадлежат представителям родов Microcystis и Anabaena (= subg. Dolichospermum), которые широко распространены в водоемах мира и являются частыми возбудителями токсичных цветений. Несколько типов мик- роцистинов и нетоксичный пептид осцилламид Y были детектированы в пробах фито- планктона с помощью ВЭЖХ-МС.

Opis:
The analysis of work of joints of tractors of models DT-YT allows to make the conclusion about presence of breakages because of low constructive strength and not correct definition of parameters of details. Probes of breakages of joints shows that today at designing of joints there is no system of the account of a mode of behavior and joint life cycle. Designing of threaded connections of automobile and tractor technics should be carried out taking into account modes and duration of operation of the car on these modes. Designing of threaded connections is carried out taking into account operation and life cycle modes. It is offered to carry out calculation taking into account accumulation of fatigue damages to a current of set time of operation. For definition of parameters of fatigue strength the technique of the accelerated tests is offered. The technique allows to define parameters of fatigue strength which it is necessary to use in calculations threaded connections. In work probes of a tension of joint of a driving wheel of a Caterpillar, are resulted by a method of the is finitely-element analysis. For probes settlement models are offered and tested. Settlement models allow to simplify construction of geometrical model for use in computer programs and calculations. Using the described technique of designing it is developed construction a retainer screw with a special thread.

Electromagnetic waves generated by the Heusler alloy $Ni_{2.14}Mn_{0.81}GaFe_{0.05}$ at structural phase transition was detected in the frequency range of 28-32 GHz. Influence of the kinetics of phase transitions on the nature of the sample millimeter radiation was studied as well. It has been observed that the contribution of the intrinsic radiation increases with increasing of the heating/cooling rate. The possible mechanisms and theory of such effect is discussed. It is shown that the maximum radiation intensity should be emitted in direction perpendicular to the movement of interphase boundary.

X-ray diffraction, micro-Raman and the Fourier transform infrared spectroscopies as well as magnetometry measurements were performed on nanosized manganese oxides to probe their phase composition and magnetic properties. It was shown that the XRD method is less sensitive to phase composition of manganese oxide samples than spectroscopic methods. While in some samples the XRD method recognised only the manganosite MnO phase, the Raman and FT-IR methods revealed additionally the presence of the hausmannite Mn₃O₄ phase.
