The expediency of development of one of the newest highly effective radiation-protective materials—layered composites of “light metal/heavy metal” type is substantiated. The characteristics of the internal architecture of composites of Al/Pb type made by consecutive application of vacuum and normal atmospheric rolling are adduced. The differences between the radioisotope and accelerating techniques of experimental testing of radiation-protective properties of materials are described. The results of the testing of composites and the influence of their structure on radiation-protective properties of the investigated materials are characterized. It is shown that the radiation-protective efficiency of composites certain structures may be 30% - 40% higher than the aluminum. This gives the opportunity to reduce the weight of radiation-protective structure at preservation of effectiveness of protection at aluminum level, or to increase the effectiveness of protection at constant weight of this structure.

Dynamics of regional and gender features of occurrence of arterial hypertension associated with diseases of gallbladder, biliary ducts and pancreas for 2003-2011 was analyzed. There researched 23,310 patients (9111 males and 14,188 females) treated in clinic of scientific centre of clinical and experimental medicine SB RAMS. Occurrence of such combination, depending on gender, residence (the Novosibirsk region (NR) or Yakutia) as well as in age subgroups (16-39, 40-59 and over 60) was estimated. Occurrence of arterial hypertension associated with diseases of gallbladder, biliary ducts and pancreas was observed more in male of Subgroup I, living in NR and Yakutia. In 2003-2008 in female of Subgroup III, living in NR comorbidity pathology was observed more frequently than in male. In Subgroup III in female of NR occurrence of combined pathology was maximum (36.6%) 2006-2008, in female of Yakutia—38.5% in 2003-2005. Dependence of occurrence of combined pathology on residence was observed in male. In 2003-2011 in male of Yakutia combined pathology was observed frequently than in male of NR. Occurrence of comorbidity pathology, depending on gender and age was typical for inhabitants of NR. In Group I comorbidity pathology was frequently observed in male, in Group III—in female. It is necessary to develop regional strategies for observing patients with combined pathologies to improve prevention, rehabilitation and treatment of patients with arterial hypertension associated with diseases of gallbladder, biliary ducts and pancreas.

研制基于超声速燃烧的高效吸气式推进装置(运行Mach数在3.5以上)需要寻求改善混合效率的有效机制,这对于采用常规碳氢燃料(特别是可以增加密度的液体燃料)的装置尤为重要.延长混合时间的一种途径是在飞行器燃料室的上游喷入部分燃料.壁面喷射一直是超声速气动力学最具挑战性的课题,这里包括使比冲损失最小、改善燃料-空气的混合、减少入口段/燃烧室的相互作用以及增进火焰稳定性等.综述了超声速入口段或燃烧室的隔离器中液体燃料(个别情况下为气体燃料)喷射的研究进展.在这些研究中,燃料都是从后掠型细支架尾迹中的壁面处喷射出来的,动压比很低(q_(jet)/q_(air)=0.6～1.5).它们涉及入口段和燃烧室的隔离器中单个支架/喷射器的几何结构及其组合方式、各种各样的喷射条件、不同的引射剂,并且评估了这些因素对于燃料羽流喷散、比冲损失以及混合效率的影响.述评引用了46篇参考文献.

In bulk granulated cobaltite La1–xSrxCoO3 with the size of granules of order of 1 micron at strontium hole doping with replacement factor x = 0.35, a transition “metal-nonmetal” in the conductivity was revealed, presumably connected with AFM ordering of the moments of granules. The assumption is proved by the agreement between the experiment and results of calculation within the limits of a model offered for electron transport based on the account of in-granule double exchange Zener mechanism and intergranule mechanism of spin-polarized tunneling on the nearest neighbours with AFM exchange interaction. The calculation differs in that conductivities within granules are summarized, while total resistance of the system is represented as a sum of resistances of the granules. In addition, the existence of AFM interaction between granules is supported by the observed insensitivity of conductivity to a low external magnetic field (up to 5 kOe).

The paper is focused on different kinds of gravity results obtained in Shults Cape Observatory for 2010 -2015. Gravity observation is interpreted together with GPS observation data which was obtained from 2012 to 2015 at the same station, The station is situated on Gamov peninsular （42.58° N, 131.15° E, Russia） at the coast of Japan Sea, This region constitutes the eastern boundary of Eurasia. This major continental tectonic feature is associated with a seismic activity, high heat flow and anomalous thickness of earth＇s crust. The goal of the observation was the investigation of gravity variation with time and seismicity situation monitoring. Gravity observation was developed at special basement by absolute gravimeter （GABL type） and by spring gravimeter （SCINREX CG-5and gPhone type）. Tidal models were tested by results of observation with spring gravimeters. Reduction task was solved, as the experimental data received from different points of Shults Cape Observatory was used. Applied reduction coefficient is 203.3 12Gal m l, and agrees with theoretical calculation. Next goal was studying structure of earth＇s crust by means of gravity models. Gravity anomaly varied from 30 mGal to 46 mGal, which also depend on difference reference system, Experimental results were used for testing of the structure of continental boundary, which also depends on the sea bottom flexion. Thickness of elastic layer was estimated from 12 km to 18 km by using different models.
