This paper presents a dendroclimatic analysis of Siberian larch trees sampled along a latitudinal 260-km transect located in the Polar Urals,Russia. Three standardised chronologies were built ov.r a length of 230–293 years using 79 indiv.dual tree-ring chronologies collected in the southern,middle and northern parts of the Polar *** correlation functions showed that the annual growth of the larches was mainly influenced by the air temperatures in June and July. The relativ. role of the temperatures increased from south to north. Daily air temperature data analysis rev.aled that the duration of the growing season in the northern part of the Polar Urals is 24 days less than that in the southern part. At the present time, air temperatures exceeded threshold of 8~℃, 5 days earlier than it did in the beginning of the 20 th century In response to the increase in the duration of the growing season and the changing winter conditions in the Polar Urals ov.r the last 130 years, radial growth–temperature relationships in larches hav. weakened;this effect was strongly pronounced in the southern part of the Polar Urals.

The paper proposes a methodological scheme that thoroughly accounts for natural-climatic conditions which can impair the stability and longev.ty of transport facilities （roadways）, to ensure the best possible quality of the initial road design. Factors determining the formation of water-heating mode subgrade soils are allocated, and an information database for mathematical modeling of geocomplexes is shown. v.lues of strength and deformability of clay soils are calculated within the limits of the defined, homogeneous road districts in Western Siberia to prov.de the required lev.l of reliability of design solutions.

The effect of complete social depriv.tion in early postnatal ontogenesis on adult behav.or in Wag/Rij rats with a genetic predisposition to the dev.lopment of absence epilepsy was studied. From the 2nd to the 8th day of life, a 3-hour daily isolation of the pups from the mother and siblings was performed, the control animals were handled. In adulthood, offspring behav.or was tested in an elev.ted plus-maze, an open field, and for an ability to learn the conditioned reflex of activ. av.idance. In isolated earlier rats, an increase in emotional reactiv.ty, exploratory behav.or in a potentially dangerous space, the speed of learning a conditioned reflex with negativ. painful reinforcement, and a disturbance of the formation of a defensiv. reaction were rev.aled. It is assumed that high emotional reactiv.ty creates the prerequisites for the dev.lopment of absence epilepsy.

The effect of a quartz plate (window) on the silicon wafer temperature is studied in the conditions of the combined thermal transfer in a lamp-based chamber for the rapid thermal treatment (RTP) set up. The chamber for RTP is simulated by a radiativ.-closed thermal system including the influence of quartz window as a spectral filter of lamp emission and a source of emitted thermal radiation. Energy equations for thermal fluxes inv.lv.d in the heat input and output from the working wafer and quartz window are solv.d in spectral approximation. The transfer characteristics that are defined by the temperature dependencies of the silicon wafer and the quartz window on the temperature of the heater are accounted. It is shown that temperature bistability in the silicon wafer initiates an induced bistability into the quartz window that does not rev.al bistable behav.or because of the linear temperature dependence of its total optical characteristics. A possibility for simulation of the quartz window by spectral restriction of the heater radiation is confirmed. The av.ilability of the weak bistable effect in the mode of zero effectiv. heat exchange coefficient of a non-radiativ. component of the thermal flux remov.d from the working wafer has been obtained.

A new type homogeneous planar PC （photoelectric conv.rter） on the basis of multijunction semiconductor n＋-p-p＋-n＋-p-p＋-...-n＋-p-p＋ structure has been inv.stigated. The entire structure is a cascade PC consisting of a number of elements of the structure--single PCs connected in series and illuminated by light that has consistently passed through the prev.ous semiconductor layers. The theory of conv.rter of both monochromatic and solar radiation has been dev.loped and the limiting v.lues of their photoelectric and power characteristics hav. been determined, including the optimal thickness and number of single PCs layered on a base PC, their spectral sensitiv.ty, current-v.ltage characteristics and efficiency. The open-circuit v.ltage grows practically linearly with the number of elements in the cascade. The top efficiency limit for a certain optimal elements number reaches its maximum that exceeds considerably that of the base PC, especially in the range of low collecting coefficient of charge carriers in the base PC.

AIM: To study antibiotic resistance patterns and susceptibility to eye antiseptic picloxydine of conjunctiv.l flora in patients undergoing intrav.treal injections(Iv.s).METHODS: Conjunctiv.l swabs were taken in 4 groups of patients, 20 patients in each group(n=80): without Iv.s and ophthalmic operations in history(group N1;control group);with the first Iv. and antibiotic eye drops Tobrex applied 3 d before Iv. and 5 d after it(group N2);with 20 or more Iv.s and repeated courses of antibiotic eye drops(group N3);with the first Iv. and antiseptic eye drops v.tabact(picloxydine) applied 3 d before Iv. and 5 d after it(group N4). In groups N2 and N4 swabs were taken at baseline and after the treatment. Efficacy of picloxydine in inhibition of growth of conjunctiv.l isolates susceptible and resistant to antibiotic was studied in v.tro. Minimal inhibition concentrations(MIC) were determined with microdilution ***: Two of the three patients who had to undergo the Iv. procedure showed conjunctiv. bacterial contamination. Along with few Staphylococcus aureus and Gram-negativ. isolates susceptible to most antibiotics, the majority(71%-77%) of causativ. agents were coagulase-negativ. Staphylococci(Co NS), 40%-50% of which were multidrug resistant(MDR). Eye disinfection in the operating room and peri-injection courses of Tobrex or v.tabact resulted in total elimination of isolates found at baseline. Howev.r, in 10% and 20% of patients, respectiv.ly, recolonization of the conjunctiv. with differing strains occurred. In patients with repeated Iv. and Tobrex/Maxitrol treatment, the conjunctiv.l flora showed high resistance rates: 90% of Co NS were MDR. In the in v.tro study, picloxydine showed bactericidal effect against Staphylococci isolates both antibiotic resistant and susceptible with MIC≥13.56 μg/m L. Incubation of bacteria for 15 min in v.tabact eye drops, commercially av.ilable form of picloxydine, 434 μg/m L, showed total loss of colony forming units of all teste
