Analytical support of management activities in the context of management accounting standardization

The development and improvement of national accounting and management accounting is accompanied by the introduction of new methods for analysis and diagnosing the final result. So, the point approach in the management of assets and liabilities involves a quantitative and qualitative characteristic of the resulting economic situations (consequences) in production and financial activities. This does not happen spontaneously, but as the business management system develops.Recently, there has been the increase of interest in the analysis of profitability in relation to different segments of sales, diagnostics of margin indicators, etc

Study of amino acids of the Pyrola Rotundifolia L. and Orthilia Semnda L

The article presents the results of study of amino acid composition of Orthilia secunda L. and Pyrola rotundifolia L. in Eastern Siberia. It was established that studied plants contain 15 nonessential and 9 essential amino acids. Concentration of amino acids in the aboveground part of Orthilia secunda L. was 55,92 mg/g, in the grass of Pyrola rotundifolia L. - 64,02 mg/g. The largest part of amino acids of Orthilia secunda L. and Pyrola rotundifolia L. are similar representatives of this class. Among nonessential amino acids content of glutamic (6,66 and 7,40 mg/g), aspartic acid (3,93 and 4,92 mg/g), glycine (2,96 and 3,43 mg/g) is expressed. Essential amino acids are represented by the following series: leucine - 4,49 and 4,76 mg/g, lysine - 4,19 and 4,30 mg/g, phenylalanine - 3,05 and 3,08 mg/g

Effects of brain renin- angiotensin system inhibition in ISIAH rats with inherited stress-induced arterial hypertension

The renin-angiotensin system (RAS) is one of the main systems regulating arterial pressure and water-salt homeostasis of the body and is involved in the pathogenesis of cardiovascular diseases. Angiotensin peptides – products of enzymatic hydrolysis of angiotensinogen – can be synthesized not only in the blood stream, but also in tissues, including various regions  of the brain. Studies of local tissue RAS in the context of arterial hypertension have been conducted for a long time. It has been shown that a steady arterial pressure increase is often associated with changes in the functioning of the central (brain) RAS in various animal models of hypertensive disease and in humans. Nevertheless, it is still not completely clear whether these changes alone are sufficient for the formation of hypertensive status, and whether the components of the central RAS can be used as targets for the treatment of hypertensive disease. Effects of prolonged inhibition of the brain RAS on blood pressure and expression of RAS genes in brain and kidney tissues in ISIAH (inherited stress-induced arterial hypertension) rats were studied. Inhibition was performed using widely used pharmacological agents, losartan and benazepril. Osmotic minipumps were used to deliver drugs to the lateral ventricle of the brain. It was shown that prolonged inhibition of the central RAS, AT1 receptors in particular, can lead to a decrease in blood pressure and significant changes in the level of expression of brain RAS genes in ISIAH rats. The mRNA level of RAS genes in the kidney does not significantly change due to this inhibition. Thus, the participation of the central RAS in the pathogenesis and maintenance of hypertensive status during stress induced form of hypertensive disease in ISIAH rats was confirmed

Fluctuation-induced phase in CsCuCl3 in transverse magnetic field: Theory

CsCuCl3 is a quantum triangular antiferromagnet, ferromagnetically stacked, with an incommensurate (IC) structure due to a Dzyaloshinskii-Moriya interaction. Because of the classical degeneracy caused by the frustration, fluctuations in CsCuCl3 have extraordinarily large effects, such as the phase transition in longitudinal magnetic field (normal to the planes, parallel to the IC wavenumber q) and the plateau in q in transverse field (perpendicular to q). We argue that fluctuations are responsible also for the new IC phase discovered in transverse field near the Neel temperature T_N, by T. Werner et al. [Solid State Commun. 102, p.609 (1997)]. We develop and analyse the corresponding minimal Landau theory; the effects of fluctuations on the frustration are included phenomenologically, by means of a biquadratic term. The Landau theory gives two IC phases, one familiar from previous studies; properties of the new IC phase, which occupies a pocket of the temperature-field phase diagram near T_N, agree qualitatively with those of the new phase found experimentally.Comment: 12 pages, revtex, 4 postscript figures, submitted to J.

DYNAMICS OF ANTIBIOTIC RESISTANCE OF NOSOCOMIAL PATHOGENS AND STATE OF ANTIBIOTiC THERAPY IN MULTIFIELD CLINIC

We carried out comparative analysis of the results of microbiological researches and antibiotic resistance of main pathogens of nosocomial infections from 2005 to 2010 years. During this period quota of MRSE (65—74 %), MRSA (22,7—35 %) is stably high and. especially quota of producers of different β-lactamases among other Enterobacteriaceae pathogens (3,2—65 %) increased that caused, significant expenses for antibiotic therapy by carbapenems (22,7—40 %), glycopeptides (2,7—10 %). Monitoring of tendencies of resistance of the most important pathogens of hospital infections optimication of antimicrobial therapy and introduction, of the system of preventive measures allowed, to decrease economic expenses for antimicrobial means to 17,5 %
