In the present information presents the results of studies of the effect of dispersion of ammonium perchlorate on the content and nature of the soot formed in the process of burning of butyl-rubber propellants

Modification of fatty acids composition in erythrocytes lipids in arterial hypertension associated with dyslipidemia

<p>Abstract</p> <p>Background</p> <p>Modification of fatty acids (FA) composition in erythrocytes lipids as an early indicator of the development of arterial hypertension (AH) and lipid disorders.</p> <p>Methods</p> <p>We included 34 patients with arterial hypertension and 11 healthy individuals. Each patient was examined the lipid composition of serum. From erythrocytes by gas chromatography were identified fatty acids. The quantitative composition of the erythrocyte lipids FA in patients with AH presented with saturated and polyunsaturated monoenic acids with carbon chain lengths from C12 to C22.</p> <p>Results</p> <p>In all hypertensive patients is disturbed lipid FA composition of erythrocytes. The patients with a normal level of serum lipids revealed deficiency of polyunsaturated acids n6-linoleic (18:2 n6), arachidonic (20:4 n6), dokozatetraenic 14,4% (22:4 n6). The patients with dislipidemia installed more profound restructuring of the lipid matrix of the membrane of erythrocytes. A decrease in polyunsaturated fatty acids family n3: dokozapentaenovoy (22:5 n3), docosahexaenoic PUFA (22:6 n3), the total value of n3 PUFA in 1,3 times was revealed.</p> <p>Conclusion</p> <p>Thus, modification of erythrocyte FA are fairly subtle indicator of pathology of lipid metabolism, which manifest themselves much earlier than changes in the lipoprotein of blood plasma.</p

Global data set of long-term summertime vertical temperature profiles in 153 lakes

Climate change and other anthropogenic stressors have led to long-term changes in the thermal structure, including surface temperatures, deepwater temperatures, and vertical thermal gradients, in many lakes around the world. Though many studies highlight warming of surface water temperatures in lakes worldwide, less is known about long-term trends in full vertical thermal structure and deepwater temperatures, which have been changing less consistently in both direction and magnitude. Here, we present a globally-expansive data set of summertime in-situ vertical temperature profiles from 153 lakes, with one time series beginning as early as 1894. We also compiled lake geographic, morphometric, and water quality variables that can influence vertical thermal structure through a variety of potential mechanisms in these lakes. These long-term time series of vertical temperature profiles and corresponding lake characteristics serve as valuable data to help understand changes and drivers of lake thermal structure in a time of rapid global and ecological change

Improving the Calculation of the Efficiency Assessment of Cash Flow Management in High-Tech Industries

Relevance: Information about cash flows is always being closely monitored by analysts, business managers and investors. The efficiency of money management determines the quality of the entity as a whole. And his management should use the integrated indicator of the effectiveness of cash flow management in making management decisions.The novelty of the present scientific research is in the following:- the advanced method of calculation of the integral indicator of the efficiency of cash flows management at the high-tech enterprises is proposed,- the appropriate and efficient use of cash flow profitability indicators is identified.Practical usefulness.- It is justified that The Net Present Value (NPV) profitability of net cash flow is the indicator that reflects the efficiency of cash flow management.- The proposed integral indicator of the effectiveness of cash flow management makes it possible to determine the impact of individual factors that influence the formation and use of NPV.- the proposed efficiency assessment for effective cash management will determine the quality of management of activity of the economic entity
