Methodological issues of mechanism accuracy computation under the nonlinear correlation of primary errors

Specific issues of providing a computational basis for the accuracy of mechanisms with interdependent primary errors are considered. It is shown that in the presence of a nonlinear correlation, a number of common theses of accuracy theory require certain modifications, since they do not fit in the standard approaches to the computation of kinematic chain accuracy.     

Excess enthalpy data for the ternary system methane—ethylene—carbon dioxide by flow calorimetry

Excess enthalpy data for the ternary system methane – ethylene – carbon dioxide was obtained utilizing an isothermal flow calorimeter. The measurements were made at three temperatures: 293.15, 305.15 and 313.15 K and pressures of 1.114, 1.520 and 3.445 MPa (11, 15 and 34 atm). The determination of excess enthalpies for the binary systems methane—ethylene, ethylene—carbon dioxide and methane—carbon dioxide has been reported in three preceeding articles, respectively: Gagné et al., 1985; Ba et al., 1979 and Barry et al., 1982a. The binary interaction coefficients k_ij obtained for these systems have been utilized as initial values for the optimization procedure leading to the k_ij for the ternary system. For the case of the ternary system studied in this investigation, two types of binary interaction coefficients k_ij have been determined from experimental data: k_ij independent of temperature and pressure and k_ij adjusted as function of temperature and pressure. Experimental data were compared with the predictions from Benedict—Webb—Rubin and Redlich—Kwong equations of state. In both cases, the coefficients k_ij dependent on temperature and pressure led to better prediction of excess enthalpies.     

Dietetic canned food using ocean fish and plant components

The results of the creating canned ground goods of a new kind are described in this article. The main character references of food value of hake and the canned ground foods based on it. It has been established that the new products of safety. Clinical tests have been showed the efficiency of including these canned goods in the menu of fat patients, also with heavy obesity. Dietetic canned ground foods on the base of oceanic fishes with plant additives.     

Study of fatty acid composition of cell membranes during the use of soya oil in diet therapy of patients with cardiovascular diseases

Anti-atherogenic diet supplemented with 20 g soy oil has been analyzed in patients with coronary artery disease and high blood pressure. The vegetable PUFA omega-3 and omega-6 from soy oil have been found to change physical, biological and chemical property of membranes; improved clinical condition as well as to modify erythrocyte membrane fatty acid composition.     

汽车电池管理市场是否已准备好标准化?

不断变化的BMS要求正在推动CVM IC供应商进行大量的开发工作.同时,缺乏标准接口使OEM和电池系统制造商很难更换CVM IC供应商.不同的OEM厂商总是会有不同的需求,因此基于模块和基于单元的BMS方案将并存,有线或无线以及有无微控制器.如果将第二次使用的要求考虑在内,并选择一些标准的BMS内部接口,则投资效率将会...
