FLIGHT SAFETY CONTROL OF THE BASIS OF UNCERTAIN RISK EVALUATION WITH NON-ROUTINE FLIGHT CONDITIONS INVOLVED by E. A. Kuklev

“…However, for the events such as accidents and disasters, accidents with the aircraft, fighters in a training flight, during the preparation of the pilots on the training aircraft, etc. there is no required statistics. Density of probability distribution (p. d. f.) of these events are only hypothetical, unknown with "hard tails" that completely eliminates the application of methods of confidence intervals in the traditional approaches to the assessment of safety in the form of the probability analysis.…”

Inhibitory effects of probucol on the transition of human renal proximal tubular epithelial cells induced by Ox-LDL and exploration of its related mechanisms by ZHU Bing-bing, CHI Yang-feng, WANG Hao, LIU Yu-jun, WANG Yun-man, PENG Wen

“…Objective To study the inhibitory effects of probucol on the transition of human renal proximal tubular epithelial cells(HK-2) induced by oxidized low-density lipoprotein(Ox-LDL),and to explore the role and interrelation of lectin-like oxidized low-density lipoprotein receptor-1(LOX-1) and oxidative stress.Methods HK-2 cells were cultured and pretreated by different dosages of Ox-LDL(0-100 μg/ml) in vitro with probucol(20 μmol/L) and LOX-1 inhibitor polyinosinic acid(250 μg/ml).Cell proliferation was measured using MTT assay.Activity of reactive oxygen species(ROS) was evaluated using DCFH-DA method.Concentration of nitric oxide(NO) was determined using biochemical colorimetric method.The expression levels of protein E-cadherin,α-SMA,LOX-1and NADPH oxidase 4(NOX-4) were examined using Western blotting.Results There was no significant influence of Ox-LDL(12.5~200 μg/ml) on the proliferation of HK-2 cells,however,OxLDL(25~100 μg/ml) could induce the expression of LOX-1 and α-SMA proteins,while E-cadherin declined simultaneously in a dose-dependent manner.Polyinosinic acid and probucol could inhibit the expression of LOX-1 protein as well as α-SMA protein,while the expression of E-cadherin increased.50 μg/mL Ox-LDL could induce the expression of NOX4 protein as well as intracellular ROS activity(451.5 μg/ml vs.839.8 μg/ml,P<0.05),while the concentration of cell supernatant NO increased slightly with no significant influence(46 μmol/L vs 46.2 μmol/L).However,the increases of NOX4 protein and ROS activity were inhibited by polyinosinic acid and probucol,while the concentration of NO barely changed.Conclusions Ox-LDL could induce the transition of human renal proximal tubular epithelial cells probably through the oxidative stress by the receptor LOX-1.However,probucol and the LOX-1 inhibitor polyinosinic acid could inhibit the injury of oxidative stress by reducing the expression of LOX-1,and delay the process of epithelial to mesenchymal transition.…”

Evaluation of material parameters, texture and stress of a prestressed polycrystalline aggregate from ultrasonic measurements by J. LEWANDOWSKI

“…Moreover, the use is made of Jaynes' principle of maximum Shannon entropy and the averaging procedure proposed by Voigt. In this way, the probability density function of the crystallite orientation (texture) and the effective stiffness moduli of a single crystallite of the polycrystalline aggregate are evaluated numerically for the initial plane stress increasing from zero up to about 300 MPa (in the range of elasticity). …”
