THE METHODOLOGY FOR THE SYNTHESIS AND CORRECTION OF THE "RISK PYRAMIDS" IN THE AIRPLANE SEGMENT OF COMMERCIAL AVIATION OF RUSSIA
Authors: Guziy A. G. , Lushkin A. M. , Fokin A. V. 
Published: August 2018

The article presents the results of the "risk pyramids" analysis of commercial aviation for their adequacy to the current state of the aviation transport system of Russia. The necessity of annual updating of "risk pyramids" is shown, as the aviation transport system (ATS) of Russia is dynamic and the ATS state changes faster than the accident rate statistical indicators characterizing this state. The method of linear weighted moving average for the synthesis and annual correction of the "risk pyramids" parameters with an optimized averaging coefficient – 7 years is substantiated and proposed. The optimization of the averaging coefficient is performed by the criterion of the minimum mismatch between the averaged values of the "risk pyramids" parameters and the current (annual) values determined by the statistical data of an aviation events. The general and private "risk pyramids" of commercial aviation of Russia synthesized by results of the statistical factorial analysis of aviation events for 2009–2016 are presented. The synthesis of "risk pyramids" is made in accordance with the classification of aviation events in the civil aviation of Russia, separately by causative factors: "Human", "Aircraft", "Environment". The parameters of the "risk pyramids" reflect the conditional probability of an aviation event of great severity (for example, a catastrophe), if there were aviation events of less severity (for example, incidents). The parameters of the presented pyramids are intended for inclusion into the algorithms of indirect estimation of probability of aviation accidents for any airline and any period of flight work (from a month or more).

Published: August 2018

An analysis of the literature and an essay on the problem of recognizing the diseases of workers — diagnosis and causation(work-relatedness assessment) are given. A historical reference is made on the etiology of workers’ diseases and the statements of the classics about the causality in medicine. The main categories of occupational medicine and terminology of the WHO and ILO, the principles of evidence in occupational health are considered. The WHO concept of work-related diseases (WRD), occupational disease (OD) recognition systems under ILO Convention No. 121, features of the ILO occupational diseases list (revision 2010), and the criteria for inclusion of diseases in this list are presented.The general provisions of causation, types of causation algorithms in consensus and evidence-based medicine, as well as a generalized algorithm for analyzing periodic medical examinations data are considered. The European experience of recognition of WRD is considered. Based on experience and literature data, we propose a 10-step causation algorithm, including forecasting the probability of OD and WRD, as well as quantifying the degree of work-relatedness with computer support programs from the electronic directory «Occupational Risk» (http://medtrud. com/). It is concluded that legal recognition of WRD is needed for early diagnosis and prophylaxis of workers’ health disorders in conditions of digitalization of the economy and society.

Published: August 2018

Abstract
The influence of Q-switched pulsed Nd:YAG laser interference heating, using 120 mJ of pulse energy and a variable number of consecutive pulses, on the microstructure and magnetic properties of amorphous Fe80Si11B9 alloy was examined. Microstructural analysis, using light, scanning and transmission electron microscopy, was complemented by results of Mössbauer spectroscopy and measurement of magnetic properties (vibrating sample magnetometer). Periodically distributed crystallized micro-areas, ∼10 μm in diameter, in an amorphous matrix were produced by the treatments. Magnetization measurements showed that the as-cast ribbon and laser light irradiated samples are magnetically soft materials. The results lead to the conclusion that the dots corresponding to the laser modified regions exhibit a perpendicular magnetic anisotropy.

Authors: Hu Yong , Zhao Longzhi , Liu Dejia , Tang Yanchuan , Jiang Hui 
Published: August 2018

Abstract
Semi-solid billets of A356 alloy were fabricated using a sloping-plate device. This study investigated the effects of reheating on the microstructural evolution of the alloy. Prolonged holding times and higher reheating temperatures caused the primary α-aluminum particles to gradually grow and spheroidize, resulting in increased liquid fraction. The optimal reheating condition was 580°C for 25 min, during which the average grain size increased to 89.3 μm and the shape factor reached 1.18. The secondary phases were also refined by the reheating process.

Published: August 2018

Abstract
In this work, we present the synthesis of SBA-15 materials modified with 6 and 9 mol.% of Zr and P, respectively. Silanol SBA-15 groups were detected by Fourier transform infrared spectroscopy. X-ray diffractograms revealed that the typical hexagonal arrangement of SBA-15 was preserved after Zr and P introduction, and the structure was confirmed by transmission electron microscopy. After the Zr introduction, the morphology of SBA-15 changed from fibrous particles to a semi-spherical shape according to scanning electron microscopy, while nitrogen physisorption revealed the stability of the textural materials after the P introduction. The infrared spectra of pyridine adsorption indicated that the Zr and P incorporation into SBA-15 generated adequate Lewis and Br⊘nsted acidities to carry out methanol dehydration and direct the selectivity towards dimethyl ether, with medium-strong acid sites being responsible for obtaining up to 99% selectivity towards dimethyl ether.

At a spatial resolution of 0.″2 and a spectral resolution of 40 km s−1, the source is resolved into three distinct components, which are spatially and dynamically associated within a projected radius of 20 kpc and a radial velocity range of 2000 km s−1. For two major components, our Bayesian-based tilted-ring modeling of the ALMA spectral cubes shows almost flat rotation curves peaking at ∼500 km s−1 at galactocentric distances between 2 and 5 kpc. Each of them has a dynamical mass of ∼1011
