Представлена разработанная теоретическая модель одномерной неоднородности (МОН) и описаны основные факторы, влияющие на распределение вектора намагниченности тонкого магниторезистивного элемента анизотропного магниторезистивного преобразователя (АМРП). Получены результаты расчета вольт-эрстедных характеристик АМРП с помощью МОН, которые согласуются с экспериментальными данными. The developed theoretical model of one-dimensional heterogeneity (MODH) is presented. Described are the main factors affecting distribution of a thin magnetoresistive element magnetization vector of an anisotropic magnetoresistive transducer (AMRT). The calculated results of AMRT volt-oersted characteristics obtained using MODH are consistent with the experimental data.

The article presents the results of studies of the fatigue strength of A500 class reinforcement by GOST 34028-2016 with various types of periodic profile. The data on the results of previously conducted experimental studies of the fatigue strength of various types of reinforcement are generalized and systematized, and the main factors affecting fatigue are established. Experimental data on strength and deformation characteristics under static and high-cycle loads of A500C class reinforcement with various types of periodic profile have been obtained. Based on the research results, proposals were made to improve the characteristics of the reinforcement and the periodic profile to increase its resistance to repeated cyclic loads and to amend the current regulatory documents.

The paper deals with the possibility of preparing a mixture of 1,3-dialkylimidazole salts from commercially available reagents via multicomponent condensation. Main factors affecting the yield of the target product, as well as the obtained experimental data needed for scaling-up the process are discussed. It is shown that the prepared mixtures are close in some key properties (viscosity at different temperatures, heat capacity etc.) to the pure salts. The possibility of the application of the prepared salts as solvents for catalytic hydrodechlorination and catalyst components for alkylation of aromatic compounds is demonstrated.

Good Agreement

The problem of obtaining adequate aerodynamical boundary conditions for an analyzed blade is important to predict resonant stresses. According to this, three different CFD approaches of stator-rotor modeling have been investigated for obtaining gas dynamic loading: 1. 3D averaged and then quasi-3D unsteady calculations. 2. Fully 3D unsteady calculations using commercial CFX solver. 3. Fully 3D unsteady calculations using the in-house solver. To carry out 3D structural analysis the ANSYS software and our subroutines have been applied. The methodology to estimate damper ratio for the different mode shapes and mode numbers has been developed. As a result, the tools to predict the resonant stress have been created where we tried to take into account all main factors affecting resonant stress level. The HPT first stage blade of a modern aircraft engine was chosen as an example of using our tools for prediction of resonant stresses level. A comparison of experimental data and obtained calculation results showed good agreement.

ABSTRACTThe geographic position, astronomic factors (e.g. the Earth’s maximum distance from the Sun during winter), ice cover and altitude are the main factors affecting the climate of the Antarctic, which is the coldest place on Earth. Parts of Antarctica are facing the most rapid rates of anthropogenic climate change currently seen on the planet. Climate changes are occurring throughout Antarctica, affecting three major groups of environmental variables of considerable biological significance: temperature, water, UV-B radiation.Low diversity ecosystems are expected to be more vulnerable to global changes than high diversity ecosystems

Formation of gas hydrates under shock wave impact on bubble media (two-dimensional case) The dynamics of plane one-dimensional shock waves applied to the available experimental data for the water–freon media is studied on the base of the theoretical model of the bubble liquid improved with taking into account possible hydrate formation. The scheme of accounting of the bubble crushing in a shock wave that is one of the main factors in the hydrate formation intensification with increasing shock wave amplitude is proposed.

Abstract:: Thanks to their excellent corrosion resistance, superior mechanical properties and good biocompatibility, titanium (Ti) and Ti alloys are extensively applied in biomedical fields. Pitting corrosion is a critical consideration for the reliability of Ti and Ti alloys used in the human body. Therefore, this article focuses on the pitting corrosion of Ti and Ti alloys, which introduces the growth stages of pitting corrosion and its main influencing factors. Three stages, i.e. (1) breakdown of passive film, (1) metastable pitting, and (3) propagation of pitting, are roughly divided to introduce the pitting corrosion. As reviewed, corrosive environment, applied potential, temperature and alloy compositions are the main factors affecting the pitting corrosion of Ti and Ti alloys. Moreover, the pitting corrosion of different types Ti alloys are also reviewed to correlate the types of Ti alloys and the main factors of pitting corrosion. Roughly speaking, β-type Ti alloys have the best pitting corrosion resistance among the three types of Ti alloys.

The COVID-19 pandemic has had an unprecedented impact on the labor market. The psychological pressure and uncertainty caused by the current changing workplace environment have led to negative consequences for workers. Considering the predictive relationship between employee engagement and wellbeing and in light of this unprecedented situation that affects workers of all the industries worldwide, this study aims to identify the key main drivers of employee engagement that can lead to employee wellbeing in the current context. Through a literature review, a theoretical model to strengthen engagement in times of COVID-19 is proposed. The main factors are conciliation, cultivation, confidence, compensation, and communication. Whereas prior to the pandemic, firms had already understood the need to achieve this, it is now considered a vital tool for staff health and wellbeing. This article makes two main contributions. First, it provides a model for boosting employee engagement, and therefore, wellbeing. Second, managerial suggestions are made to apply the theoretical model.

Using Data

Professional football clubs have a special characteristic not shared by other types of companies: their sport performance (on the field) is important, in addition to their financial performance (off the field). The aim of this paper is to calculate an efficiency measure using a model that combines performance (sport and economic) based on data envelopment analysis (DEA). The main factors affecting teams’ efficiency levels are investigated using cluster analysis. For a sample of Spanish football clubs, the findings indicate that clubs achieved a relatively high efficiency level for the period studied, and that the oldest teams with the most assets had the highest efficiency scores. These results could help club managers to improve the performance of their teams.

The aim of this study is to evaluate the potential of dried Cystoseira barbata alga for ethanol production through alcoholic fermentation. The influence of the main factors affecting the fermentation are studied in the frame of a 23 factorial experimental plan. The main factors influencing the process are the fermentation temperature (t from 25 °C to 35 °C), the solid to liquid ratio (S/L from 0.040 g/g to 0.080 g/g), and the cellulase ratio (R from 8 U/g d.m to 16 U/g d.m.). The maximum volatile compounds yield of 0.2808 g/g d.m and ethanol yield of 0.0158 g/g d.m were favored by the following experimental conditions: process temperature of 35 °C, solid to liquid ratio of 0.0415, and enzyme ratio of 16 U/g d.m. A statistical model was used to correlate the product yield with the process factors. Additionally, 19 interesting bioactive compounds were found in the enzymatic hydrolysis and alcoholic fermentation broths which seem likely to maintain natural defence mechanisms against diseases and physical disorders.
