Abstract
Supply chain is a group of companies that work together to create and deliver products to end users [7]. Whereas supply chain risk is defined as an imbalance between demand and supply. Supply chain disruptions can cause various problems such as length of waiting time, out of stock, inability to meet customer demand, and rising costs [1]. If supply chain risk occurs, it will certainly cause material and non-material losses. To anticipate this loss, proper supply chain risk management is essential. In this study, the author developed [11] research entitled “Risk Management Analysis Using FMECA and ANP Methods in the Supply Chain of Wooden Toy Industry”, IOP Conference Series: Materials Science and Engineering, 2019 “The development carried out by the author is” Risk Assessment User Interface Design’s by using Object Orientation Programming Approximation in Wooden Toys Industry” aims to build information systems so that users more easily determine the greatest risk in the company and can minimize the impact of risks that may occur so that it is more effective and efficient . There are 6 risk factors with 25 risk variables from the data questionnaire results [11] and the biggest risk factor is eviroment with marcoeconomic variable risk of 518, 778.
Oxide composite fibers with quasiplastic components and composites with brittle matrices on their basis
Authors: Kiiko V M 
Published: May 2020

Abstract
By the internal crystallization method oxide composite fibers containing high-strength sapphire and hexaaluminates of calcium, lanthanum or barium are obtained. The presence of “weak” planes in the layered structure of hexaaluminates provides cracks inhibition. The dependences of the ultimate strain (strength) of the fibers of these compositions on the length are obtained. The positive effect of such fibers was evaluated on composites with brittle matrices of recrystallized molybdenum and nickel-aluminum intermetallic. The fracture toughness of composite materials with such fibers significantly exceeds the fracture toughness of composites with sapphire fibers. The composites were tested in the temperature range of 20– 1400 °C and showed non-brittle behavior under load, and their strength and fracture toughness correspond to the requirements for structural materials of this kind. The structure of fibers and composites was also studied by electron microscopy.

Abstract
Elastomeric silicone composites with ferromagnetic filler are investigated. The distribution of carbonyl iron filler in the polymer matrix by scanning electron microscopy is visualized. Using atomic force microscopy the magnetostrictive characteristics of these materials are established. 57Fe nuclei hyperfine parameters of the iron filler atoms in the composites are determined by Mössbauer spectroscopy. The influence of the filler microparticles restructuring in external magnetic fields on the composites properties is discussed. The prospects for creating new materials and devices based on the characteristics of such magnetically active elastomers are revealed.

Published: May 2020

Abstract
This study is devoted to wearing resistance of MAO-coatings formed on aluminum alloys 2024 (Al-Cu-Mg) and 7075 (Al-Zn-Mg-Cu) at the friction in pair with steel 100Cr6 in environmentally safe lubricants and represents a generalization and analysis of tests’ results. Investigations were conducted using two methods: reciprocating sliding on the “ball-on-disk” friction scheme and unidirectional sliding on the “pin-on-disk” friction scheme. As environmentally lubricants were used some base oils like polyalphaolefin (PAO), polyethylene glycol (PEG), Silicon Oil, perfluorinated polyether (PFPE) and diisotridecyl adipate ether (DITA). Tests on the first friction scheme allowed us to determine the maximal value of load for investigated friction pairs and tests on the second friction scheme showed their antifriction properties in different lubricants and in the mode of the greasing starvation. There was revealed that MAO-coatings formed on alloy 7075 at high contact pressures demonstrate a friction coefficient lower than on alloy 2024. Some problems of the used “pin-on-disk” scheme is discussed also for improving the tests’ results data.
Application of magnetic units for intensification of water treatment
Authors: Golubev I A , Suprun I K 
Published: May 2020

Abstract
The article investigates the main problem of the standard water treatment system which requires high consumption of reagents and the need to systematically select the optimal dosage (depending on the changeable environmental conditions). The proposed technology of magnetic-reagent treatment of water allows intensifying the stage of reagent treatment. With the implementation of this technology the costs for the reconstruction of the object will not be significant. Bench and test-industrial tests at oil contaminated and drinking water treatment facilities showed the effectiveness of the proposed method, caused by a decrease in time of gravitational separation of coagulated globules and a reduction in the reagent consumption. It is shown that the proposed technology can be considered both as an upgrade of existing water treatment stations operating under a typical scheme, and in the design of new facilities.

Published: May 2020

Abstract
Variation of surface tension coefficient σ of distilled water under high-energy impact (hydrodynamic cavitation) was studied by the ring separation method. Force impacts on surface tension of water have been studied experimentally. Conditions have been found under which the surface tension coefficient σ decreases to 20%. The paper explains the produced results on the basis of cluster theory of water structure. The experimentally produced relaxation time of the surface tension of cavitation-activated distilled water to initial value has been found to be 3.5 hours.

Authors: Zavoruev V V , Zavorueva E N 
Published: May 2020

Abstract
Measurement of temperature, pressure and concentration of particulate matter (PM2.5) in the surface layer of the atmosphere of the village of Drokino was performed using the CityAir air monitoring station. Air pollution occurs due to the burning of brown coal in the stoves of rural houses in winter. Air pollution is caused by smoke from forest fires in the summer of 2019. The average annual concentration of PM2.5 in 2019 was 31 μg/m3 and exceeded the hygiene standard by 1.24 times. It was shown that the concentration of PM2.5 increases with increasing atmospheric pressure and lowering air temperature. It was established that the PM2,5 concentration exceeds 3.00-4.49 times the hygiene standard established for the atmosphere of populated areas during periods of anticyclone.
Study of the influence of magnetic properties of amorphic alloys on the electromagnetic field of current transformers with a short-closed circuit
Authors: Klimenko Xenia A 
Published: May 2020

Abstract
The optimal functioning of the electric power industry can be ensured only if the important problem is successfully resolved by reliable measurement of electrical quantities, such as voltage, current, and power. In industry, a current transformer is often used as a current meter, which makes it possible to obtain an AC current measurement result with high accuracy. Structurally, the current transformer has a significant drawback, which is that the opening of the secondary measuring winding leads to an emergency. To solve this problem, you can apply the improved design of the current transformer squirrel-cage current transformer (in the form of a cylinder or ring). This article presents the results of two-dimensional modeling of the electromagnetic field of current transformers with a short-circuited coil, with cores made of different grades of amorphous iron in the ELCUT software package. In addition, the results of experimental studies of the improved design of the current transformer are presented. An analysis of the results allows us to conclude that the use of a core made of amorphous iron with a higher magnetic permeability will lead to economic benefits and make the measurement process more energy efficient.

The economic dimension of globalization
Authors: Steger Manfred B. 
Published: May 2020

Abstract
Economic globalization refers to the intensification and stretching of economic connections across the globe. ‘The economic dimension of globalization’ gives a brief history of the emergence of the global economic order. Towards the end of the Second World War, the Bretton Woods Conference laid the foundations for institutions such as the International Monetary Fund, the World Bank, and World Trade Organization. In the 1980s, rising neoliberalism led to the deregulation of financial transactions. Significant developments include the internationalization of trade, the increasing power of transnational corporations, and the enhanced role of international economic institutions. We have recently experienced setbacks like the 2007–10 recession and the slowdown of the Chinese economy.
The political dimension of globalization
Authors: Steger Manfred B. 
Published: May 2020

Abstract
Political globalization refers to the intensification and expansion of political interrelations across the globe. ‘The political dimension of globalization’ raises political issues relating to state sovereignty and the question of whether the nation-state will survive globalization. Growing social, economic, and cultural interconnectedness has facilitated migration in large numbers and permeated borders. Contemporary globalization has put pressure on traditional forms of global governance by fostering the growth of supraterritorial social spaces and institutions that unsettle both familiar political arrangements and cultural traditions. The worldwide intensification of cultural interactions makes greater accommodation and tolerance possible, but it is just as likely to increase political resistance and opposition.

Published: May 2020

AbstractBackgroundAging of upper arm skin, induced by intrinsic and extrinsic factors, often results in a loss of contour, elasticity, and firmness, and an increase in laxity, crepiness, roughness, and photodamage. A topical body firming moisturizer (TBFM) was developed to target all aspects of skin aging.ObjectivesThe aim of this study was to evaluate the efficacy and tolerability of the TBFM for upper arm firming and rejuvenation.MethodsForty female subjects, 40 to 60 years old, Fitzpatrick skin type II to V, with mild to moderate laxity, crepiness, and photodamage on the upper arms, were recruited into the study, 10 of whom were selected for biopsy analysis. Subjects were randomly allocated to apply the TBFM and placebo moisturizer on the assigned arms twice daily for 12 weeks. At each visit, efficacy and tolerability evaluation, self-assessment, and standardized clinical photography were performed. Ultrasound measurements were performed at baseline, week 8 and week 12.ResultsEfficacy evaluation by a clinical grader and bioinstrumentation analysis showed the TBFM improved all skin parameters of the aged upper arm while outperforming the placebo moisturizer after 12 weeks. Clinical photography showed the test product toned and firmed the skin. The TBFM was well tolerated and well perceived by the subjects. Ultrasound images indicated an improvement in skin density and skin structure at week 12.ConclusionsThis clinical trial indicates that the TBFM was well tolerated and was effective in improving crepey, lax, and photodamaged skin of the upper arms after 12 weeks of treatment twice daily.Level of Evidence: 2

Published: May 2020

ABSTRACTCyclic dimeric adenosine 3′,5′-monophosphate (c-di-AMP) is an emerging second messenger in bacteria and archaea that is synthesized from two molecules of ATP by diadenylate cyclases and degraded to pApA or two AMP molecules by c-di-AMP-specific phosphodiesterases. Through binding to specific protein- and riboswitch-type receptors, c-di-AMP regulates a wide variety of prokaryotic physiological functions, including maintaining the osmotic pressure, balancing central metabolism, monitoring DNA damage and controlling biofilm formation and sporulation. It mediates bacterial adaptation to a variety of environmental parameters and can also induce an immune response in host animal cells. In this review, we discuss the phylogenetic distribution of c-di-AMP-related enzymes and receptors and provide some insights into the various aspects of c-di-AMP signaling pathways based on more than a decade of research. We emphasize the key role of c-di-AMP in maintaining bacterial osmotic balance, especially in Gram-positive bacteria. In addition, we discuss the future direction and trends of c-di-AMP regulatory network, such as the likely existence of potential c-di-AMP transporter(s), the possibility of crosstalk between c-di-AMP signaling with other regulatory systems, and the effects of c-di-AMP compartmentalization. This review aims to cover the broad spectrum of research on the regulatory functions of c-di-AMP and c-di-AMP signaling pathways.

AbstractBackgroundPeople living with HIV are at an increased risk of diabetes mellitus due to HIV infection and exposure to antiretroviral therapy (ART). Despite this, integrated diabetes screening has not been implemented commonly in African HIV clinics. Our objective was to explore the feasibility of integrating diabetes screening into existing routine HIV viral load (VL) monitoring and to determine a group of HIV patients that benefit from a targeted screening for diabetes.MethodsA mixed methods study was conducted from January to July 2018 among patients on ART aged≥18 y and healthcare workers at an urban HIV clinic in Zomba Central Hospital, Malawi. Patients who were due for routine VL monitoring underwent a finger-prick for simultaneous point-of-care glucose measurement and dried blood spot sampling for a VL test. Diabetes was diagnosed according to WHO criteria. We collected demographic and medical history information using an interviewer-administered questionnaire and electronic medical records. We conducted focus group discussions among healthcare workers about their experience and perceptions regarding the integrated diabetes screening program.ResultsOf patients undergoing routine VL monitoring, 1316 of 1385 (95%) had simultaneous screening for diabetes during the study period. The median age was 44 y (IQR: 38–53); 61% were female; 28% overweight or obese; and median ART duration was 83 mo (IQR: 48–115). At baseline, median CD4 count was 199 cells/mm3 (IQR: 102–277) and 50% were in WHO clinical stages I or II; 45% were previously exposed to stavudine and 88% were virologically suppressed (&lt;1000 copies/mL). Diabetes prevalence was 31/1316 (2.4%). Diabetes diagnosis was associated with age ≥40 y (adjusted OR [aOR] 7.44; 95% CI: 1.74 to 31.80), being overweight and/or obese (aOR 2.46; 95% CI: 1.13 to 5.38) and being on a protease inhibitor-based ART regimen (aOR 5.78; 95% CI: 2.30 to 14.50). Healthcare workers appreciated integrated diabetes screening but also reported challenges including increased waiting time, additional workload and inadequate communication of results to patients.ConclusionsIntegrating diabetes screening with routine VL monitoring (every 2 y) seems feasible and was valued by healthcare workers. The additional cost of adding diabetes screening into VL clinics requires further study and could benefit from a targeted approach prioritizing patients aged ≥40 y, being overweight/obese and on protease inhibitor-based regimens.
The Collateralizability Premium
Authors: Ai Hengjie , Li Jun E , Li Kai , Schlag Christian 
Published: May 2020

Abstract
A common prediction of macroeconomic models of credit market frictions is that the tightness of financial constraints is countercyclical. Theory suggests a negative collateralizability premium; that is, capital that can be used as collateral to relax financial constraints insures against aggregate shocks and commands a lower risk compensation compared with noncollateralizable assets. We show that a long-short portfolio constructed using a novel measure of asset collateralizability generates an average excess return of around 8% per year. We develop a general equilibrium model with heterogeneous firms and financial constraints to quantitatively account for the collateralizability premium.
The Brain and Causality: How the Brain Becomes an Individual-Level Cause of Illness
Authors: Halpin Michael 
Published: May 2020

Abstract
How do individual-level explanations become applied to social issues? Neurobiology – the study of the connections between behavior and the cells and structures of the brain – receives substantial public funding and influences social institutions, policy debates, and core aspects of human experience. With respect to mental health, neurobiology has ramifications for the way disorders are defined, diagnosed, and treated, along with how public funding for mental illness is allocated. This article addresses how neurobiologists establish the brain as a cause of mental illness. I analyze 17 months of ethnographic observation at a well-regarded neurobiological research laboratory, as well as observations at professional meetings, to detail three strategies: Linking the Brain to Mental Illness, Explaining Mental Illness with the Brain, and Asserting the Causal Importance of the Brain. These strategies first connect the brain to mental illness, and subsequently establish the causal primacy of the brain relative to alternative explanations (e.g., poverty). I connect findings to medical sociological theories, biological reduction, and emerging national health policies.
