Published: September 2021

Abstract
Lithium-ion capacitor (LICs) is expected to replace the traditional double-layer capacitor and lithium-ion battery as a new energy storage device. However, the slow de/intercalation of Li+ in battery-type electrodes (anode) limits the power density of lithium-ion capacitors (LICs). In this work, a high specific surface area porous carbon skeleton (Z-T-PC) is synthesized derived from MOF (Zn-TFBDC). Benefit from the large specific surface area and 3D conductive skeleton, the Z-T-PC shows that the sample has a high specific capacity and stable cycling performance as the LIC anode. The assembled asymmetric LICs exhibit high power density and energy density with Z-T-PC anode. The work provides new thinking for the application of the novel anode material of LICs.

Abstract
Epitaxial layers of semiconductor solid solutions of molecular substitution (GaAs)1-z(ZnSe)z (0 < z < 0.80) with a smoothly (but not monotonously) varying composition were obtained from the liquid phase on monocrystal GaAs (100) substrates. The solubility of gallium arsenide and zinc selenide in tin and the phase diagrams of binary systems Ga-Sn, As-Sn, Zn-Sn and Sn-Se indicate that binary compounds in the tin solvent at temperatures of 650–750°C, below the melting point of the corresponding materials, are not in the form of individual atoms of gallium, arsenic, zinc and selenium, but in the form of molecules of gallium arsenide and zinc selenide. Moreover, in the temperature range 650-750°C, the solubility of GaAs in tin varies from ∼ 2.6 to ∼ 5.5 mol%, and ZnSe - from ∼ 0.2 to ∼ 0.35 mol%, the solubility of gallium and zinc is unlimited, and the solubility of arsenic is more than 70 at. %, selenium - more than 5 at.%. It is shown that due to the difference in the valence of gallium and arsenic atoms, the forces of chemical bonds between neighboring Ga and As atoms located in the tetrahedral lattice are not the same. In the tetrahedral lattice, each Ga atom forms 4 bonds with four neighboring As atoms, three of which are formed by the sharing of electrons of neighboring Ga and As atoms, and the fourth one only due to the two valence electrons of the As atom. Apparently, the ionic fraction of the fourth chemical bond is stronger than the other three.

Abstract
The rate of industrial development depends not only on the demand for products that are outdated in terms of quality, but also on the possibility of updating the quality indicators of the raw material mass, matching the demand dynamics of the raw materials quality with the indicators corresponding to the future tasks. The transition of the world economy and energy to a low-carbon development trajectory reduces the demand for Russian coal, and therefore the near future of the coal industry is associated with fundamental changes in the requirements for the quality and variety of marketable products. There is an urgent need for technological renewal in coal enrichment, restoration and further development of coal chemistry. The paper highlights the key problems and trends in the field of deep coal enrichment, reveals the methods used in the processing plants of Kuzbass. The proposed technology of deep mineral processing “Carbon-99”, which received the support of the Skolkovo Innovation Center in 2021, is described. The Carbon-99 technology is a synthesis of technological solutions groups, which variety depends on the properties of the mineral groups included in a particular coal material: enrichment of rock mass cl. 2-200 mm, magnetic separation cl. 0-2 mm, enrichment of sludge masses-centrifugation cl. 0-0. 05 mm. It is shown that the proposed complex technology of deep coal enrichment will reduce the ash content in the concentrates of brown, coking and anthracite coals to 1-9%, and reduce the sulfur content by 30-70%. Reduction of moisture content in the coal mass, including dispersed materials. Also, to obtain concentrates of mineral groups extracted from the coal mass, without chemical reagents.

Published: September 2021

Abstract
Our research was aimed at modeling a symmetrical wrapping and stable control of the processes of shaping by wrapping a sheet blank along a wrapping punch having a double curvature surface and placed on the table of a virtual stretch-tightening press. The main task of modeling was to determine the deformed state with a uniform change in thickness in different regions of the sheet blank without folds and breaks, but without the influence of the rheological behavior of the deformable aluminum alloy. Here, the LS-DYNA software package is used with the use of an explicit or implicit solver for nonlinear problems of solid mechanics, characteristic of nonequilibrium transitions of the initial dissipative phase due to viscosity and heat transfer. Now it is possible to predict defect formation from a practical point of view, using the forming limit diagram (FLD), which makes it possible with sufficient accuracy to determine the degree of deformation of a given sheet material, at which any defects do not occur. The presented results of the study revealed the features of the influence of the rheological behavior of a wrought sheet aluminum alloy on the limits of the shaping process by a wrap.

Published: September 2021

Abstract
The magnetic material of Fe-Nd-B alloys is widely used in science and technology due to the unique physical and chemical properties of borides based on it. The functional properties of the material significantly depend on the structural-phase state in the alloy. The transition on the Melt Quenching technology (MQ) for its production required additional theoretical and experimental studies of the regularities of the formation and stability of the structural-phase state in multicomponent REM-containing alloys under conditions of nonequilibrium crystallization and solidification of a highly supercooled melt. The implementation of the industrial MQ technology by the method of Gas Atomization (GA) of medium pressure imposes additional significant requirements for such studies. The paper comprehensively studies and summarizes the available results on the relationship between the conditions for obtaining powder materials of Fe-Nd-B alloys by the MQ GA method and the functional properties of materials based on them. It is proved that the anisotropy features of their magnetic properties are related to the existing inhomogeneities in the distribution and morphology of Fe14Nd2B phase grains in MQ GA powder materials. A crystal-chemical explanation of the occurrence of the identified features is proposed and the possibility of their practical application is shown.

Abstract
One of the most common damage to the structural elements of vessels and apparatus of hydrocarbon processing plants is mechanical damage, which mainly occurs during repair and installation operations. One of the prerequisites for the occurrence of this type of defects is the use of a locksmith tool and other devices, tools and devices, upon contact of which with the surface of the elements to be repaired and mounted, risks, scratches, balls, nicks and other damage are formed. The vast majority in terms of the degree of occurrence on the surface of structural elements of all defects of a mechanical nature occupy scratches. There is practically no technical device operating in a hazardous production facility and does not have at least one of the elements of this type on the external surface. With respect to the surface on which the scratches are arranged, these defects can be both small geometrical dimensions and sufficiently extended. Such defects generally do not limit the life cycle of the object, but can have a significant effect on the redistribution of the stress-strain state in the element. The redistribution of the stress-strain state can serve as an initial stage for the generation of potential fracture sites from the concentration of increased stresses in these zones. Also, not only the presence of a scratch, but also the length, as well as the nature of the location on the surface of the element, can affect the stressed-deformed state of the element. Therefore, the actual work is a study of the change in the stress-deformed state of the flat manhole cover with a scratch, the arrangement of which on the surface has various options. In this work, the stress-strain state of the flat manhole cover is simulated depending on the change in the angle of inclination and the location of the scratch on it relative to the central zone.

Thermoelastic non-stationary fields in a rigidly fixed plate
Authors: Kusaeva Zh M 
Published: September 2021

Abstract
In this article, a new closed solution of the axisymmetric dynamic problem of the theory of thermoelasticity is constructed for a rigidly fixed circular isotropic plate in the case of temperature changes on its face surfaces. The mathematical formulation of the problem includes linear equations of motion and thermoelasticity in the spatial formulation with respect to the components of the displacement vector, as well as the function of temperature change. The study of non-self-adjoint equations is carried out in an unrelated statement. Initially, we consider the initial boundary value problem of thermoelasticity without taking into account the deformation of the plate, and at the next stage, we study the problem of elasticity theory under the action of a given (defined) temperature change function. To solve the problems, we use a mathematical apparatus for separating variables in the form of finite integral transformations: Fourier, Hankel, and generalized integral transformation (CIP). In this case, at each stage of the study, the procedure is performed to bring the boundary conditions to the form that allows you to apply the appropriate transformation.

Abstract

Background
Medication nonadherence of patients with chronic conditions is a complex phenomenon contributing to increased economic burden and decreased quality of life. Intervention development relies on accurately assessing adherence but no “gold standard” method currently exists.

Purpose
The present scoping review aimed to: (a) review and describe current methods of assessing medication adherence (MA) in patients with chronic conditions with the highest nonadherence rates (asthma, cancer, diabetes, epilepsy, HIV/AIDS, hypertension), (b) outline and compare the evidence on the quality indicators between assessment methods (e.g., sensitivity), and (c) provide evidence-based recommendations.

Methods
PubMed, PsycINFO and Scopus databases were screened, resulting in 62,592 studies of which 71 met criteria and were included.

Results
Twenty-seven self-report and 10 nonself-report measures were identified. The Medication Adherence Report Scale (MARS-5) was found to be the most accurate self-report, whereas electronic monitoring devices such as Medication Event Monitoring System (MEMS) corresponded to the most accurate nonself-report. Higher MA rates were reported when assessed using self-reports compared to nonself-reports, except from pill counts.

Conclusions
Professionals are advised to use a combination of self-report (like MARS-5) and nonself-report measures (like MEMS) as these were found to be the most accurate and reliable measures. This is the first review examining self and nonself-report methods for MA, across chronic conditions with the highest nonadherence rates and provides evidence-based recommendations. It highlights that MA assessment methods are understudied in certain conditions, like epilepsy. Before selecting a MA measure, professionals are advised to inspect its quality indicators. Feasibility of measures should be explored in future studies as there is presently a lack of evidence.

Abstract
The establishment of endometrial receptivity is a prerequisite for successful pregnancy. Women with adenomyosis possess a lower chance of clinical pregnancy after assisted reproductive technology, which is partially due to impaired endometrial receptivity. The establishment of endometrial receptivity requires the participation of multiple processes, and proper endometrial epithelial cell (EEC) proliferation is indispensable. Monoamine oxidase A (MAOA) is a key molecule that regulates neurotransmitter metabolism in the nervous system. In the present study, we demonstrated a novel role for MAOA in the establishment of endometrial receptivity in women with adenomyosis and in an adenomyotic mouse model. Attenuated MAOA impairs endometrial receptivity by promoting inappropriate proliferation of EECs via the downregulation of FOXO1 during the window of implantation. These results revealed that MAOA plays a vital role in endometrial receptivity in female reproduction.

AbstractBackgroundConstrictive pericarditis (CP) is one of the most serious sequelae of tuberculous pericarditis, which is characterized by heart constriction secondary to intense pericardial inflammation and thickening. Several invasive and non-invasive diagnostic modalities are crucial to address the challenges of confirming the diagnosis of CP and to expedite timely intervention.Case summaryThis study reports the case of a Bahraini male with tuberculous lymphadenitis diagnosed with CP as a result of various evaluations. The patient underwent urgent total pericardiectomy and showed remarkable recovery with complete resolution of heart failure symptoms.DiscussionThis case demonstrates the paramount importance of early diagnosis and treatment for patients with CP. In this unique case, the acoustic windows on echocardiography were suboptimal because of pericardial thickening. Further, computed tomography did not show significant calcification of the thickened pericardium. A novel approach of assessing haemodynamics through the right antecubital vein and right radial artery facilitated the accurate diagnosis of CP with confidence. Thereafter, successful pericardiectomy revealed a markedly thickened and stiff pericardium with many abscesses and dense adhesions encasing the heart, and pericardial biopsy showed large caseating granulomas. This case exemplifies the difficulty in diagnosing CP and the favourable outcomes achieved with well-timed surgical intervention.

Abstract
Rumen epithelium plays an essential role in absorption, transport, and metabolism of short-chain fatty acids, the main products of rumen fermentation, and in preventing microbes and other potentially harmful rumen contents from entering the systemic circulation. The objective of this study was to generate an immortal rumen epithelial cell line that can be used as a convenient model of rumen epithelial cells in vitro. We isolated primary rumen epithelial cells from a steer through trypsin digestion and transduced them with lentiviruses expressing the Simian Virus (SV) 40 T antigen. We cloned the transduced cells by limiting dilution. Western blotting analysis confirmed the expression of the SV40 T antigen in two single-cell clones. Cells from one clone, named bovine rumen epithelial clone 1 (BREC1), displayed a flat and squamous morphology in culture. RNA sequencing revealed that BREC1 cells expressed many markers of epithelial cells, including keratins, the epidermal growth factor receptor, and the short-chain fatty acid transporters monocarboxylic acid transporter (MCT) 1 (MCT-1) and MCT-4. RNA sequencing revealed that BREC1 cells expressed key enzymes such as 3-hydroxymethyl-3-methylglutaryl-CoA lyase and 3-hydroxy-3-methylglutaryl-CoA synthase 1 involved in ketogenesis, a unique function of rumen epithelial cells. RNA sequencing also revealed the expression of genes encoding tight junctions, desmosomes, anchoring junctions, and polarized plasma membranes, structures typical of epithelial cells, in BREC1 cells. Cell proliferation assays indicated that BREC1 cells were similar to primary rumen epithelial cells in response to insulin-like growth factor 1, insulin, and butyrate. In conclusion, BREC1 is not only a convenient but an appropriate model for studying the factors and mechanisms that control proliferation, apoptosis, differentiation, nutrient transport, metabolism, and barrier function in rumen epithelium.

Published: September 2021

AbstractPigs with complete resistance to porcine reproductive and respiratory syndrome (PRRS) virus (PRRSV) have been produced by genetically knocking out the CD163 gene that encodes a receptor of the PRRSV for entry into macrophages. The objectives of this study were to evaluate associations of naturally occurring single nucleotide polymorphisms (SNPs) in the CD163 gene and in three other candidate genes (CD169, RGS16, and TRAF1) with host response to PRRSV-only infection and to PRRS vaccination and PRRSV/porcine circovirus 2b (PCV2b) coinfection. SNPs in the CD163 gene were not included on SNP genotyping panels that were used for previous genome-wide association analyses of these data. An additional objective was to identify the potential genetic interaction of variants at these four candidate genes with a mutation in the GBP5 gene that was previously identified to be associated with host response to PRRSV infection. Finally, the association of SNPs with expression level of the nearby gene was tested. Several SNPs in the CD163, CD169, and RGS16 genes were significantly associated with host response under PRRSV-only and/or PRRSV/PCV2b coinfection. The effects of all SNPs that were significant in the PRRSV-only infection trials depend on genetic background. The effects of some SNPs in the CD163, CD169, and RGS16 genes depend on genotype at the putative causative mutation in the GBP5 gene, which indicates a potential biological interaction of these genes with GBP5. In addition, genome-wide association results for the PRRSV-only infection trials revealed that SNPs located in the CDK5RAP2 or MEGF9 genes, near the TRAF1 gene, had suggestive effects on PRRS viral load, which indicates that these SNPs might contribute to PRRSV neuropathogenesis. In conclusion, natural genetic variants in the CD163, CD169, and RGS16 genes are associated with resistance to PRRSV and/or PCV2b infection and appear to interact with the resistance quantitative trait locus in the GBP5 gene. The identified SNPs can be used to select for increased natural resistance to PRRSV and/or PRRSV-PCV2b coinfection.
“But You’re Not at All like Bertha”: Contemporary (Black) Trans* Studies and Richard Wright’s “Man of All Work”
Authors: Foster Guy Mark 
Published: September 2021

AbstractThis essay mines the intersections among contemporary trans* studies, black feminism, and black studies to reexamine Richard Wright’s short story, ‘Man of All Work’ (1961), depicting a black heterosexual man’s efforts to save his home from foreclosure by dressing in his wife’s clothes to find work. Rather than engage these critical traditions in rigid identitarian terms, this essay uses such scholarship to examine how the author’s farcical attempts to dramatize the cultural feminization of black men yields complex theoretical insights as to the impact of anti-black racism on the lived experiences of black people. A key insight from black studies is the tendency of US white supremacy to collapse black gender difference into sameness, thereby excluding black men and women from sexual difference. Highlighting the fungibility of black gender, this essay works these scholarly intersections to examine how the self-conscious exploitation of anti-black assumptions about the body creates the potential for unlikely intraracial solidarities to emerge.
