Published: July 2023

Agricultural crops are threatened by plethora of Plant diseases. Diseases can lead to 100% crop loss, and can destroy the economic production. Various groups of micro-organisms are known to cause epidemic, endemic, pandemic and sporadic diseases in plants. Plant viral diseases have significant economic consequences for the agricultural industry. They can reduce crop yields, lower the quality of harvested produce, and lead to crop losses. Some of them also gets transmitted by different insects and spread rapidly. Mainly the sucking insects like aphids, whiteflies, leafhoppers, thrips etc are majorly known vectors of plant diseases. Since decades, the vector borne transmission studies, protection techniques, dissemination studies were the core interest of the scientific community. In our current bibliometric research, we have aimed to identify the majorly contributed countries, the collaborative institutes, suggestive precautionary methods to analyse all vector borne plant diseases. The purpose of this study is to examine global research conducted between 1966 and 2023, with a focus on the use of different vector borne plant diseases, protection techniques, identification techniques for diagnostic assays studies. This analysis provides insights into the major publishing journals, institutions involved, leading journals, influential authors, most cited articles, and common keywords by retrieving data from the 'Dimensions' database and employing bibliometric visualization software.

Psoriasis is an immune mediated chronic inflammatory disease with an incidence rate ranging from 0.09–11.4% in the general population. Psoriasis has complex etiological factors, and its pathogenesis is still not fully understood, which poses challenges in clinical treatment. However, macrophages, acting as "sentinels" of innate immunity, have recently gained attention as a novel area of focus in immunological research on psoriasis. Recent research has found that macrophage plasticity play an important role in the initiation and maintenance of psoriasis, However, it remains underexplored how macrophage plasticity mediates the immune response to psoriasis and what the corresponding regulatory mechanism is. To investigate the involvement of macrophage polarization in the pathogenesis of psoriasis. In our study, we firstly obtained the skin gene expression dataset of both normal subjects and psoriasis patients through the GEO database, from which psoriasis patients showed a higher expression of M1 macrophage-related genes and a lower expression of M2 macrophage-related genes in skin lesions. Then, we established a mouse model of psoriasis-like dermatitis induced by Imiquimod (IMQ) and found that the macrophages in the lesions and spleen of IMQ-induced psoriasis mice were predominantly M1 macrophages. Then, we extracted primary peritoneal macrophages (PEM) from mice and induced their polarization into M1 macrophages and M2 macrophages in vitro. Intravenous infusion of M1 macrophages to IMQ-induced psoriasis-like dermatitis mice resulted in the exacerbation of psoriasis-like dermatitis in these mice. Besides, macrophage polarization was found to affect the differentiation of T cells using the RNA-seq technology. We also noticed that M1 macrophages promoted the CD4+ T cell proliferation and T helper cell 17 (Th17) differentiation and M1 macrophages could directly activate the inflammatory response of JB6 (mouse epidermal cells) independent of T cells. Taken together, this study derives new findings that M1 macrophages regulate the proliferation and differentiation of T cells and directly activate the expression of inflammatory cytokines of keratinocytes (KC) independent of T cells to participate in the occurrence and development of psoriasis. These findings provide new insights into the pathogenesis of psoriasis and identify inhibiting M1 polarization as a promising target for the treatment of this condition.

Since 2010, several strains of Duck Tembusu Virus (DTMUV) have been isolated from China. In autumn 2021, high mortality was observed in southwestern Guizhou Province, China, and a DTMUV strain named GZSS2022 was successfully isolated. After inoculation with SPF chicken embryos of 10 days age, the embryos died 3-5 days after inoculation, and RT-PCR could still detect DTMUV positive after collecting the allantoic fluid of dead chicken embryos and transmitting it for 4 generations. In addition, the GZSS2022 strain was able to replicate in BHK-21 cells and induce cytopathic effects (CPE), and the virus particles were observed in the cytoplasm by transmission electron microscopy. In animal experiments, GZSS2022 strain can replicate stably and pathological examination results showed that the brain of infected ducks was congested and vascular sheath formed around the blood vessels; Liver lymphocyte infiltration, necrosis, liver bleeding. The E gene of this strain was sequenced by PCR and its homology and genetic evolution were analyzed. It was found that the homology of GZSS2022 with the Beijing duck reference strain (MT108699.1) was the highest 99.39%, and the homology of GZSS2022 with the early isolated reference strain (FX2010) was 96.88%. The GZSS2020 strain was located in the same subbranch as the reference strain from Beijing duck in China. The results of this study indicate that a novel highly virulent Tambusu virus has appeared for the first time in Guizhou Province, China, and further lay the foundation for the study of the pathogenicity and host range of this novel Tambusu virus.

Published: July 2023

Path planning for a swarm of drones is primarily concerned with avoiding collision among the drones and environmental obstacles while determining the most efficient flight path to the region of interest. This paper proposes an efficient methodology for drone swarm path planning problems in 3D environments. An improved population based meta-heuristic algorithm, Sine Cosine Algorithm (SCA), has been proposed to solve this problem. As part of the improvements, the population of SCA is initialized using a chaotic map, and a non-linearly decreasing step size is used to balance the local and global search. In addition, a convergence factor is employed to increase the convergence rate of the original SCA. The performance of the proposed improved SCA (iSCA) is tested over the drone swarm path planning problem, and the results are compared with those of the original SCA, and other state-of-the-art meta-heuristic algorithms. The experimental results show that the drone swarm 3D path planning problem can be efficiently handled with the proposed improved SCA

Background: Vector control using insecticides is a key prevention strategy against malaria. Unfortunately, insecticide resistance in mosquitoes threatens all progress in malaria control. In the perspective of managing this resistance, new insecticide formulations are being urged to improve the effectiveness of vector control tools.
Methods: The efficacy and residual activity of Pirikool® 300 CS was evaluated in comparison with Actellic® 300 CS in experimental huts at the Tiassalé experimental station on three substrates including cement, wood and mud. The mortality, blood-feeding inhibition, exiting behaviour and deterrency of free-flying wild mosquitoes was evaluated. Cone Bioassay tests with susceptible and resistant mosquito strains were conducted in the huts to determine residual efficacy.
Results: A total of 20505 mosquitoes of which 10979 (53%) wild female Anopheles gambiae were collected for 112 nights. Residual efficacy obtained from monthly cone bioassay was higher than 80% with the susceptible, laboratory-maintained An. gambiae Kisumu strain from the first to the tenth study period on all three types of treated substrate for both Actellic® 300CS and Pirikool® 300CS. This residual efficacy on the wild Tiassalé strain was over 80% until the 4th month of study on Pirikool® 300CS S treated substrates.
Overall 24-hour mortalities of wild free-flying An. gambiae s.l. which entered in the experimental huts over the 8-months trial on Pirikool® 300CS treatment was 50.5%, 75.9% and 52.7% respectively on cement wall, wood wall and mud wall. The positive reference product Actellic® 300CS treatment induced mortalities of 42.0%, 51.8% and 41.8% on cement wall, wood wall and mud wall.
Conclusion: Pirikool® 300CS has performed really well against resistant strains of An. gambiae s.l. using indoor residual spraying method in experimental huts. It could be an alternative product for indoor residual spraying in response to the vectors' resistance to insecticides.

The article presents the possibility of increasing the water-resistance of gypsum binders obtained based on synthetic gypsum by introducing additives derived from industrial wastes. Regularities were obtained for the influence of the type and amount of additives on the water-gypsum ratio, strength indicators, and water resistance of high-strength gypsum binder. The introduction of a single-component additive to improve water resistance does not have a significant effect. Complex additives based on Portland cement, granulated blast-furnace slag, electric steel-smelting slag, expanded clay dust and granite screenings of various fractions have been developed that make the maximum contribution to improving the water resistance of a high-strength gypsum binder based on synthetic calcium sulfate dihydrate, which made it possible to increase the water-resistance coefficient from 0.39 to 0.82.

Authors: Peeters Noëlle J.M.C. Vrancken , Til Janine A. Van , Huberts Anouk S. , Siesling Sabine , Husson Olga , Koppert Linetta B.
Published: July 2023

Objectives
The EQ-5D-5L and the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core-30 (EORTC QLQ-C30) are commonly used Patient-Reported Outcome Measures (PROMs) in breast cancer patients. For utilizing PROMs in research and clinical settings, internal responsiveness is key. Therefore, the aim of this study is to evaluate and compare the internal responsiveness of the EQ-5D-5L and EORTC QLQ-C30 among breast cancer patients during the first-year post-surgery.
Methods
Effect sizes (ES) and standardized response means (SRM) were calculated for the EQ-5D-5L and EORTC QLQ-C30 between baseline and 6 months post-surgery (delta 1) and between baseline and 12 months post-surgery (delta 2). Delta 1 and 2 of the EQ-5D-5L index and EORTC QLQ-C30 Global Quality of Life scale were compared to the corresponding minimal important clinical difference (MICD).
Results
In total 333 breast cancer patients treated at the Erasmus MC, who completed the EQ-5D-5L and the EORTC QLQ-C30 at baseline, 6- and 12-months post-surgery were included. The internal responsiveness of both the EQ-5D-5L and the EORTC QLQ-C30 was poor (< 0.05) and larger for delta 1 compared to delta 2. The internal responsiveness of the EQ-5D-5L index was larger than the EORTC QLQ-C30 Global Quality of Life scale and EORTC QLQ-C30 summary score.
Conclusions
Both the EQ-5D-5L and EORTC QLQ-C30 demonstrate poor internal responsiveness in breast cancer patients at 6- and 12-months post-surgery. Other approaches such as administering PROMs at different intervals or utilizing breast cancer specific PROMs may be considered to improve research and patient-centered healthcare.

Published: July 2023

One of the deadliest pandemics of the 21st century is being driven by SARS-CoV-2, a significant betacoronavirus, causing severe to moderate respiratory tract infections and represents a major public health threat than other human coronaviruses like severe acute respiratory syndrome (SARS) CoV and Middle East respiratory syndrome (MERS), which has been ravaging the world’s health, social life, and the economy. In response to the sixth wave of SARS-CoV-2, we aim to develop novel innovative viral replication inhibitor therapeutics. We achieved highly specific siRNAs by optimizing RNAi efficacy and reducing potential side effects and considering various factors such as target RNA variations, thermodynamics, accessibility of the siRNA, and off-target effects. Out of 258 siRNAs targeting conserved regions, four siRNAs (siRNA1, siRNA2, siRNA3, siRNA4) were chosen based on their predicted potency and high specificity that target critical highly conserved areas (NSP8, NSP12, and NSP14) in the viral genomes of SARS, MERS, and SARS-CoV2 with no predicted human genome off-targets. We assess the effectiveness of the four siRNAs on SARS-CoV2 strain hCoV-19/Egypt/NRC-03/2020. In VeroE6 cells, the selected siRNAs at a concentration 100nM had no cellular toxicity. siRNA2 significantly reduced viral replication with a knockdown percentage of 98% after 24 hr post-infection. In addition, siRNA4 had a statistical significance and knockdown percentage, in S gene and ORF1b gene, of 94% in viral replication. SiRNA2 and siRNA4 could be considered as potential siRNA therapy for SARS-CoV-2 infection.
AMDCENR: Attention Mechanism and Deep Curve Estimation under Noise Reduction Network for low-light image enhancement
Authors: Tian Bowen , Ding Jianwei , Zhang Qi , Deng Qiyao
Published: July 2023

Photographs captured under low-light conditions are often plagued with issues such as low brightness, poor contrast and noise, making them unsuitable for various image processing applications. To address these challenges, previous low-illumination image enhancement methods, based on the zero-reference depth network model (Zero-DCE), have attempted to approximate pixel-wise and higher-order curves by iteratively applying themselves. However, these methods have not considered the inevitable presence of noise in low-light images, which can have a significant impact on the quality of the enhanced images. To address this limitation, we present an approach, named Attention Mechanism and Deep Curve Estimation under Noise Reduction Network (AMDCENR-net), for low-light image enhancement. Our approach utilizes a regularization model and elemental subtraction to iteratively refine the light map and achieve image denoising. To improve the quality of low-light images and address the issue of missing information, we augment our approach by incorporating channel attention and spatial attention. Channel attention aims to enhance the informative channels in the image while suppressing the unimportant ones. Spatial attention, on the other hand, focuses on highlighting the salient regions of the image. Extensive experiments demonstrate the advantages of our method over state-of-the-art methods qualitatively and quantitatively.

In this research paper, we have standardized a rapid method for estimation of chlorpyrifos residues in feed samples using Gas Chromatograph- Micro Electron Capture Detector(GC-µECD). The extraction method used for this study was QuEChERS viz. quick, easy, cheap, effective, rugged and safe. Validation was done by performing the following parameters; Linearity, Limit of detection (LOD), Limit of quantification (LOQ), Matrix effect and Recovery percentage. A regression equation with regression coefficient (r2) of 0.9913 was obtained indicating excellent linearity. LOD and LOQ of the method were obtained as 0.1 mg/L and 0.4 mg/L respectively. Recovery percentage of the spiked concentration 0.1 ppm was obtained as 85.7% and for 0.5 ppm it was 77.7%. We have analyzed in different feedstuffs (representing green fodder, dry fodder and concentrates) collected from six different districts (Guntur and East Godavari (Andhra Pradesh), Warangal (Telangana state) and Dakshina Kannada, Raichur and Gulbarga (Karnataka state)). From a total of 565 samples collected, 37 samples were positive for chlorpyrifos indicating a positivity rate of 6.55%. Among the positive samples except one oil meal sample, all the samples are under maximum permissible limits (MPL) suggested by codex alimentarius for animal feeds.

Published: July 2023

The application of wind tunnel for visualizing flow over any bluff or streamline body plays an indispensable role in concepting various aerodynamical phenomenon such as formation of vortices, generating lift and drag, calculation of velocity vector and pressure profiles etc. Flow visualization through smoke and laser optics in a subsonic wind tunnel to capture vortex formation over airfoils, cylindrical and conical bodies is the experimental approach which has been studied and manifested elaborately in the article. Using smoke as a seeding material, the flow of the same is allowed to pass over the model which is illuminated via a double pulse laser beam to visualize the formation of vortex and capture the same for future references. The experimentation of the above models is carried out in a Honeycomb subsonic wind tunnel in the Aerodynamics Lab of Aerospace Engineering in the university. The article will cover Computational Fluid Dynamics (CFD) performed on ANSYS for the particular NACA series, Cross correlation PIV for plotting velocity vector for the captured images of the seed particles and the respective images of the entire experimental set-up. The images captured during this experiment can be later used by the aerodynamicists for optimizing aerodynamic efficiency of the experimented models depending on the vortex formation and flow pattern. The images can also be used for advance calculations required in Particle Image Velocimetry (PIV) for calculating velocity of every speed particle.
The Complete Genome Sequence of Clade B, Wheat Streak
Mosaic Virus Isolate from Turkey
Authors: LBAGI Havva , Masonbrink Rick E , Miller W Allen
Published: July 2023

Wheat streak mosaic virus is one of the most widespread viruses in cereal crops, causing severe losses, dramatically affecting worldwide wheat production. Currently, four distinct clades of WSMV have been grouped and named: A (Mexico), B (Europe, Asia, Russia), C (Iran), and D (United States, Argentina, Brazil, Australia, Canada, Turkey). Each of these groups is based on genome-wide variability, emphasizing the CP. Previously reported Turkish wheat isolates of WSMV clustered within both clades D and B. However, the placement of the Turkish WMSV into clade B is only based on a partial genome sequence. Here, we used high throughput sequencing to assemble the complete genome sequence of WSMV type B isolate collected from wheat found in the European part of Turkey. Excluding the poly(A) tail, the genome of isolate S34Edirne (Genbank no. MZ405098) consists of 9,360 nucleotides and contains a single large open reading frame encoding a polyprotein of 3,033 amino acids. The characteristic lack of a GAG (Gly2761) codon within the CP of the polyprotein is typical for the clade B, WSMV-ΔE isolates, which are widely found throughout the European continent. However, two American isolates were recently placed in this group. Sequence comparisons revealed that WSMV Turkish wheat isolate is the most closely related to Czech isolate, with highly similar nucleotide and amino acid identities at 98.83-99.13%, respectively. The result of this study indicates that the WSMV full-length genome of S34Edirne isolate should be placed into clade B of the European WSMV-ΔE isolates.

Authors: Shandhi Shabiba Parvin
Published: July 2023

Oryza sativa bran was analyzed for its composition. The oil was extracted from the bran by Soxhlet extraction method. Chemical properties of extracted oil was studied in this research work. Rice bran of Kurigram contains a mixture of substances including oils, proteins, carbohydrates, fatty acids, minerals. moisture & ashes. The bran was collected from Kurigram. The bran was rich in carbohydrates and proteins. The important minerals were found like Fe, Zn, Ca, Mg, K, Na etc. Saponification value, iodine value are some important parameters usually considered in the evaluation of oil quality. Higher saponification (110.13 mg KOH/g) value of the oil indicated that it could be used as raw materials in good quality soap. It was determined by refluxing the oil with alcoholic KOH solution followed by titration with standard acid. Low iodine (46.25 I2/100g) value of the oil indicated that it could be used as cooking purpose and the oil was stable and consisting of poly unsaturated fatty acids mainly oleic and linoleic acid. It was determined by dissolving the bran oil in CCl4 solution with addition of Henus solution followed by titration with standard hypo solution. From fatty acid analysis it was found that the oil was high content of fatty acids such as oleic acid, linoleic acid, palmitic acid, stearic acid etc. These acids have high biological importance for human body.

Multistress effects lead to unpredicted consequences in aquatic ecotoxicology and are extremely concerning. The goal of this study was to trace how specific effects of the antibiotic salynomycin (Sal) and microplastics (MP) on the bivalve molluscs are manifested in the combined environmentally relevant exposures. Unio tumidus specimens were treated with Sal (0.6 µg L− 1), MPs (1 mg L− 1, 2 µm size), and both at 18°C (Mix) and 25°C (MixT) for 14 days. The redox stress and apoptotic enzyme responses and the balance of Zn/Cu in the digestive gland were analyzed. The shared signs of stress included a decrease in NAD+/NADH and Zn/Cu ratios and lysosomal integrity, and an increase in Zn-metallothioneins and cholinesterase levels. MP caused a decrease in the glutathione (GSH) concentration and redox state, total antioxidant capacity, and Zn levels. MP and Mix induced coordinated apoptotic/autophagy activities, increasing caspase-3 and cathepsin D (CtD) total and extralysosomal levels. Sal activated caspase-3 only and increased by five times Cu level in tissue. Due to the discriminant analysis, the cumulative effect was evident in the combined exposure at 18°C. However, under heating, the levels of NAD+, NADH, GSH, GSH/GSSG and metallothionein-related thiols were decreased, and coordination of the cytosolic and lysosomal death stimuli was distorted, confirming that heating and pollution could exert unexpected synergistic effects on aquatic life.

Published: July 2023

The paper discusses the success factors influencing product development design and product launch projects. The lives of people and businesses have been threatened and affected by the global COVID-19 pandemic for more than two years. Knowing these factors can help us make the right decisions and develop an effective project plan and matrix. Nowadays, project management is a very important part of work in companies of different sizes. Project management can be seen as applying innovation processes in an enterprise. The authors conducted quantitative and qualitative research on 544 companies in the Slovak Republic. The research focuses on aspects of project management and individual success factors. The data obtained by the questionnaire survey were processed by statistical methods, where the authors chose the nonparametric Kruskal-Wallis test as the basic method and the Wilcoxon two-tailed test for independent sample data sets. An essential variable in the sample of enterprises surveyed was, in particular, the sector of the economy in which the enterprise surveyed operates. Two key factors were considered when developing the product – employee education and the implication of social responsibility. The study’s uniqueness lies in surveying all types of enterprises, irrespective of their size, line of business, and financial turnover. The percentage distribution of the maximum use of CSR among the surveyed companies in each sector was most positive in the Logistics industry. Training and certification of employees are primarily one of the most important factors to ensure an increase in the success of those projects aimed at launching new products on the market; in the case of the surveyed sample, this is more than 40% of enterprises. Based on the sub-results, we can conclude that enterprises place more emphasis on new product development projects and the environmental concept of CSR. Still, the launch of new products or services is underestimated by the project management of enterprises. After more than eight years, the research has shown an increase in the importance of using social responsibility in management processes for new product development. A breakthrough finding is comparing the use of CSR in small businesses in Slovakia to global trends in which we perceive the dominance of multinational corporations. Enterprises are advised to focus specifically on new product launches and detailed planning.

Published: July 2023

The article summarises the arguments and counterarguments within the scientific debate on the issue of improving the system of combating money laundering. The research’s primary goal is to evaluate the system’s effectiveness in combating money laundering. The study of the issue of evaluating the system’s effectiveness for combating money laundering is carried out in the article in the following logical sequence: informative base forming; determination of terminal events as criteria for the system’s effectiveness for combating money laundering; survival tables construction, which provide for the probability of a court verdict on financial monitoring issues; evaluation of the system’s effectiveness of institutional changes in combating money laundering. Survival analysis methods or survival tables, the Kaplan-Meier method, were used to conduct the research. The developed scientific-methodical approach to evaluating the system’s effectiveness for combating money laundering was approved based on financial monitoring data in Ukraine; the study period was 2009-2022. The time intervals and established probabilities of avoiding punishment for the crime of money laundering were defined based on the analysis. The authors of the article empirically determined that with an increase in the time between the time of the commission of the crime and the time of the court’s conviction, the probability that the court will not be convicted decreases. If three years and seven months pass after the crime, the probability of a guilty verdict will be 50.9%. Based on the obtained calculations, the changes in the organisational and functional composition of the combating money laundering implemented in recent years could have improved the quality of combating money laundering. Further research should be directed to a detailed analysis of the structural elements in the institutional part of the system of combating money laundering to identify the weaknesses of each stage: financial monitoring, investigation and the judicial system.

Improving the technology of copper-zinc ore beneficiation of a Uralian-type pyrite deposit
Authors: Mamonov Sergei
Published: July 2023

Introduction and research objective. Copper-zinc ore of pyrite deposits of the Uralian type are refractory. Difficulties in beneficiation are due to their material composition: fine coarseness and emulsion impregnation of ore minerals in each other, a large amount of flotation-active pyrite, a high content of finely dispersed and submicroscopic gold in sulfides, etc. In the course of pyrite ore processing at dressing mills, 83–91% of copper and 10–45% of gold are extracted into copper concentrates, and 46–78% of zinc and 5–15% of gold are extracted into zinc concentrates. Increasing the process performance of pyrite deposit ore processing is a promising and urgent task. Methods of research included copper-zinc pyrite ore material composition study through quantitative chemical analysis, chemical phase analysis for the forms of copper, zinc, gold and silver compounds, and mineralogical analysis. Technological studies were carried out by flotation and gravity methods using a centrifugal concentrator and a concentration table. Conclusions. In the course of pyrite deposit copper-zinc ore beneficiation at the dressing mill, the effect of circulating concentration of gold in the coarse copper concentrate regrinding cycle was established. The results of studies on the centrifugal concentration of gold in a centrifugal concentrator with further secondary cleaning of its heavy fraction on a concentration table show the possibility of obtaining a gravity product with a mass fraction of gold up to 200 g/t under its operational extraction up to 29%. It was noted that the integrated flotation-gravity technology for copper-zinc ore beneficiation will increase the through extraction of gold into marketable mineral products by more than 1.5%. The use of a combination of butyl potassium xanthate and FRIM-2920 reagent-collector in the copper-zinc pyrite ore flotation technology contributes to increased extraction of copper and gold into copper concentrate by 0.87% and 3.22%, respectively, and zinc into zinc concentrate by 0,4%. Increasing the pulp temperature in the zinc flotation cycle to 40–45 °C and returning the control zinc flotation concentrate and tailings from the first cleaning flotation of zinc to the II main zinc flotation allows increasing the mass fraction of zinc in the zinc concentrate from 48.5 to 51.1% under a simultaneous increase in the extraction of zinc into zinc concentrate from 62.6 to 65.6%.

Purpose of the work. Rational subsurface use implies the most complete and comprehensive development of mineral reserves. In this regard, the aim of the study is to determine the possibility of obtaining metallic magnesium from the ores of the Kaliningrad-Gdansk salt basin, along with planned potassium sulfate and magnesium sulfate production. Methods. In the course of the study, ore samples were selected, the existing technologies of polymineral (kainite, carnallite and kizerite) ore processing are analyzed, a technological process for obtaining metallic magnesium from the available ore raw materials and by-products of the main production was developed, tests were organized to obtain metallic magnesium by electrolytic means based on the Nivenskoye deposit ore, the quality of the obtained material was evaluated, the possibilities of creating production in Kaliningrad region based on the available raw materials were analyzed. Results. As a result of the development of raw material processing technology and laboratory tests, the possibility of obtaining metallic magnesium from polymineral (carnallite) ores of the Kaliningrad-Gdansk salt basin has been established. At the same time, it was revealed that the production of magnesium by the electrolytic method is complicated by the presence of a high concentration of sulfate ions in the initial processed raw materials, which requires the inclusion of the desulfatization stage in the technological process. Conclusions. Natural carnallite ores of the Kaliningrad-Gdansk salt basin, as well as the obtained by-products arising during the main technological process (production of potassium sulfate), can be used for the production of high-quality metallic magnesium according to GOST 804–93 quality level. The results of the study make it possible to develop the natural resources of the polymineral ores of the Kaliningrad-Gdansk salt basin in the most comprehensive way, obtaining a wide range of products, including metallic magnesium.

The purpose and relevance of the work. Intensive industrial development, dependent on fossil fuels, has led to a critical accumulation of atmospheric carbon dioxide and an increase in the temperature of the Earth’s surface. A further increase in the planet’s temperature by 2 °C could lead to a rise in global sea level by 6 meters, which will cause an increase in the number of floods and hurricanes, and the melting of permafrost will pose a threat for polar cities infrastructure. All these factors will lead to significant losses, so the decision to decarbonize is in Russia’s national interests. The purpose of the research is to find ways to reduce harmful emissions in the mining industry. Methodology. Based on the reported data, a critical analysis and study of the possibilities of reducing greenhouse gas emissions in the process of mining is carried out. Results and scope. The mining industry is the main source of raw materials for the manufacturing industry, transport, metallurgy, construction and energy. The decrease in the content of useful components in the ore makes it necessary to extract, load, transport and process more materials. In the short term, it is not possible to phase out fossil fuels, but the main methods of a mining companys decarbonization strategy can be considered: on-site power supply, reduction of diesel fuel consumption for rock transport, improved processing technology, carbon capture and storage. For this, the mining industry can use various reserves in the form of environmentally friendly energy solutions, such as energy efficiency, energy recovery, renewable energy and carbon capture. Conclusions. The mining industry can use various clean energy solutions such as energy efficiency, energy recovery, renewable energy and carbon capture. A complete solution to the energy challenges facing the mining industry will require a combination of clean energy technologies.

We fabricate three-terminal hybrid devices consisting of a semiconductor nanowire segment proximitized by a grounded superconductor and having tunnel probe contacts on both sides. By performing simultaneous tunneling measurements, we identify delocalized states, which can be observed from both ends, and states localized near one of the tunnel barriers. The delocalized states can be traced from zero magnetic field to fields beyond 0.5 T. Within the regime that supports delocalized states, we search for correlated low-energy features consistent with the presence of Majorana zero modes. While both sides of the device exhibit ubiquitous low-energy features at high fields, no correlation is inferred. Simulations using a one-dimensional effective model suggest that the delocalized states, which extend throughout the whole system, have large characteristic wave vectors, while the lower momentum states expected to give rise to Majorana physics are localized by disorder. To avoid such localization and realize Majorana zero modes, disorder needs to be reduced significantly. We propose a method for estimating the disorder strength based on analyzing the level spacing between delocalized states.
On the boundary conformal field theory approach to symmetry-resolved entanglement
Authors: Di Giulio Giuseppe , Meyer René , Northe Christian , Scheppach Henri , Zhao Suting
Published: July 2023

We study the symmetry resolution of the entanglement entropy of an interval in two-dimensional conformal field theories (CFTs), by relating the bipartition to the geometry of an annulus with conformal boundary conditions. In the presence of extended symmetries such as Kac-Moody type current algebrae, symmetry resolution is possible only if the boundary conditions on the annulus preserve part of the symmetry group, i.e. if the factorization map associated with the spatial bipartition is compatible with the symmetry in question. The partition function of the boundary CFT (BCFT) is then decomposed in terms of the characters of the irreducible representations of the symmetry group preserved by the boundary conditions. We demonstrate that this decomposition already provides the symmetry resolution of the entanglement spectrum of the corresponding bipartition. Considering the various terms of the partition function associated with the same representation, or charge sector, the symmetry-resolved Rényi entropies can be derived to all orders in the UV cutoff expansion without the need to compute the charged moments. We apply this idea to the theory of a free massless boson with U(1)U(1), \mathbb{R}ℝ and \mathbb{Z}_2ℤ2 symmetry.
Implications of Sharia-compliant financing trade-offs on unemployment and growth
Authors: Budi Cantika Yuli Sri , Rofik Mochamad
Published: July 2023

As a Muslim-majority country, Indonesia possesses significant potential to harness Islamic banking as a key driver of its economy. This study aims to examine the effects of Sharia-compliant financing provided by Islamic banks in Indonesia on the unemployment rate and economic growth. The analysis utilizes data on Sharia-compliant financing for non-bank third parties, open unemployment rate, and gross regional domestic product at constant prices as proxies for economic growth. Annual panel data from 33 provinces in Indonesia covering 2010 to 2021 are employed. The analysis employs a fixed-effect regression model using the generalized least squares (GLS) estimator. The findings of this study indicate that Sharia-compliant financing has a positive impact on reducing the unemployment rate and fostering economic growth. However, it is observed that the effectiveness of Sharia-compliant financing in reducing unemployment diminishes as the share of such financing increases. Conversely, a higher market share of Sharia-compliant financing is associated with a more significant role in promoting economic growth. These findings highlight a trade-off between the impact of Sharia-compliant financing on growth and unemployment, suggesting that although growth driven by Sharia-compliant financing in Indonesia is present, it may need more inclusivity and more optimal job creation.

The importance and benefits of strategic management in the business sphere are declared in studies worldwide. It represents an extensive area for research. The purpose of this paper is to evaluate the strategy formulation activities as well as the strategic management tools and techniques used by Slovak companies. Data on 365 manufacturing companies were obtained through an online questionnaire during 2020–2021. Selected methods of inductive statistics helped to analyze the data (the Pearson chi-square test and interval estimates for population proportion). The results show that the potential of analyzed strategy formulation activities is not filled in the Slovak companies. Enterprises only perform certain activities, and attention is focused mainly on setting strategic goals. It prevails a small orientation to sustainable development in strategic goals (only 22% of enterprises). The most used strategic management tools and techniques consist of an analysis of company resources, SWOT analysis, and customer satisfaction. From the point of view of the manufacturing area, no significant differences are defined in the use of the tools. The future management directions should include a variety of strategic management tools from the external environment. At the same time, the given tools should be supplemented with newer strategic tools ensuring flexibility and adaptation to dynamically changing conditions.
