Published: September 2024

Проведена оценка токсичности нефтяного и нефтесолевого загрязнения агротемно-серой почвы и агрочернозема методом фитотестирования. Длина корней пшеницы оказалась более чувствительным показателем для оценки токсичности нефтезагрязнения по сравнению с показателем всхожести семян. Уровень нефтезагрязнения в 3 г нефтепродуктов (НП)/кг почвы (как максимальный) по транслокационному показателю вредности можно рекомендовать в качестве допустимого остаточного содержания в агротемно-серой почве и в агрочерноземе при отсутствии засоления.

Wheat root length was found to be a more sensitive indicator for assessing oil pollution toxicity compared to seed germination. The level of oil pollution in 3 g of oil/kg of soil (as the maximum) according to the translocation indicator of harmfulness can be recommended as an acceptable residual content in agro-dark gray soil and in agrochernozem in the absence of salinization.
Dimensional Analysis of Diffusive Association Rate Equations
Authors: Chen Jixin
Published: September 2024

Diffusive adsorption/association is a fundamental step in almost all chemical reactions in diluted solutions, such as organic synthesis, polymerization, self-assembly, biomolecular interactions, electrode dynamics, catalysis, chromatography, air and water environmental dynamics, and social and market dynamics. However, predicting the rate of such a reaction is challenging using the equations established over 100 years ago. From dimensional analysis, we can guess a series of equations including historical ones and new ones that have the correct final unit, the number of molecules associated per second, which is constructed from concentration, diffusion coefficient, and size of the molecules only. These equations are roughly divided into two groups, continuous models and discrete models. The continuous models integrate Fick’s concentration gradient in the solution near the target to calculate the association rate, and are the historical solutions reported. The discrete models integrate the probability density function of each probe that is discretely distributed in the solution. I have introduced a key concept of the nearest neighbor diffusion time to stabilize these time-dependent solutions. These models are applied to analyze a set of experimental results for comparison to achieve consistency and clarify assumptions among models.
A General Synthesis of Cyclic Bottlebrush Polymers With Enhanced Mechanical Properties via Graft-Through Ring Expansion Metathesis Polymerization
Authors: Elardo Matthew , Levenson Adelaide , Kitos Vasconcelos Ana Paula , Pomfret Meredith , Golder Matthew
Published: September 2024

Bottlebrush polymers represent an important class of macromolecular architectures, with applications ranging from drug delivery to organic electronics. While there is an abundance of literature describing the synthesis, structure, and applications of linear bottlebrush polymers using ring-opening metathesis polymerization (ROMP), there are comparatively less reports on their cyclic counterparts. This lack of research is primarily due to the difficulty in synthesizing cyclic bottlebrush polymers, as extensions of typical routes towards linear bottlebrush polymers (i.e., “grafting-through” polymerizations of macromonomers with ROMP) produce only ultrahigh molar mass cyclic bottlebrush polymers with poor molar mass control. Herein, we report a ring-expansion metathesis polymerization (REMP) approach to cyclic bottlebrush polymers via a “grafting-through” approach utilizing the active pyr-CB6 initiator developed in our lab. The resulting polymers, characterized via GPC-MALS-IV, are shown to have superior molar mass control across a range of target backbone lengths. The cyclic materials are also found to have superior mechanical properties when compared to their linear counterparts, as assessed by ball-mill grinding and compression testing experiments.

Published: September 2024

Heterohelicenes continue to attract interest for their potential applications as organic chiral materials. To keep up with the demand for novel heterohelicene structures, expedient and scaleable synthetic procedures are required. We report a ‘Mallory’ photocyclisation methodology in continuous flow for the synthesis of thia-, oxa- and azahelicenes. This procedure has been sucessfully scaled-up to 9.8 mmol and can be applied to an iterative modular synthesis.
Fast event-based electron counting for small molecule structure determination by MicroED
Authors: Vlahakis Niko , Qu Songrong , Richards Logan , Silva deMoraes Lygia , Cascio Duilio , Nelson Hosea , Rodriguez Jose
Published: September 2024

Electron counting helped realize the resolution revolution in single particle cryoEM and is now accelerating the determination of MicroED/3DED structures. Its advantages are best demonstrated by new direct electron detectors capable of fast (kilohertz) event-based electron counting (EBEC). This strategy minimizes the inaccuracies introduced by coincidence loss (CL) and promises fast, accurate structures. We use the Direct Electron Apollo camera to leverage EBEC technology for MicroED data collection. Given its ability to count single electrons, the Apollo collects high quality MicroED data from organic small molecule crystals illuminated with incident electron beam flux values as low as 0.01–0.045 e-/Å2/s. Under even the lowest flux (0.01 e-/Å2/s) condition, fast EBEC data produced ab initio structures of a salen ligand (268 Da) and biotin (244 Da). Each structure was determined from 100–degree wedge of data collected from a single crystal in as few as 50 seconds, with a delivered fluence of only ~0.5 e-/Å2. Fast EBEC data collected with a fluence of 2.25 or 3.33 e-/Å2 also facilitated a 1.5Å structure of thiostrepton (1,665 Da). While refinement of those structures appeared unaffected by CL, a CL-adjustment applied to gain-normalized EBEC data further improved the distribution of intensities measured from salen ligand and biotin crystals. However, CL-adjustment only marginally improved the refinement of their corresponding structures, signaling the already high counting accuracy of detectors with counting rates in the kilohertz range. Overall, by delivering low-dose structure-worthy data, fast EBEC collection strategies open new possibilities for high-throughput MicroED.
Different ion maps for the same substance? Glucose analysis by MS Imaging with betaine aldehyde derivatization and NEDC matrix.

Published: September 2024

Glucose is one of the most essential molecules for sustaining life thus, appropriate and trusted methods of analysis are very welcome. In our study, we have tested two ways of glucose analysis by the MALDI IMS approach: one well-known with NEDC matrix in a negative ionization mode and one developed by us with betaine aldehyde derivatization in positive ionization mode with the aid of CHCA matrix. To our surprise, even though both methods should indicate the localization of the same molecule on adjacent tissue sections and produce the same ion maps, we obtained different results. In this study, we tested the idea that maybe one of the techniques is sensitive to a certain hexose. This would be good news because it would mean having a selective technique for analyzing different hexoses. We performed the dried droplet analyses of glucose, galactose, mannose, and fructose either with betaine aldehyde derivatization or with NEDC matrix and compared the results with the analyses from the tissue. Judging from the MS/MS spectra of analyzed molecules and comparing them with MS/MS spectra from the tissue, it is impossible to distinguish between different hexoses, maybe except fructose. In the article we discussed some ideas that could be responsible for the difference in ion maps of native glucose. Moreover, we highlight the advantages and disadvantages of both analytical approaches. Nevertheless, the question of why ion maps for glucose, obtained by the NEDC matrix and betaine aldehyde derivatization are different, remains open.
Progress Towards Stable Organic Solar Cells
Authors: Tegegne Newayemedhin , Nchinda Leonato , Krüger Tjaart
Published: September 2024

Organic solar cells (OSCs) are suitable candidates for next-generation renewable energy sources due to their low cost of production and flexibility. Their power conversion efficiency has improved significantly to about 20% in both single- and multi-junction devices due to the tremendous work in optimising the synthesis of novel active-layer materials while improving device fabrication. Despite a few reports predicting a 20-year lifetime for OSC devices, their stability currently lags behind their commercialisation. This review discusses the issues that impair OSC stability and how to mitigate them. While emphasising the importance of the International Summit on Organic Photovoltaic Stability (ISOS) protocols, an overview of recent advancements in OSC power conversion efficiency (PCE) and lifetime is provided. A comprehensive list of experimental techniques for studying OSC degradation mechanisms is also extensively discussed, weighing the advantages and disadvantages of different methods. In addition, the review emphasises the importance of essential and cost-effective equipment to encourage impactful contributions especially from resource-limited laboratories, to foster a more inclusive and globally collaborative research landscape, ensuring that diverse scientific perspectives contribute to advancing the field. Finally, fundamental challenges to developing high-performance and stable OSCs are discussed along with general recommendations for improving the stability of OSCs.

El Ego Amans Entre Giro Teológico y Filosofía de la Religión
Authors: GUILLÉN GERMÁN VARGAS
Published: September 2024

O ego amans é que opera a redução erótica.Es ta impl ica o t râns i to da subjet ividadetranscendental e seu estudo genético, que desembocana crise para a individuação como experiênciaamorosa que parte de e retorna para a comunidade.Essa virada, em essência teológica, é a maneira deenfrentar a positivização do mundo da vida nocontexto das sociedades pós-industriais e póscapitalistas.Na primeira parte do artigo, examina-se apassagem do ego cogito para o ego amans; afenomenologia do ego amans; e o ego amans comosuperação do positivismo. Contudo, sempre se corre orisco de que o amor se converta em uma menção vaziade conteúdo. Como, então, procurar a vigilânciacrítica sobre a validade das asserções Ã s quais dá lugarsua enunciação? Redução indica a operação pela qualo vivido se torna esfera de propriedade, é ver como seefetua a encarnação do amor como processo deindividuação. Esta encarnação que individua acontecena dialética entre eros e ágape; esta dialética dá lugara um projeto de formação da individuação da carne.Assim, a redução erótica exige a volta em e pelaexperiência pessoal do Deus do amor, seja como eros,seja como ágape. Esses são dois pólos da experiênciado ego amans em sua constituição de sentido de simesmo e dos valores de comunidade e de cultura. Épossível pensar em toda essa operação em que seinstala o ego amans sem recorrer a um mundo da vidaque se nos dá tanto técnica quanto tecnologicamente?A hipótese que se sustenta é de que a religiãoenquanto religação exige a volta ao si mesmo naconcreção de seus processos de individuação. É, então,o indivíduo que, ao saber dizer sim ou saber dizer não Ã  técnica e Ã  tecnologia acha sua serenidade; e a acha,precisamente, porque descobre a aesthesis comoforma de voltar a criar e projetar um sentido de vidaem um mundo tecnologizado que se faz cruel e sedesumaniza em relações mecânicas, incluindo asoperações comerciais e financeiras. Daí, então, que aexperiência individuante do ego amans consista, hic etnunc, em exibir a tecnicidade como reencantamento domundo. Que fica para o ego amans como esfera deextensão de sua individuação? Em suma, a triplarelação: liberdade, mal, Deus.
Divine Command Theory and Metaethics
Authors: BONELLA ALCINO EDUARDO
Published: September 2024

I will outline an application of metaethics to the debate about Euthyphro's dilemma and divine command theory (DCT). Metaethics elucidates how we should understand what are objective moral judgments and moral truths. I argue that the normative content of morality does not depend on God’s approval/command. This is so because moral objectivity does not depend on any approval and command, what I try to show by the nature and the logic of evaluative/normative concepts (good, bad, right, wrong, ought to etc.). Other aspects related to DCT and morality are briefly debated.

Relevance. Chronic insomnia is one of the most common forms of nighttime sleep disorders. It leads to a decrease in human performance, the development of social maladjustment, and even changes in the personal sphere. Chronic insomnia can become a trigger for decompensation of somatic, neurological and mental diseases, which determines the need to find ways to overcome it. Objective. To determine the efficacy and safety of the dietary supplement Alpha-Melatonin Relax in the treatment of chronic insomnia in patients with chronic cerebral ischemia. Materials and methods. The study involved 30 patients (18 women and 12 men) with chronic cerebral ischemia of stage I and II, the average age of which was 46.12 ± 4.98 years. The course of treatment consisted of 30 days of taking Alpha-Melatonin Relax, 1–2 tablets 30–60 minutes before bedtime. Clinical and neurological symptoms were assessed and tested using the Pittsburgh Sleep Quality Index (PSQI) questionnaire, Epworth Daytime Sleepiness Scale, and the Hospital Anxiety and Depression Scale (HADS) in dynamics. Results and their discussion. The study results showed that 30-day administration of Alpha-Melatonin Relax provided a significant p≤0.05 improvement in the subjective assessment of the quality of night sleep, a decrease in the time to fall asleep, an increase in sleep duration, a decrease in the severity of emotional disorders and daytime dysfunction. Clinical and neurological follow-up of patients during the treatment course revealed a significant reduction in the severity of chronic insomnia, asthenia, and anxiety-depressive symptoms, which allows us to recommend the use of the dietary supplement Alpha-Melatonin Relax in clinical practice. Conclusions. Based on the data of a clinical-neurological and psychodiagnostic study, the statistically significant effectiveness of the dietary supplement AlphaMelatonin Relax in correcting the symptoms of chronic insomnia in patients with the initial stages of chronic brain ischemia has been proven.

Background. The work is devoted to the problem of preserving the mental health of the population of Ukraine. The emergence of stress-related mental disorders, including post-traumatic stress disorder, leads to a negative effect on families and communities, problems of mutual understanding, support and recovery. Against this background, there is no doubt about the need to implement the experience of Western colleagues in the mental health care system at all levels of care provision. The purpose of the work is to update the issue of the implementation of foreign psychotherapeutic approaches in the system of mental health care of the population of Ukraine in the conditions of war. Materials and methods. On the basis of the analysis of literary sources and information resources, a modern overview of the problem of introducing modern psychotherapeutic directions into the system of mental health protection of the population in wartime conditions was obtained. Discussion. An analytical review of pathogenetic prerequisites for the implementation of the experience of Western doctors in rehabilitation measures and psychological support measures was carried out. Implementation of strategies aimed at preventing mental illness through education, stress reduction, and development of psychosocial support can help reduce the prevalence of risk factors for the development of mental health problems. Justification of the implementation of Western experience is important for improving the provision of assistance in the mental health system in Ukraine, which will meet modern standards and take into account the peculiarities of Ukrainian culture and society.At the same time, ensuring effective rehabilitation for victims is an act of recognition of their dignity and rights to a full life. Conclusions. At the current stage, Western health care systems emphasize the prevention of mental illnesses through education, stress reduction, and the development of psychosocial support. Implementing these strategies can help reduce the prevalence of risk factors for developing mental health problems. The ability to integrate mental health care into the general medical context is a priority, as it can improve detection of mental illness, provide a comprehensive approach to treatment, and reduce stigmatisation in the society. Focusing on the scientific basis is a priority, because the proven base of Western approaches to the issue of maintaining mental health is based on scientific research and effective methods.

Posture and stress detection system using open CV and media pipe
Authors: Kolluru Vindhya Rani , Yedla Satwik Naidu
Published: September 2024

Posture and stress are two critical factors affecting a person's physical and mental well-being. Proper posture and stress management can help avoid a range of health issues. Poor posture may result in chronic discomfort, decreased mobility, and an increased risk of musculoskeletal problems. Similarly, stress can negatively impact physical and mental health, contributing to conditions such as depression, anxiety, and cardiovascular disease. Traditional methods for assessing posture and stress, including physical examinations or self-reporting, can be subjective and time-consuming. Recent advances in machine learning and computer vision techniques have enabled the development of models that automatically detect posture and stress levels from video data. In this study, a Django framework was built that incorporates models to assess posture by calculating angles between tracked distance vectors. Stress levels are evaluated based on facial features and expressions. The use of skeleton data for human posture recognition is a key research area in human-computer interaction. By employing the MSR 3D Action Dataset, 33 key skeletal points on the body are detected, aiding in posture determination. Additionally, analyzing facial features and emotions is essential for estimating stress levels. The approach relies on convolutional neural networks.

Authors: Wisdom Chigoti Kasauka , K. M. Abubakkar Sithik
Published: September 2024

The current state of Solid Waste Management in Lilongwe City underscores the need to integrate contemporary and technological approaches for more efficient waste handling, with the support of digital solutions. Despite the severity of the solid waste issue impacting various sectors, including households, businesses, industries, and agriculture, there has been minimal effort to educate communities and townships on the importance of waste separation prior to collection. Recognizing that certain types of waste can be recycled for specific purposes, such as in agriculture, is essential. There is also a need for increased individual involvement to address solid waste management challenges, aiming to shift public perception and promote sustainable waste management practices. The rapid pace of waste production, driven by industrialization and population growth, is concerning. Unauthorized dumping has led to an unpleasant environment, noxious odors, and significant health risks through contamination of land, air, and water resources. Addressing these challenges requires focusing on technology and innovative solutions to manage solid waste effectively. This approach should enhance coordination and improve waste management from the point of creation and categorization to disposal at the dumping site. Implementing such methods could help reduce public health issues related to waste mishandling in urban areas. A proposed digital waste management solution, such as a cloud-based application, could represent a significant step towards achieving effective waste management practices in the city.

Published: September 2024

Trade finance plays an important role in achieving the Sustainable Development Goals set out in the UN program for the period 2015–2030 and aimed at solving the following tasks: stimulating sustainable economic growth, productive employment and job creation, strengthening and reviving international cooperation, etc. Cross-border trade finance is based on the general principles and documents developed by the Wolfsberg Group, the International Chamber of Commerce and the International Association of Banks for Finance and Trade, which became the sources of information for the article. Its purpose is to assess the current state of trade finance, identify trends in its digital transformation and justify the advantages and limitations of using smart contracts in the field. Currently, efforts to digitalize trade finance are fragmented due to the scale and complexity of the issue. At the same time, by using innovative digital technologies, it is possible to achieve a significant reduction in the transaction costs of financial institutions, and thereby increase the availability of trade finance for applicant companies. Authors substantiate the advantages of using digital technologies for the development of the trade finance market, describe the stages of using smart contracts for those purposes and indicate the current limitations of digital trade finance solutions.
ON THE ISSUE OF THE MECHANISM OF EMERGENCY LEGAL REGULATION AND ITS MAIN ELEMENTS (ON THE EXAMPLE OF LEGAL REGIMES OF HIGH READINESS AND EMERGENCY SITUATIONS)
Authors:   V.F. Yakovlev Ural State Law University, Lifanov Dmitrii M.
Published: September 2024

The article deals with a comparative analysis of the provisions of the current emergency legislation, which stipulates the procedure for the establishment and implementation of extraordinary (special) legal regimes. It studies the acts of federal legislation regulating the legal regimes of military, state of emergency, emergency situations, counteraction to terrorism and extremist activities, as well as regional legislation on natural and man–made emergencies (a total of 93 normative acts). It also notes that the legislator (especially the regional one) approaches the issue of normative and legal consolidation of the subject of regulation in different ways, the definition and differentiation of the grounds for the introduction of extraordinary (special) legal regimes, the powers of public administration bodies and their officials who ensure the implementation of such regimes. For example, the legislation on the public protection from natural and man-made emergencies, countering terrorism and extremist activities does not provide grounds for the introduction of appropriate regimes. The author reveals a discrepancy between the normative content of the legislative acts of the subjects of the Russian Federation in terms of securing the extraordinary powers of the public administration. In order to eliminate uncertainties in the issues of correlation between the objects of legal regulation and the grounds for the introduction of extraordinary (special) administrative and legal regimes, a proposal is substantiated on the need to formulate blank legal norms defining the grounds for the introduction of extraordinary (special) legal regimes and aimed at ensuring their implementation. Based on the results of the study, a conclusion is made that it is necessary to bring into line the content of regulatory legal acts of the subjects of the Russian Federation, which give public administration bodies and their officials extraordinary powers in the field of protecting the population and territories from emergency situations. Possible directions for improving legislation in the sphere are described.
