Authors: Yamaguti Mateus Xavier , Cruz Ricardo Souza , Neto João Teles de Carvalho
Published: November 2023

Este trabalho consiste na proposta de uma Tecnologia de Informação e Comunicação (TIC) para apoiar o ensino presencial ou a distância de instrumentação básica – paquímetro e micrômetro – nas disciplinas introdutórias de Física Experimental. A TIC consiste em dois simuladores desenvolvidos nas linguagens HTML/Javascript com possibilidades para uso em qualquer sistema de gestão de aprendizagem, sendo que tornamos públicos os códigos e procedimentos para implementação almejando a plataforma Moodle utilizada pelo Ambiente Virtual de Aprendizagem da Universidade Federal de São Carlos (UFSCar). Os simuladores podem ser usados tanto durante o processo de ensino quanto no processo de avaliação dos estudantes. De forma a avaliar a efetividade da proposta, incluímos o relato de experiência do uso desta TIC em quatro ofertas de disciplina para os cursos de Licenciatura em Ciências Biológicas, Licenciatura em Física e Licenciatura em Química do câmpus de Araras da UFSCar. Utilizamos os Três Momentos Pedagógicos de Delizoicov como metodologia de ensino. Por fim, argumentamos que a TIC aqui apresentada pode auxiliar no ensino de instrumentação básica em Física para cursos nas modalidades a distância, presencial ou híbrida.

Published: November 2023

Abstract This study evaluates the impact of technical assistance and rural extension provided by the Dom Hélder Câmara Project (PDHC II) in the Brazilian semiarid region, which aimed to reduce the poverty levels and inequalities in the region, qualifying family farmers to develop sustainable production and encouraging the replication of good agricultural practices. Using the propensity score matching method, 16 different indicators of the assisted families and the control group were analyzed, involving monetary and nonmonetary incomes. The results indicate that the program was successful in benefiting poor or extremely poor families in this region, providing technical assistance and rural extension and, for a fraction of them, access to the Rural Funding Program. In addition, PDHC II achieved its objectives of providing an increase in agricultural production and in the income of the beneficiaries, with an even more prominent impact among those who received remittances from funding program. It can be concluded that technical assistance and rural extension were effective, benefiting poor family farmers in the Brazilian semiarid region and having a larger impact when associated with productive funding resources.

Published: November 2023

Resumo O objetivo da presente pesquisa é investigar o modelo dos shadow prices na sensibilidade dos preços, nos níveis tecnológicos e produtivos e seus impactos na coordenação da cadeia produtiva de feijão-comum. O modelo dos shadow prices considera o produto marginal da produção de feijão e a capacidade de processamento de duas plantas industriais. Os dados de produção marginal foram levantados nos municípios goianos de Cristalina, Joviânia e Morrinhos, locais onde foi utilizado o sistema de amostragem por conveniência, com a escolha de 50 produtores (20 em Cristalina, 15 em Joviânia, e 15 em Morrinhos). Tais dados foram levantados nos registros das agroindústrias em Cristalina, Goiânia e Joviânia. A capacidade de processamento foi baseada nas plantas industriais localizadas em Cristalina e em Goiânia. Os dados apontam que o nível tecnológico e a oscilação dos preços são os principais causadores de shadow prices, sendo que eles contribuem para a não coordenação da cadeia e a geração de margens excedentes dentro da cadeia produtiva em si. O modelo de shadow prices apresentou boa adequação para a presente análise, indicando que os modelos de coordenação que são adotados são pertinentes para o funcionamento da cadeia produtiva do feijão.

ABSTRACT Objective: To evaluate the effect of thermocycling on the Knoop internal microhardness of high- and low viscosity bulk fill resins applied in Class I cavities. Methods: Thirty third molars with Class I cavity preparations were randomly divided into 3 groups according to the restorative system: nanoparticulated composite resin (Filtek™ Z350 XT 3M ESPE) (oblique increments of 2mm); low viscosity bulk fill resin (Filtek™ Bulk fill Flow, 3M ESPE) (3mm increments covered with a 1-mm layer of nanoparticulated resin); high viscosity bulk fill resin (Filtek™ Bulk fill, 3M ESPE) (single 4-mm increment). After 24h, half of samples was submitted to thermocycling (1,000 cycles). All samples (n=5) were sectioned in half to measure the internal microhardness at bottom and top of restoration. Results: Analysis of variance indicated that, for nanoparticulated composite resin, without thermocycling, the microhardness at the top was statistically lower than at the bottom. After thermocycling, there was no difference in microhardness between the top and the bottom. For low viscosity bulk fill resin, without thermocycling, there was no significant difference in microhardness means between the top and the bottom. After thermocycling, significantly higher microhardness was found at the top than at the bottom (p <0.05). For high viscosity bulk fill resin there was no significant difference between the microhardness values at the top and bottom, regardless of thermocycling (p> 0.05). In all composite resins, an increase in microhardness was observed after thermocycling (p <0.05). Conclusion: Thermocycling increased the internal microhardness of resin restorations, and, for the low viscosity bulk fill resin, the microhardness at the top was higher than at the bottom after thermocycling.
Estética das identidades: sobre a política em torno das representações no digital
Authors: Silva Tarcisio Torres
Published: November 2023

Resumo Este texto tem como intuito compreender as políticas de identidade brasileiras que emergem de um incessante jogo midiático, em que causas sociopolíticas são fundidas com opções estéticas oferecidas por rostos falantes de influenciadores e elementos de design em plataformas de mídias sociais. Com isso, a política se funde com a estética, transformando a maneira como se orienta a formação cidadã, principalmente entre jovens e adolescentes. Partindo de discussões clássicas em torno das identidades e da estética entendida como potencial político, observaremos como esses fenômenos aparecem no digital. Para tanto, utilizamos como estudo de caso dois exemplos relacionados à comunidade LGBTQIA+ no Brasil: Rita Von Hunty e Erika Hilton. Como resultado, observamos que a estetização das identidades, apesar de constituir um fenômeno contemporâneo próprio da visualidade dos ambientes digitais analisados, pode também reivindicar espaços de poder em que a imagem tem papel significativo.
Análises sobre a ocupação do solo em áreas urbanas de preservação permanentes e suscetíveis à inundação: estudo de caso no Vale do Itajaí, SC
Authors: Schorn Filipe Amândio , Vieira Rafaela
Published: November 2023

Resumo As ocupações informais são uma realidade na Bacia Hidrográfica do Rio Itajaí (BHRI) em Santa Catarina, ocasionando o uso de áreas ambientalmente frágeis e propensas a se tornar inundáveis. O objetivo do estudo foi diagnosticar a ocupação do solo em áreas de preservação permanentes e suscetíveis à inundação no município de Indaial, situado na BHRI e discutir aspectos ocasionados por essas ocupações. Foram utilizados, o referencial teórico-metodológico, aparato legal e contexto físico-territorial. Adotou-se a metodologia utilizada por Varallo et al. (2016), definindo zonas de prioridade para preservação ambiental e restrição à ocupação urbana. Foi utilizado o software Arcmap 10.1 para o cruzamento das variáveis: APPs do rio Itajaí-Açu, áreas suscetíveis à inundação indicadas pelo modelo HAND e projeção horizontal da densidade construída. De um total de 1197,24 hectares de área de interesse, 14,9% se apresentam com alta prioridade para preservação ambiental, 51,9% com médio potencial e 33,3% resultaram em baixa prioridade. As discussões e análises realizadas permitem considerar que os efeitos de das inundações, são mais fortemente observados em populações que ocupam áreas susceptíveis à esses eventos, evidenciando a necessidade de gestão do uso dessas áreas.
Redes Pluridomiciliares de Suporte Social em Cacoal (Rondônia, Brasil)
Authors: Cunha Tiago Augusto da , Daniel Dorys Mirella Bohn , Miyasaka Elza Luli
Published: November 2023

Resumo Os conceitos de família e domicílio transformam-se e influenciam-se constantemente ao longo do tempo e do espaço. Mais recentemente, está em jogo uma relação inversamente proporcional entre ambos. De um lado, o aumento do número de domicílios. De outro, a diminuição do número de seus integrantes. É relativamente comum, pesquisas domiciliares circunscreverem o núcleo familiar aos limites físicos da residência. Recortá-lo, porém, trata-se apenas de uma estratégia analítica, já que a empiria demonstra que diferentes domicílios com núcleos aparentados ou não mantêm estreita relação entre si. Compõem, portanto, uma espécie de rede de ajudas, suportes e auxílios, materiais e imateriais. Desse modo, a presente pesquisa tem como intuito versar sobre o que aqui denominamos redes pluridomiciliares e suas características. Fomos a campo mapeá-los, aplicando a abordagem de redes sociais em dois setores censitários na cidade de Cacoal, localizada no estado de Rondônia. Selecionamo-os, sobretudo, segundo a variável renda. Os dados sugerem que o tamanho, o formato e o conteúdo das Redes Pluridomiciliares de Suporte Social (RPSS) são fortemente influenciados por ela e, assim, manifestam-se espacialmente segundo predisposições locacionais, é dizer, de acordo com quesitos de proximidade físico-geográfica.
Os instrumentos jurídicos urbanos e o Programa Revitalizar como indicadores da refuncionalização nas políticas públicas para o Centro Antigo da Cidade de Salvador (BA)
Authors: Silva Juliana Santos da , Reis Lysie
Published: November 2023

Resumo O Programa Revitalizar, instituído pela Lei Municipal nº 9.215/2017, concede benefícios fiscais sobre imóveis e atividades àqueles que se dispuserem a realizar distintas formas de intervenções na Área de Proteção Cultural e Paisagística (APCP) do Centro Antigo de Salvador (CAS). Em paralelo, entende-se que o Estatuto da Cidade consolidou os instrumentos de política urbana que, se bem aplicados, podem ser redutores das desigualdades relacionadas à moradia e à ociosidade dos imóveis. A partir da revisão sobre o conceito de refuncionalização e da avaliação dos instrumentos urbanísticos do Centro Antigo, buscou-se avaliar os impactos da relação entre os imóveis deferidos pelo Revitalizar e a produção do espaço urbano no centro tradicional soteropolitano. Os principais resultados encontrados foram: não houve a consolidação de uma política pública capaz reduzir as desigualdades mediante ações de preservação do patrimônio urbano e os incentivos fiscais que, sobretudo, não atenderam às camadas populares dessa sociedade urbana, ou seja, não houve rompimento com a trajetória de acumulação de riquezas que vêm fortalecendo as classes capitalistas nacionais e estrangeiras através da tributação.
Redenção na aparência e consolo metafísico: as duas ordens de justificação da existência em O nascimento da tragédia
Authors: Mattioli William
Published: November 2023

Resumo: Neste artigo, pretendo apontar e analisar uma ambiguidade na noção de “justificação” presente na primeira obra de Nietzsche: O nascimento da tragédia. Essa ambiguidade diz respeito ao elemento psicológico e metafísico que permite que o mundo apareça como justificado mediante o processo de transfiguração, o ato de redenção e o estado de consolo metafísico, os quais se dão, seja pela descarga dos sofrimentos do Uno-primordial em aparências e imagens sublimatórias (o que ocorre pelo efeito do impulso apolíneo), seja pelo retorno ao seio materno da natureza através do rompimento do princípio de individuação (o que ocorre pelo efeito do dionisíaco). Através de uma análise de diferentes passagens em que os termos “justificação”, “redenção” e “consolo metafísico” aparecem no texto, pretendo mostrar que, num confronto com o pessimismo de Schopenhauer, Nietzsche elabora duas concepções distintas de justificação estética da existência, vinculadas a uma interpretação teleológica da natureza que admite um telos específico para cada um dos seus impulsos fundamentais.
Exploring the impact of 1-deoxynojirimycin on alpha-galactosidase activity and chickpea seed germination through in vitro experiments and molecular docking analysis
Authors: Prasanna Krishnamoorthy Vengatesh , Jenisha Jobudhas , Rathinasabapathi Pasupathi , Arunraj Rex
Published: November 2023

ABSTRACT: Seed germination is a tightly regulated physiological process. Hydrolytic enzymes provide energy that brings physiological, biochemical, and physical changes to the seed during germination. Alpha-galactosidases break down alpha 1-6 linked galactosyl groups in glycoproteins, glycolipids, and oligosaccharides into simple compounds to provide energy during seed germination. Chickpea seed germination characteristics showed that inhibition of alpha-galactosidase using 1-deoxynojirimycin (DNJ), a derivative of deoxygalactonojirimycin, delays germination. To gain insights into the mechanism of inhibition, we modeled the enzyme’s structure and performed in-silico docking of the inhibitor and natural substrates (raffinose and stachyose) to the enzyme. We also validated our model using recombinant chickpea alpha-galactosidase. Our docking studies showed that both the inhibitor and the substrates bind to the same active site pocket in the enzyme but to different amino acid residues, stachyose being a preferred substrate, and DNJ competitively inhibits alpha-galactosidase with a Ki and IC50 of 44.5 µM and 89.13 µM respectively. Delayed germination is a desirable agronomic practice that can be explored for better crop establishment and to prevent pre-harvest sprouting in crops.
Videofeedback-guided teleintervention for the family of a child with a cochlear implant: a case study
Authors: Santos Ingrid Rafaella Dantas dos , Carvalho Wanderson Laerte de Oliveira , Brazorotto Joseli Soares
Published: November 2023

ABSTRACT Interventions for parental training for families of hard of hearing children, including cochlear implant users, are identified as optimizing their developmental outcomes. In this single-case intervention study, we aim to describe the use of videofeedback in a remote environment, as well as to identify its effectiveness, based on the analysis of mother-child interaction, both for the mother's communicative behaviors and for the behaviors of the mother, receptive and expressive language of the child. Pre- and post-intervention measurements were performed, based on video analysis of the mother's interaction with the child, by blind judges, as well as through the application of assessment instruments for the child and the mother. There were 13 sessions, 3 of which were for evaluation before and after the intervention and 10 of teleconsultation sessions in which the videofeedback tool was used with the mother. Data were analyzed descriptively and inferentially, using the JT method, which determined the Reliable Change Index (BMI) and Clinical Significance. There was reliable positive change in the child's receptive and expressive language, as well as reliable positive change and clinically significant change in mother-child interaction after the 10 sessions of remote videofeedback intervention. Based on the reliable changes observed in this study, we present this model (televideofeedback) as a potential to optimize resources and efforts for therapeutic success in children's auditory rehabilitation, which should be studied in research with a rigorous method, for the broad recommendation of its use.

ABSTRACT The objective of this study was to evaluate the contribution of the organic load to Tucunduba Igarapé. The data were collected over 12 h for continuous analysis of physical variables, and every 3 h for physicochemical analysis. The cross-sectional profile and flow rate were measured using an accustic doppler current profile, and the load of organic matter was estimates using equations. Three distinct flow periods were verified, two of which were governed by the hydrodynamics of the Guamá River estuary and the other by unidirectional flow from Tucunduba Igarapé to the Guamá River estuary. The organic loads of biochemical oxygen demand (0,03 kg d-1 – 0,07 kg d-1) produced in Igarapé is greater than the contributions from the Guamá River estuary. The Guamá River estuary exerts a positive effect on the Igarapé by dispersing the produced organic loads and aiding its capacity for self-purification.

Published: November 2023

Abstract Modern non-destructive investigation techniques and computational tools for nonlinear analysis allow understanding the structural behavior and damage of existing buildings, aiming at the least possible extent of intervention. Careful and minimal intervention is essential to preserve the authenticity of the built cultural heritage. An investigation with a historical, experimental, and numerical approach was carried out in the Theatro Municipal do Rio de Janeiro, in Brazil, a building with an eclectic architecture from the beginning of the twentieth century. Its masonry domes and vault have paintings by renowned artists on their intrados and were strengthened in the 1970s. The adopted methodology was based on anamnesis, characterization and observation of the structure employing non-destructive tests, and on the assessment of its vulnerability by nonlinear analyses of calibrated numerical models. Several hypotheses of differential settlement under gravitational actions were investigated, seeking to reproduce the cracking pattern and to identify the causes of damage to the masonry domes and vault before the strengthening. The nonlinear analysis of the structure allowed to evaluate the causes of the observed damage, assess the level of safety, identify the most vulnerable parts, and characterize the collapse mechanisms, in addition to demonstrating the efficiency of the intervention measures adopted in the past.
Water infiltration in drained circular tunnels: an analytical solution and its simplification
Authors: Bi Jinfeng , Jiang Hong
Published: November 2023

Underwater tunnels are often subject to groundwater infiltration, which can pose risks both to the tunnel's safety and the groundwater environment. Analytical solutions are commonly used to estimate the rate of water infiltration in tunnels. However, there is a lack of research on the analytical solution of tunnels with drainage systems. The aim of this study was to investigate groundwater seepage in tunnels with circumferentially arranged drainage pipes. The analytical formula for estimating the inflow rate takes into account the seepage processes in the ground, primary lining and geotextile. The accuracy of the analytical solution is confirmed by comparing it with numerical results. The analytical solution's general form is simplified for tunnels with varying permeabilities of the surrounding strata and geotextiles, and a query chart is created to facilitate engineering applications. The research findings can serve as a theoretical basis and reference for the establishment of relevant specifications and the design of tunnel drainage systems.
Automated early estimation of bridge interventions, possession windows and costs
Authors: Mehranfar Hamed , Adey Bryan T , Moghtadernejad Saviz , Chuo Steven
Published: November 2023

Bridge managers need to generate a complete overview of required interventions, possession windows and likely costs 10–20 years ahead of execution. These, even if approximate, help ensure stable train schedules. With the increasing amount of available data and the increasing desire to exploit digitalisation to improve decision making, bridge managers are perfectly poised to make or improve these estimates by moving on from current qualitative methods. This paper proposes a way in the current climate to use digitalisation and existing data to generate approximate overviews of required interventions 10–20 years ahead of time, including estimates of component-level bridge interventions, possession windows, likely costs and the increases in failure risks if interventions are postponed. A demonstration is done on 41 bridges of a 25 km railway network in Switzerland. It is argued that the algorithm generates a more complete and consistent overview of component-level interventions, possession windows and costs compared with current qualitative methods. Additionally, the algorithm generates a solid basis for the initiation of detailed investigations of the bridges by engineering offices – that is, the investigations that result in the information required for scheduling an intervention, as well as estimating the type of intervention and track possession that are required.
Chetty v Perumaul (AR313/2020) [2021] ZAKZPHC 66 (21 September 2021) - A cautionary note on the self-inflicted injury of disastrous and careless cross-examination
Authors: van Coller Arthur
Published: November 2023

The Deputy Judge President of the Gauteng Local Division of the High Court recently commented on the functional interrelationship between judicial and legal professional ethics (Sutherland "The Dependence of Judges on Ethical Conduct by Legal Practitioners: The Ethical Duties of Disclosure and Non-Disclosure" 2021 SAJEJ Vol 4, Issue 1 47-64). Sutherland appropriately states that a culture of ethical conduct by legal practitioners is critical to ensure expeditious litigation and just outcomes (Sutherland 2021 SAJEJ 48). Many others also stress the general importance of professional ethics in legal education, practical legal training, and practice. Nonetheless, unprofessional, dishonourable, and unworthy conduct occurs with sufficient regularity to evoke widespread criticism of the legal profession. The Legal Practice Council listed the names of 123 legal practitioners who were either struck off the roll or suspended in 2022 for unethical conduct. The majority of reported violations were variations on well-known themes. Here some legal practitioners neglected to carry out legal work in a competent and timely manner, while others practiced and appeared in court without obtaining a practice management certificate or a Fidelity Fund Certificate. An advocate accepted instructions and payments directly from clients without a brief from an attorney and later used the details of attorneys without their consent. Some reported judgments, however, describe less common or novel examples of unethical conduct, such as defeating or obstructing the course of justice, misleading the court and forgery. In one instance, a legal practitioner placed a matter on an unopposed roll to secure a default judgment by intentionally removing the notice to oppose and the answering affidavit from the court file. This same legal practitioner assaulted and intimidated members of the South African Police Service ("SAPS") and was later interdicted from intimidating, threatening, victimising and harassing members of the SAPS and State attorney's offices.

Domestic wastewater is household liquid waste that comes from sinks, bathrooms, and wastewater from washing machines. In Johan Pahlawan Sub-district, West Aceh District, the community and government's concern is still low towards achieving environmental health where the coverage of wastewater management has not been optimized. This is shown by people who do not manage wastewater properly. One of the alternative domestic wastewater management technologies is the concept of constructed wetlands with phytoremediation techniques. This study aims to determine the efficiency of reducing wastewater concentrations using phytoremediation with Eichhornia Crassipes plants, Pandanus amaryllifolius plants and Scirpus grossus plants. After the phytoremediation process with the concept of CWs-SF and CWs-SSF, it shows that the use of pandanus has not been effective in reducing contaminant levels in domestic wastewater. While Eichhornia Crassipes and Scirpus grossus plants are much better at reducing wastewater concentrations. The efficiency of reducing BOD values with a contact time of 3 to 9 days can reduce BOD levels by 80%-91%, COD and TSS can reduce the wastewater to 89%-90%, the temperature of the wastewater has been qualified with Eichhornia Crassipes and wlingen plants with 290C, and the pH of the wastewater has increased to 7.5-8.

Published: November 2023

Numerous machining operations are required in order to manufacture standard and non-standard specimens for mechanical testing of polymers. The present work focuses on the machinability of HDPE-100 pipe to prepare the utmost regular filaments with specified thickness and width. The study is set to establish mathematical correlations between surface quality (total roughness; Rt), cutting temperature (T°), filament uniformity (L) and corresponding cutting conditions. The latter include Vc (cutting speed), f (feed rate) and ap (depth of cut), combined with tool geometry (i.e., rake angle: γ and cutting-edge angle: κr). A mixed Taguchi L18 plan is adopted to organize and process the experimental runs. ANOVA and RSM (Response Surface Methodology) are employed to construct prediction models and optimize subsequent machining results. It is found that T (cutting temperature) and surface roughness criteria (Ra, Rt) are strongly affected by f and Vc. In addition, ANOVA results related to the height of filament bends (L) are likewise studied as a function of tool angles γ and κr. It is noted that cutting process is influenced by κr as it explains ~19% contributions of the total variation of parameter L, while γ, Vc and f show a little influence. It is deduced that optimum input parameters, represented by Vc, f, ap, γ and κr, are respectively 160 m/min, 0.5 mm/rev, 4 mm, (-6°) and 90° when turning tough HDPE material.
Performance Analysis of Cross-Assembly of Metatranscriptomic Datasets in Viral Community Studies
Authors: Bukin Yu.S. , Bondaryuk A.N. , Butina T.V.
Published: November 2023

We conducted a comparative analysis of individual and cross-assemblies of several metatranscriptomic data sets to study viral communities using several metatranscriptomes of endemic Baikal mollusks. We have shown that, compared to individual dataset assemblies, a Hidden Markov Model-based cross-assembly procedure increases the number of viral contigs (or scaffolds) per sample, the number of virotypes identified, and the average length of scaffolds per sample. The proportion of assembled viral reads from the total number of reads in samples is higher in cross-assembly. De novo cross-genomic assemblies combined with a virus identification algorithm using Hidden Markov Model present the data in a table with the number of reads from different samples for each scaffold. The table allows comparison of samples based on the representation of all viral scaffolds, including those not taxonomically identified, i.e. those that have no analogues in the NCBI RefSeq database. Thus, cross-genomic assemblies allow for comparative analyzes taking into account the latent diversity of viruses. We propose a pipeline for metatranscriptomic data analysis using de novo cross-genomic assembly to study viral diversity.
Climate Change and Institutional Resilience in Arctic Environmental Governance
Authors: Stokke Olav Schram
Published: November 2023

This article highlights recent successes and failures in efforts to manage Arctic marine living resources to improve our understanding of institutional resilience—that is, the ability of cooperative institutions to maintain their performance despite severe disruptions to their operating environments. Rising ocean temperatures and other impacts of climate change may alter the spatial distribution of fish stocks, including their relative attachment to exclusive economic zones and their availability on the high seas. As evident in the examined Arctic cases, which involve the world’s largest stocks of cod, herring and mackerel, such changes may complicate core resource management tasks, including the regulatory task of reaching an agreement among user states on quotas and other restraints that align with scientific advice. The cross-case variance in regulatory resilience to climate-related and other changes in cooperative circumstances sheds light on general propositions regarding the drivers and inhibitors of institutional resilience, including institutional characteristics and the severity of the political challenges posed by changing circumstances.
THE LIMITS OF THE PRESUMPTION OF THE LEGALITY OF A TRANSACTION AND ITS EXTENSION TO VOID TRANSACTIONS
Authors:   Taras Shevchenko National University of Kyiv, Kyiv, Ukraine, Tsiura Vadym
Published: November 2023

The article is based on provisions of current civil legislation, approaches formed in judicial practice, primarily of the Supreme Court, and achievements of domestic legal doctrine. The research is based on the interconnected use of general scientific and special legal methods, in particular methods of synthesis and analysis, formal-legal and logical-legal as well as hermeneutic methods. Based on the interpretation of the norm of Art. 204 of the Civil Code of Ukraine and the practice of the Supreme Court, in this study we substantiate that the presumption of legality of the transaction is applied to all transactions, regardless of the legal basis for declaring them invalid in the future. That is, the presumption of legality and the need to refute it, based on its nature as a legal concept, are applied in both cases: when the invalidity of the transaction is directly established by law (void transaction) or when it is recognized by the court as invalid (disputed or voidable transaction). This is indicated by the logic of the construction of Art. 204 of the Civil Code of Ukraine, which does not distinguish the grounds for the invalidity of the transaction from the point of view of the presumption of legality, stating them next to each other, as well as the conclusions of the Supreme Court, which establish the court's duty to investigate the factual circumstances with which the law connects the invalidity of the transaction, to establish their presence or absence, and, accordingly, to confirm or refute the voidness of the transaction declared by the party or interested person. This understanding of the content of the legal category of the presumption of legality of the transaction helps to ensure the predictability of relevant social relations, the stability of business turnover, and the domestic system of the law of obligations in general.
Entrepreneurial risks of property purchasers at bankruptcy tenders
Authors: Kantor N. E.
Published: November 2023

Bankruptcy tenders perform several functions that are aimed at maximizing profits, transparency of the procedure, protection of the private interests of creditors and the insolvent debtor. Contracts concluded at such auctions have significant business risks due to the high probability of their contesting by interested parties, possible legal defects of property and property rights realized at tenders, limited application of contract law to the requirements for the performance of contractual obligations in kind. Participation in the tenders means taking on entrepreneurial risks, provided that the information is disclosed in good faith by the y of bankruptcy officer. The protection of the tender winner interest is limited to the interests of the creditors of the insolvent debtor.

The article outlines the main directions of development of auditing activities at the present stage. Positively assessing the prospects for the functioning of a single market for audit services within the framework of the EAEU, the author also predicts would be difficulties in terms of additional administrative burden on auditors and audit organizations. According to the example of the study of the essence of mandatory audit, the blurring of the risk-based approach in the implementation of external control over the activities of audit organizations providing audit services to socially significant organizations has been demonstrated. The practical inconsistency of certain preventive measures within the framework of state control in the field of auditing is illustrated.
“Smart” production — the reality and vector of modernity in the context of law
Authors: Belikova K. M.
Published: November 2023

The article analyzes some elements of the way of Russia’s industry to the technological design of “Industry 4.0” through the prism of artificial intelligence, industrial Internet of things, “smart” manufacturing and robotics. The author comes to the conclusion that these practical embodiments of the idea of “Industry 4.0” already raise a number of ethical and legal questions — the need for: developing a new notion of the “source of increased danger” / “ultra-hazardous activity”; elaborating new subjects of responsibility for the harm caused; determining a person’s place in “smart” production in the context of the emergence of new, atypical forms of employment (for example, platform employment); searching for new guarantees of human employment, etc., which require answers.

One of possible ways of overcoming a takhifilaksiya to antiangiogenic medicines at patients with a neovascular age makulyar degeneration is medicine change. The short-term assessment of efficiency of change of antiangiogenic medicine in actual practice was a research objective. Two groups of examinees with a neovascular age makulyarny degeneration and indications to the 6 th injection of inhibitor of angiogenesis are created. In the first group (7 patients, 9 eyes) carried out intravitrealny introduction of an aflibercept at an interval of a month, in the second group (8 patients, 8 eyes) – each 2 months. Estimated visual acuity according to tables of Early Treatment Diabetic Retinopathy Study, thickness of the central retina according to an optical coherent tomography. At patients of the first group in 1 month after the 2 nd intravitrealny introduction of an aflibercept visual acuity significantly hasn’t changed: increase according to tables of ETDRS has made 1±6 signs. Thickness of the central retina opposite has authentically decreased (p0,05) by 137±223 microns. At patients of the second group in 1 month after the 2nd intravitrealny introduction of an aflibercept of significant changes of visual acuity according to tables of Early Treatment Diabetic Retinopathy Study hasn’t occurred (p0,05). Unlike the first group of reliable reduction of thickness of the central retina it is noted, average decrease has made 24±82 microns (p0,05). Thus change of medicine for antiangiogenic therapy doesn’t give increase in visual functions. At the same time, monthly introduction of an aflibercept leads to significant decrease in thickness of the central retina and provides significantly the best anatomic result, than introduction at an interval of two months that can affect visual acuity maintenance duration in the long term.

It was considered the influence of severity of lung injury on the course of traumatic disease in combined trauma of the chest. It is established that the extensive damage to the lung parenchyma make the greatest contribution to the course and the outcome of traumatic disease in combined injuries of the chest with lung injury. Such damage prevent normal gas exchange, leading to disturbances in the system of transport of blood gases and, as a result, hypoxemia, acute respiratory failure of different degree, as well as to the development of systemic inflammatory response syndrome. These violations occur in patients with extensive lung injury as early as within acute period of traumatic disease, and in the second and third periods are the most pronounced. This group of patients is characterized by a high incidence of visceral and generalized bronchopulmonary infectious complications, higher mortality. The pulmonary complications and sepsis are the main cause of lethal outcomes in patients with extensive lung injury. At the same time, the course of traumatic disease in its clinical manifestations, the dynamics of the severity of the condition, complications and outcomes in patients with limited lung injury is the same as in patients with Multisystem injuries of the chest without injury of the lungs. Thus, one of the main factors that have influence on the course of traumatic disease, the incidence of visceral and generalized complications, and mortality in patients with closed injury of the chest, is the volume of damaged lung parenchyma (that is, its extent), or the severity of lung injury.

With 60 lower limbs of adults studied angioarchitectonics of the dorsalis pedis artery and its main branches. We distinguished 3 variants of the dorsalis pedis artery angioarchitectonics – straight, with the medial and lateral bends. Moreover, for each of them can be characterized by specific topographo-anatomical relationships of their branches to the bones and joints of the foot. It was proved that the location of the dorsalis pedis artery trunk influence on the levels of it divergence and the amount of its branches. The morphometrical study shows a wide range of differences between the minimal and maximal values of the internal diameters of both the dorsalis pedis artery and its main branches. The average values of cured inner diameters of arteries were indicated. Grossly visible anastomoses between the branches of the dorsalis pedis artery are normally absent except for the well pronounced anastomosis revealed only between plantar branch of the dorsalis pedis artery and the lateral plantar artery.

In organotypic culture investigated the combined effect iproto-like agent cyclophosphamide and the encoded L-amino acids on the development of the processes of proliferation and apoptosis in explants of the liver tissue of Mature rats. Various amino acids, in a concentration of 0.05 ng/ml had either a stimulating or a depressing effect on the cellular proliferation in the growth zone of explants. When introduced into the culture medium of cyclophosphamide at a concentration of 1 mg/ ml was inhibition of cell proliferation due to the development of apoptosis, verified with immunocytochemical detection of enhanced expression of protein p53. Coadministration of cyclophosphamide in conjunction with each of the amino acids led to a significant decrease in the inhibitory effect of cyclophosphamide. Amino acids with charged side radical, acid from glutamic acid and arginine at a major – was able to completely eliminate the inhibitory effect of cyclophosphamide in organotypic tissue culture of rat liver. Amino acids with charged side chains can be considered as the simplest of the regulators and stimulants of physiological functions. We know that of all the physico-chemical properties of amino acids is the hydrophobicity of the side groups are important for their intermolecular interactions. Mechanisms of action of these amino acids, the cells can have universal features, which is consistent with the assumption about the participation of electrostatic and hydrophobic interactions in these processes. Thus, L amino acids can have a protective effect on the cell proliferation of the liver tissue from the toxic action iproto-like agents.

Here we report the results of comparative analysis of the heart rate variability of cadets of the educational institution of the Ministry of the Russian Federation for Civil Defense, Emergencies and Elimination of Consequences of Natural Disasters of 1st and 5th courses which entered in 2011 and in 2016. It is established, that all cadets have the prevalence of parasympathetic part of the autonomic nervous system in modulation of the heart rate. There are no significant differences between main parameters of the heart rate variability in cadets entered in 2011 and in 2016. Thus, the total spectra power of the of heart rate variability was 6854±1708 and 6885±1712 ms2/Hz, the ratios of lowand high-frequency components were 0,6±0,2 and 0,67±0,22 сonventional units, parasympathetic reactivity indexes of the autonomic nervous system (coefficient 30/15) were 1,4±0,07 and 1,5±0,08 сonventional units, respectively. After 5 years of training the graduates of 2016 (entered in 2011) had significantly improved functional state, their functional reserves were increased, and ratios of heart rate variability for professional adaptation had been formed as more effective compared with graduates of 2011 (entered in 2006). The first group has total spectra power as 8115,77±942,44 ms2/Hz, the second group – 3582,37±383,14 ms2/Hz, the ratio of lowand high-frequency components was 0,97±0,14 and 0,80±0,12 сonventional units, respectively. All of this indicates that cadets had a moderate sympathicotonia, which persisted at the level of a stable trend in the performance of the low intensity functional test (active orthostatic test). The ratios of lowand high-frequency components after the active orthostatic test were 5,0±0,75 сonventional units in group of 2016 vs. 3,28±0,59 сonventional units in group of 2011 (р0,01). The centralization index characterizing the involvement of ergotropic mechanisms of central nervous system in maintaining homeostasis for graduates of 2011 was 3,11±0,63, and for graduates of 2016 – 5,04±0,92 (р0,1), which showed the formation of steady processes related to professional and hyperadaptational background. The reactivity index of the parasympathetic autonomic nervous system (coefficient 30/15) in graduates of 2011 and 2016 was almost the same and equaled 1,40±0,04 and 1,41±0,05 сonventional units, respectively, and therefore did not significantly affect the heart rate variability.
