Giao dịch dân sự là hợp đồng hoặc hành vi pháp lý đơn phương. Thông qua các giao dịch dân sự, chủ thể xác lập các quyền lợi và nghĩa vụ để thỏa mãn các nhu cầu nhân sinh. Nhưng không phải giao dịch dân sự nào cũng đương nhiên có hiệu lực, có những giao dịch dân sự sẽ bị vô hiệu nếu không thỏa mãn được các điều kiện luật định. Khi giao dịch dân sự vô hiệu, các chủ thể phải khôi phục lại tình trạng ban đầu, hoàn trả cho nhau tài sản đã nhận. Nhưng thực tế, rất nhiều trường hợp, tài sản - đối tượng của giao dịch dân sự ban đầu đã được đem ra thực hiện một giao dịch khác với người thứ ba và người thứ ba hoàn toàn thiện chí và ngay thẳng khi tham gia vào giao dịch đó. Trường hợp này, pháp luật gọi họ là người thứ ba ngay tình. Nếu rơi vào trường hợp là người thứ ba ngay tình, khi giao dịch dân sự vô hiệu thì vấn đề họ rất quan tâm là quyền lợi của họ sẽ được bảo vệ như thế nào? Người thứ ba ngay tình có được giữ lại tài hay phải trả lại cho chủ sở hữu, người chiếm hữu hợp pháp…? Đây cũng chính là những vấn đề pháp lý mà tác giả sẽ làm rõ trong phạm vi bài viết này.

O agravamento da pandemia de Covid-19 no México, logo no início de 2021, fez crescer a demanda por oxigênio e insumos na capital. A urgência por esses itens básicos decorreu do  aumento da taxa de ocupação dos hospitais públicos e privados, ocasionando o desabastecimento e aparecimento de vendedores clandestinos ofertando os produtos a preços exorbitantes. Com efeito, em tempos de crise, é normal que as dimensões mais frágeis do ser humano sejam afetadas, porém, até que ponto a escassez de recursos e a luta pela sobrevivência podem influenciar no senso de justiça, ética e moral de pessoas que se encontram em situação extrema de necessidade e vulnerabilidade? A partir dos fatos apresentados, o objetivo desse trabalho é realizar uma análise crítica-jurídica e multidisciplinar sobre as condutas dos agentes –  governo, empresas fornecedoras de oxigênio e vendedores clandestinos – no “Mercado da Morte” mexicano, com ênfase na ética, moral, assim como no direito comparado. Para tanto, será usado o método de pesquisa qualitativa e quantitativa, pesquisa bibliográfica e exploratória de dados de fontes abertas. Por certo, ao final deste trabalho, restará claro que a crise provocada pelo novo coronavírus tem sido fator preponderante na determinação de comportamentos e tomada de decisões contrárias ao direito, à ética e à moral.

Published: September 2021

Purpose: Role-emerging placements in occupational therapy training are contributing to professional and workforce development because of their strong occupational focus and placement of students in emerging practice. This manuscript explores how one role-emerging placement challenged and developed student theoretical and clinical skills, presented new ways of working at the recipient site, and enhanced service delivery. Methods: The background to role-emerging placements in occupational therapy is explored through the use of a case study which reflects on and analyses how the assessment and treatment of occupation enhanced service delivery at a local, non-traditional site. Eight students in England developed and ran a psycho-education group to support the occupational needs of female service users who have experienced domestic abuse. Results There was an overall increase in self-esteem scores and an expressed increase in knowledge and understanding by participants. Students reported developing a deeper understanding of occupation, and the hosts identified the student’s clinical skills as unique contributors to service delivery. Conclusion: By focusing on occupation, role-emerging placements draw on the roots of the profession and anchor its future to the theoretical foundations of its past. However, in order to employ occupational therapists, these organisations need to understand what the occupational therapy profession can offer them.

Cystic lesions in the renal parenchyma can be attributed to several types of pathologic conditions, such as acquired renal cysts and polycystic kidney disease. Some clinical criteria are used to distinguish between these two diseases. Ultrasonography aids in the characterization of cystic lesions in the abdominal organs, allowing the diagnosis of these diseases. We hereby report the case of a young adult female capuchin monkey (Sapajus libidinosus) submitted to clinical and sonographic examination in order to evaluate its health prior to reintroducing the animal in nature. Physical examination did not reveal any type of alteration. However, the ultrasonogram disclosed the presence of some renal cysts in the right kidney, as well as a hepatic cyst. There are very few reports in the literature of the presence of renal cysts in primates.

Haor is a well-known wetland feature in Bangladesh because of its dynamic ecosystem which is changeable with the seasonal variation. The majority people of the community are critically dependent on the haor. This paper attempts to analyse the provisioning ecosystem services of Aral Haor of Sylhet District, their changes and why the changes occurred during the last 30 years since 1990 to 2020 through community assessment. The papers argues that the community based approach integrates the local people to reveal the actual scenario of the livelihood dependency on the provision ecosystem services as they are the main user of the provisioning services. Thus the primary data were collected through observation, FGD, Community Mapping and interview with experts. The study found that community the service providing area of the Aral haor have not been changed in mentionable level over the 30 years, however the shape of the haor have been changed slightly due to high sedimentation. Along with rice cultivation during dry season, natural irrigation, fishing and bird nesting were most important to provisoing services to the community which have been changes due to both natural and anthropogenic activities. The study concludes that even having importance of the Aral hoar, not any measurer has been taken by local authority to conserve the Aral hoar ecosystem services those are very vital for the livelihood of the thousands of community people living nearby.

Introduction. Heavy metals are included in one of the significant groups of ecotoxicants. Determining heavy metals at low levels is one of the main problems in analytical chemistry, which depends on various factors. Ignoring the contribution of these factors to the total uncertainty can increase the probability of distortion of the results due to an erroneous decision on the compliance of the obtained data with a particular standard. The most significant influences include the purity of reagents, dishes, and air in laboratory rooms. Purpose of the work. Search for ways of reducing the listed influences provided that the expense of time, material and labour resources are minimized. Materials and methods. In the course of the work, many experiments were carried out, including the analysis of nitric acid for the content of metals before and after cleaning by distillation, the analysis of washes from new fluoroplastic laboratory glassware and glassware that had been cleaned by steaming, an assessment of the effect of air pollution in the laboratory room based on a study of calibration curves, which were constructed at the analysis of standard iron solutions prepared in the Clean Workplace and in a conventional fume hood. All measurements were performed by inductively coupled plasma mass spectrometry on Agilent 7800 ICP-MS mass spectrometer. Results. The efficiency of the proposed methods for eliminating interfering influences on the analysis has been experimentally proved. Conclusion. The technical and analytical problem, which consists of finding optimal conditions for preparation of reagents, glassware cleaning and decreasing the influence of laboratory air pollution, allows to increase reliability of the obtained results and prevent distortion of information about the observed degree of environmental pollution.

Published: September 2021

Introduction. In connection with the widespread introduction of new preparative forms of pesticides and methods of their introduction into the environment, the urgent task of the modern period is to minimize the risk of exposure to pesticides on the health of workers and the population-the use of diflubenzuron of low and medium toxicity increases. Therefore, a mandatory criterion for assessing risk is registration tests, carried out during several stages - as hazard identification, hazard characterization, exposure assessment, risk characterization. Purpose of work. To assess the regularities of the formation of the risk of diflubenzuron by exposure and by the absorbed dose, depending on the type of preparative form of pesticides with different technologies of their introduction and regulating safe use measures. Materials and methods. The obtained exposure levels of insecticides based on diflubenzuron in the air and on the skin were compared with the hygienic standards calculated and experimentally established as follows: MPC (mg/m3) in the air of the working area and approximate admissible level (AAL) (mg/cm2) of skin contamination. The exposure level risk was determined by the safety level (SL) SLsumm value. The risk of exposure to insecticides based on diflubenzuron for the operator / user / refueller / pilot / signaller based on the absorbed dose, determined by the safety factor - SLp, and the exposure -SBsumm, is considered acceptable when SLsumm and SLp <1. Results. The paper presents the risk analysis results of the impact of diflubenzuron-based insecticides studied in natural conditions using 27 drugs with different preparative forms and methods (technologies) of their introduction into the environment. The risk of exposure to insecticides (SLsumm) for all technologies is acceptable SL. The risk of absorbed dose (SLp) was more significant regardless of the type of formulation. Wettable powder formulations are more unfavourable to use than other formulations. Conclusion. The conditions for the use of preparations based on diflubenzuron in the technologies of ground boom spraying and fan spraying of field and horticultural crops, in the treatment of field and forest crops by the aerial method, in the treatment of field and horticultural crops in private household plots, in the treatment of champignons in protected ground, compliance with regulations and measures safety meet hygienic requirements.

Introduction. At the current stage of hygienic evaluation, the substantiation of at least approximate safe concentrations in the ambient air of populated areas for nanoparticles is an up-to-date challenge. Its persistence dissolves the guidelines for risk management and divests the supervisory bodies of legal support. A comparative toxicological evaluation of the studied substance and its chemical analogue is one of the guidelines for the academic substantiation of the hygienic standards for the permissible content of hazardous substances in the air. It already has previously defined exposure standards. Materials and methods. To investigate the cytotoxicity of the studied particles, a shift of the cellular composition of the bronchoalveolar lavage fluid (BALF) was used. Also, some biochemical measurements of the BALF supernatant were investigated. Outbred female rats were instilled with a suspension of particles in the volume of 1 ml of various concentrations in the form of an intratracheal suspension. Distilled water was used as a solvent. Statistical analysis of the data obtained was performed using the Student’s t-test. Results. The comparative assessment of the cytotoxicity of an original industrial aerosol containing 72% amorphous silica with an average particle size of 90 nm (SiO2 IA) was performed. It also included engineered particles of amorphous silica with an average size of 43 nm (SiO2 NPs), a commercial, an industrial sample of 100% amorphous silica with a particle size of 5 to 60 nm (amorphous SiO2), and a reference sample of standard quartz DQ12 in a volume of 1 ml of water suspension. Under the findings of changes in the cellular composition of the bronchoalveolar lavage fluid 24 hours after the intratracheal instillation of these particles, it was revealed that the biological power (in terms of the NL/AM ratio) of both SiO2 NPs and amorphous SiO2 is statistically much higher than the industrial aerosol under study. It is also higher than the standard quartz dust DQ12. In this regard, the cytotoxicity of SiO2 IA may be explained by the predominant content of amorphous silica nanoparticles in it. Conclusion. Under the obtained results, the appropriateness of using indicative safe exposure levels (ISEL) of 0.02 mg/m3 for amorphous silica needs to be reviewed. The safe reference level of impact guideline does not contain data concerning the particle size and the percentage of amorphous SiO2 in the aerosol. Nevertheless, it is impossible to pollute the ambient air with an aerosol containing only this substance.

Authors: Klimkina Kristina V. , Lapko Inna V.
Published: September 2021

Introduction. Unfavourable factors of the working environment affect bone tissue, increasing the risk of developing osteoporosis in workers of harmful industries, which is an urgent social and hygienic problem due to the high prevalence and severity of medical and social consequences. The aim of the study was to investigate the impact of industrial vibration and physical overload on the markers of bone metabolism in industrial workers. Materials and methods. One hundred fifty-two employees of mining and mechanical engineering enterprises in contact with industrial vibration and physical overload were examined. The assessment of bone tissue metabolism in the workers was carried out by the method of solid-phase enzyme immunoassay to determine biochemical markers of bone metabolism: bone alkaline phosphatase, osteocalcin, C-terminal serum telopeptide, cathepsin K, as well as indicators of calcium-phosphorus metabolism. X-ray densitometry was used to assess bone mineral density. Results. There was a significant decrease in the markers of osteogenesis: the concentration of CSF (14.26 ± 4.13 and 18.69±5.28, respectively, p< 0.05) and osteocalcin (12.23±4.15 and 17.84±5.17, respectively, p < 0.05) and an increase in the markers of bone resorption: the level of beta-CrossLaps (0.629±0.162 and 0.361±0.095, respectively, p = 0.002) and the level of cathepsin K (12.49±5.28 and 0.59±0.02, respectively, p < 0.001) in workers of industrial enterprises exposed to physical factors of production. The correlation between the markers of bone metabolism and the experience of exposure to adverse working conditions was established. Conclusion. Combined exposure to physical labour factors is a predictor of calcium-phosphorus metabolism and bone metabolism disorders, increasing the risk of metabolic osteopathy in industrial workers.

Introduction. The main point is the influence of a complex of chemical and physical stressors on agricultural machine operators. The processes of occurrence and interaction of harmful factors are probable. Markov processes are a convenient model that can describe the behaviour of physical processes with random dynamics. Purpose of the work: was to develop a probabilistic model of risk assessment for agriculture workers during the application of pesticides based on Markov processes’ theory and evaluate with the help of the developed model the probability of occurrence, the degree of severity and the prediction of the different influence of adverse factors on the operator. Materials and methods. The mechanized treatment of pesticide is presented in the form of a system, the states of which are ranked according to the degree of danger to the operator: from non-dangerous to dangerous. The transition occurs under the influence of negative factors and is characterized by the probability of pij transition. Based on the marked graph of the system states, a stochastic matrix P[ij] of transition probabilities was constructed in one step. There are formulas by which it is possible to calculate the state of systems in k steps for a homogeneous and non-homogeneous Markov chain. Results. Based on Markov chains’ theory, the system’s behaviour is modelled when using single-component preparations based on imidacloprid for rod spraying of field crops. Received vector of probabilities of possible hazardous conditions for the employee after each hour of spraying within 10 hours. After 6 hours of working, the probabilistic risk for the operator to stay in a non-dangerous state is about 50 %, and the probability risk of going into a dangerous - at 24 %. The stationary probability distribution results show the inevitability of the transition to a hazardous state of the system if enough steps have been taken. Conclusion. With this model, you can supplement the operator’s health risk assessment system, analyze, compare and summarize the results of years of research. The calculated statistical probabilities can be used in the development of new hygiene regulations with using pesticides.

According to current study, individuals with cancer who have a gene mutation have a bad prognosis. Young women with breast cancer had a poorer prognosis than older women, although it is unknown if the p53 gene mutation contributed to this. Due in part to the devastation of cancer, the appropriate technology may help cancer sufferers in regaining their lives. Researchers seek for mutations in cancer-causing gene sequences in order to identify the precancerous stage. While genetic testing may be used to forecast some kinds of cancer, there is presently no effective technique for identifying all cancers caused by TP53 gene mutations. It is one of the most often discovered genetic anomalies in human cancer is a malfunction in the action of the protein P53. As a consequence, the Universal Mutation Database is used to identify gene mutations (UMDCell-line2010).

The issue is that, although many basic databases (for example, Excel format databases) exist that include datasets of TP53 gene mutations associated with disease (cancer), this huge database is incapable of detecting cancer. Thus, the purpose the objective of this study is to create an approach for data mining that utilizes a neural network to ascertain the pre-cancerous state. To begin, bioinformatics techniques such as BLAST, CLUSTALW, and NCBI were used to determine whether or not there were any malignant mutations; second, the proposed method was carried out in two stages: to begin, bioinformatics techniques such as BLAST, CLUSTALW, and NCBI were used to determine whether or not there were any malignant mutations; and third, the proposed method was carried out in two stages: to begin, bioinformatics techniques such as To begin, bioinformatics tools such as BLAST and CLUSTAL

Vote Algorithms were utilized to classify pre-cancer by malignant mutations in the disease's early stages. The writers teach and evaluate their subjects using a variety of situations, including cross validation and percentages. This page contains a review of the algorithms discussed before.

According to the Alcohol Scale, 61.3% of the participants were in the non-addictive group, and 63.3% were in the risk group according to the Internet addiction scale. 2.7% of the participants were e-bullies and 2.3% were e-victims. There was no correlation between the Alcohol Addiction and the Internet Addiction scores of the participants (p>0.05), while a weak positive correlation was detected between the e-bullying and e-victimization scores (for each; p <0.05). A positively weak correlation was found between the Internet Addiction score and e-bullying and e-victimization scores (p <0.05 for each). Our results suggested that students with any type of addiction have a higher risk for other types of addictions (substance-behavioral) as well.

Ethical and Social Challenges in Research with Children Exposed to Forced labour, Exploitation, and Trafficking
Authors: Agyare Patrick
Published: September 2021

This article explores the ethical and social challenges in research with children exposed to forced labour, exploitation, and trafficking. It examines whether the participation of children in evidence generation has the potential to affect them and how the researcher avoids potential discomfort. This requires investigating the multiple issues and contexts that affect the children. Essentially, conducting a child-centred evidence generation is ethically reasonable based on how such investigation is carried out and on how a child is affected by the research activities. The process of recruiting participants, avoiding potential harm, ensuring privacy, anonymity and confidentiality corresponds to the best possible regulation, in full respect of the interests of children. What is pursued is a child-centred evidence generation, capable of responding in an acceptable way, from an ethical point of view to the question about the methodology of the research itself. In addition, child-centred research enhances the sharing of perspectives and insights, which break down the barriers of exclusion. Against this background, this article contributes to the identification, interpretation, and clarification of ethical and social questions that arise in relation to child-centred evidence generation. Similarly, it furthers awareness on the significance of ethical reflection and in making informed decisions and choices to mitigate against potential harm to participants during and after the research.

Gender distribution in all creatures is a sign of Nature. For human guide it seems to realize the gender division that is found distinctive in physical nature, man and woman with entirely different physique, that all other religions admit the difference but their societal customs have counted on equal gesture. That is the reason modern societies are now viewing no problem at homosexual contact in the west, without ascertaining the results of failures in saving their nation from a purgatory desire in their youth, who have forgotten how to quench their natural thirst from the right way, of having marriage with opposite gender. This study will explain how west has allowed doing homosexuality, contrary to which no religion has allowed freedom against the natural way. Islamic teachings are proactive in restricting these kinds of illegal trails for the safety human folk. Conclusively it is clarified that due to denial of religious teachings, there are arising big issues of gender-wise sins in the world that is also arresting Muslim youth too. Therefore, only the religious theories are advisable to all humankind for safety of human-identity. Thus, Islam teaching can never allow promoting the western’s theories of ‘sexuality’ amongst Muslim community.
