Complement (C) is a serum protein with immunity-related functions and enzymatic activities. It can induce inflammatory responses and antibody formation following activation by substances such as pathogens. Moreover, it is a crucial molecule in the congenital immune defense system. Complement manifests earlier than immunoglobulin in the evolutionary process of fish’s immune system. Therefore, the complement system of fish is vital for congenital and acquired immunities. A complement system is a polymolecule system comprising more than 30 soluble proteins, membrane-bound proteins, and complement receptors. It can be activated through three pathways for immunoregulation, the clearance of the immune complex, etc. The liver primarily produces the fish complement C3, which is a significant component of the complement system of fishes. C3 is the hub of three activation pathways. Research works concerning the structure, generation process, expression, and functions of C3 in fishes are reviewed in this study.

Chronic diseases, which form the somatic and social deprivation of patients, imply the provision of integrated medical and social care. National health care systems are actively pursuing processes aimed at overcoming the fragmentation of health care delivery and forming a model of integrated health care. The purpose of the study. Analysis of interaction of medical organizations and continuity in the treatment of patients in rural health care in the Saratov region.

Material and methods. The authors conducted a comparative sociological study, which involved 319 physicians working in the district medical organizations of the Saratov region. The study was preceded by the construction of the medical and social portrait of the respondents.

Results. The majority (73.7 %) of the respondents assessed the degree of continuity of patient care between inpatient and outpatient facilities in the district of the region as average.

Conclusion. The study reveals the peculiarities of the organization of medical care for the rural population, which consist in the limited implementation of the principles of continuity in the management of patients, the presence of barriers to digitalization. The analysis of the degree of interaction between doctors when providing medical care to the rural population in inpatient and outpatient conditions reveals the fragmentation of rural and regional health systems.

Against the background of a steady increase in the number of oncological diseases, as well as the complexity of the primary morphological diagnosis of malignant neoplasms (MNT) and precancerous conditions, especially in the regions of the Russian Federation, in 2019, the creation of a number of Reference Centers (RCs) for immunohistochemical, pathomorphological, molecular genetic methods was initiated research within the framework of the federal project “Fight against oncological diseases”. In 2020, on the basis of the centralized pathoanatomical department of the Clinical Center of Sechenov University, the RC began its work.

 Aim. To analyze the work of the RC of Sechenov University and compare the results obtained with the tasks of the federal project.

Materials and methods. The data of histological, immunohistochemical studies from the registers of receipt of biopsy (surgical) materials and the issuance of the results of intravital pathoanatomical studies (account forms 014-2 / y and 057-y / 04), as well as data from the Telemedicine system of remote consultations, were analyzed.

 Results. For 21 months of work, the RC consulted 1476 requests received from 70 constituent entities of the Russian Federation. More than 10 % of reference diagnoses were made in a remote format through the Telemedicine system of remote consultations at the federal and regional levels using digital pathology techniques.

Conclusion. Despite the obvious need for the work of RCs, there are still a number of issues that have a signifcant impact on the quality of diagnostic processes: specialization of specifc RCs, expansion of the range of incoming clinical and morphological diagnoses. It also requires attention to regularly improve the skills of RC employees in Russian and international educational systems and to equip the RC, frst of all, with virtual resources. The experience of the RC has demonstrated the importance of a second medical expert opinion in the primary diagnosis and verifcation of the diagnosis of malignant neoplasms of various localizations for the regions of the Russian Federation, where the acute problem is the general shortage of general pathologists and expert doctors.

The extensive sharing of personal information over networks has given rise to an emerging malware industry. This has widened the scope of the organizations being vulnerable to malware - driven cybercrime. Such organized and distributed cyber-attacks can compromise the confidentiality, integrity and availability of any organization’s valuable data and resources. The endpoints (Desktops, Laptops, Mobiles, Servers, etc.) are more vulnerable and hence mainly targeted by the cyber criminals. The aim of this study is to determine the probability of such endpoints being affected by cybersecurity threats, based upon certain characteristics of the particular endpoint. Using the machine learning techniques applied in this study, like missing data analysis and imputation (Multiple Imputation), ensemble learning algorithms (Bagging and Boosting), it can be predicted that which devices/systems in an organization are likely to be infected by malwares, ransomwares or other such threats. Based on such findings, proactive measures can be taken, and cyber security strategies can be devised which can help organizations prevent losses to the tune of millions of dollars and become cyber resilient.

This paper aimed to ascertain the level of grammar and written discourse competence of BA English students. Likewise, it sought to determine significant differences in the level of grammar and written discourse competence of students when they were grouped according to sex and school of origin. Moreover, it purposed to discover the relationship between grammar competence and written discourse competence. The respondents were all 77 First Year BA English students of a state college in Negros Occidental. Employing descriptive-comparative and correlational research designs, a standardized test questionnaire was used to gather data about grammar competence, and a standardized rubric to assess written discourse competence. Mean, standard deviation, t-test and Pearson r were used to gather data. The findings reveal that the level of grammar competence of the respondents when taken as a whole was average while their level of written discourse competence was high. The male respondents and those who came from private schools had high-level grammar competence while the female respondents and those who came from public schools had average-level grammar competence. The male respondents and those who came from public schools had average-level written discourse competence. The female respondents and those who came from private schools had high-level written discourse competence. Furthermore, there was no significant difference in the level of grammar and written discourse competence of the respondents when they were grouped according to the profile variables, and there was a low positive relationship between their level of grammar competence and level of written discourse competence.

Published: March 2023

This study explored the lived experiences of the PWDs in the workplace.This research employed the phenomenological approach. Necessary data were obtained through semi-structured interview and observations. Two participants who are persons with disabilities (PWDs) and work in a public and a private sector were selected based on the criteria set in identifying participants. Through Colazzi’s method,participants’ responses were transcribed and coded for deeper analysis. Three emerging themes reflect the lived experiences of the participants:work gives them a feeling of fulfillment; inclusion in the workplace and freedom to enjoy all the rights and benefits of a regular employee significantly boost their morale and independence in the performance of assignments.Generally,their acceptance in the workplace keeps them going and inspires them to keep thinking on how to better their job performance under an environment where people do not see them as different individuals. They allow themselves to be productive just as anyone else in the workplace. They perform their work independently and they don’t see any reason to rely on others. They claim that the quality of work they render reflect their true capabilities.
Regionalização de vazões mínimas de referência e média de longa duração da bacia hidrográfica Tocantins-Araguaia
Authors:   , Alves Maria Bevilacqua
Published: March 2023

Um dos grandes desafios para a gestão dos recursos hídricos é o conhecimento da disponibilidade hídrica em regiões, onde não se tem disponibilidade de dados hidrológicos. Diante disso, uma alternativa utilizada pelos órgãos gestores brasileiros afim de se obter informações hidrológicas, é a técnica de regionalização de vazões. Uma metodologia muito utilizada em estudos e trabalhos hidrológicos, é o método tradicional proposto pela Eletrobrás em 1985, o qual consiste na identificação de regiões hidrologicamente homogêneas e na geração de equações de regressão. Por outro lado, como uma nova proposta metodológica para a regionalização de vazões, a aprendizagem de máquina vem ganhando cada vez mais espaço nos estudos hidrológicos. Desta forma, objetivou-se com o presente trabalho regionalizar as vazões mínimas de permanência em 90% e 95% do tempo (Q 90 e Q 95 ) e médias de longa duração na bacia hidrográfica Tocantins-Araguaia utilizando o método tradicional e a modelagem de aprendizagem de máquina. Na metodologia tradicional, foi utilizada a regressão linear simples, considerando três variáveis independentes: a Peq, Peq 750 e área de drenagem. Já na aprendizagem de máquina, foram utilizados seis algoritmos: Randon Forest, Support Vector Machine, K-nearest neightbor, Earth, Modelo linear e Cubist, e três parâmetros de performance: LCCC, NSE e MAE. Para cada algoritmo, foram utilizadas 203 covariáveis (morfométricas, climáticas e de superfície) sendo estas inseridas nos modelos como o valor médio e o desvio padrão em cada área de drenagem, as quais passaram por um processo de seleção. Foram identificadas na bacia, 75 estações fluviométricas distribuídas em 5 regiões hidrologicamente homogêneas. Avaliando a sazonalidade das vazões, verifica-se que a adoção da mesma como fator de otimização dos recursos hídricos, proporciona um aumento na disponibilidade hídrica na bacia do Tocantins-Araguaia. A regionalização de vazões pelo método tradicional, apresentou ótimos ajustes estatísticos, sendo a Peq e a Peq 750 as variáveis que apresentaram maior poder explicativo da variação da Q 90 , Q 95 e Q mld . No processo de seleção das covariáveis para a modelagem de aprendizado de máquina, a Peq foi a variável que se mostrou com maior importância no processo de predição das vazões para a maioria dos modelos. Dentre os modelos de aprendizagem de máquina, os algoritmos linear e Earth não apresentaram desempenhos satisfatórios. O modelo cubist foi aquele que mostrou maior habilidade no processo de predição das vazões, podendo ser uma alternativa promissora para a técnica de regionalização de vazões. No entanto, mesmo sendo um modelo menos complexo, requerendo uma menor quantidade de variáveis, a regressão linear simples pelo método tradicional, apresentou desempenho similar ao apresentado pelo cubist. Palavras-chave: Disponibilidade hídrica. Regionalização de vazões. Aprendizagem de máquina.
Theory, Practice and DFI Institutional Design: Case of the Lesotho National Development Corporation
Authors:   Peking University, National School of Development Basotho Enterprise Development Corporation, LS Makhetha
Published: March 2023

The one important aspect of the development financing institution (DFI) to serve its development mandate lies inevitably in its institutional design. In Lesotho, the Lesotho National Development Corporation (LNDC) is marked as the DFI that is instituted to give developmental policy direction in the manufacturing sector. Although the LNDC, constitutionally, is mandated to develop the manufacturing sector, there’s a need for a private sector-led economy that is particularly driven by large-scale enterprises that also require a strenuous industrial update and adequate infrastructure. Despite the importance of private sector development, the LNDC mandate does not cover the financing of large-scale enterprises. This paper, therefore, examines the LNDC’s institutional design and its financial structure, which embodies various financial institutional arrangements to meet industrial upgrade. The conclusion lies in the question of whether the Basotho Enterprise Development Corporation (BEDCO) and LNDC should be merged or whether one should be dissolved, and its operations are assigned to the existing DFI.
Beneficiation of Solutes from Solvents: A Case of Oxalic Acid, Succinic Acid and Ethylenediaminetetraacetic Acid in Carbon Tetrachloride
Authors:   Department of Chemistry, Federal University of Technology, Owerri, Nigeria, Onyeocha Veronica Ogechi
Published: March 2023

Background: This paper reports the beneficiation of Oxalic acid, Succinic acid and Ethylenediaminetetraacetic acid solutes from Carbon tetrachloride, Diethyl ether and n-Hexane solvents respectively. These solutes are the extracts obtained from the recovery from the binary immiscible solvents namely: Carbon tetrachloride-Water, Diethyl ether-Water and n-Hexane-Water that were used in accordance with the partition coefficient technique as reported by Onyeocha et. al. This technique was employed in the leaching of the specific solute from the contaminants. As described by Onyeocha et. al., the process was brought about by the diffusion equilibrium attained by the solute in the system i.e. the binary immiscible solvent(s) at a constant temperature and pressure. The spontaneous diffusion is the effect of the partition coefficient developed due to the different degrees of solubilities of the solute in the binary immiscible solvent. The partition coefficient technique is used for extraction, purification and concentration of solutes. Beneficiation is considered as the final process that brings the product (solute) to its most viable state.

Published: March 2023

Between March 1985 and March 1987, we performed 98 surgeries (96 patients) of Intramedullary Kuntscher Nailings Intensified with Cerclage Wiring (if fractures unstable) to treat the fresh closed Fractures of Shaft Femur. Accessing the fractures by Posterolateral Approach, remove soft tissues, hematoma interposing between fragments, reaming medullary canal, performing good reduction, then stabilizing by an Intramedullary Kuntscher Nail. If the fractures not stable enough, Loops of Wiring were intensified. Postoperatively,walking with crutches, and gradual weight bearing according to the extent of bone healing. Physical Therapy focused on Range of Motion (ROM) of hip, knee and ankle. Loss of follow-up: 20 patients (22 femurs). 76 patients (76 femurs) were followed-up for a mean of 27 months (6 to 108). 61 femurs achieved complete bone healing (evaluated on patients and Xrays) with no incidents.18 femurs /patients were removed Kuntscher nail after in average 32 months (22- 48). Allowing Full Weight Bearing in average after 50 days if fracture simple, after 70 days if there were additional fractures. All 13 patients who lost ROM of hip or knee more than 200 , sustained associated injuries of pelvis or legs. Reoperation: 5 femurs (5 %) including delayed and nonunion: 2 femurs (2 %), deep infection: 2 femurs (2%).Surgical fixation not stable enough needed one or more interventions: 1 case (1%). One patient remained rotational displacement 100 ; 3 others with angulation 30 -60 . Leg shortening in average 2,4cm [1-4 ] : 6 femurs ( patients) in which 2 had shortening more than 2 cm. In Vietnam at that time, for the femoral shaft fractures, Intramedullary Kuntscher Nailing with Cerclage Wiring (if fractures unstable) were resumably an acceptable good treatment.

Authors: Drouot Violaine , Berube Martine , Gannier Alexandre , Goold John C. , Reid Robert J. , Palsboll Per J.
Published: March 2023

Thirteen sperm whales were sampled, using sloughed skin, in the Mediterranean Sea during six distinct encounters. Individuals were discriminated using the results of molecular sexing, mitochondrial control region sequencing and microsatellite genotyping (3 loci). Samples from 57 specimens were available from sperm whale strandings on northern European coasts. The first ~ 200bp of the mitochondrial DNA (mtDNA) control region of each sample were sequenced and three different haplotypes were identified. The frequency of each haplotype was significantly different between the Mediterranean Sea and the eastern North Atlantic, suggesting that sperm whales in the two areas comprise different maternal entities.

Published: March 2023

A geographically isolated population of Irrawaddy dolphins was recently discovered in Malampaya Sound, Palawan, Philippines. Line-transect surveys conducted in April-November 2001 covered 884km of trackline in the entire Sound and resulted in a total population estimate of 77 individuals (CV = 27.4%), confined to the inner portion (133.7km2 ). For all Irrawaddy dolphin sightings, where ecological data were collected (n = 48), the mean temperature was 30.2°C, depth 6.5m, salinity 28.3ppt and turbidity 2.2NTUs. Significantly higher turbidity, lower salinity and shallower depth were recorded in the inner Sound compared to adjacent waters. Bottlenose dolphins Tursiops sp. (probably truncatus) were observed in waters just outside of where Irrawaddy dolphins were recorded. During the study, at least two Irrawaddy dolphins were accidentally killed in bottom-set nylon gillnets used to catch crabs, locally called matang quatro. Reports from local fishermen also indicated that as many as three additional animals may have been killed in these nets during the same period. These findings strongly suggest that the Irrawaddy dolphin population in Malampaya Sound is in immediate danger of extirpation due to low numbers, limited range and high mortality. This is the only known population of the species in the Philippines and the nearest known other population is in northern Borneo, some 550km to the south. Recommendations for conserving the population include that: (1) socioeconomic alternatives be developed to promote the conservation goal of reducing the incidence of dolphin entanglement in matang quatro gillnets; (2) gillnet free zones be established in core areas of dolphin distribution; (3) Irrawaddy dolphins be promoted as a flagship species of environmental health in the Sound; (4) a long-term programme be established to monitor the dolphin population; and (5) additional investigations be conducted to determine if Irrawaddy dolphins occur in other areas of the Philippines.

Authors:   The Foodservice Management Society Of Korea, Yun Sun-Mi , Park Deuk-Hee
Published: March 2023

A study was conducted using the raw data of the ‘2021 Food Consumption Behavior Survey’ to investigate the characteristics of each female and male consumer by comparing the selection factors when using delivery food for single-personal households. This study compared and analyzed the differences between female and male consumers using social network analysis. First, through density analysis and centrality analysis, a selection criterion network that is considered when choosing delivery food for a single-person housholds was established with female and male consumers, respectively. And the difference was compared using Bootstrap Paired Sample T-test. As a result of the analysis, it was confirmed that the delivery food selection factors of single-person households were different for male and female consumers. In addition, male consumers found that ‘delivery/food preparation speed’ was the most important selection factor, but female consumers used delivery food by considering various selection factors in a complex way.Based on the research results, we would like to present implications so that they can be used as practical data in establishing management strategies and policies for entrepreneurs and companies that want to enter the food delivery market in the future.

Authors: Lamprinidis Lampros
Published: March 2023

Purpose: The object of this paper is an overview of the European Model of Socially Responsible Public Procurement for the purpose of knowing the civil servants involved in the public contracts and the prospective contractors about them. Public buyers spend more than 16% of the EU’ GDP. By using the Public Procurement effectively by contracting authorities, one can have positive social impact (such as the reduction of criminal rate because of the employment of ex-offenders or immigrants) and contribute to sustainable development. Socially Responsible Public Procurement, in other words, take into account social considerations in public contracts in order to achieve positive social outcomes through the purchasing power of the Public Sector.

Methodology: Concise review of the most important Articles of Directive 2014/24/EU related to Socially Responsible Public Procurement in the European Union will be made.

Findings:  Presentation of the most important articles of Directive 2014/24/EU on Socially Responsible Public Procurement

Unique Contribution to Theory Practice and Policy:  For the first time, stakeholders in Socially Responsible Public Procurement will have a comprehensive overview of the institutional framework in place in the European Union to be able to develop relevant public policies (employment, social policy, etc.). This work hopes to become a reference point for both Social Economy Operators and Contracting Authorities, both to facilitate the access of the former to the EU public procurement market and to provide a basis for the development of initiatives to further improve this institutional framework.

Authors: Savina Anna A. , Feiginova Svetlana I. , Zemlyanova Elena V.
Published: March 2023

Introduction. The COVID-19 pandemic influenced the health status and mortality of population all over the world. The mortality rate in Moscow also increased significantly since the density of Moscow population is high and the city is very attractive for migrant workers. Objective. To determine the contribution of migrants died from the COVID-19 to the mortality in Moscow for 2019–2021. Materials and methods. In study, authors used the data on Moscow population and the real-time data on deceased persons by death causes according to the ICD-10 provided by the Moscow Healthcare Department.
Results. The average contribution of migrants to the total mortality in Moscow is 10% among women and 16% among men. As for the age composition, the most significant contribution is from the migrant children and working-age youth aged 20 to 30 in women (an average of 50%) and 35 in men (an average of 60%). These results are especially true for migrant workers. Diseases of the circulatory system, external causes and neoplasms were the leading death causes among migrants before the pandemic. Then, the COVID-19 became the third common cause in 2020 and the first one in 2021. As for the death cause, the migrants contributed most to the perinatal and maternal mortality as well as to the mortality from infectious diseases, mental disorders and external causes.
Conclusion. Cardiomyopathy and endocarditis, leading causes from the diseases of the circulatory system, often become the complications of infectious diseases, including imported infections. It is crucial to reimplement a rigorous record-keeping by citizenship and place of birth or residence, particularly within the databases on deceased population, in order to monitor the epidemiological situation and to make timely organizational decisions.

Published: March 2023

Background. Nutrition is one of the most important determinants for the population health. Increasing the population commitment to a healthy lifestyle, in particular healthy nutrition, is an important state task, which includes an integrated approach: educational policy, creation of an economic, legislative and material base. Monitoring is necessary to determine the necessary areas of work and evaluate their effectiveness.
Subject. Perceptions of Moscow population about capital about healthy eating and eating behavior. Objective. To identify the specifics of the Moscow population's perception of healthy eating and appropriate behavior, with comparison to the healthy eating norms. Methods. Authors used statistical data by Rosstat on the consumption of basic food products and telephone survey of the Moscow population, conducted by the Research Institute for Healthcare Organization and Medical Management of Moscow Healthcare Department (2021). 474 people were interviewed, representing the population by age and sex. Results. The majority of Muscovites (59%) consider healthy eating as abiding by nutritional principles. 22% of respondents told about the need to exclude/reduce certain foods and dishes (fatty, sweet, fried food) in their diet. 26% of respondents associate vegetables with a healthy diet, 17% named fruits, 7% mentioned meat. The study revealed insufficient consumption of 1) vegetables and melons is detected: 102.9 kg/year/person vs the recommended 140 kg/year/person; 2) fruits and berries: 80.6 kg/year/person vs the recommended 100 kg/year/person. In turn, the consumption of sugar and confectionery products is excessive: 22.1 kg/year/person vs the recommended 8 kg/year/person. Consumption of meat and processed meat is also excessive, mainly due to industrial meat products. The study correlated statistical and survey data and found a few intersecting points.
Conclusion. In general, the population has notions of a healthy diet, but it needs to be supplemented, adjusted and systematized. In particular, eating habits of specific foods prove the need to strengthen preventive work in this area.

The counselling profession plays a pivotal role and is often considered emotionally demanding. However, previously published studies on emotions at work have been limited in terms of research among counsellors. Hence, this study aims to explore (1) how counsellors perceive their profession, (2) how their work emotions come about when dealing with clients, (3) and what are the main job demands and resources of the counsellors. The current study employed qualitative research using a phenomenological research design. Individual in-depth semi-structured interviews with 44 registered professional counsellors in Malaysia were conducted to understand their experience of, and perceptions about, the counsellor’s job. Several themes developed based on the literature review, and discussions among the authors were made to see any disagreements regarding the selected themes. The team properly addressed any inconsistencies that arose. The first finding revealed that counsellors perceived their profession as a challenging occupation. As for the second finding, two themes were associated with the counsellors’ emotions at work: (1) positive and (2) negative emotions. Working conditions were the most recurring theme in the last finding of the study that influenced the job demands. In contrast, emotional support and professional growth were two job resources that helped reduce stress among counsellors.
Factors Associated with Contraceptive Use in Malaysia and Pakistan

Most developing countries launched the national family planning program in the 1960s/70s. However, some countries’ contraceptive prevalence rate (CPR) remains low or stagnated. Despite having a similar religious belief, the level of contraceptive use differed between Malaysia and Pakistan. This study examines the factors associated with contraceptive use in Malaysia and Pakistan. This study used secondary data from the 2014 Malaysian Population and Family Survey and the 2017–2018 Pakistan Demographic and Health Survey. A total of 5,175 Malaysian and 14,502 Pakistani currently married women aged 15–49 were included in this study. The dependent variable is current contraceptive use. The independent variables include women’s age, age at first marriage, place of residence, women’s educational level, employment status, and the number of living children. Crosstabulations show that urban, better-educated, and working women in Pakistan reported higher modern CPR than their rural, lesser-educated, and non-working counterparts; however, the opposite was observed in Malaysia. Multinomial logistic regression analysis reveals that rural women were less likely to practice modern and traditional methods than non-use in Pakistan. In Pakistan, the odds of practising modern and traditional methods than non-use were higher among women who attained at least primary education, while working women were more likely to practice modern contraceptive methods than non-use and traditional methods. However, women’s education and employment factors were insignificant in the multivariate context of the case of Malaysia. Enhancing women’s socio-economic status and reaching out to rural, uneducated, and jobless women are essential to improving contraceptive use, especially in Pakistan.
Um diálogo entre Hans Kelsen e Henrique Cláudio de Lima Vaz
Authors: Reis Patrícia
Published: March 2023

Neste artigo, gostaríamos de confrontar certas ideias defendidas por Hans Kelsen e por Henrique Cláudio de Lima Vaz. Percebemos que, na sua teoria, Kelsen defende uma separação entre Ética e Direito. Lima Vaz, por outro lado, propõe uma junção entre esses campos do saber. Diante dessas posições, nosso intuito é investigar se o pensamento destes dois autores é completamente antagônico ou se, em alguma perspectiva, suas concepções sobre o Direito podem convergir.
A tutela do embrião humano no cenário ítalo-brasileiro: um estudo comparatístico
Authors: Catalan Marcos Jorge , Ferraro Angelo Viglianisi
Published: March 2023

O avanço da técnica por sobre o delicado campo da reprodução humana assistida e a inegável possibilidade de manipulação de embriões alijados da proteção intrauterina emergem como as justificativas da elaboração de uma investigação científica que procura mapear como Brasil e Itália tutelam referida personagem. Sem adentrar nas discussões que tentam definir o status jurídico dos embriões, o artigo se dedica a identificar as regras abstratamente previstas em cada país e, ainda, como as intervenções havidas nas respectivas Cortes Constitucionais ampliaram ou restringiram as possibilidades legislativamente antecipadas sob a forma de regras ou princípios. O artigo foi moldado com amparo na imaginação jus-sociológica, tendo encontrado na revisão de literatura e na análise de julgados o método de pesquisa. A crítica metodológica permitiu o alinhavar de um texto que comprova haver mais pontos de proximidade que de distanciamento no que toca à tutela dos embriões pré-implantatórios e dos excedentários.

This brief summarizes findings of a case study of Bharatpur, Nepal, that examined ways to undertake inclusive urban development to reduce biological hazards and disaster risks. The authors apply a recently developed framework and, based on this, they recommend five policy changes: 1) Increase policy coherence and institutional coordination across levels and sectors of government. 2) Pay attention to the different impacts hazards have on different groups. 3) Develop capacity and allocate resources to help local government address risks for different groups. 4) Customize policies to address needs, particularly in peri-urban and rural areas engulfed by rapid urban growth. 5) Use community-engagement approaches to include and address issues raised by residents of marginalized communities.
A financial simulation for investment appraisal in solar panels at fast-food chains : a case study of McDonalds, South Africa
Authors:   , Abbana Sharanam Sharma
Published: March 2023

The sun is a significant source of inexhaustible free energy with the least adverse impact on the atmosphere. In order to overcome the adverse environmental effects and other issues connected with fossil fuels combustion, many nations have been compelled to investigate and develop environmentally-friendly options that are renewable in order to keep up with the growing demand for energy. This study was motivated by South Africa’s current electrical energy crisis and frequent load-shedding situations. Despite a global push towards renewable energy, South Africa presently relies on coal-fired power plants for more than 90% of its electrical energy. Currently, above-inflationary electrical energy tariffs are expected to increase. One of the renewable energy sources available is solar photovoltaic (PV) energy. The aim of this study was to financially simulate and appraise solar energy investment for McDonalds, an intensive fast-food restaurant energy consumer, to assess the feasibility of the investment. This study was quantitative in nature that simulated a census of 125 McDonalds DriveThru restaurants across South Africa. The data was derived from public domains such as a solar PV watts calculator from National Renewable Energy Laboratory (NREL) and solar system online commercial quotes from Treetops which is a solar system South African based installation company. Thereafter, the data was inputted in the study’s investment appraisement. The findings of the financial simulated investment appraisal prove to be lucrative for McDonalds South Africa to undertake the investment in solar energy. The investment is rewarding in the longer-term compared to the shorter-term considering the initial outlay. The simulation process and the investment appraisal in this study contributes to the knowledge base of the South African fast-food sector and can be adapted and used by businesses to evaluate the feasibility of a solar energy investment.

The article deals with the problems of technical renovation of the Kazakh theater stage. The relevance of the problem raised in the article is connected with the need for timely changes in the staging practice of theaters of the republic. These issues required a comparative and historical-cultural analysis of the problems of improving the technique of the stage and equipping the stage with equipment in the modern era. The global development of technology has forced many theater professionals to seriously think about the relationship between technology and art. After all, the technical equipment of the stage changed and developed along with the change in the tasks assigned to the theater by society. These problems arose in the theater in ancient times and accompanied the theater throughout its development. From this point of view, the question arises: is it necessary to look for new types of mechanical equipment, or has the theater reached the point where technology threatens art? In order to answer many questions put forward by time, it is necessary first of all to understand how stage technique developed and what role it played in the theater at different stages of its development. This requires a comparative analysis of the use of past and present technologies. It is also necessary to establish the boundaries of the use of technical means and the areas in which they are currently used.
