SISTEMAS DE PROTEÇÃO SOCIAL LATINO-AMERICANOS E RESPOSTAS À PANDEMIA DE COVID-19: Argentina, Brasil e México
Authors: Senna Mônica de Castro Maia , Ferreira Aline Souto Maior , Baldo Valentina Sofia Suarez
Published: September 2021

O artigo analisa como sistemas de proteção social na América Latina têm respondido à grave situação social decorrente da pandemia de COVID-19. Pautado em estudo exploratório, o artigo toma como foco as experiências da Argentina, Brasil e México. A perspectiva de análise considera que as respostas produzidas por esses três casos às demandas sociais postas pela pandemia decorrem da interseção entre o legado prévio e estrutura institucional dos sistemas de proteção social existentes em cada país, a orientação política dos governos em exercício e a dinâmica social e política diante do contexto da crise sanitária. Verifica que nos três países, a despeito de medidas protetivas de maior ou menor abrangência e magnitude, que reforçam a proteção social existente ou introduzem novos mecanismos – todos eles temporários – a crise social própria às formações sociais latino-americanas se agravou.LATIN AMERICAN SOCIAL PROTECTION SYSTEMS AND RESPONSES TO THE COVID-19 PANDEMIC: Argentina, Brazil and MexicoAbstractThe article analyses how social protection systems in Latina America have responded to the serious social situation caused by the COVID-19 pandemic. Guided by an exploratory study, the paper focuses on the experiences of Argentina, Brazil and Mexico. The analysis considers that the responses produced by the three cases results from the intersection between the institutional structure’s previous legacy of the social protection systems existing in each country, the political orientation of the governments in exercise and the social and political dynamics in the sanitary crisis context. It seems that, despite protective measures of greater or lesser scope and magnitude, which either reinforce the existing social protections or introduce new mechanisms – all of them temporary – the social crisis specific to Latin American social formations has worsened in the countries studied.Keywords: Social protection.

Chemical Debridement in Burns: A Pragmatic Alternative When Surgical Debridement Is Not Available
Authors: Laher Naadiyah , Moore Rachel
Published: September 2021

BACKGROUND: Up until the late 1960s, full thickness burns were traditionally managed with topical agents until the eschar separated and only then would a skin graft be considered. Thus, complete wound healing could take up to 5 weeks, with resultant lengthy hospital stay and a significant loss of physical function. A paradigm shift occurred in the 1970s with a move to early excision and grafting of the burn wound.(1) In South Africa, many district hospitals admit patients with full thickness burn wounds but do not have the facilities to provide skin grafting or tangential excision. We describe a case of the successful use of enzymatic debridement, meticulous wound care and primary healing of a full thickness burn wound in a district hospital with no surgical capabilities to manage burns as a pragmatic alternative to the well-established, gold standard of surgical excision and grafting.(1)

The Family Environment and Its Relation to Health and Well-Being Among Sexual and Gender Minority Youth
Authors: Rathus Taylor L. , Watson Ryan J.
Published: September 2021

We examined youth-reported family environments using multiple indicators (parent education, participants' first language spoken, and parent immigration status) to consider the family environment and its links to youth health and well-being. To do so, we utilized cluster analysis methodology to identify potential groupings of family environments among a national sample of 14,578 sexual and gender minority (SGM) youth from the LGBTQ National Teen Survey, collected in 2017. Three distinct clusters of SGM youth emerged, labeled “College-educated, U.S.-born parents,” “High school-educated, U.S.-born parents,” and “College-educated, immigrant parents.” “A series of one-way between-subjects ANCOVAs revealed each cluster significantly differed from each other on health and family outcomes, indicating that parent immigration status, parent education, and youth first spoken language are uniquely and collectively imperative for SGM youths' health and well-being.” Of note, despite reporting parents with the highest level of post-high school education, SGM youth in the “College-educated, immigrant parents” cluster reported the lowest levels of parental acceptance and the lowest levels of outness in comparison to the youth in the other two clusters. In light of these results, we review the importance of the need for more nuanced ways of defining the family context among vulnerable youth—in particular for SGM youth. Given that much of the research to date defines the family environment by single indicators (e.g., parent education), we review the importance of broadening our conceptualization and measurement of the “family environment.”
Affordable social infrastructure vs public-private partnership
Authors: Maximov Vitaly
Published: September 2021

The article is devoted to the problems of sustainable development of social infrastructure and social services, which are beyond the effective demand of large cities, cannot develop according to market laws, and provide the necessary level of infrastructure fullness. Despite 45.9% of private companies in the social sectors, the vast majority of real estate objects continue to be owned by the state, forming the need to find economic mechanisms for the development of state social infrastructure, outside of limited budget opportunities. The possibility of attracting private investment in new construction and reconstruction without alienating the ownership right to it makes public-private partnership (PPP) and the economic mechanism based on it have no alternative. However, its practical application suffers from asociality, leading to the appearance of state-owned facilities where private investors conduct exclusively commercial activities. The apparent budget savings lead the state, judicial and supervisory authorities in such territories to a strategic failure, reducing the number of state facilities operating at state prices, ignoring the requests of the population for affordable social infrastructure, increasing social tension in society. This work is aimed at studying the irrational behavior of private investors, the stability of which is provided by the PPP mechanism, where the state determines the necessary level of the sociality of infrastructure objects that best corresponds to the existing stratification of residents of a certain territory through competitive procedures and essential conditions of the future project. It is necessary to continue research on improving federal legislation, whose social neutrality leads to conflicting expectations of the parties from PPP, adding sensitivity to a wide range of risks, repelling private investment and investors, limiting infrastructure development only to budget opportunities. The development of an economic mechanism that ensures finding a balance of accessibility and market rationality of social facilities is not an easy task, which has many solutions taking into account the characteristics of a particular territory and its population

Published: September 2021

Formation of financial institutions in society, development of the financial services market and effective financial relations is impossible without formation of a developed financial and economic culture. Today, such a financial and economic system can be viable, which will take into account the social aspects of society's life, its factors and prerequisites, as well as values that really contribute to the survival, preservation and development of humanity, strengthening its unity, expanding its potential. Taking this into account, formation of a financial and economic culture based on universal principles in the context of new trends in the socio-cultural development of the country is one of the most acute modern problems. Each financial and economic system corresponds to a special basic model of financial and economic culture and values, which is manifested in national specific forms in each country. There are no «good» and « bad» cultures, but there are functional or dysfunctional cultures relative to the financial and economic system. According to the criterion of the essence, financial and economic culture is a type of social culture of society that provides for the needs of multidimensional human activity in specialized types of financial and economic activity. In modern society, there is a tendency to raising the cultural level of production. It finds expression in use of the latest technology and technological processes, advanced methods of labor organization, progressive forms of management and planning, scientific achievements. The direction of this development is determined, on the one hand, by the opportunities contained in the set of conditions that define the boundaries of economic culture, on the other hand, by the degree and ways of realizing these opportunities in the conditions of changes in the innovative economy. In view of this, analysis of patterns of financial and economic culture and creation of mechanisms for influencing them is an important managerial task, no less important than creation of an innovative economy and construction of a rule-of-law state. Based on the study of factors affecting the formation of the financial and economic culture of Russians, the authors developed classification, which includes the factors of the Russian cultural archetype; of the socio-economic context; of vertical and horizontal socialization.
Quality of life and human potential in the concepts of sustainable and human development (Part 2)
Authors: Fedotov Artem
Published: September 2021

Human potential and quality of life are the most important socio-economic categories. On the one hand, development of society is connected with improvement of the quality of life of people and realization of their human potential. On the other hand, it is human potential that is currently the main driving force contributing to economic growth, scientific and technological progress and cultural development of the country. Despite this, there is still no clear definition and unified measurement system for these categories. Abroad, there is no concept of human potential in general, although many concepts appeal to this very category. This review article attempts to define these complex social categories and clearly distinguish between them. In the course of the work, the chronology of development of these concepts, their evolution from related concepts and interpretation by modern concepts were analyzed. There were shown the fundamental differences between human potential and quality of life lying in different research objects. If quality of life mainly reflects external conditions of life, then human potential has as an object of study qualitative characteristics of population and therefore can be called quality of population by analogy with the definition of quality of life. The author also gave analysis of two modern concepts of sustainable and human development, identified their main principles, goals and objectives, and compared them with each other. As a result, it was concluded that these two concepts are almost identical and interchangeable. Besides, both of them are concepts of improving the quality of life, their main goal is to create favorable external conditions in which a person can freely develop and realize his aspirations and needs.

Published: September 2021

L’étude a eu pour objectif d’évaluer deux protocoles de synchronisation des chaleurs à base de prostaglandine F2α (alfaprostol 2 mg), l’un court à injection unique et insémination artificielle (IA) sur chaleurs observées, l’autre long à double injection à 11 jours d’intervalle et IA à temps fixe 80 heures après la seconde injection. Elle a porté sur 72 vaches et 12 génisses de race Goudali, toutes cyclées. Les semences utilisées ont été celles des taureaux Bruns Suisses, Aubracs et Gascons. Le taux d’induction des chaleurs a été de 100 %, avec un délai de 2 à 11 jours postinjection pour la venue des chaleurs en protocole court. Après un minimum de 60 jours post-IA, une palpation transrectale a été effectuée, ainsi qu’un suivi des gravidités jusqu’aux vêlages. Les taux de gravidité, d’avortement et de vêlage ont été respectivement de 17,8 %, 13,3 % et 15,4, soit respectivement pour les protocoles court et long 30,8 %, 16,6 % et 25,6 %, et 6,7 %, 0 % et 6,6 % (p < 0,05). La durée moyenne de gravidité a été de 290 ± 4,5 jours, soit respectivement pour les protocoles court et long 290 ± 4,5 jours et 289,7 ± 5,8 jours (p = 0,181). Le poids moyen des veaux à la naissance a été de 22,9 ±1,4 kg, soit respectivement pour les protocoles court et long 22,9 ± 1,6 kg et 23,0 ± 1,0 kg (p = 0,319). La sex-ratio (% de mâles par rapport à la population totale) a été de 69,2 % (p = 0,6). Les animaux présentant une durée post-partum entre 5 et 10 mois, dont l’IA avait été pratiquée dans le corps de l’utérus et entre 16 et 17 heures après la détection des chaleurs, ont présenté une meilleure fertilité (p < 0,05).

Published: September 2021

Abstract Background : At the beginning of a pregnancy the mother experiences various processes of transition or adaptation regarding changes in herself, so that she really needs support from her environment. Lack of social support can worsen the physiological complaints of pregnant women including Nausea and Vomiting in Pregnancy (NVP). Complaints of nausea and vomiting can affect the mother in carrying out daily activities, affect the mother's social situation with the environment and cause stress. Therefore, it is important to research the relationship between social support and the degree of nausea and vomiting in first and second-trimester pregnant women. Method : This research method is observational analytic with cross sectional research design. Sampling used the total sampling method with the criteria of pregnant women who had complaints of nausea and vomiting. Collecting data using primary data using a 24-hour PUQE questionnaire that measures the duration and frequency of nausea and vomiting and the MSPSS questionnaire measuring social support. The data collected were analyzed using the Spearman test (p<0.15). Results : Out of 47 respondents, 34 pregnant women (72.3%) received high social support. Besides that, 24 out of 47 respondents (51.1%) experienced moderate degree of NVP. In this study, there were no respondents who experienced severe degree of NVP. Spearman test analysis results obtained p= 0.833 or p>0.15. Conclusion : There is no relationship between social support with NVP in first and second trimester of pregnancy.

In March 2020, several mass gathering events were related to the Falles festival in Borriana (Spain), resulting in a 536 laboratory-confirmed COVID-19 cases outbreak among participants. Our objective was to estimate anti-SARS-CoV-2 antibodies persistence six months after and factors associated with antibody response. A prospective population-based cohort study was carried out by the Public Health Center of Castellon and the Emergency and Clinical Analysis and Microbiology Services of Hospital de la Plana in Vila-real. In October 2020, sero-epidemiologic study to estimate the persistence of anti-SARS-CoV-2 antibodies by a electrochemiluminescence immunoassay (ECLIA) was implemented. We enrolled 484 (90.2%) of the 536 members of the initial outbreak cohort and detected persistent antibodies in 479 (99%) without re-infection episodes. Five participants had a negative antibody test. Factors associated with a negative result were a lower body mass index (BMI), and less contact with other COVID-19 cases. Among the 469 participants with two ECLIA tests, 96 (20.5%) had an increase of antibodies and 373 (79.5%) a decline. Increased antibodies were associated with older age, higher BMI, more severe illness, and low current smokers. After a COVID-19 infection, a high proportion of cases maintained detectable anti-SARS-CoV-2 antibodies.
Changes in Risk in Medium Business Plants Following Revision of the Korean Chemical Accident Prevention System, Focusing on Plating and Paint Manufacturing Industries

Published: September 2021

: Chemical accidents can occur anywhere. The need for chemical management in Korea was realized following the 2012 Gumi hydrofluoric acid accident in 2012. The Chemicals Control Act was enacted in 2015. This system evaluates the risks (high, medium, low) and consequent safety management at all plants that handle hazardous chemical substances. However, the system was criticized as excessive when most plants were designated high-risk without considering their size. Thus, laboratories and hospitals handling very small quantities were subject to regulation. Accordingly, in 2021 Korea revised the system to include off-site consequence analyses and a Korean-style risk analysis. Plants handling very small quantities, such as laboratories and hospitals, were exempt from regulation. In this study, plating and paint manufacturing companies, which were classified as high-risk in the previous system, even though they were medium-size business plants, were re-evaluated as low-risk plants. In the Korean-style risk analysis, it is possible to see at a glance what is lacking in the plants, such as cooperation between local residents and local governments and the construction of safety facilities according to the type of accident scenario. The revised system is a reasonable regulation for medium business plants.
A Cloud Computing-Based Modified Symbiotic Organisms Search Algorithm for Ecosystem Sustainability
Authors: Zubair Ajoze Abdulraheem , Razak Shukor Bin Abd , Ngadi Md. Asri Bin
Published: September 2021

The search algorithm based on symbiotic organisms’ interactions is a relatively recent bio-inspired algorithm of the swarm intelligence field for solving numerical optimization problems. It is meant to optimize applications based on the simulation of the symbiotic relationship among the distinct species in the ecosystem. The modified SOS algorithm is developed to solve independent task scheduling problems. This paper proposes a modified symbiotic organisms search based scheduling algorithm for efficient mapping of heterogeneous tasks to access cloud resources of different capacities. The significant contribution of this technique is the simplified representation of the algorithm's mutualism process, which uses equity as a measure of relationship characteristics or efficiency of species in the current ecosystem to move to the next generation. These relational characteristics are achieved by replacing the original mutual vector, which uses an arithmetic mean to measure the mutual characteristics with a geometric mean that enhances the survival advantage of two distinct species. The modified symbiotic organisms search algorithm (G_SOS) aimed to minimize the task execution time (Makespan), response, degree of imbalance and cost and improve the convergence speed for an optimal solution in an IaaS cloud. The performances of the proposed technique have been evaluated using a Cladism toolkit simulator, and the solutions are found to be better than the existing standard (SOS) technique and PSO.

Published: September 2021

Medical Device Design process carries a high responsibility when defining the characteristics of the object for its correct interaction with users. This study presents a proposal for the improvement of the medical device design processes, in order to increase user acceptance, considering two key factors: the hierarchy of users and the relationship with the patient's health status. The goal of the study seeks to address this research gap and raise design factors with practical suggestions for the design of new medical devices. The results obtained will help medical device designers in the development stage to make more informed decisions about the functions and features required in the final product; As well, in the design process didactics, demonstrating the importance of the correct execution of the process, and how the factors considered can generate an impact on the final product. An experiment was carried out with Forty design engineering students, who designed birthing beds, with two design processes, the traditional product design process, and the new design process based on hierarchies (proposed in this study). The results showed that there is a significant increase in user acceptance with the new birthing bed that was developed with the hierarchical based design process.
Ramsey’s Theory Meets The Human Brain Connectome
Authors: Tozzi Arturo
Published: September 2021

Ramsey’s theory (RAM) from combinatorics and network theory goes looking for regularities and repeated patterns inside structures equipped with nodes and edges. RAM represents the outcome of a dual methodological commitment: by one side a top-down approach evaluates the possible arrangement of specific subgraphs when the number of graph’s vertices is already known, by another side a bottom-up approach calculates the possible number of graph’s vertices when the arrangement of specific subgraphs is already known. Since natural neural networks are often represented in terms of graphs, we suggest to utilize RAM for the analytical and computational assessment of a peculiar structure supplied with neuronal vertices and axonal edges, i.e., the human brain connectome. We discuss how a RAM approach in neuroscientific issues might be able to locate and trace unexplored motifs shared between different cortical and subcortical subareas. Furthermore, we will describe how notable RAM outcomes, such as the Ramsey’s theorem and the Ramsey’s number, could contribute to uncover still unknown anatomical connexions endowed in neuronal networks and unexpected functional interactions among grey zones of the human brain.
Ensuring Sustainability of a Mobile Legacy Network by Improving Network KPIs using Six Sigma DMAIC Framework with AHP based Analysis

Published: September 2021

Call set up success rate (CSSR) in a mobile network is an important quality parameter, which directly influences overall key performance indicators (KPIs) of the network service providers. Network KPIs especially the CSSR is the fraction of the attempts to make a call that result in a successful connection to the dialled number. Nevertheless, all call attempts do not end with a connection to the dialled number. In this research, six sigma methodology is applied to improve the call quality of a legacy mobile network and subsequently to boost comprehensive CSSR of a telecom service provider. This research elucidates an empirical study of improving overall CSSR by employing DMAIC methodology consisting of five stages, e.g. Define, Measure, Analysis, Improve and Control. In addition, analytic hierarchy process (AHP) technique is used for determining the vital causes out of all the identified network parameters affecting overall CSSR. Furthermore, the identified vital parameters are being upgraded in order to improve the overall CSSR and finally the system achieved a higher CSSR.
RECOGNITION OF DISCHARGES THAT ARE ACCOMPANIED BY LOW-TEMPERATURE OVERHEATING BASED ON THE ANALYSIS OF GASES DISSOLVED IN THE OIL OF HIGH-VOLTAGE TRANSFORMERS
Authors: Shutenko Oleg , Kulyk Oleksii
Published: September 2021

Based on the analysis of test results for 135 high-voltage transformers, ranges of gas percentage, gas ratio values were obtained and nomograms for 10 types of combined defects were made, representing discharges with different intensity which are accompanied by overheating with temperature of 150-300°C. It has been established that in transformers with discharges accompanied by low-temperature overheating the values of CH4/H2, C2H2/CH4, C2H2/C2H6 and C2H2/C2H4 ratios determine the discharge energy, in accordance with the norms regulated by the most known standards, the C2H4/C2H6 ratio varies slightly depending on the hot spot temperature and the C2H6/CH4>1 ratio value. Dynamics of defects nomograms changing in the process of their development is analyzed. It is stated by the analysis results that in majority of cases the primary defect is discharges with different intensity, which are accompanied by low-temperature overheating. Overheating occurs in the process of discharge development. The analysis of recognition reliability of discharges with different intensity which are accompanied by 150-300°C overheating was made, using norms and criteria regulated by the most known standards and methods. The results of the analysis show that the most reliable recognition of the defects analyzed is provided to a large extent by the graphical methods, namely the ETRA square and the Duval triangle. The results obtained will significantly increase the recognition reliability of combined defects based on the results of the dissolved gas analysis in the oil.

Published: September 2021

The Manhattan Engineer District previously used the 191-acre Niagara Falls Storage Site (NFSS) in Niagara County, New York, to store radioactive residues and wastes from uranium (U) ore processing. At present, management practices will determine whether enhanced evapotranspiration rates produced by hybridized shrub willow cuttings planted in 2016 will affect groundwater hydrology. Two shrub willow varieties were planted in an approximately one-half acre area to examine growth performance along a U impacted sanitary sewer line. Additionally, control plots will compare the effectiveness of shrub willows to unplanted areas. Observations of the planted area after 18 months showed success of shrub willow growth with increasing biomass. Chemical analysis from tree tissue samples of the field study showed no significant uptake of U or thorium (Th) to date. A greenhouse study conducted in parallel to the field study tested the willows under controlled greenhouse conditions and evaluated their ability to grow and accumulate contaminants under controlled conditions. Results from the greenhouse study demonstrated that U accumulation was minimal. Thus, this study demonstrates that the shrub willows are not accumulators of U or Th, an advantageous characteristic that implies stabilized contaminants in the soil and no translocation of U into the aboveground biomass.

A avaliação foi composta por dois cenários: o cenário referência, com uso contínuo do medicamento, e o cenário comparador, com a interrupção do tratamento medicamentoso. Ambos os cenários consideraram as tecnologias disponíveis no período de 2015 a 2019. A análise de sensibilidade propôs variações nos cenários com a finalidade de avaliar a robustez do modelo. Além disso, uma extrapolação para nível nacional foi realizada, utilizando dados epidemiológicos para a obtenção do número de pacientes. Resultados: Foram selecionados 268 pacientes que iniciaram o tratamento até 2012. Desses, 65 foram elegíveis à descontinuação. A análise econômica mostrou uma economia de R$670.558,10 no primeiro ano, uma economia acumulada em cinco anos de R$3.665.355,98 e de R$66.517.232,80 no contexto institucional e nacional, respectivamente. A análise de sensibilidade foi favorável em todos os cenários propostos. Conclusões: A descontinuidade do tratamento da LMC mostrou-se, economicamente, uma importante oportunidade sob a perspectiva do sistema de saúde em flexibilizar novos investimentos tecnológicos e/ou ampliação de acesso, além da melhoria na qualidade de vida do paciente.

Objetivos: Este estudo teve como objetivo avaliar desfechos clínico-econômicos associados à vacina contra influenza quadrivalente baseada em células (QIVc) versus a vacina trivalente atualmente utilizada (TIVe) para prevenção sazonal de influenza no Programa Nacional de Imunizações (PNI) brasileiro. Métodos: Um modelo estático de árvore de decisão foi usado. Considerou-se um total de 54.071.642 indivíduos vacinados em 2019; a circulação de influenza por subtipo foi baseada em dados de vigilância epidemiológica. A efetividade da vacina (EV) TIVe foi extraída de metanálises publicadas; já a EV relativa da QIVc foi retirada de um estudo observacional retrospectivo. A incompatibilidade antigênica da vacina com vírus circulantes foi baseada em fontes retrospectivas internacionais. O uso de recursos baseou-se em estudos do mundo real. Custos unitários foram retirados de tabelas-padrão publicados em 2019 em reais (BRL). Resultados: Substituir a TIVe pela QIVc pode evitar, anualmente, casos sintomáticos (452.065) e reduzir visitas ambulatoriais (118.735), hospitalizações (15.466), mortes (2.753), custos médicos (-BRL 46.677.357) e custos indiretos (-BRL 59.962.135). O número anual de anos de vida ajustados por qualidade de vida (QALYs) pode aumentar em 96.129. Resultados de base a partir da perspectiva do pagador mostram uma razão de custo-efetividade incremental (RCEI) de BRL 17.293/QALY e, da perspectiva da sociedade, o RCEI obtido foi de um ganho de BRL 16.669/QALY. Usando o Produto Interno Bruto (PIB) brasileiro como um limiar (BRL 34.533/ QALY), trocar a TIVe pela QIVc no PNI pode ser uma estratégia altamente custo-efetiva. Conclusões: O uso da QIVc pelo PNI tem potencial para ser altamente custo-efetivo tanto da perspectiva do pagador quanto da sociedade.

Objetivo: Diante da problemática da COVID-19, o município de Fortaleza – CE se destaca pela alta taxa de letalidade verificada até o momento. Para inibir a propagação da doença, os gestores implementaram medidas restritivas para a sua contenção, para, com isso, diminuir as chances de sobrecarregar os leitos hospitalares disponíveis para o tratamento. Nesse sentido, o presente artigo tem como objetivo analisar a efetividade das políticas de isolamento social no município de Fortaleza-CE. Métodos: Para tanto, foi utilizado, como suporte empírico, o modelo SIR (Susceptible, Infectious, or Recovered) proposto por Kermack e McKendrick (1927), para doenças de infecção primária. Os dados para o estudo foram coletados em Cota (2020), no período de 16/03/2020 a 31/05/2020. Resultados: Os resultados mostram que, com o início do isolamento social, a taxa média de transmissão passou de 0,4427 para 0,0945, uma redução de cerca de -75,59%. Após a implementação do lockdown, a taxa média foi alterada para 0,0349, o que representa uma redução de -88,69% na taxa de transmissão do vírus. Conclusão: Concluiu-se, portanto, que as implementações de políticas restritivas reduziram a taxa de transmissão e o número de casos da doença.

Although being widely used as an artificial lift method for heavy oil field developments, Electrical Submersible Pump (ESP) performance in high viscous applications is not fully understood. In order to improve knowledge of pump behavior under such conditions, Equinor has developed stage qualification tests as part of the technical requirements for deploying ESPs in Peregrino Field located offshore Brazil and has funded a series of research efforts to better design and operate the system more efficiently.

Qualification tests were made mandatory for every stage type prior to field deployment in Peregrino. It is known that the affinity laws don´t hold true for high viscosity applications. Therefore, extensive qualification tests are required to provide actual stage performance in high viscous applications. Test results are used to optimize ESP system design for each well selecting the most efficient stage type considering specific well application challenges. In addition, the actual pump performance improves accuracy in production allocation algorithms. A better understanding of ESP behavior in viscous fluid application helps improving oil production and allows ESP operation with higher efficiency, increasing system run life.

Shear forces inside ESP stages generate emulsion that compromises ESP performance. Lab tests in controlled environments have helped Equinor to gather valuable information about emulsion formation and evaluate ESP performance in conditions similar to field application. Equinor has funded studies to better understand two-phase flow (oil-water) which allowed visualization and investigation of oil drops dynamics inside the impeller. In addition, experimental procedures were proposed to investigate the effective viscosity of emulsion at pump discharge and the phase inversion hysteresis in the transition water-oil and oil-water emulsion.

In addition to qualification tests and research performed to better understand system behavior, Equinor has developed and improved procedures to operate ESP systems in high viscous applications with emulsion production during 10 years of operation in Peregrino field. Such conditions also impose challenges to ESP system reliability. Over the years, Equinor has peformed failure analysis to enhance ESP system robustness which, combined with upper completion design, have improved system operation and reliability decreasing operating costs in Peregrino field.

Toxic cyanobacteria blooms are a potential threat to global aquatic ecosystems and human health. Microcystin-leucine-arginine (MC-LR) is the most toxic variant of microcystins (MCs), and exposure to MCs can damage the male reproductive system.Two electronic databases were searched for controlled studies of rodents and fishes published before September 2020. Effect sizes were calculated for eight main reproductive parameters, including sperm count, sperm motility, sperm morphology, serum testosterone, testis weight, serum follicle stimulating hormone (FSH), serum luteinising hormone (LH) and serum estradiol. Nine meta-analyses of individual parameters were conducted using R version 4.0.2. Fifteen studies were included in the meta-analysis. In the studies of rodents, exposure to MC-LR by intraperitoneal injection or intragastric administration yielded statistically significant effects on sperm count (standardised mean difference (SMD) = -1.7426 (95% CI: -2.2098 to -1.2754)), abnormal sperm rate (SMD = 1.6714 (95% CI: 0.9702 to 2.3726)), sperm motility (SMD = -2.8822 (95% CI: -3.9811 to -1.7834)), testis weight (SMD = -2.8822 (95% CI: -3.9811 to -1.7834)) and serum FSH (SMD = 0.4707 (95% CI: 0.0659 to 0.8756)). In fish studies, the changes in serum testosterone (SMD = 0.5521 (95% CI: 0.1652; 0.9391)) and estradiol (SMD = 0.6398 (95% CI: 0.1896 to 1.0900)) concentrations are considered to be statistically significant. Dose–response analysis reflected the dynamic changes of male reproductive function caused by MC. Short-term exposure to MC-LR can affect the function of the male reproductive system in rodents and fish. Elevated dosage or extended exposure time may worsen the damage. Human-related research on MC-LR exposure is very necessary to protect health and the water environment.
