Authors: Amyaga E.N. , Isaev S.P.
Published: May 2021

At present, it is especially acute to study valuable forest species at the genetic level in order to ensure their safety, species identification and the origin of wood control. Larch (Larix) is one of the ecologically and economically important conifers in our country. Preservation and study of the forest plant species genetic diversity anywhere, including the Jewish Autonomous Region (EAO), is one of the fundamental challenges of modern botany, ecology, genetics and dendrology. In the article, the author analyzes samples of larch stand needles collected in the Jewish Autonomous Region. Using the necessary loci, selected by means of the genetic method, the author analyzed features of the Larix gmelinii and Larix sibirica species [4] No less urgent is the problem of plant damage by phytopathogens. A phytopathogen is a causative agent of plant disease that releases biologically active substances that have a detrimental effect on metabolism, affecting the root system, disrupting the function of chloroplasts, growth processes, and the supply of nutrients. Violation of metabolism in plant cells and organs, resulted in their productivity decrease or complete death, leads to the disruption of populations’ integrity and causes enormous harm to both agricultural crops and forest-forming species. This work shows the results of analysis of the larch plantations phytosanitary state and the percentage of healthy and affected plantations in the regions. The comprehensive laboratory analysis has shown that the laboratory methods successfully complement each other. It is possible to give a complete and correct description of taxonomic and biological characteristics of a phytopathogen using simultaneously several laboratory techniques for its identification. Ultimately, it should be of help in the development of methods for combating pathogens.

Published: May 2021

Relevance. According to US scientists, the percentage of people who do not know about their positive status is 20% of all people living with HIV. Moreover, this group provides 49% of new infections. Therefore, it can be assumed that information about HIV status has a significant epidemiological effect. Aim. To assess the change in risk behavior of HIV-infected persons after informing about the diagnosis and the frequency of occurrence of nonspecific symptoms of HIV infection. Materials and methods. For information on changing the behavior profile was developed, consisting of three sections. The first and third sections are aimed at elucidating the characteristics of sexual and drug behavior from the moment of probable infection to the moment of diagnosis, in comparison with the time period from the moment of reporting the diagnosis to the present. The second section of questions is aimed at determining the frequency of occurrence of nonspecific symptoms of early HIV infection. In the survey agreed to participate in 79 HIV-infected patients. The reliability of the results obtained was determined using the Wilcoxon Sign Test. Results. The message of the diagnosis of HIV infection contributed to the desire to abandon the systematic use of intravenous drugs. The proportion of people who denied drug use increased from 13 to 65% (p < 0.05). The number of people infected intensively (30 and more doses / month) using drugs has more than halved – from 38 to 17% (p < 0.05). The number of people denying drug use in groups increased from 10 to 45% (p < 0.05). From 55 to 12% (p < 0.05), the proportion of people who pass their syringe (needle) to another person to inject drugs has decreased. The number of persons who noted the presence of more than 5 partners per year after diagnosis decreased three times (p < 0.05). Only 23% of the respondents did not present any complaints in the period preceding the detection of HIV infection. Symptoms of acute respiratory disease marked 48%, 37% had fever, and other non-specific clinical manifestations of HIV infection. Conclusion. Communicating a positive HIV status to a patient reduces the likelihood of HIV transmission by drugs by 3–4 times and sexually by 2–3 times by changing risky behavior. Nonspecific symptoms of an acute viral disease before the detection of HIV infection were recorded in 48% of cases.

Published: May 2021

Relevance. The socio-economic significance of mumps is determined by complications after a previous infection, affecting reproductive function, what entails economic and demographic losses. An important problem today remains the fact that despite high coverage with preventive vaccinations outbreaks of mumps are recorded among children and young adults. Aim. Analyze the epidemic situation with epidemic parotitis in the world according to various literary sources and evaluate measures to control and combat this infection. Conclusions. Outbreaks of mumps have been reported among religious and ethnic groups. Outbreaks were often recorded in organized student and military groups, mainly among persons twice vaccinated. The most affected by the mumps virus were adolescents and young adults, mostly males. Several researchers have shown the possibility of using a third dose of MMR vaccine to control an outbreak, but its short-term effect does not provide conclusive evidence for rethinking two-dose mumps immunization.

Female students face various problems in the undergraduate computer science environment. In this paper we investigate undergraduate computer science students' perceptions of discrimination, harassment, drop out intention, gender devaluation, sense of belonging, gender stereotype, and self-efficacy. It also collects information about unpleasant facts that happened to students. A questionnaire was applied to two hundred and fifty students from undergraduate computer science courses from more than twenty universities in Brazil. Data from the questionnaire were analyzed using statistical methods. A comparison between men and women experiences is provided. In addition, we examine correlations between issues reported by the female students and their intentions to leave university. The results show that the majority of students in both sexes have a low sense of belonging and also that men bear some of the problems. Nevertheless, women suffer more from discrimination and gender stereotype than men.

Stranding is the event in which a marine animal comes ashore after death or comes and is unable to return to the sea, which may occur due to natural, spatial tendencies and anthropic actions. It occurs in many countries, several of which have created formal programs to monitor. Mammals are at the top of the food chain, suffering more from changes in the environment, which is why they indicate the quality of the ecosystem. In the southern region of Brazil, inventories of marine mammal biodiversity emerged in the 1980s. Registering stranded data makes it possible to discover important information about marine animals and the oceans. This work aimed to collect information to identify the composition and abundance of strandings of marine mammals. The studied area is located on the southern coast of Santa Catarina, between the municipality of Jaguaruna and Passo de Torres. Data refer to collections made by the Zoology Museum Morgana Cirimbelli Gaidzinski , from the University of the Extreme South of Santa Catarina (UNESC), during the period from 2003 to 2016, through third-party activations and systematic monthly monitoring. The stranding frequency in this period was 344 mammals, belonging to 15 species, 10 genera, six families and two different orders. The occurrence of rare and unpublished animals was observed, such as Balaenoptera physalus, Kogia breviceps and Arctocephalus gazela.
Aluminum Slag Separation Process Analysis Through a Vibratory Machine in the Foundry Process
Authors: Oliveira Valcimar de Souza , Nascimento Denise Andrade do , Castro Luís Smith de Oliveira , Souza Thales Ruano Barros de , Serrão Luan da Silva
Published: May 2021

A The aluminum smelting industry has some challenges, due to the characteristics of the alloy that cause reactions that should be controlled. During the foundry process, the alloy is oxidized by contact of the molten aluminum with the ambient air. Oxide films forming on the surface of the molten metal must be removed during the cleaning of the furnaces in order to avoid contamination of the alloy to be used in the production of parts. Analyzing the melting process of a metallurgy at the industrial complex in Manaus, we saw that during the cleaning of the furnaces a metal tool is used to remove the slag, which brings with it a high level of aluminum brought about by the mechanical drag of the tool. As the company in question does not have resources to recover the metal aluminum contained in the slag, it is destined for the other institution which carried out the processing through the process of refusion of the slag and extraction of aluminum. The high level of losses in the process due to the discarding of slag generates considerable financial damage to the institution, reflected directly in the cost of manufacturing the products. In this way, the aim of the present work was to develop equipment for the extraction of the metal aluminum contained in the slag and consequently to reduce the losses in the process. The design of the equipment was chosen through a product development methodology, which made it possible to define the design specification, which can count on a container for the receipt and separation of the slag by means of the vibration brought on by motorvibrators installed at its ends, followed by a slingshot drawer responsible for the storage of the metal after the solidification and support/translate cars of the containers.

Published: May 2021

During the COVID-19, schools were faced with changes in organizational culture under the digital education model. It is a new challenge facing higher education universities to promote cultural competitiveness, enhancing the confidence of educators in organizational culture, and communicating the cultural atmosphere to educators through digital technology. This concept paper mainly emphasizes the introduction of Digital Arts experience into organizational culture, thereby enhancing the appeal of the university organizational culture. This requires the university to combine both ideology and technology, highly advocating the organization's core concept through the global digital trend during the pandemic. This concept paper provides a new perspective of change for constructing organizational culture in universities facing education and digital challenges during the pandemic. The Digital Arts experience will be an essential part of the global university organization culture after COVID-19.
The Need for Context-specificity in Global Educational Policy Transfer by Non-state Actors
Authors: OLANREWAJU GIDEON SEUN , Omotosho Abiodun Yetunde , Falajiki Olajide Charles , Osama Godwin
Published: May 2021

The revitalised role of non-state actors such as non-profit organisations and education reform movements in educational provision and delivery has contributed to the global circulation of uninformed transnational adaptation of ideas and practices around educational change. In adapting models in one place for emulation in another place, educational non-profits often lose sight of the local realities, thereby decontextualizing cultural differences and normalizing the language of generalization. Such is the case of the Teach for India (TFI), a non-governmental organization (NGO) working in marginalized districts of India to provide quality education to disadvantaged children through its alternative teacher credentialing program. TFI’s theory of change and intervention approach revolves around the model of Teach for All (TFA), an international movement whose model and belief of equitable educational access and opportunity continues to spread on a global scale through transnational actors. Through an extensive literature review, this article analyses critically and discusses how the TFAll’s Model is operationalised in India, through TFI that was established in 2009 to promote the universalization of Elementary Education (UEE) in India. While examining the underlying assumptions that inform the de-contextualisation of the globalised and philanthropy backed reform model, it analyses the key features of the intervention approach and presents the critiques and limitations. Beyond contextualisation, the paper makes a case for the need for non-state actors to take into account significant sociocultural and political differences in voluntary transfer of reform ideas. While acknowledging the significance of policy mobilities in bringing entrepreneurial solutions to educational problems across continents, the article recommends that such transfer must be driven by perceived necessity within local contexts.

Authors: Silva Jonas Gomes da
Published: May 2021

It complements Silva (2020b) research, which showed that among 108 well-evaluated countries, the top benchmark nations against Covid-19 are Vietnam, Taiwan, and Thailand. For example, on April 16, 2021 around 3,011,574 lives were officially lost by Covid-19, while Taiwan, Vietnam, and Thailand reported respectively only 11, 35, and 97 fatal cases (WORLDOMETERS, 2021). So, this article main aim is to investigate the Vietnam performance and the management practices used to save lives against Covid19. The research uses an online questionnaire, is descriptive with documentary and bibliographic approaches to identify management practices, including Non Pharmaceutical Interventions (NPIs) adopted against a pandemic. Also the Fatality Total Index (SILVA, 2020b p. 563) was used to compare Vietnam's performance with 43 semifinalist countries. Some results are: 1) 200 NPIs were identified across the world against coronavirus; 2) Among the 44 countries, Vietnam showed the second best performance, after Taiwan; 3) among 107 respondents living in Vietnam, only 5.61% don´t believe that cultural practices are decisive for the low rate of Covid-19 death, while most (94.39%) believe in that. From the group that believe, the most decisive cultural practices were: wear a mask, wash hands, not shake hands, not hug in public and few religious assembly; 4) for 106 respondents living in Vietnam, the ten main policy measures adopted by the National Government that saved lives against the virus are: international travel control, public information campaigns, schools closures, public event cancellations, integration with mass media, restriction on internal movement, effective public-private collaboration, increase the medical and personal equipment capacity, public transport reduction and combat fake news. At the final, ten golden lessons are provided, from 340 policies, measures, programs, projects, innovative products/services identified, with the majority led by the Public Sector (73.5%), followed by Corporations (8.5%), Others (6.5%), Start ups (6.2%), and Universities (5.3%).

Com a paralização das escolas pais, alunos e professores sejam capazes de implementar com sucesso um programa de ensino aprendizagem utilizando a nova modalidade de ensino a distância através das plataformas disponibilizadas na internet, dando continuidade da escolarização por meio de recursos tecnológicos. A importância desta pesquisa foi a possibilidade de analisar como o ensino domiciliar está sendo aplicado e comparar relatos de famílias para ajudá-las a desempenhar o auxílio educativo de forma satisfatória. O presente artigo pretende analisar o desempenho dos pais na prática docente no ensino remoto, ocasionado pela paralização das escolas devido à prevenção da disseminação da COVID-19 (doença respiratória viral pandêmica identificada em 2019, tendo como agente etiológico uma corona vírus). De modo secundário visa descrever a real consequência provocada pelo homeschooling nos pais e sua percepção acerca das vivências por eles protagonizadas nesta nova modalidade de educação; analisar a viabilidade prática da educação em casa protagonizada e mediada pelos responsáveis; analisar os limites e possibilidades de cada família neste recente cenário e como isso influenciou na experiência da educação em casa. A pesquisa foi desenvolvida por meio de um questionário on-line enviado via redes sociais para pais, ou para os responsáveis, de alunos matriculados na rede de ensino. As perguntas abordaram os possíveis desafios que a escolarização em casa e as consequências emocionais associadas a esta prática. Ficou explicito que o ensino domiciliar, na sua grande maioria, causou bastante insatisfação por parte dos pais. Além de seus afazeres cotidianos, os pais docentes tiveram de auxiliar os filhos nas atividades educacionais e complementar a didática escolhida pelos professores e escolas que geralmente envolveram o mau uso das ferramentas de ensino remoto e redes sociais. Os pais, forçadamente, se envolveram na dinâmica de ensino-aprendizagem sem a formação devida para isso. A utilização de novas propostas de ensino, teorizando de forma complementar os conteúdos das aulas, tem sido desafiador por infindas dificuldades operacionais, acabando por gerar em si alterações emocionais negativas ou potencializar as alterações desencadeadas pelo isolamento social. Em contrapartida, para uma pequena minoria dos participantes da pesquisa, o ensino domiciliar deveria ser regularizado. Isso aconteceu, quando as ferramentas educacionais para o ensino remoto foram bem utilizadas. Outro fator chave identificado foi que a boa condição financeira da família teve influência positiva na qualidade do ensino vivenciado em casa, os entrevistados deste grupo relataram mudanças significativas e ganhos de aprendizagem nos filhos no sistema de homeschooling.

Introduction: Changes in the lifestyle, food habits, lack of nutritious diet, stress, physical inactivity increases the body mass index among adults. Excess weight gain is an important risk factor for non-communicable diseases such as heart disease, stroke, diabetes, and some cancers (endometrial, breast, colon). Thus, this study aims to find out body mass index of medical students of a medical college in Nepal.

Methods: This descriptive cross-sectional study was conducted in the department of physiology of a tertiary care center from August 2019 to February 2020 after taking ethical clearence from Institutional Review Committee (Reference number 192/19). Height and weight were recorded and body mass index was then being calculated. Data entry was done in Microsoft Excel and analyzed using Statistical Package for the Social Sciences version 22.

Results: Out of 266 medical students, 39 (15%) were overweight and 32 (12%) were underweight with mean body mass index 26.60Â±1.99kg/m2 and 17.13Â±1.19kg/m2 respectively. Mean body mass index of males was 21.76Â±3.06kg/m2 and that of females was 21.70Â±2.96 kg/m2.

Conclusions: Comparing with a similar study done in Nepal previously, we found a higher prevalence of overweight in medical students whereas majority of medical students had normal weight. Factors affecting body mass index in medical students should be explored further.
Blue-eyed een erefer blue-eyed women: the role of life history strategies and sociosexuality
Authors: Gračanin Asmir , Kutnjak Kevin , Kardum Igor
Published: May 2021

Previous research (Laeng et al., 2007) conducted on Norwegian samples showed that blue-eyed men rate blue-eyed women as more attractive, while brown-eyed men and all the women show no differences in attractiveness assessments with respect to eye colour. Correspondingly, positive assortative mating was found for blue, but not brown eyes, and it most often occurred in blue-eyed men. We aimed to replicate this blue-like-blue effect in the Croatian population, which differs in the ratio of eye colour phenotypes (blue eye colour is the most prevalent in Norway while brown is the most prevalent in Croatia). Additionally, we examined whether this effect is moderated by life history strategies and sociosexuality. Our hypothesis was that the effect would be larger in those blue-eyed men who exert a slower life history strategy and who are sociosexually restrictive. One hundred and twenty-eight participants assessed the attractiveness of blue-eyed and brown-eyed models, whose eye colours were experimentally manipulated in such a way that participants were shown models with natural or artificially changed eye colours. The blue-like-blue effect was replicated in the context of preferences, although it was smaller than in the original study. However, unlike the original study, in a sample of 138 participants no assortative pairing by eye colour was found between participants and their romantic partners. Finally, the hypothesis about the moderation was supported for life history strategies, but not for sociosexuality. In addition to the rationale for the blue-like-blue effect based on the paternity uncertainty account, which was offered by the authors of the original study, we discussed other accounts of this phenomenon.
Narcissistic personality features and social trust
Authors: Beigi Dehaghi Ali Mohammad , Zeigler-Hill Virgil
Published: May 2021

Narcissism has been shown to be associated with a lack of trust in others, but little is known about the factors that may play a role in the tendency for narcissistic individuals to mistrust others. The present research examined whether the associations that specific narcissistic personality features had with social trust were mediated by social worldviews. A large study of Iranian community members (N = 3,446; mean age of 34.28 years) revealed that the antagonistic and neurotic aspects of narcissism had negative indirect associations with social trust through the competitive social worldview, whereas the extraverted aspect of narcissism had a positive indirect association with social trust through the competitive social worldview. In addition, the extraverted and neurotic aspects of narcissism had positive indirect associations with social trust through the dangerous social worldview. These results suggest that the extraverted, antagonistic, and neurotic aspects of narcissism diverged in their associations with social trust and that the dangerous and competitive social worldviews played important roles in these associations. Discussion will focus on the implications of these results for understanding the roles that social worldviews play in the connections between narcissism and social trust.
Functional altruism among agreeable and narcissistic donors
Authors: M. Drea Kelsey , Brown Mitch , F. Sacco Donald
Published: May 2021

Given the increasing popularity of crowdsourced fundraisers, understanding how characteristics of funding initiatives and donors influence donations has critical real-world implications. Across two studies, we identified potential situational factors most conducive to successful crowdsourcing while also determining whether individual differences in various personality factors predicted differing levels of donation. Participants in Study 1 (MAge = 19.99; 309 women, 75 men) viewed descriptions that manipulated donation type (organizer donation, anonymous donation, no donation) and type of fundraiser (self-organized, other-organized), and reported their willingness to donate to an individual’s medical treatment and completed inventories assessing Big Five personality traits. In Study 2 participants (MAge = 20.22; 322 women, 102 men) viewed vignettes describing fundraisers for an individual’s vacation fun and completed inventories assessing participantslevels of narcissism using the Pathological Narcissism Inventory. Higher agreeableness in men predicted heightened donation interest, regardless of type of cause, particularly when someone else has already donated (Study 1). Unexpectedly, narcissistic men and women both reported heightened donation interest (Study 2). We frame these findings through a framework assessing the adaptive utility of altruism as a function of personality in modern donation contexts.

Namun, devais yang dimiliki kurang support untuk rendering video jika PowerPoint memiliki banyak gambar dan atau video.Kata Kunci: Pembelajaran daring; covid-19; Guru Kimia; video ajar; PowerPoint ABSTRACTThe period of the COVID-19 pandemic in Indonesia which began in March 2020 forced all teaching and learning processes to be shifted to an online learning system. Apart from the absence of a teacher culture in managing online learning, the implementation of this face-to-face teaching and learning process has forced teachers to be more creative in making learning media. In addition to the practical aspects, teachers must be ready and prepared to be able to play a role as the curriculum demands. The quality of online learning has roots that are not simple, starting from the lack of online learning resources, control of study time, internet access, and so on. Referring to the description of the situation analysis, the main problems of partners can be identified, namely science teachers, especially in the in-service Chemistry Teachers group. There is an increase in the skills of teachers in describing chemical molecular structures and also the ability to prepare teaching videos using PowerPoint. However, the device does not have support for rendering video if PowerPoint has lots of images and / or videos.Keywords: online-learning; COVID-19; Chemistry Teachers; Teaching Video; PowerPoint.

OBJECTIVES:

Genetic susceptibility to cervical cancer in relation to transforming growth factor beta 1 ( TGFB1) gene polymorphisms has not been investigated extensively among the women in Bangladesh. So, the aim of this study was to find out the correlation of the polymorphisms of TGFB1 C509T (rs1800469) and T869C (rs1800470) with the risk of cervical cancer among the Bangladeshi women.

STUDY DESIGN:

134 cervical cancer patients and 102 age-sex matched healthy controls were included from two institutions in Bangladesh. Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method was used for genotyping two TGFB1 single nucleotide polymorphisms C509T (rs1800469) and T869C (rs1800470) in patients and controls.

RESULTS:

No significant correlation was found between polymorphisms C509T (rs1800469) and T869C (rs1800470) of TGFB1 gene with cervical cancer in Bangladeshi women. In case of the cervical cancer patients who had first degree relatives with cancer were prone to carry the polymorphic version of the TGFB1 gene polymorphism at C509T (OR = 5.597, 95% CI = 1.224–25.597, p <  0.05) but may not result in the increase of developing cervical cancer.

CONCLUSION:

In summary, two polymorphisms C509T and T869C of TGFB1 gene may not be associated with cervical cancer risk in Bangladeshi women.

Introdução: Os doentes asmáticos têm por vezes outras patologias concomitantes para as quais é necessário o uso de beta-bloqueantes. Tendo em conta que a terapêutica com estes fármacos é transversal a diversas doenças e sendo fármacos bastante usados na prática clínica, particularmente nas consultas de cuidados de saúde primários, torna-se importante esclarecer possíveis contraindicações ao seu uso nos indivíduos com asma. Objetivo: Avaliar os efeitos que a administração de beta-bloqueantes cardioseletivos e não seletivos podem ter em doentes asmáticos no que diz respeito a: alterações nas provas de função respiratória; exacerbações agudas da doença e sua sintomatologia associada; frequência de uso de medicação de alívio; necessidade de recorrer a um serviço de urgência e frequência de internamentos relacionados com efeitos adversos da toma do fármaco. Métodos: Foi realizada uma revisão sistemática da literatura, tendo sido utilizada a base de dados eletrónica PubMed. A expressão de busca utilizada foi: asthma AND beta-blockers. Resultados: A pesquisa inicial levou à obtenção de uma amostra de 151 artigos, dos quais 49 foram selecionados pela leitura do título e resumo. Destes, depois da leitura integral e da aplicação dos critérios de inclusão, foram escolhidos 30 artigos. O atenolol e o propranolol foram os beta-bloqueantes mais estudados. Dois ensaios clínicos randomizados e um coorte abordaram beta-bloqueantes oculares tópicos; 22 ensaios clínicos randomizados e cinco coortes estudaram beta-bloqueantes orais ou IV. Conclusões: Os doentes com asma ligeira a moderada poderão, se indicado, pela existência de outras patologias, ser medicados com beta-bloqueante, sempre com vigilância apertada do doente, especialmente nas fases iniciais desta terapêutica. Não se verificou que os beta-bloqueantes cardioseletivos sejam claramente mais seguros que os não seletivos, pelo que terão de ter os mesmos cuidados na sua utilização em asmáticos. Os beta-bloqueantes tópicos oculares podem ter efeitos prejudiciais nos asmáticos, reduzindo o FEV1 e causando exacerbações de asma. Ainda não existem dados suficientes para recomendar o uso de beta-bloqueantes para o tratamento da asma.

Most biogas units in the rural area have no smoke or fire alert safety mechanism. This has always resulted in indoor air pollution and or property damage in case of fire incidence. This unfortunate incident are preventable by installing a simple automated device to alert the owner in the event of smoke or fire for necessary action. This study focuses on a biogas leakage alarm system that alerts the owner via a buzzer, SMS, and call. The device uses an MQ-2 sensor to detect ignitable gas spillage and smoke. This high signal monitored by the Arduino Uno also leads to red LED lighting when the set smoke threshold is exceeded. The systems are portable and can be positioned in an appropriate position in the kitchen. This device is highly recommended in all the kitchens using biogas or firewood to alert the user in case of smoke indoor air pollution or fire breakout.
Study of Airborne Transmission of Covid-19 In Different Climatic
Conditions

Published: May 2021

COVID-19 is a contagious disease caused by a newly discovered virus, SARS-CoV-2. It is known to spread through respiratory droplets and contact surfaces contaminated due to deposition of infected droplets. Recently, researchers have also found evidence of airborne transmission of Covid-19. Airborne transmission takes place through formation of aerosols which remain suspended in air for longer periods of time. This transmission heavily depends on the type of surrounding physical environment. Climatic conditions like temperature, humidity, precipitation, wind velocity, air quality, etc. might impact the transmission rate of SARS-CoV-2. In this study, we examined the relationship between some of the climatic variables and daily reported cases of Covid-19. Currently, the countries with the leading number of Covid-19 cases are the USA, Brazil, India and Russia. We studied the top most affected region from each country, namely Los Angeles, São Paulo, Mumbai and Moscow, respectively. The daily number of Covid-19 cases was correlated with three climate variables individually i.e. daily average temperature, daily average humidity, and daily average wind speed. There was a significant relationship between the variables in Sao Paulo. Overall, average wind speed was found to have the most number of statistical significant correlations with daily Covid-19 cases among all the regions.
