Análise da conduta das revendedoras de gasolina comum em Salvador (BA)
Authors: Fernandes Rosangela Aparecida Soares , Jacob Kamila Gabriela
Published: December 2022

Neste artigo buscou-se verificar se há indícios econômicos de conduta colusiva na revenda de gasolina comum em Salvador-BA, no período de janeiro de 2015 a junho de 2019. Para tal, utilizou-se a metodologia sugerida pela Agência Nacional de Petróleo, Gás Natural e Biocombustíveis e pela Secretaria de Acompanhamento Econômico, e se avaliou a assimetria de transmissão de preços, a partir do modelo de correção de erros. Os resultados para a primeira metodologia sugeriram que há sinais econômicos de conduta colusiva nos postos revendedores de gasolina nesse município. Entretanto, os resultados estimados para a assimetria de transmissão de preços não permitiram concluir a respeito de indícios de cartel. Apesar disso, a hipótese de comportamento assimétrico em curto prazo não foi rejeitada, sugerindo que esse mercado não apresenta conduta concorrencial.
Competitividade do setor cacaueiro brasileiro no mercado internacional
Authors: Campos Samuel Alex Coelho
Published: December 2022

No século XXI, com a sociedade do conhecimento, exige-se um novo padrão de desenvolvimento para as economias emergentes. A questão que se apresenta é se estas, que têm seus modelos pautados nas atividades industriais e agrícolas, podem incorporar os segmentos culturais e criativos nas suas estratégias de desenvolvimento. Nesse contexto, o presente trabalho tem como objetivo discutir como o segmento cultural pode ser um vetor de desenvolvimento para o estado da Bahia. Com base em uma revisão de literatura, são levantados os limites e possibilidades de um modelo calcado no potencial de desenvolvimento cultural do estado. A principal conclusão deste estudo é que, na Bahia, o potencial de desenvolvimento econômico a partir da cultura é inegável, já que o estado é culturalmente diverso, possui produção cultural relevante em diversas linguagens e conta com um número significativo de profissionais ocupados no setor. A transformação desse potencial em resultados concretos, no entanto, esbarra em entraves que envolvem não apenas características do mercado, barreiras institucionais, problemas com distribuição e demanda, mas também a postura dos agentes produtivos perante o panorama atual. Talvez o obstáculo mais significativo resida na resistência dos agentes públicos e empresários em reconhecer a relevância econômica do setor cultural, concebendo um modelo de desenvolvimento que vá além dos setores agrícolas e manufatureiros tradicionais. Em síntese, não há, ainda, a vontade política necessária para avançar com a agenda da economia da cultura na Bahia (até mesmo no Brasil). Palavras-chave: Economia da Cultura. Desenvolvimento. Bahia.

Accountability na gestão hídrica em comitês de bacias hidrográficas: um estudo de caso no comitê do Baixo Paraíba do Sul e Itabapoana
Authors: Rangel Bruno Eduardo
Published: December 2022

A participação popular, a prestação de contas e a transparência são indispensáveis a um modelo de gerenciamento da água que almeje ser capaz de conciliar os usos múltiplos deste bem de forma democrática. Assim, o conceito de accountability compactua com a administração dos recursos hídricos adotada pelos comitês de bacia. Como objetivo, o presente trabalho busca investigar de que forma as disciplinas e práticas de accountability são usadas na gestão hídrica das regiões norte e noroeste fluminenses pelo Comitê da Bacia Hidrográfica do Baixo Paraíba do Sul e Itabapoana (CBH BPSI) e contextualizar o processo de inserção popular na administração pública regional. Para tanto, desenvolveu-se uma pesquisa bibliográfica, um estudo, por meio do método da “análise de conteúdo”, das atas de reuniões entre os anos de 2017 e 2018 – sendo que os períodos foram agrupados nas categorias “Ambiental”, “Financeiro”, “Organizacional”, “Sociopolítico” e “Accountability” – e a interpretação de entrevistas semiestruturadas, que subsidiaram um estudo de caso sobre o gerenciamento hídrico local, através de uma abordagem qualitativa, de natureza aplicada, com objetivos descritivos e exploratórios. Dessa forma, foi possível concluir que, genericamente, a gestão do CBH BPSI, ainda que sofra com baixa adesão social e interferências externas, usa conceitos de accountability no gerenciamento hídrico local.

Agriculturas e meio ambiente: uma questão permanente
Authors: Rocha Alyson dos Santos
Published: December 2022

O objetivo deste artigo é apresentar uma contribuição para o debate relativo aos impactos das agriculturas sobre o meio ambiente levando-se em consideração as recentes medidas de liberação do uso de agrotóxicos pelo governo brasileiro – alguns com severas restrições ou banidos na União Europeia – e a publicação do relatório do Intergovernmental Panel on Climate Change (IPCC), no segundo semestre de 2019. Considerando-se as diversas formas produtivas e os diferentes graus de especialização técnica e qualificação dos agricultores, tem-se grande amplitude de consequências e alternativas, estabelecendo-se variadas agendas de pesquisa que podem determinar a (re)conciliação entre a produção agrícola e o meio ambiente. Não se vislumbra uma mudança profunda nas formas de cultivo no campo nas próximas décadas. O modelo tradicional (especialização agrícola, uso intensivo de máquinas e agroquímicos) deve ainda perdurar, sobretudo pelas perspectivas de aumento da população mundial e, consequentemente, da demanda por alimentos. Nesse cenário, no entanto, existe espaço para alternativas ou formas mais racionais de produção, como a agricultura de precisão. Porém, as ocorrências no Brasil e o relatório do IPCC sugerem a constante renovação e urgência do debate. A heterogeneidade das atividades, dos agentes e dos interesses envolvidos garante a permanência da questão. Palavras-chave: Agriculturas. Meio ambiente. IPCC. Agroquímicos. Agriculturas alternativas.

Published: December 2022

As instituições ganham importância nos esforços para solução de problemas ambientais. Através dessa perspectiva, a governança ambiental é compreendida como o estabelecimento, a reafirmação ou a mudança das regras, normas ou estratégias compartilhadas para resolver os conflitos que cercam o uso dos recursos naturais. Consideradas uma inovação brasileira, as áreas de proteção ambiental (APA) são unidades de conservação de uso sustentável que visam disciplinar o processo de ocupação e assegurar a sustentabilidade do uso dos recursos naturais, constituindo-se em um excelente lócus para a compreensão da abordagem institucional da governança ambiental. Este estudo objetiva apresentar algumas questões que envolvem o uso de regras e normas que impactam o processo de governança da Área de Proteção Ambiental Costa dos Corais, criada pelo governo federal em 1997. Foram feitas duas pesquisas: exploratória e descritiva. Na primeira, utilizaram-se os procedimentos de análise bibliográfica e documental. Na segunda foi realizada uma observação qualitativa (participante observador) em reuniões feitas pelo ICMBio Costa dos Corais e pelo Conselho da APA Costa dos Corais (Conapac), além de uma entrevista. Os estudos de casos apresentados no artigo ilustram a influência das instituições no processo de governança da referida APA, que muitas vezes produz efeitos por um longo período de tempo e passa despercebida ou não é direcionada pelos gestores dessa unidade.

Published: December 2022

Os resíduos de serviços de saúde (RSS) requerem atenção especial no contexto do trabalho, adquirindo grande relevância no âmbito de um hospital veterinário devido à possibilidade de maior geração desse tipo de material. Quando mal gerenciados, esses resíduos podem provocar danos à saúde e ao ambiente. Diante da importância do fator subjetivo para um adequado manejo dos RSS, este estudo analisou as percepções dos trabalhadores do hospital veterinário de uma universidade em relação a essa questão. Uma pesquisa qualitativa exploratória foi realizada com trabalhadores do hospital veterinário de uma universidade pública. Utilizou-se o grupo focal como técnica de coleta de dados, por sua capacidade interativa e problematizadora, que possibilitou inserir os participantes da pesquisa no contexto das discussões, contribuindo para se repensar sobre concepções, práticas, atitudes e políticas públicas. A pesquisa foi desenvolvida por meio de discussões realizadas em dois grupos: um composto por nove trabalhadores estatutários da carreira de técnico administrativo em educação e outro com oito trabalhadores terceirizados. Os dados foram analisados pelo método de análise de conteúdo a partir da definição de categorias. Os resultados evidenciaram as diversas percepções dos trabalhadores sobre o manejo de resíduos, riscos à saúde, impactos ao ambiente e fatores que influenciam a adequação. Revelaram-se diferentes percepções inerentes às condições e às relações de trabalho, ficando evidente a necessidade de melhorar a estrutura da instituição pesquisada, instituir programas de capacitação e aprimorar as condições de trabalho para possibilitar a participação de todos os trabalhadores em um processo adequado de manejo de RSS.

A INCORPORAÇÃO IMOBILIÁRIA E O PAPEL DO PODER PÚBLICO MUNICIPAL NO PROCESSO DE EVOLUÇÃO URBANA DO MUNICÍPIO DE DOM BASÍLIO (BA)
Authors: Ramos Alex Moreira , Nunes Filho Fernando Barreto
Published: December 2022

A evolução urbana decorrente do crescimento populacional em cidades médias e pequenas costuma ocorrer do centro dessas cidades para as áreas periféricas ou mesmo para áreas rurais. Para o economista Singer (1980, p. 84), as cidades no Brasil se caracterizam pela importância de um centro principal definido pela localização comum da administração pública e da igreja matriz: “[...] os tribunais, o distrito financeiro, o comércio atacadista, o comércio varejista de luxo, cinemas, teatros etc. Os serviços urbanos se irradiam do centro à periferia, tornando-se cada vez mais escassos à medida que a distância do centro aumenta. [...]”. Nesse sentido, a produção imobiliária intensifica a expansão da cidade e consequentemente a necessidade de extensão das redes de infraestrutura urbana e serviços públicos. Naturalmente, a definição sobre a localização de infraestrutura atribui ao poder público um papel fundamental na valorização de terras públicas, articulando-se com o mercado imobiliário urbano.
EFFECT OF ENTOMOPATHOGENIC FUNGI BEAUVERIA BASSIANA ON THE CELLULAR IMMUNITY AND BIOCHEMISTRY OF GREEN BUG NEZARA VIRIDULA L.
Authors: Gad Abir A. , Nada Maha S.
Published: December 2022

Entomopathogenic fungi (EPF) are considered effective methods for investigating insects’ immunity in response to infection. Insects have a variety of defense mechanisms against infectious diseases, namely phenoloxidase, hemocytes, detoxification and antioxidant enzymes.The instinctive immune system of insects is highly advanced and depends on humoral and cellular elements. In this study, five haemocytes types were found in fifth nymphal instar and adults of green bug, Nezara viridula (Heteroptera: Pentatomidae) namely; prohaemocyte (pr),granulocyte (gr), spherulocyte (sp), plasmatocyte (pl), coagulate cells (co) and oenocytoid (oe). Infection with Beauveria bassiana significantly decreased the different haemocytes count in both fifth nymphal instar and adults, especially after 72h post-infection. The haemocytes’ response against fungi was also investigated. A significant increase in Alpha esterase (EST), Acid phosphatise (ACP) and Alkaline phosphatise (ALP) were observed after 72h post infection in the haemolymph of N. viridula adults. In contrast, phenoloxidase activity significantly decreased in adults’ hemolymph after the same period of infection. Results indicated that infection with B. bassania affects the number of circulating haemocytes and decreases phenoloxidase activity.

Nowadays customer service, pricing strategies and trade credit financing scheme are effective, essential and survival parameters for any kind of business setup in the market. In this study we have developed retailer’s ordering policy for imperfect production in which we have applied the learning effect on inspection process on each and every batch of imperfect product. To stimulate sales of product and to study the effects of trade credit financing scheme on retailers business policy we have applied trade credit financing scheme on retailers ordering policy. In this paper, we have developed, an economical order quantity (EOQ) model for retailer’s price sensitive demand of product under two stage trade credit financing scheme. In the trade credit financing scheme we have assumed that the supplier offers to the retailer a fixed credit period of payment and the retailer also offers t a fixed credit period of payment o his customers. An optimal total profit function per unit time has been formulated under the different trade credit financing periods of payment with different costs and related parameters. A numerical example has been designed to verify the optimum results also we have done sensitive analysis through tables and graphically.

MATHEMATICAL MODELLING AND SENSITIVITY ANALYSIS OF EFFECT OF GLOBAL WARMING ON CARRIER BASED INFECTIOUS DISEASES
Authors: Singh Arora Maninder , Singh Shikha , Omar Ashish , Mishra S. N.
Published: December 2022

The effect of global warming on the proliferation of carrier dependent infectious diseases is exigent. In this paper, we have proposed and analysed a non-linear mathematical model to study the deleterious effect of rise in global temperature on the spread of carrier dependent infectious diseases due to increased carrier immigration. The model comprises five dependent variables, namely, the density of susceptible population, the density of infected population, the density of carrier population, the concentration of carbon dioxide and the global average temperature. Driven by existing literature and data, the global average temperature is assumed to be proportional to the increased level of CO2 . The natural as well as anthropogenic emissions that result in the upward climb of CO2 concentration in the atmosphere are considered in the model. The carrier population is assumed to grow logistically. The long-term behaviour of the model is estimated through the stability theory of differential equations. A basic differential sensitivity analysis is also conducted to assess the sensitivity of model solutions with respect to key parameters of the dynamical system. Numerical simulations are carried out to illustrate the analytical results.

Let H′α,β be the Zemanian type space of Hankel transformable generalised functions and let O′α,β,* be the space of Hankel convolution operators for H′α,β . This H′α,β is the dual of a subspace H′α,β of O′α,β,* for which O′α,β,* is also the space of Hankel convolution. In this paper the elements of O′α,β,* are characterised as those in L(Hα,β) and in L(H′α,β) that commute with Hankel translations. Moreover, necessary and sufficient condition on the generalised Hankel type transform h′α,βS of S ∈ O′α,β,* are established in order that every T ∈ O′α,β,* such that S ∗ T ∈ Hα,β lie in H′α,β.

Research on the diurnal dynamics of the leaf photosynthetic intensity under the same illumination conditions have shown that the photosynthesis of the seedlings was controlled by circadian cycles. The studies related to the dependence of the photosynthesis intensity on the light spectral composition showed that the red part of light spectrum with a wavelength of 660 nm had the greatest effect on photosynthesis in D. turbinatus. The results of dependence was described by a quadratic equation with a high degree of accuracy of the approximation (R2 ~ 1.0). The main conclusion that, in the studies related to plant photosynthesis, in addition to generally environmental factors that have been traditionally considered for in previous similar studies, their circadian rhythms should be taken into account.

The study investigates and analysis the effect of climate factors, including monthly total rainfall, temperature and monthly average humidity, on cambium activity of Pinus krempfii in Bidoup - Nui Ba National Park, VietNam. The result showed that cambium activity of this species changes with the seasons significantly, which is slow or dormant in the dry season (from January to April and December) and strong in the rainy season (May to November). The correlation analysis between the cambium’s numbers and climatic factors showed that there are very high positive correlations for humidity (r = 0.842) and temperature (r = 0.788); there is a rather high positive correlation for rainfall (r = 0.679). The study’s result reveals the climate’s conditions which are suitable to diameter’s growth of the species, so it contributes to the conservation’s efforts of this rare species.

Currently, two species of the Asian Agile skinks genus Subdoluseps, including S. bowringii and S. vietnamensis, occur in Vietnam. The former is widely distributed throughout the country while the later has been recorded in the coastal areas of Binh Thuan and Ba Ria-Vung Tau provinces. Analyses of 46 stomach samples of the S. bowringii and 39 stomach samples of S. vietnamensis collected at 17 locations in southern Vietnam resulted in recording of 17 food groups of six classes of Invertebrates and one class of Vertebrate animals. Two skinks share 9 of 17 common food groups (52.9%). The Insecta class dominated with 8/17 groups (47.1%) observed. Among the Insecta, Blattodea order occupied the highest percentage and followed by Coleoptera, Dermaptera orders, and insect larvae. The Araneae, Scolopendromorpha, Squamata, and Isopoda orders are also prioritized by these two species. Subdoluseps bowringii eats 14 food groups, the Insecta class dominates with 7/14 groups (50%) with the Blattodea order being the highest frequency (63.0%). The S. vietnamensis eats 12 food groups, the Insecta class dominates with 5/12 groups (41.7%) with the Blattodea order being the highest frequency (74.4%). In addition to animals, other components such as soil (2.2%) and leaves (2.6%) were also recorded in the stomachs of the two species.

The effect of velocity on initial electrochemical behavior and corrosion state of AH36 shipbuilding structural steel was studied in the laboratory. Open-circuit potential, electrochemical impedance spectroscopy and linear polarization were used to evaluate the electrochemical properies. Corrosion rate was determined by mass loss method. The results showed that the surface electrochemical behavior changed rapidly in a short time and was stable up to 7 days before achieving a stable value. There was a difference between samples in flowing compared with stationary samples. Velocity of sea water flow did not only accelerate the higher steel corrosion rate in the same conditions, but also cause uneven surface corrosion due to non-uniform self-dissection of the corrosion product.

This paper presents the results of natural testing at 3 natural testing stations of the Vietnam-Russia Tropical Center for a period of 5 years on popular polyurethane coating systems. The tropical durability of the product is assessed by the variation of the decorative and protective properties of the coating systems during the test. The study shows that, among the climate-environmental parameters, the order of influence is: UV radiation intensity, sea salt level, temperature-humidity combination, oxidizing agents. The degradation properties of the paint systems are similar, although the degradation rates are different when tested under different conditions. The variation of gloss, thickness, color fastness and anticorrosion effect of the PU paint coatings is highly correlated with the exposure time, showing the possibility of using functions in predicting the working life of these coatings.

Published: December 2022

The amerophidian snake radiation is a Late Cretaceous superfamily that encompasses two families: Aniliidae, pipe snakes, and Tropidophiidae, dwarf boas. We describe a new dwarf boa snake species, from the Tropidophiidae family, from the cloud forest in northeastern Ecuador. Tropidophis cacuangoae sp. nov. can be diagnosed from its congeners based on external and osteological morphology. The new species inhabits eastern tropical piedmont and lower evergreen montane forests, in the Amazon Tropical Rainforest biome, and is likely to be an Ecuadorian endemic. We also discuss the relationships of the new species with South American tropidophiids and provide a key to the identification of mainland South American dwarf boas.

Published: December 2022

Introducción:La vulvovaginitis es uno de los principales motivos de consulta ginecológica en niñas prepúberes. No es común que las bacterias del género Shigella sean las causantes,  pero  se  han  reportado  casos  con  lesiones  típicas  con  microulceraciones. Objetivo: Encontrar asociación entre la infección por Shigella flexneri y la presencia de microulceraciones vestíbulo vaginales en niñas prepúberes que acudieron al Instituto Nacional de Salud del Niño (INSN) entre los meses de diciembre de 2008 y noviembre del 2009. Materiales y métodos: Se hizo un estudio observacional, analítico y transversal que evaluó una muestra de 149 niñas de 0 a 9 años mediante un muestreo sistemático. Los criterios de inclusión incluyeron pacientes con vulvovaginitis específica y hallazgos de microulceraciones; y a aquellos que no tenían la infección. Se utilizaron pruebas de bivariadas como chi-cuadrado, el test exacto de Fisher; además se calcularon medidas de asociación mediante modelos lineales generalizados. Resultados: Del total de pacientes, se encontró que el 56,5% dio positivo a Shigela flexneri y el 48,9% presentó microulceraciones y,  de estos últimos, el 95,8% presentaron flujo sanguinolento (p<0,001). Asimismo, se encontró asociación entre la presencia de microulceraciones y el cultivo positivo a Shigella flexneri (p<0,001) y de la misma manera cuando se hizo la comparación otras especies de Shigella (p<0,001); estas diferencias significativas se perdieron en el análisis multivariable. Se encontró una asociación fuerte entre la presencia de flujo sanguinolento y la presencia de microulceraciones (RP=17,84; IC 95%: 5,21-61-05; p<0,001). Conclusión: Existe asociación entre el cultivo positivo a Shi  ella flexneri y la presencia de microulceraciones vestibulovaginales en niñas prepúberes.
Clinical studies of dapagliflozin in pediatric patients: a rapid review
Authors: Grube Paige M. , Beckett Robert D.
Published: December 2022

The oral sodium-glucose cotransporter 2 inhibitor, dapagliflozin, is used to treat kidney disease, heart failure, and diabetes in adults, but has not been well studied in pediatrics, and does not have a recognized place in therapy in current practice guidelines. The purpose of this review is to summarize studies that have investigated the efficacy of dapagliflozin in pediatric patients. A systematic review was performed to identify clinical studies of oral dapagliflozin in children 0 to 17 years. Studies were identified through searches of Scopus, Web of Science, PubMed, Google Scholar, Embase, clinical trial registries, research registries, and key journals through August 2022. The Cochrane scoring system was used to assess the methodological quality of the included randomized trials. Five studies were reviewed and included in this analysis. Dapagliflozin at a dose of 5 to 10 mg was utilized in adolescents and young adults with heart failure, chronic kidney disease with proteinuria, type 1 diabetes, or type 2 diabetes. Studies evaluating dapagliflozin in type 1 diabetes evaluated single doses while the other studies monitored long-term use. Dapagliflozin was overall considered to be safe and effective in the studies included in this review, but further studies in larger populations and over extended periods of time are necessary.
