TURISMO E DESENVOLVIMENTO: TRANSFORMAÇÕES NO TERRITÓRIO DA REGIÃO DO EXTREMO SUL DA BAHIA
Authors: Cerqueira Neto Sebastião Pinheiro Gonçalves de , Da Silva Leonardo Thompson
Published: November 2022

O turismo se tornou um setor de extrema importância para a economia de países, regiões e cidades; muitas vezes visto como a salvação econômica dos lugares. No Extremo Sul da Bahia não é diferente, a região com sua beleza litorânea tem se transformado para atender o chamado trade do turismo. Este artigo não apresenta uma crítica pela crítica sobre o turismo, mas, convida para uma análise de um cenário onde o turismo aparece como uma solução inquestionável para se atingir um estágio de desenvolvimento. A reflexão que se apresenta mostra o perigo da especialização espacial para a economia e a perversidade do desenvolvimento que exclui social e economicamente a maioria dos moradores das cidades turísticas.
ATRIBUTOS QUÍMICOS DO SOLO EM ÁREAS SOB DIFERENTES SISTEMAS DE USO E MANEJO NO MUNICÍPIO DE RESERVA - PR
Authors: Pereira Adalberto Alves , Thomaz Edivaldo Lopes
Published: November 2022

Este estudo objetivou avaliar as propriedades químicas dos solos comparando diferentes sistemas de manejo, uma vez que o entendimento das modificações ocorridas nas propriedades químicas e físicas, decorrentes do seu cultivo, pode fornecer elementos para produção em bases sustentáveis. Foram escolhidas três áreas cultivadas com feijão (F1, F2 e F3); uma com pastagem (Pt); e uma com floresta (Ft) para realização deste estudo. As áreas foram divididas em três setores, sendo: alta, média e baixa encosta. Em cada setor foram abertas pequenas trincheiras onde foram coletadas três sub-amostras de solo nas profundidades (0-0,05; 0,05-0,15; 0,15-0,30 m). Após coleta as amostras foram catalogadas e enviadas a um laboratório credenciado para análise de macronutrientes, matéria orgânica e pH do solo. O teor de matéria orgânica e a saturação de bases foram os parâmetros químicos que melhor representaram as diferenças entre as formas de manejo. A área F2, por ter sofrido a queima em um estágio de tempo mais recente que as demais áreas, apresentou melhores condições químicas, superiores e/ou semelhantes aos da área de floresta. Conclui-se que o manejo do solo tem maior efeito sobre os atributos químicos do que o tempo de manejo, já que a área F3 (30 anos de manejo) apresentou condições químicas superiores Ã  área F1 (10 anos de manejo).

Authors: Alvarenga Cibele Andrade de , Ribeiro Áurea Aparecida , Dos Santos Charles Ianne Ferreira
Published: November 2022

O estudo objetivou-se analisar a modificação da vegetação arbórea no perímetro urbano de Itabira nos anos de 1990 e 2007 usando ortofotos da CEMIG (1990), aerofotogrametria (2007) e mapas. Utilizou-se o ArcGis 9 - ArcMap, Versão 9.3 e o Sistema de Informação Geográfica (SIG - ArcMap) com a finalidade de quantificar os fragmentos de vegetação e avaliar a dinâmica antrópica na área urbana do município. No ano de 1990 haviam 242 fragmentos vegetais distribuídos ao longo de toda área urbana de Itabira, que totalizavam 13,26 KmÂ² ou 25,27% da área. Já em 2007 foram encontrados 284 fragmentos totalizando 13,96 KmÂ², 26,6% da área urbana, resultando-se em um acréscimo de 1,33% da vegetação. Foram verificadas alterações nos fragmentos devido à expansão da mineração local e expansão do município. A revitalização e conservação dos fragmentos de mata é uma opção ecológica para o município de Itabira.
PNLD E O PROCESSO DE AVALIAÇÃO: GUIAS DO LIVRO DIDÁTICO DE GEOGRAFIA (2013-2015)
Authors: Carvalho Diana dos Reis Pereira , Veloso Filho Francisco de Assis
Published: November 2022

Após várias denominações, a política de distribuição de livros didáticos transformou-se no Programa Nacional do Livro Didático (PNLD) em 1985. As discussões sobre a qualidade no ensino originaram definições para avaliar as coleções, apresentadas no primeiro guia do livro didático (1996). O objetivo é caracterizar a metodologia de avaliação do livro didático de geografia, mediante guias PNLD (2013-2015). A pesquisa baseia-se em bibliografias, decretos, Guias de Geografia 2013-2015 e livros selecionados. A produção do livro didático estabelece-se com a criação do Conselho Nacional do Livro Didático (1938), transformado no PNLD, ensino fundamental, em 1985 e desdobrando-se para o Ensino Médio, PNLEM, em 2003. O guia do livro didático é um documento que destaca o resultado e a metodologia de avaliação, caracterizando as exigências comuns para todas as áreas do conhecimento e para cada componente curricular, subsidiando a escolha do professor. Verifica-se que os livros de geografia quanto à abordagem conceitual, buscam relacionar o conteúdo geográfico ao cotidiano; o construtivismo piagetiano e o socioconstrutivismo são a base da abordagem didático-pedagógica; consolidando com a observância ética e democrática. Portanto, as coleções de geografia apresentam atualização dos temas, informações e conceitos geográficos corretos, a partir de uma perspectiva crítica.

Published: November 2022

O conceito de logística reversa ganha cada vez mais importância como uma ferramenta empresarial, para que as organizações gerenciem todo o ciclo de vida de seus produtos, atendendo a exigências legais, governamentais e dos consumidores. Este artigo tem como objetivo averiguar a compreensão do conceito de logística reversa entre os empresários do comércio varejista de informática em Frutal-MG, bem como a visão e a atuação governamental para o gerenciamento dos resíduos eletroeletrônicos. A partir das entrevistas e, sobretudo dos trabalhos de campo conclui-se que há a ausência de infraestrutura logística entre as empresas do setor e também no âmbito do poder público. Em relação à destinação final dos resíduos, uma parte vai para o mercado secundário, portanto é (re)aproveitada. Contudo, aqueles resíduos que não tem (re)aproveitamento, geralmente, são descartados no lixo comum. Contudo, novas perspectivas surgem, uma vez que a Prefeitura Municipal de Frutal, em parceria com a Universidade do Estado de Minas Gerais e a Fundação Unesco-HidroEX, está implantando o posto de recebimento para tratamentos e destinação correta dos resíduos de informática.
ANÁLISE DA DINÂMICA DO USO E COBERTURA DO SOLO EM BLUMENAU (SC), UTILIZANDO FERRAMENTAS DE GEOPROCESSAMENTO
Authors: Cardoso Fabricio Baumgarten , Centeno Jorge Antônio Silva
Published: November 2022

Este trabalho teve como objetivo avaliar a dinâmica do uso e ocupação do solo no município de Blumenau através de imagens de satélite Landsat e de ferramentas de geoprocessamento. Foram obtidas imagens do satélite Landsat8, de 23/08/2014, que abrangem o município de Blumenau. As imagens foram classificadas pelo método de Classificação Supervisionada por Máxima Verossimilhança (MaxVer). Analisou-se a dinâmica do uso do solo comparando-se estes dados, com o trabalho realizado por Refosco (2000) para o ano de 1997. Os resultados para a área total de Blumenau apontaram uma diminuição da Vegetação Nativa em 9,0%, um aumento da área de Reflorestamento em 142,4%, um aumento da Área Urbanizada em 31,5%, diminuição da cobertura de Rios e Águas em 13,6% e um aumento da classe Agricultura/Pastagem em 18,6%. Entre 1997 e 2014, ocorreu uma diminuição de área de vegetação nativa e aumento de área urbanizada no perímetro urbano. Apesar de os bairros da região norte serem os que possuem maior cobertura por vegetação nativa, de 1997 para 2014 ocorreu uma diminuição no percentual de Vegetação Nativa em todos os bairros da região Norte e um aumento em sua área de agricultura/pastagem.

Published: November 2022

As brigadas de incêndio exercem papel de combate e prevenção a incêndios florestais, sendo que os trabalhos de vigilância têm como alvo operacional a busca por presença de focos ativos. O monitoramento pontual em locais susceptíveis a queima ainda é um tema pouco trabalhado devido à variabilidade dos fatores que contribuem para a proliferação do fogo, tais como as condições do material combustível. Neste contexto, a presente pesquisa teve como objetivo avaliar a dinâmica de tendência de proliferação da queima, em função dos agentes dispersores, através da correlação dos índices espectrais NDVI e NDWI em relação à extensão dos fragmentos de queimadas. Os dados foram integralizados a árvore de decisão que estabeleceu um conjunto de regras, baseado nas observações de seca antes do início do incêndio. Em resposta ao processamento empregado, obteve-se um algoritmo capaz de mapear as áreas sensíveis ao fogo em função da condição da vegetação seca. Neste estudo, foi possível pré-determinar cerca de 20% dos fragmentos encontrados pós-queima, resultado que pode auxiliar as equipes de brigadistas no combate e prevenção aos incêndios florestais, determinar as áreas prioritárias quanto ao monitoramento pontual, dos locais susceptíveis a queima.

Authors: De Souza Ueliton Basílio , Santos Pablo Santana , Brandão Paulo Roberto Baqueiro
Published: November 2022

O Agronegócio iniciou sua expansão nos Cerrados do estado da Bahia no final da década de 1970, e a cidade de Barreiras por ocupar uma posição centralizadora na mesorregião do Extremo Oeste Baiano acabou por sofrer os maiores impactos da implantação da agricultura moderna. O artigo analisa o desmatamento ocorrido no município de Barreiras-BA e avalia o impacto desta ocupação histórica na expansão da área urbana deste município, em intervalos temporais de dez anos, tendo como subsídio as imagens dos satélites MSS/LANDSAT-2 e TM/LANDSAT-5. Assim, buscou-se trazer a configuração espacial urbana e municipal estabelecida no município a partir da instalação da agricultura moderna na década de 1980. É necessário entender de forma clara e crítica os impactos gerados sobre Barreiras, para que a compreensão dos erros que foram cometidos no passado possa auxiliar na implementação de política públicas que enfrentem os problemas sociais e estruturais que afligem a população.

Landfill Site Selection for Solid Waste Using GIS-based Multi-Criteria Spatial Modeling
Authors: Aziz Rostam S.
Published: November 2022

This study gains insight into landfill sites with the observance of all the political, economic and environmental difficulties for the implementing appropriate site measures by adopting a collection of geospatial technique and weighted linear combination (WLC) in TqaTaq sub-district. In the current study, there are several areas determined as appropriate sites for landfill location. In this study, the criteria of distance from the roads, the city center, rivers, surface water, and land use map were used. According to this analysis, only 25.21% of the TaqTaq sub district is suitable for a landfill. Thus, basing on the findings, 20.93% of the concerned sub-district is regarded as least adequate site for this mission, whereas only 3.25% of the area is regarded as moderate suitable. Thus, this study has found out that 1.03% area is the most suitable. The majority of suitable area was located in the North of the Town, where waste production is more than other locations. It should be noted that based on the outcome of this study, the amount of waste produced in the TaqTaq Town for the next 10 years, from 2022 to 2032, is predicted to be about 4080 tons. According to the density calculated for the waste of this area and considering the height of 4 m for the landfill center, in the next 10 years, about 3000 m2 of land is required for the landfill location. Since the suitable area found in this research is about 15 hectares.
Numerical Investigation of the Effect Dimensions of Rectangular Sedimentation Tanks on Its Hydraulic Efficiency Using Flow-3D Software
Authors: Javadi Rad Mohammad , Eshaghieh Firoozabadi Pedram , Rostami Fatemeh
Published: November 2022

Settling basins are among the essential units built to separate sediment suspended and within the inlet flow particles in water and wastewater treatment plants and irrigation canals. These basins' high efficiency requires proper design, creating a smooth and uniform flow along the basin, and reducing circulation zone as a factor in disrupting the sedimentation process. The present study investigates basin dimensions' effect on its flow pattern. Hence In the current study, the primary rectangular sedimentation basin was modelled three-dimensionally using Flow-3D software. This software takes advantage of two new advanced technique of VOF and FAVOR to model the free surface of the flow and the geometry, respectively. The dimensions of the basin were examined in two scenarios. In the first set-up, the length-to-width ratio was evaluated by increasing length and decreasing width simultaneously and the second part examined the length to depth ratio by decreasing depth and increasing width. In both situations, the volume and location of the inlet and outlet of the basin were constant and unchanged. The outcomes indicate that increasing the ratio of length-to-width and length to depth reduces the volume of the circulation zone significantly. The volume of these zones decreased from 53% for the L/W ratio of one (square basin) to 22% associated with the L/W ratio of eight. Likewise, the volume of these zones decreased by 38% as a result of increasing the L/d ratio from five to ten.

Published: November 2022

Convective heat transfer of laminar forced convection in a wavy channel is studied in this paper. Numerical simulations of the 3D steady flow of Newtonian fluid and heat transfer characteristics are obtained by the finite element method. The effects of the Reynolds number (10 ≤Re≤1000), number of oscillations (0 ≤N≤5) and amplitude of the wall (0.05 ≤A≤0.2) on the heat transfer have been analyzed. The results show that the average Nusselt number is elevated as the Reynolds number is raised, showing high intensity of heat transfer, as a result of the intensified effects of the inertial and zones of recirculation close to the hot wavy wall. The rate of heat transfer increases about 0.28% with the rise of the number of oscillations. In the transfer of heat along a wavy surface, the number of oscillations and the wave amplitude are important factors. With an increment in the number of oscillations, the maximal value of the average velocity is elevated, and its minimal value occurs when the channel walls are straight. The impact of the wall amplitude on the average Nusselt number and dimensionless temperature tends to be stronger compared to the impact of the number of oscillations. An increase of the wall amplitude improves the rate of heat transfer about 0.91% when the Reynolds number is equal 100. In addition, when the Reynolds number is equal 500, the rate of heat transfer grows about 1.1% with the rising of the wall amplitude.
Study on the random walk classification algorithm of polyant colony
Authors: Qiu Wenhai
Published: November 2022

With the sustained and healthy development of economy, saving energy and reducing consumption and improving energy utilization rate is a major task that enterprises need to solve. With the complex and large-scale chemical process, the heat exchange network has become complex and diverse. For more and more complex and large-scale industrial heat exchange networks, there are many different kinds of heat exchangers, the flow is complex, so the heat exchange network presents a high degree of complexity, a node status change; its disturbance transfer will influence the stability of other nodes associated with it, because of the system coupling, thus affecting the controllability and reliability of the whole heat exchanger network. Process optimization design of heat exchange network is one of the main methods of energy saving in the industrial field. As a typical simulated evolutionary algorithm in swarm intelligence algorithm, ant colony algorithm combined with random walk classification algorithm, this article proposes an optimized heat transfer network based on multi-ant colony random walk classification algorithm. The heat exchanger was abstracted as a node, and the heat exchanger pipeline was abstracted as a side. According to the maximum geometric multiplicity of the eigenvalue of the adjacency matrix and the linear correlation row vector of the matrix, and combining the importance of the edge of the heat exchange network with the controllable range of the driving edge, the optimal control driving edge of the heat exchange network is identified. The results show that compared with the traditional heat exchanger, the size of the enhanced heat transfer equipment and the influence of pressure drop change. Compared with the results of the size of the heat exchanger strengthening heat transfer equipment and the stepwise optimization of the heat exchange network in this study, the cost of public engineering is reduced by 5.98% and the total cost is reduced by 8.83%.
Occam’s razor and Hickam’s dictum: a dermatologic perspective
Authors: Stein Hadassah , Lowenstein Eve J.
Published: November 2022

Diagnostic heuristics help ease the cognitive load in our day-to-day work. Occam’s razor or the rule of diagnostic parsimony is a diagnostic heuristic often applied in dermatology. Occam’s razor dictates that all things being equal, one diagnosis (as opposed to several diagnoses) should be sought to explain a patient’s presentation. While this can often be helpful, it can also obscure the full picture. Hickam’s dictum is an aphorism expressing the opposite opinion: “patients can have as many diseases as they damn (or darn) well please.” This acknowledges that multiple simultaneous processes can be at play. This article delves into the implications of use of these approaches and offers tips through cases illustrating the limitations of Occam’s razor and when Hickam’s Dictum should be invoked.

Objectives

This study evaluated the effects of Crude Methanol Extract of Adansonia digitata Fruit Pulp on Naja nigricollis Venom-Induce Toxicity in Wistar rats.

Methods

A. digitata was extracted using 70% methanol and median lethal dose (LD50) of both the extract and venom were determined using the up-and-down method. Sixty Wistar rats were randomly assigned into 10 groups of 6 rats each and were administered with normal saline, venom only, venom + antivenom, 125 mg/kg, 250 mg/kg and 500 mg/kg crude methanol extract (CME) pre-envenomation, 125 mg/kg, 250 mg/kg and 500 mg/kg CME post-envenomation, and venom + antivenom + 250 mg/kg CME, respectively. Blood samples were collected 8-h post-envenomation in EDTA and plain sample bottles. Erythrocyte osmotic fragility (EOF) test was carried out on the EDTA blood samples while serum was harvested and used for Malondialdehyde (MDA) and Superoxide Dismutase (SOD) assays.

Results

LD50 of the CME and venom was >5,000 mg/kg and 0.889 mg/kg, respectively. N. nigricollis-induced oxidative stress was evident in group B through increased % haemolysis, MDA and lowered SOD activities. The groups treated with antivenom only, 250 mg/kg CME post-envenomation and antivenom +250 mg/kg CME significantly (p<0.05) reduced EOF, MDA values and increased SOD. The CME revealed better ameliorative effect than protective via inhibition of EOF, MDA values and increased SOD activity.

Conclusions

The CME when administered singly showed more ameliorative properties and the combination of CME with antivenom for protection was not as effective as when compared to single administration.
Vom Soldatenstande: Überlegungen zu einer Alltagsgeschichte von Soldaten im 18. Jahrhundert
Authors: Mann Michael
Published: November 2022

In den vergangenen drei Jahrzehnten ist dem Alltagsleben von Soldaten des 18. Jahrhunderts verstärkt Aufmerksamkeit geschenkt geworden. Dabei zeigte sich, dass Soldaten über ihre »Nebentätigkeiten« als Pfuscher in den Garnisonstädten oftmals in Konflikt mit den zünftisch organisierten Gewerken kamen. Es zeigte sich auch, dass verheiratete Soldaten mit ihren Frauen, die vielfach Lebensmittel verkauften oder im Textilbereich tätig waren, eine wichtige Funktion im Wirtschaftsleben einer Garnisonstadt einnahmen. Weitaus mehr als bislang angenommen, so wird hier argumentiert, waren Soldaten mit ihren Familien Bestandteil der frühneuzeitlichen urbanen Gesellschaft. Zum einen umfasste diese Personengruppe bis zur und bisweilen über die Hälfte der städtischen Bevölkerung, was unter sozialen und ökonomischen Aspekten bislang außer Acht gelassen wurde. Zum anderen waren Soldaten und ihre Frauen nicht nur Produzenten und Verteilerinnen von Waren, sondern mit ihren Familien in erheblichem Maße auch Konsumenten. Und schließlich bot sich gerade für die unverheirateten Soldaten in der Stadt durchaus die Chance zum wirtschaftlichen und sozialen Aufstieg, wenn sie in die städtische Gesellschaft einheiraten konnten.
The Effects of the “Sling Shot” Device on Bench Press Performance, Mechanical Properties of Muscle, and Movement Kinematics

Wojdała, G and Krzysztofik, M. The effects of the “sling shot” device on bench press performance, mechanical properties of muscle, and movement kinematics. J Strength Cond Res XX(X): 000–000, 2022—This study aimed to evaluate the influence of the sling shot support device at various external loads and intensities of effort, taking into account acute changes in power performance, mechanical muscle properties, and bench press kinematics. For this purpose, 12 resistance-trained men (age: 27.1 ± 4.2 years, body mass: 90.3 ± 16.9 kg, bench press [BP] 1 repetition maximum [1RM]: 112.7 ± 23.1 kg) (resistance training experience: 6.9 ± 3.8 years) participated in the study. Each subject completed 2 experimental sessions that differed in the use of the sling shot (SS) or nonuse (CONT) of the SS and an appropriate external load. The 2 experimental sessions consisted of the 1RM test, 3 sets of 2 repetitions of BP with the load increased in each set (50-70-90% 1RM), and a fourth set of the BP efforts to muscle failure with a 70% 1RM load. Before and after each set, the changes in triceps brachii oscillation frequency and stiffness were assessed by means of myotonometry. Results indicated a significant main effect of the SS to increase peak power (p < 0.0001, η2 = 0.733). Furthermore, a significantly higher 1RM (129 ± 26 vs. 113 ± 23 kg, p < 0.001, effect size [ES]: 0.63), number of repetitions (15 ± 3 vs. 13 ± 2, p = 0.013, ES: 0.76), and time under tension (34 ± 10 vs. 29 ± 6 seconds, p = 0.017, ES: 0.59) were found during the set to failure for SS in comparison to the CONT condition. Moreover, there was a significant main effect of time to increase oscillation frequency (p = 0.001; η2 = 0.666) and stiffness (p = 0.002; η2 = 0.613) from pre- to postset measure. In addition, the main effect of the side (p = 0.034; η2 = 0.348) was reported to show higher stiffness on the dominant than on the nondominant side in the CONT condition. The results suggest that an independent 1RM measurement and a correspondingly higher workload are required to take full advantage of the SS device. Moreover, the SS can also be used successfully to increase training volume and the involvement of nondominant limbs during a bench press.
Preferential Modulatory Action of 5-HT2AReceptors on the Dynamic Regulation of Basal Ganglia Circuits
Authors: Guilhemsang Lise , Gutierrez-Ceballos Amaia , Antonazzo Mario , Mallet Nicolas P. , Ugedo Luisa , Morera-Herreras Teresa
Published: November 2022

In rodents, cortical information is transferred to thesubstantia nigra pars reticulata(SNr) through motor and medial prefrontal (mPF) basal ganglia (BG) circuits implicated in motor and cognitive/motivational behaviors, respectively. The serotonergic 5-HT2Areceptors are located in both of these neuronal networks, displaying topographical differences with a high expression in the associative/limbic territories, and a very low expression in the subthalamic nucleus. This study investigated whether the stimulation of 5-HT2Areceptors could have a specific signature on the dynamic regulation of BG circuits, preferentially modulating the mPF information processing through trans-striatal pathways. We performedin vivosingle-unit extracellular recordings to assess the effect of the 5-HT2Aagonist TCB-2 on the spontaneous and cortically evoked activity of lateral and medial SNr neurons in male rats (involved in motor and mPF circuits, respectively). TCB-2 (50–200 µg/kg, i.v.) increased the basal firing rate and enhanced the cortically evoked inhibitory response of medial SNr neurons (transmission through the direct striato-nigral pathway). A prior administration of the preferential 5-HT2Areceptor antagonist MDL11939 (200 µg/kg, i.v.) did not modify any electrophysiological parameter, but occluded TCB-2-induced effects. In animals treated with the 5-HT synthesis inhibitor pCPA (4-chloro-dl-phenylalanine methyl ester hydrochloride), TCB-2 failed to induce the above-mentioned effects, thus suggesting the contribution of endogenous 5-HT. However, the mobilization of 5-HT induced by the acute administration of fluoxetine (10 mg/kg, i.p.) did not mimic the effects triggered by TCB-2. Overall, these data suggest that 5-HT2Areceptors have a preferential modulatory action on the dynamic regulation of BG circuitry.

SIGNIFICANCE STATEMENTMotor and medial prefrontal (mPF) basal ganglia (BG) circuits play an important role in integrative brain functions like movement control or cognitive/motivational behavior, respectively. Although these neuronal networks express 5-HT2Areceptors, the expression is higher in associative/limbic structures than in the motor ones. We show a topographical-dependent dissociation in the effects triggered by the 5HT2Aagonist TCB-2, which specifically increases the medialsubstantia nigra pars reticulataneuron activity and has a preferential action on mPF information processing through the striato-nigral direct pathway. These are very likely to be 5-HT2Areceptor-mediated effects that require mobilization of the endogenous 5-HT system. These findings provide evidence about the specific signature of 5-HT2Areceptors on the dynamic regulation of BG circuits.

Breaking the Cycle of Heart Failure With Preserved Ejection Fraction and Atrial Fibrillation
Authors: Țica Otilia , Khamboo Waseem , Kotecha Dipak
Published: November 2022

Heart failure with preserved ejection fraction (HFpEF) and AF are two common cardiovascular conditions that are inextricably linked to each other’s development and progression, often in multimorbid patients. Current management is often directed to specific components of each disease without considering their joint impact on diagnosis, treatment and prognosis. The result for patients is suboptimal on all three levels, restricting clinicians from preventing major adverse events, including death, which occurs in 20% of patients at 2 years and in 45% at 4 years. New trial evidence and reanalysis of prior trials are providing a glimmer of hope that adverse outcomes can be reduced in those with concurrent HFpEF and AF. This will require a restructuring of care to integrate heart failure and AF teams, alongside those that manage comorbidities. Parallel commencement and non-sequential uptitration of therapeutics across different domains will be vital to ensure that all patients benefit at a personal level, based on their own needs and priorities.

Introducción. La influencia del comercio electrónico (CE) sobre las decisiones de las personas en la compra de alimentos, ha sido relevante durante la pandemia por COVID-19. En Costa Rica no se dispone de información sobre la forma en que este medio ha modificado las conductas de compra y consumo de alimentos en las familias costarricenses durante esta emergencia sanitaria. Objetivo. Analizar cambios en los patrones de compra y consumo de alimentos de los costarricenses que fueron influenciados durante la pandemia por el CE. Materiales y métodos. En junio de 2021 se ejecutó una encuesta en línea con la metodología de bola de nieve en diferentes grupos de redes sociales de Costa Rica. Se utilizó modelación por ecuaciones estructurales para establecer las causas asociadas con variables endógenas (confianza, conveniencia, impulsos hedónicos) y exógenas (nivel socioeconómico, decisiones de compra por COVID-19) que delinearon los cambios en los hábitos de compra. Se revisaron los estímulos generados desde CE que influyeron sobre estas decisiones de compra según el grupo específico de alimentos. Resultados. Se encontró una fuerte causalidad desde la variable latente conveniencia (β=0,89; p<0,01), para la compra de alimentos por CE, además de poco impacto (β=-0,35; p<0,01) en los hábitos de consumo de alimentos, generado por las medidas definidas para atender la pandemia. Las medidas sanitarias decretadas por las autoridades evidenciaron causalidad en la respuesta general del consumidor de alimentos por CE (NORM_1<0,8; p<0,01), la cual fue baja si se compara su valor estimado con otros motivadores en las decisiones de compra como la conveniencia por las mejoras en la calidad de vida (CO1≅0,8; p<0,01), o incluso la confianza por el compromiso de calidad ofrecido por el sitio web (CF3≅0,6; p<0,01). Conclusiones. La pandemia promovió una mejor percepción del consumidor respecto a situaciones ventajosas de emplear CE para realizar la compra de alimentos.
GLP1-receptor-agonisták a 2-es típusú diabetes vércukorcsökkentő kezelésében

A glükagonszerű peptid-1 receptorának agonistái napjainkban a 2-es típusú
diabetes vércukorcsökkentő kezelésének meghatározó készítményei. Mára
kikristályosodtak adásuk lehetőségei: a fel- (step-up) és a leépítő (step-down),
vagy elterjedt új keletű kifejezéssel, a deeszkalációs antidiabetikumkezelésben
való részvételük, a már hozzáférhető oralis változatnak a parenteralis
készítményformával szemben mutatkozó előnyei és potenciális hátrányai, valamint
a bázisinzulinnal kombinált, fix összetételű változataik lehetséges
differenciálási lehetőségei. E kérdéseket tekinti át munkánk, de kitér a
gyógyszercsoporttal kapcsolatos újabb kutatásokra, a fejlesztés alatt álló új,
részben kombinációs készítményekre is. Felhívja a figyelmet e csoport képviselői
– elsősorban hosszú hatású származékai − korai alkalmazásának jelentőségére,
cardiorenalis védőhatására és a még szélesebb körű használatuk érdekében
szükséges folyamatos orvosszakmai tájékoztatás, valamint betegedukáció
fontosságára. Orv Hetil. 2022; 163(29): 1144–1151.
'Rainbow plague' or 'rainbow allies'?
Authors: Baran Dominika
Published: November 2022

The anti-genderism register, which demonises the LGBTQ+ community as promoters of so-called 'gender ideology', has spread in recent decades across right wing populist discourses around the world. In Poland, it is an important resource in right wing constructions of national identity, which appeal to a historicised account of Poland as the guardian of European Christianity. However, there is also a counternarrative that envisions Poland as a progressive member of the European Union with secular politics and respect for diversity in all its forms. In this context, the Polish lexeme tecza 'rainbow' is a floating signifier whose meanings are struggled over by opposing discourses of LGBTQ+ rights and their place in Polish public life. Drawing on an analysis of 521 texts from five media outlet types on the right and left wing sides of the political spectrum, this article examines the contestation of tecza as a site where the very meaning of present-day Polishness is discursively negotiated.Rejestr antygenderyzmu, ktory demonizuje spolecznosc LGBTQ+ jako promotorow tak zwanej ,,ideologii gender", w ostatnich dziesiecioleciach rozprzestrzenil sie w prawicowych dyskursach populistycznych na calym swiecie. W Polsce stanowi on istotny element prawicowych konstrukcji tozsamosci narodowej, odwolujacych sie do uhistorycznionego ujecia Polski, postrzeganej jako straznika europejskiego chrzescijanstwa. Istnieje jednak kontrnarracja, prezentujaca Polske jako postepowego czlonka Unii Europejskiej, jako kraj zdolny do prowadzenia swieckiej polityki oraz poszanowania dla roznorodnosci we wszelkich jej przejawach. W takim kontekscie polski leksem ,,tecza" jest ,,plynna znaczaca", o ktorej rozumienie walcza przeciwstawne dyskursy praw LGBTQ+ i ich miejsca w polskim zyciu publicznym. W oparciu o analize 521 tekstow z pieciu rodzajow mediow, zarowno z prawicowej jak i lewicowej strony spektrum politycznego, niniejszy artykul analizuje kontestacje sensu ,,teczy" jako miejsca, w ktorym dyskursywnie negocjowane jest samo znaczenie wspolczesnej polskosci.

Published: November 2022

This study aims to characterize and investigate steel slag for the removal of its persistent organic pollutants (measured as COD) from pulp mill wastewater. Steel slag and its NaOH-modified states were characterized by Fourier-transform infrared spectroscopy (FT-IR), Brunauer-Emmett-Teller (BET) surface area analysis, Barrett-Joyner-Halenda (BJH) pore size, and volume analysis. Batch adsorption experiments were conducted to investigate the COD adsorption of slag-based adsorbents. The modification of NaOH was found to improve the COD adsorption capacity (by 1.5 times) of steel slag by generating hydroxyl and carboxyl groups and enlarging the specific surface area and pore size in the steel slag particles. In batch experiments, the suitable conditions for COD adsorption on NS (steel slag) and MS20 (2 M NaOH-modified steel slag) were determined to be pH 6 - 8, contact time 90 minutes, and adsorbent dosage 20 g/L. Langmuir and Freundlich adsorption isotherm models satisfactorily described the adsorption of COD on both NS and MS20 with a good correlation. According to the Langmuir isotherm, the maximum COD adsorption capacity of NS and MS20 were 5.16 and 6.87 mg/g, respectively. Column experiments demonstrated that NS and MS20 had promising potential for COD treatment in pulp mill effluent. According to the column results, 20 g of NS or MS20 was able to keep 300 mL or 525 mL of 125 mg/L COD wastewater, respectively, reaching the threshold of the National Technical Regulation on Industrial Wastewater QCVN 40:2021/BTNMT.

Published: November 2022

Pristine graphene and graphene derivatives have been investigated with the density functional theory (DFT). The calculations consist of structural optimization, density of states (DOS), projected density of states (PDOS) based on orthorhombic 4-atom unit cell. The obtained results are in good agreement with the experimental data. The highest deviations from the experiment are 0.35 % and 0.28 % for the lattice constant and bond length, respectively. In addition, the results of DOS, and PDOS have shed light on electronic properties of graphene. The functionalization of graphene leads to distortion of graphene sheet. New states around the Fermi level of graphene derivatives are mainly composed of 2p orbitals of carbon and oxygen atoms. Besides, structural and electronic properties of graphene and derivatives obtained from the 4-atom orthorhombic unit cell are in line with those from the traditional hexagonal 2-atom unit cell in the previous works. This result proved the reliability of the constructed orthorhombic 4-atom unit cell of graphene.

Viet Nam’s coastline faces many natural and human-induced threats, such as erosion, floods, sea-level changes, pollution and saltwater intrusion. Low lying deltas, such as the Mekong Delta and the Red River Delta of Viet Nam are frequently subjected to such threats. The present study investigated the degradation of mangrove forests and changes in shoreline along the coast of Ben Tre. For this purpose, we used spectral indices, such as the normalized difference vegetation index (NDVI) for mapping mangrove vegetation and the normalized difference water index (NDWI) for estimating shoreline changes. The possibilities, advantages and limitations of coastal vegetation, such as mangroves, casuarina and pandanus, as a bioshield for shoreline protection in Ben Tre coast of the Vietnamese Mekong Delta (VMD) were also discussed. The results show that coastal areas covered with newly planted mangroves showed reduced or no erosion. Currently, several hard structures have been used for short-term protection from coastal erosion in Ben Tre. For long-term coastal protection, the present study suggested an ecosystem-based adaptation using bioshield for Ben Tre coast. A combination of hard structures reinforced with bioshield is recommended for long-term and sustainable coastal protection in Ben Tre.
Information Policy of Local Authority in Internet as a Factor of Societal Regulation: Sociological Analysis
Authors:   Tula State University, Gogoleva Elena
Published: November 2022

Influence of information on the social management is constantly increasing. Information policy in Russian local self-government system is a given of maintaining significant social relationships in municipality and a factor of the development of civil society. The interactive information policy contributes to the preservation of sensed-presence effect of local community in the public area, and to the setting new goals of the municipal development. Research problem is the lack of actual sociological facts about the abilities and limitations of organization and implementation of local information policy that are adequate to the needs of the local community. The goal of the sociological research is to define and evaluate content and functional characteristics of the local authoritys work on keeping feedback with local community in the space of Internet. The methodological basis of the sociological research is the system approach under which local self-government analyzed as the open system in which interaction between social agents is supported through information. Discourse analysis as a method of qualitative empirical research has made it possible to identify the specifics of information representation by local governments on the Internet in the process of creating and maintaining an information and communication structure of social interaction. On the basis of the data obtained, insufficient information openness, interactivity and usability of the Internet sites of local governments were established, which complicates the development of intergroup ties and relations. The author focuses on the declarative realization of information policy in the sites that focuses on the one-sided vector of information and the dominance of the subject of management. The functionality of the Internet-sites is limited to the execution of ideological and legal functions while the local authorities do not pay the attention to the forming identity of local community members and their involvement in local government. These facts hinder societal regulation in the municipality that shows in unstable interaction in the process of state-public relations.

Published: November 2022

Resumo: Introdução: Os estudantes de Medicina vivem experiências de adoecimento e dificuldades em saúde mental frequentes e, muitas vezes, graves. Essas experiências se acentuaram durante a pandemia de doença por coronavírus (Covid-19). Nesse contexto, o treinamento em atenção plena e regulação emocional pode ser uma ferramenta útil de promoção da saúde mental nessa população. Relato de Experiência: Com o objetivo de disponibilizar esse treinamento para os estudantes de Medicina de uma instituição de ensino de Minas Gerais, foi ofertada uma disciplina sobre atenção plena e equilíbrio emocional. Ofereceu-se essa disciplina entre setembro e dezembro de 2020, com 13 aulas síncronas remotas semanais, com duas horas de duração, para 16 estudantes. Após o transcurso da disciplina, aplicou-se um questionário on-line com perguntas abertas e fechadas com três seções: informações sociodemográficas, avaliação da disciplina baseada na Escala de Satisfação com a Experiência Acadêmica (ESEA) e avaliação de impactos no bem-estar subjetivo por meio do Questionário de Saúde Geral 12 (General Health Questionnaire 12 - GHQ-12). Treze estudantes responderam ao questionário da pesquisa. A disciplina foi considerada satisfatória pela maioria dos estudantes em todos os itens avaliados. Nos 12 aspectos de saúde mental pesquisados, a concordância com os impactos positivos da disciplina variou de oito a 12 respondentes. Discussão: Em consonância com as revisões sistemáticas sobre o tema, a disciplina “Atenção plena e equilíbrio emocional” parece ter impactado de forma positiva a saúde mental, a sociabilidade e a autoimagem dos estudantes. Todos os aspectos pedagógicos avaliados foram considerados satisfatórios por mais de 80% dos participantes, com exceção dos que avaliavam especificamente o formato remoto. O caráter optativo da oferta da disciplina pode ter contribuído de forma relevante para esse resultado. Conclusão: Considerando as particularidades do contexto pandêmico, foi possível disponibilizar uma proposta original de disciplina sobre atenção plena e equilíbrio emocional positivamente avaliada pelos estudantes. Novas pesquisas são necessárias para confirmar a associação entre a participação na disciplina e a promoção do bem-estar mental.
