Authors: Dos Santos Sávio Barbosa , Feitosa Ailton 
Published: May 2022

O presente estudo analisou a influência dos fenômenos EL NIÑO e LA NIÑA na dinâmica de uso e ocupação do solo no município de Palmeira dos Índios/AL. Foram analisados dados climáticos, de produção e dados demográficos, com vista a análise dos impactos desses fenômenos no clima do Agreste alagoano no período de 1950 a 2020. Assim, foi possível relacionar a atuação desses fenômenos EL NIÑO e LA NIÑA na produção, uso, ocupação e permanência da população no campo. Incialmente foi possível identificar a dinâmica populacional do município, que era predominantemente rural até meados dos anos 1980. A partir de então, verificou-se uma redução expressiva de 90,3% do total da população do município, para 47,1%. Este resultado foi uma consequência de 27 anos sob a influência do fenômeno EL NIÑO, cujo maior impacto observado foi sobre o ritmo e o volume das precipitações, ocasionando assim períodos prolongados de secas. Dessa forma verificou-se também a redução na produção da pecuária na ordem de 94,9% no total da produção, que na década 1950 foi de 140.549 toneladas e caiu para 7.206 toneladas nos anos 1980. Assim como, foi observado uma redução das áreas de cultivos que foram abandonadas pela falta de chuvas. Palavras-chave: Semiárido, precipitação, agropecuária e demografia.

O balanço de radiação é uma variável muito importante para o entendimento da radiação, condições climáticas e de gestão dos recursos hídricos de uma região. Ao longo de muitos anos pesquisadores tem reunido esforços com o intuito de melhor entender o saldo de radiação de diferentes alvos a superfície. O maior desafio está na falta de monitoramento e observação de dados de radiação a superfície. A obtenção dessas informações é de alto custo e por esse motivo pouco desconhecido. Nesse sentido, desenvolver modelos que estimem saldo de radiação de forma precisa tem sido uma busca constante dos pesquisadores. Como o avanço tecnológico algumas alternativas têm surgido e se destacado em função da precisão de obtenção dos dados. Diante do exposto, o objetivo deste estudo é estimar o balanço de radiação com imagens de drone. Foi utilizado como metodologia o embasamento do SEBAL- Surface Energy Balance for Land. Os resultados obtidos mostram que a estimativa do saldo de radiação com drones é promissora, uma vez que as informações obtidas estão bastante coerentes com dados observados e já publicados em artigos científicos. Ainda foi possível mostrar que existe uma ótima relação do albedo a superfície com o saldo de radiação. Essa informação é importante quando se deseja disponibilizar modelos de simples utilização para a gestão dos recursos hídricos e agricultura de precisão. Radiation balance with imagens captured with Drones A B S T R A C TThe radiation balance is a very important variable for understanding radiation, climatic conditions, and the management of water resources in a region. Over many years, researchers have gathered efforts to better understand the radiation balance of different targets on the surface. The biggest challenge is the lack of monitoring and observation of surface radiation data. Obtaining this information is expensive and for this reason little unknown. In this sense, developing models that accurately estimate the radiation balance has been a constant search for researchers. As the technological advance, some alternatives have emerged and stood out due to the precision of obtaining the data. Given the above, the objective of this study is to estimate the radiation balance with drone images. The basis of the SEBAL- Surface Energy Balance for Land was used as a methodology. The results obtained show that the estimate of the radiation balance with drones is promising, since the information obtained is quite consistent with observed data and already published in scientific articles. It was still possible to show that there is an excellent relationship between the surface albedo and the net radiation. This information is important when you want to provide simple-to-use models for the management of water resources and precision agriculture.Keywords: drone, radiation balance, remote sensing.

Este artigo tem como objetivo mapear e analisar a dinâmica de uso e ocupação da terra da bacia hidrográfica da área de influência direta do reservatório da UHE Espora, localizada entre os municípios de Aporé, Serranópolis e Itarumã, no sudoeste do estado de Goiás, em quatro períodos distintos (2003, 2008, 2013 e 2018). A abordagem metodológica teve enfoque na análise temporal do uso e cobertura da terra, com aplicação de técnicas de processamento e classificação computacional digital de imagem de satélites. Foram realizadas a identificação, a classificação e a quantificação dos tipos de uso e cobertura da terra. As classes de uso da terra estudadas foram: água, vegetação, pastagem e agricultura. Os resultados apontaram que, para o período de análise de 2003 a 2018, houve um aumento da área da classe de água, principalmente, pela construção do barramento do rio Corrente, e uma crescente expansão da área agrícola voltada à inserção da cana-de-açúcar no Cerrado brasileiro; contrapondo-se à expansão agrícola, ocorreu diminuição da vegetação nativa e da pastagem.Palavras-chave: bacia hidrográfica, sensoriamento remoto, Cerrado. Mapping the use and occupation of the basin of influence of the reservoir of the hydroelectric plant of Espora-GO A B S T R A C TThis paper aims to map and analyze the landscape dynamics of land use and occupation of the area under direct influence of the Espora Hydroelectric Plant, located between the municipalities of Aporé, Serranópolis and Itarumã, southwestern Goiás, in four distinct periods (2003, 2008, 2013 and 2018). The methodological approach focused on the temporal analysis of land use and cover, applying the techniques of Digital Image Processing through unsupervised classification. The identification, classification and quantification of land use and cover types were performed. The results showed that for the period of analysis from 2003 to 2018 there was an increase in the area of the water class, mainly due to the construction of the dam of the Corrente river and a growing expansion of the agricultural area aimed at the insertion of sugarcane in the brazilian Cerrado; counteracting the agricultural expansion, there was a decrease in native vegetation and pasture.Keywords: hydrographic basin, remote sensing, geographic information system.

Published: May 2022

A construção de barragens para geração de energia hidroelétrica causou alterações nas condições naturais dos setores Sub-médio e Baixo São Francisco, formando uma cascata de barragens e reservatórios ao longo do eixo principal do rio. O presente trabalho avaliou a carga de fósforo ortofosfato no baixo rio São Francisco AL/SE – Brasil, durante os anos de 2008, 2009 e 2010. A área estudada encontra-se a latitude 10°12’ S e longitude 36°49’ W, 80 km a montante da foz e 100 km a jusante da Usina Hidrelétrica de Xingó, área da ponte rodoferroviária entre os municípios de Porto Real do Colégio-AL e Propriá-SE. As amostras foram coletadas em uma estação próxima a ponte rodoferroviária entre as cidades de Propriá (SE) e Porto Real do Colégio (AL). Neste estudo o fósforo inorgânico dissolvido (PID) pode ser considerado baixo quando comparado com outros rios tropicais. Após a conclusão da cascata de barragens e a regulação do fluxo dos rios após 1995, as cargas específicas de PID diminuíram a níveis abaixo de rios tropicais que já possuíam cargas específicas mais baixas. A comparação das cargas específicas de PID do RSF com outros rios tropicais mostram que diferenças de gradiente, tamanho, cobertura vegetal e obras de engenharia tiveram efeitos diferentes sobre as cargas específicas de nutrientes.Palavras-chave: vazão; yield; ortofosfato. Analysis of the temporal variation of phosphorus load in the lower São Francisco River (AL/SE) A B S T R A C TThe construction of dams for hydroelectric power generation caused changes in the natural conditions of the Submedia and Baixo São Francisco sectors, forming a cascade of dams and reservoirs along the main axis of the river. The present work evaluated the load of phosphorus orthophosphate in the lower São Francisco River AL / SE - Brazil, during the years 2008, 2009 and 2010. The studied area is located at latitude 10 ° 12 'S and longitude 36 ° 49' W , 80 km upstream of the mouth and 100 km downstream of the Xingó Hydroelectric Plant, an area of the railroad bridge between the municipalities of Porto Real do Colégio-AL and Propriá-SE. How they were collected at a station near the railroad bridge between the cities of Propriá (SE) and Porto Real do Colégio (AL). In this study, dissolved inorganic phosphorus (PID) can be considered low when compared to other tropical rivers. After the completion of the cascade of dams and the regulation of river flow after 1995, specific PID loads decreased to levels below tropical rivers that already had lower specific loads. The comparison of RSF's PID loads with other rivers determined that difference in gradient, size, vegetation cover and engineering works have different effects on specific nutrient loads.Keywords: flow rate; yield; orthophosphate.

Characterizing Lithium-Mediated Nucleoside Transport by Human Concentrative Nucleoside Transporters 1 and 3 (hCNT1 and hCNT3)
Authors: Kanagala Bhavana 
Published: May 2022

The human concentrative nucleoside transporters (hCNTs) utilize coupling and movement of cations down their electrochemical gradient to mediate inward transport of nucleosides against their concentration gradient. Of the three hCNT family members, hCNT3 exhibits the broadest nucleoside selectivity and cation specificity, utilizing Na+, Li+, and H+ to drive nucleoside transport. Xenopus laevis oocytes were injected with hCNT1 and hCNT3 RNA transcripts and incubated for 48 hours to allow protein expression and localization to the plasma membrane. The two-electrode voltage clamp (TEVC) method was used to perform electrophysiological studies. Oocytes were voltage-clamped, and currents were measured in response to various cation conditions, addition of different nucleosides and changes in membrane potential. Voltage-dependence of hCNT1- and hCNT3-mediated uridine uptake and hCNT3-mediated nucleoside uptake-induced currents was determined using NaCl, ChCl and LiCl transport media. Li+ addition resulted in decreases in uptake of uridine both by hCNT1 and hCNT3. hCNT1 and hCNT3 exhibited similar trends in voltage-dependence of uridine transport; currents generated increased as potentials became more negative. It was shown that whereas Na+-coupled hCNT3 has broad nucleoside selectivity, Li+-coupled transport varied widely and was greatest for uridine, and least for thymidine (uridine > cytidine > guanosine > adenosine > inosine > thymidine). Our results indicate a possible role of the nucleoside nitrogenous base ring structure in the differential uptake of various nucleosides. Despite no significant role of Li+ in vivo, further understanding of hCNT3 interactions with this cation may lead to a better understanding it’s transport mechanism and assist in the future design and delivery of effective anti-cancer drugs and anti-viral nucleoside drugs.

Tourism as a ‘Moment of Being
Authors: Andrews Hazel 
Published: May 2022

The purpose of this article is to gather together a number of conceptual or theoretical points drawn from the wider social anthropological discourse on the nature of experience. It advances understandings of the anthropology of experience through the medium of tourism. In turn it also illuminates understandings of the nature of tourism experiences. The article is largely a theoretical piece that is illustrated with details drawn from an ethnographic study of two charter tourism resorts—Palmanova and Magaluf—in Mallorca. Therefore, in an attempt to elucidate more carefully what experience means, it draws on the discussions of ‘experience’ in the wider anthropological literature, most notably the existential anthropology of Michael Jackson (2005) and The nthropology of Experience (Turner and Bruner 1986), and makes links to the writings of Pierre Bourdieu on the concepts of ‘habitus’ and ‘field’, bringing them to bear on the subject of tourism.Keywords: experience, Erlebnis, Erfahrung, habitus, identity, Mallorca, tourists
The Primal Pentecostal Imagination
Authors: Gifford Paul 
Published: May 2022

This paper addresses the religious world-view that is characteristic of a great many of the Pentecostal Churches currently flourishing in Africa. In the opinionof the author, this world-view, which sees spiritual forces active in everyday events, is the greatest single reason for their success. This world-view comes in different but related forms, and three different forms currently found in Kenya are outlined here. These forms have obvious links to local religious thinking, but are also dependent for their expression on certain Western thinking. Finally it is claimed that this world-view, though in most studies of Pentecostalism virtually ignored, has important socio-political effects and merits serious discussion.

Authors: Qadir Mohammed Salim , A. Hussein Mohammed 
Published: May 2022

In recent years, the world witnessed a rapid growth in attacks on the internet which resulted in deficiencies in networks performances. The growth was in both quantity and versatility of the attacks. To cope with this, new detection techniques are required especially the ones that use Artificial Intelligence techniques such as machine learning based intrusion detection and prevention systems. Many machine learning models are used to deal with intrusion detection and each has its own pros and cons and this is where this paper falls in, performance analysis of different Machine Learning Models for Intrusion Detection Systems based on supervised machine learning algorithms. Using Python Scikit-Learn library KNN, Support Vector Machine, Naïve Bayes, Decision Tree, Random Forest, Stochastic Gradient Descent, Gradient Boosting and Ada Boosting classifiers were designed. Performance-wise analysis using Confusion Matrix metric carried out and comparisons between the classifiers were a due. As a case study Information Gain, Pearson and F-test feature selection techniques were used and the obtained results compared to models that use all the features. One unique outcome is that the Random Forest classifier achieves the best performance with an accuracy of 99.96% and an error margin of 0.038%, which supersedes other classifiers. Using 80% reduction in features and parameters extraction from the packet header rather than the workload, a big performance advantage is achieved, especially in online environments.
EFFECT OF ADSORPTION CONDITIONS ON THE REMOVAL OF LEAD (II) USING SEWAGE SLUDGE AS ADSORBENT MATERIAL
Authors: M. Fat’hi Ahmed , H. Ali Ahmed 
Published: May 2022

The introduction of more stringent legislation limiting the disposal and use of sewage sludge, combined with an increase in its production and the loss of previously recognized disposal routes, has sparked a search for alternate applications for sewage sludge. The conversion of sludge into adsorbents is one of the promising technologies give a more stable treatment of sludge. In a batch mode adsorption, adsorbent created by recycling sewage sludge was employed as a sustainable and low-cost material to remove pb (II) ions from manufactured polluted aqueous solutions. A laboratory test was done to determine the influence of a variety of operational parameters on Pb (II) adsorption, including the acidic function (pH), absorbent dosage, agitation speed, agitation period, and initial concentration at room temperature. The maximum removal efficiency was 88.2 % at optimum factors pH=4, agitation time =250 rpm, agitation time=180 min, adsorbent dose=1.5 g and initial concentration=50 (mg/l). In this way sewage sludge, which pollutes the environment and is costly to treat, may be disposed of in a useful and economic way to achieve the lowest pb (II) concentration level.
