Authors: Manullang Nursarinah , Fathiah Fathiah , Ikhsan Muhammad
Published: November 2024

The introductory electrical energy course is one of the courses that applies learning using practical methods. In the introductory electrical energy course, there is material about electrical power. Based on observations, it is known that students need more learning media in the form of modules in the electrical power practicum, which causes a lack of interest and low understanding of student learning. Based on these problems, a learning medium in the form of a practicum module was developed to complement practicum learning and is expected to increase students' interest in and understanding of learning. The electrical power practicum module was developed using research and development methods. The researcher's research instrument was a media expert and material expert validation sheet to test the feasibility of the practicum module to be applied in the Electrical Power Practicum. The validation results of media and material experts prove that the electrical power practicum module is very feasible regarding media and material. Based on the percentage of scores obtained from media experts, namely 81.66%, material experts obtained a score of 88.57%, which is included in the very suitable category to be applied in the Basic Electrical Energy course.

Published: November 2024

The level of electrical energy demand in an area reflects the welfare of that community. The greater the use of electrical energy, the higher the community's standard of living, followed by the public's critical attitude towards everything that happens and influences lives, including electricity services. Generally, a network's reliability level can be seen from the size of the SAIDI and SAIFI values on the PLN (state electricity company) side. The calculation and reliability analysis results of the Lhokseumawe ULP above show that the total SAIFI index value is 2.68 times/year. The SAIFI Rayon Lhokseumawe reliability index is categorized as reliable because its value does not exceed the standard set by PLN in SPLN 68-2 of 1986, namely 3.2 times/year. The total value of the SAIDI index is 45.30 hours/year. The Lhokseumawe Rayon SAIDI reliability index is categorized as unreliable because its value exceeds the standard set by PLN in SPLN 68-2 of 1986, namely 21 hours/year. There are certainly differences in infrastructure, electrical equipment, and number of customers in 1986 compared to current years; this has a different influence on electricity reliability values such as SAIDI and SAIFI.

Authors: Garg Rishi , Sinha Rajesh , Maheshwari Sonali , Sharma Shantanu , Mehra Sunil
Published: November 2024

Pre-conception care pertains to any preventive, promotive, and curative interventions for improving the health outcomes of women. Contrary to the growing burden of intergenerational transmission of chronic diseases, women lacked awareness and access to services for pre-conception care. Considering this, we conducted a cross-sectional study to assess the awareness, perceptions, and practices of pre-conception care among women from young and middle-aged groups in the Morena district of Madhya Pradesh. It was a cross-sectional study conducted with 383 women of reproductive age group (15-40 years) using a structured and pre-validated quantitative questionnaire. Out of 383 women, 171 belonged to the younger age group (15-24 years) and 212 to the middle-aged group (25-40 years). More than 50% of women had not heard of pre-conception care, and more than 90% of women in both groups had low dietary diversity. Middle-aged women had higher pre-conception care compared to younger women (βeta coefficient (95% Confidence Interval); p-value: 0.49 (0.03, 0.95); 0.03).

E. turnerae, T arnaldoi e E. weberi, antes conhecidas do norte da América do Sul e no Caribe, têm seus limites meridionais estendidos até 22° S.
Comparative study on the efficiency of two plankton nets for the quantitative estimation of appendicularians (Chordata, Tunicata)
Authors: Esnal Graciela Beatriz , Sankarankutty Cheruparambil , Gonzalez Beatriz Nora , Capitanio Fabiana Lía
Published: November 2024

Appendicularians collected from a coastal station located at 5°S and 36°W, northeast Brazil, were studied. Eight daytime and eight night samples were collected from the 0-10 m layer. Two samples were taken simultaneously using 53 pm and 200 pm mesh plankton nets. Oikopleura cornutogastra, O. dioica, O. longicauda, and O. rufescens were the main species present in the samples. The efficiency of both nets was compared for the quantitative estimation of these species. All the appendicularians were classified into three maturity stages: immature, intermediate, and mature. Their densities were compared using a randomized complete blocks ANOVA design with net level as the main plot. Only immature O. dioica were underestimated when a 200 pm mesh net was used (P=0). Immature individuals of the remaining species were equally captured by both nets (P>0.05). O. longicauda and, to a lesser extent. O. dioica, were the dominant species. All samples showed a high proportion of immature animals, indicating an active reproduction of all the species.
Temporal and spatial dynamics of nutrients and particulate suspended matter in Paranaguá Bay, PR, Brazil
Authors: Machado Eunice da Costa , Daniel Cesar Bolivar , Brandini Nilva , Queiroz Ricardo Luiz Vasconcellos de
Published: November 2024

In order to assess the seasonal and spatial variations on the trophic structure in the estuarine region of Bay of Paranaguá, 12 monthly sampling cruises were carried out between July/1994 - June/1995, at 9 selected stations along the major axis of the bay. Dissolved inorganic nutrients (nitrate, nitrite, ammonium, phosphate and silicate), dissolved oxygen, pH, transparency, temperature, salinity, seston, chlorophyll-a (Chl-a) and particulate organic carbon (POC) in both surface and bottom waters were evaluated. The bay exhibited a striking spatial and seasonal pattern for most of the studied parameters and, except for silicate, all nutrients showed a non-conservative behavior. This is probably due to the interactions between hydrodynamic processes and different mechanisms of loss and supply of these constituents, such as biological uptake, fresh-water input associated with the rainfall regime, sediment-water interactions and sewage discharge from the city of Paranaguá. In spite of the great spatial variability observed in nutrient and chlorophyll-a levels along the salinity gradient, acute eutrophication was not detected. As expected, dissolved inorganic nitrogen: phosphate ratios demonstrate that nitrogen is potentially more limiting for the pelagic production. Marked variations of POC:Chl.-a indicate the occurrence of temporal changes in the source of organic detritus for the pelagic system of the Bay of Paranaguá, with a greater contribution from detritus derived from the phytoplankton in summer.
Variação sazonal do fitoplâncton na zona de arrebentação da praia de Pontal do Sul (Paranaguá - Paraná)
Authors: Rezende Kátia Regina Vieira de , Brandini Frederico Pereira
Published: November 2024

A variação temporal da comunidade fitoplanctônica em um ponto fixo da praia de Pontal do Sul (Pontal do Paraná-PR) foi relacionada com as mudanças no padrão de circulação de massas d’água da região costeira adjacente e com as perturbações meteorológicas (frentes frias) que periodicamente invadem o local estudado. Amostras de fitoplâncton total e de rede foram coletadas na zona de arrebentação da praia de Pontal do Sul de abril de 1988 a julho de 1989 em intervalos semanais e mensais, respectivamente. O ponto de coleta está localizado em frente ao Centro de Estudos do Mar e apresenta características de uma praia semiprotegida pela proximidade com a Ilha do Mel. Fitoflagelados foram os organismos dominantes, com destaque para a fração de 3 a 6 pm. As diatomáceas foram abundantes durante o período quente e chuvoso do verão, mas algumas espécies apresentaram altas densidades em períodos isolados. Discute-se a ocorrência da espécie Asterionellopsis glacialis que apresentou picos esporádicos, associados com as alterações ambientais decorrentes da passagem de frentes frias. Skeletonema costatum foi dominante durante o verão, mas também apresentou um pico isolado no período de outono-invemo, indicando que outros fatores, além das altas temperaturas, são responsáveis pelo seu aparecimento. Cianofíceas e dinoflagelados foram abundantes no verão e silicoflagelados no inverno. O grupo das euglenofíceas não apresentou um padrão definido,mas foi ocasionalmente o responsável por densas manchas esverdeadas na areia da praia. Apesar de ser um fenômeno freqüente na região, nenhum estudo específico foi realizado a este respeito.
Tidal characteristics and a numerical model for the m2 tide at the Estuarine Complex of the Bay of Paranaguá, Paraná, Brazil
Authors: Marone Eduardo , Jamiyanaa Dashdorj
Published: November 2024

The tides at the estuarine complex of the Bay of Paranaguá (ECBP) were investigated using stochastic analysis and numerical modelling. Sea level records from six tidal locations were analysed using harmonic analysis, and showed that M2 is the dominant tide. A numerical model was implemented based on the dominance of the M2 component. The model uses finite differences to represent the hydrodynamic equations, with an explicit resolution scheme and non-slip contour conditions. The tidal regime is semidiurnal with pronounced diurnal inequalities. The overtides, the even, and the shallow water constituents are important, indicating strong non-linear interactions, which allow the formation of up to six high and low tides per day during neap cycles. This higher frequency oscillation is ascribed to double high and double low water effects. Tidal ranges increase from the mouth to the end of the complex, by 160%. Tidal phases and ranges indicate that the tidal wave propagates in a mixed form. The model confirms the mixed tidal wave regime.
Counting and measuring living protozooplankton using a video enhanced microscope and a new microplankton concentration device
Authors: Cordeiro Tarcisio A , Uhlig Gotram , Brandini Frederico P
Published: November 2024

The microscopic and fragile nature of the protozoans is the major barrier to their study. The most traditional taxonomic literature on protozoans is illustrated with stained specimens, which sometimes do not resemble the living cells. These artifacts are satisfactory for taxonomy purposes, but not for ecological analysis. Staining methods cause the cells to shrink and also cell wall disruption. This work describes a combination of the Utermohl method and a new concentration device plus video microscopy for analysing living protozoans. The procedure seems to be an accurate and reliable way to assess protozooplankton biomass.
First record of Magelonidae, magelona riojai Jones, 1963 (Polychaeta) in coastal waters of Argentina
Authors: Elías Rodolfo , Bremec Claudia Silva
Published: November 2024

Magelona riojai Jones, 1963 (Magelonidae) is reported for the first time in Argentine waters. The specimens were collected during a benthic sampling program developed in Mar del Plata city coastal area (38°S), aimed at determining the structure of subtidal soft-bottom macrobenthic communities and their relationship to sewage effluent. This is also the first report of the family in Argentina, and extends its southern range of distribution from 30° to 38°S. The specimens were recorded in sandy bottoms with low organic content, between 6.5 to 12.5 m depth, in front of a sewage effluent of Mar del Plata city.
Desembarque da pesca costeira em Cananéia (São Paulo), Brasil, durante 1995 e 1996
Authors: Mendonça Jocemar Tomasino , Katsuragawa Mario
Published: November 2024

A pesca costeira na região de Cananéia, costa sul do Estado de São Paulo, Brasil, foi analisada a partir de dados de esforço, captura e metodologia de coleta, observados entre 1995 e 1996. O método tradicional de coleta de dados foi aperfeiçoado, a fim de obter informações de melhor qualidade dos pescadores. O camarão-sete-barbas (Xiphopenaeus kroyeri) foi o principal recurso pesqueiro, envolvendo 75% dos barcos arrasteiros da região. As capturas mais expressivas ocorreram nos primeiros meses de cada ano, declinando gradualmente ao longo dos anos. Os resultados indicaram que a pesca do camarão-sete-barbas ocorre mais intensamente durante o período do recrutamento da espécie, de janeiro a março. Outra importante pescaria da região é a que utiliza redes de emalhar, capturando principalmente a pescada-foguete (Macrodon ancylodon) no primeiro semestre, a corvina (Micropogonias fumieri) nos meses de primavera e os cações na segunda metade do segundo semestre. A salteira (Oligoplites saliens) e a betara (Menticirrhus americanus) foram importantes componentes das capturas com redes de emalhar. A variação das capturas ocorreu possivelmente devido às condições estruturais dos barcos e a habilidade da tripulação em ambas as artes de pesca.

Published: November 2024

The year round changes in morphology of four southern Brazil sandy beaches was quantitatively studied. The sea water inside the breaker zone, although presenting a low turnover rate characteristic of dissipative beaches, shows in its salinity the strong influence o f continental shelf water on nearshore water. Two types of beach profiles (undulation and swell profiles) were described which were distinctly associated with the interaction between wave climate and local winds. Different beach profiles along the coastline were registered during the same period, as a reflection of different sand grain parameters. The principal feature of the southern Brazil high energy sandy beaches was the strongly seasonal pattern of climate, morphology of beach profile and sediment parameters.

The paper examined the spatial distribution and patronage pattern of recreational facilities in the University of Ilorin (UNILORIN). The study used primary data, which were obtained through a structured questionnaire administered randomly to the selected academic and non - teaching staff of UNILORIN. Geo-spatial data on the locations of the recreational facilities were collected and analyzed with the use of Global Positioning System (GPS) and Nearest Neighbour Analysis respectively. Pearson’s Product Moment Correlation Analysis was employed to examine the relationship between residence and patronage of recreational facilities at 5% level of significance. With an Rn value of 1.47 (p=0.000378), the distribution of recreational facilities in UNILORIN was dispersed. The paper also observed that, there was no significant relationship between staff place of residence and their patronage of recreational facilities (r = 0.05, p value = 0.474). The study established that health benefits and pleasure with Enhancing Factor Index of 2.58 and 2.46 respectively, were the major enhancing factors of recreational facilities patronage. The paper concluded that locations of recreational facilities are far from each other and by implication the distribution is nor regular. The paper therefore recommended that future recreational facilities should be evenly distributed so as to foster more patronage by staff members of University of Ilorin.
A classe média em crise: vulnerabilidade socioeconômica diante da tecnologia

Published: November 2024

Por ter começado há muito tempo, por ser uma economia mais dinâmica, por investir mais em avanços tecnológicos, a situação nos USA, que será chamada “Classe Média em Crise” se tornou dramática e complexa. No Brasil, o mesmo pode acontecer em breve. A “internet comercial” trouxe muitas novidades, como “monetização”, “cobrança por serviços”, “serviços patrocinados”, “pagamento pelo tráfego” e outras, que iriam evoluir rapidamente, trazendo novas soluções e problemas totalmente novos. O objetivo é discutir os efeitos da Internet para a sociedade, principalmente, com a classe no Brasil. O que começou com problemas econômicos ligados à queda na renda, devido ao desemprego e subemprego, precarizando a Classe Média Precária vagarosamente evoluiu para problemas relacionados com o abuso no uso das redes sociais, solidão dos jovens e problemas psicológicos dos pais e jovens, e infelizmente, termina com o aumento da taxa de suicídio dos jovens de 15 a 24 anos. Na nossa opinião a internet precisa mudar ou deixar de ser como ela é. E as consequências do rápido avanço tecnológico precisa ser equacionado antes que os fatos sejam consumados, como o desemprego, subemprego, depressão e ansiedade de Pais e Filhos, e por fim, precisamos deter esse avanço das tentativas de suicídio entre os jovens. Portanto, “e agora? O que temos de fazer?”.
O princípio de acumulação do capital e a regulamentação da educação a distância no Brasil: uma análise a partir do materialismo histórico
Authors: Dalpicolo André Christian , Mill Daniel Ribeiro Silva
Published: November 2024

O objetivo deste artigo é examinar a relação existente entre o princípio de acumulação do capital e a regulamentação da EaD no Brasil. Para tanto, faz-se necessário desenvolver uma linha de raciocínio que se desdobrará em dois planos diferentes. O primeiro assinalará a forma pela qual o princípio de acumulação do capital representa a causa econômica que regulamenta a Lei n° 9.394/1996 no território brasileiro, visto que deseja aumentar a velocidade da equação marxiana D – M – D’ (Dinheiro/ Mercadoria/ Dinheiro-Lucro). De certo modo, é preciso informar que esse aumento é obtido mediante a exploração contínua de um tipo de mercadoria (a força de trabalho) através do fenômeno da mais-valia. Já o segundo especificará a maneira pela qual a educação brasileira está abandonando paulatinamente o pensamento crítico em detrimento de certos conhecimentos técnicos e resultado desse abandono é a consolidação da intitulada, ou melhor, de uma universidade que procura tão somente dotar o capital humano das competências e habilidades primordiais para a melhoria de empregabilidade. Convém observar que o pressuposto metodológico-teórico desta pesquisa é o materialismo histórico, já que este último é capaz de evidenciar a lei econômica que fundamenta as mudanças primordiais da educação brasileira desde 1996.

Objetivou-se com este trabalho avaliar o potencial das Redes Neurais Artificiais (RNAs) para predição da produtividade do feijão-caupi e determinar os componentes produtivos de maior importância relativa para esse fim. Foi instalado um ensaio de uniformidade, na safra de verão-outono do semiárido mineiro, com a cultivar BRS Imponente. Cada metro de fileira de plantas foi considerado como uma unidade básica (UB), perfazendo 195 UB amostradas para o estudo. Foram avaliados o estande final de plantas, número de vagens por planta, número de grãos por vagem e a produtividade de grãos. Os dados foram submetidos ao modelo neural do tipo perceptron de multicamadas (MLP). Dez arquiteturas de rede foram treinadas por 100 vezes, selecionando-se, ao final do treinamento, aquela com menor erro quadrático médio para os dados de validação. A arquitetura de rede com três neurônios na camada intermediária forneceu os melhores resultados, apresentando alta precisão entre os valores reais e preditos, garantindo o potencial de generalização do modelo. Os caracteres produtivos de maior contribuição relativa neste estudo são o número de vagens por planta (VP) e o estande final (EF), não sendo recomendada a exclusão de nenhuma das características estudadas para a predição. As RNAs do tipo Perceptron de Múltiplas Camadas (MLP) e os componentes produtivos asseguram a predição da produtividade do feijão-caupi com uma eficiência de 94%.

One-step soaking strategy toward mechanical double-network hydrogel
Authors: Zhu Wantong
Published: November 2024

Double-network (DN) hydrogels, which comprise noncovalent interacting networks, are highly sought after due to their controlled compositions and environmental friendliness. However, the complex preparation methods hinder the application of these hydrogels. In this study, we present a simple and feasible approach for fabricating hybrid PAA-CS DN hydrogels by post-treating the PAA-CS composite hydrogels with CuSO4 solutions to induce the formation of physical networks through CS chain entanglement. The composite hydrogel, composed of chitosan (CS) and polyacrylic acid (PAA), readily transforms into a DN hydrogel after soaking in a CuSO4 solution, thanks to in situ formation of chain entanglements, hydrogen bonds, and ionic coordination. The resulting hybrid DN hydrogels exhibit porous networks, high tensile strength, and exceptional toughness. This facile but effective soaking method can be universally applied to fabricate mechanically robust hydrogels, modulate noncovalent interactions, and broaden their potential applications.

Authors: Lv Qianying , Chen Zhixing
Published: November 2024

Falling In reveals the director's bold and avant-garde style in many ways.Tasim Sing has etched his personal mark on the film in an extremely thorough manner. As per the formula, the imaginary world constructed by the human brain overlaps with the real world to create the most bizarre and uninhibited imaginative space. Bright images also continue in the film. The film features a visual masterpiece, but the visual feast it presents is still different from the so-called commercial blockbuster scenes, and it is as different as one is a realistic oil painting with thick colour, and the other is a colourful surrealist watercolour.
