Published: June 2023

Saat ini suplai energi listrik mayoritas menggunakan sumber energi fosil yang dapat habis dan menimbulkan polusi udara. Di Indonesia matahari bersinar cukup lama dan tidak akan habis, sehingga dapat dijadikan sebagai sumber energi alternatif dengan menggunakan teknologi panel surya untuk mengonversi energi cahaya menjadi energi listrik. Tegangan yang dihasilkan oleh panel surya cukup besar, sehingga perlu diturunkan menggunakan konverter DC-DC jenis buck converter. Energi listrik ini dapat disimpan menggunakan baterai. Untuk mempersingkat waktu pengisian, baterai dapat diisi dengan mode cepat. Salah satu jenis baterai yang tepat untuk pengisian mode cepat adalah Lithium-ion karena baterai jenis ini mampu menerima arus yang besar sebesar 1C atau setara dengan kapasitas baterai. Dengan menggunakan sumber panel surya, dihasilkan keluaran yang tidak konstan karena pengaruh suhu dan iradiasi matahari. Selain itu, untuk mencegah adanya pengisian berlebih pada fast charging battery ini, digunakan metode constant current (CC) dengan arus konstan sebesar 10 A dan constant voltage (CV) dengan tegangan konstan sebesar 14,4 V. Duty cycle driver PWM dikontrol menggunakan algoritma adaptive neuro fuzzy inference system (ANFIS) agar didapatkan respons yang lebih cepat untuk mencapai set point yang ditentukan. ANFIS merupakan kombinasi dari dua algoritma, yaitu artificial neural network (ANN) dan fuzzy inference system (FIS). ANFIS dapat memetakan nilai masukan menjadi nilai keluaran yang berasal dari kesimpulan FIS. Penelitian ini dilakukan secara simulasi. Hasil arus pengisian pada saat metode CC adalah 10,01 A dan akan berpindah dari metode CC ke CV pada saat SoC 85% serta tegangan mencapai 14,4 V. Kemudian, metode pengisian berubah menjadi CV dengan tegangan pengisian konstan sebesar 14,4 V. Jika dibandingkan dengan penelitian sebelumnya menggunakan kontrol fuzzy, waktu yang dibutuhkan ketika menggunakan kontrol ANFIS untuk mencapai set point adalah 3,2 ms, atau 2,3 ms lebih cepat. Kontrol ANFIS juga mampu mencapai set point dengan error lebih kecil dibandingkan dengan menggunakan kontrol fuzzy.

Background

The efficacy of immunosuppression in the management of immunoglobulin A (IgA) nephropathy remains highly controversial. The study was conducted to assess the effect of immunosuppression, compared with supportive care, in the real-world setting of IgA nephropathy.

Methods

A cohort of 3946 patients with IgA nephropathy, including 1973 new users of immunosuppressive agents and 1973 propensity score-matched recipients of supportive care, in a nationwide register data from January 2019 to May 2022 in China was analyzed. The primary outcome was a composite of 40% eGFR decrease of the baseline, kidney failure, and all-cause mortality. A Cox proportional hazard model was used to estimate the effects of immunosuppression on the composite outcomes and its components in the propensity score-matched cohort.

Results

Among 3946 individuals (mean [SD] age 36 [10] years, mean [SD] eGFR 85 [28] ml/min per 1.73 m2, and mean [SD] proteinuria 1.4 [1.7] g/24 hours), 396 primary composite outcome events were observed, of which 156 (8%) were in the immunosuppression group and 240 (12%) in the supportive care group. Compared with supportive care, immunosuppression treatment was associated with 40% lower risk of the primary outcome events (adjusted hazard ratio, 0.60; 95% confidence interval, 0.48 to 0.75). Comparable effect size was observed for glucocorticoid monotherapy and mycophenolate mofetil alone. In the prespecified subgroup analysis, the treatment effects of immunosuppression were consistent across ages, sexes, levels of proteinuria, and values of eGFR at baseline. Serious adverse events were more frequent in the immunosuppression group compared with the supportive care group.

Conclusions

Immunosuppressive therapy, compared with supportive care, was associated with a 40% lower risk of clinically important kidney outcomes in patients with IgA nephropathy.

Authors: Cardoso Hernández Itzel , Luna-Nemecio Josemanuel , Arribalzaga Tobón Víctor Manuel
Published: June 2023

Purpose: This contribution has two objectives: 1) to define in context, how the word téchnē and technology are linked to the Nahuatl notion in context; and 2) to characterize pre-hispanic environmental technologies in order to subjectively and materially project the practical utility of ancestral environmental technologies, precisely because they are capable of halting and even reversing the socio-environmental consequences derived from the current climate and ecosystem crisis.
Methodological design: From a historical-material perspective, an exploratory study of non-exhaustive and ontological-semantic nature is presented, whose strategy articulated and differentiated the Aristotelian etymon téchnē with the oldest one found in classical Nahuatl language. Previous criterion to characterize pre-Hispanic environmental technology and discuss its specific examples.
Results: The way in which Mesoamerican technologies were organized and implemented demonstrates that they achieved what is currently sought through sustainabilty over 2,000 years ago. The concept and characteristics defining and differentiating pre-Hispanic Nahuatl technology from the current techno-scientific-industrial paradigm were provided.
Toltecáyotl-amantecáyotl accounts for a productive and organizational system, sentient and alive, which guides the design of truly ecological new technologies. Among others, maize-milpa-chinampa technologies persist and are multidimensionally rewarding.
Research limitations: Currently, the complete number of technologies developed, their typology, and their locations are unknown. In Mexico, the disintegration of rural areas is accompanied by a loss of language, knowledge, and objects, which raises the difficulty of accessing ancestral technical-scientific memory.
Findings: Pre-hispanic technology is ecological, but not all current environmental and sustainable technologies are.

Abstract: Extraction of virgin coconut oil from coconut kernel is a major influential step for their commercialization. There are many extraction processes among which cold and hot extraction are conventional extraction processes. This paper focused on the design, construction and testing of a coconut extractor using fresh-dry process based on the low pressure oil extraction method production of virgin coconut oil to reduce the settling time of oil. Additionally, tests carried out on the machine were the oil quality test, yield comparison with conventional oil extractors and user experience. The drying motor of 1500hp was used for grinding and a 12V Dc motor converted to an AC drive was used for conveying to the extraction chamber. A heating element of 3KW was incorporated in the extraction chamber which was properly lagged to avoid heat losses. Results obtained showed that it takes 800 seconds of heating time at 70oC to actually extract oil from dried coconut under different parameter such as drying temperature, extraction time and moisture content. The production efficiency of machine was calculated to 69.5% and the machine performance was certified good. Oil quality was recorded at 0.46% free fatty acid. The designed extractor yielded approximately 20.7% of oil against 14.1% as recorded from traditional methods. User experience was rated an average of 8.47 on a maximum scale of 10 with ratings obtained from experts (7.5) experienced users (8.7) and non- experienced users (9.2). The production machine is novel for easier, safer and more economical extraction of virgin coconut oil over the traditional and conventional methods.

Concrete Structure by Using Carbon Nanotube and Its Use to Monitor Its Structural Health
Authors: Joshi Mukta
Published: June 2023

Abstract: Cementitious materials doped with carbon nanoparticles are robust materials that can convert stress into changes in electrical resistance. These properties encourage the development of spatially distributed sensors for structural health monitoring of concrete structures. However, very few applications of cement-based nanocomposite transducers to structural elements have been documented. Most applications are limited to measuring static reactions. CNTs could effectively arrest crack propagation, increase joint rigidity, and reduce deformation of concrete corbels between steel ribs. Higher aspect ratio CNTs could make a better contribution with their micro crack bridging effect. Microscopic analysis confirmed the adequate distribution and bridging of micro cracks by CNTs and delayed the propagation of macro cracks within the transition zones between aggregate and reinforced concrete

Published: June 2023

Introduction: Vascular access for hemodialysis (HD) is essential for the patient. Even though Arteriovenous fistula (AVF) is the preferred access, in certain age groups, the central venous catheter (CVC) may provide advantages. This study aims to investigate the quality of life related to vascular access.
Methods: Cross-sectional study including patients from a hospital, a home HD unit and a satellite hemodialysis center. Clinical data was collected from the patients, who went through a quality-of-life questionnaire SF12 and a Vascular Access Questionnaire (VAQ).
Results: 91 patients participated, mostly male (70%), with a mean age of 68.9 ± 16.2 years. AVF was the current vascular access in 60.4%, the rest used a CVC. Home HD was performed in 12.1% of patients and 76% started it via CVC. Regarding patients who have had both AVF and CVC, 58% prefer AVF and only 26.5% of current CVC carriers would have a new AVF, mostly due to fear of pain (52%). Most people (72.5%) reported having received sufficient information, with no differences between both accesses.
The SF12 results showed no differences between patients with AVF or CVC. Regarding the VAQ, patients with AVF were more satisfied with the social aspect (p = 0.036) and complications (p = 0.006).
Conclusion: Patients with AVF had better outcomes than those using CVC regarding complications and social aspects. These differences are not attributable to a worse overall quality of life status of CVC patients. Most patients with CVCs refuse to go through a new AVF for fear of puncture pain.
Discursos sobre o clima do nordeste brasileiro: educação, consensos e produção de sentidos
Authors: Dias de Azevedo Livia
Published: June 2023

A região Nordeste do Brasil se constitui como um acontecimento discursivo. Os sentidos históricos e geográficos atribuídos a esta região giram em torno, basicamente, da falta ou escassez das chuvas e da veiculada dependência política, tecnológica, cultural, educacional e financeira dos grandes centros da região Sudeste. Esses são discursos que circulam por diferentes espaços-tempos escolares, científicos e midiáticos. À vista disso, esta tese pretende compreender os efeitos de sentidos sobre o clima da região Nordeste do Brasil produzidos a partir de um conjunto de questões dissertativas das provas de Geografia dos exames vestibulares da Unicamp de 1987 a 2016, a partir dos aportes fornecidos pela Análise de Discurso franco-brasileira. Propomos a seguinte pergunta para conduzir as análises: qual o funcionamento discursivo do tema clima do Nordeste em questões de Geografia do vestibular da Universidade Estadual de Campinas (Unicamp )? Ou dito de outra forma: quais os efeitos de sentidos produzidos por essas questões quando relacionadas a outras textualidades? A estrutura teórico­metodológica se sustenta, basicamente, em Michel Pêcheux, Eni Orlandi, Jean Jacques Courtine, Suzy Lagazzi, dentre outros. Durval Muniz Albuquerque Júnior e Iná de Castro foram importantes interlocutores, na História e na Geografia, respectivamente. Através das análises foi possível identificar que a noção de "falta" atravessa todas as questões sobre a região Nordeste. Falta tudo ou quase tudo: água, comida, saúde, trabalho, educação, civilização, desenvolvimento, tecnologia.

Published: June 2023

This study aims to determine the ability of shrimp waste processing with several combinations of processing such as soaking using husk ash water filtrate, steaming and fermentation using the Trichoderma viridae fungus, as well as to determine the optimal level and level of using processed shrimp flour to replace fish meal in broiler chicken rations. . The study was conducted experimentally using a completely randomized design method consisting of 5 treatments and 4 replications. The treatment given was replacing fish meal with processed shrimp waste flour which consisted of P0 = 0% processed shrimp waste flour, P1 = 25% processed shrimp waste flour, P2 = 50% processed shrimp waste flour, P3 = 75% processed shrimp waste flour. and R4 100% processed shrimp waste flour. The data obtained were tabulated using the Microsoft Excel program, then analyzed using analysis of variance (ANOVA), if there were differences, then the Multiple Distance Test (Duncan's). The observed variables consisted of changes in the nutritional content of shrimp waste before and after processing, feed consumption, body weight gain and feed conversion in broiler chickens. The results of this study indicate a decrease in the nutritional content of processed shrimp waste. The replacement of fish meal with processed shrimp waste in broiler chicken rations had a very significant effect (P<0.01) on consumption and body weight gain, but had no effect (P>0.05) on feed conversion value. Based on the results of the study, it can be concluded that the processing of shrimp waste through several processes has not been able to improve the nutritional content of shrimp waste. The use of processed shrimp waste flour can be used up to 50% level as a substitute for fish meal in broiler chicken rations. Suggestions that can be given are the length of processing time from shrimp waste can be reduced in order to minimize factors that can damage or reduce the nutrition of shrimp waste.

Para tanto, parte da metodologia do percurso analítico-interpretativo proposto por Henriete Karam (2017), bem como do levantamento bibliográfico e legislativo. Assim, o trabalho analisa a obra literária que retrata o poder estatal ilimitado através da violência; e posteriormente, reflete a necessidade de limitação desse poder, problematizando a contrapelo dos direitos e garantias presente no Estado Democrático de Direito. O estudo baseia-se no garantismo jurídico para compreender que um Estado só será legítimo se conseguir concretizar os direitos fundamentais previstos formalmente.

Este estudio aborda las propuestas didácticas que las escuelas infantiles llevaron a cabo durante el contexto de la pandemia, tomando específicamente el juego y la forma en que los docentes los presentaban en las redes sociales. Con base en una metodología cualitativa (STRAUSS; CORBIN, 2002), se analizan intensamente las publicaciones realizadas entre mayo y octubre de 2021 en cuatro escuelas ubicadas en diferentes barrios del Área Metropolitana de Buenos Aires (AMBA). Los resultados muestran que las escuelas elaboran publicaciones con diferentes objetivos y contenidos. El número de puestos sobre actividades recreativas difiere según el “grado de formalización” de las instituciones (SIRVENT, 2008). Específicamente, las publicaciones sobre juegos, se caracterizan por presentar diferentes tipos de actividades lúdicas y formas de enseñanza y orientación a las familias por parte de los docentes. Los datos aportan evidencia sobre los aspectos a tener en cuenta para promover la inclusión genuina del juego (SARLÉ, 2017) y el lugar que ocupa la escuela para enriquecer la experiencia y potenciar la posibilidad de jugar.
IMPERIALISMO NA AMÉRICA LATINA. AS AÇÕES DO TIO SAM NOS ANDES BOLIVIANOS
Authors: Amorim de Sousa Adilson , Maciel de Jesus Elias
Published: June 2023

A América Latina, sempre foi palco de interesses das grandes potências, com destaque para a presença dos EUA, que utilizou de todos os mecanismos para garantir o controle sobre a região. A Bolívia, em função das suas riquezas naturais, constituiu-se em um território de amplas disputas, tendo se tornado uma área de controle do imperialismo estadunidense. No período recente, a ascensão dos movimentos populares e a vitória política do Movimento ao Socialismo (MAS), com Evo Morales, trouxe uma nova configuração política e econômica ao país, situação que tem contrariado, diretamente, os interesses do grande império do Norte e provocado momentos de tensões, e uma forte mobilização dos EUA, com o fim de retomar o controle do país. Portanto, é alvo central desse artigo, analisar o governo de Evo Morales e a reação dos Estados Unidos na busca pela desestabilização desse governo, visando o retorno da sua hegemonia na região.
A PARTICIPAÇÃO DAS CRIANÇAS SEM TERRINHA NA LUTA PELA TERRA E REFORMA AGRÁRIA NO BRASIL
Authors: Ramos Marcia Mara

RESUMO

Este artigo resulta das experiências educativas com as crianças Sem Terrinha do MST e tem como objetivo socializar o processo de construção da concepção de infância na luta pela terra no Brasil, vinculada ao Projeto de Reforma Agrária Popular. Esse processo se fortalece na luta da agricultura camponesa e familiar, em que as crianças também constroem o seu lugar de existência e de experiências. Na dureza e luta das crianças da classe trabalhadora, que teimosamente gritam para o rompimento das estruturas impostas pelo poder hegemônico, a infância Sem Terrinha se reinventa socialmente para continuar existindo enquanto criança e resistindo com seus familiares na construção coletiva do seu lugar enquanto sujeito da história. Nossas considerações sobre essa experiência evidenciam que o processo educativo da luta pela terra e o projeto de reforma agrária no MST permitem que as crianças do campo reinventem sua infância mesmo em tempos de pandemia, por meio da atenção, dos cuidados e da organização em contexto remoto, garantindo o lugar de participação política das crianças no MST.

O DESENVOLVIMENTO CONTRA A POTÊNCIA DA INFÂNCIA
Authors: Gama Noronha José Eduardo
Published: June 2023

O livro ‘’Direito ao Desenvolvimento’’ se soma ao crescente número de pesquisas dos Estudos da Infância no Brasil, a partir de um olhar crítico ao direito da infância e ao conceito de desenvolvimento. Fruto da tese de doutorado do autor, a obra se fundamenta na genealogia de Foucault para se voltar aos caminhos legais, históricos e forças em disputa em torno do conceito de desenvolvimento como chave para entendermos as subjetivações jurídico-políticas de crianças e adolescentes. Se destacando das demais obras que versam sobre a articulação entre infância e direito, pautadas principalmente pelo viés protetivo, o livro se propõe a fundamentar uma nova compreensão de sujeitos de direitos a partir de autores pós-estruturalistas e consolidar a importância da participação política de crianças e jovens como possível, necessária e legítima.
A EDUCAÇÃO INFANTIL EM TEMPOS DE PANDEMIA EM PERIÓDICOS CIENTÍFICOS PUBLICADOS (2021 A 2023)

O objetivo deste artigo é analisar quatro textos que foram publicados de janeiro de 2022 a abril de 2023 sobre a educação infantil e a pandemia de COVID-19. Esta pesquisa se configura como um estudo documental de natureza exploratória e de caráter qualitativo, tendo como fonte o site do Scientific Electronic Library Online (SciELO). Utilizamos os descritores “educação infantil” e “pandemia” e localizamos um total de nove trabalhos, dos quais três são sobre pesquisas no campo da saúde; um apresenta dados de estudo longitudinal com crianças de educação infantil realizado entre 2017 e 2018; um sobre crianças influenciadoras digitais e quatro abordam a educação infantil no contexto da pandemia. Os trabalhos analisados evidenciam diversos conflitos vivenciados pelos profissionais e pelas crianças da educação infantil nos dois primeiros anos de pandemia de COVID-19. Destacam-se a omissão do governo federal; as ausências de políticas públicas integradas; as mazelas da população; a presença de tecnologias digitais como principal instrumento de trabalho e o papel das famílias como mediadoras do processo de ensino-aprendizagem estabelecido entre escola e crianças.

The economies of West African Monetary Zone (WAMZ) countries have recorded a long trend of currency devaluation and hiking instability in oil prices. We estimated the covariance of currency devaluation and volatilities in global oil prices caused by the COVID-19 outbreak on WAMZ economies from January 30 to December 30, 2020. The BEKK model was estimated for analysis. The results from generalized autoregressive conditional heteroskedasticity (GARCH) show that all variance equation coefficients, are significant, suggesting strong volatility transmission and spillovers between the COVID-19 outbreak and oil price shocks on the economic performance of WAMZ. The estimates obtained for both current and lagged gross domestic product (GDP) equations are relatively similar. Consequently, all WAMZ economies weakly responded to shocks arising from fluctuations in international oil prices, volatility of inflation rate, and excess devaluation caused by the COVID-19 outbreak. The instabilities in oil prices and devaluation caused by the COVID-19 outbreak had decelerating consequences on the output growth of WAMZ economies. The estimated covariance effects of oil price shock and currency devaluation are negative for all countries in the study. A 1 percent devaluation-oil price shock caused by the COVID-19 pandemic resulted in negative output growth rates of 1.3 percent, 1.12 percent, 1.1 percent, and 1.09 percent in Nigeria, Sierra Leone, Ghana, and The Gambia, respectively.
Temperature Oscillations Along a Straight Fin
Authors: Sadik Shalom
Published: June 2023

This paper deals with a periodic heat transfer along straight fins. The
heat transfer is due to temperature fluctuations at the base of the fin.
The paper introduces a general physical model for any constraint
configuration using Fourier series when it is needed. Beyond the basic
example, the cosine constraint, the paper presents two examples:
absolute cosine constraint and square wave. All constraints show that
the oscillations ability to penetrate the fin decreases with increasing
frequency. It has been found that for a symmetrical time constraint such
as the base cosine constraint, increasing the frequency leads to a
convergence of the relative temperature to a zero value. For asymmetric
constraint such as the absolute cosine constraint and the square wave,
the convergence is to a positive value other than zero. Increasing the
Biot number leads to a convergence to zero value in all constraints
types.

Organic solar cells (OSCs) have already been a popular topic of research
for a long time. As a well-known electron transport layer (ETL) material
for the inverted device architecture, sol-gel-derived ZnO displays
certain defective surfaces that cause excessive charge recombination and
lower device performance. While UV-light soaking is a requirement for
the ZnO layer to function properly, the same can also be caused by the
photodegradation of conjugated organic semiconductors. The
photostability of OSCs has always been a hot research topic, as the
radiation of UV light may cause changes in the material’s properties,
and that, in turn, may cause rapid attenuation of the devices. Herein,
ZnO is modified by inserting the commonly used sunscreen ingredient
benzophenone-3 (BP-3) between the photoactive layer, consisting of a
PM6:Y6 blend, and ZnO to reduce the impact of UV radiation on the
photosensitive layer. The addition of BP-3 successfully enhances the
photovoltaic parameters, and a remarkable open-circuit voltage (Voc)
value of 0.887 V is obtained for PM6:Y6-based inverted solar cells,
corresponding to a Voc loss as small as 0.547 V. Finally, the
application of this strategy raises the device’s power conversion
efficiency from 12.44 to 13.71% and provides improved UV stability.
