PHOTOLUMINESCENCE PROPERTIES OF Nd3+, Yb3+ CODOPED Ga2O3 NANOPARTICLES
Authors: DULDA Ayşe
Published: March 2023

The availability of sensitive photon detectors and inexpensive lasers allowed us to explore more efficient fluorescent probes that will work in the second near-infrared optical window. In this study, the optical properties of Nd3+ and Yb3+ co-doped Ga2O3 nanoparticles were studied. In order to indicate the correlation between particle size, crystallinity, and optical property of present samples XRD, TEM, and Photoluminescence analyses were performed. Various excitation wavelengths and dopant concentrations were used to understand the energy transfer mechanism in Nd3+ and Yb3+ co-doped Ga2O3 nanoparticles. As the excitation wavelength increased from 325 nm to 477 and 515 nm, Yb3+ emission peak intensity decreased while Nd3+ emission peak intensity increased. This inverse relationship between the emission intensities of Yb3+ and Nd3+ ion showed the presence of energy transfer between them. The resulting emission peaks were broad and weak, indicating the presence of a non-radiative decay channel due to the crystal defects.

Authors: DEMİREL Murat
Published: March 2023

Sürdürülebilir kalkınma düşüncesi, özellikle son çeyrek yüzyılda daha çok ekonomik yaklaşımlar ile çevre sorunlarına çözümler aramaktadır. Çevre koruma ve çevre geliştirme politikalarına piyasacı yaklaşımlar eliyle, piyasa mekanizmasına ait ekonomik araçlarla yön verilmektedir. Ekonomik araçlar kısa vadede keskin çözüm üretmekte başarılıdırlar. Ancak çözüm üreten ekonomik araçların olumlu etkilerini uzun vadeli hale getirecek, kalıcılığını sağlayacak ve ekonomik yaklaşımın güçlüklerini alt edecek şekilde çevre koruma ve çevre geliştirme adına etik sınırlar çerçevesinde bireysel tutum ve davranış kalıpları benimsenmesi elzemdir. Çevre bilincine sahip bireysel bir bakış açısına ve çevre bilincinin bireysel boyuttan toplumsal boyuta taşınmasına ihtiyaç duyulmaktadır. Piyasacı çözümlere bir örnek olarak bu çalışmada 2019 yılı ile birlikte Türkiye’de hayata geçirilen plastik poşetlerin ücretlendirilmesi uygulaması incelenmektedir. Uygulamanın, plastik poşet kirliliğini azaltmak, sıfır atık projesine katkı sunmak gibi ana hedefleri dışında çevre bilinci üzerine yapacağı olası katkılar, Kafkas Üniversitesi öğrencilerine uygulanacak bir anket çalışması ile değerlendirilmektedir.

Authors: Yandra Alexsander , Faridhi Adrian , Andrizal Andrizal , Suyito Suyito
Published: March 2023

This study tries to examine the findings of the election supervisory body (Bawaslu) regarding 32,556 anomaly voters ahead of the 2019 general election in Riau. This trend occurs because of the unsynchronization of data from the Regional General Election Commission (KPUD), the Central Statistics Agency (BPS) and the Population and Civil Registration Office (Disdukcapil) of Riau Province. Findings in the form of poor accuracy in determining the voter list by the KPUD of Riau Province have caused dynamics and polemics in the community. By using the concepts of Election theory and Democracy and Community Political Rights with a single case qualitative approach, this study finds that the potential for people whose data is not recorded by the Disdukcapil will not only lose their right to vote in elections but can also lead to potential violations of Human Rights. Therefore, this study tries to provide an early warning about the potential negative consequences of inaccurate voter data.

Published: March 2023

Spinal muscular atrophy is an inherited neurodegenerative illness characterized by muscle wasting and loss of spinal cord motor neurons. It results from homozygous loss, translation, or mutation of the survival motor neuron 1 (SMN1) gene. Despite the lack of a cure, research has revealed potential processes explaining the disease’s molecular etiology. The SMN1 gene region’s distinctive genomic structure has been used to design treatment plans. Several stages of development have been recognized for a number of possible therapeutic agents. The standard of treatment for people having spinal muscular atrophy has evolved as a result of these and other healthcare technological advancements. In this review, we provide a comprehensive review of general introduction, types, symptoms, causes, diagnosis, and possible management of spinal muscular atrophy (SMA)..

Published: March 2023

The study was intended to explore the potential role of Moringa oleifera leaf extract (MOLE) on cisplatin (CIS) induced neuronal damage in experimental male rats. In the current work, animals were divided into four groups, six animals in each group. Group-1 (Normal) administered with Distilled water 1ml p.o. Group-2 (CIS) was received cisplatin 5mg/kg, ip. single dose. Group-3 (CIS + MOLE 200mg/kg) was orally administrated MOLE 200mg/kg, dissolved in water for 14 days with a cisplatin 5 mg/kg, ip. single dose on 10 day and Group-4 (CIS + MOLE 400mg/kg) was orally administrated MOLE 400mg/kg, dissolved in water for 14 days with a cisplatin 5mg/kg, ip. single dose on 10 day. After 14 days of MOLE dosing, the rats were sacrificed after anesthetizing with ketamine. Brain of individual rat was excised and processed for evaluation of oxidative injury markers like malonyl dialdehyde (MDA), glutathione (GSH), superoxide dismutase (SOD), catalase and histopathological study. MOLE treated experimental groups explored a potential (P<0.001) protection against CIS induced neurotoxicity by elevating the GSH, SOD, catalase and suppressing MDA in the brain as well as amelioration of histopathological changes induced by CIS at different doses. Thus, investigational finding revealed that MOLE possess potential benefits against neurotoxicity induced by anti-cancer drug cisplatin by regulating oxidative stress markers and ameliorating neuronal death and alteration of microanatomy of rat brain.

More Information, Lower Price? Access Market-based Reference Prices and Gains in Public Procurement Efficiency
Authors: Martinez-Carrasco José , Conceição Otavio , Dezolt Ana Lúcia
Published: March 2023

The paper examines the impact of providing market-based reference prices on public procurement efficiency in Brazil. Specifically, the study focuses on the State Secretariat of Health (SES) in Rio Grande do Sul and the algorithm developed by the local tax administration to calculate representative reference prices for pharmaceutical products. Unlike previous studies, reference prices are calculated based on the universe of local business-to-business transactions. The study finds that SES procurement officers access to this information caused a significant reduction in purchase unit prices, particularly for products characterized by a higher ex-ante unit price, a smaller number of suppliers, and purchased by a smaller number of public institutions. The gains in efficiency are attributed to the use of up-to-date market information, which is particularly useful for products where information asymmetry is more likely to exist between procurement officers and private providers.

Published: March 2023

Monthly cash transfers delivered to vulnerable middle-income households in Colombia increase per capita income, but the effects on spending appear small and related to nonfood spending. Cash transfers have a large impact when beneficiary households experience severe economic shocks, suggesting lack of insurance as a major constraint affecting non-poor but vulnerable households. By encouraging the adoption of digital saving accounts, the program also increased access to formal credit.
A Hybrid Model Combining Discrete Wavelet Transform and Nonlinear Autoregressive Neural Network for Stock Price Prediction: An Application in the Egyptian Exchange
Authors: Fathi Asmaa Y. , El-Khodary Ihab A. , Saafan Muhammad
Published: March 2023

Forecasting stock prices is crucial for successful investment in financial markets. However, it is challenging due to the nonlinearity and high volatility caused by various factors influencing price movements. This paper proposes a hybrid model that integrates the discrete wavelet transform (DWT) with the nonlinear autoregressive neural network (NARNN) to predict stock prices. Following the division of stock prices into training and testing sets, the DWT decomposes the training set into low- and high-frequency components reducing the noise and lessening the data's nonlinearity. Then, the obtained components are used to train the NARNNs. To predict the future components, the model decomposes the preceding available prices at each time step and utilizes the latest eight points as input to the NARNNs. Eventually, NARNNs' outputs are combined to provide the final predicted prices. In previous works, the entire dataset is first decomposed and then partitioned into training and testing sets. This unrealistic approach causes the testing set to inherit information regarding stocks' future performance, leading to optimistic deceptive results. Twenty-four stocks from the Egyptian Exchange (EGX-30) are utilized to validate the proposed model's performance. The DWT-NARNN model is compared against other methods, and the empirical findings show that it performs the best.

Published: March 2023

In the present era, the agricultural sector played a significant role in the development of the nation by creating jobs for rural people and developing of agricultural sector needed in labour-intensive nations like India. Hence, the study examined the relationship between public expenditure on agriculture and economic growth, public expenditure on agriculture and agricultural output in the context of India. Therefore, the study used the Unit root test, Cointegration test, Var, and ECM for analysis. The results show that there is no cointegration vector between public expenditure and economic growth and found that negative relationship between public expenditure and economic growth. But, the study reveals that there is a cointegration vector between public expenditure and agricultural output. Significant Error Correction term (ECt-1) indicates that 85.2 per cent of total disequilibrium in public expenditure on agriculture and agriculture output is corrected each year in India. The coefficient of the EC2t-1 term is statistically insignificant. shortrun coefficients are also insignificant, which concludes that there is no short-run causality between public Expenditure and agriculture output in any direction. One way causality exists from agriculture output to public expenditure in the long run and is supported the Wagner’s hypotheses instead of Keynesian Hypotheses in India.

Wszystko na swoim miejscu – rola receptorów VPS10P w komórkowej segregacji białek
Authors: Kamińska Paulina , Piątek Sylwia , Bieniek Magdalena , Malik Anna
Published: March 2023

Receptory z domeną VPS10P (ang. vacuolar protein sorting 10 protein) stanowią rodzinę białek sortujących, które kierują wewnątrzkomórkowym transportem swoich białkowych ligandów, odpowiadając tym samym za ich prawidłowe lokalizowanie w obrębie kompartmentów komórkowych. Rola receptorów została scharakteryzowana głównie w neuronach, gdzie efektywny system sortowania białek stanowi kluczowy element ich prawidłowego działania, a jego dysfunkcje mogą prowadzić do upośledzenia procesów związanych z plastycznością synaptyczną czy rozwoju chorób neurodegeneracyjnych. Receptory z domeną VPS10P pełnią także ważną rolę w regulacji procesów związanych z metabolizmem tłuszczów, transportując enzymy biorące udział w ich biochemicznych przemianach czy uczestnicząc w pobieraniu przez  komórki  lipoprotein. Ostatnie doniesienia wskazują, że receptory z domeną VPS10P stanowią również istotny element związany z odpowiedzią immunologiczną, w którą zaangażowane są zarówno komórki układu odpornościowego, jak i glejowe. Nie bez znaczenia pozostaje także ich rola w patogenezie chorób nowotworowych.

Reconfiguración del mandato de masculinidad en la figura parental en textos autoficcionales de Marcos Giralt Torrente, Guadalupe Nettel y Jeanette Winterson
Authors: Villegas Salas Lilia Irlanda
Published: March 2023

Mediante el análisis de las relaciones de parentalidad en Tiempo de vida, El cuerpo en que nací y ¿Por qué ser feliz cuando puedes ser normal?, de Marcos Giralt Torrente, Guadalupe Nettel y Jeanette Winterson respectivamente, se expondrá cómo la literatura autoficcional, en tanto ejercicio artístico, adquiere también una función capaz de reconfigurar la realidad patriarcal y, así, contribuir a desmontar un esencialismo estructural. La incipiente actualidad de estos autores constituye también una propuesta de escrituras descentralizadas o marginales leídas desde el Sur: literatura de los hijos parentales, literatura de mujeres y literatura con perspectiva homoerótica. Para ello, partiendo de una metodología comparatista literaria desde epistemologías de género del Sur, se ejemplifican y visibilizan costumbres heteronormativas de un contexto capitalista que deteriora la identidad de un yo relacional, en un sistema político, social y económico jerárquico y represor. Se realiza un análisis de personajes que rompen con la idea estereotípica de relaciones familiares, permitiendo así esbozar nuevas concepciones de identidad a partir de una serie de autores clave en el tema de la ruptura heteronormativa. La presente es una apuesta en favor de la literatura como un arte que, además de brindar goce estético, puede constituir una poderosa vía de concientización y transformación epistémica –es decir, del desplazamiento del deseo–, a partir de la experiencia humana, en general y, en particular, a través de la experiencialidad ficcional (cargada de tintes autobiográficos) de un yo-relacional que da cuenta de vicisitudes relacionadas con el mandato de masculinidad, entendido como “la obligación de dominio que recae sobre los hombres” de algunos personajes literarios. Tal obligación [y la] “investidura [social que se impone] a quienes cargan un cuerpo masculino” son cuestionadas e incluso transformadas en los textos seleccionados que, cuando son explorados en el marco de la educación superior, pueden contribuir a la educación inclusiva en el Sur global.

Published: March 2023

O café é a segunda bebida quente mais consumida no planeta. O Brasil é reconhecido como o principal protagonista na produção e exportação de café; sendo assim a busca pelo aumento de produção sem expansão da área física plantada é um caminho da sustentabilidade e pilar das pesquisas agrícolas em regiões tropicais. Diante disso, o presente estudo tem como objetivo apresentar uma técnica inovadora, sustentável e ecologicamente correta para a proteção de plantas cultivadas a pleno sol, a fim de assegurar o contínuo crescimento da produção do café no Brasil. Trata-se da pulverização do mineral caulim sobre plantas comercialmente cultivadas de café; um mineral inorgânico, natural, processado, purificado e formulado, disponível sob a marca comercial Surround®WP. Considerou-se como metodologia aplicada, a pesquisa descritiva e explicativa, com vistas à identificação da relação entre a temperatura do ar, temperatura sobre as plantas e seus danos causados às plantas através do procedimento técnico da pesquisa bibliográfica. De forma geral, a elevação da temperatura do ar causa estresse térmico no cafeeiro e favorece a queimadura das folhas, causada pelo excesso de radiação solar, deixando a planta vulnerável a insetos não desejáveis. Os resultados dos estudos revisados demonstraram que a aplicação do caulim contribuiu significativamente para o aumento da produtividade, melhoria na qualidade dos grãos e agregação de valor ao produto comercializado. Desta forma, o produto poderá ser importante aliado para o contínuo crescimento sustentável e economicamente viável da cafeicultura brasileira.

Published: March 2023

O presente estudo toma como proposta de reflexão a realidade da Educação Básica brasileira que revela, segundo estatísticas do Programa Internacional de Avaliação de Alunos (PISA) - 2018, problemas consideráveis em relação à competência leitora dos estudantes. Considerando a perspectiva teórica Semântico-Enunciativa de Guimarães (2002, 2018), propõe o Método Enunciativo de Leitura (MEL) enquanto pedagogia multidisciplinar de desenvolvimento de competências que viabilizem, concretamente, habilidades leitoras em quaisquer áreas do conhecimento. Este dispositivo reporta-se à prática de leitura de textos que circulam nas esferas sociais desses alunos - cuja temática seja a abordagem à Cultura e História Regional/Local dos municípios - e a procedimentos de análise sob uma perspectiva enunciativa.

Radio espacio estacion broadcast Fordlândia
Authors: Toledo Gabriela Paiva de
Published: March 2023

On September 16th and 17th, 2017, the nomadic online radio station radioee broadcast from Fordlândia, today a district of the city of Aveiro, state of Pará, in the Brazilian Amazonia. Produced by artist Augustina Woodgate along with cultural producers Stephanie Sherman and Hernan Woodgate and several other partners in every new location, Radio Espacio Estacion/radioee was conceived as a multilingual, mobile, online radio station set up around 24-hour/36-hour long events broadcast from different parts of the world to discuss issues of migration, mobility, transportation, environment, and climate change. In Transmissão Fordlândia, radioee revisited the legendary history of the site’s foundation by the Ford Motor Company in 1927. The broadcast questions the official narrative of desertion after Ford’s enterprise failed, which implies ideas of underdevelopment associated with a colonial modern economy of representation of Latin America. Adopting live and online radio communication, based on immediacy, synchronicity, and accessibility, Transmissão Fordlândia combined research, interviews, and first-hand descriptions of the site in a continual multilingual conversation, producing a non-linear narrative enriched with a bustling soundscape of people, birds, water, motorcycles, boats, and everyday activities, transmitted to a global audience. This paper investigates how Transmissão Fordlândia articulates an ecocritical approach to space through site-oriented practices and sonic-spatial imagination, challenging colonial modern representations of tropical landscapes based on spatial rationalization and the duality of culture–nature. This paper also explores the sonic-spatial effects of live radio transmission as an aesthetic device for imagining place.
Principio Potosí
Authors: Proença Luiza
Published: March 2023

A produção e circulação de imagens foram cúmplices na imposição do capitalismo de modo a dificultar que a crise ecológica global atual seja visualizada. Este artigo investiga formas de contravisualidade e resistência no campo transcultural da arte. Está focado na exposição Principio Potosí: ¿Cómo podemos cantar el canto del Señor en tierra ajena? [Princípio Potosí: como podemos cantar a canção do Senhor em terra estranha?], realizada entre 2010-2011 em diferentes instituições de três países da Europa e América do Sul. Conduzido pela figura do diabo e suas diversas expressões, o texto aborda a exposição em termos da multiplicidade de perspectivas apresentadas e do exercício herético necessário para dissolver a violência potencial implícita nas manifestações e instituições artísticas. Nesses termos, a contravisualidade se desdobra em práticas de contrafeitiçaria anticapitalista.
Exposições do antropoceno no sul global
Authors: Melo Natália Nascimento e
Published: March 2023

Que significados tem para a arte o encontro com o Antropoceno? Partimos de um conjunto de 66 exposições para refletir sobre o papel dos museus e da arte na construção da literacia científica e compreensão dos lugares ocupados pelo humano no planeta. Apesar de uma maior expressão no número de exposições ser encontrada na Europa e América do Norte, encontramos a Sul exemplos que se destacam e permitem que nos debrucemos sobre as diferentes relações que surgem da triangulação entre as artes, as ciências e as expressões políticas. É nesse cenário geográfico que encontramos novos conceitos, continuidades e permanências, permitindo colocar países como Brasil, Colômbia e Taiwan na vanguarda de uma tendência expositiva do Antropoceno que vai além da ciência e do ativismo.
Reativar o vivo, atravessar a floresta
Authors: Huven Paula
Published: March 2023

A partir de variadas expressões poéticas – fotográfica, cinematográfica, pictórica e literária – proponho contornar a ideia de vivo. Minha série fotográfica Água viva desenha a aproximação de uma menina com as águas correntes da cachoeira. A criança entra em contato com a matéria do mundo e com o invisível da natureza, sem margens que os distingam. Naomi Kawase, em seu filme Floresta dos Lamentos, mostra-nos que atravessar a floresta é, necessariamente, ser atravessada por ela. A artista Wilma Martins constrói pictoricamente irrupções da floresta no cenário domiciliar e, assim, ela dá forma ao vínculo entre o real e o imaginário; entre o selvagem e o domesticado. A personagem G.H., de Clarice Lispector, vive uma epifania a partir do encontro com uma barata – ser arcaico, remoto, imemorial, travessia íntima e subjetiva que faz emergir o mais primitivo de si. Entre o mundo que olhamos e o que vemos, o visível e o invisível, a matéria e o espírito, humano e não humano, somos atravessados pela energia do vivo. Reativar, palavra-chave no vocabulário da filósofa belga Isabelle Stengers, leva-nos de volta em direção ao vínculo com os deuses, os espíritos, a terra e, com estas alianças, reativar o vivo se compõe.
Ensaio manifesto - estética de existência
Authors: Goulart Marilu , Farias João Maurício
Published: March 2023

A presença dos povos indígenas na região metropolitana de Porto Alegre e suas lutas para manterem as práticas ancestrais de seus modos de existência, têm contribuído para que o “céu de Porto Alegre” não caia. Estes povos têm experimentado grandes tensionamentos decorrentes das disputas de seus territórios em razão da especulação imobiliária e da extração mineral de carvão, que os colocam no centro dos acontecimentos. Tais situações tendem a agravar ainda mais a degradação ambiental e a qualidade de vida na região. O narrador e a narração, como Walter Benjamim apontou, poderiam, em determinados momentos históricos, abrir as brechas para que a perspectiva dos vencidos de outrora possam emergir e recontar as suas histórias. Neste sentido, o encontro de dois pesquisadores com os povos indígenas Mbya-Guarani e a produção literária de indígenas como Davi Kopenawa e Ailton Krenak compõem a criação desta narrativa.
Experiência informe
Authors: Araujo Mariany Silva Gomes de
Published: March 2023

A partir da experiência do choque formulada por Walter Benjamin enquanto estrutura síntese da sensibilidade europeia moderna, inscrita nas transformações contextuais do período e em seus modos de representação, procura-se examinar como este contato específico com a realidade vincula-se, mais tarde, a afetos observados na segunda metade do século XX pela experiência aporética e ambígua aqui identificada como “informe”. Para isso percorre-se, além do choque benjaminiano, o pensamento sobre o realismo traumático de Hal Foster, bem como as noções de informe bataileana e dessubjetivação foucaultiana como modos de perturbação de uma subjetividade organizada, à época, principalmente pela fenomenologia. Pensar o possível elo entre obras produzidas no final do século XIX, por um lado, e em meados da década de 1960, por outro, visa, além de contribuir com sua investigação morfogenética, articular seu reposicionamento em relação à exaltação ou supressão da experiência que promovem.
Repensando as conexões entre arte e ecologia a partir do sul global
Authors: Maroja Camila , Siqueira Vera Beatriz
Published: March 2023

Este dossiê trata das relações entre arte e ecologia a partir das perspectivas latino-americana e do Sul Global. Os artigos aqui reunidos buscam precisamente repensar essas relações e analisar a produção artística gerada desde o impacto da emergente conscientização ambiental na arte e no modo como a arte é pensada. Demonstram a importância não só de apresentar noções ecológicas provindas da América Latina e de outros espaços pós-coloniais na criação artística contemporânea, mas também de repensar a historiografia e a análise da arte a partir de novos parâmetros que reconsideram o papel da natureza na arte.

Objetivo: Avaliar a situação de Insegurança Alimentar entre famílias de escolares de uma escola da rede municipal de ensino do meio rural de um município da mesorregião Centro-Sul do Paraná e seus fatores associados. Métodos: Trata-se de um estudo transversal descritivo, constituído por um questionário semiestruturado autoaplicável, contendo questões sociodemográficas e da Escala Brasileira de Insegurança Alimentar, com os familiares dos escolares de primeiro a quinto ano. Resultados:  Foram avaliadas 53 famílias, das quais 49% se encontravam em insegurança alimentar (IA), sendo 26,4% em IA leve e 22,6% em IA moderada. A prevalência de IA foi maior em famílias cujo chefes de família eram mulheres (73,1%), com idade acima de 30 anos (61,5%), que possuíam até o ensino médio completo/incompleto (57,7%), que se autodeclararam brancas (76,9%) em domicílios de 4 ou mais pessoas (53,8%), com renda familiar de mais de um salário mínimo (57,7%) e que eram beneficiários de algum programa de transferência de renda (61,8%). Conclusão: Diante do aumento dos índices de IA nos últimos anos e a piora com a Pandemia da Covid-19, ressalta-se a importância da implantação de políticas e programas que visem acompanhar e combater a IA das famílias, sobretudo na área rural.
