Symbiotic Endophytes of Glomalin AM Fungi, Rhizobium, and PGPR Potential Bio stimulants to Intensive Global Food Production for Sustainable Agriculture System
Authors:   Centre for Advance Agriculture Research, Absolute Bioscience, Plot No. 68, Sector-44, Delhi NCR, Gurugram-122003, Haryana, India
Published: July 2023

Endophytic microorganisms are symbionts that live inside plant tissues and have been studied for their potential growth-promoting effects on plants and their beneficial involvement in plants’ responses to various stresses. Endophytic microorganisms play an important role in plant health, and this research looks at the processes they stimulate to increase plant tolerance to a variety of stresses. The endophytic microbial population boosts plant development by creating secondary active chemicals that defend the plant against pests and diseases. Endophytes also generate extracellular enzymes that are essential to the colonization of endophytes inside the plant host. Microbial endophytes may act as growth-promoting agents for plants by producing phytohormones and assisting plant development in polluted soils by degrading toxic chemicals. Endophytes regulate plant development via many mechanisms in response to stresses such as salt, drought, temperature, heavy metal stress, and nutritional stress. The glycoprotein glomalin-related soil protein (GRSP) is produced by the arbuscular mycorrhizal fungus (AM fungi) and is crucial to ecosystem health, the production of high-quality food, and ecological restoration. Soil globulin levels are highly associated with aggregate water stability (WS) and soil quality (SH). Since globulin contains carbon, it makes a non-negligible contribution to the Earth’s terrestrial carbon reservoir. The GESP-producing AM fungus are ubiquitous root symbionts that benefit plants in a wide variety of ways. Root nodules of legumes are home to soil bacteria (SB) called rhizobia, which fix nitrogen (LRN). Plant growth-promoting rhizobacteria (PGPR) are a class of free-living bacteria (FLB) that colonize the rhizosphere and improve root development (RG), which in turn improves plant growth (PG), productivity, and numerous plant growth-promoting substances (PGPS). During symbiosis, symbiotic fungi (SF) and bacteria reproduce using host resources to replenish the soil, endure between hosts in the soil, and discover and infect new hosts. The present publication emphasizes the significance of microbial symbionts and their interactions for nutrient management, effective for growth and productivity to the sustainable agricultural system (SAS), which boosts worldwide crop output.

Published: July 2023

This research aims to explore the effectiveness of inclusive learning approaches in improving students' literacy skills in Elementary Schools (SD). Literacy is a key component in education that plays a crucial role in shaping the foundation of lifelong learning for students. However, various factors such as different ability levels, diverse learning styles, and variations in social and cultural backgrounds often hinder students from achieving optimal literacy levels. In this study, an inclusive learning approach was adopted to create a learning environment that accommodates the needs and individual differences of each student. The research method used was Classroom Action Research (PTK) involving several classes in an elementary school. Data were collected through pre-and post-literacy tests, classroom observations, and interviews with teachers and students. The results of the study show that the inclusive learning approach has a significant positive impact on improving students' literacy skills. When students are empowered to learn in an inclusive environment, they tend to show better improvements in reading, writing, and text comprehension. Additionally, students also demonstrate increased active participation and motivation in learning, as they feel valued and supported throughout the learning process. The findings of this research underscore the importance of creating inclusive and supportive learning environments for students in SD. Teachers and educational institutions should strive to identify individual student needs, provide appropriate support, and employ diverse teaching methods to facilitate improved literacy skills. Thus, inclusive learning approaches can be an effective means to enhance the quality of education and create a brighter future for SD students in facing the challenges of a knowledge-based society.

Authors: Gümüş Meltem , Baltaci Saltuk Bugra
Published: July 2023

Objective: This study was carried out to investigate whether dietary zinc status is associated with serum albumin, AST and ALT levels in male offspring of mother rats fed a zinc deficient diet.
Methods: The study was carried out on male offspring (Groups 1, 2, 3) born to rats fed a zinc deficient diet and on male offspring (Group 4) born to mothers fed a standard diet. Group 1: Zinc deficient, Group 2; standard rat chow, Group 3: Zinc supplemented diet. Animals of group 4 were used as control group. After the completion of the experimental stages of the study, albumin, AST, ALT, free and total bilirubin levels in serum samples taken from animals were determined by spectrophotometric method.
Results: Dietary zinc deficiency (group 1) significantly decreased serum albumin values (p<0.004). Animals in both the zinc deficient (Group 1) group and the Group 2 animals born to mothers fed a zinc deficient diet and fed standard rat chow had the highest AST and ALT levels (p<0.001).
Conclusion: The present study is the first to show that dietary zinc status can directly affect liver function in rats born to zinc deficient mothers by causing changes in serum albumin, AST and ALT levels.

Published: July 2023

Translation can be described as the activity of translating the meaning of text from one language to another or SL (source language) to TL (target language).This study focuses on the investigation of translation strategy used for Taylor Swift's song "Anti-Hero" A descriptive qualitative approach is used in this study. The process of choosing, concentrating, streamlining, abstracting, and changing the information found in the study's field notes and transcripts is sometimes referred to as the data gathering procedure. In parallel with the data collection method, data analysis was done. Out of the 18 methods based on Molina and Albir (2002), researchers can conclude that eight types of strategies are obtained from 47 data found in the translation of the lyrics to Taylor Swift's song "Anti-Hero."The strategies found include; Amplification (15 data) 32%, Borrowing (5 data) 11%, Calque (1 data) 2%, Discursive creation (1 data) 2%, Establish equivalence (11 data) 23%, literal translation (10 data) 21% and reduction (4 data) 9%. It was found that the type of amplification translation strategy was the strategy that appeared the most with a percentage of 32% of all translation techniques found so that it became the most dominant type of translation used by translators in lyrics of the song 'Anti-Hero'. While the strategies of calque and discursive creation were the fewest translation strategies with a percentage of 2% in the translation of the lyrics of the song 'Anti-Hero' from all the strategies found.

Decay rates for two Cauchy thermoelastic laminated Timoshenko problems of type III with interfacial sli
Authors: Guesmia Aissa
Published: July 2023

In this article we study the decay of solutions for two systems of laminated Timoshenko beams with interfacial slip, in the whole space \(\mathbb{R}\) subject to a thermal effect of type III acting only on one component.When the thermal effect acts via the second or third component of the laminatedTimoshenko beam (rotation angle displacement or dynamic of the slip),we prove that both systems are polynomially stable. Also we obtain stability estimates in the \(L^2 (\mathbb{R})\)-norm of solutions and their higher order derivatives with respect of the space variable. The decay rates, and the absence or presence of the regularity-loss type property, depend on the regularity of the initial data and the speeds of wave propagations. However, when the thermal effect acts via the first component (transversal displacement), we introduce a new stability number \(\chi\) and prove that the stability of the system is equivalent to \(\chi\ne 0\). An application to a case of lower order coupling terms is also given. To prove our results, we use the energy method in the Fourier space combined with well chosen weight functions to build appropriate Lyapunov functionals.

Authors: Zhang Bo , Liu Xiangqing
Published: July 2023

In this article, we study the existence of localized nodal solutions for semiclassical quasilinear Choquard equations with subcritical growth $$-\varepsilon^p \Delta_{p} v +V(x)|v|^{p-2}v = \varepsilon^{\alpha-N} |v|^{q-2}v \int_{\mathbb{R}^N} \frac{|v(y)|^q}{|x-y|^{\alpha}}\,dy ,\quad x \in \mathbb{R}^N\,, $$ where \(N\geq 3\), \(1<p<N\), \(0<\alpha <\min\{2p,N-1\}\), \(p<q<p_\alpha^*\), \(p_\alpha^*= \frac{p(2N-\alpha)}{2(N-p)}\), \(V\) is a bounded function. By the perturbation method and the method of invariant sets of descending flow, for small \(\varepsilon\) we establish the existence of a sequence of localized nodal solutions concentrating near a given local minimum point of the potential function \(V\).
Mathematical models for the transmission of malaria with seasonality and ivermectin
Authors: Zhao Zhihong , Shaochun Shaochun , Lu Yulan
Published: July 2023

Ivermectin has shown good effects for malaria control in clinical trial stages because it can kill mosquitoes feeding on recently treated individuals. In this article, we formulate and analyze a novel delay malaria transmission model taking into account seasonality and ivermectin. We show that the dynamics of the model is totally determined by the basic reproduction ratio \(R_0\) that is, malaria will gradually die out if \(R_0<1\) and will persist if \(R_0\geq 1\). Numerically, we verify the obtained theoretical results and evaluate the effect of ivermectin by related data of Kenya. We find that our simulation of the impact agrees with the prediction of the existing clinical trials in which it takes at least 25 years to eliminate malaria from Kenya with malaria control measures intact.
Ground state solutions for fractional p-Kirchhoff equation

Regular traveling waves for a reaction-diffusion equation with two nonlocal delays
Authors: Zhao Haiqin , Wu Shi-Liang
Published: July 2023

This article concerns regular traveling waves of a reaction-diffusionequation with two nonlocal delays arising from the study of a singlespecies with immature and mature stages and different ages at reproduction. Establishing a necessary condition on the regular traveling waves, we prove the uniqueness of noncritical regular traveling waves,regardless of being monotone or not. Under a quasi-monotone assumption and among other things, we further show that all noncritical monotone traveling waves are exponentially stable, by establishing two comparison theorems and constructing an auxiliary lower equation.

Published: July 2023

In this article we consider the fourth-order operators \(A_1u:=(au'')''\) and \(A_2u:=au''''\) in divergence and non divergence form, where \(a:[0,1]\to\mathbb{R}_+\) degenerates in an interior point of the interval. Using the semigroup technique, under suitable assumptions on \(a\), we study the generation property of these operators associated to generalized Wentzell boundary conditions. We prove the well posedness of the corresponding parabolic problems.

A semilinear wave equation with non-monotone nonlinearity and forcing flat on characteristics
Authors: Caicedo Jose F. , Castro Alfonso , Duque Rodrigo
Published: July 2023

We provide sufficient conditions on the forcing term for a semilinear wave equation with non-monotone asymptotically linear nonlinearity to have a weak solution. Earlier results required the forcing term not to be flat on characteristics, now we remove those requirements. Also we provide estimates on the measure of the level sets of the forcing term, that suffice for the equation to have a weak solution.

Global Climate Litigation Report: 2023 Status Review
Authors:   United Nations Environment Programme
Published: July 2023

This report, which updates previous United Nations Environment Programme reports published in 2017 and 2020, provides an overview of the current state of climate change litigation and an update of global climate change litigation trends. It provides judges, lawyers, advocates, policymakers, researchers, environmental defenders, climate activists, human rights activists (including women’s rights activists), NGOs, businesses and the international community at large with an essential resource to understand the current state of global climate litigation, including descriptions of the key issues that courts have faced in the course of climate change cases. This report further demonstrates the importance of an environmental rule of law in combating the triple planetary crises of climate change, biodiversity loss and pollution. Access to justice enables the protection of environmental law and human rights and promotes accountability in public institutions. The report was launched in conjunction with the anniversary of the United Nations General Assembly’s recognition of the human right to a clean, healthy and sustainable environment (A/RES/76/300), as the majority of cases brought before the courts demonstrate concrete links between human rights and climate change. The UNGA resolution, which recognises that climate change impacts have negative implications on the enjoyment of all human rights, is likely to drive further action on climate change in the future.
Violência de Estado, aprisionamento e subjetivação

Published: July 2023

O presente trabalho analisa enunciados escritos em paredes do presídio de Ahú, que era localizado em Curitiba. A reflexão toma como base a Análise Materialista de Discurso, a partir da qual os conceitos de formação discursiva, interdiscurso e contradição se tornam fundamentais para compreender o processo de significação, calcado em formas de existência material inscritas em paredes de penitenciária. Refletimos sobre a diferença entre pichação e grafite, compreendendo essas inscrições como formas de escritas de si. A análise trabalha sobre o excesso de negações nos enunciados do corpus e seu funcionamento discursivo. Concluímos que os enunciados são heterogêneos, tanto em relação à formação discursiva de identificação dos sujeitos quanto em relação com posições discursivas antagônicas. As paredes se tornam um lugar possível de se pronunciar contra as diferentes relações de opressão às quais o sistema carcerário brasileiro submete os apenados, garantindo-lhes somente o direito ao silêncio.
A imagem-narrativa da experiência por mulheres
Authors: Pavão Maria Rita Barbosa Piancó , Carvalho Mário de Faria
Published: July 2023

Neste trabalho, objetivamos refletir como os elementos simbólicos presentes nos bordados produzidos por arpilleristas chilenas durante a ditadura militar vivenciada pelo Chile (1973-1990) permitem pensar as experiências dessas mulheres. Para tanto, nos valemos de elementos teóricos próprios da Teoria do Imaginário de Gilbert Durand (2012; 2014), bem como das perspectivas traçadas por autores como Benjamin (1972; 1987; 2019), Larrosa (2002) e Scott (1999) acerca da experiência. Esta pesquisa foi estruturada a partir do método fenomenológico e classifica-se como sendo bibliográfica-exploratória, cujos resultados foram tratados qualitativamente e resultaram de uma análise atenta às dimensões da estrutura heroica, da estrutura mística e da estrutura sintética, melhor discutidos na teoria durandiana. Os resultados obtidos apontam para elementos simbólicos que desvelam memórias individuais e coletivas relacionadas à repressão, ao engajamento político, aos aspectos do cotidiano, às expressões de gênero, ao acolhimento e solidariedade dos agrupamentos e aos mortos ou desaparecidos pela ditadura militar.
CARTAS, DEFICIÊNCIA E FORMAÇÃO INICIAL DE PROFESSORES PARA CONTEXTOS INCLUSIVOS
Authors: Santos Balbino Elizete
Published: July 2023

O presente artigo é um recorte de um trabalho de Doutorado e tematiza a formação inicial de professores, com foco na invisibilidade das pessoas com deficiência. Trata-se de uma pesquisa qualitativa, que tem como corpus documental cartas escritas por licenciandos do curso de Pedagogia de uma universidade pública do Nordeste do Brasil. As cartas foram construídas na disciplina de Eduação Inclusiva. A escrita, a organização dos documentos e as sucessivas leituras foram realizadas sob inspiração da análise de conteúdo de Bardin. O argumento, por sua vez, foi construído sob a forma de ensaio. A análise das cartas demonstra a importância de inserir no campo da formação inicial de professores os estudos sobre deficiência, pois há, ainda, uma invisibilidade das pessoas com deficiência nas instituições de ensino, reforçando os discursos normocêntricos e as ideias capacitistas.
REFLEXÕES SOBRE O RACISMO E ANTIRRACISMO NO ENSINO SUPERIOR SOB A PERSPECTIVA DECOLONIAL
Authors: Pereira De Castro Betel , Foster Eugénia da Luz Silva , Custódio Elivaldo Serrão
Published: July 2023

As relações raciais no Brasil foram construídas sob a luz de teorias e ideologias que colocaram o negro como sujeito inferior. Nesse sentido, o racismo e seus derivados ainda permeiam o seio da sociedade brasileira de forma que a população negra não consegue ascender socialmente, mesmo após a abolição da escravatura. Este estudo visa analisar as relações raciais no que tange ao racismo e antirracismo na educação superior sob a perspectiva decolonial. A pesquisa se configura em um enfoque qualitativo, e a metodologia utilizada materializa-se na pesquisa bibliográfica e documental. Constatou-se que o racismo ainda é uma realidade presente nas relações que se dão no cenário brasileiro. Contudo, vislumbra-se uma educação antirracista mais ampla e efetiva não somente no tocante aos espaços acadêmicos, bem como outros segmentos da sociedade.

Background/Aims: Self-expandable metallic stents (SEMSs) are widely adopted for the palliation of dysphagia in patients with malignant esophageal strictures. An important adverse event is the development of SEMS-induced esophagorespiratory fistulas (SEMS-ERFs). This study aimed to assess the risk factors related to the development of SEMS-ERF after SEMS placement in patients with esophageal cancer.Methods: This retrospective study was performed at the Instituto do Cancer do Estado de São Paulo. All patients with malignant esophageal strictures who underwent esophageal SEMS placement between 2009 and 2019 were included in the study.Results: Of the 335 patients, 37 (11.0%) developed SEMS-ERF, with a median time of 129 days after SEMS placement. Stent flare of 28 mm (hazard ratio [HR], 2.05; 95% confidence interval [CI], 1.15–5.51; p=0.02) and post-stent chemotherapy (HR, 2.0; 95% CI, 1.01–4.00; p=0.05) were associated with an increased risk of developing SEMS-ERF, while lower-third tumors were a protective factor (HR, 0.5; 95% CI, 0.26–0.85; p=0.01). No difference was observed in overall survival.Conclusions: The incidence of SEMS-ERFs was 11%, with a median time of 129 days after SEMS placement. Post-stent chemotherapy and a 28 mm stent flare were associated with a higher risk of SEMS-ERF.
Oito anos de análise dos dados do experimento célula solar do segundo satélite brasileiro
Authors: Veissid Nelson , Beloto Antonio Fernando , Baruel Mario Ferreira
Published: July 2023

O segundo satélite Brasileiro (SCD2) foi colocado em órbita em Outubro de 1998 e carrega a bordo um experimento de células solares de silício (ECS). O objetivo principal do ECS é o de qualificar em missão e confirmar a confiabilidade das células solares que foram projetadas e fabricadas no Brasil. O ECS é um pequeno módulo composto de um arranjo de três pares de células solares acondicionadas numa estrutura mecânica de alumínio. Os três sinais gerados pelos pares de células são amplificados por um circuito elétrico localizado dentro da estrutura mecânica e são repassados para a telemetria do satélite, que transmite em digital seu valor para a estação receptora em Cuiabá-MS. Cada par de células simula o funcionamento da célula solar em três diferentes situações: tensão de circuito aberto, corrente de curto circuito e tensão de máxima potência. Um termistor colocado sob a estrutura mecânica monitora a temperatura do ECS. Os quatro canais (três de sinal e um de temperatura) são recebidos em tempo real e eles permitem recuperar as curvas de corrente por tensão nas condições padrões de temperatura e intensidade solar (25  C e AM0). Desta forma, pode-se calcular a degradação dos parâmetros elétricos da célula solar durante a vida do satélite. Este trabalho apresenta a análise dos dados recebidos pela telemetria durante os oito primeiros anos de vida do satélite SCD2. Neste período, podemos dizer que os danos de radiação sofridos pelas células solares provocaram uma diminuição relativa de 2,6% na eficiência, de 1,0% na corrente de curto circuito e de 1,7% na tensão de circuito aberto, em relação aos seus valores de inicio de vida. Estes valores de degradação são menores do que os esperados, conforme dados apresentados na literatura. Por exemplo, para o período de oito anos e condições de órbita do satélite, era esperado uma degradação relativa de 7% na eficiência de conversão e os dados do experimento revelaram umadegradação menor do que a metade do valor esperado.

Published: July 2023

O presente trabalho faz parte de estudos que estão sendo realizados no projeto de P&D Estratégico ANEEL chamada n.o 013/2011, comandado pela CEEE-GT e intitulado Inserção da Geração Solar Fotovoltaica Urbana Conectada à Rede em Porto Alegre. A utilização de energia solar fotovoltaica é amplamente difundida no mundo e possui caráter promissor no Brasil atualmente. Apesar do grande potencial brasileiro, esta fonte de energia ainda apresenta baixos níveis de utilização. A competitividade da geração fotovoltaica de grande porte em usinas solares fotovoltaicas ainda não atingiu patamares admissíveis com taxas de retorno financeiro atrativas ao mercado nacional. Por se tratar de uma fonte de energia renovável, sua utilização no cenário mundial tem apresentado crescimento nos últimos anos. Mesmo em países que apresentam potenciais solares inferiores aos do Brasil, esta fonte de energia tem se mostrado competitiva devido aos incentivos oferecidos. Tendo em vista este prisma, o presente trabalho busca apresentar possibilidades de inserção de usinas solares fotovoltaicas no Estado do Rio Grande do Sul. A usina proposta possui capacidade de geração de 30 MWp.

Neste artigo, foi realizado um estudo das características do recurso solar para cidade de Petrolina (PE) através da análise da quantidade de dias de céu claro, sendo relevante para projetos de instalação de usinas de energia solar térmica ou fotovoltaica. Os dados solarimétricos utilizados foram provenientes da estação SONDA. Determinou-se um modelo empírico de céu claro para região de modo a ajustar as curvas de irradiância global medida e estimada. Com os valores de irradiância global estimada, foi calculado, para todos os dias da base de dados, o valor de uma constante Kc que é dado pela razão entre as irradiâncias globais medida e estimada de céu claro. Foi definido que dias com o Kc maior que 0,94 podem ser considerados como dias de céu claro. Posteriormente, calculou-se as distribuições mensal e anual dos valores de Kc baseado na frequência dos valores desta constante. Procedimento semelhante também foi feito para Recife (PE). Dispondo dos gráficos da distribuição anual do Kc, foram comparados os valores obtidos para Recife e Petrolina, em que se observou que a cidade de Petrolina dispõe de uma quantidade maior de dias de céu claro, decorrente da característica climática da região.

Este trabalho apresenta uma avalição da visão dos profissionais do setor de energia fotovoltaica em relação a importância da operação e manutenção destes geradores. Foram realizadas entrevistas estruturadas com quinze profissionais, tais como arquitetos, engenheiros e gerentes de projetos responsáveis por projetar, implementar e realizar pesquisas científicas com sistemas fotovoltaicos em Florianópolis e Uberlândia. Os pontos mais relevantes deste levantamento foram 20% dos entrevistados terem experiência com plantação de sistemas híbridos fotovoltaicos. Os profissionais entrevistados possuem boa experiência de trabalho com sistemas fotovoltaicos, média de 2,7 anos, comparados com os 5 anos de regulamentação da conexão deste tipo de gerador no sistema elétrico. O sistema flutuante foi indicado por 60% dos entrevistados como o mais complexo em se realizar manutenção. A segurança do trabalho foi um ponto abordado durante a entrevista, o sendo que 40% dos entrevistados indicaram que as usinas instaladas em telhado são os sistemas mais complexos para realizar a manutenção devido aos riscos associados a esta atividade em altura. Esta preocupação é extremamente pertinente ao se analisar os dados da Organização Mundial do Trabalho que aponta o Brasil como um dos líderes nas estatísticas de acidente no trabalho, sendo que 40% dos acidentes registrados são provenientes de atividades laborais em altura. A instalação de um sistema fotovoltaico é um processo que requer profissionais de diversas áreas da engenharia e arquitetura. A operação e manutenção destes geradores, demanda um grande conhecimento multidisciplinar necessário para o planejamento, entendimento dos procedimentos e suas respectivas periodicidades, necessárias para mantê-los funcionando adequadamente. Pode-se constatar que ainda carecem de uma visão macro de todas as etapas de projeto, implantação, monitoramento, operação e manutenção deste tipo de usina.

Calor de processo industrial representa uma grande parte da demanda energética das indústrias. Setores como têxtil, bebidas e alimentos demandam por volta de um terço de eletricidade e, o restante, calor de processo. Simulações utilizando o software System Advisor Model (SAM) foram realizadas para obtenção do sistema solar termoelétrico que visa atender à demanda energética de uma planta de processamento de leite instalada em três localidades no Nordeste do Brasil com diferentes irradiações diretas normais (DNI). A análise financeira mostrou custos nivelados de calor (LCOH) entre 2,52 e 3,38 ¢/kWh-t para tubos evacuados e entre 5,95 e 11,67 ¢/kWh-t para tubos com ar. Os LCOH com uso de tubos evacuados são comparáveis ou até melhores que os custos de calor a partir de gás natural nos EUA e Europa. Já o custo nivelado de eletricidade (LCOE) para o ciclo de Rankine a vapor e ciclo orgânico de Rankine ficaram entre 0,23 e 0,31 US$/kWh-t para os tubos com vácuo e entre 0,63 e 2,73 US$/kWh-t para aqueles com ar. Os LCOE obtidos para tubos evacuados e ORC são comparáveis aos das plantas de grande porte existentes atualmente, mas ainda altos comparados a outras fontes renováveis.

Background: Polymorphonuclear neutrophils (PMN) are the only leucocytes that are competent to produce large amounts of reactive oxygen species (ROS) to kill phagocytized bacteria. In leukaemia, we hypothesized this bactericidal function might be hampered. Aim and Objectives: The goal of this study was to assess respiratory burst activity of PMN in leukaemia compared with non-leukaemic control subjects. We assessed the respiratory burst function of PMN as an effective defence against pathogens in leukaemia and control subjects. Materials and Methods: Peripheral blood samples were collected from leukaemia and control subjects (30 in each case) in lithium heparin anticoagulant containers. Our study cases were 30 leukaemia belonging to different subtypes (AML=12, CML=12, ALL=4 and CLL=2), 22 males and 8 females age range from 2.5–63 years (M±SEM, 28.0±3.4 years); the controls were 26 males and 4 females, age range from 17–53 years (M±SEM, 31.1±1.5 years), respectively. The respiratory burst activity was assessed using the nitroblue tetrazolium (NBT) dye reduction test on stimulated and un-stimulated PMN in leukaemia and control groups. Results: The cells purity in leukaemia was >99% using Turk's solution and cells viability was >95% by Trypan blue dye exclusion test. The respiratory burst activity of PMNs showed a statistically significant increase (P<0.05) in controls compared with leukaemia subtypes. Similarly, comparison within leukaemia subtypes indicates a statistically significant increase (P<0.05) RBA in CML compared with AML, ALL and CLL, respectively. Conclusion: the respiratory burst activity of PMNs in leukaemia is variable with enhanced activity in CML subjects, while depressed in AML, ALL and CLL subtypes; suggesting impaired bactericidal capacities of PMNs in these diseases.

Целью исследования было изучение комплекса ганглиозных клеток сетчатки у пациентов с болезнью Альцгеймера (БА). Обследовали пациентов с БА, с легкой и умеренной степенью нарушения памяти, и здоровых добровольцев соответствующего возраста. У пациентов с БА в 33,3% случаев определялась легкая деменция, в 62.6% случаев – умеренная деменция и в некоторых случаях – умеренные нарушения когнитивных функций. Пациентам измеряли остроту зрения, внутриглазное давление, оценивали по краткой шкале оценки психического статуса (КШОПС) и проводили спектральную оптическую когерентную томографию. Было вывялено снижение зрения и внутриглазного давления, а также снижение баллов по КШОПС у пациентов с БА. Выявлено, что снижение толщины комплекса ганглиозных клеток (КГК) у пациентов с БА чаще встречается в нижнем височном сегменте (84.4%), нижнем носовом (82.2%) и нижнем сегменте (71.1%). Обнаружено достоверное увеличение значений фокальной и глобальной потери объема клеток ганглиозного слоя в сравнении с контролем.

The aim of the work was to determine the thickness of the complex of retinal ganglion cells in patients with Alzheimer's disease (AD). The study involved patients with AD with cognitive impairment in mild and moderate severity and healthy volunteers at corresponding ages. It was determined mild dementia in 33.3%, moderate dementia in 62.6% of cases, and mild cognitive impairment several times. The visual acuity of the eye, intraocular pressure, spectral optical coherence tomography, and evaluation on the MMSE scale were measured in the study. It was revealed that visual acuity and intraocular pressure, as well as points on the MMSE scale in patients with AD, were reduced compared with the control group. A decrease in the thickness of the ganglion cell complex in patients with AD was more common in the inferotemporal segment (84.4%), inferonasal (82.2%), and inferior segment (71.1%). The index of focal and global loss of ganglion cell volume was significantly increased.

Published: July 2023

The background of the creation of this work is the introduction of the nuno felting technique to farmers and craftsmen in the village of Bomerto, Wonosobo to utilize the wool of the Wonosobo Sheep which is exported abroad. This happens because Indonesia has not been able to process wool into a work that has high value and is useful for society. From these problems, it is possible to create new works that will add value to the renewal to encourage the development of textile technology and as another alternative in processing Wonosobo Sheep's wool with the nuno felting technique. The problem in this design is how to apply the nuno felting technique to Wonosobo Sheep wool and organza silk which can be realized in the form of a scarf with geometric motifs. In solving this design problem strategy using Gustami's theory, namely by way of exploration, design, and embodiment by considering aspects of observation, visual studies, product comparisons and the trial phase. The result of this design is a scarf product with the nuno felting technique in the form of 7 designs and 2 scarf products measuring 140 x 50cm. It is hoped that the Nuno felting technique can create functional products and look to the government to advance the creative economy in society.
Digital Pedagogy. Definition and Conceptual Area
Authors:   University of Bucharest, Istrate Olimpius
Published: July 2023

Is there a digital pedagogy, as a distinct domain, different from general pedagogy and from any other pedagogy? If so, what are the aims, object of study, specific methods and principles of digital pedagogy? What is digital pedagogy and how does it articulate with education sciences? These are the questions of the beginning stage of an emerging area within the education sciences, where practice challenges us to expand the existing body of knowledge corpus and pedagogical methods. The article contributes to the contextualization of the set of information, experiences and scientific knowledge, conditions, relationships, meanings orbiting the phrase “digital pedagogy”. The term itself has been used for over 10 years – the first dedicated articles being from 2011, with elements of digital proto-pedagogy in 2004: Latham, apud Fyfe – but absorbing a series of much older concepts and practices, sometimes in a new way.
