Authors: Silva Alecsandro Marian da , Alves Tânia Rozimar , Junio Samuel dos Santos
Published: June 2024

O papel do Estado na promoção do desenvolvimento sustentável, destacando sua responsabilidade constitucional e seu impacto como grande consumidor de bens e serviços. Com base nesses princípios, a pesquisa se concentra nas práticas sustentáveis adotadas pelo Tribunal Regional Eleitoral de Rondônia (TRE/RO), buscando avaliar seu alinhamento com os Objetivos de Desenvolvimento Sustentável (ODS) da ONU. Os objetivos da pesquisa incluem descrever as ações sustentáveis do tribunal, identificar conceitos aplicados à sustentabilidade no poder judiciário e analisar as iniciativas desenvolvidas pelo TRE/RO entre 2020 e 2023. Destaca-se a importância da abordagem TBL (Triple Bottom Line), que considera não apenas os aspectos econômicos, mas também os impactos sociais e ambientais das atividades empresariais. Para o alcance dos resultados propõe-se uma pesquisa exploratória e descritiva adotando um método qualitativo, embasado na análise de documentos institucionais, relatórios de sustentabilidade e normativas internas do TRE-RO, visando uma compreensão contextualizada das ações implementadas pelo tribunal, suas motivações, desafios e resultados alcançados. O Plano de Logística Sustentável (PLS) do Tribunal é uma estratégia que visa promover ações sustentáveis na gestão de recursos em organizações. Ele abrange diversas áreas, como consumo consciente, redução de desperdício, economia de energia e uso eficiente de materiais. Dentre os principais resultados do TRE/RO destacam-se o consumo zero de copos descartáveis nos anos de 2022-2023, a diminuição expressiva das impressões a partir de 2020, e em 2022 foram coletados e encaminhados para o processo de reciclagem ou reaproveitamento o total de 16.264,74 Kg (16 toneladas) de materiais variados.  Em 2023, o Tribunal coletou para reciclagem ou reaproveitou cerca de 33 Kg (33 toneladas) de materiais, além de coletar 238 brinquedos para doação. As ações empreendidas pelo Tribunal Regional Eleitoral de Rondônia (TRE/RO) em prol da sustentabilidade não apenas refletem um compromisso sério com a preservação ambiental e o uso responsável dos recursos, mas também estão alinhadas com os Objetivos de Desenvolvimento Sustentável (ODS) estabelecidos pela ONU. Essas ações não são apenas louváveis em si mesmas, mas também são um exemplo inspirador para outras instituições e organizações, demonstrando que é possível conciliar eficiência operacional com práticas sustentáveis.

Published: June 2024

Biological disease control has become popular in recent years and has established itself as a viable alternative to chemical control. However, the efficiency of biological control can be limited by the application technology. Thus, the objective of this work was to evaluate the compatibility of Trichoderma harzianum with three commercial herbicides. The fungus was incubated in culture medium supplemented with doses of three commercial herbicides and incubated for 4 days. The CI50 (concentration capable of inhibiting 50% of the mycelial growth of the fungus) was determined for each herbicide and compared with the recommended doses for field application. All herbicides tested reduced mycelial growth, with CI50 lower than the recommended doses. The data suggest low compatibility between T. harzianum and the tested herbicides.

Globalização, políticas públicas curriculares e o avanço de um modelo hegemônico de currículo escolar na educação brasileira
Authors: Prado Mariana Camargo do , Rocha Marcelo Augusto , Veiga Léia Aparecida
Published: June 2024

Este estudo tem por recorte temático o paradigma norteador dos currículos escolares ao final do século XX, quando estes passaram a ser guiados na direção da construção de uma identidade global que é homogeneizante e isomorfa a nível mundial. Objetivou-se refletir sobre o currículo escolar a partir das conformações hegemônicas que regem o sistema-mundo globalizado lançando luz a padronização curricular a nível global e aos agentes beneficiados por padronização no Brasil. Por tratar-se de uma pesquisa de abordagem qualitativa, o corpus da análise partiu de uma revisão bibliográfica e documental sobre o tema, utilizando os Parâmetros Curriculares Nacionais e a Base Nacional Comum Curricular como documentos norteadores. Verificou-se que a globalização promove um novo arranjo organizacional que interfere diretamente na relação entre currículo e espaço escolar, pois transfere o poder de decisão sobre a formulação dos conhecimentos escolares para agentes econômicos na escala global. Conclui-se que o currículo se torna desterritorializado da escola, submetido à determinações que são externas ao ambiente escolar, e que servem, sobretudo, à lógica de acumulação do capital.
DYE 10-N-NONYL ACRIDINE ORANGE AS A FLUORESCENT INDICATOR OF THE ACTION OF THE ANTISEPTIC OCTENIDINE ON THE MEMBRANES OF RHODOBACTER SPHAEROIDES CHROMATOPHORES

Published: June 2024

Increasing volumes of produced antiseptics and disinfectants, which are widely used in medicine, veterinary medicine, the food industry and everyday life, can create a serious environmental problem after use. Previously, under the infl uence of micromolar concentrations of a number of antiseptics, we identifi ed disturbances in the functioning of photosynthetic membranes and phototransforming pigment-protein complexes isolated from them in various representatives of photosynthetic organisms. In this work, to determine the sensitivity of photosynthetic membranes to the action of the cationic antiseptic octenidine, we used chromatophores of the purple nonsulfur bacteria Rhodobacter sphaeroides, labeled with the fluorescent dye 10-N-nonylacridine orange (NAO). It was shown that the binding of NAO to chromatophores is accompanied by a shift in the dye emission maximum from 525 to 640 nm. The “red” fluorescence of NAO associated with chromatophores turned out to be sensitive to the effect of increasing concentrations of octenidine on photosynthetic membranes. We have found antiseptic concentrations which led to the degradation of chromatophore structures and change in the NAO aggregative state. It can be detected by an increase of “green” fluorescence in the emission spectra of the dye. The properties of NAO as a fluorescent indicator of the functional state of photosynthetic membranes and possible changes that can occur in such systems under the influence of a cationic antiseptic are discussed.
NEW FACTORS AND PREREQUISITES FOR THE ECONOMIC ZONING OF RUSSIA
Authors: BAKLANOV P.YA.
Published: June 2024

Economic zoning in the USSR was focused on the practical tasks, first of all, comprehensive planning for the long-term development of the national economy. In the 1990s, with the beginning of radical political and economic transformations in the country, the economic zoning lost its practical significance. However, even under market economy, the objective processes of territorial division of labor, industrial and technological connectivity of enterprises and companies still persist, as well as, agglomeration processes. Recently, new factors and prerequisites for the growing importance of economic zoning have emerged, such as the restoration of multilevel strategic planning, changes in the geopolitical situation of the country’s development and the need to achieve industrial and technological sovereignty. With this background it seems that the need to take into account the objective processes of complex formation and district formation, and to perform a new multi-level economic zoning of Russia on this basis sharply increases. The article provides a possible scheme of seven large economic regions and 22 mesorayons. The main links of production and technological chains and priority activities are identified for the large regions. Such zoning could be useful for the long-term planning of sustainable development of the country and its regions.

Published: June 2024

The Community Service activity is motivated by the activities of the women in Libersa Tambun housing complex regarding investment management. One of the regular activities they engage in is arisan, a financial system that lacks legal regulations and solely follows traditional practices in the community. The mothers in Libersa housing complex have been conducting arisan activities without understanding whether the arisan transactions they have been participating in comply with Islamic principles or not. From an accounting perspective, arisan can be seen as a form of debt, but in Islamic principles, arisan can be conducted as long as it does not involve usury (riba). Mentoring on the concepts of accounting in arisan and Islamic principles becomes the method employed in the Community Service activity, with the aim of helping the mothers understand the differences between investment and arisan from the perspective of Islamic accounting. The results of the activity indicate that the participants comprehend the concept of arisan based on Islamic principles and are able to perform accounting records for transactions within arisan.

Storage Class Memory: Avanços e Limitações em Direção às Memórias Universais
Authors: Laks Pedro Ferro , Francesquini Emilio
Published: June 2024

Recentemente vem chamando a atenção o avanço nas pesquisas de novas tecnologias de memória chamadas de memórias emergentes, memórias persistentes ou Storage Class Memory, (SCM). Nesse texto discutimos as limitações e dificuldades para a criação de uma memória universal que substituiria toda a hierarquia de memórias por uma única memória. As SCM se aproximam das características necessárias para a criação de uma memória universal, mas ainda não as satisfazem completamente. Assim, as SCM podem pragmaticamente serem vistas como uma adição à hierarquia de memória atual, substituindo ou trabalhando em conjunto com as tecnologias SSD, DRAM e SRAM. Neste texto, exploramos o estado atual das SCM e discutimos sua evolução, com o objetivo final de reduzir a latência de memória para a CPU.

The Phenomena of “Doing Family” in a Migrant’s Experience
Authors: Ferrante Lorenzo
Published: June 2024

The contribution is focused on the immigrant’s re-shaping identity in the integration process through the phenomena of the “doing family” or “to continue to be a family.” This analysis looks at the relationships between immigrants, the role of family in migration and integration processes, and the challenges of managing change when people from different cultures, values, and languages live together. The basic assumption is that immigrants who arrive in a foreign country continue their lives as protagonists of their lives, seeking their authentic identity through the government of their daily practices, oscillating between defending traditions, and pushing innovation, adhering to the life models of the host society.
Optimal Stochastic H∞ Controller Synthesis via LQR Theory
Authors: Kuan Foo Yung , Chai Soh Yeng
Published: June 2024

Existing published works on H∞ and mixed H∞/H2 control generally solve the problem via game theory and saddle-point solutions. We provide an alternative solution via the stochastic LQR approach. Specifically, we consider the problem of H∞ state regulation problem for continuous-time systems which are subjected to both energy-bounded deterministic disturbances and stochastic white noises, and uncertain initial system state x(0) satisfying E{x(0)} = 0 and E{x(0)x(0)T} ≤ X0. We derive feedback laws which minimize sup||w(t)||2 ≤ 1E{||Π1/2x(t)||T2 + ||R1/2u(t)||T2}, where Π and R are positive-definite weight matrices. We further demonstrate how the approach may be extended to solving the robust stochastic LQR control with uncertainty in the system A matrix.
Channel Fading Models for 5G and 6G
Authors: Olyaee Maryam , Hashemi Hadi , Manuel Romero Jerez Juan
Published: June 2024

As communication technologies evolve, existing channel models need to be improved as new spectral bands, environments, and the use cases present propagation characteristics that are not properly captured by the well-known classical models. Small-scale signal fading, due to multipath propagation and the relative movement between transmitter and receiver, is one of the most important propagation effects in a wide range of wireless scenarios. Accurate modeling of this phenomenon in the millimeter-wave band has become particularly important due to its foreseen use in the 5G standard of cellular networks and beyond. In this chapter, we review several current channel models for new generations of wireless communication systems. These channel models consider different propagation mechanisms, such as specular (dominant) waves, multicluster reception, and signal fluctuations, and are studied based on their applications in both line-of-sight (LOS) and non-line-of-sight (NLOS) links.

Bialystok and Hakuta claim that “children are better second language learners than adults because their brains are specially organized to learn language” (p. 176). Studies still have debates regarding the optimum age for acquiring a second language and the effect of mother tongue on the fluency of second languages. The researcher conducted this study to investigate the effect of the Arabic mother tongue on Arab immigrants’ fluency in using English as a second language in the United States. The researcher used primary resources, interviewing 22 Arab immigrants in the United States, and secondary resources through literature review relevant to language acquisition. The data analysis of this study reveals that Arab immigrant children and adults encounter various challenges in using English in communicative situations. The study provides some recommendations for raising bilinguals at home.
Nanoemulsions: A Recent Drug Delivery Tool
Authors: Changediya Vaibhav
Published: June 2024

The use of nano/sub-micron particles in food, cosmetic, and pharmaceutical technology is becoming more and more popular. In particular, this interest has been growing in tandem with improved stabilization and emulsification methods. High-energy and low-energy spontaneous emulsification techniques are the two primary categories of nanoemulsion preparation techniques. Stability ranging from a few hours to years is influenced by important characteristics related to preparation procedures and components used. Nanoemulsions do not worry about issues like creaming, coalescence sedimentation, and flocculation because of their small droplet size. Ostwald ripening for them is the primary destabilizing process, though. This chapter provides a thorough overview of nanoemulsions including an explanation of their preparation techniques and assessments.
Measuring the Poverty of Herder Households in Mongolia
Authors: Gombodorj Ganchimeg , Pető Károly
Published: June 2024

Mongolia faces difficulties in eradicating rural poverty, the same as other developing countries in the World. The selection of appropriate measurement is an essential prior step with regard to the complexity of poverty types and specifications. The most widely used poverty measuring methods are Income/cost Per Capita (IPC) per day and multidimensional poverty index (MPI). In the case of nomadic herder households in Mongolia, a livestock number is used as a proxy indicator to measure livelihood and poverty. Considering that, a herder household with less than 200 animals is considered poor, in general principle. This study uses a survey of 350 herder households, divided into three livelihood groups based on the number of livestock following the World Bank methodology; three groups are namely poor, lower wealthy and wealthy herder households. The livelihood of households was measured using IPC and MPI-3 methods, and the study results suggest that the MPI-3 method is not entirely appropriate to measure the herder household’s poverty and needs to adjust and add some indicators. According to their difference, part-time and periodic herders should be identified separately from full-time herders regarding measuring and studying livelihood and poverty levels.

Published: June 2024

Biochar, a carbonaceous material produced through pyrolysis of organic matter, has garnered attention for its potential to enhance soil fertility, structure, and overall health. However, its effects on soil-dwelling insects remain a subject of considerable interest and debate. This chapter critically examines the current state of knowledge regarding the interactions between biochar applications and soil-dwelling insects, encompassing diverse aspects such as alterations in insect community composition, population dynamics, behavioral changes, and potential mitigation of infestations. Through an exploration of empirical studies and theoretical frameworks, it aims to elucidate the intricate relationships between biochar amendments and soil insect ecology.

Sickle cell disease (SCD) is an autosomal recessive hemoglobinopathy leading to hemolysis, increased endothelial adhesion, inflammation, and vasculopathy. While most children with SCD have normal pulmonary function, lung capacity and expiratory flows are lower compared to age- and racially matched controls. Airway obstruction dominates in children, with restrictive ventilatory defects becoming more prevalent in adolescents and young adults. Decreased pulmonary function, physician-diagnosed asthma, airway hyperresponsiveness, wheezing, and sleep-disordered breathing are associated with more frequent episodes of acute chest syndrome and vaso-occlusive crisis. Chronic lung disease, thromboembolism, hypoxemia, and sleep-disordered breathing are associated with the development of pulmonary hypertension and ventricular dysfunction which carry significant morbidity and mortality risk in adults. Most treatments for cardiopulmonary complications of SCD are based on guidelines developed for the general population. Although most guidelines do not recommend routine screening of asymptomatic children, patients with cardiopulmonary symptoms should be monitored and treated by subspecialists in a multidisciplinary setting. Disease modifying treatments such as hydroxyurea are attenuating some of the cardiopulmonary complications in SCD. More studies need to be done to assess the effects of newer disease modifying treatments targeting hemolysis and decreasing endothelial adhesion.

Published: June 2024

With the ever-growing complexity of different assets in a factory, the main focus of predictive maintenance solutions has shifted from model-based approaches to data-driven and hybrid approaches. This shift as a result highlights the importance and the inevitable impact of data, data quality, model maintenance, and model interpretability on the performance and acceptability of these predictive maintenance approaches in industry. In this chapter, the hurdles for developing effective predictive maintenance solutions for original equipment manufacturers (OEMs) and small and medium-sized enterprises (SMEs) with different levels of digitalization are introduced. Furthermore, it is discussed how to choose a suitable strategy for developing a predictive maintenance model, given the different constraints in the availability of data and the requirements of the customer.
Role of Macrophages in Promoting Inflammation and Fibrosis in Systemic Sclerosis
Authors: Lopez Garces Sandra , Pan Liyang , Stratton Richard
Published: June 2024

Systemic sclerosis (SSc) is a severe autoimmune disease characterized by chronic inflammation, vascular damage and fibrosis. The hallmark clinical manifestation is fibrotic skin thickening; however, the clinical outcome is determined by the extent of internal organ fibrosis. Macrophages, integral to the innate immune system, play a crucial role in phagocytosing invading pathogens and efferocytosis of apoptotic cells, while also contributing significantly to tissue homeostasis and repair. These highly adaptable cells, particularly in the M2-like polarization state, have been associated with a pro-fibrotic environment, implicated in various fibrotic disorders as well as cancer invasion. In SSc, these cells may be dysfunctional, having the potential to produce inflammatory and pro-fibrotic cytokines, recruit other inflammatory cells and stimulate fibroblast differentiation into myofibroblast, thus promoting extracellular matrix (ECM) deposition and fibrosis. Accordingly, we hypothesize that abnormally activated macrophages have a central role in SSc, promoting inflammation and fibrosis, and driving the disease process.

Published: June 2024

The intestinal protozoan parasites pose serious health concerns, infecting more than one billion individuals every year and mainly causing diarrhea in infants and adults. Main pathogens include Giardia intestinalis, Entamoeba histolytica, Cyclospora cayetanensis, and Cryptosporidium spp. causing giardiasis, amoebiasis, cyclosporiasis, and cryptosporidiosis, respectively. The drug arsenal to treat these diseases is limited (<25 drugs are in clinical use) for the treatment of all protozoal infections. The existing treatment options are decades of years old (discovered in 1930–1980s) and have limitations such as low therapeutic index, toxic side effects during long-term treatment, and drug resistance. Therefore, urgent renewed drug discovery efforts are needed to tackle these neglected protozoal diseases. This chapter discusses the current status of treatment options and their limitations, along with current drug discovery efforts. We conclude that the knowledge gained in the genomic and post-genomic era should be appropriately harnessed to accelerate the futuristic drug discovery process in this field.
