Published: August 2024

Este trabalho apresenta a proposição de um Curso de Graduação em Licenciatura em Educação de Pessoas com Deficiência Visual, tomando a Pedagogia Crítico Libertadora de Paulo Freire como norteadora e a Educação em Direitos Humanos como eixo articulador do curso. Estruturado em cinco eixos - Fundamentos da Educação, Educação Especial com foco na Deficiência Visual, Estágio Supervisionado, Trabalho de Conclusão de Curso e Disciplinas Optativas - esta proposta está comprometida em consolidar a interrelação teoria e prática no processo de formação docente, com a participação cidadã e o combate a todas as formas de violação dos Direitos Humanos. Empenhada em formar professores comprometidos com uma formação humana, transformadora, emancipatória e integral, e respeitando as necessidades específicas e incentivando as potencialidades dos alunos com Deficiência Visual, o curso justifica-se pela complexidade que se revela na aprendizagem dessas pessoas e pelos impactos e implicações funcionais ocasionados por essa deficiência. Sua relevância pauta-se numa proposição precursora no cenário educacional brasileiro e no preenchimento de importante lacuna da formação de professores, uma vez que não há curso em nível superior direcionado exclusivamente à formação docente que focalize o atendimento às necessidades educativas específicas do aluno com Deficiência Visual. Essa proposta resultou de uma pesquisa que investigou o conceito de Tecnologia Assistiva presente nos Projetos Pedagógicos dos Cursos Técnicos de Nível Médio ofertados pelo Instituto Benjamin Constant. Estes projetos foram analisados em seu conteúdo e os achados mostraram não apenas que o conceito de Tecnologia Assistiva se restringia especialmente a recurso, como também que a formação oferecida naqueles cursos era generalista e insuficiente para o atendimento das particularidades do público-alvo atendido, gerando prejuízos no processo de aprendizagem dos alunos com Deficiência Visual.

Authors: Isiya Sani , Salisu Baha'uddeen
Published: August 2024

Study’s Novelty/Excerpt

This study offers an approach to sustainable agriculture by isolating and identifying phosphate-solubilizing Pseudomonas species from the rhizosphere soil of Wagini ward, Katsina state, for the production of biofertilizers.
The research highlights the significant phosphate-solubilizing activity of these native strains, which enhances phosphorus availability to plants through the secretion of organic acids and enzymes.
By demonstrating the positive effects of these Pseudomonas-based biofertilizers on maize, beans, and millet, this study provides valuable insights into the development of eco-friendly, cost-effective biofertilizers tailored to local agroecosystems, thereby promoting sustainable agricultural practices in Nigeria.

Full Abstract
The utilization of biofertilizers holds promise as a sustainable approach to enhance soil fertility and crop productivity while reducing reliance on chemical fertilizers. Beyond nitrogen, phosphorus is integral to various aspects of plant metabolism, including cell division, growth, development, sugar breakdown, and nuclear transport. The present study focuses on isolating Pseudomonas as phosphate-solubilizing bacteria from the rhizosphere soil to produce biofertilizer. Ten samples of rhizosphere soil samples were collected from agricultural fields in Wagini ward, Batsari Local Government area, Katsina state. The isolation and identification of Pseudomonas species from the soil samples were conducted using standard microbiological techniques, followed by screening for plant growth-promoting traits (phosphate solubilization). Subsequently, selected Pseudomonas species exhibiting robust phosphate solubilization were assessed for their efficacy in biofertilizer production, after which the produced biofertilizer was tested on maize, beans, and millet. The formulated biofertilizers demonstrated remarkable positive effects on the tested crops’ growth compared to those that were not treated with the Pseudomonas-based biofertilizer after seven days of cultivation under controlled conditions. The results of this study revealed that the isolated Pseudomonas strains exhibited significant phosphate-solubilizing activity. This indicates their potential to release phosphorus from insoluble forms, making it more accessible to plants. The solubilization activity was attributed to the secretion of organic acids and enzymes by the Pseudomonas strains, which can dissolve complex phosphates. This study underscores the importance of tacking native microbial resources for the development of eco-friendly and cost-effective biofertilizers tailored to local agroecosystems, thereby contributing to sustainable agricultural intensification and food security in Nigeria.

Published: August 2024

Study’s Novelty/Excerpt

This study presents insights into the cost-effective production of amylase enzymes using sugar cane bagasse as a substrate, showcasing a significant advancement over traditional synthetic starch substrates.
By optimizing production parameters such as incubation time, substrate and inoculum concentrations, pH, and temperature, the research demonstrates the superior amylase yield of Aspergillus niger, Aspergillus flavus, and Fusarium spp. under specific conditions.
This work not only highlights the potential of using waste materials for industrial enzyme production but also emphasizes the need for further exploration of the isolates' identities and the industrial applications of the extracted enzymes.

Full Abstract
Amylases are hydrolytic enzymes produced by some microorganisms and utilized in the hydrolysis of starch.  This study aimed to determine the ability of certain fungal isolates isolated from wastes to synthesize the amylase enzyme utilizing synthetic soluble starch and sugar cane bagasse as substrates.  Aspergillus niger, Aspergillus flavus, and Fusarium spp., previously identified to have amylolytic activity, were used for the research.  The submerged fermentation process was used to produce amylase, with basal medium and sugar cane bagasse as substrates.  The incubation time, substrate and inoculum concentrations, pH, and temperature were all optimized.  The dinitrosalicylic acid reagent (DNS) technique was used to determine the activity of the amylase generated.  Initial production of amylase using soluble starch (20 g (w/v)) as substrate at room temperature and pH 7.0 shows that all the isolates produce amylase better when their concentration (3%) is high but have different incubation periods of 96 hr for Aspergillus niger (8.65±0.21 U/mL/minutes) and Fusarium spp (7.15±0.07 U/mL/minutes), while Aspergillus flavus (7.30±0.14 U/mL/minutes) requires an extended incubation period of 144 hr to produce the product.  Further production using sugar cane bagasse and optimization of production parameters of the isolates reveals that Aspergillus niger (4.35±0.07 U/mL/minutes) has an optimum incubation period of 120 hours, an inoculum concentration and substrate concentration of 2% each, and a pH of 6, Aspergillus flavus (6.40±0.28 U/mL/minutes) has an optimum incubation period of 144 hours, with inoculum and substrate concentration of 3% each at neutral pH, Fusarium spp (6.80±0.28 U/mL/minutes) has an optimum incubation period of 168hr., inoculum concentration of 3%, substrate concentration of 2% and a neutral pH-7 and all the isolates have their best yield at temperature of 30oC.  In conclusion, using cheap and readily available sugar cane bagasse can be a more cost-effective option for expensive synthetic starch substrates used in amylase synthesis.  The study suggests further investigation into the isolates' identities and the extracted enzyme's industrial application.

Study’s Novelty/Excerpt

This study evaluates Interleukin-18 (IL-18) as a potential biomarker for COVID-19 by comparing its serum levels in COVID-19-positive patients and healthy controls.
The research uniquely identifies significantly elevated IL-18 levels in COVID-19 patients, demonstrating a strong statistical association with the infection (t value 6.16, p <0.00010).
These findings underscore the potential of IL-18 in the prognosis and clinical management of COVID-19, offering new insights into its role in the disease's pathophysiology and its utility as a biomarker.

Full Abstract
Coronaviruses have a history of causing severe outbreaks with life-threatening consequences, including Severe Acute Respiratory Syndrome (SARS), Middle East Respiratory Syndrome (MERS), and the recent coronavirus disease 2019 (COVID-19).  COVID-19 first broke out in Wuhan (China) in December 2019).  The disease was later declared a pandemic, and so far, more than 222 countries have been affected, with over 771 million confirmed cases and total deaths of over 7.05 million.  Some immunological markers were reported elsewhere as directly related to COVID-19 pathophysiology and stand a chance to be considered biomarkers.  Interleukin 18 (IL-18) is a proinflammatory cytokine and a member of the interleukin-1 family, produced by macrophages at the early stage of viral infections.  However, aberrant IL-18 production can lead to severe pathological injury.  Hence, there is a need to assess the feasibility of interleukin -18 as a biomarker for COVID-19.  Forty-five individuals diagnosed with COVID-19 and 45 healthy controls screened using a COVID-19 antigen rapid test kit and confirmed by one-step real-time PCR were recruited for this study.  Blood samples were collected from the patients and controls, and the samples were analyzed for IL-18 using the ELISA technique.  This study revealed a higher level of IL-18 in COVID-19-positive patients (206.42 ± 13.2 pg/mL) compared to the control group (97.96 ± 14.4 pg/mL).  Serum level IL-18 was statistically associated with COVID-19 infection (t value 6.16, p <0.00010).  The study demonstrates the importance of IL-18 in the COVID-19 cohort, inferentially implying its potential in the prognosis and clinical management of COVID-19.

The findings suggest that V. amygdalina could be a promising candidate for developing new anti-Salmonella treatments, contributing to the management of salmonellosis in underdeveloped nations.

Full Abstract
Salmonellosis is becoming a common illness in underdeveloped nations, and specifically, typhoid fever is a major public health concern due to its high likelihood of recurrence. Salmonella has become resistant to numerous drugs, making it necessary to look for effective novel antibacterial substances from alternative sources, including plants. The antibacterial activity of Vernonia amygdalina (bitter leaves) extracts was assessed in this study against ten (10) Salmonella species clinical isolates. The bitter leave was cleaned, dried, and ground into powder. The phytochemical content of the leaves was extracted using ethanol and aqueous solvent; the extracts' antibacterial activity was tested against clinical isolates of Salmonella. Alkaloids, cardiac glycosides, saponins, steroids, tannins, and glycosides were among the constituents present, according to the phytochemical analysis. The highest zone of inhibition was 11 mm for the ethanolic extract at 100mg/mL concentration demonstrated against SS 4 isolate, while 9 mm was the highest zone of inhibition for the aqueous extract at 100mg/mL concentration against SS 6 isolate. For both extracts, the Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC) of all Salmonella isolates tested were found at 50 mg/mL and 100 mg/mL concentrations, respectively. V. amygdalina has antibacterial activity against Salmonella and should be investigated further for potential application in developing anti-Salmonella medications and managing salmonellosis.
Bacterial Bisorption as an Approach for the Bioremediation of Chromium Contaminated Soils: An Overview
Authors: Fardami Aminu Yusuf , Abdullahi Sherif
Published: August 2024

Study’s Novelty/Excerpt

This study presents comprehensive overview of the roles of various bacterial genera, including Alcaligens, Achromobacter, and Bacillus, in the biosorption of chromium from contaminated soils, highlighting specific factors influencing biosorption efficiency.
It uniquely addresses the optimization of environmental conditions such as pH, temperature, and nutrient availability to enhance large-scale biosorption processes, bridging gaps noted in previous literature regarding the scalability of bacterial biosorption.
Additionally, the manuscript underscores the necessity for further research in biotechnology and molecular engineering to fully harness the potential of bacterial biosorption for chromium remediation, presenting a forward-looking perspective on advancing this bioremediation strategy.

Full Abstract
Chromium possesses detrimental effects on the health of both plants and animals.  Biosorption is a process where biological materials (bacteria, fungi, algae, or agricultural waste) are used to remove pollutants from contaminated sites.  Conventional methods of remediating heavy metal-contaminated soils, such as excavation and chemical treatment, are expensive and disruptive, making them less desirable.  Factors influencing bacterial biosorption efficiency are promising approaches involving bacteria to remove heavy metals such as Chromium, lead, nickel, cadmium, arsenic, etc., from contaminated soil.  Some bacterial genera involved in biosorption include Alcaligens, Achromobacter, Acinetobacter, Alteromonas, Arthrobacter, Burkholderia, Bacillus, Enterobacter, Flavobacterium, and Pseudomonas.  These bacteria can adsorb heavy metals such as Chromium and biotransform them into less toxic forms.  Some factors influencing bacteria biosorption efficiency include pH, temperature, concentration, bacterial surface compositions, metal ion characteristics, and soil composition.  Challenges associated with using bacteria for biosorption, as outlined in previous literature, include the slowness of the process and the fact that it may not be suitable for large-scale application, even though many other authors have proven its applicability on a large scale.  Also, the key quality needed from the bacterial biosorbent must be tolerating the heavy metals.  Another area of focus in current research is optimizing environmental conditions, such as temperature, pH, and nutrient availability, to achieve a more efficient biosorption at a larger scale.  This overview highlighted the roles of bacteria in the biosorption of chromium heavy metal as a strategy for the bioremediation of Chromium contaminated soil.  Conclusively, bacterial biosorption has a great potential for use in Chromium- contaminated soil remediation, and more research is needed to fully realize this potential, especially in biotechnology and molecular engineering.
Performance of Agriculture Extension Services under Local Government Authorities in Tanzania: A Review
Authors: John Miyekelo Daudi Sebastian Severin Mosha
Published: August 2024

East African countries referred to have the effective extension system in Africa. However, the agriculture sector has not shown significant improvement in production and bettering peoples’ lives in rural areas. In Tanzania, agricultural extension system remains almost entirely financed by the public sector represented by the government through the Ministry of Agriculture. Extension services provided by the Government of Tanzania are publicly funded and, thus, free for farmers employing several extension systems and approaches including the gradual improvement in farming methods, the transformation approach, the settlement scheme and the Training and Visit (T&V) system. Decentralization of extension services in Tanzania introduced with the aim of bringing services closer to farmers. However, the impact of decentralization of extension services in improving farmers’ lives has been perceived mostly with failure than with success. Additionally, performance of extension services in the country reported to be affected by numerous factors such as inefficient funding, poor organization at Local Government Authorities (LGAs), coordination and management, political interference environment, and weak linkage with research sector among others. In addition, the insufficient number of staff and poor infrastructures and facilities, government extension agents reach only 10% of the farming households, leading to dissatisfaction with rendered services among farmers. However, Government’s apparent commitment to policies and strategies in transforming the agriculture sector as it employs more than 70% of its population. Thus, recently, the central government provided motor bikes, iPad and soil scanners to all extension workers throughout the country. Hence, this review on the performance of agriculture extension services under local government authorities was conducted to articulate challenges facing the system and propose solutions to achieve the traditional ‘structural transformation’ whereby increasing agricultural production provides a platform for manufacturing and economic growth.

Published: August 2024

Este estudo, utilizando uma abordagem analítica, examinou as desigualdades enfrentadas pela população negra no mercado de trabalho durante a crise da Covid-19 na região do Nordeste do Brasil. Os resultados foram derivados da análise de dados coletados da Pesquisa Nacional por Amostra de Domicílios Contínua (PNAD-C) de 2020, que oferece uma ampla gama de informações socioeconômicas. Os resultados revelam que, embora o trabalho remoto tenha sido uma opção para alguns, ele excluiu muitos trabalhadores informais, exacerbando as disparidades preexistentes. Historicamente associada a piores indicadores sociais, a população negra enfrentou desafios adicionais devido à ausência de políticas eficazes que reconhecessem sua vulnerabilidade e promovessem a igualdade. A precariedade do trabalho, caracterizada por baixos salários e insegurança no emprego, foi um obstáculo significativo para essa população. Esses achados destacam a urgente necessidade de políticas que abordem as desigualdades estruturais no mercado de trabalho, promovendo inclusão e equidade para todos os trabalhadores.
Abstract: This study, using an analytical approach, examined the inequalities faced by the black population in the labor market during the Covid-19 crisis in the Northeast region of Brazil. The results were derived from the analysis of data collected from the Continuous National Household Sample Survey (PNAD-C), which offers a wide range of socioeconomic information. The results reveal that while remote work has been an option for some, it has excluded many informal workers, exacerbating pre-existing disparities. Historically associated with worse social indicators, the black population faced additional challenges due to the absence of effective policies that recognized their vulnerability and promoted equality. Precarious work, characterized by low wages and job insecurity, was a significant obstacle for this population. These findings highlight the urgent need for policies that address structural inequalities in the labor market, promoting inclusion and equity for all workers.

Published: August 2024

O fumo é o principal ativo da Região do Vale do Rio Pardo, no centro do Rio Grande do Sul, Brasil, movendo uma gigantesca cadeia produtiva que vai da agricultura, passado pelo beneficiamento, até chegar na exportação. Afora o caráter econômico, a produção de tabaco encontra na relação entre agricultores familiares integrados e empresas fumageiras integradoras seu elo mais frágil, induzindo a necessidade de estudos sobre o instrumento que liga um ao outro: o contrato de integração do Sistema Integrado de Produção do Tabaco, especialmente no que tange à classificação e consequente precificação do fumo. Utilizando-se de conceitos da Nova Economia Institucional é possível fazer a análise dos documentos contratuais e apontar alternativas que visam afastar as incertezas derivadas da última etapa produtiva para fortalecer a corrente integradora e verificar ganhos mais equilibrados às partes.
 
Abstract: Tobacco is the main asset of the Rio Pardo Valley Region, in the center of State of Rio Grande do Sul, Brazil, driving a gigantic production chain that goes from agriculture, through processing, to export. Aside from the economic nature, tobacco production finds its weakest link in the relationship between integrated family farmers and integrating tobacco companies, inducing the need for studies on the instrument that links one to the other: the integration contract of the Integrated Tobacco Production System , especially with regard to the classification and consequent pricing of tobacco. Using concepts from the New Institutional Economy, it is possible to analyze contractual documents and point out alternatives that aim to eliminate the uncertainties arising from the last production stage to strengthen the integrating chain and verify more balanced gains for the parties.

Authors: D. A. Otegen  , P. A. Tanzharykov  , N. S Suleimenov
Published: August 2024

This project presents a three-stage ball traction drive for electric vehicles, providing a remarkable speed ratio of 1/27. The geometric and kinematic aspects were carefully analyzed and calculated manually and then verified using Recurdyn software at different rotational speeds (100, 500, 1000 rpm). To prevent ball displacement at higher rotational speeds, a strategy involving a small gap between the intermediate balls was employed. For material selection, “Gear-Steel” was favored because of its high yield strength complemented by thrust bearing integration. The static equilibrium analysis was performed manually to provide insight into the relationship between the preload forces, which were further visualized using MATLAB graphs. The rolling efficiency for each stage was calculated separately. The design involved connecting three circular flanges using 18 pins and 18 heavy hex bolts. Modeling in ANSYS revealed a maximum equivalent stress of 737 MPa in the third stage. Finally, Solidworks helped optimize the topology, resulting in a noticeable 14.5 % reduction in overall volume. Keywords: Ball traction drive, gearbox, transmission system, continuously variable transmission, collision.

Тhe protection durability and effectiveness with paints and varnishes is largely determined by the surface preparation quality before painting. The labor-intensive work is surface preparing for applying paint and varnish coatings. The cost of surface preparing for painting can amount to 30–50 % of the painting work’s total cost, and in some cases even exceed the painting cost. Rust converters are becoming increasingly recognized in the equipment’s anti-corrosion protection practice. Their use makes it possible, in some cases, to simplify the technology of coloring, reduce labor intensity, improve working conditions, prevent environmental pollution, increase the durability of paint coatings and reduce their consumption. One of the promising types of raw materials for the development of a new rust converter is gossypol resin, which is a large-tonnage waste from the oil and fat industry. The problem of increasing the reliability and durability of structures, equipment and various equipment in the engineering industry has acquired particular relevance at the present stage of production development. For this aim, we have developed a rust converter composition based on gossypol resin. The subject of the study was the regularity and change in the process of restoration and application using a rust converter primer to increase the durability of metal structures of industrial equipment in the machine-building industry and agricultural technology. Conducting scientific research in the direction of expanding the range of rust converters to protect equipment from corrosion is an urgent and practical task. Keywords: gossypol resin, agricultural machinery, corrosion, rust converter, coatings, environment.

This study was conducted to gain a deeper understanding and analyze the factors that influence the community's borrowing behavior. It is hoped that in the future, the community will shift away from loan sharks and prefer existing banks, especially Islamic banks. The research methods used include direct interviews and the distribution of questionnaires to the villagers where the study was conducted. The sampling procedure in this study is the snowball sampling method with 68 respondents. The data analysis technique used is multiple regression analysis using SPSS version 2.2
The results of the study indicate that, simultaneously, the community's borrowing behavior is significantly influenced by Islamic financial literacy, needs, convenience, and collateral, as supported by the F-test result of 9.867. Meanwhile, partially, the factors of Islamic financial literacy and collateral have a significant negative influence on the community's borrowing behavior from loan sharks. The factor of needs has a significant positive influence on the community's borrowing behavior from loan sharks. The factor of convenience does not influence the community's borrowing behavior from loan sharks.

Hanging as a means to commit suicide is one of the most common methods known to mankind. But also, a common method to fabricate a murder. However, antemortem features at times are confirmatory but also confusing. This study aimed to establish the patterns of injuries to the neck structure in hanging cases. There were 228 cases of deaths caused by hanging. Hanging was most frequently reported in the 11-20 age group, comprising 30.22% (69 cases) out of 228 hanging deaths. Least seen among age group 81-90 i.e., 02 (0.87%). Above the age of 90, no deaths due to hanging were observed. Out of 228 deaths, 97 (42%) were females and 131 (57%) were males. Position of the knot was assessed, in 67 (29.3%) cases knots were on the left side of the neck, in 72 (31.5%) cases knots were on the back of the neck, in 75 (32.8%) cases knots were on right side of the neck and in 14 (6.14%) cases knots were found below the chin. Amongst all neck structure injuries, rupture/contusion of sternocleidomastoid and other strap muscles of the neck were found in 26.75% of cases. In 27.63% of cases, a carotid intimal tear was identified. Additionally, a hyoid bone fracture was observed in 1.75% of cases, and a thyroid cartilage fracture was present in 0.87% of cases. No injury to the cervical vertebra or cricoid cartilage was found.

Manual strangulation cases pose a unique challenge in forensic medicine due to the subtle nature of injuries, particularly concealed bruises that may go unnoticed during initial examinations. This case report aims to shed light on the often-overlooked signs of manual strangulation and the importance of meticulous forensic examination. We present a case involving a victim of manual strangulation where initial external examinations failed to reveal apparent signs of trauma. However, a detailed forensic analysis uncovered concealed bruises in unexpected locations, highlighting the elusive nature of injuries associated with manual strangulation. The victim’s delayed presentation further underscored the need for heightened clinical awareness and a multidisciplinary approach in such cases. Detailed documentation of the concealed bruises involved close collaboration between forensic experts, medical professionals, and law enforcement. Advanced imaging techniques, such as ultraviolet and infrared photography, played a crucial role in unmasking the hidden injuries. The case report discusses the challenges encountered during the investigation and emphasizes the importance of incorporating these innovative methods in forensic protocols. This case report underscores the significance of recognizing concealed bruises in manual strangulation cases, emphasizing the need for a comprehensive approach to forensic examinations. By raising awareness of the subtle signs associated with manual strangulation, this report aims to contribute to improved forensic practices and increased collaboration among experts in unraveling the silent but critical evidence that may be hidden beneath the surface.
