Black soldier fly larvae can clean up the environment by transforming low-value organic waste into high-nutrient proteins, which can be used in livestock farming, including aquaculture. The objective of the study was to assess the effect of the composition of various organic substrates on the productivity and nutritional quality of black soldier fly (BSF) larvae. Four treatments (T1, T2, T3, T4) are based on organic materials (brewer's grains, palm kernel cake, soybean okara, (Moringa oleifera) leaves, marine fish and poultry viscera) in defined proportions. The chemical analyses carried out on the substrates are: pH, moisture, total nitrogen, assimilable phosphorus, potassium, dry matter, ash and those on the BSF larvae concern: protein, fat, dry matter and ash. The experimental set-up used is a completely randomized block of 12 tanks arranged in triplicate. The loading density was 5750 larvae per kg of substrate. The experiment lasted 14 days. No significant difference was obtained between the pH values (p>0.05) of treatments T1, T3 and T4. The highest results for moisture, total nitrogen, and assimilable phosphorus were obtained in treatments T3 (marine fish viscera) and T4 (poultry viscera) (p˂0.05). Also, the best (final weight, weight gain per larva and survival rate) and nutritional qualities (proteins and lipids) were recorded in BSF produced from treatments T3 and T4 (p˂0.05). We can therefore conclude that the quality of the production substrate influences the productivity and quality of the BSF produced. Such a substrate, rich in chemical and nutritive elements, improves the productivity and quality of the BSF.

A study was conducted on Basil (Ocimum Basilicum) crop grown under Polyhouse hydroponics in different seasons by controlling the environmental parameters at Dr. NTR College of Agricultural Engineering, Bapatla. The research work conducted for four seasons i.e., Season1(April and May), Season2(August and September), Season3(October and November) and Season4(January to February) on environmental parameters is presented in this paper. The environmental parameters were tried to be controlled to maintain a proper relative humidity range, i.e., 60-75%, a temperature below 30 °C, and CO2 levels of 600 to 1500 ppm. The controlled environment and observations recorded by using Rotronic CP11’for crop analysis purpose. This makes a good quality and disease-free crop production. The final results reveal that the highest yield of 41.7 kg in seaso, followed by 40.5 kg in season2, 38.9 kg in season3, and 36.2 kg in season4. The lowest yield of all the seasons was 36.2 kg in season4. Ultimately, the experiment showed that the basil crop grows in good health throughout Season1 and then again during Season2. Polynomial equations were fitted for the humidity and temperatures maintained inside the hydroponic polyhouse which are discussed in this paper. R2 values between 0.5 and 0.7 were obtained for all the fitted equations. According to the study, yield has a positively correlated with temperature and negatively correlated with relative humidity and carbon dioxide.

Published: November 2024

Okra (Abelmoschus esculentus L. Moench) is a widely cultivated vegetable in Asia, facing ongoing challenges from aphids (Aphis gossypii Glover). A field study was conducted on a microplot in Kasilingapuram, Karungulam block, Thoothukudi district, during the Rabi season of 2020 and the Summer of 2021. Various plant growth-promoting rhizobacteria (PGPRs) were applied to the hybrid COBh 4 okra cultivars through soil, seed, and foliar treatments, and their impact on aphid populations was assessed. The findings revealed a significant reduction in aphid numbers and enhanced production of defensive compounds and enzymes in plants treated with Bacillus subtilis Bbv57 during both the seasons. These results suggest that incorporating PGPRs could be an effective strategy for managing aphid populations by boosting up the biochemical compounds in okra cultivation and can be incorporated in IPM practices.

Published: November 2024

Synthetic/chemical fertilizers has been rapidly increased due to extensive agricultural activities to meet the demand for food to sustain an ever-expanding global population which has become a pressing concern. There is a need for development of sustainable agricultural practices which promote the use of natural fertilizers to improve soil health and support high value crops for cultivation. Bat guano, an organic fertilizer composed of bat excrement, has gained attention as a promising substitute for synthetic fertilizers, offering numerous benefits to plants and soil health as it’s highly rich in nutrient contents. Fenugreek (Trigonella foenum-graecum), a versatile annual herb, with multifarious uses can be used for exploring natural fertilizers for enhancing quality and crop productivity. Hence present study was under taken to examine the impact of bat guano application on the growth and productivity of fenugreek. Amongst all the treatments, the highest germination was recorded in 50% guano with soil amendments treatment resulting in 99% germination rate followed by 100% guano (96.3%). Least germination rate was observed in control with only 85.3%. Also, 50% was best treatment with maximum plant height of about 16.3 cm within 4 weeks period compared to vermicompost (15.9cm) and control (11.3cm). Similarly, leaves number per plant was also maximum in 50% guano (10.33 leaves/plant) followed by vermicompost (10 leaves/plant). NPK content of plant and soil were also analysed using standard techniques which provides valuable insights into the existing soil composition, enabling informed decisions on how to use bat guano effectively to correct nutrient deficiencies and support optimal crop growth. Further studies are recommended to assess the benefits from the use of Bat Guano as a plant fertilizer in sustainable agriculture.

Cattle, sheep, and goats are crucial to human development, serving as major protein sources, income providers, and as a hedge against economic risk in Ghana. The demand for protein from these animals has significantly outpaced supply, partly due to insufficient or unavailable feed resources. This study investigates the use of poultry litter as a feed supplement for livestock. Data were collected from 125 livestock farmers raising cattle, sheep, and goats, using a simple random sampling technique and a structured questionnaire. Results show that cassava husk is the primary feed source, with all respondents (100%) unaware of poultry litter as a potential feed supplement. Interestingly, a majority were aware of irradiation as a decontamination method for food products. Logit regression analysis indicated that farmers’ likelihood of using irradiated poultry litter as feed is influenced by the number of animals they own. Based on these findings, it is recommended that farmers be educated on the nutritional and economic benefits of using poultry litter as a sustainable feed supplement.

Authors: Huo Feilong , Liu Yue , Zhang Andruli
Published: November 2024

Adequacy of food supply has a significant effect on the sex ratio of juvenile sea lampreys, which also adjusts to
changes in the external environment, influenced by resource availability, position in the food web, and ecological
niche. Therefore, it is necessary to pay attention to the effects of changes in sea lampreys' sex ratio on ecosystem
interactions. In this paper, we constructed an ecosystem model. We comprehensively analysed the impacts of sea
lamprey's sex ratio changes on the ecosystem from the four dimensions of the logistic equation of the population
dynamics model, the sex ratio model, the food web model, and the spatio-temporal model1,2,3. The study showed
that the sea lampreys population showed adaptability to changes in the environment4
, and its population was
affected by ecological niche and resource utilisation; incubation temperature had a significant effect on the sex
ratio; the sea lampreys played an important role in the balance between predators and prey; and showed
adaptability to the gradient of the environment, suggesting that spatial heterogeneity exists in the ecosystem. The
comprehensive assessment showed that the multilevel impacts of the sea lampreys on ecosystems included the regulation of population dynamics, the maintenance of food web balance and adaptation to changes in the environment, thus playing an important role in the stability and functioning of ecosystems.

Multidrug Resistance And Phenotypic Characterization Of Biofilm Formation By Staphylococcus Aureus: Contributions To Public Health
Authors: Tavares Agueda Maria De França , Souza Cintya Neves De , Carvalho Carolina Magalhães Caires , Sanglard Demerson Arruda , Almeida Anna Christina De
Published: November 2024

Background: In humans, the increase in bacterial resistance in samples isolated from infectious processes seems
to be caused not only by the inappropriate and intensive use of antimicrobials, but also by transmission through
food of animal origin or direct contact with farm animals. Microbial biofilms have effects on public health and
industrial considerations regarding their influence on the economy, energy use, deterioration of equipment and
the occurrence of infections. Thus, biofilm production can significantly impact disease progression and treatment
outcomes, and may favor antimicrobial resistance. Studies that evaluate the relationship between biofilm
production and antimicrobial resistance can help to elucidate mechanisms that may influence the efficacy of
antimicrobial therapy against microorganisms. This study aimed to evaluate the profile of multidrug resistance
and phenotypic characterization of biofilm formation by Staphylococcus aureus isolated from cases of infectious
bovine mastitis on dairy farms in northern Minas Gerais, Brazil. (10)
Materials and Methods: We analyzed 23 S. aureus isolates (A - Z) from subclinical mastitis, previously identified
by the MALDI-TOF MS technique. Sensitivity to antimicrobials was obtained using the disk diffusion method.
Biofilm production was determined using Congo Red Agar and the plate adherence test. Descriptive statistics
were used to distribute relative and absolute frequencies for the microbiological findings. (10)
Results: Most of the isolates were resistant to the antibiotics ASB (96%), OXA (92%) and ME1 (83%). Only
isolate B proved resistant to all the antibiotics used. Using the Congo Red Agar test, 96.66% of the samples
showed the ability to form biofilms, which were associated with resistance to the antibiotics ASB and IPM.
However, only 16.66% of the isolates were positive for biofilm formation in the plaque adhesion test. (10) Conclusion: The presence of multi-resistant, biofilm-forming bacteria represents a health risk. Rapid detection methods are essential to control these pathogens in the food industry. (10)
The Advent Of The New Procurement And Contracting Law: A Perspective On The Implementation Process Through The Lens Of Strategy As Social Practice
Authors: Halma Eduarda De Morais , Castro Marcos De
Published: November 2024

This study examines the impact of the New Public Procurement and Contracts Law (Law No. 14,133/2021) on the
strategic management of public organizations, focusing on strategy as a social practice. The research addresses
the changes brought by the new legislation and the implementation of strategies to facilitate adaptation. By
replacing Law No. 8,666/1993, the new law modernizes public procurement processes, promoting digitalization,
simplification, and greater transparency. A case study conducted in a municipality in Paraná, Brazil, revealed
how the local administration adapted its procurement processes to meet the new legal requirements. The concept
of strategy as a social practice was essential in understanding how the law was successfully implemented,
highlighting the importance of the participation of various organizational actors in strategy formulation and
execution, based on an understanding of practices, praxis, and practitioners in the strategic process.
Background: Through the lens of strategy as a social practice, this study aims to understand the process of
implementing the New Public Procurement and Contracts Law, Law No. 14,133, in the Municipality of Turvo,
located in the State of Paraná, Brazil. For 30 years, the country used specific legislation to carry out its public
procurement processes, and with the sanctioning of Law No. 14,133, public administration had to adapt to the
changes brought about by the new regulation, which altered organizational practices and routines. Considering
the change process, this study was conducted to understand the strategies created in the implementation process,
identifying practices, praxis, and practitioners through the approach of strategy as a social practice.
Materials and Methods: Using a case study and a qualitative approach, the article aims to understand the social
practices of the organization's actors to identify the strategy creation process in implementing the New Law. This
was achieved through semi-structured interviews and participant observation, analyzing routines and the social
reality experienced, thus identifying practices, praxis, and practitioners.
Results: The study identified the implementation process in the Municipality of Turvo, as well as the strategizing
process.
Conclusion: Understanding social practice within organizations is essential for identifying how strategies are
created, often without the organizational actors realizing it. This study found that strategy creation is not always initiated by executives but rather by practitioners involved in operational processes

Published: November 2024

A segmentação no mercado de trabalho é um fenômeno que reflete a divisão do mercado em subgrupos com
características, regras e remunerações distintas, resultando em desigualdades ocupacionais e salariais. Este
estudo analisa os determinantes e implicações desse fenômeno, destacando suas limitações e contribuições
teóricas, com foco nos contextos de economias desiguais. Por meio de uma revisão teórica abrangente, foram
investigadas as críticas à Teoria do Capital Humano e as principais abordagens sobre segmentação, incluindo
mercados primários e secundários, formais e informais, bem como perspectivas institucionais e históricas. Os resultados evidenciam que a segmentação é influenciada por fatores estruturais, como a organização industrial,
as relações de poder e a regulamentação, perpetuando barreiras à mobilidade ocupacional e à equidade no
mercado de trabalho. Conclui-se que, para mitigar os efeitos negativos da segmentação, é necessário
implementar políticas públicas que favoreçam a inclusão e a integração entre segmentos, além de estratégias
empresariais que promovam um ambiente laboral mais equitativo. Este estudo contribui para a compreensão da segmentação e oferece subsídios para ações que visem reduzir as desigualdades no mercado de trabalho.

Research On Failure Characteristics Of Coal Under Compression-Shear Load Based On Acoustic Emission
Authors: Xi Danyang , Xu Jiankun , Zhou Rui
Published: November 2024

In the compression-shear loading experiment of coal samples, the relationship between acoustic emission
signals and sample failure process was analyzed from the time domain characteristics, frequency spectrum
characteristics, and fracture component characteristics of acoustic emission signals. The experimental results
show that during the compression-shear failure process of coal samples, tensile fracture occurs at the inflection
point of the stress curve, while shear fracture occurs at multiple periods, with the most concentrated being the
macroscopic failure of the sample. When the coal sample approaches failure, large-scale cracks expand, so that
low-frequency acoustic emission events increase most significantly. After the coal sample is destroyed, apart from fracture along the shear plane, the areas of local peeling and large-scale collapse are mainly caused by tensile failure
Experimental Analysis Of Two Unreinforced Masonry Walls Under Cyclic Loads, And Its Retrofitting Through CFRP
Authors: Samberou Dr. Adamou Marou Seyni
Published: November 2024

This article presents a comparative experimental study of two unreinforced masonry walls: one made of
perforated bricks (285 mm x 185mm x 130 mm) and the other of threshing bricks (190 mm x 90 mm x 50 mm).
The Masonry walsl were constructed with standardized Turkish bricks in a rectangular steel frame supported
by pinned uprights and built over a distance of 1200mm in length by 1500mm in height. The main objectives of
this work are to study the behavior of structural unreinforced masonry under seismic actions and how it can be
made more resistant to these effects. To achieve this goal, lateral cyclic loads are applied to the walls in plane.
This application of forces had caused damage characterized by cracking. The natural excitation of the
unreinforced masonry walls is determined through Operational Modal Analysis (OMA), and the dynamic
characteristics of the structures emerged in the form of vibrational modes and natural frequencies. Their data
recording is made before and after the application of cyclic loading. The reinforcement to fill the cracks is
carried out using layers of CFRP with epoxy resin. A comparative analysis of the natural frequencies from
undamaged wall to damaged points out a decrease in damaged walls (more than 20%) and a rise of 10% of
frequencies between damaged vertical brick wall compared to the damaged coated CFRP-reinforced walls. These results of laboratory tests are compiled and compared in order to evaluate the seismic effects and the solutions that the CFRP brought in the reinforcement of the walls.

Authors: Deori Doli , David Dr. Venice Mairya
Published: November 2024

Background: The increasing participation of women in the workforce has heightened the challenges working
mothers face in balancing professional and parental responsibilities. Childcare arrangements significantly
influence the stress levels of these mothers, especially for those working in general and shift duty roles.
Understanding the impact of various childcare options is crucial to formulating supportive policies that
improve the well-being of working mothers.
Materials and Methods: A cross-sectional survey was conducted among 60 working mothers (30 in general
duty and 30 in shift duty) with children under 10 years in Dispur community, Guwahati. A non-probability
convenient sampling technique was employed. Data were collected using a standardized parental stress scale
and analyzed through descriptive statistics, one-way ANOVA, and Chi-square tests.
Results: The findings revealed that working mothers who relied on family members for childcare experienced
the lowest stress levels (mean score 35.4), while those using part-time nannies experienced the highest stress
levels (mean score 74.6). Significant associations were found between parental stress levels and factors such as
childcare arrangements, age, number of children, and job satisfaction.
Conclusion: The type of childcare arrangements significantly impacts the stress levels of working mothers. Policies aimed at enhancing the availability and reliability of childcare options could alleviate stress and improve the quality of life for working mothers, particularly in shift duty roles.

Published: November 2024

This research aimed to examine the influence of varying levels of cow dung-poultry droppings (COPODs) and
plant spacing on the growth and yield of different watermelon varieties. Four COPOD levels ([without
COPODs], [4t + 1t COPODs], [8t + 2t COPODs], and [12t + 3t COPODs]), four plant spacing options (25,
50, 75, and 100 cm), and four watermelon varieties (Sugar baby, Koalack, Royal sweet, and Paradise) were
combined in a factorial experiment to assess their effects on key growth metrics, including vine length, leaf
production, fruit weight, and yield. The study found that increasing levels of COPODs and wider plant spacing
significantly promoted vine length, leaf production, fruit weight, and overall yield. Among the varieties tested,
Koalack demonstrated the most vigorous growth, although differences between varieties were not always
statistically significant. While interactions between COPODs, spacing, and variety generally did not produce
significantly different outcomes, there were notable interactions between COPODs and spacing, as well as
between spacing and variety. These results highlight the importance of organic fertilization and appropriate
plant spacing in enhancing the growth and yield of watermelon varieties. The findings suggest that adopting a combination of wider planting distances and adequate applications of COPODs can be a valuable strategy for maximizing watermelon production

From an experiment with 30 lines and varieties, five oriental tobacco genotypes (four newly created lines and
one standard variety) were selected and examined for: stalk height with and without inflorescence, number of
leaves per stalk, length, width and leaf area from the middle beld of the stalk and yield of dry leaf mass per
stalk, dekar and hectare. The trial was set up in the Experimental Field of Scientific Tobacco Institute – Prilep
in 2022 and 2023, in randomized block design with four replications, using traditional agricultural practices.
Measurements of the morphological characteristics were made at the stage of butonization and beginning of
flowering. The yield of dry leaf mass was determined during the treatment of cured tobacco. The results were
statistically processed.
The aim of the research is to study the more important quantitative characteristics of the oriental genotypes, to
determine the degree of uniformity of the populations through their variability and to emphasize the best among
the selected assortment.
From the analysis of the results obtained from the comparative experiment, it can be concluded that the lines Lc and L-d are high-yielding, phenotypically and genotypically uniform and stable, thus granting a visa for their recognition as varieties by the Variety Commission from the Ministry of Agriculture, Forestry and Water management of the Republic of North Macedonia

A pesquisa teve como objetivo analisar o papel das políticas públicas na integração da educação antirracista no
currículo escolar brasileiro, considerando a complexidade das percepções e práticas dos educadores. Realizada com uma abordagem qualitativa e exploratória, a amostra foi composta por quinze professores de uma escola selecionados por conveniência, e os dados foram coletados por meio de entrevistas em profundidade, analisadas
através da técnica da análise do discurso. Os resultados revelaram uma dualidade nas experiências dos
educadores, com resistência à abordagem de temas raciais, mas também um significativo interesse por parte dos
alunos em aprender sobre a cultura afro-brasileira. Essa dinâmica aponta para a necessidade urgente de
formação contínua dos professores, que se mostraram inseguros em lidar com questões delicadas de identidade
racial. A conclusão enfatiza que, para a efetivação da educação antirracista, é imperativo que as políticas públicas não apenas ofereçam diretrizes, mas também promovam programas de formação e um comprometimento coletivo entre escolas, famílias e comunidades, visando a construção de uma sociedade mais justa e igualitária

Esta pesquisa teve como objetivo investigar a relação entre a qualidade de vida no trabalho e a eficiência dos
serviços de saúde, explorando como as condições de trabalho impactam o bem-estar dos profissionais e,
consequentemente, a qualidade do atendimento aos pacientes. A pesquisa foi de caráter exploratório e qualitativo,
com uma amostra de vinte profissionais de saúde selecionados por conveniência. A coleta de dados foi realizada
por meio de entrevistas em profundidade, analisadas com a técnica da análise do discurso. Os resultados
revelaram que fatores como sobrecarga de trabalho, falta de recursos, ausência de apoio emocional e dificuldade
de equilibrar a vida pessoal e profissional são determinantes para a baixa qualidade de vida no trabalho, o que,
por sua vez, compromete a eficiência no atendimento. No entanto, aspectos como valorização profissional,
trabalho em equipe e a implementação de programas de apoio psicológico e capacitação mostraram-se
estratégias positivas para melhorar o bem-estar dos profissionais e a qualidade do serviço prestado. A pesquisa
conclui que investir na qualidade de vida no trabalho não só melhora o bem-estar dos trabalhadores da saúde, mas também é fundamental para a eficiência dos serviços de saúde, sendo essencial para garantir um atendimento mais humanizado e eficaz aos pacientes

Esta pesquisa teve como objetivo investigar o impacto do estresse e do burnout entre os profissionais da saúde
em uma instituição pública, buscando identificar os fatores que contribuem para esses quadros e suas
consequências tanto para os trabalhadores quanto para a qualidade do atendimento aos pacientes. Trata-se de
uma pesquisa exploratória com abordagem qualitativa, realizada por meio de entrevistas em profundidade com
vinte profissionais de diferentes áreas da saúde. Os resultados indicaram que a sobrecarga de trabalho, a falta
de reconhecimento, a constante exposição ao sofrimento e à morte, a ausência de suporte institucional e a
dificuldade na gestão do tempo são os principais fatores de estresse e burnout. Esses fatores, aliados à falta de
estratégias eficazes de enfrentamento e ao isolamento emocional, impactam diretamente a saúde mental dos
trabalhadores e a qualidade do cuidado oferecido aos pacientes. Conclui-se que a adoção de políticas de apoio
psicológico contínuo, a valorização profissional e a reorganização das tarefas no ambiente de trabalho são essenciais para reduzir o estresse e prevenir o burnout, promovendo, assim, um ambiente de trabalho mais saudável e eficaz, o que, por sua vez, resultará em melhor atendimento à população.

Esta pesquisa teve como objetivo investigar a aplicação da inteligência artificial (IA) e do big data na gestão escolar, explorando as percepções e experiências de 23 professores sobre essas tecnologias. Utilizando uma abordagem exploratória de natureza qualitativa, foram realizadas entrevistas semi estruturadas que foram analisadas por meio da técnica de análise de conteúdo. Os resultados revelaram que, embora os educadores reconheçam os benefícios da IA e do big data, como a personalização do ensino e a análise eficiente de dados,
também emergem desafios, incluindo a necessidade de formação contínua, infraestrutura tecnológica adequada
e a resistência a mudanças. A análise destacou a importância de políticas que garantam a privacidade dos dados
dos alunos. Conclui-se que, para a implementação dessas tecnologias na educação, é essencial que gestores e formuladores de políticas abordem de maneira integrada esses desafios, promovendo um ambiente educacional que utilize a tecnologia de forma ética e inovadora, a fim de potencializar a aprendizagem e a eficiência na gestão escolar
