Objetivo: Investigar se o comprometimento do estado funcional e os sintomas da COVID-19 persistem após seis meses em pacientes previamente internados. Métodos: Estudo observacional analítico com abordagem qualitativa, conduzido em duas etapas e por meio de ligações telefônicas. Na primeira etapa, realizou-se abordagem inicial e convite aos participantes 30 dias após a alta hospitalar. A segunda etapa, seis meses após esse primeiro contato foi realizado a avaliação da Medida de Independência Funcional (MIF). Resultados: Dos 110 pacientes inicialmente internados,103 concordaram em participar do estudo. Eram predominantemente homens, com média de 45 anos. Após seis meses, 64 participantes foram localizados e realizaram a avaliação da MIF. Os resultados indicam que os domínios da MIF, mobilidade e transferências, locomoção, e, notadamente, o domínio cognitivo social, especialmente a categoria memória, foram os que apresentaram comprometimento. Contudo, a porcentagem de necessidade de auxílio nessas tarefas foi baixa. Conclusão: Seis meses após COVID-19, o estado funcional dos sobreviventes não apresentou comprometimento significativo, mas persistiram alguns sintomas após a internação e portanto é evidente a necessidade dos serviços de saúde de se readequar e criar estratégias para proporcionar a recuperação físico-funcional e reintegração social completa desses indivíduos.

The aim of the work is to develop a modern, machine-oriented and scalable technique for describing the processes of quasi-static bending of rod elastic elements with concentrated masses. Currently, in various branches of mechanical engineering, the problem of developing and modifying various shock-absorbing devices operating on the principle of resistance to bending of rod elastic elements is relevant. This paper presents a method for solving problems of calculating the quasi-statics of rod elastic elements containing fixed concentrated masses, based on the Euler-Bernoulli bending model, a modified bending moment equation and initial conditions for solving the Cauchy problem. The presented system of equations for optimizing labor intensity is proposed to be solved using a machine-oriented "evolutionary" method of minimizing the objective function. Numerical solution of the given system of equations, including the problem of minimizing the objective function with several arguments, is carried out using the Python programming language and the SciPy library. The results of calculations of the position and force characteristics for rods with different parameters of concentrated masses loaded according to a non-slip tracking loading scheme are demonstrated. As a result, the possibility of controlling the force characteristics of rod elastic elements by using fixed concentrated masses is shown.

Published: September 2024

Agricultural mechanization is pivotal in farmer’s fields as it functions more efficiently and helps increase farm productivity. Despite the massive involvement of people in agriculture, farm productivity is relatively low. One main reason for this is the staggered implementation of farm mechanization. This paper aims to explore the factors affecting the adoption of farm mechanization using the Chi-square test and identify the major problems using relative frequency values. A total of 112 respondents, 28 each from 4 municipalities of Rupandehi district were interviewed based on stratified random sampling technique. The results showed that the adoption rates of various farm machinery were notably high, with tractors, cultivators, mills, and sprayers being universally employed by 93.75 % of the surveyed individuals. The government subsidies to only 7% of farmers facilitate machinery procurement. The size of the total cultivated land was found to be significant over the use of harvester, grass cutter, and power tiller, and owing of milling machine. The availability of subsidies and owning of mills were found inter dependent. The annual expenditures of farmers and their access to theCusto m Hiring Centre were found to be significant. Lastly, with index values of 0.402 and 0.393, the high costs of farm machinery and small land holdings were major problems in the adoption of farm mechanization. Therefore, addressing the high initial costs of modern farm equipment, providing targeted subsidies, innovative institution formation to provide better services to marginalized farmers, and expanding extension services are essential steps to promote the adoption of farm mechanization.

Indonesian black rice is quite popular for its highly nutritive value and profitable production. The distinct knowledge about optimum fertilizer doses and plant spacing contributes to its promising yield. The experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh, from December 2022 to May 2023 to find out the effect of fertilizer management and plant spacing on the growth and yield of Indonesian black rice in the winter season. The experiment was conducted with 5 treatments of fertilizer management viz., F1(70% of recommended doses); F2(80% of recommended doses); F3(90% of recommended doses); F4(100% of recommended doses) and F5(110% of recommended doses) with 4 plants spacing viz., S1(20 cm × 15 cm); S2(20 cm × 20 cm); S3(25 cm × 15 cm) and S4(25 cm × 20 cm). The experiment was laid out in a split-plot design where the fertilizer management was allocated in main plots and the plant spacing was distributed in sub-plots with three replications. The result revealed that the fertilizer doses and plant spacings along with the interaction effects significantly influenced the growth and yield parameters of Indonesian black rice. Regarding vegetative growth, plant height (79.3cm), total tiller plant-1(21.27cm), and total leaf number plant-1 (58.47) were maximal at 100% recommended dose of fertilizer(F4) at DAT 65. Similarly, S2(20 cm × 20 cm) had better result in crop growth and yield attributes. The interaction effects of the treatments showed significant impact on plant height, total tiller and leaf number where F4S2 gave satisfied results. The highest values for the yield parameters including the maximum number of grains panicle-1 (100.70), 1000-grain weight (28.33g), and grain yield (5.69g) were found from the combination treatment of F4S2. On the other hand, the lowest grain (3.68g) yield was found from F1S4. Therefore, observing the results of the experiment, the best consideration was F4S2 at Agro-ecological Zone-9 in the winter season for the desirable growth and yield of Indonesian black rice.

Apple is one of the most popular fruit crops globally, including Ethiopia. However, its productivity is adversely influenced by many constraints. Insect pests, such as woolly apple aphids, codling moths, and mealybugs, are major damaging biotic constraints globally, including Ethiopia, and their population dynamics are significantly influenced by biophysical and temporal changes. Field surveys were conducted in the Chencha highlands of southern Ethiopia during the 2021 and 2022 main rainy and off seasons to determine the prevalence and incidence of these insect pests and the associations of biophysical and temporal factors with these pests’ population changes. Multistage random sampling approaches were followed for data collection, and consequently, 164 apple fields were inspected for insects’ occurrence. Logistic regression analyses were employed to determine the association of independent variables with the incidence of each insect pest. Results showed that the prevalence (90.18, 75.61, and 50.45% in 2021 and 70.26, 54.15 and 36.48% in 2022, respectively), incidence, and number of individual insects per tree varied across years, seasons, and other biophysical factors. These parameters were higher in the off-season in 2021 than in the main rainy season in 2022. Accordingly, incidences of aphids, codling moths, and mealybugs were recorded at about 57.56, 54.93, and 33.29% in 2021, and 37.01, 40.78%, and 21.23% in 2022, respectively. Association analyses revealed that independent variables such as years, seasons, altitude, age of tree, growth stages, cropping systems, weed infestation, and tree management were significantly (P<0.001) associated with the incidences of all studied insects in the reduced multiple regression model. Apple cultivation at an altitude of ≤2500 m and main rainy season with recently planted trees (≤5 years), flowering to fruit development growth stages, high weed infestation, and tree management through composting and pruning had significant associations with low wooly aphids (≤15%), codling moths (≤40%), and mealybug (≤20%) incidence and can be considered as management options to reduce the aforementioned insects and associated yield losses to ensure apple production.

The experiment was carried out to evaluate the effects of feeding frequency on the growth, production, and economic aspects of Oreochromine cichlids (Oreochromis mossambicus) in nine earthen ponds for 120 days. Three different feeding regimes (T1, T2, and T3) with three replications each were used. The stocking density was uniform across all treatments at 25,000 fish per hectare. The fish were fed a commercially available pelleted feed with the same feeding rate in all treatments, but the feeding frequency varied. The feeding rate was 10%, 8%, 7%, 6 %, 5%, and 4% which was consecutively adjusted after each fortnightly sampling and 3% for the last 4 weeks of the study period. Feeding frequencies were once a day for T1, twice a day for T2, and three times a day for T3. The average weight gain of Oreochromine cichlids in T3 (295±5 gm) was significantly higher (P<0.05) than those of T2 (240.67±6.66 gm) and T1 (217.17±7.64 gm). The survival rates were 95.20%, 96.99%, and 97.33% for T1, T2, and T3, respectively. The net production of fish in T3 (2882.00±62.00 kg/ha) was significantly higher (P<0.05) than in T2 (2413.00± kg/ha) and T1 (2223±30.55). Furthermore, the highest net return (USD 1163/ha with a cost-benefit ratio of 1.42) was achieved from T3, followed by T2 (USD 527/ha with a cost-benefit ratio of 1.19) and T1 (USD 270/ha with a cost-benefit ratio of 1.09). The results demonstrated that increasing the feeding frequency has positive effects on the growth and production of Oreochromine cichlids.
A review on tillage system and no-till agriculture and its impact on soil health
Authors: Thapa Bronika , Dura Roji 
Published: September 2024

Soil tillage is a fundamental agriculture practice aimed at preparing the soil for planting, managing crop residues, controlling weeds, preparing the ground for the next crop, integrating leftover crops and nutrients into the soil, and enhancing soil structure. However, tillage practice significantly influences activities like soil moisture, temperature, aeration, and mixing the crop residues within the soil. This article explores the impacts of traditional tillage methods and alternative approaches to reduce production costs, environmental consequences, and safeguard soil for sustainable crop production through the secondary source of results as published research papers, documents, government official and institution reports. Traditional tillage method involves the mechanical disruption of soil, which affects critical factors such as moisture retention, temperature regulation, and aeration. While use of such heavy machines can improve short-term productivity, its long-term impacts include soil compaction, erosion, and loss of organic matter, leading to environmental degradation and declining soil health. In contrast, No-till and reduced tillage practices offers a promising solution to contemporary challenges such as global climate change, water conservation, rapid soil degradation, and desertification. Under this system, wide range of crops can be grown effectively in low production cost by reducing fuel and labor requirements. No-tillage and minimal tillage is being adopted across a wide range of farm sizes, from small plots of land to vast expanses, in various countries around the world with promising sustainability.

Nitrogen fertilization and weed management is the major concern to yield maximization of rice. The study was conducted to assess the influence of nitrogen and weed control to yield improvement of aromatic rice BRRI dhan34. The experiment included three nitrogen levels viz. 50, 100 and 150 kg N ha-1 as well as three weeding schedules viz. one hand weeding at 15 days after transplanting (DAT), two hand weeding at 15 and 30 DAT and three hand weeding at 15, 30 and 45 DAT. The experiment was conducted with randomized complete block design. The findings demonstrated important correlations between weeding techniques, nitrogen levels and yield components. When the crop was fertilized with 50 kg N ha-1 the highest numbers of total tillers hill-1 (8.53), effective tillers hill-1 (7.51), grains panicle-1 (128.0) and grain yield (3.97 t ha-1) were resulted. Regarding weeding practices, two manual weeding carried out at 15 and 30 DAT reported the highest numbers of effective tillers hill-1 (7.62), grains panicle-1 (128.1) and grain yield (4.10 t ha-1). The highest effective tillers hill-1 (8.33), the most grains panicle-1 (129.8), the grain yield (4.36 t ha-1) and straw yield (6.40 t ha-1) were found in two hand weeding at 15 and 30 DAT combined with 50 kg N ha-1 and the lowest grain yield (3.53 t ha-1) was obtained from one hand weeding given at 15 DAT along with 150 kg N ha-1. Therefore, the study demonstrated that BRRI dhan34 can be fertilized with 50 kg N ha-1 along with two hand weeding at 15 and 30 DAT to obtained higher yield.
