Presence of Soybean Vein Necrosis Orthotospovirus (Tospoviridae: Orthotospovirus) in Pakistan, Pakistani Scientists’ and Farmers’ Perception of Disease Dynamics and Management, and Policy Recommendations to Improve Soybean Production
Authors: Hameed Asifa , Rosa Cristina , Castillanos Paige , Rajotte Edwin G.
Published: February 2025

Soybean vein necrosis orthotospovirus (SVNV: Tospoviridae: Orthotospovirus) is a well-recognized thrips-vectored and seed-borne virus common in the United States (U.S.), Canada, and Egypt. Pakistan started the commercial cultivation of soybeans in the 1970s, when some soybean cultivars were imported from the U.S. to meet the country’s domestic requirement of oil, poultry, animal feed, and forage. A survey of farmers and scientists was conducted in the Punjab and Khyber Pakhtunkhwa provinces of Pakistan to understand perceptions of SVNV in the indigenous Pakistani community. Concurrently, soybean fields were sampled for SVNV presence at the National Agricultural Research Institute in Islamabad, Pakistan. Based upon survey and SVNV detection results through ELISA and qRT-PCR, a policy was developed. Overall, we found that SVNV was present in Islamabad, Pakistan in USDA-approved soybean cultivars. Although scientists knew about general thrips biology and insecticides, knowledge about identification of vectors (Thrips species) was not significantly different between the scientists and the farmers. Scientists at the Islamabad location were more aware of crop production technology and pests. This study reports that Pakistan needs to strengthen its research institutes, scientists’ and farmers’ capacity building, and extension programs to understand the disease complex in soybean crops.
Derivados da vitamina E complicações microvasculares no diabetes mellitus: uma revisão da literatura
Authors: Sena Maria Luiza Figueredo de Albuquerque Oliveira de , Nunes Alessandro de Sousa
Published: February 2025

O diabetes mellitus é uma condição metabólica associada a altas taxas de complicações microvasculares e dislipidemia, frequentemente mediadas por estresse oxidativo e inflamação. Considerando a necessidade de terapias que reduzam esses riscos, este trabalho objetiva revisar a literatura sobre o impacto dos derivados da vitamina E, especialmente tocotrienóis, na prevenção da progressão dessas complicações em pacientes diabéticos. Para tanto, foi realizada uma revisão narrativa com base em estudos experimentais e clínicos disponíveis nas bases de dados científicas. Observa-se que, enquanto modelos experimentais sugerem efeitos antioxidantes e anti-inflamatórios promissores dos tocotrienóis, grandes estudos populacionais não demonstraram benefícios consistentes da suplementação de vitamina E para complicações microvasculares ou dislipidemia em humanos. Desse modo, conclui-se que, apesar dos potenciais efeitos biológicos identificados em estudos laboratoriais, a evidência clínica atual não suporta o uso rotineiro de derivados da vitamina E como estratégia terapêutica para pacientes diabéticos. Mais estudos são necessários para elucidar os mecanismos envolvidos e definir subgrupos que possam se beneficiar.

Published: February 2025

In article the experience of differentiation of the modes of irrigation of culture of soy in conditions of the Saratov region is considered. Researches of the modes of irrigation are executed on experimental sites of Pilot production facility «VolzhNIIGiM». During vegetation of culture the hydrothermal coefficient was equal to 0.56. The period of vegetation was moderately warm with an insufficient amount of precipitation at the beginning of the period of vegetation and adverse for shoots. Receiving a harvest requires irrigation. The irrigating norm was 1250 m3 per hectare. Vegetative waterings carried out to the following phenological phases of soy: branching, blossoming, formation of beans and maturing of grain. It is noted that in a moderately dry year, it is necessary to create a moisture supply of the culture within 1300...2700 m3 per ha. It was established that the optimal conditions for the formation of soybean yield occur under an intensive irrigation regime in the "regrowth-branching" phase (soil moisture level – 80 % of the lowest moisture capacity) and a moderate irrigation regime in subsequent phenological phases during the formation of beans (70 % of the lowest moisture capacity). According to the authors' calculations, this provides savings in irrigation water up to 15%.

The purpose of the study is to identify current effective trends in the use of plant protection products in irrigated agriculture to obtain guaranteed crop yields. The collected information base on scientific bibliographic sources with a retrospective of 46 years is considered. The classification of a complex of plant protection methods is given. Plant quarantine, biological, agrotechnical, chemical and other methods are considered. A brief overview of the main cereal pests is provided. It is noted that the modern integrated plant protection system should be built on mandatory phytosanitary monitoring and forecasting. A list of some pathogens and pests of vegetable crops and potatoes, as well as fruit and stone crops, vineyards is given. There is a close relationship between the use of pesticides and the level of crop yield. The use of protective preparations allows to obtain a high economic effect. For example, the yield of grain crops decreases by more than 40 % with a decrease of 30 % in the volume of protective measures. Taking measures to protect plants allows you to preserve more than 15% of the harvest of grain, vegetable crops and potatoes, about 25 % – sugar beets and fruits, 10 % – sunflower. The introduction of an integrated plant protection system provides an increase in grain yield by 0.95...2.95 tons per hectare, potatoes – 4...9 tons per hectare, vegetables – 5...6 tons per hectare, fruit plantations – 1...1.2 tons per hectare. The profitability of protective measures ranges from 120 to 450 %.

Study of the stacked Cu–Ga/In precursor for Cu(In,Ga)S2 solar cells
Authors: Suzuki Yota , Kobayashi Hiromu , Nishimura Takahito , Yamada Akira
Published: February 2025

Wide-bandgap chalcopyrite Cu(In,Ga)S2 (CIGS) solar cell is a promising material because its bandgap is suitable for a top-cell of a tandem solar cell. Highly efficient CIGS solar cells are typically fabricated through the sulfurization of Cu–Ga–In metal precursors. In this study, stacked Cu–Ga/In metal-precursors were prepared with varying the [Ga]/([Ga] + [Cu]) (GGC) ratio ranging from 0 to 0.55. These precursors were analyzed using X-ray diffraction based on the Cu–Ga and Cu–Ga–In phase diagrams. The results confirmed that crystal structures of the metal precursors aligned with predictions from the phase diagrams. Subsequently, CIGS absorbers were fabricated using the stacked Cu–Ga/In precursors through the sulfurization with a sulfur powder source without KCN etching, and their characteristics were thoroughly evaluated. Ultimately, a CIGS solar cell with a conversion efficiency of 10.0% was achieved at a GGC ratio of 0.30 and a CGI ratio of 0.90.
Degradation of perovskite solar cells due to pinholes transforming into current leakage points
Authors: kawamura tatsuro , horiuchi tamotsu , Ishikawa Yasuaki
Published: February 2025

We have demonstrated the degradation of perovskite solar cells (PSCs) due to the transformation of pinholes into current leakage points. We intentionally formed pinholes in the perovskite (PVK) layer using laser processing techniques to evaluate the impact of the pinholes on the performances of the PSCs and to observe the behavior of the pinholes. The initial performance of the perovskite solar cell (PSC) with formed pinholes indicates that all formed pinholes did not work as current leakage points immediately after the fabrication. However, 2 weeks of storage in a dark desiccator at room temperature and 3 minutes of activation by the Air Mass 1.5 Global (AM 1.5G) irradiation caused some formed pinholes to transform into current leakage points. As a result of this transformation, the performance of the PSC with formed pinholes degraded. The transformation of pinholes into current leakage points was shown to be one of the degradation factors.

Published: February 2025

A special category of basal plane dislocations which have been found at interfaces in 4H-SiC epitaxial wafers have attracted more and more attention in recent years. These interfacial dislocations could locate either at the bottom of an implanted layer or at the epilayer/substrate interface. While the latter type has been studied extensively in literature, formation mechanism of the implantation-induced interfacial dislocations remains unclear. In this paper, the critical role of thermal stress in interfacial dislocation formation during activation annealing is determined by annealing the ion-implanted 4H-SiC epitaxial wafer with a large temperature gradient. Microstructures of the interfacial dislocations are analyzed based on the configuration of partial dislocations that they dissociate into.

Published: February 2025

Autism Spectrum Disorder (ASD) is a complex neurodevelopmental disorder characterized by difficulties in social interaction, communication, and repetitive behavioral patterns. Early detection of ASD is crucial for improving the quality of life of affected individuals and alleviating the burden on their families. This study proposes a computer-aided diagnostic system for ASD by applying a pre-trained Vision Transformer (ViT-B/16) architecture to EEG signal data obtained from King Abdul Aziz University. The dataset comprises EEG recordings from 16 subjects (8 normal and 8 ASD) that have undergone preprocessing—including filtering using the Discrete Wavelet Transform (DWT), segmentation (windowing), and conversion into heatmap representations—and were subsequently partitioned into training, validation, and testing subsets. The ViT model was trained for 100 epochs with a batch size of 16, using the AdamW optimizer and the CrossEntropy loss function, while two learning rate configurations (0.0001 and 0.00001) were evaluated; the best-performing weights were selected based on the lowest validation loss. Test results indicate that the model trained with a learning rate of 0.00001 achieved a testing accuracy of 99.53%, accompanied by excellent precision, specificity, recall, and f1-score, thereby demonstrating strong generalization capabilities and minimal overfitting. Future research is recommended to incorporate locally sourced datasets and to further customize the ViT architecture through comprehensive hyperparameter tuning, with the aim of developing a mobile application to support clinical ASD diagnosis.

This research was conducted to evaluate the effect of the combination of Leucaena and Indigofera in swamp grass-based rations on the quality or quantity of feed produced. The research was carried out based on a completely randomized design (CRD) consisting of four treatments and four replications. The types of forage used include termite Bento grass (Leersia hexandra) from swamp land; legumes Leucaena and Indigofera. The treatments consisted of A = swamp grass and concentrate (70%:30%), B = swamp grass, Leucaena and concentrate (40%:30%:30%), C = swamp grass, Indigofera and concentrate (40%:30%:30%), D = swamp grass, Leucaena, Indigofera and concentrate (40%:15%:15%:30%). The observed variables consisted of dry matter digestibility (DMD), pH, total Volatile Fatty Acid (TVFA), N-ammonia (N-NH3), partial VFA, methane gas, total bacteria and protozoa. The study showed that the combination of tree legumes increased (P<0.05) the digestibility values of DM, TVFA, propionic acid, butyrate and total bacteria, while the levels of N-NH3, acetic acid, acetate-propionate ratio, methane gas, methane gas production and protozoa decreased (P<0.05). Based on the results of the study, it can be concluded that the combination of tree legumes in the ration can increase digestibility, improve rumen fermentation characteristics and reduce methane gas production.

Published: February 2025

Hand fractures are extremely common and many of these fractures may be treated effectively by non-surgical methods.
Surgical fixation is the choice of management for unstable, displaced fractures and it requires a good understanding of
the fracture morphology, surgical skill and implant preference of the surgeon. K-wires as an implant can provide a
minimally invasive, cost-effective, stable fixation of the fracture and combined with early mobilization, enables the
patient to get favorable functional outcomes. A common method of fixation is using 2 crossed K wires which although can
provide a more rigid fixation, is not without challenges. We describe with a case of a middle phalanx fracture of the nondominant hand in a manual labourer, who underwent fracture fixation with a single Kirschner wire and was instituted
early active mobilization. By the post-operative 6th week, he achieved an excellent functional outcome.

The basal metabolic rate (BMR) is the amount of energy needed while resting in a temperate environment when the
digestive system is inactive.Heat (energy) is the most essential thing for living beings.In Unani system of medicine this
energy is defined as a Hararat-e- Ghariziyah (Innate heat) which is considered essential for Life. It is assumed that all
body functions are maintained by different Capacities/Faculties of the body and these capacities are dependent on
Innate heat. Heat in the body is one of the most important component because for every work heat is the basic
requirement. One of the concepts of arrat Gharziyya (innate heat) is there which describes that for a cell to
complete its life Rabat Gharziyya and arrat Gharziyya is necessary.Production of heat in the body is one of the
most important and very necessary tasks because for every work heat is the basic requirement Any deviation in this heat
from its normalcy and moderation,the body functions get disturbed and extreme deviation of Innate heat from normalcy

Effectiveness of Conjunctival Flap Surgery in Managing Non-Healing Corneal Ulcers
Authors: Alam Dr. Md. Kibria , Matin Dr. Md. Abdul
Published: February 2025

Background: Non-healing corneal ulcers pose a significant challenge in ophthalmology, often resulting in persistent pain, visual impairment, and corneal perforation. Conventional medical treatments may fail to promote healing in refractory cases, necessitating surgical intervention. Conjunctival flap surgery provides a vascularized and protective layer that facilitates corneal healing and structural preservation. Objective: This study aims to evaluate the effectiveness of conjunctival flap surgery in managing non-healing corneal ulcers by assessing its impact on corneal healing, symptom relief, and overall visual prognosis. Methods: A retrospective study was conducted at a tertiary eye hospital in Bangladesh, including 47 patients who underwent conjunctival flap surgery for non-healing corneal ulcers between April 2020 and January 2022. Patients were assessed preoperatively and postoperatively using visual acuity testing, slit-lamp examination, fluorescein staining, and anterior segment optical coherence tomography. Data were analyzed using SPSS version 25. Results: The study population consisted of 63.82% males and 36.17% females, with the majority (57.4%) aged between 41 and 60 years. Infectious etiology was the most common cause of corneal ulcers (65.96%). Postoperatively, best-corrected visual acuity (BCVA) improved in 31.91% of patients, decreased in 46.81%, and remained unchanged in 21.28%. Anatomic cure was achieved in 72.34% of cases, with only 3 eyes requiring evisceration. Postoperative complications included flap necrosis (14.89%), flap displacement (8.51%), anterior corneal staphyloma (2.13%), and corneal perforation (2.13%), while 72.34% experienced no complications. Conclusion: Conjunctival flap surgery is an effective treatment for refractory corneal ulcers, preserving ocular integrity and facilitating corneal healing. While visual acuity may not always improve, the procedure remains a crucial alternative to emergency penetrating keratoplasty, particularly in regions with limited access to corneal tissue.

For complex systems, which include modern hydraulic drives, it is very important to develop technologies for controlling the condition of the working elements of hydraulic drives and for detecting faults in hydraulic system units in order to improve the operability of hydraulic drives. In this article, the technology for testing hydraulic drives of attachments by checkpoints is presented. A refined calibration of hydraulic drives depending on the load increase in 1 kg increments is proposed. The fixation of changes in the monitor indications of the developed device is presented, the application of which makes it possible to present the necessary amount of information about diagnostic parameters for the preparation of a conclusion about the changes in the device indications. The indications were decoded using the Microsoft Excel application. The average values of the device indications at different impact forces on the strain gauges of the device, standard deviations and coefficients of variation were determined. The test results are presented in the form of graphs of the dependence of the average device indication and the standard deviation on the pressure in the pipeline. At the final stage of the tests of the developed device, the fixation of the pressure in the pipeline during the transient process that occurs during the period of operation of the automatic valve of the piston valve of the hydraulic distributor was checked. The methods and means used should ensure a low error in diagnosis with a reduction in the duration of operations to measure the quantitative values of technical condition parameters with subsequent processing and analysis of the results.

The sanitary and hygienic properties of milk were determined by the following indicators: total bacterial contamination, thousand CFU / cm3, the presence of inhibitory substances, the number of somatic cells, thousand / cm3. According to organoleptic and physico-chemical parameters, the quality of cheeses was studied (the mass fraction of fat in CB, in %; moisture in %; milk consumption per 1 kg of cheese). The highest milk yield was from the mother of the mother of bulls of Leningrad selection (14,836 kg). The highest content of fat (4.36%) and protein (3.5%) in domestic selection animals was in the mothers of bulls in the Moscow selection. Among the stud bulls of imported selection, the mothers of German–bred bulls prevailed in terms of fat and protein content - 4.36 and 3.50%. When comparing the parent index of domestic and imported selection stud bulls for all analyzed characteristics, the RBI is higher in imported selection bulls. According to the level of realization of the genetic potential for milk yield in imported selection, the daughters of Dutch–bred bulls are distinguished - 48.7%. According to research, the most suitable milk for cheese production was obtained from the daughters of stud bulls of imported and Udmurt selection.

This article presents the results of the investigation of the effects of foliar fertilization on the nitrogen, phosphorus and potassium content of pea grains at different levels of mineral nutrition. The correlation relationships between the weight of 1000 grains and the content of the main macronutrients, expressed in relative and absolute values, are examined. The purpose of the study is to determine the optimal combination of simultaneous application of root and foliar nutrition, which provides a high content of the main macronutrients in the grain as an indicator of the best conditions for plant growth and development. As a result, it was found that it is permissible to focus on the indicator of the absolute content of the main macronutrients in the pea grain when evaluating the conditions for plant growth and development. This indicator shows a strong correlation with grain weight. It can be seen that the highest weight of 1000 grains is formed at all mineral nutrient levels when the plants are treated with Biostim Universal at a rate of 2.0 l/ha during the stemming and budding stages. The grains formed in these variants of foliar fertilization had the highest levels of nitrogen, phosphorus and potassium, depending on the level of mineral nutrition.

This article presents the design and technological rationale and structure of the attached telescopic lift developed specifically for use with tractors in the conditions of small economic units of the agro-industrial complex. The basic idea of the work is to create an attachment with certain load capacity characteristics.

The article emphasizes the main loads acting on the frame of a lifting equipment. The deformations and stresses in the frame were analyzed. The results of this analysis have shown that the designed and modeled frame has sufficient strength and stiffness to ensure the reliability of the lift.

Thus, the use of this mounted telescopic lift ensures safe and reliable work in areas where agricultural loads are moved.

Due to its efficiency and reliability, this equipment can be used in various industries to facilitate and automate the handling of goods, but also in small and medium-sized enterprises in rural areas. The wide use of the telescopic lifting attachment will allow it to be integrated into the zonal cultivation technologies of agricultural producers, which in turn will lead to higher productivity and lower labor costs in crop production.

This device was specially developed on behalf of the scientific and educational production center "Integration" to support various activities of the university in the field of agriculture. It will be used in the areas of production, education and practice, research and innovation related to crop production, animal husbandry, processing, storage and utilization of products, mechanization of agriculture, training and retraining of personnel, improving the quality of soil resources, increasing the economic efficiency of agricultural production, and for the approval and transfer of innovative technologies. In addition, this equipnet can also be used as an auxiliary unit to support the operation of a combined strip-seeding system for sowing crops. The number of state registration of research, design and technological development of civil use of this unit is №124012500452-2.

A apendicite aguda necrotizante é uma forma rara e grave de apendicite, caracterizada pela necrose do apêndice vermiforme e frequentemente associada a complicações graves, como sepse e peritonite difusa. A manifestação clínica pode incluir sinais de irritação peritoneal, com sintomas mais graves como distensão abdominal, febre e taquicardia. O diagnóstico é frequentemente confirmado por meio de exames de imagem, como a tomografia computadorizada, que pode identificar sinais de inflamação, empilhamento ou pneumatoseintestinal. O tratamento consiste em uma abordagem cirúrgica imediata. Este relato de caso evidencia a importância do diagnóstico precoce e da intervenção cirúrgica urgente para a redução das taxas de mortalidade e a melhora do prognóstico dos pacientes.

Os distúrbios do sono desempenham papel fundamental no desenvolvimento e progressão de diversos transtornos psiquiátricos, incluindo depressão, ansiedade, transtorno bipolar, esquizofrenia e transtornos do neurodesenvolvimento. Esta revisão narrativa explora a complexa relação bidirecional entre o sono e a saúde mental, destacando fatores genéticos, neurobiológicos e ambientais que mediam essa associação. Evidências indicam que disfunções nos genes circadianos, alterações na microbiota intestinal e problemas de sono na infância são preditores robustos para o desenvolvimento de transtornos psiquiátricos. Além disso, distúrbios do sono estão fortemente ligados a sintomas psicóticos e comportamentos suicidas. Intervenções que visam à melhora da qualidade do sono podem ter efeitos terapêuticos e preventivos significativos, reforçando a necessidade de abordagens clínicas integradas.
The role of educational social networks in teaching information technology during a pandemic: A case study
Authors: Bulatovic Jelisavka
Published: February 2025

The implementation of distance learning requires considerable technical support and reorganization of the entire education model, therefore in the Republic of Serbia, primarily in higher education institutions, a hybrid model of education is used, while a smaller number of higher education institutes are accredited for distance learning. However, the declaration of a state of emergency by the Government of the Republic of Serbia on March 15, 2020, along with the decision to temporarily close all educational institutions due to the epidemiological situation caused by the COVID-19 virus, represented a major challenge for the education system in the country itself.The preparation of most higher education institutions for the transition to online teaching ran parallel to the implementation itself, while the problems that inevitably arose were solved "on the fly", so that the teaching process would not be interrupted, but also in order to maintain the quality of teaching in took place under the given conditions. That is why the goal of this research was to determine the role of educational social networks in teaching in the field of information technology, at the Department of Management, Design and Textile Engineering - Academy of Technical - Art Professional Studies in Belgrade. The research results point to the conclusion that the effects of online teaching are mostly positive, but that it is necessary to work on further improvement, as well as more up-to-date elimination of shortcomings
Biblioteki i zrównoważenie środowiskowe – przegląd instrumentów ewaluacyjnych
Authors: Fedorowicz-Kruszewska Małgorzata
Published: February 2025

Teza/cel artykułu – Celem artykułu jest opis dostępnych w literatu- rze naukowej i fachowej narzędzi do oceny działań bibliotek w aspekcie środo- wiskowym oraz porównanie ich w zakresie obszarów poddawanych ewaluacji. Kontekstem rozważań są zidentyfikowane w literaturze przedmiotu elementy ekologicznej biblioteki. Metody – Wykorzystano badania niereaktywne w postaci analizy treści. Wyniki – Instrumenty oceny bibliotek w zakresie zrównoważenia środowiskowego nie uwzględniają wszystkich obszarów zidentyfikowanych jako elementy ekologicznej biblioteki. Kryteria oceny są różnie definiowane i w kon- sekwencji obejmują odmienne wskaźniki oceny. Wnioski – Istnieje konieczność wypracowania nowego narzędzia do oceny, monitorowania i kontroli działalno- ści bibliotek w zakresie zrównoważenia środowiskowego, bądź szerzej – zrów - noważonego rozwoju z uwzględnieniem kwestii środowiskowych. Wobec braku narzędzi do oceny aktywności bibliotek w zakresie zrównoważenia środowisko- wego niemożliwe jest śledzenie postępów w osiąganiu celów i prowadzenie ba- dań porównawczych.
Międzynarodowe czy zachodniocentryczne – geograficzne zogniskowanie wiodących czasopism naukowych z zakresu bibliotekoznawstwa i nauki o informacji
Authors: Osiński Zbigniew
Published: February 2025

Teza artykułu – W różnorodnych publikacjach można natrafić na in- formacje sugerujące, że przynajmniej w przypadku części dyscyplin naukowych w bazach Scopus i Web of Science dominują czasopisma nie tyle międzynarodo- we, ile reprezentujące stosunkowo wąskie środowiska uczelni z USA i Europy Zachodniej. W związku z tym autor postawił sobie następujące Cele  artykułu – 1. ustalić, czy czasopisma uznane za międzynarodowe i wiodące w dyscyplinie bibliotekoznawstwo i nauka o informacji (ang. Library and Information Science) po- siadają charakter międzynarodowy, czy raczej zachodniocentryczny; 2. bazując na dostępnych danych ustalić przyczyny takiego, a nie innego stanu rzeczy. Metody – Badaniu poddano czasopisma indeksowanie w bazie Scopus, a jednocze- sne indeksowanie w bazie LISTA EBSCOhost. Wyniki – Analiza ilościowa afiliacji autorów artykułów wykazała zdecydowaną dominację USA, Europy Zachodniej i Chin. Analiza porównawcza kilku innych zbiorów danych wykazała istotną korelację pomiędzy liczbą afiliacji członków zespołów redakcyjnych, adresami siedzib redakcji a liczbą afiliacji autorów artykułów. Jednakże bez dostępu do recenzji i decyzji redakcji nie możemy zbadać rzeczywistych powodów dominacji w dyscyplinie bibliotekoznawstwo i nauka o informacji autorów z bardzo ograni- czonej grupy państw. Możemy zaś wskazać na istotne ograniczenia w badaniach takiej problematyki.
