Phát triển một mô hình vật liệu đất có thể mô phỏng ứng xử của đất dưới tải một chiều
Authors: Minh Huỳnh Nhật
Published: April 2024

Phát triển mô hình vật liệu đất ngày càng trở nên phổ biến hiện nay, bởi đất là một vật liệu dạng hạt có ứng xử khác nhau với mỗi điều kiện tải khác nhau. Đã có nhiều nghiên cứu về mô hình vật liệu đất hiện nay. Tuy nhiên, hầu hết các mô hình vật liệu đất này có những nhược điểm đặc thù như là các mô hình đất này chỉ mô phỏng tốt một số trường hợp tải nhất định hoặc những thông số đầu vào của mô hình đó phải bị điều chỉnh thì kết quả mới gần với kết quả thí nghiệm của mẫu đất. Trong nghiên cứu này, một mô hình vật liệu đất được phát triển dựa trên một mô hình vật liệu đất hiệu quả và phổ biến hiện nay, và chú trọng vào việc khắc phục tình trạng hệ số Poisson bị điều chỉnh khác với các thí nghiệm thực tế. Mô hình cải tiến này sẽ dùng hệ số Poisson thực tế của mẫu đất để làm giá trị cho hệ số Poisson nhập vào mô hình vật liệu và phương trình về độ tăng cứng và phương trình về độ giãn nở sẽ được điều chỉnh. Thông qua việc so sánh kết quả mô phỏng của hai mô hình gốc và mô hình cải tiến với kết quả thí nghiệm, tác giả quan sát được mô hình vật liệu cải tiến này có thể khắc phục tình trạng mô phỏng thái quá và tình trạng đánh giá thấp về độ trương nở cũng như độ cứng của đất trong mô hình gốc khi sử dụng đúng giá trị hệ số Poisson của đất trong thí nghiệm. Kết quả này đóng vai trò quan trọng trong việc phát triển mô hình vật liệu đất, giúp các nhà nghiên cứu có thể phát triển tiếp tục mô hình vật liệu này để có thể mô phỏng được các ứng xử khác của đất.
Using the altman’s Z-score formula to assess the financial situation of military construction enterprises in Vietnam
Authors: Hoang Thi Khanh Van  , Pham Duc Phong  , To Thi Huong Quynh
Published: April 2024

Military construction enterprises are classified as defense economic enterprises and are subject to regulation by two legal systems: the State’s legal system for regulating enterprises in general and provisions of law on national defense. As a result, military construction enterprises have unique characteristics that distinguish them from other enterprises. These characteristics include the organizational form, capital mobilization form, depreciation management, receivable management, and profits distribution of military construction enterprises. This study uses data from financial statements of 22 military construction enterprises from 2015 to 2019 including both joint stock companies and 100% state-owned enterprises to calculate the Altman Z-score formula. The Altman Z-score is a linear combination of four or five common business ratios, weighted by coefficients. Z-scores are used to predict corporate defaults and an easy-to-calculate control measure for the financial distress status of enterprises with high reliability. Due to the difference between military construction enterprises and conventional enterprises, the Altman model is applied in the article to evaluate the financial status of military construction enterprises. The research results show that the decrease in business efficiency causes the ratio of revenue and profit to total assets of military construction enterprises to decrease sharply, the proportion of working capital in total assets is low. Furthermore, the ratio of equity to total debt is the most important reason to make low Z-score that means prediction of a high risk of bankruptcy in military construction enterprises. An evidence base from the research results is used for making a number of proposals to reduce the risk of bankruptcy and improving the efficiency of financial management of enterprises.

Understanding the determinants behind the exercise habits of urban residents, encompassing aerobic activities and training regimens, is of paramount importance for informed public policy formulation and urban planning. The utilization of mobile fitness app data, which characterizes exercise behaviors concerning time and location, offers a unique avenue for unveiling the key factors influencing physical activity. In this study, we conducted a comprehensive analysis of mobile fitness app data, collecting information from over 14,000 cellular towers and studying the exercise patterns of 4,000 users. Our rigorous investigation reveals that temporal elements, such as the day of the week and the time of day, wield significant influence over human exercise preferences. For instance, data shows that on weekdays, there's a 20% increase in exercise app usage during the evening hours (6 PM - 9 PM), while weekends see a 15% spike in early morning activities (6 AM - 8 AM). Geographical location also emerges as a prominent influencer. Our analysis indicates that individuals residing closer to parks or fitness centers exhibit a 25% higher likelihood of engaging in outdoor workouts. Importantly, personal income levels have surfaced as a fundamental factor significantly shaping exercise habits. Data suggests that individuals with higher incomes allocate, on average, 10% more of their time to structured training regimens. This research contributes essential insights for urban policy development and city planning, aimed at fostering a healthier and more physically active urban populace.

Published: April 2024

Cloud computing is often regarded as a great innovation due to the increasing demand for endless storage space and reliable retrieval services. Several works have been developed on ranked multi-keyword search over cloud data with numerous data owners concerned about privacy. However, most of these methods can be broken by a clever attacker using a combination of a keyword guess and an equivalency test. Also, when searching across data from many data owners, they can't reliably return the top k results to the users. The unreliability of search results and the potential for the exposure of critical keyword information are two obvious drawbacks. To address this issue, we first propose a novel efficient ranked multi-keyword retrieval scheme with keyword privacy for multiple data owners, allowing the cloud server to perform multikeyword search over the cloud data and then return the top-k ranked search results to data users without leaking any keyword and trapdoor information. Furthermore, we demonstrate through stringent security analysis that our method is safe from both internal and external threats. Finally, the results of the performance evaluation show that our scheme outperforms other ranked multi-keyword search systems.

Authors:   Atma Malik Institute of Technology and Research, Shahapur, Thakare Mr.Dipesh
Published: April 2024

Significant growth in the consumption of plastic products is observed all over the world in recent years; this has contributed to increasing the production of plastic waste. Disposal of plastic is a challenging task. Because plastic waste can take anywhere from 20 to 500 years to decompose, and eventhen, it never fully disappears; it just get smaller and smaller. Hence it is necessary to reduce the amount of production of plastic as well as disposal and reuse of plastic is mandatory. As decomposition of plastic is a serious problem as it takes very long time and adversely affection the environment in many ways so reuse of plastic waste in the production of concrete or mortar appears as an environmentally friendly solution for getting rid of plastic waste, due to its ecological and economic advantages and we can use it in construction, where we need life of structure to be improved. Furthermore, it leads to a decrease in plastic waste in landfills. Several studies presented the properties of cementitious composites (mortar and concrete) containing different types of (PWD) Usage of these plastic waste materials helping in dual role by minimizing of concrete and by using the waste materials that are affecting the environment. The other advantage of using these waste materials is that they are helping improving the properties of concrete.This study summarizes the previous studies until 2019, discussing the use of recycled plastic aggregate as aggregates in cementation composites and its impact on the compressive strength. In this study we are going to replace the fine aggregate and coarse aggregate by plastic aggregate with 2.5%, 10% and 25%, then specimens are tested and compared with a control specimen of 0% plastic in terms of compressive strength. We will also do the comparative study of replacement of fine and coarse aggregateand going to find that which replacement is better.

Fractional and Unitary Electric Charges I: Classical Foundations of Quantum Effects
Authors: Obande Ogaba Philip
Published: April 2024

Numerical value of the atom’s electrical/electromotive charge emerges naturally upon expressing its definitive e-m oscillation frequency ν as an exponent of eight, 8ν  (‘octave quantum’). This simple procedure realizes, for each element, accurate values of the established quantum numbers. It is revealed that unlike others, the spin quantum number ±½ is not an ‘octave quantum’, it actually turns out an exponent of a field coupling that manifests atomic mass. Octave quanta of frequencies of atoms of the second and third (invisible unknown) elements of nature’s chemical periodicity, “blackton” Bl and “boston” Bs, (8⅓, 8⅔)  manifest observational fractional one-third 1/3  and two-third 2/3  electrical charges normally associated with ‘quarks’. Based on the concept of ‘octave quantum’ the author uses periodic arrangement of the chemical elements to present a unique account of established quantum numbers, it facilitates a deeper insight into factors responsible for unusual valences commonly encountered among transition elements. It is concluded that the ease with which the procedure reproduces established quantum numbers strongly suggests an intrinsic classical origin of observational quantum characteristics.

Authors: Singh Rupa , Cabrera Constanza Isabel Bravo , Singh Rajeev Kumar
Published: April 2024

The study investigated the geographical attributes, distribution, and determinants of pelvic organ prolapse (POP) in Nepal to comprehend the underlying factors contributing to its high prevalence in the region. Conducted in the Panchapuri municipality of midwestern Nepal, this cross-sectional study surveyed 103 married women aged 20–49 years using a semi-structured questionnaire. Participants were randomly selected from four health facility catchment areas in equal proportions. Descriptive statistics presented the data while binary logistic regression models assessed factors associated with POP. Participant allocations were mapped using ArcGIS, with shapefiles obtained from official sources. The study revealed a POP prevalence of 37.9%, with housewives exhibiting a significant association compared to businesswomen (AOR: 5.291; 95% CI: 1.046, 26.775). Constipation during pregnancy was significantly associated with POP (AOR: 9.104; 95% CI: 2.210, 37.501), while multipara women with a parity of four or more were 7.8 times more likely to have POP. Interestingly, geographical attributes like altitude, slope, and climate showed no association with POP. The findings underscore the significant association of POP with factors such as housewives, pregnancy-related constipation, and multiparity. Addressing these determinants through targeted research is vital in alleviating the burden of POP. This study emphasizes the urgent need for interventions, policies, and healthcare support, particularly focusing on maternal health and occupational well-being among rural housewives in Nepal.
¿Un ataque con misiles nucleares? El proyecto RYaN y los mitos de la Segunda Guerra Fría
Authors: Colom Piella Guillem
Published: April 2024

La operación RYaN continúa siendo un misterio. El relato mayoritario considera que este proyecto diseñado por Yuri Andropov para descubrir los preparativos de un ataque nuclear por sorpresa arrancó en 1981 y se convirtió en la máxima prioridad del KGB en 1982. RYaN habría tenido un papel central en la crisis nuclear de noviembre de 1983, coincidiendo con los ejercicios aliados Able Archer 83 y el inminente despliegue de los misiles Pershing II en Alemania. Esta tesis parece estar apoyada por la sucesión de los acontecimientos, los relatos de sus protagonistas y por la documentación estadounidense y británica desclasificada. Sin embargo, es probable que sea errónea. Aunque los archivos soviéticos continúan clasificados, en los últimos años se han reconstruido y catalogado numerosos informes de la Stasi alemana que tratan sobre este proyecto. Junto con otras fuentes, el artículo revisa estos planteamientos y propone una interpretación alternativa sobre RYaN. Este proyecto que arrancó en 1979 para evaluar el empleo de ordenadores en el análisis de inteligencia, no empezó a operacionalizarse hasta 1984 y, posiblemente, nunca alcanzó la plena operatividad. Al no estar operativo durante Able Archer 83, este difícilmente habría informado de un hipotético ataque nuclear aliado. Por lo tanto, ni hubo ninguna crisis nuclear ni tampoco noviembre de 1983 fue el punto más caliente de la Segunda Guerra Fría. Ello abre la puerta a reinterpretar este periodo histórico.
Contributions of homestead agroforestry during the war in Tigray, Ethiopia

Published: April 2024

Rapid population growth and unplanned settlement and resettlement has increased agricultural development in Ethiopia's Tigray Region, causing forest and land degradation. Governmental and non-governmental organisations have responded to this by establishing exclosures and communal grazing lands to foster natural regeneration. Their efforts have significantly enhanced environmental recovery, reduced soil erosion and increased water recharge, but challenges remain. Transplanted seedlings have low growth and survival rates, and economic gain is hampered by biased benefit sharing and ownership. Additionally, the war that began in Tigray in 2020 has made it difficult to implement watershed-level communal plantations. Farmers and their families have, therefore, adopted homestead agroforestry, an integrated tree-crop-animal production system. The Relief Society of Tigray (REST) assessed farmers' experiences with homestead agroforestry practices and found that, in addition to providing beneficial ecosystem services, homestead agroforestry had contributed significantly towards income generation, food production and energy supply, which proved especially vital in times of war and extreme poverty. The tree species Ziziphus spina-christi was even named "the tree that saved lives" as its fruit became a staple food for those affected by the war. Homestead agroforestry also reduced pressure on forests by meeting people's increasing need for biomass energy, helping to curb deforestation. Despite its many benefits, there remain challenges to developing homestead agroforestry, but available remedies and recent advancements have led district leaders to commit to making homestead agroforestry their priority agenda. Regional strategic documents, technical and financial support, and capacity strengthening are now needed to propel homestead agroforestry to improve more people’s livelihoods and further mitigate forest degradation and land loss.

Authors: Hamza Idris Yahaya
Published: April 2024

Malaria is a serious public health problem in Sub-saharan Africa including Nigeria, with the potential to increase significantly in response to seasonal changes. The aim of the study was to determine the influence of seasonal variations on the prevalence of malaria infection among outpatient attending Muhammad Abdullahi Wase teaching hospital Kano state, Nigeria. The objectives were to establishing the correlation between malaria infections and seasonal variations, and also determining the prevalence during different seasons, and evaluating the gender distribution of infection. The study was carried out from January to December, 2019, involving the use of microscopic examination of 840 blood samples using thick and thin film methods. Out of 840 patients examined (57.1%) had a malaria infection. Wet season had the highest prevalence rate of malaria infection (33.2%) than dry season (23.9%).There was a statistically significant differences (P<0.05) in the prevalence rate of malaria infection in relation to season. In relation to the gender females had higher (31.9%) prevalence rate of malaria infection than males (25.2%) and there was no significant difference in the prevalence rate of the infection in relation to sex (P>0.05). Concerning age groups, patients aged 26-30 years had the highest prevalence rate (9.04%), while those aged 40 and above had the lowest. However, the variation in prevalence among age groups was not statistically significant (P>0.05).This study confirmed that malaria infection still remains an important public health problem in the study area. Therefore, full implementation of adequate public health measures need to be undertaken to mitigate the endemicity of the disease, such as the Roll Back Malaria control Strategies as well as health education and environmental modifications are advocated is recommended.

Published: April 2024

The purity and content of DNA extracted from the sample is important during PCR analysis. In the conditions of our country, there are many cases of working on samples that do not meet the requirements for some reason. In such cases, there is a need to further test and develop other sensitive methods. The upstream-primer multiplex PCR (UP-mPCR technique) is known for its high specificity and fidelity, and has been used for detecting multiple food borne pathogens, meat species testing and detecting different genetically modified organism (GMO) insertions in a plant genome. The purpose of this experiment is to apply the UP-mPCR method on DNA samples that do not meet the quality requirements, and to test it on domestically produced diagnostics.We combined UP-mPCR with fragment analysis on DNA capillary electrophoresis genetic analyzer by applying fluorescent labelled upstream primers which were tested by amplifying 8 STRs on 23 low-quality equine gDNA samples. These samples had formerly undergone unsuccessful testing by domestic equine genotyping 15-plex kit. Single trial of UP-mPCR on the same samples showed successful amplification and detection of amplicons from 4-6 STRs, and their alleles were genotyped. Combining UP-mPCR and DNA capillary electrophoresis can be helpful in extreme situations such as having limited amounts of sample, or a shortage of multiple fluorescent dye oligonucleotides. There is no former report about the same method as combining UP-mPCR with fragment analysis.

The development of an automated crop monitoring system using computer vision and machine learning techniques can help to reduce the manual labor involved in crop management and enhance crop yield. This paper proposes a crop monitoring system that utilizes a camera mounted on a mobile robotic platform to capture images of crops at regular intervals. The images are analyzed using computer vision algorithms to detect and track plant growth, pest infestations, and nutrient deficiencies. Machine learning techniques are then applied to the data to predict crop yield. The system is designed to be scalable and can be deployed on a variety of crops, making it suitable for use in large-scale agricultural operations. Preliminary results demonstrate the system's effectiveness in detecting plant growth with an overall accuracy rate of 95%. The proposed system has the potential to significantly improve crop management practices and increase crop yield, thereby contributing to sustainable agriculture development.
Improving the Learning Performance of Client’s Local Distribution in Cyclic Federated Learning

Published: April 2024

Cyclic federated learning based on distribution information sharing and knowledge distillation (CFL_DS_KD) aims to address the challenges of non-iid data distribution and reduce communication requirements. However, when client data is extremely heterogeneous and scarce, it becomes challenging for clients to fully learn the distribution of local data using GANs, thereby affecting the overall model performance. To overcome this limitation, we propose a transfer learning approach where clients first pretrain their generators on a source domain and then fine-tune them on their local datasets. Our results on the classification of Alzheimer’s disease demonstrate that this method effectively improves client distribution learning performance and enhances the overall model performance.

O estudo aborda as doenças crônicas não transmissíveis (DCNTs) como uma significativa causa global de mortes, especialmente no Brasil, destacando fatores de risco modificáveis como sedentarismo e alimentação inadequada. O estudo tem como objetivo associar os estágios de motivação para mudança de comportamento alimentar (EMCA) e de prática de atividades físicas (EMAF) com o perfil socioeconômico, de saúde e de estilo de vida de adultos em Estratégia de Saúde da Família – ESF. Esta pesquisa caracteriza-se como um estudo quantitativo descritivo, desenvolvido na cidade de Ibirubá – RS em uma Estratégia de Saúde da Família. A população foi composta por 3472 adultos (mais de 18 anos) e a amostra incluiu 44 adultos. Para a coleta dos dados foram utilizados questionários fechados. Os dados foram analisados por meio da estatística descritiva e inferencial, e a associação entre os grupos nos diferentes EMCA e EMAF foram analisadas por meio do teste Qui-quadrado ou Exato de Fischer (p ≤ 0,05). A maioria dos participantes estava no estágio de preparação para a prática de exercícios (79,5%) e ação para mudanças alimentares (88,6%). No EMAF de preparação, observou-se autopercepção de saúde positiva, uso frequente de medicamentos, excesso de peso, RCQ alto/muito alto e DCNT. No estágio de preparação para atividade física, houve avaliações positivas em vários componentes do estilo de vida, exceto pela atividade física, com diferença significativa entre os grupos. No EMCA, a maioria em ação apresentou autopercepção de saúde boa, sem uso de medicamentos, eutróficos, RCQ moderado e sem DCNT. Predominância de mulheres e idosos foi notada, sem diferenças socioeconômicas nos EMAF e EMCA. Em resumo, os resultados destacam padrões nos estágios de mudança, enfatizando a necessidade de abordagens específicas para promover atividades físicas e mudanças alimentares.

O feijoeiro necessita de adubação nitrogenada para otimizar seu crescimento. Porém, é preciso estabelecer a dosagem adequada para a cultura. Objetivou-se avaliar o desenvolvimento de feijoeiro submetido à doses e tipos de fertilizantes nitrogenados em Latossolo Vermelho distrófico típico. Montou-se experimento em vasos, sendo os tratamentos doses de N (0, 15, 30, 60, 120 e 240 kg ha-1) na forma de NH4SO4, ureia e MAP. Os adubos aumentaram o desenvolvimento do feijão. Porém, a maior dose de N reduziu o desenvolvimento vegetal. O maior desenvolvimento de feijão ocorreu com aplicação de 160, 197 e 136 kg ha-1 de MAP, ureia e NH4SO4, respectivamente. Os teores de fósforo e potássio foram maiores com doses baixas (0 a 30 kg ha-1) e alta (240 kg ha-1) de N.

As competências gerenciais são elementos primordiais levados para o mercado de trabalho pelos estudantes de Hotelaria. Tais competências tornam os recém-formados aptos a desempenharem suas atribuições profissionais conforme contexto teórico aprendido ao longo da formação e ainda com base nas habilidades comportamentais desenvolvidas por intermédio de atividades práticas durante o contexto acadêmico. O objetivo desta pesquisa foi analisar a percepção dos discentes do Curso de Hotelaria da Universidade Federal do Maranhão (UFMA) sobre o desenvolvimento de competências gerenciais na sua formação em relação ao projeto político pedagógico do curso. Nesse sentido, esta pesquisa é de caráter exploratório e de abordagem quali-quantitativa, tendo como objeto alunos do curso de Hotelaria da Universidade Federal do Maranhão em vias de se formar. Os dados foram levantados por meio de questionários com perguntas abertas e fechadas direcionadas aos discentes. As informações obtidas foram organizadas em formato de gráficos e quadros, aplicando sobre os dados quantitativos a análise de estatística descritiva e análise do discurso para os dados qualitativos. Foi realizada também a análise de dados secundários por meio de levantamento documental dos projetos políticos pedagógicos do curso em questão no período de 1987 a 2019 para entender o contexto de formação desse discente. Foi possível identificar as competências gerenciais com maior necessidade de atenção e desenvolvimento por parte dos discentes. As competências: planejamento, organização, liderança, comunicação, tomada de decisão, compreensão de mercado, trabalho em equipe e hospitalidade se destacaram positivamente em relação ao seu desenvolvimento ao longo do curso, apontando congruência entre o projeto e a autoavaliação dos alunos. Há um destaque especial para a competência relacionada à hospitalidade sendo a de maior destaque disparado em relação às demais. Em contraponto, gestão de recursos e sobretudo os idiomas se mostraram como competências gerenciais poucas desenvolvidas pelos sujeitos da pesquisa, embora sua importância tenha sido destacada. Sendo idiomas a de maior discrepância.

O potássio é o segundo macronutriente mais exigido pela cultura da soja e desempenha papel vital no processo fotossintético das plantas. Assim foi estudado o crescimento de cultivares de soja, em solo submetido à aplicação de doses de K. O experimento foi conduzido em casa de vegetação no Instituto Federal do Amapá – IFAP/Campus Agrícola Porto Grande. O delineamento experimental foi o inteiramente casualizado, em esquema fatorial 5x2, com quatro repetições. Os fatores foram constituídos de cinco doses de K (0, 45, 90, 135 e 180 kg ha-1 de K), na forma de cloreto de potássio e duas cultivares de soja (BRS Sambaíba RR e BRS 8781). As unidades experimentais foram compostas por vasos plásticos, contendo plantas de soja, com 7 dm3 de solo, coletado na camada arável de um Latossolo Amarelo Distrófico de textura franco-arenosa. As variáveis analisadas, foram: altura da planta, diâmetro do colmo e matéria seca da parte aérea, das raízes e total das cultivares de soja. A dose de 90 kg ha-1 de K proporciona maior crescimento e produção de matéria seca da soja. A cultivar Sambaíba RR proporciona maior desempenho em crescimento das plantas de soja, em comparação a cultivar BRS 8781.
