The objective of the present study was to evaluate the effectiveness of anthelmintics and their influence on the performance of beef cattle supplemented during the rearing period, carrying out a cost analysis of the different treatments. 120 Nelore animals were used, with an average of 9 months of age, 60 males and 60 females. The animals were distributed into 6 groups of males and 6 of females, five treated with anthelmintics and a control group, G1: Moxidectin 1%, G2: Levamisole Phosphate 18.8%, G3: Ivermectin 0.8% + Albendazole Sulfoxide 10%, G4: Albendazole 10%, G5: Fenbendazole 10%, G6: Control (saline solution). Individual weighing was carried out using an electronic scale, at the beginning of the experiment (D0), fourteen days later (D14) and at the end of the experiment (D90), with performance assessed through weight gain (GP). Fecal collections were carried out on the same days as weighing, with individual egg counts per grams of feces (OPG) and stool culture to identify helminth genders. Economic viability was calculated based on the price of the calf and total production cost. The data obtained was subjected to the 5% Tukey test and the effectiveness of the anthelmintics was evaluated using the RESO program. It is concluded that the anthelmintics evaluated were effective, with the exception of Ivermectin 0.8% + Albendazole Sulfoxide 10%, which showed anthelmintic resistance. The anthelmintic treatment provided the animals with better performance, with the greatest weight gain observed in animals treated with Moxidectin 1%, demonstrating better economic indices.

A agricultura familiar é responsável por grande parcela da produção de alimentos e prestação de serviços ambientais em nível mundial, sendo fundamental a manutenção da sua sustentabilidade. O objetivo do trabalho foi desenvolver um índice para avaliação da sustentabilidade em propriedades agrícolas familiares que considerasse com maior robustez a capacidade produtiva dessas propriedades, o Índice de Sustentabilidade Auera (ISA). Além de realizar um diagnóstico da sustentabilidade nas propriedades agrícolas familiares na região Sul do Brasil. O trabalho foi realizado em propriedades agrícolas familiares dos Estados do Rio Grande do Sul, Santa Cartarina e Paraná. Inicialmente foi analisado um banco de dados de 5.283 propriedades (pré-diagnóstico); em seguida foi desenvido e aplicado um questionário estruturado em 101 propriedades (diagnóstico) e por fim, foi realizado o levantamento detalhado de 182 indicadores em 11 propriedades. Foram avaliados indicadores das dimensões Social, Ambiental e Produtiva. Os resultados indicam que de forma geral, as propriedades apresentaram nível de sustentabilidade suficiente para a maioria dos indicadores. Contudo, existem oportunidades de melhoria em indicadores relacionados ao manejo de resíduos orgânicos e à qualidade da água; à conformidade ambiental e à capacidade de uso da terra; à conservação de áreas nativas; ao manejo e à conservação do solo e da água; ao manejo da acidez do solo; e à conservação e uso da agrobiodiversidade. Pode-se concluir que as propriedades ainda possuem um nível de sustentabilidade aceitável. Contudo, o ISA abaixo do limiar de sustentabilidade em alguns indicadores-chave, indicam uma tendência negativa para o futuro.

Published: August 2024

Heart disease is one of the most dangerous and largest killers in the world. Identifying heart disease early has a vast positive effect on patient outcomes and their quality of life. In this research, we try to identify heart disease using machine learning (ML) algorithms. ML algorithms have the highest probability of success if they work on a data set with extensive and diverse information about the given problem - in this case heart disease. There are multiple types of ML algorithms to test, so we can try many different ones on the data, making the results more precise. Even if there are many different algorithms to test, each machine-learning solution can yield different results depending on the dataset used and our target goals. The main goal of this study is to find the differences between individual ML algorithms being used in our specific case: which ML algorithm, or combination of algorithms, is appropriate to detect heart disease with high accuracy? The ML algorithms used in this research are the Naive Bayes Classifier, the Random Forest classifier, and the Support Vector Machine (SVM) algorithm. Furthermore, this study generates insights into these ML algorithms – if a particular algorithm’s model performs better than another on the dataset, analyzing this difference can help us understand what makes the model more suitable for diagnostic screening. Changing models’ hyperparameters or their pre-processing techniques allows for a more robust and reliable model that can be readily incorporated into a healthcare environment.

Published: August 2024

Pretreatment using Deep Eutectic Solvent (DES) was done to reduce the lignin content in oil palm empty fruit bunch (OPEFB). DES solution was prepared by combining Potassium Carbonate (K2CO3) as hydrogen bond acceptors (HBA) and Ethylene Glycol (EG) as hydrogen bond donors (HBD). This study aimed to obtain optimum conditions in the pretreatment process and determine the levels of lignin, cellulose, hemicellulose, and glucose in OPEFB. The pretreatment stage was performed at different temperature parameters, 100, 120, and 150°C, for 60 minutes to produce optimum conditions. Biomass pretreated with DES was hydrolyzed by cellulase complex to obtain glycose and xylose. The results showed that the pretreatment optimum condition value achieved with DES K2CO3:EG (1:10) at 150°C for 60 minutes was able to degrade lignin by 46,06%, hemicellulose by 4,08%, increase cellulose by 60,21%. The glucose and xylose content reached 58.48 g/l and 26.60 g/l, respectively. This sugar has potential for ethanol production from glucose and furfural production from xylose.

Published: August 2024

The manufacture of the Sasirangan home textile industry involves coloring and dyeing processes using synthetic dyes in large quantities. These contaminants of dyes and organic materials would cause high color and chemical oxygen demand (COD) contaminants values. This study aims to characterize the wastewater of batik-modified Sasirangan and determine the effect of current density and length of operating time on color removal and reduction of COD in Sasirangan home textile industry wastewater through the batch electrocoagulation process. The method used in this research is an electric current flowing in the same direction to the Sasirangan home textile industry wastewater in a reactor with dimensions of 310  180  240 mm3. The electrode used is aluminum alloy type 1100. The aluminum/aluminum (Al/Al) electrode is used in this electrocoagulation (EC) process, then connected to a direct current (DC) power supply. The experiment was carried out at room temperature using an electrode distance of 2 cm with variations in the time of the electrocoagulation process for 15–120 minutes. The experiment was repeated for variations in pH (4–9) with a current density of 3.5–5.5 mA/cm2. Furthermore, an analysis of the color removal and the decrease in the concentration of COD was carried out. The results showed that the contaminant content in Sasirangan home textile industry wastewater decreased significantly, whereas the optimal conditions for the EC reaction were determined using color and COD removal efficiency parameters. The decrease in color and COD concentrations occurred at a current density of 5.5 mA/cm2 with a pH of 4 for 120 minutes, around 1110 PtCo and 90.4 mg/L of COD, respectively

Mixed Hydroxide Precipitate (MHP), a metal precipitate with the dominant nickel and cobalt content in hydroxide compounds, can be leached as a lithium battery precursor. In this study, KMnO4 was used as an oxidant agent to increase the solubility of Ni and Co. The variation of the sulfuric acid concentration (0.5 - 1.5 M) as a leachate reagent, the concentration of KMnO4 (2.5 - 7.5 g/L), and the selective leaching temperature (60 - 80°C) were investigated. Solvent extraction using CYANEX 272 and D2EHPA was performed to separate the Ni, Co, and Mn. Atomic Absorption Spectrometry (AAS), Inductively coupled plasma mass (ICP-OES), and X-ray Fluorescence (XRF) were used to analyze the chemical compositions. At the same time, crystallographic analysis was observed with X-Ray Diffraction. It was observed that potassium permanganate increased the dissolution of Ni and Co to 91.3% and 85.4% but decreased the dissolution of Mn (37.53%) under the following conditions: 1.75 M sulfuric acid, 7.5 g/L potassium permanganate, and 60°C temperature. High purity of nickel crystal (99.64%) was observed with spontaneous nucleation due to the supersaturated nickel solution after solvent extraction with CYANEX 272. Thus, using permanganate ion as selective leaching of Ni and Co from Mn is promising.

Nowadays, electric cars use Al 5052 in the cooling pad of the battery coolant system. Corrosion behavior study of Al 5052 by coolant is essential in the automotive industry. Ethylene glycol is the main compound of the battery coolant system that can inhibit the corrosion process of aluminum alloys. The corrosion inhibition performance of ethylene glycol (EG) for Al 5052 surface in 3.5% NaCl solution has been studied using electrochemical measurements such as potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) in various concentrations of EG up to 50% and a temperature range from 30oC to 60oC. Based on results, EG can inhibit the corrosion process of Al 5052. The corrosion rate (CR) of coolant containing EG decreases with increasing that concentration in various temperatures, and the CR of the coolant rises with the increased temperatures. The inhibition efficiency of coolant boosts with the increase in EG concentration in each operational temperature and the highest up to 75% at 60oC with 50% of EG concentration.

A Esclerose Múltipla (EM) é uma doença autoimune desmielinizante do sistema nervoso central (SNC), caracterizada por uma interação de fatores genéticos e ambientais. A vitamina D (VD) é produzida pela pele exposta à radiação ultravioleta B ou obtida de fontes alimentares e influencia no processo inflamatório, diminuindo a produção dos mediadores pró-inflamatórios O objetivo deste trabalho é realizar uma revisão integrativa da literatura a respeito dos efeitos do tratamento com a VD em pacientes com EM. A metodologia envolveu a busca de artigos científicos no PubMed e Scielo, nos idiomas português e inglês e 40 artigos foram selecionados. A EM ocorre por um processo de destruição da mielina e degradação dos axônios dos neurônios onde há uma desregulação do sistema nervoso central mediada por células do sistema imune, como os linfócitos B e T e os macrófagos, o que aumenta o processo de desmielinização. Estudos demonstram que o tratamento dom VD diminui a incapacidade e melhora a caminhada cronometrada de pacientes com EM. Por outro lado, outros estudos demonstram que este tratamento não causa diferença significativa na taxa de recaída anualizada, escala expandida de status de incapacidade, componentes compostos funcionais da EM, força de preensão ou fadiga. Apesar de os estudos ainda serem inconclusivos, o processo fisiopatológico que envolve a EM está intimamente ligado ao metabolismo da VD. Portanto, tornam-se necessários mais pesquisas que visem a melhoria da qualidade de vida de pacientes com EM.

Introduction: According to WHO data, it is estimated that more than 40 million people need palliative care every year. This includes patients with cancer, heart disease, lung disease, and neurodegenerative diseases such as Alzheimer's disease. Palliative patient care often involves support from the family, and this condition can affect the patient's quality of life as well as the family's own well-being. Many families do not have sufficient knowledge about palliative care, including how to manage symptoms, provide daily care, or understand the patient's emotional needs
Objective: Participants in this activity totaled 35 people
Method: The method for this community service activity is continuous counseling
Result: Based on the training results, data showed that there was an increase in knowledge with the average increase in post-test results being 15.2 with the highest score on the post-test being 98.
Conclusion: The conclusion of community service regarding increasing family knowledge in palliative care has succeeded in increasing family understanding and skills in caring for family members who need palliative care. Families now better understand the concept of palliative care, including aspects such as pain management, symptom control, and emotional support. These activities also help reduce the stigma that may exist regarding palliative care and overcome the uncertainty that families often feel. Better knowledge allows families to feel more prepared and confident in carrying out care

Authors: Trache Najia , Salem Mohammed , Khelfi Mohamed Fayçal
Published: August 2024

In recent years, image watermarking has become the most active research in the information hiding field. This paper presents an application of a computational intelligence technique to obtain robust and secure image-watermarking schemes for data image transmission. The optimization goal is achieved via a new robust method based on the hybridization (in the digital domain) of the image-watermarking scheme using Discrete Wavelet Transform (DWT) and Singular Value Decomposition (SVD). The Forensic-Based Investigation (FBI) optimization algorithm is considered to search for the best scaling factor and the appropriate location for the watermark insertion. The Arnold Transform (AT) encryption is also introduced to enhance the watermark image process security. To show the efficiency of the proposed schemes, several watermarked images are subjected to several attacks, and their imperceptibility and robustness are checked via structural similarity index measure (SSIM) and Normalized Correlation Coefficient (NCC) where the proposed schemes provide competitive simulation results. Statistical analysis is also carried out to prove the performance of the used optimization algorithm.

Harnessing Drones for Snow Leopard Conservation
Authors: Jackson Rodney
Published: August 2024

Censusing snow leopard prey species like argali, ibex or blue sheep, is time-consuming, expensive, and challenging. We tested thermal-sensor-equipped drones to census ungulate populations in Mongolia’s Ikh Nart Nature Reserve.  In 2019 and 2022 we used drones to detect wild ibex and argali.  Here we report on 2022 findings: ~400 km along 5 fixed transects totaling forty-three missions, including several double count surveys. Drones detected 259 prey animals and 265 livestock; on average, 34% of all sightings were in areas obscured by topographic features from ground-based observers. Overall, tests reinforced the utility of drones for counting ungulates, along with highlighting important issues and future advances for supporting largely autonomous prey surveys. We recommend biologists build upon existing technology to attain an inexpensive, easy to use, and field ready set of equipment and procedures that can reliably improve or replace traditional walking or transect count methods for large prey species.

Published: August 2024

The COVID-19 pandemic has inflicted profound disruptions on global economies, with significant repercussions for agriculture and rural communities. This study investigates the impact of COVID-19 on farmers through factor analysis, focusing on socio-economic dynamics and resilience in the agricultural sector. Data was collected from rural communities through focus group discussions, personal and key informant interviews in Chikkaballapur district, Karnataka, India, during the peak of the pandemic. Factor analysis was employed to identify underlying variables and explore the relationships among them. Results indicate that the pandemic has exacerbated existing challenges faced by smallholder farmers, disrupting agricultural activities and livelihoods. Factors such as education, family size, and farm size emerged as critical determinants of resilience, emphasizing the importance of socio-economic empowerment and resource access. Additionally, infrastructure and resource availability, represented by factors like water resources and service sector facilities, played pivotal roles in shaping agricultural outcomes. Insights from the principal component analysis (PCA) provide valuable guidance for policymakers and practitioners in devising targeted interventions to mitigate challenges and capitalize on opportunities in rural areas. By understanding the key factors driving socio-economic dynamics and agricultural productivity, stakeholders can foster sustainable development and resilience in agricultural communities amidst unprecedented global crises like COVID-19. The study underscores the urgent need for evidence-based strategies to address the multifaceted impacts of the pandemic, ensuring the well-being and resilience of farmers and rural communities in the face of uncertainty and adversity. Based on the findings, it is recommended that policymakers prioritize socio-economic empowerment and infrastructure development in rural areas to enhance resilience and sustainable development in agricultural communities, especially during global crises like the COVID-19 pandemic.
Effect of 3D Printing on the Mechanical Properties of FDM Printed Electrical Components

Published: August 2024

The Additive manufacturing (AM) technology, also known as 3D printing, reduces production time, enhances the production process and quality, lowers costs, and achieves several other goals when producing solid, three-dimensionally created structures for the application of digital information, medical equipment, automobile, airplane, and many more. By giving the necessary instruction through a human-machine interface, the techniques used to build three-dimensional structures allow for adding material in successively thinner layers, enabling manufacturing objects in almost any shape or geometry.
The polylactic acid filament was used as the feedstock to create a range of 3D-printed electrical parts. The components were created using an FDM 3D printer after being designed in Solidworks. Samples of printed materials were subjected to experimental testing to ascertain their densities, tensile strengths, flexural strengths, thermalgravimetric analyses, and Fourier transform infrared spectroscopy (FTIR) values. Heating PLA polymers change their mechanical properties. The experiment run utilizes the printed samples to compare the findings with the standard values for each parameter.
The production of locally produced 3D printing feedstock and waste management are the two biggest obstacles to 3D printing in Nigeria that this innovation will overcome. This strategy, which would reduce the importation of spare parts, will benefit the industrial sector. Less equipment will need to be discarded because there will be fewer components. Thus, it may be possible to achieve sustainable development goals for infrastructure, innovation, and business.
A Study on the Reasonableness of Housework Compensation from a Comparative Law Perspective
Authors: Chungang Miao
Published: August 2024

Traditional family relationships in law are characterized by patriarchy, where women's housework is a natural division of labor. In contemporary society, both China and Western countries emphasize the reasonableness of housework compensation from theoretical and institutional perspectives. From a comparative law perspective, China's housework compensation system, based on recognizing the value of housework, was officially established after several amendments to the Marriage Law. This legislative evolution is intertwined with changes in legal approaches to resolving marital disputes. The recognition of housework compensation in foreign laws varies due to differences in legal values and legislative traditions, represented by the German and American legal systems. German law, as a representative of the civil law system, adheres more to the employment theory in marital relationships, while American law views marriage more as a partnership. From a legislative perspective, the analysis of the reasonableness of housework compensation in Chinese law should be conducted in the context of the joint property system of spouses. The analysis path should consider the changes in the approach to resolving marital disputes in recent years. Divorce cases have shifted from the value orientation of divorce freedom to a judicial approach that appropriately returns to the family principle. This change in judicial values will in turn affect the perception of housework compensation.

Microplastic (MP) contamination has emerged as a serious worldwide issue. Human activity, commercial operations, and fishing are all concentrated around the coast, resulting in high levels of fish MPs contamination. This preliminary investigation aims to examine MP accumulation in commercial fish caught in the Vellar estuary region. Fish samples were collected from the estuary, and MPs in the gills and gastrointestinal tracts of three commercial fish species were analyzed for quantity, type, shape, and color using standard laboratory techniques. MPs particles were found in 2.55-4.35 items per individual fish, with an overall average of 3.2 particles in the gills and 5.5 in the gastrointestinal tract. The majority of the MPs were blue and green fibers with a diameter of 0.5-1 mm. Fragmented pieces of MPs and fibers were abundant in the gut. These findings demonstrated the extent of MPs contamination in Vellar estuary fish tissues, serving as a baseline for MPs loading in the estuary. This study has significant implications for food safety, highlighting the dangers of MPs in fisheries and aquaculture. It also identifies knowledge gaps in the long-term effects of MPs, suggesting a need for further research in this sector.

In this study, the insecticidal effectiveness of agricultural waste ashes of sawdust, rice husk, groundnut shell, maize cob, and wheat straw against Sitophilus oryzae in stored rice grains was investigated. The research, conducted to assess grain damage, weight loss, and weevil perforation index caused by S. oryzae over intervals of 30, 60 and 90 days. The ashes were applied at a rate of 2 gm per 100 gm of grains. Over a 90-day period the untreated control exhibited the highest grain damage (33.80%) and weight loss (14.23%). Among ash treatments, sawdust ash resulted in the highest grain damage (18.40%) and weight loss (12.47%), whereas groundnut shell ash was the most effective, showing the lowest grain damage (12.87%) and weight loss (8.53%). The chemical insecticide Chlorpyrifos 48EC maintained complete protection with 0% grain damage and weight loss. The Weevil Perforation Index (WPI) was significantly lower in groundnut shell ash (9.27) compared to other ash treatments, emphasizing its effectiveness in preserving rice quality.

Today's world faces great challenges because of the knowledge era and globalization. Key issues, such as environmental degradation, call for an urgent need to raise awareness among the workforce to act in a more planet-friendly manner. Recent studies reveal that 6 of the 9 planetary limits that allow life on Earth have already been exceeded. UNESCO suggests that a paradigm shift can only be achieved through competency-based education, where key sustainability skills that cut across specific competencies are coerced and help employees act consciously. This study tries to assess the extent to which the competencies currently requested to occupy the position of jurist are aligned with frameworks of competences adjusted to sustainability. To achieve this, a monitoring was carried out in the legal area of Internet work bags using web scraping techniques, the search produced 291 records of which 85 competencies were obtained, which were reduced to 14 by deductive methods with the help of ATLAS.ti. In addition, theoretical relationships were sought between the skills recovered and the sustainable competencies considered in the framework proposed by UNESCO in 2017, with the aim of obtaining data and obtaining statistics with the help of EXCEL and R Studio, and with this in mind establishing convergences. The findings suggest that employers prefer technical competencies (58.75%) over soft ones, more focused on sustainable performance (41.25%). On the other hand, it may be suggested that the skills collected could be key to developing scales of measurement of sustainable performance in employees carrying out legal tasks.
