Severe Vulvar Myiasis Case In A Crossbreed Limousin Cow

Background: Myiasis is caused by the infestation of Diptera fly larvae in vertebrate animals. In cases of myiasis, larvae will eat living or dead tissue, thereby expanding the infestation and infection of the host. Myiasis is a significant economic problem due to decreased productivity and tissue damage. Purpose: This study seeks to provide insights regarding managing and treating myiasis cases in cattle. Cases(s): The 4-year-old female Limousin cow was in the gestation period and kept in Buluagung Village, Pesanggaran, Banyuwangi. Based on the owner's statement, the cow experienced a decrease in appetite, and there were wounds in the vulva area accompanied by larvae, which had been present for five days. The clinical findings revealed an open wound that was red in color and soft in consistency, and there was an unpleasant odor in the vulva area. An infestation of Diptera fly larvae accompanied this. After the initial extraction of maggots, necrotic tissue, edema, friable tissue, and erythema were evident in the vulvar region and introitus. Case Management: Treatment carried out on the case cow involved cleaning the wound using 0.9% NaCl and removing both necrotic tissue and any larvae from the vulva wound using tweezers. The cow received an intramuscular injection of an analgesic and antipyretic (Sulprodon®) 7 mL, antihistamine (Prodryl®) 3 mL intramuscular injection, antibiotic (Limoxin-LA®) 10 mL, and multivitamin (Injectamin®) 7 mL. Conclusion: The vulvar myiasis in this cow was successfully cured with no more larvae found, and the wound dried out.

Aerobic Thiols Oxidative Coupling to Disulfides over Robust CoOx Nanoclusters Confined within Hierarchical Silicalite-1 Zeolite.

Disulfide is an important organic reagent and synthetic intermediate that is widely used in organic synthesis, polymers, and other fields, but its synthesis still suffers from many environmental pollution and economic problems. Here, we present an environmentally friendly and efficient base-free aerobic oxidative thiol coupling catalyzed by heterogeneous CoOx nanoclusters entrapped in hierarchical silicalite-1 zeolite, synthesized by combining silane pore expansion and metal coordination methods under hydrothermal conditions. It is confirmed that open hierarchical channels favor mass diffusion, and the chemical valence of Co species in CoOx/h-S-1-H is +2, which is different from that of Co3O4 particles in CoOx/h-S-1-I. CoOx nanoclusters, are strongly fixed in the channels of silicalite-1 zeolite via Co-O-Si bonds, which is of great importance for the high catalytic activity in both symmetrical and unsymmetrical oxidative thiol coupling reactions. After recycling experiments four times, the CoOx/h-S-1-H used has almost the same chemical state and the same distribution of Co(II) species as the fresh catalysts. Based on DFT calculations and inhibition experiments, the oxidative coupling of thiols undergoes a free radical mechanism in which Co(III) causes RS-H cleavage into RS· and H· species. Subsequently, two RS· radicals are coupled to disulfides, while H· radicals react with the O species to form H2O molecules. This work not only provides guidance on catalyst design and parameter optimization for oxidative thiol coupling but also advances the understanding of the aerobic oxidation mechanism.

Knowledge about medicinal plants held by the inhabitants and traditional practitioners of the village of Mazateupa, Nacajuca, Tabasco, Mexico

The application of herbs for natural healing requires limitless wisdom, discernment and understanding of the natural order of the universe. The good use of our natural resources could solve economic, health and cultural problems, as they are one of the most felt needs in the communities of Mexico and Tabasco. In this sense, the main interest of this research is to analyze the traditional knowledge of the medicinal flora in Mazateupa, Tabasco.

Six people were interviewed in the community and 122 species were recorded. Fifty-two percent are herbs. On the other hand, 100 conditions were recorded, however, ten are the most common. There are many conditions that can be treated with different plants, although they are often used alone. There are many conditions that can be treated with different plants, although they are often used alone. Most of the plants, although medicinal, are also used as ornamental plants. This concludes that in the village of Mazateupa, traditional medicine persists.

The influence of macroeconomics, banking performance, investment and international trade on public welfare with economic growth variables as intervening variables in G-20 countries

Social welfare can be interpreted as a condition that shows a state of community life that can be seen from the standard of living of the community while what is meant by social welfare is a state of fulfillment of basic needs that can be seen from a decent house, the fulfillment of clothing and food, education, and health, or it can also be said that social welfare is a state in which a person is able to maximize his utility at a certain budget limit level and a condition in which physical and spiritual needs are met. The G-20 was formed because the international community was disappointed with the failure of the Group of Seven (G7) to find solutions to the global economic problems faced at that time . The need to improve banking performance, as well as increase capital with an adequate level of capital because it has a positive effect on Economic Growth but does not significantly have a positive effect on Social Welfare. And foreign direct investment (FDI) needs to be encouraged by G-20 countries to increase FDI so that it can provide new resources and technology, encourage economic growth because it has a positive effect, Investment does not significantly have a positive effect on improving social welfare. The international trade variable, measured by goods exports (X₄) and economic growth, measured by GDP growth (Y1) have a significant influence on GDP per capita growth (Y2) as an indicator of Public Welfare in G20 countries. This shows that increasing exports of goods can drive economic growth and public welfare in G20 countries. Through a deeper understanding of the factors that influence public welfare in G20 countries, more effective economic policies can be designed and implemented.

The Effects of Taxes on Income Distribution Justice

One of the most important economic problems that countries have faced from the past to the present is income inequality. Income distribution is an important indicator that allows us to understand the social and political structures of societies by revealing how the income gap between the rich and the poor in a country changes. Thus, income redistribution or income justice is one of the important goals of fiscal policy. Taxes are also important intervention tools that economic management has in achieving this goal. In this context, this study aims to examine the relationships between different types of taxes and income distribution in the Turkish economy during the period from 2002 to 2022 by using markov regime switching analysis method. The analysis results indicate that, during the period covered by the study, indirect taxes have a positive effect on income distribution, while taxes based on declaration have a detrimental effect on income distribution.

Use of sea wave containment techniques

This work makes a comparison between different wave control methods applied in coastal cities, using a small-scale experimental model. The coastal zone of Brazil extends over a considerable area and covers a significant portion of the national territory. It is common to find a variety of constructions on the seashore, from large buildings to small kiosks, many of which are irregular, as they do not follow the proper authorizations from the competent authorities, resulting in environmental, social and economic problems. The coastal environment is dynamic, subject to constant changes in its configuration, since the waves transport and deposit sand, even in small quantities. However, human activity has accelerated this process, although it is natural. Therefore, some methods have been developed to mitigate it.

An Introduction to Lagrange Multipliers: Theory and Applications in Economics

The purpose of this paper is to explore the basic applications of the Lagrange multiplier method in economics and to help beginners build their understanding of this mathematical tool. Tesla Inc. is used as a case study to examine how it maximizes profits by optimizing pricing and marketing expenses under given market conditions and constraints. The context of the study includes the importance of maintaining Tesla’s leadership position as the world’s leading electric car manufacturer in a competitive market. In this paper, the Lagrange multiplier method is used to incorporate specific market share and marketing expense constraints into the profit function and to find the extreme values by constructing the Lagrange function and solving for the derivatives. However, the results of the study show that the solutions obtained are extreme minima rather than the expected maxima. This result highlights the possible limitations of the Lagrange multiplier method in economic optimization problems. Nonetheless, this paper provides valuable lessons for understanding and applying the Lagrange multiplier method and points the way for further research on the application of optimization methods in economic decision making.

Co-planning as a public health tool: the Milan Health Protection Agencies’s Local Gambling Plan

Abstract Issue/problem Gambling represents a public health, social, and economic problem. Lombardy Region, according with national and regional law, has approved the Regional Plan for the prevention and contrast of Pathological Gambling. The Health Protection Agencies (HPA) of the Metropolitan City of Milan, as the other HPAs, implemented the Local Gambling Plan, based on a context analysis and in synergy with all the actors involved. Description of the problem Since 2019, the Milan HPA’s Local Gambling Plan has been implemented through collaboration with non-profit entities (TSEs), which are involved via public tendering. The implementation of the new Italian ‘Code of the Third Sector’ changed the TSEs engagement modalities. For this reason, a complex co-planning process has been initiated in order to increase the level of active citizenship and to enhance public health, in line with horizontal subsidiarity principle. Results The Co-planning procedure promoted the integration among local health services, non-profit entities and municipalities with the aim of gambling prevention and contrast, ensuring the continuity of prevention programs and the involvement of local stakeholders in addressing a public health issue. During the co-planning, 9 working groups were established to define objectives, project actions, monitoring and evaluation methods, ensuring the common interest of all actors involved. Lessons For the health and social system, the co-planning procedure becomes an opportunity to translate what is foreseen by the regulations into local actions. It allow the active participation of local stakeholders involved into the co-construction and achievement of public health objectives and the promotion of communities’ empowerment. Key messages • Co-planning is both a process and a tool for local welfare. • Co-planning involved multiple actors, among which the public institution that ensures satisfaction of health needs through governance actions.

The exploitation of silver deposits in early medieval Europe: some documentary, economic and social problems

AbstractFocusing on Southern Europe, this article sheds light on the mining landscape of the early Middle Ages. Based on the current state of historical and archaeological knowledge, the article raises a number of questions that can be extended to other European regions. The documentary problem shows that the scarcity of sources is due to a less developed mining historiography of the early Middle Ages. The few references show that it was not a question of ignorance, nor of the terrain, nor of the potential, nor of the techniques, taking into account the work in Melle and in the Harz. The study of production from the angle of an economic problem forms the basis of a hypotheses for selective and centralized exploitation during the Carolingian period and of an unbridled mining boom from the early 11th century. Even with the current paucity of documentary evidence, it is reasonable to assume that early medieval societies did not choose to exploit all the resources available to them. Finally, there is the social question. Who was behind the work and trade in ingots? The model of elite dirigisme will be discussed and it will be suggested that the role of the elite be reduced in favour of other actors such as entrepreneurs. Finally, the article argues for the extension of archaeological research to production areas in order to date operations, establish reference systems for ores and read archaeological remains from a social perspective.

Smoking, alcohol, substance, technology, and gambling addiction among university students

Abstract Background University students turn to addictive substances to cope with the anxiety and stress caused by separation from family, adaptation to a new environment, as well as many economic and social problems. This study aimed to examine smoking, alcohol, substance, technology, and gambling addiction among university students. Methods The data of this cross-sectional study were collected between February and March 2024. The study population consisted of 23,446 people studying at Ä°nonu University, and the sample size was calculated as 346 based on a smoking rate of 35.6% among university students. A stratified sampling method was adopted according to the faculty of study, and 366 people were approached regarding the study. The independent variables were age, gender, faculty of study, and smoking status, while the dependent variables were alcohol and substance use status. Descriptive data were expressed in numbers and percentages, and a Chi-square test was used in the statistical analysis. Results Of the students in the research group, 56.8% were female, 54.4% were 22 years of age or older, 30.1% reported smoking cigarettes, 7.7% reported drinking alcohol in the last 30 days, 39.2% reported using the internet for five hours or more per day, 3% reported playing various casino games on the internet once a week or more, and 1.4% stated that they used substances. There was no statistically significant difference between alcohol and substance use according to smoking status (p > 0.05). Conclusions Approximately one-third of the students in the research group reported smoking cigarettes, and one-tenth reported alcohol use, which is quite high. The high percentage of students who use the internet for five hours or more per day and the low rate of online gambling should be considered in relation to these addictions. Key messages • Multidimensional interventions and intersectoral cooperation are required to prevent smoking, alcohol, substance use, technology, and gambling addictions among university students. • In addition, precautions should be taken to protect students against the risks associated with internet addiction and online gaming.

Predicting the Duration of Forest Fires Using Machine Learning Methods

For thousands of years forest fires played the role of a regulator in the ecosystem. Forest fires contributed to the ecological balance by destroying old and diseased plant material; but in the modern era fires are a major problem that tests the endurance not only of government agencies around the world, but also have an effect on climate change. Forest fires have become more intense, more destructive, and more deadly; these are known as megafires. They can cause major economic and ecological problems, especially in the summer months (dry season). However, humanity has developed a tool that can predict fire events, to detect them in time, but also to predict their duration. This tool is artificial intelligence, specifically, machine learning, which is one part of AI. Consequently, this paper briefly mentions several methods of machine learning as used in predicting forest fires and in early detection, submitting an overall review of current models. Our main overall objective is to venture into a new field: predicting the duration of ongoing forest fires. Our contribution offers a new way to manage forest fires, using accessible open data, available from the Hellenic Fire Service. In particular, we imported over 72,000 data from a 10-year period (2014–2023) using machine learning techniques. The experimental and validation results are more than encouraging, with Random Forest achieving the lowest value for the error range (8–13%), meaning it was 87–92% accurate on the prediction of forest fire duration. Finally, some future directions in which to extend this research are presented.

Pattern of Drowning among Autopsies Conducted at Baroda Medical College and S.S.G Hospital

Drowning kills at least 3,72,000 people every year and is the 3rd leading cause of unintentional deaths. In addition to the human tragedy, drowning represents a huge economic problem with direct and indirect costs, including many Disability-Adjusted Life Years. In India, there is limited knowledge about the epidemiology of drowning.The objective of the study was to study the incidence, manner and epidemiology of deaths due to drowning in and around Vadodara region.The present study was conducted from May 2022 to April 2023 in Government Medical College, Baroda on 82 cases to study the various epidemiological parameters of drowning. In this study period, 1989 cases of post-mortem examination were done out of which 82 cases were of drowning deaths. A maximum number of cases were seen in the age group of 21–30 years with 43% cases of males, dominating the study population. 62% of deaths were accidental in nature and occurred during the rainy season. The most common place of occurrence of drowning was river (38%) followed by water canal (31%). Soddening of hands and feet was the most common external feature of drowning followed by the presence of froth at mouth and nostril. Drowning is a most ignored public hazard worldwide with serious implications for the society. Public awareness regarding safety measures and drowning prevention strategies suitable to the needs of geographical region should be adapted.

The purpose of this study is to determine the factors that cause anxiety based on their experiences. The exploratory qualitative research method was used in this study to reveal the experiences of adolescents who have excessive anxiety. The results of the study showed that adolescents have various perceptions about the factors that cause anxiety in themselves, including; 1) Loss, 2) Thinking too much about something, 3) Broken family, 4) Verbal bullying, 5) Trauma, 6) Failure to do something, 7) Economic problems in the family and 8) Too sensitive.

Food waste in Polish households as an economic problem

The aim of our research was to investigate the scale and causes of food waste in households and its economic consequences, as well as the respondents’ attempts to curb food waste. Empirical research was performed in 2023 in the form of a diagnostic survey employing a standardised questionnaire on a total of 802 subjects. It was found that most frequently wasted food included ready meals, bread, vegetables and fruit. Exceeding the expiration date, food spoilage, and preparing excessive amounts of food were the most common reasons for wasting food. To limit food waste, the respondents used measures such as freezing food to eat later, drawing up a shopping list, using food to prepare other meals, checking the expiration date and purchasing less food. It was also found that during the constant rise in food prices in 2022, the respondents used these measures more often than before. A large-scale information campaign is required to raise awareness of the necessity of preventing food waste.

Invasive Seaweed Rugulopteryx okamurae: A Potential Source of Bioactive Compounds with Antioxidant Activity

Rugulopteryx okamurae (RO) is a species of brown seaweed that has invaded several shorelines worldwide, including the Spanish Mediterranean and the Strait of Gibraltar coasts, causing serious environmental and economic problems. This work aimed to characterize the bioactive composition of RO. A high content of carbohydrates (58.7 ± 2.6 wt%), fats (17.1 ± 0.4 wt%), and ashes (14.3 ± 0.2 wt%) were found, together with lower protein content (5.5 ± 1.8 wt%). Holocellulose was the most abundant polysaccharide fraction (49.2 ± 1.3 wt%), showing 43.4 ± 2.0 wt% of cellulose and 5.8 ± 0.7 wt% of hemicellulose, followed by lignin (18.9 ± 2.5 wt%). The monosaccharides composition showed a high level of glucose (13.2 ± 1 wt%) and glucuronic acid (9.3 ± 0.5 wt%). RO contained high levels of essential nutrients (Ca, K, Na, S, Mg), trace minerals (Mn, Mo, Se, and Cu), and some toxic heavy metals (Ni, Cd, As). The main fatty acid present in RO was palmitic acid (C16:0, 30.8 ± 3.0 mg/100 g), followed by myristic acid (C14:0, 19.3 ± 2.4 mg/100 g) and eicosatetraenoic acid (C20:4, 19.2 ± 1.3 mg/100 g). The extract obtained by microwave-assisted extraction (MAE) presented significant contents of polyphenols (2.7 ± 0.2 mg GAE/g) and antioxidant activity (3.0 ± 0.4 mg TE/g DPPH, 4.5 ± 0.3 mg TE/g ABTS, 4.7 ± 0.3 mg TE/g FRAP). Six main polyphenols were identified by HPLC-MS/MS, showing higher contents of gallic acid (20.7 ± 1.5 mg/g) and chlorogenic acid (9.7 ± 0.5 mg/g). These results highlight the possibilities offered in the valorization of RO to obtain bioactive compounds with antioxidant performance in several applications.

Data-driven stochastic dynamic economic dispatch for combined heat and power systems using particle swarm optimization

In modern power systems, the uncertain behavior of renewable energy sources (RESs) may result in deviations from the optimal operating dispatches for the various power sources. The electric power generation from Combined Heat and Power (CHP) units is characterized by high efficiency with less pollution. To use CHP units more efficiently, the dynamic economic dispatch problem is applied to obtain the optimal power and heat sources’ outputs to satisfy heat and power demands while meeting the different operational constraints. In this paper, data-driven stochastic optimization is used to model these uncertainties utilizing the Generative Adversarial Networks in scenario generation that are accurate and do not require fitting models or modeling probability distributions. Then, the Fast Forward Selection technique is used to decrease the number of scenarios to improve system tractability. The results obtained indicate that the variability in electrical load, photovoltaic (PV), and wind turbine (WT) output significantly impacts the overall operational costs of the power system. Therefore, it is essential to incorporate the uncertainties associated with electrical load, PV, and WT when aiming for accurate results in economic dispatch. the study found that the overall operation cost of the dynamic economic dispatch of the electrical system for 24 hours after integrating RES achieved a daily savings of 2.5 % in the first scenario. Furthermore, the findings demonstrate that RESs positively contribute to reducing the total operational costs of the power system. The economic dispatch of CHP systems is influenced by the integration of RESs and the uncertainties associated with electrical parameters.

Sustainable development awareness and integration in higher education: a comparative analysis of universities in Central Asia, South Caucasus and the EU

Education for sustainable development in universities is shaping the agenda in this area, demanding continuous improvement in quality. There is a trend towards integrating sustainability issues and the implementation of sustainable development goals into higher education. Universities responsible for educating SD professionals must teach knowledge and develop skills in line with the SDGs. However, there is insufficient attention to this in educational programs; more often it is implemented through disparate initiatives. The article presents research conducted in universities in the countries of Central Asia (Kazakhstan, Kyrgyzstan, Tajikistan, Uzbekistan), South Caucasus (Georgia, Armenia) and the European Union (Italy, Bulgaria, Poland). The awareness of students and teachers about the SDGs, the problems of implementing SD were assessed, and ways to solve these problems were analyzed. Countries were divided into clusters for comparative analysis. The results show that students generally have limited knowledge about the global sustainable development goals, while teachers have a higher level of awareness. The article examines the contribution of education to raising students' awareness in the countries studied and their attitudes towards integrating sustainability into the curriculum. The questionnaire showed that the educational intervention significantly influences students’ intention to engage in sustainability. Overall, students demonstrate positive attitudes towards incorporating sustainability issues into their education. The results of a study conducted in higher education institutions in Central Asia, South Caucasus and the European Union showed that students are generally unaware of the sustainable development goals, their information received through the Internet, media and university studies is insignificant, while teachers are better informed. Students and teachers expressed the greatest concern about environmental, social and economic problems. At the same time, students of engineering, technical and medical fields are more informed about the SDGs compared to pedagogical and socio-humanitarian fields. To increase awareness, universities are encouraged to integrate sustainability education into various disciplines, conduct seminars, round tables, promote student participation in projects and research, and promote international cooperation and knowledge sharing.

Detection of bacteria of the genus Salmonella in meat from north-western Croatia

Salmonellosis is one of the most common food-borne zoonoses, and the most common source of infection for humans is meat and meat products. In 2023, 1125 samples of portioned meat (chicken, pork, beef) were tested in butcher shops in five districts of northern Croatia. The samples were tested for the presence of bacteria of the genus Salmonella, which were isolated in 88 (7.82%) samples. Salmonella was isolated from 604 chicken meat samples in 69 (11.4%) samples, from 319 pork samples in 10 (3.1%) samples and from 202 beef samples in 9 (4.5%) samples. Serological typing identified S. Infantis in 60 (87%) isolates from chicken meat samples, S. Mbandaka in 6 (8.7%) and S. Enteritidis in 3 (4.3%) samples. In pork, S. Derby was identified in 2 (20%) isolates, S. Typhimurium, S. Typhimurium (monophasic), S. London and S. Rissen in one isolate each (10%). In beef, S. Bovismorbificans was detected in 5 (55.6%) and S. Muenster in one (11.1%) isolate. Salmonellosis can be an economic problem due to the damage it causes in intensive production, but also a significant public health challenge as it spreads into the environment through the consumption and handling of contaminated meat in slaughterhouses, food processing and retail facilities. The implementation of appropriate hygiene measures and good hygiene practices from farms and slaughterhouses to butchers could help to reduce the contamination of meat with bacteria of the genus Salmonella.

Gene Expression Analysis for Drought Tolerance in Early Stage of Potato Plant Development

Drought has increasingly affected the yield of Solanum tuberosum L. (potato) every year over the last decade, posing serious economic problems for the global agricultural industry. Therefore, it is important to research drought tolerance in plants and obtain more robust varieties of crops. The aim of the present work was to study the expression of drought-upregulated genes in drought-tolerant and drought-sensitive varieties of potato. Bioreactors were used to identify whether each variety was drought-tolerant or drought-sensitive; then, expression analysis was performed according to the morphological characteristics of the plantlets in two different media: Murashige and Skoog (MS) medium and MS medium with 20% PEG-6000 to simulate osmotic stress. Based on the quantitative parameters of six initial varieties, two varieties were selected (Gala and Aksor) for further gene expression analysis. The expression of genes commonly upregulated in drought (ER24, TAS14, DREB147315, PP2C, 102605413 and NF-YC4) was higher in the drought-tolerant variety than in the sensitive one. Therefore, the expression of these genes can be used to determine the drought tolerance of a potato variety in vitro in the early plant development stage. Moreover, comparative analysis showed that some of the targeted genes used to identify drought tolerance in this study are conserved across different plant species.
