Seasonal dynamics of indicators of mineral metabolism in horses in the conditions of the Leningrad region
Authors: Karpenko L. Yu. , Bakhta A. A. , Balykina A. B.
Published: October 2024

The article analyzes the seasonal dynamics of mineral metabolism indicators in adult horses kept in private stables in the Leningrad region. As a result of the research, knowledge of the concentration and dependence of indicators on the seasonality of the year was obtained. It is important to remember that macro- and microelements are not synthesized in the body, they come from food, water, and air. The degree of their assimilation depends on the state of the respiratory and digestive organs. The most difficult period for animals is winter, when there is a decrease in the resistance of the body as a whole due to poor climatic conditions and minimizing physical activity in the fresh air. All these are predisposing factors for the imbalance of indicators at the level of the whole organism.

It is established that in the autumn-winter period there is a decrease in indicators relative to the average annual digital values. Thus, there is a linear relationship between the concentration of calcium and phosphorus in blood serum – the minimum values are observed in winter and are 2.53±0.27 mmol/l and 1.76± 0.11 mmol/l, respectively. And the maximum values are typical for the autumn period and are 3.63±0.29 mmol/l for calcium and 2.33±0.12 mmol/l for phosphorus. Similar dynamics is observed in other indicators of the body's mineral metabolism. Thus, for trace elements such as copper, iron, protein-bound iodine, the minimum values were noted in the spring period. This can be explained by a decrease in the mineral components of the feed itself, as a result of long-term storage, resulting in changes in the chemical composition of vegetable feed with fat oxidation. Microelementoses and osteodystrophic processes are observed in animals. The autumn period is characterized by the highest concentrations of minerals in the blood serum of horses, on average by 8-12% compared with the average annual figures, This is explained by the fact that it was in the summer period that the greatest benefit was obtained from juicy plant substances of feed and proper exercise.

This knowledge is necessary to understand the processes occurring in the body of horses at different times of the year and the possibility of correcting mineral supplements based on the data obtained

A significant problem in the field of standardization in the monitoring of infectious animal diseases is the lack of a system of conventional symbols of veterinary significant objects used in geoinformation technologies, in particular in digital and electronic cartography. The object of the study is the conventional signs of veterinary significant objects, which in the context of display on digital maps can be defined as "non–scalable", marked with corresponding pictograms. A systematic approach has been applied as a methodological basis for the epizootological research method. The basic graphic format of the proposed SVG symbols is used – (Scalable Vector Graphics), which is a modern generally accepted vector format. This article presents the results of cartographic display of pictograms of one of the three sets of symbols for the database – veterinary facilities for various purposes – for which the method of selecting basic signs is used. An algorithm for fixing elements of symbols of veterinary significant objects in the vector format of the SVG geoinformation system with maximum use of free software and secure information technologies is presented. Images in SVG format can be directly represented in current GIS and converted to almost any vector and raster formats without loss of image quality. The algorithm for developing a system of symbols for veterinary significant objects will be used in the Draft of the preliminary national standard in the future.
Deposit of pathogenic microbial strains as a basis for biosafety
Authors: Prasolova O. V.
Published: October 2024

The spread of animal infections is a major biological threat given the large number of animals imported into the Russian Federation in recent years. The deposit of already studied strains, on the basis of which specific prophylactics are produced, is necessary to prevent biological threats and protect the population and the environment from the impact of dangerous biological factors. Formation, preservation and development of the national collection of pathogenic microorganisms is the main task of the state policy in the field of chemical and biological security in the part concerning resource provision of the national system of chemical and biological security. Studying the properties of microorganism strains, especially those included in the composition of animal medicines, is the key to the epizootic well-being of the region where these vaccines are used. When analysing the monitoring of the epizootic situation on the territory of the Russian Federation, it is possible to assume the effectiveness of the use of a medicinal product through phylogenetic analysis of the genotypes of vaccine strains and isolates isolated in the focus of infection. In this way, it is possible to identify the source of the disease, understand the origin of the pathogen at a certain time interval, and assess the risk of using a particular prophylactic agent. Detailed analysis of isolates in individual regions creates prospects for retrospective analysis and identification of epizootically significant microorganisms in order to assess the variability of their cultural and morphological properties, pathogenicity, as well as to study their resistance to environmental factors and disinfectants. Special attention should be paid to the possibility of validation of diagnostic test systems, which is impossible without the presence of a characterised strain of microorganism.

Published: October 2024

The aim of this study was to perform a preputiotomy with the formation of an artificial opening in a breeding bull to realize his reproductive potential. Scientific and production research was conducted in the spring of 2024. In a 3.5-year-old Holstein breeding bull, kept at a breeding station for keeping breeding bulls, acroposthitis and fibrous lesion of the penis in the area of the S-shaped bend were detected due to the developed infectious process caused by Pseudomonas aeruginosa. The resulting pathology prevented the penis from fully extending beyond the preputial sac when collecting sperm for an artificial vagina (the last sperm collection was performed on 02/07/2024). The operation performed consisted of the following stages: insertion of a thick-walled tube into the preputial sac for better orientation in the tissues; making a V-shaped incision of all layers of the prepuce near its fornix; excision of the prepuce section necessary for free removal of the penis when collecting sperm; formation of an artificial opening by connecting the parietal preputial layer to the skin with an interrupted suture. The postoperative period included daily monitoring of the animal's condition, antibiotic therapy (amoxicillin (0.15 g), three injections every 48 hours), and the use of non-steroidal anti-inflammatory drugs (meloxicam (0.002 g), 3 days). A month after the operation, sperm was collected (06.05.2024, three months later) and the presence of all unconditioned reflexes was noted. At the same time, the copulatory reflex was full, painless and ended in ejaculation. The obtained volume of sperm after two mountings was 2.5 ml, the concentration was 1.3x108, the activity was 8 points. Thus, preputiotomy is an effective method for surgical correction of lesions of the preputial sac and adhesions in the area of the S-shaped bend of the penis in breeding bulls.
Factors influencing the development and implementation of new entomoceutical drugs in veterinary medicine
Authors: Tokareva O. A. , Shakirov S. R.
Published: October 2024

Recently, the use of insects in various directions has been increasing, and the field of veterinary pharmacology has not become an exception. Biologically active substances from insects have become the object of increasingly intensive research, due to their unique properties, wide variety and potential in humane as well as veterinary medicine. Scientific research is published annually, which examines a variety of options for the use of chemical compounds of insects for therapeutic and preventive purposes. But despite this, there are no mass-produced drugs recognized by the consumer. The phenomenon in which the number of scientific studies is not proportional to the products sold can be considered a natural process when unprofitable projects are eliminated, but, compared with other studies of sources of medicinal raw materials, an incomparable percentage of insect products "does not reach" mass sales. The identified causes slowing the development of entomoceutics can partially identify the shortcomings of modern humane and veterinary pharmacology and expand general knowledge about the subtle moment of transition from the initial idea to the products being sold by the example of insect medicines. Neural networks can make a significant contribution to the development of veterinary entomoceutics, allowing to accelerate the process of developing new drugs from insects, improve the selection of effective therapy for specific patients, taking into account genetic predispositions on which the activity of the body's enzymatic systems depends, as well as the presence or absence of idiosyncratic reactions in animals, and optimize ways to predict the activity of substances in a particular organism. With proper research, description of methods for the isolation and purification of active substances, centralized regulation, the use of neural networks and the necessary financing, entomoceutics is able to fill the market with high-quality veterinary pharmacological preparations, which, with less financial and time costs, will not yield pharmacokinetic and pharmacodynamic properties to medicinal substances obtained in a traditional longer-term way, which will allow in a short time to withdraw veterinary medicine pharmacology to a new qualitative level.
Studying the tolerability of a drug based on Amoxicillin and Succinic acid on piglets
Authors: Tokareva O. A.
Published: October 2024

To date, an important task is the development of medicines based on antibiotics and excipients with an active effect. Such combinations, in turn, should enhance the susceptibility of microorganisms to chemotherapeutic agents [1]. The main purpose of our experiments was to study the tolerability of a drug based on amoxicillin and succinic acid on piglets in therapeutic and fivefold doses [5]. The tests were carried out at a pig breeding complex in the Leningrad region. All selected piglets of a large white breed were quarantined for seven days, after which they were admitted to the experiment. 60 healthy piglets, two months old with an average body weight of 25 kg, were divided into 3 groups: 2 experimental and 1 control group of 20 animals each. One of the experimental groups was administered the drug with feed at a dose of 0.0175 g per kg of body weight, the second at a fivefold increased dose of 0.0875 g per kg of body weight 1 time once for 10 days. Based on the data obtained to study the tolerability of a drug based on amoxicillin and succinic acid, we found that using it with food once, for 10 days in a therapeutic 0.0175 g and in a fivefold increased dose of 0.0875 g per kg of body weight did not have a pathological effect on the body of the piglets tested. During the experiment, all animals remained alive, the indicators of the control and experimental groups were within the reference range and did not significantly differ from each other. The results obtained confirm the safety of using the drug based on amoxicillin and succinic acid in the recommended dosage regimen.
Диспозиции молодежи в отношении виртуальных компонентов государственной молодежной политики
Authors: Цибуля Никита Александрович
Published: October 2024

В настоящее время сфера государственной молодежной политики претерпевает значительные изменения, связанные с процессом цифровизации, который затрагивает всех ее акторов, вызывая у них реакцию, далеко не всегда учитывающую специфику складывающейся гибридной реальности, порождающей как новые возможности, так и риски. Несмотря на происходящую трансформацию и необходимость ее осмысления, в научном дискурсе отсутствуют работы, посвященные изучению диспозиций различных групп молодежи в отношении цифровой трансформации, выявлению особенностей государственной молодежной политики в виртуальном пространстве, барьеров, возникающих в ходе работы с молодежью в цифровом обществе. Целью исследования, проведенного методом фокус-групп, участниками которых стали школьники, студенты и работающие молодые люди, является определение особенностей их позиций в отношении виртуальных компонентов государственной молодежной политики. Результаты показали, что отношение молодых людей к онлайн-проектам и программам в сфере государственной молодежной политики противоречиво. С одной стороны, они заинтересованы в получении информации о проектной деятельности в виртуальном пространстве и даже участии в ней, c другой – демонстрируемый интерес носит инертный характер и не подкрепляется самостоятельными действиями по его удовлетворению. Автором установлено, что причины пассивности связаны с низкой эффективностью системы информационного обеспечения государственной молодежной политики, а также с несоответствием существующих виртуальных проектов и программ реальным потребностям молодежи, которая все чаще при рассмотрении возможности участия в практиках государственной молодежной политики, реализуемых как в реальной жизни, так и в онлайн-пространстве, ориентируется на личную практическую выгоду, которая вступает в противоречие с преимущественно социетальными целями государственной молодежной политики.

Comprehensive Analysis of Twitter Sentiment Using Machine Learning Algorithms for Enhanced Sentiment Prediction
Authors: L. Sudha Rani
Published: October 2024

The principal aim of e-commerce systems is to improve the consumer experience, with customer input being essential to this objective. This study introduces an innovative method for analysing tweet data to enhance customer happiness. Key tweet features were retrieved to capture the sentiment expressed in customer tweets by utilising a combination of n-gram models and word embeddings. The features were subsequently employed to construct classification models utilising Support Vector Machines (SVM) and Artificial Neural Networks (ANN), both of which are frequently applied in sentiment analysis. A model based on Convolutional Neural Networks (CNN) was proposed to enhance the accuracy of classifying sentiment by categorizing tweets as either positive or negative. The study's results indicated that the CNN model surpassed both the SVM and ANN models, exhibiting more accuracy in sentiment classification of tweets. In addition to its precision, the CNN model offered significant insights into the interrelations among different tweet categories, enhancing comprehension of client mood and views. This extensive study underscores the need of understanding the complexities of customer feedback to improve e-commerce strategies and consumer delight as well as the efficiency of the CNN model for sentiment categorisation. By means of exact classification and analysis of sentiment in real-time twitter data, e-commerce systems may more successfully evaluate customer impressions and react dynamically to enhance their whole experience.
Development of Modified Random Waypoint Mobility Model of Routing Protocol for the Mobile ad-hoc Network
Authors: Margam Suthar
Published: October 2024

Mobility models are used to evaluate the network protocols of the ad hoc network using the simulation.  The random waypoint model is a model for mobility that is usually used for the performance evaluation of ad-hoc mobile networks. Mobile nodes have dynamic mobility in the ad hoc network, so the mobility model plays an important role to evaluate the protocol performance.
In this article, we developed modify random waypoint mobility (MRWM) model based on a random waypoint for the mobile ad hoc network. In this article, the comparative analysis of modifying random waypoint mobility and random waypoint model on the ad hoc On-Demand Distance Vector (AODV) routing protocol has been done for a large wireless ad hoc network (100 nodes) with the random mobile environment for the 1800s simulation time.  To enhance the confidence in the protocol widespread simulations were accomplished under heavy traffic (i.e. 80 nodes) conditions. The proposed model protocol has been investigated with the performance metrics: throughput; packet delivery ratio; packet dropping ratio; the end-to-end delay and normalized routing overhead. The obtained results revealed that the proposed modified random waypoint mobility model reduces the mobility as compared to the random waypoint mobility model and it is trace is more realistic.

Authors: Tushar Patil
Published: October 2024

In today's society, there are an increasing number of people whose health need regular health examinations. The other category consists of people who have died or are suffering from specific diseases, the consequences of which can occur unexpectedly and result in a grave health crisis. The idea is to provide constant remote monitoring of particular patient functions that are critical to their survival, as well as the necessary assistance. The sensing of essential data related to a person's health wherever they are can be transmitted into a technical centre where it will be reviewed and understood under remote monitoring. This concept's applicability has a lot of potential. This work considers non-invasive sensors for monitoring of some physiologic parameters, data transit and processing, archiving, and visualization in addition to the aforementioned groups. This methodology served as the foundation for subsequent applied research projects established in collaboration with hospitals.
Determinants of private entrepreneurship in Kinshasa healthcare in the Democratic Republic of Congo: a structural equation modelling approach
Authors: Nsubile Clement , Bukele Theophane , Badisanse Astrid
Published: October 2024

Background

Since the 1980s, the liberalisation of the healthcare sector, driven by structural adjustment policies promoted by the Bretton Woods Institutions, has resulted in a significant increase in private healthcare entrepreneurs. One of the primary goals of this shift was to enhance geographical access to healthcare. However, there have been no comprehensive studies analysing the determinants of local healthcare entrepreneurship development in the Democratic Republic of Congo (DRC). This study aims to evaluate the relationship between the health zone profile and the development of private healthcare service provision in the DRC.

Methods

This research employs a cross-sectional and analytical approach, using a quantitative methodology based on the Partial Least Squares Path Modeling (PLS-PM) technique. The focus was on measuring the relationship between variables associated with the health zone profile and the growth of private healthcare services. An econometric analysis was used to test and validate this relationship.

Results

The findings reveal a positive relationship between the profile of the health zone and the development of private health services in Kinshasa (coefficient of 0.720). The health zone profile is primarily influenced by the mortality rate (coefficient of 0.793), while the development of private healthcare entrepreneurship is most strongly reflected by the number of paramedical practices (coefficient of 0.293).

Conclusions

The study suggests that continuous training initiatives and efforts to reduce mortality are crucial for improving health zone management. Moreover, managing healthcare infrastructure effectively in response to growing urbanization, rather than merely increasing the number of health areas, is recommended for better health zone management in the DRC.

This article revisits the role of Bilateral Investment Treaties (BITs) in Foreign Direct Investment (FDI). It investigates, in particular, the institutional quality of the host countries, the number of cases brought for resolution, plus a more nuanced formulation of numbers of BITs, focusing on developing host countries.The analysis looks at more recent developments in BITs and incorporates economic freedom as a proxy of institutional quality of the host countries and considers the number of Investor-State Dispute Settlement (ISDS) in the BITs. We assume a non-linear relationship between BIT and FDI. Models are run using feasible generalized least squares (FGLS). Our new findings reveal that there is an optimum level of BITs in attracting FDI (higher and lower numbers do worse), constituting a re-appraisal of past analyses. Previous ISDS cases show a significant negative relationship with FDI. Economic Freedom has a strong positive and significant relationship with FDI/GDP, as previously found.

Published: October 2024

The purpose of the study was to examine the influence of Corporate Social Responsibility, Family Ownership, and Institutional Ownership on Tax Avoidance in manufacturing companies from 2019 to 2022. This study employs a form of quantitative research that utilizes secondary data extracted from financial reports and business sustainability reports. The study sample consists of 226 manufacturing companies that were listed on the Indonesian Stock Exchange during the period of 2019-2022. The samples were chosen using the purposive sampling technique, applied to a total of 176 data points collected from 44 company samples throughout a 4-year research period. The data analysis employed double regression analysis techniques to examine the relationship between corporate social responsibility, family ownership, institutional ownership, and tax avoidance. The research findings indicate that these factors have a considerable negative impact on tax avoidance. Therefore, if the corporation implements higher levels of corporate social responsibility, family ownership, and institutional ownership, it will effectively prevent any potential instances of tax avoidance

Distribution of the field mice Apodemus flavicollis and A. sylvaticus in Norway
Authors: Lura Harald , Langhelle Gunnar , Fredriksen Tore , Byrkjedal Ingvar
Published: October 2024

Examination of specimens of yellow-necked and wood mice in Norwegian museum collections showed that yellow-necked mice are confined to areas with a continental climate, east and northwest of the South Norwegian watershed. The range of wood mice overlapped extensively with that of yellow-necked mice, but contrary to yellow-necked, wood mice also inhabited the most oceanic parts of western and southernmost Norway. Wood mice seem more or less absent in the most continental areas, where yellow-necked mice have their stronghold. Both species are rare in the Trøndelag counties, north of the South Norwegian mountains, and they are absent further north. A discriminant function analysis described the occurrence of yellow-necked mice by low January mean temperatures, low annual precipitation, less productive vegetation zones, and high April temperatures, and wood mice by long growth season and low April temperatures. The analysis alters the Norwegian range maps for both species.
Habitat and area use by red fox Vulpes vulpes vixens in mid-Norway

Published: October 2024

During 1990 - 91, area and habitat use of three red fox Vulpes vulpes vixens were monitored by radiotelemetry in a mixed cultivated and coniferous forest in the county of Sør-Trøndelag, central Norway. When resting, the vixens occurred mostly in dense and mature spruce forest. In contrast, mixed forest and more open habitats also were visited during hunting. On average, the area used was 4.97 km2 (min. 2.03 km2 - max. 10.24 km2). We propose that individual difference in area use reflect differences in food supply, but breeding behaviour and the restricted mobility associated with it may also play a part.
Determination of mutagenic effectiveness and efficiency of gamma rays and EMS in Coriander
Authors: C. Sarada
Published: October 2024

Coriander is a dual purpose vegetable used as leaf as well as a spice, along with medicinal properties. Owing to its compound umbel and difficulty in crossing programme, mutation breeding is the available source to create variability. Mutagenesis is a well-recognized tool to expand genetic variability. The present investigation involves mutagenesis in coriander cv. Sindhu with physical (gamma rays) and chemical mutagens (EMS) and their combinations. The mutation frequency, mutagenic effectiveness and mutagenic efficiency were calculated for the gamma rays, EMS and their combination doses. In gamma rays, a drop in mutagenic effectiveness was observed at 10Kr followed by increase with higher concentration. Mutagenic effectiveness due to gamma rays, ranged from 6.5 to 8.51 due to EMS ranged from 42.09 to 49.55 and due to combination treatments ranged from 12.17 to 18.80 (5kr+0.2% EMS) in coriander variety, Sindhu. The mutagenic efficiency based on survival ranged from 1.78 to 4.0, injury ranged from 3.83 to 8.2, sterility ranged from 2.37 to 5.18 indicating differential response to different mutagens. The combination of gamma rays and EMS at lower and moderate doses expressed its worth to create higher mutation frequency by manifesting higher efficiency than the individual mutagens single-handed.

Published: October 2024

Teacher attrition presents a pressing issue for educational institutions, particularly in the new normal. This study delves into the lived experiences of teachers who faced attrition in a private school in Laguna, Philippines, aiming to understand the reasons behind their decision to leave the profession. Through a qualitative phenomenological approach, specifically, transcendental phenomenology, involving key informant interviews with seven former teachers, recurring themes were identified through thematic analysis. Three major themes emerged: (1) Balancing personal and professional realities, which encompasses managing commitments, coping with job demands, and addressing trauma and mental health challenges; (2) Resources and resilience, highlighting the importance of institutional support, compensation, recognition, and professional growth opportunities; (3) Decision dynamics in navigating attrition, involving personal factors, career aspirations, and reflections on the pandemic's impact. These findings underscore the complexity of challenges teachers face in the new normal. Addressing these challenges necessitates a holistic approach that supports teachers' well-being, provides necessary resources, and acknowledges the multifaceted factors influencing their decisions. By understanding and addressing these dynamics, educational institutions can work towards retaining skilled educators and fostering their growth amidst evolving challenges.

Does a business education make for better innovative managers? An empirical examination of CEOs’ business education, CEO duality and R&D investment intensity
Authors: Al-Dubai Shehabaddin Abdullah Abdulwadod
Published: October 2024

This study aims to explore how chief executive officers (CEOs) business education influences their company's investment in Research and Development (R&D) taking into account the moderating impact of CEO duality. Risks related to investment in research and development might have an impact on CEOs who are responsible for improving management effectiveness and company value. Insufficient education among executives can hinder effective oversight. Findings from analyzing data from 1632 firm-year observations from 2015 to 2020 of companies listed on the Shanghai and Shenzhen Stock Exchanges reveal that CEOs with dual roles tend to prioritize R&D investments and innovation. Additionally, CEOs without a Master of Business Administration (MBA) or executive MBA education (EMBA) exhibit a greater willingness to take risks leading to more innovation and spending on R&D. This research emphasizes the need to consider CEOs' demographics, board structures and governance mechanisms to promote innovation in companies.

The main objective of photovoltaic system controller is to reduce the price of the kWh compared to traditional fuel-based electricity. Thus, the improvement of simple and low – cost controllers is a major challenge. Perturb and Observe (P&O) is the commonly used algorithm in order to ensure the power maximization of the photovoltaic system, due to its simplicity and effectiveness. However, on the main drawbacks of that algorithm is the fixed step size of perturbation, due to working environmental changes, which require dynamic tuning of the controller parameter. In order to overcome the cited disadvantage, a new Takagi - Sugeno variable step P&O is proposed. Based on the real-time measurements of the solar radiation and temperature, the proposed fuzzy system schedules the appropriate step size based on human expertise. A zero order Takagi – Sugeno with singleton output is proposed. The fuzzification were carried out using triangular and trapezoidal membership functions. The centroid defuzzification method based 25 If -Then rules are adopted.  In order to verify the effectiveness of the improved P&O, three scenarios were used. The obtained results show the effectiveness of the proposed controller under shaded conditions and various temperatures.

Energy consumption in poultry farming systems has a direct impact on the thermoregulation of the chickens, the ventilation of the house, and the quality of the air to provide a suitable indoor environment for chicken health. This makes the poultry industry an energy-intensive sector, with gas and electricity as major expenses. Therefore, the integration of solar photovoltaic systems can enhance energy saving in poultry farming, and reduce the emission of greenhouse gases. Accordingly, this study conducts thermal analysis to predict heat losses in winter and heat gains in summer according to the method described in the Regulatory Technical Documents (DTR). Our industrial poultry farm is the BAYAT Complex located in the Wilaya of Ouargla. The results obtained show that the total heating power is about 117.67 kW for a livestock building of 120x14 m² area containing 16000 chickens, while the cooling power for the same building is 553.92 kW. In the case of heating, the greatest heat loss comes from losses by transmission, about 88%. In the case of cooling, the internal thermal contributions represent 81% of that which enters through the structure of the building, of which 40% are latent internal contributions while 41% are sensitive.
