The article presents an analysis of the environmental sustainability and stability of the territory of the Omsk region using GIS technologies. The structure of the land fund of the region is dominated by agricultural land and forest land (respectively 53.8% and 41.9% of the total area). The share of the lands of settlements is slightly less than 2%. Industrial and other special purpose lands, specially protected territories and facilities, water resources and reserves amount to 2.6% of the territory of the region. Omsk region is divided into four natural and agricultural zones, differing in the structure of land categories (steppe, southern forest-steppe, northern forest-steppe and northern). In the steppe zone, the largest share is occupied by agricultural land, in the northern zone – the lands of the forest fund. The natural features of the zones have left their mark on the agricultural development of the territory. When moving from the north to the south of the region, there is an increase in the development of land. In general, in the Omsk region, the land fund is characterized by a high degree of development (63.4%) and plowing (44.3%). The high ploughing of the steppe zone (reaches 90.7%) enhances the processes of soil degradation here and worsens the hydrological regime, reduces the ability of natural landscapes to self-regulation. The indicator of water availability in the region (characterizes the ecological stability of agricultural landscapes) varies from 0.3% in the southern forest-steppe to 7.7% in the northern forest-steppe. In the steppe natural and agricultural zone of the Omsk region, the territory is mainly with unstable and unstable landscapes, in the zone of the southern forest-steppe unstable and unstable territory, in the zone of the northern forest – steppe - conditionally stable and medium-stable, in the northern zone pronounced ecological stability and stability of landscapes. The southern part of the Omsk region, where the agricultural sector is more developed, is experiencing significant overload when using land.

To date, it is quite important to prevent antibacterial contamination, osteoconductivity and osteoinductivity of the processes of reparative regeneration of bone tissue with the help of coatings for implants, as well as a variety of pharmacological drugs administered systemically or pointwise into the fracture zone. This is necessary to prevent degenerative-dystrophic changes in the osteoarticular system (false joint, arthrosis, resorption, sequestration, slow consolidation, non-fusion, osteoporosis, reduced vascularization), acute and chronic infectious lesions, joint blockage, deformity of tubular bones and disability. This article reflects the studies of clinical and biochemical blood analysis of three groups of animals (dogs) using the developed biocomposite injected into the intramedullary canal with a simulated transverse fracture of the middle third of the radius diaphysis. The components of the composite are used as: a matrix that compensates for parts of the destroyed bone, accelerates the processes of renewal of structural parts of cells, tissues at various stages of organization, while it has a stimulating effect on leuko- and erythropoiesis, as well as the process of phagocytosis, bone formation, prompting osteoprogenitor cells to proliferate and differentiate into osteoblasts. Also, due to the presence of a semi-synthetic broad-spectrum antibiotic (penicillin series), it has a bactericidal effect as a result of inhibition of bacterial cell wall synthesis. It is also worth noting that the developed composite is safely absorbed and biointegrated without reaction to a foreign body. Based on the conducted studies, a group of authors, taking into account the clinical and biochemical analysis, confirmed the absence of inflammatory, allergic, aplastic, hepatotoxic and nephrotoxic reactions from the macro- and micro-organism of animals.

The article presents the results of studies on the morphology, structure and chemical composition of chromium electroplating obtained by co-deposition with nanoscale aluminum oxide particles. Nanoscale particles were obtained by plasma recondensation of the feedstock. Electroplated chromium coatings were applied from a self-regulating chromium plating electrolyte in solid chrome plating modes with constant exposure to ultrasound on the electrolyte. The morphology and structure of the surfaces of the obtained coatings were studied using a Mira II Tescan scanning electron microscope. As a result of the conducted research, it was found that the introduction of nanoscale aluminum oxide particles into the chromium plating electrolyte leads to a decrease in the grain size of the coating, which entails an increase in the dislocation density and, as a consequence, the microhardness of the resulting coating. The average grain size of the chromium base coating was 1.1 × 10-4 cm, which corresponded to a dislocation density of 2.5 × 108 cm-2 and a microhardness of 9.6 GPa, while the nanocomposite electrolytic coating based on chromium had an average grain size of 7.2 × 10-5 cm, which corresponded to a dislocation density of 5.7 × 108 and a microhardness of 14.32 GPa. The analysis of spectrograms obtained as a result of emission analysis of samples with coatings showed that the nanocomposition electroplating of chromium contains elements of nanoscale particles used to produce it, which are absent in the base coating. This indicates the introduction of nanoscale particles into the coating during its application. The obtained results create prerequisites for further research and development of an algorithm and methodology for controlling the physico-mechanical properties of the coatings obtained by introducing a given number of certain nanoscale particles into them.

Wound pathology is one of the most important problems of modern veterinary surgery. Violation of connective tissue metabolism significantly affects the occurrence and development of many pathological processes in various organs and tissues, but the indicators of connective tissue metabolism in purulent wounds in cats have not been studied enough. Therefore, their study will allow pathogenetically substantiate and improve the methods of treatment of purulent wounds in cats. In animals of the experimental group who were treated with methyluracil with miramistin with the addition of 1% hyaluronic acid and 1% trifuzol, an increase in the content of hexoses associated with proteins, hexoses of glycoproteins and sialic acids was recorded only during the period of inflammatory and degenerative changes. In the future, starting from the twelve days of the experiment, these indicators decreased to the initial level. In animals of the control group during treatment, the content of hexoses associated with proteins gradually decreased, but was higher than in cats of the experimental group due to an increase in the proportion of hexoses of glycosaminglicans. Also in the control group, the content of sialic acids remained high throughout the experiment. This trend indicates that the use of ointment with the addition of hyaluronic acid and trifuzol contributes to the normalization of the G-GAG / G-GP index, which is characteristic of a more intensive development of reparative processes. On the contrary, an increase in the healing time of a wound defect in animals of the control group was accompanied by a redistribution of hexose fractions towards an increase in the proportion of glycosaminglicans. These changes are due to the gradual depolymerization and restructuring of the main substance of the connective tissue in the phase of regeneration and proliferation of the wound process.
ORGANIZATIONAL AND ECONOMIC MEASURES FOR IMPROVEMENT OF TERRITORIAL AND SECTORAL DIVISION OF LABOR IN AGRO-INDUSTRIAL PRODUCTION
Authors:   Kuban State Agrarian University named after I. T. Trubilin, Polutina Tatiana Nikolaevna
Published: October 2024

Given the complexity of the current socio-economic situation in geostrategic territories, especially with the attraction of investments in agriculture, it is advisable to use measures that are quite feasible in practice, relatively low-cost and quickly recouped. First of all, they should include the improvement of the territorial-sectoral division of labor in agro-industrial production, which is the core of its development. In this complex and dynamic process, the state should play a key role, for which it is necessary to develop and implement in practice a strategy and scheme for the development and placement of agro-industrial production, on the basis of which it is advisable to form large-scale specialized zones for the production of certain types of agricultural products. It is necessary to develop a system of organizational and economic measures to improve the territorial and sectoral division of labor in agro-industrial production, linking it with the subprograms, directions and main activities of the State Program for the Development of Agriculture and regulation of agricultural products, raw materials and food markets. Its mandatory regulation is necessary, which should be carried out both by the state and directly by the participants of a particular product segment of the agro-food market. The main purpose of such regulation should be to facilitate the concentration of production of certain types of agricultural products primarily in the most favorable natural conditions and areas based on the use of the advantages of the territorial-sectoral division of labor in agro-industrial production. In modern conditions, almost no Russian region is able to independently meet the needs of its population with a full range of food, even according to the norms of rational nutrition, although many regions have a fairly high degree of specialization of production for certain types of agricultural products. The interregional exchange that has developed in recent years in the country is characterized by a huge branching and scale both in the import and export of grain and its processed products, meat and meat products, milk and dairy products, eggs, which reflects the close interconnectedness and interdependence of all Russian regions on the functioning of the national agri-food market and its product segments, which is evident from the example of interregional grain supplies, taking into account its import and export. Therefore, the more deeply developed the territorial-sectoral division of labor in agro-industrial production, the more important the role of cooperation and cooperation of disconnected economic entities and regions in the process of interregional commodity exchange, the establishment of long-term food ties.
MAIN DIRECTIONS OF DEVELOPMENT OF SMALL AGRICULTURAL BUSINESS
Authors:   Russian Academy of National Economy and Public Administration under the President of the Russian Federation, Generalova Svetlana Vladimirovna
Published: October 2024

The article discusses the socio-economic significance of small agricultural business as an economic institution in the national economy. It is noted that small forms of management in the field of agricultural production make a certain contribution to ensuring the country's food security, expanding the scale of competitive relations, and diversifying agricultural production. The main problems for the development of small agribusiness are identified, which include the following: insufficiently high level of investment in the fixed capital of small agricultural enterprises; lack of own financial resources, inaccessibility of borrowed funds; high import intensity of manufactured products; difficulties with storage, processing, sale of manufactured products; insufficiently developed infrastructure in rural areas. It is concluded that the solution of these problems is associated with the transformation of the state support model, which should include a system of effective measures, tools, methods and be carried out in the following directions: ensuring the effective modernization of labor tools in order to comply with their modern world technical and economic level, through the activation of the main tools investment policy in agriculture; ensuring the growth of production capacities through the organization of processing modules on the basis of functioning C (F) H and cooperatives; development of production based on the use of a system of crop rotation of high-margin crops; stimulating the development of agricultural marketing; stimulating the development of export-oriented small agricultural enterprises, which largely contribute to the diversification of production, the growth of the quality of manufactured products; improvement of road transport and logistics infrastructure in rural areas; activation of further processes of effective integration and cooperation; structural change in the forms of small agribusiness entities through the transformation of households into peasant (farmer) households.
SPATIAL ORGANIZATION OF DOMESTIC AGRICULTURE WITH INTEGRATION EAEU MEMBER STATES
Authors:   Federal Research Center for Agrarian Economics and Social Development of Rural Territories - All–Russian Research Institute of Agricultural Economics, Altukhov Anatoly Ivanovich
Published: October 2024

Spatial development of agriculture in Russia is a natural, but at the same time complex and diverse process of social division of labor, which is largely capable of ensuring the effective functioning of the economy of the industry of each region and country as a whole, reducing costs, improving the quality and competitiveness of its products. It has more real prerequisites for its development and will provide a more significant positive effect when the territorial and sectoral division of labor in agriculture is more clearly manifested, interregional exchange is expanding, cooperation and integration between individual regions of the country and the EAEU countries are strengthening. At the same time, rural territories, traditionally occupying huge areas of the country, being at the same time the habitat and vital activity of one quarter of its population, largely remain the guarantor of stable spatial development of the state, in which rural settlements act as its peculiar foundation, linking together economic centers with the periphery. In Russia, with its historically characteristic significant diversity of natural, territorial, social, economic, regional and many other conditions for agriculture, it is the spatial organization that traditionally actively influences its development, and of a twofold nature, being a strong acting impulse or, conversely, a constant brake and even an insurmountable obstacle. This is evidenced primarily by the domestic long-term experience, when the country, due to the mobilization of internal resources in a relatively short time, not only created large-scale specialized zones for the production of certain types of agricultural products and mastered huge deserted and remote territories for farming, but also relatively quickly lost its territorial advantages associated with rational placement, deepening specialization and the optimal concentration of agricultural production. The spatial development of agriculture in the country is an indistinctly expressed territorial organization of the industry with relatively poorly interconnected regional processes of placement, specialization and concentration of production of certain types of agricultural products aimed at increasing their volumes and reducing costs. The intensity of their development is mainly due to the demand for the products of the industry and its possible supply to the member countries of the Eurasian Economic Union, as well as the effectiveness of state support for agriculture and regulation of certain product segments of the domestic agro-food market.

The most important component of the development of the national economy is the effectiveness of innovative activities of organizations. This leads to the need to increase attention to specific indicators that determine the innovative activity of the organization. It is reasonable to attribute the innovative potential of the organization to such indicators. In the article, based on the principles of a systematic approach, issues related to the concept and constituent components of the organization's innovative potential are considered. It is proposed to consider the innovative potential as a system consisting of a set of interconnected and interacting innovative components of intellectual, informational, organizational, labor, production and technological, natural, material and technical, financial, infrastructural, market potentials aimed at creating a result that will be in demand by the consumer and increase competitive position of the organization. An analysis of the innovative development of Russia using the data of the global innovation index of the countries of the world over the past seven years shows that our country is significantly behind the world leaders and there are actually no significant changes in Russia's positions in the ranking, while there is a downward trend in the sub-index "innovation results" and, as a result, , to the deterioration of the coefficient "efficiency of innovation", which indicates a weak implementation of the existing innovation potential. The data of statistical information of Rosstat also show that the innovative potential is used to a limited extent in Russian practice. In addition, insufficient funds are allocated by the state and organizations for the development of innovative processes. The results of the analysis once again confirm the need for a comprehensive and balanced policy aimed at further accelerated development of Russia's innovation system. The competitive innovative advantages of Russia are mainly related to the quality of human potential, so the effective use of the huge intellectual potential can bring the country to a leading position. The article proposes measures to accelerate the introduction of creativity products into the economy and improve the existing conditions aimed at improving innovation activity in Russia.

The use of digital marketing creates marketing competition among MSME players. MSME players need to apply effective marketing techniques to win competition between business actors. MSME players who master copywriting techniques and attractive social media content will make the public aware of the existence of a product or brand, resulting in purchasing decisions. The research method used by researchers is a mix method, namely an approach to analyzing problems quantitatively and qualitatively. The results of this research show that copywriting hooks have no effect on brand awareness, but copywriting hooks have a significant positive effect on brand image and purchasing decisions. Instagram social media content has a significant positive effect on brand awareness, brand image and purchasing decisions. This shows that hook copywriting and social media content on the Instagram platform have an important role in marketing activities with the aim of improving consumer decision making regarding the products being marketed.
Observation and Prediction of Instability due to RD Fluid Force in Rotating Machinery by Operational Modal Analysis

Published: October 2024

In recent years, as rotating machinery has become smaller and more efficient, various types of shaft vibration problems have arisen. Failure of rotating machinery may lead to major accidents and infrastructure shutdowns. Therefore, to prevent failures of rotating machinery, there is a growing need for the vibration analysis technology at the design stage and condition monitoring during operation stage. One of causes of the shaft vibration problems in rotating machinery is the rotordynamic (RD) fluid force acting on fluid elements such as journal bearings, seals, turbine blades, and so on. RD fluid force has a significant effect on the stability of rotating machinery and can destabilize the system. In recent years, operational modal analysis (OMA) methods, which identify modal parameters based on the measured data of a machine's operational condition, have been investigated in the condition monitoring. In this paper, the estimation of the modal parameters of rotating machinery using OMA from only the time history response of displacement data and, in particular, the prediction of the destabilization of rotating machinery caused by RD fluid force are investigated. As a result, the modal parameters are well estimated and, in particular, the destabilization of one mode due to RD fluid force is predicted and explained. The results are in good agreement with the results of the eigenvalue analysis of the original system, and the method is validated. Furthermore, the proposed method is applied to experimental data of the system destabilized by fluid force. The change in stability with rotational speed is observed, and the characteristics of the mode toward destabilization are confirmed. The results show the validity of OMA's predictions of destabilization in the experiments.
Efficient Differential Diagnosis using Cost-aware Active Testing

Published: October 2024

The diagnosis of complex systems benefits greatly from a differential, multistep approach that narrows down the list of possible conditions or failures that share the same observable effects to a single root cause. We provide a suitable and practically applicable methodology for this. In extension to existing work, it covers all types of diagnostic actions, i.e., the observation of system properties, active testing, and system interventions like providing a dedicated diagnostic input or forcing the system into discriminating states, but also the replacement of components. Combining all these possible steps into one probabilistic and causal reasoning framework, we I) stepwise generate the diagnostic model systematically to correctly cover the interplay of observations and diagnostic interventions, and II) provide decision support based on counterfactuals for the selection of the next diagnostic step, countering the vast number of possible actions that arise in machine diagnostic processes, considering costs of actions to minimize the expected overall cost of the diagnosis.We developed and successfully tried our methodology for diagnosing cyber-physical systems in the high-tech industry, but we found that it supports more processes, such as computing intervention actions for autonomous robots.
Enhanced Method for Localization of Partial Discharges in Oil-Filled Transformers Using Acoustic Emission Signals
Authors: Otake Yasutomo , Tajiri Kunihiko
Published: October 2024

The accurate measurement of partial discharges (PD) in power transformers is a critical component in identifying faults and planning effective maintenance strategies. Acoustic emission (AE) sensing technology is suitable for detecting partial discharges in transformers because it is less affected by external electromagnetic interference and detects PD non-invasively. This paper delves into examining the relationship between the detection intensity, the specific type of PD source, and the distance to the discharge source, using AE sensors. It was observed that AE wave intensities from corona discharges tend to be relatively strong, indicating a higher detection probability. Creepage discharges usually exhibit the next level of intensity, followed by the PD occurring in bubbles. It is considered that the intensity of the AE waves varies significantly depending on both the speed at which the discharge propagates and the medium and volume of the discharge space. Furthermore, this study has conducted experimental comparisons among three distinct methods for calculating the Time Difference of Arrival (TDOA) in localization calculations. These methods are the energy criterion, Generalized Cross-Correlation (GCC), and GCC with Phase Transformation (PHAT). The experimental results suggest that the energy criterion method is particularly effective when sensors are distributed placement around the entire tank. In contrast, the GCC-PHAT method shows greater suitability in scenarios where sensors are centralized placement in certain sections of the tank. It was clearly observed that the GCC-PHAT method, which suppresses the impact of noise and reflections, consistently achieves higher estimation accuracy in comparison to the standard GCC method. Notably, this method has shown the ability to maintain its accuracy levels even in cases of low discharge intensities. The implications of these findings are significant, as they could improve the precision and effectiveness of maintenance diagnostics in power transformers.
Anomaly Sign Detection for Automatic Ticket Gates by the Histogram Limitation Method
Authors: Ueno Ken , Maya Shigeru , Endo Kiyoku
Published: October 2024

It is crucial to appropriately maintain automatic ticket gates (ATGs) to keep transportation operating smoothly in urban areas. Although the average failure rate of new ATGs is extremely low, continuous operation for many years might lead to unstable performance due to deterioration, and the need for periodic maintenance to avoid fatal faults might halt operations for extended periods. To detect anomalies at an early stage, “anomaly signs” can be utilized to flag ATGs for maintenance by service engineers before anomalies occur. In addition, to minimize the cost of ATG monitoring, the necessary computing resources should be minimized, which means using only light-weight statistical methods rather than deep learning or machine learning. In this paper, we focus on the automatic separation modules inside ATGs that separate multiple tickets by complicated mechatronic controls because this module is the major cause of maintenance calls from station attendants. We propose a simple anomaly sign detection, called the histogram limitation method (HLM). We evaluated the anomaly sign scores over time with maintenance timing and compared them with the conventional fast unsupervised anomaly detection method, Histogram-Based Outlier Score (HBOS) widely used in various domains. The experimental results using real field ATG monitoring data show that HLM successfully detected anomaly signs before a maintenance call was necessary, which is better performance compared with HBOS. Despite being a simple modification based on HBOS, HLM also provides anomaly sign scores that agree adequately with assessments by maintenance service engineers.

Published: October 2024

The increasing complexity of deep space missions introduces significant challenges in maintaining spacecraft health, particularly in the propulsion systems, due to the inherent communication delays with Earth. This research proposes a novel framework for the autonomous, data-driven fault diagnosis of spacecraft propulsion systems. Leveraging data generated from a spacecraft propulsion system simulation model. The study addresses the limitations imposed by computational resources and sensor installation constraints through Sequential Forward Selection (SFS) for optimized sensor placement and feature selection. The framework's effectiveness is demonstrated through implementation on a microcomputer, showing promising results in terms of diagnostic accuracy and processing speed, thus highlighting its potential for onboard spacecraft application. This study not only advances the autonomous capabilities of spacecraft in deep space but also contributes to the broader field of Prognostics and Health Management (PHM) by providing a scalable, efficient approach to fault diagnosis in critical spacecraft systems. The proposed framework demonstrates a promising approach to optimizing diagnostic tasks for spacecraft systems. However, the trade-offs observed necessitate a careful consideration of task-specific requirements and the potential need for adjustments to maintain a high level of accuracy alongside computational efficiency.
Univariate Measures of Persistence: A Comparative Analysis
Authors: Arango-Castillo Lenin , Martínez-Ramírez Francisco J. , Orraca María José
Published: October 2024

Persistence is the speed with which a time series returns to its mean after a shock. Although several measures of persistence have been proposed in the literature, when they are empirically applied, the different measures indicate incompatible messages, as they differ both in the level and the implied evolution of persistence. One plausible reason why persistence estimators may differ is the presence of data particularities such as trends, cycles, measurement errors, additive and temporary change outliers, and structural changes. To gauge the usefulness and robustness of different measures of persistence, we compare them in a univariate time series framework using Monte Carlo simulations. We consider nonparametric, semiparametric, and parametric time-domain and frequency-domain persistence estimators and investigate their performance under different anomalies found in practice. Our results indicate that the nonparametric method is, on average, less affected by the different types of time series anomalies analyzed in this work.
Perceptual Variables and Nascent Entrepreneurship in Selected Latin American Countries.
Authors: Landa Fournais Luis Enrique , Landa Lizarralde Sara María
Published: October 2024

Abstract
Purpose: Provide empirical evidence of the impact of perceptual variables and beliefs on a person's decision to join or not to join the group of nascent entrepreneurs.
Methodology: Logistic regression applied to the most recent data from nine Latin American countries available in the 2018 GEM survey. Following existing literature, we interconnect perceptual variables with control variables in the form of sociodemographic characteristics.
Results: New entrepreneurs tend to depend more on subjective perceptions than on sociodemographic variables. Evidence suggests that having the confidence of possessing the necessary knowledge and skills plus knowing a model entrepreneur are inseparable variables with the greatest impact on the decision to become an entrepreneur. Our results also suggest that entrepreneurial knowledge does not necessarily originate from formal classroom education, as this variable was found to be not significant in the model. This supports the hypothesis that confidence in one's knowledge and abilities result from the contact with other entrepreneurs who serve as role models, instructors and mentors, which is consistent with Social Learning Theory.

The study explores the individual, organizational, and technological barriers to knowledge sharing among university students in Libya, and whether any significant differences could be attributed to the influences of demographic factors. A questionnaire was developed, validated and used to collect the required data. The sample size was 384 as recommended by Krejcie & Morgan (1970), and a higher sample of 409 responses were with 399 deemed valid for the analysis phase. Statistical Package for Social Science (SPSS) was used to analyze the data. Reliability tests, normality tests, means, frequencies and hypotheses tests were all used at this stage. The key results of the study are that knowledge-sharing barriers negatively affect knowledge-sharing. The study has its limitations, especially the limited number of published studies on the topic in Libya. The recommendation and implications of the study are that decision-makers and the Libyan Ministry of Education and universities should be more aware of such a problem to take all necessary measures in this respect.

Financial literacy ensures that an individual is able to match his income with his expenditure, lives within his means and forestall going broke or bankrupt. Like general or health literacy, financial literacy could be conceptualized as having two dimensions: understanding (personal finance knowledge) and use (personal finance application). In this study, we reviewed how financial literacy is measured in the current literature and examine how well the existing studies addresses whether financial literacy improves employees savings culture and investment. We review the literature on alternative policies to improve financial outcomes and compare the evidence on whether financial literacy improves employees spending habits, savings, investments and standard of living. The sample size of this survey based study consists of 110 working men and women from non-financial public sector in Nigeria. Data was analyzed using simple percentage and frequency distribution. The Statistical Package for Social Sciences (SPSS) was used in the analysis of the data. The major challenge in financial education has been how to measure the impact of financial education on the recipient savings culture. Investment and standard of living. On the other hand what is the influence of financial literacy on employees’ savings and investment outcome. It can be observed that in some instances those who did not have formal financial education and those who are primary or secondary school dropout have risen to own successful business empire. However, some who have tertiary financial education are struggling to survive. A large proportion of the sampled employees are deficient in financial literacy notwithstanding their exposure to financial education. Contrary to popular perception this research shows that there is no significant relationship between financial literacy and education level, savings culture and investments, of Nigerian public sector employees. Finally, we discuss directions ........

As global public health continues to face evolving challenges, developing effective and safe vaccines has become increasingly crucial, with the design of epitope-based vaccines representing a significant breakthrough in the field. The design of epitope vaccines generally involves utilizing immunoinformatics tools and techniques to analyze known or newly identified amino acid sequences, allowing for pre-selecting and identifying potential dominant epitopes. Subsequently, peptide vaccines containing these epitopes are synthesized through chemical or genetic engineering. The rapid progress in Immunoinformatics has greatly expanded its application in vaccinology, making it the most efficient approach for developing epitope-based peptide vaccines. The review outlines the general workflow of Immunoinformatics in the design and validation of epitope vaccines, highlights the key Immunoinformatics tools used in epitope vaccine development, and discusses the specific applications of Immunoinformatics in epitope vaccine design. These insights aim to provide valuable references for the rational design and development of potent epitope vaccines.

Arterial grafts have higher patency rates when compared to venous grafts. Total arterial revascularisation is commonly being done nowadays and more commonly in young patients and also in patients with poor quality veins, amputated patients, patients with DVT, post burns patients in whom veins are thrombosed and in patients with non healing ulcers and infection over the legs. A variety of configurations can be made using total arterial revascularisation, using bilateral internal mammary arteries or LIMA-RIMA-Y graft or using internal mammary arteries along with radial artery.
Preferences of Subterranean Termites (Coptotermes sp) for Monocotyledonous Plants and Dicotyledonous Plants on Mineral Land

Subterranean termites are recognized for their capacity to damage various plant species, regardless of their productivity. These termites can launch attacks with varying degrees of intensity, targeting both trees and living plants, particularly in agricultural settings such as oil palm and rubber plantations, as well as in industrial forests comprising species like pine and eucalyptus. Characterized by its tropical climate, Indonesia exhibits high levels of environmental humidity, warmth, and organic matter in the soil, which further supports termite activity in a study conducted in the Tj. Keliling Village Plantation area of Salapian District, Langkat Regency, ten bait woods were randomly planted in a rectangular plot measuring 12 meters in length and 7 meters in width. The spacing between the rows of bait wood was set at 30 cm, while the distance between individual bait wood columns was 60 cm. A descriptive method was employed for data analysis. The findings revealed varying percentages of damage among different types of bait wood: 10% for Pinang wood, 5% for coconut wood, 18.3% for oil palm wood, 33.3% for durian wood, 73.3% for teak wood, and the highest damage percentage of 77.3% for kapok wood. The attraction of termites to plants situated on mineral soil is attributed to the latter's role in enhancing humidity, which is a critical factor facilitating the rapid growth and proliferation of subterranean termites. Consequently, the intensity of their attacks can occur at any time until appropriate management measures are implemented.
