A Review of Graduate Attributes in the Oman Authority for Academic Accreditation and Quality Assurance of Education (OAAAQAE’s) Quality Audit Reports
Authors: Talib Al-Saadi Zulaikha
Published: July 2023

With the growing importance of the development of graduate attributes (GAs) in higher education, higher education institutions (HEIs) are emphasizing which GAs their graduates attain as part of their mission, vision, and core values, and are required to describe and document how their programs contribute to the development and promotion of those attributes. Qualitative data were collected from 12 quality audit reports from the Oman Authority for Academic Accreditation and Quality Assurance of Education (OAAAQA). This paper identifies the OAAAQA’s key areas of interest and their importance in ensuring quality in college-preparedness programs, as well as making recommendations for future audits. The paper seeks to: (1) highlight the most salient issues that have been raised in their reports regarding GAs and (2) make some suggestions so that HEIs in Oman can establish and implement GAs more effectively to meet both the OAAAQA’s expectations and good international practices. Following a data-driven systematic qualitative content analysis (QCA) of the QA reports, four main categories emerged regarding the GAs. Student learning objectives should be aligned with GA development, while stakeholders’ awareness of these attributes should be raised. Additionally, there is a need for an appropriate evaluation mechanism for GAs to be conducted in a systematic and timely manner. Moreover, GAs should be explicitly assessed and benchmarked based on the feedback obtained from relevant stakeholders. Finally, both internal and external stakeholders should be involved in the GA development and review process.
The Ability of Law to be Abstract and Specific as Its Most Important Functional Characteristics

The article analyses the objectively existing problem of law as an impossibility to achieve the full harmony between abstractness and concreteness of normative precepts. The author notes that concreteness is as necessary to law as its inherent abstractness. Excessive abstractness leads to a waste of the law’s relationship with the relations being regulated. On the other hand, it is excessively casual and tends to undermine the very foundations of law, which a priori does not allow for individuality in the rules of law. The author sees a certain way out of this predicament in the specialisation of legislation. The special rules, possessing a certain and unavoidable abstractness, at the same time by its very nature have a specifying effect.

The article is devoted to the consideration of the problem of the functioning of law in the cultural and historical aspect. Attention is focused on the fact that the problem posed has not only theoretical, but also practical significance. Using the example of an appeal to the materials of the VIII Parliamentary Forum «Historical and Cultural Heritage of Russia», where the issues of preserving and multiplying the components of Russian cultural achievements were discussed, it is emphasized that in the course of preserving the historical and cultural heritage of Russia, it is possible to form a national idea. Moreover, lawyers should play an important role in this work, relying on the cultural, historical and other functions of law to provide legal support for this noble activity.

At the turn of the XIX–XX centuries, the problem of the functions of law becomes the subject of stable scientific interest of representatives of Russian sociological jurisprudence. By the function of law, the authors understand both the social purpose of law and the direction of legal influence on the relevant sphere of public relations. Distinguishing between the functions of common law, sectoral rules of law and norms of law, scientists lay the foundations for their future classification. A fundamental role in determining the proper legal functions of law is played by the legal understanding of the authors, according to which priority is given to the function of either protective or regulatory. During the interpretation of social functions (economic, political and educational), theoretical disagreements lose their significance, giving way to liberal ideology.
Evolution of the Religious Function in Roman Law
Authors:   Professor of the Department of State and Legal Disciplines of the Smolensk State University, Doctor of History, Professor, Kazakov Mikhail M.
Published: July 2023

At all stages of history, an important role in the sphere of social relations was played by religion, which also acted as the most important factor in the interaction between society and the state. Although religion can be considered as an independent legal system, such as Sharia, and in the general form of religious law, in the concept of law, the religious function, it seems, should be highlighted in particular in view of the fact that it plays an independent role in the entire legal system and develops in a special way. The purpose of the article is to show the evolution of the religious function in Roman law, which underlies many modern legal systems. The sacred function was the main one at the beginning of the formation of Roman law, and then more features that were secular began to appear in it. However, the transition to the Empire led to the fact that the religious function was firmly entrenched in Roman public law, and during the period of Christianization of the 4th century, this function assumed consolidation in laws the formulas of faith binding on all the subjects.

Marginalism is a doctrine in economics that applies methods of analysis based on operating with ‘marginal’, that is, incremental values. Evaluation is carried out in terms of the impact that a change in a certain value has on the level of utility or other significant category. In the 1870s, a ‘marginal revolution’ took place in economics. A little later, a marginal revolution is also taking place in legal theory. Deterrence from committing crimes becomes the main goal of bringing to legal liability. Punishment (legal liability) is necessary only to stop the lawful behavior, despite the fact that it is to be assessed how a change in the measure of liability by a certain amount affects the change in the level of illegal behavior. O.W. Holmes jr., especially in the works ‘The Common Law’ and ‘The Path of the Law’, begins to use marginal values for the analysis of law. With this in mind, this article analyzes the marginalist aspect of O.W. Holmes’ legal thought.

The article presents the results of research on the empathy of policemen, rescuers, doctors and psychologists, as the best representatives among helpers. It also describes the qualitative and quantitative changes in the levels of empathy among these specialists after the implementation of a comprehensive socio-psychological program.
The goal is the approval of a complex socio-psychological program for the formation of professional empathy among specialists in helping professions, in particular, police officers, rescuers, doctors and psychologists. To conduct the research, the following methods were used: psychodiagnostic technique “Diagnostics of the empathic abilities level” by V. Boiko, content analysis, and Wilcoxon t-criteria to determine statistically significant shifts.
The results. On the basis of the conducted research, it was established that empathy undergoes positive changes under the influence of the proposed comprehensive social-psychological program. As we can see the t-Wilcoxon results showed statistically significant shifts at the p<0.01 and p<0.001 levels. Positive changes occurred among representatives of all studied professions, however, the highest rates of change were found among psychologists and police officers.
Conclusions. Theoretical analysis shows that empathy is mostly considered as an emotional component of the personality, which often appears in a negative way for specialists of some professions. However, the empathy of rescuers, police officers, doctors and psychologists manifests itself through a behavioral component and contributes to the emergence of empathic actions. Therefore, the positive results of the implementation of a complex socio-psychological program allow us to insist on the effectiveness and feasibility of its application for other specialists in the field of helping professions.

Authors: Samara Olga , Voitsekhovska Oksana , Stavytska Svitlana , Shelenkova Nataliia , Mateiko Nataliia , Moskalets Viktor
Published: July 2023

The relevance to the investigation stems from the fact that during military operations in Ukraine there are psychological complications both among servicemen and the population. The most common type of psychological complications is fear as one of the most mysterious and contradictory emotions. Formed in the process of evolution as a signal and warning human reaction to danger, fear often misinforms people about the extent of external danger. Fear as a psychological complication is a powerful catalyst of human physical, spiritual strength and energy and, at the same time, it can paralyze his ability to withstand danger. It is reflected in the brain, the brain organ of the central nervous system, which regulates all the most important changes in the human body. In case of stress, it is the brain structures that react first and trigger a response, the purpose of which is adaptation and survival in difficult conditions. The brain detects a threat, recognizes the cause of psychological or physical stress. In response to the influence of a stressor protective mechanisms are triggered, changing the work of the nervous and endocrine systems. The article reveals the concept of horror and its psychotraumatic effect; the most important functions of fear as a psychological complication are defined; the neurobiological basis of stress as a psychological complication during war is investigated.

Published: July 2023

The primary objective of this research manuscript is to design, develop, and evaluate an artificial neural network architecture that is capable of emulating and predicting the dynamic interaction patterns manifested during the encounter between two distinct entities. This endeavor is primarily centered around computational learning and understanding of the associated physical impulses that emerge when these objects engage in contact, elucidating the complex physical interplays therein. This process incorporates the strategic use of an extant physics engine to generate the requisite training datasets, thereby providing a robust and comprehensive foundation for neural network training and subsequent performance evaluation. In order to scrutinize and substantiate the effectiveness of the proposed artificial neural network model, this investigation also embarks on a rigorous comparative analysis. The principal focus of this comparison is to juxtapose the results rendered by the trained neural network vis-a-vis those produced by the original physics engine. The goal here is to gauge the precision, reliability, and practicality of the trained model in accurately predicting the physical impulses, thereby demonstrating its potential to stand as a feasible alternative to the traditional physics engine. Despite the initial success of this endeavor, it is worth noting that the proposed neural network system managed to achieve a range of prediction rates, oscillating between 60% and 91%, contingent upon the specific test scenario. While these preliminary results are promising, they elucidate the necessity for further optimization and refinement to bolster the model's performance and prediction accuracy.
How Can We Use Self-Determination Theory to Engage More Z Generation of Students During Onsite Classes for Learning Achievement?
Authors: Mitrea Geta
Published: July 2023

Losing their interest to the onsite classes, after COVID-19 online teaching period, the Z generation of students spent more time on their smartphones being only physically present there. The originality of this study is given by the mixed researched methods (participatory observation, sociological exploratory experiment and self-administrated questionnaire) used to collect the information and identify if receiving autonomy, competence and relatedness from the teachers, students become more engaged in courses activities and learning performance.
Contrary to our initial supposition we were able to conclude that the Z generation of students are not developing `anxiety` feelings when they are separated from their smartphones during classes if they are fully assured the autonomy, competence and relatedness for taking this decision. But, during that period their main thoughts are related to anxiety or expectation that something is to happen and they risk not to see it on their smartphone. Here we can conclude that maybe they are not aware of their dependency and do not consider that exists.
In the whole image of the three-year cohort, the extremities, 1st year and 3rd year of study are more dependent on the smartphone than the 2nd year. Also, the same study years (1st and 3rd), are more motivated and agreed with the established rules and found intrinsic motivation; as long as autonomy, competence and relatedness are accomplished for them. Maybe because 1st year students wish to better integrate into university life and 3rd year students have internalised the rules and they converged with their intrinsic motivation.
Social Construction of a Pandemic. Medicalization of Social Life - Anxiety, Frustration and Ethical Risks
Authors: Sandu Antonio
Published: July 2023

The purpose of this paper is to analyze the social construction process of the Covid-19 pandemic from the perspective of the anxiety and frustration felt by the citizens as a threat to their own lives and health and to analyze the perceived severity of the Covid-19 infection during March-June 2020. The present research aims to understand the changes that society is going through in the context of the pandemic, to analyze the social construction elements of the pandemic and the infodemic, in the context of a public health crisis, and also to identify the social perception on the pandemic among the affected population.
Social anxiety can be understood: as a side effect of the process of social construction of the person's identity, thus being correlated with the cultural particularities of the social environment of origin, mainly related to the social distinctions between individualism and collectivism; as an instance for the social construction of the idea of pandemic; as a constructive instance for the medicalization of social life in the pandemic and post-pandemic period; as being socially constructed through the mechanisms of the interpretive adrift of the meaning of role performance.
The research was carried out between March and June 2020 and it was based on a qualitative methodology derived from Grounded Theory. Data collection was done through the technique of a semi-structured interview, applied online on a sample of 103 people, mostly in the N.E. Region of Romania using an opportunity sample based on the snowball method.

Published: July 2023

This study maps the challenges public governance faces in its mission to ensure a high level of societal well-being in European countries due to complex and multidimensional analysis, both on scientific and economic levels: bibliometric analysis, vector quantisation mapping, and clustering analysis of countries. The proposed research advocates considering relevant descriptors of the two phenomena, namely the six dimensions of public governance and the composite quality of life index, to analyse their interdependence by 2020, the year for which official statistics reveal data. Our research proposes a classification of the European Union Member States from the perspective of the progress made at the governmental decision-making level for the multidimensional approach to quality of life to identify the models of good practice. The methodological support was offered by cluster analysis and a vector quantisation method, namely K-means. KNIME software has allowed us to connect to various data sources visually. Clustering of European countries has revealed several disparities thus, Denmark and Finland (which are countries with a high level of quality of life) are examples of good practices, while countries such as Romania and Bulgaria are facing difficulties in significantly improving their quality of life due to the deficiencies of the governing act. Finally, the research highlights the channels through which public governance can substantially contribute to societal well-being, keeping in mind the relatively low importance of welfare given to formal aspects of democratic representation compared to the extent of quality governance.

Published: July 2023

Introduction: Knee Osteoarthritis (KOA) is characterized by wear, tear, and it's a slowly progressive loss of cartilage, that becomes finally disabling. KOA is one of the most analyzed diseases by many medical specialties such as rheumatology, orthopedics, rehabilitation medicine, and physiotherapy. Major symptoms of KOA such as pain, dysfunction, and chronic low-grade inflammation will decrease the quality of life and eventually lead to locomotor disability. Since there are no effective ways to limit KOA progression, involvement of the endocannabinoid system (ECS) may be a non-pharmacological therapeutic alternative in the management of this disease. This study debate aspects of ways to modulate the ECS in KOA, using physiotherapeutic (PT) means such as TENS electroanalgesia, LASER biostimulation, and physical exercises with analgesic effects.
Materials and Methods: In the study, we included 82 sources, with the following keywords in the title: knee osteoarthritis, cannabidiol, endocannabinoid, inflammatory pain, analgesia, neuropathic pain, physiotherapy, electrotherapy, and LASER. To perform this review, we searched for the most relevant articles in the field of medicine and physiotherapy in 7 international databases applying inclusion and exclusion criteria.
Results: The application of TENS currents in certain doses and frequencies together with LASER biostimulation stimulates the production of endocannabinoids thus controlling pain, and stimulating the ECS. Physical exercise has an antioxidant, and anti-inflammatory role and stimulates the release of endogenous opioids.
Conclusions: The results obtained from this meta-analysis may contribute to paradigm shifts in clinical practice related to the treatment of pain by PT. TENS, LASER, and physical exercise are effective clinical tool that limits chronic inflammation and pain by involving the ECS. More studies are needed to understand endocannabinoid system involvements in KOA, and that will inspire medical doctors and physiotherapists to improve long-term treatment strategies.
Solidarity and Individualism in the Gender Relations – the Dilemma of the Power Relations within the Contemporary Couple
Authors: Apostu Iulian
Published: July 2023

The general idea regarding the relations between the contemporary marital partners describes the marital relations through a fair and modern attitude. Thus, the idea of marital modernity seems already certain and well assimilated in most marital environments. However, the national statistical data do not validate the same balance in terms of marital role equity, the relationships between partners or in terms of the distribution of power within the couple. The culture in which the young people have grown has a greater influence upon them than the glitter of the new values of equity and marital balance. In the 2000 Gender Barometer, 63% of the respondents believed it was a woman's duty to take care of the household chores, while in 2018, their share was 58%. We can therefore speak of a modernity of mentalities, but a very slow one, as in almost 2 decades, the general evolution in terms of role equity is only 5% and regarding the superior ability of the man to lead the family, the indicators note an evolution of 9.8%. (Grünberg, 2019).
The contemporaneity surprises the young couple at the intersection between the traditional system and the modern system or at the intersection between the marital modernity and the postmodernity; in both situations, the strategy of managing the solidarity and the access to power is a priority.
The study starts from the premise of the fact that the new valences of the marital modernity managed to produce obvious changes in the declared behavior rather than in the actually played behavior.

Published: July 2023

The use of collars, pedometers or activity tags is expensive to record cattle's behavior in short periods (e.g. 24h). Under this particular situation, the development of low-cost and easy-to-use technologies is relevant. Similar to smartphone apps for human activity recognition, which analyzes data from embedded triaxial accelerometer sensors, we develop an Android app to record activity in cattle. Four main steps were followed: a) data acquisition for model training, b) model training, c) app deploy, and d) app utilization. For data acquisition, we developed a system in which three components were used: two smartphones and a Google Firebase account for data storage. For model training, the generated database was used to train a recurrent neural network. The performance of training was assessed by the confusion matrix. For all actual activities, the trained model provided a high prediction (> 96 %). The trained model was used to deploy an Android app by using the TensorFlow API. Finally, three cell phones (LG gm730) were used to test the app and record the activity of six Holstein cows (3 lactating and 3 non-lactating). Direct and non-systematic observations of the animals were made to contrast the activities recorded by the device. Our results show consistency between the direct observations and the activity recorded by our Android app.
Method of the internal threads profiling at milling
Authors: Malkov O.V.
Published: July 2023

Analysis of the works devoted to thread milling showed that milling of the threads with a special profile differing from the metric profile was not sufficiently studied. Based on data of the existing threads profile analysis, the paper proposes a generalized profiling scheme using the example of a round thread. The theory of envelopes of the cutting tool positions family makes it possible to analyze the shape of the resulting thread profile and the cutting tool profiling in shaping with a kinematic scheme of thread milling with the parallel thread and tool axes. Mathematical expressions are provided that allow calculating geometric error in the round thread using the proposed method and profiling a thread cutter to form the thread of the accepted accuracy degree. The specified method could be extended to a thread with any profile described by a mathematical expression in its axial plane. Study results could be useful to the developers in designing the thread mills and to the technologists to assess the possibility of using thread milling in machining threads with the round profile.
Stress state simulation of the radial end milling cutter at shaping the complex surfaces
Authors: Ponomarev B.B. , Nguyen Van Duc
Published: July 2023

The paper presents results of simulating stress state in the cutting edge zone of the radial end milling cutter with the given tool orientation along the transverse angle. Simulation involved calculating the cutting forces in the ABAQUS program, converting them into loads acting on the tool surface, determining the contact zone of the tool front surface with chips based on the cutting theory and calculating stresses with the uniform load distribution in the considered tool section. Results of the preliminary calculations are provided. Distribution curves of the equivalent, normal and shear stresses in the cutting edge zone of the radial end milling cutter obtained using hardware of the ANSYS finite element analysis system were constructed. Simulation results allow further research to study the tool orientation and the cutting conditions influence on the tool stress state in shaping the complex surfaces. Determination of the machined surface zones, where the calculated stress values exceed the critical values, using the model makes it possible already at the initial stage of the technological process development to exclude destruction of the tool cutting edges and to achieve maximum productivity in shaping the complex surfaces.

Relevance of the research is caused by the need to increase oil recovery from wells developed in the fields of Syria, in the carbonate reservoirs of the Massif and Shiranish formation, for which there is a natural drop in production rates due to decrease in reservoir pressure, water cut, opening of reservoirs with low reservoir properties and increase in the share of hard-to-recover reserves. The main aim of the study is to analyze the results of acid treatments to improve oil recovery in the field of Suwaydia, Syria. The object of study is the carbonate complexes in the Upper Cretaceous deposits of the Massif formation and the Shiranish formation, Syria. Methods: review of domestic and foreign experience in treating the bottomhole formation zone using acid compositions and analysis of production, technological, lithological, geological, geophysical, and field data of wells treated with acids. Results. The paper introduces the advantages of the acid treatments method, such as improving the reservoir permeability and decreasing the skin factor by increasing the pore space and fracture channels, as well as removing the filter cake and various inorganic sediments that prevent oil flow. The undesirable effects of acid treatments: corrosion, secondary sedimentation, water cut, are indicated. The geological and physical conditions of the well and reservoir for choosing a treatment technology are considered. They are: reservoir temperature, filtration, and reservoir properties of rocks, granulometric (fractional) and mineralogical composition of rocks, chemical composition of reservoir fluids. The main directions of measures for solving geological and technological complications that arise during acid treatments using inhibitors, new multicomponent compositions of acid agents, special additives, and multi-stage treatments are noted. The paper introduces the technology and results of the application of acid treatments: hydrochloric acid treatment and foam hydrochloric acid treatment of the bottomhole zone of wells located in the north-east of the Syrian Arab Republic, which belong to the two oil field – Suwaydia and Zarba – of the Al-Hasakah Oil Fields Administration. It was noted that the use of a simple hydrochloric acid treatment of several wells did not lead to the predicted increase in oil recovery, and the use of an acid mixture (HCL at a concentration of 15 %, HF at a concentration of 3 %) in well no. 462 of the Suwaydia oil field showed an increase in productivity of 1,5 times. Recommendations are given for improving acid treatments at the Suwaydia, Syria fields to intensify oil production.

The study is relevant due to the need to identify dangerous sections of oil and gas pipelines located in underdeveloped and sparsely populated areas, due to the development of dangerous geological processes. This study aims to assess the intensity and forecast the development of karst-suffusion processes within the pipeline route located in southern Yakutia, and to determine the most significant factors that activate this process. Methods: processing engineering and geological survey data, digitization of geological maps and decoding satellite images to build factor maps that affect the activation of the karst process: geological structure of the route; curvature, slope, surface exposure; map of surface drainage density and density of total tectonic fracturing. We created a map of the density of karst occurrences along the route according to the route survey and data from engineering and geological surveys during construction. We compiled a map of the susceptibility of the route territory to the development of karst-suffusion processes based on the Frequency Ratio method. Results. We carried out a description of the engineering and geological conditions of the pipeline route. To assess the karst-suffusion hazard of the pipeline route, calculations were made of the expected sizes of sinkholes in the base of structures using the method of G.M. Shakhunyants. Using the method of the ratio of particulars, the correlations between factors and foci of karst occurrences along the pipeline route were obtained. The susceptibility map developed on the basis of these results makes it possible to determine specific site boundaries for determining solutions for monitoring the development of the exogenous process and optimizing the pipeline operation processes. Therefore, the application of such methodology can be applied to other extended gas and oil pipelines located in difficult geological conditions.

Relevance. Currently, drilling companies affect up to 30 % of productive time to combat differential grabs. The development of drilling fluids that contribute to the reduction of differential tacks is an urgent task. It is known that nanodisperse particles have a positive effect on the technological process of drilling wells, in this regard, the issue of developing nanostructured drilling fluids for drilling companies is in demand. Experimental studies have been carried out at the Department of Oil and Gas Engineering and Technology of the South-Russian State Polytechnic University (Novocherkassk Polytechnic University) and highly inhibited drilling fluids with the addition of nanodispersed copper with a concentration of up to 4 % and a particle size from 40 to 80 nm have been developed at the level of inventions. It has been experimentally established that the addition of nanoparticles of nanodispersed copper to highly inhibited drilling fluids improves rheological, lubricating and anti-seizure performance. Nanodispersed copper particles in the drilling fluid help to reduce the surface tension at the separation of the two phases – drilling column – filtration crust, which helps to reduce the probability of differential tacks. The aim of the purpose of the research is to study the properties of the developed highly inhibited water-based solutions with the addition of nanodispersed copper, as well as to study their rheological, filtration, lubricating and anti-seizure capabilities. Objects: highly inhibited drilling fluids and their main properties. Methods: experimental-analytical method for studying the addition of copper nanoparticles to the properties of the drilling fluid. Results. Laboratory studies of the effect of copper nanoparticle additives on the quality of the drilling fluid were carried out. The effect of dispersed copper nanoparticles on the main parameters of the drilling fluid was established.
Storage Behaviour of Groundnut (Arachis hypogaea L.) Seeds under Different Storage Condition
Authors: Gayathri M. , Jerlin R. , Eevera T. , Amuthaselvi G.
Published: July 2023

Background: Seed deterioration is an unavoidable process during seed storage resulting in declined germination and vigour of the seeds and the seeds have different storage potential under different storage condition. Maintenance of germination and vigour requires new alternative method of storage conditions viz., packaging material and temperature conditions. Storage potential of groundnut seeds cv. VRI 8 and the changes associated with the seeds stored under different storage conditions were investigated in this study. Methods: The efficiency of modified atmospheric storage with different combination of CO2, N2 and O2 and vacuum packaging under different storage temperature (25°C, 5°C and -5°C) for maintaining the storage behaviour of seeds up to 8 months were evaluated and the gas mixture was checked in gas analyzer at regular intervals. Result: The seeds stored under modified atmospheric storage (MAS) condition with a gas mixture of 0% CO2, 100% N2 and 0% O2 at -5°C temperature condition, maintained germination and seed vigour above 70% with a minimum increase in seed moisture content even after 8 months of storage and even when these seeds kept under ambient condition also maintained germination above 70% after 8 months of storage while the seeds stored under ambient condition registered less germination of below 70% by 6 months of storage itself. Down-regulation of antioxidant defence system viz., catalase and peroxidase activity and the minimum accumulation of malondialdehyde and H202 content in the embryo indicated the less oxidative damage in the seeds stored under MAS compared to ambient condition. Thus, the study highlighted that the seeds have better storage potential under modified atmospheric storage condition with low atmospheric temperature through maintaining the seed quality by reducing their metabolic activity and storing these seeds under ambient condition could be a cost-effective method.

Background: Aflatoxicosis is a major disease affecting ducklings especially due to their high susceptibility during the post-natal stage. There is no vaccination schedule for this disease as aflatoxins are haptens and incapable of generating immune response by itself. Methods: In this study to combat this malady, in ovo vaccination with an aflatoxin-chicken ovalbumin conjugate was done on 25th day of incubation to generate adequate immune response during the post-natal period of ducklings. An isolate of Aspergillus flavus was used for harvesting of the aflatoxin. The purified crude toxin was checked by TLC to observe the presence of all 4 isomers. Chicken ovalbumin was used as carrier protein due to its similarity with duck ovalbumin as well as to avoid autoimmunity. The conjugate was then encapsulated with chitosan to prevent clearance of the antigen as well as to provide a balanced Th1/Th2 response. A booster dose of the conjugate was given on 14th day post hatch along with sheep red blood cells. The antibody titre was checked by passive haemagglutination test. Result: The results seen i.e., Log2 antibody titre of 1.33±0.21 proved that an immune response was generated. This could provide protection to the ducklings against aflatoxins. Also, this is the first time in ovo vaccination in ducks with aflatoxin-chicken ovalbumin conjugate has been carried out.

Background: A two-year field study was conducted at the ICRISAT research farm during the rainy seasons of 2021 and 2022 to investigate the impact of crop geometry, crop establishment method and sustainable nutrient management practices on nutrient availability pattern and growth of hybrid pigeon pea. Methods: The experiment followed a split-split plot design. The collected data was analysed using radar graph and heat maps for nutrient availability and dry matter respectively. Result: Data revealing that transplanted plots registered higher nutrient availability and proportionate root and total dry matter production at various growth stages. Among plant geometry the root and total dry matter production was higher with 100×100 cm. when considering planting methods, transplanting with a square system of 100×100 cm, combined with an integrated nutrient management approach consisting of 150% (or) 100% soil test based NPK, vermicompost at a rate of 5 t ha-1, phosphate-solubilizing bacteria (PSB) and seed treatment with Rhizobium, resulted in average of 31.5% higher dry matter production over alone inorganic nutrient management practices. Thus, a square geometry of 100×100 cm, along with sustainable integrated nutrient management (100% soil test based NPK, vermicompost at a rate of 5 t ha-1, PSB and seed treatment with Rhizobium), resulted in higher nutrient availability and dry matter production. These findings highlight the importance of careful selection of planting methods, crop geometry and nutrient management practices for maximizing the nutrient mining for production of high dry matter production of hybrid pigeonpea.

Entrepreneurship development in Pesantren (Islamic boarding schools) is an important thing to do so that they become independent. This study aims to reveal and elaborate on three things, namely: the concept of kiai leadership in developing entrepreneurship in pesantren; strategies for developing entrepreneurship in pesantren; and the benefits obtained by pesantren and the surrounding community with the development of entrepreneurship in pesantren. The data were obtained from two pesantrens that have been successful in developing entrepreneurship, namely pesantren Sidogiri and pesantren An Nur 2. Data collection is done through interviews, observation, and documentation. All data were analyzed using domain and componential analysis techniques. The results of the data analysis show that the kiai's concept for developing entrepreneurship in pesantren is collective-collegial, democratic-participatory, and consultative-authoritative. While the strategy carried out by the Kiai is to build and maintain trust, empowerment, synergy, innovation, flexible policies, and solid cooperation. The benefits of the results of entrepreneurship development in pesantren are felt and enjoyed by various parties, namely: first, the availability of basic necessities for students, alumni, teachers, pesantren and surrounding communities. Second, the opening of new job opportunities for the community, especially residents around the pesantren. Third, pesantren have economic independence, so that they are authoritative and independent in regulating and managing pesantren. The research has implications for the development of entrepreneurship based on religious values.

Purpose: Given the importance of sustainability in the supply chain, the aim of this study was to analyze the effect of supplier environmental damage on managers' perception of the need to develop Green Purchasing Dynamic Capabilities (GPDC), and whether this effect is mediated by environmental concern

Methodology/approach: This study employed a full-factorial vignette-based experiment Participants were 267 US professionals with management experience. The hypotheses were tested through multiple regression analysis.

Originality/Relevance: This study is one of the first to analyze the role of management in decision-making on the development of GPDC, as well as analyzing the effect of the origin of environmental damage and the way in which the manager was inserted in the context of supplier selection.

Key findings: Responsibility for supplier selection did not show a direct effect on the need to develop GPDC. The controllability for the origin of the environmental damage does not moderate the effect of the responsibility for the selection of the supplier in the necessity of GPDC development. However, environmental concern mediates the effect of responsibility on the need for GPDC development.

Theoretical/methodological contributions: The findings motivated to elucidate how the external and internal aspects of the company in relation to the environmental damages of the supplier interact in the Dynamic Capabilities of Green Purchasing.
