Authors: Tella Adetunmbi
Published: March 2024

The study explored the entrepreneurial prospects of animal breeding and genetics from the viewpoints of undergraduates at two Nigerian institutions. The study looked at how undergraduates perceive the potential for entrepreneurship in the fields of animal breeding and genetics; it determined whether they intend to pursue entrepreneurship in any of the identified fields of the discipline; and examined the relevance of the curriculum to the entrepreneurship knowledge needed to succeed in the fields; and identified the difficulties that these undergraduates might face in their entrepreneurial intention endeavors. The study adopted a qualitative methodology to explore the entrepreneurial prospects of animal breeding and genetics from the viewpoints of undergraduates at two Nigerian institutions.  30 undergraduate students from two universities were taken to represent the sample for the study. An open-ended survey created on Google form was used for the collection of data.  The link of the Google form was sent to the students’ platform in the Department of Animal Genetics in the two selected universities. The findings demonstrated that Animal Breeding and Genetics undergraduate students perceive the potential for entrepreneurship in animal breeding and genetics to be numerous including setting up animal clinic, animal breeding laboratory, establishing a poultry business, setting up a consultancy outlet on animal breeding and genetics, among others.  Majority of the undergraduate students indicate their intention to pursue entrepreneurship in animal breeding and genetics instead of looking for the white-collar jobs.  Furthermore, the current curriculum in Animal Breeding and Genetics in the two universities are very relevant to the fields and the knowledge they have gathered so far is enough to succeed if taking into entrepreneurship after the completion of the bachelor’s degree programme. The challenges envisaged by the respondents include lack of initial capital to setting up entrepreneurship business in Animal Breeding and Genetics, cooperation, understanding and support from parents and family members, government policy including registration of the business, among others. Data and information gathered through the administration of the open-ended survey was analysed thematically following the objectives of the study. The study drew it conclusion based on the findings from the study and also makes appropriate and relevant recommendations.

Can the puma Messi, the cheetah Gerda, the panther Luna, the wolf Kira be considered pets? (man in culture and the animal world)
Authors: Rozin Vadim Markovich
Published: March 2024

The article discusses a new trend to have wild animals (big cats, foxes, ferrets, etc.) in some homes, and it turns out that since they have been raised since childhood, loved and cared for, they behave like pets (dogs and cats). The question is whether these animals can still be considered domestic or not. To solve this problem, characteristics are given that make it possible to distinguish between wild and domestic animals, and the question is raised whether they can be applied to this case. To understand this new class of animals, the concept of "anthropomorphic" is introduced and it is shown that their psyche differs from that of wild animals, it is closer to domestic ones. An explanation is offered for the experiments of geneticist Dmitry Belyaev on the domestication of silver foxes.   The author argues that the evolution of foxes was influenced by two factors, not only genetic selection, as Belyaev believed, but also the impact of the environment created by man, an environment conducive to the formation of anthropoids. Attention is drawn to the fact that humans continue to crowd large wild animals. Humans increasingly need land for goats, cows, horses, pigs, poultry, and agricultural land. The paradox ‒ our big cats of anthropoids are fed the meat of these pets. At the end of the article, Belyaev's hypothesis, according to which we are "self-domesticated" monkeys, whose innate psychological tendencies, behavior and social structure have radically changed under the influence of selection for reduced aggressiveness, is compared with the author's hypothesis about the role of signs in human origin. He shows that domestication occurred as a result of the transition of hominids to "paradoxical behavior", which required the creation of a sign based on a signaling system. The latter allowed the hominids to act contrary to biological evidence at the command of the leader. A necessary condition for this was the imagination conditioned by signs, which helped to invent the first tools.
On the issue of classification of legal research
Authors: Osipov Mikhail Yur'evich
Published: March 2024

The purpose of the study is to determine the features and criteria for classifying legal studies in terms of their completeness and sufficiency of coverage of all possible varieties of legal research. In the framework of this study, issues related to the justification of the allocation of additional types of legal research are also considered: the division of all legal research into "positive" and "critical"; criteria for the relationship between these types of research are identified. Also, this article discusses possible errors in conducting "positive" and "critical" legal research, and gives their typology. The ways of preventing mistakes in conducting legal research are also determined. The research methods, the results of which are presented in this article, include general scientific methods: analysis, synthesis, induction, deduction, abstraction, generalization, modeling. In addition to the criteria for classifying scientific legal research existing in legal science, it is proposed to distinguish "positive legal research" and "critical legal research" into independent types of scientific legal research. At the same time, legal reality always acts as the object of "positive research" in jurisprudence, in the form of interrelated and interacting phenomena of social reality, while the subject of positive research is always any patterns describing and explaining legal phenomena, or the legal side of certain social phenomena; the object of "critical" research in jurisprudence is supported by any legal theories, concepts and hypotheses. The subject of "critical legal research" is a critical analysis of a hypothesis, concept or theory in legal science. If the purpose of "positive legal research" is to discover new patterns of formation, development, functioning of legal phenomena, or to identify defects and develop scientifically sound proposals for improving the legal regulation of a particular sphere of society, then the purpose of "critical" research in legal science is to determine the validity of a particular scientific theory, hypothesis or concept.

Magnetoplasma rocket engine has a broad application prospect in the deep space exploration, manned space flight and other space missions. The ion energy is converted into the directed velocity in the magnetic nozzle of the engine. The investigation into the detachment process of the plasma with the magnetic field is of great significance for improving the engine propulsion efficiency. However, there are roughly five kinds of physical mechanisms which can all contribute to the detachment process and make the detachment in the magnetic nozzle quite complicated. Furthermore, the ion temperature is much higher than the electron temperature in the magnetic nozzle of the magnetoplasma rocket engine due to the heating effect of the ion cyclotron resonance stage. As a result, previous numerical model which were based on the assumption of cold ions are unapplicable for the simulation of the engine. In this work, a fluid simulation model is developed which is used for simulating the magnetic nozzle in the magnetoplasma rocket engine. The model includes the electron and the ion of single charge. For the characteristics of the magnetoplasma rocket engine, the ion energy equation is added into the governing equations. In order to analyze the effect of the inertial detachment, the static electric field due to the charge separation is also included. The simulations are performed under the conditions of different inlet ion temperatures and background magnetic fields. The results show that the ion axial velocity gradually increases in the magnetic nozzle and the ion stream lines detach from the magnetic field lines gradually. The loss of adiabaticity is the dominant mechanism in the detachment process. The ion axial velocity increases with the inlet ion temperature rising, and the ion streamlines detach earlier from the magnetic field lines. The resistive diffusion is unaffected by the inlet ion temperature while the detachment interfaces of other three mechanisms all move toward the upstream. With the increase of the background magnetic field, ion axial velocity decreases and the angle included between the streamline and the axis becomes smaller. The loss of adiabaticity is still the dominant physical mechanism when the magnetic field is changed.

Neutral atom array serves as a crucial experimental platform for studying many-body physics, quantum computing, and quantum simulation. In this work, we describe in detail the experimental process of preparing a one-dimensional homogeneous single atom array containing 40 Cs atoms, including the dipole trap array generation device, atomic array fluorescence imaging, and the uniformity optimization of the dipole trap array. The beam waist of the dipole trap is about 1.8 μm, and the spatial resolution of the imaging system is higher than 1.55 μm. The non-uniformity of dipole trap array is mainly caused by the intermodulation effect of multi-tone signal during amplification. The uniformity of the dipole trap array is optimized to 2% (Fig. (a)) by measuring the fluctuations of the dipole trap intensity and the light shift of trapped atom, and providing feedback to adjust the phase and amplitude applied to the multi-tone RF signal on acousto-optic deflectors. Furthermore, the uniformity of oscillation frequency, loading rate, and lifetime for trapped atom in the dipole trap array are measured. These results show that oscillation frequency has a uniformity within 2% (Fig. (b)); mean loading rate is around 58% with a uniformity within 3%; and mean lifetime of single atom in dark trap is around 6(1) s with a uniformity within 8%.

Open quantum system, coupled with an external bath is a key research field of quantum physics. Steady state is the state in which any initial state converges after a long time and is usually of the most interest. However, relatively speaking, the nonequilibrium dynamical processes of quantum many-body systems have been rarely studied. This is mainly due to the fact that quantum many-body systems generally have interactions, and the Hilbert space required for a complete description of their dynamical processes will grow exponentially with the number of particles increasing, and the computational difficulty will increase dramatically as well. Hence, it is a difficult problem to completely describe their dynamical processes completely. With the development of quantum technologies, the interest in the nonequilibrium dynamics of open quantum many-body systems is aroused. A common phenomenon is the metastable state, where the system initially relaxes into a long-lived state and then converges to the final stationary state for a longer time. In this paper, we establish a low-dimensional approximation to describe the metastability dynamics in Markovian open quantum system, based on the spectra of the Liouvillian super-operator. The separation of time scales implies a splitting in the spectrum, and this spectral division allows us to eliminate the fast decay modes by using the perturbation method, and then we establish the effective description in the low-lying eigenmodes subspace. Furthermore, we study the dynamics process of the Rydberg atomic system under electromagnetically induced transparency (EIT) conditions and find that the system can handle metastable dynamics if the atomic interactions are considered. We compare the effective dynamics in the subspace with the actual dynamics in the full space, and the results show that the effective dynamics works well on condition that the perturbation approximation holds. Our work provides a feasible idea and method for establishing an effective and simplified description of the dynamical process of open quantum many-body systems.

Authors: Bhat Malathi S , Braggs Anston Vernon , Mynalli Soujanya
Published: March 2024

Introduction: Acute pulmonary embolism is a life-threatening condition that can lead to sudden death. Pulmonary Artery Hypertension (PAH) can be found in the setting of acute pulmonary embolism. The Egg and Banana sign and Carina Crossover (CCO) sign are seen in PAH, which are present on Computed Tomographic scans (CT scans). Aim: To determine the accuracy of CT scans, the Egg and Banana sign, and CCO sign seen in PAH in the evaluation of pulmonary embolism. Materials and Methods: This retrospective, cross-sectional study was conducted from May 2019 to May 2021 in the Department of Radiodiagnosis at Father Muller Medical College Hospital in Mangalore, Karnataka, India. The CT scans of 102 consecutive patients who underwent CT Pulmonary Angiography (CTPA) for suspected pulmonary embolism were evaluated for the presence of the CCO sign and Egg and Banana sign. The CCO sign was considered positive when the right pulmonary artery (PA) was seen crossing anterior to the carina at its bifurcation. The Egg and Banana sign was considered present when the PA was found lateral to the aortic arch, with the PA described as the Egg and the arch as the Banana. The results were statistically analysed using Statistical Package for Social Sciences version 3.0. Results: Pulmonary embolism was seen in 26 out of 102 cases, with a mean age of 60.2±16.27 years. Pulmonary embolism was absent in 76 cases with a mean age of 55.8±17.11. An equal gender distribution was seen in 26 cases of pulmonary embolism. The Egg and Banana sign was found in 8 out of 26 patients with pulmonary embolism and had a specificity of 78.9%, negative predictive value of 76.92%, and diagnostic accuracy of 66%. The CCO sign was seen in 14 out of 26 cases of pulmonary embolism and had a higher specificity of 81.58% and diagnostic accuracy of 74.51%. The CCO sign had a statistically significant value in detecting pulmonary embolism. Conclusion: According to the study, the CCO sign had a higher accuracy in detecting pulmonary embolism compared to the Egg and Banana sign. The accuracy was further improved when combined with other signs of pulmonary embolism.

Introduction: Stature is one of the most commonly used anthropometric dimensions for identification purposes in forensic investigations and for assessing the development and growth of individuals. It is well-known that various anatomical anthropometric parameters can accurately estimate stature. Aim: To estimate stature among healthcare workers in Himachal Pradesh using linear regression equations based on percutaneous anthropometric parameters of the upper limbs and trunk. Materials and Methods: This cross-sectional study was conducted on healthcare workers at Dr. Rajendra Prasad Government Medical College, Kangra, Tanda, Himachal Pradesh for a one year (September 2021-August 2022) duration. The study included 360 healthy healthcare workers from the Himachal Pradesh population, 180 females and 180 males, aged 21 years and above. Stature, arm span, Biacromial Breadth (BAB), and forearm length dimensions were measured for each subject. Statistical analysis was done using Microsoft Excel and Epi-Info version 7.1 software. The Pearson Correlation Coefficient was used to determine the correlation between stature and different anatomical anthropometric parameters. Linear regression equations were developed to estimate stature, with significance set at p-value ≤0.001. Results: The mean age of the study population was 41.33±28.91 years. The descriptive anthropometric parameters measured in the study were as follows: stature 162.4±6.85 and 149.4±7.15, arm span 165.67±7.5 and 150.31±8.33, right forearm length 26.68±1.33 and 24.36±1.59, left forearm length 26.47±1.30 and 24.30±1.55, BAB 34.11±2.16 and 31.74±2.32, respectively for males and females. Conclusion: The regression equations derived from this study can be valuable for estimating stature in situations where accurate stature measurements are not feasible.
Ewing’s Sarcoma of the Mandible with Extensive Bony Metastasis in a Young Male: A Case Report
Authors: Karmakar Malay , Dutta Somlina , Sahu Suparna , Bhadra Ram Chandra
Published: March 2024

Ewing’s Sarcoma Family of Tumours (ESFTs) comprises locally aggressive, undifferentiated small round blue-cell tumours of neuroectodermal origin, predominantly seen in adolescents. These tumours arise from non random chromosomal translocations involving the Ewing’s Sarcoma (EWS) gene. ESFTs in the mandible are uncommon. A 14-year-old male patient presented with a painless swelling in the right jaw. Plain radiographs, ultrasonography, contrast-enhanced Computed Tomography (CT), and Magnetic Resonance Imaging (MRI) revealed a large, partially well-defined, highly vascular soft tissue mass in the right mandibular region. It measured approximately 80×82×75 mm (anteroposterior x transverse x craniocaudal), with both solid and cystic components. The mass was destroying the underlying right temporomandibular joint, head, ramus and posterior body of the right hemimandible, including extensive sunray-type bony spiculations. There were multiple lytic lesions in the skull and facial bones, as well as, altered marrow signal intensity in the calvarium, bilateral humeri and clavicles, and cervical and thoracic vertebrae, indicating a locally aggressive tumour with extensive metastasis into the bones and marrow. The diagnosis was confirmed by histopathology, which showed fibrocollagenous tissue infiltrated by sheets of small round cells with scanty eosinophilic cytoplasm and prominent nuclei. Management typically involves a combination of chemotherapy, radiation and surgery. However, metastatic Ewing’s Sarcoma has a poor prognosis.

This article raises the issue of the threat that may be posed to Polish internal security after the end of hostilities in Ukraine by former soldiers and volunteers fighting on the Ukrainian side. When discussing cross-border crime, the author points to areas that may be of interest to informal veterans’ organizations, as well as to the possibility of penetrating the criminal world of former military personnel. Presenting threats, the author also points to tasks for the Polish border protection system in the field of combating organized crime.
A MODEL OF INTERNAL AUDITORS’ MANAGEMENT SYSTEMS ASSESSMENT COMPLIANT WITH ISO 45001
Authors: PACANA Andrzej
Published: March 2024

Internal audits are a requirement of point 9.2 of the ISO 45001 standard. They are a very good tool to improve the management system, but also the entire organization. Audits and the auditors conducting them should be improved. Therefore, this article aims to develop a model for evaluating internal auditors of occupational health and safety management systems according to ISO 45001. The model includes both the guidelines of the ISO 19011 standard and expert knowledge resulting from experience in assessing auditors. The following tools are adequately integrated: the SMART(-ER) method, brainstorming (BM), and control sheets. The result is the estimated quality of the auditor’s work. Rankings created using this model cannot be used to punish auditors; the model is intended to help chart an improvement path for internal auditors. Due to its nature, the model can be used to assess internal auditors in any management system. It can also be modified according to the original solutions in the field of auditing in a given organization.
THE POWER STATUS OF ASIAN AND PACIFIC REGION STATES ON THE BASIS OF SYNTHETIC POWER MEASURES FROM 1992 TO 2022

Published: March 2024

This paper presents power status in Asia and the Pacific region states – an issue that has a major impact on the international security of countries. To illustrate this, the study takes the period after the end of the Cold War, from 1992 to 2022. The purpose of the paper is to characterize the power status of the Asian and Pacific region countries based on synthetic power measures, adopting the powermetrics model of Professor Mirosław Sułek to calculate the power of states. The analysis proves that the most important role in international security is played by the countries known as superpowers and world powers, whose power enables the implementation of relevant strategic goals, especially in such an important region as Asia and the Pacific. In the coming decades, there is a high probability that China will gain the status of a superpower, while the US must fight to maintain its global position among the rapidly developing countries of the Asia-Pacific region, which in the game for power may take away some of Washington’s current advantage.

The province of Northern Samar, its municipalities including Pambujan, is a place abundant of Manihot esculenta Crantz (cassava), and Cocos nucifera Linn. (coconut). However, its industry is mainly limited to food production. This study developed biofilms from cassava starch (CasS), and coconut flour (CoF) with polyvinyl alcohol (PVA). The physicochemical properties were analyzed to determine their pH, solubility, moisture content, and tensile strength. Functional groups were investigated using FTIR, and the antibacterial properties were evaluated. The results showed that both biofilms with PVA were weakly acidic and insoluble in all solvents. Meanwhile, CoF biofilm contained higher moisture content than the CasS biofilm. CoF biofilms also carried more weight and higher force than CasS biofilm. Hydroxyl, alkyl, and alkene functional groups were identified for both biofilms. Meanwhile, both biofilms showed no inhibitory effect against E. coli, and S. aureus. Therefore, the developed biofilms with PVA showed good physicochemical properties and can be used for packaging applications. The slight acidity can prolong their shelf-life. Moreover, both will not easily dissolve. CoF biofilm comprised more water than CasS but both are still suitable for packaging due to their tensile strength attributed to the presence of the functional groups. However, CasS, CoF, and PVA do not have antibacterial properties. More physicochemical tests, further characterization, and incorporation of antibacterial agents were recommended.
Is Agriculture Still the Mainstay of Rural Economies? Insights from Ultra-Poor Households in North-central Nigeria

Published: March 2024

Aims: Nigeria may be facing aging and decline in the population engaged at food production nodes, posing huge challenge to agri-food systems with poverty at risk of deepening. Current trend in rural-urban migration and occupational mobility raises the open question of: “Is agriculture still a mainstay of rural economy, playing reliant roles in income and employment generation for the ultra-poor in Nigeria rurality?”. Understanding this is important because structural change to agricultural workforce in Nigeria has far-reaching implications on food security, welfare, and poverty. We sought to unfold the dynamics of agriculture as a business among ultra-poor rural households in North-Central Nigeria. First, we investigated engagements of ultra-poor rural households in agriculture. Secondly, we examined their level of commercialization. Lastly, we investigated determinants of ultra-poor’s market participation and its intensity.
Study Design: This study used quantitative primary data collected in surveys and qualitative data generated from focus group discussions.
Place and Duration of Study: The study was carried out in three states in North-central Nigeria viz: Kwara, Kogi, and Niger with data collected and analyzed between 2020-2022.
Methodology: We randomly selected 1588 households (out of 60,427 households) from the “Single Register of the Ultra-poor” operationalized on a World-Bank-Assisted Conditional Cash Transfer (CCT) programme. We analysed data using descriptive statistics, Household Agricultural Commercialization Index, and Double-Hurdle Model.
Results: Only about 18.7% of the ultra-poor households were primarily engaged in agriculture with the focus groups highlighting conflicts issues from indiscriminate grazing activities as primary reason for the abandonment. Determinants of market participation and intensification include: (-) household dependency ratio, distance to markets, (+) linkage to market agents, access to mechanization and input market, CCT-beneficiary status, and farm size (p<0.05).
Conclusion: Involvement in primary agricultural production is declining in Nigeria. We recommend a boost to infrastructural development of the rurality to support agricultural transformation and attractiveness to the next wave of youths.
