Surgical Treatment of Cranioshisis and Meningocele in a Newborn Calf Summary Congenital cranial diseases pose life-threatening risks to all animals and include cases that can result in death. In this study, we aimed to provide information about a case of meningocele due to craniosis in a 1-day-old male Simmental calf. Clinical and radiographic examinations revealed cranioschisis and meningoceles in the calf. The operative procedure was performed considering the favorable general condition of the animal. During the operative procedure, the skin piece forming the swelling on the skull was removed with an elliptical enzyme, and the cranial defect with a diameter of 4 cm was closed by narrowing the connective tissue in the region. Intraoperative complications were not observed. In the postoperative follow-up, the calf did not show any neurologic findings in the 2nd week and 2nd month controls and the general health status of the calf was good. In conclusion, in this study, it was thought that early intervention in small defects and treatment of the defect with tissue sutures could be successful, and it may be important to evaluate the operative procedure instead of euthanasia in diseases with poor prognosis.

Authors:   Agricultural Academy, Institute of Animal Science – Kostinbrod, Yanchev Ivan
Published: December 2024

The aim of the present study was to evaluate the effect of increased CO2 l evels a s a c ompound
of mixed emissions from a poultry housing (transported by an air duct into a greenhouse), on lettuce’ trace
elements content. The experiment was carried out at the experimental poultry farm of the Institute of Animal
Science - Kostinbrod in May and June, 2019, for 40 days. During the experiment the following parameters
were controlled and measured both in control and experimental greenhouses (lettuce groups): average level of
CO2, indoor air temperature and relative humidity, - three times a week during irrigation at noon by handset
IAQ Monitor SM-2100; Average level of ammonia (NH3) - three times a week during irrigation at noon by
handset Aeroqual Series 200 Monitor. At the end of the experiment, soil and plants samples from both groups were taken and tested for the content of 15 microelements - Vanadium (V), Chromium (Cr), Manganese (Mn),
Cobalt (Co), Nickel (Ni), Copper (Cu) , Zinc (Zn), Arsenic (As), Selenium (Se), Molybdenum (Mo), Silver (Ag),
Cadmium (Cd), Tin (Sn), Mercury (Hg) and Lead (Pb) by mass spectrometry with inductively coupled plasma
(ICP-MS). The obtained results show that the triple increase in the cobalt concentration in the experimental
group (P <0.001) can definitely be associated with the increased photosynthesis and the expected Vit. B12 levels.
Of interest are also the levels of the elements vanadium and chromium – respectively, 3.3 and 10.7 times higher
in the experimental group compared to the control group (P <0.001). The content of copper and selenium in the
plants corresponds to their high level in the soil, but in copper the accumulation in the experimental group is
suppressed (P <0.01), while for selenium we can assume that CO2 stimulates to some extent its accumulation (P
<0.05).
Arşiv Belgeleri ve Kroniklere Göre Kıbrıs Seferi’nin (1570-1571) İlk Çıkarma Safhası
Authors: Tanrıvermiş Abdullah
Published: December 2024

Osmanlı Devleti’nin 16. yüzyılın ilk çeyreğinde, Mısır ve Suriye’nin fethi sonrasında Doğu Akdeniz’i çevreleyen bölgede yayılmaya başlaması, bu hâkimiyet sahası içerisinde kalan ve muhasımın ileri deniz karakolu durumunda bulunan Kıbrıs’ın fethini; askerî, ekonomik, siyasî ve coğrafî bir zorunluluğa dönüştürmüştü. Zira bu bölgede kurulan egemenliğin istikrarı ve devamı Doğu Akdeniz’de deniz kontrolünün tesis edilmesine bağlıydı. Bu kontrolün sağlanması Akdeniz’in üçüncü, Doğu Akdeniz’in ise bu en büyük adası olan Kıbrıs’ın hâkimiyet altına alınmasıyla mümkündü. Bu maksatla 1570 yılında ada üzerine düzenlenen sefer 1571 yılında başarıyla neticelenmiş, Kıbrıs 1571 yılında fethedilerek Osmanlı egemenliğine girmiştir. Osmanlı Devleti açısından stratejik bir öneme sahip olan Kıbrıs adasına sefer düzenlenmesi kararı alındıktan sonra, kara ve deniz unsurlarının sefer hazırlıkları başlamıştır. Bu hazırlıkların başarılı bir neticeyle sonuçlanması günümüz modern askerî terminolojisinde amfibi harekât olarak adlandırılan, çıkarma harekâtının başarılı bir şekilde icrasına bağlıydı. Zira başarılı bir çıkarma yapılarak kıyı başının tutulabilmesi ve muharip birliklerin karaya çıkarılmasıyla daha sonra yapılacak olan kara harekâtı gerçekleştirilebilirdi. Bu sebeple askerî açıdan bir adanın fethinin ilk aşamasını, başarılı bir çıkarmanın gerçekleştirilmesi oluşturmaktaydı. Bu anlamda Kıbrıs seferinde, çıkarmayı gerçekleştirecek olan Osmanlı donanmasının İstanbul’dan demir alması sonrasında amfibi harekâtın yükleme noktasına seyri, yükleme noktasından bindirmenin yapılarak Kıbrıs’ın güneyine çıkarmanın gerçekleştirilmesi, kıyı başının tutulması sırasında yaşanan ilk çatışmalara dair bilgi temin edilmesini sağlayan arşiv belgeleri, kronikler ve muhtelif çalışmalar bulunmaktadır. Bu çalışmada kavramsal ve analitik açıdan daha ziyade Kıbrıs seferinin ilk çıkarma safhası sürecine değinilerek, harbin başarısı için oldukça mühim olan amfibi harekâtın icrası, çıkarma sonrasında yaşanan ilk çatışmalar, Kıbrıs adasına köprü başı tutularak düşman bölgesine çıkarmanın gerçekleştirilmesi, böylece muhasara birliklerinin harbe hazır hale gelmesi gibi gelişmeler üzerinde durulacaktır.

Published: December 2024

Objective: This study aimed to investigate the predictive relationships between social anxiety and the psychological constructs of rumination, self-focused attention, and social intimacy among women. Specifically, it sought to determine how these variables influence the levels of social anxiety in a female population.

Method: A cross-sectional design was utilized, with a sample size of 350 female participants determined by Morgan and Krejcie's table. Standardized measurement tools were employed, including the Liebowitz Social Anxiety Scale (LSAS) for social anxiety, the Ruminative Responses Scale (RRS) for rumination, the Self-Focused Attention Scale (SFAS) for self-focused attention, and the Miller Social Intimacy Scale (MSIS) for social intimacy. Statistical analyses included descriptive statistics, Pearson correlation, and multiple linear regression, conducted using SPSS version 27.

Findings: Descriptive statistics showed mean scores of 45.23 (SD = 11.56) for social anxiety, 52.14 (SD = 12.75) for rumination, 30.56 (SD = 8.49) for self-focused attention, and 40.85 (SD = 9.22) for social intimacy. Pearson correlations revealed significant relationships between social anxiety and rumination (r = 0.61, p < 0.001), self-focused attention (r = 0.58, p < 0.001), and social intimacy (r = -0.49, p < 0.001). The regression model was highly significant (F = 320.77, p < 0.001), explaining 65% of the variance in social anxiety (R² = 0.65, R² adjusted = 0.64).

Conclusion: The study confirmed that rumination and self-focused attention significantly predict social anxiety, with social intimacy showing a protective effect. These findings underscore the importance of addressing cognitive patterns and enhancing interpersonal relationships in interventions aimed at reducing social anxiety among women.

Environmental Performance of the Shipping Industry: A Case Study of MARPOL Violations
Authors: Palippui Habibi
Published: December 2024

Focusing on key areas such as sulfur emissions under MARPOL Annex VI, oil discharge violations, and other pollution infractions, the research explores trends in non-compliance, the geographical distribution of violations, and the effectiveness of regulatory enforcement. The results reveal a significant increase in sulfur violations following the introduction of stricter global fuel sulfur limits in 2020, with older vessels and ships registered under flags of convenience being the primary offenders. The analysis shows that regions with robust port state control (PSC) regimes, such as Northern Europe and North America, have lower rates of non-compliance, while areas with weaker enforcement, including Southeast Asia and Africa, exhibit higher violation rates. Regression analysis further indicates that stricter penalties and more frequent inspections correlate with improved compliance. Qualitative insights from case studies underscore cost pressures, technological challenges in retrofitting older ships, and flag state weaknesses as major drivers of non-compliance. To address these issues, the study recommends strengthening global enforcement, harmonizing penalties across jurisdictions, and incentivizing investments in pollution control technologies. The findings suggest that the International Maritime Organization (IMO) could play a critical role in coordinating these efforts, ensuring consistent regulatory standards and enforcement. The study concludes that achieving full compliance with MARPOL regulations is essential for reducing the environmental impact of the shipping industry and aligning it with global sustainability goals.
Effect of Relaxation Times on Magnetization of Blood Proton Spins at Steady State using Improved Bloch NMR Fluid Flow Equation
Authors: Rasheed Lateef , Adam Usman , Pascal Timtere , L. Emeka Agada , Salau Rilwan
Published: December 2024

Nuclear magnetic resonance (NMR) is a phenomenon that involves the absorption and re-emission of electromagnetic radiation by blood proton spins flowing through human vessels. NMR is governed by Bloch NMR fluid flow equation, which can be used to define the magnetization of blood proton spins. In the existing literature, the Bloch NMR fluid flow equation has been derived, and it has been observed that the equation does not incorporate certain NMR and blood flow parameters. In this paper, we derived a novel Bloch NMR magnetization flow equation that encompasses NMR parameters such as Larmor frequency of spinning protons and static magnetic field. We utilized the principle of dimensional homogeneity to check the validity of our newly derived NMR flow equation. Furthermore, we investigated the effect of transverse relaxation times of arterial, venous and capillary blood on magnetization of blood spinning protons. We employed Laplace transform method to obtain the steady state solution of the improved Bloch NMR fluid flow equation. MATLAB and Origin software tools were used for data analysis and simulations. Results showed that for varied transverse relaxation times of arterial, venous and capillary blood, respectively, the magnetization distribution of blood spinning protons consists of two components: the linear and the non-linear components. The findings of the study also indicated that capillary blood proton spins exhibit phase coherence. The simulated results may be used by spectroscopists to improve the accuracy of NMR/magnetic resonance imaging (MRI) experiments.

It also examines the potential for improving accessibility, especially in areas where record retrieval is often delayed or compromised by bureaucratic bottlenecks. By evaluating case studies and existing applications of blockchain technology in record management, this research identifies opportunities and challenges for blockchain adoption in Nigeria's public and private sectors. Through a mixed-method approach that includes surveys and interviews with key stakeholders in data management, the study highlights the feasibility of integrating blockchain into Nigeria’s personal records system. The findings suggest that blockchain technology, despite certain challenges such as cost and technological infrastructure, can significantly enhance the security and accessibility of personal records in Nigeria. Recommendations for policy development, technological investment, and further research are also provided.
An Analytical Observation of Soret Effects and Double Diffusive Convection in between Vertical Plates
Authors: Sani Hadiza Nass
Published: December 2024

The Soret effect in fluids is a thermodynamic phenomenon in which different particles respond in different ways to varying temperatures which has been studied by the Swiss chemist Charles Soret, has been difficult to examine in detail on Earth because of gravity. The SCOF (Soret-Facet) is the first investigation to verify Soret conditions in steady and changing conditions and was conducted in space. The objective of this study is to present a mathematical observation of a sample taken in a vertical channel formed by two infinite vertical parallel plates to study Soret effect as an alternative to expensive space experiments. It studies the heat transfer of a fluid in a channel with one moving relative to the other, driven by two different rates of diffusion and observes how different particles in that fluid respond to varying temperatures. The methods employed on the governing coupled-nonlinear momentum and energy equations obtained from Navier-Stokes equations are implicit finite difference using FORTRAN. Exact solutions form integration are obtained for steady state dimensionless velocity, concentration, temperature for a fully developed flow using MATLAB. It is observed that time, bouyancy ratio and thermophoretic coefficient increase velocity at hot plate. These results are applied to studies in mass transport with heat and energy, including those in the Earth’s interior, oceans, atmosphere and in the refinement of crude oil. Conclusions are drawn from graphical representations of fluid velocity and fluid concentration for various parametric values.

Published: December 2024

The use of composites in various fields has increased rapidly due to their advantages such as convenience, stability, tensile, flexural and impact resistance. Mechanical properties in textile composites are closely linked to fiber reinforcement. Flax fibers are used with various polymer materials. The most common matrix material used in flax fibers is epoxy polypropylene, as it is easy to process and has good mechanical properties. Flax fiber reinforced composites have high tensile, flexural and impact strength. Compared to other natural fibers, composites made with flax fibers are costly. In this study, a composite surface was obtained by applying epoxy polymer to the surface of flax fiber reinforced fabric of different lengths and the mechanical properties of the resulting composite samples were examined. As a result of the testing of composites made of flax fibers, tensile strength measured between 17.76 and 26.62 MPa, flexural strength between 28.82 and 46.92 MPa and impact strength of 2.39-5.25 J were measured. The results obtained show that improvements were achieved in the mechanical properties of epoxy resin and flax fiber reinforced polymeric composite materials.

Published: December 2024

This paper explores the possibilities to develop students’ lifelong learning (LLL) competencies via supporting their personal development process (PDP) in engineering education. Despite the recognized importance of LLL, its embedment in learning outcomes remains limited. A survey revealed that both engineering students and educators value LLL competencies, but perceive them to be taught and evaluated only to a limited extent. This paper introduces a PDP model to support educators in fostering students’ LLL competencies. The model, developed through literature review and educators’ input, includes (1) a matrix with various interventions, such as e-portfolios, reflective writing, and student-centred teaching, categorised by different criteria, such as educator and student investment, and (2) a PDP flowchart that aids educators in selecting suitable interventions according to their goals and context. The paper concludes with recommendations for educators to integrate LLL competencies into their teaching practices, emphasising the need for time, tools, and support to effectively implement these interventions.

The purpous of this study are to To determine the current OSH practice and determine OSH aspect that needs improvement based on Health Ministry Regulation No.52 of 2018. qualitative methods with a case study design. Occupational Safety and Health (OSH) management at Padangsari Health Center was evaluated based on 92 indicators from three main aspects. In the OHS management criteria, 14 out of 23 indicators (60.9%) have been met. For OSH standards, 45 out of 61 indicators (73.8%) have been met. Meanwhile, 8 indicators related to OSH training, reporting, and recording have all been met. Although Padangsari Health Center has achieved "Main" accreditation with an achievement of 72.8%, further efforts are still needed to meet at least 80% of the assessment indicators in order to obtain the highest accreditation, namely "Plenary". It is recommended to improve indicators, especially in improving OHS planning, strengthening supervision, ensuring staff compliance with SOPs, and evaluating the effectiveness of OSH implementation in the future.

Groundwater quality in coastal areas is responsive due to the interaction of fresh water with seawater. Groundwater quality monitoring studies in coastal area needs to be done regularly to prevent natural disasters and clean water crises in the future. In this study, measurements of groundwater physics parameter were carried out, i.e. electrical conductivity to analyze groundwater quality. The interpolation method based on Geographic Information Systems (GIS) was used to obtain values ​​between each sample point to produce a spatial distribution map of groundwater quality over the research location. The results of the study showed that groundwater quality in the coastal area of ​ Durung Village was generally still quite good with conductivity values ​​between 689 - 3,391 µS/cm. However, for the locations which is nearby the coast such as in the location of Malahayati Merchant Marine Polytechnic, it was indicated that it had been contaminated by seawater with the highest conductivity values between 5,763 – 6.270 µS/cm.
Comparative analysis of biomechanical characteristics of knee flexion and extension muscles in volleyball physical training
Authors: Yu Guishen
Published: December 2024

This study aimed to analyze the biomechanical characteristics of knee flexion and extension muscles in volleyball physical training from the cellular and molecular biomechanics aspect. Multiple training modes like strength, elasticity, and comprehensive training were chosen to systematically evaluate relevant characteristics of these muscles among volleyball players. Advanced devices such as 3D motion capture systems, ground reaction force platforms, and electromyography equipment were used to gather precise biomechanical data. At the cellular and molecular level, different trainings impact muscle cells differently. For example, strength training might enhance the synthesis of contractile proteins within cells, while elasticity training could influence the elasticity-related molecular structures. With multidimensional data analysis, the effects of various training modes were compared. The comprehensive training group had a kinematic flexion extension angle of 528.27º ± 11.49º, an angular velocity of 135.52º ± 5.97º, and an angular acceleration of 3177.02º ± 116.88º, performing best. This could be due to its comprehensive influence on cellular and molecular processes in muscles, promoting better coordination and force generation. This article offers a theoretical basis for volleyball players to create scientific training plans and gives practical tips for coaches and athletes to optimize programs and prevent injuries. By focusing on cellular and molecular biomechanics, it fills research gaps and helps boost the development of biomechanics in volleyball physical training.
Analyzing the influence of physical posture on audience perception in mass media presentations
Authors: Wu Yihan
Published: December 2024

Non-verbal communication, especially physical posture, affects audience perception. From a cellular and molecular biomechanics angle, different postures may trigger unique intracellular responses. Upright or leaning forward postures might activate neural pathways that enhance neurotransmitter release related to positive perception. In contrast, a slouched posture could disrupt normal cellular signaling, potentially leading to a less favorable audience perception. This study explores the impact of four postures on audience views in a media setting, aiming to offer data on how posture shapes key perceptions and provide valuable insights for Mass-media Presentations (MMP), despite limited prior research on this aspect. A within-subject experimental design was employed, with 34 participants observing media presentations under four posture conditions. Posture was the independent variable, while credibility, trustworthiness, engagement, and authority were the dependent variables. Data were collected using surveys, posture monitoring devices, and eye-tracking data. Statistical analyses, including Analysis of Variance (ANOVA) and paired t-tests, were conducted to determine significant differences between posture conditions. Upright and leaning forward postures were associated with the highest audience ratings for credibility, trustworthiness, engagement, and authority. Slouched posture consistently led to the lowest ratings across all measures. The ANOVA results revealed significant differences in perceptions of engagement (F = 10.21, p = 0.0008) and credibility (F = 8.67, p = 0.0013). Paired t-tests and post-hoc analyses confirmed that upright posture significantly outperformed slouched posture across all metrics, with large effect sizes (Cohen’s d > 1.0). Posture significantly influences audience perceptions in mass media presentations. Upright and leaning forward postures enhance credibility, trustworthiness, engagement, and authority, while slouched posture diminishes these perceptions. These findings provide practical insights for media professionals, suggesting that careful attention to posture can improve the effectiveness of media presentations. Future research could investigate how gestures and facial expressions interact with these cellular and molecular mechanisms to shape audience engagement.
Analysis of cellular and molecular biomechanical correlates in emotional response monitoring via biosensors and their impact on teaching strategy modification in Japanese language instruction
Authors: Chen Yongping
Published: December 2024

Emotion states have a significant impact on language acquisition and learning outcomes. In Japanese language teaching, traditional strategies often overlook students' emotional responses, which can lead to stress and disengagement, affecting performance. To address this, the study focuses on incorporating bio-sensor-based emotional reaction monitoring. At the cellular and molecular biomechanical level, emotions can trigger a cascade of physiological changes. For example, stress can activate the hypothalamic-pituitary-adrenal (HPA) axis, leading to the release of stress hormones like cortisol. These hormonal changes can affect neurotransmitter systems and cellular signaling pathways in the brain, influencing cognitive functions related to language learning. During Japanese language sessions, teachers' emotional states are recorded using surveys and EEG monitoring. The EEG signals can provide insights into the neural activity and related cellular and molecular events. Participants are divided into experimental and control groups. In the experimental group, teaching strategies are adjusted based on emotional monitoring data. The Extreme Gradient Boosting (XGBoost) model classifier is used for EEG signal feature selection to create a stress level identification model. This model can help in understanding the cellular and molecular correlates of stress during teaching. Statistical analysis evaluates the relationship between EEG features and stress levels, as well as the effectiveness of adjusted teaching strategies. Tailored teaching strategies based on these insights can enhance teacher resilience and improve the classroom environment. By considering the cellular and molecular biomechanical aspects of emotions, the study aims to improve teacher well-being and student learning experiences, leading to more effective Japanese language instruction.
