Endometritis is one of the most frequently detected diseases of cattle, which is associated with disturbances in the microbial balance of the uterine cavity. This pathological process leads to disturbances in animal fertility, and, consequently, to economic losses in the dairy industry. In this regard, it is important to carry out timely preventive measures and have effective drugs for the treatment of postpartum endometritis. The aim of this study was to evaluate the effect of drugs based on bovine recombinant interferon "Biferon-B" and "EnrofloxacinferonB" on the taxonomic composition of bacteria in the uterine-vaginal discharge of patients with acute postpartum catarrhal endometritis of cows using high-throughput sequencing. It was found that the dominant species in the uterine cavity of cows with endometritis were Porphyromonas levii, Bacteroides heparinolyticus and Fusobacterium necrophorum. Bacterial taxa capable of causing various cattle diseases were detected in uterovaginal secretions. It was found that therapy of cows with the drug "Biferon-B" after 24 hours led to a tendency to increase the number of Caviibacter abscessus, Mycoplasmopsis californica and Histophilus somni. Statistically significant differences were found in the number of Porphyromonas SGB1983 before therapy (0.9%) and after therapy with "Enrofloxacinferon-B" during the first 24 hours (9.6%) (p<0.05). The study of the microbial diversity of utero-vaginal secretions of cows during therapy with "Enrofloxacinferon-B" on the seventh day established a tendency to decrease the relative abundance of bacteria Bacteroides heparinolyticus, Trueperella pyogenes and Mycoplasmopsis californica. The obtained data expand our understanding of the etiology of acute postpartum catarrhal endometritis in cows and the effect of drugs based on species-specific interferons on the course of this disease.

Authors: Siddique Kamran
Published: January 2025

This research examines the impact of Hybrid Warfare on Pakistan's peace and conflict situation. It identifies that Pakistan faces challenges primarily from its eastern neighbor, with involvement from other states and non-state entities, making the situation complex. Hybrid warfare in Pakistan utilizes social failures, economic disparities, political marginalization, and demographic inequalities. The strategies employed focus on non-kinetic methods to achieve objectives. To counter these threats, it is crucial to understand the objectives, methods, and resources behind non-kinetic strategies. Developing awareness and understanding of hybrid threats is crucial in order to develop an integrated approach to countering these challenges. The study recommends an awareness campaign on hybrid threats for state entities, the government, law enforcement, and the public to achieve a unified response. It also stresses the need for institutional capacity development to handle a diverse range of threats through centralized control and decentralized execution. Additionally, a comprehensive review of internal security policies and strategies is necessary to effectively counter the tools used in hybrid warfare.

An appraisal of the Nigerian defense policy and national security
Authors: Obiajulu Francis Afamefuna
Published: January 2025

Defence policies encompass various state activities aimed at ensuring national security (NS), integrating international security and military decisions to protect sovereignty and interests. These policies guide when and how to engage national armed forces, with evolving strategies reflecting each nation’s development and global context. Sun Tzu's view in The Art of War underscores the crucial role of defence, stressing its necessity for a state’s survival. Major shifts in American defence strategy post-September 11 involved proactive measures against terrorism, aiming to prevent the spread of weapons of mass destruction. Similarly, China’s National Defense Policy (NDP) highlights its adaptability to international political shifts. Defence policies thus structure a nation’s NS approach, steering its armed forces to uphold sovereignty, economic goals, and global responsibilities. This study explores the link between defence policies and NS, assessing their challenges and impacts, particularly in the context of Nigeria.
Operational efficiency of the multinational joint task force and peace in the Lake Chad region
Authors: Dodo Yusuf Muktar
Published: January 2025

The Lake Chad Basin (LCB) countries created the Multinational Joint Task Force (MNJTF) in 2012 to address the Boko Haram crisis, which started in Nigeria in 2002. Recognizing that the problem was regional, not just Nigerian, the countries of the Lake Chad Region (LCR) - Benin, Cameroon, Chad, Niger, and Nigeria - agreed to improve cooperation. In 2015, the MNJTF headquarters was attacked by Boko Haram, which led to increased military responses from the LCR countries. However, almost a decade later, the MNJTF has not achieved its goal of eliminating the Boko Haram threat due to challenges such as funding, equipment, and structure. These challenges have undermined peace in the region and diverted attention from other threats faced by LCR countries. This research proposes measures such as appropriate funding, equipment, and structure to enhance the effectiveness of the MNJTF. Implementing these recommendations is expected to contribute to peace and stability in the Lake Chad Region and Africa as a whole.
A Comparative Analysis of English-Medium Instruction at the Universities of Messina and Trento: Lecturers’ Opinions, Goals, and Concerns
Authors: Polli Chiara
Published: January 2025

This paper aims to partake in the ongoing debate on English as a Medium of Instruction (EMI) in Higher Education (HE), starting from the lecturers’ point of view. It is grounded on the empirical data of a quantitative research originally conceived by the Interdisciplinary Laboratory for the Quality and Innovation of Didactics (LIQuID) of the University of Trento and then extended to the University of Messina. As a first step, LIQuID developed a questionnaire to investigate EMI lecturers’ opinions on institutional and didactic objectives and teaching practice (codeswitching, in-class interaction, teaching tools), comparing, when possible, their experience of teaching in their first language (L1) and second language (L2). The data collected refer to EMI modules offered in Trento in the academic year 2018-2019. Since several studies about HE in Italy highlighted how the approaches towards EMI vary between Northern and Southern Italian universities (Pulcini & Campagna, 2015; Costa, 2017), as a further expansion of this research project, Trento’s questionnaire was proposed to Messina’s lecturers who taught EMI classes during the academic year 2023-2024. This enlarged the dataset and made it possible to carry out a comparative analysis of these two HE contexts. This paper provides an overview of this comparison by discussing similarities and differences in the opinions and experiences of EMI lecturers in Trento and Messina. By examining the findings of this ongoing research project, this study ultimately reflects on the role of language in EMI lecturing and the changes in the lecturers’ approaches to teaching in L1 and L2.
Form and Function of Teachers’ Questions in EMI Contexts: Comparing Practices Across European Countries
Authors: Cicillini Stefania , Triki Nesrine
Published: January 2025

Previous literature on engagement strategies in the classroom, especially in EMI contexts, has evidenced that lecturer questions play a vital role in establishing teacher-student interaction, checking and scaffolding comprehension, and supporting students’ learning progress (e.g., Costa & Mariotti, 2023; Dafouz-Milne & Sánchez-García, 2013). While the effect of different disciplines on the nature of teacher questions is still controversial, no studies have looked at the probable impact of teachers’ cultural academic background related to the country of origin. Drawing on a corpus of 30 EMI lectures from five European countries (Croatia, Denmark, Italy, Spain, and the Netherlands), this study analyzes and compares the use of questions as an engagement strategy and offers insights into teacher discourse. The overall results indicate that teachers in different cultural academic contexts use questions with different frequencies and select different question forms to serve particular functions. The study may have pedagogical implications, especially for teacher education programs.
Addressing Engineering Students’ Needs in EMI Contexts: A Focus on Comprehension and Pronunciation
Authors: Johnson Jane Helen , Picciuolo Mariangela
Published: January 2025

Effective lecture comprehension in English-Medium Instruction (EMI) contexts is crucial for student learning, particularly when taught by non-native English (NNS) speakers. This study investigates the specific needs of engineering students, emphasizing the impact of lecturers’ pronunciation on effective comprehension. Intelligible pronunciation and its relation to comprehension (Munro & Derwing, 1995) are central to this exploration. Students’ judgment of NNS lecturers’ pronunciation accuracy significantly influences their comprehension (Munro & Derwing, 1995; Valcke & Pavón, 2015). Kornder and Mennen (2021) note that learners’ linguistic backgrounds affect their perception of accented speech, which then impacts their evaluation of teaching quality (Jensen, 2013). This study involves a survey of 104 students (both Italian and international), attending MA lectures in engineering taught in English by Italian L1 lecturers. Students were asked to evaluate their lecturers’ pronunciation and indicate whether it interfered with their comprehension of the lectures. It also includes assessment of a lecture attended by some of the students surveyed, recorded and transcribed, in order to compare students’ subjective impressions of lecturer discourse with objective observations of lecture delivery. Findings reveal that students’ perceptions of EMI lecturers’ language performance and their comprehension in the classroom are influenced by several different factors, which affect comprehension regardless of the lecturer’s actual English language skills. This study highlights the importance of understanding and addressing the specific needs of engineering students in EMI contexts. By focusing on factors that influence lecture comprehension, we can develop more effective pedagogical strategies and training programs for both EMI lecturers and students.
Comparison of sialic acid content in bovine and buffalo milk and meat
Authors: Contò Michela , Rinaldi Simona , Failla Sebastiana
Published: January 2025

Animal-origin food, such as meat and milk, are important sources of sialic acids (SIAs) with relevant implications for human health. Two significant SIAs in mammals are N-acetyl-neuraminic acid (Neu5Ac) and N- glycolylneuraminic acid (Neu-5Gc). Neu5Ac is the major form of SIAs in all mammalian tissues, and it is an essential nutrient for the development and function of the brain. Neu5Ac differs from Neu5Gc by a single oxygen atom, but humans cannot synthesize the Neu5Gc due to a genetic mutation. Thus, Neu5Gc causes a human antibody response, which promotes the inflammatory processes. On the other hand, animal products are excellent sources of Neu5Ac, which has a high nutritional value. A diet with Neu5Ac/Neu5Gc ratio higher than 5 is recommended to inhibit the absorption of Neu5Gc. This ratio is rarely reached in red meat, so it is considered potentially carcinogenic. This study aimed to determine the concentrations of Neu5Ac and Neu5Gc in the milk and meat of buffalo and cattle and to evaluate the ratio of Neu5Ac/Neu-5Gc. The study was conducted on 12 bulk milk and 12 samples of Longissimus thoracis for each species. Samples were collected from Friesian bovine and buffalos raised in farms located in Central Italy. The concentration of the two types of  SIAs was determined by the reverse phase (RP) high-performance liquid chromatography (HPLC) procedure of SIAs released from glycoconjugates through acidic hydrolysis and derivatized with 1,2-diamino-4,5methylen- edioxy-benzene (DMB). Data was analyzed by ANOVA using a bifactorial model with interactions (products and species). Both products and the species influenced the content of Neu5Ac (p<0.001 and p<0.014, respectively) and Neu5Gc (p<0.001, for both). Neu5Ac content was significantly higher in buffalo milk than in cow milk (1045 vs. 906 μg/g protein). In contrast, Neu5Gc content was significantly lower in buffalo milk than in cow milk (58 vs. 106 μg/g protein). On the contrary, there was no significant difference in Neu5Ac meat content in the two species (473 μg/g protein, on average). In contrast, Neu5Gc content was significantly higher in cattle meat than in buffalo meat (228 vs. 83 μg/g protein p<0.001). Buffalo products showed a Neu5Ac/Neu5Gc ratio greater than 5 (18.5 for milk and 6.4 for meat), while beef meat had a ratio of 2.2 (less than 5). In conclusion, due to the high amount of Neu5Ac and the limited presence of Neu5Gc, buffalo products could have an exciting effect on human health.
Buffalo whey proteins performance at the oil/water interface: rheology characterization of the interfacial films

Published: January 2025

Whey proteins can form thin layers at the interface of non-miscible liquids like oil drops and water by emulsifying. The interfacial activity and the rheology of the interfacial films constitute a crucial aspect in assessing ingredients’ ability to form and stabilize emulsions. Although cow-origin whey protein concentrates (WPC) have been extensively used in the food industry, the WPC from buffalo (BWPC) still needs to be studied. In this context, the objective of this work was to explore the interfacial activity and the viscoelastic properties of BWPC at the oil-in-water (O/W) interfaces. WPC was used for comparison. With this purpose, BWPC and WPC were dispersed at 2.6x10-3 – 1.6% w/v in 10 mM phosphate buffer (pH 7) and equilibrat-ed at four °C for 24 h. Then, the equilibrium interfacial pressure (πeq) was registered through the Wilhelmy plate method. Additionally, adsorption dynamics at the O/W interface at protein concentrations of 0.5 and 1% were obtained over three h with a drop tensiometer. Subsequently, the rheological dilatational behavior (10% deformation amplitude and 0,1 Hz of angular frequency) was evaluated. Plate tensiometry showed that πeq of BWPC and WPC solutions increased from 9.9 to 16.7 mN/m and 11.5 to 15.0 mN/m, respectively, and conform protein concentration increased. An intersection between π – concentration isotherms was observed, indicating that below protein concentration of 1.3x10-2%, the πeq of WPC was higher than BWPC. This observation could be attributed to compositional differences and the possibility of generating different structural patterns in the interface. The drop tensiometer displayed that π increased with time for both protein concentrates, indicating the protein adsorption at the O/W interface. Interfacial rheology results indicated a gradual increase in the solid or elastic character (Ed) over time for both types of proteins, indicating more cohesive and packed structures. Ed of BWPC was higher than WPC at the lowest protein concentration, while the opposite also occurred. This behavior can be explained by considering that the higher the protein concentration, the stronger interactions among BPWC proteins occur. In conclusion, BWPC increased the interfacial pressure to a greater extent than WPC and concomitantly formed films with a higher solid character. These findings contribute to considering the use of BWPC as an efficient emulsifier agent with the benefits of adding value and minimizing the environmental impact of this byproduct.

In Bangladesh, A Techno-Economic Evaluation of Rice Straw Based Power Generation
Authors: Hossain Arman , Zilani Md. Abdul Kader , Mostafa S.M.G , Alam M. Shafiul
Published: January 2025

The Availability of sufficient electrical energy is essential for a nation’s economic growth to be steady. Bangladesh should, therefore, have enough electricity infrastructure to maintain its economic growth. Several kinds of agricultural waste are available in Bangladesh as an agricultural country. Therefore, Bangladesh may generate energy (such as electricity) from this enormous agricultural waste. One of the potential agricultural wastes for use as a source of energy is rice straw, but only if it is properly and methodically processed. This research investigates the technical potential of using filtered rice straw to produce energy in Bangladesh. Environmental risks are posed by the estimated 4 million tonnes annual burn of rice straw in an open field. Rice straws can produce a net annual electricity output of 217.21 GWh, corresponding to an input of 8640 tonnes of rice straw, according to simulation and full-scale experiments. But our country’s available rice straw is almost 119.3 million tonnes/year. Notice that we used 17-tonne rice straw in the aspen simulator. The plant can reduce CO2 emission of 0.03%. Total cost is $4,082,005 per year, and the per unit cost is $0.019. This thesis work aims to present a concept for producing electricity in Bangladesh’s rural areas using rice straw. Small and medium-sized power plants based on rice straw are very helpful for producing and distributing electricity in rural areas. A comprehensive process model for biomass gasification in a twin-fire fixed bed gasifier is developed using the ASPEN PLUS simulator. The chemical process industries primarily use the process modeling tool Aspen Plus for process monitoring, optimization, and conceptual design. This simple course on the Aspen Plus Simulation engine will teach you how to model the most common chemical plant unit operations.
A Performance Analysis on Matrix Factorisations in Solving Musical Instrument Source Separation Problem
Authors: Tang Wen Kai Adrian , Ng Wei Shean , Liew How Hui
Published: January 2025

Audio signal decomposition breaks a mixture of musical instrument audio signals into its fundamental musical instrument components. Machine learning is one of the methods widely used in audio signal decomposition. However, the limitation of computer hardware and the complexity of the algorithm may cause the computational speed of machine learning to deteriorate. This paper aims to use the contemporary matrix factorisation to extract the fundamental musical instrument audio signal component from the mixture of musical instrument audio signals. We choose nine contemporary matrix factorisation techniques and compare their performance in separating the mixture of musical instrument audio signals. We create five scenarios with different melody complexity to test the matrix factorisation techniques. Based on the Signal-to-Noise Ratio, Nonnegative Matrix Factorisation with Kullback-Leibler Divergence (NMF-KL) is the best separation performance when the monotonic noise is not added to the mixture of musical instrument audio signals. Initially, NMF-KL has good separation when monotonic noise is added to the simple recurring mixture of musical instrument audio signals, but as the melody complexity increases the NMF-KL separation performance starts to deteriorate. Lastly, the matrix factorisation techniques do not work well when the white noise is added to the mixture of musical instrument audio signals.

Structural, Optical, and Electronic Properties Analysis of Praseodymium Doped ZnO: Insights from Density Functional Theory with GGA+U Approach
Authors: Ferdush Jannatul , Bhuiyan Shuvo Md Al Amin , Haque Badhan Shahriar , Islam Jahirul , Islam Md. Ashraful , Hasan Md Mahadi
Published: January 2025

ZnO is widely used as a semiconductor material due to its wide bandgap, high exciton binding energy, and excellent transparency in the visible range, which make it suitable for optoelectronic applications. Doping in ZnO is important because it allows for controlling its electrical properties, enables the tuning of conductivity, and enhances its functionality for specific applications. Doping can introduce new energy levels within the bandgap. Moreover, it improves the performance of ZnO-based devices. This study explored the structural, optical, and electronic properties of pure and Praseodymium ion (Pr3+) doped ZnO using GGA+U based DFT. Results agreed with prior research, showing compatible lattice parameters and band gap for pure ZnO. Increasing Pr concentration expanded lattice parameters and volumes while reducing the energy band gap. Pr doping shifted the Fermi level to the upper conduction band, causing an overlap between the conduction and valence bands. This indicated a transition from a semiconductor to an n-type degenerate semiconductor with metal-like characteristics. Higher doping concentrations led to a shift in density of states towards lower energies. Computed optical properties exhibited red shifts in absorption peaks and increased absorption in the near and far ultraviolet regions following Pr doping. Similar red shifts were observed in the reflectivity spectrum and other optical properties. The real dielectric constant (ε1 (ω)) displayed negative values, signifying metallic behavior at specific photon energies, consistent with band structure optimization.
Automatic Detection and Classification of Diabetic Retinopathy from Optical Coherence Tomography Angiography Images using Deep Learning - A Review
Authors: M.A Abini , S Sridevi Sathya Priya
Published: January 2025

Diabetes-related retinopathy (DR) is a microvascular complication of diabetes that affects many people (DR). Both the prevalence of DR cases and the number of diabetics worldwide have risen considerably. DR weakens vision and can lead to full or partial blindness if ignored. Ocular visual serves as a crucial instrument in detecting, assessing, handling, and recording DR. Over the last few years, advances in technological imaging have enabled the creation of images with improved readability and comparison while requiring significantly less time, effort, and disruption. The choriocapillaris and retinal microvasculature can be studied using optical coherence imaging the procedure is based on differences in floating in blood cells (OCTA). Additionally, OCTA can find preclinical microvascular anomalies that appear before clinically evident DR symptoms. To identify and categorize diabetic retinopathy in OCTAimages, deep learning algorithms may be developed. By using DL techniques, such as CNNs, the images can be analyzed and features extracted for accurate diagnosis.In this paper, we want to offer readers a review of Diabetic retinopathy classification techniques utilizing machine learning and deep learning from OCTAimages, as well as a summary of the various OCTA datasets currently in use for this purpose. Also, we confirmed that the proposed model could work by comparing its performance to that of anML-based categorization tool that uses manually created features extracted from OCTA images. This review gave an overview of recent studies on DL-based image analysis models for OCTA images. It also addressed possible problems with clinical deployment and future directions for research.

This study presents a methodology for reducing power losses in distribution power systems through the incorporation of both fixed and uncertain photovoltaic (PV) generation, utilizing the Particle Swarm Optimization (PSO) technique. The proposed approach aims to address the unpredictability of PV generation and optimize the placement and size of Distributed Generation (DG) units to minimize I2R loss in the distribution network. The main focus is on how to minimize the existing losses occurring in the distribution system. In the distribution system the I2R loss amount is higher compared to the transmission system. The reason behind the high amount of I2R loss in the distribution system is due to the high ratio, high current and low voltage. To reduce these losses, several researchers provide solutions, such as network reconfiguration, capacitor allocation, DG allocation, and DSTATCOM allocation. In this research I have focused on DG allocation solution for reducing the I2R loss. I have determined the most suitable photovoltaic generation capacity and location to minimize power loss in the system using the PSO algorithm. The PSO techniques can accurately determine the optimal locations for PV generation in the IEEE-33 bus and IEEE-69 bus radial feeder, which preserves power quality for consumers and reduces energy loss during distribution. To conduct this study, three simulation scenarios were employed, namely: a) the base case, b) without accounting for the uncertainty of solar irradiance and load demand, and c) considering the uncertainty of solar irradiance and load demand. The comparison between the three scenario results will also be shown in the results section for both the IEEE-33 and IEEE-69 bus systems. MATLAB R2021a was utilized to evaluate the algorithm's effectiveness in the IEEE-33 and IEEE-69 bus systems

Published: January 2025

The China-Europe Railway Express, also known as the China-Europe Freight Train, is a flagship initiative of the Belt and Road Initiative (BRI). Since its inception in 2011, it has linked over 200 cities in China and Europe, establishing itself as a critical logistics channel. This study employs quantitative and qualitative analyses to examine seven years of news reports from China Daily, the Middle East News Agency (MENA), and PR Newswire. Using the LexisNexis news database and AntConc software, the study explores high-frequency keywords, collocations, and clusters within the corpus to identify reporting trends and biases. The findings reveal that Chinese media coverage significantly exceeds that of international outlets, which frequently contextualize the railway within the broader BRI framework, indicating limited global familiarity. Moreover, Chinese media focus on the railway’s economic benefits, whereas foreign outlets highlight specific hub cities and development projects.The study recommends that Chinese media adopt a more targeted approach, emphasizing individual routes, specific cargo types, and localized benefits to enhance global understanding and support for both the BRI and the China-Europe Railway Express.

The main purpose of the article is to form an effective methodological approach to identifying key social and humanitarian imperatives for ensuring sustainable development and the level of their influence. The object of research is the system for ensuring the sustainable development of Ukraine. The scientific task is to identify key social and humanitarian imperatives and assess their impact on sustainable development through the established methodological approach. The methodology includes the method of semantic networks in synthesis with the method of predicate language construction. At the same time, a formalized description method was used. Recommendations were made on the impact of one of the key imperatives As a result of the conducted research, a scheme of mutual understanding of imperatives and a matrix of priorities that were most significant for Ukraine were formed. The obtained result is extremely important for information support of national security and sustainable development. Possible limitations of this study include the specificity of the context, in particular, that key socio-humanitarian imperatives were largely associated with military action, which is typical for the situation in Ukraine, but may not be common in other countries. Future research prospects may include expanding the analytical framework to include additional imperatives and factors that may impact sustainable development and national security in a changing global context.

Este artigo apresenta um estudo sobre a importância dos cuidados necessários para evitar rupturas na construção do conhecimento geográfico e garantir sua continuidade de aprendizagem na transição dos Anos Iniciais aos Anos Finais do Ensino Fundamental. A partir disso, busca-se avaliar a necessidade da disciplina de Geografia para a formação do cidadão, procurando evidenciar sua contribuição simbólica nos dois ciclos e destacar posturas e atitudes específicas. Como objeto de estudo, foram selecionadas duas escolas de Marechal Cândido Rondon – PR, em uma pesquisa qualitativa, com utilização das técnicas de levantamento bibliográfico e documental. Também, utilizou-se a técnica de análise do conteúdo dos cadernos de alunos de uma turma de 5º ano e duas turmas de 6º anos. Para completar as informações, realizou-se entrevistas com os professores das respectivas turmas. Neste sentido, a pesquisa identificou que essa transição exige uma atenção especial, pois, é imprescindível que o professor conheça a Ciência que ensina (no caso, a Geografia) e que é nesse momento transitório que se precisa demonstrar a mesma intensidade de conteúdo, compreendendo o grau de continuidade necessário.
