Authors: Kuqali Margarita , Plaku Megi 
Published: December 2024

This paper aims to dwell on students’ perceptions and attitudes towards metaphoric terms and some approaches that contribute to the comprehension and acquisition of basic physics metaphoric terminology for 1st-year undergraduate engineering students. Physics English terminology comprehension and acquisition is of great importance when it comes to these students. Being the lingua franca of today, mastering the basic terminology of the respective field of interest in English is demanding for everyone who aspires to have a deep understanding of their field of interest and a prosperous career in the future. To have an effective input and output in the teaching/learning process a collaboration among professionals of STEM (science, technology, engineering, and mathematics) and ESP (English for Specific Purposes) is necessitated. Physics is fundamentally dependent on abstract notions that frequently lack tangible counterparts, such as in these metaphoric terms "tunneling effect" or "black hole". Concepts expressed through such metaphoric terms assist students to envision, conceive, and acquire the latter, but can also hinder their understanding of concepts. To conduct this research, a semi–structured questionnaire was handed to 100 students of Polytechnic University of Tirana to investigate their beliefs towards these terms and to determine different approaches that will contribute to their understanding of the above-mentioned terms. The results concluded that students face challenges in comprehending a metaphoric unknown term. Nevertheless, the results indicated that the most used and preferred approaches to learning these terms are related to the professor’s assistance with explanation, analogy with everyday experiences, and visual aids, videos mainly. This study highlights the importance of collaboration between STEM and ESP in combining the linguistic-semantic nature of terms and their practical application in the function of students’ terminology acquisition.

Methods: One hundred and fifty (150) laboratory-confirmed SARS CoV-2 infected, severe cases in Intensive Care Unit/ High Dependency Unit were included. These cases were divided into two categories, i.e., with and without mediastinal lymphadenopathy on High Resolution Computed Tomography chest. The two categories were compared on the basis of data obtained including age, gender, comorbid, White Blood Cell count, lymphocyte count, median days of hospitalization, need for invasive ventilation, Intensive Care Unit admission, clinical outcome and High-Resolution Computed Tomography chest findings. The data was compiled on a questionnaire and analysed on SPSS 24. Result: Total 155 severe COVID-19 patients were reviewed, out of which 36 (23.2%) had mediastinal lymphadenopathy (category 1) and 119 (76.8%) had no mediastinal lymphadenopathy (category 2). Laboratory findings including median of white blood cells and lymphocyte percentage had no significant change in both categories. Intensive care unit admissions were 12 (33.3%) and 56 (47.1%) in category 1 and 2 respectively. Median days of hospitalization (8 days) and mortality rate (16%) were almost the same in both categories. Conclusion: Our study concludes that presence of mediastinal lymphadenopathy in severe COVID-19 cases is not associated with worse outcome. However, overall prevalence of mediastinal lymphadenopathy in severe cases is high (23.2%).

Background: Antibiotic resistance is on an increasing trend, particularly in gram-negative bacteria. The production of metallo Î²-lactamase (MBL) puts the health sector at great risk as it further limits the treatment option for MDR strain. MBL is mostly reported in Enterobacteriaceae, which poses resistance to almost all Î²-lactam antibiotics except monobactam. The current study aims to determine the prevalence, antibacterial sensitivity pattern, and molecular characterization of MBL in Uropathogenic E. coli from clinical samples of hospitalized patients in Khyber Pakhtunkhwa. Methods: From tertiary care hospitals in Peshawar, 250 Urine samples were collected from indoor hospitalized patients. Gold standard microbiological methods were used to identify UPEC from these clinical samples.For that,urine samples was inoculated onto Cysteine Lactose Electrolyte. Deficient (CLED) agar plate, and MacConkey Agar.Positive growth of E.coli identified through Gram staining, colony morphology, Biochemical Tests and E.coli 16srRNA gene amplification .Antibiotic sensitivity was determined by the disc diffusion method on Muller Hinton agar. For the detection of MBL production double disc synergy, and a combination disc test of the antibiotics were used. Furthermore, multiplex PCR was used for the molecular characterization of the MBL (blaIMP, blaVIM, and blaNDM) genes. Results: Of the 250 samples, only 110 samples were confirmed as Uropathogenic E. coli based on colonial morphology, biochemical testing, and molecular level by targeting the 16SrDNA. Female was found more susceptible to UTI compared to male. High prevalence was found in the age group 45-65 years. UPEC was found highly resistance to Ciprofloxacin (90%), followed by Cefotaxime and Ceftriaxone (86%), Ceftazidime and Augmentin (81%), Tazobactam (61%). while the lowest resistance was reported against Meropenum (20%) Imipenem (18%) and Amikacin (37%). PCR-based confirmed prevalence of MBL encoding genes was blaNDM (42%), blaVIM (32%), and blaIMP (26%). Conclusion: The study proposed a higher prevalence of urinary tract infections (UTIs) in females aged group 54-65 years compared to males. An analysis of antibiotic sensitivity revealed Imipenem and Meropenem to be the most effective antimicrobial agents, while Ciprofloxacin, Cefotaxime and Amoxicillin were found to be the less effective. UPEC were found highly resistance to Ciprofloxacin 91%, and ceftazidime 86%, while comparatively less resistance to meropenem, and imipenem,20% and 18% respectively. Genotype BlaNDM of the MBL is highly prevalent (42%) among UPEC.Furthermore, the presence of MBL genes was detected in over 19% of UPEC, and in different combinations.The upraise of the MBLs resistance in uropathogenic E. coli is an alarming sign for clinicians to decide on treatment options for complicated UTIs.

Authors: Khandolkar Teja , Desai Purva Hegde , Mekoth Nandakumar , Borde Nilesh 
Published: December 2024

Objective of the study: This research paper aims to develop a conceptual framework based on an extensive literature review in the area of social media communication (SMC) consisting of Firm Generated Content (FGC) and User Generated Content (UGC) to unearth their influences on social media brand engagement (SMBE) and customer-based brand equity (CBBE). The role played by perceived risk is also highlighted.
Methodology/approach: This study has critically evaluated the literature to propose the conceptual framework using 101 research articles from 1974 to 2023 that directly or indirectly comprised at least one of the constructs.
Main results: This literature review found contradictory results regarding which source is more credible on social media, the firm or the user. This empirical gap is firstly deliberated. Secondly, the disparity on whether engagement drives equity or equity drives engagement on social media led to the conceptual gap. The conceptual model is formulated based on this debate.
Theoretical/methodological contributions: While the independent constructs are drawn from the elaboration likelihood model and source credibility theory, the mediating role of SMBE is posited based on the social identity theory.
Relevance/originality: In the context of social media, this conceptual model highlights the mediating effect of brand engagement and the moderating effect of perceived risk between social media communication and CBBE. The influence of mediation and moderation could explain the path to CBBE more explicitly.

Published: December 2024

оптимизация портфеля представляет собой задачу многомерного характера, где необходимо учитывать различные критерии, такие как минимизация риска, достижение целевого уровня доходности и обеспечение диверсификации активов. В исследовании использован подход, основанный на минимизации стандартного отклонения доходности портфеля при заданных ограничениях на доли активов, что предотвращает чрезмерную концентрацию капитала на одном активе. Особое внимание уделяется использованию энтропийного показателя для оценки степени диверсификации, что позволяет равномерно распределять капитал среди активов и снижать концентрационные риски. Для оценки риска портфеля используется ковариационная матрица доходностей активов, что позволяет более точно учесть корреляции между активами. В результате были получены оптимальные портфели, характеризующиеся приемлемым уровнем риска и доходности. Представленные результаты показывают, что методы нелинейного программирования обеспечивают эффективное решение задач портфельной оптимизации, минимизируя риски и обеспечивая устойчивость к рыночным колебаниям. Исследование подчеркивает важность интеграции показателей диверсификации и риска для создания сбалансированных инвестиционных портфелей, что делает предложенный подход полезным для практического применения в управлении активами.
portfolio optimization is a multidimensional task that requires considering multiple criteria, such as risk minimization, achieving a target return level, and ensuring asset diversification. The study employs an approach based on minimizing portfolio return volatility under constraints on asset shares, preventing excessive concentration of capital in a single asset. Special attention is given to the use of an entropy measure to evaluate the degree of diversification, allowing for balanced capital allocation among assets and reducing concentration risks. The portfolio's risk is assessed using a covariance matrix of asset returns, which more accurately captures the correlations between assets. The results demonstrate optimal portfolios characterized by acceptable levels of risk and return. The findings indicate that nonlinear programming methods provide an effective solution for portfolio optimization, minimizing risks and ensuring resilience to market fluctuations. The study highlights the importance of integrating diversification and risk measures to create balanced investment portfolios, making the proposed approach valuable for practical asset management applications.
