Authors: Desai Dr. Arpitaben P. , K Patel Drashti
Published: December 2023

To investigate the in vitro antibacterial activity of these chalcones against Gram-positive and Gram- negative bacteria as well as fungi, a series of five chalcones that closely mimic those found in nature were created. By the Claisen-Schmidt condensation and a green chemistry procedure that used sodium hydroxide as a catalyst in clean water, chalcones were produced from acetophenone and substituted benzaldehydes with good yields. Amoxicillin and fluconazole were used as standards for the antimicrobial assessment, which was done using the filter paper disc plate technique on a set of chosen bacteria. The structure of the generated derivatives has been determined by employing FTIR Spectroscopy, NMR, and other physicochemical characteristics. These synthesized chalcones showed the expected antibacterial action after being tested for it. This green procedure is the most practical, effective, and environmentally friendly method for the synthesis of chalcones by the Claisen- Schmidt condensation because it is simple to synthesize and purify these chalcones and because high yields are observed. The future development of chalcone derivatives as commercial antibacterial medicines is quite promising.

Authors: Nithin Karanam , Manoj Vasupalli , Mohith Budumuru
Published: December 2023

A fuel-cell hybrid electric vehicle is an advanced type of hybrid vehicle that utilizes a combination of fuel-cell technology and electric propulsion for improved efficiency. The fuel cell generates electricity through a chemical reaction using hydrogen as the fuel source. This electricity powers the vehicle’s electric motor, while a battery system stores excess energy, provides additional power during acceleration, and stores regenerative braking energy. To improve the performance of fuel cell hybrids, designing and developing efficient energy management strategies is an urgent need for current automotive manufacturers. From the perspective of energy consumption, the main work is to reduce hydrogen consumption. In recent years, energy management strategies based on intelligent connected vehicle technology have also received extensive attention. Most fuel cell vehicles are classified as zero- emission vehicles that emit only water and heat. Compared with internal combustion vehicles, hydrogen vehicles centralize pollutants at the site of hydrogen production. In an electric drive vehicle, the low-voltage auxiliary battery provides electricity to start the engine before the traction battery is engaged, it also powers vehicle accessories. This high-voltage battery stores energy from regenerative braking and provides supplemental power to the electric motor. The DC converter converts higher voltage to lower voltage DC power which is needed to run the vehicle and recharge the auxiliary battery. Using power from the fuel cell and the traction battery pack, the motor drives the vehicle’s wheels. A fuel cell stack is an assembly of individual membrane electrodes that use hydrogen and oxygen to produce electricity. So the fuel cell electric vehicle is the best option to simultaneously reduce air pollution, greenhouse gas emissions, and the consumption of fossil fuels Key Words: Battery(auxiliary), Battery pack such as petroleum and natural gas., DC/DC Converter, Electric traction motor(FCEV), Fuel cell stack, Fuel filler, Fuel tank(hydrogen), Power electronics controller, Thermal system(cooling), Transmission(electric)

The aim of the present research is to evaluate the way that albino rats administered with a high-protein diet, react to methanolic root extracts of Lagerstroemia speciosa anticalciuric properties. Medicinal plants are frequently utilised in folk medicine to treat a wide range of illnesses. Banaba is the common name for L. speciosa, a member of the Lythraceae family; Poomaruthu is its Tamil name. The test animals were given a diet high in protein and low in protein as well as 45 days of treatment with methanolic root extracts of L. speciosa. The experiment was scheduled with a sample collection, biochemical inquiries, and histopathological exams. The experiment had been scheduled with a sample collection, biochemical investigations, and histopathological evaluations. The biochemical data reveal that as compared to the control, III, and V groups, the low-protein diet groups II and IV had greater blood urea concentrations. The low-protein diet groups II and IV exhibited an increased blood creatinine concentration in contrast to the control, III, and V groups, while group V (H.P+MRE 500 mg/kg) demonstrated a nearly identical outcome to that of the control groups. L. speciosa root extracts in methanol are given to groups to control creatinine concentration. The normal control group's histopathological analysis revealed tubules with a single epithelial lining along the outermost layer that were normal in size.

Published: December 2023

Active learning is increasingly recognized as a cornerstone of higher education's teaching-learning paradigm. In this context, educators serve as facilitators, empowering students to take the lead and assume co-responsibility for their learning. Among the array of active learning strategies available, the portfolio stands out as an instrument that not only aids in knowledge construction but also fosters the development of crucial skills like autonomy and creativity. Furthermore, it serves as an interactive and participatory learning approach that encourages self-assessment and reflection on the teaching-learning journey. Portfolios, through the continual (re)construction of knowledge and ongoing collaborative engagement between students and educators, promote self-regulated learning by progressively fostering students' awareness of their learning process. This study reflects on the pedagogical application of individual portfolios, aiming to explore their role in enhancing writing skills within a digital context and nurturing cross-disciplinary skills highly valued by employers. Specifically, it delves into students' perceptions of the portfolio construction process within the Internet Writing course, a segment of the Master's degree program in Marketing and Digital Communication at the University of Aveiro (Portugal). After a brief examination of active learning strategies, with a specific emphasis on portfolios as tools for self-reflection and learning, the study analyzes questionnaire survey results utilizing SPSS software.

Authors: Alhajri Thafar M , Alshebli Abdullah
Published: December 2023

Objective: The objective of the article is to trace the historical development of laws relating to trading in securities in countries whose legal system is based on Shariah law and Islamic law principles.  Countries such as Saudi Arabia, Kuwait and Qatar base their legal systems on Shariah law but have had to develop their financial markets and stock exchanges in a way that attracts foreign investors and stimulates economic growth. This article sets out how the various legal systems have developed in response to differing circumstances in each country.

 

Method: The authors used a study-analysis method in preparing this article. The article is styled as a historical research paper based on the extensive research and expert opinion of the authors. For the theoretical framework the authors used a comparative legal analysis of the laws enacted by different countries to highlight the different approaches taken in response to financial scandals and abuses. It will show that despite having a common legal framework based on Shariah law, each country has developed at its own pace and in response to its own circumstances.

 

Result: The article highlights the different approaches taken by different countries when enacting laws regulating financial markets and stock exchanges, even though they are based on Shariah law and Islamic legal principles. The article highlights the value of Islamic Law in some instances but also shows that there is no one-size-fits-all approach that can be taken. This article addresses the problems associated with a lack of regulation of financial markets and rapid growth in economic activity in the GCC countries, and how lawmakers have responded to these challenges.

 

Conclusion: The article is unique in its study of various modern laws enacted by countries that apply Sharia law. This article sets out how legal systems based on Shariah law can still develop efficient financial markets and stock exchanges but highlights how the lack of regulation can lead to abuse and financial scandals.

Male Breast Cancer (MBC) – A Review
Authors: AlFehaid Mohammed
Published: December 2023

Males account for 1% of all cases of breast cancer. With the aging of the world’s population, the disease has exhibited a rise in incidence in recent decades. Male breasts are smaller than female breasts, making the disease easier to spot, but patients often do not report their cases in time due to a lack of awareness. The stage-to-stage prognosis of male breast cancer is comparable to that of their female counterparts. Due to the relative rarity of the disease and poor patient enrollment in large randomized studies, the optimal management of male breast cancer remains uncertain. This article presents a narrative review of male breast cancer in light of recent literature, with an emphasis on epidemiology, clinical features, and current management.

Authors: Zaremba Łukasz
Published: December 2023

The aim of the study was to identify factors influencing the variability of purchase prices of vegetables: onions, carrots and cabbage intended for direct consumption and processing. The research period covered years 2011-2022. The article analyzes the variability of purchase prices. It was found that its level in case of the vegetables, taken into consideration, was relatively high, with a slight downward trend in 2020-2022. The prices of vegetables for direct consumption were more volatile than those of vegetables intended for processing. The identification of factors influencing changes in purchase prices was based on the analysis of correlations between purchase prices and time series of selected variables on an annual basis. The study took into account the production volume, the level of import and export of fresh vegetables including processed vegetables, changes in the prices of plant protection products, manual labor fees, fertilizer prices and diesel oil prices. It was found that the strongest correlation occurred between purchase prices and prices of fertilizers, as well as plant protection products. Due to the relatively short research period, it was not possible to determine the correlation between prices and harvest levels. Then, Granger causality tests of selected factors were performed on a monthly basis. The impact of changes in the level of import and export, as well as the prices of plant protection products and manual labor fees on the prices of most products included in the study was confirmed.

Published: December 2023

Background: This study aims to evaluate surgical outcomes and prognosis in patients who underwent extended lung resection for locally advanced lung cancer.

Methods: Between January 2015 and December 2019, a total of 61 patients (60 males, 1 female; mean age: 61.7±12.2 years; range, 32 to 90 years) with locally advanced non-small-cell lung cancer who underwent extended lung resection were retrospectively analyzed. Data including age, sex, comorbid diseases, symptoms, smoking status, pulmonary function test results, tumor location, methods used for preoperative tissue diagnosis, histopathological cell type, type of surgical resection, pathological stage, nodal involvement, postoperative complications, types of adjuvant therapy, and mortality rate were recorded. Survival and the factors affecting survival were examined.

Results: Seven (11.4%) patients had Stage IIIB, 40 (65.5%) patients had Stage IIIA, and 14 (22.9%) patients had Stage IB disease. Intrapericardial pneumonectomy accounted for 30 (49.1%) of all extended lung resections. Chemotherapy was administered to 31 (50.8%) patients and chemoradiotherapy to 24 (39.3%) patients in the postoperative period. In the survival analysis, 70-month survival rate was calculated as 63.9% and the median survival was 48 months. There was a statistically significant association between survival with adjuvant chemotherapy and chemoradiotherapy (p=0.003). The mortality rate at 70 months of follow-up was 36.1%.

Conclusion: Extended lung resection contributes significantly to the improvement of survival rates in carefully selected locally advanced cases. Particularly with adjuvant chemotherapy, local recurrences can be prevented, and survival rates can be improved.

Background: This study aims to investigate the effect of large proximal aortic neck diameter on post-endovascular aneurysm repair clinical outcomes.

Methods: A total of 180 patients (168 males, 12 females; mean age: 69.9±7.4 years; range, 46 to 88 years) who underwent elective endovascular aneurysm repair between June 2016 and September 2021 were retrospectively analyzed. According to the proximal infrarenal aortic neck diameter, the patients were divided into two groups: Group 1 (<25 mm; normal aortic neck) and Group 2 (≥25 mm; pre-aneurysmatic aortic neck). Patient characteristics, proximal infrarenal aortic neck diameter measurements with computed tomography angiography, and clinical outcomes were recorded. The primary endpoint was to assess post-endovascular aneurysm repair aortic neck dilatation, mortality, endoleaks, overall survival, type 1a endoleaks-free survival, and eventfree survival regarding the groups.

Results: There was no statistically significant difference in early mortality (p=0.55) and type 1a endoleak incidence between the groups (p=0.55). In Group 1, the mean change in diameter A (proximal infrarenal level) was 2.89±1.74 mm (p=0.01), and it was 2.31±2.1 mm in diameter B (proximal pre-aneurysm-sac level) (p=0.01). The mean change in Group 2 was 2.8±3.4 mm for diameter A (p<0.01) and 2.22±2.3 mm for diameter B (p<0.01). Aortic neck dilatation rates were similar between the groups (p=0.82 for diameter A; p=0.78 for diameter B). The five-year survival, event-free survival, and type 1a endoleak-free survival were also similar (p=0.54, p=0.26, p=0.24, respectively).

Conclusion: Our study results showed that patients with <25 mm and ≥25-mm aortic neck diameters had similar mid-term results and aortic neck dilatation ratio. Endovascular aneurysm repair outcomes can be improved with careful patient and graft selection, and early intervention for complications.

Published: December 2023

Background: This study aimed to compare the outcomes of minimally invasive mitral valve surgery and conventional surgery in terms of mortality and postoperative complications.

Methods: A retrospective analysis was conducted on consecutive minimally invasive and conventional mitral valve surgeries performed between January 2019 and December 2022. Patients undergoing concomitant procedures were excluded from the study, and 293 patients (149 females, 144 males; mean age: 53.8±12.9 years; range, 18 to 82 years) were included in the study. Of these patients, 96 underwent minimally invasive surgery (MI group), and 197 underwent mitral valve surgery via conventional sternotomy (CS group). Propensity score matching was utilized to minimize the biases and confounding factors. After propensity score matching, 55 patients were included in each group.

Results: There was no statistically significant difference in terms of mortality between the propensity score-matched groups (p=0.315), and no statistically significant difference in postoperative complications was observed between the groups. However, it was found that postoperative new-onset atrial fibrillation was lower in the minimally invasive group (p=0.022).

Conclusion: This study demonstrates that minimally invasive mitral valve surgery is a safe alternative with similar mortality and postoperative complication rates compared to conventional surgery. Additionally, the study suggests an association between minimally invasive surgery and postoperative new onset atrial fibrillation.

A cardiomiopatia hipertrófica (CMH) é uma patologia cardíaca de origem genética que possui, como traço característico, a alteração conformacional das fibras constituintes do miocárdio. Essa alteração é tida como fator de origem do principal fenótipo anatômico expresso pela supracitada doença, a hipertrofia ventricular, a qual é apresentada mais intensamente, na área da cavidade cardíaca ventricular esquerda e no septo interventricular. O presente relato de caso abordará a doença por meio de 4 casos de CMH em pacientes infanto juvenis atendidos no estado do Amapá no ano de 2023, dentre os quais, possui maior destaque o caso de associação entre essa anomalia cardíaca com a síndrome de Berardinelli-Seip (SBS), alteração que resulta na quase completa ausência de tecido adiposo.

Dalam Hubungan Internasional, aktor tidak hanya terbatas pada negara dan birokrasinya (government), tetapi telah melampaui peran pemerintah (governance). Tuntutan dalam pencapaian pembangunan berkelanjutan dalam berbagai sektor terus diharapkan untuk segera dipenuhi sehingga berbagai perusahaan multi-sektor memiliki tanggung jawab sosial untuk menangani masalah-masalah yang mendasar tersebut. Oleh karena itu, penelitian ini bertujuan untuk menyelidiki bagaimana Corporate Social Responsibility (CSR) dilakukan pada salah satu bisnis minyak dan gas terbesar di Kalimantan Timur terutama dalam bidang pendidikan. Adapun beberapa hal yang peneliti analisis adalah kegiatan dan proses apa saja yang digunakan oleh perusahaan ini untuk mengembangkan program CSR. Metode penelitian yang diterapkan pada penelitian ini adalah kualitatif dengan menggunakan metode wawancara semi-terstruktur pada tiga orang yang bertugas pada pelaksanaan program. Mereka berperan dalam perancangan kegiatan CSR pada perusahaan. Penelitian ini menemukan beberapa hasil, yaitu: program CSR yang dijalankan oleh perusahaan tersebut mengikuti pedoman Tata Kelola Perusahaan yang Baik (Good Corporate Governance), salah satunya dalam bidang pendidikan. Di dalam program tersebut, terdapat lima kegiatan bidang pendidikan yang dijalankan untuk memenuhi program tujuan pembangunan berkelanjutan ke-4, yaitu pendidikan berkualitas. Program yang dijalankan masih berupa pemberian donasi atau charity dan kegiatan volunteer kepada stakeholder, karena program CSR merupakan bagian dari profit dan perusahaan belum mendapatkan laba sebab masih dalam tahap pembangunan, sehingga perusahaan belum melaksanakan program CSR yang bersifat berkelanjutan. Selain itu, terdapat beberapa saran untuk penelitian selanjutnya pada CSR yang dapat dilakukan oleh perusahaan tersebut, yaitu diharapkan kegiatan CSR tetap terus berlanjut dan meningkatkan kualitas program menjadi sustainable bagi stakeholder.

Fused deposition modeling (FDM) is a technology with potential benefits such as material versatility, user-friendliness, and cost-effectiveness. However, the mechanical properties of FDM-printed specimens are relatively low. To address this issue, post-processing techniques such as shot peening can be employed. Shot peening is utilized as a post-treatment for metal-based and ABS materials, but its application to PLA material has not been explored yet. This study aimed to evaluate the effect of shot peening on the mechanical properties of FDM-printed PLA samples. A full factorial experimental design was employed with shot peening speed, duration, and number of outer shells as parameters. The tensile strength of 72 samples after the shot peening process was measured and evaluated. Analysis of variance (ANOVA) revealed that all parameters had a significant influence on tensile strength. Additionally, the interaction of speed*time and speed*number of shells also had a significant influence. Meanwhile, the interaction of time*number of shells and speed*time*number of shells had no significant influence. The findings of this study demonstrate the potential of post-processing techniques to enhance the mechanical strength of FDM components, particularly those composed of PLA material.

Authors: Hobjilă Angelica
Published: December 2023

. In contemporary society, given the ever-increasing place it occupies, from the earliest ages, media and technology in children’s lives, a coherent and responsible approach is required to familiarize them with the implications of the information disseminated, with emphasis on receiving and decoding messages transmitted by media, on differentiating false / misleading / manipulative information, on critical reporting on messages, etc. In this context, the objective of this article is to identify references to media literacy in two types of documents: (a) the compulsory curriculum for primary school, in Romania; (b) lists of activities that schools (from urban and rural areas) in Romania have proposed for the “School differently” program. The identified elements will represent premises for analyses and projections at the primary school level, regarding both the exploitation of data from the compulsory curriculum, and the design of activities that involve media literacy.
