Fabrication of nanoporous au-ag thin films using magnetron sputtering deposition and etching process
Authors: Bui Thi Phuong Quynh
Published: December 2024

The hierarchical nanoporous structure is often described as a corrosion-derived, bi-continuous porous network of interconnected ligaments. Nanoporous metallic materials have attracted much interest as they hold great potential for advanced applications in various areas. In this study, nanoporous Au-Ag thin films were formed on the n-doped Si (110) wafers, using magnetron sputtering deposition and subsequent electrochemical etching in HF solution. The etched Au0.12Ag0.23Si0.65 film had a highly rough surface, including ligaments in sizes of 30-40 nm and small pore channels with cross sizes of 10-30 nm on SEM analysis. AES depth profiling data showed that Ag atoms tended to distribute more on the surface than underlying regions after the dealloying process. The thicknesses of films before and after etching were approximately 150 nm and 100 nm, respectively. The nanoporous film exhibited a significant current response toward the electrochemical oxidation of phenol at 0.7 V. The results indicate that the as-fabricated nanoporous Au-Ag structure with the mentioned characteristics can be studied further for potential applications in chemical and biochemical areas.

Authors: Jatin Navani
Published: December 2024

The efficient market theory suggests that the 'buy and hold' (B&H) strategy is optimal due to its simplicity and lower costs. Artificial intelligence (AI) models, including machine learning (ML) is now a common research tool in financial applications. However, advancements in AI and machine learning offer the potential to outperform B&H. This paper investigates AI models applied to the Nifty 50 index, demonstrating that an AI-based strategy can surpass the performance of the traditional B&H approach. We compare various machine learning classifiers, such as LightGBM, KNN, XGB, SVC, and Random Forest, to evaluate their effectiveness. Additionally, we dive into the feature engineering process, converting a core set of financial indicators into comprehensive datasets for model training. A detailed Profit and Loss (PnL) comparison is conducted, revealing that our AI-based strategy not only outperforms the B&H strategy in general but also shows resilience during volatile market conditions. The findings highlights the significant potential of AI in developing superior trading strategies, offering insights into its practical applications in financial markets.

Published: December 2024

Background

The complex nature of musculoskeletal diseases and the limitations of existing treatments have driven researchers to explore innovative solutions, particularly those involving stem cells and their derivatives. The utilization of the IPFP as a source of MSC-derived non-cellular products for the treatment of musculoskeletal diseases has gained recognition in recent years. This study aimed to identify the progress of IPFP-derived acellular biologics use in the treatment of orthopedic conditions such as osteoarthritis and ligament and/or tendon injuries.

Methods

A literature search was conducted through PubMed, Scopus and Google Scholar databases including studies over the past 10 years. This scoping review includes studies discussing the development of intercellular messenger signaling molecules (non-cellular products) in the form of exosomes, secretomes, and conditioned medium derived from the IPFP in the management of musculoskeletal diseases. The PRISMA-ScR guidelines were utilized in this review.

Results

Six studies met the inclusion criteria. Most studies reported the beneficial anti-inflammatory effects of IPFP-derived noncellular products in musculoskeletal conditions. The effects of IPFP-derived exosomes, secretomes, and conditioned medium administration are mostly reported in microscopic changes through cellular and matrix changes. Additionally, quantitative analyses involved assessing levels of anti-inflammatory and pro-inflammatory markers, proteins, fatty acids, and gene expression.

Conclusions

The use of IPFP-derived non-cellular products has shown significant promise in the regenerative therapy for musculoskeletal diseases. These agents have demonstrated beneficial effects, particularly in reducing inflammation, promoting cellular changes, and enhancing tissue regeneration. However, further research is needed to fully understand the characteristics and explore the potential applications of IPFP-derived non-cellular products in musculoskeletal cases.

Authors: Atrushi Akrem M. , Armishty Farhad Shaker , Saleh Sirwan A. , Abdulrahman Mehvan Sh.
Published: December 2024

Backgrounds: Obesity among children is a global health issue, with a significant increase in prevalence over the past three decades. Over 379 million children and adolescents globally are overweight or obese. Magnesium is fourth among the most abundant cations after calcium, sodium, and potassium. Magnesium is essential for biological functions. It can lead to deadly outcomes such as vasospasm of cardiac arteries, arrhythmias, and even unexpected death. Methodology: A cross-sectional case-control research design was used to evaluate data from 100 children 50 boys, and 50 girls, aged 2-14 years at Zakho General Hospital in Iraq. The sample was obtained between April 1st, 2022, and April 1st, 2023. Demographic data, blood collection, and anthropometric measurements were used. Serum magnesium levels were measured and body mass index (BMI) was calculated. Ethical approval was obtained from the College of Medicine/University of Zakho. Statistical analysis included Chi-square and independent t-tests. Results: The study found that the majority of obese children are 5-10 years old, with males dominating.  The mean serum magnesium level for all participants was 2.082 ±0.190 mg/dl which is a bit higher in the obese than normal-weight children with no significant difference. Conclusion: The serum magnesium level is not significantly related to body weight in children. Further studies are recommended focusing on the dietary intake and physical activity that are the main confounders for this association.

Corrosion inhibitors are widely used in industry to reduce the corrosion rate of metals and alloys. Corrosion inhibitors adsorb onto metallic surfaces and insulate them from deterioration. Plants abundant in nature offer a cost-effective replacement for toxic chemical inhibitors on the market. The current research used the potentiostatic polarization technique at room temperature to explore the inhibitory impact of water hyacinth extract on the corrosion of low-carbon steel specimens in a 3.5% NaCl solution. The Tafel curve was used to assess corrosion inhibition activity, with the best inhibition efficiency reaching 79.36% at a concentration of 200 ppm. Cyclic polarization indicated the type of corrosion was general corrosion. The surface of carbon steel was investigated using Scanning Electron Microscopy (SEM) and Fourier Transform Infrared Spectroscopy (FTIR). FTIR analysis reveals the presence of alkaloid compounds, which are known corrosion inhibitors. In addition, the polarization behavior indicates that this inhibitor acts as a mixed-type inhibitor. Kinetic and thermodynamic parameters have been obtained from temperature studies. The higher activation energy than the blank (26.17 kJ/mol to 46.4 kJ/mol) suggests that an inhibitor has been deposited on the metal surface that is corroding, providing a resist layer to prevent corrosion. The low-carbon steel dissolution process is exothermic, as evidenced by the negative enthalpy of activation value. A positive increase in the activation entropy during the formation of the film layer suggests more disordering.

Published: December 2024

Both humoral and cell-mediated immune responses are among the many immunological processes that are impacted by cigarette smoking in both humans and experimental animals. The purpose of this study was to determine the consequences of smoking by estimating the blood level of IL-6, an inflammatory biomarker, in cigarette smokers. 49 blood samples taken from healthy students at Qadisiyah University between November 2017 and February 2018 were used in this study to measure the concentration of IL-6 serum level. Using the ELISA technique (Sandwich ELISA formate), the chosen samples were divided into two groups: the first group consisted of twenty healthy, non-smoking students, while the second group consisted of twenty-nine smoking students. The results indicated that the patients' blood levels of IL-6 were considerably lower (46.4 pg/ml) than those of healthy individuals (96.1 pg/ml). In conclusion, the smoking group showed a drop in serum IL-6 content, which clarified the smokers' vulnerability to infection by a number of illnesses, particularly respiratory tract infections.
Analysing Career Interests Among Middle And High School Students In Kuwait: Implications For Early Career Planning
Authors: Fouzan Aseel Al
Published: December 2024

This research investigates the career preferences of middle and high school students in Kuwait, focusing on the impact of early career guidance. The main concern is the absence of organized career counseling in schools, which often results in confusion and poor alignment between students' aspirations and their actual career choices. A significant number of students face difficulties in making well-informed decisions regarding their future careers due to a lack of exposure to various professions. These choices are frequently shaped by societal pressures and family expectations. The study's primary goals are to examine students' career interests, identify the factors that shape these interests, and assess the role of early career advice in guiding their career decisions. The research involved a sample of 350 students from middle and high schools across Kuwait, selected randomly. Data were collected through structured surveys and analyzed using SPSS, with additional qualitative insights included for a more comprehensive understanding. The findings show that societal influences, family expectations, and the prestige of professions like medicine, engineering, and education play a major role in students' career interests. A lack of exposure to a broad range of career options often limits students' ability to make fully informed decisions. Based on these results, the study suggests introducing formal career counseling programs in schools to offer students the opportunity to explore a wider array of career possibilities. Providing early guidance and access to various career paths could significantly improve decision-making, helping students make choices that align with their abilities and interests, leading to greater long-term satisfaction in their professional lives.

Published: December 2024

This research examines the implementation of the 30% women's representation quota policy in Indonesian politics. Using a qualitative method with a descriptive analytical approach through library research, this study analyzes the challenges and effectiveness of affirmative action policies for women in politics. The findings show that despite the quota policy, women's representation in legislative bodies remains inadequate due to several factors, including patriarchal culture, limited access to political education, and varying levels of political party commitment. The study reveals that patriarchal social systems tend to position men in higher public roles while women are expected to focus on domestic roles, leading to detrimental stereotypes that reduce women's interest and confidence in political participation. Additionally, women face internal challenges such as limited political experience and knowledge due to restricted access to political education and training. Political parties' varying commitment to affirmative policies further compounds these challenges, with some parties merely fulfilling the 30% quota as an administrative requirement. This study recommends comprehensive measures including enhanced political education for women, gender equality awareness programs, strengthened support from political parties, and systemic changes in social and political structures to achieve more effective women's representation in Indonesian politics.

Published: December 2024

Background: Medication errors are a significant issue in healthcare, especially in emergency neonatal care, where infants are particularly vulnerable due to their unique physiological characteristics and the complexity of drug management. This systematic review explores the roles of advanced practice nurses (APNs) and clinical pharmacists in reducing medication errors in this high-risk environment. Methods: A comprehensive search of PubMed and EMBASE was conducted for studies published from 1966 to 2018, focusing on interventions aimed at minimizing medication errors in neonatal care. Results: The review identified 86 comparative studies, revealing varied methodologies and outcomes. Notably, while no single intervention emerged as the most effective, multifaceted strategies incorporating both technology and clinical expertise demonstrated promise in enhancing medication safety. Advanced practice nurses and clinical pharmacists were found to significantly contribute to reducing medication errors through direct involvement in prescribing, monitoring, and patient education. Despite the positive findings, the review highlighted the need for standardized methodologies and consistent reporting criteria across studies to draw definitive conclusions. Conclusions: The findings underscore the importance of integrating APNs and clinical pharmacists into neonatal care teams to mitigate medication errors and improve patient safety.

Cervical insufficiency, a condition marked by premature cervical dilation, poses a significant risk for preterm birth and second-trimester pregnancy loss. This review systematically evaluates the effectiveness of cervical cerclage and its alternatives in managing cervical insufficiency to improve perinatal outcomes. The study’s objective is to analyze various techniques, including single and double cerclage, elective versus emergency interventions, and non-surgical alternatives such as the cervical pessary and vaginal progesterone. A systematic literature review was conducted using databases such as PubMed, Scopus, and Embase, focusing on studies from the last 10 years. Of the 50 articles reviewed, 26 met the inclusion criteria and provided quantitative or qualitative data on perinatal outcomes and complications. The findings underscore the importance of personalized intervention methods, revealing that certain techniques may be more effective in high-risk populations. This review contributes to both clinical and theoretical discussions, emphasizing early intervention and tailored treatment plans. Further research should include diverse populations and examine long-term neonatal outcomes. Limitations of the study include potential selection bias and language restrictions.
The Evolution of Privacy and Abortion Rights: A Comparative Legal Analysis of The United States and The European Union
Authors: Dai Xinhui
Published: December 2024

The legal frameworks governing abortion rights have seen profound shifts in both the United States and the European Union, shaped by contrasting principles of constitutional law and human rights law. In the U.S., abortion was historically protected under the 14th Amendment’s right to privacy, as established in Roe v. Wade in 1973. This precedent was later modified by the undue burden test from Planned Parenthood v. Casey in 1992, which allowed states to regulate abortion as long as no substantial obstacles were placed on a woman seeking the procedure. However, the recent Dobbs v. Jackson Women’s Health Organization in 2022 ruling overturned Roe, giving individual states the authority to legislate abortion access, resulting in a highly polarized and fragmented legal landscape. In contrast, the EU regulates abortion through a human rights-based approach, under Article 8 of the European Convention on Human Rights, which guarantees the right to private and family life. The margin of appreciation doctrine, employed by the European Court of Human Rights, grants EU member states discretion to regulate abortion based on cultural, moral, and religious norms, leading to significant variation in abortion laws across Europe. This paper undertakes a comparative legal analysis of the U.S. and EU approaches to abortion, examining the evolution of privacy and human rights frameworks. It further explores the practical implications of these legal systems, focusing on access to abortion and the impact on vulnerable populations. The analysis also considers the future legislative trends in both regions, with attention to the political forces shaping potential reforms.
