LGBT psychology and feminist psychology: Bridging the divide
Authors: Clarke Victoria , Peel Elizabeth
Published: October 2024

In this paper, we outline some of the similarities and differences between lesbian and gay psychology (more recently known as LGBT psychology) and feminist psychology. Both fields developed in response to the oppressive practices of psychology; however, lesbian and gay psychologists have been far more willing to use the theoretical and methodological tools of mainstream psychology than have feminist psychologists. Feminist psychologists have enthusiastically embraced qualitative and critical approaches, whereas, until recently, lesbian and gay psychologists have been more cautious about adopting these approaches. Both feminist psychologists and lesbian and gay psychologists have debated which theories and methods best fit their goals for social change, and both have fought for and won professional recognition. Feminist psychology and lesbian and gay psychology have remained largely distinct from each other; however, there have been some encouraging signs of late – including this Special Issue – that suggest the gap between these two fields may be lessening.

Published: October 2024

Hydrogen liquefaction is an essential process in cryogenics, facilitating the efficient storage and transport of hydrogen as a clean energy carrier. This study investigates the liquefaction of hydrogen at a flow rate of 100 kmol/h, with an energy consumption of 447.05 kW. The process relies on sophisticated equipment, including multi-stage compressors and expansion devices, which play key roles in cooling and compressing the hydrogen gas. One of the notable advantages of this system is the energy recovery achieved by an expansion device, which generates 262.1 kW, enhancing overall efficiency.The hydrogen compression stages use a multi-stage compressor that employs water as the primary coolant. With a flow rate of 389.4 kmol/h, water is chosen due to its high specific heat capacity and availability, making it an ideal coolant for this cryogenic process. Ethane, serving as a secondary refrigerant, operates at a flow rate of 32 kmol/h. Its non-corrosive and inert properties contribute to system durability, while a portion of the ethane is strategically recycled through heat exchangers to minimize consumption and optimize cooling efficiency. Hydrogen enters the system at 5×10⁵ Pa and 288 K, and is gradually cooled and compressed to 2×10⁵ Pa and 22.75 K, resulting in the final liquid hydrogen product. This significant temperature reduction, achieved through the combined cooling effects of water and ethane, is critical for the successful liquefaction of hydrogen. The optimized use of refrigerants and efficient energy recovery in the expansion stages reduce operational costs and enhance process sustainability.

A técnica é um elemento essencial para a ação humana. Em áreas que aliam ensino e formação, como é o caso da Educação Física, o componente técnico recebeu influências de distintas concepções, de modo que se faz presente na área de forma assimilada ou crítica. Desse modo, o presente texto tem como objetivo analisar o papel da técnica na Educação Física sob o ponto de vista teórico, a partir da contribuição de Álvaro Vieira Pinto. A concepção de técnica desse autor assenta-se na observação dialética da técnica enquanto momento intermediário que é animado e perpassado por uma dada concepção de homem e mundo – consubstanciando, portanto, uma natureza socioaxiológica e processual – que se objetiva num dado modo de produção e cooperação. Nessa perspectiva é possível romper com o caráter tecnicista do ensino, aliando a prática com a contextualização sócio-histórica do conteúdo que se pretende ensinar. Parece válido, assim, operar uma aproximação inicial à filosofia da tecnologia de Álvaro Vieira Pinto; filosofia esta que se mostra um terreno fértil para a reflexão crítica acerca da significação da técnica no âmbito da Educação Física Escolar.

Authors:   Burlington, Ontario, Canada., Karimullah Mohamed Imteaz
Published: October 2024

In geometrical optics, in a system of two thin coaxial lenses, there are several standard formulas, including “𝟏𝑭=𝟏𝒇𝟏+𝟏𝒇𝟐−𝒅𝒇𝟏𝒇𝟐”. The purpose of this paper is to generalize these formulas to the case of a system of an arbitrary number of thin lenses. In particular, this paper proves that the focal length Fn of a system of n thin coaxial lenses is given by 𝟏𝑭𝒏=Σ{(−𝟏)𝒎Π[(Σ𝟏𝒇𝒓𝒔𝒂𝒔𝒓𝒔=𝒂𝒔−𝟏+𝟏 𝟎=𝒂𝟎<𝒂𝟏<⋯<𝑎𝒎<𝒂𝒎+𝟏=𝒏;𝒅𝒏=𝟏 )𝒅𝒂𝒔]𝒎+𝟏𝒔=𝟏}𝒏−𝟏𝒎=𝟎, where, fr is the focal length of the rth lens, and dr is the distance between the rth lens and (r+1)th lens. For a fixed value of m, all combinations of values of the a’s (satisfying the condition “0 = a0 < a1 < … < am < am+1 = n”) are taken in the inner sum.

Authors:   Department of Computer Science, Georgia Institute of Technology, Atlanta, Georgia, United States of America (USA)., Azmaien Samiel
Published: October 2024

Background Functional Neurological Disorder (FND) currently lacks a definitive method of diagnosis, leading to an extremely high rate of misdiagnosis. Methods This project aimed to address the question of improving diagnostic accuracy for FND by utilizing logistic regression models and neural networks, integrating patient MRI data and clinical history to differentiate FND from other neurological disorders. MRI scans were first pre-processed through noise reduction and feature engineering, and then used to train two types of models: logistic regression for general neurological disorder classification and a neural network specifically for FND diagnosis. The diagnostic performance was measured using the ROC AUC metric, with additional evaluation through accuracy, precision, recall, and the F1 score. Results & Conclusions By targeting the most relevant variables from the MRI data, both models demonstrated high efficacy, with the neural network showing a 92% accuracy rate in FND classification.

Authors:   Department of Pharmaceutics, Jaipur National University, Jaipur (Rajasthan), India., Gupta Kajal
Published: October 2024

The major goal of this study was to develop and test metformin sustained release tablets employing fenugreek seed mucilage (FSM) as a new binder, as opposed to standard polymers such as xanthan gum and HPMC. The study shows how FSM provides sustained medication release while keeping metformin physicochemical characteristics. The sustained-release matrix tablets were made on a laboratory scale utilizing the wet granulation process. 5 batches were created, each with varying quantities of fenugreek seed mucilage, xanthan gum, and HPMC. To examine the tablet's physical properties and consistency, different criteria such as thickness, hardness, weight variation, and content homogeneity were measured. FTIR tests were performed to determine the compatibility of metformin and the polymers employed. The results showed no incompatibility, indicating that the novel excipient, FSM was not affecting the drug's physicochemical qualities. The in-vitro drug dissolution investigation was conducted utilizing a USP type-II paddle apparatus to quantify the drug release rate from dosage forms and to assess thepolymers' efficacy in retarding drug release. The study discovered that raising the concentration ofthe matrix ingredient reduced the medication release rate. Among the formulations, the combination of FSM with HPMC (MS1) resulted in 95% drug release, FSM with xanthan gum achieved 96% drug release, and the MS4 formulation had the greatest drug release rate. Finally, the study showed that fenugreek seed mucilage and xanthan gum effectively develop metformin continuous-release matrix tablets. Lower concentrations of these polymers were more suited and effective, resulting in sustained drug release. This study demonstrates the potential of fenugreek seed mucilage as a novel and effective binder in sustained-release formulations.

Hypertension, often referred to the silent killer, is a prevalent health issue that impacts more than a billion individuals worldwide. The purpose of this study was to investigate the understanding of hypertension among Syrian individuals. 104 individuals filled out surveys. Females made up 64.4% of the group that was surveyed. 28.8% of the participants in the study were between the ages of 46 and 60. More than half of the participants had a study or a work related to the medicinal field. The participants showed good medication adherence where the score of accurate responses to the questions regarding medication compliance was very high. Most participants were familiar with the normal values of blood pressure levels and were optimistic about the possibility of treating the condition. A good percentage of individuals surveyed stated that smoking and obesity are contributing factors to developing high blood pressure. Most participants believed that consuming fatty foods raises plasma cholesterol levels. Participants had a good overall understanding of high blood pressure. However, they still need improvement in medical information about high blood pressure to enhance compliance with treatments.

Authors:   Department of Pharmaceutical Chemistry and Drug Quality Control, Faculty of Pharmacy, Al-Rachid Privet University, Damascus (Syria), West Asia., Thallaj Prof. Dr. Nasser
Published: October 2024

This thesis focuses on the development of conductive nanocomposite materials based on graphene and natural polymers such as cellulose and chitosan. Graphene, a single layer of carbon atoms arranged in a honeycomb lattice, exhibits exceptional electrical, mechanical, and thermal properties, making it an attractive filler for polymer composites. However, the challenge lies in effectively dispersing graphene sheets within polymer matrices. The work presented explores new strategies for grafting polysaccharide chains onto oxidized graphite (graphene oxide) to improve its compatibility and dispersion in cellulose and chitosan matrices. The resulting composites were doped with gold or nickel nanoparticles to further enhance their electrical and catalytic properties. Detailed characterization techniques, including spectroscopic and microscopic methods, were employed to analyze the structure, morphology, and properties of the developed nanocomposites. The thesis is organized into three main parts: 1) a literature review on graphene, polysaccharides, and their biocomposites; 2) a description of the experimental materials and methods; and 3) a scientific discussion of the results, presented in the form of three research publications. The findings demonstrate the successful synthesis of conductive nanocomposites with improved compatibility and performance, opening up new avenues for the application of these sustainable and multifunctional materials in areas such as electronics, catalysis, and electromagnetic shielding.

Recent advancements in percutaneous coronary intervention have made it a viable option, particularly for women who face unique risks and outcomes compared to men. Objective: This study aims to evaluate the characteristics and outcomes of percutaneous coronary intervention for left main stem disease in female patients, focusing on procedural outcomes and changes in laboratory parameters before and after the intervention. Methods: A prospective observational study was conducted from January to July 2024 with 68 female patients, aged 18 and above, from Fauji Foundation Hospital Rawalpindi. Various percutaneous coronary intervention techniques were used, and data on ejection fractions, access methods, and procedural specifics were collected. Pre- and post-procedural laboratory outcomes including haemoglobin, creatinine, platelet counts, and alanine aminotransferase levels were analyzed. Results: The mean age of participants was 63.6 years. Diabetes, hypertension, and dyslipidemia were common comorbidities. Laboratory results showed stable haemoglobin levels, slight increases in creatinine, and consistent platelet counts and ALT levels post-procedure. Statistical analysis revealed no significant changes in these parameters, indicating minimal impact on anaemia, renal function, and platelet or liver function. Conclusion: percutaneous coronary intervention for the left main stem in females generally results in stable laboratory outcomes with minimal impact on anaemia, renal function, and platelet or liver function. The procedure is safe with a low mortality rate. Continuous monitoring is recommended to manage any potential complications effectively.

ASSOCIATION OF SERUM ADENOSINE DEAMINASE LEVELS WITH ACUTE KIDNEY INJURY IN DIABETIC PATIENTS
Authors: USMAN M , SHAH F
Published: October 2024

Diabetes mellitus is a significant global health issue, and complications such as acute kidney injury (AKI) are prevalent in patients with type 2 diabetes. Serum adenosine deaminase (ADA) has been suggested as a potential biomarker for various metabolic conditions, including inflammation and kidney injury, but its association with diabetic kidney health remains understudied. Objective: To assess the association of serum adenosine deaminase (ADA) levels with acute kidney injury (AKI) in patients with type 2 diabetes. Methods: This observational comparative study was conducted at DHQ Teaching Hospital KDA, Kohat, from February 7, 2023, to August 7, 2023, following ethical approval. A total of 120 participants were enrolled, including 60 patients with type 2 diabetes and 60 non-diabetic controls. Laboratory investigations for both groups included serum ADA (U/L), HbA1c (%), and estimated glomerular filtration rate (eGFR) (mL/min/1.73 m²). Statistical comparisons between groups were made using appropriate tests, and correlations between serum ADA and other parameters were assessed. Results: The mean age of diabetic patients was 55.40 ± 8.29 years, and that of controls was 54.58 ± 21.64 years. The mean serum ADA level in diabetic patients was significantly higher at 43 ± 4.29 U/L compared to 16.32 ± 1.20 U/L in controls (p = 0.0001). Diabetic patients had a mean HbA1c of 8.30 ± 0.59%, significantly higher than that of controls (5.28 ± 0.59%) (p = 0.0001). The mean eGFR in diabetic patients was 82.61 ± 17.22 mL/min/1.73 m², lower than in controls (105.97 ± 12.07 mL/min/1.73 m²) (p = 0.0001). In diabetic patients, serum ADA levels were positively correlated with HbA1c (indicating poorer glycemic control) and negatively correlated with eGFR (suggesting declining kidney function). Conclusion: Elevated serum adenosine deaminase levels in type 2 diabetic patients are significantly associated with poor glycemic control and decreased kidney function. These findings indicate that serum ADA could serve as a potential biomarker for monitoring glycemic status and kidney health in diabetic patients at risk for acute kidney injury.

Authors: Al-Yassiri Ammar Talib , Al-Hilli Ali Bakir , Al-Sabti Mohammed Hatem , Al-Sabti Ali Mohammed
Published: October 2024

Background: War-induced. Compound fractures cause considerable damage to the limbs, affecting mobility and quality of life; surgeons consider managing compound fractures to be a difficulty. Although multi-stage conversion from external to internal fixation is still common, multiple studies worldwide are promoting single-stage conversion. Objective: To assess the efficacy and safety of a single-stage conversion from external to internal fixation using the functional results of many Iraqi war wounded patients who were initially treated with external fixation. Methods: A retrospective cohort study analyzed the data of 40 war-wounded patients (39 males and 1 female) ranging in age from 18 to 50 years. All patients came with war-related complex fractures, which were stabilized and referred for external fixation. Following a single-stage conversion to internal fixation, the patients were followed up to assess the functional outcomes of this approach using Ketenjian's functional criteria. Results: A study of 40 patients (45 limbs), mostly male (97.8%), demonstrated a statistically significant link between non-union and time to convert from external to internal fixation. However, fracture type, Gustilo categorization, fixation method, and complication rates had no significant impact on Ketenjian's score results. Conclusions: The single-staged external to internal fixation conversion is regarded as a safe and reliable procedure with good overall functional outcomes; it could be performed by experienced surgeons instead of two-staged conversions, taking into account the patient's general health and the state of the local soft tissue.
Vegetative propagation of Aegiceras corniculatum, a tree mangrove: Biochemical and anatomical basis of adventitious rooting
Authors: Basak U. , Mahapatro S. , Das P.
Published: October 2024

Possibility of artificial regeneration through vegetative propagation of Aegiceras corniculatum (Myrsinaceae) was studied. Rooting in air-layer was induced with the aid of root promoting substances like IAA, IBA and NAA. Maximum rooting ability (in terms of percentage of rooting and root number) was recorded in the air-layers treated with IBA 2500 +NAA 5000 ppm with a promising rate of survivability. Untreated air-layers, however, did not produce any root. Anatomical and biochemical changes were investigated during rooting. Exogenously applied auxins hastened rooting by stimulating cambial activity resulting in the formation of root primordia from phloem parenchyma and eventual root emergence after 27 days of treatment. The rooting response in the air-layers might be determined by higher level of carbohydrate and lower level of nitrogen (a high C/N ratio) especially at the root initiation stage which was confirmed by the activity of amylase, a hydrolysing enzyme. The metabolism of auxins during rooting might be due to enhanced activity of peroxidases and polyphenol oxidase, which had a protective and preparatory role on auxins. Present study revealed a high possibility of scaling up propagation of Aegiceras corniculatum, an economically important tree mangrove through air-layering for use in afforestation programmes.

Interrelationships among crown diameter, diameter at breast height and stump diameter of silver fir trees
Authors: Shrivastava M. , Singh R.
Published: October 2024

The paper describes the statistical procedure in a case study of Silver fir (Abies pindrow Spach.) forests of Western Himalayas in India to assess the breast height diameter and crown diameter of trees from stump diameter with the help of regression and correlation analysis. A series of regression equations have been developed using the stump diameter (DSH) as independent variable while crown diameter (CD) and breast height diameter (DBH) as dependent variables. With the incorporation of DSH in the equation, the DBH and CD of the felled and removed trees can be accurately predicted. The method is simple and easily applicable. The results will provide clues to detect the undersize recordings and excessive felling of trees. For each diameter class the crown area, number of trees per ha and the number of trees per ha after thinning can be calculated and a table constructed. This will provide an aid in thinning of even-aged crop and thinning can be done for any stage of the crop quantitatively, using this table.

At a time when global religious diversity and immigration issues are becoming more and more prominent, countries are facing new challenges in the relationship between religion and law. By means of comparative analysis, this paper first summarizes the legal frameworks of the two countries, and then explores the roles of their respective legal systems in protecting religious freedom and preventing discrimination in the light of typical cases. It is found that the UK prefers the influence of the European Court of Human Rights, while the US has constructed a unique legal system at the federal and state levels. Meanwhile, in the handling of cases, the United States is simply more inclined to protect the individual right to freedom of religion and impose severe restrictions on the government, while the United Kingdom is more willing to balance individual rights to freedom of religion with the common good of society. Finally, based on the results of the study, recommendations are made to improve the legislation and implementation of this aspect in each country.
The Boundaries of Transgender Rights: A Case Study Based on the Historical Legislation of the United States
Authors: Wang Xinyu
Published: October 2024

The U.S. started to legally recognize transgender as transexuals in the 1970s, but with the late 1980s gender queer theory, the U.S. legal system recognizes all transgenders by how they identify themselves. The 2010s see rapid growth in transgender movements and related surgical industries. This paper studies the historical development of transgenders rights in the U.S. and analyzes its legitimacy based on past legislation and ideologies of America. It uses historical analysis and case studies on past lawsuits of the development of transgender. It analyzes how the three aspects of social, economic, and political factors intertwine to form the current legislation regarding transgenders. It divides the post-1980s transgenders into two groups to analyze, each based on a historical analysis of legislative values in the U.S. The current development of transgender rights and the over-protection of which has violated the U.S.s founding ideologies of liberty. To ensure the basic right to privacy in sex-divided facilities, legal systems should give clear criteria for determining transgender. To protect transgenders, especially adolescents and young adults, legislation needs to outlaw the school-to-clinic pipeline.
The Impact of the WTO Agricultural Agreement on Developing Countries
Authors: Zhang Ziqi
Published: October 2024

Abstract: Agricultural insurance, as an agricultural risk management tool to disperse agricultural risks, compensate farmers' losses and safeguard agricultural production, has become an indispensable part of the agricultural security system in various countries. However, due to the high cost of agricultural insurance, many countries provide financial subsidies for agricultural insurance. This paper introduces the help of agricultural insurance subsidies to countries in World Trade Organization (WTO), summarizes the main features and inadequacies of relevant WTO rules, and analyzes the existing problems of agricultural insurance subsidies from four aspects based on the practice of American agricultural insurance subsidies. The main conclusions of this paper include: first, the rules of agricultural insurance subsidy are limited and the classification is not clear, which seriously harms the agricultural development of developing countries; second, income insurance and natural disaster insurance in premium subsidies are regarded as "green box" tools, which need to meet certain conditions, otherwise there is still the possibility of being regarded as "amber box" tools; third, the current WTO rules on agricultural insurance subsidies are more conducive to the development of developed countries, but the agricultural insurance subsidies in developing countries lag behind and are difficult to implement, and the rules on agricultural insurance subsidies urgently need to be improved. Fourth, the double standards of developed countries and developing countries have caused differences in the classification of agricultural insurance subsidies. Finally, the thesis puts forward some suggestions on the compliance development of China's agricultural insurance subsidies under the framework of WTO rules.

Authors: Huang Jiachen
Published: October 2024

Abstract: China is rapidly becoming one of the most significant luxury goods markets in the world. As people's incomes continue to rise, an increasing number of individuals are inclined to purchase brand products to show their social status or satisfy psychological desires after fulfilling their daily living needs. This paper delves into the physiological and external factors that create a distinction between the emotions of "liking" and "wanting" in the context of luxury consumption. The primary objective of this research is to help consumers better understand their consumption motives, thereby helping them avoid impulsive or blind purchases. By utilizing literature analysis and review methodologies, the study categorizes and synthesizes the existing knowledge, beginning with the definitions of the two emotions to uncover the deeper influencing factors. It is found that from a neuroscience perspective, the brain regions responsible for generating "liking" and "wanting" are distinctly different; In the realm of luxury consumption, social factors, traditional Chinese cultural values, and individual differences play crucial roles in distinguishing between "liking" and "wanting".
Consumer Confusion: The Sole Focus of Trademark Law
Authors: Lou Qiqi
Published: October 2024

Abstract: In recent years, the expansion of the global marketplace, driven by the digital revolution, has led to a growing complexity in trademark disputes. The balance between protecting intellectual property and preventing consumer confusion has become increasingly delicate. Traditionally, trademark law was designed primarily to prevent consumer confusion and ensure fair competition. However, with the introduction of the dilution concept, this focus has shifted, resulting in expanded trademark rights that can inhibit innovation and free competition. This paper revisits the original intent of trademark law, advocating for a refocus on consumer confusion as the core principle. Through an examination of legislative intent, theoretical underpinnings, and case law, this paper demonstrates the need to reorient trademark protections to ensure they serve the broader goal of market fairness and economic development. This research highlights that excessive protection of trademark rights can lead to monopolistic practices, which ultimately harm both consumers and market competition. It contributes to the ongoing discussion about how to balance trademark rights with consumer protection, aiming to guide future legal reforms that foster both innovation and competition.
Neuroplasticity and Cocaine Exposure During Adolescence
Authors: Zeng Xinyi
Published: October 2024

The adolescent brain is particularly vulnerable to the effects of cocaine exposure due to ongoing neurodevelopment especially in areas that are crucial for cognitive and emotional regulation. This review explores the multifaceted impact of cocaine on neuroplasticity during adolescence, thereby highlighting both the immediate and long-term consequences of drug exposure. Key findings from recent studies indicate that cocaine use during adolescence leads to significant alterations in synaptic plasticity, dendritic spine morphology, and neurotransmitter systems, which may persist into adulthood and contribute to addictive behaviors. Additionally, the interaction between genetic predispositions, environmental stressors, and drug exposure is emphasized. The review also analyzed the risks of early-life stress and social isolation on cocaine-induced neuroplasticity, which can render anxiety-related behaviors and lead to neurological changes. Future studies should incorporate longitudinal design to understand the long-term trajectory of neuroplasticity induced by cocaine. This paper can provide some suggestions to the development of prevention and intervention programs for adolescents at risk.
Research on the Impact of Gender Role Perceptions on Women's Educational Opportunities in Urban and Rural China
Authors: Li Miya
Published: October 2024

This study explores the impact of gender role perceptions on womens educational opportunities in urban and rural China, focusing on how socio-cultural, familial, societal, and personal factors contribute to educational disparities. Through a comprehensive review of existing research, the study tests three hypotheses: (H1) perceptions of gender roles in urban areas correlate with higher educational attainment among women compared to rural areas; (H2) exposure to progressive media positively influences educational ambitions across both urban and rural contexts; and (H3) increased access to technology narrows the gender gap in education between urban and rural women. The findings underscore the persistence of traditional gender norms in rural areas, which hinder womens educational progress, while urban areas benefit from more progressive views that support higher educational attainment. The study also highlights the significant role of media and technology in challenging traditional gender norms and promoting educational equality. By addressing these factors, policymakers and educators can develop targeted strategies to reduce educational disparities and foster gender equality in both urban and rural China.
