Abstract

Background
As the COVID-19 virus spreads, it has new opportunities to change, and new variants of the virus are expected to occur. Health care workers (HCWs) are potential victims of the disease and spread it. They are more vulnerable to infection due to their occupational and nonoccupational exposure. The aim of this study was to identify the frequency and determinants of the acceptance of health care providers to receive the booster dose of COVID-19 vaccine.

Methods
An online questionnaire was used to collect data by the Egyptian HCWs. The questionnaire had four sections: the first section included the participants’ sociodemographic data, the second section included data on the participants’ previous COVID-19 infection status, the third section was on COVID-19 vaccine-related information, and the fourth section evaluated the intention to take the booster dose, causes of acceptance or refusal, and any suggestions to combat COVID-19.

Results
A total of 413 HCWs completed the questionnaire. Females represented 79.9%, and 37.3% had direct contact with COVID-19 patients, and 61.7% had previous infection. The vast majority (94.2%) received COVID-19 vaccine, 52.1% agreed to receive the booster dose, while 47.9% refused. The most common reason to receive booster dose was for increasing protection against new variants (48.4%) and lowering rate of severe illness and hospitalization (41.4%). Male gender and previous COVID-19 vaccination were the main determining factors of acceptance to receive booster doses.

Conclusion
Acceptance of COVID-19 booster vaccination was relatively inadequate among the HCWs. Male gender and previous COVID-19 vaccination were determinants of acceptance.

INTRODUCTION:
Hyperbaric oxygen therapy (HBOT) indeed holds significant therapeutic potential across various medical conditions, primarily by increasing the concentration of oxygen delivered to tissues under pressure. Saturating tissues with oxygen allows for the effective alleviation of underlying hypoxia, facilitating healing, tissue repair and mechanisms of action leads to reducing concentration of pro-inflammatory acute phase proteins, interleukins, and cytokines. Conversely, HBOT while also boosting levels of growth factors and other cytokines that promote angiogenesis. REVIEW METHODS: The article was complied by analyzing data from PubMed and Google Scholar regarding effects of hyperbaric therapy.
THE STATE OF KNOWLEDGE:
Studies indicate that HBOT provides numerous opportunities in the treatment of extensive diseases acress various systems. Neurodegenerative disorders involve progressive nerve cell damage leading to motor or cognitive decline, exacerbated by oxidative stress and inflammation. HBOT has shown promise in delaying disease onset by improving mitochondrial dysfunction in motor neuron disease. In case of intestinal obstruction HBOT reduces intestinal gas volume, diameter of obstructed loops, and improves intestinal contractility. Significant benefits have been observed in conditions such as Crohn's disease and ulcerative colitis. Hyperbaric therapy presents potential benefits for the infertility, improving the environment for blastocyst implantation and pregnancy.
CONCLUSION: There is no doubt that HBOT has a beneficial impact on treatment of many systems such as the nervous, cardiovascular, digestive, and skeletal. This innovative approach of hyperbaric therapy extends to selected disorders such as neurodegenerative diseases, Crohn's disease, ulcerative colitis, and infertility.

The impact of serial mergers and acquisitions on enterprises’ total factor productivity: The mediating role of digital transformation
Authors: Tan Liyan , Zhang Xiaoxu , Song Yu , Zou Fei , Liao Qiaoran 
Published: November 2024

Research background
M&A (Mergers and acquisitions) is a strategic measure for enterprises to expand their scale, enhance their competitiveness and improve productivity in the market competition. As a new factor of production, data is changing the factor input model and value creation path of enterprises.

Research objectives
From the perspective of serial M&A, this study explores the impact of serial M&A on enterprises’ TFP (total factor productivity) and the mechanism of digital transformation between them.

Research methods
Take the serial M&A transactions of China’s A-share listed companies from 2010 to 2019 as samples, using the theory of organizational learning to analyze the relationship among serial M&A, enterprises’ TFP and the degree of digital transformation. Three-step regression is used to construct a model that serial M&A indirectly affects enterprises’ TFP through intermediary variable digital transformation.

Research finding
There is a significant inverse U-shaped relationship between serial M&A and enterprises’ TFP, and digital transformation plays a mediating role in this relationship. The impact of serial M&A on enterprises’ TFP shows an upward trend at first and then a downward trend and this relationship is indirectly realized through digital transformation. The results are still valid after considering the change-explained variables, lag test, Sobel-Goodman test, and Bootstrap test. Heterogeneity analysis shows that for enterprises with non-state-owned property rights, smaller enterprise scale, and higher business environment index, serial M&A has a more obvious effect on TFP indirectly through the degree of digital transformation.

Research value
It further enriches the existing literature on the decision-making of M&A from the perspective of serial M&A and profoundly reveals the mechanism of the degree of digital transformation in the relationship between serial M&A and enterprises’ TFP. The research provides theoretical support and empirical evidence for enterprises to achieve high-quality development.

Published: November 2024

Abstract
The peel and pulp of soursop are ideal for creating a new tea product, offering a unique flavor compared to traditional leaf tea. This study develops mathematical models to describe the drying process, decomposition of bioactive components, and antioxidant activity of soursop slices. The slices were dried at four temperatures (20–50°C) using industrial-scale heat pump drying. Changes in moisture ratio (MR) were calculated and compared with 30 previous models. Additionally, two and four mathematical models were used to analyze data on total flavonoid content (TFC) and antioxidant activity. The model fits were evaluated based on statistical parameters (R
2, root mean square error, χ
2). The results indicated that the drying process at 20°C involved two mechanisms following the Aghbashlo model (R
2 > 0.993). At higher temperatures, the moisture removal process followed a single mechanism. Zero order, first order, and polynomial quadratic models were suitable for describing TFC decomposition and antioxidant activity, depending on the temperature. The activation energy of MR (29.89 kJ/mol) was lower than that of 2,2′–azino-bis–3–ethylbenzothiazoline–6–sulfonic acid (37.02 kJ/mol) and 2,2–diphenyl–1-1-picrylhydrazyl (32.12 kJ/mol), indicating drying efficiency and retention of bioactive components. The study’s findings are expected to enhance quality, improve economic efficiency, and expand the market for soursop tea.

Published: November 2024

Abstract
The orthogonal decomposition (OD) of special linear Lie algebras over the complex numbers was first explored in the early 1980s and has gained renewed interest in the past decade due to its applications in quantum information theory. In this study, we investigate the OD of special linear Lie algebras over commutative rings with identity. Additionally, we present examples of specific rings that facilitate the existence of such ODs for these Lie algebras.
A Biopolymer Coating Strategy for the Slow Release of Urea from Urea Fertiliser
Authors: Demirci Tuba , Tecim Gelen Tuğba , Bölgen Nimet 
Published: November 2024

Due to the rapid dissolution of urea fertilisers in water, leaching and evaporation from the soil cause approximately 70 % of the urea to be lost to the atmosphere and groundwater without being used by plants. It is known that a significant portion of urea fertiliser is released into the atmosphere as ammonia gas, and into groundwater as nitrate and nitrite, resulting in nitrogen losses. To mitigate these losses, various studies have been conducted on coating urea fertiliser with different materials. Biopolymers, in addition to providing controlled release, also act as soil conditioners by increasing the water-holding capacity of the soil and providing necessary moisture to plants during dry periods. In this study, three different types of biopolymers – chitosan, pectin, and xanthan gum – at two different concentrations (1 % and 3 %), were used to coat urea fertiliser aiming for controlled release. Biopolymer solutions and their cross-linkers were prepared, and the urea fertiliser was coated using a laboratory-scale coating drum. The chemical structure of the coated urea fertiliser was determined using Fourier-Transform Infrared Spectroscopy, and its morphology was examined with a Scanning Electron Microscope. The water-holding capacity in the soil and the ammonia released into the atmosphere were also analysed. The results indicated that the most effective biopolymer coating type for the slow-release mechanism of urea was pectin at a 1 % coating ratio on the fertiliser granules. The concentration of ammonia released from the soil and the water-holding capacity of the soil treated with biopolymer-coated urea fertiliser were tested through various experiments, and the results were analysed statistically. According to the statistical analysis, the 1 % pectin-coated urea fertiliser yielded the best results in both experiments, with an ammonia release value of 246.66 ppm and an evaporation rate of 67.84 % at the end of 30 days.

Published: November 2024

Background: Comprehensive studies on the determinants of modern contraceptive use in humanitarian settings are relatively uncommon in Bangladesh. The aim of this study was to examine the prevalence and determinants of modern contraceptive use among Rohingya women living in the refugee camp of Cox's Bazar, Bangladesh.
Methods: A cross-sectional survey was conducted among 160 Rohingya refugee women aged 15-49 living in unregistered camps (Camps 7 and 14) in Ukhiya Upazila, Cox's Bazar. In the study, participants were selected using a convenience sampling method, and the sample size was calculated using the single population proportion formula. However, only 160 participants were recruited due to travel restrictions and safety measures implemented throughout Bangladesh during the COVID-19 pandemic. The data were gathered via a structured questionnaire. Results were summarized using both descriptive and inferential statistics and SPSS v.23 software was used for data analysis at 5% level of significance.
Results: The prevalence of contraceptive use was found to be 41.9%. The most commonly used contraceptives were Injection Depot-Provera
(65.7%) and Oral Contraceptive Pill (OCP) (28.4%) followed by implant (4.5%) and intrauterine device (IUD) (1.5%). Multivariate logistic regression revealed lower odds of modern contraceptive use among women who had more than a 1.5 year interval between the last two pregnancies (OR = 0.19; 95% CI = 0.07– 0.51) and higher odds were found who expressed a lack of desire for future pregnancies (OR = 13.69; 95% CI = 3.43–54.68). Community Health Workers (CHWs) (80.4%) were the main sources of information on modern contraceptives, whereas hospitals (83.6%) were the most accessible places to obtain contraceptives.
Conclusion: Community health workers play a vital role in disseminating information, emphasizing the need for their training and involvement in relevant programs. These findings are crucial for shaping future research, policies, and reproductive health services in humanitarian settings.

Published: November 2024

Introduction: Andropause is a condition that affects men as they age, similar to menopause in women. Unfortunately, there is limited research on this topic in Iran, and many men are unfamiliar with this concept. To address this knowledge gap, a study was conducted to investigate the attitudes and awareness of andropause among men over the age of 40 in Ardakan City.
Methods: This study was conducted on 281 men aged over 40 years from Ardakan city in 2019. The sampling method used was cluster sampling and data were collected through a researcher-developed questionnaire. The collected data was analyzed, using SPSS software version 18 and the statistical methods of variance, Pearson correlation, and regression were used.
Results: Men have a low level of awareness about andropause, and their attitude towards it is negative. The study found that the mean score of participants’ awareness about andropause was significantly impacted by age groups (P <0.05), education level (P <0.05) and occupation (P <0.05). In terms of attitude towards andropause, the mean score was significantly impacted by age groups (P <0.05) and occupation (P <0.05), but not by education level (P >0.05). The Pearson correlation coefficient shows that there is a statistically significant positive relationship between the mean score of awareness and the score of attitude.
Conclusion: The low awareness and negative attitudes towards andropause among men in Ardakan City emphasize the need for more education and awareness on this topic. Providing men with accurate information about the symptoms, causes, and management of andropause is crucial to help them make informed decisions regarding their health. By addressing the knowledge gap and promoting positive attitudes towards andropause, healthcare providers can enhance the overall well-being of men in this age group.

There is a context of socio-political inequalities and unmet needs for sex work, which constitute an extreme injustice. The objectiveof this article is to analyze the social determinants of health that generate inequity in the sex worker population of a Colombian city. Quantitative research with an associative approach was used, and the population consisted of 131 cisgender and transgender sexworkers. Snowball sampling was carried out, and the information was entered into the Gender Observatory system and was processed and analyzed with SPSS. Among the results, the average age was 34.24 ± 9.610 years, range 18 to 61 years. A total of 59.6% reported being single, 7.6% had no education, and 29.8% had only primary school education. Fifteen percent were not enrolled in health insurance, and 96.9% reported incomes of less than one minimum monthly salary. This reflects the vulnerability, inequity and challenges in various dimensions of human development. The conditions of education, health and employment were the social determinants that generate the greatest inequity, therefore, the formulation of public policies for the benefit of sex workers will address these challenges to ensure adequate access to education, health services and labor rights, with the empowerment of this group that has been violated to improve their quality of life.
