Catalytical performance of heteroatom doped and undoped carbon-based materials

Developing cost-effective, eco-friendly, efficient, stable, and unique catalytic systems remains a crucial issue in catalysis. Due to their superior physicochemical and electrochemical properties, exceptional structural characteristics, environmental friendliness, economic productivity, minimal energy demand, and abundant supply, a significant amount of research has been devoted to the development of various doped carbon materials as efficient catalysts. In addition, carbon-based materials (CBMs) with specified doping have lately become significant members of the carbon group, showing promise for a broad range of uses (e.g., catalysis, environmental remediation, critical chemical production, and energy conversion and storage). This study will, therefore, pay attention to the function of heteroatom-based doped and undoped CBMs for catalytical applications and discuss the underlying chemistries of catalysis. According to the findings, doping CBMs may greatly improve their catalytic activity, and heteroatom-doped CBMs may be a promising option for further metal doping to attach them to an appropriate place. This paper also covers the potential applications of both doped and undoped CBMs in the future

The Role of Management Information Systems in the History of Mental Health Care for Prisoners in the USA

From the prehistorical to contemporary periods, prisoners’ mental health has been a burgeoning issue in the United States (USA). After a decade of incarceration and a misleading penal system, prisoners' mental health has become a discussed topic for scholars not only in the correctional system but also in other disciplines. Despite having diverse initiatives for the improvement of the penal system, few initiatives have been held to take into consideration of prisoner's mental health. To fill this gap, the main purpose of this paper is to provide a brief overview of the mental health of prisoners by analyzing previous research on the mental health of prisoners along with suggesting some probable ways from management information perspectives that can be helpful to reduce a great number of prisoners and bring some positive changes in the correctional system

SOCIOECONOMIC FACTORS INFLUENCING NUTRITIONAL STATUS OF UNDER-FIVE CHILDREN OF AGRARIAN FAMILIES IN BANGLADESH: A MULTILEVEL ANALYSIS

The nutritional status of under five children is a sensitive sign of a country's health status as well as economic condition. This study investigated differential impact of some demographic, socioeconomic, environmental and health related factors on nutritional status among under five children in Bangladesh whose fathers' occupation was agriculture. The study used Bangladesh Demographic and Health Survey 2007 data. Bivariate analysis, multivariate analysis (Cox's linear logistic regression model) and two-level random intercept binary logistic regression analysis were used to identify the determinants of under-five malnutrition. The analyses revealed that 19.6 percent of the children were severely stunted, 29.4 percent were moderately stunted and 51 percent were not stunted. This study also found that 3.5 percent of the children were severely wasted, 16.5 percent were moderately wasted and 80 percent were not wasted. Furthermore, the analyses revealed that 14.5 percent of the children were severely underweight, 32.5 percent were moderately underweight and 53 percent children were not underweight. The main contributing factors for under five malnutrition were found to be child's age, birth order, mother's education, father's education, family wealth index, sanitation facility, place of delivery, place of residence and division. Community level variations were found significant for wasting only in the analyses

British doctors' work-life balance and home-life satisfaction: a cross-sectional study

PurposeTo assess British doctors’ work–life balance, home-life satisfaction and associated barriers.Study designWe designed an online survey using Google Forms and distributed this via a closed social media group with 7031 members, exclusively run for British doctors. No identifiable data were collected and all respondents provided consent for their responses to be used anonymously. The questions covered demographic data followed by exploration of work–life balance and home-life satisfaction across a broad range of domains, including barriers thereto. Thematic analysis was performed for free-text responses.Results417 doctors completed the survey (response rate: 6%, typical for online surveys). Only 26% reported a satisfactory work–life balance; 70% of all respondents reported their work negatively affected their relationships and 87% reported their work negatively affected their hobbies. A significant proportion of respondents reported delaying major life events due to their working patterns: 52% delaying buying a home, 40% delaying marriage and 64% delaying having children. Female doctors were most likely to enter less-than-full-time working or leave their specialty. Thematic analysis revealed seven key themes from free-text responses: unsocial working, rota issues, training issues, less-than-full-time working, location, leave and childcare.Conclusions This study highlights the barriers to work–life balance and home-life satisfaction among British doctors, including strains on relationships and hobbies, leading to many doctors delaying certain milestones or opting to leave their training position altogether. It is imperative to address these issues to improve the well-being of British doctors and improve retention of the current workforce.</div

Percutaneous nephrolithotomy with or without nephrostomy tube

The study has been designed to compare the outcome of percutaneous nephrolithotomy with (Group A) or without nephrostomy tube (Group B) for the management of renal stone disease. JJ stents were given to all cases of both groups. Comparison of outcome between groups shows that urinary leakage time was significantly longer in Group B than that in Group A (24.0 ± 6.2 vs 7.3 ± 3.9 hours;  p<0.001). Visual analogue pain score was also significantly high in Group B than in Group A (4.7 ± 0.8 vs 2.4 ± 0.5; p<0.035). Patients in Group B stayed in hospital on an average 4 days, while the Group A patients stayed in hospital on an average 2.5 days (p<0.029). The mean hemoglobin decrease in 24 hours in Group B and in Group A (0.5 ± 0.4 and 0.5 ± 0.4 respectively) did not show any significant difference (p<0.895). In conclusion, percutaneous nephrolithotomy without nephrostomy tube can be practiced in the management of selective cases of renal stones diseases

Upgradation of nuclear medical equipment in the developing countries and its impact in Bangladesh

Bangladesh has thirteen Nuclear Medical Centres and one Institute of Nuclear Medicine in the country which are being run and maintained by the physicians scientists and engineers of Bangladesh Atomic Energy Commission. The peaceful application of atomic energy was initiated through all these Centres with the use of clinical isotopes for thyroid and kidney studies. The equipment used for these purposes were the thyroid uptake system, rectilinear scanner and the multiprobe renogram system. The first gamma camera was installed in the country in 1980 at the Institute of Nuclear Medicine, Dhaka. That was the turning point for the country in the field of nuclear medicine. Presently all the nuclear medical establishments are equipped least with a gamma camera, thyroid uptake system and a renogram system. In the last two decades there has been a tremendous development in the design of nuclear medical equipment. Most of the old equipments were slow and manually operated. In the beginning of nineties of the past century there was an uprising in the computer technology and most of the manually operated machines were brought under computerization. It was basically done with a custom built processor to perform only the specific job and spare the users from doing some extra manual work. But the performances of the recent models of the same computerized equipment are by far the best as compared with the past ones. This report describes the role of the IAEA in the upgradation of medical equipment, PC interfacing, upgrading of old gamma cameras and the technological and socio-economic impact in Banglades
