Background: Prevalence of tobacco use is variable among psychiatric illness across the world. Tobacco consumption may predispose or worsen the psychiatric illnesses. Aims: To study the prevalence of tobacco use among psychiatric in-patients and to study the association between various sociodemographic variables and clinical variables with tobacco use. Materials and Methods: A cross sectional study was conducted among psychiatric in-patients (n=200) at a tertiary care psychiatric hospital. Consecutive sampling technique was applied. A semi-structured proforma was applied to capture the socio-demographic and clinical details of the participants. The Fagerstrom Test for Nicotine Dependence (FTND) was applied to assess for the tobacco dependence. Results: Prevalence of current tobacco use among the study population was 39.5%. Among the psychiatric illness, prevalence of tobacco use is significantly higher in substance use disorders when compared with mood disorders (χ2=7.757, p=0.005) and schizophrenia and other psychotic disorders (χ2=24.093, p<0.01). Tobacco use is significantly associated with male gender (χ2=20.820, p<0.01), employment (χ2=7.860, p= 0.005) and marital status (χ2=7.930, p= 0.019) among psychiatric patients. Conclusion: Prevalence of tobacco use was found to be high among psychiatric population. There is a need to focus on the adequate management of tobacco use along with primary psychiatric conditions.

Introduction: Coronavirus Disease 2019 (COVID-19) Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is an infectious and devastating disease that has created heightened levels of anxiety and fear among the general population. COVID19 has also brought many changes in everyone’s lives including closing of schools, colleges/universities and social isolation in an unexplained manner. In these unprecedented times lot of sway has been developed among teaching faculty, students and student’s parents in the medical profession including dental schools. However, the impact on students is likely to be noteworthy. Aim: To assess the awareness, attitude, anxiety and perceived mental healthcare during the COVID-19 pandemic among dental faculty, students and their parents in South India. Materials and Methods: A cross-sectional, observational questionnaire based study was carried out among 1000 dental faculty, students and student’s parents in South India during August 2020 to December 2020. A questionnaire with 20 items regarding awareness, attitude, anxiety and perceived mental healthcare was designed on Google forms and sent through E-mails and WhatsApp. Snowball sampling technique was used and 1000 self-selected dental faculty, students & students’ parents in South India were included in the study. Data was subjected to statistical analysis using Statistical package of social science (SPSS) software v.20.0 International Business Machines Corporation-United States of America (IBM-USA). Chi-square test was used to analyse the data. The p-value <0.05 was considered statistically significant. Results: The findings showed all the respondents were aware with positive attitude and awareness on this pandemic in regard to its spread and precautions to be taken. However, parents (59.2%) were more preoccupied with eliminate thoughts and more were anxious when compared to faculty (32.1%) and students (32.4%), whereas faculty were more concerned about family’s health and safety (49%) and financial status (54.6%) (p<0.001). All the respondents felt that getting engaged and sharing their worries would help them and mental health help requirement is greater in students (86.5%), student’s parents (81.4%) followed by faculty (71.5%) (p<0.001). Conclusion: During this pandemic even though respondents were aware of the possible squeal of infection and preventive measures. The findings suggest a need to address the mental health worries of the people during these pandemics.

Rotor blades of helicopters must be stiff and strong enough to maintain structural loads within working limits. The rotating cycles change the aerodynamic and structural stresses created by the blade revolution. In this project, you will discover the structural stresses of the blades as well as the vibration frequencies studied using the Ansys programme, taking into consideration environmental consequences. This material was tested utilising Kevlar 49, carbon-epoxy, and advanced carbon fibre composite materials and found to be a lightweight, high-strength, and long-lasting material. Solidworks software was used to create the design.
