Present work investigates the annealing effects on MgO thin films deposited using e-beam evaporation method. MgO thin films of thickness 5 and 50 nm were evaporated from MgO-pellet in ultra-high vacuum (2×10-8 Torr). As deposited thin films exhibit coordination similar to MgO bulk as envisaged from near edge X-ray absorption fine structure measurements. As deposited films were annealed at 300, 400 and 500oC in open environment. Thickness of films remain unaltered with annealing within experimental error. Raman spectroscopic measurements further confirm the presence of bands associated with Mg-O bonding at such low thicknesses.
Background
Despite acne being a common dermatological problem, there is a paucity of literature addressing the knowledge, attitude and practice about it.
Aims/Objectives
To find out what patients know about acne, its cause and treatment, as well as myths, misconceptions and attitude towards it.
Methods
A cross-sectional, descriptive questionnaire-based study on acne patients at Maharana Bhupal Hospital, RNT Medical College, Udaipur, Rajasthan, India.
Results
Most (84.8%) patients belonged to the age group of 16-25 years. The majority (63.9%) presented 12 months after the onset of acne. More than half had average knowledge, a positive attitude and good practices, related significantly to gender and education.
Limitations
A standardized questionnaire suitable for all dialects and regional languages would have yielded more uniform results.
Conclusion
Study revealed that acne patients still need to acquire accurate, adequate and easily accessible information to seek timely and appropriate treatment, and alleviate their psychological suffering.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
