Flexural behavior of cold-formed steel concrete composite beams

Flexural behavior of thin walled steel-concrete composite sections as cross sections for beams is investigated by conducting an experimental study supported by applicable analytical predictions. The experimental study consists of testing up to failure, simply supported beams of effective span 1440 mm under two point loading. The test specimens consisted of composite box and channel (with lip placed on tension side and compression side) sections, the behavior of which was compared with companion empty sections. To understand the role of shear connectors in developing the composite action, some of the composite sections were provided with novel simple bar type and conventional bolt type shear connectors in the shear zone of beams. Two RCC beams having equivalent ultimate moment carrying capacities as that of composite channel and box sections were also considered in the study. The study showed that the strength to weight ratio of composite beams is much higher than RCC beams and ductility index is also more than RCC and empty beams. The analytical predictions were found to compare fairly well with the experimental results, thereby validating the applicability of rigid plastic theory to cold-formed steel concrete composite beams

A study on knowledge, attitude and practice of using cosmetics among the university students

Back ground: Cosmetics are an integral part of daily routine and strongly reinforced by the culture and society. But, there is a poor understanding of the safety issues and risks associated with the use of these products which are undergoing incredible advancements. The ingredients used for preparation of cosmetics are also rapidly changing. This scenario mandates public education campaigns to teach consumers about these risks and the importance of concomitant use of cosmetics. Methods: The study is a cross-sectional observational study involving 300 university students based on their knowledge, attitude and practice. This research was conducted from December 2021 to February 2022. The variables studied were mostly on behaviour of students and their opinions. The statistical test used was the chi-square test. Results: The results showed that most common age range was 21-25 that is 57% and most of the undergraduate students 51.3% and postgraduate students 48.7% in total had a positive knowledge, attitude and practice. There were significant relationship between knowledge, attitude and practice. Conclusions: We observed that there is no significant difference between knowledge and attitude scorings. And there is significant difference between knowledge and practice scorings.&nbsp
