Original scientific paper This paper presents an analysis of the stress distribution on the outer surface of the riding ring of rotary cement kiln during working cycle using both the theory and finite element simulation. In the theoretical analysis, the total stress is obtained as a combination of bending, thermal and contact stresses. To obtain bending stress the kiln is considered as a simply supported, indeterminate beam subjected to static and symmetrical loads and Castigliano’s theorem is employed. Thermal stresses are obtained assuming both linear and non-linear temperature distribution over the ring thickness. Contact stress between ring and supporting rollers is obtained using Hertz contact theory. Bending, thermal and contact stresses are also obtained numerically in separate simulations, mimicking conditions assumed in the theoretical part. All results are in excellent agreement. In addition, a more realistic ring model subjected to all loads simultaneously is also simulated. These results showed slight disagreement with theory in the contact region, mainly due to sliding contact between the roller and the ring, but overall agreement was good.

Community pharmacists play a significant role in patient/disease management and perception by patients is increasingly important. A self-administered questionnaire was developed consisted of sociodemographic part and 15 questions. Patients have a positive overall perception of community pharmacists that is comparable to most studies in Europe. Community pharmacists’ beyond dispensing drugs play a significant role in patient and disease management. This role of the pharmacist is performed through pharmaceutical care. Patient’s opinion is increasingly considered to be a useful component in the determination of care outcomes and consumer satisfaction is an integral component of the quality of primary health care. For the purpose of this study we developed self-administered questionnaire consisted of sociodemographic part, and 15 questions. Survey has been conducted in 10 pharmacies. Results are presented in tables and figures and descriptive statistics has been used. We found that patients in Bosnia and Herzegovina have a positive overall perception of community pharmacists and of the services offered from community pharmacies that is comparable to most studies in Europe, but there is still room for improvement of relationships and pharmaceutical services.
