Excessive use of cytotoxic drugs owing to a dramatic increase in malignancy incidence leads to the production of high amounts of cytotoxic wastes. In Iran, management of hazardous wastes has been neglected in recent decades. The aim of this study was to determine the amount of intravenous cytotoxic drug wastes, their collection and disposal status in(More)
The capacitated p-median problem (CPMP) is one of the well-known facility-location problems. The objective of the problem is to minimize total cost of locating a set of capacitated service points and allocating a set of demand points to the located service points, while the total allocated demand for each service point is not be greater than its capacity(More)
A Hamiltonian path is a path in an undirected graph, which visits each node exactly once and returns to the starting node. Finding such paths in graphs is the Hamiltonian path problem, which is NP-complete. In this paper, for the first time, a comparative study on metaheuristic algorithms for finding the shortest Hamiltonian path for 1071 Iranian cities is(More)
The aim of this cross-sectional study was to investigate the implementation of and compliance with international infection control standards by patients and staff in dialysis centers in Shiraz, Iran. The results indicate negligence in various aspects of infection control. Providing staff education and training programs, establishing effective surveillance(More)
BACKGROUND AND OBJECTIVES Medical waste management is a major concern for healthcare facilities. One important element is the segregation of infectious waste from domestic, non-infectious waste. The aim of this qualitative study was to identify factors that negatively affect proper segregation at Nemazee Hospital, which is affiliated with Shiraz University(More)
