Opis:
The method of obtaining hydroxyapatite by thermal treatment of deproteinised and defatted bone pulp called bone sludge was presented. The products of the calcining process were characterized with X-ray diffraction (XRD) and Fourier transformed infrared spectroscopy (FT-IR). The calcium content was determined with titration, whereas the contents of total phosphorus - with a spectrophotomertric method. X-ray investigations confirmed that hydroxyapatite was the main component of the calcining products in the calcining process. The FT-IR spectra confirmed that all organic substances were removed during the calcining process. On the basis of the research into physiological liquids the propensity to resorption of hydroxyapatite bioceramic was evaluated.

Opis:
The proper management of biomedical waste has become a worldwide humanitarian topic today. Although hazards of poor management of biomedical waste have aroused the concern worldwide over, especially in the light of its far –reaching effects on human, health and the environment. Now it is well established fact that there are many adverse and harmful effects to the environment including human being which are caused by the “HOSPITAL WASTE” generated during the patient care. Hospital waste is a potential health hazards to the care workers, public, flora, fauna of the area. The problems of the waste disposal in the hospitals and other health care institutions have become issues of increasing concerns. This research article is to survey the practice of biomedical waste such as collection, storage, transportation, and disposal along with the amount of biomedical waste generated in two Hospitals of Gulbarga. The proper management methods have been employed in Government hospital. In Basaveshwara hospital there is no proper segregation of waste at the source of generation and all the wards don’t contain all the liners. In both the hospitals waste collected and disposed daily. It is highly desirable for a Hospital Administrator to know the weak points in the chain of waste management so that these could be addressed appropriately. Keeping this in view, the present study was conducted to assess generation and management of biomedical waste in Government General Hospital and Basaveshwara Hospital.

Opis:
The generation of sharp waste from the activities of health care facilities is unavoidable. Waste needles are considered one of the most problematic issues in health facilities. This study involved an experimental investigation of reusing waste needles (WNs) in concrete mixes to partially replace the natural fine aggregate at 0%, 2%, 4%, 6%, 8% and 10% by weight. The mechanical and physical properties of the WNs-concrete mixes have been studied and compared to conventional concrete mix. The workability test, fresh and hard densities, compressive and flexural strengths, water absorption, and leaching test were carried. The curing ages considered for the concrete mixes were 7, 14, and 28 days. The results revealed that the WNs-concrete mixes exhibited improved flexural strength and workability, decreased water absorption capacity and improved durability. The compressive strength values of WNs-concrete mixes gradually decreased, but they were higher than the targeted mean strength of M17 grade concrete.
