The high cost of performing chemical assays has a significant impact on the overall cost of uranium exploration. Between 2015 and 2016,the Resource Upgrade Project Zone 2 was undertaken at the Husab Project,which identified the reliability and feasibility of γ probing through comparison of chemical uranium assays with uranium equivalent grades. This project analyzed the sources of errors and proposed a method to correct them. Uranium equivalent data from gamma probing can be used to replace the chemical assays to reduce the cost and time,therefore increasing the efficiency for uranium exploration at the Husab Uranium Project.展开更多

Thus, aim of this study was to assess patient safety practice and the perceived prevalence of medical errors at Jimma University Specialized Hospital, Southwest Ethiopia. Methods: A facility based cross-sectional study was conducted during June, July and August 2010 in Jimma University Specialized Hospital. Patient safety grade and the perceived prevalence of medical errors were computed descriptively. Then, the effect of various independent variables on patient safety grade was assessed using multiple linear regressions analysis. Result: The overall patient safety grade as rated by the participants was excellent (7.2%), very good (20.7%), acceptable (36.0%), poor (30.0%) and failing (6.4%). Complications related to anesthesia occurred sometimes, rarely and never according to 30.8%, 43% and 15.8% of the respondents, respectively. Death in low mortality patients was reported to occur most of the time by 10.4% of the respondents. In addition, failure to rescue, infection due to medical care, postoperative hemorrhage, postoperative sepsis, birth injury to the neonate, obstetric trauma to the mother were reported to happened. Supervisor expectation and actions promoting patient safety (p < 0.001), and communication openness and feedback about errors (p = 0.002) had positive correlation with patient safety grade. Conclusion: this study indicated that poor patient safety practice and potentially preventable medical errors in the hospital.展开更多
