Rough data envelopment analysis (RDEA) evaluates the performance of the decision making units (DMUs) under rough uncertainty assumption. In this paper, new discussion regarding RDEA is extended. The RSBM model is proposed by integrating SBM model and rough set theory. The process of reaching solution is presented and this model is applied to efficiency evaluation of the DMUs with uncertain ...

Background and objectives: According to recent studies, homotaurine may be an Alzheimer's active ingredient. The goal of this project was to extract and detect homotaurine in algae collected from Persian Gulf shores. Methods: Extraction was done with etanol 80% for 30 min in ambient temperature. The HPLC elution solvent required a mixture of two solvents. Solve...

introduction radioactive materials naturally exist in the world. indeed, approximately 82% of human-absorbed radiation doses, which are out of human control, arise from natural sources of radiation including cosmic, terrestrial, and exposure through inhalation or ingestion. thus, the aim of the present study was to estimate health risk, as well as the effective and organ doses from naturally oc...

introduction: one of the most common syndromes in parkinson's disease (pd) is rigidity. currently, an index is used to evaluate the level of pd by the clinical measurement of rigidity in the upper extremity. the index uses a subjective method called unified parkinson's disease rating system (updrs). the subjective nature of this method makes the influence of physician in the measureme...

Introdouction: Canal length measurement is essential for proper endodontic treatment. Any error or miscalculation in working length determination, particularly in curved canals, can result in complications during or after root canal therapy. Digital radiography has enabled accurate measurement of curved canal length. In this study, we evaluated the accuracy of calibration of a complementary m...
