BACKGROUND Busulfan(Bus) is a chemotherapy drug that is widely used for cancer treatment. However, administration of busulfan may cause temporary or permanent sterility in male patients. Therefore, reduction of this side is necessary. OBJECTIVE evaluation of the protective effects of L-carnitine and testis homogenized tissue(THT) on sperm parameters and the testis structure after busulfan tre...

noise is one of the major hazardous occupational exposures and one of the occupations at risk is the transportation industry. however, few studies have measured and reported the amount of noise exposure in drivers. in this study, we evaluated noise exposure among the public transportation bus drivers of one major iranian city, kerman, southeast iran. eighty public transportation buses in the st...

Cold atom fountain clocks provide exceptional long term stability as they increase interrogation time at the expense of a larger size. We present compact cold using grating magneto-optical trap to laser cool and launch atoms in simplified optical setup. The is evaluated coherent population trapping demonstrates improved single-shot from launch. Ramsey times up 100 ms were measured with correspo...

Modern drinking water distributions systems (DWDSs) have been designed to transport treated or untreated safely the consumer. DWDSs are complex environments where microorganisms able create their own niches within water, biofilm sediment. This study was conducted on twelve fountains (of three different types, namely types A, B and C) Melbourne (Australia) city area with aim (i) characterize qua...
