The relationship between history of schistosomiasis and bladder cancer risk was investigated using data from a case-control study conducted between January 1994 and July 1996 in Alexandria, Egypt. Cases were 190 subjects with incident, histologically confirmed invasive cancer of the bladder, and controls were 187 subjects admitted to hospital for acute,(More)

BACKGROUND Highly pathogenic avian influenza (H5N1) virus continues to cause infections in Egypt. This study describes the practices associated with raising and slaughtering household poultry to identify risk factors for H5N1 infection and reasons for non-compliance with preventive measures. METHODS An investigation was conducted of 56 households with(More)
The purpose of this study is to determine the relative advantages of laparoscopic varicocelectomy compared to the conventional open high ligation of Palomo. We studied 193 patients who presented with varicocele. While 65 patients were treated by open high ligation of the testicular veins, 128 patients had laparoscopic varicocelectomy. In addition to(More)
— A miniature SAW device is designed and fabricated at 1 GHz for wireless communication system. A 5 m thin film of ZnO is successfully deposited using RF sputtering technique on PECVD SiO 2 layer of 1µm on top of Si wafer under various operating conditions. The c-axis oriented ZnO film exhibit a sharp diffraction peak corresponding to the (002) reflection(More)
We present the ambitions of the SWUSV (Space Weather and Ultraviolet Solar Variability) Microsatellite Mission that encompasses three major scientific objectives: (1) Space Weather including the prediction and detection of major eruptions and coronal mass ejections (Lyman-Alpha and Herzberg continuum imaging); (2) solar forcing on the climate through(More)
