The Crab Pulsar is a relatively young neutron star. The pulsar is the central star in the Crab Nebula, a remnant of the supernova SN 1054, which was observed on Earth in the year 1054. The Crab Pulsar has been extensively observed in the gamma-ray energy band by the Large Area Telescope (LAT), the main instrument onboard the Fermi Gamma-ray Space Telescope, during its first months of data takin...

OBJECTIVE To describe the outcomes of dorsal augmentation rhinoplasty with expanded polytetrafluoroethylene (ePTFE) implants in Southeast Asian patients from the Philippines. METHODS Retrospective review of 1054 patients. RESULTS Of the 1054 patients, 90.61% were women and 9.39% were men. One thousand eight patients (95.64%) underwent primary rhinoplasty; 46 (4.36%), secondary or revision r...

A survey to identify the aetiology of hearing impairment among Saudi children was carried out. Children were divided into 2 groups according to presence or absence of laboratory evidence of toxoplasmosis "at risk' and "not at risk.' Serological tests for toxoplasmosis were done to 1054 children. We found positive IgM antibody against Toxoplasma gondii in the blood of 70 of the 1054 children (6....

The graph-theoretical S-tree technique developed for the study of the nonlinear Nbody systems, is used for the study for the first time of the substructure of a high redshift cluster of galaxies, namely of MS 1054-03, z ≃ 0.8. Nearby galaxy clusters studied via the same S-tree code reveal several clearly distinguished subgroups with significant bulk velocities. Therefore the study of distant cl...
