Parameter shielding refers to the situation that one test parameter disables others in test execution. The quality of test case generation techniques is limited by the wide existence of parameter shielding. It is challenging to automatically find out conditions that cause the parameter shielding. This paper presents a novel approach for exploring the shielding conditions of test parameters. Our...

background: while young men are at higher risk of developing testicular cancer (tc), testicular-self examination (tse) is an easy, cost effectiveness method to early detection of this disease. the aim of the study was to investigate medical sciences student`s awareness, attitude and self-efficacy about tc and tse. methods: this cross-sectional study was carried out among full time young student...

Exposure to ionizing radiation in the space environment is one of the hazards faced by crews in space missions. As space radiations traverse spacecraft, habitat shielding, or tissues, their energies and compositions are altered by interactions with the shielding. Modifications to the radiation fields arise from atomic interactions of charged particles with orbital electrons and nuclear interact...

background the gonadectomy in patients with androgen insensitivity syndrome (ais) has been conventionally performed using laparotomic techniques. but currently several reports have suggested laparoscopic gonadectomy in these patients because of shorter hospital stay and minimal postoperative pain and hemorrhage. objective to report the laparoscopic gonadectomy in 11 patients suffering from andr...

PURPOSE The integration of a low field biplanar magnetic resonance (MR) imager and linear accelerator (linac) causes magnetic interference at the linac due to the MR fringe fields. In order to eliminate this interference, passive and active magnetic shielding designs are investigated. METHODS The optimized design of passive magnetic shielding was performed using the finite element method. The...

F or a shielded cable, an approximate relationship valid from few kHz up to the first cable resonance can be derived from its Transfer Impedance (Zt ) allowing to predict the cable shielding factor. This Cable Shielding factor, as a figure of merit, is often preferred by engineers dealing with product specifications and early design. Being not necessarily EMC specialists, they can relate it dir...

An extensive study of 13C and “B shielding values of icosahedral heteroatom boranes is described. Shielding effects on polyhedral atoms due to variations (a) in directly bonded exopolyhedral groups, (b) in ortho cage groups, (c) in meta cage groups, and (d) in para cage groups are outlined. A linear relationship between ‘“C and llB shielding values of isoelectronic and isostructural icosahedral...

Introduction: In radiation therapy centers across Iran, protection of normal tissues is usually accomplished by either Cerrobend or lead block shielding. In this study, the influence of these two shielding methods on central axis dose distribution of photon beam a Cobalt unit was investigated in clinical conditions. Materials and Methods: All measurements were performed for 60Co γ-ray beams an...
