Bioluminescence tomography using eigenvectors expansion and iterative solution for the optimized permissible source region
A reconstruction algorithm for bioluminescence tomography (BLT) has been developed. The algorithm numerically calculates the Green's function at different wavelengths using the diffusion equation and finite element method. The optical properties used in calculating the Green's function are reconstructed using diffuse optical tomography (DOT) and assuming anatomical information is provided by x-...
متن کاملPiezosurgical Mandibular Ridge Expansion for Immediate Implant Placement
Edentulism of a long standing nature leading to severe alveolar ridge atrophy with a resultant thin ridge often pose a great challenge to the clinicians for rendering implant supported prosthesis in that region. The ideal treatment in such a scenario will be the ridge expansion procedure for achieving an increase in the available bone volume at the implantation site. The space thus created betw...
متن کاملMaximum permissible loading and Static voltage stability limit of a power system using V-I polynomial
P-V or Q-V curve are commonly used to determine the maximum permissible load or static voltage stability limit of a power system. Voltage versus current relation approximation is presented as a tool to assessThe voltage stability limit.determination of the maximum permissible loading of a power system is essential for operating the system with an adequate security margin. A very simple and stra...
متن کاملCold Temperatures . Will They Limit Range Expansion ?
The hemlock woolly adelgid (HWA), Adelges tsugae Annand, primarily infests trees along the eastern seaboard in USDA plant hardiness zones where the minimum low temperature does not exceed –28.8°C. Laboratory studies were done to determine the low lethal temperature of HWA collected in January, February, and March from locations within different USDA plant hardiness zones. The Mt. Tom, Massachus...
متن کاملBenzene Exposure Near the U.S. Permissible Limit Is Associated with Sperm Aneuploidy
BACKGROUND Benzene is a common industrial chemical known to induce leukemia and other blood disorders, as well as aneuploidy, in both human blood cells and sperm at exposures > 10 ppm. Recent reports have identified health effects at exposure levels < 1 ppm, the permissible exposure limit (PEL; 8 hr) set by the U.S. Occupational Safety and Health Administration. OBJECTIVE We investigated whet...
