Background: One of the means of assessing dose to pa ents from Computed tomography (CT) procedure is through the determina on of the skin entrance dose (ESD) with the apprecia on of the concern that ocular exposure effects from CT scan includes possible induc on of cancer and cataract. Due to the rela vely more recent introduc on of CT scans, li le work has been done in this area in the country...

This new research considers the 3 main motions of moored floater (surge, heave and pitch) in head waves it explores ways to estimate systematic uncertainties on RAOs, 2 other metrics for these signals. Based linear hydrostatics potential flow theory, simple relations can be found that bind characteristics a floater. These are transformed using algebra express how uncertainty bias tested system ...

By performing detailed frequency-dependent radia-tive transfer computations we have obtained UBVI light curves of nonlinear RR Lyrae models, which recently have been calculated by the Vienna nonlinear convective pulsation code. For two sets of stellar parameters (M = 0. the fundamental and the first overtone limit cycle solutions have been calculated for effective temperatures ranging from 6000...

Radiation therapy has been an effective therapeutic modality in the management of both benign and malignant tumors for over a century. The science and technology surrounding the deliv-ery of this targeted treatment has significantly improved our ability to not only control tumors, but to also minimize the untoward complications of irradiating normal tissues. Advances in radia-tion and surgical ...

The activity of stress-activated protein (SAP) kinase is stimulated by diverse agents such as tumor necrosis factor, UV light, and protein synthesis inhibitors. The present study demonstrates that ionizing radia tion (IR) exposure is also associated with the induction of SAP kinase activity. Cells derived from patients with ataxia-telangiectasia (A-T) are characterized by hypersensitivity to IR...

In the IEEE 802.1D standard for the Media Access Control layer (MAC layer) bridges, there is an STP (Spanning Tree Protocol) definition, based on the algorithm that was proposed by Radia Perlman. In this paper, we give a formal proof for correctness of the STP algorithm by showing that finally a single node is selected as the root of the tree and the loops are eliminated correctly. We use forma...
