Introduction: The aim of this study was to evaluation radiobiological modeling parameters on tumor control probability (TCP) for prostate cancer in three different models. These parameters included α⁄β ratios and cell surviving fraction at 2 Gy (SF2). Materials and Methods: The Poisson, equivalent uniform dose (EUD) and linear quadratic (LQ) models was used as...

two new potential magnetic resonance imaging contrast agents, gd-hematoporphyrin (gd-h) and gd-tetra-carboranylmethoxyphenyl-porphyrin (gd tcp), were synthesized and applied to nude mice with human melanoma (mm 138) xenografts. these agents showed a high relaxivity because of their greater potential to coordinate water molecules. the reduction of t1 relaxation times of 16 and 21% was observed i...

Mobile Ad hoc Networks (MANETs) are becoming popular technologies because they offer flexibility in setting up anytime and anywhere, provide communication support on the go. This requires use of Transmission Control Protocol (TCP) which is not originally designed for MANET environments; therefore, it raises serious performance issues. To overcome deficiency original TCP, several modifications h...

Over two decades, a problem of location dependent has been focused for improving the communication Bandwidth-Power Efficiency of homogeneous networks. The efficiencies of communication links are weakened by the Hidden Terminal Problem.  Thus we propose a Fine – Tune Strategy for analyzing the On-Off communication region. We were observed that the proposed technique had been able to track and mo...

Since tubes are widely used for different industrial applications, processing of tubes by the Severe Plastic Deformation (SPD) method has been the target of different attempts. Among these attempts, development of SPD processes for tubes based on Equal Channel Angular Pressing (ECAP) has been more successful. As an illustration, Tube Channel Pressing (TCP) has been presented as an attractive SP...

Since tubes have numerous industrial applications, different attempts are focused on the severe plastic deformation processes of tubes. As an illustration, tube channel pressing (TCP) is an attractive process for this purpose since it can be used for processing of different sizes of tubes. However, more attempts are needed to improve the outcomes of TCP. For example, imposing of a greater strai...
