Comparison of Gamma Index Passing Rate in Several Treatment Planning System Algorithms

Dosimetric Evaluation of Dose calculation algorithms of Monaco Treatment Planning System in the heterogeneities area

Introduction: In radiation therapy, the accuracy of dose calculations by a treatment planning system (TPS) is important to achieve tumor control and to spare normal tissue. Treatment planning system calculations in the heterogeneous situation may present significant inaccuracies. In this study, three different dose calculation algorithms, pencil beam (PB), collapsed cone (CC), ...

Simulation of gamma irradiation system for a ballast water treatment

  ABSTRACT Background: Invasion  by  different  kinds  of  ballast  water  microorganisms  is  one  of  the  most important  marine  environment  problems  around  the  world therefore  preventing the  invasion  of  these  unwanted  and  harmful  stowaways  is  one  of  the  main strategies  of  responsible  agencies.  Some  of  these  methods  such  as  ocean excha...

comparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.

heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
