PURPOSE This study reports the feasibility of the symmetric fields for the usage of asymmetric fields, and checks the accuracy of treatment planning system (TPS). MATERIALS AND METHODS A GE Saturne-42 linear accelerator, which produces dual photon energies of 6 and 15 MV, and an ISIS-3D TPS were used in this study. Percent depth doses (PDDs), dose(More)
A numerical study has been carried out on partially heated triangular enclosures with eave. The eave and inclined wall has a cold temperature. The laminar, two-dimensional, steady governing equations of natural convection are solved in the streamfunction-vorticity form using a finite difference technique. Streamline, isotherm and Nusselt number are(More)
The cereal cyst nematode, Heterodera filipjevi (Madzhidov) Stelter, was detected in Turkey in 1996 and since then it has been increasingly reported to cause losses in wheat yields. Cereal cyst nematode populations have a wide genetic diversity which makes it difficult to be managed. The objectives of this research were to investigate the genetic variation(More)
