      Total body irradiation (TBI) is a kind of external beam radiotherapy which is used in conjunction with chemotherapy with the purpose of immunosuppression before bone marrow transplantation. As recommended by AAPM dose distribution uniformity in TBI is very important and dose variation must be within ±10% of prescription dose. Patients treatment geometry for TBI techniques fall into two co...

The application of N fertilizers with surface irrigation stream (surface N fertigation( is a key approach for fertilizer management. The main objective of this study was to investigate furrow fertigation management effects on distribution uniformity and runoff losses of nitrate in field scale. A field corn experiment was carried out with a complete randomized block design having 12 experiments....
