background: rad51 is a protein with critical role in double strand break repair. down-regulation of this protein has a significant effect in radiosensitivity of some cell lines like prostate carcinoma. compared to monolayer cell culture model, the spheroids are more resistant to radiation. the aim of the current study was to determine the rad51 protein level in du145 spheroids, and monolayer ce...

Crop models are ideally suited to quantify existing climatic risks. However, they require historic climate data as input. While daily temperature and rainfall data are often available, the lack of observed solar radiation (Rs) data severely limits sitespecific crop modelling. The objective of this study was to estimate Rs based on air temperature solar radiation models and to quantify the propa...
