Plastic 60Co buildup caps have been widely used to protect ionization chambers when calibrating high-energy x-ray and electron beams in water, and have been used consistently by the Radiological Physics Center. Recent calibration protocols base their calculations on a theory that assumes that no protective cap is used during calibration in phantom. The change in ionization within the chamber du...

Face recognition is important in human identification. The biological recognition technique acts as a good method and broad applications in security areas. This work presents a method to improve the face recognition accuracy using a combination of Principal Component Analysis (PCA), and Wavelet Transform. Wavelet Transform is used to decompose the input image with different levels and rearrange...

Ulva pertusa was incubated in aerated seawater containing 60Co under fluorescent lamp for 7 days. The radio active seaweed was homogenated and...

صخلملا Infertility affects 15% of couples seeking children worldwide and male factor is evident in about 30-50% of the cases. To assess the effect of sperm chromatin integrity on the outcomes of intracytoplasmic injection, sperm DNA compactness was evaluated by acridine orange staining in 40 fertile and 44 infertile men attending one infertility clinic. The results showed no significant differe...

صخلملا The search for novel anticancer drugs continues. This work includes a preliminary study of the effect of two crude extracts of Greek or Mediterranean sage (Salvia triloba L. f.) on three malignant human cell lines and one malignant murine cell line. A boiling water extract and a methanolic extract were prepared from dried leaves of S. triloba. Yields of extraction were 9.8 and 22.4%, res...
