low grade grape juice concentrate was used as carbon source for xanthan production. significant factors affecting xanthan concentration, productivity and viscosity were investigated using plackett-burman design. based on the obtained results, carbon and nitrogen concentrations, inoculum size and agitation rate, were assumed as significant factors. broth culture viscosity and xanthan concentrati...

Today, great observatories around the world, devote a substantial amount of observing time to sky surveys. The resulted images are inputs of source finder modules. These modules search for the target objects and provide us with source catalogues. We sought to quantify the ability of detection tools in recovering faint galaxies regularly encountered in deep surveys. Our approach was based on com...

Vaginal varix during pregnancy is a rare condition. Only a few cases have been reported in the literature. Most vaginal varices are asymptomatic, but some are associated with a sense of local mass, or severe discomfort and spontaneous vaginal bleeding. A 32-year-old woman was admitted for acute spontaneous vaginal bleeding at 37+6 weeks’ gestation. Upon pelvic inspection, we observed dilated va...

In this study, we propose a model which may assist in diagnosis of (AD) using T1 weighted MRI brain images. The proposed model involves construction of statistical features from multiple trans-axial slices from hippocampus and amygdala regions, which play a significant role in AD diagnosis. Features from multiple slices are then averaged, which resulted into a smaller set of relevant features. ...
