•Extending our previous work on visual keywords, we use the concept of template-based visual keywords using MPEG-7 color descriptors. MPEG-7, also called the Multimedia Content Description Interface, has been a standard for many years. These color descriptors have the ability to characterize perceptual color similarity and need relatively low complexity operations to extract them, besides being...

Abstract: Background: Natural biopolymers or hydrogels that are biodegradable and safe from biological point of view along with their capability to retain active principle within network thus prolonging the release. The present work was undertaken explore potential mucilage mature seeds Chia (Salvia hispanica) sustain release water-soluble drugs. Losartan potassium used as a model prepare gelis...

irrigation with distillery effluent, besides influencing crop yield, may have considerable impact on physical properties of soil because of its high salt and organic carbon contents. this experimental study was conducted to evaluate the effect of distillery effluent on hydraulic conductivity of a sandy loam alluvial soil and compare the effect of inorganic salts of potassium (k) with that of di...

background: it is not clear whether the use of volumetric peristaltic infusion pumps, affect the quality of the erythrocytes during packed cell transfusion or not. in the present study in vitro quality of red blood cells was assessed after using this type of infusion pumps in a prospective study. materials and methods: in this study 60 units of packed red cells were examined before and after pa...

nitration of potassium sulphamate was carried out using a mixture of sulphuric and nitric acid at -30 °c. the reaction time was optimized at the mole ratio of sulphuric to nitric acid of (1:3.5). the difference in product yield by changing the potassium to ammonium sulphamate was studied throughly. it was found that both the yield and purity of the product is better starting with potassium sulp...
