barrier properties are one of the most important factors in the edible film. in this study, edible mungbean films were prepared containing (0%, 15%, 30%, 45%) concentrations of rosemary aqueous extract. then the effect of rosemary was investigated on colorimetric and barrier properties (water vapor permeability, oxygen permeability). rosemary extract increased the absorption of color in the vis...
in this study the factors controlling the software colorimetry (photoshop), including illumination (direct and indirect), image background (white and black), camera settings (zoom, light, resolution and environmental conditions) and the conversion equations of r, g, b images to l *, a *, b *, compared with the results of the device were investigated and optimized. the results showed that the fa...
in this study, quality of white button mushrooms (agaricus bisporus) treated by water and citric acid was evaluated during storage at 2 temperatures (room temperature and 4°c). the effect of modified atmosphere packaging (map, by 4±1% co2, 6±1% o2 and the remaining n2) with or without water absorbent (silicagel) was also evaluated. samples were assessed for their organoleptic properties (textur...
Purpose: This study was conducted in order to determine distributions and changes of glycoconjugates terminal sugars during skin morphogenesis. Materials and Methods: using lectin histochemistry technique, 10% formalin fixed, paraffin embedded rat embryonic sections for days 12, 14, 16 of gestation (N=30) were incubated with different HRP-lectins from Lotus tetragonolobus (LTA), Maclura pomifer...
Background and purpose: Pphenol is one of major available compound in industrial wastewater. Phenol is classified as priority and dangerous pollutant in International Agency for Research on Cancer (IARC) and in list of EPA. Thus, the purpose of this study is survey on effect of sorbitol on phenol removal rate by lemna minor. Materials and methods: Tthis is an empirical- lab study. In this stu...

Background & Aims : Hair follicle morphogenesis is controlled by complex reprocical ectodermal–mesenchymal interactions regulated by molecular mechanisms. In addition, glycoconjugates are known to be important for molecular interactions during developmental processes. The aim of this research was to study glcoconjugate terminal sugars distributions and changes during rat hair follicle morph...
Introduction : Introduction: Gonadogenesis is a complex developmental process which is regulated by molecular interactions such as cell surface and extracellular matrix (ECM) Glycoconjugates terminal sugars. The aim of this study was to determine Glycoconjugates terminal sugars expressions and changes during Gonadogenesis in Rat using Lectin histochemical technique. Methods : To determine o...
Introduction: Iron deficiency anemia is recognized as the most prevalent nutrient deficiency in the world and iron supplements, which are prescribed daily in pregnant women for prevention of this anemia, may have unfavorable effects on copper absorption. The purpose of this study was to determine the effects of iron supplementation on serum copper status of pregnant women. Materials and Methods...
the importance of textile historical works is not hidden from anyone In the field of preservation and restoration of historical and cultural objects. due to the organic structure of cellulose, Historical cotton fabrics are exposed to spontaneous oxidation and the degradation process will not stop even in an isolated environment. Keeping such sensitive works in the unfavorable conditions of the ...
