The adsorption equilibrium and kinetics of ethanol-water systems on starch-based adsorbents prepared from cassava were undertaken. These include modified cassava starch (MS), cassava starch (CS), cassava pellet (CP), and Cassava shred (AB). The adsorption equilibrium data were best represented by the Langmuir adsorption isotherm. The adsorption kinetics was found to follow second order kinetics...
The effects of heat treatment on oat and barley starch water dispersions were investigated. As compared with barley starch, the granules from oat starch were more degraded, but the fractionation patterns of both starches were not significantly different. Microscopic examination indicated that no evidence of amylopectin fragments was observed in the liquid fraction after starch dispersions were ...
simplification universal as a universal feature of translation means translated texts tend to use simpler language than original texts in the same language and it can be critically investigated through common concepts: type/token ratio, lexical density, and mean sentence length. although steps have been taken to test this hypothesis in various text types in different linguistic communities, in ...
the rationale behind the present study is that particular learning strategies produce more effective results when applied together. the present study tried to investigate the efficiency of the semantic-context strategy alone with a technique called, keyword method. to clarify the point, the current study seeked to find answer to the following question: are the keyword and semantic-context metho...
Background and Objectives: Nowadays, extruded snacks are the most common form of meals; however, their high amount of salt and fat leads to increase disease risk. Their coating would be a proper carrier for probiotics and has an appropriate potential for enhancement of the nutritional properties of puffed snacks. In this research, production of symbiotic snack coating by probiotic bacteria, as ...
The purpose of this study is to develop an analytical method to quantify the nitrogen present at the surface of paper by using X-ray photoelectronic spectroscopy (XPS). A sample of softwood thermomechanical pulp (TMP) was treated with a cationic starch containing primary amines, while another one was treated with a cationic polymer containing quaternary amines. We also grafted monomers containi...
abstract: the potato tuberworm, phthorimaea operculella (zeller), is an important insect pest of potato (solanum tuberosum l.) in the storage and field in most parts of the world especially in tropical and subtropical regions due to its close relationship with the host, high reproductive potential and high economic losses. information on host preference, life table parameters and digestive en...
چکیده کنه تارتن دو لکه ای tetranychus urticae koch یکی از چندخوارترین آفات شناخته شده محصولات کشاورزی دنیا به حساب می آید. در این بررسی جمعیت تخم و مراحل فعال این کنه در شرایط آلودگی طبیعی و مصنوعی در برگ های 8 رقم لوبیا در سال 1392 در گلخانه و مزرعه تحقیقاتی دانشکده کشاورزی دانشگاه ارومیه موردمطالعه قرار گرفت. آزمایش به صورت طرح کاملاً تصادفی برای شرایط مزرعه در10 تکرار و برای شرایط گلخانه ای...
the purpose of this thesis was to investigate how differently metacognitive, cognitive, and social/affective strategies affect l2 learners’ reading comprehension. to this end, the study employed a quasi-experimental design with a placement test as a proficiency test to find the homogeneity of groups. three classes were randomly selected as the experimental groups (n =90), and each class was tau...
Hydroxypropyl starch was synthesized by modified sago starch with hydroxypropylation reaction. Hydroxypropyl starch nanoparticles with mean particle sizes of 110 nm are obtained by controlled precipitation through the drop-wise addition of dissolved hydroxypropyl starch solution into excess absolute ethanol. Piperine was loaded onto hydroxypropyl starch nanoparticles and native starch nanoparti...
