the skill of reading in english as a foreign language is an important and challenging one which is affected both by linguistic and extra linguistic factors. since vocabularies are part and parcel of every reading comprehension text, knowing enough vocabulary always facilitates this process. however, guessing strategy as one of the most important strategies has consistently ignored by language l...
the rise and stublishment of safavid dynasty was depend on triangle of tasavof, tashayo and royalty, kings legitimized their power upon these. therefore for the understanding the functions of that period we must explore the role of this elements. although application and emphsise upon dignities such as; complete mentor (morshede kamel), deputy of absent imam (nayebe imame ghayeb), and god’s sha...
Zebrafish are rapidly growing in popularity as an in vivo model system for chemical genetics, drug discovery, and toxicology, and more recently also for natural product discovery. Experiments involving the pharmacological evaluation of small molecules or natural product extracts in zebrafish bioassays require the effective delivery of these compounds to embryos and larvae. While most samples to...
The elevated increase of CO2 emissions related to activities the extractive industry is becoming a challenging issue gradually affecting climate change and global warming. In this frame, effective utilisation through techniques Carbon Capture Storage (CCS) as well Utilisation (CCU) can alleviate greenhouse effect. Converting into value-added chemical or liquid fuel (e.g., methanol, hydrocarbons...
Propylene is an important chemical intermediate in the chemical industry, which is conventionally produced either as a co-product to ethylene in steam crackers or byproductin refineries. With the increase in exploration of shale gas, new cracker projects for ethyleneproduction are based primarily on ethane feedstock, which yield almost no propylene [1,2] Onthe other hand, the demand...
Dye-containing wastewater is one of the main environmental challenges that can cause health issues. It is crucial to remove the dyes from wastewater before its discharge into the environment. This study aims to evaluate the efficiency of aptenia cordifolia mucilage in removal of anionic dyes from textile wastewater via coagulation and flocculation process. To this goal, the effect of different ...
Concepts of the modified and the excess Walden products are introduced and discussed when applied together with the ordinary Walden product. The existence of the universal curves of limiting conductances for electrolytes (or for ions) in a given pair of solvents are further examined for a number of mixtures which include ethanol, 2-propanol, 1,1,1,3,3,3hexafluoro-2-propanol, N,N,-dimethylformam...
esl/efl books play a crucial role in shaping language learners worldview of gender roles in society. the present study investigated the status of sexism in two sets of efl textbooks, one developed by non-native iranian authors (ili series) and the other by native authors (top notch series). first, two books from each series was selected randomly. then, a quantitative analysis was carried out wi...
This report presents a cost analysis of Polymer Grade (PG) Propylene production from ethylene and raffinate-2 using a metathesis process. The process examined is similar to CB&I Lummus Technology's Olefins Conversion Technology (OCT). In this process, Polymer Grade Propylene is produced through a metathesis reaction of ethylene with 2-butene, present in raffinate-2 feedstock. This report examin...
