in one pole of the continuum of language learning, theoreticians and practitioners traditionally consider english as english as a second language or english as a foreign language. however, in the other pole of this continuum where english is thought of as the most effective tool for international communication, it is referred to as a lingua franca. those who favor an approach to english growing...
Background and Aim: Availability and low cost of date stones make them useful as raw material in the preparation of activated carbon. Cyanide, because of its toxicity for humans and aquatic organisms, is one of the most important health problems. The aim of the present study was to evaluate cyanide removal from aqueous solutions and determine influencing parameters in its adsorption into activa...
purpose a metabolic abnormality such as obesity is a major obstacle in the maintenance of the human health system and causes various chronic diseases including type 2 diabetes, hypertension, cardiovascular diseases, as well as various cancers. this study was designed to summarize the recent scientific knowledge regarding the anti-obesity role of curcumin (diferuloylmethane), which is isolated f...
Background: One of the possible carcinogenic substances found in foods is Acrylamide (AA). This study aims to combine and innovate sea grapes (Caulerpa racemosa) extract with activated carbon into paper towels that can absorb AA levels in fried foods. Methods: The paper towel was created with composition of activated carbon: sea grapes extract: paper pulp using following formula: F0=0:0:100; F...
as the canon is shaped by white male standards rewriting the canonical works of literature is one of the ways through which postcolonial writers subvert the authority of the masters. writing in the language of the masters the colonized writers use the very suppressive tool in the hands of the masters i.e. their language to question the validity of their norms. regarded by most critics to be the...

Parachlorophenol has an extended usage in refineries, petrochemical industries, insecticide, and herbicide manufacturing industries. Tire a solid waste, which is disposed in large amounts each year, a large number of them in landfills can cause irreparable environmental impacts. Consequently lots of efforts were done to produce activated carbon from used tires. Activated carbon was made in labo...
Adsorption of 1-Butanol, Phenol, and P-nitrophenol on activated carbon havebeen studied. The results were used to testifying the validity of different modelsbased on thermodynamic principles: Freundlich, Langmuir and Henry isotherms.The maximum capacity of adsorbent for three compounds was determined, Theconstants of equilibrium were determined by Freundlich isotherm and virialisotherm expressi...
