elevated atmospheric carbon dioxide and other green house gases have increased the earth temperature in recent century, which it affects all biochemistry cycles in soils. to examine the effect of atmospheric co2 concentration and temperature on n forms in soil solution in a calcareous soil, an experiment was conducted in a completely randomized design with factorial arrangement in the laborator...
copper trimesate (cu-btc) mof has been pointed out as a promising adsorbent for separating carbon dioxide from methane. however, mof’s need to be shaped prior to their use in packed bed adsorbers in order to reduce pressure drop; on the other hand, the production of mechanically resistant shaped bodies reduces their adsorption performance. in this work, cu-btc tablets provided by basf are evalu...
ترجمه با گسترش زبان آغاز شده و اهمیت آن روز به روز افزایش می یابد، و برای اولین بار به عنوان شاخه ای از دانش و روشی برای انتقال علوم، فرهنگ و تجربه در در دوره قاجار در ایران آغاز شد. در حقیقت متون تاریخی از اولین متونی هستند که در ایران ترجمه شدند چرا که به سیاستمداران آن دوره کمک می کردند تا به علل موفقیت جهان غرب و پیشرفت هایشان در طول تاریخ پی ببرند، بنابراین به تدریج ترجمه این گونه متون رون...
Issues related to environment are one of the most important issues that confront communities in recent decades. Resource scarcity and the necessity of development for Iran and other similar countries requires us to deal with carbon dioxide emissions as a manifestation of environmental crisis. In this study, we assess the relationship between carbon dioxide emissions as a dependent variable wi...
chapter i provides an overview of structural linguistics and touches upon the saussurean dichotomies with the final goal of exploring their relevance to the stylistic studies of literature. to provide evidence for the singificance of the study, chapter ii deals with the controversial issue of linguistics and literature, and presents opposing views which, at the same time, have been central to t...
if the precise implementation of the principle of proportion and:balance between the violation and the penalty as well as the other dimensions could be considered as a stick yard for the imptementation of justice any lack of preciseness in carrying out such principle would not indeed be much too far from injustice . naturally ,if it would be imagined that the objective of balance between...
Effect of water gas shift reaction (CO+H2O=CO2+H2) on wustite reduction has been investigated by a transient, non-isothermal mathematical model based on grain model. In this model, wustite porous pellet is reduced using Syngas, namely a mixture of hydrogen, carbon monoxide, carbon dioxide and water vapor. For this purpose, governing equations containing continuity equation of species and energy...
abstract: proverbs are of the language materials which of the food of any language depends on the quality and quantity of these same materials. in the present research, the researcher tried to present the ramsarian proverbs according to four variables of color, fruit, plantsand animals that selected from the book of the members of each of these four variables, put them into the spss system fo...
the aim of this study has been to find answers for the following questions: 1. what is the effect of immediate correction on students pronunciation errors? 2. what would be the effect of teaching the more rgular patterns of english pronunciation? 3. is there any significant difference between the two methods of dealing with pronuciation errore, i. e., correction and the teaching of the regular ...
The effects of atmospheric carbon dioxide on corn, soybeans, loblolly pine, and sweetgum were studied in the field during a growing season. The plants were exposed to a range of concentrations of carbon dioxide day and night in open-topped, flow-through chambers. At a mean daytime carbon dioxide concentration of 910 parts per million, increases in total biomass ranged from 157 to 186 percent of...
