climate change is one of the major global concerns. emission of anthropogenic greenhouse gases is the main cause of climate change. one way of reducing the emissions is the application of carbon capture and storage (ccs) in geological formations. in this study, feasibility of ccs was studied in an iranian gas production area located in the northern persian gulf coast in the south of country. th...

this paper describes a methodology in designing high-performance concrete for simply supported beams, using a hybrid optimization strategy based on a variable neighborhood search threshold acceptance algorithm. three strategies have been applied to discrete optimization of reinforced concrete beams: variable neighborhood descent (vnd), reduced neighborhood search (rns) and basic variable neighb...

background: trace elements play an important role in a number of biological processes. astaxanthin (asx), a carotoid pigment found in certain marine plant and animals, has shown anti cancer and anti free radical properties. this work intended to understand the effect of astaxanthin in breast cancer (invasive ductal carcinoma, idc) by using micro-pixe method. for this aim the concentration of tr...

processing of round potatoes (solanum tuberosum (l.) into chips in tanzania and particularlydar es salaam city is a growing business that attract low wages employees and unemployed occupants. proliferationof chips vendors with low knowledge, poor attitude and practice towards environment have resulted into poormanagement of potato peels waste which are haphazardly disposed of thus causing unhea...

Abstract The spontaneous emission spectrum from a driven three-level atom placed inside a double-band photonic crystal has been investigated. We use the model which assumes the upper levels of the atomic transition are coupled via a classical driving field. The transition from one of the upper levels to lower level couples to the modes of the modified reservoir, and the transition from the oth...

an increase in energy prices will decrease the fossil fuel consumption; on the other hand, the cost-push will encourage technology improvement for firms and households. these changes will affect the emission level.this paper studies the changes of yearly pollutant emissions after an energy price reform in iran. we apply a computable general equilibrium model which consists of 7 energy goods (el...
