background: human hair can be used as an inexpensive and accessible adsorbent to remove a variety of pollutants from air. although several studies have been done on removal of formaldehyde from wastewater by human hair, to date no study has investigated using hair to remove formaldehyde from air. therefore, the aim of this study was to remove formaldehyde from synthetic contaminated air by a re...

creation of urban identity is the important subject in architecture and urban design. so, this article foci’s on the creation of identity in urban context with participation approach in architecture and urban design. corporate architecture is an architectonic discipline which focuses on designing and constructing buildings, spaces or environments with the aim of meeting the needs of a business ...

nitrate pollutants increase the growth of algal bloom, resulting in fresh water eutrophication. the high nitrogen level in wastewater has become a growing concern, which has risen the necessity to develop efficient nitrogen removal techniques. biological denitrification, which is the reduction of oxidized nitrogen compounds like nitrate or nitrite to gaseous nitrogen compounds, is the most impo...

the work of architecture is believed to depend on the governing thought in the process of architectural designing. this thought can be analyzed, developed, experienced, and interpreted. creativity is the only domineering force in the idea of designing which is in quest for freeing architecture from the routine methods, and also finding the novel systems to answer the questions in architecture. ...

the present study investigated the use of interactive metadiscourse resources (imrs) in terms of appropriacy during a process- based writing course by applying qualitative and exploratory methods. moreover, learners' perception was investigated to find out how confident they felt as they were writing and rewriting the drafts. 30 intermediate efl learners were chosen to participate in this study...

objective(s): in recent years, the biosynthesis of gold nanoparticles has been the focus of interest because of their emerging application in a number of areas such as biomedicine. in the present study we report the extracellular biosynthesis of gold nanoparticles (aunps) by using a positive bacterium named streptomyces fulvissimus isolate u from rice fields of guilan province, iran.materials a...

in this work, the synthesis of porous structure of cadmium oxide with multilayered sheet-like morphology in nano-meter size using adipic acid as soft template by solvothermal/thermal decomposition process is reported. chemical analyses exhibited that the formation of porous sheet-like structure is originated from bidentate coordination mode of adipate units to cd-center. it was found that the c...

according to ipcc report 2013, the role of man in environmental catastrophe is incontrovertible because of high greenhouse emission in now and recent century. buildings nearly discharge one third of these pollutants and the task of architects to prevent this hazardous procedure is critical. in the other hand, one main basis of sustainability is education due to preserve environment and then, tr...
