the debate over the contribution of the internet to democracy is farfrom settled. some point to the empowering effects of online discussionand fund raising on recent electoral campaigns in the us to argue thatthe internet will restore the public sphere. others claim that the internetis just a virtual mall, a final extension of global capitalism into everycorner of our lives. this paper argues f...

abstract due to low spatial resolution or simplifying of some micrometeorological phenomena, atmospheric general circulation models are not able to give a good estimation for weather conditions over study area. so their outputs should downscale into weather stations scales. in this research data of hadcm3 downscaled by using lars-wg5 with three scenarios, confirmed by ipcc including a1b, a2 and...

background: excellence and quality models are comprehensive methods for improving the quality of healthcare. the aim of this study was to design excellence and quality model for training centers of primary health care using delphi method. methods: in this study, delphi method was used. first, comprehensive information were collected using literature review. in extracted references, 39 models we...

in the present paper, a 3d numerical model has been applied to predict the flow hydrodynamics around power intakes within the dez dam reservoir. the dez dam is a 203 m high, double arch concrete dam which is constructed by italians in 1962. since then, sedimentation in reservoirhas continued and since the dam does not have bottom outlet, the reservoir bed level is raising by a rate of about 2.5...

this paper considers the search problem, introduced by srivastava cite{sr}. this is a model discrimination problem. in the context of search linear models, discrimination ability of search designs has been studied by several researchers. some criteria have been developed to measure this capability, however, they are restricted in a sense of being able to work for searching only one possible non...

to describe the rheological behavior of polymer blends using emulsionbased (palierne theory) as well as micromechanical models (coranapproach), two immiscible polymeric blend systems of poly(trimethylene terephthalate) (ptt)/polyamide-12 (pa12) and ptt/polyethylene (pe) having different levels of molecular interactions were investigated as model systems. the role of interfacial interactions, vi...
