the current regulated particle metric in vehicle emissions is the total mass, while during last decade interest in number size distribution has increased. various international studies on epidemiology and toxicology have reported the adverse effect of the particle matter on public health. the unece group of experts on pollution and energy (grpe) under particle measurement program (pmp) are unde...

the clean development mechanism (cdm) under the kyoto protocol is the only mechanism with dual objectives in which non-annex b countries of the protocol, particular developing countries, have the ability to participate in it. certified emission reduction (cer) units resulting from the activities of the cdm projects are the tradable units that usually traded by the participants in these projects...

the optimization model for evaluating regional and global effects of greenhouse gases reductionpolicies named merge is an actively usable tool for studying some aspects of the problem of climate change.it is first of all destined for the quantitative estimation of emission trajectories and results of applyingabatement measures. in the paper, the emphasis is on the adaptation of the integrated a...

a preliminary design of a polygeneration system (combined cooling-heating-power plant with a desalination unit), is proposed for a tourist resort located on the spanish coast. the well-known trigenerationconcept is enhanced to the included production of desalted water, considering for the purpose three different options: reverse osmosis (rodp), multi-effect (medp) and a combination of rodp and ...

in this research, the energy flow and production energy indices of canola cultivation in trakya province of turkey, golestan and mazandaran provinces of iran were compared. diesel fuel and chemical fertilizer inputs were the highest consumer of energy in the production of canola in these three regions. the results indicated that despite the higher energy use of machinery in trakya province of t...

new two nano- sized schiff base complexes [m(l)], where l= 2, 2'-((1e, 1e')-(1, 2 phenylen bis (azanylylidene)) bis (methanylylidene)) bis (4-bromo phenolato) and m=cu or zn, (a, b complexes) were synthesized by ultrasonic irradiation. these complexes were characterized by elemental analysis, molar conductivity, ft-ir, fluorescence emission, 1h nmr, field emission scanning electron sp...
