the present study investigated oil/water demulsification and treatment of oily wastewater originated from port waste reception facilities by electro coagulation using aluminum electrodes in a batch reactor. the efficiency of al electrodes in removing ss, cod, and oil & grease from wastewater with different current densities and operational times were investigated. the characteristics of the was...

this paper describes day-one beamlines of the iranian light source facility and design concept of powder diffraction and spectromicroscopy beamlines as the most priorities of each synchrotron that cover the research requirements in the fields of physics, chemistry, nano-science, etc. for powder diffraction beamline energy range is 6-30 kev, resolution: 10-4, flux: 1012(ph/s/0.1%b.w.) and spot s...

background: prompt gamma neutron activation analysis (pgnaa) is known as a non-invasive technique capable of measuring elemental concentration in voluminous samples in a short period of time. also it is a valuable diagnostic tool for total body elemental measurements. 252cf and 241am-be sources which are usually used in this method, generate not only neutrons, but also emit high-energy and unwa...

proposing a robust designed facility location is one of the most effective ways to hedge against unexpected disruptions and failures in a transportation network system. this paper considers the combined facility location/network design problem with regard to transportation link disruptions and develops a mixed integer linear programming formulation to model it. with respect to the probability o...

in this study, results of noise level measurements performed in 4 different mining sites aregiven. noise level measurements performed in opencast mining site of konya ilgin lignite corporation (ilc), in konya eyak mining quarry site and in aydin cine feldspar ore dressing facility have been evaluatedtogether with worker surveys. the noise level measurements performed in manisa soma uyar mining ...

Recently the concept of facility efficiency, which defined by data envelopment analysis (DEA), introduced as a location modeling objective, that provides facilities location’s effect on their performance in serving demands. By combining the DEA models with the location problem, two types of “efficiencies” are optimized: spatial efficiency which measured by finding the least cost location and al...
