Effect Of Calcination Temperature On The Morphology Of Plating Sludge

Abstract— The effect of calcination temperature on the morphology of plating sludge generated from waste water treatment plant was studied. This waste was hazardous waste due to high toxic metal content [1]. It must be recovered, reuse or recycled before the process but its properties should determined in order to decide recovery method [2]. Previous researches were shown that this kind of wast...

the effect of traffic density on the accident externality from driving the case study of tehran

در این پژوهش به بررسی اثر افزایش ترافیک بر روی تعداد تصادفات پرداخته شده است. به این منظور 30 تقاطع در شهر تهران بطور تصادفی انتخاب گردید و تعداد تصادفات ماهیانه در این تقاطعات در طول سالهای 89-90 از سازمان کنترل ترافیک شهر تهران استخراج گردید و با استفاده از مدل داده های تابلویی و نرم افزار eviews مدل خطی و درجه دوم تخمین زده شد و در نهایت این نتیجه حاصل شد که تقاطعات پر ترافیک تر تعداد تصادفا...
