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...
15 صفحه اولTechno-economics of integrating bioethanol production from spent sulfite liquor for reduction of greenhouse gas emissions from sulfite pulping mills
BACKGROUND Flow sheet options for integrating ethanol production from spent sulfite liquor (SSL) into the acid-based sulfite pulping process at the Sappi Saiccor mill (Umkomaas, South Africa) were investigated, including options for generation of thermal and electrical energy from onsite bio-wastes, such as bark. Processes were simulated with Aspen Plus® for mass- and energy-balances, followed ...
متن کاملBioproducts from sulfite pulping : Bioconversion of sugar streams from pulp , sludge , and spent sulfite liquor
The production of singleand mixed-sugar streams and their conversion to bioproducts were studied using sulfite pulping streams as feedstocks. Sulfite pulp, sludge, and spent sulfite liquor (SSL) were utilized because they are concurrently generated alongside of bleached pulp, and because the pulping process renders pretreatment unnecessary. SSL, comprised of mostly monomeric hexose and pentose ...
متن کاملThe soil perfusion technique for the biological degradation of sulfite waste liquor.
Considerable attention has been given to chemical methods of reducing the Biochemical Oxygen Demand (B.O.D.) of semi-chemical neutral sulfite waste (S.N.W.). Very little study has been devoted to a biological method. The exact composition of this paper industry waste will vary with the type of wood chip used and the modification of cook. Table 1 shows a typical composition of the liquor resulti...
متن کاملGrowth-promoting Activity of Spent Sulfite Liquor
The discharge of spent sulfite liquor (SSL), the waste water produced during cellulose manufacture, into water courses often results in massive slime infestations of Sphaerotilus natans. Though a considerable amount of work has been done on the stimulation of Sphaerotilus in mixed populations, the most notable probably being that of Amberg and Cormack (1), very little (6) is known about the nut...
