investigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
a study on the design of bio-ethanol process from date wastes of sistan and baluchistan province
اتانول کاربردهای متنوعی در صنایع لاستیک سازی، رنگسازی، حلالها ومکمل سوخت خودرو دارد. اتانول برخلاف نفت از جمله مواد تجدیدپذیر محسوب می شود که مشکلات زیست محیطی و آلودگی نیز ایجاد نمی کند. استفاده از اتانول به عنوان مکمل سوختخودروها از جمله مهمترین مصارف صنعتی این ماده بشمار می رود. با توجه به این موضوع تحقیق و توسعه در زمینه تولید اتانول با درجه خلوص بالا در سطح جهان، و نه تنها در کشور های پیشر...
DETERMINATION OF THE OPTIMUM CONDITIONS FOR RECOVERY OF GOLD FROM ZARSHURAN REFRACTORY GOLD SULFIDE ORE
The orthogonal array design has been used to determine the optimum conditions for gold recovery from Zarshuran refractory gold sulfide ore (Iran) by direct cyanidation and roasting-cyanidation. The Taguchi method was used as the experimental design to determine the optimum conditions of dissolution behavior of gold with cyanidation and roasting-cyanidation from Zarshuran refractory gold ore . T...
متن کاملAssessment of Anaerobic Baffled Reactor Upgrade by Integrated Electrocoagulation Process for Municipal Wastewater Treatment
Background & objectives: Anaerobic baffled reactor (ABR) is one of the low cost wastewater treatment systems compared to the aerobic method. Hoverer it should be studied and developed to overcome its limitations such as insufficient nutrient removal. The aim of this study was to evaluate the efficiency of the 5 sectional ABR pilot and improve it with integrated electric coagulation process for ...
متن کاملKINETIC STUDIES FOR GOLD LEACHING OF A REFRACTORY SULFIDE CONCENTRATE BY CHLORIDE–HYPOCHLORITE SOLUTION
In this paper, gold leaching of a refractory sulfide concentrate by chloride–hypochlorite solution was investigated and effects of stirring speed, temperature and particle size on the leaching rate were reported. Experimental data for leaching rate of gold were analyzed with the shrinking–core model. Results were consistent with chemical reaction control mechanism in the first 1 h of leachin...
