roasting has considerable effects on the quality of cream made of nuts. in this study, the roasting conditions of walnut kernels were optimized based on the stability parameters of the produced cream. temperatures of 100-150°c for 10-30 minutes were used to roast walnut kernels. the amount of oil separation, peroxide, acidity and thiobarbituric acid values of the cream, as well as color paramet...
the poor orientation of the restaurants toward the information technology has yet many unsolved issues in regards to the customers. one of these problems which lead the appeal list of later, and have a negative impact on the prestige of the restaurant is the case when the later does not respond on time to the customers’ needs, and which causes their dissatisfaction. this issue is really sensiti...
the present study set out (a) to examine the categories of pedagogical knowledge related to the act of teaching of novice and experienced teachers as gleaned from their verbal report of what they were thinking about while teaching and (b) to compare the categories of pedagogical knowledge of novice and experienced teachers. the aim of comparing these two groups of teachers was to see whether di...
This research investigated the effect of hot water pre-extraction on the bleaching process and properties of wheat straw soda-AQ pulp. Preextraction experiments were carried out on wheat straw to obtain a weight loss of about 15 percent. Based on preliminary experiments, soda-AQ pulping of non-extracted straw chips was performed at 160 oC for 60 min, whereas the pre-extracted chips were pulped ...
In order to produce biodiesel from waste cooking oil and optimize its yield, a two-stage process of esterification/ transesterification has been used in this study. First, we used the acidic catalysts H2SO4 in order to diminish the content of free fatty acid (FFA) in oil that caused reducing the oil acidity from 6.1% to 0.57% through esterification. Then, the biodiesel was produced by transeste...

Abstract: The use of alkali-activated cementitious materials especially over the past decades has significantly been increased. The goal of this research is to investigate the effects of silica modulus and alkali concentration on alkali-activation of blast-furnace slag. In this research, the most important physical characteristics of cementitious systems, i.e. the 28-day compressive strength...
the kinetics of old corrugated container (occ) soda-oxygen delignification was investigated. three delignification temperatures (145,165 and 175ºc) were applied. the pulping duration was adjusted at 150 minutes and the measurements were conducted at 10 minutes intervals. the pulping consistency, oxygen pressure and active alkali were constant at 10%, 6 bar and 18% naoh respectively in all pulpi...
