gol-e-gohar iron ore mine of sirjan in southern part of iran is a large open pit that operates below the groundwater table and during mining operation, dewatering is required to prevent operation processes from flooding. current operation is going on by digging wells in or out of the pit and pumping to prevent flooding. as a result of the former dewatering operation a vast deep cone of depressi...

Background and Objectives: By increasing consumer demands for food products with no chemical preservatives, use of natural preservatives such as herbs with antioxidant and antimicrobial characteristics as well as effects on physicochemical and sensory characteristics of the products is increasing in food industries. Therefore, the objective of this study was to investigate effects of Echinophor...

boron nitride semiconducting zigzag swcnt, $b_{cb}$$n_{cn}$$c_{1-cb-cn}$, as a potential candidate for making nanoelectronic devices was examined. in contrast to the previous dft calculations, wherein just one boron and nitrogen doping configuration have been considered, here for the average over all possible configurations, density of states (dos) was calculated in terms of boron and nitrogen ...

in this thesis, barium ferrite nano particles were prepared by sol-gel method. their structural and magnetic properties of samples have been investigated using thermo gravimetric analysis (tg-dta), x-ray powder diffractometer (xrd), fourier transform infrared (ftir), scanning electron microscopy (sem), field emission scanning electron microscopy (fesem), ac susceptometer, vibrating sample magne...

The aim of this study was to determine the optimum level of fish protein isolate (FPI) as a fat replacer for the production of a low fat hamburger using Quantitative Descriptive Analysis (QDA) and investigating some of the functional characteristics of the product. For this purpose, FPI was developed from yellowfin tuna fish (Thunnus albacares) canning by-product using pH-shift method. On the o...

abstract nowadaysphotovoltaic solar cells (pvs) areacknowledged the fastest growing energy technology in the word, however, they only account for only fraction of current global renewable energy capacity. it isrecognized that this incomplete market penetration has been largely a result of the technology’sexcessive cost. so researchers are trying to find innovative, economic way with theaim of ...
