In the recent decades, water scarcity has become a major challenge for many reasons, especially the inadequate use of water resources. The mineral processing plant is among the most important water-consuming industries. Filtration, as one of the important processes in water recovery, is a process in which the solid-suspended particles are removed from the liquid. In the present work, the effect...

proper sequencing of multiple choice test items is a matter of concern for many constructors. in this study we compared the variances of three different pharmacology test formats for nursing students. the aim of the study is to see if changing the order of questions will have any effect on the grades of the students. one way analysis of variance (anova) was used to compare the mean score of the...

the effect of sonication time (in three levels 0,2,4 min ) and mono- di glyceride (in three levels 0,0.3,0.6 %) on improving the quality of cupcake were studied. color analyze (l*, a*,b*) for dough samples and specific volume, porosity shelf life, color analyze and texture of cake were done. results showed that increasing the levels of each factors (sonication and emulsifier) made a decrease in...

This experiment investigated the effect of feeding different levels of sesame oil cake on the intake and digestibility of DM, CP, crude fiber, and crude fat in Awassi fattening lambs. Sesame oil cake was incorporated into lamhs’ rafions at levels of 10 and 20% to replace similar percentages of barley and soybean. The results showed that the high level of sesame oil cake inclusion decreased DM a...

AIM The current in vitro study was carried out to determine the chemical composition and inclusion level of lime treated olive cake on acid detergent fiber (ADF) replacement basis in adult male goats. MATERIALS AND METHODS Crude olive cake was collected and evaluated for proximate composition and protein fractionation. It was treated with 6% lime and incubated for 1 week under room temperatur...

Filter cake is one of the main waste products of zinc processing industries and it contains a high amount of toxic heavy metals. In this research in order to reduce heavy metals leachability in filter cake, Portland cement, natural pozzolan, diammonium phosphate (DAP), triple superphosphate (TSP), lime, zinc oxide and ground granulated blast furnace slag (GGBFS) have been used. This research’s ...

the aim of this work is to evaluate the influence of fabrication methods on the com-pressive properties of sandwich composites using both experimental work and numerical simulations. two types of sandwich composites with e-glass/kevlar/polyester resin facings and end-grain balsa wood as core have been produced by vacuum infusion processing (vip) and hand-lay up (hl) method. compression tests on...

A series of reverse osmosis (RO) membrane filtration experiments was performed systematically in order to investigate the effects of various hydrodynamic and physicochemical operational parameters on a cake layer formation in colloidal and particulate suspensions. Bench-scale fouling experiments with a thin-film composite RO membrane were performed at various combinations of trans-membrane pres...

Pseudo-nitzschia austrulis Frenguelli is a marine pennatc diatom associated with the production of domoic acida neurocxcitatory amino acid linked to illness and mortality of humans and wildlife, Distinguishing P. austrulis from its co-occurring congeners is labor intensive and time consuming because of a requirement for scanning electron microscopy. Hcrc, we apply large-subunit ribosomal RNA (L...

The purpose of this investigation was to ascertain whether outcome expectancies and criminal thinking would change in offenders participating in a psychoeducational group and whether significant cross-lag (over time) correlations could be identified between outcome expectancies and criminal thinking. A sample of 121 US federal inmates completed the Psychological Inventory of Criminal Thinking S...
