Pretreatment processes are essential for the preparation of biofuels from lignocellulosic feedstocks. Based on alkaline H2O2 pretreatment, photocatalytic pretreatment (U-AHP) was investigated to examine effects reaction time, alkali concentration, and concentration enzymatic digestion corn stover. The optimum process conditions were determined by orthogonal tests: 1% NaOH, 2% H2O2, time 8 h. Un...

Biomass pretreatment is a critical method for improving the anaerobic digestion (AD) performance of lignocellulosic feedstocks. In this study, an effective combined ammonia–autoclave was selected corn straw at 90 °C using four ammonia concentrations (7%, 9%, 11%, and 13%). The results showed that improved substrate’s degradation efficiency system’s buffer capacity, significantly hydrolysis biog...

Background: A common, early postpartum concern of the breastfeeding mother is nipple pain. Because of a lack of effective treatment and opposing results about lanolin, we decided to compare the effect of lanolin ointment and aloe Vera gel on nipple soreness treatment. Methods: This clinical blind trial was performed in Mashhad, Iran, from February 2008 to May 2009. Sampling was nonrandom and pu...

   Two omega-3 fatty acids including docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) are essential for the physiologic function of neuronal cell membrane. Normal function of neuronal cell membrane requires appropriate composition of fatty in its structure. Present study was designed to compare the effect of short-term and long-term pretreatment with omega-3 fatty acids on scopolamine...

The anaerobic digestion of organic waste for biogas production can be affected by some variables such as temperature; concentration of the biogas feed solution, bacteria populations, and pressure. This study investigated the effects of thermal pretreatment at 50, 75, and 100 ºC on the biogas produced by simultaneous anaerobic digestion of cow manure, mushroom waste, and wheat straw at thermophi...

Background:Chitosan and Calcium are one of the natural polymeric materials obtained from the exoskeleton of Xylotrupes gideon through demineralization, deproteinization and deacetylation processes. Nano chitosan and calcium can inhibit the demineralization process, which is caused by the consumption of acetic acid. This study aims to determine the effect of nano chitosan pretreatment and ...
