The purpose of this study was to evaluate the effects of livergol drug on growth indices and prevention of fatty liver disease in different levels of fat in common carp diets. In 2017, 9 diets of different nutrients were prepared with 3 levels of 0, 0.5 and 1% livergol and three levels of 5, 10 and 20% fat. The fish were fed for 180 days. After the end of breeding period, fish growth indices (e...
Jerusalem artichoke is a low-requirement crop, which does not interfere with food chain, and is a promising carbon source for industrial fermentation. Microbial conversion of such a renewable raw material to useful products, such as lactic acid, is an important objective in industrial biotechnology. In this study, high-optical-purity l-lactate was efficiently produced from the hydrolysates of J...
introduction: attention to food safety and health at all stages from production to consumption is inevitable. inappropriate sanitary status of the food production, distribution and supply centers caused food-borne diseases. the aim of this study was to evaluate the environmental health indicators of halva and tahini production centers in the city of ardakan in 2013. materials & methods: this is...
food safety is considered as an important world concern. the detection of pathogen and toxic materials in food has an important role in public health care. in recent years, the applications of microbial biosensor have been developed as a new approach for toxicity control. luminescent microbial biosensor is an appropriate biological tool for protection of natural environment. this type of biosen...
polybutadiene nanoparticles were synthesized via batch emulsion polymerization of butadiene in the presence of potassium persulfate, disproportionate rosinate potassium cation and t-dodecyl mercaptane as initiator, emulsifier and chain transfer agent, respectively. polymerization reaction was performed at different temperatures (60, 70 and 80 °c). conversion was measured at the various time int...
in this study, the effect of garlic extract on the growth performances ( body weight increase (bwi), specific growth rate (sgr), condition factor (cf), final length (fl) and weight (fw)), feed indices (feed conversion rate (fcr), protein efficiency ratio (per), protein production ratio (ppr)) and body composition (protein, fat, moisture and ash) of mugil cephalus larvae were studied in four tre...
chapter i provides an overview of structural linguistics and touches upon the saussurean dichotomies with the final goal of exploring their relevance to the stylistic studies of literature. to provide evidence for the singificance of the study, chapter ii deals with the controversial issue of linguistics and literature, and presents opposing views which, at the same time, have been central to t...
today, information technology and computers are indispensable tools of any profession and translation technologies have become an indispensable part of translator’s workstation. with the increasing demands for high productivity and speed as well as consistency and with the rise of new demands for translation and localization, it is necessary for translators to be familiar with market demands an...
Protein food modulates the activity of proteases of the midgut gland of Penaeus vannamei. Shrimp fed with food containing 15, 30 and 50% protein exhibited differences in trypsin and chymotrypsin activity and trypsin mRNA levels. Shrimp fed with 30% protein showed higher trypsin and chymotrypsin activities than those fed 15 or 50% protein. An additional paralogue trypsin was observed with electr...
the quest for power has formed much of the world history especially in 20th and 21st centuries. oil (energy) particularly after industrial revolution has been a tool for conquest and power and has been transformed to a geopolitical issue. from a geopolitical point of view this has been the case for the last two centuries in central asia and caucasus. central asia and caucasus has always been...
