The packaging of DNA into chromatin probably places certain restrictions on how specific DNA sequences can be recognized by DNA sequence specific recognition proteins (SRP). Several unique features of this type of interaction are discussed. Specifically, as a consequence of the coiling of the DNA about a histone core, it is proposed that DNA recognition sites will be compound and that each elem...

consumption of food containing cholesterol and saturated fatty acids such as butter can increase serum cholesterol and cause cardiovascular diseases. therefore many efforts have been done for decreasing these constituents in foods. in this study, hazelnut and walnut powders were added to butter samples in amounts of 0 (not enriched sample), 10, 20 and 30% for evaluation of chemical characterist...

A decision-maker is airregularo if she would choose B from {A, B, C} but not from {A, B} (for example, preferring vanilla ice cream in a choice between vanilla and chocolate, but chocolate in a choice among vanilla, chocolate and strawberry). Similarly to previous studies we observed irregular choices by college students faced with hypothetical discount cards for supermarkets. However, older ad...

Cell formation problem in Cellular Manufacturing System (CMS) design has derived the attention of researchers for more than three decades. However, use of sequence data for cell formation has been the least investigated area. Sequence data provides valuable information about the flow patterns of various jobs in a manufacturing system. This paper presents a new mathematical model to solve a cell...

Product packaging is one of the key industrial sectors where automation is of paramount interest. Any product going out to the consumer requires some form of packaging, be it food products, gift packaging or the medical supplies. Hence there is continuous demand of high-speed product packaging. This requirement is dramatically increased with seasonal consumer products and fancy gifts, which inv...

Shelf life extension can reduce food losses throughout the entire chain and packaging be an effective way to attain this goal. Along these lines, active is appealing alternative that uses natural antimicrobial compounds inhibit growth of microorganisms causing spoilage. Specifically, a was developed based on polyethylene film with coating fully compatible (all components declared as additive co...

Objective(s) Since diabetes mellitus is accompanied by cognitive impairment in diabetic patient and animal models and since lipids play important roles in neuronal membrane composition, structure and function; we intended to evaluate the effect of dietary butter oil on passive avoidance memory of streptoztosin (STZ)-induced diabetic rats in this study. Materials and Methods Thirty six adult ...
