wax precipitate is one of the most serious issues the oil industry is currently facing, since it can cause some troubles such as increasing of the pressure losses in pipe which subsequently increases the required power for pumpage. to remove this problem, prediction of wax disappearance temperature (wdt) seems necessary. in this study, the pressure influence on the wax disappearance temperature...

ABSTRACT The Internet has transformed the nature of business-to-consumer transaction-making practices in many industries. Sellers now attract customers with innovative Internet-based selling mechanisms that can reveal or conceal market information.

This paper expands a model different from existing models to analyze the cost and benefit of areinforced concrete solar chimney power plant (RCSCPP) built in the desert regions of Iran.Based on the model and some assumptions for values of parameters, this paper calculates totalnet present value (TNPV) and the minimum electricity price in each phase by dividing the wholeservice period into four ...

the objective of this study was to determine the effects of hulled and hull-less barley grains’ chemical treatment on disappearance of dry matter (dm), starch and cncps carbohydrate fractions. for barley grain treatment, naoh, formaldehyde and urea were used at 35, 4 and 35 gr/kg dm respectively. three mature rams (one year old) of zel breed were rumen cannulated to calculate ruminal disappeara...

An in vitro experiment was conducted to determine the effect of supplemental non-fiber carbohydrate(NFC) on the disappearance kinetics of cellulose (Ce) by mixed ruminal microorganisms. Non-supplementedor NFC supplemented cellulose (467 mg NFC/g cellulose as sucrose (CeSu) or starch (CeSt) or a 1:1 mixtureof sucrose + starch (CeSuSt)) were incubated for 24, 48, and 96 h at 39°C. After each incu...
