Iran’s vast common natural gas resources and the necessity to extract and export it as Liquefied Natural Gas (LNG) to distances more than 3000Km opens a lucrative field for researchers to optimize LNG cycles. In this article heat integration in cryogenic cycles by determining interacycle partition temperature and optimizing refrigeration features like Subcooler, Presaturator, aftercooler, reboi...

Optimization of carnosine and anserine extraction from chicken breast was performed using response surface methodology (RSM) to obtain the maximized physiological activities for anti-glycation and anti-oxidation. The optimum extraction conditions were water extraction for 1.6 h in the case of the 20-wk laying hen muscle and water extraction for 2.12 h in the case of 90-wk laying hen muscle. Hig...

hydroalcoholic extract of pycnocycla spinosa was shown to have spasmolytic action in vitro and antidiarrhoeal effect in vivo . the hydroalcoholic extract of p. spinosa is composed of alkaloid, flavonoid and saponin components. alkaloid fraction of p. spinosa contains the most active constituents. therefore, the aim of this research was to separate different fractions of alkaloid extract of p. s...

Background & Aim: Restrictions on the use of synthetic antioxidant such as butylated hydroxyanisole (BHA) and butylated hydroxytoluene (BHT) are being imposed because of their carcinogecity . Experimental: In this investigation, optimization of phenolic extraction process from methanolic (80%) extract (v/v) of  Flomideschema parviflorum through response surface methodology by Fulin Ci...

The objective of the present work is to extract lovastatin with minimum impurity by using supercritical carbon dioxide (SC-CO2). A strain of Aspergillus terreus UV 1617 was used to produce lovastatin by solid-state fermentation (SSF) on wheat bran as a solid substrate. Extraction of lovastatin and its hydroxy acid form was initially carried out using organic solvents. Among the different screen...

Compiler courses have been an academic mainstay in both undergraduate and graduate computer science departments. These courses emphasize either the implementation of languages or parallel processing. Little analysis is...

A problem which often arises while fitting implicit polynomials to 2D and 3D data sets is the following: Although the data set is simple, the fit exhibits undesired phenomena, such as loops, holes, extraneous components, etc. Previous work tackled these problems by optimizing heuristic cost functions, which penalize some of these topological problems in the fit. This paper suggests a different ...

We present a novel approach called Minimal Reconstruction Bias Hashing (MRH) to learn similarity preserving binary codes that jointly optimize both projection and quantization stages. Our work tackles an important problem of how to elegantly connect optimizing projection with optimizing quantization, and to maximize the complementary effects of two stages. Distinct from previous works, MRH can ...
