ABSTRACT: Aqueous enzymatic extraction of oil from pistacia khinjuk was performed using cellulase. The central composite design was used to optimize the parameters that are significant to the process. The influence of three regressors on the percentage of oil recovery from seed was evaluated using second-order polynomial multiple regression model. Analysis of variance showed a high coefficient ...

a 7.5 year-old girl was seeking orthodontic treatment because of severe ectopic eruption of maxillary first permanent molars. it was a rare case that represented approximately horizontal view in panoramic radiograph. the severity of problem was high, but since the patient had maxillary deficiency, it was important to perform the treatment without extraction. treatment began with extraction of u...

In order to identify the parameters of photovoltaic (PV) cells and modules more accurately, reliably efficiently, a chaotic second oscillation JAYA algorithm (CSOOJAYA) is proposed. Firstly, both logical map mutation strategy are brought in enhancing population diversity improving exploitation. Secondly, better balance exploration exploitation, factor added, which not only improves population, ...

A general feature extraction framework is proposed as an extension of conventional linear discriminant analysis. Two nonlinear feature extraction algorithms based on this framework are investigated. The 1rst is a kernel function feature extraction (KFFE) algorithm. A disturbance term is introduced to regularize the algorithm. Moreover, it is revealed that some existing nonlinear feature extract...

Phenol extraction and cesium trifluoroacetate ultracentrifugation were compared for efficiency in the extraction of DNA from eggs and second-stage juveniles of four species of Meloidogyne. The second method proved to be more satisfactory in that it yielded larger amounts of DNA, shortened the extraction period, and reduced sample handling by eliminating phenol and ether extraction and RNAse tre...
