Xyloglucan (XG) is the predominant hemicellulose in primary cell wall of superior plants. It has a fundamental role controlling stretching and expansion plant wall. There are five types enzymes known to cleave linear chain xyloglucan, most well-known xyloglucanase (XEG). The immobilization process can be used solve problems related stability, besides economic benefits brought by possibility its...

in this research, the production of plum pastille-like with starch and gelatin was studied. thirteen formulation of plum pastille-like were prepared according to a second-order composite rotatable design (with five central points). response surface methodology (rsm) was used to optimize product formulation with: gelatin concentration ranging from 3.85 to 6.925 % (w/w), and starch concentration ...

Process optimization is essential for the large-scale viability of food industry. Central composite rotational design (CCRD) followed by response surface analysis was used to optimize production fish protein hydrolysate (FHP). FHP obtained from tilapia filet trimmings hydrolyzed subjected using Alcalase 2.4L™, Neutrase™, and Novo-Pro™ D enzymes under temperature, enzyme concentration, pH-contro...

nowadays biodiesel is receiving more attention as a most important renewable energy for using in diesel engines. inthis research, the application of response surface methodology (rsm) was highlighted to investigate the effects of biodiesel-diesel blends (b0, b20, b50 and b100), engine operating parameters (engine load and  speed) on co2 emission of a diesel engine. the experiments were conducte...

Based on composite optical transformation, we propose a rotatable illusion media with positive permittivity and permeability to manipulate terahertz waves, and a new way to realize singular parameter-independent cloaks when the incident wave with a certain width propagates from specific incident directions. The fundamental mechanism of this kind of cloak is that the illusion media can be able t...

Many manufactured products require machining at some stage of their production sequence. Generally, machining ranges from relatively rough cleaning of castings to high-precision micromachining of mechanical components that require narrow tolerances. It is estimated that of all machining processes about 40% pertain to turning. Turning is the most common way for processing rotational (symmetrical...

Celastrol has been found to be a potent anti-inflammatory and antitumor plant derivative recently. Herein we established an accurate reverse phase HPLC (RP-HPLC) determination method of celastrol, and prepared an effective nanoscale drug delivery system from the optimized formulations of celastrol-loaded carboxyl functioned poly(ethylene glycol)-block-poly(propylene glycol)-block-poly(ethylene ...

A preliminary study on statistical modelling of a process for depolymerisation of cassava non-starch carbohydrate using halide salt assisted phosphoric and pyruvic acids were accomplished. The effects of three independent variables namely; acid concentration, potassium iodide salt and duration were studied using the central composite rotatable design on hydrolysis of the cassava non-starch carb...
