Residues from the food industry are a problem worldwide. Alternatives have been developed in an attempted to extract compounds from fruit pomace in other to apply those as a natural component in different products. This work has the objective to produce two extracts: (1) ethanolic extract and (2) hot water extract; and characterize the chemical composition of these extracts for future applicati...

The impact of Tween20 surfactant, applied in native form or as colloidal gas aphrons (CGAs), on the extractability/purification enhancement antioxidant compounds from grape skins (GS), compared to conventional solid–liquid extraction (SLE), was evaluated. Three strategies were developed (S1: partial ethanol replacement during SLE with aqueous solutions; S2: CGAs application GS-extract suspensio...

efforts to increase the mass transfer coefficient, enhance the contact area, and decrease the power input of contractors have given risen to the development of the pre-dispersed solvent extraction (pdse) contactor and the devise of the new dissolved nitrogen pdse (dnpdse) contactors. the studies conducted after the design of the new contactor to determine the working conditions for its suitable...

Colloidal Gas Aphron as a mobility control in enhanced oil recovery is becoming attractive; it is also designed to block porous media with micro-bubbles. In this paper, the effects of surfactant concentration, polymer concentration, temperature and salinity on the bubble size of the Colloidal Gas Aphron were studied. Effects of injection rates, Colloidal Gas Aphron fluid composition, heterogene...

32 33 Chromogranin A (CgA) is widely expressed in endocrine and neuroendocrine tissues as well as in the central 34 nervous system. We observed CgA expression (mRNA and protein) in the gastrocnemius (GAS) muscle and 35 found that performance of CgA-deficient Chga-KO mice in treadmill exercise was impaired. Supplementation 36 with CgA in Chga-KO mice restored exercise ability suggesting a novel ...

– We consider a toy model for glassy dynamics of colloidal suspensions: a single Brownian particle diffusing among immobile obstacles. If Gaussian factorization of static density fluctuations is assumed, this model can be solved without factorization approximation for any dynamic correlation function. The solution differs from that obtained from the ideal mode coupling theory (MCT). The latter ...
