Traditional kombucha is a fermented black tea extract and sugar. Sweetened black tea (10% w/v) and wheatgrass juice (WGJ) were mixed in various ratios and used as fermentation substrate for enhancing phenolic compounds and antioxidant activity. Starter, comprising of yeast (Dekkera bruxellensis) and acetic acid bacteria Gluconacetobacter rhaeticus and Gluconobacter roseus), was inoculated at 20…
The advertising budget allocation problem for financial service is dealt with based on statistical learning and evolutionary computation in this paper. Taking the carry-over effects of the advertising into account, the least squares support vector machine regression (LS-SVMR) is used to construct the response model. A comparison between the proposed response model and traditional regressionmeth…
In this paper, we use satellite data to test the hypothesis that deep convection moistens the lower stratosphere. Water vapor measurements from Earth Observing System-Microwave Limb Sounder and Atmospheric Chemistry Experiment-Fourier Transform Spectrometer over North America are binned according to the International Satellite Cloud Climatology Project deep convection indices. The results sh…
In this article, the microstructures of sisal fiber composites were analyzed. The porous structure of sisal fiber, crystalline morphology of matrix and fiber distribution in composites were haracterized by Voronoi diagram. The tensile properties of composites were also measured. The results show that the maleated polypropylene compatibilizer can accelerate the formation of transcrystalline inte…
