  • Problem statement: Dilute sulphuric acid and enzymatic hydrolysis methods were used for sugar extraction. Xylose and glucose sugars were obtained from corn cobs. Approach: Acid hydrolysis of corn cobs gave higher amount of sugars than enzymatic hydrolysis. Results: The results showed that optimal temperature and time for sugar fermentation were approximately 25°C and 50 h by two yeast strains (S. cerevisiae and P. Stipitis) respectively.

  • This report documents a collection of papers on a family of uniform strain tetrahedral finite elements and their connection to different element types. Also included in the report are two papers which address the general problem of connecting dissimilar meshes in two and three dimensions. Much of the work presented here was motivated by the development of the tetrahedral element described in the report 'A Suitable Low-Order, Eight-Node Tetrahedral Finite Element For Solids,' by S. W. Key (ital et al.), SAND98-0756, March 1998.

  • Bacterial strains and culture conditions: Grape pomace is a natural product rich in dietary fiber and polyphenols. A major part of dietary polyphenols is not absorbed in the small intestine and can interact with colonic microbiota. The influence of grape polyphenols on Lactobacillus acidophilus CECT 903 growth was investigated through agar diffusion assays and cultures in liquid media. Grape phenolic extracts and some standards of phenolic compounds (caffeic acid, gallic acid, tannic acid, catechin, epicatechin, and quercetin) were assayed.
