6. On the Influence of Mixing and Scaling-Up in Semi-Batch Reaction Crystallization
Abstract : Semi-batch crystallization experiments have been performedboth in a loop reactor and in stirred tank reactors.Hydrochloric acid was fed to a stirred solution of sodiumbenzoate, and benzoic acid immediately formed. Benzoic acid isformed in excess of the solubility making the solutionsupersaturated.The loop reactor is U-shaped. READ MORE

7. The influence of high temperature on the discoloration and degradation of carbohydrates and on hydrogen peroxide bleaching of spruce TMP
Abstract : When processing wood to obtain pulp, the fibers are subjected to high temperatureat moisture levels and to the influence of metal ions. Many process developmentshave resulted in utilization of higher temperatures that induce chemical reactionsin the wood fibers. This thesis deals with some aspects of using high temperaturesin pulping processes. READ MORE

8. Gastric acid secretion and gut peptides : mechanisms involved in inflammatory response
Abstract : The regulation of gastric acid secretion is complex and involves endocrine, paracrine, and neurocrine mechanisms. Among these, the interconnecting cross-talk between different gut peptides is an important part in the control of acid secretion. READ MORE

9. Effects of nitric oxide on gastric acid secretion in human gastric mucosa : functional and morphological studies
Abstract : Hydrochloric acid (HCI) is secreted in high amounts by parietal cells in the human gastric mucosa and the resulting low pH constitutes an important factor for creating a suitable environment for the digestion. The normal gastric mucosa is equipped with an arsenal of protective mechanisms against the extreme chemical environment which the gastric acid creates. READ MORE

10. Recovery of copper and zinc in ashes from municipal solid waste combustion
Abstract : The amount of municipal solid waste incineration (MSWI) fly ash has increased in many parts of the world in recent years. Ashes from municipal solid waste incineration (MSWI) may be a cumbersome waste to handle since containing significant amounts of leachable hazardous metal species and must be landfilled in special sites at high costs.
