The Chemistry of Tea Manufacture
The chemical changes that occur in the various stages of tea manufacture were. until recently, imperfectly known. Research in this direction would help not only in improving the existing methods of manufacture, but also in the solution of any ... fresh problems as they arise. In order to render the present manufacturing practices scientific rather than empirical, a thorough knowledge of the che...
متن کاملDevelopment of a Continuous Finishing Chemistry Process for Manufacture of a Phosphorylated Cotton Chronic Wound Dressing
A phosphorylated form of cotton gauze for treatment of chronic wounds was designed to improve the wound dressing’s capacity to remove harmful proteases from the wound and facilitate healing. Development of the fabric finishing chemistry of the wound dressing with a process suitable for textile mill production required adapting the stationary finishing chemistry of the cotton phosphorylation fro...

متن کاملManaging traceability information in manufacture
In this paper an approach to design information systems for traceability is proposed. The paper applies gozinto graph modelling for traceability of the goods flow. A gozinto graph represents a graphical listing of raw materials, parts, intermediates and subassemblies, which a process transforms into an end product, through a sequence of operations. Next, the graphical listing has been translate...
متن کاملHazardous agents in anode manufacture.
The aim of this study was to assess to which extent the modernisation of an anode plant had reduced occupational chemical health hazards for jobs with the highest potential of exposure. Periodical measurements of dust and gases were performed at the same workplaces using the same methods, before and after modernisation. These measurements were compared with the recommended standards. Before mod...
