Three categories of capability include technological processing capability‚ physical size and weight‚ and production capacity. ____________________________________________________________ _________ 4. How does a shaping process differ from a surface processing operation? Answer. A shaping process changes the geometry of the work material (machining or forging). A surface processing operation does not alter the geometry‚ but instead alters the properties and/or

Vanillin was first synthesised from eugenol from 1874 – 2001‚ from where it was later made from lignin- containing sulphite liquor which is a by-product of wood pulp processing in paper pulp manufacturing‚ most recently it is more common to find vanillin made from guaiacol and glyoxlic acid (3D chem‚ 2013). Vanillin is most commonly found in food flavour formulations‚ perfumes and fragrances and has been used in drugs used by those who suffer from Parkinson’s disease (RHODIA‚ 2013). Physical State |

Practical 1 Title: Tissue Processing Aim: To examine human cell and tissue under the microscope Introduction: Tissues from the body taken for analysis of diseases must be processed in the histology laboratory to produce microscopic slides that are viewed under the microscope. These tissues are usually fixed into paraffin. Microscopic analysis of cells and tissues requires the preparation of very thin‚ high quality sections mounted on glass slides and properly stained to demonstrate normal and abnormal

IB1 Chemistry Practical #8 ANALYSIS OF ASPIRIN TABLETS For a long time the bark of the willow tree (salix alba) was used as a traditional medicine to relieve the fever symptoms of malaria. In the 1860’s chemists showed that the active ingredient in willow bark is salicylic acid (2-hydroxybenzoic acid) and by 1870 salicylic acid was in wide use as a pain killer (analgesic) and fever depressant (antipyretic). However‚ because it is a relatively strong acid‚ salicylic acid has the undesirable side effect
