review of medical biosensors and associated materials problems

developers of biosensors as medical devices are using emerging technologies that incorporate chemical assays with fiber optics and semiconductors. these biosensors will eventually become indwelling cathers for monitoring blood analyte concentrations as well as functioning as controlled feedback elements for artificial organs materials use..

newer uses of microbial enzymes in food processing

microbial enzymes are widely used in food processing; many new enzymes and enzyme processes acting on nearly all types of organic food components - starch, sugars, proteins, fats, fibers, and flavor compounds - have come into the industry during the 1980s and their application has a major impact on enzyme technology in general. the partic..

mechanical finishing of stainless steel fabrications

various surface treatments used for mechanical finishing of stainless steel (sheet, plate, tubes) are described. tensile strength, surface hardness, thermal conductivity and work hardening properties of the steel affect the finishing process to be used, as do the reasons for finishing (aesthetic, hygiene, corrosion resistance). surface fi..

correlations of processing variables for optimizing the pultrusion process

an innovated pultrusion equipment which includes a fiber drying chamber, a preheated resin tank, a pultrusion die with multiple heating zones and a post-cure chamber has been designed and studied the improvement of this design on pultrusion rate and the properties of pultruded part is reported. the influences of the type and loading level..

effect of the state of the surface layer on the hydroabrasive wear resistance of hydroturbine steel

it has already been demonstrated that the ability of flow section elements in hydroturbines to withstand damage depends not only on the corrosion-mechanical properties of the material used, but also on the physicochemical state of the metal in their surface layer that results from the methods and conditions of the finishing treatment used..

design life of buildings

this symposium proceedings contains 21 papers. the topics covered include: building durability and design life; factors affecting concrete structure durability; prestressed concrete member durability; building degradation causes; blast resisting structure design; temporary structure service life; building material long term behavior; glas..

fibre-optic sensors in biomedical sciences

the principles of waveguide spectroscopy are briefly outlined, and representative examples of fiber-optic sensors for temperature, oxygen, ph, carbon dioxide and electrolytes are given. apart from these parameters, which also may be sensed by other techniques, optical sensors have been developed that are based on new principles and which ..

plenary lectures presented at the second international symposium on quantitative luminescence spectrometry in biomedical sciences

proceedings consists of five papers on quantitative luminescence spectrometry in biomedical sciences. topics include: use of luminescence in high performance liquid chromatography; chemiluminescent compounds for clinical analysis; chemiluminescence enzyme immunoassay; protons transfer kinetics of photoexcited hydroxyaromatics; and fiber o..

hot oil pipeline fabrication

a new design for line pipe used in the subsea transmission of oil at elevated temperatures relies on submerged arc welding. the new design was developed by bredero price international b. v. in kuantan, malaysia, with assistance from lincoln electric co. the pipes are separated by a space in which a polyurethane foam has been pumped. the f..
