This paper presents the development and application of a heat transfer inversion procedure to the cure of thermoset based composites based on genetic algorithms. The procedure is utilized for process optimization applied to the curing of carbon fiber reinforced composites. The optimization objective is the selection of an appropriate cure schedule so that the duration of the curing is minimized...

Novel, effective methods to control and prevent spoilage and contamination by pathogenic microorganisms in meat and meat products are in constant demand. Non-thermal pasteurization is an ideal method for the preservation of meat and meat products because it does not use heat during the pasteurization process. Atmospheric pressure cold plasma (APCP) is a new technology for the non-thermal pasteu...

A comparison was made on the mechanical properties of three glass-ionomer cements, one of which was of experimental fiber-reinforcing and auto-curing type. Two others were proprietary auto-curing and light-activating cements. Biaxial flexure test was conducted on disc samples. Three-point bending test was also carried out on bar samples to determine modulus of elasticity and strength. All sampl...

Rapid destruction of carotene occurs in alfalfa during the field curing process. The loss under good curing conditions may be 45 to 80 per cent of the carotene originally present (14). Hauge and Aitkenhead (5) and Hauge (6) presented evidence which indicates the presence of a carotenedestroying enzyme system in alfalfa. The belief that the destruction of carotene during field curing may be larg...

This investigation aims at determining the microhardness value of the hybrid direct/indirect composite resins submitted to conventional light curing and post-cured using two different methods, a light source from a laboratory light curing unit and a conventional oven heating, and the obtained results were compare to an indirect composite resin. A hybrid direct/indirect composite resin (Filtek P...

Portland cement concrete (PCC) has been successful in many applications. However, since the 1960s technological investigations concerning modifications of concrete by polymeric materials have been conducted. Attention has been focused on concretes in which the continuous phase is some kind of polymeric resin and the discrete phase is some type of mineral aggregate. Such composite materials are ...

Abstract—Through use of novel modern/rapid processing techniques such as screen printing and Near-Infrared (NIR) radiative curing, process time for the sintering of sintered nickel plaques, applicable to alkaline nickel battery chemistries, has been drastically reduced from in excess of 200 minutes with conventional convection methods to below 2 minutes using NIR curing methods. Steps have also...

If the chemical guanidine hydrochloride is added to a dividing culture of yeast cells that carry a yeast prion, the proportion of cells that have the prion gradually decreases over time. Stochastic models to describe this process of ‘curing’ have been developed in earlier work. The present paper investigates the use of numerical Laplace inversion methods to calculate curing curves and contrasts...
