This paper presents a PC-based PCR thermal cycler with a host-local architecture, where a PC is employed as the host. The local system only executes the thermal cycling process and the PC is responsible for the management of PCR protocols with a convenient GUI. The presented host-local system greatly reduces the development time and the maintenance cost, providing an economical PCR thermal cycler.

We presented a novel platform for an ultrafast PCR system, called the Rotary PCR Genetic Analyzer, which incorporates a thermal block and resistive temperature detector (RTD) for thermal cycling control, a disposable PCR microchip, and a stepper motor. The influenza viral RNAs from H3N2, H5N1, and H1N1 were simultaneously identified with high sensitivity and speed.

objective: optimal dentin bonding is not always obtained in clinical practice due to func-tional forces. these forces may provide stresses throughout the tooth and restorative sys-tem, which in turn may affect the adhesive bond. this experimental study evaluated the effect of load cycling on bond strength of self-etch systems. materials and methods: one third of the coronal portions of 48 intac...

BACKGROUND Glass-ionomer cements perform a protective effect on the dentin-pulp complex considering the F ions release and chemical bonding to the dental structures. On the other hand, those materials have poor physic-mechanical properties in comparison with the restorative resin composite. The main aim of this work was to evaluate the influence of zirconia and/or alumina fillers on the microst...

PURPOSE This study assessed the shear bond strength of 4 hard chairside reline resins (Kooliner, Tokuso Rebase Fast, Duraliner II, Ufi Gel Hard) to a rapid polymerizing denture base resin (QC-20) processed using 2 polymerization cycles (A or B), before and after thermal cycling. MATERIALS AND METHODS Cylinders (3.5 mm x 5.0 mm) of the reline resins were bonded to cylinders of QC-20 polymerize...

A general method for brazing ceramics to metals using a compliant metallic foam as a buffer layer has been developed. Using stainless steel foams, bonds between alumina and 316 stainless steel with shear strengths up to 33 MPa have been achieved. The resultant ductility enhances the resistance of the joint to thermal cycling; AlN-Inconel 600 bonds exhibited good thermal shock resistance. Alumin...

Title of Document: EVALUATION OF THERMAL INTERFACE MATERIALS AND THE LASER FLASH METHOD Vinh Khuu, Doctor of Philosophy, 2009 Directed By: Chair Professor, Michael Pecht, Department of Mechanical Engineering Thermal interface materials (TIMs) are used to reduce the interfacial thermal resistance between the chip and the heat sink, which has become a bottleneck to heat removal in a variety of el...

This article shows how fractures in the Si3N4 layer, which comprises top layer of semiconductor devices encapsulated utilizing a lead-on-chip (LOC) packaging technique, are influenced by changes lead-frame materials and thermal-cycling test conditions. Using tests, it was found that Si 3 N 4 most sensitive to at early stage thermal-cycling, between -65sup>oC 150sup>oC. Through SEM examina...

The fatigue growth of a fiber reinforced composite laminate was characterized under thermal cycling using a combined experimental and computational investigation. Twenty-four ply composite laminates (1⁄20 12=90 12 ) are fabricated with a pre-existing delamination, and subjected to thermal cycling in an environmental chamber. The large mismatch in the coefficients of thermal expansion is used to...
