In Thailand, RSS chamber of community-level rubber cooperatives can be classified into two models: old and new model, named after the years of their establishment. Hot gas as a heat supply from Para-rubber (PR) wood (Hevea brasiliensis) combustion is used for removing moisture from the natural rubber (NR) sheets. Smoke and soot particles from PR wood burning has effected to the quality of the N...

We show how to determine the ratio of the transverse velocity of a source to the velocity of emitted particles, using split–bin correlation functions. The technique is to measure S2 and S φ 2 , On leave until 12 October 1993 at: Theory Division, CERN, CH–1211 Geneva 23, Switzerland; Internet: [email protected]. Internet: [email protected].

The diffusion decision model (Ratcliff, 1978) was used to examine discrimination for a range of perceptual tasks: numerosity discrimination, number discrimination, brightness discrimination, motion discrimination, speed discrimination, and length discrimination. The model produces a measure of the quality of the information that drives decision processes, a measure termed drift rate in the mode...

A technique for measuring the instantaneous deformation rate of hydrogel microstructures is introduced. In developing this technique, we have adapted microscopic particle image velocimetry, a method for measuring velocity fields in microfluidic devices. Small fluorescent seed particles are incorporated into the hydrogel microstructure, and as the structure swells or contracts, the displacement ...

BACKGROUND Symmetry is one of the criteria of achieving a good aesthetic result. Realising this can be difficult. Attempts have been made to try and measure this symmetry using advanced and complex methods.1 For most surgeons on a daily basis the only practical way to measure symmetry is to use a simple measuring tool such as a measuring tape. However, this method is not very reliable as it dep...

BACKGROUND Adequate application of the static and dynamic anthropometric measures of pre-school children in ergonometric design of children's playground equipment should eliminate all dangers and difficulties in their use. Possibilities of injuries, insecure movements, discomfort able positions and some other dangerous actions may be minimized; and safety and health protection of pre-school chi...

statement of the problem addition of metallic nano-particles to composite resins can change their water contact angle purpose the aim of this study was to evaluate the effect of addition of nano-particles of silver and zinc oxide to composite resins on their water contact angle materials and methods this in vitro study was performed on 60 composite resin samples. nano-silver and nano-zinc oxide...

lta zeolite nanoparticles was successfully synthesized from clear solution under controlled conditions using hydrothermal method using tetramethyl ammonium hydroxide as a structural directing agent. the as-synthesized lta zeolite particles were characterized by powder x-ray diffraction (xrd) analysis, scanning electron microscopy (sem), fourier transform infrared (ft-ir) spectroscopy, energy di...

We discuss the characteristic interference features of soft radiation in the threshold production of heavy unstable particles: soft gluon radiation in e+e− → tt̄ and soft photon radiation in e+e− → W+W−. We show that the heavy particle decay width controls the interference between the emission off the final state particles. As a result, the radiation pattern may provide a way of measuring the de...
