OBJECTIVES The evaluation of Mutans streptococci (MS) is one of the index for caries risk. Dentocult(TM) and CRT(TM) are commercial kits to detect and evaluate MS, conveniently. However, the evaluation of MS has also been carried out simply using an instruction manual. But the instruction manual is not easy to use for evaluation of MS. The aim of this study was to examine the utility of modifie...

In this paper we study the possibility of utilizing a loaded wire medium as an artificial material for beam shaping element in base station antenna applications. The wires in the lattice are loaded with a proper capacitive impedance to come up with a structure effectively operating as a dielectric lens at the UMTS (Universal Mobile Telecommunications System) frequency range. It is proven with f...

influence extracellular acid–base status in brachyuran decapod crustaceans (Truchot, 1973; Truchot, 1981; Truchot, 1992; Mangum et al., 1976; Henry and Cameron, 1982; Wheatly, 1985). Although the underlying mechanisms and the physiological consequences remain unclear, the basis for the relationship between acid–base status and ion regulation can be attributed to the catalysed hydration of CO2 b...

The effect of abscisic acid (ABA) and excess benzyladenine (BA) on the formation of shoot from tea (Camellia sinensis L. assamica × sinensis) leaf was investigated in this research. Callus was formed and grew well when explants were cultured on LS basal medium supplemented with (in mg/L) thiamine-HCl, 1.25; pyridoxine-HCl, 0.625; nicotinic acid, 0.625; indole-3-acetic acid (IAA), 30; naphthalen...

zinc oxide nano-particles with the average diameter of about 25 nm were modified with different mole ratios of trimetoxyvinyl silane (tmvs) and oleic acid, as coupling agents, in order to modify their surface properties and render them more hydrophobic. then, dispersibility of the surface modified nano-particles was examined in some monomers with different levels of hydrophobicity, including me...

The performance of depth reconstruction in binocular stereo relies on how adequate the predefined baseline for a target scene is. Widebaseline stereo is capable of discriminating depth better than the narrow one, but it often suffers from spatial artifacts. Narrow-baseline stereo can provide a more elaborate depth map with less artifacts, while its depth resolution tends to be biased or coarse ...
