For a microbial ecological analysis, 20 strains of Legionella pneumophila isolated from both unchlorinated Noyu (unattended natural hot spring) samples and chlorinated hot spring bath water samples collected throughout Japan were subjected to a clustering analysis on the basis of a Pulsed-Field Gel Electrophoresis (PFGE) pattern analysis. The PFGE patterns obtained from 19 strains of L. pneumop...

INTRODUCTION Most denture base acrylic resins have polymethylmethacrylate in their composition. Several authors have discussed the polymerization process involved in converting monomer into polymer because adequate polymerization is a crucial factor in optimizing the physical properties and biocompatibility of denture base acrylic resins. To ensure the safety of these materials, in vitro cytoto...

background: the newborn’s first bath, performed in neonatal intensive care units (nicu), is believed to be a stressful situation, especially for the premature infants. as a developmental care approach, swaddle bathing is a low-stress bathing method for vulnerable preterm neonates. given the limited number of the studies examining this bathing method, the present study was conducted with the aim...

The terahertz (THz) range is very attractive for astronomical observations. Spectroscopy and photometry of remote space objects in the THz range allows for a study of their chemical composition, because this range covers rotational lines from simple molecules and electron transition lines from atoms and ions. Heterodyne receivers, due to their high spectral resolution, in the THz range allows f...

The surface composition of as-grown and annealed ZnO nanorods arrays (ZNAs) grown by a two-steps chemical bath deposition method has been investigated by Xray photoelectron spectroscopy (XPS). XPS confirms the presence of OH bonds and specific chemisorbed oxygen on the surface of ZNAs, as well as H bonds on 0) 1 (10 surfaces which has been first time observed in the XPS spectra. The experimenta...

Highly hexagonally ordered hard anodic aluminum oxide membranes, which have been modified by a thin cover layer of SiO2 deposited by atomic layer deposition method, were used as templates for the synthesis of electrodeposited magnetic Co-Ni nanowire arrays having diameters of around 180 to 200 nm and made of tens of segments with alternating compositions of Co54Ni46 and Co85Ni15. Each Co-Ni sin...

Abstract Surfaces of cam shafts made AISI 8620 steels were hardened by boriding processes in both solid and liquid mediums. Various chemical agents used to achieve boride layers on the surfaces these processes. It was aimed examine effects microhardness thickness obtained. concluded that a bath composition 5% B 4 C-90% SiC-5% KBF appropriate for hardest thickest layer achieved medium, 70% Na 2 ...
