Mutually opposite effects of dopamine.HCl and chlorpromazine. HCl on the thickness of liposomal lipid bilayers.

The aim of this study was to provide a basis for examining the molecular mechanism for the pharmacological action of dopamine.HCl (DA) and chlorpromazin.HCl (CPZ).

Defect study on polyaniline by positron annihilation spectrometry.

Fast coincidence system was constructed and applied to positron annihilation spectrometry (PAS). We studied on the factors that affected the time resolution of the system. Time resolutions were obtained and mutually compared with respect to several factors such as sizes, kinds of scintillators, length dependence of delay lines on the CFD583, and width variations of the windows for 511keV and 1.

Compact soft x-ray transmission microscopy with sub-50 nm spatial resolution.

In this paper, the development of compact transmission soft x-ray microscopy (XM) with sub-50 nm spatial resolution for biomedical applications is described. The compact transmission soft x-ray microscope operates at lambda = 2.88 nm (430 eV) and is based on a tabletop regenerative x-ray source in combination with a tandem ellipsoidal condenser mirror for sample illumination, an objective micro zone plate and a thinned back-illuminated charge coupled device to record an x-ray image.

Characterization of HANARO neutron radiography facility in accordance with ASTM standard E545-91/E803-91 for KOLAS/ISO17025.

As neutron radiography is even more in demand for industrial applications of aircraft, turbine blade, automobile, explosive igniters, etc, it is necessary to review the standards which are the most appropriate for preparing the procedures for setting up the QA system. Recently, Korea Of Lab Accreditation Scheme (KOLAS) was originated from ISO 17025. It is widely recognized by research peer groups for conducting valid tests.
