A relatively steady resting potential in the extirpated eyeball of cold-blooded animals was independently discovered and reported by Holmgren3" 4 and by Dewar and McKendrick7 more than a half-century ago. Later investigators, among them Kuhne and Steiner,2' Waller,32 Gotch," Bossa and Kohlrausch,2 and Kohlrausch,19 extended the observations on this subject by various studies on several animal f...

It is shown that accurate values of the rates of enthalpy generation in the electrolysis of light and heavy water can be obtained from measurements in simple, single compartment Dewar type calorimeter cells. This precise evaluation of the rate of enthalpy generation relies on the nonlinear regression fitting of the “black-box” model of the calorimeter to an extensive set of temperature time mea...

The results of engineering an intelligent preamplifier for high purity germanium gamma-detectors are presented. An is a low-noise, speed resistive feedback charge-sensitive with built-in microcontroller and additional units that enable control detector parameters. It also allows the performance managing internal testing pulser, sensor liquid nitrogen level in Dewar, humidity, pressure temperatu...

BL-5C is an in-vacuum undulator beamline dedicated to macromolecular crystallography (MX) at the 3 GeV Pohang Light Source II in Korea.

Protein binding and function often involves conformational changes. Advanced nuclear magnetic resonance (NMR) experiments indicate that these conformational changes can occur in the absence of ligand molecules (or with bound ligands), and that the ligands may "select" protein conformations for binding (or unbinding). In this review, we argue that this conformational selection requires transitio...

In this paper we present our system design and methodology for making absolute quantum efficiency (QE) measurements through the vacuum ultraviolet (VUV) and verify the system with delta-doped silicon CCDs. Delta-doped detectors provide an excellent platform to validate measurements through the VUV due to their enhanced UV response. The requirements for measuring QE through the VUV are more stre...

We discuss a possible new resonance in active-sterile neutrino oscillations arising in theories with large extra dimensions. Fluctuations in the brane effectively increase the path-length of active neutrinos relative to the path-length of sterile neutrinos through the extra-dimensional bulk. Well below the resonance, the standard oscillation formulas apply. Well above the resonance, active-ster...

In this study, the adsorption of 4-hydroxy phenyl-azobenzene on the surface of (4, 0) zigzag open-end boron nitride nanotube (BNNT) has been investigated by quantum calculations. In order to find the preferred adsorption site, different positions and orientations were considered. The impacts of donor-acceptor electron delocalization on the structural and electronic properties and reactivity of ...
