An additional PIIinEscherichia coli: a new regulatory protein in the glutamine synthetase cascade

Wally C. van Heeswijk、Brenda I. Stegeman、Sjouke Hoving 等 6 位作者1995-10-01FEMS Microbiology Letters

The PII protein in the glutamine synthetase cascade transduces the nitrogen signal, as sensed by uridylyltransferase, both to the NRII/NRI two-component system and to adenylyltransferase, to regulate the activity of glutamine synthetase. Here we describe the amplification of a chromosomal DNA fragment from Escherichia…

Partial intensity analysis (PIA) for quantitative electron spectroscopy

Wolfgang Werner1995-10-01Surface and Interface Analysis

Abstract An approach is developed to separate the spectral contributions of electrons that have experienced a certain number of inelastic collisions and together constitute the observable lineshape in AES/XPS. The only assumption concerning the emission process that is made in this general approach is that energy loss…

Dimeric 3‐Phosphoglycerate Kinases from Hyperthermophilic Archaea

Daniel Heß、Kerstin Krüger、Achim Knappik 等 5 位作者1995-10-01European Journal of Biochemistry

The gene coding for the 3-phosphoglycerate kinase (EC 2.7.2.3) of Pyrococcus woesei was cloned and sequenced. The gene sequence comprises 1230 bp coding for a polypeptide with the theoretical M(r) of 46,195. The deduced protein sequence exhibits a high similarity (46.1% and 46.6% identity) to the other known archaeal…

Transient photocurrent in amorphous selenium and nematic liquid crystal double layers

Shuichi Murakami、Hiroyoshi Naito、Masahiro Okuda 等 4 位作者1995-10-01Journal of Applied Physics

Transient photocurrents in amorphous selenium (a-Se) and nematic liquid crystal (NLC) double layers have been investigated to elucidate the charge carrier transport process in NLC. It is shown that the transient photocurrents obtained in the experiment are space-charge limited currents induced by the delayed charge in…

Preparation of Dense BaTiO 3 Ceramics from Sol‐Gel‐Derived Monolithic Gels

Hirokazu Shimooka、Makoto Kuwabara1995-10-01Journal of the American Ceramic Society

Dense, small‐grained BaTiO 3 ceramics, with a grain size around 1 μm and a relative sintered density >98%, were obtained at 1100°C from sol‐gel‐derived gel monoliths without using any sintering additives. The monolithic gels asprepared had a relative density of about 50% and consisted of ultrafine pseudo‐cubic BaTi…

Ca Segregation to Basal Surfaces in α‐Alumina

Wayne D. Kaplan、Harald Mxillejans、M. Rühle 等 5 位作者1995-10-01Journal of the American Ceramic Society

High‐resolution transmission electron microscopy (HRTEM) and analytical electron microscopy (AEM) were used to investigate the structure and chemistry of (0001) α‐A1 2 O 3 / A1 interfaces in melt‐infiltrated polycrystalline alumina composites. HRTEM revealed an interfacial region different from both Al and α‐A1 2 O 3…

Luminescence Property of the Terbium Bipyridyl Complex Incorporated in Silica Matrix by a Sol‐Gel Method

Tetsuro Jin、Shuji Tsutsumi、Yujiro Deguchi 等 5 位作者1995-10-01Journal of The Electrochemical Society

Slica‐based composite materials incorporated with a terbium bipyridyl complex, SiO 2 : Tb ( bpy ) 2 3 + , were prepared by a sol‐gel method. The thermal stability of Tb ( bpy ) 2 3 + was improved by incorporation into the silica matrix, and its green emissiom lines were intensified by heat‐treatments under appropriate…

A Novel Solid Oxide Fuel Cell System Using the Partial Oxidation of Methane

Koki Asano、Takashi Hibino、H. Iwahara1995-10-01Journal of The Electrochemical Society

A novel solid oxide fuel cell (SOFC) system, which does not need to separate the supply of fuel and oxidant gases and generates electric power as well as chemicals, was studied. The fuel cell consisted of Pt | BaCe 0.8 Y 0.2 O 3 − α | Au , in which two electrodes were exposed to the same mixture of CH 4 and air. Elect…

Wetting of fiber mats for composites manufacturing: I. Visualization experiments

Yung‐Tin Chen、H. T. Davis、Christopher W. Macosko1995-10-01AIChE Journal

Abstract Wetting of glass fibers was visualized using an oil with the same refractive index. With both a video‐enhanced microscope and a high‐magnification video camera we followed the flow front and qualitatively measured the entrapped air bubbles by image analysis. Due to different permeabilities between the fiber m…
