Influence of light on bacterioplankton production and respiration in a subtropical coral reef
(Inter Research, 1998-02-13)
The influence of sunlight on bacterioplankton production [14C-leucine (Leu) and 3H-thymidine (TdR) incorporation; changes in cell abundances] and O2 consumption was investigated in a shallow subtropical coral reef located ...
Observation of a Cole-Davidson type complex conductivity in the limit of very low carrier densities in doped silicon
(AIP Publishing, 1998-05-04)
Using THz time-domain spectroscopy to measure the complex conductivity of doped silicon from low frequencies to frequencies higher than the THz plasma frequency and the carrier damping rate, we were able to show in the ...
Electrical characterization to 4 THz of N- and P-type GaAs using THz time-domain spectroscopy
(AIP Publishing, 1992-08-17)
Using a high-performance optoelectronic THz beam system for time-domain spectroscopy, we have measured the absorption and index of refraction of N- and P-type doped GaAs from low frequencies to 4 THz. From these measurements ...
Low temperature epitaxial silicon film growth using high vacuum electron-cyclotron-resonance plasma deposition
(AIP Publishing, 1995-05-08)
We report on the growth technique and electrical properties of epitaxial Si films grown at low temperatures using an electron‐cyclotron‐resonance plasma deposition technique. We have used standard high vacuum apparatus to ...
Ingestion of Plasmodium falciparum sporozoites during transmission by anopheline mosquitoes
(American Society of Tropical Medicine and Hygiene, 1992)
We investigated the process of sporozoite transmission during blood feeding for Anopheles gambiae and An. stephensi experimentally infected with Plasmodium falciparum. When infective mosquitoes were fed 22-25 days postinfection ...
Schottky-based band lineups for refractory semiconductors
(AIP Publishing, 1995-04-10)
An overview is presented of band alignments for small-lattice parameter, refractory semiconductors. The band alignments are estimated empirically through the use of available Schottky barrier height data, and are compared ...
XANES and EXAFS study of a platinum phthalocyanine
(Royal Society of Chemistry, 1994)
Extended X-ray absorption fine structure (EXAFS) and X-ray absorption near-edge structure (XANES) studies on [octa(2-ethylhexyloxy)phthalocyaninato]platinum [PtL] as a film at room temperature suggest that the structure ...
Line-shape transition of collision broadened lines
(American Physical Society, 1995-02-20)
Using the newly developed technique of THz time-domain spectroscopy, we have measured the far-wing absorption line profile of the ensemble of collision broadened ground state rotational lines of methylchloride vapor out ...
Copper as a signal for alginate sythesis in Pseudomonas syringae pv. Syringae
(American Society for Microbiology, 1995-06)
Plant-associated pseudomonads are commonly exposed to copper bactericides, which are applied to reduce the disease incidence caused by these bacteria. Consequently, many of these bacteria have acquired resistance or tolerance ...
Determination of the Wigner function from photon statistics
(De Gruyter Open, 1999-08)
We present an experimental realisation of the direct scheme for measuring the Wigner function of a single quantized light mode. In this method, the Wigner function is determined as the expectation value of the photon number ...
