Sporogonic development of cultured Plasmodium falciparum in six species of laboratory-reared Anopheles mosquitoes
(American Society of Tropical Medicine and Hygiene, 1994)
Sporogonic development of cultured Plasmodium falciparum was compared in six species of Anopheles mosquitoes. A reference species, A. gambiae, was selected as the standard for comparison. Estimates of absolute densities ...
DNA probes for detection of copper resistance genes in Xanthomonas campestris pv. Vesicatoria
(American Society for Microbiology, 1991-08)
The copper resistance (Cu^r) genes encoded on pXV1OA, a 190-kb plasmid in Xanthomonas campestris pv. vesicatoria XV10, were isolated on a 44-kb cosmid clone designated pCuRl. TnS mutagenesis of pCuRl indicated that a 4.0-kb ...
Expression of the strA-strB streptomycin resistance genes in Pseudomonas syringae and Xanthomonas campestris and characterization of IS6100 in X. campestris
(American Society for Microbiology, 1995-08)
Expression of the strA-strB streptomycin resistance (Sm^r) genes was examined in Pseudomonas syringae pv. syringae and Xanthomonas campestris pv. vesicatoria. The strA-strB genes in P. syringae and X. campestris were encoded ...
Carrier dynamics of electrons and holes in moderately doped silicon
(American Physical Society, 1990-06-15)
A time-domain spectroscopic technique, based on the generation and detection of a collimated beam of subpicosecond broadband terahertz pulses, is used to measure the absorption and dispersion of n- and p-type silicon, with ...
Experimental time-domain study of THz signals from impulse excitation of a horizontal surface dipole
(AIP Publishing, 1999-03-22)
Using optoelectronic techniques with sub-ps resolution, we have characterized the electric-field time-domain response from an impulsively excited, micron-sized dipole antenna on a dielectric surface. When detected by an ...
Concentration of human erythrocytes by anopheline mosquitoes (Diptera: Culicidae) during feeding
(Oxford University Press (OUP), 1991-11)
Erythrocyte densities in the blood meals of six Anopheles mosquito species were compared with those of human host erythrocyte densities. During engorgement, An. gambiae Giles and An. stephensi Liston concentrated erythrocytes ...
Optical and electronic properties of doped silicon from 0.1 to 2 THz
(AIP Publishing, 1990-04-23)
Using a source of freely propagating subpicosecond pulses of THz radiation, we have measured the absorption and dispersion of both N- and P-type, 1 ohm-cm silicon from 0.1 to 2 THz. These results give the corresponding ...
Attaching boundary planes to irreducible open 3-manifolds
(Oxford University Press (OUP), 1996)
Measurements of the THz absorption and dispersion of ZnTe and their relevance to the electro-optic detection of THz radiation
(AIP Publishing, 1999-06-07)
Via THz time-domain spectroscopy, we have measured the absorption and index of refraction of single-crystal (110) ZnTe from 0.3 to 4.5 THz. We find that the absorption is dominated by two lower-frequency phonon lines at ...
Predicting key malaria transmission factors, biting and entomological inoculation rates, using modelled soil moisture in Kenya
(Wiley, 1998-10)
While malaria transmission varies seasonally, large inter-annual heterogeneity of malaria incidence occurs. Variability in entomological parameters, biting rates and entomological inoculation rates (EIR) have been strongly ...
