Contractible open 3-manifolds with free covering translation groups
(Elsevier, 1996)
This paper concerns the class of contractible open 3-manifolds which are "locally finite strong end sums" of eventually end-irreducible Whitehead manifolds. It is shown that whenever a 3-manifold in this class is a covering ...
Pseudomonas syringae phytotoxins: Mode of action, regulation, and biosynthesis by peptide and polyketide synthetases
(American Society for Microbiology, 1999-06)
Plasmodium falciparum: The population structure of mature gametocyte cultures has little effect on their innate fertility
(Elsevier BV, 1994)
In vitro cultured Plasmodium falciparum gametocytes were fed to Anopheles gambiae (G3) mosquitoes to identify parasite population characteristics useful for predicting successful mosquito infections. Parameters were collected ...
Exflagellation responses of cultured Plasmodium falciparum (Haemosporida: Plasmodiidae) gametocytes to human sera and midguts of anopheline mosquitoes (Diptera: Culicidae)
(Oxford University Press (OUP), 1994)
The process of exflagellation was quantified for cultured Plasmodium falciparum gametocytes exposed to human sera and midgut homogenates from six vector species of Anopheles mosquitoes. Neither serum factors related to ...
Time domain terahertz impulse ranging studies
(AIP Publishing, 1995-10-02)
We present time domain impulse scattering measurements of freely propagating terahertz radiation measured with subpicosecond resolution. This fast time response corresponds to a usable bandwidth of over I THz. Measured ...
Effect of risk aversion on feeder cattle prices
(Cambridge University Press, 1994-12)
This paper determines the effects of cattle feeders' risk aversion on feeder cattle prices using pen data of Kansas feedlots. Higher profit risk results in lower feeder cattle prices. The elasticity of feeder cattle price ...
Pesticide productivity: What are the trends?
(Cambridge University Press, 1995-07)
Obtaining estimates of pesticide productivity is an economic response to the growing public concern about the steady increase of pesticide use in the United States. This type of research indicates the cost of limiting ...
Ecological and genetic analysis of copper and streptomycin resistance in Pseudomonas syringae pv. syringae
(American Society for Microbiology, 1993-04)
Strains of Pseudomonas syringae pv. syringae resistant to copper, streptomycin, or both compounds were recovered from symptomless and diseased tissue of four woody hosts in three nurseries in Oklahoma. In strains resistant ...
Immunological factor that affects Anopheles gambiae survival
(The American Mosquito Control Association, 1995)
High titers of antibodies against Anopheles gambiae midguts were produced in New Zealand rabbits to identify midgut targets for an antimosquito vaccine. The serum from one of 8 rabbits (designated R2B6) killed 71.6% (Abbott's ...
Biosynthetic gene cluster for coronamic acid, an ethylcyclopropyl amino acid, contains genes homologous to amino acid-activating enzymes and thioesterases
(American Society for Microbiology, 1994-12)
Coronamic acid (CMA), an ethylcyclopropyl amino acid derived from isoleucine, functions as an intermediate in the biosynthesis of coronatine, a chlorosis-inducing phytotoxin produced by Pseudomonas syringae pv. glycinea ...
