Evaluation of time-average dispersion models for estimating pheromone concentration in a deciduous forest
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1984-07)
The Sutton and more recent Gaussian plume models of atmospheric dispersion were used to estimate downwind concentrations of pheromone in a deciduous forest. Wind measurements from two bivane anemometers were recorded every ...
Rapid protein release from Escherichia coli by chemical permeabilization under fermentation conditions
(Wiley Subscription Services, Inc., A Wiley Company, 1992-03-25)
Overall protein release greater than 75% in less than 1 h can be attained by exposing exponentially growing Escherichia coli cells to 0.4 M guanidine plus 0.5% Triton X-100 at 37°C in medium. Cell growth stops immediately ...
Chronic haloperidol treatment increased calcium-dependent phosphorylation in rat striatum
(Elsevier, 1982-01-04)
In previous studies, we observed that when rats were chronically treated with haloperidol, there was a significant increase of calmodulin activity in their striatal membranes. Calmodulin is knwon to modulate calcium-dependent ...
Homologs of genes and anonymous loci on human Chromosome 13 map to mouse Chromosomes 8 and 14
(Springer-Verlag, 1995-04)
To enhance the comparative map for human Chromosome (Chr) 13, we identified clones for human genes and anonymous loci that cross-hybridized with their mouse homologs and then used linkage crosses for mapping. Of the clones ...
Postnatal ontogeny of acetylated and non-acetylated B-endorphin in rat pituitary
(Elsevier, 1983)
Extracts of the anterior lobe and intermediate lobe of postnatal (P) (Day P1, P7, P14, P21, P28, P35, P42) and adult male Spraque-Dawley rats were analyzed by both a Beta-endorphin (B-END) radioimmunoassay and a radioimmunoassay ...

Individual and population sex allocation patterns
(Elsevier, 1987-02)
A variety of sex allocation models is considered in which (i) the reproductive returns on investment in males differ from the returns on investment in females, (ii) the amounts of resources available for reproduction vary ...
There is no support for Jensen's hypothesis of nemerteans as ancestors to the vertebrates
(Kluwer Academic Publishers; Springer Science+Business Media, 1997-01)
Nemerteans (phylum Nemertea) have been viewed by mostzoologists as descended from, or closely related to,the flatworms. This view is based mainly on theirsupposedly acoelomate body. Their ancestry, however,is a point of ...
Identification and characterization of a human transthyretin variant
(Elsevier, 1987-10-14)
An apparent Mr variant of plasma transthyretin (TTR), previously detected using 2-D PAGE, is the first reported occurrence of this type of human TTR variant. We characterized the variant TTR to determine the nature of this ...
Substituent effects on the oxidation of substituted biphenyl congeners by type II methanotroph strain CSC1
(Springer-Verlag, 2005-05)
The oxidation potential of type II groundwater methanotroph, strain CSC1, expressing soluble methane monooxygenase, was measured in the presence of 10 ortho -substituted biphenyls with varying electronics, sterics, and ...
