The influence of potassium on the removal of 137Cs by live Chlorella from low level radioactive wastes
(Elsevier, 1974-04)
The objective of this study was to determine the concentration of stable potassium that must be present in a radioactive waste solution to maximize the uptake of radiocesium by algae without a substantial reduction in algal ...
The taxonomic status of the genera Superlestes and Cyptolestes Williamson, 1921 (Odonata: Lestidae)
(University of Michigan Museum of Zoology, 1980)
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 ...

Multidimensional analysis of diatom morphologic and morphometric phenotypic variation and relation to niche
(1995)
There have been few past studies of relationships between phenotypic variation and population niche. In this study phenotypic variation was separated in to morphometric and morphologic variation which was related to niche ...
