The relationship between the macro- and microclimate
(Elsevier, 1965-04)
A search of the literature has yielded a very small number of papers dealing with quantitative relationships between the macro- and microclimate. Such relationships would be of great value in view of the difficulty in ...
Protein kinase C and clostridial neurotoxins affect discrete and related steps in the secretory pathway
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1993-12)
1. The effects on catecholamine secretion of activation of protein kinase C and clostridial neurotoxins were examined in digitonin-permeabilized bovine adrenal chromaffin cells.
Technical knowledge and water resources management: A comparative study of river basin councils, Brazil

Resolution in the receptor binding of putative [mu] and [kappa] opiates
(Elsevier, 1984-05-28)
Conditions for the stereospecific binding of 3H-ethylketocyclazocine and 3H-etorphine were established in membranes from rat and pigeon brain. In displacing the specific binding of the radiolabeled ligands, putative [mu] ...
Selection of rare event cells expressing [beta]-galactosidase
(Elsevier, 1991-06)
The ACAS Interactive Laser Cytometer was used to screen and select mammalian cells in culture infected with a retrovirus construct containing the Escherichia coli lacZ and neomycin resistance genes. The product of expression ...
Synthesis and maturation of phage P22 DNA : II. Properties of temperature-sensitive phage mutants defective in DNA metabolism
(Elsevier, 1968-06-28)
Three temperature-sensitive mutants of phage P22 have been isolated which are defective in phage DNA metabolism. After infection at restrictive temperature, one mutant (ts 12.1) fails to synthesize measurable quantities ...
Sequence of the fourth and fifth Photosystem II Type I chlorophyll a/b -binding protein genes of Arabidopsis thaliana and evidence for the presence of a full complement of the extended CAB gene family
(Kluwer Academic Publishers; Springer Science+Business Media, 1992-08)
A second locus ( Lhb1B ) encoding Photosystem II Type I chlorophyll a/b -binding (CAB) polypeptides was identified in Arabidopsis thaliana . This locus carries two genes in an inverted orientation. The predicted sequences ...
Evolutionary consequences of eating: Trichosurus vulpecula (marsupialia) and the genus Eucalyptus
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1975-12)
While being somewhat specialized on a diet of mature Eucalyptus leaves (66% of feeding time), wild Trichosurus vulpecula consume an average of three different foods per night. Usually, these foods are two different species ...
