The medicinal flora of native North America: An analysis
(Elsevier, 1991-01)
This paper describes an analysis of the plants of North America which have been used medicinally by Native North Americans. A method using regression residuals is developed for analyzing large quantities of data, divided ...
African bees in the Americas: Insights from biogeography and genetics
(Elsevier, 1991-01)
The spread of African honey bees in South and Central America is one of the most remarkable and certainly among the most highly publicized instances of biological invasion. Their aggressive nest defense has led to numerous ...
Interaction of fatty acids with recombinant rat intestinal and liver fatty acid-binding proteins
(Elsevier, 1991-04)
Intestinal enterocytes contain two homologous fatty acid-binding proteins, intestinal fatty acid-binding protein (I-FABP)2 and liver fatty acid-binding protein (L-FABP). Since the functional basis for this multiplicity is ...
Modeling of immunosensors under nonequilibrium conditions : I. Mathematic modeling of performance characteristics
(Elsevier, 1991-08-01)
Immunosensors for the detection of small analytes that use analyte-enzyme conjugates as signal generators require special attention if operated under nonequilibrium conditions. If the size of the analyte and the analyte-enzyme ...
The rate and locus of development of rat vallate taste buds
(Elsevier, 1991-02-22)
Several hundred taste buds develop and mature in the trench walls of the rat's vallate papilla during the first 3 months after birth. The objective of this investigation of taste bud development was to determine: (i) whether ...
Rapid computation of the radiative absorption rate in the v3 mode of mesospheric and lower thermospheric ozone
(Elsevier, 1991-11)
We have developed an algorithm to calculate rapidly and accurately the rate (photons-molecule-1-sec-1) at which the ozone v3 fundamental band absorbs i.r. radiation in the terrestrial upper mesosphere and lower thermosphere. ...
Control of Enterococcus faecalis sex pheromone cAD1 elaboration: Effects of culture aeration and pAD1 plasmid-encoded determinants
(Elsevier, 1991-05)
Aeration of plasmid-free Enterococcus faecalis strains resulted in an 8- to 16-fold decrease in sex pheromone cAD1 activity in culture filtrates. Levels of two unrelated pheromones, cPD1 and cAM373, were unaffected by ...
Structural and kinetic studies in propene oxidation over Sb oxide dispersed on TiO2
(Elsevier, 1991-02)
Antimony oxide dispersed on TiO2 was characterized using FTIR, Raman, and Auger spectroscopies as well as XRD. They indicate that the electronic environment about Sb is perturbed at low concentration suggesting that the ...
