Consider the problem of exploring a large state-space for a goal state where although many such states may exist in the state-space, finding any one state satisfying the requirements is sufficient. All the methods known until now for conducting such search in parallel using multiprocessors fail to provide consistent linear...
Seed size, abundance, viability, dormancy, and germination requirements strongly influence plant establishment and therefore are important considerations in restoration of native vegetation. These characteristics provide criteria for selection of suitable species, development of collection and pretreatment methods, and determination of seeding densities. The first set of objectives of this study...
Oxygen is often the rate-limiting factor in aerobic in situ bioremediation. This paper investigates the degree to which air or oxygen gas can be emplaced into the pore space of saturated porous media and provide a significant mass of oxygen. Column experiments were performed to test three emplacement methods: direct...
We demonstrate color shifting from the yellow to the red in the electroluminescence from (ZnGa)S:Mn films. We observe threshold voltages down to about 35 V, extremely low for such devices. We discuss the materials characteristics of the phosphor films, and the potential for improvement of the luminous intensity of the...
The impact of mesoscale eddies on the spatial distribution of zooplankton biomass was analysed using data from the Arabian Sea and the Black Sea. The highest values of spatial variance of zooplankton biomass in the upper 100 to 150 m were found in regions with maximum available potential energy of...
Excised stem segments of vines had higher specific hydraulic conductivies (flow rate per pressure gradient per stem transverse area) than did trees during the dry season in a deciduous forest in Jalisco, Mexico. Vine species averaged from 2.7 to 203 x 10-3 m2 MPa-1 s-1 and tree species from 0.8...
Blood levels of the egg yolk precursor vi-
tellogenin (VTG) can be used as a definitive marker for
the onset and progress of maturation in female teleosts.
In the present study, an enzyme-linked immunosorbent
assay (ELISA) was developed to measure VTG in blood
plasma from three species of temperate basses....
