The amine extraction process is evaluated for pulse column
operation. A 0.1 M solution of Primene JM-T (a commercial mixture
of tertiary-alkyl primary amines) in a kerosene-base diluent is
the extractant for thorium feed in aqueous acidic sulfate solutions.
Equilibrium isotherms at room temperature are presented at
aqueous acidities of...
A translator has been designed and implemented which generates parallel code for a long instruction word parallel computer with local memories. Its main methods are to translate the sequential source code into single assignment, two-operand form, and to then assign the operations to processors so as to minimize the number...
A new method for determining ion exchange equilibrium
data by liquid scintillation counting of the equilibrated solution
phase is described. This method has been applied to determine
equilibria between Dowex 50W X8, a commercial strong cation exchange
resin, and binary and ternary solution containing the varying combinations
of H⁺¹, Cs⁺¹,...
Grazing experiments were conducted in summer, autumn and winter
to assess the effects of stock density, grazing duration, pre-grazing
pasture mass and stock type on forage intake by sheep grazing at high
stock densities for short durations. In summer and winter, sheep were
stocked at 200 sheep/ha on 0.1 ha...
We have developed crown-gall resistant transgenic plants capable of suppressing Agrobacterium tumefaciens T-DNA oncogenes. Crown gall tumors result from overproduction of auxin and cytokinin in plant cells transformed by A. tumefaciens. High phytohormone levels result from expression of two auxin biosynthetic genes, tryptophan monooxygenase (iaaM) and indole acetamide hydrolase (iaaH),...
Coral reefs have become vulnerable to climate change, with mass bleaching events, the loss of symbiotic algae (Symbiodiniaceae), increasing in both frequency and severity. As climate change continues to threaten the persistence and existence of coral reefs around the world, the biggest question posed for coral reefs is “can they...
