The external and internal morphology are considered and important morphological characters are found which relate Macrovelis to the family Mesoveliidae. Both macropterous and Brachypterous forms occur throughout the western half of the United States. The adults and nymphs are restricted to the margins of springs and streams during the reproductive...
This investigation was designed to determine the extent to which
students who are completing planned curricula in mathematics education
are proficient in spatial visualization abilities and possess mathematical
understandings. The effects of mathematics curricula upon
the development of these abilities and understandings and the relationships
between these abilities and understandings...
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...
