The analysis of the distribution of monoterpenes through the leaf pairs of a single shoot of Mentha piperita supports Reitsema's contention that the first terpenes formed are unsaturated ketones and that saturated terpenes are produced from these. The growth of Mentha piperita under varying conditions of temperature and the leaf-by-leaf...
The major purpose of this study was to determine if there was
relationship between the power of the influence techniques used by
teacher in a nursery school setting and the response of the children
to these techniques.
The subjects were sixteen nursery school children and two
trained nursery school teachers...
Statement of the problem:
The study sought to determine whether certain
measurable differences existed between students who had
withdrawn after acceptance into the accelerated mathematics
classes in the Portland schools and students who
had persisted after acceptance into the program. Examined
were: scores on the Iowa Tests of Basic Skills,...
This study was an evaluation of fabric serviceability and consumer
acceptance of polypropylene blend knits. A review of
literature indicates a trend toward polypropylene blend fabrics for
wearing apparel, specifically for knits. The purpose of the research
was to compare two experimental double knit fabrics, a 50 percent
Creslan/Herculon blend...
Studies in other laboratories have established the presence of
the Embden-Meyerhof-Parnas (EMP) pathway and the pentose phosphate
(PP) pathway in plant tissue. Research in this laboratory with mung
bean (Phaseolus aureus) seedlings has confirmed the presence of these
two pathways as well as the glucuronic acid (GA) pathway. However,
no...
It is generally recognized that biochemical information is of
great importance to microbial taxonomy. This is particularly true
in the case of catabolic behavior of microorganisms in utilizing
glucose and allied compounds. Once the pathways operating in a
species are identified, and the relative participation of these pathways
is determined,...
The radiolysis of succinic acid in aqueous solutions induced by
gamma irradiation from ⁶⁰Co has been studied with respect to the
identification and estimation of degradation products. Detailed information
on the radiolysis of succinic acid is important in determining
what effect two carboxyl groups in the same molecule would have...
The use of radioactive isotopes as tracers in biological systems
has become widespread since the close of World War II. Proper
use of radiotracers requires a fundamental understanding of the physical
nature of radioactivity, the characteristics of ionizing radiation,
and the various methods available for measuring radioactivity.
More importantly, the...
