Past research has shown that automobile exhaust is composed
of a mixture of many different hydrocarbons and that some of these
hydrocarbons contribute more to the smog problem than others.
Natural gas has been proposed as an alternative to gasoline as a
motor fuel, and it was desired to confirm...
Pelargonium graveolens Ait., rose geranium, contains several oxygenated monoterpenes, most of which are related to each other structurally. In this work, the metabolism and interconversions of these terpenes was investigated. A chromatographic analysis of geranium oil was performed initially for the purposes of identifying the terpenes and determining which chromatographic...
The energy distribution of electrons in Townsend discharges in
helium has been experimentally investigated in a direct fashion.
A discharge is initiated between parallel plates of a small cell
mounted at the center of a spherical retarding field energy analyzer.
The anode of the cell is perforated and some electrons...
A method has been devised for the digital recording of mass
spectra and for reduction of the data by means of the CDC-3300 digital
computer. The computer program *MASSPEC was developed to reduce
the digital data obtained from a rare-gas mass spectrometer.
The author devised a method of determining peak...
Photoperiod controls the duration of both the fourth and fifth
stadia in Agalliopsis abietaria Oman. Development was arrested in
the fourth stadium unless short days were given during the second
and third instars; a short arrest of development occurred if the short
days did not begin until the fourth instar....
The western cherry fruit fly, Rhagoletis indifferens
Curran, was studied to determine the suitability of the
sterile insect technique for its control. To obtain
insect material, field collection of maggots is preferred
to sifting of soil or rearing on artificial diet.
The western cherry fruit fly is strictly univoltine;
only...
We have investigated the gaseous structure of cyclohexane-
1,4-dione via electron diffraction. The large amplitude
motion, as suggested from spectroscopic, dipole moment
and earlier electron diffraction data was studied. The
structure was refined in two types of models: a single
"distorted boat" conformer, and a model comprised of a
superposition...
Chronic overcapacity has been identified as a major cause of the overfishing of Europe’s fish stocks and
the poor economic performance of the European fishing fleets. Mechanisms are needed to ensure that the
capacity of European fishing fleets remain proportionate to available fish stocks. To that end, the
European Commission...
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...
The purpose this study was to determine how group counseling
influenced attitudes of low-income youth toward self, others,
and society. The subjects, all high school age, were participants
in an education program held on a college campus during the 1970
regular collegiate summer session. They lived in a residence hall...
