Wheat is the major crop produced on the Anatolian Plateau of Turkey. Annual weeds cause large yields reductions in the wheat crop. Several formulations of 2, 4-D and mixtures of 2, 4-D and 2,4, 5-T are the only materials currently available for use in Turkey on wheat. The objective of...

Avian encephalomyelitis virus-infected chick embryo homogenate
was precipitated with polyethyleneglycol 6000 (PEG), extracted
with fluorocarbon, concentrated by ultrafiltration, and purified by
isopycnic gradient centrifugation. The physical and chemical properties
of the purified virus were studied. The examination of purified
avian encephalomyelitis virus (AEV) with electron microscopy using
negative stain revealed...
In recent years the types of engineering data accumulated by many telemetry systems have become so diversified and complex, and
the environment in which these systems operate has become so restricting
that telemetry systems with increased capabilities and decreased
size are becoming a necessity. Advances in integrated circuitry
techniques satisfy...
The purpose of this study was to determine the effects of the
Delphi Technique on two types of judgment; factual judgment and value
judgment. Other considerations were the effect of the process on
mean response and variability of response.
In testing the Delphi Technique this study arrived at five
definite...
Nonpoint sources of pollution are being recognized
nationwide as a significant threat to groundwater quality.
In Oregon, groundwater supplies in several areas have been
affected by contamination possibly caused by nonpoint
sources associated with agricultural activities, on-site
sewage disposal, and inadequate hazardous materials
management in urban areas. State groundwater protection...
During a study of the abnormal dienone-phenol rearrangement
discovered by Marvell and Geiszler, Imel (1960) found that 4-oxo-3,3-dimethyl-3,4-dihydrophenanthrene rearranged slowly to a phenol
which was tentatively identified as 3,4-dimethyl-l-phenanthrol;
further evidence to support this assignment was deemed essential.
The recent work by Mallory on the photochemical conversion of
stilbenes to...
