The Bureau of Entomology has been conducting systematic and economic
investigations of the weevils infesting the bark of the trunk and
terminal shoots of conifers in the United States, the results of which will be
published in the regular technical and popular bulletins ; but since these can not be...
Urbanites who own forest land belong to a larger category of owners often referred to as small woodland owners. As a group, small woodland owners have been the subject of much investigation. Little research, however, has focused specifically on urban-dwelling owners who, as defined by the Census Bureau, live in...
This edition contains research updates and a comprehensive list of publications summarizing research conducted by faculty of the Oregon Wine Research Institute at Oregon State University. Dr. Bob Martin, Research Plant Pathologist (Virology), USDA, opens the newsletter with a research update on grapevine red blotch disease that provides growers with...
Addition of the methylcarbamate compounds p-chlorophenyl
N-methylcarbamate (PPG-124) and 1-naphthyl N-methylcarbamate
(carbaryl) to various herbicides has resulted in reduced rates of
degradation. Carbaryl affects the degradation of certain herbicides
in both plants and soils while PPG-124 has only been demonstrated
to affect degradation in soils. Both these materials are effective...
A summary of moored instrument measurements over the continental
shelf of Peru is presented. Measurements of variables were made in an
upwelling zone between Pisco and San Juan, from 28 March to 9 April, 1969.
Time series of temperature and horizontal current and wind velocities were
obtained at several depths...
We measure the thermal conductivities of nano-grained strontium titanate (ng-SrTiO₃) films deposited on sapphire substrates via time-domain thermoreflectance. The 170 nm thick oxide films of varying grain-size were prepared from a chemical solution deposition process. We find that the thermal conductivity of ng-SrTiO₃ decreases with decreasing average grain size and attribute...
