Effects of temperature and growth stage on
vegetative bud development and stem hardiness of red-osier
dogwood during winter dormancy were investigated.
Results were related to a degree growth stage model and
were used to develop models to predict growth stages, to
quantify development, and to predict hardiness.
Maximum rest development...
Intensive forest management requires efficient logging techniques
to remain economical. Commercial thinnings and shorter
rotations increase piece count inversely to piece size. Continued
research aimed toward effective log handling processes is essential.
The purpose of this study was to evaluate one case of a self-loading
log truck (integral loader and...
Workers in colonies of European honey bees Apis mellifera L. clean their
nestmate's body by allogrooming behavior. This behavior may be initiated by
either grooming dancers or by the allogroomers themselves. The first occurs
less frequently (ca. 17 %) than the later (83 %). By using the inner edge of...
The geologic processes at work in American Samoa have long been a point of scientific debate. Of its numerous volcanic formations, few breach sea level, leaving an enormous proportion of their mass unavailable to traditional observation. This study aims to describe the deep sea geomorphology of American Samoa through compilation,...

Toxicological studies were carried out to evaluate the
susceptibility of codling moth, Cydia pomonella L. to
different insecticides. Bioassay procedures for adults and
larvae were standardized in terms of posttreatment holding
and temperature, age and sex of insects, insecticide
formulations and selection of a reference strain.
This study detected a...
Most of the feed required for poultry production in
the Republic of Yemen is imported from Europe. Sometimes,
feed shipments arrive later due to lack of hard currencies
to pay for the feed or to pay the freight charges. Yemeni
broiler producers in such cases feed their birds a single...
Metal-organic polyhedra (MOPs) are discrete molecules comprised of a metal and interconnecting ligands. The resulting MOP structures are porous cages, and to date, they have shown great promise toward gas capture. Ammonia is a hazardous gas that is produced in enormous quantities for use in fertilizers. In this talk, I...
Ovarian steroidogenesis is heavily controlled by the formation and function of the theca cells. A condition known as polycystic ovarian disease in humans and cystic ovarian disease in cattle is due to abnormal steroidogenesis. Knowing more about theca cell formation and function can aid in gaining further knowledge about polycystic...
Reports of previous research indicated a stimulatory effect of
triazine herbicides on growth, yield and protein content of plants and
seeds of various species.
Studies were conducted in the greenhouse, laboratory and field
to investigate the effects of atrazine (2-chloro-4-ethylamino-6-a sopropylarnino-
s-triazine) on growth, yield, seed composition, and
seed germination...
