The study was conducted to evaluate the use and perceived effectiveness of occupational safety and health consultative services among Oregon corporations. The three types of consultative services examined: workers' compensation insurance; private; and Oregon Occupational Safety and Health. The research examined if corporations, categorized by corporation size, within the four...
The temperature-dependent development of pupae and adults of strawberry root weevil (SRW) Otiorhynchus ovatus (L.) was studied in strawberry (Fragaria x ananassa Duch. var. 'Totem'). The development of pupae and adults was investigated at constant temperatures from 3-33°C at 3°C intervals. Major emphasis was on the development of a weighted...
Dinosaurs represent one of the most successful evolutionary radiations of terrestrial vertebrates, with a myriad of forms that dominated the terrestrial environment for over 180 million years. Despite the fact that dinosaurs are the focus of extensive popular and scholarly investigation, relatively little is actually known of their biology. The...
Mixed models have been widely used to model data from experiments which have fixed and random
factors. Often there is interest in the estimation of fixed effects and variance components. The likelihood
procedure is a general technique that has been applied to such problems. This procedure can be
computationally difficult,...
Proteolytic degradation of fish flesh occurring at elevated temperatures is the
primary limitation for the commercial utilization of arrowtooth flounder (ATF).
Characterization of the autolytic activity of ATF muscle incubated at various pHs
and temperatures indicated the involvement of heat-activated proteinases active at
acidic and alkaline pHs. Further characterization of...
Many phytoplankton and macroalgae release dissolved organic carbon (DOC). Many macroalgae also produce and store secondary metabolites which in some case have been shown to deter their grazers. The metabolites may be released into the surrounding seawater and could inhibit primary production. On the other hand, some phytoplankton can use...
