Pyrolysis of 4-cycloheptene-l-methyl acetate under flow conditions at 285° gives only rearranged bicyclic acetates and hydrocarbons rather than the anticipated simple elimination product methylenecyclohept- 4-ene. These rearranged acetates have the same structures and are formed in virtually the same relative percentages as those observed in the "π- route" solvolysis of...
This study was designed to identify those specific mathematics
computational and application skills, and combinations of mathematics
skills, which have a positive relationship to success in introductory
chemistry for community college students.
Additional areas of interest investigated, but secondary to the
main study, were the relationships between mathematical growth
shown...
Columbia River sediment was irradiated with ultraviolet light to
determine if organic material could be removed without altering the
sorptive properties of the hydrous oxides of iron and manganese.
A laboratory preparation of Zn-65 spiked hydrous ferric oxide
was subjected to ultraviolet irradiation in order to assess the photochemical
effect...
Fertilizer studies at the Oregon State University Vegetable
Research Farm were conducted for two years to evaluate the effect
of different nutrient sources on yield and selected quality components.
Sources of nutrients included sewage sludge, fresh and dried poultry
manure, a soybean residue from oil extraction, and several mineral
fertilizers....
An inexpensive method for calibrating an infrared analyzer to measure varying ranges of carbon dioxide partial pressures (Pco₂) is described. A discussion is made of the hydrographic (temperature, salinity, and sigma-t) and chemical (dissolved oxygen, AOU, Pco₂ pH, and nutrients) variables that were observed along the Newport hydrographic line in...
