Sensitivity of climate forcing and response to dust optical properties in an idealized model

Creator:: Shell, Karen M. and Somerville, Richard C. J.
Abstract:: An idealized global climate model is used to explore the response of the climate to a wide range of dust radiative properties and dust layer heights. The top-of-the-atmosphere (TOA) shortwave forcing becomes more negative as the broadband shortwave single scattering albedo increases and the broadband shortwave asymmetry parameter decreases, but...

Direct radiative effect of mineral dust and volcanic aerosols in a simple aerosol climate model

Creator:: Shell, Karen M. and Somerville, Richard C. J.
Abstract:: Airborne mineral dust can influence the climate by altering the radiative properties of the atmosphere, but the magnitude of the effect is uncertain. An idealized global model is developed to study the dust-climate system. The model determines the dust longwave and shortwave direct radiative forcing, as well as the resulting...

Atmospheric response to solar radiation absorbed by phytoplankton

Creator:: Shell, K. M., Frouin, R., Nakamoto, S., and Somerville, R. C. J.
Abstract:: Phytoplankton alter the absorption of solar radiation, affecting upper ocean temperature and circulation. These changes, in turn, influence the atmosphere through modification of the sea surface temperature (SST). To investigate the effects of the present-day phytoplankton concentration on the atmosphere, an atmospheric general circulation model was forced by SST changes...

Influence of ascorbic acid supplementation on copper status in young adult men

Creator:: Finley, Elizabeth Bidwell
Abstract:: Thirteen healthy adult males, ages 20-40, consuming self selected diets, were given instructions to take one 500 mg tablet of ascorbic acid three times a day with their meals for a period of ten weeks. The effect of this daily supplementation on copper status was investigated. An estimation made from...

The effect of erythorbic acid on the determination of ascorbic acid levels in selected foods by high performance liquid chromatography and spectrophotometry

Creator:: Tuan, Shenhsiu
Abstract:: A high performance liquid chromatography (HPLC) procedure using a LiChrosorb-NH₂ column and a eluant buffer of 75:25 (v/v) of acetonitrile:0.05 M KH₂P0₄, pH 5.95, was developed for the successful separation and determination of ascorbic and erythorbic acids in selected food samples. Application of the method, which is sensitive, rapid and...

The Bob Marshall Wilderness Area of Montana ; a study in land use

Creator:: Merriam, Lawrence C.
Abstract:: A wilderness area, as administered by the U. S. Forest Service, is a tract of undeveloped land over 100,000 acres in size with no roads or provision for motorized transportation. Commercial timber cutting, hotels, stores, and similar developments are prohibited. While there are some exceptions for private holdings and administrative...

The stability of ascorbic acid in bottled cranberry-based beverages under home-use conditions

Creator:: Wong, Geoffrey K.
Abstract:: Commercially bottled, vitamin C-fortified, cranberry juice cocktail and cranberry-apple (cranapple) juice drinks were stored at 5°C under simulated home-use conditions. Ascorbic acid (AA) and dehydroascorbic acid (DHA) levels were evaluated over a period of seven days by high performance liquid chromatography (HPLC). Total vitamin C content was also determined by...
