Beer is one of the most extensively consumed beverages world-wide and it is almost always brewed with hops (Humulus lupulus, L.). Hops provide beer with bitterness, aroma, flavor and texture and also enhance specific beer properties such as foam stability, clarity (colloidal stability), color, flavor stability and microbial stability. Hops...
Representing the most common flavonoid consumed in the American diet, the flavanols and their polymeric condensation products, the proanthocyanidins, are regarded as functional ingredients in various beverages, whole and processed foods, herbal remedies and supplements. Their presence in food affects food quality parameters including astringency, bitterness, sourness, sweetness, salivary viscosity,...
Several empirical formulas that may be used to estimate available
chilling are presented in this study. Many climatic parameters
were considered in the derivation of these formulas. One equation
employing only maximum and minimum temperatures had a coefficients
of correlation (R) and R² values of .978 and .957, respectively. This...
Post World War II victory culture and its fallout-the consensus ideology-led to the creation of a middle class willing to conform to a prescribed set of ideals, safely removed from all danger, and enjoying the material benefits of a growing middle-class income bracket. Walt Disney and Hugh Hefner, two seemingly...
Oogenesis in the sea urchin Strongylocentrotus purpuratus was
studied at the fine structural level, with special emphasis on the relationship
between the two main cell types within the ovary: the egg cells
and the nutritive phagocytes, or accessory cells. The nutritive
phagocytes are flagellated cells with extensive pseudopods which store...
Purposeful introductions of exotic species for rehabilitation efforts following wildfire are common on rangelands in the western U.S., though potential ecological impacts of introduced species in novel environments are often poorly understood. One such introduced species, Kochia prostrata (L.) Schrad (forage kochia) has been seeded on over 200,000 ha throughout...
Ultrastructural analysis and chemical inhibition studies were
carried out on first cleavage of Mytilus zygotes to determine possible
relationships between the mitotic apparatus and the cortex during
polar lobe formation.
The stages of mitosis correlated with the appearance of the
polar lobe were first determined by light microscopy. The polar...
Surveys of both patients and health care providers have indicated strong interest, up to 95%, in favor of advance directives, which are legal documents that express patients' healthcare treatment decisions. Despite the widespread support for advance directives, actual completion rates are very low, ranging from 4% to 20% for the...
Mule deer (Odocoileus hemionus hemionus) and Rocky Mountain elk (Cervus canadensis nelsoni; hereafter elk) populations in northeast Oregon have declined in the past 10 to 20 years. Concurrent with these declines, cougar (Puma concolor) populations have apparently increased, leading to speculation that predation by cougars may be responsible for declining...
