The German hop Hallertauer, hallertauer is highly
valued because of its "noble aroma", but it has a very low
yield when cultivated in the U.S. Two new crosses of
Hallertauer, U.S.D.A. 21455 and 21459, have high yields
and promising aroma characteristics.
In order to predict sensory properties of beers as...
The dynamics of N was studied in field grown Comice/Provence
quince BA29 pears in Medford, Oregon. Total tree biomass, N content,
and ¹⁵N evaluations suggest that young pears require little N (48 kg
N ha⁻¹ yr⁻¹). About 45% of total tree N present in dormant trees was
remobilized into new...
Kinetic properties of the two proteases, causing textural degradation of Pacific
whiting (Merluccius productus) during heating, were compared and characterized with the
synthetic substrate, Z-Phe-Arg-NMec. Pacific whiting P-I and P-II showed the highest
specificity on Z-Phe-Arg-NMec, specific substrate for cathepsin L. The K [subscript m] of
preactivated P-I and P-II...
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...
Uptake and cycling of nitrogen (N) in mature trees are not well understood.
Fertilizer-N uptake, partitioning, and use-efficiency were studied in standard strain
'Topred Delicious' and spur strain 'Redspur Delicious' mature apple trees {Malus
domestica Borck) on 'Malling 7A' (M.7A) rootstocks. The treatments consisted of a
ground application in spring,...
In recent years, the rapidly growth of CMOS technology has evolved towards submicron and deep-submicron features. Due to smaller device sizes, and significant demand for low-power designs, the maximum allowable power supply voltage is restricted. So far, two solutions; clock boosting and switched opamp schemes have been proposed. The material...
