An analytical two-layer model consisting of a time-dependent stratified
boundary layer topped by stratified free flow is developed in order
to study atmospheric boundary layer production of vertical motion. To
avoid use of a constant eddy viscosity, the boundary layer equations are
layer-integrated over a fixed depth, and surface stress...
An analytical two-layer approximation of atmospheric flow is developed to study boundary-layer production of vertical motion. The model consists of a boundary layer topped by a free-flow layer. Both layers am time-dependent and possess different values of stratification. The boundary-layer equations are layer-integrated over a fixed depth and surface stress...
There is considerable variation among rose varieties in susceptibility
to mildew, and as a result of maturation, leaves of most
susceptible varieties become resistant to infection. The nature of
resistance has been sought in various studies involving environmental,
morphological, and physiological factors. An attempt was made in the
present investigation...
Previously, it has not been possible to obtain a concentrated ripe Bartlett pear essence. From studies of Bartlett pear aroma characteristics, it was found that methyl and ethyl decadienoates are the components contributing to the characteristic ripe Bartlett pear aroma. It was also found that only perfume-like aroma products, lacking...
Internal browning (IB) can be a serious problem with the use of modified atmosphere packaging
(MAP) for 'Bartlett' pears (Pyrus communis L.) grown in the Pacific Northwest during storage
and transit to distant markets. To investigate this disorder, 'Bartlett' pears harvested at
commercial maturity were packed in a commercial MAP...
The purpose of this study was to determine the phenolic
constituents of Bartlett pears and to evaluate the processed
samples for extent of discoloration and to relate the two.
Pears were obtained from three orchards in the Medford area
and from three orchards at each of the three elevations, 500,...
Recent trends towards greater fresh market use of 'Bartlett' pears has increased the need to extend its storage life to prolong the packing and marketing season in the United States Pacific Northwest region. Sixteen and 38%, respectively, of control fruit developed senescence disorders following 5 and 6 months of storage...
