Refining Ornamental Heat Zone Categories with Evapotranspiration

Turfgrass and Ornamental Plant Evapotranspiration and Crop Coefficient Literature Review

pH-zone-refining countercurrent chromatography.

A recently developed preparative technique, pH-zone-refining countercurrent chromatography (CCC), separates organic acids and bases according to their pKa and hydrophobicity. The hydrodynamic mechanism of pH-zone-refining CCC is illustrated in two elution modes along with a simple mathematical analysis. Separations include acidic and basic derivatives of amino acids and peptides, hydroxyxanthen...

Refining Syntactic Categories Using Local Contexts

As an extension of decades of syntactic theorizing, treebanks have inherited a small set of phrasal categories, which abstract over the environments that the categories can occur in. Extending ideas from Johnson (1998), we explore encoding information from the local tree context in each category. We then discuss two clustering techniques which preserve the distributionally relevant category dis...

Urban climates and heat islands: albedo, evapotranspiration, and anthropogenic heat

As an introduction to this special issue on urban heat islands and cool communities, this paper reviews some of the characteristics of urban climates and the causes and effects of urban heat islands. In particular, the impacts of surface albedo, evapotranspiration, and anthropogenic heating on the near-surface climate are discussed. Numerical simulations and field measurements indicate that inc...

Variability in riparian zone potential and actual evapotranspiration

Micrometeorological and hydrological measurements were made over one growing season using automatic weather stations and weighing lysimeters at several locations within a multiple land-use agricultural catchment in Southern Ontario. This paper compares modelled potential evapotranspiration (PET) and measured actual evapotranspi-5 ration (AET) values obtained from the soil weighing lysimeters, a...
