This study explores the use of predictive mapping techniques in developing Landtype Association (LTA) maps for use in natural resource management. These maps are produced for the USDA Forest Service on a regional basis at a 1:100,000 scale. The goal of this study is to develop and test a method...
The influence of atmospheric humidity and free water on germination and germ tube growth of Botrytis cinerea Pers. ex Fr. was studied. Relative humidities (RH) were maintained inside insulated humidity chambers with sulfuric acid solutions of the appropriate concentrations. Insulation was necessary to reduce the incidence of condensation caused by...
The influence of atmospheric humidity on three aspects of sporulation of
Sphaerotheca pannosa (Wallr.) Lev. var. rosae Wor., which causes rose powdery
mildew, was studied on leaf disks of susceptible Rosa cultivar Samantha.
To study conidiophore production, leaf disks were inoculated on the adaxial
(upper) surface with conidia of S....
Studies were conducted on pathogenic specialization and
heterothallism in Sphaerotheca pannosa var. rosae, causal agent of
rose powdery mildew.
Methods were developed for isolation and identification of
Sphaerotheca pannosa var. rosae races on rose. Monoconidial isolates were initiated on detached leaves, increased on host plants,
and inoculated to rose cultivars...
The purpose of the study was to: (1) test a client-outcome
evaluation methodology in a community mental health clinic, (2)
relate a measure of clients' recent life change to client outcomes,
(3) relate functions staff perform for clients to staff mental health
profession and to client outcomes, and (4) suggest...
Predetermining the ultimate capacity of piles driven into purely
cohesive soils and purely cohesionless soils involves, respectively,
the consideration of soil shear strength in a completely undrained and
a completely drained condition. For the intermediate cases concerning
soils that possess both cohesion and internal friction (silts, clayey
silts, sandy clays,...
