The freshwater snail Biomphalaria glabrata serves as the intermediate host of the
blood fluke Schistosoma mansoni. Previous studies using the 13-16-R1 strain of B.
glabrata demonstrated an association between the gene encoding Cu/Zn superoxide
dismutase (SOD1) and susceptibility/resistance to the parasite. This association is
assumed to involve a polymorphism that...
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 aim of this dissertation is to develop non-traditional approaches to alternating-current thin-film electroluminescent (ACTFEL) device fabrication. ACTFEL technology suffers from a lack of adequately bright and efficient primary-color phosphors and cannot presently compete in the low-cost display market. Therefore the research presented in this dissertation focuses on an exploration...
Purpose:
The purpose of this study was to identify the major contributive
factors affecting enrollment trends in secondary level agricultural
programs in Oregon and California, as perceived by Oregon and
California agricultural instructors and their respective principals.
Methods and Procedures:
A review of the literature revealed three areas that were...
Clinical supervision serves a key component in ensuring practitioners' competency and professional identity. This practice also allows more skilled clinicians to serve as gatekeepers to the field, which helps protect clients and the profession. As the use of the Internet increases, many clinical services, including supervision, are more common in...
The achievements of this thesis are the development of several models for the SPICE (Simulation Program with Integrated Circuit Emphasis) simulation of alternating-current thin-film electroluminescent (ACTFEL) devices, organic light-emitting devices (OLEDs), and polymer light-emitting devices (PLEDs). First, an ACTFEL model based on the built-in HSPICE Fowler-Nordheim tunneling diode is developed,...
A computationally efficient algorithm has been developed for
determining exact or approximate solutions for large scale generalized
fixed charge problems. This algorithm is based on a relaxation
of the Benders decomposition procedure, combined with a linear
mixed integer programming (MIP) algorithm specifically designed to
solve the problem associated with Benders...
p-type conducting films of α- BaCu₂S₂ have been deposited onto glass and KBr substrates, yielding a conductivity of 17 S/cm and a Hall mobility of 3.5 cm²/Vs. For a 430-nm-thick film, the optical transparency approaches 90% in the visible portion of the spectrum at 650 nm, and a transparency of...
