Carotenoid pigments in W. dermatitidis, the first pathogenic, dematiaceous fungus in which carotenoid pigments nave been reported, are located primarily (81%) in lipid organelles which floated on the surface of the supernatant fraction of lysed cells. Pigment in this fraction could be extracted with ethyl ether without prior treatment with acetone indicating the pigment is unbound in the lipid organelle. Eight percent remains after exhaustive ether extraction and is recovered after the sample is treated with acetone indicating this fraction is non-covalently bound to proteins in the membranes associated with the lipid organelle. The remaining pigment (about 12%) represents contamination of the supernatant with the lipid organelles.

The purpose of the present study was to determine: (1) that dental office personnel would be exposed to more toxic chemicals in the workplace than the non-dental office controls; (2) that exposure should lead to a reduction in the efficiency of the immune system in the individuals in the dental office; and (3) the immunological deficit should manifest itself in psychological and/or physiological pathology as measured on the Profile of Mood States (POMS) and Bender Gestalt.

The R. Jan LeCroy Center for Educational Telecommunications of the Dallas County Community College District is a leading producer of telecourses for credit at the college level. In addition, the center is becoming involved with other kinds of electronic communication for educational purposes, including the Community College Satellite Network (CCSN), the State of Texas Academic Resources Link (STARLINK), and Instructional Television Fixed Service (ITFS). This study chronicles the DCCCD's progress in electronic distance learning from the time of its first telecourse in 1972 to the present time. This study also describes the center's purposes, the reasons for its growth, the problems that have been encountered, the people who provided its leadership, and the telecourses that have been offered and produced by the DCCCD.

The Marital Interaction Dimension Inventory (MIDI) is an assessment that evaluates marital relationships on seven dimensions; sexuality, self disclosure, emotional affiliation, conflict resolution, power outcome, commitment, and identity. The MIDI provides scores on and individual's actual and desired relationship.

In this study a library of EcoRI fragments encompassing the entire TOL region of the Pseudomonas putida TOL plasmid pDK1 was constructed in the Escheria coli cloning vector pBR325.

This dissertation traces imperialist ideology as it functions in the texts of two radical Liberal critics of imperialism, Leonard Woolf and E. M. Forster. In chapters two and three respectively, I read Woolf's autobiographical account Growing and his novel The Village in the Jungle to examine connections between "nonfictional" and "fictional" writing on colonialism. The autobiography's fictive texture compromises its claims to facticity and throws into relief the problematic nature of notions of truth and fact in colonialist epistemology and discursive systems.
