The Isolated Individual in the Novels of Carson McCullers

The Isolated Individual in the Novels of Carson McCullers

Date: August 1965
Creator: Smith, Kyle A.
Description: The theme of isolation in some degree is drawn through every character in every novel by Carson McCullers. This thesis examines the works of McCullers and the ideas of loneliness and isolation in her works and in her life.

Isolation and analysis of cotton genomic clones encompassing a fatty acid desaturase (FAD2) gene

Isolation and analysis of cotton genomic clones encompassing a fatty acid desaturase (FAD2) gene

Date: May 2001
Creator: Kongcharoensuntorn, Wisatre
Description: Polyunsaturated fatty acids are major structural components of plant chloroplast and endoplasmic reticulum membranes. Two fatty acid desaturases (designated FAD2 and FAD3) desaturate 75% of the fatty acids in the endoplasmic reticulum. The w -6 fatty acid desaturase (FAD2) may be responsible for cold acclimation response, since polyunsaturated phospholipids are important in helping maintain plant viability at lowered temperatures. To study regulation of FAD2 gene expression in cotton, a FAD2 gene was isolated from two genomic libraries using an Arabidopsis FAD2 hybridization probe and a cotton FAD2 5¢ -flanking region gene-specific probe, respectively. A cotton FAD2 gene was found to be in two overlapping genomic clones by physical mapping and DNA sequencing. The cloned DNA fragments are identical in size to cotton FAD2 genomic DNA fragments shown by genomic blot hybridization. The cotton FAD2 coding region has 1,155 bp with no introns and would encode a putative polypeptide of 384 amino acids. The cotton FAD2 enzyme has a high identity of 75% with other plant FAD2 enzymes. The enzyme has three histidine-rich motifs that are conserved in all plant membrane desaturases. These histidine boxes may be the iron-binding domains for reduction of oxygen during desaturation. To confirm that this FAD2 ...

Isolation and Caritas: Polar Themes in Melville's The Confidence-Man

Isolation and Caritas: Polar Themes in Melville's The Confidence-Man

Date: December 1971
Creator: Hollen, Norman V.
Description: The thesis examines isolation and caritas, or charity, in The Confidence-Man as polar themes which express, respectively, withdrawal from and suspicion of the human community and integration within and appreciation for that community. Isolation is considered a negative theme; caritas, an affirmative theme.

Isolation and Characterization of Polymorphic Loci from the Caribbean Flamingo (Phoenicopterus ruber ruber): New Tools for Wildlife Management

Isolation and Characterization of Polymorphic Loci from the Caribbean Flamingo (Phoenicopterus ruber ruber): New Tools for Wildlife Management

Access: Use of this item is restricted to the UNT Community.
Date: December 2005
Creator: Preston, E. Lynn
Description: Methods to determine genetic diversity and relatedness within populations are essential tools for proper wildlife management. Today the approach of choice is polymerase chain reaction-based microsatellite analysis. Seven new polymorphic loci were isolated from a microsatellite-enriched Caribbean flamingo genomic library and used to characterize survey populations of Caribbean and African greater flamingos. In addition, four of these loci were used to verify parentage relationships within a captive-breeding population of African greater flamingos. Parentage predictions based upon gamekeeper observations of breeding and nesting did not always agree with genetic-based parentage analyses of the nine suggested family groups. Four family groups were supported (groups I, II, III and VI) by there results. However, an analysis of the remaining five suggested groups, with a total of eight offspring/dam and eight offspring/sire suggested relationships, yielded seven exclusions of the suggested dam and six exclusions of the suggested sire. This put the overall suggested dam exclusion rate at 35% and exclusion rate for suggested sires at 29%. Although the keeper observation data for our family groups must be considered a variable of concern at this time, these findings are certainly suggestive that more carefully controlled studies may reveal that flamingos are not monogamous as long ...

Isolation and Characterization of the Operon Containing Aspartate Transcarbamoylase and Dihydroorotase from Pseudomonas aeruginosa

Isolation and Characterization of the Operon Containing Aspartate Transcarbamoylase and Dihydroorotase from Pseudomonas aeruginosa

Date: May 1993
Creator: Vickrey, John F. (John Fredrick), 1959-
Description: The Pseudomonas aeruginosa ATCase was cloned and sequenced to determine the correct size, subunit composition and architecture of this pivotal enzyme in pyrimidine biosynthesis. During the course of this work, it was determined that the ATCase of Pseudomonas was not 360,000 Da but rather present in a complex of 484,000 Da consisting of two different polypeptides (36,000 Da and 44,000 Da) with an architecture similar to that of E. coli ATCase, 2(C3):3(r2). However, there was no regulatory polypeptide found in the Pseudomonas ATCase.

Isolation and Identification of an Odor Compound Produced by a Selected Aquatic Actinomycete

Isolation and Identification of an Odor Compound Produced by a Selected Aquatic Actinomycete

Date: August 1968
Creator: Henley, Don E.
Description: The purpose of this study was to develop an efficient method for the concentration of specific volatile taste and odor compounds produced by a selected aquatic actinomycete. A second purpose was to isolate and identify the specific taste and odor compound present in the highest concentration.

Isolation and Partial Characterization of a Bacterium Which Gives Off Filtrable Cells

Isolation and Partial Characterization of a Bacterium Which Gives Off Filtrable Cells

Date: May 1973
Creator: Siu, Henry H. W.
Description: The present study was on the isolation of a bacterium capable of producing filtrable forms which passed through the 0.45µ filter membrane and regenerated the parental form; the testing of the true filtrability of the isolate; the relationship between growth of the isolate and appearance of filtrability; partial characterization of the isolate and visualization of the elements that passed through the membrane filter with electron microscopy and shadow casting technique.
