A laboratory course in experimental genetics for the biology major.

A laboratory course in experimental genetics for the biology major.

Access: Use of this item is restricted to the UNT Community.
Date: December 2001
Creator: Lux, Melissa McNeil
Description: This manual has been designed for a class of twenty- four students concurrently enrolled in the lecture course. The laboratory aids in the learning process and fosters an interest in the science of genetics. This manual and the experiments contained within are both informative and fun. The manual correlates with and expands upon the genetics course. Each investigation, with the exception of the Drosophila melanogaster project, can be completed in a 3-4 hour timeframe. This manual provides a “hands on” experience of theories simply discussed in the lecture course. This manual is intended to be a one-source manual where each investigation is designed to include an adequate introduction. Special attention has been given for each investigation with both the student and instructor in mind.

A Laboratory Study of the Asiatic Clam (Corbicula fluminea Müller) as Influenced by Substrate, Food Source and Water Type

A Laboratory Study of the Asiatic Clam (Corbicula fluminea Müller) as Influenced by Substrate, Food Source and Water Type

Date: May 1995
Creator: Halbrook, Courtney (Courtney Ann)
Description: Growth of Corbicula fluminea was monitored in the laboratory. Three experiments were conducted. Experiment I utilized three substrates and one food type. Experiment II utilized three substrates and two food types. Experiments I and II were conducted to determine if substrate type or food type effected growth. Experiment III used no substrates, one food type and was conducted to determine growth response to different types of water. Clams were maintained in three substrates: sand, gravel and clay. Clams were also maintained without substrate. Growth was monitored by measuring shell length (mm) and recording the weight (mg) of clams over a period of thirty days. At the end of the test period data were evaluated for normality and homogeneity.

Labor's Attitude toward Administered Prices

Labor's Attitude toward Administered Prices

Date: 1955
Creator: Lowry, William L.
Description: What effect does controlled price have upon the profits of business or of industrial concerns, upon the wages paid to workers, upon the public demand for articles whose price is controlled, upon the volume of production, and upon the public attitude toward those businesses whose products are protected by controlled prices? What are the attitudes of organized labor toward the principle of administered or controlled prices? What are the reasons advanced by both management and labor for and against controlled prices? What is the over-all or long-term influence of controlled prices upon the total economic progress of the nation? These are some of the questions which will be considered in this study.

Lack of Evaluation as Evaluation: Analysis of an African American Woman’s Narrative

Lack of Evaluation as Evaluation: Analysis of an African American Woman’s Narrative

Date: August 2011
Creator: van Drunen, Vanessa
Description: This thesis examines an African American woman’s narrative about the day that her daughter was shot. Like many personal narratives of “frightening experiences,” the speaker in this narrative highlights the peak of her story, making sure her point is salient. In earlier analyses, it has been shown that evaluation tends to cluster around the peak of the narrative. In “The day my daughter got shot” we see that this event-filled narrative is not evaluated as predicted as there is no increased usage of evaluative devices at one single point in the narrative. Instead, it is a change in patterning of a number of linguistic and paralinguistic devices that conspire to bring special attention to the peak of the narrative. By examining multiple devices at once, it is seen that they create a cumulative effect that makes the story interesting and exciting, resulting in a successful narrative.

Lactate Dehydrogenase of Hymenolepis Diminuta: Isolation and Characterization

Lactate Dehydrogenase of Hymenolepis Diminuta: Isolation and Characterization

Date: December 1971
Creator: Burke, William F.
Description: Lactate dehydrogenase was isolated in pure form from crude extract of the cestode Hymenoleois diminuta by heat treatment and column chromatography. The purified enzyme has a specific activity of 106 units per mg protein. The molecular weight of the purified protein was 75,000 as determined by Sephadex gel filtration and analytical ultracentrifugation. An equilibrium ultracentrifugation study suggests a subunit molecular weight of 39,000. From these data, a dimer form of the native enzyme is proposed.

Lamb's Self-Revelations as "Elia"

Lamb's Self-Revelations as "Elia"

Date: January 1968
Creator: Rushing, Paula B.
Description: The purpose of this thesis is to determine the nature of Charles Lamb as revealed in his Elia essays. To this end, these essays form the major portion of the text. The general procedure for ascertaining what these excerpts indicate is as follows: first, the characteristics of Charles Lamb are determined from a study of the Elia essays; second, these characteristics are considered in relation to information derived from biographies. Careful attention is given to significant discrepancies between the essays and other sources.

Laminar Natural Convection From Isothermal Vertical Cylinders

Laminar Natural Convection From Isothermal Vertical Cylinders

Date: August 2012
Creator: Day, Jerod
Description: Laminar natural convection heat transfer from the vertical surface of a cylinder is a classical subject, which has been studied extensively. Furthermore, this subject has generated some recent interest in the literature. In the present investigation, numerical experiments were performed to determine average Nusselt numbers for isothermal vertical cylinders (103 < RaL < 109, 0.5 < L/D <10, and Pr = 0.7) with and without an adiabatic top in a quiescent ambient environment which will allow for plume growth. Results were compared with commonly used correlations and new average Nusselt number correlations are presented. Furthermore, the limit for which the heat transfer results for a vertical flat plate may be used as an approximation for the heat transfer from a vertical cylinder was investigated.

Landscape Ecological Characteristics of Habitat of the Red-cockaded Woodpecker

Landscape Ecological Characteristics of Habitat of the Red-cockaded Woodpecker

Date: December 1993
Creator: Thomlinson, John Richard
Description: Geographic information systems (GIS) technology was used to analyze factors influencing habitat use by an endangered species, the red-cockaded woodpecker. The study area was the western part of the Raven Ranger District of the Sam Houston National Forest, Texas. The factors considered included both structural characteristics and spatial relationships among stands of trees in the habitat.

Landscape forest modeling of the Luquillo Experimental Forest, Puerto Rico.

Landscape forest modeling of the Luquillo Experimental Forest, Puerto Rico.

Date: December 2002
Creator: Abbott-Wood, Chris
Description: This thesis contributes to modeling the dynamics of forest community response to environmental gradients and disturbances over a mountain landscape. A gap model (FACET) was parameterized for species of various forest types (Tabonuco, Colorado, Dwarf and Palm), for many terrain conditions and was modified and extended to include species response to excess soil moisture and hurricanes. Landscape cover types were defined by dominance of species of each forest type and canopy height. Parameters of the landscape model (MOSAIC) were calculated from multiple runs of FACET. These runs were determined by combining terrain variables (elevation and soil) and hurricane risk. MOSAIC runs were analyzed for distribution patterns. Geographic Information Systems software was used to process terrain variables, hurricane risk and MOSAIC model output.
