Alexander Von Humboldt And Nineteenth-Century Ideas On The Origin Of American Indians, Michael Anthony Wadyko

Graduate Theses, Dissertations, and Problem Reports (ETD)

This dissertation revolves around Alexander von Humboldt's research on Indian origins. Humboldt conducted investigations on Indians during his precedent-setting scientific expedition to Meso- and South America during the years 1799--1804. Officially sponsored by the Spanish crown, the main purposes for this expedition were twofold: to examine, evaluate, and discredit Buffon's "degeneracy" claims about America and its inhabitants, and to gather empirical evidence on geography, climate, flora, fauna, and the indigenous cultures. From these results Humboldt published three major works about the expedition, particularly a thirty-volume work condensed to two volumes, Vues de Cordilleres et monuments des peuples d' Amerique.;From this …

Characterization Of The Airway Epithelial Bioelectric Mechanisms Associated With The Effects Of Epithelium-Derived Relaxing Factor In Guinea Pig-Isolated Trachea, Richard Alan Johnston

Graduate Theses, Dissertations, and Problem Reports (ETD)

In response to elevated serosal or mucosal tonicity, guinea-pig tracheal epithelium releases the non-nitric oxide, non-prostanoid, epithelium-derived relaxing factor (EpDRF), which subsequently diffuses to the underlying airway smooth muscle to initiate relaxation. Hypertonicity-induced smooth muscle relaxation via EpDRF involves epithelial Na+ and Cl- channels and is preceded by a depolarization of the transepithelial potential difference (Vms). By utilizing two different experimental systems, this study sought to characterize further the airway epithelial bioelectric mechanisms associated with the effects of EpDRF in guinea-pig isolated trachea.;First, this study attempted to elucidate which epithelial ion channels and/or transporters are involved in the depolarization of …

Hazardous Materials Database, Veena Vadiala

Graduate Theses, Dissertations, and Problem Reports (ETD)

Handling and disposal of a retired object can be a major component of its Life Cycle Cost. Often, during dismantling of a retired object many hazardous materials are released. Disposal of hazardous materials also need to comply with various federal regulations. Agencies like Occupational Safety and Health Administration (OSHA) and the Environmental Protection Agency (EPA) set these safety regulations. It is possible to apply generic exposure and release controls to protect workers from hazardous materials. For the most cost effective hazard controls it is necessary first to identify the materials and their properties of primary concern. There is a need …

Dynamic Property Evaluation Of Frother, Yunkai Xia

Graduate Theses, Dissertations, and Problem Reports (ETD)

Fourteen solvents were evaluated through frothing test and laboratory flotation batch tests. A new frothing parameter, initial dynamic froth index (IDFI), is proposed to compare the frothability of solvent. IDFI is derived from initial retention time of froth instead of retention time. IDFI is defined as the limiting slope of the initial retention time versus concentration curves while the concentration approaches zero. IDFI value depends on chemical structure and molecular weight of the solvent. Combined with normalized frothability index (NFI), normalized collapse rate constant (NKc), hydrophilic-lipophilic balance (HLB) and dynamic froth index (DFI), IDFI can be a useful index in …

Increasing Nutrition Knowledge And Food-Related Behavior Practices Among Participants In The "Dining With Diabetes" Program In West Virginia, Amy B. O'Dell

Graduate Theses, Dissertations, and Problem Reports (ETD)

Diabetes is a serious disease that effects a large number of West Virginia's population. A study was conducted using 591 diabetic and non-diabetic subjects who attended the "Dining with Diabetes" program. Subjects completed a demographic form, pretest, and posttest. Pearson's correlation and ANOVA were used to determine the effect of a diabetes intervention program on nutrition knowledge, diabetes behaviors, and practices. The results indicated that there was no significant difference in nutrition knowledge between diabetic and non-diabetic subjects. Interaction was noted when subjects were placed into groups based on their pretest score (p < 0.07). The change in score (posttest score-pretest score) was negatively correlated with pretest score (r = -0.75, p < 0.00). Significant association was also noted between nutrition knowledge score and several behavior and diabetic practices. The results conclude that diabetes education programs may significantly affect some behaviors and diabetic practices.

Essential Oil Treatments To Control Varroa Destructor Anderson And Trueman 2000 (Formerly Varroa Jacobsoni Oudemans 1904) (Mesostigmata: Varroidae), Maria Mercedes Vargas-Sarmiento

Graduate Theses, Dissertations, and Problem Reports (ETD)

Varroa destructor Anderson and Trueman is the most serious pest of the honey bee Apis mellifera L. Varroa mites transmit several viruses, bacteria and fungi to the bees, which results in a condition called parasitic mite syndrome. There are no completely reliable treatments available to control the mite. Fifty-one beehives were artificially infested with varroa mites by using three different methods. Observations on mite population growth during three infestation attempts were made. All colonies were inspected for the presence of the small hive beetle, Aethina tumida Murray, no beetles were found. Thirty-five colonies were used to establish the efficacy of …

Effect Of Manufacturing Process Conditions On The Durability Of Pultruded Vinyl Ester/Glass Composites, Chrystal Ann Garland

Graduate Theses, Dissertations, and Problem Reports (ETD)

Fiber reinforced polymer composites, FRPs, have an increased role in structural applications. Environmental durability is important for the design of structural components. Processes such as pultrusion are cost-effective methods of producing FRPs. This research focused on the durability of pultruded FRP with different processing conditions. Pultruded samples made at different line speeds (4, 8, and 12 ipm) were immersed in water at 25, 50, and 85°C for varying lengths of time and the mechanical properties evaluated via 3-point bending tests. A reduction in strength was observed for the samples immersed in 50 and 85°C water, with the largest reduction occurring …

Evaluation Of Survival And Recovery Characteristics Of Bifidobacteria As Indicators Of Fecal Pollution Of Water, John Elmer Ravenscroft Jr.

Graduate Theses, Dissertations, and Problem Reports (ETD)

The examination of aquatic environments for bacterial indicator organisms has proven to be a useful and well-established practice for the purpose of monitoring microbiological water quality. An ideal indicator of fecal pollution should be present in sufficient density to allow detection, present simultaneous with pathogen(s), incapable of aftergrowth in external aquatic environments, easy to enumerate, and exclusively of fecal origin. Unfortunately, none of the indicator organisms presently in use today meet all of these requirements. Bifidobacteria show promise as indicators of fecal pollution in water with the additional ability of potentially distinguishing between fecal pollution of human and animal origin. …

Teacher Videotaping As A Method Of Self -Assessing Questioning Skills In Secondary Public Schools, Stephen Alan Alberts Ii

Graduate Theses, Dissertations, and Problem Reports (ETD)

Primarily this action research project was designed to hone my ability to Socratically question students by reflecting on my teaching through the lens of a videocamera---while reconciling my own paradigm with as many outside assessment devices as possible. The paramount consideration of my questioning/framing references was to incite students to think critically (see Pedagogical Skills Honed in chapter seven). The higher priorities of the outside assessors, on the other hand, were more political than instructional in nature (see Reconciling Multiple Assessments in chapter seven).;Scrutinizing and improving my questioning skills (the focus of the research) led to the epiphany that the …

Formal Specification Of Requirements For Analytical Redundancy-Based Fault -Tolerant Flight Control Systems, Diego Del Gobbo

Graduate Theses, Dissertations, and Problem Reports (ETD)

Flight control systems are undergoing a rapid process of automation. The use of Fly-By-Wire digital flight control systems in commercial aviation (Airbus 320 and Boeing FBW-B777) is a clear sign of this trend. The increased automation goes in parallel with an increased complexity of flight control systems with obvious consequences on reliability and safety. Flight control systems must meet strict fault-tolerance requirements. The standard solution to achieving fault tolerance capability relies on multi-string architectures. On the other hand, multi-string architectures further increase the complexity of the system inducing a reduction of overall reliability.;In the past two decades a variety of …

Deference And Disability Discrimination, Rebecca Hanner White

Michigan Law Review

For thirty-five years, the civil rights community has paid scant attention to administrative law principles. Those interested in advancing on-the-job equality for this country's working men and women (or in preserving employer autonomy vis-a-vis federal encroachment) have all but ignored what many consider the arcane technicalities of administrative law. This state of affairs is strange when one considers that administration and enforcement of each of our major federal laws outlawing employment discrimination have been confided to an administrative agency, the Equal Employment Opportunity Commission ("EEOC"). The EEOC, however, has historically been given short shrift by litigants and by the judiciary. …

Works Of Men, Paul N. Akin, Jr.

Electronic Theses and Dissertations

True contentment is a thing as active as agriculture. It is the power of getting out of any situation all that there is in it. It is arduous and it is rare. It is the discipline of Epiphany. — G. K. Chesterton

Each of these stories has something to do with the idea of epiphany, as I mean it, the appearance or manifestation of something that wasn’t present before. The characters in the five stories all have something they are active about, which they are doing in the hopes of some measure of contentment. My interest was to pay attention …

Theoretical Structure Of Dynamic Gtap, Elena Ianchovichina, Robert Mcdougall

GTAP Technical Papers Archive

This paper documents the foreign asset ownership and investment theory of the dynamic GTAP model (GTAP-Dyn). The new investment theory offers a disequilibrium approach to modeling endogenously international capital mobility. It permits a recursive solution procedure, a feature that allows easy implementation of dynamics into any static AGE model without imposing limitations on the model's size. The method involves treating time as a variable, not as an index. Having time as a variable allows the construction of dynamic GTAP with minimum modifications to the existing structure of GTAP, by separating the theory of static GTAP from the length of run.

The Influence Of Base Sheet Sizing On The Print Quality Of Matte Coated Ink Jet Papers, Saurabh K. Halwawala

Masters Theses

The most recent developments in ink-jet papers have been related to coating aμd pigment technology. Silica is the preferred pigment for matte coated ink-jet papers. Besides being expensive, the high surface area and porosity of this pigment limits the percentage coating solids to less than 30-35%, which increases production cost due to higher dryer loads. Thus, a need exists to develop a new generation of pigments. The objective of this research was to evaluate the effect of base sheet absorbency on the surface, as well as print properties of matte coated ink-jet papers using a new pigment capable of being …
