Theoretical Prediction Of Drug Release In Gi Tract From Spherical Matrix Systems, Naga Lakshmi Ramana Susarla

Dissertations

The significance of controlled release drug delivery systems (CRDDS) lies in their ability to deliver the drug at a steady rate thus reducing the dosage interval and providing a prolonged pharmacodynamic effect. But despite the steadily increasing practical importance of these devices, little is known regarding their underlying drug release mechanisms. Mathematical modeling of these drug delivery systems could help us understand the underlying mass transport mechanisms involved in the control of drug release. Mathematical modeling also plays an important role in providing us with valuable information such as the amount of drug released during a certain period of time …

Dispersion Of Particles On Liquid Surfaces, Sathishkumar Gurupatham

Dissertations

When small particles (e.g., flour, pollen, etc.) come in contact with a liquid surface, they immediately disperse. The dispersion can occur so quickly that it appears explosive, especially for small particles on the surface of mobile liquids like water. This explosive dispersion is the consequence of capillary force pulling particles into the interface causing them to accelerate to a relatively large velocity. The maximum velocity increases with decreasing particle size; for nanometer-sized particles (e.g., viruses and proteins), the velocity on an air-water interface can be as large as 47 m/s. They also oscillate at a relatively high frequency about their …

The Impact Of Dynamic And Passive Standing On Bone Mineral Density And Appositional Growth In Immobilized Children, Megan Diane Damcott

Dissertations

The first discovery of the potential role that mechanical loading has on determining the strength of bone occurred in 1892. However, for almost a century after this discovery, the specific mechanisms influenced by mechanical loading remained locked in a mysterious 'black box'. Then in the 1960s, the 'black box' was opened and continued work has now unlocked the basic mechanisms involved in mechanical loading and whole-bone strength. This increased knowledge has spurred clinicians and researchers to investigate the impact of weight-bearing interventions on individuals with an increased risk of osteoporosis. The most common weight-bearing clinical intervention used in non-ambulant populations …

From "The Projects" To Houses : Physical Redevelopment, Poverty Deconcentration, And Resident Self-Sufficiency Impacts On Public Housing Residents At Hope Iv Developments In Camden, New Jersey, Michael C. Brown

Dissertations

Since 1992, public housing authorities (PHAs) throughout the United States have been building public housing rental and owner-occupied housing in place of demolished or rehabilitated distressed public housing and simultaneously attempting to deconcentrate poverty and improve self-sufficiency among the affected residents. The distressed housing is usually dilapidated, poorly designed, poorly constructed, poorly maintained, and poorly managed; the residents are very poor, are in constant fear of crime and violence, and have little hope. Previous attempts to address these problems have been piecemeal and often inadequate.

Based on recommendations by the National Commission on Severely Distressed Public Housing in 1992, the …

The Effects Of Periodic And Non-Periodic Inputs On The Dynamics Of A Medial Entorhinal Cortex Layer Ii Stellate Cell Model, Dongwook Kim

Dissertations

Various neuron types exhibit sub-threshold and firing frequency resonance in which the sub-threshold membrane potential or firing frequency responses to periodic inputs peak at a preferred frequency (or frequencies). Previous experimental work has shown that medial entorhinal cortex layer II stellate cells (SCs) exhibit sub-threshold and firing frequency resonance in the theta frequency band (4 - 10 Hz). In this thesis we seek to understand the biophysical and dynamic mechanism underlying these phenomena and how they are related. We studied the effects of sinusoidal current and synaptic conductance inputs at various frequencies, with and without noise, on the supra-threshold dynamics …

Multifunctional Reactive Nanocomposite Materials, Demitrios Stamatis

Dissertations

Many multifunctional nanocomposite materials have been developed for use in propellants, explosives, pyrotechnics, and reactive structures. These materials exhibit high reaction rates due to their developed reaction interfacial area. Two applications addressed in this work include nanocomposite powders prepared by arrested reactive milling (ARM) for burn rate modifiers and reactive structures. In burn rate modifiers, addition of reactive nanocomposite powders to aluminized propellants increases the burn rate of aluminum and thus the overall reaction rate of an energetic formulation. Replacing only a small fraction of aluminum by 8Al•MoO₃ and 2B•Ti nanocomposite powders enhances the reaction rate with little change …

Understanding Forgiveness Through The Application And Extension Of The Enright Forgiveness Inventory To Female Caregivers And A Community Sample Of Female Spouses, Lauren Nicole Decaporale

Dissertations

Despite recent increased attention to the construct of forgiveness, measures of forgiveness have been limited by inconsistent use of a single operational definition. One measure of forgiveness, the Enright Forgiveness Inventory (EFI), has shown strong psychometric properties in numerous studies and across diverse samples. However, limited research has explored the conceptualization and measurement of the forgiveness process with older adults and caregivers. The current study examined the utility of the EFI within a sample of 118 middle-aged and older female spouses, including a subset of dementia family caregivers (n = 29). Participants completed measures of religious coping, depression, state and …

Economic Returns Of The Occupational Education Experience Based On Two Missouri Community Colleges, Dianna Parker

Dissertations

A commonly held belief is that formal education has a strong positive association with earnings (Sanchez, 1998). The motivation for individuals to pursue and complete an education beyond high school is likely founded in the hopes of higher paying jobs or a higher position. The “economic benefits” of a community college education can be defined as the gain in personal earnings over time because of the skills and knowledge acquired, as reflected in credit hours completed, at the community college. The purpose of this study was to determine how the skills, knowledge, and credentials obtained in community college occupational courses …
