An Analytical Technique For Solving Nonlinear Heat Transfer Equations, Hossein Aminikhah, Milad Hemmatnezhad Dec 2010

An Analytical Technique For Solving Nonlinear Heat Transfer Equations, Hossein Aminikhah, Milad Hemmatnezhad

Applications and Applied Mathematics: An International Journal (AAM)

In this paper, an analytic technique, namely the New Homotopy Perturbation Method (NHPM) is applied for solving the nonlinear differential equations arising in the field of heat transfer. In this method, the solution is considered as an infinite series expansion where converges rapidly to the exact solution. The nonlinear convective–radioactive cooling equation and nonlinear equation of conduction heat transfer with the variable physical properties are chosen as illustrative examples and the exact solutions have been found for each case.


Finite Element Analysis In Porous Media For Incompressible Flow Of Contamination From Nuclear Waste, Abbas Al-Bayati, Saad A. Manaa, Ekhlass S. Ahmed Dec 2010

Finite Element Analysis In Porous Media For Incompressible Flow Of Contamination From Nuclear Waste, Abbas Al-Bayati, Saad A. Manaa, Ekhlass S. Ahmed

Applications and Applied Mathematics: An International Journal (AAM)

A non-linear parabolic system is used to describe incompressible nuclear waste disposal contamination in porous media, in which both molecular diffusion and dispersion are considered. The Galerkin method is applied for the pressure equation. For the brine, radionuclide and heat, a kind of partial upwind finite element scheme is constructed. Examples are included to demonstrate certain aspects of the theory and illustrate the capabilities of the kind of partial upwind finite element approach.

Long-Term Hypoxia Regulates Cortisol Biosynthesis In The Ovine Fetal Adrenal Cortex, Vladimir Enrique Vargas Dec 2010

Long-Term Hypoxia Regulates Cortisol Biosynthesis In The Ovine Fetal Adrenal Cortex, Vladimir Enrique Vargas

Loma Linda University Electronic Theses, Dissertations & Projects

Previous studies demonstrated enhanced fetal adrenal cortisol biosynthesis following exposure to long-term hypoxia (LTH). The studies presented here were designed to determine the mechanism(s) regulating this important adaptive endocrine response. Ewes were maintained at high altitude (3,820 m) from approximately day 40 to 138-141 of gestation. Fetal adrenal glands were then collected from LTH and age matched normoxic controls. Dispersed fetal adrenal cortical cells (FACs) were untreated, treated with ACTH, treated in combination with ACTH precursors (POMC and 22-kDa pro-ACTH), or pre-treated with H-89 and or UO126 followed by ACTH treatment. Following ACTH treatment, cortisol biosynthesis increased in both groups …


Amending Constituting Identity, Rosalind Dixon Dec 2010

Amending Constituting Identity, Rosalind Dixon

Public Law and Legal Theory Working Papers

Constitutional amendment procedures can create constitutional change in two ways: by providing evidence of popular support for constitutional change, and by changing the textual basis for subsequent acts of constitutional interpretation. Both mechanisms have clearly also succeeded, in various countries, in creating changes in the domain of constitutional identity. The question the essay investigates is whether there is nonetheless something peculiar about this domain that makes it especially difficult to succeed in using both these amendment mechanisms, simultaneously, in the quest for constitutional change. To explore this question, the essay draws on two distinct attempts to “amend” constitutional identity in …


Characterizing And Treating The Neuropathology Of Tuberous Sclerosis Complex In The Mouse, Sharon W. Way Dec 2010

Characterizing And Treating The Neuropathology Of Tuberous Sclerosis Complex In The Mouse, Sharon W. Way

Dissertations and Theses (Open Access)

Tuberous sclerosis complex (TSC) is a multisystem, autosomal dominant disorder affecting approximately 1 in 6000 births. Developmental brain abnormalities cause substantial morbidity and mortality and often lead to neurological disease including epilepsy, cognitive disabilities, and autism. TSC is caused by inactivating mutations in either TSC1 or TSC2, whose protein products are known inhibitors of mTORC1, an important kinase regulating translation and cell growth. Nonetheless, neither the pathophysiology of the neurological manifestations of TSC nor the extent of mTORC1 involvement in the development of these lesions is known. Murine models would greatly advance the study of this debilitating disorder. This thesis …


Analysis Of Β8 Integrin In Neurogenesis And Neurovascular Homeostasis, Aaron K. Mobley Dec 2010

Analysis Of Β8 Integrin In Neurogenesis And Neurovascular Homeostasis, Aaron K. Mobley

Dissertations and Theses (Open Access)

Neurogenesis in the adult mouse brain occurs within the subventricular zone (SVZ) of the lateral ventricle. In the SVZ, neural stem cells (NSC) reside in a specialized microenvironment, or vascular niche, consisting of blood vessels and their basement membranes. Most NSCs in the SVZ differentiate into progenitor cells, which further differentiate to generate neuroblasts, which then migrate from the SVZ to the olfactory bulbs (OB) along the rostral migratory stream (RMS). ECM-mediated adhesion and signaling within the vascular niche likely contribute to proper NSC self-renewal, survival, differentiation and neuroblast motility. The mechanisms that control these events are poorly understood. Previous …


Technology Convergence And Federalism: Who Should Decide The Future Of Telecommunications Regulation?, Daniel A. Lyons Dec 2010

Technology Convergence And Federalism: Who Should Decide The Future Of Telecommunications Regulation?, Daniel A. Lyons

University of Michigan Journal of Law Reform

This Article critically examines the division of regulatory jurisdiction over telecommunications issues between the federal government and the states. Currently, the line between federal and state jurisdiction varies depending on the service at issue. This compartmentalization might have made sense fifteen years ago, but the advent of technology convergence has largely rendered this model obsolete. Yesterday's telephone and cable companies now compete head-to-head to offer consumers the vaunted "triple play" of voice, video, and internet services. But these telecommunications companies are finding it increasingly difficult to fit new operations into arcane, rigid regulatory compartments. Moreover, services that consumers view as …


Undoing Undue Favors: Providing Competitors With Standing To Challenge Favorable Irs Actions, Sunil Shenoi Dec 2010

Undoing Undue Favors: Providing Competitors With Standing To Challenge Favorable Irs Actions, Sunil Shenoi

University of Michigan Journal of Law Reform

The Internal Revenue Service occasionally creates rules, notices, or regulations that allow taxpayers to pay less than they would under a strict reading of the law. Sometimes, however, these IRS actions are directly contrary to federal law and have significant economic impact. Challenging favorable IRS actions through litigation will likely be unsuccessful because no plaintiff can satisfy the requirements for standing. To address this situation, this Note proposes a statutory reform to provide competitors with standing to challenge favorable IRS actions in court.

A Generational Look Into The Occurrence Of Child Maltreatment Among Latinos And Their Effects On Developmental Growth, Maria Teresa Sanchez Diosdado Dec 2010

A Generational Look Into The Occurrence Of Child Maltreatment Among Latinos And Their Effects On Developmental Growth, Maria Teresa Sanchez Diosdado

Psychology and Child Development

Little is known about the prevalence or risk factors associated with child maltreatment among Latino immigrant and native born families. As a result, Latino children and families are often treated as a homogeneous group, with little understanding of the potential differences that may exist between immigrant and native-born families. This paper attempts to explain the concept of child maltreatment and explore the differences between the two groups, while taking into account the effects of acculturation, Belsky’s Ecological Model of Maltreatment, childrearing practices, and the developmental consequences of maltreatment. Finally, the role that Child Protective Services plays in this issue will …

Barelas Rail Yard Redevelopment: A Stakeholder Assessment, Michael W. Furze

Architecture and Planning ETDs

Community-based redevelopment of Albuquerque, New Mexicos twenty-seven acre Barelas Rail Yard site represents one possible outcome of the ongoing redevelopment process. This thesis uses semistructured interviews with neighborhood residents and community activists to reveal visions and concerns about the future of the site from beyond the profit-driven approach of typical contemporary projects. Through interviews and the case studies, I provide recommendations for discussion and capacity-building that allows neighborhood residents to better navigate a complex political landscape and influence the redevelopment of the site through a community-based process that brings together multiple visions of renewed activity on the site that respects …


Structure Of Narratives: Applying Propp's Folktale Morphology To Entertainment-Education Films, Divya Sreenivas Dec 2010

Structure Of Narratives: Applying Propp's Folktale Morphology To Entertainment-Education Films, Divya Sreenivas

Communication ETDs

This study examines narrative strategies through which feature films accomplish the dual role of entertainment-education to shape social reality surrounding health issues. More specifically, exploring films' narrative structures and characterization, this study illuminates how a coherent HIV/AIDS narrative is woven into cinematic artifacts laden with specific cultural values, beliefs and practices. The entertainment-education literature has rarely undertaken a study of films to demonstrate their entertainment-education potential. Moreover, by taking a structuralist perspective and utilizing narrative theories this study uncovers underlying elements that cut across narratives. According to Fisher (1987), the proponent of narrative theory, narratives are moral constructs with values …


Staphylococcus Aureus Virulence Factors Synthesis Is Controlled By Central Metabolism, Yefei Zhu Dec 2010

Staphylococcus Aureus Virulence Factors Synthesis Is Controlled By Central Metabolism, Yefei Zhu

School of Veterinary and Biomedical Sciences: Dissertations, Theses, and Student Research

Staphylococcus aureus is a versatile pathogen that can survive in diverse host environments. This versatility depends on its ability to sense nutrients and respond by modulating gene expression, including the synthesis of virulence determinants. In addition to its ability to synthesize virulence factors, the capacity of S. aureus to form biofilms is an important mediator of virulence in certain infections. Biofilms are a complex aggregation of bacteria commonly encapsulated by an adhesive exopolysaccharide matrix (polysaccharide intercellular adhesin; PIA). To study S. aureus biofilm formation, we assessed the metabolic requirements of S. aureus growing in a biofilm and …


The In Situ Function Of A Microbial Community Profiled By Ft-Ir: A Snapshot In Time, Ryan Roberts Dec 2010

The In Situ Function Of A Microbial Community Profiled By Ft-Ir: A Snapshot In Time, Ryan Roberts

Department of Biochemistry: Dissertations, Theses, and Student Research

Photographs of an ecosystem are an important tool in macro-community ecology. The photograph is a permanent record of species phenotype. In microbiology, biochemical activity provides the most descriptive information of an organism’s phenotype. A method for fingerprinting all biochemical activities occurring within a microbial community is analogous to a photograph. Infrared spectroscopy in the region between wavelengths 2500 to 20,000 nm (mid-IR) is a well established instrumental method for fingerprinting the total biochemical profile of axenic cultures. Spectra are complex and sensitive as demonstrated by the ability to discriminate between strains of bacteria, fungi, and algae. This thesis develops the …

Geophysics At The Interface: Response Of Geophysical Properties To Solid-Fluid, Fluid-Fluid, And Solid-Solid Interfaces, R. Knight, L. J. Pyrak-Nolte, L. Slater, E. Atekwana, A. Endres, J. Geller, D. Lesmes, S. Nakagawa, A. Revil, M. M. Sharma, C. Straley

Department of Physics and Astronomy Faculty Publications

Laboratory studies reveal the sensitivity of measured geophysical properties to solid-fluid, fluid-fluid, and solid-solid interfaces in granular and fractured materials. In granular materials, electrical properties and nuclear magnetic resonance relaxation times exhibit a strong dependence on the size and properties of the solid-fluid interface. The electrical and seismic properties of granular materials and the seismic properties of fractured materials reveal a dependence on the size or geometry of fluid-fluid interfaces. Seismic properties of granular and fractured materials are affected by the effective stress and cementing material at solid-solid interfaces. There have been some recent studies demonstrating the use of field-scale …

Marketing Business Languages: Teaching Students To Value And Promote Their Coursework, Annie Abbott, Darcy Lear

Global Business Languages

Students in business language courses develop and refi ne important professional skills, but not all students successfully communicate those academic experiences in their professional job search materials. In this article we first detail what employers expect of recent college graduates and match these qualities to innovative practices in business language curricula. Then we present two in-depth examples of business language course content that includes classroom activities and assessment items in which students articulate in business terms what they have learned in their academic course. Building these explicit steps into the course curriculum helps students recognize for themselves the professional value …


Teaching Intercultural Communication In A Professional Language Course, Michael Hager Dec 2010

Teaching Intercultural Communication In A Professional Language Course, Michael Hager

Global Business Languages

In the following article, we will discuss culture instruction and the necessity to include information about the native culture. Culture instruction can also include stereotypes in order to permit students to confront their own use of stereotypes. Then we discuss background information about culture, including self-construal, the distinction between independent and interdependent cultures, and paradigm shifting. This background information provides the basis for demonstrating how culture can be taught in a business German course by using, for example, marketing and culture assimilators.
