Chef Sifty, Dereck Quock

Computer Engineering

In our society today, childhood obesity has become a more prevalent problem, which needs to be fixed. Children constantly eat and snack unhealthily and parents need to understand the importance of teaching children how food affects their body and well-being. Teaching this to children at an early age will help to instill a healthy lifestyle for the child. Chef Sifty is a cooking game developed for Sifteo cubes that aims to show children the importance of nutrition while having fun. Using Sifteo’s concept of Intelligent Play, the objective of this project is to show children some healthy food and snack …

Deciding Not To Decide: Deferral In Constitutional Design, Rosalind Dixon, Tom Ginsburg

Public Law and Legal Theory Working Papers

In designing constitutions, constitutional drafters often face constraints that cause them to leave things “undecided”—or to defer decision-making on certain constitutional issues to the future. They do this both through adopting vague constitutional language, and through specific language that explicitly delegates issues to future legislators (i.e. “by law” clauses). The aim of this article is to deepen our understanding of this second, to date largely un-examined, tool of constitutional design. We do so by exploring: (1) the rationale for constitutional deferral generally; (2) the potential alternatives to “by law” clauses as a means of addressing concerns about constitutional “error” and …

Methodologies for determining the proper size and layout of heliostats, optimal tower height, receiver size, and turbine engine selection are developed. In this specific design, solar shares of up to 73.2% …

The First Amendment's Epistemological Problem, Paul Horwitz

Washington Law Review

In this Article, I treat the recent interest in these epistemological issues as an opportunity to explore an important aspect of Post’s project: the uneasy role of truth within First Amendment doctrine, and the relationship between courts and those institutions that we view generally as epistemically reliable sources of knowledge. My examination suggests that the First Amendment faces what I call an epistemological problem: specifically, the problem of figuring out just how knowledge fits within the First Amendment. The growing attention to the epistemology problem among leading First Amendment scholars is significant enough to warrant examination. Although I offer some …

Evaluation Of Textural Properties Of Cooked Beef Batters, Lee M. Christensen

Master's Theses

In the meat science industry the primary method used to determine the binding capabilities of a raw material is to reference the binding index created by Carpenter and Saffle (1964). This index is primarily based on the emulsification capabilities of meats and does not consider texture. As texture is one of the principal factors in determining acceptability of foods (Bourne, 1978), a testing method that captures textural attributes of raw materials is essential. This work was developed to capture raw material texture and cooking loss in a relatively quick manner.

Textural properties of cooked beef batters using two different salt …

Viscoelastic Anisotropic Finite Element Mixture Model Of Articular Cartilage Using Viscoelastic Collagen Fibers And Validation With Stress Relaxation Data, Matthew Alexander Griebel

Master's Theses

Experimental results show that collagen fibers exhibit stress relaxation under tension and a highly anisotropic distribution. To further develop the earlier model of Stender [1], the collagen constituent was updated to reflect its intrinsic viscoelasticity and anisotropic distribution, and integrated with an existing mixture model with glycosaminoglycans and ground substance matrix. A two-term Prony series expansion of the quasi-linear viscoelastic model was chosen to model the viscoelastic properties of the collagen fibers. Material parameters were determined by using the simplex method to minimize the sum of squared errors between model results and experimental stress relaxation data of tissue in tension. …

Becoming Cittaslow: A City's Journey To Becoming A Cittaslow Member, Megan Alexis Elovich

Master's Theses

The project will explore Cittaslow as an alternative to traditional urban development. Sprawl and consumption of non-local resources are discouraged with Cittaslow and preservation of culture and history become the tangible benchmarks of the community. It will explore the history of Cittaslow as a movement and an organization; as well as its influences on existing member cities and the criteria used to distinguish them from others. The City of San Luis Obispo is used as a case study to determine whether existing conditions measure up to Cittaslow criteria.

3d Electromagnetic Simulation Tool Exposure For Undergraduate Electrical Engineers: Incorporation Into An Analog Filters Course, Bobby B. Pheng

Master's Theses

With the growth of wireless communications, comes the need for engineers knowledgeable in 3D electromagnetic (EM) simulation of high-frequency circuits. To give electrical engineering students a better understanding of the behavior of electromagnetic fields, experiments including the use of 3D EM simulation software were proposed. Most students get lost in differential equations, curls, and divergences; this thesis aims to remedy that by exposing them to 3D EM simulation, which may motivate them toward further study in electromagnetics. Also, experience using EMPro is very beneficial for future RF/microwave/antenna engineers, as use of 3D EM simulation is becoming a requirement for this …

A Primer On Federal Grazing Fees, Larry W. Van Tassell

Cornhusker Economics

The federal government owns nearly 30 percent of the land area in the United States. The vast majority of this land lies in the western U.S. For example, 81 percent of Nevada’s, 63 percent of Utah’s, 61 percent of Idaho’s and 48 percent of Wyoming’s land mass is owned by the federal government. In contrast, 1.10 percent of Nebraska’s land mass is under federal ownership.

Most of the public lands in the western U.S. are under the jurisdiction of the U.S. Forest Service (USFS) or Bureau of Land Management (BLM), and many are utilized for livestock grazing. Fees for grazing …

The Changing Composition Of United States Agricultural Trade, E. Wesley F. Peterson

Cornhusker Economics

International trade has been of great importance for United States agriculture since the founding of the nation. Today, about 20 percent of agricultural production in the United States is exported, and the revenue from these exports is an important source of farm income. According to the Economic Research Service over half of U.S. wheat production is exported, as is almost 80 percent of U.S. cotton production. While agricultural exports are always greater than agricultural imports, U.S. consumers depend on imports for many commodities, notably such tropical goods as coffee, cocoa, bananas and other tropical fruits. The real values of U.S. …

Role Of The Pituitary-Adrenal Axis In G-Csf Therapy After Neonatal Hypoxia-Ischemia, Melissa Stephanie Charles

Loma Linda University Electronic Theses, Dissertations & Projects

Several reports indicate that the activity of the hypothalamic-pituitary-adrenal axis (HPA) as measured by the increased level of adrenocorticotropic hormone (ACTH), and corticosterone is increased after a brain insult. These hormones are the effectors secreted respectively by the pituitary and adrenal glands. It has been shown that the down-regulation of corticosterone levels can improve detrimental outcomes associated with ischemic brain injuries. Neonatal hypoxia-ischemia (HI) is a devastating perinatal event with a grim prognosis and limited therapeutic strategies. In recent studies, granulocyte-colony stimulating factor (G-CSF) has shown promise in neonatal HI investigations by improving neuromotor function and reducing apoptosis in the …

Analysis Of Minocycline As A Radioprotectant, Shalini Mehrotra

Loma Linda University Electronic Theses, Dissertations & Projects

Exposure to radiation is increasing in a variety of settings including space exploration, diagnostic medical procedures and radiotherapy. Cells of the hematopoietic system, such as white blood cells (WBC), are especially sensitive to radiation and their decline can result in Acute Radiation Syndrome (ARS). Radiotherapy is often used for cancers of the central nervous system (CNS), but includes the risk for normal tissue damage, often leading to cognitive impairment. The literature suggests that tetracyclines can be radioprotectors of the hematopoietic system with potential utility in radiation emergencies and anticancer radiotherapy. Minocycline, a semisynthetic tetracycline derivative, has anti-inflammatory, free radical scavenging, …

Buehrer, David J. Duffin, Y. Renee Lea-Currie, David Ribnicky, Ilya Raskin, Jacqueline M. Stephens, William T. Cefalu, Jeffrey M. Gimble

Faculty Publications

Plant extracts continue to represent an untapped source of renewable therapeutic compounds for the treatment and prevention of illnesses including chronic metabolic disorders. With the increase in worldwide obesity and its related morbidities, the need for identifying safe and effective treatments is also rising. As such, use of primary human adipose-derived stem cells represents a physiologically relevant cell system to screen for bioactive agents in the prevention and treatment of obesity and its related complications. By using these cells in a primary screen, the risk and cost of identifying artifacts due to interspecies variation and immortalized cell lines is eliminated. …

Vitronectin Inhibits Neutrophil Apoptosis Through Activation Of Integrin-Associated Signaling Pathways, Hong Beom Bae, Jaroslaw W. Zmijewski, Jessy S. Deshane, Degui Zhi, Lawrence C. Thompson, Cynthia B. Peterson, David D. Chaplin, Edward Abraham

Faculty Publications

Vitronectin is present in large concentrations in serum and the extracellular matrix. Although vitronectin is known to modulate neutrophil adhesion and chemotaxis, and to contribute to neutrophil-associated proinflammatory processes, a role in apoptosis has not been demonstrated. In thepresent studies,wefound that neutrophils demonstrated more rapid progression to spontaneous or TNF-related apoptosisinducing ligand-induced apoptosis when incubated under vitronectinfree conditions thanwhen vitronectinwas present. The ability of native vitronectin to delay neutrophil apoptosis was not recapitulated by the vitronectin somatomedin B domain. In contrast, inclusion of the cyclo[Arg-Gly-Asp-D-Phe-Val] peptide in cultures containing vitronectin resulted in enhanced neutrophil apoptosis, showing that the vitronectin RGD …

Innovation For Inclusive Growth: Towards A Theoretical Framework And A Research Agenda, Gerard George, Anita M. Mcgahan, Jaideep Prabhu

Research Collection Lee Kong Chian School Of Business

Inclusive innovation, which we define as innovation that benefits the disenfranchised, is a process as well as a performance outcome. Consideration of inclusive innovation points to inequalities that may arise in the development and commercialization of innovations, and also acknowledges the inequalities that may occur as a result of value creation and capture. We outline opportunities for the development of theory and empirical research around this construct in the fields of entrepreneurship, strategy, and marketing. We aim for a synthesis in views of inclusive innovation and call for future research that deals directly with value creation and the distributional consequences …

Is The Prosecution Of War Crimes Just And Effective? Rethinking The Lessons From Sociology And Psychology, Ziv Bohrer

Michigan Journal of International Law

Should perpetrators of genocide, violent acts against civilians during war, or other massive violations of core human rights be punished? International criminal law (ICL) answers this question affirmatively, asserting that the punishment of such atrocities is just and that their effective prosecution can (and should) contribute to the prevention of such future acts. Moreover, an increasing attempt has been made in the international and domestic arenas to act in accordance with these assertions of ICL through the prosecution of war crimes. During the last two decades the role of ICL has become gradually more significant, and the fall of the …

Predictive Musculoskeletal Simulation Using Optimal Control: Effects Of Added Limb Mass On Energy Cost And Kinematics Of Walking And Running, Antonie J. Van Den Bogert, Maarten Hupperets, Heiko Schlarb, Berthold Krabbe

Mechanical Engineering Faculty Publications

When designing sports equipment, it is often desirable to predict how certain design parameters will affect human performance. In many instances, this requires a consideration of human musculoskeletal mechanics and adaptive neuromuscular control. Current computational methods do not represent these mechanisms, and design optimization typically requires several iterations of prototyping and human testing. This paper introduces a computational method based on musculoskeletal modeling and optimal control, which has the capability to predict the effect of mechanical equipment properties on human performance. The underlying assumption is that users will adapt their neuromuscular control according to an optimality principle, which balances task …

Communicating Ethics: Analysis Of Annual Letters To Stakeholders, Christopher Bryan

Communication & Leadership Dissertations and Theses

This research examines how executives, leaders and managers communicate their sense of ethics. Literature from various disciplines is increasingly focusing on the strong ethical tone-at-the-top and strong ethical culture to prevent organizational wrongdoing. The literature suggests that leaders face unique challenges in communicating their ethics and that the communication of ethics is inhibited by a psychological bias and the work is grounded in the cultural communication theory of Geertz and Pacanowsky and the organizational culture work of Schein. The research focuses on CEO annual letters written to stakeholders. This form of communication is a high-profile channel of communication and written …
