Estimated Sales And Investment Costs To Produce And Retail Gelato In The Petaluma Area, Katherine Camozzi

Agribusiness

Recent events in the California dairy have left many dairy producers with high feed costs, low profits, and low (sometimes negative) margins. Some producers have transitioned to producing value-added or artisanal dairy products to help increase the revenues earned from farm milk, particularly in Sonoma County. Because limited research exists on the business opportunities in response to a rapidly growing market for value-added products, this project explores the feasibility of starting a gelato production and retail business in the Petaluma area. To assess business feasibility, a consumer survey was created to estimate the percent of residents and non-residents who would …

Form-Based Codes, Design Guidelines And Placemaking: The Case Of Hayward, Ca., Cindy Ma

Master's Theses

Throughout history planning codes and standards have been used to regulate the built environment for health, power, order, and economic reasons. More recently, in the urban design and planning field, planning codes and standards have emerged to become tools in the process of “placemaking”. The concept of placemaking builds from the desire of humans to create places, not spaces, which are unique, attractive, identifiable, and memorable. It is a concept that is comprised of visual and social components, recognizing the need for both in the creation of successful places. In the field of urban design and planning, form-based codes (FBCs) …

Application Of A Heuristic Method To A Water Distribution System For Determining Optimal Water Quality Monitoring Locations, Lawrence David Johnson

A Proteomic Analysis Of Differentiation In The Mammary Epithelium, Laura Therese Strand

Master's Theses

While a great deal is known about the changing hormonal environment and the structural development of the mammary gland from pregnancy to lactation, very little is known about the molecular mechanisms governing differentiation of the mammary epithelium into a milk-secreting phenotype. It is important to acknowledge the diversity among the mammary glands of different species in order to better understand applications in human health and the dairy industry. In this study, we examined global protein expression during two states of differentiation in mammary epithelial cells from two species: in vitro proliferating and differentiated MAC-T cells (a bovine immortal cell-line), and …

The Development Of Transparent, Processable, Thermally-Responsive Coatings, Christopher David Roland

Master's Theses

Polymer matrices are commonly used as guest-host systems for organic chromophores for use in non-linear optical materials. The chromophores must be aligned or poled in an electric field in order to impart anisotropy and non-linear activity to the material. This poling process raises several issues, the two largest being the eventual relaxation of the chromophores back into random orientations due to brownian motion, and high molecular weight polymer matrices limiting chromophore mobility during poling. The prevention of this relaxation process is an area of significant interest, especially in applications that require long term coating stability and activity. In this study, …

Development Of A Blood Flow Measurement Protocol Using Particle Image Velocimetry, Jennifer Chi-Ying Go

Biomedical Engineering

Peripheral Arterial Occlusive Disease (PAOD) is an acquired inflammatory disease where a peripheral artery becomes occluded due to the buildup of atherosclerotic plaques. In patients that possess collateral arteries, an occlusion can lead to shear induced outward remodeling, arteriogenesis, of these collaterals, partially restoring blood flow. However, newly remodeled collaterals exhibit reduced functional vasodilation, which may impair normal activity, such as ambulation. To model chronic ischemia and arteriogenesis in collaterals, a femoral artery ligation in a murine hindlimb is commonly performed. Previous efforts by our group involved measurements of collateral artery diameter to assess the impact of arteriogenesis on functional …
