Cost-Benefit Analysis Of Implementing Wastewater Treatment Facilities In Beer Breweries, Jaffer (Jeff) Shah-Ganai

Agribusiness

The purpose of this study was to both see the effects of wastewater on profitability as well as determine an efficient way of dealing with that wastewater. In addition to finding the most efficient way of treating wastewater, the cost of implementing such a technology was also discussed. Two technologies were specifically talked about and those were an anaerobic digester and a two stage anaerobic digester. Between the three breweries that were discussed, two of them use one of those pieces of equipment; Sierra Nevada has an anaerobic digester and Red Hook has a two stage anaerobic digester.

Kinesiology and Public Health

To provide a synthesis of research on trails and physical activity from the public health, leisure sciences, urban planning, and transportation literatures. Methods: A search of databases was conducted to identify studies published between 1980 and 2008. Results: 52 studies were identified. The majority were cross-sectional (92*%) and published after 1999 (11%). The evidence for the effects of trails on physical activity was mixed among 3 intervention and 5 correlational studies. Correlates of trail use were examined in 13 studies. Several demographic (eg, race, education, income) and environmental factors (eg, land-use mix and distance to trail) were related to trail …

Investigating The Roles Of Ndj1 And Tid1 In Crossover Assurance In Saccharomyces Cerevisiae, Rianna Knowles

Master's Theses

Meiosis is the specialized process of cell division utilized during gametogenesis in all sexually reproducing eukaryotes, which consists of one round of DNA replication followed by two rounds of chromosome segregation and results in four haploid cells. Crossovers between homologous chromosomes promote proper alignment and segregation of chromosomes during meiosis.

Crossover interference is a genetic phenomenon in which crossovers are non-randomly placed along chromosomes. Crossover assurance ensures that every homologous chromosome pair obtains at least one crossover during Prophase I. Crossovers physically connect homologous pairs, allowing spindle fibers to attach and separate homologs properly. However, some organisms have shown an …

Capstone Experiences: Effects Of Adapted Physical Activity Design Projects On Attitudes And Learning, David W. Hey, Bridie Jean Mccarey, Lynne A. Slivovsky, J. Kevin Taylor, Brian Self, James Widmann

Kinesiology and Public Health

Eight innovative senior level capstone engineering projects were completed at California Polytechnic State University (2008-present) involving (n=28) students (23 male/5 female). All projects involved the design of equipment to facilitate physical activity for people with disabilities. The effects on: i) learning design, ii) attitude towards people with disabilities, and iii) motivation to complete team design projects were analyzed through eight one-hour focus groups. This paper presents focus group findings using a constructivist approach and grounded theory to explore the overall student “learn by doing” experience. Results: (1) Approximately 19 (70%) of the students claimed the adapted physical activity …

Psychology and Child Development

Objective: This study investigated the role of self-regulation of emotion in relation to functional impairment and comorbidity among children with and without AD/HD. Method: A total of 358 probands and their siblings participated in the study, with 74% of the sample participants affected by AD/HD. Parent-rated levels of emotional lability served as a marker for self-regulation of emotion. Results: Nearly half of the children affected by AD/HD displayed significantly elevated levels of emotional lability versus 15% of those without this disorder. Children with AD/HD also displayed significantly higher rates of functional impairment, comorbidity, and treatment service utilization. …

Development And Prototyping Of A Ground Fault Circuit Interrupter For 3-Phase 480 Volt Systems, Matthew R. Norlander

Master's Theses

Ground Fault Circuit Interrupter (GFCI) technology was first introduced in the NEC in 1971, yet four decades later the technology has not been introduced to a great extent outside of the home environment. This thesis introduces the difficulties encountered in low-voltage three phase ground fault current detection, and adopts a previously patented tripping scheme to develop and prototype a digital relay for 3-phase 480 volt systems capable of the sensitivity and speed required for personnel safety. Results demonstrate the feasibility of the concept and suggest commercial development should be pursued. The prototype is capable of mA sensitivity and reliably detects …

Quantification Of Nitrate Sources And Sinks Using A Water Quality Network In Morro Bay Estuary, California, Johanna Nadia Jean Weston

Master's Theses

Using an instrumented water quality network in Morro Bay Estuary, California from 2007 to 2010 (15 min sampling frequency), this study addressed the two objectives of constructing a nitrate budget and assessing the influence of sampling frequency on water quality parameters. These two objectives led to the submission of an original report of research (Appendix A) and a note (Appendix B) to peer-reviewed journals.

The first objective was to characterize the high spatial and temporal variation in physical parameters and nitrate concentrations and to construct a nitrate budget quantifying sources and sinks of nitrate from the ocean, streams, and groundwater, …

Negotiating The Anthropological Limit. Derrida, Stiegler, And The Question Of The Animal, Nathan Van Camp

Between the Species

Although much has been written about the so-called political, ethical and religious turns in the thinking of Jacques Derrida, few have noticed that his late writings were marked by what we could tentatively call a “zoological turn.” This is surprising given that in The Animal That Therefore I Am Derrida clearly stated that the question as to what distinguishes the human from the animal has for him always been the most important question of philosophy. This essay will attempt to offer a preliminary exploration of this still largely uncharted aspect of Derrida’s thought. Starting from a brief overview of Derrida’s …

Educational Curriculum Standards & Standardized Educational Tests: Comparing Apples & Oranges?, William D. Stansfield

Biological Sciences

Mandated biology curriculum standards and standardized tests may vary widely from one state to another, making academic-performance comparisons among the states problematic. This report outlines the effects of the “No Child Left Behind” law and uses California as a test case against which teachers in other states may make comparisons of their own biology curriculum standards and tests. Several sources are cited that offer sample multiple-choice questions that have appeared on previous California standardized tests for sciences/life sciences/biology. These examples, and critique thereof, may help teachers better prepare their own tests to improve student performance in meeting the state's curriculum …

The (Mis)Use Of Disaster As Opportunity: Coerced Relocation From Celaque National Park, Honduras, Benjamin F. Timms

Social Sciences

“Disaster capitalism” refers to political economic processes that take advantage of mass trauma to impose neoliberal capitalist economic policies, facilitating the redistribution of wealth and exacerbating socio-economic divisions. Here the basic tenets of disaster capitalism are applied in another context: how natural disasters can be used to impose exclusionary protected area conservation principles with similar socio-economic consequences and ecological ramifications. The post-Hurricane Mitch relocation of resident populations from Celaque National Park, Honduras serves as a case study whereby a natural disaster, combined with the effects of neoliberal structural adjustment policies, created the opportunity to implement a universal model of exclusionary …

Season And Sex Of Host Affect Intensities Of Ectoparasites In Western Fence Lizards (Sceloporus Occidentalis) On The Central Coast Of California, Anthony S. Lumbad, Larisa K. Vredevoe, Emily N. Taylor

Biological Sciences

Seasonal variability in intensities of ectoparasites of western fence lizards (Sceloporus occidentalis) was quantified in spring, summer, and autumn 2008. Lizards were suspended over pans of water in the laboratory to enumerate replete western black-legged ticks (Ixodes pacificus) and mites. Intensity of ectoparasites was greatest in spring. On average, mites comprised the greatest proportion of ectoparasites, followed by larval and nymphal ticks, respectively. Mites were on lizards year-round. Overall intensity of ticks was greatest in spring, but low during summer and autumn. Males were more heavily parasitized by ticks than females in spring, whereas females had …

The Proteomic Response Of Sea Squirts (Genus Ciona) To Acute Heat Stress: A Global Perspective On The Thermal Stability Of Proteins, Loredana Serafini, Jay B. Hann, Dietmar Kültz, Lars Tomanek

Biological Sciences

Congeners belonging to the genus Ciona have disparate distributions limited by temperature. Ciona intestinalis is more widespread with a cosmopolitan distribution ranging from tropical to sub-arctic zones, while Ciona savignyi is limited to temperate-latitudes of the northern Pacific Ocean. To compare the heat stress response between congeners, we quantified changes in protein expression using proteomics. Animals were exposed to 22 °C, 25 °C, and 28 °C for 6 h, then recovered at a control temperature (13 °C) for 16 h (high heat stress experiment). In a second experiment we exposed animals to lower levels of heat stress at 18 °C, …

Modeling The Collagen Fibril Network Of Biological Tissues As A Nonlinearly Elastic Material Using A Continuous Volume Fraction Distribution Function, Reza Shirazi, Pasquale Vena, Robert L. Sah, Stephen M. Klisch

Mechanical Engineering

Despite distinct mechanical functions, biological soft tissues have a common microstructure in which a ground matrix is reinforced by a collagen fibril network. The microstructural properties of the collagen network contribute to continuum mechanical tissue properties that are strongly anisotropic with tensile-compressive asymmetry. In this study, a novel approach based on a continuous distribution of collagen fibril volume fractions is developed to model fibril reinforced soft tissues as nonlinearly elastic and anisotropic material. Compared with other approaches that use a normalized number of fibrils for the definition of the distribution function, this representation is based on a distribution parameter (i.e. …

Protective Effects Of Milk Phospholipids Against Uv Photodamage In Human Skin Equivalents, Zyra Achay

Master's Theses

The ultraviolet (UV) spectrum has been known to cause damage to skin in varying degrees. UVB radiation (290-320 nm) in particular, has been proven to be highly mutagenic and carcinogenic in many animal experiments compared to either UVA or UVC. The alarming rate of increase in skin cancer incidence has prompted many investigators to pursue other alternatives to sunscreens including changes in lifestyle habits and dietary consumption in order to boost our efforts in tackling this widespread disease. Previous studies employing confocal reflectance, MTT assay and histology suggest that milk phospholipids may possess protective properties against UVB-mediated damage but the …
