Water And Air Quality Performance Of A Reciprocating Biofilter Treating Dairy Wastewater, Seppi Matthew Henneman

Master's Theses

ABSTRACT

Water and Air Quality Performance of a Reciprocating

Biofilter Treating Dairy Wastewater

Seppi Matthew Henneman

Agricultural non-point source pollution is the leading water quality problem in surface water and the second leading problem in ground water in the US.  Among the contaminants, nutrients (such as nitrogen, phosphorus, potassium) can be transported from agricultural fields when cropland is not managed properly.  In California, dairy manure application to cropland has become tightly regulated with the goal of decreasing such nutrient pollution.  Dairies unable to balance their manure nutrient supply with cropland application area may benefit from a nitrogen removal technology.  One …

An Investigative Study Of Gurney Flaps On A Naca 0036 Airfoil, Gregory F. Altmann

Master's Theses

This project examined the effect of Gurney flaps on a 2D, 2-ft chord NACA 0036 airfoil in the Cal Poly 3’x4’ low speed wind tunnel at 25 m/s.  It also covered the numerical simulation of the experiment in computational fluid dynamics (CFD).  During the study, problems with the wind tunnel data were seen.  After a careful diagnosis, the problem was traced to dirty flow conditioners which were subsequently replaced.

Five Gurney flaps at 1, 2, 3, 4, and 5% of the chord were tested.  The Gurney flaps had the effect of eliminating the lift reversal effect and lowering the profile …

A Study Into The Use Of Microprocessor Relays For Motor Operated Valve (Mov) Electrical Protection In Nuclear Power Plants, James Andrew Tuccillo

Master's Theses

Motor Operated Valves (MOVs) are electro-mechanical components used to isolate, divert, or introduce fluid flow. The use of microprocessor relays for actuator motor electrical protection within nuclear power plants is the focus of this thesis and is implemented by providing a new and enhanced protection scheme that provides the adequate conservatism necessary to ensure valve operation while still maintaining electrical safety and continued operational availability. The comprehensive protection scheme is designed around an advanced microprocessor relay that has the ability to simulate the thermal overload conditions of a motor operating into a destructive thermal region. Through laboratory testing, the validity …

High-Resolution, Non-Contact Angular Measurement System For Psa/Rsa, Ronald D. Sloat

Master's Theses

A non-contact angular measurement system for Pitch Static Attitude (PSA) and Roll Static Attitude (RSA) of hard disk drive sliders is designed and built. Real-time sampling at over 15 KHz is achieved with accuracy of +/- 0.05 degrees over a range of approximately 2-3 degrees. Measuring the PSA and RSA is critical for hard drive manufacturers to control and improve the quality and reliability of hard drives. Although the hard drive industry is able to measure the PSA and RSA at the subassembly level at this time, there is no system available that is able to measure PSA/RSA at the …

Pcr Primers For The Detection Of Propane And Butane-Oxidizing Microorganisms, Brian Jeremy Chan

Master's Theses

In an increasingly energy-hungry world, our capacity to meet the heightened energy demands of the future has become a pressing matter. The most urgent of these concerns are tied to the accessibility of petroleum. Various experts have proselytized both the imminent arrival of peak oil production rates and the ensuing decline of those rates thereafter. And to that end, the development of novel and advanced oil exploration methodologies has become almost as important as finding the sources of oil themselves.

The soils above petroleum reservoirs play host to various communities of alkane- oxidizing bacteria that can utilize the natural gas …

Modern Leadership Compared To Historical Leadership Shown Biblically, Forrest Jones

Master's Theses

Modern Leadership Compared to Historical Leadership Shown Biblically

Forrest Jones

This thesis is a comparison between modern leadership and historical leadership.  Modern leadership has been differentiated from management since the early 1980’s.  Historical leadership is shown by Jesus Christ through the Bible, used as a historical text.  Historical leadership was found to have two separate tools used by Jesus Christ which would be useful additions to what leadership today is.  The first tool is submission to authority.  Most people in positions that would be considered leadership positions do not feel that they need to follow anyone else.  Often times they …

Growing Conflict: Agriculture, Innovation, And Immigration In San Luis Obispo County, 1837–1937, Douglas P. Jenzen

Master's Theses

The history of San Luis Obispo and its surrounding areas is complex. Agriculture, innovation, and immigration have all contributed to the formation of the region. The Spanish, Mexican, and early American periods established the framework successive waves of immigrants had to live within. Native Americans and immigrants from China, Portugal, Switzerland, Japan, the Philippines, and other regions of the United States have all toiled in the fields and contributed to America’s tables at various points throughout county history. Many contingencies determined the treatment of successive waves of immigrants. Growth and development are taking place at exponential rates on the very …

Losing The Colonies: How Differing Interpretations Of The British Constitution Caused The American Revolution, Brian M. Flint

Master's Theses

Faced with an economic crisis following the French and Indian War, the British Parliament, along with a young and inexperienced King George III changed its longstanding policy towards the North American colonies.  Prior to 1763, Parliament allowed the colonies to generally govern themselves.  After 1763, Parliament began to pass legislation aimed at increasing revenue received from the colonies.  As the colonies protested these new taxes on constitutional grounds Parliament began a process of implementing and repealing different attempts at controlling the economic system in the colonies.  Due to differing interpretations of the British Constitution regarding Parliament's authority over the colonies, …

WebIDE is a new web-based development environment for entry-level programmers with two primary goals: minimize tool barriers to writing computer programs and introduce software engineering best practices early in a student's educational career. Currently, WebIDE focuses on Test-Driven Learning (TDL) by using small iterative examples and introducing lock-step labs, which prevent the student from moving forward until they finish the current step. An initial set of labs and evaluators were created as examples of how to use WebIDE and were used in a pilot study in a CS0 course where students were split into two groups, one that used WebIDE …

Congrats: A Configurable Granular Trust Scheme For Effective Seller Selection In An E-Marketplace, Ogbonnaya Boniface Akpa

Master's Theses

Problem. The e-marketplace of today, with millions of buyers and sellers who never get to meet face to face, is susceptible to the presence of dishonest and fraudulent participants, prowling on unsuspecting trading partners to cheat in transactions, thereby increasing their profit to the detriment of their victims. There is also the multiplicity of goods and services with varying prices and quality, offered by a mix of honest and dishonest vendors. In order to participate in trade without incurring substantial loss, participants rely on intelligent agents using a trust evaluation scheme for partner selection. Making good deals thus depends on …

The Highest Good And The Best Activity: Aristotle On The Well-Lived Life, Philip William Bauchan

Master's Theses

The question of how Aristotle characterizes eudaimonia, or living-well, in the Nicomachean Ethics has long been a contentious issue amongst Aristotelian scholars. The secondary literature has been roughly divided between inclusivist readers, who argue that Aristotle designates both theoria, or contemplation, and the practical virtues, and exclusivist readers, who argue that Aristotle singles out theoria alone. This thesis seeks to forge a middle ground between these two perspectives by focusing on the central claim of Book I that the eudaimonia is virtuous activity. Reading Book X in light of Book I's claim then allows one to show that both the …

Stream Restoration In A Post-Agricultural System: Indirect Effects On Density And Secondary Production Of Aquatic Insects, Lyle Stanley Dandridge Jr

Master's Theses

Restoration of stream habitats, with the goal of increasing biodiversity through increasing habitat heterogeneity, has been an ongoing trend in recent decades. Current investigations suggest most of those projects fail to significantly influence ecological structure and function when evaluated in light of their affect on species richness. In order to assess the <&ldquo>success of restoration on a prairie stream in northern Illinois traditional metrics such as community composition and density were examined in addition to macroinvertebrate secondary production. Restoration of Nippersink Creek, McHenry County, Illinois was completed in 2000 and this study was conducted 8 years post-restoration. Benthic samples were …

Who Plays? Who Pays?: A Chicago Case Study Of Racism, The Lottery, And Education, Kasey Henricks

Master's Theses

Many Chicagoans are getting shortchanged, particularly when it comes to the money-exchange process between the Illinois Lottery (IL) and the Illinois State Board of Education (ISBE). In Illinois, a significant portion of lottery-generated revenues is earmarked to finance public education. Because these revenues are not generated equally across Chicago, some communities contribute more to education via the lottery than others. When these revenues are distributed in such a way that transfers money from one community to another, one community's fiscal gain comes at another's expense. So the question stands: Who plays and who pays? To answer this question, I measure …

Systemic Barriers To The Implementation Of International Education Policy: A Comparative Analysis Of The United States And France, Zephranie Buetow

Master's Theses

This thesis will argue that systemic barriers hinder the implementation of international education laws designed to eliminate inequality. Discriminatory practices are frequently embedded in national views. These views present themselves in legislative choices despite the form of government. Further, embedded beliefs influence a nation's commitment or resistance to international human rights instruments. An analysis of state commitment and resistance to international education laws will serve as a guide for identifying and understanding the legislative barriers preventing the enactment of meaningful international education policy.

Analyses on this subject have been reductionist in nature. They have failed to sufficiently consider all relevant …

Effects Of Water Conservation On Evapotranspiration In Las Vegas, Nevada, Joseph Belli

Master's Theses

Las Vegas, Nevada, is a rapidly growing arid city that is experiencing significant challenges in water consumption. Most of the water is used outdoors, precluding recycling and reuse of water. With a large increase in population, the Southern Nevada Water Authority created the Water Smart Landscape Program to limit outdoor water usage. This study used remote sensing images and techniques to examine how much water was lost to the atmosphere through evapotranspiration (ET) in the Las Vegas metropolitan region from 1999 to 2009. The results showed that both extreme weather conditions and water policy influence ET rates.

Water And Power: Agricultural Intensification In Windward North Kohala, Hawai'i Island, Christopher Ian Avery

Master's Theses

This thesis examines the processes of agricultural intensification in the eastern gulch region of windward North Kohala district, Hawai`i Island. The intensification of agricultural production was essential for Hawai`i's transition from a collection of loose tribelets into an archaic state. To meet the growing demands of social paramounts, ancient farmers in North Kohala innovated novel technologies to improve their capacity to produce surpluses. In windward North Kohala, the chief innovation was intricate irrigation systems that transferred water from the region's gulch beds to the adjacent elevated tablelands, first identified by the Hawai`i Archaeological Research Project in 2008 and further explored …

For All Time: An Examination Of Romantic Love Through Curse Tablets, Alicia Deadrick

Master's Theses

This thesis analyzes the Greco-Roman amatory defixiones, or curse tablets, and binding spells from the fourth century BCE to the fourth century CE in order to investigate the existence of romantic love in the Mediterranean Basin. Binding spells provide a unique opportunity for cultural analysis, for they were popular with all levels of society, both genders and all sexualities. Three categories of amatory spells prevalent in ancient society (agoge, separation, and philia) undergo examination to establish romantic love as a sentiment separate from eros and philia and in opposition of the currently prevailing relationship theory of …

Synthesis Of Hybrid Inositol Glycan Analogues, Smita Fulzele

Master's Theses

Inositol glycans (IGs) are small oligosaccharides exhibiting insulin-like metabolic activities in insulin-sensitive cells. The signal transduction pathways activated by IGs in these cells are still under study, but it is known that there is cross talk between the IG-signaling pathway and the insulin-signaling pathway downstream of the insulin receptor. Therefore, IGs may have potential for use in the treatment of type II diabetes mellitus. However, natural IGs are heterogeneous and difficult to isolate. Hence, synthetic IGs and their analogues have been chemically synthesized and evaluated for insulin-mimetic properties by various research groups. Unfortunately, the most biologically active IG analogues are …

Teaching And Learning Of Proof In The College Curriculum, Maja Derek

Master's Theses

Mathematical proof, as an essential part of mathematics,

is as difficult to learn as it is to teach. In this thesis, we

provide a short overview of how mathematical proof is understood

by students in K-16. Furthermore, we answer questions about

mistakes students usually make in the transition period from high

school to college in understanding mathematics and mathematical

proof. Through a case study, we learned that deduction mistakes

characteristic for early mathematical education, such as arguing

from an example, can be abandoned very easily as students begin to

understand the inadequacy of one, or finitely many, examples when

arguing …

The Impact Of Instructor-Provided Lecture Notes And Learning Interventions On Student Note Taking And Generative Processing, Karen Lynn Gee

Master's Theses

While the review (memory storage) function of student lecture notes is well established, research findings on the learning benefits of actually taking these notes (memory encoding) has been mixed. The current study provided all students with a complete content outline for use in studying, so the effects of taking personal notes could be isolated. Students who received the complete outline before the lecture took significantly fewer personal notes than did students who received the outline after lecture, though both groups performed similarly on factual and application tests. Students who were directed to generate novel examples for each topic also performed …

Can't Sing, Can't Dance, Can't Draw: How Leisure Constraints And Negotiations Impact Midlife Women's Participation In The Creative Arts, Debra Ann Ullmann

Master's Theses

This qualitative, exploratory study involving semi-structured interviews of 12 midlife women, ages 45 to 65, sought insight into how intrapersonal, interpersonal, and structural constraints, constraint negotiations, and motivations facilitate or impede midlife women's active participation in the creative arts. The data were analyzed within a socio-cultural context using grounded theory. Findings indicate that dynamic interactions involving social comparison result in judgment by others, of others, and of self. This spiraling effect is often initiated in childhood or adolescence. Once a woman internalizes the notion that she "can't sing, can't dance, can"t draw," there is seldom any attempt to negotiate constraints …

Non-Homogeneous Hybrid Rocket Fuel For Enhanced Regression Rates Utilizing Partial Entrainment, Kenny Michael Boronowsky

Master's Theses

A concept was developed and tested to enhance the performance and regression rate of hydroxyl terminated polybutadiene (HTPB), a commonly used hybrid rocket fuel. By adding small nodules of paraffin into the HTPB fuel, a non-homogeneous mixture was created resulting in increased regression rates. The goal was to develop a fuel with a simplified single core geometry and a tailorable regression rate. The new fuel would benefit from the structural stability of HTPB yet not suffer from the large void fraction representative of typical HTPB core geometries.

Regression rates were compared between traditional HTPB single core grains, 85% HTPB mixed …
