Taxonomy, Biogeography And Pest Status Of Marmara Sp. In Northern Mexico And California Citrus Production, Paul Semet

Master's Theses

A novel lepidopteran sex pheromone lure which was thought to be species-specific to the citrus pest Marmara gulosa (Lepidoptera: Gracillariidae) Guillén (McElfresh et al. 2009) has attracted male moths exhibiting two distinct morphologies. The morphological features examined were the sclerotized parts that make up the male genitalia; which include the valvular lobes, costal lobes, cucullar lobes, and the aedeagus. The sclerotized parts were methodically dissected and mounted on microscope slides. Digital images captured of the slide-mounted specimens proved to be inconsistent with the illustrations provided in the original Marmara gulosa species description (Guillén et al. 2001).

The morphologies of all …

Electrical Engineering

The integration of the UAV pirating system with the SilenTrack video tracking system will allow the combined system to automatically identify and track a suspicious air vehicle visually as well as identify and decode the RF control signal. Once a threat has been identified, the system will execute an algorithm to associate each control channel with the corresponding flight control surface. Once the control channels have been decoded the user can use a hand held radio controller to maneuver the drone which is now under their command.

Development Towards A Protocol To Test For The Creation Of A “Diabetic” Environment In A Blood Vessel Mimic, Kaitlyn Kirk, Development Towards A Protocol To Test For The Creation Of A “Diabetic” Environment In A Blood Vessel Mimic

Biomedical Engineering

Diabetes mellitus affects a huge proportion of people; about 6% of the population in the US had diabetes in 2007 (16). Diabetes promotes dyslipidemia, an imbalance in the circulating levels of lipids and lipoproteins, and diabetes is one of the leading risk factors for coronary artery and peripheral vascular diseases (11, 51, 52).  There are two types of diabetes; type 1 diabetes accounts for about 10% of diagnosed cases and type 2 accounts for about 90% (11).  Diabetic patients react differently to stents and there is a great need to enhance the treatment.  The goal of this project was, and …

Environmental Variables Influencing The Severity Of Pierce's Disease In California Grapevines, Christopher James Boisseranc

Master's Theses

This project was designed to correlate environmental variables with the development of Pierce’s Disease (PD), an infection caused by the gram negative bacterium Xylella fastidiosa (Xf), in grapes (Hopkins et al. 2002). PD is one of the most difficult crop pathogens to manage because it is vectored by insects and its continued presence in the vine is usually fatal. PD is influenced by the interaction of host, disease and vector, and probably many other environmental variables. The general objective was to study and identify the most important variables involved in the expression of Pierce’s Disease.

Over a two year period, …

Labeling Disability In America, Nicole C. Webster

Communication Studies

This paper explores how labels are used in regard to disabilities in the dominant American culture. Ignorance is the link between language and discrimination and inequalities for people with disabilities. Americans can be educated through disability studies so as to become capable of empathizing with and enabling, rather than disabling, their compatriots.

Global Warming: Myths & Realities, Dennis Jaynes

Social Sciences

The topic of Global Warming has been surrounded with controversy since it was first proposed. From evidence that has come from years of studies, a majority of the world’s governments and scientists are in agreement that the Earth’s global temperatures are warming. However, there are others who are skeptical of the science; they spread their message by trying to discredit the scientists or have even gone as far as to cover it up. The intent of this paper is to examine the myths and compare them side by side with the latest scientific data to determine what is real and …

Horsing Around? Hippotherapy As A Context For Speech Therapy, Kara Schricker

Psychology and Child Development

Language and communication are essential to our daily lives. With it we are able to express our wants and needs without frustration, without it we would not be able to effortlessly engage in the communication that is so essential to our daily lives. Children typically follow a pattern of development that allows them to develop language without delay. Interferences can arise that delay language development including: articulation disorders, fluency disorders, dysphagia, hearing impairment, cleft palate, or cognitive impairment. Each of these interferences has a unique cause and also a unique effect on children. A variety of therapies are available that …

The Influence Of Music On The Development Of Children, Theresa Riforgiate, Christopher Chau

Psychology and Child Development

Listening to classical music, like Mozart, is wonderful way to expand one's musical taste. Contrary to popular beliefs, however, this passive engagement with music does not make your child smarter. However, research demonstrates that active participation in music and music instruction help develop memory, perception, language, vocabulary, spoken skills, and reading skills. In order to disseminate these findings, we compiled a list of different opportunities around San Luis Obispo for children's active participation in music. Our goal is to provide parents with a resource to help them facilitate their children's involvement in music.

Exact Solutions For Wind-Driven Coastal Upwelling And Downwelling Over Sloping Bathymetry, Dana Lynn Duke, Paul Derek Sinz

Mathematics

The dynamics of wind-driven coastal upwelling and downwelling are studied using a simplified dynamical model. Exact solutions are examined as a function of time and over a family of sloping bathymetries. Assumptions in the two-dimensional model include a frictionless ocean interior below the surface Ekman layer, and no alongshore dependence of the variables; however, dependence in the cross-shore and vertical directions is retained. Additionally, density and alongshore momentum are advected by the cross-shore velocity in order to maintain thermal wind. The time-dependent initial-value problem is solved with constant initial stratification and no initial alongshore flow. An alongshore pressure gradient is …
