Poly(N-Isopropylacrylamide) Hydrogels For Storage And Delivery Of Reagents To Paper-Based Analytical Devices, Haydn T. Mitchell, Spencer Schultz, Philip Costanzo, Andres W. Martinez
Chemistry and Biochemistry
The thermally responsive hydrogel N,N'-methylenebisacrylamide-cross-linked poly(N-isopropylacrylamide) (PNIPAM) was developed and evaluated as a reagent storage and delivery system for microfluidic paper-based analytical devices (microPADs). PNIPAM was shown to successfully deliver multiple solutions to microPADs in specific sequences or simultaneously in laminar-flow configuration and was found to be suitable for delivering four classes of reagents to the devices: Small molecules, enzymes, antibodies and DNA. PNIPAM was also able to successfully deliver a series of standard glucose solutions to microPADs equipped to perform a colorimetric glucose assay. The results of these tests were used to produce an external calibration …

The Pioneer Of Santa Rosa Island, Andrea Martinez, Michael Perez, Kathryn Mceachern, Sarah Chaney, Ken Niessen
STAR Program Research Presentations
Santa Rosa Island which is part of the Channel Islands in California has a ranching history that goes as far back as the year 1843. While rich in history, the island is no longer “rich” in native plant populations due to the sheep, cattle and other livestock that once occupied the island. As a result of these grazers that the ranchers livelihood depended on, a great disturbance in the native plant population took place. It is up to plants such as Baccharis pilularis, commonly known as Coyote brush, to assist these endangered and threatened plants to once again flourish …

Drone technology has skyrocketed over the past decade driving costs down and the number of potential applications up, one being agricultural crop monitoring. Normalized Difference Vegetation Index (NDVI) is an imaging technique used to visualize near infrared light, which happens to be a very good indicator of plant health and productivity. This project aims to explore the potential of Unmanned Aerial Vehicles (UAV’s) using NDVI imaging for crop monitoring and assess the feasibility of the process by developing a UAV with a NDVI camera to create NDVI maps from the aerial crop images. These maps will be cross referenced with …
A Lego® Brewster Angle Microscope For Quantitative Monolayer Film Analysis, Nicholas Benz
A Lego® Brewster Angle Microscope For Quantitative Monolayer Film Analysis, Nicholas Benz
Physics
In order to study single-molecule thick films and their phase behavior we built a Brewster Angle Microscope (BAM). BAM’s are inherently expensive due to their accuracy and precision. We built a fully functional BAM using Lego® Mindstorm® kits for the fraction of the price of a commercial BAM. And by utilizing the 10µm patented Lego® tolerance, comparable accuracy was attained. The BAM was mounted to a Langmuir-trough and will be used for laboratory experiments for optics and physical chemistry along with research on lung surfactant and on liquid crystals.

Traversing Swanton Road, 20th Ed., James A. West
Academic, Government & Associated Organizational Research Resources
Situated at the northwest end of Santa Cruz County and occupying circa 30 square miles of sharply contrasted terrain, the Scott Creek Watershed concentrates within its geomorphological boundaries, at least 10-12% of California's flora, both native and introduced. Paradoxically, the use/abuse that the watershed has sustained over the past 140+ years, has not necessarily diminished the biodiversity and perhaps parallels the naturally disruptive but biologically energizing processes (fire, flooding, landslides and erosion), which have also been historically documented for the area for +60 years. This is an early edition of an extensive document by James A. West. Please visit the …

On The Dynamics Of Chronic Myelogenous Leukemia, The!Immune Response, And Multiple Drugs, John Shamshoian, David Kato, Caleb Miller
Baker/Koob Endowments Awarded Projects
Chronic myelogenous leukemia (CML) is a cancer that begins in the bone marrow and spreads to the bloodstream and other organs if left uncontrolled. Although most patients undergo some sort of remission with the standard drug imatinib, patients will inevitably relapse [1]. Many CML researchers utilize mathematical models to understand leukemia and immune-‐ response interaction and to create novel methods of treatment. We adopt a time-‐delay differential equation model, used by Michor et. al [2], which incorporates biologically significant parameters and leukemia –T-‐cell interactions. Inconveniently, the model is a system of nine nonlinear differential equations encompassing over two dozen parameters. …

Application Of Pyroprinting For Source Tracking Of E. Coli In Pennington Creek, Charles Moritz, Dillon Shapiro, Christopher Pann
Application Of Pyroprinting For Source Tracking Of E. Coli In Pennington Creek, Charles Moritz, Dillon Shapiro, Christopher Pann
Baker/Koob Endowments Awarded Projects
The goal of this project is to determine the source of fecal contamination in Pennington Creek. Dangerously high numbers of E. coli were recorded in the creek by the Morro Bay National Estuary Program (MBNEP) over the last 10 years. This is of particular concern because the creek runs directly through an outdoor school for K-12 education. One potential source of the contamination is the cattle in fields on either side of the creek for several miles, though they are supposedly kept out by fences. Another possibility is local wildlife—specifically wild turkeys, which roam around in flocks of over 100 …

Headstart Nursery: Rooted In Quality, Luis Alonzo, Michael Joyce, Clinton Loomis, Doug Kaplan
Headstart Nursery: Rooted In Quality, Luis Alonzo, Michael Joyce, Clinton Loomis, Doug Kaplan
Case Studies in Agribusiness
Growers can more efficiently use their land if they grow from transplants than from seed. Headstart Nursery started in 1979 to supply Christopher Ranch, well-known for their garlic products, with bell pepper transplants. Since then, Headstart expanded their transplant line to other Salinas Valley crops and even flowers. Transplants are labor intensive; Headstart has been innovative with their human resource management policies and practices.

Characterization Of Pressure-Driven And Electro-Kinetically Driven Flow In A Micro-Fluidic Chip Using Particle Imaging Velocimetry, Alexis Weckel
Characterization Of Pressure-Driven And Electro-Kinetically Driven Flow In A Micro-Fluidic Chip Using Particle Imaging Velocimetry, Alexis Weckel
Master's Theses
The flow profiles of pressure-driven and electro-kinetic driven flows were compared for a microfluidic chip. It was found that the pressure-driven flow had a parabolic profile while the electro-kinetic flow had a plug shaped flow profile. The measured velocities were similar to those determined by the Poiseuille flow model and the Helmholtz-Smoltchowski equation. Flow uniformity is very important for control in microfluidic mixers. Parabolic flow profiles lead to inconsistent reactions while the more uniform plug shape flow allow for a more steady reaction across the channel. Previous work had been performed to measure the flow of a solution of fluorescent …

Effect Of Heat Treatment On The Mechanical Properties In Natural Bamboo, Austin Levy, Mackenzie Kirkpatrick
Effect Of Heat Treatment On The Mechanical Properties In Natural Bamboo, Austin Levy, Mackenzie Kirkpatrick
Materials Engineering
Previous studies have shown that heat treatments have the ability to improve mechanical strength and stiffness in hardwood species. Compared to structural hardwoods, bamboo is a more sustainable and globally viable renewable resource. Therefore, Bambusoides vivax (timber bamboo) culms were fabricated into flat, rectangular cross-section samples with varying cellulose content to be heat treated and tested for mechanical properties. All samples were heat treated (HT) twice. The first HT was a normalization of all samples at 103 +/- 3 °C. The second HT was performed at various times and temperatures ranging from 130°C to 170°C for 0.5 to 3 hours. …

The Pacific Crest Trail is a 2,600 mile area that begins at the border of San Diego and Mexico and finishes near the Washington and Canadian border. Cheryl Strayed wrote her memoir about her journey along this trail in 1995 at the age of 26. Her book was then made into a motion picture and released on December 25th, 2015. The director, Jean-Marc Vallee, was suggesting the idea that the Pacific Crest Trail was a very effective psychological therapeutic tool for grieving the loss of a parent while discovering one’s true authentic self. The traditional western methods of …
Investigating The Cause Of Unique Mechanical Behavior In Platinum Alloy Guidewire Tips, Evan Borgeson, Alfred Rosen
Investigating The Cause Of Unique Mechanical Behavior In Platinum Alloy Guidewire Tips, Evan Borgeson, Alfred Rosen
Materials Engineering
The platinum alloy used by Abbott Vascular in guidewire tips exhibits a yielding behavior characterized by an abrupt transition from elastic to plastic zones and high ductility. This yielding behavior was hypothesized to be a result of one of three structural phenomena: ordering, solute strain aging, or interstitial strain aging. To test for these strengthening mechanisms in the wire, X-ray diffraction analysis, heat treatments, and tensile testing were completed. The wire has a diameter of 0.0025 inches and was supplied in two forms, the final stress relieved state, and as-drawn from the production line. Heat treatments were performed at 130 …
