In order to help inform the applicability of carbon nanotube networks for use as field effect transistors or as biosensors, we have run computer simulations in order to characterize the electrical properties of these networks, and specifically, how the resistance of these networks scales with the channel length for various amounts of metallic wires present in the networks. We find a trend that as the channel length increases, the resistance of the network increases as well. In addition, as the probability of metallic wires present in the network increases, the scaling factor of the resistance, m, increases at a larger constant rate with increasing channel length.

Non-native species come to Humboldt county when small patches are washed up on beaches, hitch rides on ships and cars, or escape from someone's garden. Some of these species are considered invasive, and rapidly take over the landscape. Once they establish, they starve native species of resources like light and water, and out-compete them for surface area on the ground. They also harm native animals by replacing their food sources, harming them, or changing the landscape in which they live. Volunteering with the Invasive Plant Removal Team at Sue-Meg State Park, I had firsthand experience examining and removing these species across Humboldt County.

According to the National Institute of Mental Health (NIMH), as much as 10 to 15 percent of American teenagers experience symptoms of depression at any one given time (2014). Research has shown that mindfulness methods and art therapy methods have both proven themselves useful in treating this disease, but there is little research that has delved into the possible benefits of combining these two methodologies. This project combines these two forms of coping skills into one curriculum for use in school or therapeutic settings aimed at helping adolescents find outlets for dealing with their depression. That's the goal of this project: the creation of a mindfulness and art therapy guidebook.

An organic photovoltaic (OPV) is a polymeric or small molecule device that accepts photons and generates a current. Donor-acceptor molecules are used to create a heterojunction where an electronic environment dissociates excitons, which are bound excited electron-hole pairs. Charge dissociation is facilitated at the heterojunction by the interaction of an exciton on the donor molecule with the electronic configuration of the acceptor molecule. Thiophene derivatives have proven to be promising candidates for high efficiency donor molecules. Rational design and attempted synthesis of bis(diaryl)-thienothiadiazole compounds with pyridyl and pyrimidyl groups are reported.

Having a part-time job is a necessary part of life for many college students. It is possible that working an on-campus part-time job can have a positive effect on student retention, especially for racially minoritized students. This research investigated if there is a correlation between persistence to graduation and on-campus part-time employment for racially minoritized students by examining sense of community, self-reliance, and sense of self. Additionally, four professional academic advisors were interviewed about advising students who are working while in college.

Study of a powerlifting power to increase 1RM on the bench press.

In this study, we investigated the influence of thinning and prescribed fire on tree growth responses to multi-year drought conditions in the dry forests of Whiskeytown National Recreation Area in northern California. Specific questions include: 1) Do fuel reduction treatments influence forest resistance to drought stress? 2) What individual tree-level and site-level factors (i.e. size, crown height, competition, pre-disturbance tree growth) influence tree growth responses? 3) Do tree growth responses change over years of successive drought stress?

Thomas Fire, drew immediate attention from all across California on December 4, 2017 during a time of year with higher levels of precipitation. Roughly 281,000 acres of land was engulfed by the extent of the wildfire outbreak where typically the native chaparral are known to thrive despite chaparral schrubland have typically evolved to remain fire tolerant. This study was able to determine a variety in vegetation change, further tests involving supervised classification and collection of field data (ground trothing) would provide more information giving way to further suggestions as to what indicators contributed the most to California’s worst wild fire outbreak.

The presentation will be on various topics researched for the county supervisor, ie local gun control laws, biodegradable shotgun wads, California granges, and the research and dissemination process of gathering information and presenting the information to the county supervisor. Each topic will receive time and space, but the presentation will focus on the internship instead of the topics.

Pill bugs roll into a ball for more reasons than to protect themselves! They may also be conserving water, thermoregulating, or it may all be up to individual boldness. My research investigated whether soil moisture would affect the amount of time it took for pill bugs to unroll. I found that there was no correlation between sex, length, soil moisture, and the amount of time they spent rolled up. However, there was a great variation among individuals.
