We present the first survey of extremely high velocity outflows (EHVO) in quasars from the Sloan Digital Sky Survey data release nine quasar catalog (SDSS DR9Q). Our survey draws from the 87,822 spectral targets in DR9Q. EHVO candidates were identified by measurement of one of the transitions due to absorption in carbon ion (C-IV), which appear in the spectrum as broad absorption features. Spectrum analysis was carried out by python codes developed by our group with results confirmed by visual inspection. The presented survey is composed of 45 quasars EHVO ranging in velocity from ~50,000 to 30,000 km/s. Our survey will be made available online as a publicly accessible database.
Sustainability in Mental Health
Meghan Stanton, Social Work Graduate Student
- AngelaBorgeSocial WorkGraduate Student
Our community project has been multifaceted as there are several issues impacting Semper Virens. We have been focusing on identifying ways to utilize the physical environment of Semper Virens in more therapeutic ways that would also be more welcoming and nurturing for the clients as well as more positive for the staff. We have simultaneously been developing workbooks of complementary exercises and activities aimed at improving mental health, wellness, and selfcare. The workbooks contain a variety of approaches including one specifically adapted for Native Americans.
Sustainable Learning For Student Success

Rising textbook costs and the shift to the subscription model licensing has negatively impacted student success across the nation. The CSU Affordable Learning Solutions (AL$) program was created to support CSU campus initiatives for implementing strategies to reduce the cost of materials and foster more equitable student access to required course materials. This poster highlights the results of our outreach since the Cal Poly Humboldt Library joined the AL$ program. Our department has saved Cal Poly Humboldt students over $1M in course materials costs. Our primary methods are researching free OER material for possible adoption and supporting Cal Poly Humboldt faculty who publish new content.
Switching to Electric Cars , and the Efficiency of Allocating Charging Stations

For environmental and economic reasons, there is a global interest in reducing the use of fossil fuels, including gasoline for cars. Whether motivated by the environment or by the economics, consumers are starting to switch to electric vehicles. Several countries are seeing early signs of the potential for rapid growth in the adoption of electric vehicles. In the US and other countries, the release of the more affordable all-electric Tesla Model 3 has resulted in record numbers of pre-orders and long wait lists. Our group set out to find an optimal allocation of electric charging stations in the U.S and South Korea by creating a math model of the number of stations per region.

Lead is a particularly problematic environmental contaminant. The peptide sequence GGGTNTLSNNGGG has an affinity for binding lead particles. Utilizing solid phase reaction chemistry the peptoid analog was synthesized. The resin bound peptoid has been evaluated for lead binding affinity using Flame Atomic Absorption Spectrophotometry. Initial results show a 27:1 lead to peptoid binding with an average 14% lead decrease in the presence of 1.31× 10-5 per mole of the peptoid. Treatment of peptoid bound lead with hydrochloric acid resulted in release of lead indicating the recyclability of this peptoid modified resin.
Synthesis of Bis(diaryl)thienothiadiazole Compounds with Pyridyl and Pyrimidyl Groups For Use in Organic Photovoltaic Cells
- Gregory PitchChemistry/ Environmental ScienceUndergraduate Student
- Kiefer Bell-WilsonChemistryUndergraduate Student
- Micah OjedaChemistryUndergraduate Student
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.
Tactics to Prevent Sexual Assault in Athletics
- Payton belleCommunicationsUndergraduate Student
This poster will discuss sexual assault that happens in all levels of athletics and how we can prevent this from happening. By taking time to educate young athletes about what sexual assault is, consent and what it looks like, so they will know how to prevent and respond to sexual assault. Hopefully by educating young athletes, they will know and change the future to make athletics more safe for everybody.
Tailoring the Learning Environment: Generation Z
- Kai CooperInternational StudiesUndergraduate Student
By addressing the needs of Generation Z students in the classroom, we are able to tailor the learning environment to the generation. The ineffectiveness of the traditional teaching pedagogy shows the need to adapt the classroom. As a classroom assistant in a service-learning class, I was able to see how communication in the classroom plus reflection creates community, and awareness of community. By proposing a dynamic learning environment such as one with service-learning, one is able to shape the way the classroom interacts and engages with its students to address their changing learning style. We need to ask the question of how can we engage students in an adapting and changing world.
Talking to Yourself: Let's Talk About Intrapersonal Communication!
- Kasandra Marguerite ColwellCommunicationUndergraduate Student
Intrapersonal communication consists of the internal communication that occurs within each of us, where we send and receive messages within ourselves. Intrapersonal communication highly impacts the more well-known concept of interpersonal communication, which occurs between two or more people. Yet, intrapersonal communication isn't listed as an interest group under the National Communication Association! Consequently, student exposure to this concept is often limited to a small section in introduction to communication courses. In this presentation, I argue that California Polytechnic Humboldt should offer a course in intrapersonal communication and I share a potential syllabus I've created.
Taphonomic Bone Shrinkage: A Study on the Effects of Wet and Dry Climates on Postmortem Bone Shrinkage

- Thomas MathewsAnthropologyUndergraduate Student
In forensics, stature estimation is a key component of the assessment of skeletal remains. Estimating stature involves extrapolation from the length of long bones. Previous research has indicated environment can result in postmortem shrinkage of bone, and therefore affect stature estimates. This research project examines the extent of bone shrinkage that occurs when bones are exposed to the elements, dried out in a fume hood and submerged underwater. Measurements of bone length were taken at regular intervals. Preliminary analysis indicates a relationship between precipitation and postmortem shrinkage. This study has the potential to aid in assessing the accuracy of stature calculations.
