BIOREMEDIATION OF TRICHLOROETHENE AND HEXAVALENT CHROMIUM: A SITE-SPECIFIC CASE STUDY

Description

Trichloroethene (TCE) and hexavalent chromium [Cr(VI)] are toxic and carcinogenic contaminants found in drinking water resources across the United States. A series of Bench-scale treatability studies were conducted to evaluate

Trichloroethene (TCE) and hexavalent chromium [Cr(VI)] are toxic and carcinogenic contaminants found in drinking water resources across the United States. A series of Bench-scale treatability studies were conducted to evaluate the effectiveness of a consortium of facultative and strictly anaerobic bacteria, KB-1®, to remove TCE and Cr(VI) from a contaminated aquifer in San Diego. These series of treatability studies were also performed to prepare data and mature packed sediment columns for the deployment of the In Situ Microcosm Array (ISMA), a diagnostic device for determining optimal treatments for a contaminated aquifer, at this particular site. First, a control panel for the ISMA’s Injection Module (IM) was created in order to deliver nutrients to the columns. Then, a column treatability study was performed in order to produce columns with an established KB-1® consortium, so that all TCE in the column influent was converted to ethene by the time it had exited the column. Finally, a batch bottle treatability study was performed to determine KB-1®’s effectiveness at remediating both TCE and Cr(VI) from the San Diego ground-water samples. The results from the column study found that KB-1® was able to reduce TCE in mineral media. However, in the presence of site ground-water for the batch bottle study, KB-1® was only able to reduce Cr(VI) and no TCE dechlorination was observed. This result suggests that the dechlorinating culture cannot survive prolonged exposure to Cr(VI). Therefore, future work may involve repeating the batch bottle study with Cr(VI) removed from the groundwater prior to inoculation to determine if KB-1® is then able to dechlorinate TCE.

Increasing Understanding of the Value of Arts Programs in Education (K-12) In Partnership with the Arizona Commission on the Arts

Description

This project was undertaken for the purposes of exploring the feasibility of website development for arts education information. In partnership with the Arizona Commission on the Arts, ideas for website

This project was undertaken for the purposes of exploring the feasibility of website development for arts education information. In partnership with the Arizona Commission on the Arts, ideas for website design were collected. The original plan was to build a website that would be a "one-stop-shop" for educators to find arts education resources. Some resources deemed important to include on the website were: a search engine, calendar of events, curriculum ideas, discussion forum, feedback, ticketing, and financial support available. This website would make accessing arts education information easier, thus more appealing. It is understood that art is a fundamental part of education and it needs to be integrated into the public schools system, however, due to a lack of educational funding in Arizona it is important to bring outside organizations and resources into the education system. The following paper will examine how arts education is beneficial for children in grades K-12, what resources people want available on the website, what education administrators have to say about the website, and what aspects of the website would need to be included and addressed.

A Composition of Dance

Description

My intention with this project was multifaceted; my goal was to articulate in words and share through physical embodiment what dance means to me and how dance has helped shape me as an individual. In doing so, I delved into an exploration of defining dance and its role within my life and in society at large. Inspired by the black and white, silent film The Artist, I began pondering how important external elements such as music, lighting, and color are when choreographing work and furthermore sharing it with an audience. For most mainstream concert dance choreographers, these elements are an integral part of the artistic process and factor into the totality of a performance experience as a work comes into fruition. The title of my thesis, A Composition of Dance, is a play on words in my attempt to challenge my own notion of dance and investigate how one's senses and environment can influence one's perception of dance from both the performer and audience perspective.

DANCE AND THE SENSE OF TOUCH

Description

The goal of this study was to look at touch and dance from different views to gain a better perspective on the benefits of touch, mainly when used in dance

The goal of this study was to look at touch and dance from different views to gain a better perspective on the benefits of touch, mainly when used in dance and also perhaps in broader contexts. Part of this investigation also looked at the stigmatized view of touch in the American culture and in turn the lack of knowledge about, and comfort with touch in our society. A personal research component involved the creation of a solo reflecting about the question of why I connect with touch so intensely. The bulk of the study involved facilitating touch experiences in two introductory level dance classes for high school students. Daily journal entries were collected from each of the eighty students that focused on their personal experiences with touch in a series of six movement sessions. The study shows that bringing touch to the dance classroom has multiple benefits, including promoting a greater understanding and acceptance of the sense of touch, a positive impact on students' views about dance, and a break down of preconceived notions about the mind and the body.
