Due to the environmental problems caused by global warming, it has become necessary to reduce greenhouse gas emissions across the planet. Biofuels, such as ethanol, have proven to release cleaner emissions when combusted. However, large scale production of these alcohols is uneconomical and inefficient due to limitations in standard separation processes, the most common being distillation. Pervaporation is a novel separation technique that utilizes a specialized membrane to separate multicomponent solutions. In this research project, pervaporation utilizing ZIF-71/PDMS mixed matrix membranes are investigated to see their ability to recover ethanol from an ethanol/aqueous separation. Membranes with varying nanoparticle concentrations were created and their performances were analyzed. While the final results indicate that no correlation exists between nanoparticle weight percentage and selectivity, this technology is still a promising avenue for biofuel production. Future work will be conducted to improve this existing process and enhance membrane selectivity.

This project, which consists of a review article and an applied creative project, proposes mirror neurons as being a physiological mechanism for motor imagery. The review article highlights similarities between motor imagery research and research on mirror neurons. The research is roughly divided into three types of studies: neuroimaging studies, transcranial magnetic stimulation (TMS) and electromyography (EMG) studies, and electroencephalography (EEG) studies. The review also discusses the associative hypothesis of mirror neuron origin as support for the hypothesis and concludes with an assessment of conflicting research and the limitations of the hypothesis. The applied creative project is an instructional brochure, aimed at anyone who teaches motor skills, such as dance teachers or sports coaches. The brochure takes the academic content of the review and presents it in a visually pleasing, reader-friendly fashion in an effort to educate the intended audience and make the research more accessible. The brochure also prescribes research-based suggestions for how to use motor imagery during teaching sessions and how to get the best benefits from it.

The goal of this research project is to create a mixed matrix membrane that can withstand very acidic environments but still be used to purify water. The ultimate goal of this membrane is to be used to purify urine both here on Earth and in space. The membrane would be able to withstand these harsh conditions due the incorporation of a resilient impermeable polymer layer that will be cast above the lower hydrophilic layer. Nanoparticles called zeolites will act as a water selective pathway through this impermeable layer and allow water to flow through the membrane. This membrane will be made using a variety of methods and polymers to determine both the cheapest and most effective way of creating this chemical resistant membrane. If this research is successful, many more water sources can be tapped since the membranes will be able to withstand hard conditions. This document is primarily focused on our progress on the development of a highly permeable polymer-zeolite film that makes up the bottom layer of the membrane. Multiple types of casting methods were investigated and it was determined that spin coating at 4000 rpm was the most effective. Based on a literature review, we selected silicalite-1 zeolites as the water-selective nanoparticle component dispersed in a casting solution of polyacrylonitrile in N-methylpyrrolidinone to comprise this hydrophilic layer. We varied the casting conditions of several simple solution-casting methods to produce thin films on the porous substrate with optimal film properties for our membrane design. We then cast this solution on other types of support materials that are more flexible and inexpensive to determine which combination resulted in the thinnest and most permeable film.

Introduction/Purpose: This paper describes the process of the community needs assessment phase of program implementation for the Student Health Outreach for Wellness (SHOW) clinic. Homeless individuals are more likely (than non homeless individuals) to experience serious illness, depression and mental illness. Access to health care has been identified as a barrier to receiving appropriate health care to manage the diseases and conditions clients may have. SHOW's vision is to operate on Saturdays utilizing Health Care for the Homeless (HCH) to offer extended primary health care hours, along with offering health promotion programming to address the biopsychosocial components of their health. Ultimately, this aims to reduce the homeless population's need to visit emergency room departments for non- urgent, primary care visits. Methods: To validate the need for this clinic's operation of programming and health services, a community needs assessment was conducted to collect data about the population's current health status. Forty-three people (n=43) ages 20-76 (M = 44.87) were surveyed by a trained research team using interview questionnaires. Results: The results show a prevalence of self\u2014reported physical and behavioral conditions, and support that this population would benefit from extended hours of care. Mental and behavioral health conditions are the most prevalent conditions (with the highest rates of depression (41.86%) and anxiety disorder (32.56%)), followed by the common cold (23.36%) and back pain (16.28%). The average reported emergency department (ED) visits within the past six months was 1.18 times. Almost everyone surveyed would visit a free medical clinic on the Human Services Campus (HSC) staffed by health staff and health professional students on the weekends (93.18%). Conclusion: Overall, the community needs assessment conducted for SHOW supports the need for weekend access to health care facilities and an interest in health programming for this population.

The scarcity of fresh water worldwide has necessitated improved technology for desalinating sea water. Reverse osmosis membranes are currently limited by their inclination for fouling, in which a layer forms on the surface of the membrane and impedes water flux. This yields shortened membrane lifespan and increased energy costs. Current technology uses interfacially polymerized polyamide thin film composite membranes, which form nodules, leaves, and other structures that lead to rough film surfaces and may contribute to fouling propensity. In this study, polyamide latex was designed in order to cast a smoother membrane with comparable performance. Polyamide latex particles were formed using a modified procedure based on Lind et. al [10] and characterized for sphericity using scanning electromagnetic microscopy (SEM).

Creative adventurers are a modern artistic subculture defined by aesthetic individualism and rugged outdoor practicality. Contemporary photographers and videographers who live an active outdoor lifestyle place significant demands on their shoes and feet wherever they work. As a result of the increasing growth of photo based social media, part of producing creative content in this field involves artists interacting directly with their favorite brands through "product tagging" and other means of rapid networking. This energetic atmosphere of creativity and brand engagement presents a unique opportunity to introduce a footwear product specifically made for the brand-conscious visual artist. A collaborative shoe project between a major footwear brand such as Nike or Adidas and a major camera brand such as Canon or Sony is a unique and exciting way to meet the functional and aesthetic demands of this population.

The study was based on research done on the achievement goal theory. The purpose of the study was to discover if goal orientation would change after manipulation of the motivational climate. The study also was conducted to find if there was evidence of gender differences in motivational climate preference and satisfaction. These findings may help to provide a fun and motivating environment for all children in a physical activity setting. Investigators manipulated the climate to present lessons that were more task orientated in nature (mastery climate), and lessons that were more ego oriented in nature (performance climate). Participants consisted of girls and boys ages eight to ten years old (M = 9.5) recruited from a fourth grade P.E. class (n=42, females=20, males=22). The children participated in activities in a mastery and performance climate. The Task and Ego Orientation in Sport Questionnaire (TEOSQ), the Athlete in Sport Questionnaire (ASQ), and the Perceived Motivational Climate in Sport Questionnaire 2 (PMSQ-2) were administered. From the data it was concluded that there were no gender differences between baseline task and ego orientation scores. The children also did not perceive a performance climate after the performance climate intervention There were no gender differences in satisfaction following the mastery climate and the performance climate. The children's task and ego personal goal orientation scores on the PMCSQ-2 did not change following the mastery climate or the performance climate. There may be an absence of a gender difference in satisfaction and possessing either a task or ego orientation due to the factor of age. The student's regular PE coach enforces a mastery climate in their class, which may explain why the participants did not perceive a performance climate during the performance climate intervention. There were some methodological hurdles and problems in conducting the present study, which may account for the results.

The recovery of biofuels permits renewable alternatives to present day fossil fuels that cause devastating effects on the planet. Pervaporation is a separation process that shows promise for the separation of ethanol from biologically fermentation broths. The performance of thin film composite membranes of polydimethylsiloxane (PDMS) and zeolite imidazolate frameworks (ZIF-71) dip coated onto a porous substrate are analyzed. Pervaporation performance factors of flux, separation factor and selectivity are measured for varying ZIF-71 loadings of pure PDMS, 5 wt%, 12.5 wt% and 25 wt% at 60 oC with a 2 wt% ethanol/water feed. The increase in ZIF-71 loadings increased the performance of PDMS to produce higher flux, higher separation factor and high selectivity than pure polymeric films.

In this research, construction of a model membrane system using Polyvinylidene Chloride-Co Acrylonitrile and Linde Type A zeolites is described. The systems aims to separate out flow through zeolite pores and flow through interfaces between zeolites and polymers through the use of pore filled and pore open zeolites. Permeation tests and salt rejection tests were performed, and the data analyzed to yield approximation of separated flow through zeolites and interfaces. This work concludes the more work is required to bring the model system into a functioning state. New polymer selections and new techniques to produce the membrane system are described for future work.

This thesis aims to evaluate how in classroom demonstrations compare to regular education techniques, and how student learning styles affect interest in science and engineering as future fields of study. Science education varies between classrooms, but usually is geared towards lecture and preparation for standardized exams without concern for student interest or enjoyment.5 To discover the effectiveness of demonstrations in these concerns, an in classroom demonstration with a water filtration experiment was accompanied by several modules and followed by a short survey. Hypotheses tested included that students would enjoy the demonstration more than a typical class session, and that of these students, those with more visual or tactile learning styles would identify with science or engineering as a possible major in college. The survey results affirmed the first hypothesis, but disproved the second hypothesis; thus illustrating that demonstrations are enjoyable, and beneficial for sparking or maintaining student interest in science across all types of students.
