Data was collected on the star WASP-43 in order to verify the presence of an expected orbiting planet, WASP-43 b, using the Photometric Transit Method. SuperWASP data was used to predict the transit time of the exoplanet, which was observed several times throughout the course of 5 months. Due to time and equipment constraints, only verification of the differential change in magnitude was possible. To accomplish this project, the coordinates for a...

Sudden aspen decline (SAD) is rapid mortality that results in the loss of whole aspen (Populus tremuloides) stands. Southwestern Colorado has the greatest occurrence of SAD in the state. The purpose of our study was to look at mycorrhizal associations in different levels of SAD. We conducted our study June-September 2010. Our study plots were located in the Dolores Ranger District of the San Juan National Forest in Southwestern Colorado. We quantified...

Art is a subjective term to many people. It can have a multitude of meanings ranging from purely aesthetic to a form of therapy, historical reference, or advertising. Without art, our world would look very different. It would not only look so, but it would be different as well. In addition to its ability to make a personal impact, art has served as an aid to political revolutions, social change, and community based transformations. The subject...

As a visual artist, the primary function of my work is to explore sensuality and how human beings experience existence through our senses. Inspiration for my work comes from many sources, and I am constantly struck by the connections in thought between other artists of varying disciplines. This is what led me to Informalism. The purpose of this research project was to discover the relevance and accessibility of Informalist art in a contemporary cultural...

The standard operating procedures (SOP) for the use of snow pickets were developed in maritime snow. The conditions created by continental snows differ greatly and require that the standards be evaluated. The purpose of this study was to evaluate the effectiveness of the SOP for the use of snow pickets as anchors and make recommendations for safer snow anchor systems that utilize snow pickets. We tested pickets in a variety of anchor systems according...

The discovery of prebiotic molecules in the interstellar medium (ISM) provides incentive to investigate the extraterrestrial formation of biomolecules. This study aims to illuminate potential interstellar synthesis pathways of nucleobase analogs by analyzing their gas phase dissociation patterns. Purine analogs are of particular interest as the location of functionalization directly effects the conjugation of electrons around the ring (Beste et al.,...

Natural products are organic compounds isolated from natural sources: plants, animals, bacteria, and fungi. Natural products and derivatives of natural products comprise more than two-thirds of the drugs approved by the FDA in the last 15 years, and as a result, natural product chemistry remains the major driving force in new drug discovery. Within this context, the sattazolins and sattabacins are natural products isolated from soil bacteria in...

Sattazolin is a natural product produced by the soil bacteria Bacillus sp. along with other structurally related acyloins sattabacin and 4-hydroxysattabacin. Our research group has previously reported the asymmetric total syntheses of sattabacin and 4-hydroxysattabacin, while the total synthesis of sattazolin had not been reported. Further, the isolation chemists reported an optical rotation for sattazolin but failed to determine the absolute configuration...

The first asymmetric total syntheses of the antiviral natural products (+)-sattabacin and (+)-4-hydroxysattabacin are reported. Progress toward the asymmetric total synthesis of (+)-sattazolin is also reported. These total syntheses are remarkably concise and were completed without the use of protecting groups. Unambiguous assignment of the absolute configuration of both (+)-sattabacin and (+)-4-hydroxysattabacin was also accomplished. The syntheses...

A method for producing high fidelity audio was explored utilizing a massless speaker. The design explored the best course of action regarding discharge type, modulation scheme and transformer construction. Specifically, a point to point discharge between two fixed electrodes was utilized. An audio signal modulated a fixed frequency, transformer driving, square wave using pulse width modulation. This signal was adequately amplified using a configuration...

The Hispanic community is underrepresented at Fort Lewis College and in the city of Durango, Colorado. Baile Folklorico is an important part of that culture, often serving as a symbol of Mexican heritage and tradition. Addressing the history and modern usage of the dance highlights issues faced by those associated with the Hispanic community, specifically, the issue of cultural continuance in a region where members face minority status. Data was...

There are increasing numbers of falls and injuries in the elderly population; one idea on how to reduce these rising numbers is to improve balance. Discovering which aspects are involved in improving balance in the elderly population is key to this. In some studies there are expensive large apparatuses involved in the exercise programs that seek to improve balance, but the goal of this study is to see if it is possible to improve balance test scores...

The search for mineral wealth in Colorado led to the exploration of isolated areas like Silver Lake Basin in the San Juan Mountains. As surface ores were exhausted, miners were forced to increase the depth of vertical shafts where they confronted increasingly complex ores that required sophisticated equipment and engineering expertise to extract. Remote communities like Silverton sought Eastern investment to provide the capital necessary for development,...

Sums of powers of integers arise in integration and in areas of probability. Patterns within these sums of powers gave rise to a series of numbers named Bernoulli Numbers. These numbers are useful in determining other closed forms of sums of powers as well as in determining certain probabilities.

The purpose of this project is to design a bicycle-powered system to generate electricity for off-grid users. The system consists of a bicycle, a generator wired to a charge controller, 12 volt deep cycle battery, and an inverter. A charge controller controls current going into the battery. Lastly, the inverter converts 12 volt DC into alternating current (AC) which can be used for house appliances. The electric power produced will be determined by...
