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...

The binary star Algol is one of the most famous eclipsing binary stars in our night sky. Algol is useful because of its clockwork dimming every 2.87 days. This creates a frequent opportunity collect data using UBVRI filters during the primary eclipse, secondary eclipse, and non-eclipsing phases. Using the blackbody formula, a theoretical model of the number of counts for each filter and phase was created. When compared with the observed number of...

The acquisition and use of biomass fuels for heating and cooking presents a ubiquitous problem for the majority of people on three continents. Inefficient cooking and heating practices (wood burns at 5-8% efficiency and cow dung at 3-5%) not only pollute the home but deplete biomass resources and require increasing amounts of time and energy for fuel acquisition. These factors challenge the sustainability of local and global environments as well...

The Bristol Bay region of Alaska has had a sustaining salmon fishery for thousands of years. The area is filled with different Alaskan wild animals, the people of the region have this unique culture like no other, and the amount of freshwater in the region is only dreamed of in the Western United States. The proposed Pebble Mine, the largest proposed open pit mine in the world, would be built at the headwaters of the largest salmon fishery in the...

Metal carbenoids are useful intermediates capable of highly enantioselective C-H activations and cyclopropanation reactions among others. However, diazo compounds such as diazo glycines possessing a flanking nitrogen atom, apart from nitro groups, have not been reported. Progress toward the challenging synthesis of diazoglycines will be reported. A number of synthetic approaches particularly with regard to introduction of the diazo function were...

The purpose of this study was to investigate if salivary cortisol levels decrease, indicating lower stress levels, when humans are in an outdoor environment compared to an indoor environment. Salivary Cortisol is routinely used as a biomarker of psychological stress and related mental or physical diseases. Most studies consider salivary cortisol levels a reliable measure of hypothalamus-pituitary-adrenal axis (HPAA) adaption to stress (Hellhammer,...

A 20 year annual age class analysis of the brown trout (Salmo trutta) on the Dolores River was used to analyze the impacts of disease on the brown trout population. The historical data used the Seber and Le Cren 2-pass electro fishing sampling method. River flow values are strongly related to population. The Dolores, being a regulated river, has very predictable seasonality in annual flow cycles. Regional drought between 2001 and 2004 led to peak...

Bees play important role in many areas within almost all societies. The role of this genus of insect is often overlooked, despite the vital role that it plays in modern subsistence, culture, and other, less well-known areas. This research explores the role of bees through time and across cultures. By using an ecological anthropology approach, the relationship between bees and humans can be seen in a different light. Archaeological, historical and...

The aim of the study was to evaluate changes that occurred over time in the composition of the riparian community at the Lone Dome Recreational Area, below McPhee Dam on the Dolores River, Colorado. This site has been sampled by the Fort Lewis College Field Ecology class starting in 1988 to 2007. Percent cover of woody riparian vegetation (14 species) was measured along a 540 m line-transect. The effects of the dam (built in 1984) were hypothesized:...

Late Cretaceous (Campanian) tidal rhythmites are documented in the upper Menefee Formation at the Cliff House Sandstone transition near Durango, Colorado, USA. These tidal rhythmites are records of daily tidal cycles and also indicate the presence of diurnal or mixed diurnal tides in this portion of the Cretaceous Western Interior Seaway. The tidal rhythmites occur within beds at the base of lateral accretion surfaces in a fluvially connected deltaic...
