The Analysis Of Ion Flow Between The Human Body And Local Ground, Paul T. Rioux Apr 2012

The Analysis Of Ion Flow Between The Human Body And Local Ground, Paul T. Rioux

Honors Theses and Capstones

The project was designed to get a better sense of the phenomenon referred to as Earthing. Earthing is defined as the process where the human body is in contact with the earth and can freely transfer ions between the Earth and itself. Those promoting the idea of earthing say that this transfer of ions is important in maintaining a healthy immune system, and they claim that the recent increase in autoimmune diseases is the result of humans being insulated from the ground because of the shoes they wear and the places in which they live.


Investigation Of New Hampshire Hydropower Potential, Maxwell Murray Apr 2012

Investigation Of New Hampshire Hydropower Potential, Maxwell Murray

Honors Theses and Capstones

The popularity of green and renewable energy has risen sharply in recent years, and hydropower has consistently been the most common form of renewable energy in both the US and the state of New Hampshire. As a result of this strong green movement, government organizations have seen increased pressure to produce figures to the public detailing the amount of hydropower potentially available in the country. Often these figures will depict very attractive numbers for the untapped hydropower potential in the country, yet the data do not seem realistic to anyone familiar with hydropower generation. This paper will attempt to de-rate …


Arched Bridges, Lily Beyer Apr 2012

Arched Bridges, Lily Beyer

Honors Theses and Capstones

An exploration of arched bridges through history. Influence lines for three-pinned and two-pinned arches for moment and axial load are developed. An analysis of the Chesterfield Brattleboro Bridge is included


Estimating Connecticut Stream Temperatures Using Predictive Models, Erik Carlson Apr 2012

Estimating Connecticut Stream Temperatures Using Predictive Models, Erik Carlson

Honors Theses and Capstones

The Connecticut Department of Energy and Environmental Protection (CT DEEP) seeks to better classify their streams into thermal regimes (cold, cold transitional, warm transitional, and warm water). A prediction model was created based upon physical characteristics such that CT DEEP could classify streams into thermal regimes based upon the parameters described in Lyons et al. 2009 and compare them to their own classification system. Accurately classifying these thermal regimes determines the environmental protection provided to a stream as well as the potential for establishing fisheries.


Electrochemical Deposition Of Ag-Sn Nanoparticles For Photovoltaic Current Collection Efficiency, Rebecca Wilson Apr 2012

Electrochemical Deposition Of Ag-Sn Nanoparticles For Photovoltaic Current Collection Efficiency, Rebecca Wilson

Honors Theses and Capstones

Photovoltaic cells utilize a semiconductor to harness the sun's energy, then conduct the energy by silver current collector lines to an energy storage device. To make photovoltaic cells less expensive and more energy efficient, silver-tin nanoparticles were researched to incorporate into the silver polymer paste that makes up current collector lines. The Ag-Sn alloy was synthesized by electrochemical deposition, and was then characterized by it's melting point and crystal structure.
