BSE (bovine spongiform encephalopathy) is a progressive neurological disorder of cattle, and has been called “mad cow disease.” Its symptoms are similar to “scrapie,” a brain disease that occurs in sheep. Cattle affected by BSE experience progressive degeneration of the nervous system. Affected animals may display changes in temperament, such as nervousness or aggression, abnormal posture, inco...

Traditional manufacturing solutions, based on centralized structures, are ineffective in unpredictable and volatile scenarios. Recent manufacturing paradigms, such as Holonic Manufacturing Systems, handle better these unpredictable situations but aren’t able to achieve the performance optimization levels displayed by the classical centralized solutions when the system runs without perturbations...

The purpose of this study was to determine whether psychological support associated with hormone replacement therapy (HRT) was more beneficial than replacement therapy alone. Our findings showed that HRT alone was more effective against vasomotor symptoms than HRT with psychological treatment (PT). While the combination of both treatment modalities (HRT + PT) was more effective against insomnia...

The problem is determining why an individual would carry out a costly behavior that benefits another. Possible solutions to this problem include kinship, repeated interactions, and policing. Another solution that has recently received much attention is the threat o...

Nearly two million more young Americans under the age of 30 voted in the 2008 presidential elections as compared to the 2004 elections, according to new Census data analyzed and released by CIRCLE.

Whil...

Webster’s asserts that color is “a phenomenon of light or visual perception that enables one to differentiate otherwise identical objects,” and then goes on to say that the Latin root is celare, “to conceal.” It’s a fine definition, because human perception of color is seamless to the extent that it conceals from us almost every causal detail. This talk will discuss common sources of light, the...

It is the product of my playing with beautiful geometric objects called rational cuspidal curves over the past two years. I would like to thank everyone who has contributed to this thesis. I owe so much to everyone who has ever taught me mathematics. Thank you for inspiring me and for providing me with the skills necessary to complete this thesis. To my friends and fellow students at Abel, than...
