A Study Into The Use Of Microprocessor Relays For Motor Operated Valve (Mov) Electrical Protection In Nuclear Power Plants, James Andrew Tuccillo

Master's Theses

Motor Operated Valves (MOVs) are electro-mechanical components used to isolate, divert, or introduce fluid flow. The use of microprocessor relays for actuator motor electrical protection within nuclear power plants is the focus of this thesis and is implemented by providing a new and enhanced protection scheme that provides the adequate conservatism necessary to ensure valve operation while still maintaining electrical safety and continued operational availability. The comprehensive protection scheme is designed around an advanced microprocessor relay that has the ability to simulate the thermal overload conditions of a motor operating into a destructive thermal region. Through laboratory testing, the validity …

Rape As A Weapon Of War In The Democratic Republic Of The Congo, Carly Brown

Social Sciences

The Democratic Republic of the Congo has been appropriately acknowledged as "the rape capital of the world." While the country has been trapped in conflict, the use of rape as a weapon of war has been rampant and unyielding. The sexual violence inflicted upon women has been nothing less than brutal and destructive, physically, socially, and psychologically. This paper analyzes the use of rape as a weapon of war in the Congo, taking into context the ongoing war, cultural and social situations that facilitate its existence, and the many consequences the victims are forced to endure.

Combating Childhood Obesity In California, Janelle Borelli

Social Sciences

Childhood obesity has become a major problem in Corporate America.  Our youth’s health is at risk, the statistics are alarming, and childhood obesity is largely preventable.  In order to solve the childhood obesity epidemic, government action, both state and federal, needs to be taken by passing nutrition standard laws.  Also, the built environment should support an active lifestyle rather than one based on fast food and lack of exercise.  Families should adopt a healthy lifestyle including having adequate fruits and vegetables at home along with exercising daily.

Adolescent Lifestyle Factors And Adult Breast Density In U.S. Chinese Immigrant Women, Marilyn Tseng, Temitope O. Olufade, Kathryn A. Evers, Celia Byrne

Kinesiology and Public Health

We examined recalled measures of adolescent diet, physical activity, and body size in relation to adult breast density in 201 U.S. Chinese immigrant women recruited in January 2002 to May 2003 from Philadelphia region screening programs. Mammographic images were classified into 1 of 4 categories ranging from “entirely fatty” to “extremely dense.” Questionnaires assessed diet and physical activity between ages 12–17, relative weight and height at age 10, and weight at age 18. To estimate odds ratios (ORs), we conducted logistic regression analyses using proportional odds models for polychotomous outcomes. Higher adult breast density was significantly associated with adolescent red …

Advertising Trends For The Hispanic Market, Vanessa Parra

Growing Conflict: Agriculture, Innovation, And Immigration In San Luis Obispo County, 1837–1937, Douglas P. Jenzen

Master's Theses

The history of San Luis Obispo and its surrounding areas is complex. Agriculture, innovation, and immigration have all contributed to the formation of the region. The Spanish, Mexican, and early American periods established the framework successive waves of immigrants had to live within. Native Americans and immigrants from China, Portugal, Switzerland, Japan, the Philippines, and other regions of the United States have all toiled in the fields and contributed to America’s tables at various points throughout county history. Many contingencies determined the treatment of successive waves of immigrants. Growth and development are taking place at exponential rates on the very …

The State Of Software Engineering Maturity And Licensure, Travis Lawrence Dean

Master's Theses

IEEE-CS is pursuing licensing for software engineers, but ACM believes that software engineering is too immature, and regulating the profession would be premature. In 1996, Norman Gibbs and Gary Ford from Carnegie Mellon University performed a qualitative survey of the maturity of the software engineering profession. I apply this model to the present state of the art in software engineering and analyze the results for 2010. I analyze the maturity of software engineering to determine that the profession is not yet ready for licensure. This is not because the infrastructure of software engineering is too immature, but because we have …

'Better Make It A Double': Perceived Relatedness Increases Reported Attractiveness, Benjamin R. Ainley

Master's Theses

Sexual selection shaped psychological mechanisms in both sexes to assess potential mates for evidence of mate quality (Buss, 2005). Attraction preferences are one such mechanism (Sugiyama, 2005) and physical attraction preferences are sensitive to fitness-promoting traits present in a potential mate. Physically attractive traits are thought to act as signals of good genetic quality (Neff & Pitcher, 2005) and are preferred because of the advantage such quality bestows towards reproductive success. Specifically, genetic quality is proposed to be a biological requirement necessary for physically attractive traits to develop and be maintained (Johnstone & Grafen, 1993). Furthermore, genetic quality is heritable …
