Formation And Removal Of Pesticides And Pesticide Transformation Products During Water Treatment, Evelyn F. Chamberlain Jan 2008

Formation And Removal Of Pesticides And Pesticide Transformation Products During Water Treatment, Evelyn F. Chamberlain

Doctoral Dissertations

"A comprehensive suite of over 60 pesticides (herbicides, insecticides, and fungicides) representing a variety of classes at environmentally relevant concentrations (low µg/L) were screened for reactivity under typical drinking water conditions and dosages. The most common oxidants/transformation agents in water treatment systems were examined for reactivity including free and combined chlorine, chlorine dioxide, permanganate, ozone, hydrogen peroxide, ultraviolet radiation, and high pH (alkaline hydrolysis). Due to the broad nature of the study, pesticide compounds were analyzed as multiple mixes broken into two groups based on analytical methods, those analyzed by GC/ECD and those by LC/MS. Combinations of reactive disinfectant/oxidant and …


Crude Birth Rates Among New York City’S Racial/Ethnic Groups And Latino Nationalities In 2002, Victoria Stone Jan 2008

Crude Birth Rates Among New York City’S Racial/Ethnic Groups And Latino Nationalities In 2002, Victoria Stone

Center for Latin American, Caribbean, and Latino Studies

Introduction: This report analyzes crude birth rates among women in the three primary racial/ethnic groups, White, Black, and Latina, and further examines birth rates by age-specific groups in the five boroughs of New York City in 2002. In addition, this report presents the crude birth rates for six Latino nationalities: Mexican, Ecuadorian, Dominican, Colombian, Puerto Rican and Cuban.

Methods: The data examined here was derived from the NYC Vital Statistics 2002 Report and the Census 2000 SF4 table on Sex by Age by race and Latino nationality. The birth rates were calculated by dividing live birth numbers (Vital Statistics report) …


Crude Birth Rates And Contraceptive Use By Racial/Ethnic Group In The U.S., 1990-2000, Victoria Stone Jan 2008

Crude Birth Rates And Contraceptive Use By Racial/Ethnic Group In The U.S., 1990-2000, Victoria Stone

Center for Latin American, Caribbean, and Latino Studies

Introduction: This report analyzes crude birth rates and contraceptive use among women in the three primary racial/ethnic groups, White, Black, and Latina, and further examines birth rates by age-specific groups in the United States between 1990 and 2000.

Methods: The data examined here was derived from the NYC Vital Statistics 2002 Report and the Census 2000 SF4 table on Sex by Age by race and Latino nationality. The birth rates were calculated by dividing live birth numbers (Vital Statistics report) by total population count by age and racial/ethnic group (Census 2000 data) and multiplying this number by 1000.

Results: In …


Energy Harvesting Using Piezoelectric Materials And High Voltage Scavenging Circuitry, Shahab Mehraeen, Jagannathan Sarangapani, Keith Corzine Jan 2008

Energy Harvesting Using Piezoelectric Materials And High Voltage Scavenging Circuitry, Shahab Mehraeen, Jagannathan Sarangapani, Keith Corzine

Electrical and Computer Engineering Faculty Research & Creative Works

Piezoelectric transducers are increasingly being used to harvest energy from environmental vibrations in order to power remote sensors or to charge batteries that power the sensors. In this paper, two modifications have been analyzed and tested to increase the harvested electrical power from a vibrating piezoelectric material. First, the voltage inversion method, which has recently been used in piezoelectricbased energy harvesting, and that shapes the voltage to be in phase with current in order to increase the harvested power is reviewed. By injecting additional current, a new voltage inversion scheme, referred as voltage compensation scheme, is introduced. This new scheme …
