Private Universe Project in Mathematics: Workshop 2. Are You Convinced?
Proof making is one of the key ideas in mathematics. Looking at teachers and students grappling with the same probability problem, we see how two kinds of proof—proof by cases and proof by induction—naturally grow out of the need to justify and convince others.,Englewood, New Jersey—Teachers Workshop Englewood, a town with unsatisfactory student test scores, is implementing a long-term project to improve math achievement.

586 Million Year Cycle in Geology Matches Galactic Super-Cluster Spacings
The longest geological cycle identified is described as about 600 million years in "Megacycles", the proceedings of a geological conference, Edited by G Williams. However Prof. S. Afanasiev of Moscow has determined the cycle very accurately to be 586.24 million years using his Nanocycles Method. It so happens that cosmologists, Broadhurst, T.J., Ellis, R.S., Koo, D.C. & Szalay (Nature 343, p 726) have observed regular mega-walls of galaxies at spacings that they describe as 128 Mpc/h, which base

HEALTHY INDIANA – A MINORITY HEALTH PLAN FOR THE STATE OF INDIANA
We are proud to present the Healthy Indiana - Minority Health Plan for the State of Indiana. This is another significant step forward in addressing the health disparities of minorities in our state. In March 2002, the Institute of Medicine (IOM) released a report with startling revelations about health care delivery for minorities. The report was titled "Unequal Treatment: What Healthcare Providers Need to Know About Racial and Ethnic Disparities in Healthcare." Not surprisingly, the IOM found t

Neither Victim nor Villain: Nurse Eunice Rivers, the Tuskegee Syphilis Experiment, and Public Health
From 1932 to 1972 white physicians of the United States Public Health Service (USPHS) carried out an experiment on approximately 400 rural black men in Macon County, Alabama. The study, which historian James Jones has described as "the longest nontherapeutic experiment on human beings in medical history," was predicated on following the course of untreated syphilis until death. 1 Historians have focused on the study as scientifically unjustifiable and as an unethical experiment that highlights t

The Persistence of American Indian Health Disparities
Disparities in health status between American Indians and other groups in the United States have persisted throughout the 500 years since Europeans arrived in the Americas. Colonists, traders, missionaries, soldiers, physicians, and government officials have struggled to explain these disparities, invoking a wide range of possible causes. American Indians joined these debates, often suggesting different explanations. Europeans and Americans also struggled to respond to the disparities, sometimes

Childhood Adversity and Later Mortality in an Urban African American Cohort
The Woodlawn Project is a longitudinal study of the development of psychological well-being and social adaptation in an epidemiologically defined cohort of African American first graders interviewed as adolescents and again as adults. The identification of childhood factors predictive of mortality has clear public health importance. Family and childhood adversity and psychosocial factors have been shown to have long-term effects on later mental health and school achievement in adolescence and yo

Chicano y Chicana: income differences among the largest U. S. Hispanic population
This study focuses on the wage gap between Mexican American men and Mexican American women, and factors contributing to this disparity. People of Mexican descent make up 67% of the U.S. Hispanic population. Previous research tends to lump Hispanics together, masking differences between groups. Even more, studies considering Hispanic subgroups rarely examine gender differences on income.

Building a testbed for mini quadrotor unmanned aerial vehicle with protective shroud
Potential applications of small rotorcraft unmanned aerial vehicles (UAVs) range from military missions to exploration of the planet Mars (Patrick C. O’Brien, 2003). Tasks such as exploration of unknown territories, formation flying, intelligence gathering etc, require UAV to be capable of flying very close to other flying or steady objects. Exposed rotary wings limit rotorcraft vehicle’s capability to fly in proximity of other objects. In some applications, such as rescue operation, urban w

Prediction of variation in dimensional tolerance due to sheet metal hydroforming using finite elemen
Hydroforming of aluminum sheets is very important in the aircraft industry, due to the advantages of less wrinkling and cost effectiveness. Numerous research has been conducted in this field, which deals with the development of methods and tools to control accuracy of the bend and prediction of the springback after the sheet metal has been formed. Rivets are the most commonly used fasteners to fit together the subassemblies of the aircraft. The holes for riveting are punched after any forming op

Prediction of crack growth in aircraft engine bleed air ducts using finite element and crack growth
The bleed air system in an aircraft engine is one of the most important systems for flight operation and is the heart of the aircraft engine pneumatic system. It consists of ducts and components that supply high pressure bleed air from the engine compressor to the other systems. The functioning of bleed air system plays a vital role in flight safety, ground operations, and coordination with other existing systems [1] including fuel system, lubrication system, ignition system, and anti-ice system
