Saat, Mohd Rapik – ProQuest LLC, 2009
The design of railroad tank cars is subject to structural and performance requirements and constrained by weight. They can be made safer by increasing tank thickness and adding various protective features, but these increase the weight and cost of the car and reduce its capacity and consequent transportation efficiency. Aircraft, automobiles and…

Roman, Harry T. – Technology Teacher, 2009
The quality of drinking water has been gaining a great deal of attention lately, especially as water delivery infrastructure continues to age. Particles of various metals such as lead and copper, and other substances like radon and arsenic could be entering drinking water supplies. Spilled-on-the-ground hydrocarbon-based substances are also…

Davis, Georgina; Wolski, Malcolm – International Journal of Sustainability in Higher Education, 2009
Purpose: This paper seeks to provide details of Griffith University's (GU) approach for sustainably dealing with electronic waste (e-waste) and the benefits of using the e-waste programme as a valuable educational case study for ESD. Design/methodology/approach: The e-waste programme is explained with reference to key resources and literature, so…

Timerman, Anthony P.; Fenrick, Angela M.; Zamis, Thomas M. – Journal of Chemical Education, 2009
A sequence of exercises for the isolation and characterization of invertase (E.C. 3.1.2.26) from baker's yeast obtained from a local grocery store is outlined. Because the enzyme is colorless, the use of colored markers and the sequence of purification steps are designed to "visualize" the process by which a colorless protein is selectively…

Toglia, Thomas V. – Tech Directions, 2009
Career and technical education (CTE) educators, administrators, and students face greater potential for risk than most of their academic counterparts due to the physical and hands on nature of nearly all disciplines found in CTE. As a consequence, CTE professionals must maintain a safe environment for their students and themselves. In this…

Stephenson, John B. – US Government Accountability Office, 2010
Exposure to toxic chemicals or environmental pollutants may harm the health of the nation's 74 million children and contribute to increases in asthma and developmental impairments. In 2007, 66 percent of children lived in counties exceeding allowable levels for at least one of the six principal air pollutants that cause or aggravate asthma,…

Gilbert, Steven G.; Miller, Elise; Martin, Joyce; Abulafia, Laura – Journal of Intellectual & Developmental Disability, 2010
Damage to the brain or nervous system at an early developmental stage creates lifelong challenges for the individual. To examine one source of harm to the developing nervous system, the Collaborative on Health and the Environment's (CHE) Learning and Developmental Disabilities Initiative (LDDI) (Collaborative on Health and the Environment, 2009)…

Huck, Lawrence A.; Leigh, William J. – Journal of Chemical Education, 2010
A modification of the mixed-aldol synthesis of dibenzylideneacetone, prepared from acetone and benzaldehyde, is described wherein acetone is replaced with a series of cyclic ketones with ring sizes of 5-7 carbons. The structural variations in the resulting conjugated ketones produce regular variations in the UV-vis absorption spectra. The choice…

McElgunn, Barbara – International Journal of Disability, Development and Education, 2010
A large body of experimental animal research on the neurotoxic effects of certain environmental chemicals provides evidence of a cascade of neurobehavioural effects including learning deficits, hyperactivity, anxiety, depression, lack of motivation, increased aggressiveness, altered maternal care and bonding, and an over-reaction to small…

Murchison, Stuart B. – New Directions for Institutional Research, 2010
Geographic information systems (GIS) are a major component of the geospatial sciences, which are also composed of geostatistical analysis, remote sensing, and global positional satellite systems. These systems can be integrated into GIS for georeferencing, pattern analysis, visualization, and understanding spatial concepts that transcend…

Munene, Ishmael I.; Ruto, Sara J. – International Review of Education, 2010
Since 1948, various UN conventions have recognised basic education as a human right. Yet this right continues to be denied to many child labourers across the world. This articles draws on the results of a study examining how children in domestic labour in Kenya access and participate in education. Three issues were explored: (1) the correlates of…

Bruce, Heather E. – English Journal, 2011
The relatively new fields of ecocriticism in literary studies and ecocomposition in rhetoric and composition studies provide a usable foundation for those interested in green(ing) English. Nevertheless, even suggesting that interest in the environment within English studies is a relatively new concern is somewhat misleading. Contemplation of…

Rosenbaum, Sara; Blum, Robert – Future of Children, 2015
The past century has seen vast improvements in our children's health. The infectious diseases that once killed huge numbers of children have largely been conquered. Infant mortality has also fallen markedly, although the United States lags behind other industrialized nations in this and other measures of children's health. Accidents and injuries…

Valcik, Nicolas A. – New Directions for Institutional Research, 2010
Research advancements into different fields of study have increased the risks for accidents, criminal acts, or a potential breach of national security, and the types of hazardous materials (HAZMAT) stored and used at universities and colleges are under new scrutiny. Before, a chemistry laboratory might only have basic substances such as sulfur,…

Liu, Sophia B. – ProQuest LLC, 2011
Unprecedented uses of information and communication technology (ICT) and particularly social media (e.g., Wikipedia, Facebook, and Twitter) are occurring in times of crisis. This dissertation investigates the socio-technical practices emerging from the use of social media and how these practices help to "sustain the living heritage" of…
