Hammond, Daniel G.; Bridgham, April; Reichert, Kara; Magers, Martin – Journal of Chemical Education, 2010
Much of our understanding of metabolic pathways has resulted from the use of chemical and isotopic labels. In this experiment, a heavy isotope of carbon, [superscript 13]C, is used to label the product of the well-known RuBisCO enzymatic reaction. This is a key reaction in photosynthesis that converts inorganic carbon to organic carbon; a process…

Cohen, Bruce H. – Developmental Disabilities Research Reviews, 2010
The vast majority of energy necessary for cellular function is produced in mitochondria. Free-radical production and apoptosis are other critical mitochondrial functions. The complex structure, electrochemical properties of the inner mitochondrial membrane (IMM), and genetic control from both mitochondrial DNA (mtDNA) and nuclear DNA (nDNA) are…

Schaffhauser, Dian – T.H.E. Journal, 2009
Most smart technology leaders can name multiple efforts they have already taken or expect to pursue in their schools to "green up" IT operations, such as powering off idle computers and virtualizing the data center. One area that many of them may not be so savvy about, however, is hardware disposal: "What to do with the old stuff?" After all, it…

Lazarus, Philip J.; Sulkowski, Michael L. – Communique, 2010
On April 20, 2010, a massive explosion killed 11 workers on the Deepwater Horizon oil rig. Survivors of this explosion recounted terrifying near-death experiences and mourned the loss of coworkers and friends who had perished. Shock and grief spread through small coastal communities composed mostly of fishers and oil workers. However, this was…

Kumar, G. D. S.; Popat, M. N. – Journal of Agricultural Education and Extension, 2010
One of the major impediments for diversification of groundnut ("Arachis Hypogaea" L.) as food crop is aflatoxin contamination. The study was conducted with an objective to assess the adoption gaps in aflatoxin management practices of groundnut (AMPG) and the farmer's characteristics influencing these gaps. The study used an expost-facto…

Grineski, Sara E.; Collins, Timothy W.; Aguilar, Maria de Lourdes Romo; Aldouri, Raed – Social Forces, 2010
This article examines spatial relationships between environmental hazards (i.e., pork feed lots, brick kilns, final assembly plants and a rail line) and markers of social marginality in Ciudad Juarez, Mexico. Juarez represents an opportunity for researchers to test for patterns of injustice in a recently urbanizing metropolis of the Global South.…

Blaiszik, Benjamin James – ProQuest LLC, 2009
Damage in polymeric coatings, adhesives, microelectronic components, and composites spans many length scales. For small scale damage, autonomic self-healing can repair multiple damage modes without manual intervention. In autonomic self-healing materials, a healing response is triggered by damage to the material. Size scale considerations, such as…

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…

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…
