The Toxic Effects of Cigarette Additives. Philip Morris' Project Mix Reconsidered: An Analysis of Documents Released through Lit

submitted by: glantz
This video describes the peer reviewed paper, Wertz MS, Kyriss T, Paranjape S, Glantz SA (2011) The Toxic Effects of Cigarette Additives. Philip Morris' Project Mix Reconsidered: An Analysis of Documents Released through Litigation. PLoS Med 8(12): e1001145. doi:10.1371/journal.pmed.1001145 Background In 2009, the promulgation of US Food and Drug Administration (FDA) tobacco regulation focused attention on cigarette flavor additives. The tobacco industry had prepared for this...

Photo-Physics and Renewable Energy Applications of Single-Walled Carbon Nanotubes

submitted by: RASEIBoulder
Summary: Single-walled carbon nanotubes (SWNTs) are two-dimensionally confined quantum wires that have the potential to impact a variety of renewable energy applications. SWCNTs have several fundamental properties that make them attractive for sustainable energy conversion technologies, including high electron and hole mobilities, size-tunable ionization potentials and electron affinities in an energy range relevant to many photovoltaic devices, and optical transitions in the visible and...

SDSU Geological Sciences - Thesis Defense - Marck Maroun

Saprock: A long term recorder of ground shaking, Peninsular Ranges, southern California Marck Maroun ABSTRACT Saprolization is commonly viewed as an isovolumetric process. However, it has not been studied extensively in seismogenic areas. Hence, we undertook a detailed study of five sites located at disparate distances to the seismically active Elsinore fault. Data obtained during this study along with the results of earlier investigation of five additional sites, support the idea of...

Correcting for Inflammation Changes Estimates of Iron Deficiency among Rural Kenyan Preschool Children

submitted by: ebogrant5
The assessment of iron status where infections are common is complicated by the effects of inflammation on iron indicators and in this study we compared approaches that adjust for this influence. Blood was collected in 680 children (aged 6–35 mo) and indicators of iron status [(hemoglobin (Hb), zinc protoporphyrin (ZP), ferritin, transferrin receptor (TfR), and TfR/ferritin index)] and subclinical inflammation [(the acute phase proteins (APP) C-reactive protein (CRP), and a-1-acid...

In Bruce Logan's lab at Penn State Univeristy, researchers are working on developing microbial fuel cells (MFC) that can generate electricity I while accomplishing wastewater treatment. In a project supported by NSF, they are researching methods to increase power generation from MFCs while at the same time recovering more of the energy as electricity. Through their research projects, Logan’s team has already proven that they can produce electricity from ordinary domestic wastewater, as well...
