The MIRAGE-Shanghai experiment was designed to characterize the factors controlling regional air pollution near a Chinese megacity (Shanghai) and was conducted during September 2009. This paper provides information on the measurements conducted for this study. In order to have some deep analysis of the measurements, a regional chemical/dynamical model(More)
In the guinea pig, the narrow part of the epididymis that traverses the upper pole of the testis and passes downward over the entire length of the gonad is composed exclusively of efferent ductules and the initial segment (zone I) of the epididymal duct. At the beginning of zone II, the narrow contour of zone I expands into a large globular region which(More)
Invasive plant species impact both ecosystems and economies worldwide, often by displacing native biota. Many plant species exude/emit compounds into the surrounding environment with minor consequences in their native habitat due to a long coevolutionary history. However, upon introduction to ecosystems naïve to these compounds, unpredictable interactions(More)
[1] The Ozarks Isoprene Experiment (OZIE) was conducted in July 1998 in Missouri, Illinois, Indiana, and Oklahoma. OZIE was designed to investigate the presumed strong isoprene emission rates from the Missouri Ozarks, where there is a high density of oak trees that are efficient isoprene emitters. Ground, balloon, and aircraft measurements were taken over a(More)
The Ozarks Isoprene Experiment (OZIE) was conducted in July 1998 in Missouri, Illinois, Indiana, and Oklahoma. OZIE was designed to investigate the presumably high isoprene emission rates from the Missouri Ozarks due to its high density of oak trees. Ground, balloon, and aircraft measurements were taken over a three-week study period; 0-D and 3-D chemical(More)
The persistence of gibberellin A3 on plant surfaces was examined using fruit of ‘Marsh’ seedless grapefruit (Citrus paradisi Macf.) and an inert glass model system. 14C-gibberellin A3 was applied to surfaces in aqueous treatment solutions or in waxing solutions. Dried-out treatment residues were removed by washing and analyzed for total and GA3-like(More)
Volatile organic compounds (VOC) are key species in atmospheric chemistry because of their reactivity and roles as pollutants, precursors to ozone (O3, an air toxic and greenhouse gas), and as greenhouse gases themselves. Fine carbonaceous particles also have important atmospheric impacts such as effects on radiative transfer (through light scattering and(More)
PURPOSE We have previously described the development and testing of a coherent-scatter spectral imaging system for identification of cancer. Our prior evaluations were performed using either tissue surrogate phantoms or formalin-fixed tissue obtained from pathology. Here we present the first results from a scatter imaging study using fresh breast tumor(More)
