Ambient concentrations and gas/particle partitioning of Polybrominated Diphenyl Ethers (PBDEs) were investigated in a industrial, a traffic and a background site in the urban agglomeration of Thessaloniki, northern Greece. Atmospheric (gas+particle) concentrations of ∑12PBDE at industrial site were higher than those observed at urban-traffic and urban-background sites. In industrial site, mean ...

[1] Using cloud observations from NASA Moderate Resolution Imaging Spectroradiometer, Multiangle Imaging Spectroradiometer, and CloudSat-CALIPSO, composites of cloud fraction in southern and northern hemisphere extratropical cyclones are obtained for cold and warm seasons between 2006 and 2010, to assess differences between these three data sets, and between summer and winter cyclones. In both ...

The non-feeding postlarva (puerulus) of spiny lobsters actively swims from the open ocean to the coastal habitats where it settles and molts to the first-stage juvenile (JI). Because pueruli use much of their energy reserves swimming and preparing for the post-settlement molt, the survival of JIs presumably depends on resuming feeding as soon as possible. To test this hypothesis, the resistance...

OBJECTIVE Depression is a common cause of morbidity. Sufferers are very sensitive to many external factors. Emergency department (ED) visits for this condition can be associated with the concentration of ambient air pollutants. The study objective was to examine and assess the associations between ED visits for depression and ambient air pollution. DESIGN AND METHODS The present study analyze...

Cool-season (northern) and warm-season (southern) grasses are grown in Arkansas. Cool-season grasses grow best in the spring and fall and less actively in the summer. They stay reasonably green in the winter. Tall fescue (Festuca arundi­ nacea) is the most commonly grown cool-season grass in Arkansas. Warmseason grasses are slow to green up in the spring, grow best in the summer and go dormant ...

Switchgrass, Indiangrass, and big bluestem are warmseason grasses that are a suitable alternative for summer pasture in Iowa. Their advantage over cool-season grasses such as bluegrass, bromegrass, and orchardgrass is their ability to produce during midsummer. These warm-season perennial grasses start growing in late spring as air and soil temperatures increase. Leaf growth often occurs in earl...

To date very low scores are associated to quantitative precipitation forecasts (QPF) of warm season precipitation, a fact mostly due to the little knowledge of the mechanisms driving these phenomena. The study aims to produce a five-year climatology (1999–2003) of warm season precipitation systems (MJJA) over Europe using Meteosat IR brightness temperatures as a contribution to a global study l...
