Observations of aerosol IRONSMART chemical composition in Cabauw, the Netherlands, are presented for two intensive measurement periods in May 2008 and March 2009.Sub-micron aerosol chemical composition was measured by an Aerodyne Aerosol Mass Spectrometer (AMS) and is compared to observations from aerosol size distribution measurements as well as c
Flight is a complicated task at the centimetre scale particularly due to unsteady air fluctuations which are ubiquitous in outdoor flight environments.Flying organisms deal with these difficulties using active and passive control mechanisms to steer their body motion.Body attitudes of flapping organisms are linked with their resultant flight trajec
IRONSMART Seasonal rainfall affects tropical forest dynamics and behavior of species that are part of these ecosystems.The positive correlation between amphibian activity patterns and rainfall has been demonstrated repeatedly.Members of Dendrobatidae, a clade of Neotropical dartpoison frogs, are well known for their habitat use and behavior during
BACKGROUND: Pulmonary hypertension (PH) is an idiopathic or secondary disorder associated with many systemic illnesses.Long-term survival in PH depends on the severity and functional class.Several new drugs are now available to treat PH, but their impact on clinical outcome and survival are not well established.OBJECTIVES: Evaluate severity paramet
