HAL is a multi-disciplinary open access archive for the deposit and dissemination of scientific research documents, whether they are published or not. The documents may come from teaching and research institutions in France or abroad, or from public or private research centers. L’archive ouverte pluridisciplinaire HAL, est destinée au dépôt et à la diffusion de documents scientifiques de niveau...

absorbing inner core surrounded by a non-absorbing shell—revealed that many particles are actually shaped differently. • Measurements of black carbon in the atmosphere around urban centers in California indicate that when black carbon mixes with other atmospheric components, the particle’s ability to absorb light and generate heat is significantly less pronounced than often simulated in global ...

The simulated mean January and July climates of four versions of the National Center for Atmospheric Research (NCAR) Community Climate Model (CCM) are compared. The models include standard configurations of CCM1 and CCM2, as well as two widely-cited research versions, the Global Environmental and Ecological Simulation of Interactive Systems (GENESIS) model and the Climate Sensitivity and Carbon...

N2O release from agro-biofuel production negates global warming reduction by replacing fossil fuels P. J. Crutzen, A. R. Mosier, K. A. Smith, and W. Winiwarter Max Planck Institute for Chemistry, Department of Atmospheric Chemistry, Mainz, Germany Scripps Institution of Oceanography, University of California, La Jolla, USA International Institute for Applied Systems Analysis (IIASA), Laxenburg,...

Numerical model scenarios of future climate depict a global increase in temperatures and changing precipitation patterns, primarily driven by increasing greenhouse gas (GHG) concentrations. Aerosol particles also play an important role by altering the Earth’s radiation budget and consequently surface temperature. Here, we use the general circulation aerosol model ECHAM5-HAM, coupled to a mixed ...

BACKGROUND Laboratory request forms provide information about the laboratory test being requested for. They carry demographic data and other information such as location of patient, laboratory number, doctor's name, signature of the doctor, telephone number of the requesting doctor. Omission of information on the forms may lead to laboratory errors. The aim of this study was to evaluate the lev...

Observation in absolute darkness and daytime under every atmospheric situation is one of the advantages of thermal imaging systems. In spite of increasing trend of using these systems, there are still lots of difficulties in analysing thermal images due to the variable features of pedestrians and atmospheric situations. In this paper an efficient method is proposed for detecting pedestrians in ...

Background & Aims: Generalized anxiety disorder (GAD) can be affected by different emotional, cognitive, and natural factors. The purpose of this study was to predict GAD based on emotion regulation deficits, thought-action fusion, and behavioral inhibition. Methods: This was a correlational study. The study sample was comprised of 135 patients with GAD selected from amo...

We apply a simple dynamical rule to determine the dominant forcing direction in locally coupled oceanatmosphere anomalies in the National Centers for Environmental Prediction/National Center for Atmospheric Research (NCEP/ NCAR) reanalysis data. The rule takes into account the phase relationship between the low-level vorticity anomalies and the Sea Surface Temperature (SST) anomalies. Analysis ...
