The European Space Agency (ESA) and the European Southern Observatory (ESO) initiate a definition study for a Ground-based European Nulling Interferometer Experiment (Darwin-GENIE). The experiment will use the Very Large Telescope Interferometer (VLTI) operating on Mount Paranal (Chile). The objective of GENIE is to gain experience in the manufacture and operation of a nulling interferometer using a design concept and technology representative of the ESA IRSI-Darwin space mission. GENIE will prepare the IRSI-Darwin science program through a systematic search for exozodiacal dust clouds around IRSI-Darwin candidate targets. GENIE also aims to perform IRSI-Darwin related science achievable from ground including the detection of low-mass companions (if possible, hot jupiters) around nearby stars. Among the variety of telescope sizes and positions on the VLTI site, candidate interferometric configurations have been identified for GENIE, taking into account the limitation imposed by the Earth's atmosphere. They include a Bracewell interferometer for exozodiacal clouds detection in the N band and a double Bracewell configuration with internal modulation for extrasolar jupiter detection in the L' band. The present paper presents the prospective performance of these configurations in light of current specifications of major VLTI subsystems. [less ▲]

A novel autonomous measuring device that acquires the partial pressure of CO2 (pCO2) by equilibration and several other parameters is described. This device, the Floating Equilibrator System (FES) was tested in field conditions for the first time in the Great Bahama Bank, in December 2000. We successfully carried out two 24 h cycles in Norman’s Pond, one in front of the Caribbean Marine Research Centre (CMRC) and another one near Bock Cay. Over-saturation of CO2 with respect to atmospheric equilibrium was observed systematically at the three sites, although significantly more marked at Norman’s Pond. The higher values of pCO2 and atmospheric CO2 fluxes obtained at Norman’s Pond, than in the adjacent open waters of the Great Bahama Bank, suggest a comparatively stronger heterotrophy at Norman’s Pond. This is most likely related to the organic carbon inputs to the water column and sediments from the dense mangrove forest surrounding Norman’s Pond. The larger amplitude of pCO2 daily variations observed, during the Norman’s Pond 24 h cycles, is probably due to higher biological activity than in the adjacent open waters of the Great Bahama Bank. This is corroborated by a tentative estimation of Gross Primary Production based on simple computations. We speculate that calcification could also contribute to some extent to different amplitude of the pCO2 daily variations between the mangrove pond and the open waters of the Great Bahama Bank.

In Belgium, the Boom Clay is being considered as a potential host formation for the disposal of nuclear waste. Part of the safety assessment and feasibility studies of a potential nuclear waste disposal consists of hydrogeological modeling. In order to model the groundwater flow and possible radionuclide transport in the clay, the spatial distribution of the hydraulic conductivity of the clay has to be assessed. In this study, geostatistical methods are used to characterize the hydraulic conductivity field. More specific, direct sequential simulation of the hydraulic conductivity is carried out, using measurements of hydraulic conductivity and 4 types of soft data or secondary variables: resistivity logs, gamma ray logs, grain size measurements and descriptions of the lithology. The primary and secondary information is analyzed with geostatistical tools and combined to generate 100 fields of the hydraulic conductivity of the Boom Clay. Next, each field is input to a groundwater flow model to predict the advective travel time of constituents released from the disposed waste in the Boom Clay to the aquifers surrounding the Boom Clay. Statistical analysis of the ensemble of model predictions results in a predictive distribution for the advective travel time. This distribution reflects the uncertainty of the advective travel time that results from the uncertainty of the spatial distribution of the hydraulic conductivity of the Boom Clay [less ▲]

Radiopharmaceuticals are used to detect and characterise disease processes, or normal biological function, in living cells, animals or humans. Used as tracer molecules, they map the distribution, uptake and metabolism of the molecule in clinical studies, basic research or applied research. The area of radiopharmaceuticals is expanding rapidly. The number of PET centers in the world is increasing at 20% per year, and many drug companies are utilising PET and other forms of radiopharmaceutical imaging to evaluate products. * Readers will find coverage on a number of important topics such as radionuclide production, PET and drug development, and regulations * Explains how to use radiopharmaceuticals for the diagnosis and therapy of cancer and other diseases [less ▲]

Models of alpha Cen A & B have been computed using the masses determined by Pourbaix et al. (2002) and the data derived from the spectroscopic analysis of Neuforge and Magain (1997). The seismological data obtained by Bouchy and Carrier (2001, 2002) do help improve our knowledge of the evolutionary status of the system. All the constraints are satisfied with a model which gives an age of about 6 Gyr for the binary. [less ▲]

[1] The distribution and sources of organic and inorganic carbon were studied in the Gautami Godavari estuary (Andhra Pradesh, India) and in a mangrove ecosystem in its delta during pre-monsoon. In the oligohaline and mesohaline section (salinity 0–15) of the estuary, internal production of total alkalinity (TAlk) and dissolved inorganic carbon (DIC) was recorded, and the d13CDIC profile suggests that carbonate dissolution may be an important process determining the DIC dynamics in this section of the Godavari. The partial pressure of CO2 (pCO2) was fairly low along the entire salinity gradient, (293–500 ppm), but much higher and more variable (1375–6437 ppm) in the network of tidal mangrove creeks in the delta. Here, variations in the concentration and d13C of the DIC pool were shown to result largely from the mineralization of organic matter. The present study clearly identifies the mangrove creeks as an active site of mineralization and CO2 efflux to the atmosphere, but shows that these changes in the aquatic biogeochemistry are a localized feature, rapidly fading in the adjacent Kakinada Bay. Our data indicate that mineralization of dissolved organic carbon (DOC) of mangrove origin, and its subsequent efflux as CO2 to the atmosphere may represent an important fate for mangrove carbon. Although further quantification of this process in a variety of systems is required, we suggest that some of the current ideas on the role of mangroves in the carbon budget of the coastal zone may need to be reconsidered.
