The sensitivity of a marine dispersion model for non-conservative radionuclides, previously developed and validated for the English Channel, to parameters describing the exchanges between the liquid and solid phases (suspended matter and bottom…

Phyllosoma larvae collected to date in Japanese and Taiwanese waters have been classified into two genera (Linuparus, Panulirus) of the Palinuridae, four genera (Ibacus, Parribacus, Scyllarides, Scyllarus) of the Scyllaridae, and one genus…

Targeted radionuclide therapy (TRT) is an increasingly used treatment modality for a range of cancers. To date, few treatments have involved the use of dosimetry either to plan treatment or to retrospectively ascertain the absorbed dose delivered…
-
The aim of the present study is to review and tentatively to interpret the optical behavior of oceanic case I waters, those waters for which phytoplankton and their derivative play a predominant role in determining their optical properties.…
-
A number of processes are proposed to explain the time and space variability of the onset and decay of the spring phytoplankton bloom. This is done in the modeling framework of a case study most representative of the northwestern Mediterranean Sea…
-
Radiolabeled tracers provide a functional imaging technique to identify neuroendocrine tumors, usually with greater sensitivity and specificity than anatomic imaging techniques such as computed tomography (CT), magnetic resonance imaging and…
-
Preventing the introduction of potentially invasive species is becoming more important as this worldwide problem continues to grow. The ability to predict the identity or range of potential invaders could influence regulatory decisions and help to…
-
The multiinjection approach was used to study in vivo interactions between alpha4beta2() nicotinic acetylcholine receptors and 2-(18)Ffluoro-A-85380 in baboons. The ligand kinetics was modeled by the usual nonlinear compartment model composed of…
-
Availability of remotely sensed phytoplankton biomass fields has greatly advanced primary production modeling efforts. However, conversion of near-surface chlorophyll concentrations to carbon fixation rates has been hindered by uncertainties in…
-
The dependence of phytoplankton photosynthesis on light intensity may be altered by the range and frequency of variations in light intensity recently experienced by the organisms.

This paper presents results on the calibration and validation of a model (Ventomod) for leaf to fruit transfer of (134)Cs, (85)Sr and (65)Zn in processing tomato plants after leaf contamination. Several models (e.g. FARMLAND) that deal specifically…
-
Many marine organisms are sedentary as adults and are redistributed between generations by the oceanic transport of planktonic larvae. In order to assess interactions among oceanographic and biological processes that determine larval dispersal…
-
OBJECTIVE: The relative advantage of fully 3-D versus 2-D mode for whole-body imaging is currently the focus of considerable expert debate. The nature of 3-D PET acquisition for FDG PET/CT theoretically allows a shorter scan time and improved…
-
Most phytoplankton species have a tendency to sink. Phytoplankton require light for photosynthesis, however. Therefore, phytoplankton species that sink too fast will not be able to sustain a viable population in the euphotic zone. This points to the…
-
In the present study we assessed the radiocaesium uptake by plants in order to piece together information on factors affecting the uptake processes, particularly K supply and plant species differences. Vegetation uptake from soil contaminated by the…

A decade-long satellite altimeter data set is used to analyze the annual variations in the sea surface height (SSH) field northeast of the Hawaiian Islands. The annual harmonic amplitudes for the SSH and the along-island geostrophic flow are 2 - 4…
-
Liquid chromatography/mass spectrometry (LC/MS), combined with commercially available hepatocytes, has become an indispensable tool in evaluating the presence of these metabolites in target tissues, especially in the brain. Results from in vitro…
-
The relative distributions of mid- and late-stage phyllosomas, and pueruli, of Jasus edwardsii from five research cruises off the east coast of the North Island of New Zealand were analysed. A statistical approach was taken, using a boot-strapping…
