VIMOS and NIRMOS are two multi Object Spectrographs being developed for the VLT. Their main scientific characteristic is the high multiplexing capability, allowing to obtain up to 800 spectra per exposure. To achieve such a high efficiency, a number

Self-absorption corrections have been determined for the energies characterising 129 I below 40 keV in the frame of studying Fucus serratus samples by direct gamma–X spectrometry. This work was performed on a large spatio-temporal scale in order to

Direct gamma-X spectrometry is a suitable technique for quantifying low-level 129I activity, down to a few becquerels per kilogram, in environmental samples. Direct gamma-X spectrometry is a non-destructive technique that is rapid, which can be used

We developed a microfluidic device for the detection of bio-molecules. The active part of the device is a biofunctionalized interdigitated capacitive sensor. The microsystem consists of a sensor on silicon chip, a microfluidic channel formed by photo

The loss of alkanes from ionized aliphatic alkanes, alcohols, ketones, ethers or amines takes place by a 1,2-elimination involving a CC bond cleavage and the specific rearrangement of a hydrogen atom to the incipient radical. This reaction should nor

Reconsidering a recently introduced model of sequence-retrieving neural network, we introduce appropriate analogues of the well-known stabilities and show how these, together with two coupling parameters λ and ϑ, entirely control the dynamics in th

In this paper we study the dynamics of a simple spin-glass-like network, which should model the behaviour of the idotypic network of antibodies. Contrary to what happens in neural networks models, the synaptic strengths here are fixed (i.e. time inde

The specificity of biosensors is typically obtained by surface biofunctionalization, which enables the selective binding of biomolecules. This critical step is sensitive to the nature of materials and to the overall experimental conditions. Here, we
