Abstract

International audience; In the context of the ESA's SMOS and the ESA's BIOMASS space mission, the data processing algorithms require precise permittivity models of the different wood species. To develop the models, in situ sensors that could be easily deployed on the site dedicated to calibration/validation studies would be truly relevant. Microwave volume analysis can be a very useful tool to monitor material properties. There are very few commercial equipment dedicated to in-situ measurements and none of them is developed in order to leave the instrument on site for automatic measurements with specific constraints such as communication, low power consumption, frequency broadband, non-invasive measurement and cheap price. The main objective of the study presented is to develop an equipment to meet these challenges. In this article we will present the study that we conducted to design the broadband antennas needed by the device to perform efficient in situ measurements. Preliminary results on a concrete structure demonstrate the possibility to perform quality B scan despite the strict imposed specifications.

Abstract

This paper describes the feasibility study of a Ka-band transceiver specifically designed for small satellite and CubeSat operations. The transponder is conceived to ensure up to 100 Mbit s-1 data rate with a target power consumption of 20W and an overall volume of 1.5U, not including the antenna. To keep the cost as low as possible, commercial, off-the-shelf electronic components are used whenever possible. Exploiting a data communication interface like the one proposed, the small satellites market could be opened to new applications such as remote sensing, Earth observation and commercial telecommunications.

Abstract

Clinical research aiming at objectively identifying and characterizing diseases via clinical observations and biological and radiological findings is a critical initial research step when establishing objective diagnostic criteria and treatments. Failure to first define such diagnostic criteria may lead research on pathogenesis and etiology to serious confounding biases and erroneous medical interpretations. This is particularly the case for electrohypersensitivity (EHS) and more particularly for the so-called "provocation tests", which do not investigate the causal origin of EHS but rather the EHS-associated particular environmental intolerance state with hypersensitivity to man-made electromagnetic fields (EMF). However, because those tests depend on multiple EMF-associated physical and biological parameters and have been conducted in patients without having first defined EHS objectively and/or endpoints adequately, they cannot presently be considered to be valid pathogenesis research methodologies. Consequently, the negative results obtained by these tests do not preclude a role of EMF exposure as a symptomatic trigger in EHS patients. Moreover, there is no proof that EHS symptoms or EHS itself are caused by psychosomatic or nocebo effects. This international consensus report pleads for the acknowledgement of EHS as a distinct neuropathological disorder and for its inclusion in the WHO International Classification of Diseases.
