Future Remote Sensing data will include hyperspectral data more and more. This study frames in the preliminary studies to investigate the possibilities of these types of data. In this framework experimental flights were organised by VITO (Flemish Institute for Technological Research) and OSTC (Federal Office for Scientific, Technical and Cultural Affairs) on 13th of September 2002 with a Dornier 228 aircraft carrying the CASI/SWIR sensor, over different test sites in Belgium. The flights were done by NERC and VITO and framed in the STEREO-program of OSTC. This paper deals with the “Ghent test site” over a peri-urban area, and focuses on the 3D-geometry of these data. These hyperspectral data are characterised by relief-displacement and differences in relief. These displacements occur in a direction away from the centre of the image. For remotely sensed images this is the direction away from the flight-line. In the monoscopic analysis of such images, these displacements will disturb the interpretation, the classification and the mapping of the image information. These distortions can be compensated for with a DEM. Very often this DEM has to come from an external data source such as laser scanning or aerial photography. However, when hyperspectral data is taken stereoscopically, it is possible to derive a DEM from these stereoscopic hyperspectral images, and so avoiding the cost to purchase an external DEM. To obtain stereoscopic imagery, two images were taken with an overlap of 80% in the so called “metrical mode” i.e. with a high spatial resolution (0.5m) and a lower spectral resolution. A third image was taken in “spectral mode”, for interpretation issues. A DEM and orthophoto were generated from the hyperspectral data by means of digital photogrammetry. A number of Ground Control Points were collected for absolute orientation, by means of DGPS. The geometric precision of the DEM and orthophoto derived from these data are evaluated using DEM and orthophoto derived from aerial pictures on different scales. [less ▲]

Attempt to improve glucose control in type 2 diabetic patients by education about real-time glucose monitoring.

The effectiveness of a specific educational programme involving the use of a real-time glucose-sensor system (Guardian RT) to improve glucose control was investigated in patients with poorly controlled type 2 diabetes despite insulin therapy. Ten patients participated in a randomized crossover study comparing two 3-month periods, during which glucose levels were monitored by either self-monitoring of blood glucose (SMBG) alone or by Guardian RT (restricted to 1 week per month) in addition to SMBG. Only four of the enrolled patients completed both periods, while dropouts were mainly due to technical difficulties in using the device. All six patients who completed the first 3-month period showed a reduction in glycated haemoglobin (HbA(1c)) level whatever the mode of glucose monitoring (study effect). A further reduction in HbA(1c) level was observed in two of the three patients using the Guardian RT during the second period. Less frequent symptomatic hypoglycaemic episodes were noted during the 3-month period with the device in the four patients who completed both study periods. These limited, but promising, results of this pilot study appear to justify the initiation of a larger study to assess the use of a real-time glucose sensor in carefully selected patients with type 2 diabetes.

Attempted cultivation of Jatropha curcas L. in the lower Senegal river valley: story of a failure

With the objective of determining whether it would be possible to sustainably produce Jatropha curcas L. seeds on the marginal land situated close to the Senegal River, a 6-hectare pilot plantation was cultivated under drip irrigation between September 2007-November 2011, close to the village of Bokhol (Lat. 16°31’N, Long. 15°23’W). A series of tests were conducted on this plot, in order to identify the best cultivation methods for the area (date, density and method of planting, appropriate type of pruning, fertilisers to be applied, irrigation method, etc.). The average yields obtained at this site, after four years of cultivation (less than 500 kg.ha-1 of dry seed), using the best known production techniques, are significantly lower than anticipated, compared to the available figures for the irrigated cultivation of Jatropha in other parts of the world. The main causes of this failure are the plant’s limited useful vegetation period of six months per year, instead of twelve, and the scale of attacks by a soilborne vascular disease, which destroyed over 60% of the plantation within four years.

Attempts to Answer on the Origin of the High Nitrates Concentrations in Groundwaters of the Sourou Valley in Burkina Faso

Within the framework of the contract of Sourou River, a survey of the groundwater quality was performed through 7 campaigns of water sampling and analysis from 2006 till 2012. The water samples resulted from 23 drillings and 9 wells located in the Sourou Valley. Among the analyzed physico-chemical parameters, the nitrates concentrations ob- served were worrisome. Out of 32 water sources, 14 (44%) supplied a nitrates content superior to the WHO threshold value for drinking water (50 mg NO3/L). Very high concentrations, superior to 500 mg NO3/L with a peak in 860 mg/L, were observed. Given the important variations observed from a sampling point to another, a generalized contamination of the total aquifer was not possible. An individual diagnosis allowed to identify the possible causes of this degradation. Several sources of contamination, in connection with the anthropological activities, were observed near the water facili- ties (drillings/wells): animal and human wild defecation, presence of nontight latrines, solid waste, wastewater dis- charges. It is also advisable to wonder about the impact of the dynamite use for digging wells, this one being able to leave nitrates in the water. With regard to the intensive use of water from the strongly contaminated wells and drillings by the rural populations of Sourou, implementing protection areas within which would be eliminated the sources of contamination in addition to health education among populations could improve the situation. Care should also be taken in the use of nitrates explosives for digging new wells or drillings. [less ▲]

L'auteur "plaide pour un renouvellement organisé de la formation littéraire, pour une redisciplinarisation de l'enseignement de la littérature fondée sur les principes suivants : celui-ci devrait 1°) prendre en considération l'agrément ou le désagrément des apprentis lecteurs, 2°) guider la réflexion de ces derniers sur les facteurs potentiels de l'agrément et du désagrément, 3°) veiller à ce qu'ils acquièrent les connaissances nécessaires pour prêter aux oeuvres la qualité d'attention appropriée à l'intention artistique dont elles procèdent, et les nantir ainsi de critères qui leur permettent d'apprécier la valeur relative de ces oeuvres, 4°) proposer des parcours qui sensibilisent les enfants, d'abord, les adolescents, ensuite, aux vertus des écrits littéraires de donner à connaitre et la bibliothèque de l'humanité et l'homme singulier dans ses rapports avec le monde".
