L’augmentation de la surface des parcelles et par là-même l’augmentation du facteur pente (L.S. moyen + 13%) et, accessoirement, la diminution de surfaces semées perpendiculairement à la pente (P moyen + 1%) aggravent le risque érosif. Cette augmentation du risque érosif, le remembrement pourrait y remédier. En effet, dans les trois premiers quartiers du remembrement étudié, l’augmentation du risque érosif est due à la fois à l’agrandissement des parcelles et au nouveau redécoupage parcellaire qui a favorisé le semis parallèle à la pente. Dans le quatrième quartier par contre, l’augmentation du risque érosif résultant de l’agrandissement des parcelles a été compensée par une réduction du semis parallèle à la pente. Il apparaît donc que le nouveau découpage parcellaire, en favorisant le semis perpendiculaire à la pente, peut annuler l’augmentation du risque érosif résultant de l’agrandissement des parcelles. De plus, les nouveaux chemins sont susceptibles de réduire l’érosion tant par leur tracé lui-même que par leur incidence sur le nouveau parcellaire. Quant aux inconvénients érosifs résultant de ces nouveaux chemins ils peuvent être évités par des mesures adéquates. Il va de soi que les remembrements ne sont et ni ne peuvent être conçus exclusivement en vue de lutter contre l’érosion des sols. Néanmoins, si dans la conception des remembrements, il était tenu compte de la possibilité de lutter contre l’érosion, il ne fait aucun doute que leur réalisation pourrait conduire à une diminution sensible du risque érosif alors qu’actuellement ils contribuent à augmenter celle-ci. La présente note ne vise pas à apporter de solutions aux problèmes posés par l’érosion dans les remembrements. Elle se donne simplement pour but d’attirer l’attention sur l’importance du phénomène et ses conséquences. Jusqu’à présent, en effet, il semble qu’on s’est montré, par le passé, insuffisamment attentif à ces problèmes alors que l’érosion est responsable d’une perte de rendement moyenne de l’ordre de 3 à 5% (A. Bollinne et al., 1978). [less ▲]

Remodelage chirurgical du ventricule gauche par endoventriculoplastie: observation clinique

A case of dilated ischemic cardiomyopathy, with severely impaired left ventricular systolic function, treated by endoventriculoplasty and CABG, is reported. The authors discuss the modern concepts regarding the surgical treatment of large anterior asynergic scars following occlusion of the LAD. Since there are more similarities between akinesia and dyskinesia than previously thought, the endoventriculoplasty of DOR may constitute a new way to surgically remodel the left ventricle in dilated cardiomyopathies with large anterior akinesia. This surgery significantly improves the ventricular function and the overall patients' prognosis at short and mid term follow up. [less ▲]

X-ray fluorescence (XRF) is a nondestructive, multielemental, fast and cost-effective analysis technique. It can be applied in a nonvacuum environment directly on the samples without any preparation. As archaeological and historical objects are often unique and may not be easily movable, a mobile XRF detector system allowing in situ analysis is ideally suited for archaeometric applications. A mobile system was designed and built at the IPNAS laboratory to provide such analyses. The system includes an industrial grade x-ray generator which supplies the primary x-ray beam, an air-cooled silicon rift Detector detector (SDD) with a 5-mm(2) active area. The data acquisition system measures the energy and the intensity of the secondary fluorescence x-rays. The detector signal is amplified and analyzed by a multichannel recorder coupled to a microcomputer running JavaSpectre which visualizes and analyzes spectra obtained from the detector. The detection head, containing the detector, the x-ray tube and its power supply, are fixed on a movable platform allowing independent vertical and horizontal movement. All displacements are controlled by a hand-held personal digital assistant (PDA) (Palm) which exchanges data with microcontrollers embedded in the system providing a very precise positioning of the detector over a surface of many square meters. This system control, as well as a typical application of this XRF spectrometer for analyzing pigment composition of a wall painting, will be described. Copyright (C) 2008 John Wiley & Sons, Ltd.

One of the key geographical developments over the last two centuries has been that of urbanisation. In recent years this has exploded globally, particularly in developing countries. It is essential for governments, planners and researchers in geography and allied fields to understand this process and the main way of being able to do this is to accurately map these changes. The main method of this mapping is Remote Sensing.This up-to-date analysis of the area looks at a wide range of methodologies currently being used to produce and analyse remotely sensed data of urban areas. The authors examine the various techniques used to extract information from digital, multispectral images of urban areas. Donnay and Barnsley then go on to look at the identification of urban forms, the delineation of agglomerations and the development of urban morphology, considering the analysis of integrated data sets and surface models and going on to look at the estimation of human population levels.

The Kou watershed is a geographical space having important water resources, whose are used between: drinking water supply of Bobo-Dioulasso city (Burkina-Faso’s second most important city) and surrounding localities; agriculture through very important irrigated surfaces; industry; fauna and flora preservation, through a minimal sanitary debit guaranteed. Since some decades, one observes more and more increased pressure on Kou water resources. From an agricultural point of view, a comparative visual observation of irrigated surfaces during the years 1980 and during years 2000 shows an increase of surfaces. It would be then appropriate to establish a potential of irrigation of the set of available water resources in order to estimate maximal irrigable surfaces by water resources. Thus, this study has for goal the evaluation of Kou watershed irrigated zones surface, with the help of remote sensing. In order to facilitate irrigated zones detection, the study will focused on the period between January and June, where all cultures are irrigated with Kou watershed surface water and/or groundwater. The chosen methodology is images classification in order to extract irrigated zones surface. We had for this study a set of images and various data: Landsat-4 TM, Landsat-5 TM, Landsat-7 ETM+, SPOT 5, aerial views, agro meteorological data, cartographic data (GIS), data investigation reports, etc. Because of images various origins, we conducted images pretreatment that essentially consisted in image reflectance calibration. This operation appears to be indispensable when working with images from coming different sensors. Classification methods that we used are: a maximum likelihood classification, then a decision tree classification applied to images for which vegetation index (NDVI) has been calculated. The later classification method has been introduced in order to permit a better discrimination between natural vegetation and crops which can often react in similar spectral ranges. This method is based on threshold detection of vegetation classes. Classification methods used allowed us to estimate until a certain point irrigated surfaces, without having, however, a finer information. With 30 m spatial resolution images covering a survey zone with "reduced" to "mean" agricultural lands size, it is sometimes enough difficult to discern natural vegetation pixels from crop pixels. So, we should have considered mixed classes of pixels that strongly skewed our final results. The overall accuracy of our classifications are between 70% and 90%, with Kappa coefficients between 0.4 and 0.85. These Kappa coefficients our results between "tolerable" and "good". However, our evaluations seem to be near enough of those gotten by the means of hydro agricultural inventories led on the same zone. The committed mistakes remain in an interval of +/-20%. [less ▲]
