La répartition en Belgique et au Grand-Duché de Luxembourg a été établie pour 54 espèces d'Elatérides appartenant à 10 sous-familles différentes : Agrypninae, Ampedinae, Conoferinae, Physorhininae, Hypnoïdinae, Negastriinae, Cardiophorinae, Melanotinae, Pomachiliinae et Athoïnae, sur base de matériaux de collection accumulés depuis 1850. Sur ces 54 espèces, treize montrent une distribution en Belgique plus ou moins ubiquiste et vingt sont rares, très localisées ou en voie de disparition. Onze espèces sont localisées dans le sud de la Belgique et au Luxembourg (Ampedus cinnabarinus, A. elegantulus, A. nigroflavus, Cardiophorus rufipes, Idolus picipennis, Cidnopus parvulus, Limonius aeneoniger, Hypnoïdus riparius, Zorochrus dermestoïdes, Z. flavipes et Quasimus minutissimus) tandis que quatre espèces sont au contraire principalement localisées dans le nord de la Belgique (Ampedus sanguinolentus, Cardiophorus ruficollis, Melanotus niger, Negastrius pulchellus). Deux espèces semblent en voie d'expansion : l'une probablement d'origine orientale (Ampedus sanguineus), l'autre probablement d'origine atlantique (Athous difformis). Enfin, la distribution de trois espèces de Cardiophorinae semble liée à la présence de biotopes sablonneux. [less ▲]

The use of PIXE allowed for a simultaneous determination of serum copper (Cu), zinc (Zn), selenium (Se) and bromine (Br), in various groups of patients with hematologic malignancies. In 78 patients with acute nonlymphocytic leukemia, it was observed that (1) serum Se was significantly lower than in healthy controls and correlated inversely with the tumor burden; (2) serum bromine was normal at diagnosis but dropped dramatically after intensive chemotherapy, before recovering progressively over a period of months; and (3) pretreatment serum copper and zinc were significant prognotic factors of the chance to achieve a complete remission. In 50 patients with chronic lymphocytic leukemia, it was observed that (1) serum Cu and Cu/Zn ratio were useful indices of the disease activity, which were independent of a nonspecific acute phase reaction; and (2) Zn deficiency could contribute to immune dysfunction. In 119 patients with myeloproliferative disorders or myelodysplasic syndromes, serum Cu and Zn levels were mostly dependent on nonspecific factors, such as age and inflammation. [less ▲]

The subsector represents a meaningful and manageable division specially adapted to comprehensive investigation on agro-industrial systems. The food subsector studies permits an integrated approach of problems linked with production development in Third World countries. The author of this paper, after having determined the concepts in relation with the subsector from theoretical point of vue presents the generaI characteristics of successful agro-industrial systems in developing countries and proposes a methodology to appreciate the competitivity of subsectors.

The growing use of remote sensed imagery and D.E.M., for instance, in land planning and environmental studies is in favour of G.I.S. raster-based. Nevertheless, the availability and the selectivity of vector formated data force their joint processing. This communication deals with techniques allowing simultaneous handling of vector information and raster imagery, according to raster, vector, or hybrid algorithms. The vector to raster technology used by the current display devices makes the implementation of such procedures easier. Exemples of different classes of vector representation are used jointly with remote sensed images to illustrate the items under discussion. [less ▲]

It had long been considered that intensive agriculture was the only source of groundwater and river pollution. This study is about an area with low intensity agriculture. It is based on field measurements of several soil profiles in a small watershed. The soil profiles show that important nitrogen losses (up to 100 kg N/ha) occur during winter, mainly in maize and potato fields. This paper also draws the attention to soil and water pollution resulting from large quantities of poorly used manure. [less ▲]
