H50 est un outil qui permet l’estimation de l’indice de productivité de divers peuplements purs équiennes, tant résineux que feuillus. Il intègre, au sein d’une interface simple d’utilisation, les modèles de productivité les plus récents développés par les scientifiques de Gembloux Agro-Bio Tech pour l’épicéa, le douglas, les mélèzes, le bouleau verruqueux, le merisier, l’érable sycomore, les chênes indigènes et le robinier. Les données nécessaires à son utilisation sont l’essence, une mesure de hauteur dominante et l’âge du peuplement au moment de la mesure. L’outil se présente sous la forme d’une feuille de calcul qui permet le traitement simultané de données issues de plusieurs peuplements de diverses essences. Il est également possible de directement y copier-coller des données issues de documents encodés sous Microsoft Access ou Excel par exemple. Cet outil a été développé avec l’appui des Services Publics de Wallonie (Département de la Nature et des Forêts, Accord-Cadre Recherche et Vulgarisation forestières). [less ▲]

High-resolution spectra of the Jovian aurora have been obtained with unprecedented spectral resolution in the 900-1190 Ì· window with the the Far Ultraviolet Spectroscopic Explorer (FUSE), using the 30"x30" LWRS aperture. All observed features belong to the H[SUB]2[/SUB] transitions from the B, C, B', D, B" and D' electronic states to the ground-state. These emissions are excited by inelastic collisions of the primary and secondary auroral electrons with H[SUB]2[/SUB] molecules. The relative intensity distribution of the observed lines depends on the rotational temperature of the emitting layer and self-absorption. Below 1100 Ì· , the transitions leading to the v" = 0, 1 and 2 levels of ground-state are partially or totally absorbed by H[SUB]2[/SUB], giving indications about the vibrational H[SUB]2[/SUB] distribution and overlying column. After a validation with an unabsorbed and a self-absorbed laboratory spectrum obtained in controlled conditions (100K, 300 eV), this study compares the observations and synthetic spectra, generated by a code including the B, C and B', D, B" and D' Rydberg states. The rotational and vibrational H[SUB]2[/SUB] temperatures are determined as well as the overlying H[SUB]2[/SUB] column. The combination of these parameters is used to determine the depth of the auroral energy deposition. This work is based on data obtained for the Guaranteed Time Team by the NASA-CNES-CSA FUSE mission operated by the Johns Hopkins University. French participants are supported by CNES. Financial support to U.S. participants has been provided by NASA contract NAS5-32985. [less ▲]

Recent theoretical and clinical contributions of elderly couple with alcoholic partner underlies the usefulness of pragmatic/interactive and semantic/symbolic approach of symptomatic situation. Particularly, alcohol-dependance is understood as related to developmental tasks, resources and bonds of life-cycle of elderly age. A psychotherapeutic process of elderly couple is narrated. This work is caractherized by the following phases: alcoholistic symptom control, individual and family story narration and renegociation and reshaping of couple spaces/times. Symptom gradual dissolution has permitted the relaunching of individual, couple and familial planning as a fundamental dimension for improving general quality life of elderly couple. [less ▲]

Objectives: This study aimed to create a new French version of the Hay and Jacoby habit-training procedure (1996; 1999) and apply it to novel populations to determine the degree to which habit and recollection were affected. Method: 36 young, 32 middle-aged, and 37 older adults participated in Experiment 1. 17 controls, 17 patients with amnestic Mild Cognitive Impairment (a-MCI), and 17 patients with Alzheimer's disease (AD) were involved in Experiment 2. Participants were assessed across a variety of demographic, neuropsychological and psychopathological variables (e.g., depressive affects, subjective experience of cognitive failures, interference sensitivity). The habit-training process-dissociation was used to explore the cognitive mechanisms underlying memory slips to separate the contribution of habit and recollection to memory performance. Results: The data show a very clear pattern of decreased recollection with age, F(2, 102) = 25.12, p < .001, η p2 = .197, and age-related neurological impairment, F(2, 48) = 39.22, p < .001, η p2 = .62, with intact use of habit-based memory. Additional evidence for the validity of the process estimates is provided by theoretically meaningful correlations between the process estimates and measures of attentional control (Stroop test: r = −0.40) and subjective memory complaint ( r = −0.45). Conclusions: Although likely not the same as familiarity, the data add to a growing literature suggesting that controlled forms of memory decline with age and in age-related neurological conditions (MCI and AD) whereas more automatic forms of memory (habit) remain intact. This research should improve understanding of memory complaints, preclinical and clinical dementia, and help target processes for rehabilitation.

The variables commonly used to describe the physical habitat of Atlantic salmon Salmo salar parr are average velocity, water depth, and substrate. A variety of micro- and mesohabitat models have been developed using these variables to assess habitat quality. However, Atlantic salmon parr live in highly turbulent streams and rivers in which intense fluctuations of water velocity occur. Laboratory experiments have shown that turbulence affects the behavior and energetics of fish. Nevertheless, habitat use in relation to the strong temporal variability of velocity in natural environments has rarely been studied. In this study, Atlantic salmon parr habitat was examined in relation to turbulence in the Patapedia River, Quebec. Rather than taking the usual approach of surveying a large population at one point in time, we used an intensive radiotelemetry tracking survey that focused on the habitat use of a few individual fish over an extended period. We analyzed habitat use in relation to several dynamic hydraulic variables. Our results revealed that under naturally turbulent conditions, the parr displayed high individual variability in their habitat use. Such heterogeneous use of habitat suggests that individuals are not constrained to a single habitat type. Furthermore, no differences were observed in habitat use among the four daily periods (dawn, day, dusk, and night) for individual parr. [less ▲]

The Multicolored Asian ladybeetle, Harmonia axyridis (Pallas), native to Asia, is an invasive species in many European and American countries. Initially introduced as a biological control agent against aphids and coccids in greenhouses, this alien species rapidly invaded many habitats such as forests, meadows, wetlands, and agricultural crops. This paper reviews the habitats (forests, crops, herbs, gardens and orchards) where H. axyridis has been observed, either during insect samplings or as part of Integrated Pest Management (IPM) programs. Studies have referenced H. axyridis on 106 plant taxa (35 arboreal species, 21 crop species, 27 herbaceous species, 11 ornamental species, and 12 orchard species) and have identified 89 plant- prey relationships (34 arboreal species, 16 crop species, 13 herbaceous species, 10 ornamental species, and 16 orchard species) in different countries. Harmonia axyridis is more abundant in forest areas, principally on Acer, Salix, Tilia and Quercus, than in agroecosystems. Some plant species, such as Urtica dioica L., which surround crops, contain large numbers of H. axyridis and could constitute important reserves of this alien species in advance of aphid invasions into crops. This review highlights the polyphagy and eurytopic aspect of H. axyridis. [less ▲]
