Chapter 5 reports the results of testing the proposed prodedures for harmonizing estimates of indicators for six of the seven essential features of forest biodiversity. Twenty indicators were tested using data from the common database. In general, positive results were obtained for forest categories, forest structure, forest age, deadwood, and naturalness; the results were less positive for ground vegetation because of the considerable differences in definitions and data acquisition methods. Of importance is, that the test focused on assessing harmonization procedures rather than on producing comprehensive estimates for particular countries or forest categories. [less ▲]

We are concerned with a problem in which a firm or franchise enters a market by locating new facilities where there are existing facilities belonging to a competitor. The firm aims at finding the location and attractiveness of each facility to be opened so as to maximize its profit. The competitor, on the other hand, can react by adjusting the attractiveness of its existing facilities with the objective of maximizing its own profit. The demand is assumed to be aggregated at certain points in the plane and the facilities of the firm can be located at predetermined candidate sites. We employ Huff's gravity-based rule in modeling the behavior of the customers where the fraction of customers at a demand point that visit a certain facility is proportional to the facility attractiveness and inversely proportional to the distance between the facility site and demand point. We formulate a bilevel mixed-integer nonlinear programming model where the firm entering the market is the leader and the competitor is the follower. In order to find the optimal solution of this model, we convert it into an equivalent one-level mixed-integer nonlinear program so that it can be solved by global optimization methods. Apart from reporting computational results obtained on a set of randomly generated instances, we also compute the benefit the leader firm derives from anticipating the competitor's reaction of adjusting the attractiveness levels of its facilities. The results on the test instances indicate that the benefit is 58.33% on the average. [less ▲]

Because of the PK-Weir geometric specificities, its hydraulic capacity remains difficult to predict without using experimental techniques. A 1D numerical model of the flow over a PK-Weir has been developed at the Research unit HACH at the University of Liege. It is based on a 1D modeling of the inlet and the outlet separately, with a single upstream reservoir and interactions between both flows by exchange of mass and momentum along the lateral crest. The comparison of the numerical results with various experimental data showed the ability of the numerical model to predict with reasonable accuracy the release capacity of a PK-Weir, whatever its geometry. The tests of the solver enable to highlight the significant influence of the inlet and outlet width on the weir release capacity. They also suggest that improvements of the numerical model may lie in the evaluation of the discharge coefficient of the lateral crest. [less ▲]

Coordinating abilities of 4R-1,2,4-triazole derivatives (R = glycine ethyl ester (L1), glycine (L2), diethylamino malonate (L3), methionine (L4) and diethyl aminomethylphosphonate (L5)) towards ZnII ions have been studied in solution, in solid state and versus three zinc-b-lactamases. The crystal structure of [Zn3(L4)6(H2O)6] (6) is described; it is the first crystal structure involving a 1,2,4-triazole functionalized methionine. It forms a trinuclear complex with central zinc octahedrally coordinated by only L4, whereas terminal zinc ions coordination sphere is completed by three water molecules. L4 exhibits a dual functionality of a bridging bidentate ligand as well as an anion. A dense hydrogen bonding network connects these trinuclear entity into a 3D supramolecular network. The ZnII ions in 6 are held at equidistance (3.848 Å) which coincidently matches with the corresponding Zn Zn distance in the binuclear zinc enzyme from Bacillus cereus (3.848 and 4.365 Å). Among L1–L5 screened for b-lactamase assay, L4 shows modest inhibition for BcII enzyme. [less ▲]

Several studies using the mirror-reading paradigm have shown that procedural learning and repetition priming may be preserved in the early stages of Alzheimer's disease (AD) (e.g., Deweer et al., 1994). According to the classical interpretation, improved reading time for repeated words is sustained by a repetition priming effect, while procedural learning is demonstrated when this improvement is also observed for new words. Following Masson (1986), the hypothesis tested in the present study was that improved reading of new words could also be due to a repetition priming effect rather than to the acquisition of a mirror-reading skill. Indeed, because the same letters are presented throughout the task, a repetition priming effect for the letters could suffice to explain the improvement in performance. To test this hypothesis, we administered to 30 healthy young and elderly subjects and to 30 AD patients a new mirror-reading task in two phases: an acquisition phase comprising pseudo-words constructed with one part of the alphabet, and a test phase in which both pseudo-words constructed with the same part of the alphabet and pseudo-words constructed with another part of the alphabet were presented. If the new pseudo-words composed with repeated letters were read faster, it would reflect a repetition priming effect; if pseudo-words composed of ‘new’ letters were read faster, it would reflect a procedural learning effect. The results show comparable repetition priming effects in AD patients and in healthy elderly subjects, whereas only healthy subjects showed a procedural learning effect. These results suggest, contrary to previous studies, that the learning of a new perceptual skill may not always be preserved in AD. [less ▲]

Antigen expression and purification are laborious, time consuming and frequently difficult steps in the process of antibody production. In the present study, we developed a method avoiding these two steps. This method relies on the injection of histocompatible living cells stably expressing the antigen as a cell surface type II transmembrane fusion protein. A vector, nicknamed pCD1-CD134L, was constructed to express the antigen fused at the carboxyterminal end of the human CD134 ligand (CD134L) type II transmembrane protein on the surface of eucaryotic cells. This vector was shown to induce cell surface expression of epitopes from human c-Myc (soluble protein), uterogloblin-related protein 1 (secreted protein) and CD94 (type II transmembrane protein). Using this vector, we developed a method to produce antibodies without antigen production. The flowchart of this method is as follows: (i) cloning of the antigen in the pCD1-CD134L vector; (ii) production of a histocompatible cell line stably expressing the CD134L-antigen fusion protein; (iii) testing for cell surface expression of the fusion protein by targeting the CD134L carrier; and (iv) prime-boost immunisation with living cells expressing the fusion protein. This method was successfully used for production of polyclonal antibodies raised against Ixodes ricinus calreticulin (secreted protein) in mice and for production of monoclonal antibodies raised against an epitope of Vaccinia virus A56 (type I transmembrane protein) protein in rat. The present study is the first to demonstrate the use of a type II transmembrane protein as a carrier for cell surface display of antigens. [less ▲]

Dans le cadre du projet Interreg Grande Région "REGIOWOOD" et plus particulièrement de l'action s'intéressant à la mobilisation des ressources ligneuses en petite forêt privée, une étude a été menée sur le territoire de la commune de Gouvy avec l'objectif de caractériser les ressources forestières, leur disponibilité et les freins à leur mobilisation. Cette étude trouve sa justification dans la nécessité de disposer d'informations objectives utiles pour mener à bien toute démarche d'amélioration de la mobilisation des ressources en bois. L'estimation de la ressource en bois a été réalisée au niveau communal (paragraphe 1) via l'analyse des données cadastrales (paragraphe 2) et la réalisation d'un inventaire spécifique des ressources (paragraphe 3). Les multiples données qui ont pu être rassemblées grâce à un inventaire par échantillonnage ont été complétées par des chiffres résultant d'une évaluation par simulation de l'évolution probable, et sous certaines conditions, du capital ligneux (épicéa commun) au cours des 5 et 10 prochaines années (paragraphe 4). L'exploitation de ces informations doit s'accompagner d'un dialogue et d'une concertation avec les propriétaires de la ressource (paragraphe 5) avant de proposer les démarches les plus adéquates à mener en matière de mobilisation et de valorisation de leurs biens (paragraphe 6).

Jean-Jacques Rousseau est né avec la conscience de son altérité : fils d’horloger, citoyen de Genève, il se sent dès son plus jeune âge différent du monde qui l’entoure. Par sa « réforme » au début des années 1750, il transformera officiellement cette altérité en faire-valoir. Pourtant, quand résonne le glas de la condamnation de ses œuvres (Émile et le Contrat social) en 1762, l’homme jusque-là différent, se sent étranger, incompris, seul contre tous, comme en témoigne sa correspondance. Cet article se donne pour objectif d’étudier ce sentiment d’altérité et d’étrangeté à travers la correspondance personnelle de Jean-Jacques Rousseau de 1762 à 1765 (soit de la condamnation de l’Émile et du Contrat social jusqu'au départ pour l’Angleterre chez David Hume).

La crise financière mondiale qui a éclaté en 2008 et les effets désastreux qu’elle a occasionnés sur le secteur minier en RDC (qui avait été placé au centre des politiques de croissance et de lutte contre la pauvreté) posent avec encore plus d’acuité la question de la diversification de la structure économique dans une province comme le Katanga. Au problème de la vulnérabilité d’un tel modèle de croissance s’ajoute le constat qui est fait dans cette étude du manque d’effet d’entrainement de l’activité des grands groupes miniers sur le reste de l’économie locale, en termes de développement des capacités productives et de création d’emplois.

Methane (CH4) is one of the most abundant greenhouse gases in the Earth’s atmosphere, with current mean volume mixing ratio close to 1800 ppb. Since methane has a global warming potential of 25 (100-yr horizon) and an atmospheric lifetime of 12 years, the Kyoto Protocol has included it among the species to be regulated to limit global warming. Anthropogenic sources of methane are mainly energy production (coal and leaks) and agriculture while main natural sources are swamps and biomass waste. The main sink of methane is oxidation in the troposphere, primarily by reaction with the hydroxyl radical. Methane trends have exhibited significant changes during the last twenty-five years. For instance, long-term monitoring of its vertical total column above the high-altitude station of the Jungfraujoch (46.5°N, 8°E, 3580 m asl) has indeed allowed to derive column changes ranging from +0.72% in 1987-1988 to +0.14% in 1999-2000 (Zander et al., 2002), relative to 1988 and 2000, respectively. More recently and for the same site, Duchatelet et al. (2010) have even reported a significant slowdown of -0.02%/yr between years 2000 and 2005. This study also showed that since then, CH4 is on the rise again, at a rate close to +0.30%/yr. While the numbers reported here above have been derived from the Fourier Transform Infrared (FTIR) data set starting in 1984, earlier pioneering observations have been collected at the Jungfraujoch since 1950, using grating spectrometers. During the 1958-1975 period, the main objectives has been the study of the solar photosphere in the visible and the near infrared and the publication of high-resolution solar atlases. From 1976 to 1989, narrow-band IR solar absorption observations achieving a spectral resolution of about 0.02 cm-1 have been recorded with the high-performance double-pass grating spectrometer. Analysis of these historical spectra provides a unique opportunity to extend the Jungfraujoch’s total column time series of important atmospheric gases, including methane, by nearly 10 years. The aim of this contribution is to present the inversion strategy adopted to derive CH4 from the grating spectra, using the SFIT-2 algorithm (v3.91) We will evaluate the impact of resolution, spectroscopic parameters (from the EU HYMN project -see www.knmi.nl/samen/hymn-, and from HITRAN 2004), atmospheric pressure and temperature profiles on the error budget. The 1976-1989 total column time series produced will be presented and critically discussed. In particular, we will identify and correct for possible biases between double-pass grating spectrometer measurements and more recent FTIR total columns. The harmonized and consolidated time series will be investigated to characterize the long-term trend of methane for the 1976-2010 time period. Comparisons with synthetic data produced by the CHASER 3-dimensional chemical transport model will also be presented and analyzed. [less ▲]

The efficacy of grafting materials for alveolar bone regeneration procedures has been repeatedly corroborated by clinical and scientific evidence. Although an ever growing number of biomaterials are available on the market, the origins, material characteristics, bioactivity and osteoconductive properties of these products are not always known by clinicians, hence often hampering an adequate product selection. The purpose of this contribution was to provide an overview of five different types of osteoconductive grafting materials frequently used in dentistry (Bio-Oss®, Cerasorb M™, Bone Ceramic®, Natix®, Genos®) and to summarize their physico-chemical and morphological characteristics at the macro- and micro-scale. Furthermore, the influence of these properties on the in vivo behaviour of these biomaterials is discussed. The results of this study are presented as data sheets, which may prove helpful for clinicians in the design of their treatment strategies. [less ▲]
