Temperate and boreal forests undergo drastic functional changes in the springtime, shifting within a few weeks from net carbon (C) sources to net C sinks. Most of these changes are mediated by temperature. The autumn 2006-winter 2007 record warm period was followed by an exceptionally warm spring in Europe, making spring 2007 a good candidate for advances in the onset of the photosynthetically active period. An analysis of a decade of eddy covariance data from six European forests stands, which encompass a wide range of functional types (broadleaf evergreen, broadleaf deciduous, needleleaf evergreen) and a wide latitudinal band (from 44 degrees to 62 degrees N), revealed exceptional fluxes during spring 2007. Gross primary productivity (GPP) of spring 2007 was the maximum recorded in the decade examined for all sites but a Mediterranean evergreen forest (with a +40 to +130 gC m(-2) anomaly compared with the decadal mean over the January-May period). Total ecosystem respiration (TER) was also promoted during spring 2007, though less anomalous than GPP (with a +17 to +93 gC m(-2) anomaly over 5 months), leading to higher net uptake than the long-term mean at all sites (+12 to +79 gC m(-2) anomaly over 5 months). A correlative analysis relating springtime C fluxes to simple phenological indices suggested spring C uptake and temperatures to be related. The CASTANEA process-based model was used to disentangle the seasonality of climatic drivers (incoming radiation, air and soil temperatures) and biological drivers (canopy dynamics, thermal acclimation of photosynthesis to low temperatures) on spring C fluxes along the latitudinal gradient. A sensitivity analysis of model simulations evidenced the roles of (i) an exceptional early budburst combined with elevated air temperature in deciduous sites, and (ii) an early relief of winter thermal acclimation in coniferous sites for the promotion of 2007 spring assimilation.

Recycling waste building materials from construction and demolition (C&D) sites is increasingly investigated for economical and environmental reasons. Roller compacted concrete (RCC) is a special dry concrete mix; laid down and compacted like a soil, it is especially used for the construction of massive structures like dams or large horizontal surfaces like road foundation. In this paper, natural concrete slabs were cured in water, sea water, chloride solutions or sulphate solutions and then crushed to obtain virgin and contaminated (polluted) recycled aggregates. The aim of this research is the total replacement (100% coarse and fine) of natural aggregates (NA) by recycled concrete aggregates (RA) in the composition of a roller compacted concrete. The natural and recycled aggregates are characterised and compared. The mechanical properties and durability performances of concrete with contaminated RA are analysed. The experimental results showed that the polluted RA are much richer in chlorides than in sulphates and are leached if they are soaked in water. Significant differences were observed between the properties of original and new concrete and the results demonstrated the need of taking these contaminations into account. [less ▲]

Pregnancy-associated glycoproteins are powerful pregnancy markers in domestic cattle. These proteins are expressed in mono- and binucleate trophoblast cells from the first days of gestation until calving. Different molecules were identified as being expressed at various stages of pregnancy. However, up to date, their functions and activities during pregnancy were not yet established. Specific RIA tests were developed (classic and alternative RIA) and used to measure the concentration of these glycoproteins in blood during gestation and the postpartum period in cattle. In maternal blood, PAGs rise to detectable levels from the 24th-28th days after fertilization. A recent study indicated that PAGs can also be detected in milk samples. However, concentrations in milk are much lower when compared to those of plasma. [less ▲]

Negative thermal expansion (NTE) in tellurium based liquid alloys (GeTe 6 and GeTe 12) is analyzed through the atomic vibrational properties. Using neutron inelastic scattering, we show that the structural evolution resulting in the NTE is due to a gain of vibrational entropy that cancels out the Peierls distortion. In the NTE temperature range, these competing effects give rise to noticeable changes in the vibrational density of states spectra. Additional first principles molecular dynamics simulations emphasize the role of the temperature dependance of the Ge atomic environment in this mechanism. For comparison, we extended our study to Ge 2Sb 2Te 5 and Ge 1Sb 2Te 4 phase-change materials. [less ▲]

On the terrace of the site of Trou Al'Wesse, commun of Modave (province of Liège, Belgium), stratum 4b-δ, excavated in 2008, has been attributed to the Late Mesolithic. Ceramic sherds of La Hoguette type have been recovered from near the top of this Mesolithic context, which contains lithic artifacts, a charcoal lens, wild fauna including an aurochs astragalus with cutmarks, and a sawn red deer crown antler. LBK sherds of the type found in overlying stratum 4a, are absent in facies 4b-δ. This is the first time that La Hoguette sherds have been found instratified context associated with material that can be radiometrically dated, and also the first time that such sherds have been discovered south of the Meuse and Sambre in Belgium. New dates from this stratum contribute to placing these sherds and the other elements in chronological context. [less ▲]

The measurement of serum or plasma PAG concentrations is currently used as a specific method for pregnancy diagnosis in cattle. In this study, the correlation between five radioimmunoassay systems (RIA-497, RIA-706, RIA-780, RIA-809 and RIA-Pool) developed for measurement of PAG concentrations in ruminant species was investigated in plasma from pregnant Friesian Holstein females. Plasma PAG concentrations (ng/mL) measured by different RIA systems were significantly correlated between them ( 0.81; P<0.001). PAG concentrations increased significantly from Day 21 (n=27) to 30 (n=37) after AI by use of all PAG-RIA systems. From Day 30 to 80 after AI, lower PAG concentrations were observed when using the homologous system RIA-497. The addition of several proteinase inhibitors changed neither the non specific binding nor the B(0) binding to the tracer. Our results suggest that all tested PAG-RIA (RIA-497, RIA-706, RIA-780, RIA-809 and RIA-Pool) are highly correlated and can be useful to follow PAG concentrations in samples collected during the first trimester of gestation.

Belgium and Canada are definitely two very different countries in terms of geography, demographics, history. Politically, however, they share similar fundamental features: two distinct linguistic communities (and the minority in each case is French-speaking) live together in a federal system which is animated by political conflicts. Thus, Belgium and Canada are two interesting cases of multinational federations and it seems to be possible and above all insightful to study each case in light of the other. In this introduction, we first expose the rationale behind the comparative dialogue which is at the heart of this collective endeavor. Then, we briefly present each contribution and how they fit in the overall structure of the book. [less ▲]

How do citizens who grew up in a federal system understand federalism in their country? To answer this important question, in an experimental design, we asked 234 French-speaking Belgian university students to “draw Belgium”. No other guidelines were given. In addition to this request, the students were asked to fill in a 19-question questionnaire about their federal perceptions and preferences as well as political and socio-demographic indicators. In this article, we analyze the results of the questionnaire and reflect on the relationships between representations and perceptions of federalism in Belgium. [less ▲]
