The purpose of this study was to investigate the imputation error and loss of reliability of direct genomic values (DGV) or genomically enhanced breeding values (GEBV) when using genotypes imputed from a 3,000-marker single nucleotide polymorphism (SNP) panel to a 50,000-marker SNP panel. Data consisted of genotypes of 15,966 European Holstein bulls from the combined EuroGenomics reference population. Genotypes with the low-density chip were created by erasing markers from 50,000-marker data. The studies were performed in the Nordic countries (Denmark, Finland, and Sweden) using a BLUP model for prediction of DGV and in France using a genomic marker-assisted selection approach for prediction of GEBV. Imputation in both studies was done using a combination of the DAGPHASE 1.1 and Beagle 2.1.3 software. Traits considered were protein yield, fertility, somatic cell count, and udder depth. Imputation of missing markers and prediction of breeding values were performed using 2 different reference populations in each country: either a national reference population or a combined EuroGenomics reference population. Validation for accuracy of imputation and genomic prediction was done based on national test data. Mean imputation error rates when using national reference animals was 5.5 and 3.9% in the Nordic countries and France, respectively, whereas imputation based on the EuroGenomics reference data set gave mean error rates of 4.0 and 2.1%, respectively. Prediction of GEBV based on genotypes imputed with a national reference data set gave an absolute loss of 0.05 in mean reliability of GEBV in the French study, whereas a loss of 0.03 was obtained for reliability of DGV in the Nordic study. When genotypes were imputed using the EuroGenomics reference, a loss of 0.02 in mean reliability of GEBV was detected in the French study, and a loss of 0.06 was observed for the mean reliability of DGV in the Nordic study. Consequently, the reliability of DGV using the imputed SNP data was 0.38 based on national reference data, and 0.48 based on EuroGenomics reference data in the Nordic validation, and the reliability of GEBV using the imputed SNP data was 0.41 based on national reference data, and 0.44 based on EuroGenomics reference data in the French validation.

Abstract. Science and Technology Studies (STS) scholars increasingly engage with science and technology (S&T) practitioners, scientists, engineers, and the like. The actual dynamics of these engagements differ from one project, framework or school to the next. However, to be reflexive, such engagements need at some point to deal with the ambiguous relationship between ‘engager’ and ‘engaged’. In an attempt to disambiguate these interactive ties, this chapter takes inspiration from Vinciane Despret, a philosopher of science who has provided ethnographic studies of ethologists. It specifically draws on two of Despret’s arguments about experiments on animals, more precisely rats, and the paradoxical relationships to which they give rise. By means of analogy, it then illustrates the similar ways in which we, as STS scholars, might happen to frame our interactions with S&T practitioners. It argues that any experimental research dispositif necessarily implies a specific relationship dynamic with whoever is engaged. This should not be considered as an obstacle, but instead an opportunity for learning—yet only if the dispositif is open to protest. The analysis here took shape during an engagement study conducted at a large-scale R&D center in Flanders, Belgium. It is informed by ongoing involvement in a broader research project (STIR) that aims at fostering reflexivity among S&T practitioners. [less ▲]

Unmanned Aerial Vehicle (UA V) structures are prone to damage during their service lives, caused by abominable environment factors. Its structural health monitoring can be effective in reducing maintenance costs and increasing service life to ensure safe and reliable operation. Two different damaged modal parameters based on modal analysis is discussed in this paper in order to develop an efficient damage identification technique for the UA V wing structures. Its structure modal is a natural attribute of structures, and apparently one of the most important parameters of structure dynamic characteristics. For a well designed aircraft wings structures, its modal pattern should be continuous without local mode. Therefore, based on the modal analysis utilizing numerical methods for a damaged structure, damages location and its extent can be revealed and damage level can be evaluated. All the numerical results illustrated these method are efficient and feasible for structural damage detection. And its can be utilized in structure [less ▲]

Climate change is now globally accepted. The 4th IPCC report, published in 2007, clearly indicates that this phenomenon is mostly the result of human activity. All parts of the globe are potentially at risk. There are no activity sectors that will be left untouched. Adaptation is therefore necessary. Since 2006, the European Commission has been looking at the climate change adaptation issue. It first held a consultation on the European Commission Green Paper “adapting to climate change in Europe - options for EU action”. This led to the publication of the White Paper « Adapting to climate change: towards a European framework for action ». In this document, the EC puts forward the idea of a compulsory Adaptation Strategy at Member State level. Several EU countries have already done so: Finland, United Kingdom and France. Belgium, through the National Climate Commission, adopted its « National Climate Strategy » in late 2010. The objective is to recommend an operational action plan by 2012. This action plan will be the result of a merger between the action plans of the three regions and the federal governments. The Flemish region launched a study to start the development process of their action plan in 2010; the Walloon region has followed with this study and the Brussels region and the Federal should launch their studies during this year (2011). This study enabled to draw a complete review – characteristics, current vulnerabilities, future vulnerabilities - of the Walloon region on seven topics: Agriculture, water, infrastructure/ spatial planning, health, energy, biodiversity and forests. An enlarged experts’ consultation identified key measures to implement in order for Wallonia to adapt to climate change. Chapter 1, « climate change adaptation in European regions », is a stock-taking exercise of adaptation strategies found in Europe in order to draw relevant lessons for this study. Chapter 2: « the climate futures of Wallonia”, is an analysis of the climate projection specifically carried out for this study. Those projections were used to identify Wallonia’s vulnerabilities. Chapter 3 « Wallonia’s vulnerabilities to Climate change” explores the seven themes Agriculture, water, infrastructure/ spatial planning, health, energy, biodiversity and forests to describe the current and future risks and to put forward a time-dependent and sectoral hierarchy of impacts. Chapter 4 « Wallonia’s adaptation to climate change » states the core principles used to define the adaptation choices as well as the proposed guidelines for each theme. Chapter 5 « towards an action plan » presents the adaptation measures by theme along with the first elements of an evaluation procedure. Finally, the appendices contain the operational documents: the full thematic sheets, the action plan, the strategic guideline paper and the transversal analysis and the supporting documents: maps, climate projections database and the benchmarks.

Adult male quail show high levels of aromatase activity in the preoptic area-hypothalamus (POA-HYP), which parallels the high number of aromatase-immunoreactive cells and elevated mRNA concentrations detected in this brain region by in situ hybridisation. Interestingly, females display considerably lower aromatase activity than males but have almost equal numbers of aromatase-immunoreactive cells and express similar levels of aromatase mRNA. Aromatase activity in the male POA-HYP can be rapidly regulated by calcium-dependent phosphorylations, in the absence of changes in enzyme concentration. In the present study, we investigated whether aromatase activity is differentially regulated by phosphorylations in males and females. A linear increase in accumulation of aromatisation products was observed in both sexes as a function of time but the rate of conversion was slower in females. Saturation analysis confirmed the lower maximum velocities (V(max) ) in females but indicated a similar affinity (K(m) ) in both sexes. Aromatase activity in females reacted differentially to manipulations of intracellular calcium. In particular, chelating calcium with ethylene glycol tetraacetic acid (EGTA) resulted in a larger increase of enzymatic activity in males than in females, especially in the presence of ATP. A differential reaction to kinase inhibitors was also observed between males and females (i.e. a larger increase in aromatase activity in females than in males after exposure to specific inhibitors). These findings suggest that the nature of aromatase is conserved between the sexes, although the control of its activity by calcium appears to be different. Additional characterizations of intracellular calcium in both sexes would therefore be appropriate to better understand aromatase regulation. [less ▲]

This consensus article reviews the various aspects of the non-pharmacological management of osteoporosis, including the effects of nutriments, physical exercise, lifestyle, fall prevention, and hip protectors. Vertebroplasty is also briefly reviewed. Non-pharmacological management of osteoporosis is a broad concept. It must be viewed as an essential part of the prevention of fractures from childhood through adulthood and the old age. The topic also includes surgical procedures for the treatment of peripheral and vertebral fractures and the post-fracture rehabilitation. The present document is the result of a consensus, based on a systematic review and a critical appraisal of the literature. Diets deficient in calcium, proteins or vitamin D impair skeletal integrity. The effect of other nutriments is less clear, although an excessive consumption of sodium, caffeine, or fibres exerts negative effects on calcium balance. The deleterious effects of tobacco, excessive alcohol consumption and a low BMI are well accepted. Physical activity is of primary importance to reach optimal peak bone mass but, if numerous studies have shown the beneficial effects of various types of exercise on bone mass, fracture data as an endpoint are scanty. Fall prevention strategies are especially efficient in the community setting, but less evidence is available about their effectiveness in preventing fall-related injuries and fractures. The efficacy of hip protectors remains controversial. This is also true for vertebroplasty and kyphoplasty. Several randomized controlled studies had reported a short-term advantage of vertebroplasty over medical treatment for pain relief, but these findings have been questioned by recent sham-controlled randomized clinical studies.
