Veal calf industry economics
This paper provides an outline of the veal industry, its standing relative to other cattle farming enterprises, and its future prospects. In 2008 some 20 per cent of bovines slaughtered in the EU were for veal production and
about one-third of them were dairy calves. France, the Netherlands and Italy were Europe’s leading producers. Veal consumption in the European Union has been in steady decline since 1970. In 2008, it averaged 1.6 kg per capita,
with France and Italy being the largest consumers. Despite variations in farming systems and carcass characteristics from one country to another, veal production is an important outlet for milk replacer producers and provides
a market for their industrial dairy products. Regular changes in production factors such as the price of 8-day-old calves and milk replacers and their availability engender recurrent output fluctuations. Veal calf production
plays a major part in regulating the milk and bovine-meat markets: it has largely contributed to stemming dairy (and sometimes meat) surpluses. However, the context has changed since 2008 with no more surplus milk supply and reduced EU-support for incorporating skimmed milk powder into milk feeds. Therefore, the relative attractiveness of other productions using 8-day-old calves and the support policies for cattle farming as a whole will affect the future of the veal calf industry
Special report: silent disasters.
Disasters occur not only in war and conflict or after natural events, such as earthquakes or floods. In fact, the death of hundreds of thousands of children in Niger every year, often for treatable conditions, could just as well qualify as a disaster situation. A lack of funding for health care and health-care staff and user fee policies for health care in very poor or unstable settings challenge international agreements that make statements about the right to health and access to health care for all people. This paper argues that although sustainable development is important, today many are without essential health care and die in the silent disasters of hunger and poverty. In other words, the development of health care appears to be stalled for the sake of sustainability
A zero-thickness mortar/ interface formulation with application to fracture mechanics
A zero-thickness mortar/interface element formulation is briefly described and demonstrated. This element may be considered as an extension of traditional zero-thickness interface element, in order to represent material interfaces located in between subdomains with non-matching FE meshes. In the context of small strain analysis, these elements may be equipped with the same type of constitutive laws as traditional interface elements. Therefore, if friction or fracture-mechanics-based laws are adopted, mortar/interface elements may be used to represent frictional sliding or cracking following the lines (surfaces) along which they have been pre-inserted. Two basic verification examples of this type are presented, showing that the model can correctly represent uniform states of stress and deformation when connecting unmatched mesh subdomains

The Metallicity Gradient of the Old Galactic Bulge Population
Understanding the structure, formation and evolution of the Galactic Bulge
requires the proper determination of spatial metallicity gradients in both the
radial and vertical directions. RR Lyrae pulsators, known to be excellent
distance indicators, may hold the key to determining these gradients. Jurcsik &
Kovacs (1996) has shown that RR Lyrae light curves and the phase difference of
their Fourier decomposition, {\phi}31, can be used to estimate photometric
metallicities. The existence of galactic bulge metallicity gradients is a
currently debated topic that would help pinpoint the Galaxy's formation and
evolution. A recent study of the OGLE-III Galactic Bulge RR Lyrae Population by
Pietrukowicz et al. (2012) suggests that the spatial distribution is uniform.
We investigate how small a gradient would be detectable within the current S/N
levels of the present data set, given the random and systematic errors
associated with the derivation of a photometric metallicity versus spatial
position relationship.Comment: Proc. of the workshop "Asteroseismology of stellar populations in the

Meat safety as a tool of differentiation for retailers: Spanish and French examples of meat "supply chain brands"
The purpose of this article is to analyse how the health crises have contributed to increasing the segmentation of the supply of fresh and little-processed food products under the impetus of a reinforcement of regulations (affecting the supply chain as a whole) and of strategies adopted by the stakeholders. Indeed, since several food crises have strongly affected the production of animal food products, food safety has become one of the most important aspects of quality products for both consumers and retailers.
The authors carry out an empirical and comparative analysis of the reactions of two neighbouring countries (Spain and France) faced with major health crises caused by similar events: the emergence of BSE cases. A special focus is made on the initiatives taken privately by two French retail groups (Carrefour and Auchan) operating in both countries.
The analysis shows that retailers have developed systems of quality insurance developed in order to reduce uncertainty and to restore consumers’ confidence in the quality of the products they buy. These programmes of actions pave the way for policies of product differentiation. In a relatively different context from that of France, the two big French retail groups Carrefour and Auchan operating in Spain have developed similar approaches, which had not been the case in France.
The paper provide useful keys for a better understanding of the strategies of retailers (use of "supply chain brands" as tools of differentiation to ensure consumers’ loyalty, marketing communication) in a context of sharp competition and of relative dissatisfaction with respect to «minimum quality» standards. \u

A self optimizing synthetic organic reactor system using real-time in-line NMR spectroscopy
A configurable platform for synthetic chemistry incorporating an in-line benchtop NMR that is capable of monitoring and controlling organic reactions in real-time is presented. The platform is controlled via a modular LabView software control system for the hardware, NMR, data analysis and feedback optimization. Using this platform we report the real-time advanced structural characterization of reaction mixtures, including 19F, 13C, DEPT, 2D NMR spectroscopy (COSY, HSQC and 19F-COSY) for the first time. Finally, the potential of this technique is demonstrated through the optimization of a catalytic organic reaction in real-time, showing its applicability to self-optimizing systems using criteria such as stereoselectivity, multi-nuclear measurements or 2D correlations
A case for merging the ILP and DLP paradigms
The goal of this paper is to show that instruction level parallelism (ILP) and data-level parallelism (DLP) can be merged in a single architecture to execute vectorizable code at a performance level that can not be achieved using either paradigm on its own. We will show that the combination of the two techniques yields very high performance at a low cost and a low complexity. We will show that this architecture can reach a performance equivalent to a superscalar processor that sustained 10 instructions per cycle. We will see that the machine exploiting both types of parallelism improves upon the ILP-only machine by factors of 1.5-1.8. We also present a study on the scalability of both paradigms and show that, when we increase resources to reach a 16-issue machine, the advantage of the ILP+DLP machine over the ILP-only machine increases up to 2.0-3.45. While the peak achieved IPC for the ILP machine is 4, the ILP+DLP machine exceeds 10 instructions per cycle.Peer ReviewedPostprint (published version
