Standard cow milk analysis as used for performance recording or milk pricing has been restricted for decades to fat and protein. Some countries added solids not fat, true protein, urea and lactose and most somatic cell counts (ICAR, 2009). However milk produced by a cow at a given moment under given environmental circumstances (e.g., management, feeding, and climate) is in itself a highly valuable source of information on the status of the animal, the quality of the product (milk), and the interaction environment-animal-product. The aim of this paper is to give a general overview of the current status of research on the interest, the challenges for recording but also the possible use of new phenotypes obtained from milk composition both for genetic improvement and other purposes. The paper will focus on dairy cows; most conclusions can obviously be extended to other milk producing animals [less ▲]

Rapeseed oil (RO) (a choice source of unsaturation-rich residues) was used in the present study to enrich anhydrous milk fat (AMF) with unsaturated C18 fatty acids (FA) (oleic, linoleic and linolenic acids). Comparatively, one “harder” fraction of AMF underwent the same reaction. The physico-chemical properties modifications induced by the reaction were followed. The compositional changes are reported in this first part and the consequent physical modifications are presented in a second part. [less ▲]

Chemical and/or physical modification of oils and fats are commonly used by food industry to widen their range of applications (1,2). Lipase-catalysed interesterification of anhydrous milk fat (AMF) and various vegetable oils is now a well documented procedure (3-7). The purpose of this technique is to produce original structured fats with properties different from a simple blending, that may be used as spreads or introduced into pastry. The new fats contain higher amounts of polyunsaturated fatty acids (PUFA) than butter, which provides health benefits (8,9). To our knowledge only a few authors associated AMF fractionation with blending and interesterification (10,11), although this combination may be used to increase the ratio of vegetable oil in blends and thus the PUFA content of the product. The compositional changes occurring during the lipase-catalysed interesterification of AMF/rapeseed oil (RO) and AMF stearin fraction (AMFSF)/RO blends were described in the first part of this study. In the present and second part are reported the resulting changes in physical properties, especially the melting behaviour through solid fat content (SFC), dropping point (DP) and fusion profiles by differential scanning calorimetry (DSC).

This paper focuses on the numerical modeling of nanoindentation tests. The first goal of this study is to collect essential material parameters and boundary conditions from the literature and to complete the data required to accurately model nanoindentation tests. The second goal of this study consists in validating the material parameters identified from macroscopic tensile tests of the body-centered cubic b phase of Ti-5553, a new generation of titanium alloy. This validation is performed looking at experimental and numerical nanoindentation curves obtained for different grain orientations. [less ▲]

In this report, pregnancies were obtained after extreme in vitro conditions- IVM/F/C of the donor embryos, - IVM, enucleation and artificial activation of the recipient oocytes, - nuclear transfer and - IVC of the reconstituted embryos. Even if the incidence of this syndrome is relatively low after embryo transfer, a possible increasing of its occurence cannot be excluded in correlation with an incomplete maturation of oocytes at the time of fertilization, smaller follicles giving non competent or partially competent oocytes. An other explanation of this syndrome resulting in the higher variation in newborn calves weight may be also partly explained by the in vitro conditions. The gametes and/or embryos may be submitted to media containing embryotoxic substances. In the other hand, gametes and/or embryos may not found embryotrophic substances in the media like growth factors... Owing to this phenomenon, strict recommendations should be followed concerning rigorous follow-up of pregnancies obtained after transfer of IVM/IVF/IVC or cloned embryos by pregnancy proteins (PSPB, PAG...) or hormone (placental lactogen, estrone sulfate) assay and, after birth, macroscopic examinations of newborn, cord and caroncules.

European policies have decided to reduce the greenhouse gas emissions of 20% and to reach 20% of renewable power production by 2020. Increasing wind power is one of the numerous solutions to reach these goals. However, this kind of energy production depends on the meteorological conditions and gives it an intermittent behaviour. The wind speed variations cause voltage and frequency fluctuations that are unacceptable for the power grid. Therefore, forecasting production will become essential with the aim of integrating this kind of energy production into the power grid. We have developed and compared two forecasting models which give as outputs the wind power production every 15 minutes over the Belgian territory: the first one uses the outputs from the global model GFS (available at a horizontal resolution of 0.5° every 3h) and the second one uses the regional climate model WRF-NMM (using a horizontal resolution of 4km). Both of these models predict the wind speed and transform wind speed into wind power production, using a power curve which depends on the wind turbines and their characteristics. The first model using the GFS outputs is not precise enough in space and time to correctly forecast the wind speed in punctual wind farms. That is why we apply some specific tunings on these forecasts. These tunings depend on the air density, the wind direction and the stability of the air mass. The second model using the WRF-NMM outputs runs over the Belgian territory. Initial conditions are forced by the GFS outputs at 0.5° and WRF computes a physical based spatio-temporal downscaling of the meteorological variables. The outputs have a spatial resolution of 4 km and a time resolution of 15 minutes. Some tunings are also needed to adjust the wind power forecasts by comparison to the wind power observations. We present here some results of both models and the interest of using a regional model for more precise wind power forecasting. [less ▲]

Accurate staging of non-Hodkin's lymphoma (NHL) is important for treatment management. We studied 53 patients (40 patients at initial diagnosis and 13 patients at disease recurrence) with histopathologically proven aggressive NHL to assess the value of whole-body FDG positron emission tomography (PET) as an imaging modality for staging and restaging NHL. All patients in this comparative analysis were submitted to clinical examination ; computed tomography (CT) and whole-body PET studies before starting the treatment. Results : whole-body FDG-PET seems to be more sensitive than clinical examination and CT imaging for detection of lymph node regions infiltrated by NHL : there were 98 abnormal peripheral lymph node regions senn by FDG-PET : 59 observed by clinical examination and 39 clinically undetected. The clinical examination showed 9 additional nodal lesions not seen by PET. Of 77 thoracic and abdominopelvic trated by CT. The CT studies showed 5 additional nodal lesions. Extranodal lymphomatous localisations in the liver (n=5), spleen (n=14), lungs (n=8), pleura (n=9), digestive tract (n=4), pelvis (n=2) and other sites (n=9) were identified by PET. Bone marrow infiltration demonstrated by PET was confirmed by biopsy in 6/10 patients, however known medullary invasion was not seen by PET imaging in 5 patients. Conclusion : whole-body FDG-PET without attenuation correction is an efficient, non-invasive method for staging and restaging aggressive NHL but marrow biopsy remains to be performed in addition to PET.
