There is worldwide increasing interest in producing ethanol from grains. Currently, maize is the main grain used in fuel ethanol production (particularly in the USA). However, in Western Europe and Canada, wheat is the main grain for ethanol plants. Barley, rye, sorghum or combinations of grains are also used. The process of ethanol production from grains generates by-products (distillers’ grains, solubles and/or gluten feed) with potential in livestock feed. Consequently, a better knowledge of chemical composition of these by-products is essential. The aim of the present study was to chemically characterise 14 batches of by-products (mainly from wheat, but also from barley and maize) purchased from some plants in Western Europe. Starch was almost completely removed by ethanol production process. Consequently, crude protein and fibre were concentrated in by-products with regard to grain value. Ratios of by-products to grain (wheat is reference) varied between 1.6 and 3.2 (protein), 1.6 and 2.7 (NDF) and 2.3 and 5.1(ADF). Furthermore, heat treatment used during the production process of dried distillers’ grains could cause destruction of important amounts of some amino acids, especially lysine (Maillard reactions). Ratios of lysine to crude protein varied among batches of byproducts and were particularly poor and unstable for distillers’ grains. In conclusion, chemical composition of European by-products of ethanol fuel produced from grains is variable. It is particularly important for wheat-based distillers’ grains. More information is needed about digestibility and availability of nutriments from these by-products. Particularly, lysine concentration and availability are probably one of the main concerns for nutritive value of by-products of ethanol fuel produced from grains. [less ▲]

Dans les Pays-Bas espagnols, morcelés par les revendications particularistes provinciales et bouleversés par d'incessantes guerres, se construit tout au long du XVIIe siècle une figure originale de la Vierge. "Reine de Guerre" et "Victorieuse", garante du pouvoir des Habsbourg et Patronne des villes, elle entre dans l'appareil symbolique que forgent les autorités pour promettre aux populations l'ordre espéré et fonder par la même occasion leur légitimité. L'A. repère et analyse les procédés qui ont contribué à définir ce rôle politique d'une Vierge puissante, triomphale et souveraine. Elle montre comment émerge cette fonction mariale tant dans la littérature pèlerine, dévotionnelle et théologique que dans les pratiques des communautés urbaines et de la Cour installée à Bruxelles [less ▲]

The present study was aimed to assess the effect of different levels of red worm (Perionyx excavatus) supplemented to the diet on growth performance and meat quality of broilers. An experiment was conducted on broilers (Ho x Luong Phuong) of 4 - 10 weeks old according to a completely randomized design with one unsupplemented group (control) and three supplemented groups corresponding to 3 worm levels in the diet, viz. 1%, 1.5%, and 2% on a dry matter basis. Results showed that the 2% worm supplemented group had the highest growth rate, higher than the control group (1925.3 kg/head vs 1822.6 kg/head at the age of 10 weeks) with P <0.05. Chicken in the supplemented groups had lower FCR. The dressing percentage, and leg meat in the 2% worm supplemented group were higher than those of the control group. The different levels of red worm supplementation did not significantly affect meat quality (pH, color, the rate of dehydration after storage and processing). [less ▲]

Within the iClass (Integrated Project 507922) and Enhanced Learning Experience and Knowledge Transfer (ELEKTRA; Specific Targeted Research or Innovation Project 027986) European projects, the author was requested to harness his pedagogical knowledge to the production of educational adaptive systems. The article identifies and documents the pitfalls of such interdisciplinary joint work. It suggests that the pedagogical added value of adaptive tools is more likely to be found in the support of human decision making regarding personalization strategies, autonomy development and metacognitive training than in the provision of highly technical automatic customization devices.

In this paper, I argue that the current legal framework as it stands offers sufficient means to refuse any effect to a marriage celebrated outside Belgium if it appears that it is a marriage of convenience. There has been much talk of strenghtening and fine tuning the legal framework in order to offer real protection against such foreign sham marriages. A thorough analysis of the law as it stands, and in particular of Article 27 of the Code of Privat International Law reveals that such fine tuning is by no means necessary. Article 27 properly applied already offers sufficient protection against such marriages. The analysis also reveals that in order to refuse effect to foreign marriages of convenience, it is not even necessary to call upon the doctrine of ordre public or of fraus legem, to which Article 27 refers. The application of these two doctrines appears to be very complex and will in most cases not be necessary. [less ▲]

We show that a remarkable compatibility exists between the results of a potential model with constituent quarks and the 1/Nc expansion mass formula for strange and nonstrange baryon resonances. Such compatibility brings support to the basic assumptions of relativistic quark models and sheds light on the physical content of the model-independent large Nc mass formula. Good agreement between both approaches is also found for heavy baryons, made of one heavy and two light quarks, in the ground state band. [less ▲]

We derive general analytic formulae for the matrix elements of the SU(6) generators for mixed symmetric $[N_c-1,1]$ spin-flavor states with an arbitrary number $N_c$ of quarks. They are relevant for baryon spectroscopy in the $1/N_c$ expansion method applied to light baryons and can be used to study excited states. In this way previous work on non-strange baryons can be extended to both non-strange and strange baryons. [less ▲]

En se focalisant sur les documents, l'interprétation et l'intersubjectivité, les technologies du Web 2.0 présentent de surprenantes analogies avec l'herméneutique philosophique, théorie de l'interprétation des textes. L'herméneutique philosophique fut obtenue par généralisation de l'herméneutique biblique par Dilthey au XIXe siècle pour être choisie comme alternative au positivisme dans la fondation de l'épistémologie et des méthodes des sciences de l'homme et de la société. Le présent article tente de montrer en quoi les technologies du Web 2.0 semblent plus adaptées aux besoins des sciences de l'homme et de la société que l'informatique traditionnelle, historiquement liée au positivisme logique. Des illustrations sont fournies en archéologie et en sociologie, deux disciplines qui furent des précurseurs dans l'utilisation de la mécanographie et des ordinateurs. [less ▲]

Bacteriocins from lactic acid bacteria: interest for food products biopreservation. Bacteriocins from lactic acid bacteria are low molecular weight antimicrobial peptides. They have inhibitory activity against the bacteria that are closed related to the producer strains and a narrow inhibitory spectrum. Nevertheless, most of them have activity against some food-born pathogenic bacteria as Listeria monocytogenes. The application of bacteriocins or bacteriocin producing lactic acid bacteria in food products to inhibit pathogenic or food-spoilage bacteria has then been suggested. This review focuses on the classification, structure, function, mode of action, biosynthesis and current food applications of bacteriocins from lactic acid bacteria. [less ▲]
