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 ▲]

à quoi ressemble la Voie lactée dans l'ultraviolet ? Que cachent les nuages de poussière qui voilent des parties entières du ciel ? Avec la découverte des ondes électromagnétiques (ondes radio, ultraviolet, infrarouge, rayons X, gamma), le ciel s'est teinté de nouvelles couleurs, changeant totalement d'aspect, jusqu'à révéler des phénomènes d'une violence insoupçonnée. Les télescopes du monde entier obtiennent maintenant des images d'un univers inconnu que l'auteur nous apprend à comprendre. Riche en anecdotes parfois cocasses sur des découvertes qui doivent parfois au hasard ou Ãà la persévérance obstinée de chercheurs, le livre invite le lecteur à découvrir un monde invisible à l'oeil. Des mystérieux quasars au rayonnement cosmologique, c'est à un voyage au fil de ce nouvel arc-en-ciel que nous convie l'auteur. [less ▲]

In Southern High Katanga, the ferruginous formations such as iron duricrusts and stone lines with lateritic nodules show a diversity as broad as in Western Africa. Bauxites are nevertheless almost absent proving that, here, aluminium does not contribute to the genesis of duricrust, leaving iron as the only responsible. Among that wide diversity, the indurated sands form a special case because of their dual origin. Because of a large porosity favouring a fast iron penetration and fixation, some of the sandy concretions or duricrusts may have a short history and some of them may even be very recent. Nevertheless the others have a genesis that fits in with the general longer scheme. The most frequent type of laterite crust is also the most complex one. Its facies is both nodular and vermicular. Several agents and climatic phases are involved in its formation : • A first planation surface with wide-open valleys where the water table lies near the surface induces favourable circumstances for the next step; • In such circumstances, nodules are shaped in the mottled soil horizon. One exceptionally well-preserved site evidences the proximity between mottles (the nodules to be) and water table level at the end of the dry season; • A revival of erosion enhances river down cutting which in turn lowers the water table so that termites can reach the mottled horizon; • Nodules are mechanically concentrated by elimination of the non-indurated zones (relative accumulation): within the soil, by termites (on shaly rocks), at the surface by run off (often, on sandy rocks, unfavourable to termites activity); X • Finally the ran off extends to both types of rock and denudes the indurated zone; • A ferruginous coating forms on different substrates : upper laterite surface, internal joints, termite galleries as well as on any gravel at the soil surface. The coating lies unbroken from one object to the other but the outer surface is frequently eroded. The superficial coating could be a rock varnish formed by bacteria during a desertic period. The coating of galleries partly inhibits bioturbation because they collapse no more. The network of the strengthened galleries constitutes an internal skeleton reinforcing the laterite mantle; • With the return of a less severe climate, termites from below the laterite mantle again bring up material. The resulting upper fine deposit often exceeds 2 meter. All those processes imply important climatic variations : • A steppe vegetation with a scanty grass cover favouring run off and planation; • A relatively arid climate for the coatings formation; • A contrasted seasonal regime, not so different from the present day climate (six months dry season) for vertical erosion and intense termite activity. The weathering of rocky materials except for the iron impregnated ones (nodules, ferricretes and so on) requires a humid climate. This is happening nowadays but the more humid Quaternary phases were more effective in that respect. The characteristics of the outer coatings (thickness, colour, conservation state of the included quartz grains) allow us to identify four levels of ferricrete. Their succession is confirmed by the relative position of the coatings between them and by the correlated continental deposits. Because of their coatings, all those ferricretes are dated back to the Tertiary (because of the desertic climate needed for the formation of the rock varnish). Their levels overlook the Quaternary river terraces. The oldest ferricrete is quite different from the others. It shows neither nodules nor termite galleries. Its facies is thus very different from the nodular/vermiform of the three younger ones. It shows three facies, sometimes superimposed : pisolithic, massive or breccia-like. Moreover, the ferricrete of the corresponding level in West Africa contains bauxite. Its genesis is the result of a very different sequence of processes, some aggressive and linked to a humid climate with a great supply of iron and others resulting from more arid conditions producing the thick pisolith coatings. Ferruginous stone-lines present a wider variety of concretions than duricrast. Their upper part is the result of a concentration mainly by run off that occurred during several periods of the Quaternary. Cover loam is each time built up again by the termites from weathered rocks below the stone-line. The same phenomenon is seen on ferricretes. The soil profile where ferruginous formations can be seen consists of horizons of different ages. Weathering of saprolite and soil lifting are still active nowadays. Whereas some stone-line profiles are renewed at each Quaternary dry phase, the ferricrete profiles are build up during a long period of time extending from the Tertiary till now. A new definition of iron duricrast is proposed that is not based on weathering in depth or on the presence of aluminium [less ▲]
