The practice of adding low levels of non-commensal yeast and fungi to ruminant diets is increasingly gaining acceptance as a means of manipulating rumen fermentation to benefit production. Reported benefits include an increased degradability of forages in the rumen and an improved flow of microbial protein from the rumen (Williams and Newbold, 1990).Distillery by-products, such as pot ale syrup, are commonly included in ruminant diets as an energy source. However, pot ale syrup contains a substantial number of yeast cells. The aim of the present study was to establish if different yeasts and yeast-containing by-products had similar effects on rumen fermentation to those found with a commercial yeast culture feed additive.Two commercial Saccharomyces cerevisiae preparations (Alkosel, Alko Biotechnology, Finland and Yea-sacc, Alltech, UK), active dried baker's yeast (United Distillers, UK) and two pot ale syrups from the Inchgower and Dailuaine distilleries were compared for their effects on the fermentation in the rumen simulation technique (Rusitec).

The aim of the research presented in this article was studying the basic physico-mechanical parameters of cement-bonded chip boards with hemp used as filler and by-products of energy production applied when modifying the bonding component. Determining and evaluating the basic parameters of boards of modified composition allowed for assessment of the effect of adding or substituting the bonding component within the cement chip board matrix. The work focused on the flexural strength, modulus of elasticity and density. In terms of anomalies in the cement matrix, i.e. uncommon crystalline phases in cement composites, representative samples were selected for differentially thermal and X-ray diffraction analysis.

Nongravitational Effects

AbstractThe nongravitational motion of five “erratic” short-period comets is studied on the basis of published astrometric observations. We present the precession models which successfully link all the observed apparitions of the comets: 21P/Giacobini-Zinner, 31P/Schwassmann-Wachmann 2, 32P/Comas Solá, 37P/Forbes, and 43P/Wolf-Harrington. We used the Sekanina's forced precession model of the rotating cometary nucleus to include the nongravitational terms into equations of the comet's motion. Values of six basic parameters (four connected with the rotating comet nucleus and two describing the precession of spin-axis of the nucleus) have been determined along the orbital elements from positional observations of the comets. The solutions were derived with additional assumptions which introduce instantaneous changes of modulus of reactive force,Aand of maximum of cometary activity with respect to perihelion time. The present precession models impose some contraints on sizes and rotational periods of cometary nuclei. According to our solutions the nucleus of 21P/Giacobini-Zinner with oblateness along the spin-axis of about 0.32 (equatorial to polar radius of 1.46) is the most oblate among five investigated comets.
