“…Studies have shown that mix‐linked β‐glucan and arabinoxylan are easily hydrolysed by β‐glucanase and xylanase respectively (Marković et al., 1998; Courtin and Delcour, 2001). Addition of cell wall degrading enzymes in vitro increased the release of proteins and non‐starch carbohydrate in barley (Boisen and Fernández, 1997).…”

The effects of supplementing a barley-based diet for weaned piglets withexogenous beta-glucanase and xylanase on gastrointestinal digestiveenzyme activities were investigated. Thirty-six cross-bred weaned pigletswere randomly assigned to two groups with three pens based on sexand mass. Each group was fed on the diet based on barley with or withoutadded beta-glucanase and xylanase (0.15%) for a 4-week period. Theresults showed that enzyme supplementation improved growth performanceof piglets significantly (p < 0.05), but had no effect (p = 0.091)on average daily feed intake. The results also showed that supplementationof beta-glucanase and xylanase had no effect on pepsin activity in gastriccontents but slightly decreased (p = 0.092) the pepsin activity ingastric mucosa. Meanwhile, no effect of enzyme supplementation ontrypsin activity in duodenal contents was observed. However, the activitiesof amylase and lipase in duodenal contents were significantly(p < 0.05) decreased, whereas the activities of maltase, sucrase andgamma-glutamyl transpeptidase (gamma-GT) in jejunal and ileal mucosa wereenhanced significantly (p < 0.05). The improvement of disaccharidaseand gamma-GT activity may be attributed to the positive impacts of exogenousenzymes on digestion and absorption of the nutrients. In conclusion,the current results indicated that supplementation with enzymes in barley-based diets could improve the growth performance of piglets,decrease the activities of amylase and lipase in duodenal contents andincrease the activities of disaccharidase and gamma-GT in jejunal and ilealmucosa.

“…The use of ceremix and cereflo have been found to be more effective in the preparation of beer wort as observed for the result obtained in equal proportion of sorghum and malt barley. The low performance of some of the enzymes may be as a result of the environmental changes such as temperature, ion strength and they could alter the proportion of enzymes, and consequently, produce certain changes in substrate hydrolysis pattern [16]. Therefore, stabilisation is important during the process.…”

The effect of commercial enzymes on quality of wort developed from replacement of malted barley (100%) with sorghum as adjunct 50%, 60%, 70%, and 80% was investigated for pH, colour, filteration rate, extract asin, dry extract, viscosity, total soluble nitrogen and free amino nitrogen. The wort pH (5.6 -6.0) is relatively stable with no significant changes at all levels of replacements. The colour is lighter with increment in proportion of the sorghum as it appears as colour diluents. Wort filteration rate is reduced with the sorghum replacement and the wort produced tends to be turbid which affects the utilization of the wort. The total soluble nitrogen and free amino nitrogen value increased with the use of commercial enzymes while the viscosity decreases with enzymes. The use of ceremix and cereflo have been found to be relatively more effective in the preparation of beer wort as observed for the result obtained in proportions of sorghum and malt barley. The use of high percentage sorghum as adjunct with commercial enzymes are found to be useful in production of high quality wort with low cost and profitability.

“…Y de hecho se puede ver, en ocasiones, que cinco o más en orden sucesivo son empujados por las leves brisas, cuando uno pende de otro adhiriéndose por debajo, y cada uno a su vez del otro conoce la fuerza vinculante de la piedra Esta forma de ejemplificar le permite al poeta dar cuenta de la coherencia de su sistema teórico y, al igual que Epicuro, procura asirse, a través de argumentaciones retóricas, de datos tomados de la realidad sensible para homologarlos con la realidad "in-visible", "no perceptible" o res caeca. 23 En consecuencia, exige la atención de su interlocutor para continuar con la exposición de su material, ya que la linealidad discursiva, -"the linear medium of communication", como afirma Markovic 24 -posibilitará aprehender la complejidad del universo:…”

La piedra imán: de Lucrecio a Claudiano; de la ciencia a la mitología

En De rerum natura VI, en el contexto de las “maravillas” naturales, Lucrecio analiza la fisiología del magnetismo (VI.906-920) y sus efectos (VI.998-1099). Claudio Claudiano, cinco siglos después, resignifica las argumentaciones del poeta romano sobre la piedra imán, en un poema de los Carmina minora. A diferencia de Lucrecio, Claudiano resigna las conclusiones científicas para abocarse a la descripción de la inexplicable atracción que ejerce la piedra sobre el hierro. A partir de lo señalado, la comunicación pretende analizar los esfuerzos lucrecianos por explicar el magnetismo y las transformaciones operadas por Claudiano, quien fusiona hábilmente la ciencia y la poesía.
