Cereal grains are the primary energy source in swine diets. Therefore, not only must producers be concerned about the composition of the grain, but also how it is processed so the pig can fully utilize the nutrients.

There is a strong positive relationship between nuclear genome size and cell size across the eukaryotic domain, but the cause and effect of this relationship is unclear. A positive coupling of cell size and DNA content has also been recorded for various bacteria, suggesting that, with some exceptions, this association might be universal throughout the tree of life. However, the link between cel...

grape is used in large amounts and different types (fresh, raisin, vinegar, molasses, juice, unriped grape and etc). remarkable amount also are preserved in stores and cold-rooms to be supplied out of season, that causes  quality and weight decrease. this research was conducted to study different factors which affect the grape shelf-life. obtaining more information about optimum conditions and ...

fig trees are threatened by the attack of fig mosaic disease (fmd) on leaves and fruits caused by viruses of several genera. shoot-tip culture is a convenient method for viral sanitation. for this purpose, a reliable protocol for rapid in vitro propagation was developed with shoot-tips of three major tunisian local fig (ficus carica l.) varieties zidi (zdi), soltani (sni), bither abiadh (ba) an...
