Abstract: Disclosed are xylose-fermenting recombinant yeast strains expressing xylose reductase, xylitol dehydrogenase, and xylulokinase and having reduced expression of PHO13 or a PHO13 ortholog, as well as methods of fermenting xylose to obtain ethanol using the recombinant yeast strains.

Abstract: A kneepad is formed of a shell and a detachable cushioning pad. The shell includes a knee area and a shin area. A non-flowable gel is provided in the cushioning pad. Preferably the gel is indented at the normal pressure point of contact of the patella. The outer surface of the shell is provided with a plurality of ribs surrounding a recessed portion to direct the pressure and shocks from the ground to the outer portions of the knee. The shell may also be provided with a resilient material between the ribs and the inner surface of the shell.

Preferably the gel is indented at the normal pressure point of contact of the patella. The outer surface of the shell is provided with a plurality of ribs surrounding a central inwardly recessed portion to direct the pressure and shocks from the ground to the outer portions of the knee. The shell may also be provided with a resilient material between the ribs and the inner surface of the shell.
