Alfalfa protein is poorly utilised by ruminants due to its rapid degradation in rumen. The objective of the study was to assess the influence of spraying tannic acid (TA) on chopped alfalfa hay on in vitro rumen fermentation and nitrogen (N) retentio

New pump module concepts had to be developed for space borne applications, because a simple transformation of terrestrial solutions to space requirements was often not useful. A planar approach has been chosen, which prevents inherent draw-backs of s

Diode lasers with 400- μm stripe widths measured in pulsed-current mode are shown to reach peak (saturation) powers of 60 W for 1-ms pulses (60 mJ) and 189 W for 300-ns pulses ( ~ 55 μJ). Use of laterally structured contact and etched index guides

First results on epitaxial-side (epi-down) mounting of terahertz quantum-cascade lasers (QCLs) on sapphire submounts using indium solder are presented. The single-plasmon ridge waveguide lasers emit in the range 3.1–3.3 THz. An epi-down mounting sc

A new mini-bar design densely packed with 13 emitters in a 1.6 mm aperture has been developed. These mini-bars deliver >200 W output. With a very low divergence of 95% power enclosed in 25° they are suitable for fast axis collimation (FAC) lenses wi

The loss of protein by plant proteases during ensiling of forage legumes reduces forage quality, causing both lower animal performance and potential by negatively impacting on nitrogen loss to the environment. Polyphenol oxidase (PPO) enzyme catalyze

SUMMARYBrody (1945) concluded that the inflection point of the growth curve of domestic animals coincides with the onset of puberty and is coupled with an increase in proportion of fat gain at that time. This purported coincidence of growth inflectio
