Four Holstein steers (466 kg) with cannulas in the rumen and proximal duodenum were used in a 4 X 4 Latin square design experiment to evaluate the ruminal escape protein value and post ruminal digestibility of menhaden fish meal (FM) vs two high-bypass protein blends in an 88% concentrate finishing diet. Blend 1 (B-1) contained 5% fish meal, 25% meat and bone meal, 20% blood meal, and 50% hydro...

Many mathematical models arising in science and engineering, including circuit and device simulation in VLSI, constrained mechanical systems in robotics and vehicle simulation, certain models in early vision and incompressible uid ow, lead to computationally challenging problems of di erential equations with constraints, and more particularly to high-index, semi-explicit di erential-algebraic e...
