This experiment evaluated the effect of 2 levels of diet concentrate (20 and 40% of DM) and 2 levels of ruminally undegraded protein (RUP: 25 and 40% of CP) on nutrient intake, total and partial apparent nutrient digestibility, microbial protein synthesis, and ruminal and physiological variables. Eight Nellore heifers (233 +/- 14 kg of BW) fitted with ruminal, abomasal, and ileal cannulas were ...

Models from methods like Contextual Design (CD) are a sound basis for requirements engineering. But current software engineering processes are not prepared to use such models. Together with tight schedule and budget project teams settle for the minimal work needed, which is writing use cases in case of the Rational Unified Process (RUP). HCI practitioners more and more need HCI methods effectiv...

Author uses software engineering tools and RUP methodology to manage design of control for complex systems. UML diagrams are used to describe requirements and to model the system on high level of abstraction. Graphical approach with RUP and UML helps to integrate subsystems of different nature and to eliminate main risks of failure of the control subsystem project. Examples of different UML dia...

In this paper1, I describe new process elements that allow RUP to overcome these weaknesses. I discuss some experiences in which RUP has been used to assist IT organizations in achieving a higher level of process capabilities, then present the software process improvement approach that we are using to guide our work. I also describe the new process elements that would be created to overcome the...

BACKGROUND Studies of perennial peanut (Arachis glabrata Benth.) suggest its hay and haylage have greater levels of rumen undegraded protein (RUP) than other legume forages such as alfalfa (Medicago sativa L.). Greater RUP can result in more efficient nitrogen utilization by ruminant animals with positive economic and environmental effects. We sought to determine whether, like red clover (Trifo...

Accordingly, the standards are not tied back to the The application-to-application exchange of business data, known as electronic data interchange (EDI), has not fulfilled the expected potential. The focus for the development of EDI standards should be shifted from the interchange file to the information contained within the business process. The use of object oriented techniques to model the s...

Ten ruminally cannulated lactating Holstein cows that were part of a larger trial studying the effects of feeding different proteins on milk production were used in a replicated 5 x 5 Latin square to quantify flows of microbial and rumen-undegradable protein (RUP) in omasal digesta. Cows were fed total mixed rations containing (dry matter basis) 44% corn silage, 22% alfalfa silage, 2% urea, and...

The objectives of this experiment were to measure intestinal digestibility of AA in the rumen-undegraded protein fraction (RUP-AA) of distillers dried grains with solubles (DDGS) and fish meal (FM) samples and to determine whether these feeds contain a constant protein fraction that is undegradable in the rumen and indigestible in the small intestine, as assumed in the French Institut National ...

Recent tests of a 250 m/m structured packing in a 1.22 m diameter column have produced some unanticipated results. Using two quite different systems, mass transfer performance in a relatively short 1.69 m bed was significantly better than previous results in a longer 3.78 m bed. No bed length effect was found on pressure drop. Two different severe vapor maldistributions were studied using a vac...

In the last twenty years, elaborate models have been developed to formulate diets with greater accuracy in meeting the protein and amino acid requirements of lactating dairy cattle. Models for feeding protein to dairy cattle in the USA evolved from basic crude protein (NRC, 1978) to more complex systems based on rumen undegraded protein (RUP) and intestinal digestion of RUP (NRC, 2001). The NRC...
