Pre-Conditioned Cattle Sales for Forage-Based Cow-Calf Management Systems

Demand for preconditioned feeder cattle continues to increase in the beef industry as value-based marketing and information flow expands indicating preconditioned forage-raised calves require less management, fewer losses due to illness and deaths, and increased profitability to both buyer and seller. The goal of a preconditioning program is to increase the value of weaned cattle (Bailey, 2002). The Northeast Texas Beef Improvement Organization (NET-BIO) is comprised of commercial cow/calf and stocker operators and various agribusinesses with the same interest. The objective of this study is to determine if prices received for preconditioned NETBIO stocker cattle increase the net income above preconditioning costs

Overview of the Tevatron Collider Complex: Goals, Operations and Performance

For more than two decades the Tevatron proton-antiproton collider was the centerpiece of the world's high energy physics program. The collider was arguably one of the most complex research instruments ever to reach the operation stage and is widely recognized for numerous physics discoveries and for many technological breakthroughs. In this article we outline the historical background that led to the construction of the Tevatron Collider, the strategy applied to evolution of performance goals over the Tevatron's operational history, and briefly describe operations of each accelerator in the chain and achieved performance.Comment: Includes modifications suggested by reviewer
