Computerized data has become critical to the survival of an enterprise. Companies must have a strategy for recovering their data should a disaster such as a fire destroy the primary data center. Current mechanisms offer data managers a stark choice: rely on affordable tape but risk the loss of a full day of data and face many hours or even days to recover,(More)
There is a great deal of research about improving Web server performance and building better, faster servers, but little research in characterizing servers and the load imposed upon them. While some tremendously popular and busy sites, such as netscape.com, playboy.com, and altavista.com, receive several million hits per day, most servers are never(More)
As le systems grow in size, ensuring that data is safely stored becomes more and more di cult. Historically, le system backup strategies have focused on logical backup where les are written in their entirety to the backup media. An alternative is physical backup where the disk blocks that make up the le system are written to the backup media. This paper(More)
Parameters of iron uptake have been determined for blade tissue of Macrocystis pyrifera (L.) C. Ag. These include the effects of iron concentration, light, various inhibitors, and blade type. All experiments were conducted in the defined artificial seawater Aquil. Iron uptake is light independent, energy dependent, and dependent on the reduction from Fe(3+)(More)
The biosynthesis of 4-hydroxybenzaldehyde and 3-bromo-4-hydroxybenzaldehyde from l-[U-(14)C]tyrosine has been demonstrated in chloroplast-containing fractions obtained by differential and isopycnic centrifugation from the marine red alga Odonthalia floccosa. Surfactant and high speed centrifugation studies indicate that the biosynthetic pathway involves a(More)
World Wide Web clients and servers have become some of the most important applications in our computing base, and we need realistic and meaningful ways of measuring their performance. Current server benchmarks do not capture the wide variation that we see in servers and are not accurate in their characterization of web traffic. In this paper, we present a(More)

The World Wide Web has captured the public’s interest like no other computer application or tool. In response, businesses have attempted to capitalize on the Web’s popularity. As a result propaganda, assumption, and unfounded theories have taken the place of facts, scientific analysis, and well-reasoned theories. As with all things, the Web’s popularity(More)
Radiation Oncology Practice Standards have been developed over the last 10 years and were published for use in Australia in 2011. Although the majority of the radiation oncology community supports the implementation of the standards, there has been no mechanism for uniform assessment or governance. North Coast Cancer Institute's public radiation oncology(More)
