Web cache servers (proxies) are increasingly popular for reducing Internet traac and improving response time. The disk subsystem appears to be a bottleneck in such servers. We present techniques for improving disk performance of Web proxies and evaluate them with simulation. The disk workload of proxies has a signiicant volume of new le writes. We show that directing writes to less loaded disks...

Smoking is a major cause of morbidity and mortality in the UK, and the government has funded a range of local and national smoking cessation initiatives. Supporting people as they attempt to give up smoking requires specialist skills and knowledge, often provided by nurses who have received appropriate training. However, non-specialist nurses can also play a role in cutting smoking rates by enc...

As the amount of information resources on the Web keeps increasing so are the concerns for information integrity, confidentiality and authenticity. In Web 2.0 users are producers as well as consumers of content and metadata, which makes guaranteeing the authenticity and integrity of information critical. The scale of the Web requires that any proposals in this direction require minimal (if any)...

in the recent years, nurses haven't contributed much time to research (1). evidence based medicine is becoming more and more popular, and it depends on the nurse's attitudes and knowledge towards research (2-4). without studying the nurse's attitudes towards research, it won't be possible to determine if the findings of the researches are used to improve practice or not (5)....

The principal aim of the differential colorimetry is perhaps to find a system of color representation which is homogeneous and isotropic, i.e., a uniform color space. Such a system would offer certain advantages, especially for the technical procedures, because minimum perceptible differences (differential chromaticity thresholds) would be represented as circles with the same size in the chroma...

LTA Zeolite nanoparticles was successfully synthesized from clear solution under controlled conditions using hydrothermal method using tetramethyl ammonium hydroxide as a structural directing agent. The as-synthesized LTA zeolite particles were characterized by powder X-ray Diffraction (XRD) analysis, Scanning Electron Microscopy (SEM), Fourier Transform InfraRed (FT-IR) spectroscopy, </e...
