weather predicts are influence in all aspects of life everyday. more importantly weather warnings are important forecasts because they are used to protect life and property. mesoscale numerical weather prediction models are key for weather forecasting, however the accuracy of the predictions are affected by the errors in the numerical models.study of the clouds is challenging and there are many...

Six cases are presented with macular changes in association with papilloedema; 4 suffered permanent visual loss. The present paper emphasises this previously infrequent finding and discusses the haemodynamic and mechanical factors responsible. The macular changes consisted of haemorrhages situated in front, within, or behind the retina, and occasionally the results of neovascular membrane forma...

Once coalition networks are established, the vulnerability of information systems may increase. Internal propagation of a worm with the characteristics of, for example, “Nimbda” or “Code Red” can generate internal broadcast storms behind the network firewalls. There are significant limitations to applying simulation information security issues. Most security vulnerabilities occur at the end poi...

THE importance of adequate fluid and electrolyte therapy is now readily appreciated, and the principles underlying the correction of deficiencies are well established. Everywhere the importance of base conservation by the body is accepted, and measures taken to correct any deficiency of base substance are rigorously applied. We appreciate clearly the difference between a true water deficiency a...

Heparin is widely used in current practice for a variety of indications. It is well known that it can cause thrombocytopenia, but not that thrombosis may also develop in thrombocytopenic patients and cause significant morbidity and mortality. A 56-year-old woman developed heparin-induced thrombocytopenia with thrombosis that resulted in the amputation of her leg. It is proposed that the reactio...
