Since the inception of the National Mycobacterial Surveillance System (NMSS) in 1991, annual crude notification rates for tuberculosis have remained stable at between 5 and 6 per 100,000 population. In 1998, there was a total of 923 TB notifications in Australia of which 884 were new TB cases, and 39 relapsed cases. The corresponding annual crude notification rate for new and relapsed TB was 4....

Despite changes in technology that have improved both production and the final product, small local journals still have a low profile and struggle to obtain adequate copy, in terms of both quality and quantity. My experiences as editor of two small journals in Jamaica in the 1990s provided similar problems to those that are encountered by many editors today. Endeavour to persevere, but, if you ...

A photosensor is an electronic control device that adjusts the light output of a lighting system based on detected illuminance. While some photosensors simply switch lights on and off, Specifier Reports: Photosensors focuses on photosensors that are used with dimming electronic ballasts to adjust the light output of fluorescent lighting systems over a continuous range. These photosensors are mo...

specific basic-helix-loop-helix protein expressed in mesenchymal and glomerular epithelial cells in the developing kidney, 37 a novel mouse gene of the immunoglobulin super-family, is expressed predominantly in the developing nervous sys

There is a broad spectrum of data that can be used to describe the health of young people in the UK. These data are of varying quality, reflecting in part the methods used to collect them. However, it is often frustrating trying to locate information relevant to young people: so many of the apparently obvious sources of data, such as routine surveillance data, are either not collated centrally,...

The aim of this set of lectures is a systematic presentation of a 1 + 3 covariant approach to studying the geometry, dynamics, and observational properties of relativistic cosmological models. In giving (i) the basic 1 + 3 covariant relations for a cosmological fluid, the present lectures cover some of the same ground as a previous set of Cargèse lectures [7], but they then go on to give (ii) t...

This document summarizes a range of possible techniques for the repair of continuous media streams subject to packet loss. The techniques discussed include redundant transmission, retransmission, interleaving and forward error correction. The range of applicability of these techniques is noted, together with the protocol requirements and dependencies.

In a case of first impression in the state of New York, the highest state court decided that a prior written agreement between progenitors of frozen embryos regarding the disposition of their ?pre-zygotes? in the event of divorce is binding. By copying the general result arrived at by the Tennessee Supreme Court in Davis v. Davis in 1992, the New York court magnified the weight of authority in ...

T he Cardiovascular and Renal Advisory Panel of the FDA met January 27-28, 1998, to discuss (1) evaluation and use of intravenous inotropic agents in patients with heart failure; (2) liver function test abnormalities with a new AT 1 receptor blocker, tasosartan; and (3) the use of the platelet IIb/IIIa receptor blocker eptifibatide in syndromes of acute cardiac ischemia. Intravenous drugs for t...
