Growth and form traits data were obtained from eight provenance trials of radiata pine (Pinus radiata D. Don) planted across the radiata pine plantation estate in southeast Australia. The genetic pool included 466 open-pollinated families collected from Año Nuevo, Monterey and Cambria provenances on the Californian mainland coast in the USA and from(More)
This European Respiratory Society task force has reviewed the evidence for paediatric medicines in respiratory disease occurring in adults and children. We describe off-licence use, research priorities and ongoing studies. Off-licence and off-label prescribing in children is widespread and potentially harmful. Research areas in asthma include novel(More)
A simplified method for measuring the effective photon lifetime in an optical resonator was developed. The technique requires the passage of a modulated cw laser beam through the resonator and the measurement of the resultant shift in the phase of the transmitted intensity. The method not only permits a quick and precise measurement of the mirror(More)
The absorption of twenty-four DF laser wavelengths ranging from 3.6128 microm P(1)(6) to 4.0464 microm P(3)(11) was measured for CH(4) , N(2)O, CO(2), and HDO vapor. Total absorption was calculated for the lines for each of these absorbing gases and for the N(2) and H(2)O continua independently and collectively for two representative transmission paths(More)
This article describes the role and function of the Centre for Palliative Care Education and Research at the University of Central England in Birmingham. The authors describe the development of the centre, which is a multidisciplinary venture in collaboration with Cancer Relief Macmillan Fund and palliative care providers throughout the west Midlands.(More)
Open-pollinated progeny tests of American sycamore (Platanus occidentalis L.), which included 55 open-pollinated families selected from several prior Westva–co progeny tests and seed orchards and six control-pollinated families were established in 2002 and 2003. The half-sibling families were planted at two sites in western Kentucky and southeastern(More)
