. and finally dried in air at 60°C. The XRD pattern of prepared powder sample was col- lected using a Rigaku D/ Max-2200PC X-ray diffractometer using CuKα radiation (λ = 1 5 417 8 Å) and a graphite. was transferred into a commercial stainless steel Tef- lon-lined autoclave of 50 mL capacity. The autoclave was maintained at a temperature of 18 0°C for 12 h without stirring and shaking during....

. From the 19 95 data for England and Wales, an estimated start -of- year population for 19 95 was derived. Age-specific baseline hazard rates from 19 96 onwards were assumed equal to those for 19 95, and. Table 4. As noted above, the total number of deaths must always equal the size of the population at the start of 2000; but the temporal pattern of the deaths depends will differ if the hazar...
