As the number of people under the age of 65 declines, the number over 65 will double in the next half century. By 2031, it is estimated those over 65 will account for more than a quarter of the Australian population. The fastest rate of growth will be in the over-as-years category, projected to double over the next 20 years and to triple over 50 years to include 2.3 million people. Health care ...
background: serologic screening of gastric cancer (gc) by serum pepsinogens (spg) levels and helicobacter pylori (hp) sero-status, though highly informative, has provided heterogeneous results. here, we have evaluated the modifying effects of demographic factors on the risk impact of hp sero-status/spg levels in gastric cancer, with particular emphasis on age. methods: a cross-sectional study w...
BACKGROUND An ageing population has service planners concerned about future levels of disease which are age dependent. Predictions of mortality for colorectal, lung and breast cancers, which account for 30% of cancer cases and 40% of cancers deaths, were calculated for 2010 and 2015, based on trends in death rates and the predicted change in the demography of the Northern Ireland population. ...
Demography is the science of human populations and, at its most basic, focuses on the processes of (i) fertility, (ii) mortality and (iii) mobility. Whereas modern states are typically in a reasonable position to keep records on both fertility and mortality, through birth and death registrations, as well as through censuses, measuring the mobility of populations represents a particular challeng...
In the present work, the influence of aging temperature on mechanical properties and sound velocity of Maraging steel M350 was investigated. For this purpose, first, samples were solution annealed at 825◦C for 2 hours and then age hardened at 510◦C-600◦C for 3 hours. Hardness, tensile and impact tests were used for determining mechanical properties and longitudinal ultrasonic velocity was used ...
Many social scientists have taken note of the re-emerging interest in issues concerning social processes embedded within a spatial context. While some argue that this awakening is refreshing and new and, in fact, long overdue, I demonstrate that spatially focused demographic theories and research agendas clearly predate contemporary interest in these topics. I assert that recent methodological ...
