Incidence of childhood cancers
Incidence of childhood cancers About 1,800 cases of childhood (under the age of 15 years) cancer are newly diagnosed every year in Germany. With an overall population of approx. 11 million children under the age of 15 years, this means an annual incidence of about 16.6 per 100,000 children in this age group. The likelihood that a newborn child will develop a malignant disease within the first 1...
متن کاملIncidence and Trend of Childhood and Adolescent Cancers in Yazd, Iran
Abstract Background Data on childhood and adolescent malignant tumors incidence are skimp in developing countries. In this study, we analyzed the incidence and trend of childhood and adolescent cancers in Yazd city, center of Iran between Jan 2004 and Dec 2013. Materials and Methods The various types of malignant tumors were grouped pursuant to the Interna...
متن کاملEmpirical models to predict parsimoniously the mass and number concentrations of ultrafine particulate in ambient atmosphere.
The main objective of this study was to develop parsimonious empirical models for predicting the mass and number concentrations of ultrafine particulate (UFP, aerodynamic diameter < 0.1 or 0.18 microm) in the atmospheric environment. We found strong correlations existed between the mass/number concentration of UFP and the mass concentration of PM(2.5) (aerodynamic diameter < 2.5 microm) by fitt...
متن کاملUltrafine Particle References
A review of the physical characteristics of sulfur-containing aerosols, with respect to size distribution of the physical distribution, sulfur distributions, distribution modal characteristics, nuclei formation rates, aerosol growth characteristics, and in situ measurement, has been made. Physical size distributions can be characterized well by a trimodal model consisting of three additive log-...
متن کاملThe mapping of fine and ultrafine particle concentrations in an engine machining and assembly facility.
Aerosol mapping was used to assess particle number and mass concentration in an engine machining and assembly facility in the winter and spring. Number and mass concentration maps were constructed from data collected with two mobile sampling carts, each equipped with a condensation particle counter (10 nm < diameter < 1 microm) and an optical particle counter (300 nm < diameter < 20 microm). Nu...
