the aim of this study is to map the chronological achievements of public health over the past 100 years in a small island state and to outline emerging themes. a retrospective analysis of data was conducted from the published population and vital statistics reports of the central statistical office for the period of 1953-2006, as well as all available published reports of the ministry of health...

the independent model used by meyer and schramm (here after m&s) for determining the age ofelements (chemical evolution) is extended. using new and extended definitions and including parametersignored by m&s, the galactic evolution equations are solved to determine the total duration ofnucleosynthesis,t. to be able to calculate the t t (mean age time for formation of elements to total ...

In this work, the hydrogeochemistry and environmental isotopic compositions of thermal and mineral springs in Arxan, northeastern China, were used to assess the genesis of the thermal system hosted by deep-seated faults. The reservoir temperature was calculated using the mineral saturation index and geothermometers. According to isotopic analysis, the spring water was of meteoric origin. Sixtee...

Many studies were conducted to investigate arsenic mobilization in different alluvial plains worldwide. However, due to the unique endemic disease associated with arsenic (As) contamination in Taiwan, a recent research was re-initiated to understand the transport behavior of arsenic in a localized alluvial plain. A comprehensive approach towards arsenic mobility, binding, and chemical speciatio...
