knowledge. It was not unpleasant simply to sit and read, and should be useful to people interested in learning more about the medical beliefs and practices of this period. Mental illness, mental retardation, and substance abuse are important concerns today, but they are not recent phenomena. A consideration of mental disability in a historical context is essential to an understanding of the cur...

A novel fiber-optic electrochemiluninescence sensor has been developed. It can be conveniently applied by placing into the sample solution in a manner similar to a conventional ion selective electrode, without requiring liquid luminous reagent and a flowing system. The sensor is consisted of an independent probe and a case for exclusion the ambient light, allowing the sample solution to pass th...

In the present study a cloud-point extraction process using non-ionic surfactant Triton X-114 for selective extraction of gallium from aqueous solutions was developed. The method is based on the complex formation of Ga (III) with N, N′ -bis (salycilidene)-1, 2-phenylenediamine (salophen) as a chelating agent in buffer media of pH 5. After phase separation and dilution of the surfactant-rich pha...

By accurately optimizing the growth conditions for an oxygen doped AlN nucleation layer and for the subsequent epitaxial process the crystal quality of our GaN could drastically be improved. In X-ray diffraction (XRD) analyses we observed FWHM values of 39 arcsec and 114 arcsec for the symmetric (004) and asymmetric (114) reflection, respectively. Consequently, the nominally undoped samples sho...
