Through joined two sensitive methods solvation and cloud point extraction separated and determined micro amount of Ce(III) from aqueous solutions by using organic reagent 2,4-Dimethyl pentan-3-one (2,4-DMP) as extractant and non-ionic surfactant 1% TritonX-100 , the experimental study shows the solvation species of Ce+3 extracted into cloud point layer (CPL) have a wavelength for maximum absorb...

AT THIS TIME, the cusp of the twenty-first century, age profiles in many countries are being fundamentally reshaped by population ageing or greying, a process apparently unique in world demographic history and one expected to be sustained well into the future.' Most evident in Europe and elsewhere in the developed world, including Japan, ageing is a global trend, with its symptoms appearing in ...

Images, especially those published in mass and social media, paint a picture that no text or description can capture. Nowhere is this as evident as in recent wars where conflict has frequently had a child's face, often going viral across the world. From the fear and intensity in the eyes of the war orphan Sharbat Gula from Afghanistan, 1 to the sight of poor Alan Kurdi lying dead on a Turkish b...

Editor: In the Talal Amer and Omran M. El-Shmam review published in your journal,1 there are two types of classification for Chiari I malformation: type A, which is associated with syringomyelia and type B, which is not associated with syringomyelia. Hans Chiari (1851–1916) first reported Chiari malformation (1891) morphologically as a cerebellar tonsillar herniation with occasional fourth vent...

Particle swarm optimization (PSO) (Kennedy & Eberhart, 1995) and differential evolution (DE) (Storn & Price, 1995) are two stochastic, population-based optimization methods, which have been applied successfully to a wide range of problems as summarized in Engelbrecht (2005) and Price et al. (2005). A number of variations of both PSO and DE have been developed in the past decade to improve the p...
