Hart, K.P. and J. van Mill, Discrete sets and the maximal totally bounded group topology, Journal of Pure and Applied Algebra 70 (1991) 73-80. If G is an Abelian group, then G # is G with its maximal totally bounded group topology. We prove that every A c G# contains a closed (in G#) and discrete subset B such that lB1 = IAl. This answers a question posed by Eric van Douwen. We also present an ...

parkinson`s disease (pd) is the second most common neurodegenerative disorder after alzheimer`s disease. it is a chronic and progressive disease, and mostly afflicts elderlies. pd starts with sudden onsets and the exact cause of the disease is still unknown, however there are some early symptoms that can help us to diagnose the disease and ameliorate its effects. pd is a multi-factorial disease...

The functionality of tissue engineering scaffolds can be enhanced by localized delivery of appropriate biological macromolecules incorporated within biodegradable nanoparticles. In this research, chitosan/58 S-bioactive glass (58 S-BG) containing poly(lactic-co-glycolic) acid (PLGA) nanoparticles has been prepared and then characterized. The effects of further addition of 58 S-BG on the structu...
