Research ArticleOpen accessIn the abstractLIPASE-CATALYZED TRANSESTERIFICATION OF PALM KERNEL OIL WITH DIALKYLCARBONATESTjahjono Herawan, M. Rüsch Gen. KlaasLipase-catalyzed transesterifications-especially in a solvent-free medium-are important for industrial applications because such systems would have an enormous advantage by avoiding the problem of separation, toxicity and flammability of organic solvents. However, the organic solvent-free alcoholysis, especially methanolysis, does not give high conversions. The same problem also occurs when ethyl or methyl acetate are used as acyl acceptors. The main problems … …American Journal of Applied Sciences, Vol. 11, Issue 8 · 6 May 2014 · 6,798 accessesView PDFCite
Research ArticleOpen accessIn the abstractNEWER DRUGS FOR VISCERAL LEISHMANIASIS: A REVIEWKrishna Pandey, Dharmendra Singh, Sanjiva Bimal et al.Visceral Leishmaniasis (VL) is one of the most neglected tropical diseases worldwide.

Research ArticleOpen accessIn the abstractDiscovery of Dynamical 3-Space: Theory, Experiments and Observations-A ReviewReginald T. CahillThe existence of space as a dynamical system was recently revealed in 2002, following the discovery that the Michelson-Morley light speed anisotropy experiment of 1887 was not null. Numerous later experiments have confirmed that discovery, as reviewed here, with the latest being the discovery of a very simple and cheap nanotechnology quantum detector method for observing space and its fluctuations/turbulence: … …Space Science International, Vol. 1, Issue 2 · 2 Jan 2014 · 13,030 accessesView PDFCite
