Unlike ordinary refined products, high waxy crude oil has a potential serious safety problem during transportation because of its non-Newtonian characteristic. Further, the operating parameters of the pipeline and physical properties of the crudes are varied. Hence a common practice for the waxy crude pipeline operator is to overheat the transported crude in order to avoid any potential safety problems...
Acetoin (3-hydroxy-2-butanone) is an important flavor compound, widely existing in dairy products and some fruits. An study has been performed on acetoin production Bacillus subtilis TH-49. The mutant was obtained by treating B. subtilis NT-50-44 with compound mutation and subjecting it to a shake flask fermentation selection procedure. It was proved that the main metabolite produced by mutant strain...
We report on a new iterative method for regularizing a nonlinear operator equation in Hilbert spaces. The proposed IIGRA algorithm is combination of nonlinear implicit iterative method and a gradient method for minimizing a modified Tikhonov functional. Under some not very strict assumptions, we will give a convergence result. Finally we present two numerical results for integral equation and parameter...
