We introduce a new NCP-function in order to reformulate the nonlinear complementarity problem as a nonsmooth system of equations. This new NCP-function turns out to have stronger theoretical properties than the widely used Fischer-Burmeister function and other NCP-functions suggested previously. Moreover, numerical experience indicates that a semismooth Newton method based on this new NCP-funct...

Salam (2010) Molecular QED of coherent and incoherent sum-frequency and second-harmonic generation in chiral liquids in the presence of a static electric field, Molecular Physics, 108:14, 185...
The influence of copper promoters and reaction conditions on the formation of alcohols byproducts of a common Fischer-Tropsch synthesis used iron-based catalysts were investigated. A good compromise of 28%Cu/FeKLaSiO2 can lead to the optimization of an improved Fischer-Tropsch catalyst. The product distribution shifts towards hydrocarbons with increasing the reaction temperature, while pressure...
The first examples of reactions of Fischer carbene complexes with triynes are reported. The regioselectivity of the reaction of the two different alkyne functions in the symmetrical triyne depends on the nature of the substituent of the triyne. Bis-silyl-substituted triynes react at the central alkyne unit, whereas bis-aryl- and bis-alkyl-substituted triynes react at the end alkyne unit. The re...
The relationship between dietary fat and mammary carcinogenesis was examined by feeding a high-fat or a low-fat purified diet, differing only in fat and carbohydrate content, to Fischer, Long-Evans, and Sprague-Dawley rats. An additional group of rats from each strain was fed a nonpurified laboratory diet for comparison. The rats were given an i.v. dose of A/-nitrosomethylurea (50 mg/kg body we...
This perspective offers an overview of using nanomaterials for understanding cobalt catalysed Fischer-Tropsch chemistry. Nanomaterials now afford unprecedented control of size, shape and structure at the nanometre scale. This makes them invaluable tools for studying heterogeneous catalysis. The Fischer-Tropsch reaction, especially using cobalt based catalysts, is a linchpin in many processes fo...

Inbred Fischer rats fed on an iodine-deficient diet for 16-22 months will develop goiters which will grow into tumors when transplanted subc-utaneously into the flanks of other Fischer rats. We have studied the biologic behavior, histology, and the chromosomes of 1-7 generations of ten lines ot these transplanted thyroid tumors and classified them into three categories: (a) Dependent tumors wit...
One of the first eager readers of Steinitz’s paper was Emmy Noether. At the time when the paper appeared she was still living in her hometown Erlangen, during what may be called the period of her apprenticeship, studying the highlights of contemporary mathematics of the time. Her guide and mentor in this period was Ernst Fischer. We can almost be sure that Steinitz’s paper was the object of ext...
