Robert Le Rossignol , 1884 – 1976 : Engineer of the ‘ Haber ’ Process
In March 1908, the BASF at Ludwigshafen provided financial support to Fritz Haber in his attempt to synthesize ammonia from the elements. The process that now famously bears his name was demonstrated to BASF in July 1909. However, its engineer was Haber’s private assistant, Robert Le Rossignol, a young British chemist from the Channel Islands with whom Haber made a generous financial arrangemen...

متن کاملSome Properties of rw-Sets and rw-Continuous Functions
In 1937, Stone [6] introduced and investigated the regular open sets. These sets are contained in the family of open sets since a set is regular open if it is equal to the interior of its closure. In 1978, Cameron [2] also introduced and investigated the concept of a regular semiopen set. A set A is regular semiopen if there is a regular open set U such that U ⊆ A ⊆ U . In 2007, a new class of ...
متن کاملPohl-Warnsdorf – Revisited
Two new series of graphs are introduced. Properties of these graphs make them suitable as test beds for Hamiltonian path heuristics. The graphs are planar and regular of degree 3, and each series has a simple recursive definition. These graphs are “conceptual adversaries” to methods that try to exploit local characteristics. For each series, we give an analysis showing that the number of Hamilt...
