Chris Marshall Chris Marshall, who died on August 8 at age 66, was a world-renowned cell biologist best known for his pioneering contributions to oncogene research and to cell signaling via GTPases, especially to our understanding of tumor cell signaling through the Ras-Raf-Mek-Erk pathway. He spent the whole of his independent research career at the Chester Beatty Laboratories of the Institute...

The Fall cone liquid limit testing procedure for low plasticity soil mixtures with sand, including the sample preparation and implementation of plastic determination suggestions are covered within this research. A apparatus was used in order to determine limits types, which Casagrande cup thread rolling methods proved inapplicable. Several issues addressed concerning standardized mixture fillin...

This paper uses 3D numerical analyses to investigate the stress path experienced by soil elements around large diameter piles in sand subjected monotonic drained lateral loading. Inspection of loading-induced stresses revealed multiaxial nature these paths, which are characterised rotation one or more principal axes. Based on outcome finite element analyses, typical paths for different extracte...

Helicobacter pylori is an important human pathogen and a gram-negative, spiral shaped and microaerophilic bacteria with persistence colonization in gastric mucosa, causes gastroduodenal inflammation and destruction, resulting in diseases such as duodenal ulcer disease, gastric ulcer disease. When H.pylori discovered by Warren and Marshall, effective therapy developed for this infection and resu...
