This contribution presents the results of a research projects analysing some aspects of stability failure of thin-walled RHS compression members that are likely to exhibit combined global and local buckling. In particular the influence of various imperfections, namely residual stresses due to welding and local as well as global geometrical defects, on the load-carrying capacity is subjected to detailed experimental and numerical investigations. The insight into the structural behaviour leads to recommendations for standardized imperfections that should be used in the context of the numerical modelling of class-4 square and rectangular hollow section members subjected to compression.

Spring, W. Zeitschrift fuer Chemie und Industrie der Kolloide (1909), 4, 161-8; SciFinder (Chemical Abstracts Service: Columbus, OH); https://scifinder.cas.org (accessed July 8, 2010). Objections to Chevreuil's, Hillger's, Falk's, and Knapp's theories for the cleansing action of soap are presented. Experiments on the action of soap sols. on carefully purified lampblack bring out the following facts: Lampblack (charged +) hastens the formation of an acid salt (charged -) then forms an adsorption compound with it. A suspension of lampblack in soap sol. will run through filter paper while lampblack can be filtered from water sol. because of an adsorption compound between it and the filter paper. A 1% soap sol. gives an optimum suspension of lampblack, while a 2% is about equivalent to water. Small amounts of alkali increase the suspending power of a sol. greatly. 0.2-0.16% sols. of soap in MeOH, and 0.05% sol. in EtOH show the same optimum suspension for lampblack. The residue of soap obtained by evaporating a given vol. of sol. is the same, whether C has settled through it or not, but the ash in that residue is greater when C has been present, i. e., the basic part is higher in ash than the acid part. From MeOH the ash is less and the C has combined with the basic soap. From EtOH there is practically no difference. The C settled from soap sol. is a thick sirup, and cannot be purified, but forms a colloidal sol. in H2O. C in H2O is uncharged, but in alkaline sol. is + charged. From a 2% soap sol. a white ppt. of C + acid soap collects about the anode, and is lower in ash than soap obtained from the sol. by evaporation.
