Solvents are used in most chemical, pharmaceutical and laboratory processes. As a result, their physical and chemical properties provide vital information for their optimal selection. This text contains information on over 250 solvents. It answers key questions including What hazards are connected with the use of a specific solvent? How can the molecular order of a solvent be described? Is water a unique solvent? Which solvent should be selected for my application? It also presents previously uncovered material such as listings of molecular sizes, the concepts of order, softness and acid/base data, thermodynamic, electrical, optical and transport properties.
It is Friday the thirteenth, and with the Norwegian capital enveloped in freezing cold, seventy-nine-year-old Reidar Folke Jesperson passes what will be the last day of his life. In the early hours of the following morning he is found stabbed to death in his shop, his naked body exposed in the shop's window, a red string tied round his neck, and three crosses and a number - 195 - written across his chest. Police officers Gunnarstranda and Frolich - the team who were so deeply embroiled in the search for The Fourth Man - are called to the scene. Questions of love and betrayal, loyalty and guilt consume the investigation, just as they fill the private lives of the investigators. What will be uncovered is a country where victims, perpetrators and even police officers are haunted by the past, still trying to cope with the dark memories of the Nazi occupation of the country.
