Measuring carbon monoxide content in muscles

A method ist described to determine the CO-content in the tissue of muscles. The prepared tissue is pulverized in a swinging mill at the temperature of liquid nitrogen. Parts of the powder are weighed into headspace vessels. Carbon monoxide ist ejected by a formerly described method and measured gaschromatographically. The Fe-content is determined after an acid disintegration by AAS. Acute intoxications lead to higher CO-contents in heart than in periphere muscles. Chronic exposure to carbon monoxide does not produce these differences.     

Sudden death in angiodysplasia of the gastroesophageal junction.

A 22-year-old Korean soldier, who had received blows to the neck and epigastrium from an officer 10 h earlier, suddenly died after massive hematemesis. He had been in relatively good health except for episodes of blood-tinged vomiting approximately 5 and 7 months prior to this event. Postmortem examination revealed angiodysplasia involving the gastroesophageal junction, and the stomach was distended with blood. No abnormal findings were present around the whole viscera, and the duodenum was free of blood. The pathologic significance of upper gastrointestinal angiodysplasia as a potential source of bleeding and a chronologic correlation between the trauma and bleeding are discussed.     

The use of either the nose or outer ear as a means of determining the postmortem period of a human corpse.

Presented in this paper are the initial results involving the use of the nose or outer ear as temperature measurement sites to determine the postmortem period of the human corpse. Simple mathematical models for both sites are developed based on cooling curves of five corpses. Analysis of errors between actual and calculated postmortem intervals suggest that in its present form, the described methods would not be suitable for use in accurately determining the time since death of human corpses.     

From Journeymen Envoys to Skilled Diplomats: Change in Canada's Education-Related International Activities, 1815-1968

For much of the nineteenth century, Canadian education-related international activities resided outside the realm of traditional diplomacy. This situation was exacerbated by Canada's colonial link with Great Britain. Obstacles that prevented educationalists from playing a more substantive role in diplomacy were local, imperial, and ecclesiastical in origin. Educational activities were also a tool in the service of governments in the era between the zenith of British Imperialism in the 1890s and the founding of the United Nations in 1945. In the post-1945 era there was greater collaboration between the federal Ministry of External Affairs and provincial ministries of education. Education also emerged in the late twentieth century as part of the new diplomacy. A flowering of new international governmental organizations dedicated to furthering creative diplomacy brought new energy to this field.
