An alternative to uncontrolled, excessive, build-up of pressure, followed by uncontrolled explosion, is the provision of a buffer vessel, in which there is separation of hydrogen from radioactive products in permeable membrane separators. The hydrogen is then flared. Possible rates of production of hydrogen are compared, along with the rates at which it can be separated and flared in lifted jet flames, which give the highest burn rates. Cross winds can result in a transition to rim attached, downwash and wake-attached flames, all with a signicantly reduced burn rate, or complete flame extinction. The performance of lifted jet flames of C3H8, CH4 and C2H4, when exposed to increasing air cross winds velocities, are presented. These provide a basis for synthesisi...

Through the examination of the interlacing of the personal, the political and the national in their testimonities, we argue that these women contribute to the discussion of the relationship between memory and history; to the relation between interiors and exteriors; and to the understanding of the constitution of and ideal self that narrates women in transit to its emancipation. Here the diverse frames and angles of vision trace, retrospectively, a horizon of a gendered type of citizenship in Nicargua, women's ideas and political commitment in the middle of the 20th century.

Data on these accidents, which occurred after 1961, were taken from several sources. Aspects analyzed included the accident scenario, the type of accident, the materials involved, the causes and consequences and the most common accident sequences. The analysis showed that the most frequent causes are external events (31%) and mechanical failure (29%). Storage areas (35%) and process plants (28%) are by far the most common settings for domino accidents. Eighty-nine per cent of the accidents involved flammable materials, the most frequent of which was LPG. The domino effect sequences were analyzed using relative probability event trees. The most frequent sequences were explosion → fire (27.6%), fire → explosion (27.5%) and fire → fire (17.8%).
