Budgeting soil erosion from floodplain sediments of the central Rhenish Slate Mountains (Westerwald), Germany
2011
The distribution, thickness and composition of the floodplain sediments in the valleys of the Gelbach (Lower Westerwald) and Große Nister (Upper Westerwald) depend on the occurrence of loessic periglacial cover beds in their catchments as well as on historical land use. The budget of floodplain sedimentation was derived from a study of the floodloams underlying the monastery garden of Marienstatt, a village in the Große Nister valley. From the study of two occupation levels, pottery shards and radiocarbon dating, 55% of the floodloam can be attributed to the Modern period (younger than c. AD 1450). From the radiocarbon age of a charcoal fragment extracted from the base of the floodloam at …

'Anestheticography': on-line monitoring and documentation of inhalational anesthesia.
1988
The safe practice of inhalational anesthesia requires control over the amount of volatile anesthetic delivered to the patient. With minimal fresh gas flow this is facilitated by continuous monitoring and recording of the agent's concentration ('Anestheticography'). Alterations brought about by routine clinical maneuvers become visible. We recorded the course of the inspiratory and expiratory concentration of volatile anesthetic (Isoflurane) by infrared absorption and a trend recorder. Changing the carrier gas composition during high flow from 75% to 25% nitrous oxide in oxygen resulted in a 10% increase of the inspiratory isoflurane concentration. Activating the oxygen bypass or exchanging …
Investigation of nitrogen and helium cryosorption on molecular sieves
1994
Abstract The helium-containing plasma exhaust gases of Tokamaks can be pumped by cryopumps using cryosorption panels coated with solid porous materials. The best pumping characteristics are achieved with activated charcoal and molecular sieves at temperatures below 10 K. In order to select the most suitable material with respect to cryosorption properties and reactivation behaviour, comparative tests on various molecular sieve types differing in cavity structure, pore size and polarity were carried out. Nitrogen and helium adsorption isotherms were determined at LN 2 temperature and at 14.5 K, respectively, expecting that an extrapolation mechanism between the adsorption properties of both …
