  2. 1. Minimal volume ventilation in lung injury : With special reference to apnea and buffer treatment

    Author : Staffan Höstman; Anders Larsson; Hans Hjelmqvist; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; VILI; THAM; buffers; apneic oxygenation; respiratory acidosis; hypercapnia; low volume ventilation; mechanical ventilation; ultra-protective ventilation; Anestesiologi och intensivvård; Anaesthesiology and Intensive Care;

    Abstract : A fairly large portion of patients receiving surgical or intensive care will need mechanical ventilation at some point. The potential ventilator-induced lung injury (VILI) is thus of interest. One of the main causal factors in VILI is the cyclic energy shifts, i.e. READ MORE

  4. 2. Grow with the flow : Hydrological controls of riparian vegetation in boreal stream networks

    Author : Lenka Kuglerová; Roland Jansson; Hjalmar Laudon; Birgitta Malm-Renöfält; John Stella; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; boreal forest; channelization; groundwater; Krycklan catchment; liverworts; mosses; riparian buffers; riparian vegetation; river restoration; species richness; stream network; stream size; vascular plants;

    Abstract : What drives species diversity across landscapes is one of the most fundamental questions in ecology. Further, understanding the mechanisms underlying species diversity patterns is important not only for forming and challenging ecological theories but also essential for appropriate landscape management and effective nature conservation.

  6. 4. Forested buffers in agricultural landscapes : mitigation effects on stream–riparian meta-ecosystems

    Author : Jasmina Sargac; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Stream–riparian meta-ecosystems are strongly connected through exchanges ofenergy, material and organisms. Land use can disrupt ecological connectivity byaffecting community composition directly and/or indirectly by altering the instreamand riparian habitats that support biological structure and function.

  7. 5. Measurement and control of oxygen fugacity by means of gaseous oxygen buffers

    Author : Sven Berglund; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Fundamental and practical aspects of oxygen buffering are reviewed, with particular reference to the gaseous oxygen buffer as a tool in elevated temperature oxide chemistry. An oxygen buffer capacity concept and a classification scheme for oxygen buffers are proposed; their application is demonstrated. READ MORE
