    Keywords : Endomorphin; flexor reflex; galanin; knock-out mice; neuropathic pain; nociceptin; orphanin FQ transgenic mice;

    Abstract : Nociception and/or the sensation of pain is essential for the survival of the organism.

Without such mechanisms, it would be impossible to turn ones focus away from even the most minor painful stimulus. READ MORE

  5. 3. More Water, Less Grass? : An assessment of resource degradation and stakeholders’ perceptions of environmental change in Ombuga Grassland, Northern Namibia

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Environmental monitoring; semi-arid; pastoralism; rural water supply; indicators; local knowledge; vegetation survey; satellite remote sensing; Physical geography; Naturgeografi; geografi med naturgeografisk inriktning; Physical Geography;

    Abstract : The objectives of this thesis are to assess: to what degree have natural resources deteriorated in a grazing area in northern Namibia, how do perceptions of environmental change held by local stakeholders there, correspond to scientific assessments, and how do these relate to national estimates? Analysis of the process of developing national indicators for monitoring of land degradation concluded that specific indicators should be developed on national level, and in some instances even on local level as there are no universal causes of land degradation. According to farmers overgrazing and low rainfall since the early 1990s cause negative environmental changes in the study area, partly confirming findings from national monitoring. READ MORE
