1. Preventing pressure ulcers by assessment of the microcirculation in tissue exposed to pressure
Sammanfattning : The overall aim of this thesis was to combine optical methods into a system with the ability to simultaneously measure blood flow changes at different tissue depths. The goal of such a system was to reveal vascular mechanisms relevant to pressure ulcer etiology under clinically relevant conditions and in relation to the evaluation of pressure-redistribution support surfaces.

2. Microbenthos under Pressure : Impacts of human activities on bacteria and meiofauna communities in Baltic soft sediments
Sammanfattning : The marine benthic zone is one of the largest habitats on the planet, harbouring a large diversity of life that underpin many important ecological processes. However, these habitats have been under growing stress from human activities, profoundly altering their living communities. LÄS MER
3. Preferences Under Pressure : Conflict, Threat Cues and Willingness to Compromise
Sammanfattning : Understanding how preferences are formed is a key question in the social sciences. The ability of agents to interact with each other is a prerequisite for well-functioning societies. LÄS MER
4. Fluid dynamic principles for analysis of intracranial pressure control : application towards space medicine and hydrocephalus
Sammanfattning : Intracranial pressure (ICP) is an important component of the fluid dynamic environment of the brain and plays a central role with regards to the maintenance of normal cerebral blood flow and neuronal function. However, many regulatory mechanisms controlling the ICP are still poorly understood. LÄS MER
5. Systemic effects of occupational exposure to arsenic : with special reference to peripheral circulation and nerve function
Sammanfattning : Smelter workers who were exposed to air-borne arsenic for a mean of 23 years, and age-matched referents, were examined with clinical, physiological, and neurophysiological methods. Exposure to arsenic in workroom air was estimated to have been around the Swedish occupational limits, which were 500 yg/m before 1975 and 50 yg/ra thereafter. LÄS MER
