The objective was to investigate if diffusing laser fibres can be modelled as conductive heat sources without miscalculating coagulated volumes, and if finite element analysis, disregarding light transport, may be used for three dimensional (3D) treatment planning in interstitial laser thermotherapy (ILT). Temperature distributions and coagulated volumes with a diffusing laser fibre, as compared t
Purpose: In this study, numerical simulations are performed to compare the adiabatic film cooling effectiveness and reveal the difference of film cooling mechanisms of two models with the same geometries and cross-section areas of film holes’ exits at three typical blowing ratios (M = 0.5, 1 and 1.5). The two models are an elliptical model and a cylindrical model with 90° compound angle, respectiv
Intraosseous (IO) access is normally reserved for emergencies and critical care conditions when venous cannulation is not possible. Nonetheless, we present a case of IO insertion to a 56-year-old man, tetraplegic for many years due to progressive spinal muscular atrophy and with refractory suffering. The IO access was used for palliative sedation with propofol in a home care setting. The patient d
Purpose: Elevated cardiac troponin levels have been shown to be associated with a poor prognosis under some intensive care conditions. This study investigated whether inclusion of high-sensitivity troponin T (hsTnT) increased the prognostic accuracy of the Simplified Acute Physiology Score (SAPS 3) for general intensive care unit (ICU) patients, cardiac arrest patients, or patients with a non-card
Systemic hyperglycemia and hypercapnia severely aggravate ischemic brain damage when instituted prior to cerebral ischemia. An aberrant cell signaling following ischemia has been proposed to be involved in ischemic cell death, affecting protein kinase C (PKC) and the calcium calmodulin kinase II (CaMKII). Using a cardiac arrest model of global brain ischemia of 10 min duration, we investigated the
ABSTRACT— A model is described in which transient ischemia is induced in rats anaesthetized with N2O:O2 (70:30) by bilateral carotid artery clamping combined with a lowering of mean arterial blood pressure to 50 mm Hg, the latter being achieved by bleeding, or by bleeding supplemented with administration of trimetaphan or phentolamine. By the use of intubation, muscle paralysis with suxamethonium
The present study aimed to study the relation between the release of arachidonic acid (AA) and the energy state in cerebral cortices of rats during single episodes of cortical spreading depression (CSD). The changes in concentrations of AA, labile phosphate compounds [ATP, ADP, AMP, and phosphocreatine (PCr)], and glycolytic metabolites (lactate, pyruvate, glucose, and glycogen) were studied durin
Human activities and climate change affect hydrological and sedimentological characteristics within catchments. For arid and semiarid areas this induces direct negative economic and environmental consequences on society. In fact, stability in the rainfall regime and less siltation trapped in reservoirs mean more water for irrigation, water supply, and better flood control. This is especially impor
Under 2012–2014 organiserade VIWAFU, ett nätverk för internationellt och interdisciplinärt forskarsamarbete i Norden och Baltikum, fyra seminarier för master-studenter, doktorander och post-docs. Var och ett av seminarierna hade ett tema, t.ex. VA-branschens reglering och styrning, infrastruktur för dricksvatten, innovativ utveckling inom kommunala vattenfrågor samt vattenhantering i turistområdenViable Water Management and Governance for Futures (VIWAFU), a professional network for international and interdisciplinary collaboration amongst researchers from the Nordic and Baltic countries, was built for providing and sharing knowledge on water management and governance for future policy and decision making during the years 2012–2014. VIWAFU organized four workshops for MSc students, PhD stu
In the global market of air transport, integration of products and services is now seen as being necessary for the long-term success of engine manufacturers. This paper describes research stimulated by a fundamental shift that is occurring in the manufacture and marketing of aero engines for commercial and defence purposes, away from the selling of products to the provision of services. Our collab
The conventional view is that Sweden transformed its economy and institutions more slowly than other countries after the structural crisis of the late 1970s, and this is held as an explanation for Sweden’s poor economic growth thereafter. This paper questions that view in several aspects. First, it points out that Sweden has performed comparatively well since the end of the EMS crisis. Second, Swe
One factor which can be expected to influence performance in applications where the user is expected to point a device in some direction to obtain information is the angle interval in which the user gets feedback. The present study was performed in order to get a better understanding of the influence of this angle interval on navigation performance. Results indicate that users are able to handle q
