Objectives: We evaluated a method for gas monitoring in the mastoid cavity using tunable diode laser spectroscopy by comparing it to simultaneously obtained computed tomographic (CT) scans. Methods: The presented optical technique measures free gases, oxygen (O2), and water vapor (H2O) within human tissue by use of low-power diode lasers. Laser light was sent into the tip of the mastoid process
BACKGROUND AND OBJECTIVES: Transfusion of blood products in particular older products is associated with patient morbidity. Previously, we demonstrated a higher incidence of acute lung injury in lipopolysaccharide-treated sheep transfused with stored blood products. As transfusion following haemorrhage is more common, we aimed to determine whether a 'first hit' of isolated haemorrhage would prec
During the Younger Dryas cold event, the Scandinavian ice sheet readvanced in southwest Sweden and formed the Middle Swedish end-moraine zone (MSEMZ). Recent highway construction near Skara has created an exposure through the prominent ridge at Ledsjo. Through sketching and measurement of structural information, we have documented the internal character of the Ledsjo moraine. The moraine consists

Översiktliga beräkningar visar att ca 2 miljoner människor utsätts för trafikbullernivåer överstigande de riktvärden som riksdagen ställt sig bakom. Ungefär 500 000 av dessa utsätts för buller från tågtrafiken. Trafikbuller har betydelse för vår hälsa och de negativa effekterna kan vara störning av dagliga aktiviteter, stress sömnsvårigheter, koncentrationsproblem och högt blodtryck. Detta arbete Roughly 2 million Swedish citizens are exposed to traffic noise from roads, railways and aircrafts at levels higher than those approved by the government. As many as 500 000 of these are subject to railway noise. Exposure to traffic noise can have negative effects and cause irritation and disturbance of daily activities and also create general health problems such as lack of sleep, stress, concent
Uppsatsen granskar och analyserar ACTA, ett färskt internationellt avtal om verkställighet av immateriella rättigheter. Analysen sker ur både mikro- och makroperspektiv. På mikronivån avser analysen det materiella innehållet och incitamenten till förstärkningar på regelnivå. Avtalets räckvidd (scope) liksom titelns relevans diskuteras separat. På makroplanet analyseras de politiska incitamenten i The thesis scrutinizes and analyses ACTA, a recently finished international agreement on enforcement of intellectual property rights. The analysis is performed on both a micro and a macro level. On the micro level, the analysis concerns the substantive content and the incentives to enhance the protection on the level of individual provisions. The scope and the title of the agreement is dealt with
A supply chain is often complex in nature. Goods, information, and money shall flow in and between companies in a simple and cost effective manner. There are a number of tools that companies can use to control and manage the supply chain in an efficient manner. In this work, two types of IT-based tools are compared i.e integrated and best-of-breed solutions. The questions this work will try to ans
When conducting laser based diagnostics in combustion environments it is often desirable to obtain temporally resolved information. This can be due to several factors such as combustion taking place in a turbulent flow field, flame propagation from a spark plug in an initially quiescent combustible mixture, or rapid, multi-point fuel consumption in a homogeneous charge as a result of compression i
The purpose of the thesis is to study whether any special professional norms exist with regard to principals’ leadership of the democratic mission which is presented to the schools. The aim is to identify norms in order to be able to later analyse and understand them. Norms exist in groups of various types, and by using the term “norm” I am addressing the actions of principals, rather than their i
Purpose – Cassava production surged noticeably in Southeastern Africa beginning in the 1990s. The purpose of this paper is to examine the commercial responses and food security consequences of cassava production growth in the region. Design/methodology/approach – The paper incorporates a mix of quantitative analysis, based primarily on original analysis of national farm household survey data, toge
Since the mid 1900s, the “ the Swedish model ”, has contributed to that all Swedish citiziens has a right to community benefits in case of illnesses, accidents or unemployment. For this system to work, there has to be a mutual trust between the taxpayers and the government; everyone has to take responsibility and notify the government if they´re no longer in need of the benefit. The main focus in
The aim of this study was to find an understanding of elderly care staff´s views on documentation requirement and documentation as a task and also to examine managers views on implementation of new tasks. We wanted to enter more deeply into the tension between the managers´ expectations, based on the set of goals made from politicians, and the response of this from the elderly care staff and what
Under de senaste 15 åren har användningen av frekvenselektromagnetiska sonderingsinstrument inom geofysiska undersökningar drivit forskningen framåt för att förbättra den använda metoden. En av dessa tekniker är inversion vilket är den process som omvandlar elektromagnetiska data till djupvärden för geologiska lager. Inversion av frekvenselektromagnetiska data har länge varit förknippat med svårigThe adoption of frequency electromagnetic (EM) sounding devices in the past 15 years for geophysical exploration has fueled research into techniques associated with the method. One of these techniques is inversion which is the process of turning the EM data into measurements of depth for different geological layers. Inversion of frequency EM data has classically been difficult and unreliable. With
Samernas traditionella landområde Sápmi breder ut sig över norra Norge, Sverige, Finland och Kolahalvön i Ryssland, och omfattar därmed stora delar av Sveriges mest mineralrika områden. Storskaliga utvinningsprojekt har varit föremål för flera intensiva konflikter mellan samerna och staten, och gett upphov till såväl lokala protestaktioner som nationell debatt. I egenskap av urfolk åtnjuter samernSápmi, the traditional lands of the indigenous Sami people, expands across northern Norway, Sweden, Finland and into the Russian Kola Peninsula. It contains several of Sweden’s major mineral deposits. Large-scale extraction projects have been the subject of intense conflicts between the Sami and the Swedish state and has given rise to local protests as well as nation-wide political debate. Indigen
I långa vita korridorer med oräkneliga antal lysrör finns en värld som byggs upp av mjuka ting som läkare och sjuksköterskor, men även mer och mer hårda ting - teknik. Vad händer när bryggan mellan de mjuka och hårda tingen inte byggs med dem båda i åtanke? WHO beskriver att nästan ett av tio fel som sker med medicinsk teknik beror på användaren. Dessa fel skulle kunna undvikas om system designadeAs incidences of chronic diseases increase, the tools to diagnose, treat and monitor such conditions become more important. Medical imaging technologies, being one of these tools, still face challenges in safe and effective use. At the same time, poor design of medical devices causes errors that could be avoided using proper design methods. The master thesis is written in collaboration with Bild
Popular Abstract in Swedish Radiojodbehandling av sköldkörteln är den vanligaste radiofarmakaterapin. För att beräkna aktiviteten 131I som krävs för att ge en viss stråldos till sköldkörteln behöver sköldkörtelns massa och den individuella biokinetiken bestämmas. Biokinetiken består vanligtvis av det individuella upptaget av jodid och den biologiska halveringstiden av jod i sköldkörteln. Den bioloRadioiodine therapy of hyperthyroidism is the most frequently performed radiopharmaceutical therapy. To calculate the activity of 131-I to be administered for giving a certain absorbed dose to the thyroid, the mass of the thyroid and the individual biokinetic data, normally in the form of uptake and biologic half-time, have to be determined. The biologic half-time is estimated from several uptake
The transformation from analogue to digital recording techniques has not only changed the ways of working for the studiotechnician, but affects the musician in the way he thinks about performance and sound, and therefore also his actual performance. The signal processing and the staging of the singing voice in the studio is both influenced by, and influences the estethics of popular song performa
Transition-metal complexes have long attracted interest for fundamental chemical reactivity studies and possible use in solar energy conversion(1,2). Electronic excitation, ligand loss from the metal centre, or a combination of both, creates changes in charge and spin density at the metal site(3-11) that need to be controlled to optimize complexes for photocatalytic hydrogen production(8) and sele
