Neck support pillows are widely used in patients with neck pain to reduce pain and get better quality of sleep. To test whether specific neck pillows have any effect on neck pain, headache and quality of sleep in people with chronic non-specific neck pain and to find the optimal characteristics of such a pillow, 52 patients with chronic neck pain tested four different pillows (three specially desi

The presented work is motivated by Free Space Optics (FSO) communications. FSO is a well established wireless optical transmission technology considered as an alternative to radio communications for example in metropolitan wireless mesh networks. An FSO link is established by means of a laser beam between the transmitter and the receiver placed in the line of sight. A major disadvantage of FSO lin

SLF’s vårexkursion gick till trakterna av Kumla och Örebro med Mikael Hagström som arrangör. En god skara människor hade slutit upp och trotsade de initialt urusla vädret, men som tur var bättrade det sig. Med på exkursionen var Martin Westberg, Samantha Fernandez Brime, Ulf Arup, Emil Persson, Sten Svantesson, Stefan Ekman, Linnea Eide-Ekman, Måns Svensson, Lovisa Fogelberg, Ola Hammarström, JespSLF’s vårexkursion gick till trakterna av Kumla och Örebro med Mikael Hagström som arrangör.

Many engineers and scientists prevalently use computational tools in electromagnetics, which is also the predominant case for antennas. The ever-increasing number of applications and technologies that employ antennas create a constant demand to improve and extend existing tools and develop new ones. This dissertation investigates computational tools for antenna analysis and design. Antenna current

Background: This prospective study focuses on factors associated with arterial damage in children with type 1 diabetes (T1D). Materials and Methods: Eighty children and adolescents with T1D (mean age 15, range: 8-20 yrs; mean diabetes duration 7, range: 0.5 to 19 years) were investigated twice, approximately 2 years apart, for carotid artery intima-media thickness (cIMT) and compliance (CAC), flow

Den yttersta barriären mellan luften och blodomloppet i våra lungor består av en lipid-protein film. Denna lipid-protein blandning kallas för lungsurfaktant. Filmen bestående av lungsurfaktant stabiliserar alveolerna i våra lungor och gör att vi kan andas utan motstånd. Brist av lungsurfaktant kan orsaka svåra sjukdomar, till exempel hos förtidigt födda barn som ännu inte hunnit bilda tillräckligtThis thesis explores lipid self-assembly and aims to give a broad picture of self-assembly structures in simple and complex lipid-protein systems. The systems studied are lung surfactant, stratum corneum and simple model membranes. The lung surfactant mixture lines the alveolus in our lungs and stabilises the air- tissue interface. The lung surfactant lipid phase behaviour was here investigated wi

Background Breathlessness is associated with major adverse health outcomes and is twice as common in women as men in the general population. We evaluated whether this is related to their lower absolute lung volumes. Methods Cross-sectional analysis of the population-based Swedish CardioPulmonarybioImage Study (SCAPIS) Pilot, including static spirometry and diffusing capacity (n = 1,013; 49% women)

Aims/hypothesis: Maggots of the blowfly Lucilia sericata are used for the treatment of chronic wounds. As monocytes may contribute to the excessive inflammatory responses in such wounds, this study focussed on the effects of maggot secretions on the pro-inflammatory activities of these cells. Methods: Freshly isolated monocytes were incubated with a range of secretions for 1 h and then stimulated

Gebel el-Silsila displays an astounding concentration of incised illustrations, of which anthropomorphic figures are frequent motifs. These figures were produced over several millennia; from prehistoric petroglyphs to pictorial graffiti of dynastic periods and throughout into Roman days. Spanning over six millennia visitors to Gebel el Silsila depicted huntsmen, warriors, boatmen, and horsemen, reGebel el Silsila displays an astounding concentration of incised illustrations, of which anthropomorphic figures are frequent motifs.

Purpose: Transportation systems play a key role in providing individuals with a diversity of means to access their desired destinations and have significant impacts on their quality of life. The social perspective of mobility is, however, marginalized in the current model of transportation planning and significant changes are called for. This study aims to identify the barriers and opportunities o

Introduction Chronic breathlessness is highly prevalent and distressing to patients and families. No medication is registered for its symptomatic reduction. The strongest evidence is for regular, low-dose, extended-release (ER) oral morphine. A recent large phase III study suggests the subgroup most likely to benefit have chronic obstructive pulmonary disease (COPD) and modified Medical Research C

Glucagon-like peptide-1 (GLP-1) is a gut peptide that regulates food intake and glucose metabolism. GLP-1 is also produced and released in the brain, and GLP-1 receptors are expressed in brain regions important for alcohol and drug reward, and for the development of addiction. GLP-1 receptor agonists can decrease alcohol intake acutely in rodents. However, alcohol use disorder is a chronic conditi
