The design and features of frequency-selective wallpaper created for attachment onto regular walls in order to filter out signals operating at 5 GHz while at the same time allowing the desired radio communication services to propagate through such walls are presented. An analysis of the characteristics of the radio channel evaluated in a typical indoor environment, when considering either regular

The blade tip region encounters high thermal loads because of the hot gas leakage flows, and it must therefore be cooled to ensure a long durability and safe operation. A common way to cool a blade tip is to design serpentine passages with 180-deg turn under the blade tip-cap inside the turbine blade. Improved internal convective cooling is therefore required to increase the blade tip lifetime. Di

OBJECTIVE: Although fear of birth is common during pregnancy and childbirth, the best treatment for fear of birth in clinical care remain unclear. Strong evidence suggests that continuity models of midwifery care can benefit women and birth outcomes, though such models are rare in Sweden. Because women with fear of birth could benefit from such models, the aim of this qualitative study was to exam

In order to significantly improve engine efficiency and reduce exhaust emissions at the same time, new radical combustion concepts have emerged. Gasoline partially premixed combustion (PPC) is one of them, with early results showing high gross indicated efficiency. To achieve that, PPC relies on high EGR (exhaust gas recirculation) use, with numbers that can reach up to 50%. Such a high amount of

The structure and function of proteins are strongly affected by the surrounding solvent water, for example through hydrogen bonds and the hydrophobic effect. These interactions depend not only on the position, but also on the orientation, of the water molecules around the protein. Therefore, it is often vital to know the detailed orientations of the surrounding ordered water molecules. Such inform

The water sector in Somalia is fragmented and needs coordination to establish a functioning water governance system. Therefore, commitments from all affected stakeholders are needed to support water resources development in Somalia. This paper proposed a water compact for Somalia that can address all water sector challenges to approach sustainability. The paper starts by analyzing water sector sta

Background: Telephone nursing in primary healthcare has been suggested as a solution to the increased demand for easy access to healthcare, increased number of patients with complex problems, and lack of general practitioners. Registered nurses' assessments may also be of great importance for antibiotic prescriptions according to guidelines. The aim of this study was to describe registered nurses'

'Sustainability' is an emerging issue that product development engineers must engage with to remain relevant, competitive and, most importantly, responsible. Yet, on examining the term 'sustainable', a plethora of definitions emerges, many of which are contradictory and confusing. This confusion and a general lack of understanding means that sustainability often gets relegated to an afterthought o

“- However, if you believe that relieving pain with pills is the cure, you are putting your head in a bush. A bush of thorns” – A critical discourse analysis of mental illness in the Swedish daily press The aim of this study was, from a discourse analytical approach, to investigate similarities and differences in how it was talked about mental illness in the past and how it¬ is talked about menta

In recent years, mobile phones and GPS have become increasingly common tools for people working in elderly care. In the home care service, the mobile phone is now completely central to planning who will do what and when. The aim of the study was to investigate how home care staff shape their view of care work in the light of the mobile phones they use. The method chosen for this study was qualitiv

I detta examensarbete har en vägdagvattendamm i Lunds nordöstra stadsdel Brunnshög undersökts och modellerats. Syftet med studien var dels att ta fram en metod för att mäta sedimenteringshastigheter hos partiklar i dammen, dels att bygga upp en 3D-modell av dammen och simulera flödet samt fördelningen av suspenderade ämnen för på så sätt försöka avgöra var i dammen det lämpar sig bäst att ta ut va

Omkring 10% av Sveriges befolkning lider av kronisk njursjukdom. För de flesta patienter med långt gången, så kallad terminal njursjukdom är njurtransplantation den bästa behandlingen, både för patientens livskvalitet och ur ett hälsoekonomiskt perspektiv. Många patienter som har en villig donator passar inte med denna på grund av icke kompatibla blodgrupper eller för att de har antikroppar motBackground: For most patients with end stage renal disease (ESRD) kidney transplantation is the best treatment option. Best outcomes are achieved with living donation. To increase access to living donation for patients who are not compatible with their living donors, Kidney Exchange Programs (KEPs) have evolved. By exchanging donors, compatibility can be achieved thus enabling transplantation.

Byggindustrin står inför nya utmaningar i form av skärpta krav när det gäller dess klimatpåverkan. En betydande faktor för byggindustrins klimatpåverkan är den cement som används i betong, eftersom det i samband med tillverkning av cement frigörs stora mängder koldioxid. Platta på mark är en vanlig typ av grundläggning i byggnader i mindre skala, såsom småhus. En typisk småhusplatta av betong ha

En stor del inom utvecklingen av nya produkter är test och validering. Denna process kräver användning av dyra och stora testsystem. På grund av dessa faktorer är det viktigt att maximera användningen av dessa testsystem. Till följd av detta har ett övervakningssystem utvecklats av test- och validerings-avdelningen på BorgWarner i Landskrona som kan läsa driftstatus (Till exempel på och av) av visA large part of developing products is the testing and validation of the new products. This process requires expensive test systems and a great deal of time and space. Because of these factors it is very important to maximize the usage of the test systems. Therefore, a monitoring system has been developed by the test and validation department at BorgWarner Landskrona that can read the operational

The Silurian strata of Gotland yield a wide variety of polychaete jaws. The investigated polychaetes include the family Polychaetaspidae with the two genera Polychaetaspis and Kozlowskiprion, and the monotypic family Ramphoprionidae with the genus Ramphoprion. The fauna derives from the sections at Lusklint and Lickershamn 2 which comprise the three stratigraphically oldest units on Gotland: the L

Heavy trucks vehicles by design often suffer from issues causing driver discomfort. That discomfort is here considered caused by oscillations in the driveline, which are affecting the driver. The driveline oscillations – sometimes referred to as shunt and shuffle - exist because of the sheer amount of power in a heavy truck engine, combined with a driveline where the components are relatively weak

Cottrell och Neuberg utförde en studie 2005, Different Emotional Reactions to Different Groups: A Sociofunctional Threat-Based Approach to “Prejudice”, i USA med syfte att undersöka om det fanns kopplingar mellan känslor och upplevda hot. De undersökte detta ur ett sociofunktionellt perspektiv och förutspådde att olika hotfulla grupper skulle framkalla diverse emotionella reaktioner hos ingruppen.

Populärvetenskaplig sammanfattning: Supernovor och andra galaktiska system skickar ut mängder av atomkärnor med nära ljusets hastighet, så kallad kosmisk strålning. Eftersom supernovor framförallt finns i spiralarmarna i vår galax och jorden över långa tidsperioder rör sig relativt spiralarmarna så har det föreslagits att kosmisk strålning inte varit konstant under jordens historia. Vidare har visIt has been suggested that the cosmic ray flux varies as Earth moves relative to the spiral arms in the galaxy. However, no satisfying record over the cosmic ray flux over long time scales has been presented. This work aims to investigate the possibility to use cosmic ray tracks in silicate mineral inclusions in sediment-dispersed extraterrestrial chromite (SEC) grains as such a record. Chromite i

Solar power clearly has one of the greatest potential among renewable energy but a big setback is that it is still relatively expensive. Engineering of materials on a nanoscale, e.g. the growth of nanowires makes it possible to make semiconductor-materials with better optical properties while using less material than for traditional bulk semiconductors. This means that nanowire based solar cells h
