A multi-port element approach, engineered to address practical design challenges of very high frequency (VHF) phased array radar systems, is presented in this communication. A cornerstone of the antenna element design is its simplicity, which counteracts the mobility issues of physically large and unavoidably bulky ground-based VHF radar systems. The multi-port element introduces a third dimension
STUDY QUESTION: How does a history of cancer affect the likelihood of using assisted reproduction in order to achieve paternity? SUMMARY ANSWER: As compared to men with no history of cancer, use of assisted reproduction to achieve paternity was more frequent in fathers with a history of cancer, mainly those with testicular, prostate, and hematological and lymphatic malignancies. WHAT IS KNOWN ALRE
The Network Function Virtualization paradigm enables the possibility to dynamically instantiate Virtual Network Functions (VNFs) in Commercial-Off-The-Shelf (COTS) hardware. Such VNFs are then concatenated together in Service Chains (SCs) to provide specific Internet services to the users. Depending on latency requirements for such services and considering the aim of maximally consolidating the VN
Popular Abstract in Swedish Målet med avhandlingen är en ökad kostnadseffektivitet i förebyggande behandling av blödarsjuka. Allmän bakgrund om blödarsjuka och förebyggande behandling Blödarsjuka är en ärftlig sjukdom som endast uppträder hos män, även om anlaget överförs av kvinnliga bärare. I Sverige finns ungefär 700 blödarsjuka. Sjukdomen tar sig uttryck i en abnorm blödningsbenägenhet med fThe aim of the thesis was to increase cost-effectiveness in prophylactic treatment of haemophilia. Prophylaxis is effective to prevent bleedings and arthropathy, but the high cost limits its use. First, a new distribution system for clotting factor concentrates was implemented in Sweden to improve availability and reduce risks and costs. Next, optimization of dosing in prophylactic treatment was e
Populärvetenskaplig sammanfattning: Röjningsrösen kan härstamma från bronsålder och ända in i modern tid. De är svåra att datera då det inte finns några karaktäristika för ett röse som skapats under en viss tidsepok. Röjningsröseområden är likväl en stor källa till kunskap om hur jorden brukats under förhistorisk och historisk tid. Med hjälp av paleoekologi kan den förhistoriska miljön studeras. PIn the village Berg, Gällared’s parish, Halland, there is an area with 60 to 75 hectares of abandoned arable fields is present. Within Berg, Yttra Berg’s nature reserve is situated, where 9 hectares of the abandoned arable fields has been recorded, consisting of clearance cairns, terraces and stone walls. Close to the recorded abandoned arable fields a smaller bog, Sänkemosse, is situated. Nearby
Mat som kontaminerats av radionuklider genom till exempel radioaktivt nedfall kan ge höga stråldoser till kroppen. Nuklider med långa halveringstider kan ackumuleras i kroppen och ge en hög tidsintegrerad absorberad dos. Personer med kronisk njursvikt kan erhålla höga stråldoser efter intag av radionuklider eftersom många radionuklider utsöndras via njurarna. I den här undersökningen har vi studerHigh internal radiation doses can result from food, contaminated by radionuclides from for example nuclear fallout. Nuclides with long half-lifes can accumulate in the body and give a high time-integrated absorbed dose. Persons with end-stage renal disease can receive high absorbed doses after intake of radionuclides, since many radionuclides are mainly excreted by the kidneys. In this study the d
This rapport investigates hoarding in Sweden from a fire safety perspective. The aim is to help people, who will meet people suffering from pathological collecting. A study of articles that touched hoarding was made and temperature calculations were done. Swedish building regulations, Jordabalkens chapter regarding rent and the Swedish condominium law where also examined. Hoarding leads in many ca
Uppsatsen är en studie av hur förvaltningsideal påverkar vid rekrytering av chefer till den offentliga förvaltningen och hur förvaltningsidealet är under förändring. Den ger också en kort genomgång av de två vanligaste förvaltningsidealen, Weber och New Public Management, men presenterar även ett tredje alternativ kallat New Public Service. Genom att studera vilka typer av chefer som kommuner öns
Popular Abstract in Swedish Avhandlingen består av ett inledande kapitel och tre essäer, som studerar sjukpenningförsäkringen, sociala normer och sjukskrivning. Den första essän, Group-Specific Social Norms and Economic Incentives in a General Welfare System, behandlar interaktionen mellan ekonomiska och sociala drivkrafter i ett generellt bidragssystem. Vi anknyter resultaten till sjukpenningförThe thesis consists of an introductory chapter and three essays, considering sickness insurance, social norms and absence certification. The first essay, Group-Specific Social Norms and Economic Incentives in a General Welfare System, investigates the interaction between economic incentives and social influences in a general welfare system. We relate the results to sickness insurance. The model i
The Integrated Design Process (IDP) was developed to streamline the design process of (solar integrated) low-energy buildings. One of the biggest differences with the traditional design process is the involvement of engineers and other consultants right from the early design stage. Although the IDP has been fully developed in theory with clear and general descriptions, the practical application of
Service screening with mammography was implemented in Sweden in the late 80's, following the results from trials in Sweden and abroad. A high rate of attendance, a high diagnostic accuracy and treatment in accordance with established guidelines are key circumstances for an effective screening programme. These factors have to be continuously monitored. One trial was carried out 1976-86 in the city
The traditional orthosis are tight and allow minimal evaporation. A new prototype was designed. The thermal foot model tests were carried out at isothermal (Ts=Ta=34 °C) and non-isothermal (Ta=23 °C) conditions with relative humidity set to 17 and 41 %, respectively, and at air velocities of 0.25 (LVa) and 0.85 m/s (HVa). Evaporative resistance (Ret) was calculated based on foot model’s heat loss
The propagation channel determines the fundamental basis of wireless communications, as well as the actual performance of practical systems. Therefore, having good channel models is a prerequisite for developing the next generation wireless systems. This thesis first investigates one of the main channel model building blocks, namely clusters. To understand the concept of clusters and channel chara
Popular Abstract in Swedish Förebyggande miljöskyddslösningar har under flera år tillämpats med stor framgång i den tillverkande industrin. Den har dock används i mycket i liten omfattning i service sektorn. I takt med att tjänstesektorns ekonomiska betydelse ökat, har även miljöaspekten av ett ökat tjänsteutbud kommit i fokus. Denna avhandling förklarar hur förebyggande miljöskydd som ett strategPreventative environmental approaches (e.g. Cleaner Production and Pollution Prevention) have been successfully implemented in the manufacturing industry. They are, however, far from being fully adopted by all society actors. It has, for instance, not been fully embraced by the service sector. When this research project started, the initial question was whether it was possible to adopt experiences
