This report describes the construction work of a radar antenna for the radar systemCARABAS. CARABAS is a long wave airborne ground radar that has been developed bySAAB Microwave Systems and will now be mounted on a small helicopter, Schweizer 300.The antenna should be able to fold up and down. When the radar is in use the antenna islowered and under transport, start and landing the antenna is folded up. An emergency dropfunction should also be included in the design of CARABAS III.The extent of this report includes construction of the antenna, frame structure attached to thehelicopter, mechanism for folding the antenna up and down and mechanism for emergencydrop function. The mechanical design of the antenna and frame structure is based on modaland stress analysis, vibration measurement of Schweizer 300 and frequency analysis, andcalculations regarding aerodynamic drag and mechanics.The exciting frequencies of the helicopter and accelerations at those frequencies weredetermined by vibration measurement and frequency analysis.

This study is about children that have been forced to flee to another country, due to conflict, poverty or natural disasters, without their families. They are known as unaccompanied refugee children. The aim of the study is to, by focusing on individual children's feelings and experiences of being forced to flee create greater knowledge and understanding of what is hidden behind some of the statistic of migration.To answer the aim of the study, I used the following research questions: How is a child affected by being forced to leave home and to flee to a foreign country? How does an unaccompanied refugee child perceive the exodus? How do the unaccompanied refugee children handle their situation during the flight and at arrival in Sweden?The study is based on a qualitative method and consists in semi-structured interviews with five unaccompanied refugee children aged 17 to 21. The theoretical framework is based on three theoretical concepts; refugee crisis, identity and coping.The study results show that these children are a very vulnerable group, who were forced to be exposed to several losses and traumas.

Bakgrund: Inom intensivvård transporteras patienter till och från avdeningen för att genomgå olika undersökningar. Det är väl känt att transporter är förenade med risker och kritiska situationer uppstår ofta på grund av den mänskliga faktorn. Genom upprepad utbildning av personal, tillexempel genom simuleringsövningar med informanter ur olika yrkeskategorier kan det vara ett användbart verktyg för att uppnå ökad vårdkvalitet och patientsäkerhet.Syfte: Studiens syfte var att beskriva vad en simuleringsövning innebär för intensivvårdspersonal för att bemästra en kritisk situation.Metod: En kvalitativ studie med induktiv ansats har genomförts. Femton personer, varav sex ST-läkare, sex sjuksköterskor och tre undersköterskor inom intensivvård har intervjuats. Konventionell kvalitativ innehållsanalys enligt Hsieh och Shannon har använts för analys av materialet.Resultat: Analysen av materialet ledde till att nio stycken subkategorier utvecklades och som delades in i två kategorier, vilka beskriver informanternas upplevelser i situationen och betydelsen av lärandet.

The Swedish market for vehicle inspection is re-regulated since June 2010. More than four years after the re-regulation there are eight companies in the market. Two of these companies are a result of the former monopolist's owners divided the business among themselves. The remaining six companies have entered the market through acquisitions or by building up their business from scratch, these are known as new entrants in the study. The competition has developed slowly and the former monopolist still has the highest market share.

This report describes the master thesis project ?Weight Optimization of a Composite Chassis for a Multimodal Lightweight Vehicle? which is a part of the Master program in Naval Architecture and a part of a research project at the Centre for Naval Architecture, KTH. Demands on smart and energy efficient transport solutions are continuously increasing. In the Stockholm region the citizens are expected to increase with 25% and the road vehicles with 80% until 2030, putting high demands on the traffic system. Using a small multimodal vehicle deals with this problem and uses both the land and waterways for transportation.

This study is a part of a larger project where the aim has been to evaluate different methods to assure the quality in stallion semen, due to the fact that some stallions in horse breeding have poor semen quality. The increased use of transport semen requires new methods to ensure good semen quality. In this part of the project the viability and concentration in fresh and cooled semen was examined with NucleoCounter SP-100. A comparison between two different commercially available semen extenders, Kenney?s and INRA 96, was made.

The euthropthication of the Baltic Sea is a threat that is beginning to be taken seriously by the governments concerned. In Sweden, regulations concerning the allowed nitrogen (N) concentration in the effluent water from wastewater treatment plants are being tightened up. The Rimbo wastewater treatment plant has been imposed to reduce the annual mean concentration of total N in the effluent water to levels below 15 mg l-1. A more and more common way to reduce the nitrogen level in wastewater is to let the water pass through a wetland. This study investigates the possibility to build this kind of wetland at the outlet of the Rimbo wastewater treatment plant.A prestudy of the topography, soil characteristics and groundwater flow indicates that the land area in question is well suited for the construction of a wetland.

Riksdagens skatteutskott beslutade den 28 februari 2012 att det behövde göras en utredning avseende regelverket för F-skatt. Av utredningen framkom att regelverket har möjliggjort för arbetsgivare att säga upp sin personal och sedan låta dem jobba kvar som egenföretagare i form av F-skattare. Det framkom även att det specifikt inom åkeribranschen förekommer att uppdragsgivaren säger upp sina anställda chaufförer och istället anlitar utländska påstådda egenföretagare som chaufförer. Följden av detta är att den svenska uppdragsgivaren slipper betala arbetsgivaravgifter och undkommer mervärdesskatt. Det innebär i sin tur att Sverige förlorar en hel del skatteintäkter.Uppsatsen behandlar denna problematik avseende åkeribranschen genom att den utreder två situationer med utländska egenföretagare som chaufförer.

Peat  lands  are  a  great  potential  resource  for  increased  forest  growth  in  Sweden, there  are  approximately  6.5  million  hectares  of  peat  lands,  whereof  around  70% produce less wood than one m3sk/ha and year and are therefore classed as forest waste  land.  There  are  over  200  000  hectares  of  peat  land  that  is  already  drained and  wooded,  and  that may  be  suitable  for  fertilization.  Forest  production  on  peat soils  usually  requires  drainage  and  fertilization.  Dewatering  requires  ditching  the area, so that the roots can have access to oxygen. Nitrogen is often abundant in the peat but other nutrients; especially potassium is in short supply. The  purpose  of  this  work  was  to examine  the effects  of  potassium  fertilization  on the  growth  of  spruces  that  were  planted  on  drained  peat  land  and  how  different amount of fertilizers affects the growth. Potassium deficiency is strongly growth inhibiting, since potassium is important for substance  transport  in  the  tree.  Potassium  is  also  important  for  the  carbohydrate formation, and because increasing the sugar content of the cells constitutes a lower freezing temperature does potassium availability in the soil play a major role in the winter  resistance  of  many  species.  Potassium  is  not  found  in  any  organic compounds in the tree, but is present in cell and tissue fluids. A fertilization trial was started in 1978 in Siljansfors Experimental Forest. The plots in the experiment were fertilized with different amounts of potassium and one plot was  left  without  fertilization.  All  plots  that  were  fertilized  with  potassium  grew considerably better than the unfertilized plot. The difference in production between the unfertilized plot and the plot that received the most potassium was 7.2 m3sk/ha and year. The unfertilized plot can still be classified as waste land. The theoretical production capacity was estimated using a Swedish system for site quality  estimation  of  wetlands  after  ditching  (dikningsbonitering).  The  plot  with most  potassium  produced  after  fertilizationaproximately  in  level  with  theoretical estimations.  Key  words:  Peat  land,  Fertilization,  Ditching,  Growth,  site  quality..

Holmen Skog, region Norrköping, is located in an area with good potential for backhauling because a large number of geographically scattered mills. However, despite these factors there are many difficulties preventing the realization of this potential. The purposes of this study were twofold. First, from a hauling contractor perspective, to calculate backhauling profits and suggest a profit sharing scheme. Second, to identify and quantify obstacles and possibilities for realization of backhauls.The study required the use of three different types of methods.

Som grund för denna uppsats ligger en tidigare undersökning med titeln Undersökning av mental arbetsbelastning under instrumentflygövningar (Andreas Johnsson, 2004). Denna uppsats utgör en fortsättning på ovan nämnda undersökning. Liksom i Johnssons (2004) undersökning har en subjektiv mätmetod baserad på en niogradig skala använts för att utvärdera svaren på den enkät som använts för att få fram data. I denna uppsats undersöktes samma kurs som i den tidigare undersökningen. Det vill säga studenterna i kurs 03:2 vid Trafikflyghögskolan, Lunds universitet.

A growing need to strengthen ones position on the market, even as a city in competition with other cities, has resulted in an increasing number of municipalities developing brand platforms. When the city of Umeå developed their platform, they identified decision makers and investors as one of four important target groups.The aim of this study is to explore the portrayed image of the city of Umeå in two Swedish trade journals which addresses the specific target group decition makers and investors in both public and private sector. The aim is also to compare the image of Umeå in the two papers, to the ambition of the municipality, expressed in the brand platform.In order to make the observations as firmly established as possible, the method of the study is a combination of a quantitative content analysis and a qualitative text analysis. The study draws on the theories of Eli Avraham and Philip Kotler, concerning how to improve city images and how to market a specific city among others. The study shows that the city of Umeå in large extent is portrayed in accordance to the ambition which the municipality expressed in the brand platform.Umeå is displayed as an expanding city.

Industrial buildings are increasing all over Sweden. Farmers are building new modern facilities and the government chooses to build new halls to invest i youth sports. Glulam is the most common framework but there are limitations because of the transport. Therefore, there is a need to develop new solutions to increase the use of glulam.The maximum torque in the eaves was found in the frame with a roof pitch of 18 degrees and a wingspan of 25 meters. Using hand calculations according to Eurocode and comparison with the computer software StatCon, the maximum torque, shear force and utilization rate is calculated.

I rapporten beskrivs sjöfartshandeln i stora drag för att sedan fokusera på mer tekniska detaljer, så som hur propellermodellering fungerar och ett bulkfartyg avsett för att frakta sågat virke mellan Gävle och Hull projekteras. Senare i rapporten studeras möjligheten att utvinna olja och gas i arktiska områden.I propellermodelleringen beskrivs teorierna och metoderna för att beräkna fram en optimal fartygspropeller. Kombinationen av bladelementteorin och momentteorin för att erhålla rimliga beräkningsresultat redogörs och används sedan för att göra ett rimligt propellerval till fartyget som projekteras.Vid projekteringen av ett bulkfartyg efter transportscenariot dimensioneras ett fartyg avsett att klara av transportuppgiften. Rimliga mått bestäms för att fartyget ska klara av att frakta den givna lastmängden. Stabilitets- och motståndsberäkningar görs samt val av propeller och motor.
