In this Master thesis, microwave connections between circuit boards are constructed. The primary frequency band is the X-band (8-12 GHz). The purpose of the connections is to enable a more simple and cheaper way of mounting the circuit boards inside a container. The connections have been designed and evaluated, using different computer programs. A few prototypes have been built and measured.

The Scanian woodfences has been determined by two mainly elements: Scania's composition of tree species, with a large element of deciduous forest, and the local building tradition which has more in common with the European continent than the Swedish tradition. By examining responses from ethnological question lists deriving from the first half of the 1900s, combined with literature studies, I have been able to deepen and broaden the knowledge behind the various fencing design. In addition I ?ve constructed maps which could illustrate their historical geographic distribution.I have come to the conclusion that there was three main types of woodfences that was most common until the barbed wire was introduced in the early 1900s and later on replaced the elderly woodfences. Common for the three main types is that the base material was made out of Juniperus communis, this largely because of its durability against rot.

SCA är Europas största skogsindustrikoncern. Fem bruk är lokaliserade i norra Sverige medan marknaderna för dessa bruks produkter är i Skandinavien samt övriga Europa. För att kunna konkurrera med de europeiska bruken är det mycket viktigt med en effektiv och pålitlig distribution. Då orderstorlekarna blivit mindre, lastning av arkat papper sker på pall samt att krav på regularitet och kortare ledtider ökat ansågs det gamla distributionssystemet vara förlegat. Ett helt nytt distributionssystem utarbetades i samarbete med MoDo.

The purpose of this study is to examine in what extent primary school teachers, teaching children in the age of 6 to 9, choose to use digital tools in their teaching of mathematics. I also want to examine what these teachers think, in terms of advantages and disadvantages, about using digital tools on their mathematics lessons. Finally I want to examine what skills they possess about digital tools.I am using a quantitative method to collect my data. The quantitative survey consisted of a questionnaire survey of ten questions that 38 primary school teachers have answered.The results of my study show that the teachers to some extent use digital tools when they teach mathematics and that the availability of various digital tools are generally good. But it turns out that the availability of tools is not a guarantee that they are used in teaching of mathematics.

The purpose of this thesis is to examine the debate in library journals and in official reports on the subject of library education in Sweden. We focus on two periods: the period just before the year 1972 ? when the library education was transformed into being occupationally-oriented and the period just before the year 1993, when the library education was transformed into being ?academised?. This Master?s thesis shows that the debate and the arguments among initiated people in the library world have had some impact on how the library education was transformed later on.

Syftet med studien var att studera vad för tankar personer iledningsfunktioner i olika elitidrottsklubbar har på strategier föratt utveckla sin personals kompetens bland styrelseledamöter,kanslipersonal, tränare och lagledare. Studien är av kvalitativmetod, åtta idrottsklubbar från fyra olika idrotter har medverkat.Elitklubbarna övergår alltmer från ideellverksamhet tillkommersiell verksamhet, vilket tvingar klubbarna till att ökakompetensen inom föreningen. Kompetensutveckling sker främstgenom utbildningar och via samarbete med andra klubbar.Kunskap som framkommit i studien; var att arbetet motkompetensutveckling på personalen var mycket brett inom detidrottsliga men desto mindre utvecklat inom marknadssidan.Förslag till fortsatt forskning är en studie med större urval frånfler idrotter och idrottsklubbar samt ett bredare geografisktområde såsom Skandinavien, Europa eller Amerika..

Aspen (Populus tremula L.) and goat willow (Salix caprea L.) are two important tree species in the aspect of nature conservation. Due to the elimination of forest fires, a former negative attitude towards deciduous trees in forestry and a strong herbivore pressure, these tree species have been negatively affected during the last fifty years. The aim of this study was to investigate whether the occurrence of aspen and goat willow could be related to either human impact or to site properties, such as ground moisture and vegetation type. A side study included an inventory of a number of cyanobacterial tree lichens on aspen and goat willow in order to try to relate the occurrence of these lichens species to stand history and stand properties. The study was performed in Hamra State Forest in northern Dalarna. Nature reserves were compared with stands in managed areas.

The gas turbines in the Swedish secondary reserve are reaching the end of their technical lifetime, hence alternative solutions need to be considered. One of the solutions thought to have the greatest potential is the use of so called consumptionreduction. By entering contracts with large consumers, agreements are made to reduce consumption in the event of major disturbances in the power system and thus being used as a secondary reserve. This thesis investigates the feasibility of consumption reduction as part of the secondary reserve. This has been achieved by developing a requirement specification for the disturbance reserve and by studying the technical and economic potential for consumption reduction among a range of consumers.The technical potential for consumption reduction that fulfils the requirements for participating in the secondary reserve are on average 750 MW in SE 3 and 98 MW in SE 4.

Superficial digital flexor tendon injuries are common causes of premature retirement or pre-longed convalescence periods for race horses. The curve gradient at Täby Galopp race track is very small and most races as well as high speed training are done on the left rein. It is believed that the horses left foreleg is under considerably more strain then the right foreleg when being ridden on the left rein during gallop at high speed. During gallop on the left rein the horse puts its entire weight on the left foreleg when regaining ground contact. The purpose of this study has been to find out, through analyzing the statistics concerning the horses that visited the ATG clinic at Täby during a period between January 2003 and September 2006, whether there is a higher frequency of superficial digital flexor tendon injuries on the left leg rather than the right and if so, can this support the theory that the design of the race track in combination with continuous left rein races can be a contributing cause of these injuries. The result of the study shows that 57% of the tendon injuries occurred on the left front leg and 38% on the right front leg. The difference is not large enough to support the above theory of the underlying cause of these injuries..

People in today?s society are becoming more and more aware of how important it is to use energy as efficiently as possible. This is clearly noticeable by an increase in home produced heat with e.g. solar panels or heat pumps heating systems. These changing customer demands forces district heating technology to be redesigned, which is why there is an ongoing research regarding the next generation of district heating - low temperature district heating (LTDH).

Energy supply in Sweden year 2011 amounted to 577 TWh. The final energy consumption for industrial, residential and service was 379 TWh. Sweden has energy policy goals to reduce energy use in buildings. One of these goals is to reduce the energy use by 20 % in 2020 compared to the year 1995. An important step to achieve this goal is to target energy efficiency measures in existing buildings.

AbstractHudiksvalls coordinating model - a model to make cooperation easierCamilla Andersson and Åsa GradinThe purpose of this study was to examine the experience each one of the administrators have of their own new model in Hudiksvall to make cooperation easier for the three different administrations in Hudiksvalls municipality. The study will focus on the administrators experiences of Hudiksvalls coordinating design. Questions of the study were: How is the influence of the model on the rules? How is the influence of the model on expectations and parts? What kind of influence did the model have on the responsibility distribution? What kind of influence has the model on the responsibilities at the transfer of costs? To answer the questions of the study we applied a qualitative method, it was made through a standardization interview guide and open questions, with six of the dealing officers who works with the model. Some of the results wich can be discern are by an economic character, andfor the clients that they won`t be passed around the administrations in the community, they get the right help, quick and safe.Key words: cooperation, coordination..

The aim of this study was to find out how journalism students at two universities in Sweden, Gothenburg University and Linnaeus University in Kalmar, use the social networking service Twitter. We were primarily interested in whether the students are using Twitter as a journalistic tool, which includes gathering, production and distribution of material. The study focused on journalism students because they soon will enter the working life and therefore can provide an indication of whether Twitter is a part of the future of journalism. We have used theories of mass communication to describe the development in the area and explore how journalism has adapted to this change. The study was conducted in the form of a survey in which the students answered questions about how they use Twitter and what they think about the social networking service.

Denna utvärdering av Umeå universitetsbiblioteks (UB) övergång till RFID-teknik (radio frequency identification) tar upp hur personalen har upplevt konverteringstiden och övergången. Syftet var att undersöka den involverade personalens åsikter och attityder kring omställningen och de eventuella konsekvenser och effekter som RFID-övergången fört med sig.Undersökningen genomfördes med korta uppsökande intervjuer vars frågor utformats i samråd med Umeå universitetsbiblioteks projektledare för RFID-konvertering. Frågorna resulterade i kvantitativa svar men respondenterna gavs möjlighet att utveckla sina svar med egna reflektioner. Av de totalt 17 respondenterna var nio män och åtta kvinnor i åldrarna 32-64 år. Resultaten visar på en till stora delar nöjd respondentgrupp, majoriteten tycker att övergången till RFID har fungerat bra, de flesta känner sig opåverkade i sin yrkesroll efter införandet och endast ett fåtal har lämnat konverteringstiden med några bestående men som drabbat deras arbete eller de själva. Bland respondenterna finns det en generellt positiv inställning till RFID-teknikens framtid på arbetsplatsen och ett flertal hoppas på en vidareutveckling och utbyggnad av tekniken..

The 22q11.2 deletion syndrome is a common genetic disorder that affects for example the heart, palate, immune system and hearing and therefore affects a child?s development. The purpose of this study was to investigate the proportion of children (0-18 years) with 22q11.2 deletion syndrome who have a hearing loss. A retrospective study of 103 children diagnosed with 22q11.2 deletion syndrome was conducted by medical records. Of the 103 children, 51 were boys and 52 were girls.
