Design av mikrovågsövergångar

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.

Inhysningssystem för växande ungtjurar

The purpose of this study was, if possible, to find a housing system for growing bulls that was as optimal as possible for the animal welfare. In order to select housing systems you must take into account the size of the group, body weight and the type of floor. Seven of the international most common housing systems were compared, straw bedding, deep straw bedding, sliding straw bedding, concrete slatted floor, rubber coated slatted floor, cubicles and feeding cubicles. Studies that have examined the proportion of tail, claw and leg injuries and the presence of unnatural behavior in the different systems. In summary, all studies showed that soft underlay were beneficial for the animals in terms of the proportion of bone lesions and swellings.

Lärare och digitala verktyg i matematikundervisningen : En kvantitativ studie om lärares inställning och kompetens kring användningen av digitala verktyg i årskurserna F-3

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.

Var finns lekplatsen? : Ett examensarbete om orienterbarhet i en parkmiljö

Detta examensarbete har skrivits inom ämnet informationsdesign, som en del av kandidatprogrammet Informationsdesign med inriktning mot Rumslig gestaltning. Platsen som har studerats är Folkets park i Malmö, som i skrivande stund står inför en större ombyggnation. Detta examensarbete har både tagit utgångspunkt i parkens nuvarande, samt föreslagna utformning, vilket gjort att jag under processen behövt växla mellan dessa två olika perspektiv. Syftet med examensarbetet har varit att ta fram ett koncept som kan förbättra målgruppens möjligheter att orientera sig i parken efter den föreslagna ombyggnationen.  Genom teorier, platsanalyser och intervjuer har människors beteendemönster vid informationssökning i rumsliga sammanhang undersökts, med särskild fokus på hur detta kan fungera i Folkets park.

Debatten om bibliotekarieutbildningen ? inför förändringarna av utbildningen år 1972 respektive år 1993 ? sådan den återspeglas i bibliotekstidskrifter

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.

Samhällskunskap - ett ämne i tiden? : En studie av globaliseringens inverkan på samhällskunskapen

In preparation for the autumn term in 2011, the Swedish elementary school adopted newsyllabuses regarding,inter alia, the civic education (Sw. Samhällskunskap). The civiceducation has traditionally been a disciplinary subject with a main purpose of mediatingdemocratic values as well as providing general orientation in the society. Generally, the civiceducation intends to reflect the world in which people live in, being a complex society whichto a large extent is regularly affected by global aspects and developments.The purpose of this study is to review all the elementary school?s syllabuses relating to thecivic education with specific focus on the globalisation perspective.

Vad styr förekomsten av sälg och asp? : en studie av olika beståndstyper inom Hamra kronopark, Dalarna

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.

Kärnkraft : Ett arbete för drifttekniker?

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.

Fördelning av frambensskador på ytliga böjsenan hos galopphästar :

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..

Energikartläggning och driftoptimering genom behovsstyrning i befintlig fastighet

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.

Genusstrategier i förskolan : En studie av en förskolas arbete med att motverka traditionella könsroller, ur ett intersektionellt perspektiv

The purpose of this study is to examine a preschool's work to counteract traditional gender roles, which strategies are used and how norms about gender roles are produced and treated. The study also examines whether the preschool has an intersectional perspective in it's gender work, which analyzes how they relate to other categories such as ethnicity, race, class, age and sexuality in their work. I have been observing and conducting four interviews with teachers at a preschool with a gender profile. In my analysis I have used Foucault's theories about discourse and power. The results show that the informants had a high awareness of gender and that the main strategies used were: an individual perspective, seeing the individual and not the sex, and a gender-neutral strategy, removing everything that is gendered, for example, in language and environment.

Copingförmåga och copingstrategier hos patienter med KOL och patienter med hjärtsvikt : En kvantitativ, jämförande tvärsnittsstudie av patienter i primärvården i Sverige

Minst 500 000 av Sveriges befolkning har kroniskt obstruktiv lungsjukdom (KOL) och ungefär 250 000 har hjärtsvikt. De två patientgrupperna hade många likartade symtom och en sjuksköterskeledd gemensam primärvårdsmottagning för dessa patienter kunde innebära många vinster. Ett av distriktssköterskans kompetensområde var att ha stödjande samtal om hur den enskilde patienten hanterade sin sjukdom. Syftet med uppsatsen var att jämföra copingförmåga och copingstrategier mellan patienter med KOL och patienter med hjärtsvikt, samt att undersöka eventuella skillnader av grad av ångest, depression, påverkan på funktion av fatigue och andfåddhet utifrån copingförmåga och användande av olika copingstrategier.  Metoden var en beskrivande och jämförande tvärsnittsstudie. Patienter med KOL respektive hjärtsvikt från primärvården i tre landsting ingick i studien och de fick svara på en hemskickad enkät.

Det svenska alkoholmonopolet och fri rörlighet av varor

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..

Samband mellan målorientering, motivationsklimat, upplevd prestation och tävlingsrelaterad ängslan/oro hos ungdomar i alpin utförsåkning

Achievement Goal Theory (AGT) utgår ifrån att alla individer vill visa sin kompetens vilket tar sig uttryck i två målinriktningar; ego och task. Individen påverkas av omgivningen som driver ett motivationsklimat som kan uttryckas i samma typer av målinriktning. Motivationsklimatet och målinriktningarna anses påverka hur individen agerar och hanterar t.ex. ängslan/oro och prestation. Denna studie behandlar samband mellan individuella målinriktningar, upplevt motivationsklimat drivet av tränare, träningskamrater och föräldrar, tävlingsrelaterad ängslan/oro och upplevd prestation.

Meritpoäng eller skoj? : en undersökning om meritpoängens konsekvenser för ämnet moderna språk och framtiden

The main purpose of this C-essay is to answer the question: What have been the consequences and effects of the merit point system on language studies and the parties concerned (teachers, students and principals) during the school year of 2010/11?The merit point system is the result of a political decision and was implicated for the first time in the Swedish upper secondary school during the school year 2010/2011. Being a completely new phenomenon it is of great interest and importance to study its effects.The study in this essay also aims to verify, falsify or nullify two hypotheses very often referred to in the political discussions regarding the merit point system:The merit point system will replace affection and interest as main reasons for language studies in upper secondary school and cause a rectification amongst the students choices of additional courses.The merit point system will have a segregating effect upon society and make it harder for people to rise in society through education in the future.A verification of these hypotheses would imply the appearance of an increased rectification amongst students as well as an orientation towards an in the future more segregated society.The empiric material has been collected and examined with qualitative as well as quantitative methods (questionnaires and interviews) and belongs epistemologically to the phenomenological and hermeneutical traditions..
