During the last 50 years the production of milk per cow has increased. This has, however, been followed by a decreased reproductive performance. Shorter and more indistinct signs of oestrus make it harder for the Swedish farmers to discover when the cows are in oestrus. There is a need for ways to control reproduction. The use of pheromones could possibly provide means to satisfy this need.

Almost all Swedes today have access to the Internet, if not through the home then via the library or work. Despite this, around 20% of the population stand outside the information society in that they lack in knowledge, assistive usability tools or positive attitude towards technology and its influence on society. The main factors influencing the digital divide in today's society are age, disability and education, while the main reason for staying outside seems to be disinterest.The question about digital inclusion is important as we now stand on the breaking-point between a society where the industry has had a prominent position for private as well as national economy and a digital society where access to the Internet is no longer about prestige, but where significant differences between users' knowledge levels can create a power gap. Gaps in access and use not only reflects already existing socio-economic conditions, but can also maintain and enhance these.It is crucial for the future expansion of Internet usage how today's non-users feel about becoming users. To understand what underlies the motivations not to use computers is one of the keys to get non-users to embrace becoming users.

Blodtrycksmätning är en viktig del i en sjuksköterskas arbetsuppgifter och då både manuell och digital blodtrycksmätning idag förekommer parallellt inom svensk sjukvård syftar denna studie till att undersöka om det finns någon skillnad mellan de uppmätta resultaten i dessa mätmetoder och beskriva denna eventuella skillnad. Undersökningen genomfördes på en kärlkirurgisk avdelning på ett sjukhus i södra Sverige under hösten 2009. Populationen bestod av 38 inneliggande patienter som följdes upp med totalt 65 blodtrycksmätningar. För att utföra undersökningen tillämpades cross-over design med kvantitativ ansats. Resultaten visade skillnader mellan de två mätmetoderna då den digitala metoden uppmätte högre blodtryck än den manuella. Digital blodtrycksmätning visade genomgående högre mätresultat jämfört med manuell metod.

Undersökningens syfte var att öka vår kunskap om hur elever, i åldern 6-9 år, spontant beskriver materieuppbyggnad i fast och flytande form samt vad som händer då fast materia löses i flytande materia. Detta för att vi som pedagoger skall kunna stödja elevers naturvetenskapliga begreppsutveckling. Vi använde oss av enskilda kvalitativa intervjuer för att få svar på våra frågeställningar. Eleverna fick beskriva hur materia i deras vardagsmiljö är uppbyggd och vad som händer när fast materia ska lösas i flytande materia. Deras svar var till 90 % av ett makroskopiskt, kontinuerligt perspektiv.

Östersunds kommun behövde höjddata inför planeringen av ett nytt bostads- och rekreationsområde som kallas Storsjö strand där en ny fördjupad översiktplan tagits fram. Syftet med examensarbetet var att skapa en digital höjdmodell över en del av området. Mätningar med Leica GNSS-utrustning samt totalstation utfördes under några dagar.  Höjddatat levererades till kommunen. En triangelmodell skapades och en karta med höjdkurvor togs även fram för att visualisera arbetet. En del felkällor kan ha haft inverkan på resultatet såsom tjälen i marken och eventuellt några enstaka flervägsfel, men vi anser ändå att resultatet är tillräckligt för en första översiktlig planering..

The milk production per cow has increased considerably during the last 50 years and due to the breeding for higher milk production also brings decreased reproduction efficiency. In a Swedish study 1996 it was shown that on average only half of all estruses were detected. Every time a farmer fails to detect oestrus it costs the farmer about 1200 Swedish crones and the need of means of detecting oestrus is therofore large. With this study we wanted to investigate if heart rate respectively crystallisation of vaginal mucus (arborisation) could be useful means of detecting oestrus. We monitored two oestrus cycles in four heifers.

This degree project concludes the Innovation and Design Engineering programme at Karlstad University. The project was carried out by David Brocker, Erik Hallberg and Andreas Hertzman during the spring of 2006 and corresponded to 15 weeks of work per student. Assigner was Martin Larsson at Arexor and instructor at Karlstad University was Monica Jakobsson.Arexor has a patent to a construction of an electrical skirting board with moveable wall sockets, called Electrical Track System. The lowest parts of the interior walls along the floor are today almost always covered by a conventional skirting board. Arexors patented product replaces that with the possibility to move and increase the number of wall sockets by choice along an electrical skirting board.

Energy is an important issue in the current world which significantly affects sustainability and development. Energy generation and use are major sources of CO2 emissions which is one of the most important driving factors in global climate changes. The amount of energy used in house hold section can lead to estimation of the amount of CO2 emitted within this section which subsequently would be a ground to better management and maintaining a sustainable society. This study which is a bachelor?s project in sustainable energy, deals with estimation of CO2 emission from different types of residential houses in Sweden. An extensive literature review on energy use in Sweden by different residential sectors has been conducted.

Nedladdade spel har blivit mer förekommande än vad de var fo?r ett årtionde sedan. Bredbandets framgång har gjort det möjligt att snabbt ladda ner spel och marknaden fo?r digitala spel växer stadigt. I denna studie undersöker vi om konsolspelarnas attityd mot digitala konsolspel skiljer sig från fysiska konsolspel i och med den växande digitala marknaden.

Digital distribution för datorspel växer för varje år. Med tiden har fler och fler webbutikermed endast digitala produkter dykt upp, samtidigt som de gamla till en allt större del harbörjat erbjuda ett digitalt sortiment. Konsumenterna har med denna utveckling ett hav avolika typer av distributionsmöjligheter att välja bland. Vissa kan för en del konsumenterkännas restriktiva, medan andra webbutiker erbjuder en typ av försäljning som påminner merom den fysiska.Syftet med denna studie är att försöka identifiera de olika typer av affärsmodeller ochdistributioner som finns i dagsläget, och om det finns behov av att införa någon typ avstandard i form av riktlinjer och rekommendationer för digital distribution.Studien visar att det skulle vara problematiskt att tillämpa riktlinjer som skulle fungera ipraktiken för alla dessa varianter av digital distribution. Men samtidigt identifieras ett antalproblem som individuellt skulle kunna åtgärdas med hjälp av några av de riktlinjer ochrekommendationer som tas fram genom bland annat kvantitativ undersökning blandspelkonsumenter och intervju med Sveriges största aktör inom området..

On social media, girls create digital spaces where a distinctive spiritual culture emerges. This spiritual culture is therapeutic in nature, consisting of therapeutic compositions and happiness-generating templates that contribute to the girls' respectability by allowing them to take responsibility through their intuitive knowledge. The purpose of this study is to investigate how the pursuit of respectability is manifested in these digital spaces by examining spiritual expressions and exploring how participation in therapeutic culture online serves the attainment of respectability. The study employs a participatory netnographic method, focusing on observations of LIVE broadcasts on TikTok. In these broadcasts, girls engage in various spiritual practices within a shared digital sphere. The observations are analyzed through the theoretical frameworks of Beverley Skeggs' concept of respectability and theories related to therapeutic culture, including happiness culture and therapeutic assemblage. The findings reveal that both the girls hosting the LIVE broadcasts and those participating by commenting collaboratively create a digital culture through the exchange of advice.

A case study of professional interaction designers' usage of design materials was conducted. Five interviews were performed in order to gain insight in the systems used by designers, how these work, how they collaborate within them, and what they think of recent research about them. Design studios allow collaboration for several users at once. Digital material (mockups, pictures, etc.) are commonly used, but needs to be made analog, e.g. printed, to be usable in the design studio environment.

This research analyzed differences in measurements of magnetic field strength and frequency response in five audio induction loops installed in rooms of wooden construction materials and five audio inductive loops installed in rooms of steel reinforced concrete constructions. The inductive loops were installed at floor level and the measurements were made at the listening height of 1.2m. Measurements of background noise, field strength and frequency response were made at fifteen different measurement points across the room. The research measurements showed that there are differences in field strength and frequency response between these two conditions, whether the audio induction loop is installed in a wooden construction or the audio induction loop is installed in a reinforced concrete construction. The results had a significance level of p=0,05..

The aim with the project was to portray something to step on. Its purpose has been to experiment and explore the interaction between pattern, structure, material and colour for something to be applied on a floor. Focus has been on esthetic expression and not the creation of some¬thing for a specific environment or audience. My goal was also that this project would illustrate the importance of the floor to create a certain atmosphere in a room.The project was divided into three phases. The first one was the experimenting and exploring phase, where the goal was to find an expression.

The purpose of this study was to follow a research-oriented design process and to develop a design draft for a digital service that supports users to make more environmentally conscious choises in their everyday life. By following an interaction design process from start to final delivery, the study aims at creating a broad understanding of the process. Therefore, many userrelated activities were implemented in the study: eg. personas, scenarios, sketching and user testing. The project resulted in digital wireframes for an iPhone application using embedded GPS to identify and locate environmentally friendly businesses.
