Hypertrofisk kardiomyopati hos Maine coon katter :
Hypertrophic cardiomyopathy (HCM) is the most common heart disease in cats. Maine coon is one of the breeds where the disease is overrepresented. Studies have shown that HCM is inherited as an autosomal dominant trait in Maine Coon cats. This finding has led to cardiac screening using ultrasound in the breed. The results of the screening are used in a national breeding program constructed to reduce the spread and incidence of HCM in Maine Coon cats.
The effect of domestication on insect resistance in cotton : bioassays with the insect herbivores Spodoptera littoralis and Agriotes spp.
A plant's defensive ability against herbivore attack can be influenced by many different factors, one of them being domestication. During human selection to improve the yield of plants, the resistance against herbivore attack can have been lowered, due to a trade-off for use of resources between these traits in the plants.
In this thesis I investigated the effect of domestication on resistance against herbivorous insects in cotton plants. I used different varieties and species of wild and domesticated cotton in three different experiments. A feeding assay was conducted, the mortality, development
time and pupal weight of larvae of the Egyptian cotton leaf worm Spodoptera littoralis was studied. In a second experiment the preference of the root-feeding beetle Agriotes spp.
Död ved i vattendrag och kantzon, blå målklassning och NPK+ : en studie av förhållandena på Villingsbergs skjutfält
Idag pågår projekt med ambitioner att förbättra vattenhänsynen i skogsbruket för att uppfylla de svenska miljömålen och vattendirektivet 2000/60/EG. Sveriges skogsbrukshistoria har inneburit en allt mindre tillförsel av död ved till vattendrag. Dessa vedbitar fyller många olika funktioner i vatten då de exempelvis skapar habitat för många arter och medför ett mer varierat vattendrag. Denna studie är genomförd på Villingsbergs skjutfält, vilket förvaltas av Fortifikationsverket, och syftar till att ta reda på:
1) volym och antal (LWD, eng. large woody debris) grov död ved i vattendrag och kantzoner samt om volymen död ved varierar mellan olika strömordningar,
2) död ved fördelad på nedbrytningsklasser i vattendrag och kantzoner,
3) om den genomsnittliga dimensionen på död ved varierar mellan kantzoner och vattendrag,
4) beståndstyp i Fortifikationsverkets kantzoner jämfört med riksgenomsnittet, och
5) vilka styrkor, möjligheter, svagheter och risker verktygen blå målklassning och NPK+ har.
Resultatet från studien visar på en 5-9 gånger högre volym LWD i vattendrag jämfört med i kantzoner och 10-18 gånger högre antal LWD i vattendrag än i kantzoner.
Det sympatiska projektet : En kvalitativ studie om hur skillnader kostrueras i mötet mellan socialtjänsten och ensamkommande barn
The aim of this study was to examine how social workers relate to unaccompanied asylum-seeking children, regarding their cultural background and potential social issues. In order to achieve a more profound and comprehensive view of the social workers views regarding the separated children, we selected to execute semi structured interviews with social workers. These interviews were aimed at those social workers who performed assessments and investigations concerning unaccompanied children. We completed nine interviews which we recorded and transcribed in a strict manor. When we analyzed the empirical material, certain themes where identified as more protuberant and thus we our selection was based on what we regarded as the most relevant topics, in accordance to the aim of the study.
Vattendraget på Kåbo golfbana : en kartläggning som ett steg i golfklubbens miljöarbete
This degree project studied surface waters on Kåbo Golf Course in Uppsala, Sweden, with the aim of determining the status of the water and how it is affected by the activities of the golf club, and to obtain suggestions of measures to create better conditions for the water environment on and around the golf course. The project forms part of the environmental protection work of Kåbo Golf Club, which is working towards achieving environmental certification from the Swedish Golf Association (SGF).
The study is based on literature studies and quantitative and qualitative field studies of water on the golf course, with the focus on environmental factors identified as being important for the golf industry and on strategic environmental goals developed by SGF.
The number of open water bodies in the Swedish landscape has substantially declined during
the past 200 years, so it is important to save those that remain. This study showed that the surface water at Kåbo Golf Course is an important element in the surroundings since the area contains few wetlands, which can be a habitat for large numbers of species. The stream and ponds on Kåbo Golf Course also have the important function of serving as water hazards in the game and adding difficulty and variety to the course. Since Kåbo Golf Club wants its surface waters to look aesthetically appealing, extensive algal growth and drying up of ponds during parts of the year are regarded as problems.
Konceptuell design och utveckling av hybridfordon
This report covers the conceptual design of a new one person hybrid vehicle that is to be fast and convenient to drive on the roads. The vehicle is most of all supposed to be used as a commute vehicle but can also be used at other occasions as well.During the work with this project the group has focused on three larger areas, the outer design (body), wheel chassis and an ergonomically designed interior. The group was not able to just create these parts in 3D to get a trustworthy vehicle, hence number of other components and details were also created to get a better entirety.The outer design starts with idea generation and sketches and ends with a 3D model which is rendered to show how the final product is going to look. The design of the body has been going on during the entire work process due to new ideas and improvements that seemed interesting and had to be changed.The wheel chassis also started with idea generation, research and sketches. It ended up with a simulated 3D model which later on was mounted on the vehicle body to show how the vehicle is going to perform during usage.

Strindbergsbilden idag : En analys av åtta litteraturhistorier för gymnasiet
The purpose of this study has been to analyze the image of Strindberg in today's upper secondary school. How is the author portrayed in the textbooks and teaching aids, and which parts of the authorship does the textbook and teaching aids authors choose to focus on? This work has been implemented in the form of a textbook and teaching aids survey where eight textbooks for the upper secondary school from 1989 to 2008 has been analyzed with focus on the sections that consider Strindberg and his authorships.What emerges when studying these textbooks and teaching aids is that they give a rather synonymous picture of the man and the author Strindberg. Big focus is aimed on private life and the scandals that the author more or less voluntary became a part of. The majority of the textbooks treats matters as ?the misogynist? and ? the critic of society? and the so called Inferno crisis, and also when one discusses the literary works it is done in the light of the author's own life and accomplishments.When it comes to the author's literary production it is a very limited selection that is presented to the students.
