Grävlingar : En studie om grävlingar i fångenskap, deras naturliga beteenden och fysiologi
I det här arbetet presenteras en studie från ett projekt som ägde rum i Kolmården djurpark sommaren och hösten år 2003. Projektet bygger på ett uppdrag från jordbruksdepartementet. Det handlade om huruvida grävlingar i fångenskap reagerar i olika stressande situationer. För att kunna undersöka detta har grävlingarnas naturliga beteende studerats under fyra perioder från juni till september samma år. Det som studerats under perioden är grävlingarnas olika beteenden, lokationen i grävlingshägnet samt fysiologiska parametrar så som hjärtfrekvens och kroppstemperatur hos grävlingarna.
Modellstudie av föroreningsretention i Bäckaslövs våtmark : Tillämpning av modellverktygen MIKE SHE WET och MIKE 21
During the nineties, ecological handling of urban storm water became very popular in Sweden. Together with Chalmers University of Technology and two Swedish communities, DHI Water and Environment has been doing research of storm water ponds and constructed wetlands. This thesis work is a part of that research project. The work has been applied at the Bäckaslöv storm water treatment plant in Växjö, Sweden. The plant consists of one storm water pond and a downstream constructed wetland.

Interventioner för livsstilsförändring avseende kost och fysisk aktivitet inom primärvården
Background: Ill-health related to unhealthy lifestyle is increasing and despite existing knowledge about healthy lifestyle it is difficult to change behaviour. Counselling in the primary health care is often superficial and without critical elements for behaviour change. Aim: The aim of this paper to elucidate interventions for change of lifestyle with respect diet and physical activity. Method: A literature review was carried out and ten scientific articles were analyzed and compiled in two main categories: design of these interventions and participation in them. Results: Education, decision making, goal setting, feedback, social support and follow-up were identified as critical elements for behaviour change.
H2 För racing
AbstractMotor sports have been around as long as motor vehicles have been. Sports are often seen as costly polluter but in the same time the motor sports have encourages a large part of development, both for vehicles and other industries. Inventions like rear mirror and ABS brakes come from motor sports. One way to once again drive development forward while making motor sports carbon-neutral is to run the race cars on hydrogen. In this thesis, the goal is to convert a spark ignition engine for hydrogen operation.
De leende kvinnorna : en jämställdhetsutredning av en mandominerad arbetsplats
This essay is part of a project between Södertörn University College and Stockholm Academic Forum. The focus of the project is gender equality in small- and medium sized companies. I have worked with a construction company called Activa . The majority of the employees at the company were male and I was interested in the consequences of gender construction in such an environment. I think that the basic condition for equality work is an understanding of gender and the male norm.
"Man vill ju se bra ut" : En kvalitativ studie om ungdomars syn på sociala medier
This thesis examines young people's thoughts about their presence on social media. With asocial constructive approach the study focused on how young people think and act on socialmedia in relation to constructions of gender and normality. The analysis is based on fourgroup interviews with 13-year old boys and girls. The theoretical approach is based partly onsocial constructionism where discourses and ideas of normality are identified and analyzed.Erving Goffman's theory of social interaction was central to illustrate how young peoplepresents themselves based on the prevailing discourses. It is clear that they adjust theirrepresentations of themselves depending on the context.
Utmaningar i den psykosociala arbetsmiljön - en studie av HR-arbete i ideell sektor
The purpose of this study is to conduce to the understanding of what challenges the HRdepartmentfaces in the work with the psychosocial work environment in nonprofit organizationsin Sweden. A particular focus in the study is on how the certain features of the nonprofit sectoraffect and tend to contribute to these challenges. In both Swedish and International research thereappears to be a lack of studies that deal with the psychosocial work environment in the nonprofitsector, which is one of the main reasons for this study. International research show, among otherthings, that employees in this sector have a higher degree of work satisfaction than in othersectors. Especially, they value the sense of making a contribution to the society, to get feedbackon their work performance as well as they expect a high level of co-determination.
ESC-analys och studering av knack på en "Diesel Dual Fuel"-motor
A one-cylinder research engine has been used for studies with a Diesel Dual Fuel concept (DDF). DDF is a concept that utilizes a pilot diesel injection to ignite a homogenous natural gas/air mixture. Emissions and engine efficiency have been analyzed in an emission cycle called European Stationary Cycle (ESC) and the knock/pre-ignition problems with this type of engine have been investigated.At low and mid torque levels, an early diesel injection around 60 crank angles degrees (CAD) before top dead center (TDC) was used. At these loads raw NOxemissions was below EURO 6 level (0.2 g/kWh). NOxwas at EURO 5 level over the complete ESC without after treatment and with SCR at high loads it should be possible to reach EURO 6.One issue with DDF is the high HC emission levels.
Barn CVK En systematisk litteraturöversikt
Syfte och frågeställningarSyftet med studien var att undersöka omgivningens påverkan gällande den totala upplevelsen vid gång och löpning. Detta besvaras genom frågorna; finns det någon skillnad i puls, ansträngningsgrad och positiva känslor vid samma hastighet gällande gång och löpning utomhus jämfört med inomhus? Samt, upplever testpersonerna någon skillnad fysiskt och psykiskt efter gång och löpning utomhus jämfört med inomhus? MetodDetta är en experimentell studie med kvantitativ metod. Tre olika tester har genomförts i studien. Det första testet var ett kontrolltest som avsåg att få fram den hastighet som motsvarade testpersonens Borg RPE20 på nivå 11, 13 och 15.
Professionell garantihantering : Ett arbete inom byggnadsbranschen
A business is always dependent on its customers. It is therefore important to ensurethat customers are satisfied with the product and the warranty included.The study was conducted in cooperation with the building contacting companySkanska Sweden. The aim is to use interviews to collect and process experiences in order to answer the question: How should the recovery process in the construction industry be performed to ensure a professional handling of warranty? The results have shaped my conclusions and I have turned them into a proposal that companies in the industry can benefit from. The study indicates that the industry is not geared for a five year warranty, which was introduced in 2004 and 2006.
Cystisk endometriehyperplasi/pyometra-komplexet hos hund : orsaker och patogenes
Virulent strains of Staphylococcus hyicus produce exfoliative toxins and cause a potentially fatal skin disease in piglets known as exudative epidermitis. Vaccines and antimicrobials are used to control the disease. Antimicrobial resistance and the prevalence of several different toxin genes and toxigenic strains make it problematic. The aim of this literature study was to identify potential differences between countries and between healthy and diseased pigs regarding antimicrobial resistance and toxin-producing strains. Great differences could influence vaccine production, treatment strategies and surveillance programs.
Jordbruk kontra industri : jordbruksregleringar ur marknadsstrukturmässigt perspektiv
What is the?self? and to become ?one-self?? To resolve this questions possibility I´ve been using the philosopher Søren Kierkegaard metaphysic paradoxes. This essay about the ?self? shows the reader the difference between describing a transcendent and immanent phenomenon and if it´s possible to become or to not become ourselves. The process is a key of the ?self? which Kierkegaard explains the ?self? in and for it-self.
Brukarmedverkan i förvaltning av tätortsnära naturmark :
Flera kommunala förvaltningar och andra instanser efterfrågar idag former för hur brukare aktivt kan involveras i skötsel av tätortsnära skog- och naturmarker. Erfarenheter finns, men delgivning av goda exempel och bra referenser är en bristvara.
Genom detta examensarbete presenteras en form för hur skötsel av en tätortsnära skogs- och naturmiljö praktiskt kan genomföras tillsammans med de boende i närområdet. Förslaget för samarbetet har utformats via en fallstudie och baseras på intervjuer med boende och förvaltare inom ett avgränsat villaområde i Huskvarna.
Studien redogör även för synpunkter och de krav som lyftes fram av respektive part inför samverkanssituationen, dvs. samverkanspotentialen och själva ramen för samverkan.
Våtmarker i urbana miljöer : växtgestaltning och planering
The practice of landscape architectural involves forming the space in our cities and suburbs, as well as the landscape surrounding. The need of exploiting green environment leads up to, among other issues, flood problem during heavy rain and overfed water environments. The problem is partially caused by the shortage of knowledge, how the environment is responding of the innovations made by the city- urban planning and how to get sustainability.
Research and knowledge how to take care of our environment, in a natural way, is increasing. The object of the thesis is to propose control and balance in urban wetlands, and discuss the difference a plant design can do.
The thesis deals with discourses in the field of landscape architecture, biological diversity, dam construction, limnology, planting design and management, pollution of the environment and urban design practice.
