Förnybar energi ur ett kvinnligt och manligt perspektiv : En attitydundersökning med avseende på att kartlägga hur synen på fönybar energi påverkas av om individen är kvinna eller man
Abstract The extraction and usage of energy give rise to immense environmental problems which helps to accelerate climate change. Energy is an important resource for the community and there are a variety of different types of energy sources available, that are either classified as renewable or non-renewable energy sources. The usage of renewable energy sources cause less environmental impact than the usage of non-renewable energy, which in turn means that the energy?s strain on the environment is strongly affected by the type of energy source used.The aim of the study is to describe to what extent attitudes towards renewable energy are affected by whether the individual is male or female, by examining the hypothesis regarding how women have a closer connection to nature and to a larger extent shows on an pro-environmentally friendly behavior than men, and if it also can be detected on issues related to renewable energy and thus imply that women have a friendlier approach towards renewable energy than men. A number of ecofeminist believe that women have a stronger bond with the nature through her embodiment as a woman and by her maternal role, which according to previous research also leads to the fact that women shows on a more extensive environmental behavior.Through a qualitative research method in the form of semi-structured interviews has three female and three male respondents been asked questions with regards to the environment, individual responsibility and energy.

Organisationen, ledaren, individen: vem ansvarar för hälsan? En kvalitativ studie om det hälsofrämjande och ohälsoförebyggande personalarbetet i Malmö stads stadsdelar.
The purpose of this study was to examine health promotion and ill-health prevention in the workplaces of the City District Committees in the City of Malmö. More specifically, we wanted to find what types of health problems there were and what kinds of strategies were applied to prevent them. Furthermore, the aim was to examine whether the leaders of the City of Malmö saw any effects of the strategies in use and if so, which. Finally, the intention was to compare our empirical results to previous research in the field of health promotion and ill-health prevention in workplaces. We conducted a qualitative study consisting of semi-structured interviews with five leaders in different levels, two personnel secretaries, two employees assigned to improve the health of the personnel in the City Districts, and one safety representative.
För ung för att dö : En litteraturöversikt baserad på yngre patienters tankar om hur de hanterar att leva med cancer
Background: Approximately one in three Swedish people will receive a cancer diagnosis. Cancer primarily affects the elderly but also young people suffer. Young people are in a period of life that could put a strain of the ordinary when they are faced with choices and new challenges. The basic sense of security in everyday life is not so obvious and many suffer from, for example, stress and the feeling of being inadequate in relation to the requirements. It is relevant that the nurses can put themselves into what it is like to be young and afflicted with cancer, with the pressures of life itself and what the disease represents.
Why does trehalose not improve autophagy in the SOD1G93A transgenic mouse model of familial ALS?
Amyotrophic lateral sclerosis is one of the major neurodegenerative diseases, causing an ascending paralysis that usually kills the patient within a few years from disease onset. The motor neurons show aggregates of proteins which in approximately 20 % of cases of the familial form contain mutated SOD1 protein.
Trehalose is a disaccharide which has been shown to reduce protein aggregation and increase viability in cell models and alleviate symptoms in animal models of several neurodegenerative diseases associated with protein aggregation. When given orally to the SOD1G93A mouse model of ALS, trehalose failed to slow down the disease progression, which has led to questions about the uptake and distribution of the molecule in this mouse strain.
The aim of this study was to investigate whether significant levels of trehalose reach the central nervous system of the SOD1G93A mouse after oral administration. This was performed by a trehalose assay of the brain of trehalose treated animals. A glucose assay was optimised for use in small samples of brain lysate after the digestion of trehalose into glucose by trehalase, and the difference in glucose concentration before and after digestion represented the trehalose level.

Psykisk ohälsa - eller ändå inte? : om hur ungdomars psykiska ohälsa har förändrats i en tid av välfärdsnedskärningar och kulturell modernisering
In recent times statistical findings suggesting a deteriorating mental health among teenagers, have been published. Not only did I find the lack of an all-inclusive analysis problematic, but also the fact that the studies themselves where often insufficient. Thus my purpose has been to chart these statistical studies, and then scrutinize the results.My method has been inspired by critical theory, where an interpretive starting point, self-reflection, and the idea that man and society interacts as a whole, is of great importance. Aside from the above mentioned studies, I have also employed secondary empirical data from TV, newspapers and the Internet. My own experience as a social worker has also been an important resource for this paper.
Comparison of three IVC systems for mice, with focus on growth and nest building in juvenile mice
Today the individual ventilated cage system (IVC-system) is the most commonly used system when housing rodents. IVC systems are designed to control both supply and exhausted air at cage level, as well as temperature and relative humidity in the cages. This creates an optimal environment for the mouse and at the same time a protection against the risk of cross-infection between cages and the outside environment. The aim of this study was to evaluate the health and welfare for two different strains of laboratory mice (NMRI nude mice and C57BL/6NCrl mice) in three different kinds of IVC-systems; Arrowmight, Allentown and Tecniplast. 108 mouse pups from each strain (in total 216 mice) were selected after weaning at an age of three weeks and tested during 5 weeks.
Att vänta på en hjärt- eller lungtransplantation - Ur ett närståendeperspektiv
Bakgrund: Hjärt- eller lungtransplantation håller idag på att bli en allt vanligare behandlingsmetod när den medicinska behandlingen inte längre har någon effekt på det sviktande organet och patientens liv hotas. För patienten och dennes närstående innebär hela transplantationsprocessen mycket lidande, ångest och oro. Ofta har de närstående en mycket viktig och ansvarsfull roll i patientens omvårdnad under väntetiden. Det är därför av stor vikt för sjuksköterskan att ha kunskap om hur hon på bästa sätt kan stödja, trösta och hjälpa dessa närstående. Syfte: Syftet med denna litteraturstudie var att identifiera och beskriva upplevelser av att vara närstående till en patient som väntar på hjärt- eller lungtransplantation för att få förståelse för hur sjuksköterskan kan ge stöd och hjälp.Metod: Litteraturstudie som bygger på nio vetenskapligt granskade artiklar.
Förekomst av Klebsiella pneumoniae i avföring hos mjölkkor : en riskfaktor för mastit?
Cows affected by mastitis caused by Klebsiella (K.) pneumoniae often become seriously ill. In some cases herdproblems may occur. Contaminated bedding material is considered to be one of the most common risk factors for klebsiella mastitis. In a recently performed study in USA it was found, however, that more than 80 % of healthy, lactating dairy cows excreted K. pneumoniae in faeces.
Samband mellan upplevd stress och självtillit på arbetsplatsen : En studie utförd på kvinnor i arbetsrelaterade situationer
SammanfattningSyftet med denna studie var att söka samband mellan upplevd stress och självtillit hos kvinnor i arbetsrelaterade situationer. Frågeställning: Finns det ett samband mellan upplevd stress och självtillit hos kvinnor i arbetsrelaterade situationer? Vår hypotes var att det finns ett samband mellan en kvinnas upplevda stress och självtillit i arbetsrelaterade situationer.För vår undersökning krävdes att vi kan mäta två variabler; stressnivå och självtillit hos en individ. Vi har genomfört en kvantitativ studie där vi har använt oss av en webbaserad enkät. Vi har valt att studera yrkesverksamma kvinnor och har tillfrågat 100 kvinnor som alla har någon form av relation till oss.
Förändring av pappersegenskaper vid lagring under dragspänning
SammanfattningI en pappersrulle är de yttre lagren utsatta för dragspänning. Om det finns variationer i rullens diameter i form av valkar finns det risk för att papperet förlängs irreversibelt i dessa positioner och orsaka slappa stråk. Den deformation som uppstår vid långvarig belastning av papper kallas krypning.Uppgiften i detta arbete var, att på lab., simulera valkar genom att utsätta pappersremsor för konstant dragspänning av olika storlekar. En av frågeställningarna var om egenskapsförändringar kan påvisas när papper utsätts för konstant inspänningskraft under en längre tid. De parametrar som undersökts var töjning, kryphastighet och relaxation, även mätningar på papperets mekaniska egenskaper dragstyrka, brottöjning och dragstyvhet har utförts i detta arbete.De papperskvalitéer som undersöktes var 71g/m2 MG-papper, 80g/m2 optisk liner och 135g/m2 liner.
Aktiv lastbilsstol för bättre förarergonomi och hälsa
The project concerns a predevelopment work for Scania AB, a leading manufacturer of heavytrucks, and was performed as a master thesis work for the program Design and ProductDevelopment at KTH. The purpose of this work was to examine how the work situation of truckdrivers, especially long-haulage drivers, can be improved with respect to prolonged sedentaryoccupation. Mental fatigue and under-stimulation due to low cognitive load during long drivescan be major risk factors for traffic accidents. Physical strain injuries to both the skeleton andmuscles are common for this working group and minimal opportunity for daily exercise alsoincreases the risk of developing blood clots in the legs, which can have serious consequences forthe driver's health.An extensive background study, both theoretical and exploratory, was performed to identify thedrivers' concerns and comfort needs. Various treatments such as massage and active sitting wereinvestigated and existing products within the area studied.
Fysiologi och beteende hos golden retriever i hemmiljö och under en testsituation
To fit into our society the dogs of today need a good mentality. To investigate their mentalitydifferent behavior tests have been developed. The tests are useful tools in the selection ofbreeding animals as well as for working and companion dogs. To counter the demand for atest that could be suited for all kind of dogs, regardless of their future function, the mentalitytest Beteende- och personlighetsbeskrivning hund (BPH) was developed. BPH consists ofseven subtests that expose dogs to various situations that can be found in everyday life, suchas meeting an unfamiliar person, sudden noises and suddenly appearing objects.The aim of this study was to find out if there are differences in physiological values betweenindividuals, validate the behavior observations during BPH and get aware of how the dogsexperience the situation.
Lactobacilli in the gastrointestinal tract of dog and wolf : isolation, identification and characterization of L. reuteri
Since the first wolf was taken as a companion animal a lot have happened with the biology of these animals. Is it possible that changes in the gut microbiota of the domestic dog are involved in the increasing numbers of animals with gastrointestinal disorders? Probiotics have been proven to promote the immune system of dogs by increasing concentrations of neutrophils and monocytes, decreasing the fragility of erythrocytes and increasing the serum IgG concentrations. Probiotics have also been shown to improve the fecal consistency, fecal dry matter and defecation frequency of dogs. The aim of this study was to find out if the bacterial counts in the gut of dogs differed from the gut of wolves, with the focus on lactobacilli.
