Att leva tills man dör - En litteraturstudie om vad livskvalité är för döende cancerpatienter.
The purpose of the study was to discover how nurses can maintain a good quality of life for cancerpatients at the end of life. We examined seven scientific articles in accordance with Polit, Beck & Hungler (2001) criteria for scientific validity. We used Carnevali's (1996) model of demand and resources as a frame of reference. The results showed that physical, psychological, social and spiritual needs affect quality of life in different ways. It also came out that it was difficult to measure something as individual as quality of life..
Klosjukdomar hos hund : en litteraturstudie och en fallstudie i den Svenska Riesenschnauzerpopulationen
Various problems with nail disorders have been noticed in the Swedish population of Giant Schnauzer, but the frequencies of these problems are unknown. This could be due to the fact that bad nail quality has several differential diagnoses and lack of diagnostic criteria and diagnostic codes for nail disorders. The main purpose of this study is to review different types of claw defects and diseases of the nail bed in dogs, and to classify and evaluate the proportions in the Swedish Giant Schnauzer population.
The nail is a specialized part of the skin. The quick will strengthen and protect the third phalang against the surrounding.
Effect of liming and free Ca2+ on Cd uptake of carrots, Daucus carota
The level of cadmium (Cd) in Swedish arable land has increased during the last century and the average concentration of Cd in the plough layer is today 0.23 mg/kg. The increase is mainly due to anthropogenic activities such as phosphorus fertilizing, liming, import of feed, and atmospheric deposition from industrial emissions. Cadmium in the soil will be taken up by crops and is thereby transferred to humans via food. Carrot is one of the crops of concern, both because it may contain quite high Cd concentrations and due to the large consumption in Sweden. In the body, Cd is stored mainly in the liver and the kidneys and may cause several diseases already at low concentrations.
Energieffektivisering av luftningssteget på Käppalaverket, Lidingö
This master thesis in energy optimization was made during the autumn of 2006 at Käppala wastewater treatment plant in Lidingö, Stockholm. A preceding thesis, where all electricity consumption was mapped, showed that the aeration in the biological treatment is the single largest consumer in the plant, and it is therefore of interest to reduce this cost. The oxygen control strategy used at Käppala WWTP is working well from a nutrient removal point of view, but not from an economic one. The last aerobic zones have a very low oxygen consumption during low loading periods which give rise to enhanced dissolved oxygen concentrations with excessive costs and reduced denitrification as a result. But also during periods of normal loading unnecessary high oxygen concentration are sometimes given.By modifying the aeration control strategy three full-scale experiments have been made, with the intention to reduce the air consumption.

Nationella prov - stöd eller hot? : Några gymnasielärares uppfattning om de nationella provens betydelse
The purpose of this study is to analyse the significance of the national assessment in highschool education, including what the teachers express about the new instructions currently coming from the Swedish National Agency of Education, concerning a more central control of grading the national assessments. This study also covers the teachers individual responsibility when it comes to grading the national assessments. The purpose of the national assessment is to secure that grading and the education level in the country is equal. This is a qualitative study useing the method of a group discussion intervju (focusgroup intervju). Five highschool teachers took part in the discussion with questions that had been decided beforehand.
Ekonomiskt bistånd - ett genusperspektiv på socialtjänstens bedömningar och beslut : En vinjettstudie i tre kommuner
Income support is often described as the community?s farthest protection, as a last economic way out. From the clients perspective it´s very important to get possibility to an equivalent and correct assessment. Even if it´s an individual assessment the individual social worker´s assessment should not be different than other social worker´s, this from two aspects ? quality and the rule of law.
Biologiska bekämpningsmetoder i hemträdgården :
Biological pest management is defined as control of pests using their natural enemies. This method has been used in Sweden since the 1970´s and it has been developed ever since. Biological pest management is today relatively common among commercial growers but there are good possibilities to apply this method in the home gardens as well.
The aim with this thesis is to compile a report from both the companies that are marketing the products and the home gardener´s point of view. This should give a better understanding of the market and how it could be improved.
We will give examples of products that represent the different kinds of organisms that are being used in biological pest management. Our hope is that this will be an introduction to all interested in biological pest management.
The legislations regarding registration of organisms are still a matter of discussion and are causing problems to producers, distributors and the market in general.
Why isn´t biological pest management more common in the home garden? The main reason appears to be the lack of knowledge in the subject.
What are the benefits using biological pest management when it requires so much knowledge and it´s more expensive than conventional pest management?
With the environmental problems we face today, we hope that every single gardener has an interest in developing an environment as clean as possible, even if only in one's own backyard..
MÄTNING AV LJUDIMMISSION FRÅN VINDKRAFT. VIDAREUTVECKLING AV METOD FÖR MÄTNING
The Swedish government have a goal that wind turbines shall produce 30 TWh by the year 2020, compared to about 3,5 TWh produced in Sweden during 2010. To minimize the disturbance that wind turbines create the Swedish Environmental Protection Agency has stated a guideline value that noise from wind turbines at nearby residents shouldn?t exceed 40 dBA, at 8 m/s wind speed. With advanced calculation models, like Nord 2000, the emitted sound from future wind turbines can be calculated at an early stage to optimize the power production without exceeding the 40 dBA. When the turbines have been built there is a need to verify that they really are within the guideline.
I vilken utsträckning kan hästar enbart utfodras med grovfoder?
Horses are grazers with a digestive system that is adapted for a high fiber diet. Forage is a fiber rich feed that includes grass and legumes. A deficiency of forage and an excess of grains may cause gut disturbances and stereotypic behavior. The aim of this literature study was to summarize information on the horse?s capacity to consume forage-only diets with focus on the horse?s need of energy and protein.
The efficiency of the newly launched predatory mite Amblydromalus limonicus : biological control of thrips in cucumber
In this study, the efficiency of a newly launched predatory mite, Amblydromalus limonicus, has been
examined for its potential to use as a biological control agent in cucumber production. A. limonicus
can be used for biological control of two thrips species, Frankliniella occidentalis and Thrips tabaci.
Field trials were conducted in greenhouses of two conventional cucumber growers in Scania, the
southern part of Sweden. The basic control agent used against thrips was the predatory mite
Amblyseius swirskii. In selected areas, additional A.
Nutrient effects on microorganism communities in nutrient poor soils
Better, more efficient fertilizers with great productivity and economic returns are needed, but it is important today to find fertilizers that are also sustainable. It is also important to carefully monitor their impact on the environment, including potential side-effects. In this context, the microbial communities that carry out numerous essential functions contributing to a functional ecosystem are of particular interest.
The present study is a complement to a pot experiment that investigated the potential of different waste products for use as fertilizers and how they affect the microbial community. In the pot experiment, the clearest treatment change in microorganism community function was found in the fully fertilized treatment used as a positive control. The question was whether this was indirect, i.e.
It is easier to swallow an elephant in pieces. A way of measuring flexibility and quality. A study of DAS.
Upon marketing the system in Europe and the USA cost savings generated from reduced work force have been prevailing. Since the cost of labour is much lower in the Asia Pacific region other factors have to be stressed. The parameters of flexibility and quality assurance may however cover any initial investment in a production system. Our purpose is to value flexibility and quality in a manufacturing context, applied to DAS, in order to use it in investment calculations. In order to make an adequate estimation of different companies, due to problems associated with acquiring correct figures, the Key Success Factors needs to be examined so that the gathering of numbers can be conducted with more focus.
