Behandling av konfliktbestånd - problem och möjligheter :

Overdue cleanings have for a long time been an important topic of discussion within the forestry sector. When stands that have not been pre-commercially thinned are reaching the level of commercial thinning, many problems occur in terms of decision-making and economical outcomes. These types of stands are commonly known as conflict-stands. The work was carried out partly as an interview survey towards representatives from the forest sector and the energy sector, partly as a case study of conflict-stands situated in Böksholm, north of Växjö and in Tönnersjö east of Halmstad. The criteria for the studied stands were that they had to be dominated by Norway spruce and be in a severe status of ?conflict?. The aim of the interview was to get an overview of the situation today, and also analyse trends in terms of conflict stands.

Hur påverkar avlövad underväxt kvaliteten och drivningskostnaden i gallring?

Gallring är en beståndsvårdande utglesning där gagnvirke tillvaratas. Syftet med gallring är att styra över produktionen på ett lägre antal stammar och på sikt skapa ett bestånd med en högre medelstamsvolym än om gallring inte genomförts. Gallring kan utföras enligt olika former, vilket påverkar produktiviteten i drivningsarbetet och beståndets karaktär efter utförd åtgärd. I vissa bestånd kan det finnas ett undre skikt av löv eller gran som försvårar gallringen, så kallad försvårande underväxt. Den här studien syftade till att undersöka om underväxtröjning är en åtgärd som kan leda till att minska kostnaderna i gallring i bestånd med underväxt. En tidsstudie utfördes i två talldominerade bestånd med lövdominerad underväxt i 2-3 meters höjd.

Rationell riskanalys inom VA-verksamhet med avseende på säkerhet, hälsa, miljö och kvalitet

This master thesis is developed based on the desire of the water and sewage department in the municipality of Karlskrona. The department, which vouches for the quality of produced drinking water and sewage cleaning, was in need of help dealing with risk analysis.The water and sewage department is obliged to identify and assess risks according to Swedish legislation. However, no guides for this purpose regarding safety, health, environment and quality were available. The aim of this report was to accomplish a guideline for the performance of risk analysis within water and sewage plants. If the guideline is used, the requirements in the legislation will be obtained.

Inomhusklimat i skolor- En jämförelse mellan upplevt och uppmätt inomhusklimat

Students? performance in school is dependent on the indoor climate. This report studies four schools regarding air quality and thermal environment. A survey was made at the schools as well as measurements of carbon dioxide, dampness, thermal climate and, as an indicator for the furniture?s capability to collect dust, shelf factor and fleece factor.

ATP bioluminescence to establish a test procedure for hygiene testing of liners and tubes on farm level : an investigation of the effect of ageing on the hygienic status of rubber liners and tubes

When rubber equipment in a milking system ages, physical and chemical deterioration occurs and cracks, crevices, as well as deposits of organic and inorganic material is formed on the surface. Bacterial colonization can accumulate, especially on ageing rubber equipment and if the cleaning procedure is not functioning properly. Formation of biofilm in milking equipment could in turn cause bacterial contamination of bulk tank milk. ATP bioluminescence is a fast and easy way to determine the hygienic status of a surface based on its ATP content, and results are given in relative light units (RLU). The method measures both bacterial contamination as well as residues from other organic material.

Miljö- och hälsoskyddskontorets tillsynsarbete - ur verksamhetsövarens perspektiv

Nanofiltration is a proper way of preparation of drinking water. The process has a lot in common with reverse osmosis where a semipermeable membrane is used to separate a pure water flow from the remaining water. A pilot plant was used to ensure that nanofiltration is a suitable technology for a specific waterworks station in Glemmingebro, Ystad. The purpose was also to find out if a pH-adjustment is needed for feed water in a possible full scale plant.  In this case nanofiltration is used mainly to remove sulphate and calcium since the raw water contains concentrations of these substances which exceed the limits for potable water. It is important to receive a high recovery (RC), otherwise the deliviery of water won?t be high enough.

Anhörigvårdare - kommunens stöd till anhörigvårdare och deras behov av stöd och hjälpFamily caregivers - the municipality's support to family caregivers and their needs of help and support

The family and relatives caring for older people in Sweden lies on an old tradition. The responsibility to care for older family members has gone from family to the society. The aim of this study was to examine the needs of family caregivers and their experience of municipality support. This study includes only the family caregivers who have the main responsibility for the care of relatives and have support from the municipality. The caregivers were not allowed to work more than 50 percent in another job.

Kulturvårdscentrum 1986-2001

Kulturvårdscentrum was a project that had great significance for local folklore societies in Bohuslän.Bohusläns museum was i charge of the project that lasted from 1987 until about 2001 when most ofthe original staff have retired. The staff was mainly recruited from a large shipyard, Uddevallavarvet,at it's closure due to recession. Financing was largely made by the government to help outthose unemployed who otherwise should have a hard time finding a new job. At start there was about25 employees who where trained for one year by staff from Swedish museums, conservation studios,and teachers the university. The education was aimed at serving local folklore societies, and dealingwith their special problems.

Hur har införandet av automatiska mjölkningssystem påverkat juverhälsan hos mjölkkor och vilka riskfaktorer finns?

Today, there are more than 12 000-14 000 farms worldwide using an automatic milking system (AMS). Studies have shown that transition to AMS affects the udder health of cows adversely, recognized primarily as elevated somatic cell counts. There are several reasons for this, for example the greater variation in milking frequency seen in AMS. On one hand, short milking intervals may lead to bad teat condition of the cows due to the stress the milking procedure exposes the teats to. Too long milking intervals, on the other hand, seem to predispose for milk leakage, which is, in turn, a risk factor for the development of mastitis.

Strategisk marknadsföring av produkter av rapsolja :

The background to this study is to find alternative ways of size rationalization. My vision is to take the basic conditions and make the best and most profitable of them. I have chosen press of rape oil because it?s interesting and the investment to get started is relative small. The opportunity to use outmoded and unrational buildings which often are found at many farms to something that gives money instead of costs money is also an argument.

Omvårdnadsrutiner för katt med astma

Feline asthma is a condition very similar to the respiratory disease affecting humans. It is causing, among other things, a constriction of the bronchial airways, an increase of mucus production and damage to, or erosion of, the epithelial membrane. The symptoms occur intermittently and do, in most cases, evolve during a long period of time. The aim of this essay was to investigate whether there are any nursing routines for feline patients with asthma in animal clinics and animal hospitals in Sweden, and if so, to compare similarities and differences. A literary study of research material also led to a suggestion of how to form a nursing routine for this type of patient.

Theyboth illustrate my uncertainty concerning the unpredictability of conversations with distressed orstressed parents. I can prepare the environment, by cleaning and making it look nice before meetingwith the parents.

Genus i barnböcker

The purpose of this essay is to examine and compare how womanliness and manliness reveal themselves in different children?s books, mainly focusing on the concept of gender, in both text and images aspects. The questions I have chosen to interrogate are the following:How is the male and female role represented in children's books from a gender perspective, in both images and texts? What gender is generally the main character in children's books? What clothes are the characters wearing in children's books? What kind of occupations do the characters practice in children's books? What kind of qualities or attributes do the characters possess in children's books?When it comes to the selection of the method, I have chosen the use a qualitative method, where I use both a text and image analysis. The essay is based on Hirdman's and Hardning's gender theories and alsow on Nikolajeva's theorie about male and female.

Jämförelse mellan två tandvårdskliniker avseende progression och behandling av approximala kariesskador ? en journalstudie

Preventive measurements as well as clinical caries diagnostics are vital to retain a good dental health in the population. In order for optimal caries diagnostics radiographs are used. There is a great intra- and intervariation regarding cariesprogression. A large number of tools for cariesprevention at home or in the clinic are today used. The aim of this journal study was to compare the progression of carieslesions in the approximal area, diagnosed on radiographs, and preventive measures used to reduce cariesprogression between two examine dates on two dental clinics.
