Even minor health effects may be important for the whole population. Stroke patients require the largest number of days spent in hospitals and nursing homes than any other medical condition group. Risk factors for stroke include smoking, high alcohol intake, physical inactivity, hypertension, hypercholesterolemia, high waist-hip ratio and diabetes.

The interest in harvesting wood fuel in conflict stands has grown in recent years as a consequence of the increased demand for biofuel. Conflict stands are young forests that have not been cleaned and have a large number of stems ha-1with a great height and diameter distribution. This means that traditional field measurements in conflict stands are difficult and very time consuming. Therefore, the forestry sector is in need of new, more efficient inventory methods. In this study, the Lidar data from Lantmäteriet?s (the Swedish mapping, cadastral and land registration authorities) new national height model was used in combination with plots from the Swedish national forest inventory from 2009 to create functions for; height, volume, diameter and number of stems.

In light of the European Union`s 2012 theme year: Active aging and solidarity between generations I wished to gain an understanding of weather elderly immigrant are provided with equal possibilities and access to local community information as the majority population and their participation in activities arranged for senior citizens in the municipality where they live. I have done this by meeting with those who work in this capacity. I also chose to meet with representatives for immigrant organizations in the local community to enquire of their work with senior citizens within their own ethnic group. This is a qualitative study on a phenomenological ground based on nine interviews and four observations. I have had two theories to help me analyze my empirical material.

In relation with structure transformation in farm companies with bigger animal population and pressure at the milk price, the farmers in both countries have to invest more money in the company to endure. This had conduct what more owners had seen grown requirements to invest in bigger population barns. The investment is necessary to retain stability in the economy for the companies, at that time when the profitability for small production barns decrease. This essay carries out through a case, there the activities main part are milk production. The present operation consists of 82 milk cows in long stall with a yield on 10 500 kg ECM. The idea is that the company should increase the activity to 180 cows.

The Northern Raccoon (Procyon lotor) belongs to the Carnivore-family and is a species endemic to North America. Every year hundreds of orphaned raccoon cubs are admitted into the Wildlife Rehabilitation Center of Minnesota (WRCM), a non-profit organization where all injured or orphaned wild animals are admitted and receive quality health care with the goal of being released out into the wild. The WRCM routinely vaccinate all of the admitted raccoon cubs with a killed feline panleucopenia vaccine, but despite this there are outbreaks of parvovirus infection every year where up to 50% of the admitted cubs have been euthanized or died. The objective of this study was to determine whether vaccinating the admitted raccoon kits has any significant protective effect to developing clinical parvoviral disease. A single-blinded cohort study was designed with two parallel, independent groups. One group was given a dose of killed feline parvovirus vaccine at admission, and the other group was not given any vaccination at all. Assignment to the vaccinated or unvaccinated group was on a per-litter basis and done randomly by drawing lots out of a box.

The problem of separating a non-rectangular foreground image from a background image is a classical problem in image processing and analysis, known as matting or keying. A common example is a film frame where an actor is extracted from the background to later be placed on a different background. Compositing of these objects against a new background is one of the most common operations in the creation of visual effects. When the original background is of non-constant color the matting becomes an under determined problem, for which a unique solution cannot be found. This thesis describes a framework for computing mattes from images with backgrounds of non-constant color, using Bayesian statistics.

The bark from prehistory ? an osteological analysis on dog bones from the Stone Age settlements of Hemmor and Gullrum at Gotland and a theoretic study of the secular and sacred roles of the dog during the Neolithic.Dog bones from two Pitted Ware Culture (around 2500 BC) settlements, Hemmor in När parish and Gullrum in Näs parish/Havdhem parish, at southern Gotland, Sweden are analyzed. The analysis contains a study of age, withers height and size estimation as well as skeletal changes and pathologies. The attempt of the analysis is to highlight the secular and sacred role of the dog during the Neolithic at Gotland. The dog bones were collected during excavations in the years 1890 and 1903 and were found across the entire surfaces of the settlements.Although there were no specific dog breeds during the Stone Age, the dogs at Hemmor and Gullrum show a wide range of size (withers height spans from 39,74 cm to 56,47 cm) and may therefore have been used for different purposes depending on their size.

It is in society's interest that news is conveyed in a correct and memorable manner. News contributes to general knowledge and increases awareness of other people's life situations. Because of news the population is able to follow and be a part of the political debate. Therefore, it is important that one remembers what one has seen, both in long and in short term, i.e. memorability is a critical aspect when it comes to news.The aim of this work was to study the news form a memorability perspective, that is, how long one remembers the news after watching them.

In this report an MCNP (Monte Carlo N-Particle) model is described for the reactor vessel at Ringhals 2. The model is validated against the specific activity in neutron dosimeters, extracted in 1977, 1984 and 1994. The validation showed that the calculations of the model are within the requirements of a maximum of 20 percent uncertainty for every neutron dosimeter except one, extracted after the first cycle. The uncertainty of this cycle was mostly due to the operation data rather than to the MCNP model.The model has been used to investigate various questions concerning radiation damage. The reliability of the traditional measure of radiation damage, fast neutron flux (En > 1MeV) has been evaluated.  This has been done by taking the ratio for this and another measure of radiation damage, DPA (Displacement Per Atom), for various positions and layers.

Aim and questionsThe purpose for this study was to investigate how marks and mark settings are formed in physical training at some compulsory schools. We also wanted to see how the criteria for marks are formed. These were the main questions during this study.? How do the students find the evaluation and the making in physical training?? Are there differences between different student groups when it comes to their experience around estimation and marking in physical training? (gender, marks, schools etc.)? How do the teachers motivate their marking in physical training?? Are there any differences between the criteria for marking between different schools?MethodThe study was carried out during the spring 2005 at eight schools in a municipality in the middle of Sweden. The study involved 339 students opinion polls and 12 teacher opinion polls.

This essay deals with the paradox of why the immigrants in Sweden, despite their considerable size of 12 % of the population and common interest and living opportunities, haven?t mobilized politically in any significant way. The aim with this essay is to reach a theoretical understanding of why this paradox exist. By the use of a critical case and a theoretical model, based on theories of collective action, the conclusion of this essay is that, despite the fact that the immigrants have a common interest and an organizational structure, the immigrants in Sweden has not mobilized politically in any significant way. The main reason for this is that they have a weak common identity and they don?t have the structural opportunities to act..

India is the country with the highest prevalence of rabies in the world, with about 20?000 human deaths occurring every year. The country also has a heavy burden of free roaming dogs, mainly because of the high amount of edible waste in the streets, which are the main hosts for the disease. Therefore to truly extinguish rabies, the main focus should be on the dogs, both stray dogs and owned. One method is to vaccinate all dogs against rabies.

Inledning: Syftet med denna studie är att, utifrån ett insamlat material vid S:t Lukas mottagningar i Stockholmsområdet, undersöka symptomförändring från start till avslutning i psykodynamiskt inriktade psykoterapier.Frågeställningar: Den övergripande frågeställningen är om patienter och terapeuter bedömer att terapierna haft någon effekt och i så fall vilken. Vidare om bakgrundsfaktorer och självbild påverkat symptombelastningen.Metod: Studien har genomförts med hjälp av självskattningsformulär som fyllts i före och efter behandling. Patienterna har fyllt i Symptom Checklist (SCL-90) och terapeuterna ett frågeformulär där de skattat patienternas besvär. Efter inomgruppsjämförelser har jämförelser gjorts med ett normerings-material.Resultat: Det sker en signifikant symptomlindring under terapierna. Störst är förändringen när det gäller depression, ångest och interpersonell sensitivitet samt i det sammantagna genomsnittsvärdet.

Most descriptions of stereotypic behaviours have in common that these repetitive behaviours only has been observed in captive animals and therefore it has been proposed that stereotypies exist because we house animals in environments that are sub-optimal to them. Some scientists claim that performance of stereotypies in itself decreases the animal's welfare due to costs in time, energy and health and a poorer quality of life. Other scientists assert that individuals performing stereotypies may have a better welfare compared to the rest of the animals in the same environment, since these individuals have developed strategies to cope with stress. Studies have estimated the prevalence of abnormal behaviours in horses to 18-30 % of the population. Several studies on cribbing have revealed a prevalence of 4-5 %, although some results indicate that more than 10 % of the horse population performs this stereotypy.

From 1710 to 1713 the plague raged through the Swedish province of Scania. Other studies have been made on how the disease affected the society during the epidemic. This study tries to focus on the recovery afterwards. How did the population and the farmsteads recover after the plague? Statistics from parish registers and cameral records show interesting patterns in the demography, and that the recovery was far from complete 1720.
