Warmer climate is a driving factor to species expansion northwards. Expansion to new areas can result in escape from natural enemies, resulting in reduced levels of mortality and thereby potentially increasing the rate of expansion. The most important parasitoid species attacking butterfly larvae belong to the families Tachinidae, Ichneumonidae and Braconidae. The aim of this thesis was to investigate parasitism and difference between populations in established area and newly colonized area for the European map butterfly, Araschnia levana, in order to examine if the butterfly has escaped from some natural enemies. In 1982 the first European map butterfly was observed in Sweden and has now established up to middle Småland.

In this trial we used QualispermTM as an objective method of measuring stallion semen. Samples of semen were analyzed before and after centrifugation. Motility and concentration were statistically analyzed. During the trial all the objective mesaurments were compared to a subjective method. The advantages of QualispermTM compared to older CASA- systems is it´s ability of measuring a greater amount of spermatozoa while it also grades them into different subpopulations. These subpopulations have different qualities that decides their capacity of fertilization. The results showed that this objective method might be used practically. Although, there are still some disadvantages, such as high costs and the necessarity of accurat training of the handler. If it´s possible to prove further relevant results that also are statistically correct, this could prove the usefulness of QualispermTM as an objective measurment method in the daily work at gestuts and stallion stations, thus giving the staff a reliable instrument in assisting the work for an improved horse breeding in Sweden, improving both in quality and economically..

This investigation is a pilot survey whose main purpose is to investigate with work evaluation and attitude analysis whether the orthopedists and surgeons work can be equaled, why the wages differences exists between women and men, and also which preventive measures the organization can use to even out the wages differences between the genders. In relation with the investigation I have applied the reflexive way of thinking to establish which difficulties come up in the work of gender-equality.The result?s from work evaluation displays that the works are equivalent but the salaries are not, which can depend on value discrimination,gender discrimination and the organization theory.Wages differences between women and men depend on, according to the informers, partly by historical explanation and partly by the old directors who was allowed to retain regular salary when theypost transformed. The common point of view is that men have a larger work experience and therefore a higher salary.The managements attitude towards gender-equality issues is of absolute importance in order to achieve and bring a change within the organization.The measure positive special treatment is proposed to be used as an improving method to achieve (gender)equality between the posts and to even out the wages difference between the sexes.To establish whether or not gender discrimination exist in the investigated organization there needs to be done a whole lot supplementary studies like a complete wage (salary) mapping which includes all supplements and more interviews among the organizations all occupation groups..

Tourism is often being viewed as one of the worlds largest sectors and a great contribution to growth and development. There is a large motivation amongst developing countries to promote themselves as a tourist destination, since they expect the tourism to generate economic growth. The government of Thailand has been promoting tourism since 1960, and the number of foreign visitors has increased from 100 000 back then to 13.5 million in 2006. The purpose of this paper was to investigate weather the increasing tourism industry in Thailand has pulled resources away from other sectors of the economy towards the tourism sector, and in that way harming Thailand?s international competitiveness and causing deindustrialization.

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.

Voltage sag indices are a way of quantifying the performance of the power supply, as far as voltage sags are concerned. Indices can be defined for individual events, for individual sites, and for a whole system. A standard method for single-event methods is part of IEC standard 61000-4-30.This thesis emphasizes the importance of voltage sag indices and different methods for calculating three-phase voltage sag characteristics. Three-phase events measured in a medium network voltage over period of one month were analyzed, results examined and statistically evaluated. An algorithm for calculating voltage sag characteristics and indices was created in Matlab.

The aim of this Masters thesis is to analyse school librarians and teachers perspective of childrens reading and reading progress, the impact of informational texts on childrens reading and how school librarians and teachers work/teach to improve their students understanding of informational texts. We also intend to study what consequences school librarians and teachers believe that childrens reduced understanding of informational texts can have in the long run and how this could be improved. The theories applied encompass different literature-pedagogical strategies, theories about reading purpose and direction of the reading process together with a theory that shows the school librarys function in the education. The empirical material has been collected through interviews with one school librarian and one teacher at three different schools. The material has then been analysed and interpreted from theories and earlier research.

The use of artificial insemination (A.I.) as an alternative to normal mating in dog breeding in Sweden are controlled by regulations from the Swedish Board of Agriculture and by ethical rules assigned by the Swedish Kennel Club. Only veterinarians, who have a specific certificate and are specially trained and educated, are allowed to perform inseminations in dogs. Each artificial insemination must be documented and reported to the Swedish Kennel Club (SKK) which, on the behalf of the Swedish Board of Agriculture, yearly presents statistics concerning the use of A.I. in Sweden. The objective of this study was to illustrate the use of artificial insemination in dog breeding in Sweden for the last decade, using the yearly reports from the Kennel Club during the period of 1995 to 2004.

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..

This thesis is an investigation of Iranian immigrants and their use of libraries in Sweden. It isbased on a combination of a qualitative and a·quantitative method.Using a qualitative method, I give an outline of the history of lran from ancient times up to the present, as well as the different ethnological groups in Iran and their cultures. The main objective of this part is to clarify the contrasts between Iranian and Swedish cultural, social, linguistic and family structures, and also the characteristics of the crisis that most immigrants go through on their arrival in the new country. The qualitative method also involves structured telephone interviews with eight highly educated Iranians.This method was supplemented by a quantitative study through questionnaires of the attitudes· of lranian immigrants to libraries and reading. Iranians in Sweden turned out to be frequent Iibrary users.

The biogas plant Kungsängens gård, owned by Uppsala Vatten och Avfall AB, produces biogas and biomanure from organic household waste, food processing waste and slaughterhouse waste. In year 2012, 4.4 million Nm3 of biogas were produced from 25 200 tons of waste. Before digestion all substrate is sanitized by pasteurization at 70°C in order to kill pathogens. Another method, integrated thermophilic sanitation (ITS), is of interest in order to decrease the energy demand. The method implies that the substrate is sanitized during ten hours in the digestion chamber, where the temperature is 52°C.

In order to avoid harmful substances ending up at the municipal sewage treatment plants, it is important to purify the wastewater at the source. One such source is the wheel washers available in many tire garages which are used to wash the wheels on our vehicles when we change between summer and winter tires. It is important to wash the wheels before storage, to extend the tires lifetime. The purpose of this study is to find a green innovative solution for reduction of emissions of heavy metals at the source, so that the sludge from the sewage treatment plants can be used as fertilizer. The target is to find a wheel wash method which leads to compliance with the guidelines for car washers, and that also provides a better washing result than with the existing method.
