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.

The purpose of this study is to explain how shame can be experienced by women with the stigmatizing illness of alcoholism. Another aim is to illustrate how this shame can be affected in social interaction with others and by other circumstances. The following questions will be highlighted in this essay: How can shame be experienced by female alcoholics? What can affect shame in interaction with other people, from the view of female alcoholics? What other circumstances can affect the shame, from the view of female alcoholics?This study features interviews with women who have successfully gone through the process of rehabilitation from the illness of alcoholism, have a long going and stable sobriety and arecurrently part of the work force. The study also features interviews with therapists specializing in the field of addiction recovery and have considerable experience in their fieldof working with women suffering from alcoholism.The subject matters shame and stigma form the theoretical/analytical tools for this research.

Background: Poor perineal wound healing and infections after proctectomy surgery, affect a significant proportion of physical and psychological morbidities such as pain, leakage and abscesses. In its lengthening some of these symptoms will lead to extended periods of hospitalization. These kind of postoperative complications are also associated with delays in eventual chemotherapy treatment Aim: To describe the patients experiences of postoperative wound infection as well as communication and self-care support from the nurse specialist after proctectomy due to rectal cancer. Method: A qualitative content analysis was carried out from interviews. Results: Four main categories emerged; ?Coping with postoperative complications?, ?be independent?, ?feel safe?, and ?accept the situation?.

That animals should be able to express their natural behaviours, even in captivity, has become a more important issue lately. Nowadays Zoos work much more with educating people and helping conservation projects for endangered species. This is two important reasons for making the environment as natural as possible for zoo animals. Both in captivity and in the wild capuchin monkeys have been seen to use tools such as stones and sticks to get food and are therefore seen as a natural and important behaviour for them. This study was carried out to evaluate a specific sort of environmental enrichment where a group of three capuchins had to use sticks to get different kinds of food out of bottles.

In the school subject of the natural sciences it is imperative that the students are given opportunities to ?talk science?, since the dialogues that occur in the classroom have a significant importance for the students? abilities to engage in meaning-making in their learning process. Hence, the student and teacher interaction in the classroom and the feedback given there play a significant role in the students? learning process. The aim of this study is to contribute to the development of formative assessment tools that can mediate the students? meaning-making in natural sciences subjects in upper-secondary school.

Many tropical rain forests has been lost or degraded as a result of human activities and environmental factors. Since the level of biodiversity is high in the tropics, maintaining these areas is of great importance. Forests like these are often assumed to benefit from forest restoration and rehabilitation. The INIKEA project area in Eastern Sabah, Malaysian Borneo, aims to improve biodiversity and/or species richness in the degraded forest through enrichment planting with indigenous species. The objective of this thesis was to evaluate how different treatments (liberation, gap-cluster planting and line planting) affect the biodiversity of natural regeneration in different forest types in the Rain forest Restoration Experiment, located in the INIKEA project area.

This study is about how students 'performance in school is influenced by parents' educational background. The study has been performed by cooperation with two schools in Stockholm. One class in each school has participated and the students have amongst other questions answered regarding their grades in natural science subjects. To examine whether parents 'educational background affect students' performance, a quantitative survey in the form of poll has been conducted. Even a literature review was conducted in this area to get a clearer picture of how parents' educational background affects the performance of students.This study shows that students who have academic parents perform better than students who have not got academically educated parents.

I takt med att Försvarsmakten ökar sitt internationella engagemang ökar också riskerna för att svensk personal ska bli isolerad, tillfångatagen eller kidnappad. Syftet med den här uppsatsen är att undersöka om svensk undsättningsförmåga är tillräcklig för de insatser som Försvarsmakten genomför internationellt.Det kan konstateras att flera faktorer bidrar till ett behov av en undsättningsförmåga. Försvarsmakten har en moralisk skyldighet mot sin personal att göra allt för att se till att de kommer hem ifall något skulle hända dem. Försvarsmakten har heller inte råd att få personal kidnappad då det genom media och hemmaopinion kan ge ett högt tryck på politiker vilket i sin tur kan leda till att Försvarsmakten tvingas dra sig ur en insats. Förvarsmakten måste även kunna ansvara för sig själv och inte förlita sig på att en annan nation ska lösa problemet när situationen inte kan hanteras.

Introduction: Sexual abuse is more common than statistics show; the number of unrecorded cases is high. Sexual abuse is hard to deal with, it is associated with taboo and shame and at the same time it is a trauma to the one who has been abused which will effect the rest of that persons life. Aim: The aim of this literature review is to describe men and women?s experiences of being sexually abused. Method: A literature review, inspired by Friberg (2006), was conducted.

A passive house in Norra Djurgårdsstaden drawn by Tengbom Arkitekter is going to be built. A shaft for airing is needed for a few apartments in the house.The airing shaft is designed for a few two room apartments in the house, which are not able to achieve satisfactory airing, as their outer walls are facing a single direction. The other apartments on the same floor are corner apartments. These apartments do not have the same difficulty with airing since they have their outer walls in different directions, with different pressures at the facades. The airflow in the airing shaft is supposed to be driven only by natural forces, by the sun. The purpose of natural driven forces is to achieve low energy consumption for the house.In this thesis, a design of the shaft for airing has been developed.Initially an open shaft for all apartments was analyzed.

By tradition horses are weaned at an age of 5-6 months. This study illuminates weaned foals misdirected suckling behaviour, which means that they try to suckle another foal. Since no information about this issue is presented, we decided to perform a behaviour study on weaned foals. The misdirected suckling behaviour was studied on a group with 7 foals, with both fillies and colts. In the group the weaning age varied between 147 days and 215 days, and the first time we observed them, they had been separated from the mares for 12 days.

I uppsatsen jämförs William Paleys Natural Theology : or, evidence of the Existence and Attributes of the Deity, collected from the appearances of nature från 1802 med Michale J. Behes Darwin's black box : The biochemical challenge to evolution från 1996. Jämförelsen kontextualiseras med en skiss över evolutionsteorimotståndets historia under den mellanliggande perioden, som tillsammans med själva den vetenskapliga utvecklingen, antas förklara de skillnader i tilltal och val av argument som föreligger mellan de två verken. I fråga om grundläggande budskap, idéstruktur, syfte och religiositet befinns de två verken ligga varandra betydligt  närmare än vad som initialt kan tyckas vara fallet..

In Sweden we are spared from large natural disasters. However, in January 2005 part of Sweden was struck by a hurricane. It did not only leave a decimated landscape in its wake. It also left its mark on many people who lived in the south of Sweden. In this paper the reader will be presented six qualitative interviews that build on forestowners' experiences during and in the aftermath of the Storm of January 2005.

The purpose of this report is to investigate the possibilities with drain water heat recovery (DWHR) in residential buildings. Information and relevant theory has been collected and summarized in this report. Calculations have been done for given scenarios to evaluate profits. DWHR heat exchangers use simple technology and have long life-time. The heat exchanger is connected to outgoing drainage pipe and incoming cold-water supply so countercurrent flow is accomplished.

Through interviews with children of ages 4-5 years old and by observing children children at play at three preschools with different types of outdoor surroundings, I have investigated if the preschools outdoor surroundings have any influences on the children´ choice of play. The hypothesis was that natural surroundings can entice children´s interest in nature being in it and play. I have also investigated if the children know why it is important to be outdoors and if they know it has a positive influence on their health.The result of my investigation is that the children play about the same games at the three different preschool gardens, but at the preschool with more natural surroundings, the children have more contact with plants and animals, and could learn of the different phenomena of nature by the preschool teacher answering their questions. Most of the children in the interviews know it´s useful to be outdoors and be on the move and get fresh air, but many of them thought it was most important to play. By being outdoors the children get exercise, fresh air, play and at the same time they establish an understanding of the nature and a healthier life..
