The purpose of this study was to compare naturally regenerated Scots pine (Pinus sylvestris (L.)) against seeded Scots pine in terms of benefits and differences. An inventory was performed at a number of different sites, 4 ? 6 years after soil scarification and data on the number of new established plants, their height growth as well as ground-line diameter was collected. Information about site conditions such as altitude, quarter exposure and frost risk was also collected. A review of previous studies was conducted in addition to the field study.

Polychlorinated biphenyls, PCBs, were used in elastic sealants in buildings during the years1956-1973. Studies of PCB have revealed that it is harmful for humans and animals,especially water-living predators and other top-predators. It is also a persistent organicpollutant and remains in the environment for a very long time. To reduce the levels of PCB inthe environment, it has to be removed from the buildings. According to Swedish law, theproperty holder has to decontaminate sealants with a PCB level of 500 mg/kg or above.

This report is a case study of ?citizen forums? in the municipality of Uppsala. These forums are arranged to make people participate more in local politics. The aim of this study is to find out if the opinions and the wishes coming from the citizens are later involved in the planning process etc made by the authorities. The aim is also to explain why or why not the opinions from the citizens are of any importance.My empirical data come from interviews that I have made with seven different respondents, both politicians and civil servants.

Den här studien utforskar genom fenomenografins arbetssätt, vad det innebär för rektorer att undervisningen vilar på vetenskaplig grund och beprövad erfarenhet samt hur rektorerna arbetar för detta på sin skola. Skollagen från 2010 har i första paragrafen inskrivet att utbildningen ska vila på vetenskaplig grund och beprövad erfarenhet.  Genom intervjuer har rektorer i gymnasieskolan svarat på vad skollagens nya skrivning innebär för dem. Rektorerna har svarat på vad det innebär för dem att undervisningen på deras skola ska vila på vetenskaplig grund och beprövad erfarenhet och hur de arbetar för att detta ska komma till stånd. En differentierad bild ges av gymnasieskolornas olika förutsättningar att anta denna utmaning. Rektorerna visar på svårigheter med att ge alla elever samma förutsättningar, då bland annat ämne och programtillhörighet ger olika möjligheter.

Lactobacillus reuteri has been used as probiotics in piglet and chicken feedings as well as in different diary products for humans. In this EEF-work I have shown that L. reuteri can be an alternative for treatment of vaginitis in laboratory rats used for breeding. In a breeding stock with 3000 animals some animals had a vaginal infection with ??haemolytic streptococci group G.

Many theories describe failed states as potential threats to international security due to the breeding ground they constitute for transnational terrorism. Ken Menkhaus believes however that transnational terrorists are dependent on a state for their own protection in order to be able to operate.This essay seeks out the relevance in Ken Menkhaus? theory which states that transnational terrorists rather exploit corrupted states than operate in countries where there is a state collapse. His theory will be applied on a case study on post-Libya after Gadhafi?s fall.

This report aims to provide an insight into the particle physics of today, and into the research that goes on within the field. The focus is partly on the recent discovery of the Higgs boson, and partly on how software can be used to simulate processes in particle accelerators. Basic concepts of particle physics and the search for the Higgs boson are discussed, and experimental results, including those from the Large Hadron Collider, are compared with simulations made in MadGraph 5. Furthermore, simple new models of particle physics are created in FeynRules, in order to make simulations based on the models. To support the presentations of these aspects, some of the underlying theory is built from the ground up.

Fruit flies (Tephritidae) are serious pests that cause enormous losses for farmers in many countries. The frequent use of insecticides in controlling fruit flies in fruits and vegetable has not resulted in sustainable management of the pest. Problems associated with this complete reliance on chemical control are many residues of insecticides in crops, health problems for farmers, contamination of water and soil, insecticide resistance development and decrease in natural enemy populations. The implementation of control measures that do not imply an added burden to the environment and/or the farmers is urgent. More knowledge about the ecology of fruit flies is the basis for finding new and better ways to control this pest.

The purpose of this investigation was to find out more about students? spontaneous ideas about properties and transformations of matter. Examples of matter chosen are such which students know about from everyday life and focus is mainly on the questions if students know that all matter has weight and that matter is preserved in transformations.The method used is semi structured qualitative interviews with individual students. Different experiments were carried out together with the students who afterwards were interviewed. However, the students show varying answers and no generalizations can be done.

Hemoglobin is built up from protein and heme groups which give the blood its red colour . Hemoglobin transports oxygen and carbon dioxide between the lungs and other tissues in the body. Normally, a piglet has a hemoglobin value of 130-150 gram per liter blood, and the lower limit before anaemia appears is 80 grams per liter blood. The immune defense is also dependent upon the presence of iron in hemoglobin, since iron participates in different enzyme systems. When the piglet develops anaemia, it becomes pale and thicker around the neck.

This study, based on the socio-cultural theory of the book as a mediating tool, examines how four teachers say they work with the reader ABC-klubben. This is done with a focus on how they reason about choosing the level of readers for the pupils and about what compensation, if any, they make for pupils who read the simpler book and therefore miss the more difficult words and expressions. The result shows that all the teachers say that they take the pupils? motivation for and pleasure in reading as an important ground for the decision as to which reader a pupil should use, and that this decision is taken with a focus on the individual. When it comes to compensation for the pupils who read the simpler book, the teachers do not describe consistently focused work on this, but they describe a similar way of working whereby they nevertheless acquaint these pupils with the more difficult book and the harder words and expressions.

Sweden is a member of the European Union (EU) since 1995. The association results in considerable proportions of the European law, also called EC-law, for Sweden. The legal system has precedence above Swedish law, which forces our national court to take consideration into and interpret the law in the light of EC-law.Sweden doesn?t possess a general legislation of discrimination. An appointed committee investigates the matter and the requirement of a common law, including all discrimination prohibits.
