Sudoku solvers are a widely researched topic among mathematicians and computer scientists. This report investigates the differences in execution time and time complexity between backtracking and human strategies for classes with 17-21 clues. Backtracking is compared to our implementation of human strategies with test data that contains 99 Sudoku puzzles for each class. The study shows that the execution time and time complexity is improved for human strategies compared to backtracking for each class. The conclusion shows that it is always favorable to implement the human strategies investigated in the report. .

In this study we have examined in which way the horse is used in Equine Assisted Therapy, and what effects the treatment staff experience and describes that the interaction with horses has on girls who self-harms. Our Empirical data was collected through qualitative methods such as interviews, participant observation and informal interviews with a total of six different informants, from five different activities with Equine Assisted Therapy for girls who self-harms. In the analysis we have assumed symbolic interactionism, a theory focusing on the human as a social being, where the self-image alters in the social interaction with other human beings. We interwove this theory with the Biophilia hypothesis, an explanatory model concerning human?s relationship to animals and nature.The conclusions we have found in the results are:Equine Assisted Therapy is a complementary treatment comprises both horseback riding and exercises which is not based on the horsebackEquine Assisted Therapy almost always involves three parts, the therapist, the client and the horse.

The purpose with this essay is to examine the role of landscape photography as a portrayer of nature. The study contains interviews with eight landscape photographers, to find out how they look at tendencies and changes in photography. The essay focuses on the discussion of authenticity and realism in landscape photography. Due to the requirement of nature as something natural and authentic, the landscape photography stands in a special position when it comes to matters of manipulation and influence. On the basis of certain analysis themes, the landscape photographers debate questions such as where landscape photography stands today, and how the future looks for the genre..

When stormwater occurs near human activity the water gets polluted. The purity and composition vary widely depending on the types of activities in the area, the type of surface the water comes in contact with, precipitation and many more parameters. It has long been known that stormwater quality can affect both human health and the environment as stormwater is a major contributor to pollution of receiving waters.A human activity that has an impact on the environment in several different ways is traffic and stormwater is no exception. Airborne gases that react with precipitation, oil leaks and fuel systems that drops down on the ground, metals from brake linings and rubber particles from tire wear are some of the aspects you have to take into account when categorizing the relationship between traffic and polluted stormwater.In this project, stormwater samples from a parking lot in Halmstad, Sweden were collected and analyzed with an atomic spectrophotometer. The presence and relationship between copper, cadmium and zinc with different rainfall parameters have been studied.

Assessment of impacts on nature and reindeer husbandry by the considered mountain road between Borgafjäll and Saxnäs- Swedish National Road and Transport Research Institutes method for assessment of damage to heritage assetsThere are plans regarding the building of a new road from Borgafjäll/Båtas to Saxnäs, and two road alternatives have been presented. The road has been localized to an area which is protected as a nature reserve and listed as a Nature 2000 area. This report aims to determine the effects on the Nature 2000 area and reindeer husbandry, and to be a source of knowledge for future environmental impact assessment in that project. In order to assess the impact on nature values and reindeer husbandry a method from the Swedish National Road and Transport Research Institute (VTI) has been used. A literature review has been made to prescribe the effects and consequences.

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..

Abstract   The actions of Sweden during the second world war has been richly discussed over the years. Sweden declared itself neutral in the war between the great powers but did not manage to maintain its neutrality. The nature of neutrality has often been discussed; whether it is of a idealistic or more pragmatic nature. Realism, a theory of international relations, would argue that it is of a more pragmatic nature, hence these two are in opposition. Realism also takes credit in claiming to explain how and why a state chooses to act in a situation. The aim of this essay was to, by examining specific decisions made by the swedish government during the Second World War, come to a conclusion whether or not Sweden?s proclaimed neutrality was of idealistic or pragmatic nature, and thereby possibly coming to a conclusion about neutrality in large.It was also to examine the worth of realism as an explanatory theory by applying it to this specific case; to examine its validity.The study was conducted using a qualitative method; presenting empiric facts and then by using a decision model interpreting the actions and results from a realist perspective. The study concludes that realism has explanatory power, although not a complete one.

Biodiversity is essential for human well-being and it is defined as the genetic variation within species and the variety of species and ecosystems. Biodiversity provides several ecosystem services which are necessary for human beings but there are different threats towards the biodiversity. The biodiversity linked to the forest in Sweden are threatened, about 50 % of the red-listed species in Sweden are associated with forests. This is linked to the commercial exploitation of the boreal forest in Sweden which started 200 years ago. The forestry the last 50 years, with clear-cuts, have contributed to a fragmented forest landscape.

The Swedish political organization is subject for the investigation of this thesis, with regard to the realization of universal human rights. There is a discrepancy between the Swedish state's international undertakings in legally binding treaties and theactualization of human rights by local authorities. The local authorities are ruled by a complex function of both national and local government. Of interest here, is the effect that these, and other organizational aspects, between the national and the local, have for the realization of human rights in local authorities. Also, the discrepancy between the national and the local is attempted to be understood.

Through a quantitative examination, 26 pedagogies in the pre-school activity answered a few questions in an enquiry about outdoor education. The purpose with this examination was to find out what pedagogies think and apprehend about outdoor education, and also if the "education plan" is in their minds during outdoor activities and if they see them self´s as competent in nature studies. They have also answered questions whether they think that they have good outdoor environment that stimulates children´s development and learning and if there´s any forest that they visit on regular basis.The pedagogies think that during time spent outdoor, it´s the motor skills that are best developed. All of the pedagogies mentioned above think that they need to get more educated in nature studies and also that pedagogies attitude towards time spent outdoors affect the children. They do not think about the goals and intentions of the "educations plan" all the time.

The examination of the adequate nature conservation methods in a natural reserve, to conserve a specific species and / or increase biological diversity is the subject of this study. This work is based on four species, that can be found during the Spring season, liverleaf, wood anemone, brimstone and woodpecker. The incidence and availability is studied and closely observed for these species in twenty forests, i.e. ten forests which are nature reserves and ten forests with the similar characteristics as the nature reserves habitat, but are not nature reserves in Gnesta mucipality, Södermanland. Measurements of the tree crown and the diameter of the tree trunks where noted to study how these factors could affect the outcome of the abundance and incidence of the four species.

Around 85 percent of the total population in Sweden today lives in an urban environment. This means that the nature within the urban areas has come to play an important role for the human well being. At the broader picture, the nature within urban areas is profitable in many ways. It is therefore important for the municipalities around in Sweden to work for sustainability within the urban areas. Linköping adopted an environmental policy, in year 2001, from the delegate of the municipality.

The purpose of this study is to examine which security approach dominates Sweden?s strategy for combating human trafficking. The two approaches covered in this essay are the state- centred perspective, and the individual-centred perspective. These approaches are being used because those two approaches are on each end of the security spectrum, and it is important to discover from what approach Sweden is working. This is important because it might help us to get a bigger understanding on why certain policies are being made.
