Biodiversity is under threat in Sweden and many species are on the brink of extinction. This is mainly due to the large-scale drainage projects during the 19th and 20th century and the increasingly intensive land use in agriculture and forestry. The intensive land use with sharply defined boundaries between the production units has in many cases led to either overgrazing or overgrowing. As a result many species have been pushed back to "leftover" habitats like shooting ranges, power line corridors, roadsides, dumps, embankments and other similar areas. Therefore the question has been raised, wether or not it is needed to re-introduce large herbivores into the wild in order to maintain the biodiversity that is related to the extensive land use.This study has been conducted as a literature review and will focus on the European bison?s (Bison bonasus) impact on other species and biodiversity; conditions for reintroducing large herbivores in Sweden are also discussed.Free roaming populations of large herbivores have a positive impact on plants, insects and many other groups of organisms.

Two different methods for measuring biogas production were used, gas meter and gasbags. The gas meters were electronic and counted each time a certain gasvolume passed through them. The gasbags collected the gas that hade passed through the gas meter until a manual measuring could be done. The two different methods gave the same result for a volume at three liters but for a volume around 0,2 liters they did not. Accuracy and precision for the gasbags was more exact than for the gas meters even if the method was difficult with a lot of different elements that could affect the result.

Today's global market means that raw materials are sought and bought from all over the world. This creates an higher demand for a well-functioning supply chain. In our thesis we have studied a large paper mill in northen Sweden which experiences issues with flow of raw material. Our aim has hence been to examine which aspects affect the flow of raw materials to the mill, and how these can be adressed using an IT-system. The question we sought to answer was; What factors are important to consider and how do these affect the ability of an IT-system which will support the flow of raw material at the paper mill? We have found that the problems are strongly connected to the low amount of information sharing between the mill and the suppliers.

Abstract The goal of the study was to conduct an in-depth investigation of how conflicts are resolved in schools, from a pupil- and a teacher perspective. Our intention was to view and compare pupils and teachers different opinions in the school environment. A major focus was put on different ways teacher handle conflicts and how they try to prevent them. The material was acquired by interviews with both teachers and pupils. The study is based on Jean Piagets and Lev Vygotskijs visions about the cognitive developmental stage for children. The result of the study shows the teachers need to be attentive and also that the pupils generally do not notice when the teacher works to prevent conflicts.

The Swedish building and property management sector are responsible for about 30 % of the total energy use. In order to take environmental consideration, different environmental assessment tools and standards are used. Miljo?byggnad, Svanen, FEBY12 and PHI are some of these. There has been increased interest to certify buildings and therefore it is of interest to evaluate the assessment of the energy field to see if relevant energy aspects are assessed.

Andelen  äldre  i Sverige  ökar. Hos normalhörande  äldre människor  sker  det  en  förändring  i taluppfattningen som är en del av det naturliga åldrandet. Syftet med denna studie är att belysa det  biologiska  åldrandets  påverkan  på  den  åldrande  individens  taluppfattningsförmåga.  En systematisk  litteraturstudie  har  använts  som  metod.  Resultatet  från  övervägande  delen  av använda  artiklar  i  denna  studie  visar  att  normalhörande  äldre  har  sämre  taluppfattning  än normalhörande  yngre.  Den  försämrade  taluppfattningen  är  enligt  artiklarna  ett  resultat  av förändringar i det centrala hörselsystemet. Artiklarna pekar på att dessa förändringar beror på förändrad  lateralisering,  förlångsammad  kodning  av  talsignalen, minskad  nervaktivitet  eller förtvinade nerver i hörselkortex..

This dissertation examines how creativity can be of benefit for the school. It discusses if there is a need or demand for it and how the present situation is in Swedish schools. Defining creativity accurately is difficult but it is relevant to look at the environments that use creativity. There is a vast amount of literature that uses creativity and it varies to some extent. Creativity originates from meetings and combinations, both within and outside of the individual.

The case method is a relatively new pedagogical method in Sweden that is based on students exercising their skills in the analysis of complex situations and problems that are based in reality and that help students to see a broader perspective and context.The purpose of this study has been to investigate, through interviews with students and teachers, the advantages and disadvantages of the case method in teaching geography.The results of the study show that both teachers and students share almost the same opinion. The conclusion is that the case method is a didactic method that is well suited for teaching geography, as it is based on reality and develops the students? ability to analyze, argue and find solutions in several areas within the subject of geography. If a student is strong in these skill areas they can really benefit from the application of the case method in the teaching of geography, but for students who are weaker in these skills, the case method can be a disadvantage.

I en allt mer föränderlig omgivning utgör innovation ett nödvändigt redskap. Syftet med denna studie är att undersöka om arbetskrav och arbetskontroll samt interaktionen dem emellan har en betydelse för ettgruppklimat som främjar innovation. Arbetskrav och arbetskontroll definieras i denna studie utifrån Karaseks teori om krav- och kontrollmodellen. Innovation definieras utifrån Wests teori om de fyra gruppklimatfaktorerna som främjar innovation. Resultatet baseras på en enkätundersökning med 83 respondenter fördelade på 20 arbetsgrupper inom den privata sektorn.

This study has the purpose of looking at the current and future position of record labels from a context involving the technological developments, while the opportunities for the artists are changing. As the actors inside them music industry find themselves in an ever changing climate where traditional supply chains are threatened by new technology, the record labels need to change the way they work in order to maintain their existence in the music industry. The study has been conducted by interviewing a number of people involved in the music industry, by using a qualitative method approach. The conclusion of the study shows that the traditional way of doing business by treating music as a product that makes revenue is gone. Instead the labels have to take on new roles formerly run by third parties in order to survive and be profitable, especially since artists can now in control of activities that used to be controlled by the record label..

In Sweden the social assistance from a historical perspective, has been a part of the social legislation, since the 18th century. In that time called poor relief. Through the centuries this has established the social assistance we have today. With focus on the child, we have attempted to illustrate how the social workers consider the child perspective when they are dealing with the social assistance. We wanted to get a view of how the social worker reasons about needs the children have and how they can see that the benefit has been provided for.

The aim of this literature review is to give an overview of the differences between pure- and crossbreeding systems. Crossbreeding is a mating system with individuals of different lines or breeds. It is one of several breeding strategies in dairy production used to increase the economic profit. The use of crossbreeding increases due to changes in the dairy market and an increase of inbreeding among purebred Holstein. The main benefit of crossbreeding is heterosis, which is the improvement in genetic level in a hybrid offspring above the average of the parent breeds.

"Landscapes for Spontaneous Sport" The main aim with this degree thesis is to show how planning and design of urban space can promote spontaneous sport. Public health and urban life would benefit from re-introducing the sport and physical activity in the townscape. The study can be seen as an "inspiration book" that focuses on the connection between sports and landscape architecture. The starting-point for the discussion is the fact that the spontaneous sport is on the decline and the main general question is how this negative trend could be broken. In particular the study asks how landscape architecture could promote and increase spontaneous sport. Good examples of places for spontaneous sports of different kinds are given, both from Sweden and from other countries, which have inspired a case study where I propose a redesign of a centrally located, but hardly used park in Skäggetorp, a suburb of the town of Linköping. .

The craft of planners are planning for a better future. Knowledge about climate change, environment, health and availability effects the trend towards less car dependent societies in favour of public transport and active transport like walking and biking. This study takes place in Västerbotten, one of Sweden?s most north provinces with a population of 260 000 inhabitants. It is a sparsely populated area with two dominant cities, the other municipalities are largely unpopulated.

SMTP, the current protocol for sending electronic mail (e-mail) over the Internet, has for many years suffered from several problems and limitations. When it was designed, well over twenty years ago, the requirements for e-mail were very different from those of today. A message was a text message in English, and both user and machine were explicitly named in the address. The protocol was not designed to transfer other types of messages, and no mechanism was included to verify the identity of the sender.In order to solve these shortcomings, a new e-mail protocol needs to be defined. This report specifies a basis for what such a protocol may look like.
