In the 1970?s it was predicted that in the beginning of the 21st century there would be a timber shortage in Sweden and a large scale introduction of the exotic tree species lodgepole pine started. An introduction of a foreign tree species means a risk of a negative influence on the forests ecosystem. Today, the stands that were established in the 70?s are middle-aged and the effect on the forest floor vegetation can be studied.

Computer programs must give a technical effect that goes beyond"normal physical interaction"to be considered to belong to a technical field. The invention shall be be susceptible of industrial application, which means that it should be possible to reproduce or use in any other industrial way. The reqirement that the invention shall be new means that the technique must not be previously known because of patents, published articles, etc. That an invention shall be a contribution to the state of the art in a technical field means that the invention shall not be obvious to invent for a person skilled in the art. Patents do effect the innovation among the inventers, but in most industries most inventions would be invented independent if there was a patent system or not.

Människors yrkesval och syn på framtida arbetsliv influeras av olika faktorer som i sin tur har formats av evolutionen eller den sociala omgivningen. Människans kognitiva förmågor är ett av elementen som påverkar yrkesvalsprocessen, men är också kanske en bidragande orsak till könssegregeringen på arbetsmarknaden. Hur människor ser sig själva i den framtida yrkesrollen kan också vara en anledning till varför det finns en könsskillnad på arbetsmarknaden. Markus and Nurius (1987) har myntat begreppet ?Possible self?, vilket de definierade som självbilden i framtida situationer.

The invasive species raccoon dog (Nyctereutes procyonoides) is currently under establishment Sweden and it is vital to discover invading individuals to prevent colonization. The use of wildlife cameras to discover dispersing raccoon dogs have been implemented in the north-European raccoon dog management program. In this study, I test the ability of four commercially available scent lures to attract raccoon dogs to camera stations. The study was conducted in the Åland Islands where raccoon dogs are abundant and the results could improve the effectiveness of the camera stations used in the program. I used 12 sites with five camera stations in each and tested the four lures and one control with no lure in each site.

This paper examines Systembolaget and Svenska Spel, two Swedish state-owned enterprises, both functioning as monopolies. Systembolaget is the state owned monopoly for marketing of alcoholic beverages. Svenska Spel is the state owned gaming operator. Svenska Spel's task is to provide citizens with gaming products. Both companies are expected to market their products and services while taking caution and minimize damages, but are also supposed to deliver various degrees of economic revenue.

Syftet med denna studie var att undersöka hur ett pedagogiskt spel för grundskolans senare år som övar geometriska begrepp kan utformas samt huruvida det kan fungera som ett givande komplement till befintliga material för geometrisk begreppsinlärning. Spelet, som kom att kallas MATERMINO, testades av 33 elever (15 flickor och 18 pojkar) i skolår 6. Dessa elever samt tre lärare för grundskolans senare år bedömde sedan spelet; de förstnämnda i enkäter och de senare i intervjuer. MATERMINO bedömdes främst passa elever i skolår 6-8. Vidare visade studien att MATERMINO var omtyckt och roligt och att spelet tycktes leda till inlärning gällande geometriska begrepp.

This master essay is about teenagers, alcohol and the preventing measures taken by the Swedish government. Consequences of the rising consumption of alcohol among adolescents and how to prevent dangerous alcohol consumption in the future is one of the most prioritized issues in the Swedish society today. Today there is no prevention that clearly shows any effect on teenager?s alcohol consumption and the education about the dangerous effect of alcohol is clearly not the same in schools around Sweden. To gain knowledge about how teenagers view their own consumption of alcohol we have used the Grounded Theory.

This project was initiated by a veterinarian, that at stallion performance tests for breeding during a number of years, noted breed differences in various types of testicular disorders. Therefore it was of interests to examine the proportion of testicular disorders within certain breeds. The aim with the project was in a first part to study cryptorchidism in common horse breeds in Sweden. Information about castrations of stallions performed during a 10 year period (2000-2009) was collected from computerized case records at five animal hospitals. The case records showed the numbers of castrations, normal cases and cases preformed on stallions with cryptorchidism, abdominal respectively inguinal.

AbstractThe debate on grammar has been on the agenda for thousands of years. Several different arguments and theories have been used in order to explain the importance of grammar in school. Some newer arguments have been added, while others have stayed, either in their original version, or in a modernised one.This essay aims to clarify the role grammar play in school. In order to do that we have looked into its history, the curriculum, modern research and interviews made with active teachers.The results of the literary studies, the studies of the curriculum and the field studies show that the very presence of grammar in school is disputed. The curriculum of today speaks of an orientation in language, with grammar as a part of it, based on the students? own language.

The aim of this study was to increase the knowledge about whooper swan (Cygnus cygnus) ecology to enhance the ability to predict and also to prevent the crop damage they cause. The largest proportion of damage in Sweden has been reported at stopover sites during spring migration in February, March and April. Therefore, this study focused on an important stopover site, Lake Tysslingen, situated in south-central Sweden. Specifically, the relation between the duration and period migrating swans stage at the stopover site and mean temperature (measured at three different weather stations) for the years 2001-2010 was studied. Furthermore, the swans´ selection for certain fields in relation to field type, distance to roosting site, a supplemental feeding site and forest edge within agricultural land surrounding the lake was analyzed.

Efforts to achieve a moisture proof construction process have proved to be considerably complicated, despite the knowledge and awareness that now exists within the moisture field. Materials, documents, templates and checklists are designed to be accessed but are not used anyway. This may be because such effort has not been prioritized and properly requirements have not existed from the commissioner of a building.This report illustrates how the commissioner of a building project can achieve a moisture proof building process by increasing knowledge, moisture proof planning, and implementation of security moisture routines. Proposals are given on how the commissioner of a building project can work to consistently bring a moisture proof building process in all stages. The difficulty with regular moisture proof efforts, the authors believe is mainly due to the following points:      Many different design solutions.      Lack of experience feedback.      Lack of communication.      Financial incentives.      Attitudes.The interviews in the report have conducted with the help of a qualitative analysis, while the survey has been done using a quantitative analytical method.

The aim of this study was to describe and analyze the participation of immigrant organizations to the partnerships in the Equal program in Sweden. The focus of the study was on the significance of the participation for the organizations and its impact on them. The point of view of the participant organizations has been object of study through interviews with the persons who, on behalf of the organizations, have been in charge for the work with Equal. Interviews have been conducted with people representing 10 of the 21 immigrant organizations that have been identified among the Swedish Equal partners. Many organizations have experienced that the participation has strengthen the awareness of target groups about their needs and their possibilities.

Syftet med detta arbete är att kartlägga ytjämnheten på stålbanden efter kallvalsning samt hur den erhålla ytjämnheten påverkas av trimvalsningen. Detta för att undersöka om det är möjligt att minska ner användandet av någon valsyta i Tandemverket vid SSAB Borlänge. Genom att mäta ytjämnheten på stålband av olika kallvalsade kvalitéer efter kallvalsning och trimvalsning, mäta ytråheten på texturerade valsar före och efter användning samt genomföra test med nya ytkombinationer har ett antal resultat genererats. Två test där Docol 200 band som skulle levereras med bandyta 23 valsades med en grövre yta i Tandem (valsyta 48 istället för 34) än vad som är brukligt och sedan trimvalsades med ordinarie valsyta visade att det är möjligt att klara kraven på Ra-värde för bandyta 23 även på band som kallvalsats med en grövre valsyta än i vanliga fall. Dock är det inte säkerställt att kraven för yta 23 alltid kan uppnås på band kallvalsade med grövre valsyta.

This is a thesis project in the field of information technology which begins by evaluating existing food price comparison systems and subsequently aims to design an improved, web based system for said purpose. The system features interfaces for price reporting, price comparisons as well as various search and review functions. The objective is to create a system able to compete with existing price comparison systems, which requires careful selection of products that can be found in all foodstores that also represent different households; a user-friendly price reporting and price comparison interface and an efficient tool for ensuring the validity of reported prices.The designed system features a more accurate formula for calculating average prices in events where the real price is missing; a more reliable security mechanism forv alidation of reported prices and a more comprehensible interface for viewing price reports, reporting prices, reviewing stores and products in comparison with existing systems. The system does, however, suffer from some optimization issues primarily in the form of inefficient database modeling; SQL queries and JavaScript code although testing has shown that these shortcomings do not hamper overall performance to such a degree that usability is compromised. Further usability testing performed on the system with five test subjects shows that a high level of overall user-friendliness has been achieved even though some special features, such as the detailed report containing price information per product for each store need to be improved.It is not possible to say at this time whether or not the designed system will be able to compete with existing ones or if the very concept of food price comparisons per se is viable in terms of profitability and marketability.
