After the mandatory rules for clearing was removed in 1994, the clearing area has increased in Sweden. After the storms Gudrun and Per, the areas became planted with new plants, mainly spruce, but also other tree species. Storm areas are now being invaded by naturally rejuvenated birch in the tilling tracks. Since the birch often is initially growing faster than the spruce it is inhibiting the growth and is also damaging the spruce. The purpose of this thesis is to study the new brush saw with chain and compare it with the conventional clearing saw, mainly in terms of performance and ergonomics. The results show that the new brush saw with chain is very good in almost all clearing operations compared to the conventional clearing saw.

This thesis compares different methods for risk assessment of a creosote contaminated site in Vansbro, Dalarna. In a complementary study the importance of using representative data for calibration and validation of stationary groundwater models is discussed. The time dependency between surface water levels and groundwater levels on the site in Vansbro is evaluated by step response analysis. The results show that the groundwater levels reflect only long-term variation in the surface water levels. Hence the use of such long-term means for calibration and validation of the stationary groundwater models is the only theoretically defendable alternative.As a first step in the comparison of risk assessment methods the degree of contamination is evaluated on the basis of generic guideline values for contaminated soils, developed by the Swedish Environmental Protection Agency.

The project involves implementing a finished dispersion model into ArcGIS. The goal of the tool is to show how dangerous and toxic substances will travel in the ground after long periods. The goal of the project is to understand GIS in general, what it is used for and gain an insight into how developing tools for ArcGIS is, what challenges might exists. Understanding the type of data that can be stored and accessed in ArcGIS a long with the tools and functionality offered by the system when using Python as the main language for development. A prototype of the tool is created..

In this study we have examined the possible quality standards and methods for applications with service workshops in the forest industry. The purpose of the methods presented here was to start the work of standarardising the maintenance service in the industry and be of use for service providers in their quality effort.The methods we used to accomplish the study were interviews and field visits together with a comprehensive literature research. Our results are presented in the form of four solution proposals: a standard based on existing SIS standards for terminology and key indicators, checklists that are filled in by mechanics with customer participation, the construction of a instructions database, and the implementation of the method 5s.We believe our suggestions can help the service providers in the four problem areas that we have identified: long term strategy, documentation, recruitment of competent technicians, and standard procedures in their operations. These improvements will be beneficial for both the service provider and the customer..

This thesis aims to study the effects of the infrastructure project Västlänken in Gothenburg, a rail tunnel to be built through the city center. The study focuses on the community of Haga where one of the three exits will be constructed and also the surrounding urban environment, to see if the project can be sustainable. Sustainable urban development was selected as the theory, and the term "sustainable" is defined in this study using a number of criteria that two scientists developed. The criteria include economic, ecological and social perspectives on how a place or a geographical area can meet today's needs as well as possible needs in the future. The methods used were semi-structured interviews and content analysis of government documents. Interviews were conducted with various institutions in the city, and companies involved in the planning of the project in Gothenburg.

Establishment can be described in many terms. This term is about a company that is establishing on the European market. For many companies, this can appear as a difficult, time- and resource taking process but to advance and develop it is not enough to have a good position on the Swedish market. The company Akzo Nobel Nippon Paint AB, which this composition is about, has taken the risk to leave the home country and explore the unknown. The process was careful and long-termed but also profitable.

The purpose of this study was to describe experiences in daily social life of parents of children with psychotic illness. Five parents with long-term experience of psychotic illness have been interviewed. The frame of reference in emotion theories of Thomas Scheff and Randall Collins have been used to analyze the results. The study is qualitative and has a phenomenological approach to shed lights of meanings in daily social life. The following meanings was found: Openness with certain reservation shows that honesty is important for the feeling of solidarity, Social expectations in daily life describes the parents´own expectations as well as expectations from others.

During the past twenty years, the Swedish school systems have slowly changed to becomemore and more performance-driven. Private schools have been growing in general and, likeindependent schools and schools managed by municipalities, they profile themselves. Schoolsare becoming more performance and result-oriented, which has changed the roles of teachersin a dramatic way and is in general, still changing.By profiling students based on theirindividual performance, schools are able to help students identify themselves and their owngoals. The process of profiling is a slow one in which some teachers adapt more quickly thanothers, and one that is critical for other teachers to learn in order to keep up with the demandsof society.Schools, like ordinary businesses, are in constant competition with each other to keep up withthe newest and greatest models of teaching and to rank among the best in high achievements.Perhaps the downside of this modern school structure is that it is often difficult to have aschool where both school management and teachers see eye to eye. School management must heavily focus on the school?s results as a whole.

Due to the increase of the emission of greenhouse gas and climate changes more and more customers demand environmentally sustainable products. The increased demand of sustainable products from cradle to grave is something that has affected the food sector. Many retailers within the food sector feel that they are less or more forced to be environmentally friendly. Nowadays many retailers have chosen to show customers and stakeholders that they want to ?do good? by publishing annual sustainability reports. The Swedish food market has been one of many markets investing in being environmentally friendly.

SyfteSnusandet har ökat de senaste åren, särskilt bland kvinnor och yngre personer och till flera samhällsgrupper. Rökning har under många år genomgått rigorös forskning och därigenom bevisats vara förenat med ohälsa. Däremot är forskning på snusanvändandets hälsoeffekter eftersatt. En fysiologisk effekt som föreslagits av långvarigt snusande är påverkan på balans (posturalt svaj). Uppsatsens huvudsyfte är att undersöka effekten på balans av ett långvarigt (sex veckor) uppehåll från snus i en grupp av dagligsnusare. MetodI studien genomförde dagligbrukare av snus (n=13) tester av posturalt svaj före och efter sex veckors uppehåll från snus.

In the early 80s, several new synthetic materials have come to be used in the treatment of canvaspaintings, among them Plextol D 360, Plexisol P 550 and Beva 371. Today, many conservatorsfind the information about the long term sustainability of these binding mediums to beincomplete. Evaluation of synthetic materials is mostly done through clinical research, sometimesartificial aging is simulated. The correlation between artificial and natural aging is however notestablished, useful information can therefore be gained through evaluations of actualconservation treatments. The intention of this study is to find out more about how thementioned products perform over time in normal museum conditions.

This essay is about classroom environment, what kind of impact it has on pupils? learning, how to create a good classroom environment and how the style of leadership relates to the classroom environment. This is a qualitative study conducted by four informants.This essay is based on Lev Vygotiskijs perspective of the "sociocultural perspective", which is based on the theory that humans act upon their knowledge and experience, depending on the opportunities that the environment provides.The purpose of this study is to examine how three teachers, who teach younger ages, organize the environment in their classrooms. The goal of this study is to find out what the interviewed teachers perceive as good classroom environment. Also how the environment affects pupils? learning and what the teachers keep in mind when they furnish their classrooms.

This thesis examines the effects of proximity operators and query expansion with synonyms on retrieval performance. The queries were expanded with synonyms and structured with proximity operators where the permitted distance between terms varied from 1 to 3. The expansion terms were selected from the online lexical reference system WordNet. Initial query terms were selected from 28 topics that contained compound words and were chosen on the basis of their expandibility. The English morphological analyser ENGTWOL was used for normalization of query terms.

This report is the result of a thesis work carried out on the Risifrutti production at the company Procordia Food AB. The thesis is at a master level and is the final work for the author to receive a Master of Science in Innovative production at Mälardalen University. The thesis comprises 30 credits and has lasted for 18 weeks. The thesis is mainly a research on whether it is possible to perform an Environmental Value Stream Map (E-VSM) in a food processing industry and an evaluation if the tools E-VSM and Green Performance Map (GPM) are useful in this type of industry. An extra part to this research is to use the results from the E-VSM and give Procordia Food AB information on improvement potentials in the Risifrutti production. The author has found it difficult to collect some of the quantitative data to the E-VSM, mainly regarding energy, but by using the Value Stream Mapping (VSM) tool and other Lean tools the author was able to identify and quantify several wastes in the Risifrutti production. Recommendations for improvements based on these wastes have been given to the company. In the research part of this report the utility of the Value Stream Map, Environmental Value Stream Map and Green Performance Map in a food processing industry have been analyzed. The author has found that the Value Stream Map has been a useful tool since waste and unevenness in the tact of the production has been identified. The Environmental Value Stream Map and the Green Performance Map are also great tools when a company wants to analyze their environmental impact and then invest in environmental improvements. However, no profound energy analyzes has been done in the Risifrutti production because of the lack of energy meters for steam, electricity and compressed air in the production lines..

Performance Management är en process som syftar till att säkerställa att alla inom en organisation arbetar i samma riktning. Detta uppnås genom att öka tydligheten kring organisationens strategiska mål samt koppla dessa till medarbetarens individuella mål. Vidare är det viktigt att kommunicera vad som förväntas av medarbetarna i termer av arbetsprestationer samt hur detta skall uppnås för att lyckas med uppdraget att minska gapet mellan medarbetares arbetsprestationer och ledningens ambitioner (Armstrong & Baron, 2005).Uppsatsens övergripande syfte är att undersöka vilka erfarenheter ledare inom det multinationella telekom- och IT-företaget Logica har av att arbeta med Performance Management samt vilka delar av implementeringen som har varit lätta respektive svåra att genomföra. Vidare vill jag undersöka hur organisationen ytterligare kan förstärka arbetet med Performance Management-processen baserat på ovanstående.Den empiriska undersökningen har genomförts med kvalitativ metod i form av tre stycken fokusgruppintervjuer med ansatsen Experiential Focus Group. Som komplement till fokusgruppintervjuerna har analys av interna dokument som beskriver Performance Management-processen inom Logica, genomförts.Resultatet av undersökningen visar att ledarnas upplevelser av Performance Management-processen varierar beroende på vilken typ av arbetsgrupp man är ledare för.
