Due to the requirement for reduced use of insecticides and the lack of competitive mechanical plant protection, you need a scarification with good result. This is often no problem to perform in normal terrain without technical barriers. However, in difficult terrain with large number of rocks and steep slopes, the result would be worse. The purpose of the study is, that in these areas with difficult terrain, to find out the scarified areas quality, describe the non-scarified areas conditions and find out where the limit is for the use of a traditional disc trencher. Findings indicate that there are usually not the machine that is the limit, but the driver of this.

In 1994 a new Forestry Act was accepted in Sweden. One of the aims of the law is to raise consideration forpreservation of biodiversity. Since the new law got accepted and some time has passed, there now lie someinterest in examining whether the law has been effective towards its purpose. Methods suitable for analysishave been examined during this study. The content of this pilot study is based around five parameters whichcan be used to validate the effects of the new law.

It is important for today?s farmers to minimize the costs for crop establishment, because of decreased prices and support from the EU. Farmers, who plow in autumn on heavy clay soil, often do some kind of tillage in autumn to get better soil structure before spring seeding. This is especially important when growing small seed crop, e.g. sugar beet and oil plants.

The aim of the Master?s Thesis work is to study and develop algorithms for autonomous travel of a UGV (Unmanned Ground Vehicle). A vehicle for the mounting of sensors has been constructed in order to perform the work. Since the UGV is to be used outdoor in urban areas, GPS can be used. To improve precision and robustness, inertial navigation is used in addition to GPS, since GPS reception is likely to be diminished in such areas.

In this paper, generic reference in a collection of juridical texts is examined, with focus on third person singular pronouns. The object of the study is to find out which generic pronouns occur in the material along with their relative distribution, but also to display further use patterns and to offer plausible explanations for these patterns. Another object is to evaluate whether the use of generic pronouns corresponds with language planners? recommendations for non-sexist language. The corpus studied consists of Rikspolisstyrelsens författnings­samling (?Statute Book of the Swedish National Police Board?), comprising 172 documents written between 1974 and 2009.The study is divided into two parts.

To maintain production in high salaries countries and strength in competition against other companies, it is today more important than ever to maximize production, offer a wide spectra of products and be able to deliver on the customers desire of shorter and shorter delivery time. Flexible production and short time spent on die changes is vital to achieve these desires. The interest for die changeover time reduction grew in the same pace as the demand for increased product variety grew. SMED as a method of reducing time spent on die changeovers were developed in between 1950-1970, by the Japanese Shigeo Shingo.The purpose of this thesis work has been to investigate the result of SMED in a die casting facility, and compare the result from it with the result considering time spent on die changeovers when investing in new equipment. The goal is to implement a thorough investigation by using the SMED method at Tenhults Pressgjuteri AB and make a brochure that have to be simple to understand, in purpose to draw interest to the advantages of using SMED as a method.Commissioned by the Swedish foundry association Swecast, the work has been carried out by studying die changeovers at Tenhults Pressgjuteri AB, where filming and interviews with the operators have been included in the analysis.

Like many small-time companies there is a need to improve the flow of materials at HSP-Gripen AB. The company develops and manufactures hydraulic-powered grapples for the machine- and forest industry. By mapping the material flow in the current production and gathering necessary data, suggestions on how different parts of the production could be controlled is presented in this dissertation. This has been achieved by the study of relevant scientific literature. The suggested ways of controlling the production consist of 2-bin systems, hybrid material flow system as well as a cyclic product-planning.

The purpose with this project is to explore and verify three renovating systems for Miljonprogrammet (common expression forbuildings constructed during the years 1965-1975 when over a million houses where built in Sweden) to take measure to thelargely transmission losses of these buildings. Many of the buildings from this period have similar constructions and thereforethe same techniques can be used to renovate several of them. This project only considers the climate scale, although thereare many more factors to concern for to efficient the buildings of Miljonprogrammet.This thesis presents examples of renovations carried out using two of the three renovation systems.The essay presents a reference house of choice on which we apply the three systems and calculate the new U-values,consumption of energy and the investment costs. The new U-values the building is given is matched to the values ofrecommendation for passive houses. Our reference house is a two story apartment building, located in the village ofLammhult, with brick facades at the ends and plaster at the long sides.

PR appears to be an indistinct division and a complicated resource for companies to value. The current circumstances are negative to the credibility and reliability of PR. This study emphasizes how an application of return on investment contributes to a more strategic use of PR and increases the status and credibility for the division.We experience that measuring the economic value of PR is of great importance and of current interest with few prior studies made. The purpose of this study is to find out how a PR-agency and one of its clients relates to and works with evaluation of PR-activities and to which extent the economic contribution of the activity is measured.The foundation which the theoretical reference grounds on is theories of Delusions of PR and the use of benefit-cost analyzes, Stages and Levels for Evaluating Public Relations Programs, Marketing Return on Investment and PR Return on Investment. The theoretical reference serves as a base during the analyze of the study.The conclusion, based on the empirical body of information, is that an application of return on investment could contribute with a higher status and credibility for the PR-division.

In this thesis, two studies with different drills were included. In one of the studies two drills were compared: Väderstad Rapid and Väderstad Spirit. In the other study various drills for direct drilling were compared. The study with Rapid and Spirit was placed in two locations with different autumn tillage; one on ploughed land in Uppsala and one on cultivated land in Västerås, both with relatively high clay content. Rapid drills have a single disc coulter, while the Spirit drills have a double disc coulter. Various aspects were compared such as aggregate distribution, seed placement, emergence, crop yield and economic outcome.

The purpose of this report is to investigate the business relationship between forest machine entrepreneurs and company officials within a timber area at one of the Swedish forest owner associations called Mellanskog. This report shows how these people work with their business relationships, what they believe are the keys getting a successful relationship and how they have got were there they are now. Key words: Business relationship, cooperation, team work, communication, negotiation, respect, commitment and trust..

The purpose with this study is to find out how much dead wood we can expect us to find in a Russian reference river and compare with studies from Swedish streams. Dead wood are an important structure for the biodiversity in forest streams, studies have shown that population of trout can increase with up to 300 % when the amount of dead wood are increasing from 0 to 8 ? 16 LWD (Large woody debris)/100 m2. Dead wood are also an important structure for the stream character, formations of dams and pools which are important habitats and reproduction areas for salmon and brown trout. The study where taken place in tributaries to the Russian river Varzuga in the North West part of Russia outside Murmansk. Varzuga has low impact of human activity and is considered to be a reference river to rivers in northern Sweden.

This investigation?s task was to map manufacturing of special qualities at Stora Enso Packaging under a certain period, analyze if rules concerning special qualities is followed, which consequences this results in concerning use of paper, waste and costs and to give suggestions on alternative solutions. The goal was to give sugges-tions that help the company to reach its business ratio that the production de-partment uses within use of paper and productivity in the corrugated cardboard machine.Stora Enso Packaging is a part of the forest group Stora Enso and is one of Swe-den?s leading producers of corrugated cardboard. Stora Enso Packaging acts pri-mary on the Swedish market, where they have a market share of 25 %.To be able to analyze orders with special qualities we did a data collection during two months, where we mapped incoming orders.

Epiphany is a significant feature for a certain kind of short stories. In this essay Anna Westberg studies its importance for her short story writings in comparison to Alice Munro, one of the short story most prominent authors. The analysis is supported by a brief overview of the history of the short story and its development..

The purpose of this essay has been to examine whether attitudes and behavior among Swedish people who takes snuff are dissonant or not and how their attitudes are affected by the media debate about the health risks snuff can cause. Furthermore, we were interested in finding out how different reference groups´ attitudes would influence the attitudes and the willingness of people to stop taking snuff and investigate how much control the people who take snuff think they have. To answer these questions we chose to ask primarily students at Stockholm University and Södertörns Högskola. The students were asked to fill out a questionnaire with 22 questions and the 100 responses we collected were worked up in a statistic program, SPSS, on the computer. The main models used for the essay and for the questionnaire were the Theory of Planned behavior and the Dissonance theory.
