Har antalet naturvärdesträd i Sverige förändrats mellan 1999-2009?
Forestry and forest products are vital components of the Swedish economy but the forest is also important for recreation, hunting, out-door life and conserving biodiversity. The Swedish Forest Act has two equally important objectives, production and environmental protection. Polytax is the Swedish Forest Agency´s inventory programme which monitors progress toward the two objectives in connection with regeneration fellings. It includes data on environmental protection measures taken in connection with regeneration fellings. 30 § of the Swedish Forestry Act and related regulations specify the demands for conserva-tion of nature.
Etniskt diskriminerad i arbetslivet? : En fråga om trovärdighet
Archbishop KG Hammar has attracted attention for his liberal position in theology. His view on the role of language and communication is central in several books and articles he has published as leader of the Church of Sweden. One of his main theses is the fact that meaning is created in the encounter between text and reader. He often reiterates: God is relation. This non-traditional dynamic stance has a broad impact not only on theology.
Generation of mutated expression plasmid KRT1 and comparison of HaCaT cells transfected with expression plasmid KRT1 or KRT10 concerning keratin aggregates
Introduction The genetic skin disease epidermolytic ichtyosis is caused by mutations in either keratin gene 1 or 10 and leads to blisters and hyperkeratosis of the epidermis. At cellular level the disease is seen as aggregates in the keratin filaments. Since medicines are hard to investigate and produce mainly due to lack of reproducible model systems, there is no good treatment available for this disease today. In this article we describe how an in vitro model consisting of cells from a stable cell line transfected with expression plasmids to mimic patient cells, may be a possible alternative for screening compounds for therapies. The first step was to generate an expression plasmid required to complete the in vitro model.
Valfrihetssystem enligt LOV : Ur ett biståndshandläggar- och organisationsperspektiv
Sweden has one of the best elderly cares in Europe and the Swedish care work is also one of the best in terms of quality, compared to other European countries. In recent years, higher demands have been set on the care work and the number of privatizations of public services has increased. In 2009 a new law came into force, the Act on System of Choice (LOV) which increased individual?s right to a greater participation and a free choice in the selection of health and social care providers. This paper aims to highlight the impact of the law, system of choice.
Vilseledande Underhållning : Ungdomars Attityder till Dold Viral Marknadsföring
In this paper, we examine the attitudes of 16- to 19-year olds towards stealth viral marketing in the form of videos posted on websites such as Youtube. Apart from their general attitudes towards the phenomenon, we were also concerned with their views on the ethics involved in this marketing method and how this affects their view on the companies behind the advertising. To accomplish this, we administered a survey to a sample chosen by convenience. Using the Persuasion Knowledge Model and prior research on the subject, we then analyzed the gathered data and reached the conclusion that the respondents in our sample were mainly positive towards stealth viral marketing in this particular form, that they generally did not consider it unethical and that even though most considered the companies to be responsible for such videos, teenagers were not likely to take negative actions against them if they found out that a video that they had seen was in fact a stealth viral video..
Fysikalisk modellering av klimat i entreprenadmaskin
This masters thesis concerns a modeling project performed at Volvo Technology in Gothenburg, Sweden. The main purpose of the project has been to develop a physical model of the climate in construction vehicles that later on can be used in the development of an electronic climate controller. The focus of the work has been on one type of wheel loader and one type of excavator. The temperature inside the compartment has been set equal to the notion climate. With physical theories about air flow and heat transfer in respect, relations between the components in the climate unit and the compartment has been calculated.
Tillförlitlighet i Stockholms elnät : En analys med hjälp av Tekla NIS
Outages in the electric grid can be costly for society. Because of this, reliability is one of the parameters used to regulate network companies. Reliability in electrical grids can be measured with SAIDI, system average interruption duration index, which for Fortum Distribution has increased in Stockholm?s distribution network (11 kV) in the early 2000?s.By using outage data for Stockholm from 2011-2013, sets of parameters to be used for reliability calculations in the network information program Tekla NIS were derived. Two different options for investment were then analysed: changing old cables with high fault frequencies, and installing automatic switching in distribution substations.
Förändringsarbete i skolan - med lean som inspiration : Lean-tavla - för röd tråds skull!
During the middle of the 18th century the development of Toyota Production System, TPS, started in order to streamline the processes. TPS was based on the principles of assembly line production but unlike previous performers Toyota let the manufacturing be constantly affected by demand. At the end of the 18th century TPS was described by Womack and Jones in the book "The machine that changed the world - the story of lean producion" where TPS got the name lean. The principles behind lean is to maximize customer value and eliminate waste which means making products and services more valuable to the customer. 1Lean was for a long time a philosophy and an approach limited to industries and production based companies.
Simulering av hydrauliska dämpare i borrslagverk
This master thesis consists of the creation of shock absorber models for percussive rock drills. A model of the rock was also developed. These models were connected to existing models of the rock drill to create a complete simulation of the rock drilling process.When the models had been created the rock model was evaluated by comparison with measured values from lab tests. The verified rock model was then used to evaluate the shock absorber models.Four new shock absorber concepts have been developed. Three of these have been modelled, while the fourth have only been sketched and described.The evaluation of the models showed the following:? Simulations of the single shock absorber don?t correlate to reality very well.
Identifiering och reducering av köer i samband med återbesök
Purpose ? The purpose of this thesis is to develop a total cost model for container transports and create a tool that calculates a suitable transport quantity from an economic view, which fulfills the demands on delivery service. To achieve this purpose the following questions will be answered:Which costs are affected by the decision between the two transport alternatives LCL and FCL? How does the decision of sending product LCL or FCL influence the delivery service? How can a tool be constructed to simplify the decision-making process regarding the choice of sending products LCL or FCL? Method ? A total cost model was developed. This model is supported from existing literature.
Upprördhetens betydelser : Diskursanalys av en känslosam riksdagsdebatt
Today there are many students with behavioral and developmental disorders in schools. One of these disorders is ADHD. The medical designation ADHD stands for Attention Deficit Hyperactivity Disorder. I have chosen to research how two students with ADHD can be included in a fifth grade classroom.This research paper addresses the issues surrounding the student?s day-to-day life with a focus on the classroom.
Politiskt utanförskap : en studie av invandrarsammansättning, kommunorganisation och kommunpolitikers demokratisyn som förklaringsfaktorer av underrepresentation av invandrare.
The development that the Swedish society has experienced during the last four decades and the higher part of the population coming from foreign countries calls for a more intensive research on the situation of these groups. The purpose of this study is to find explanations of the differences in the share of immigrant politicians in Linköping and Norrköping. The starting point of the study is a model of factors assumed to affect the representation of immigrants in the municipality assemblies. The immigrant composition, the municipality organization and the view of democracy of the politicians, are all assumed to affect the civic participation. The civic participation is then assumed to affect the representation of immigrants in the municipality.
Stenmaterial vid asfalttillverkning
Denna rapport beskriver arbetet med utvecklingen av en ny modell för kaplanturbiner. Utvecklingen bygger på två kopplade differentialekvationer som under arbetets gång anpassats och implementerats i turbinmodellen.Modellen beskriver hur vattenflöde och turbinmoment påverkas av avvikelsen från den optimala kombineringskurvan för vinklarna på turbinens ledskena och löphjul, och är anpassad för ett referensaggregat med tillgängliga provdata. Även övriga enheter i vattenkraftaggregatet modelleras och sätts samman med frekvensregulator och elnät för att simulera aggregatets reglerstabilitet i önätsdrift.Verifieringen av turbinmodellen sker genom försök att återskapa de befintliga verkningsgradskurvorna med hjälp av modellen. Resultatet visar en god följning av de verkliga kurvformerna, dock med något lägre maximal verkningsgrad.Verifieringen av önätmodellen sker genom att prova stabiliteten i nätfrekvens och turbineffekt vid stegpålastningar. Resultatet ger en stabilare reglerstabilitet än i verkligheten, men uppfyller ändå förväntningarna på en fungerande modell.This report describes the development of a new kaplan turbine model.
Prognostisering av räntabilitet på eget kapital - Förbättras möjligheten att prognostisera räntabilitet på eget kapital om hänsyn tas till earnings management
Prior studies have shown that earnings management can be used either to inform or to mislead investors about the future performance of a company. However, few studies have examined the impact of earnings management on forecasting return on equity (ROE). The aim of this thesis is to investigate whether the ability to forecast next year's ROE is improved when taking earnings management, measured as discretionary accruals, into account. This is examined by comparing a forecast model that takes the magnitude of discretionary accruals into consideration with a model that does not. The study is based on companies that were listed on the Stockholm Stock Exchange during 2002-2012.
Höjdmodellering med laserdata : Studie av Kärsön, Ekerö med fokus på upplösning, datalagring samt programvara
The New National Elevation Model (NNH) is a new high-resolution digital elevation model (DEM) of Sweden from airborne laser scanning. It creates many new opportunities, particularly in the area of flood mapping. NNH is provided by Lantmäteriet in two formats, both in raw LIDAR (Light Detection and Ranging) data and in grid format with two meter resolution. These alternatives have advantages and disadvantages and the aim of this thesis research is to identify these. One of the focuses of the study is data storage and thus data structure analysis, resolution and storage facilities. The research questions are:Why and in what context the different NNH-products from the National Land Survey are used (DEM 2+ or point cloud)?What constraints and opportunities are created by the different options, mainly in terms of different software, resolution, and data storage?The study area is Kärsön in Ekerö municipality located in Stockholms län and has an approximate area of 25 square kilometers. The study is divided into two parts. The first objective is to identify the consequences of using different software to create DEM from pointcloud compared to the DEM2+ model. Height models with a two meter resolution are created in FME and ArcGIS. The models are then compared with the grid from Lantmäteriet, created in TerraScan. The second objective is to examine the impact of the change in resolution, both the storage aspect and both the accuracy aspect. Inverse Distance Weighted (IDW) is an interpolation method which in previous studies proved to have the best results on high resolution LIDAR data. This model was tested and compared with a model from FMEs built-in function and the model from Lantmäteriet wich are based on triangulation (also proved a good method in previous studies). The grid created in TerraScan has good properties such as accuracy.
