Askåterföring i Jämtland : biobränslets och askans innehåll av tungmetaller relaterat till markernas geokemi
Using biofuels from regeneration cuttings is becoming more common in Sweden. Ash from the combustion of biofuels contains many valuable nutrients and base cations. The Swedish Forest Agency recommends that ash should be recycled to clearings where biofuels have been removed, to avoid future impoverishment of Swedish woodlands. In Jämtland, in northern Sweden, a large quantity of biofuels are taken out from cuttings but ash recycling has not yet been tried. The aim of this thesis was to examine the conditions for ash recycling in Jämtland regarding to soil chemistry and heavy metal content in soil and biofuels.
Teater som forum för elevers sociala och konstnärliga utveckling : Ett relationellt perspektiv, en inkluderande verksamhet och interaktiva processer i teater på gymnasienivå
AbstractMaterial collected or created through observations, discussions and interviews with a group of students studying theatre in the fist year of upper secondary school formed the base for this paper. The students that took part in the observations showed a variety of motivations for the studies in theatre, but the major aim was to obtain qualifications for further studies at university. Special focus was put on a student with dyslexia attending the course in theatre from the perspective to strengthen general learning abilities. The training and teaching in acting skills as performed in the theatre studio provided the arena for the observations. The aim was to investigate if an interactive process as defined by Lev Vygotskij and the acting method created by Constantin Stanislavski would create social and artistic development among the students in the study.
Differentiering och framgångsfaktorer på en ständigt växande marknad : Undersökning av bemanningsbranschen
Today it is mandatory for every college or university student to pay a union fee to their student?s union. The fee is mandatory and is a payment for writing examinations, receiving grades. The fees purpose is also intended to secure the education quality and student influence. In the presence of the abolishment of the union fee the Swedish student?s unions stand before an uprising competition between themselves and most likely a decrease in membership.
Konceptstudie av drivmodul till bandskotare med hybriddrift
BAE Systems Hägglunds has a long history of producing high performance terrain tracked vehicles (mostly for military applications), and they are now aiming at developing a tracked forwarder with similar techniques.The forwarder will be of series hybrid type where a diesel engine via a generator will power the motors (one for each drive wheel). Thanks to individually controlled motors and the gentle rubber tracks, this forwarder is calculated to have a considerably higher average speed in the terrain and to be more gentle to the soil. The forwarder with a weight of 11 metric tons and a load capacity of 15 metric tons is specified to have an average working speed of 7-10 km/h, a top speed in terrain of 15 km/h and a top speed on roads of 40 km/h.This master?s thesis aims at developing a conceptual design of the forwarder?s drive module which includes electric motor, gear unit, brake and drive wheel.To investigate if the requirements can be fulfilled a study of the dimensioning loading scenarios has been carried out. The resulting needs regarding the torque has been considered in order to determine the required gear ratios for different motor options.

ECG-Screening for young elite athletesAbstractBackgroundSudden cardiac death (SCD) during physical activity is a frightening and emotional tragedy that draws huge media attentions when it occurs. Fortunately it is a relatively uncommon occurrence but happens nonetheless to young athletes who often seems to be in perfect health. SCD is used as a term for sudden unexpected complications on the cardiovascular system that leads to a deadly outcome normally within the first hour of onset of symptoms and the cause is some sort of underlying cardiovascular disease that gets triggered by physical activity.Normally athletes gets divided into two groups dependent on age, over and under 35 years, and this studies focus is on the younger group since it is often during this period athletes are at the elite level. It is also in this category the most unexpected sudden deaths occur that is not due to coronary atherosclerosis, which is the dominant cause of death, and drastically increases, for people over 35 years old.AimThe aim of this study was to scientific and unbiased analyze peer-reviewed clinical articles todescribe the pros, cons and cost to implement an ECG-screening as a standard before physicalactivities for specifically defined elite athletes.MethodA systematic review was performed and after all data collection 21 articles was chosen to beused as a base for both background and analyze. At the end 10 articles was fulfilling the criteria to be used at the analyze and later the results.ResultsThe implementation of ECG-screening has reduced SCD in Italy by 89 % between the years 1979-2004.
Hur nöjd kan man vara? En kvalitativ undersökning av inställningarna till intern information av anställda på SDF Tynnered
Background and Problem discussion: Strategic evaluations are important as they providecrucial information regarding Swedish development assistance and recommendations on howto face problems and inadequacies found in the evaluations. Therefore, the follow up ofrecommendations is of great significance as well. Unfortunately, SIDA?s ManagementResponse system for follow-up of strategic evaluations has not been functioning in asatisfying way and needed actions have not been taken. Thus, Swedish developmentassistance has been criticised for the lack of implemented actions and the public has startedto question the work carried through by the organisations.

Utveckling av processparametrar inom en hårdmetallindustri
This report analyzes and examines a hypothesis for finding a method to optimize thelength of the delubrication process time based on a total charge weight. The work hasfocused on the holding time for delubrication and the total charge weight.An important step in the manufacturing chain of cutting tools is when the greenbodies undergo the sintering process. Today, the delubrication step has the sameprocess time independent of the total charge weight. An implementation of a methodto adjust the delubrication process time would give more consistent quality of thecutting tool´s internal characteristics but also reduce the time course of the sinteringprocess. In the present project two methods for this goal were tested, thedevelopment of an algorithm and a weight interval subdivision with associateddelubrication process times.During delubrication a pressure increase is observed due to the decomposition of thePEG in the powder mixture.

Kommunernas politisering : En studie av det politiska styret i Nyeds landskommun 1950-1962
This essay deals with the question of lines of development within the politics in the rural municipality of Nyed 1950-1962. The aim is to explore how local politics and policies were handled from two perspectives. Firstly the issue of conflict and consensus or majority rule and consensus. Here Arend Lijphard's theory of majority and consensus provides a theoretical base for the essay. Secondly the aim is to explore the actions of the local politicians with regards to leisure time policies to find out whether or not they ideologically belonged to the concept of ?folkhemmets kommun? by Ulla Ekström von Essen.The source material for this essay has been the minutes from the two major bodies of local politics in Nyed, kommunalfullmäktige and kommunalnämnden.
Framtagning av beräkningshjälpmedel för tvärkraftbelastade förband med förbindare av metall.
The governing set of regulations for structural engineering in Sweden used to be Boverket, BKR. However in the beginning of the 21st century a changeover to new regulations, the Eurocodes, started.The transition was completed in year 2011 when the Eurocodes became the mandatory design work policy for all countries within the European Union. The Eurocodes were implemented to simplify and remove potential barriers to trade that may exist when countries have different design rules. Since the changeover it has been important for all construction companies to update their knowledge base and their design software.When comparing the two calculation processes they seem similar, but there are a couple of differences worth noting. With the new regulations, engineers will find that the process when designing joints in timber structures has changed. What used to be a fairly easy and straight forward calculation procedure has now become tedious and time consuming.The objective of this degree project is to present a product, a dimensioning tool that will help structural engineers when computing lateral load carrying joints in timber structures.The degree project is made up of two parts where the first part is the written report describing the background and theory behind load carrying computations. The second part of the project is the actual dimensioning tool which includes several worksheets in Microsoft Excel. The program treats single and double shear connections of the following:Nail jointsScrew jointsSteel plates (thick and thin types) The user can edit the following parameters:Type of plate/ number of shearsStrength class of timber membersMember and plate sizeType of fastenerDiameter of fastenerLength of fastenerYield moment of fastenerkmod and partial factors for design load carrying capacityThe dimensioning tool was created and developed in collaboration with structural engineers at the company Byggteknik AB.
Barnbibliotekariers förmedlingsarbete med lättläst barnlitteratur
The purpose for this Masters thesis is to describe childrens librarians work in supplying literature to children with emphasis on easy-reader materials. Our main questions are: · What do librarians believe characterizes an easy-reader book, and what do they base their decision on when classifying a book as easy-to-read? · How have the libraries in our study solved the hands-on difficulties associated with easy readers childrens literature? · Which factors do librarians consider to be important when supplying literature to children that are not used to reading or are not good readers? The theories we have used are Aidan Chambers Reading Circle and Karner Smidts view on the librarians professional roles when supplying literature. We have used a case study method, which means that we have gathered information through observation, objective papers and interviews. This has been done at six libraries.
Korsförlamning : etiologier, diagnostik och terapi.
This report is a literature review that aims to describe marketing contexts for mango production in Kenya. The institutional conditions in the country are not well developed for marketing purposes, which causes many difficulties and problems for the society. In Kenya most mango producers are poor small-scale farmers with limited resources. Mango is a perishable commodity and to keep its value and quality it is essential to have the opportunity to sell the mangos in the right time. Inefficient and undeveloped infrastructure and marketing systems hinders the mangos to reach the market in time though, which causes large losses of produce.The Kenyan mango production has increased during the last decade but due to market losses for the producer, the small-scale farmers? profits have not improved.
Styrelserepresentation för kvinnor i börsbolag : En naturlig utveckling genom självreglering eller en utopi i behov av lagstiftning?
This thesis aims to study whether the Swedish corporate law is in need of additional rules regarding the composition of the board of directors from a gender equality point of view. Sweden is internationally a state that is far ahead when it comes to creating equal opportunities for all its citizens. The Swedish labour market consist of men and women to an equal degree, although this is a phenomena that is not reflected on the leading positions in the larger limited corporations listed on the stock exchange. This is a trend that definitely needs to be attended to, since women can provide crucial knowledge that is important not only to the individual corporation but also to the society as a whole. This is strengthened by the fact that demographic differences in boards stimulates creative solutions and well reasoned suggestions.The opponents to legal measures regarding affirmative action base their arguments on the fact that the shareholders right of ownership is limited as a result of such measures and also that rules regarding self-regulation through corporate governance is preferable.
Älvkarleby, landskapskaraktär och gestaltningsförslag : landskapskaraktärsbeskrivning med inspiration av metoden Landscape Character Assessment, med riktlinjer och gestaltningsförslag
Älvkarleby, landscape character and design proposal is a Graduated Thesis (30
ECCcredtis), in the subject of landscape planning at the Swedish University of
Agricultural Sciences, the Department of Rural and Urban Development. This
thesis is a study and implement of the method "Landscape Character Assessment"
(LCA), developed in England and Scotland as tool to analyse and highlight the
landscape in different planning processes. The purpose of LCA is to increase the
understanding and strengthen the role of the landscape.
The thesis consists of three main parts: landscape characterization, guidelines
and a design proposal. The landscape characterization emphasizes the values
of the landscape in different types of planning processes, a documentation to
base estimations on in any kind of change in the area. Theese estimations have
resulted in guidelines that give proposals to the development of the landcape,
focusing at the desingproposal.
