Utvärdering av Hultdins prototyp för portabel bro (drivningsbro) :
Stronger demand has been put on forestry to show environmental considerations during harvesting. This is especially for crossings of brooks with sensitive elements and great care should be observed when they are to be crossed during harvesting by logging machines. For that reason Hultdins has constructed a portable bridge that can be used for those occasions. The bridge has been developed in accordance with wishes from SCA forest, since they have a great deal of brooks in their forests and in private forests from where they buy part of their wood supply.
The aim for this report is to investigate if this portable bridge can be of interest for the forestry market. The research has been made at SCA skog in Medelpad and Norrskog in Medelpad.

The purpose of the thesis project has been to use scientific methods for product development inorder to design a multi device that supplements Silva?s range of products.The project followed a product development process divided into four phases; Market Analysis, ConceptCreation, Concept Development and Construction.
Mobiltelefon utformad med EcoDesign
The environmental demands are increasing when it comes to product development. EcoDesign isabout minimizing the environmental impact of a product, considering the entire life cycle of it,without compromising other qualities like function or cost. In this master of science thesis amobile phone has been analysed with Ten Golden Rules in EcoDesign regarding production, useand End of Life. Also a functional and an environmental profile were made. The goal was tomake a new concept phone, based on the previous analysis, which communicates userfriendlinessand sustainable development.
Röster, blickar och möten : Om berättande och etik i Sara Lidmans Tjärdalen
Sara Lidman?s first novel, Tjärdalen (The Tar Pit, 1953), addresses ethical issues in a remote village in the north of Sweden. This essay discusses the novel?s narrative technique and the ethical aspects implied by the narration and aesthetic design. The approach is based on Adam Zachary Newton?s narrative ethics, which links narrative theory and method with an ethical perspective.
Optimeringsflöde av modelleringsprogram vid broprojektering : Analys av de tre modelleringsprogrammen Tekla Structures, Revit 2013 och Rhinoceros
This thesis treats Building Information Modeling, BIM, in the production stage. Brieflydescribed BIM is virtual model of a building object where all information about theobject is gathered. All the involved operators in the construction project have access tothe model and can gather or share information about the project. There are several waysto apply BIM in the production stage. This thesis primarily deals with visualization of theobject, preparation and planning, the ability to take amounts from the model andcoordination and clash control.The basic issue was highlighted by Byggdialog AB.
Motivation och arbetstillfredsställelse i ett monotont arbete : En kvantitativ fallstudie gjord på kassamedarbetare på Ica Kvantum och Coop Forum
Motivation, in an organizational context, is about whether the employees feel that their work is worthwhile, satisfactory and that there are opportunities for further development within the organization. However, motivation can be affected by a number of factors that originate from the employees? characteristics, the characteristics of the situation and the individuals perception of that situation. A factor that could lead to a low level of motivation is if the employee feels that his work is monotonous.Thus the purpose was to study the factors that lead to motivation and job satisfaction in a working environment that generally is considered monotonous and dull by investigating the target group cashiers at two Swedish grocery stores called Ica Kvantum and Coop Forum.In this study a quantitative method was used by the design of a questionnaire. The questionnaire was used to get a general idea of the factors that the respondents consider motivating in their work.The results and the analysis of the questionnaire show that you really cannot make any general conclusions since there are many different factors that lead to motivation depending on who you are as an individual and in what phase of life one finds oneself.
Hackerör på Sydsvenska höglandet : vad skiljer röjningsröseområden från celtic fields, stensträngsområden och bandparcellområden?
From the pre-Roman and Roman Iron Age, a number of different fossil agrarian landscapes can be found in southern Sweden - clearance cairn areas, celtic fields, stone-wall complexes and geometrically laid-out strip fields. With two different comparative analyses, this paper tries to explain some of the differences between clearance cairn systems and the other fossil field systemsThe shape of the early Iron Age agrarian landscape varies between different provinces of southern Sweden. At Gotland, celtic field systems were laid-out before 500 BC. In Småland at the same time, areas with clearance cairns were created. How can the difference be explained? The different physical appearance of clearance cairn areas and celtic fields can be explained by the different ways to handle the ard in till and in sandy soil.
Automation i Distributionsnät
As a part of Göteborg Energi?s work towards a smarter electric grid, the company has chosen to investigate the possibilities of automation in their middle voltage grid. In Europe, there are example cases where these technologies already are installed which many articles on the CIRED conference 2011 proved. Netcontrol Oy in Finland has, together with Tekla, created an automated SCADA system that Vattenfall in Finland today uses. The grid mainly consists of 10 kV open loop fed city grid and this automation is mainly designed for this type of grid.
Kemisk kommunikation hos häst
Feromoner är substanser som används vid kemisk kommunikation mellan individer av samma art. Hos häst har ännu inga feromoner identifierats men studier gjorda i Litauen tyder på att kresoler, ämnen som bildas i tarmen vid nedbrytning av bland annat aminosyror och som utsöndras via urin och avföring, kan ha feromon effekt hos häst.Syftet med detta examensarbete var att undersöka förekomsten av kresoler och andra substanser i urin och brunstsekret från ston i östrus med hänsyn till variation mellan dagar i brunst och mellan provmaterial.Prover samlades in från 8 ston under 10 brunster och vid tre tillfällen från ston i diöstrus. Uppsamling av flyktiga substanser från urin- och sekretproverna gjordes med ?Solid Phase Micro Extraction? (SPME). För separering och identifiering av substanserna användes gaskromatografi och masspektrometri.

Enkätundersökning till Älvdalens Besparingsskogs delägare
Älvdalens Savings Forest was formed in the late 1800's. During this time the country was conducting the first major land reform in Sweden, namely the redistribution of arable land through government action. In Älvdalen people saw an opportunity to form Savings Forest, that is jointly owned forests, where everyone would get part of the proceeds. The yield in the first place would cover were costs to manage and monitor the forest and to the measures to ensure regrowth and improve the forests. You could also use the proceeds to develop the area and make it easier for the population to manage their forest.
In early summer, a survey was sent to all the members of Älvdalens Savings Forest.
Effektivisering av byggproduktion med VDC och förstärkt verklighet : Streamlining construction work with VDC and augmented reality
Virtual Design and Construction (VDC) is currently used more and more within construction design and planning as well as construction as a streamlining tool aiming to improve communication and decrease the number of construction defects. VDC is constantly developing, but what comes next? The augmented reality (AR) technology is currently not used within construction in Sweden but should be considered as the next step in line regarding the integration of reality and digital information. Using this technology design can become reality even before it?s actually built.The purpose of this study has been to carry out an inventory of the existing AR technology and its shortcomings, and also to identify possible applications within the construction phase.
Högtempererat borrhålslager för fjärrvärme
The district heating load is seasonally dependent, with a low load during periods of high ambient temperature. Thermal energy storage (TES) has the potential to shift heating loads from winter to summer, thus reducing cost and environmental impact of District Heat production. In this study, a concept of high temperature borehole thermal energy storage (HT-BTES) together with a pellet heating plant for temperature boost, is presented and evaluated by its technical limitations, its ability to supply heat, its function within the district heating system, as well as its environmental impact and economic viability in Gothenburg, Sweden, a city with access to high quantities of waste heat.The concept has proven potentially environmentally friendly and potentially profitable if its design is balanced to achieve a good enough supply temperature from the HT-BTES. The size of the heat storage, the distance between boreholes and low borehole thermal resistance are key parameters to achieve high temperature. Profitability increases if a location with lower temperature demand, as well as risk of future shortage of supply, can be met.
Utvecklingspotential till en mer attraktiv bostadsmarknad : En teoretisk värderingsanalys av stadskvaliteter och dess relevans för bostadsbyggandet
Stockholm has in recent years experienced a strong population increase but despite that fact, the demand for housing has not been followed by enough housing contracts. According to forecasts, growth in population will further be continued upward. With more condominiums than rental units on the market, new apartments are too expensive to live in. This creates unsustainable problems for those in lower classes of society. Creating a housing market in the periphery of Stockholm is not sustainable from a social perspective.

SUMMARY
Establish a pasture
There is many valuable nature and culture landscapes in Sweden that has developed during a long period of time, throw natural processes or human use. Unfortunately lot of these are disappearing. My thought with this work is to explore the possibility to establish new areas with similar qualities. The motive for this is that attractive countryside biotopes are well worth to use as model to enrich the urban landscape.
Another thought has concerned the people that establish, build and manage landscapes and parks. They often have varied views, both coming from a difference in background and previous experiences.
