Konceptbyggande med standardelement
Syftet med examensarbetet är att hjälpa ett företag med att införa standardlittera för deras prefabricerade betongelement som ingår i deras Konceptet. Införandet av standardlittera ska resultera till att återfinna och gruppera deras betongelement i CAD-systemen. We did our thesis project at one of the most prestigious Swedish construction companies. We have examined the possibilities of doing sandwich elements to standard elements which would increase the degree of industrialization. The company has developed a concept that is based on a more refined process of industrialization.

Plantetablering och tillväxt för sådd och planterad tall 2-5 år efter markberedning med harv eller Huminmix-teknik inom Holmen Skog distrikt Norsjö :
The objective of this work was to compare the environmentally gentle soil scarification technique Huminmix (with possibilities to do track-grinding/HMMspår, long-scraping/HMMlångfläck and mounding/HMMhög) with conventional disc trencher, concerning seedling establishment and growth of direct seeded and planted Scots pine seedlings. Inventories were made during June and July 2005, in 34 seeded and 6 planted stands from 2000 ? 2004 (1- 5 years old) of lichen- and myrtillus/vaccinum-type in Holmen Skog AB´s district Norsjö in Västerbotten. The Huminmix-technique had been used for HMMspår in the seeded stands and for HMMhög in the planted stands (HMMlångfläck has been used from the year 2006 for direct seeding). The studied stands had been seeded with the same amount of seeds according to stand data.
Det nazistiska hotet i Tidens spegel 1932-1939 : Arbetarrörelsen i spänningsfältet mellan demokrati och diktatur
The purpose of this study is to examine the effect the Nazi threat had on the swedish labour movement between 1932 and 1939 and to enrich what kind of pre-understanding they had about the fall of the Weimar Republic and the upcoming and effects of the Third Reich.Brought by the development in Germany, a debate and struggle took place in the Social Democratic journal Tiden over the meaning of concepts and there ability, in the hands of demagogs, to overthrow democratic structures. The concept of socialism and its concepts attribute play a major part in this investigation. By establishing fields of tension such as - nation vs internationalism, socialism in theory and in practice, political democracy vs evolved democracy and the diverse principles of neutrality, the first principle meaning the defending of national boarders, the other meaning not only defending your own country but taking an active part in defending democracy in the world - I was able to observe the movement and change of concepts within this fields. The result showing that the concept of socialism and near related attributes, in the hands of national socialists had undertaken a wast change of meaning, which applied in the Swedish debate threatened to undermine the power and force of the Social Democrats applied in the political discourse in Sweden. To defend itself and strengthening the Social Democratic hegemony as well as maintaining the goal of evolved democratic expansion, they were forced to win the confidence and votes of the middle class.
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.

Konstlandskap : ett projekt om en konsthall på Bergdala gård, Kivik
Abstract
? What is an exhibition hall?
? How do you create tension between art and
nature?
? Why should an exhibition hall be situated in the
country
side; would that add to the experience?
? What are the conditions of exhibiting
contemporary art?
These are some of the questions I first asked
myself when I came to work with this project on
an exhibition hall outside Kivik, Österlen. These
questions brought me to new places, meetings and
ideas.
The team working actively to realize this
project, calls it ?Art by the Sea?. The team has
been working with the project since 2001 .
Utläggningsrapportering i en mobil webbapplikation
This report describes the implementation of expense reporting in a mobile web application. Two different types of expenses could be reported: remuneration and time deviations. In addition to the creation of new expenses, existing expenses should be able to be edited or deleted. The implementation would be designed in such a way that it prevents the user from making data entry errors in an intuitive way. The bachelor?s thesis was performed for Flex Datasystem AB in their mobile web application, Flex WebApp. Due to delimitations made during the project only functionality for the expense-type remuneration was implemented..
Energieffektivisering av aerbo reningsprocess : Tillsats av biprodukter i skogsindustriellt avloppsvatten
In the production of pulp, paper and cardboard, a large amount of water is used daily. The water has to be purified in the internal purifying plant before it reaches the receiving body of water. In the biological purifying stage at the Stora Enso Skoghall mill, an aerated basin is used where the microorganisms, using oxygen, oxidize the organic material to carbon dioxide. The air is pumped from the bottom of the basin and the oxygen can then be transported from the air bubbles to the water through diffusion. The problem with aeration of waste water from the forest industry is that wood residues, such as fatty acids, are making the transport of oxygen in water more difficult.

The purpose of the project is to with a usage-centered design method create a paper prototype of a tool that will help the employees to analyze the log files in a more efficient way than earlier.The result shows how the usage-centered design method was used to create the paper prototype and how the user interface was created according to human-computer interaction (HCI)..
Mindre studie av en ny gallringsmetod i stamtät förstagallring av gran i södra Svergie
The main purpose of this study is to investigate how to reduce the high, and every decade raising, pre-clearance cost. The pre-clearance is today carried out with a brush saw and paid per labour hour. All small trees not suitable for pulpwood are removed to simplify the later work of the harvester.
The study compares the economic results from thinning of four parcels each treated differently regarding harsh or light pre-clearance and extraction of only pulpwood, or both pulpwood and fuel wood.
In this type of spruce stand the study indicates that a lighter pre-clearance, followed up with both pulpwood and a fuel wood extraction, has a much better economy than the traditional method of hard pre-clearance and only pulpwood extraction..
Frystorkning Kontrollerad torkning av kulturhistorisk dräkt?
Cultural objects may become wet by deliberate water cleaning, water disaster or watersoaked for other reasons. Air drying textile objects and even other organic materials from awater wet state, involves many problems depending on the strong capillarity action of water.Damages and changes such as bleeding of dyes, stains or lines of impurities from watermovement, shrinking or stiffness can occur. Freeze-drying as an alternative drying methodhas often been used for wet archaeological and marine objects, but more seldom for historicalmaterials.This bachelor thesis addresses the issue of whether freeze-drying can be an alternative controlleddrying method for historic costumes. Costumes and related objects are often compositeobjects, consisting of multiple materials, as well as being three dimensional, all of whichwill complicate drying. The purpose of this study was to investigate whether it is possible tohandle costume objects after wet cleaning for drying by freeze-drying, and if damages due tosurface tension of water, can be avoided in this way.
Blästring av trä : Ett materialbibliotek av blästrade och ytbehandladeträytor
In my thesis I have sand blasted different type of woods - ring-porous and diffuseporous deciduous tree species and conifers - to show different results depending on the species, the direction of the grain and the effects of surface treatment of a blasted surface.The results of my tests were sometimes unexpected, such as that the sand from blasting almost completely disappeared, that all wood surfaces after blasting exhibited a much lighter or paler surface than before and that the diffuse-porous tree species showed differences in hardness between the beginning and end of annual rings.By creating a library of different kinds of wood and sandblasted surface treatment, I have created a reference bank that I will be able to use me in the manufacturing of interiors, furniture and other objects..
Beslutsunderlag för energianpassade gallringar i Västerbotten
The demand for renewable energy is increasing in Sweden. This consequently increases the pressure for and willingness to pay for forest fuels. One method to extract forest fuel from suitable commercial thinnings is the "long top method? (LT-method). With this method saw logs and non-delimbed tops are recovered, i.e.
Grb10 and developmental programming: evaluation of a maternal diet restriction model during gestation
This study was conducted at the University of Bath, UK, from September to December 2014 as part of an ongoing research project aimed at elucidating how the Grb10 gene might act as a mediator of long-term health effects (such as predisposition to obesity, diabetes, coronary heart disease and hypertension) caused by environmental factors during development. This phenomenon is known as developmental programming.
The purpose of this thesis was not primarily to answer any of the broader questions posed by this research project at large since this would require much more data than is reasonable to acquire over the course of a few months, but rather to evaluate the methods used in this project and reveal whether they are working the way they are presumed to. In the research project, which employs mice with the Grb10 gene knocked out as well as wild-type control mice, a dietary restriction model is utilized during gestation, which is supposed to generate offspring with lower birth weight and subsequent detrimental health effects in adulthood. This is supposed to be achieved by restricting the protein content of the pregnant mothers? diet to 9 % (as opposed to the control diet of 20 %) throughout gestation.
