Jämförelse mellan en träbro och en betongbro : En LCA-analys med fokus på koldioxidutsläpp samt en LCC-analys
This report is a thesis for collegeengineering program in structuralengineering at Uppsala University andwas commissioned by the Swedishcontractor Svevia. The study aims toprovide an overview of the mostbeneficial bridge material from bothenvironmental and economic point ofview.The life-cycle analysis covers onlycarbon dioxide emissions, since it isthe most spoken of in today?s climateagenda. Furthermore, this study aims tohighlight which parts, of the systemboundary, that contributes to greatercarbon emissions for the wood- and theconcrete bridge.The life-cycle cost analysis wascalculated with a lifespan of 40 yearsand covers the basic cost of investment,operating and maintenance, anddecommissioning costs.The analyzed constructions in this studyare existing projects that are almostcompleted. Both bridges were designed tohandle loads up to 60 tons.
Vinster med björkinblandning i granbestånd i syfte att höja markens pH-värde
The soil acidification and the pH-value of the soil have been discussed for many years. Many observations of the tree species effects on the soil pH have been done.
We have discussed the effects on the soil surface pH-value with a birch (Betula spp. L.) admixture in Norway spruce stands (Picea abies L.).We have used data from the Swedish National Forest Inventory. We have also discussed how the wood production and the biodiversity can be increased in mixed stands, in according to the Swedish forestry act Skogsvårdslagen. Our sampling areas are located in Norrland, Sweden.
The results show a significant correlation between an increased birch admixture and an increased pH-value of the soil.

Bostaden och de boende
AbstractWe all have experience of dwelling, which means that everyone can have an opinion about the architecture of the dwelling. Today the building companies do not have time enough to investigate which architecture qualities their clientele ask for in their apartments. JM AB use to call their apartments ?generous city apartments?. But do these apartments fulfill the needs of their dwellers? And what would the apartments look like if they were designed according to the wishes of the dwellers? When JM AB get knowledge about the dwellers needs and wishes they can make even better apartments for their future customers.The purpose and the objective with this report are to draw up proposals for tenant owner flat.
Made by China : Outsourcing av Konstruktionsarbete till Kina
Outsourcing means to contract out work previously done within the cooperation to a supplier.This is an increasing trend today. Traditionally companies have outsourced manufacturing butwith the growing specialization they tend to outsource other activities as well.China?s economical reforms and entrance into the World Trade Organization, WTO, hasenabled international business connections. Since China offers one of the cheapest labours inthe world, many companies have an interest in starting up an activity in the country. Themany foreign investments in China have lead to an economical growth which in turn hasmade it possible for China to invest in the Chinese competence and innovative capacity.The commissioner of this master thesis, SMS, is one of the leading actors in retrieval ofamong other things mounts and stands for flat screens and projectors.
Landscape urbanism : from a methodological perspective and a conceptual framework
Landscape urbanism has for the last decade been a topic for debate among practitioners and theorists involved in forming the contemporary city. The advocates for landscape urbanism mean that traditional dichotomies like city and country are invalid to illustrate the contemporary urban realm. Rather, a new urban morphology has evolved, which calls for new methods and models when approaching the city. Landscape urbanism suggests a revaluation of landscape in order to develop these approaches. This paper sets out to map how this is addressed within landscape urbanism.
Påverkan av skogsbrand på litiska arkeologiska fynd ? experimentell simulering av brand
This is a paper about the effects from smoldering fire on lithic objects from an archaeological view.
The introduction gives the background to this paper, a short orientation to forest wildfires and why the work is limited to: flint, quartz, quartzite and slate. Material and methods describes the stone materials and the setup that was used in the temperature logged tests with three replications for each type of material. The fuel in the burnings was peat on a bottom of sand. Flint showed a more drastic effect from heat compared with the other materials. Slate seems to have greater tendencies to change to darker colour and luster at lower temperatures than the other materials.
Analys av prispåverkande faktorer på bostadsrättsmarknaden i Uppsala
AimThe purpose of this study is to analyze factors that affect the price on tenant-owner apartments in the central parts of Uppsala. Special attention is put on analyzing how the monthly fee and the location affect the price. The hypotheses are that the monthly fee and the distance to the central part of the city have a negative effect on the price. A number of additional price affecting factors was taken in consideration during this study.MethodThis study is mainly based on data supplied to us by Mäklarstatistik. The supplied data consists of information about tenant-owner apartment sales in Uppsala during a year under 2008 and 2009.
Lyckade friskvårdssatsningar : vad är hemligheten?
The increasing health problems in our society have been lifted to the surface and debated for quite some time now. Even though the statistics of bad health somewhat have dropped, the problems still remain. Many companies are wrestling with this and are suffering from huge financial losses due to the costs of people frequently calling in sick for work. This has resulted in an increasingly high expansion of different types of preventive measures in order to avert health problems. But far from all companies reach these goals and it is there for of high value to study how important resources can be used in a more efficient way.The purpose of this study is to achieve a deeper understanding for Health promotive services in companies and to understand which influential factors are crucial in the process of reaching successful strategic Health promotions.
Traditional market segmentation - an evaluating approach
The purpose of this research is to evaluate traditional market segmentation variables, as criticism has been directed towards these variables. Based on our problem discussion we find it motivating to undertake investigation in order to understand which connotations an ethnographic approach will provide. Methodology:We have applied an ethnographic approach, which has enabled us to attain under the surface knowledge from our respondents. Theoretical perspective:As we wanted to evaluate existing traditional segmentation variables, we decided to only include theory regarding these variables. Empirical data:In order to collect our data, we observed seven respondents at Ikea and conducted observations and in-depth interviews in their homes.

Test bench for air bearingsThis thesis work consisted of bringing forward and defining the test parameters relevant for a test bench and constructing a test bench that can test and verify the largest existing air bearings that are of use in Micronic Laser Systems AB machines. Because the knowledge about air bearings is limited it is thought that with the help of the test bench the knowledge would increase and in that way improve the air bearings.After learning more about air bearings and their purpose at Micronic Laser Systems AB, I started the concept phase for the test bench. For each part in the test bench I consulted my two tutors, Torbjörn Hedevärn and Johan Bergqvist, at Micronic Laser Systems AB. The final concepts where documented as 3D-modells in Solidworks and some of them have been tested in Solidworks FEM-program.The test bench is designed so that, with the help of a pneumatic cylinder, 25 kilo weights are placed on the air bearing to test its stiffness, damping and the pressure performance under its surface area. To test these parameters the test bench has to have a pressure meter, accelerometer and a microcator.
Ett förslag till arbetsmöbel för användning i det offentliga rummet. : -examensarbete i samarbete med Nola AB
During spring 2007, I Matilda Lindblom, undertook my Bachelor Degree project in Furniture Design. The supervisors were Agneta Stake at Nola in Stockholm and Leo Jóhannsson, teacher and examiner at Carl Malmsten CTD in Stockholm.The project was based on three elements:? Cooperate together with a producer for professional supervision? Learn to work from a given design brief.? To learn more about industrial production? Learn more about furniture for public areasI contacted a furniture producer called Nola AB, in Stockholm, who became my work partner during this project. The asked me to design a piece of furniture where you can sit and work with a laptop on. The target was for public areas, for example in parks, malls, or at airports.In cooperation with Nola, my ambition was to develop this piece of furniture that was the answers on their wishes and demands.
Numerisk modell för global transport av spårämnen i atmosfären
The aim of this project was to develop a numerical model simulating the global transport of air pollution. The model currently used by SMHI, the Swedish Meteorological and Hydrological Institute, was intended to perform such simulations at regional scales. However, the usage of a grid based on longitudes and latitudes makes this model work poorly in global simulations. The problem with this grid is that the nodes are concentrated near the North and South Poles. Due to this characteristic, the Courant, Friedrich and Lewy-condition for numerical stability puts a sharp bound on the timestep length.
Kan strålar av ljus tyda det förflutna? : Användning av Reflectance Transformation Imaging (RTI) för att tyda runinskrifter på Pireus-lejonet
This paper deals with testing the method Reflectance Transformation Imaging (RTI) on the copy of the Piraeus-lion in Historic Museum in Stockholm. The purpose is to find out if it is possible to gather more information about the runic inscriptions. RTI is a method that records the surface normal of individual pixels in a digital photograph by analyzing the impact of light coming from different angles of entrance. RTI produces sort of a 3D-image of the object. There will be an overview of earlier interpretations of the runic scripts written on the lion as well as an overview of Varangians in the southeast.
Grammar teaching - to be or not to be, that is the question : En kvalitativ studie om grammatikundervisningens plats i språkundervisning i grundskolans tidigare år
???This research traces the trajectory of those methods of teaching grammar that five different teachers in Swedish from Stockholm municipality use in their practice. ?Their both constructive and negative attitudes towards grammar were in fokus when looking after the connection between their own experience of learning/teaching native language grammar and the methods that they are actually using in their own classes. I was trying to gain knowledge and achieve the purpose of this research by means of a qualitativ method.
