Miljöteknisk undersökning enligt MIFO : en studie på fastigheten Bodsjölandet 1:14 avseende den nedlagda tjärfabriken i Grötingen

During 40 years of industrial production, from the end of the 1890?s until the end of 1930?s, coal and wood distillation products were manufactured in AB Carbo?s tar factory along the River Gimån in Grötingen, in the county of Jämtland, Sweden. In accordance with the Swedish Environmental Protection Agency?s Methods for Inventories of contaminated sites, MIFO, the site in Grötingen has been identified as a potentially contaminated site. In order to determine whether toxic substances pose a threat to human health and ecological systems in the area, there was a need to investigate the presence of contaminants, their levels and potential for migration.

I Gripdjurets grepp : om skandinavisk djurornamentik, bildtolknings metodik och djurhuvudformiga spännen

Animal art is one of the more mystical aspects of Scandinavian Iron Age culture. It has foremost been regarded in the light of art and style history. Interpretation has also ? mainly from the 1990s and onwards ? been made through iconographic analysis. But the problem here is that iconography requires textual analogy, something that the Scandinavian Iron Age lacks.The purpose of this paper is to lift some of the ?mystical fog? that engulfs the scandinavian animal art, by developing a method for interpretation of pre-historic images that evades the flaws in the iconographic method.

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.

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.

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.

En intuitiv & lättillgänglig flyktmask för gruvmiljö

I have always lived around mines and around people work­ing with mines. They are a natural part of my life and, inev­itably, a great interest of mine. When time came to make a decision for a degree project, focusing on the mine context felt as natural as breathing.In LKABs underground mines, safety in fire accidents is a great priority. Of outmost importance for the escape is to have a personal gas filter for filtration of smoke and/or gas. My design project resulted in a concept which is aimed at shortening the user journey from the start of the accident until the user has applied the personal safety solution and is ready to escape.Throughout the project I?ve been working with a context which is heavily regulated, and all problems are serious, important ones.

Lyfta Lätt Tekniskt hjälpmedel för pakethantering

People working with handling parcels in terminals are often victims of musculoskeletal injuries. This is largely due to the hazardous lifting of too many parcels which are too heavy and unsuitable work postures. The human body?s ability to lift and grasp objects is so outstanding that developing a device with the same capability is very difficult.The goal of the project has been to develop a technical device that will improve the handling of parcels with regard to ergonomics. The area of concern was the lifting of parcels between the conveyor belt and the cargo space of the freight car.

Testbänk för luftlager

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.

Solenergi i Norrra Djurgårdsstaden

This report will examine various solar energy technologies in order to decide if they could be applied in the Royal Seaport. The Royal Seaport is a Swedish urban district under development in Stockholm, with the goal of becoming a sustainable district. Two main techniques, solar collectors and solar cells, including sub-categories, are addressed in this report. Another sub-category, a hybrid system, will also be mentioned. The main difference between solar collectors and solar cells is the type of energy produced by the system.

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.

Jag förföljer dig inte, jag följer dig fina du! : En essä om förskollärarens profession och solidaritet

This essay is about my meeting as an educator at a preschool with a child who is deemed to be in need of special assistance. I have worked in preschools and schools for nearly fifteen years and have met a great many children with different needs during these years. I tell in this essay about my relationship with Lucas who is a child I feel need special support in his everyday life. Lucas has what we in the preschool world call impulse controlled behavior. I also feel that he is disturbed by external stimuli such as sound and he has difficulty with social interactions with friends.
