LuCoil Steel AB är ett dotterbolag till SSAB Tunnplåt AB. Företagets huvuduppgift är att tillverka Superstål, ett stål som ger lättare och starkare slutprodukter jämfört med konventionellt stål. LuCoil har blivit kontaktade av ett större företag gällande tillverkning av handsågblad. Genom att använda sig av ett högkolhaltigt kallvalsat stål från LuCoil skulle slutprodukten bli billigare då härdning av stålet inte är nödvändigt. Beräkningar när det gäller återfjädring efter böjprov visar att en sträckgräns på knappt 800 MPa räcker för att klara ställda krav på sågbladet.

This thesis deals with numerical simulation of earth pressure against tubular bridges in the software Plaxis. Plaxis is a FEM (Finite Element Method) software based on numerical calculations for which approximate solutions are developed through an iterative process. The program is specifically designed for soil and rock mechanical tests, such as voltage and deformation calculations in soil.The Royal Institute of Technology conducted in 2005, field tests on tubular bridges of corrugated steel, which was part of Ersa Bayoglu Fleners PhD (Bayoglu Flener, 2009). She studied how two different tubular bridges deformed during installation and filling. Tests and measurements were made during filling.

Erasteel Kloster AB Söderfors have been commissioned by the county administrative board in Uppsala län to make an inventory of possible contaminations in theirs industrial- and landfill areas on the basis of the Swedish Environmental Protection Agency?s; ?Method of Surveying Contaminated Sites-phase 1? (MIFO-fas 1). The inventory starts with maps and archive studies, place visits and interviews, and finally a risk classification is done. A risk classification is a compilation of four categories; pollutant toxicity, contamination level, possible spreading condition of the pollutant, sensitivity and protection value of the environment. In this paper five partial areas (Holmen- and Jörsöområdet, Järnsvampsområdet, Ingsådeponin, Östra verken and Myrområdet) have been described from a historical point of view. Only parts of four areas have been risk classified (Holmen- and Jörsöområdet, Järnsvampsområdet, Ingsådeponin and Östra verken), due to that the other areas isn?t own by Erasteel Kloster AB. Holmen- and Jörsöområdet Holmen- and Jörsöområdet have during the entire activity time been carried out as the production core in the company.

Det råder i dagens läge konkurrens mellan gatuträden och infrastrukturen. Människan som lever i den urbaniserade världen vill ha alla bekvämligheter inne i staden som kräver avloppsledningar, vattenledningar, gatubelysning, elledningar m.m. Samtidigt vill man ha gröna ytor i staden med stora pampiga träd. Oftast får dessa två, träden och infrastrukturen, slåss om platsen under marken och det är oftast det gröna som får lämna plats. Eftersom detta är ett återkommande problem vid de flesta nybyggnationer och nyanläggningar av ledningar, gator, parkeringar etc.

SUMMARY The interest of horses in the riding sector has increased the last decades. A large amount of horses are transported in a 1 or 2-horse trailer, which is pulled by a car. Today a large number of different products and designs of trailers can be found on the market. The difference in shaping of trailers depends on tradition and experience. There are no detailed directions on the demands for shaping of horse trailers today. The literature review contains a market analysis of both Swedish and imported horse trailers.

The European Union is a 60 year long collaboration between the European countries. It was born from the intention to ease trade and thereby reassure peace. Within the 60 years EU has functioned it has developed and expanded further. In 1952 it evolved around the trade of coal and steel between six countries, today it includes 27 nations and oversees a large number of topics such as foreign affairs, a common currency and regional politics. EU has grown at several times, the latest expansion was the largest where 12 new countries became members. The unions of countries that only 60 years ago were at different sides of a world war can be considered an accomplishment.
