The county administration asked LKAB to make an inventory of possibly contaminated sites caused by their mining activity. The inventory should be performed according to the MIFO model, a method from SEPA which is used to assess a contaminated site. The first phase involves collection of information through interviews and site inspections and in phase 2 a general survey with field sampling is conducted.LKAB started the work with the first phase of the survey during 2003. During this project the information collected in Phase 1 was evaluated and 16 of the sites were chosen to proceed to MIFO Phase 2 (six sites in Kiruna, and 5 sites respectively in Svappavaara and Malmberget). The sampling of these 16 sites was performed during week 27 2004.

Corn is an important food and feed crop in the world, in Sweden it?s up till now grown on limited acreages mainly for silage. But I think it can get more important if you can grow it also for grain, because it?s a good animal feed for example, for life stock-, pigsand poultry. On of corns advantage is that it can produce the same amount of dry matter as for example wheat, barley and rise but with 25% less water. I will examine if it possible to grow corn for grain production in the south of Sweden.

Background: Testosterone is the most important androgenic hormone in the male. Aging is closely associated with reduction of serum testosterone which can lead to reduced muscle mass, muscle strength, bone density, and depression. These symptoms may be counteracted by administration of testosterone. Objective: The purpose of this study was to examine the effects of hormone replacement in men with age-related testosterone deficiency. Method: We performed a systematic review using Randomised Controlled Trials (RCT).

Examensarbetet behandlar tekniker för sekundär öppning av storskaliga brytningsrum i Boliden Mineral AB:s underjordsgruva i Garpenberg: När längden på brytningsrummen överstiger ett visst värde måste brytningen indelas i två steg: där första halvan av rummets längd bryts och återfylls i första steget, varefter återstående av rummets längd bryts i ett andra steg. I inledningen av brytningens andra steg krävs en fri yta att kunna spränga den kvarvarande malmen mot - dels för att ge plats för berget att svälla i och dels för att fungera som fri yta för de av produktionssalvorna uppkomna stötvågorna att reflekteras mot. Den öppningsspalt som används idag åstadkoms genom borrning och sprängning med relativt tätt hålmönster. Idén till arbetet var att det bör gå att göra både kostnads- och tidsbesparingar genom att använda en alternativ metod till borrning och sprängning vid skapandet av öppningsspalten. Målet med arbetet var därför att hitta en teknik som uppfyller denna idé.

During the summer of 2005 a number of steer producers in Skåne, Sweden, found that their animals graded less favourable according to the EUROP carcass grading system when slaughtered, than ordinary. The aim with this project was to determine factors that affects the production result in steer production and to find the reason to the lower classification. The project was initiated by Anita Persson, LRF, Skåne and was preformed with supervision from Ingemar Olsson, SLU, and Jens Fjelkner, Skånesemin. Ten producers of dairy steers located in Skåne was chosen for this study. The producers were interviewed to collect information about their steer production with respect to their planning and results.

För att på skrivbordsnivå få möjlighet att planera framtida brytning i en gruva har det i dagsläget utvecklats ett antal olika mjukvaror som stödjer produktionsplanering för underjordsbrytning. I samband med att brytningen under jord förflyttas måste även ventilationskanaler förse fronterna med luft. Ventsim är ett program som är utvecklat för att simulera luftflöden i en underjordsanläggning. För att simuleringen ska bli trovärdig, krävs det att Ventsim-modellen kalibreras utifrån verkliga, uppmätta värden. För Kristinebergsgruvan blev en sådan modell uppritad för ett par år sedan.

This bachelor essay is divided into two parts, the first being a construction of a single-familyhouse and the second an in-depth study of five different isolation materials, analysed from anenergy perspective.The first part, the construction of the single-family house, has been created from knowledgeacquired during three years of studying at KTH Royal institute of Technology in Stockholm, inthe program Architecture and the Built Environment. The constructed house is a one-floorhouse of 137m2with façade plaster, situated in Borlänge, Sweden. The house has a wooden framewhich is built on a on sight cast concrete foundation, on the ground. The house?s roof is a gableroof, which has an angle of 24 degrees.

Boliden Mineral Ab's mine in Garpenberg, Dalarna is going through a massiveexpansion. The annual ore production is being increased from 1,4 million tons to 2,5million tons in less than two years period of time. Along this expansion thedepartment of mining techniques is administrating a project of optimizing the shortterm planning for the mining production. Garpenberg have since mid 90s storedinformation from all mining processes in a database.The information consists of time data from all the different activities required in themining process, for example charging, blasting, loading etc. The database also containstime data of delays that are affecting the production.

In the fluidized bed furnace at Rönnskärsverken, Skelleftehamn, sulphur-containing ore concentrates are roasted in order to remove about 50% of the sulphur in the incoming ore concentrate. This occurs in order to reach the goal of a matte containing 55% of copper in the following smelting process. At the same time as the ore concentrate is partially roasted pollutions as arsenic, antimony and bismuth are expelled. Earlier made thermodynamic calculations of equilibrium suggested that calcium and magnesium form stable compounds with arsenic and thereby inhibit expellation of arsenic in the fluidized bed furnace, an element that is undesired. The purpose of this thesis work was to gain knowledge of the mechanisms behind the formation of these stable arsenic compounds.

Hörneborg ligger på en udde i sjön Hörnsjön i Olofströms kommun i Blekinge län. En utgrävning av borgen gjordes 1997 för att fastställa funktion och ålder. 14C dateringar visade att borgen var byggd cirka 1030-1250 e.Kr. och förstördes genom brand någon gång mellan 1290 och 1420 e. Kr.

The dog is unique in the way that the adult weight can vary 100 folds between the different breeds. Despite this, most of the breeds reach adult size before two years of age. For the large-breed dogs this means a very rapid growth when some of them can have a weight gain of up to 150 times their birth weight. The most rapid growth occurs when the puppies are between three to six months old and that kind of rapid growth during such a short period of time makes these large-breed puppies very sensitive to deficits and excesses of energy, nutrients and minerals. Some examples can be excess of energy, excess or deficit of minerals such as calcium and phosphorus or deficits of protein. The rapid growth can also make the large-breed puppies predisposed to some diseases affecting the skeletal and joints.

Phosphorus (P) is an essential nutrient but a surplus could lead to eutrophication. Furthermore, the minerals used to produce the mineral phosphate is a non renewable resource. There are in other words several reasons to reduce the leakage of P and the agriculture is one important area to attend. The aim of this work has been to investigate if carbon-rich arable soils content contain more P than arable soils with low carbon content. Moreover it has been calculated if the carbon-rich soils could pose a risk of P leakage by comparing their delivery of P with the plant uptake. The work has consisted of compiling the results from former gathered and analysed soil samples of 130 Swedish arable soils. The fractions of P considered are water soluble P (Pw), ammonium lactate-extractable P (P-AL), hydrochloric acid-soluble P (P-HCl), organic ammonium lactate-extractable P (Porg-AL) and inorganic ammonium lactate-extractable P (Porg-HCl).

Biogas is a renewable energy source that is produced by anaerobic digestion of organic mate-rial. In Sweden, biogas predominately comes from sewage water sludge and landfills or from organic waste of households and industries. Small scale digestion plants at farms are espe-cially expected to contribute to increased biogas production in the future. Biogas can be ob-tained directly in it?s raw form and used as fuel in a combustion chamber.
