The purpose of this paper is to survey the textile based proto-industrialism in Sweden in the middle of the 19th century. This case study is founded upon Anders Hansson?s pre-industrial textile production at the estate of Mölneby, Östra Frölunda in the rural district of Kind in the province of Västra Götaland.Account books from the year 1853 related to Anders Hansson?s wool fabric manufacturing have been looked into and categorized using a quantitative research method. The research has also been supplemented with a number of interviews.The result of the survey shows that Anders Hansson?s business activities fit into Mendel?s theory of proto-industrialists at a practice level.By collaborating with a merchant in Gothenburg the fabrics were traded in unknown markets, as well as in more familiar neighbouring districts.

This study was made on former agricultural areas that had been planted with spruce or pine, in the county of Västerbotten. The goal of the project was to investigate suspected deficiency of boron in these areas. Several objects have been reported for possible deficiency and some of these have the characteristic symptoms of boron-deficiency. The hypotheses are that 1) Boron deficiency is present at several of the investigated objects. 2) Planting of forest on cultivated postglacial sediments leads to a successive podzolisation with a decreasing content of organic matter in the mineral soil, due to decomposition, and a decreasing pH in the soil, even on locations that have been added lime. To be able to confirm or reject the hypotheses a number of tests were performed.

Osteoporos är en sjukdom som under de senaste decennierna ökat. I Sverige inträffar det cirka 70 000 osteoporosrelaterade benbrott varje år. Den största gruppen som drabbas är kvinnor efter menopaus. Syftet var att belysa faktorer som är av betydelse för prevention av osteoporos och osteoporosrelaterade frakturer hos postmenopausala kvinnor. Metoden var en systematisk litteraturstudie bestående av 10 vetenskapliga artiklar varav 9 baserade på kvantitativ och en på kvalitativ forskning.

In a column experiment the effect of three different biochars on nitrous gas emissions, nitrogenretention and water filled pore space (WFPS) were studied in a Swedish sandy soil, classified as aCryopsamment. Ammonium retention was positively correlated, while KCl-extractable ammoniumwas negatively correlated, with the specific area of the biochars. The question was raised whether thenegative correlation between extractable ammonium and biochar specific area reflects the amount ofammonium present in the soil or its extractability from the biochar, and whether methods forextracting soil mineral nitrogen, like KCl-extractions, have to be modified for application on biocharamended soils. There was a tendency of increased nitrate retention and KCl-extractable nitrate withbiochar and KCl-extractable nitrate was positively correlated with the specific area of the biochar. pHwas higher for all biochars compared with control, although the differences were not significant, andWFPS was lowered by biochar addition, significantly in one case.

Bovine milk is an excellent source of bioactive peptides. The bioactive peptides are in an inactive state in the protein and are released during enzymatic activity, e.g. during cheese ripening. Specific properties of bioactive peptides from ripened cheese has been reported, e.g. antihypertensive, antioxidative, antimicrobial, immunomodulatory and mineral binding.

Samflotationskretsen i anrikningsverket vid Aitikgruvan består av fyra parallella linjer med nio flotationsapparater i varje serie. Fraktionsanalyser på anrikningssanden från flotationen har visat att förlusterna av koppar i stor utsträckning finns i de grova partikelstorleksklasserna. Scavengerceller av typ OK-38 (Outokumpu 38 kubikmeter) i en av serierna, 800-serien, hade modifierats för att förbättra suspenderingen och därmed floteringen av grova partiklar. Tack vare modifikationerna hade suspendering av materialet i flotationscellerna blivit bättre vilket konstaterades genom att mäta andelen fast material på olika nivåer i cellerna, men man hade inte kunnat iaktta något förhöjt utbyte av koppar. Syftet med projektet har varit att det skulle leda fram till vägledning över hur hydrodynamiken påverkar flotationen och ge rekommendationer för hur apparaterna skall utrustas samt att företaget vill ha erfarenheter av inköpta provtagarnas metodik.

Examensarbetet är utfört på smältverket Rönnskärsverken på uppdrag av Boliden Mineral AB. Kopparhyttan är en elektrisk smältugn för smältning av kopparslig och sekundära material i form av askor, fragmenterat skrot, krossad skärsten, slagger och slam. Beroende på hur det ingående materialet varierar kommer smältans kemiska sammansättning att variera. Variationerna i smältans kemiska sammansättning medför också att de fysikaliska egenskaperna hos smältan varierar och därmed också värmeöverföringen mellan smälta och tapputrustning. En hög värmelast på tapputrustningen medför ett ökat slitage på tapputrustningen och därför behövs en förståelse för de bakomliggande orsakerna för att förebygga och om möjligt undvika detta.De genomförda analyserna visar på att en hög värmelast på tapputrustningen framförallt är kopplad till kopparhalten.

This bachelor thesis project has been executed at Outotec Sweden AB in Skellefteå. Outotecs main business focus is selling mineral and metal processing technologies. A rest product from the metal process is particle-polluted gas and cyclone designs are today the most commonly used abatement device for particle control. A cyclone provides a simple design with high efficiency particle percolation by using air streams.The purpose of this work is to reduce the time it takes create new cyclone designs in Outotecs projects. An extensive construction work is needed for every new cyclone order due to new designs.

An increasing demand for wood products in China has resulted in large areas invested in fast-growing tree plantations of eucalyptus. Eucalyptus plantations are often associated with an intensive management including fertilization. By understanding the effects of fertilization and where in the ecosystem nutrients are accumulated a more sustainable forest management could be achieved. In this study, a nutrient budget including all biomass and soil components was created for Eucalyptus urophylla. The examined nutrients were nitrogen, phosphorus and potassium.

In the collections of the Vasa Museum, 100 leather objects have exhibited salt precipitations. The objects, that have previously been impregnated with PEG, have become deteriorated and fragmented due to the precipitations. During a previously conducted study it was established that the precipitations consisted of iron and sulphur. However, it was not established whether they occurred in the leather?s inner structure and no treatment plan was developed.

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).

This work is about getting to know tufting as a technique and to design tufted products for home furnishing.It all began in Finland, where during springtime 2004, I got in contact with the technique oftufting for the first time. A very pleasant meeting that resulted in two carpets and a longing to continueand learn more. It was then that an idea for my final project started to take form. My wish was to designtufted ?floor jewelleries? and cushions.I made a base for my project during a design project in autumn 2004.

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.
