Guld i Sverige - Från urtid till nutid

The Earth and everything else in the universe was created in the Big Bang around 14 billion years ago. A point with tremendous density and mass began to expand and more and more atoms began to form. From the first and lightest like hydrogen and helium to heavier atoms such as iron and eventually gold. The formation of the Earth occurred about 4.6 billion years ago and so the first gold atoms were concentrated only here. It is however believed that much later in Earth's history an extra supply of gold occurred thanks to massive meteorite bombardments.

Information för beslutsunderlag i trafiksituationer inom sjöfarten - hur hanterar vi den?

I detta examensarbete har jag undersökt förmågan hos nautiker att ta fram och tillgodogöra sig information från radar och ARPA för sitt beslutsunderlag i trafiksituationer. Syftet var att få förståelse i om fartygsbefäl haft svårigheter att få fram denna mycket relevanta information. Detta gjordes med hjälp av förstudier i form av intervjuer med erfarna fartygsbefäl. Dessa intervjuer gav kriterier som möjliggjorde analyseringen av 13 olycksfallsrapporter, vilket utgjorde litteraturstudien. Dessa rapporter var författade av engelska Department of Transport, Marine Investigation Branch(MAIB), Statenshaverikommission(SHK) och  Sjöfartsverkets rapportserie(SjöfR).

Utveckling av en ny typ av båtstål åt Rupert Marine AB

Rupert Marine tillverkar och säljer RIB-båtar, som är små snabba båtar med riktigt, stelt, skrov och uppblåsbara tuber runt skrovkanten. Bakgrunden till denna masteruppsats är att det ofta finns stora brister i förarmiljön och förarplatsernas utformning på båtar. Företaget upplever att man har en lucka i sitt utbud av stolar. Det saknas en komfortabel och multifunktionell stol för fritidsanvändare. Det finns företag som tillverkar stolar separat för mindre snabba båtar.

Ståndort och växtval på takterrasser

In the country of Jordan, egg production is very important economically, but several bacte-ria are involved in food borne diseases transmitted from eggs or other poultry products. The most important are Salmonella spp., Campylobacter jejuni and Escherichia coli. In Jordan two different housing systems are used for hens in large scale egg production; con-ventional cages and litter floor systems. Eggs from four different farms were analysed and compared to see if a difference could be found regarding the presence of pathogenic bacte-ria on the egg surfaces between these two systems. Total number of aerobic bacteria was analysed, the presence of Salmonella spp., C.

Det svenska områdesskyddet : Ett samspel mellan diskurs och institutioner

Sweden has had laws protecting nature for about a hundred years. In this paper the views of nature and the values that serve as a rationale for protective measures are analyzed as results of a social process characterized by the dialectic relationship between institutions and discourse. Critical discourse analysis (CDA) is used to study this relationship and the discursive practices used by institutions, which reproduce or reshape views of nature that define the relationship between society and nature. Institutional design contributes to shaping discourse in the field of nature protection, while being originally shaped by discourse. In Sweden, the national park is an institution that reproduces a view of nature as the wild and untamed opposite of society, and the natural reserves reproduce a view of nature as holder of a multi-faceted set of values intertwined with society.

Kloridhalter i gran utmed en depositionsgradient för havssalter :

The knowledge of the chloride content and its fluxes and patterns in trees is insufficient. Increased knowledge would be desirable, one of many reasons is to be able to more efficiently meet the problems that the substance causes in the pulp industry. The purpose of this study was to examine and describe the chloride concentration of Norwegian spruce (Picea abies L. Karst.) in the south of Sweden. Furthermore the aim was to be able to predict chloride concentration from readily measurable site factors.

Samrådsunderlag för Lysekilsprojektet : Forskning och utveckling av vågkraft

The aim of this research is to find out what environmental impact a wave power park has on the Swedish west coast by creating a consultation paper (?Samrådsunderlag?) for the Lysekilproject at Uppsala University. To highlight the complexity of the problem a system analytic approach was used and illustrated by a Causal Loop Diagram.The overall assessment of the Lysekilprojects wave power park at the Swedish west coast is that it will have a low impact on the environment. This is due to the relative small size of the wave power park and some technical solutions made with the environmental aspect in mind. Artificial reefs and a sanctuary for marine species are effects created by the wave power park and in the longer term the impact will give access to an untapped source of renewable energy, wave energy.

Underlag för framtagning av målningslina : Hantering och layout

Seabased Industry AB develops system for extracting electrical energy from ocean waves with a Wave Energy Converter (WEC). The components is bought from subcontractors and then assembled into wave energy converters, buoys and marine substations by Seabased. In the future Seabased will produce more of the components themselves to reduce costs and to have better control over tolerances. The production line will also include the painting of the WECs and substations, which is performed in a painting line.The purpose of this thesis work is to study what is required to build a painting line, regarding the types of stations, transporting types and the space needed. This will result in layouts for the painting line.To receive the necessary information about production theory and corrosion and surface treatment, literature concerning this area has been studied.

Hjärtfrekvens och kortisolkoncentration hos valpar under olika typer av valptest :

The aim of this study was to find possible relations between behaviour and physiology for puppies during different parts of a puppy test. This work deals mainly with the physiological part of the study. Thirtysix puppies, från five litters, were tested in a behaviour test where heart rate was measured and saliva samples were collected before and after each part in the test. Saliva and urine samples were analyzed for corisol concentration as an indicatior of stress. The tests were performed during two consecutive days in the breeders' home when the puppies were seven weeks old. In addition, heart rate and cortisol levels were also measured in the bitch since we were interested in finding out if there were any relations between physiological levels in bitches and puppies.

Förekomst av Giardia i symtomfria valpkullar :

The flagellate Giardia intestinalis has been known to cause diarrhea in both man and dog. Results from epidemiological studies have indicated that transmission of the parasite from dog to man is plausible even though that route of infection has yet to be shown. Several international studies have shown that the parasite frequently occurs in asymptomatic dogs. In Sweden the prevalence of Giardia in healthy dogs is not known though. In this study, faecal samples were collected at two separate occasions from 21 litters and 21 bitches showing no symptoms from the gastrointestinal tract. The samples from each litter were pooled but the samples from the bitches were analyzed individually.

Valbara kurser : En enkätstudie om valbara kurser för sjöingenjörsstudenter vid Sjöfartshögskolan i Kalmar

På ingenjörsutbildningar får studenter fördjupa sina kunskaper i programmets senare del i form av specialinriktningar eller valbara kurser. Detta är något som inte är tillgängligt för studenter som läser till sjöingenjör vid Sjöfartshögskolan i Kalmar men något som infördes på sjöingenjörsutbildningen vid Chalmers Tekniska Högskola 2009. Studiens syfte är att undersöka intresset för valbara kurser på 7,5 högskolepoäng (hp) vardera för sjöingenjörsstudenter vid Sjöfartshögskolan i Kalmar. En enkätstudie svarade på frågorna om vilka ämnesområden som var av intresse, hur många kurser eleven ville läsa, när under utbildningen önskas kursen läsas, om intresset för valbara kurser saknas och i så fall varför. Resultatet av undersökningen visade att de ämnesområden som är av störst intresse för studenterna på grundnivå är offshore/oljerigg och landkurser.

Prevalence of congenital defects in Swedish Hampshire, Landrace and Yorkshire pig breeds and opinions on their prevalence in Swedish commercial herds

This study concerns congenital defects in pigs; umbilical and scrotal hernia, cryptorchidism, kyphosis, splay legs, anal atresia, intersexuality and congenital tremor. The aim was to describe and estimate the prevalence of these defects and estimate the heritability for the most frequent defects, scrotal hernia and cryptorchidism in purebred Swedish Hampshire, Landrace and Yorkshire populations. Furthermore, information and opinions from herdsmen in commercial herds was collected and analysed. A low proportion of congenital defect pigs is of importance both from animal welfare and economic point of view. The accuracy of registration of the presence of defects in the litters has a decisive role for the ability to select against these defects.

Nordic Marine Sauna AB has, since 2005, designed, manufactured and sold floating saunas. Theproduct are characterised by a well thought thru and appealing design and its high quality. Thecompany is now intending to open a new business area by starting a subsidiary, NordicSubmarine Sauna AB, which will design submerged saunas. The expected customers are leisureand conference centres as well as customers that seek an experience out of the ordinary.Due to the products technical complexity a master thesis was adverted. The task was to do aninvestigation whether such a product is technically viable.The job involved research of existing products and constructions material as well as designingthe product with CAD and FEM-programs.

Automatiserad laddning och plundring mellan magasin

This thesis has been carried out within the bachelor program for mechanical engineering at Karlstad University in collaboration with BAE Systems in Karlskoga. The purpose with this work was to design a mechanism and associated parts for loading and unloading of shots between primary and secondary magazine in BAE's new 40mm's ship gun.Parts designed or redesigned among other things a transfer mechanism for shot at loading and unloading, well as a hatch mechanism which makes the shots do not fall out of the primary magazine when making separate use. Various important details have been designed to maintain a good functionality of the mechanism.The construction work has mainly been carried out in the CAD software Solid Edge and its associated FEM module. The construction work has also been carried out on rough calculations for constructed details in order to ensure that they meet the stringent requirements of military use in tough marine environment. Two of the most critical parts of the structure where analyzed with the FEM module for estimating the stresses in the material at the applied load.The final design, which is a result of the thesis, meets the requirement specification and the set targets.

Statlig sjöfart för maritim säkerhet : och hur ser Försvarsmaktens roll ut?

Den statliga sjöfarten idag är ett område med många inblandade myndigheter och en oklar uppgiftsfördelning. Det är även svårt att se hur väl organiseringen av den statliga sjöfarten är uppbyggd för att klara en kris eller ett krig. Syftet med uppsatsen är att undersöka hur effektiv den statliga sjöfarten är vid en kris, hur väl kraven för maritim säkerhet uppfylls och hur försvarsmaktens roll i den statliga sjöfartenI formen av en fallstudie med en teoretiskt deduktiv ansats och en kvalitativ textanalys appliceras Graham Allisons organisationsteori och teori om maritim säkerhet på den statliga sjöfarten. Empirin är i form av förordningar, instruktioner och reglerbrev som är ställda på respektive myndighet.Undersökningen visar att dagens organisering av den statliga sjöfarten inte är optimal för att verka vid en kris och kraven för maritim säkerhet uppfylls, men förbättringspunkter föreligger. En slutsats är att en närmare samverkan mellan myndigheterna skulle lösa många av de problem som idag existerar.
