To reduce emissions of carbon dioxide (CO2) Carbon Capture and Storage (CCS) technologieshave been developed. Chemical Looping Combustion (CLC) is a CO2 capture technologywith the CCS framework, and at Chalmers University of Technology in Gothenburg,Sweden, a 100 kW chemical looping combustor has been built.This project aimed to investigate to what degree air can replace helium as the uidizinggas for uid dynamical studies in a CLC cold ow model of the above mentioned 100 kWfacility. Experiments were performed using air and helium separately as uidizing gas andpressure data were obtained, which formed the basis for the comparison. The project alsoaimed to investigate uid dynamics in the uidized bed and study when the risk of sluggingoccuring was greatest. The results were presented in the form of figures and tables dividedinto pressure, concentration and standard deviation of the pressure.The results obtained showed that air as uidizing gas did not create the same uid dynamicsas helium over the entire fuel reactor.

This study aims to investigate how federations manage to balance the economies of scale through collaboration and autonomy. This is done through a case study on Länsförsäkringar. The lack of modern research on federations makes the federative structure an interesting field of study. Previous research has shown a general perception that an increased pressure on efficiency and economies of scale creates a stronger common unit that eventually creates an imbalance in the federation. It is therefore interesting to look at the balance, which exists between the member units and the common unit of a federation.

The purpose of this Master thesis is to examine whether the term elasticity is relevant and functional to apply to public library organisations. Another aim of the thesis is to relate the term elasticity to public library organisations in a network society. Sociologist Manuel Castells provide the theoretical framework on the network society. Three investigations (meant to complement each other) in two Swedish public libraries seek to give answers to these questions.To be able to examine which areas of public library activity are elastic, I make a rough definition of what public library organisations consist of ? nine activity fields are identified using IFLA?s guidelines in combination with Swedish law of public libraries.

The primary function of a mixer is to keep a fluid in constant motion. All mixing applicationsrequire varying degrees of small-scale turbulence and bulk flow. The performance of asubmersible mixer is measured by the thrust that it produces, while the strength of the bulkflow is dependent on the total amount of installed thrust.In a mixer, the fluid quickly flows past the propeller, and as a result, the current is mainlyaxial. The fluid will also obtain a rotating velocity, or a swirl, though this is significantly lessthan that of the propeller. During the process, the total amount of energy increases in the formof static pressure and kinetic energy.

Den bullerreducerande beläggnigen har en porös struktur som förbättrar dräneringen och reducerar buller vid källan men egenskaperna orsakar ett snabbt slitage och portäppning. Detta medför att beläggningen måste omläggas och rengöras oftare än en konventionell beläggning som t.ex. ABS 16. Kritiken mot den bullerreducerande beläggningen riktar sig på de höga drift- och underhållskostnaderna, detta gör att många väghållaren satsar på bullerskärm som bulleråtgärd.  Syftet med arbetet är att jämföra bullerreducerande beläggning med bullerskärm, för att reda på vilken bulleråtgärd är mer kostnadseffektivt under 20 år. Ett teoriavsnitt kommer att förklara och beskriva på ett tekniskt sätt: väg, ljud och buller, bullerskärm och bullerreducerande beläggningar.Kostnadsjämförelsen mellan bulleråtgärderna omfattar investering, drift och underhåll.

In 1993 the internal market within the European Union was formed and ensured free movement of goods, services, capital and people. This led to the removal of trade barriers between members of the European Union. When opening up for competition, price differences between countries decreased and more jobs were created. A single currency was introduced by eleven countries in 1999 with the goal of reducing transaction costs, eliminating exchange rate risk and to further simplify trade. In 2001 Greece joined the collaboration and introduced the euro.

Habia Teknofluor AB makes parts of PTFE. With their process they reaches a pressure of 250bar at maximum. For their parts to improve they need to reach 400bar at least. We will give suggestions that can solve their problem. All our suggestions is described in the report with a conclusion.

The aim of this study was to investigate the intraoperative surgical stress response in dogs undergoing ovariohysterectomy and to compare acepromazine and medetomidine as premedications. 15 dogs diagnosed with pyometra were used in this study. Blood pressure and heart rate were used as parameters to measure surgical stress response. The surgery was divided into four phases. Phase 0 was the period 10 minutes before the skin incision, phase 1 was skin incision and opening of abdomen, phase 2 was manipulation of uterine horns, ligation and transection of mesovarium and phase 3 was ligation of cervix, removal of organs and closing the abdomen. The results showed that phase 2 was the most intense phase of surgical stress, regardless of which premedication the dogs received. When acepromazine and medetomidine were compared the results showed that within phase 3, all dogs that were given medetomidine had higher blood pressure compared to dogs that were given acepromazine. The dogs that were given acepromazine had higher heart rate than the dogs that were given medetomidine in phase 0, phase 2 and phase 3. .

Increased understanding of the mechanisms that operate in conjunction with the welding of metal surfaces may help to improve existing manufacturing processes, and to enable new products and combinations of materials. The purpose of the project has therefore been to acquire a deeper understanding of what is happening in the bond for steel and for the factors that form the basis for a bond to develop between metals in the production of laminates by pressing. The merge has been done by pressing and the surfaces after the experiments have been studied in detail in the scanning electron microscope (SEM), energy dispersive X-ray spectroscopy (EDX) and with interferenceprofilometry in Wyko, to provide a greater understanding of the mechanisms that influence the bonding in the interface between metals. The project was limited to contain the materials Docol 1000, HyTens 1200, Aluminum AA3003 and a commercial steel. The parameters varied in the experiments to study their influence closer are temperature, pressure, heat treatment and pretreatment. This has been implemented by pressing with varying temperature and pressure.
