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.

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.

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.

Jerlemar, M & Nordström, J., Patienters upplevelser av att leva med trycksår. En litteraturstudie. Examensarbete i omvårdnad, 15 högskolepoäng. Malmö högskola: Hälsa och samhälle, Utbildningsområde omvårdnad 2011. Bakgrund: Trycksår är ett vanligt förekommande sjukdomstillstånd som drabbar framförallt äldre och rörelsehindrade. Trycksår kan medföra fysiska och psykiska komplikationer hos den drabbade.

In search of Umbilicaria subglabra In Sweden Umbilicaria subglabra has its only known occurrence in Lybergsgnupens nature reserve in the county of Dalarna where it has been found only once in 1936. It was found on the east-facing rock spur, approximately 650 meters above sea-level. The lichen is now red-listed as Regionally Extinct (RE) in Sweden. The aim of this study was find U. subglabra.

Sweden has been a member of the European Union since 1995 and the power of the organisation to make decisions has increased over the years in a rate which hasn?t been followed by an equally increase in democratization. This is partly due to the lack of participation in the decision making process and at the national level the citizens don?t possess enough channels to compensate the loss of influence. To solve this democratic dilemma, more and more countries are turning to the referendum.

Bakgrund: En kombination av olika riskfaktorer och ett yttre tryck bidrar till att patienter drabbas av trycksår. Sjuksköterskor i samarbete med undersköterskor ansvarar för att förhindra risken för trycksår hos patienter. Tidigare studie påvisar att femton procent av inneliggande patienter på sjukhus drabbas av trycksår. Syfte: Syftet med studien är att belysa varför patienter får trycksår trots att sjuksköterskan i samarbete med undersköterskan bör ha kunskaper för att förebygga vårdrelaterade trycksår. Metod: Författarna använder sig av metoden allmän litteraturöversikt.

Syftet med denna litteraturstudie var att undersöka om nutritionstillskott, tryckavlastning och typ av förband har någon påvisad effekt på läkningen av trycksår. Litteraturstudien grundar sig på Goodmans systematiska tillvägagångssätt. Litteratursökningen gjordes i CINAHL, PubMed och The Cochrane Library samt att artiklar som inte var tillgängliga i fulltext via någon av databaserna söktes via Samsök. Granskning och kvalitetsbedömning av artiklarna gjordes individuellt utav författarna oberoende av varandra utefter ett modifierat granskningsprotokoll. Elva artiklar av varierande kvalitet inkluderades i litteraturstudien.

Vattenfall Heat Uppsala runs the waste incineration plant in Uppsala, which produces district heating, process steam, district cooling and electricity. Vattenfall Heat Uppsala has decided to introduce an energy management system with the aim to increase the energy efficiency of the plant. The basis in such a system is to make an energy mapping.In this thesis an energy mapping has been performed at the waste incineration plant with the aim to identify and determine the size of energy flows. The investigated energy flows are used fuel, produced and used steam, produced district heating and cooling. Also the use of electricity to run the processes has been investigated.

Syftet med denna litteraturstudie var att beskriva hur sjuksköterskor arbetar med preventiva åtgärder vid trycksårs uppkomst samt vilka omvårdnadsåtgärder som ges till patienter som utvecklat trycksår. Vetenskapliga artiklar söktes i databaserna Medline via Pubmed och Cinahl med sökorden nursing, pressure ulcer, prevention, treatment, therapy, intervention. Endast artiklar från år 2003- mars 2008 användes i studien. Både kvantitativa och kvalitativa artiklar användes, dessa artiklar granskades utifrån två modifierade granskningsprotokoll. Resultatet påvisade variationer av dessa preventiva insatser som sjuksköterskor använde sig av.
