In industry applications, such as power supply plants, the issue of interaction between fluid and structure is always presented. More precisely, the fluid flow affects the structure by applying force(s) on it and vice versa. As a result, the structure can move (vibrate) or deform. A good understanding of this problem can help to design the system in term of safety, stability and efficiency.This project aims to optimize and test the Unicorn FSI solver from the FEniCS project [1] to simulate the interaction of fluid and structure in an experiment, which was carried out at Vattenfall Research and Development. The target is to improve the Unicorn FSI solver to cope with a real industrial problem.

Background and aims: The population of older people in our society is increasing. Agerelated changes in the skin results in a diminished perception of pain and pressure and a decreased microcirculation in the skin affects its ability to adapt to injury. Occurrence of pressure sore on geriatrikal clinics are 5-10%, witch means that between five and ten thousand patients gets daily treat for pressure sores. When the patient gets a pressure sore the need for help increases. A common apprehension is that if the patient?s affects with pressure sores it?s because of deficiency in care.

Background: One of the healthcare tasks is to inform and support patients. Information and support is very important for the management of the disease in patients with psoriasis. Healthcare often focuses on the medical aspects and can easily forget about the individual behind the disease.Aim: To explore what kind of information and support patients with psoriasis receive and need to manage their skin disease.Method: Quantitative study with descriptive design and qualitative elements by analysis of the questionnaire with open questions. The study included 22 participants.Findings: The majority of participants responded that they had received information about various therapies, medications and generally about psoriasis. The information participants most often responded they needed, was essentially continuous information and updates on treatments and knowledge about psoriasis according to medical science.

Platelets are important for the healing of damaged blood vessels since they have an importantpart to play in the coagulation process. At the same time, the blood must be kept fluid and notcoagulate at the wrong time. Therefore there are factors that effect the aggregation of plateletsin a positive or a negative way.Previous investigations have shown that platelets during stirring conditions produce reactiveoxygen species (ROS) that weaken the inhibiting effect of nitric oxides (NO) on platelets andthat the drug Dexamethasone (Dex) can reduce the ROS-production.The aim of this project was to investigate if glucocorticoids, in this case Dexamethasone,could restore the inhibiting effect of NO on platelets and if there was any decrease in ROS-production.The result of the ROS-measurements showed a great variance and it was difficult to draw anyconclusions from them, but a clear decrease in ROS, as previous reported, was not shown. In the aggregation experiments the inhibiting effect of NO was observed through the drug S-nitroso-N-acetylpenicillamine (SNAP), a NO-donator.From the aggregation experiments, the result seemed to be that SNAP during longerincubation time lost its inhibiting effect, probably because the cells become desensitized.With superoxid dismutase (SOD), the effect of SNAP increased, both in the experiment withlonger and shorter incubation times. Dex seemed to reinforce the aggregation in relation toboth SOD and SNAP.

Consumers today leave a fragment of information when they pay with their debit and credit cards. The aim of our work is to investigate ways to design a concept of a system in which digitally stored information that today is fragmented among several different holders, can be assembled into a system and made available to consumers. In our study of how a system for financial flow of information should be designed, we intend to study the present situation and the attempts made to alter it into a more informative reality. We intend to investigate the flow of information when a consumer pays by card, and the possible solutions regarding the design and transportation of digital receipts. A majority of the information of our digital consumption is today handled digitally.

Transdermal drug delivery, besides painfulinjections with syringes, has long been associatedwith small size particle pharmaceuticals, which candiffuse through the skin. This method of drugadministration has only been applicable on a smallnumber of drugs, where active molecules are smalland delivery time should or can be long.Other drug delivery options are oral administrationand injection with hypodermic needles (ordinaryhospital syringes). In oral administration thestomach and liver tend to dissolve the drug and theeffect becomes more difficult to anticipate, anddrug delivery rates difficult to control. Hypodermicneedles are used as a mean of drug injectiondirectly into the bloodstream. This method ispainful and risks infection due to tissue damageand skin penetration.One way to get a painless non-damaging techniquewith high delivery rate that still can delivery largemolecules is to manufacture an array of microscopichollow needles and equip them with a pumping unitthat delivers the correct amount of drugs.This thesis shows the technique and possibility ofmanufacture micromachined needles using low costtechniques of Ion Track Technology (radiation ofheavy ions creates porous materials), electrolessdeposition (non-current activated wet chemistrymethod of depositing metal) and electroplating.

An information audit identifies, among other things, organizations information resources, the information flow and the needs of the information users. The purpose of this masters thesis was to describe the management of information within a local unit of Borås municipality by putting an information audit-method in practice. The focus was on three issues: What information needs could be seen in the organization? How does the information flow through the organization? How does Sugan Henczels seven-stage model serve as a tool to map the management of information within the local unit? The study only described the situation at a certain time at the chosen organization. The seven-stage information audit model was revised and adjusted to the studied organization by only carrying out four of the seven steps: Planning, Data collection, Data analysis and Data evaluation.

Syftet med denna studie var att undersöka unga idrottares upplevelser i en topprestation.Studiens frågeställningar var:·        Vilka upplevelser har unga idrottare i en topprestation?·        Upplever unga idrottare flow i en topprestation?·        Vilka faktorer ligger bakom en topprestation hos unga idrottare? Utifrån syfte och frågeställningar valdes mätinstrumentet Flow State Scale-2 (FSS-2). FSS-2 består av ett påståendeformulär som mäter den totala upplevelsen av flow samt var och en av de nio dimensionerna av flow.Kontakt togs via telefon och mail med ansvariga tränare vid idrottsgymnasier för att finna unga idrottare med ett tydligt minne av en topprestation. Undersökningsgruppen blev 51 stycken unga idrottare, män och kvinnor i åldrarna16-20 år som utövat fotboll, ishockey eller orientering på elitnivå.Litteratursökning gjordes i bibliotekskatalogen tillhörande Umeå Universitet. Den funna relevanta litteraturen och artiklarna har legat till grund för denna studies bakgrundsdel. Påståendeformuläret FSS-2 visar att undersökningspersonerna, i sin topprestation, hade en stark upplevelse av inre tillfredsställelse, tydliga mål, koncentration på uppgiften, känsla av kontroll och balans mellan skicklighet och utmaning.

Findus Sverige AB, referred to asFindus from now on, harvests peas during a period ofaround 50 days during the summer. The harvest generates about 30 000 tonnes of peas which gives around 40 000 pallets to distribute to the warehouses which Findus uses for final storage. Three hours after the peas are picked in the fields, they have to be frozen to keep their good taste and quality. Because of this the pallets are marked with a preliminary label with quality classification of the content. The Findus quality department then has one day to determine the correct quality of each pallet.

Inledning: Sjukvården är beroende av frivilliga bloddonatorer. Det behövs alltid fler bloddonatorer då vi med dagens sjukvård kan utföra alltmer avancerad kirurgi samt rädda och hjälpa allt fler sjuka samt skadade, med hjälp av blod från frivilliga donatorer.Syfte: Syftet var att undersöka vilka skäl som anges till att inte donera blod, samt undersöka om viljan att ge blod skiljer sig beroende på kön, ålder och om man har yrkes- eller studieanknytning till sjukvård. Syftet var också att undersöka vilka faktorer potentiella blodgivare anger som motiverande till att donera blod.Metod: Denna uppsats baseras på en kvantitativ tvärsnittsstudie, bestående av en webbenkät som delats av författarnas på det sociala mediet Facebook. Enkäten vände sig till personer som enligt blodcentralens kriterier får donera blod, totalt inkom 90 svar, med ett bortfall på totalt 11 personer. Enkäter analyserades sedan kvantitativt med hjälp av statistikprogrammet SPSS.Resultat: Studien visar att den vanligaste orsaken till att respondenten inte gått och donerat blod är att de tillfrågade har tänkt på det men att det inte blivit av.

In the digitized world many organizations experience a large flow of information. To sort and manage all the information can be difficult. Individuals may experience a phenomenon called ?Information Overload?, due to the fact that the information flow is too extensive. There are various reasons why individuals are affected by this phenomenon.

This essay is a case study carried out at Flow Systems Ltd that foremost aims to treat the internal marketing at the company. The aim with the essay is to analyze and evaluate Flows internal marketing in connection with a process of change and how this reflects the external marketing in relation to customers.The method that has been used is qualitative in the form of depth interviews carried out with management, employees and customers. This type of data was chosen since it is a good way of gathering more specific information regarding the informants preferences about the company. Among other things the results of the interviews showed internal marketing deficiencies, but that has not influenced the customers in a negative way. The conclusion was that the inferior internal marketing does not affect the cooperation and the communication between the company and its customers, however it has a big effect on the employees..

Concrete is a very common construction material. It´s characteristics are strength, durability and formablility. Superplasticizer is a common admixture, which changes the properties of concrete. Today (spring 2007) there are no certian mathematical methods to calculate the required percentage of this admixture needed to give the necessary set slump flow in the overall concrete recipe. Concrete batching companies must therefor experiment with different amount of superplasticizer in order to meet the specified slump and strength. The purpose og this report is to investigate if any mathematical relation can be established between the amount of superplasticizer used and the slump flow achieved. After carrying out some practical experiments using four different superplasticizers a direct relationship can be establish between the percentage of admixture used and the slump/flowability achieved. Unfortunatly at present due to the numerous variables, the calculation of mathematical formula can not be achieved..

Treatment wetlands been showed efficient for reducing pollutant in waste water. In Lajeado ? RS, Brazil the landfill has poor leachate water treatment. It is necessary to supplement the treatment plant because they need to reduce BOD, COD and nitrate of the water going to recipient. A subsurface flow wetland (SSF) can be a good choice.  In order to be able to design an efficient SSF it is important to understand how the grain sizes of a substrate affect the reducing of pollutants in waste water.
