Optimering av informationsinsamlingvid prototyptillverkning

This report discusses a method to detect divers in harbour environments usingpassive acoustic detection. The goal was to achieve as high detection as possiblewithout having too high false alarm rate. A short execution time was also desirable.By using the characteristic of an inhalation a band-pass filter was applied to the signalto improve the signal to noise ratio. After the filtering an energy estimation of thesignal was made. This energy estimation was later used in a frequency analysis, whichcould tell us if there were enough energy in the frequencies that correspond to adivers breathing frequency.

The impact of platelet storage time on transfusion results

Platelets are small fragments, but they are of crucial importance for the coagulation. The risk of spontaneous bleeding increases when the level of platelets falls below a thrombocyte particle concentration threshold value of 50 x 109/L. In those cases a platelet transfusion might be compulsory. Ongoing research tries to improve the quality of the platelets and to increase the safety of the method used. However, we still need to better understand which factors that affect how patients react upon platelet transfusion.

Över tröskeln : Ett nytt boendefenomen

Ett lågtröskelboende vänder sig till individer med missbruks- och boendeproblematik där intentionen är att erbjuda individen stöd i dennes alkoholproblematik samt en trygghet i boendet utan att ställa krav på nykterhet. Studiens syfte var att undersöka fenomenet: upplevelsen av att bo på ett lågtröskelboende utifrån ett brukarperspektiv, samt vad flytten till lågtröskelboendet har inneburit för de boendes livskvalitet. I analysen användes ett fenomenologiskt perspektiv med livsvärldsteorin som utgångspunkt. Resultatet visar studiens fenomen som existentiell samhörighet i alkoholmissbruk. Den delade alkohol- och boendeproblematiken gör att de boende upplever sig som jämlika med varandra, vilket också skapar en känsla av gemenskap och tillhörighet.

In-situ audiometri ? Vägen mot rätt förstärkning?

This study investigated whether in-situ audiometry, delivered via hearing aids, is a better option as a basis forprescribing hearing aid amplification, compared to conventional audiometry. By examining the real ear insertgain (REIG) in 29 ears (18 subjects), that had been fitted with a hearing aid programmed using both conventionalaudiometry and in-situ audiometry, the study looked at whether in-situ audiometry based prescription is closer tothe NAL NL1's fitting target than audiogram based prescription. The hearing aid Siemens Pure 7mi with speakerunit M was used on all participants. The results showed how in-situ audiometry based gain at certain frequenciesis more consistent with the target curve, especially at 1000, 1500, 2000 and 4000 Hz. It was not establishedwhether the findings of the study were statistically significant.

Går det att säkerställa ljudmiljön i en träningslokal? - en studie om ljudnivåövervakare på träningslokaler i Göteborg

In Sweden, exercise takes a great part in people?s lives. Health and a good conditioned body go hand in hand. Many Swedes exercise in groups, with aerobics or a similar form of workout at a training facility. A regular workout lasts for about an hour and is accompanied by music.

Afasi och luktförmåga

Att perceptuellt uppfatta och identifera lukter påverkas av en rad olika kortikala system och kognitva förmågor. Syftet med föreliggande studie var att undersöka huruvida personer med afasi har en luktförmåga som skiljer sig från normalpopulationen och ifall en afasiproblematik påverkar de faktorer som normalt involverar luktförmågan.         I studien medverkade tio försökspersoner, sex män och fyra kvinnor. Personerna hade varierande grad och typ av afasi och var mellan 42 och 76 år. Deltagarna delades in i åldersgrupper där två personer klassades som yngre och åtta som äldre. Samtliga testdeltagare genomförde två olika lukttest: Odor Threshold Test (OTT), och Swedish Odor Identification Test (SOIT).

Den som vet bäst vinner mest - Om information i butik och hur den används.

When in the process of buying a product based high effort behavior, the consumer needs information to decide on which product that best satisfies their need. There is a wide arrange of sources where this could be found. One of the most important, due to the great influence it has on consumer choice, is in-store communications. This is also one of the least developed sources. It is not uncommon that the only facts that can be acquired are found on product packaging and from contact with the store´s staff.

Fast driftställe enligt OECD:s modellavtal i ljuset av elektronisk handel

The purpose of this thesis is to examine whether the concept of permanent establishment, as defined in Article 5 of the OECD Model Tax Convention on Income and Capital, is applicable to electronic commerce and if so whether the current definition is able to appropriately deal with the challenges of electronic commerce.In 2003, the OECD added a new section to the Commentary on the Model Tax Convention on Article 5. The new section is a clarification on the application of the permanent establishment definition in electronic commerce.The current definition of permanent establishment in the Model Tax Convention relies on the physical presence of a foreign corporation as the threshold for source taxation. While the current definition, prima facie, might be applicable on electronic commerce, the highly mobile nature of electronic commerce might affect the current revenue distribution equilibrium between states..

Röhsska Backstage : är publika arbetsmetoder nästa steg framåt?

The Röhsska museum in Gothenburg has recently launched a new work method, Backstage, that is studied and paralleled to the museums permanent exhibition on Japanese design. In Backstage the museums routine work is executed in full view of the museums visitors in an exhibition area. The study has focused on the museums intentions and the visitors? interpretations in Backstage and Japanese design, as well as the staff?s experience of the work method?s public aspects. The study?s empirical material has been collected through interviews with the museum staff as well as observations and interviews with visitors in both Backstage and Japanese design.

Europa - en plats eller en idé? : En diskursanalys av den europeiska identitetens konstruktion

Today Europe is faced with an identity crisis concerning its borders. Turkey stands at the threshold for an EU-membership while the EU-Commission is trying to formulate what constitutes a European identity. This identity seeking process will determine the future not only for Turkey, but also for immigrants now living in Europe.In this thesis a discourse analysis, underpinned by socialconstructionist theory, is conducted to explore how the European identity has been constructed throughout history up until today. A starting point is that identity always is defined through a dialectical relationship to "otherness". Therefore the analysis is focused not only on what a European identity consists of but also what and who it excludes.

Årets gränsbelopp : Vem kan betraktas som ägare vid årets ingång

Being able to know how use the rules about how taxes works, allows a shareholder with qualified holding in a closely held company, to pay less taxes. When the owner of the share makes an agreement, which the ownership rights transfers later than the actual date for when legal contract is written. The question is therefore who can consider being the new owner at the beginning of the year and taking part of the benefits. Do the ownership rights transfer on the contract date or the date of access?When a buyer purchase a share during the year, he may not partake of any threshold amount, then the expected time is for those who are owners at the beginning of the year.

Investigation of tissue factor mRNA levels in human platelets using real-time PCR

Tissue factor (TF), a 47 kDa glycoprotein, is the initiator of the extrinsic pathway of blood coagulation and consequently of the upmost importance when damage to blood vessel occurs. The source of TF in circulation has been investigated. However, the source of TF is still not clear. One theory is that platelets express and increases the expression of TF after stimulation and the aim of our report was to investigate whether platelets really are a source for TF in circulation.Using specific primers for TF mRNA, platelets in plasma from healthy volunteers and from patients suffering from cardiac infarction were analyzed by using real-time polymerase chain reaction (PCR). Gel electrophoresis was performed after amplification of TF mRNA to verify the results.The samples were negative for TF when using real-time PCR and the few positive all had cycle threshold (Ct) values above 35.

Ett Radikalt Högerpopulistiskt Parti i Regeringen : En studie av FPÖ och dess valframgång i Österrike 1999

In this research paper I have interpreted and analysed how it is possible for a Radical Right Populist Party such as FPÖ (The Freedom Party) to obtain electoral success in the end of the last millennium. In 1999 they were elected into the national legislative parliament with 26.9% of the votes and participated in the Shüssel government from February 2000. I believe this is an extreme case study and my method is the so called Disciplined-configurative case study. I?ve conducted this study by using earlier published research and than dividing these old theories into to three analytical categories.

Dem matematiska problemlösningens roll i lärarens undervisning.

The purpose of this paper was to examine how clients on the unit for adults at Södemalms district administration (Stockholm, Sweden) with severe mental illness and substance abuse differs from other clients with substance abuse at the baseline and at follow-up one year later. We have used a quantitative method and analyzed material from ASI-interviews performed at the adult drug abuse unit at Södermalm during the time period 2002-2010. At the baseline the clients with substance abuse and co-occurring severe mental illness have more problems than other clients, primarily in the area of mental health. They spend more time alone and are more likely to engage in illegal activities. Interviewers assess their situation as more serious and that they need more help in all of ASI's areas of life than other clients.
