The purpose of this thesis is to find out which analyzing methods that gives results and how the different methods can be combined and /or established in each other. The investigations centers around an embroidery, belonging to Tämta church, with unknown origin, use and age. The embroidery is long and narrow with applications in the form of dragons and eagles on a ground of velvet cloth. The dragons and eagles are covered with metal threads.

Ethics and Animal Experimentation in the Laboratory. A Critical Analysis of the Arguments for"Animal Rights"and"Animal Equality"

Growing up as a child, we had a Dog. To us, it was like a means to an end. That is, hunting other animals for food and for protection, with no special care and treatment given to this animal. Butas days passed by I began to witness a wind of change against such actions. I was made to understand that we were committing two crimes-: using the Dog as a means to an end (for hunting and for eating animals).

Comparison of Different Electrophoretic Methods for Haptoglobin Phenotyping and an Investigation in Patients with Abdominal Aortic Aneurysm

Haptoglobin is an acute phase protein with important biological role because of its capacity to bind to haemoglobin. Haptoglobin exists in three major genetic polymorphism types: Hp1-1, Hp2-1 and Hp2-2, the distribution of which has been associated with abdominal aortic aneurysm (AAA), an asymptomatic aortic disease common among men older than 65 years.    Five different electrophoretic methods were tested according to their ability to separate the haptoglobin phenotypes. The detection was based on a produced hemolysate of blood in which haemoglobin binds to haptoglobin thereby forming a complex that can be detected by specific haemoglobin staining using TMB-dihydrochloride and hydro peroxide as substrate resulting in an azure-green color of the bands. Samples from 15 patients who had suffered surgery for not broken AAA, that is more than5.0 cmaortic diameter, and 15 samples from matched controls were analyzed.    Among the five tested electrophoretic methods best migration and separation was seen on the pre-cast agarosgel Hydragel HR on the instrument Hydrasys. The other four methods gave less successful results.

Etik och censur inom internetfiltrering ? En forskningsöversikt

This paper is a research review in the realm of censorship systems andfiltering systems. It applies ethical considerations to the creation of censorshipsystems bringing forward discussion on the ethics of technology with thepurpose of limiting access to information.There is active research being done in the area of automatic content filteringand censorship systems. These are systems that can filter out undesiredmaterial, typically from the Internet, automatically. Used in some nations,many schools and even mandated in some libraries there are many ethicalquestions raised concerning censorship and access to information.Part of the review concerns the level of accuracy of these systems presentedby researchers in the field and the different approaches used. Reviewedarticles centre around automatic content classification and filtering ofpotentially harmful materials with regards to minors while some relate tocensorship technology in a wider sense.Results show a general lack of discussion concerning the ethics of thetechnology in the research reviewed.

Breast cancer stem cells : evidence and contradictory views

This literature study aims to examine the existence of cancer stem cells in breast cancer. The cancer stem cell theory states that there is a hierarchical organization within a tumour, in which a small subpopulation of the cells can initiate new tumours and maintain tumour growth whilst the bulk of the tumour cannot. These tumour initiating cells have shown to possess many characteristics similar to those of adult stem cells, which is why they are often referred to as cancer stem cells. Both cell types have the capacity of asymmetric division and have shown to possess mechanisms of resistance to both apoptosis and cancer drugs. The cancer stem cell theory elucidates many biological aspects such as the heterogeneity of tumours and the relapse of many cancers after what appeared to be successful treatments.

Sjuksköterskors upplevelser och erfarenheter av ofria luftvägar prehospitalt

The purpose of this study was to explore nurses' experiences of obstructed airways in the prehospital work.A qualitative interview study with a descriptive and explorative design was used. The sample consisted of nine registered nurses whereof three were women and six were men, with or without further education and varying length of experience in the ambulance service.Prehospital personnel builds up a vast plan of action based on the emergency information provided by SOS. Simple methods for managing obstructed airways were stated often enough. Problems with obstructed airways are considered so unusual that it never becomes a routine. Several factors affect the identification and managing of obstructed airways, both external factors and the different patient categories are considered important.

Forskningsområdet biblioteks- och informationsvetenskap vid Högskolan i Borås ? En bibliometrisk studie av den intellektuella basen 2001?2006

The aim of this study was to map the intellectual base at the Swedish School of Library and Information Science (SSLIS) at the University Collage of Borås, and to compare this intellectual base to the intellectual base of the research area Library and Information Science. This was done by analysing the citations in publications published, between the year of 2001 to the first quarter of 2006, by researchers at the institution, using the technique of author cocitation analysis. Cluster analysis and multidimensional scaling, statistical techniques that are traditional i the author cocitation analysis, formed an objective map of the intellectual base at the SSLIS. This map was then compared with three prior studies, that used the same technique to map the intellectual base of the research area. The result shows that the map of the intellectual base at the SSLIS consists of the specialities: user studies, library studies, culture/cultural policy, information retrieval, bibliometrics and information in organisations.

Hur menar du då? : En jämförande studie om kvinnors och mäns intervjuteknik i Gomorron Sverige

Syftet med denna uppsats är att jämföra manliga och kvinnliga programledares intervjuteknik i morgonprogrammet Gomorron Sverige. Under de 150 år som intervjun har utvecklats är den idag ett av journalistikens viktigaste redskap. Uppsatsen är baserad på teorier om hur man uppnår en bra intervjuteknik genom olika knep, samt teorier om genus inom journalistiken där den manliga och kvinnliga dikotomin diskuteras. Vi har valt att använda oss av metoden kvalitativ intervjuanalys, där vi har tagit fram frågor från teorierna och som vi sedan ställt till vårt material.Våra resultat visar att det finns många likheter i mäns och kvinnors intervjuteknik. Resultaten visar även att kvinnliga programledare har mer makt över intervjun genom sina frågor och hur de agerar.

Alumner från SLU, Skogsmästarskolan säger sitt

The purpose of this study is to investigate the forest managers view of the edu-cation at the School for Forest management at SLU and the first years of em-ployment. Surveys were sent to batches 05/08, 06/09 and 07/10 a total of 136 question-naires were sent out. 80 people answered the survey, this gives a response rate of 59 percent The former students rated according to a 9-grade scale how satisfied they were with the different courses they had attended during their years as students at the school. The courses in mathematics and statistics got the highest marks with an average of 7.3, while the entry-level course in law only got an average of 4.6. A major part of the former students had in the questionnaire enquired a leader-ship course and a business course with focus on negotiation techniques during their education. There is a wide variety of employment opportunities for the graduated students. Timber buyers and forest managers or planners are just a few positions that for-mer students now possess. The study shows that there is a big difference in the first introduction to a new work place depending on where the student got hired.

Observatörer för skattning av verktygspositionen hos en industrirobot : Design, simulering och experimentell verifiering

This thesis approaches the problem of estimating the arm angles of an industrial robot with flexibilities in joints and links. Due to cost-cutting efforts in the industrial robots industry, weaker components and more cost-effective structures have been introduced which in turn has led to problems with flexibilities, nonlinearities and friction. In order to handle these challenging dynamic problems and achieve high accuracy this study introduces state observers to estimate the tool position.The observers use measurements of the motor angles and an accelerometer and the different evaluated observers are based on an Extended Kalman Filter and a deterministic variant. They have been evaluated in experiments on an industrial robot with two degrees of freedom. The experimental verification shows that the state estimates can be highly accurate for medium frequency motions, ranging from 3-30Hz.

Utvärdering av ett auditivt diskriminationstest på 3-åriga barn

A speech-based material that early can assess a child's hearing is needed to provide an indication of a hearing impaired child's language development. Being able to identify and discriminate between different sounds is a requirement for interpreting speech. Hearing assessments that examine speech perception can therefore, unlike, for example, pure tone audiometry, examine a hearing impaired child's perceptual language skills and provide a basis for intervention.The purpose of this work is to evaluate a new auditory material on 3-year-old children. The auditory material is based on the Ling-6-sounds and the main question was which of the sounds in the test were adequate for test of discrimination. Furthermore, it was investigated how the test works with children aged 3:0?3:11 years and how age and gender affect the result.Twenty-four children aged 3:0?3:11 years were tested using a computer based test.

Patienten och sjukhusbiblioteket. En diskursanalys av uppfattningar om sjukhusbibliotek och deras betydelser för patienten i tre svenska bibliotekstidskrifter

The aim of this Masters thesis is to study opinions about the Swedish hospital libraries and their activities for the patients, in a selection of Swedish library journal articles. The theoretical starting point is grounded in Laclau and Mouffes discourse theory. The empirical material consists of 43 articles from three library journals; Biblioteksbladet, Blänkaren and DIK-forum, published between 1990 and 2004. These are analysed through a reading scheme in four levels. In the empirical material two themes appear; the culture theme and the patient information theme.

I Normalitetens Gränsland : hur närstående berättar om en kvinnas övernaturliga förmåga

My essay explores how people talk about a woman´s supernatural ability in relation to normality and abnormality. In order to find this out I´ve made interviews with people inclose relations to Hildur Lawergren. Hildur lived all her life in Fole on Gotland where she was often interviewed in local papers and on the radio about her predictions on the coming weather. She used melted candles to make her predictions. The candles were melted down on Christmas eve.

Bankers identifieringsmetoder : Nu och i framtiden

Keywords: ID-method, internet, security, digitzing, bank Background: The digitizing of our society continues to grow and more parts of our lives is spent on the internet. The banks are one of the institutions that is at the forefront of this development since they established themselves on a early basis. The banks meeting points have since this establishment moved from the regular bank office out on the internet. A problem that has occurred during this transfer is the possibility to positive ID a customer in a virtual world. It is essential to offer the customer methods to identify themselves that are both safe and easy to use.
