Abstract The benthic macroinvertebrate fauna of 22 natural springs on Öland was sampled, by using a time-standarized kick/sweep sampling technique, in the end of September and early October. The aim was to determine the number of species and their abundances in the macroinvertebrate communities in springs and how/why these may change between different springs. Likewise there was a purpose to investigate possible differences between springs considering the proportions of the number of species and the abundances of the five functional feeding groups; shredders, collectors, filter-feeders, scrapers and predators. There was also an aim to investigate if the distances betweeen springs had any influence on similarity between the communities of benthic macroinvertebrates of the springs. Analysis from the springs collected material showed several interesting patterns in the number of species and their abundances when compared between springs devided into groups depending on their environmental factors such as depth and pH.

Master thesis work at ITN (Department of Science and Technology) in the areas of A/D-construction and RF-circuit design. Major goal of project were to research suitable possibilities for implementations of direct conversion in transceivers operating in the 160MHz band, theoretic study followed by development of components in the construction environment Cadence. Suitable A/D- converter and other important parts were selected at the end of the theoretic study. Subsampling technique was applied to make A/D sample requirements more realistic to achieve. Besides lowering requirements on A/D-converter it allows a more simple construction, which saves more components than subsampling adds.

The aim of this study was to find possible relations between behaviour and physiology for puppies during different parts of a puppy test. This work deals mainly with the physiological part of the study. Thirtysix puppies, från five litters, were tested in a behaviour test where heart rate was measured and saliva samples were collected before and after each part in the test. Saliva and urine samples were analyzed for corisol concentration as an indicatior of stress. The tests were performed during two consecutive days in the breeders' home when the puppies were seven weeks old. In addition, heart rate and cortisol levels were also measured in the bitch since we were interested in finding out if there were any relations between physiological levels in bitches and puppies.

Syftet med denna litteraturstudie är att sammanställa litteratur gällande olika typer av förband samt omläggningsfrekvens vid omvårdnad av central venkateter. Författarna har gjort en systematisk litteraturstudie och följt Goodmans sju steg i forskningsprocessen. Totalt inkluderades 15 vetenskapliga artiklar efter litteratursökning i databaserna PubMed, CINAHL, Cochrane Library samt via kompletteringar i ELIN. Artiklarna granskades av två oberoende bedömare utefter modifierade granskningsprotokoll och kvalitetsbedömdes därefter. Resultaten av denna sammanställning visar en tendens åt att sterila kompresser än så länge har ett litet försprång gentemot transparenta förband, i synnerhet när insticksstället inte läkt.

The thesis describes the following main question: Will the administrative labour during football tournaments be made easier with the help from a mobile web service or will it convey to unnecessary extra work? To be able to give a good and qualified answer to this question, the thesis will in the beginning describe how the technique for such a system might look like and also describe the existing administrative moments during a football tournament, this is too give the reader a deeper understanding for further reading. The thesis then goes on to describe a concrete system which is tested on three football tournaments. On the basis of the tests, interviews and through analysis of these the thesis will be able to answer our questions. The result which we present in the thesis have unfolded through testing of the system on three chosen football tournaments. The differences in way of labour pre and post the system have been analyzed and through interviews the value of these changes have been assessed. The results achieved in the thesis are as follows, the presented mobile web service does not only decrease the total work effort made by the tournament officials it also speeds up their work.

Background: Obesity surgery is the only technique that has proved to have a long-lasting effect on weight loss. Operation is not a solution but rather a lifelong involvement for the person. To loose a lot of weight means a big adjustment for both body and mind and the operated person may need support, advice, information and encouragement. Aim: The aim was to describe how a person, operated for obesity, can be supported in order to reach improved health pre- and postoperative. Method: A systematic literature study was made which resulted in 18 scientific articles that have been reviewed.

My intention was to explore the childhood of children and adolescents within the religious organization of Jehovah´s Witnesses, in Sweden. I used a technique where I interviewed three active witnesses and four former members. The former members either had left the religion freely or had been excluded by the movement. I wanted to know more from those two different perspectives, because they often seem to conflict. First of all, I wanted to learn about the persons own upbringing.

The purpose of this essay has been to study the different discourses that are expressed in social welfare secretaries? assertions when they assess cases with elements of honour-related violence, intimidation and oppression. To do so I have used a discourse analysis theory and technique, based on three qualitative interviews with social welfare secretaries. The interviews were focused on vignettes, which were all fictitious cases with various elements of honour-related violence. One of the interviews was a focus groupinterview with four participants, while the other two interviews were individual.

This master thesis takes its point of departure in the conflicting worldviews of modernism and post-modernism. As traditional segmentation theory springs from the modernist worldview, this study aims to contribute to the understanding of the complexity regarding market segmentation for lifestyle brands in contemporary society, where the consumer is often claimed to be post-modern. The research was conducted in Malmö and Lund and involved 25 Converse users as respondents. The methods used in this thesis starts with observations as a sampling technique in order to locate the respondents. Short interviews and photo documentation followed.

Syftet med denna undersökning var att förstå och beskriva sjökaptensstudenters upplevelser av handledning vid utförandet av uppgifter som krävs för att uppnå lärandemålen under delkursen Fartygsförlagd utbildning 1 (1FF01K). Halvstrukturerade personliga intervjuer genomfördes med åtta förstaårsstudenter mellan den 25:e mars och den 5:e april 2013. Dessa spelades in och transkriberades för att sedan tolkas och struktureras i olika kategorier beroende av upplevelser. Strategiskt urval användes för att välja ut informanterna vilka intervjuades med hjälp av ?critical incident technique?.

How do we perceive literature? In our times computer games and Internet have made us grow more comfortable to the usage of non linear storylines. But how does this apply to printed literature?In this essay, called ?From a to b through d h and o. Non linear storytelling in our time? I have focused on nonlinear literature from different time periods and I have studied novels such as James Joyce?s Ulysses as well as works by William S.

The objectives of this study was to examine the prevalence of hypertrophic cardiomyopathy in a family of British Shorthaircats to determine the mode of inheritance and to investigate if the disease was associated with a mutation in myosin binding proteinC (MyBPC3). The family comprised 28 cats, seven male and 21 females. The cats underwent a physical examination, including cardiac auscultation, and an ultrasound examination. Blood was collected for DNA- analysis. The blodsamples were sent in a buffer solution to Kathryn Meurs, Washington State University, USA for analysis, where the genes coding for MyBPC, Troponin I and T were characterized using microsequencing technique. Out of the 28 cats, 8 were diagnosed with HCM, 2 were diagnosed with congenital heart disease but had no evidence of HCM.

The point of departure for this thesis was an article written by Christer Hermansson (2008). He thinks that librarians, following the development of Library 2.0 and the change of public libraries, have strayed away from what he believes should be the focus of the library: Literature. The aim of this thesis is to study how librarians in six Swedish libraries perceive their occupational roles. How does the increased user control, which is seen as part of Library 2.0, affect the tasks of libraries and librarians? The material used in this study was acquired using a qualitative interview technique in which six librarians working in public libraries with experience of IT, mediation and purchase of literature partook.

People are usually directed towards each other in conversations, to make it easier to hear what is being said. Algorithms for voice and speech recognition works in a similar way, regarding the microphone direction towards the sound source. In this thesis in electronics has therefore a servo control with binaural sound localization been implemented on a microcontroller connected to two microphones.When people perceive sound, the brain can estimate the sound source direction by comparing the time taken by the sound reaching one ear to the other [1]. The difference in time is called the interaural time difference, and can be calculated using various techniques. An exploratory comparison between the techniques cross-correlation and cross-spectrum analysis was carried out before implementation.
