Konstruktion av instrument för dragprov på nervceller

This report describes how the system may be exposed to oscillations and how this can lead to resonance. Resonance is a phenomenon that occurs when a system is affected by external periodic oscillations with frequencies close to the system's natural frequencies. Structures subjected to resonance can risk great damage and destruction, why resonance is something that is important to take into account when designing structures. Alternative ways to counteract resonance is to supply damping in the system. Damping means that the resonance decreases instead of letting the amplitude increase.The report discusses some examples on constructions that have experienced the effect of resonance.

Sketching a set of multi-touch design principles

Today multi-touch technology is the basis for many new techniques designed to improve interactions with computers and mobile devices. It seems that multi-touch screen interface makes the user handling very natural in the sense that there is no need for a manual in how to interact with the object on the screen. The aim with this paper is to establish a fundamental set of design principles intended specifically for large multi-touch interfaces. To reach this goal we have implemented a couple of sub-goals beforehand: It was essential that we acquired a good understanding of the current state of the multi-touch interface and the different implementations that exist today. To make this possible we constructed a multi-touch display, "Rosie". Knowing how the hardware is produced today will help us understand the limitations and also the possibilities of the design implementations today and in the future. We also needed to devise a sound interaction design process that conveys the modern designers work.

Flyktingars upplevelse kring traumatiska händelser

The purpose of this study was to gain insight into refuges experience of traumatic events such as torture, political persecution, war, natural disasters and other trauma. For the study used theories which, inter alia, deals with many of the refugees coming to Sweden is influenced by various psychological trauma and may be accompanied by torture, political persecution, war, natural disasters and other trauma. To this study, a survey with 40 participants, 17 women and 23 men. There was also an interview on the Internet with a refugees consultant within the Red Cross. The men had higher average than women in all the perceived problems.

Olikhet, gemenskap, kommunikation : En studie om hur lärare i skolår 1-6 främjar tolerans hos elever.

For most pupils homework is a natural part of school and their education and there are several providers of homework assistance: the pupil's parents, sibblings, friends, Internet forums, hired private tutoring, non-profit organisations and at times even the pupil's school. This study has investigated the use of the school-based homework assistance programme at the Upper Secondary School of Psychology in Stockholm and why the programme is not more frequently used by its pupils. The school offers homework assistance two hours each Thursday afternoon, with at least two teachers being present to tender for the school's 127 pupils. The cost of the programme has been estimated to approximately 12 500 Swedish kronor per week. Through the main use of a questionnaire given to both the school's students and teachers, as well as an interview with the school's headmaster, this study will show that despite receiving the opportunity few pupils take part of the programme on a regular basis.

Högläsningens betydelse för barnens språkutveckling

The main thing we wanted to find out with this thesis was, can reading aloud help the natural language development. We also wanted to know how libraries in Sweden work with reading aloud and if children with reading and writing problems are being helped by being read to. We also wanted to find out what authoritarians on literature think a good reading-aloud novel should contain. To find this out we decided to do a literature study, we have taken part of a number of authoritarian opinions on this matter and we also studied some theories on this subject. We also decided to do a couple of interviews to exemplify how regular libraries work with reading aloud.

Gruppchefens förmåga

The Swedish armed forces has for many years educated squad leaders by letting them start their training two and a half months before the soldiers start their training. 2007, this system was used for the last time. I went trough this system myself in 2005 and had a positive experience and when I did my internship I experienced a slight difference in the attitude of the squad leader. I talked with my colleges at the company and they had felt the same. This essay will try to analyse if the squad leaders has lost any of there ability and if so, what could be the cause? To analyze the ability of the squad leader in this essay it will first analyze their ability through the Direct leadership theory, which is the theory that is presently used in the Swedish armed forces.

Marktillstånd och borbrist på åkermark planterad med gran i Västerbottens län :

This study was made on former agricultural areas that had been planted with spruce or pine, in the county of Västerbotten. The goal of the project was to investigate suspected deficiency of boron in these areas. Several objects have been reported for possible deficiency and some of these have the characteristic symptoms of boron-deficiency. The hypotheses are that 1) Boron deficiency is present at several of the investigated objects. 2) Planting of forest on cultivated postglacial sediments leads to a successive podzolisation with a decreasing content of organic matter in the mineral soil, due to decomposition, and a decreasing pH in the soil, even on locations that have been added lime. To be able to confirm or reject the hypotheses a number of tests were performed.

Skolan har fatta', det nya är surfplatta! : Implementation av surfplattor i grundskolan.

During the last two decades, technology has developed rapidly. It has become a natural part of everyday life, which we today take for granted. It isn?t until the last few years that technology has quickly become a big part in the school environments. Computers, tablets and other technology is today a big part of the education and teaching.

SAB och Dewey vid Uppsala universitetsbibliotek : En attitydundersökning bland bibliotekarier på 6 biblioteksenheter

The Library of Uppsala University has decided to change their classification system from the Swedish SAB system to the American Dewey Decimal Classification. One of the main reasons for this decison was that Kungliga biblioteket also has made an exchange between these systems. Due to that, the national bibliography of Sweden classifies Swedish documents according to Dewey Decimal Classification and the SAB system is no longer maintained. A transition to Dewey Decimal Classification will enable Swedish librarians to import foreign catalouge posts and classification codes and will provide them with a common standard between their libraries and other libraries due to the use of the same international classification system. It is disputed whether the Dewey Decimal Classification is equally suitable for all subjects.

Människans suveränitet över andra arter : En studie om två miljöorganisationers resonemang angående förlusten av biologisk mångfald

The purpose of this study is to exam how two environmental organizations reason about the loss of biodiversity. The research questions are; what is the view in these organizations regarding biodiversity? What are the underlying environmental discourses behind their reasoning, and how do they reason about the risks associated with the loss of biodiversity? As a first part of this thesis a thorough review of existing literature and online resources about the actions of environmental organizations was conducted. Two organizations were interviewed, World Wildlife Fund (WWF) and Naturskyddsforeningen. The questions for the study were analyzed in light of Dryzek´s (1997) reasoning about environmental discourses and using the concept of risk by Beck (1998).

Värdet av skapande i förskolan : En studie om pedagogers förhållande till skapande verksamhet i Stockholm och i Tornedalen

The purpose of this study was to investigate how preschool pedagogues in Stockholm and in Tornedalen speak about and relate to creative activities. By qualitative interviews in two geographically distant areas, one minority culture and one majority culture, I have collected information from six pedagogues, three in each area. Values in, and the significance of culture in creative activities have been the main focus. From this study I conclude that all pedagogues agreed upon the creative activity having an extensive role in the preschool work. The role of the individual pedagogue within the creative activity is multiple and dependent on where, when and how the activity is carried out.

Små barns motorik : En studie om hur pedagoger i förskolan arbetar med motorik i naturen

Syftet med denna undersökning är att undersökaPedagogernas syn på barns motoriska utveckling med inriktning till naturmiljö samt om pedagogerna är medvetna om forskningen kring barns motoriska utveckling med inriktning på naturmiljön. Studien bygger på kvalitativa intervjuer. Intervjuerna gjordes på fem olika förskolor med sex olika pedagoger, både förskollärare och barnskötare. Förskolorna var placerade i en mellan stor kommun i Sverige. De intervjuade jobbade på 1-3 års avdelning, då detta var vald åldersgrupp för undersökningen. Av resultatet framgår att pedagogerna är ute i naturen olika mycket och detta beror på olika faktorer. Det är dock medvetna om fördelarna som naturen har med sig för den motoriska utvecklingen och kan inte se några nackdelar med naturen för den motoriska utvecklingen.Pedagogerna är till viss del medvetna om forskningen kring ämnet, men de anser att medvetenheten är olika från pedagog till pedagog. Slutsatsen av studien är att pedagogerna är medvetna om de fördelar som naturen har med sig för den motoriska utvecklingen och samtliga vill vara ute mer i naturen.

Dödsrikets livshistorier : Benkemiska isotopanalyser på artikulerade och disartikulerade individer i Frälsegårdens gånggrift

The aim in this thesis is to use carbon, nitrogen and sulfur isotope analysis on teeth and bone to track diet and mobility of the population as well as the individual level from the articulated and disarticulated individuals from the passage grave Frälsegården, situated in Gökhem parish in the region of Falbygden, western Sweden.50 human samples were analyzed from tooth, mandibula and femur, together with 11 faunal samples from different bone elements of local wild and domestic animals.The results fall well in line with earlier stable isotope work done on passage grave individuals from Falbygden in stable isotopes: A homogenous group with a diet which was clearly terrestrial and lived on a pretty high trophic level. It also seems that the analyzed individuals deliberately focused their food intake to the cultural and natural, megalith and limestone landscape of Falbygden, and not to its surroundings, even if the passage grave is situated in the outermost areas of the region.A small study compares the sulfur results to with earlier work done on strontium isotopes. The results show that the different methods might provide a deeper understanding in the interpretation of the methods, and therefore suggesting that further work should be done to compare the methods..

Kritisk diskursanalys av skönlitterära genreutbrytningar i folkbibliotekets litteraturförmedlingskontext

This master?s thesis aims to study the practice of separating popular genres of fiction from the rest of the fiction stock, often seen at public libraries. The method being used is critical discourse analysis according to Norman Fairclough?s three-dimensional conception of discourse. The textual dimension of this analysis is the book shelf itself and the sociocultural practice is the everyday practice at a public library of supplying and mediating books to the visitors.
