Datoranvändning inom förskolan : Ett lärtillfälle eller tidsfördriv?

AbstractThe purpose of this study is to see how technology is presented in different fictional picture books that are available in preschool. Six fictional picture books that have connection to technology in picture and text have been analysed. In order to show how technology can be made visible in fictional picture books, the relation between picture and text has been analysed through a technology perspective. Furthermore, the pictures and the texts have been analysed separately in order to show what they show respectively in terms of technology. The fictional picture book has a potential to be a basis for making technology visible in preschool, which is a step in a new direction.

Dyslexi och Likvärdighet : Finns det en genväg till en likvärdig utbildning?

The purpose of this paper is to find out if technology within pedagogy can help pupils with dyslexiaperform on the same level as their peers without using compensatory aid. Is it possible to replacethe compensatory aids with the technology in question? Can the same technology also be used tosupport other pupils as well and in turn removing the stigma of needing compensatory aid?To learn the answers to these questions I have done a qualitative text analysis. This analysis focuson technology in the form of podcasts and Web 2.0 based teaching platforms. The analysis alsofocus on pupils with dyslexia and what kind of help compensatory aids can be.

Fällning av kisel från avloppsvatten vid Hellisheidarvirkjun - experimentell studie

This report is about the experiments with mixing of the separated water and the vacuum pump seal water at Hellisheiði power plant. This is done to prevent silica scaling and clogging in pipes and reinjection wells as well as eliminating vacuum pump seal water from the plant. The experiments were done in four stages: the first stage comprised of tests with different flows of separated water at 70°C, the second stage was carried out by mixing the separated water at 70°C and the seal water with different amounts of the seal water, the third and the fourth stages were like the first and second but with the separated water at 120°C. The results show that this method is good if the mixture is around 50/50 separated water and seal water, to control the silica scaling in the separated water and to be able to reinject the seal water with the separated water. This does not eliminate the silica scaling in all of the separated water because the amount of separated water is much more than the amount of seal water that comes from the plant. .

Sample cradle prevents pre-analytic error on platelet counts but is not essential for hemoglobin measurement and prothrombin time

Introduction: It is recommended to place all the vacuum tubes directly on a sample cradle after vein puncture to prevent analytic error. This recommendation is not always easy to follow because the samples are taken by different professionals under different situations.  The three most common analyses, platelets count, haemoglobin and prothrombin time were tested.  Therefore, it was interesting to compare results from the three most common analyses with or without sample cradle, to evaluate the influence of this step on the result. Methods: Three analyses were preformed, using blood from 50 different persons. Each person gave two vacuum tubes, each contained 4.5mL of venous blood for the study.

Fotografen och bröllopsbilden : hur teknikskiftet från analog till digital teknik påverkat bröllopsfotografernas villkor och vanor

This paper examines how and if the understanding of wedding photography has changed during the shift of technology - from analog to digital photography. It examines if the changed conditions due to the shift of technology have changed the habits and conditions for the photographers working with wedding photography. It furthermore examines what impact these habits and conditions have had on the pictures of weddings. The investigation is based on interviews of six photographers that have worked professionally before and after the shift of technology, as well as of pictures by the photographers taken before and after the shift of technology.Use of time and space has changed due to the shift of technology. The change has also had an influence on hierarchy among the photographers.

Föslag till Estetisk Mångfald

I chose to do this work because I believe that today?s industrial designprofessionals lack in their task of creating aesthetic experiences and aestheticdiversity.With my work, I want to question why the majority of today?s technical, massproducedeveryday products have such a similar design expression, andwhy alternatives are so few. Most of all, I take a critical attitude to today?sstereotypical industrial design aesthetics that I would describe as technical,masculine, and unnecessarily complex.I have designed a number of products that show alternative aesthetics in thissegment and as such I have chosen the vacuum cleaner. The idea is that mydesign will serve as an eye opener and demonstrate that there are alternativesto today?s homogeneous market.The result is three vacuum cleaners claiming three alternatives to currentofferings.

VAC-behandling på öppna bukar - En enkätstudie som belyser för- och nackdelar med behandlingen i omvårdnadssituationer

Vacuum-Assisted Closure (VAC)-terapi är en omläggningsmetod som används alltmer på alla typer av sår. Behandlingen stimulerar sårläkningsprocessen genom ett negativt tryck som suger ut överflödig sårvätska och minskar infektionsrisken. Syftet med studien var att belysa för- och nackdelar med VAC-behandling på patienter med öppna bukar i samband med omvårdnadssituationer utifrån sjuksköterskors och undersköterskors uppfattning. En empirisk enkätstudie gjordes med kvalitativ ansats. Manifest innehållsanalys användes som metod för att analysera resultatet.

IKT - 2000-talets mentor? : En jämförande studie mellan manliga och kvinnliga pedagogers uppfattning om IKT i undervisningen

During the past decade Information Technology (IT) and Information and Communication Technology (ICT) have become the main tools in teaching. Authors and early educators who are treated in the study talks about how technology has come to change the school's approach to teaching and didactic tools. The technology has also affected students´ and teachers´ ways to work because the technology's versatility makes demands on the user's expertise and competence. The technical skills have long been associated as a male domain, where men are expected to master the technology´s versatility. These expectations are not the same for women.

Teknik- finns ett medvetet arbete med teknik? : En enkätstudie av pedagogers arbete med ämnet teknik i grundskolan, år F-5.

The purpose of this degree project is to study if there is a intentional work with technology in the elementary school, preschool to fifth grade, in a municipality. The work will also study what conditions there are in the schools in order to work with technology. 95 questionnaires were distributed to the responsible teachers in all primary schools in the municipality, from preschool to fifth grade. The results of the survey show that more than half of the respondents do not consider themselves to work with technology in the school. The conditions, in order to work with the school subject technology in the municipality, are primarily external such as: material, facilities and the ability to divide students into smaller groups.

Läcksökning med penetrant ? kvalitetssäkring av

Vacuum box leak testing is, because of geometrical problems, not always possible andtherefore an alternate test method with dye penetrant is used. DEKRA Industrial has identifieda need for quality assurance of the method and development of a written procedure withguidelines that lead to more uniform ways of testing.A literature study was done to get a general overview of nondestructive testing (NDT) and tosee how the method is used in different applications. European and American standards werestudied. Analytical and numerical solutions, involving flow simulation, were deemed to berather difficult and beyond the scoop of this project. Thus the problems had to be solved byusing experimental methods.
