Metabola syndromet kopplat till fysisk aktivitet och konditionsstatus

Abstract  The development and onset of diseases such as cardiovascular disease (CVD) and Type 2 diabetes are closely linked to genetics and lifestyle factors including physical activity and diet. A cluster of metabolic disorders called the metabolic syndrome (MetS) is a high-risk factor in developing these diseases. Acording to the International diabetes institute, one fourth of the worlds adult population has MetS. These individuals are twice as likely to die from CVDs compared to individuals without MetS. Physical activity (PA) and exercise has been shown to provide a number of positive effects that are considered to reduce the risk of developing sickness and premature mortality among both men and women of all ages, independent of other risk factors.

Computer Modelling of the Influence of Surface Topography on Water Repellency and a Study on Hydrophobic Paper Surfaces with Partly Controlled Roughness

A computer model based on minimization of the free energy, capable to predict contact angles and spreading transitions between Wenzel and Cassie mode for drops placed on surfaces with different topography were implemented in matlab. Simulations were compared with experiments documented in the literature. These showed that reported transitions between Cassie and Wenzel mode can be explained by minimization of the free energy. In this report, a study on the possibility of constructing water repellent paper surfaces with a combination of treatment with octadecyltrichlorosilane and topography changes, is included..

Att skriva utan penna : En studie av datorns betydelse för skrivande på gymnasienivå

The purpose of this study is to investigate how important computers are for text production in upper secondary school level, and to find out what attitudes some students have towards computers in writing classes. I have let 44 students in the Swedish gymnasium course Swedish B write an argumentative essay. Half of the group wrote using paper and pencil, and the other half used computers. The essays were graded, and the language and length of the texts were analyzed. The students also filled in a questionnaire with questions on computer aided writing classes.The results showed that the texts that were written with computers contained a significant larger amount of words and fewer spelling mistakes.

Implementation av ett interface till Emotiv Epoc

The eld of Brain-computer interfaces (BCI) concerns linking together an external device with the brain of a human or an animal. By doing this the conventional use of a mouse or keyboard can be circumvented, which can greatly benefit people with different types of diseases that cause paralysis or other loss of motor control, such as Amyotrophic lateral sclerosis (ALS). A BCI can also be used for cognitive training of either healthy or mentally impaired subjects to increase cognitive capabilities.In this thesis an implementation of an interface is made against such a device, the Emotiv EPOC Headset. The result is meant to be a stable basis for further study using the device. An in-depth study of the history of EEG and its current use in clinical work and research in the topics of BCI as well as Human-computer interaction (HCI) is presented.

Framgångsrikt strategiarbete : ett arbete om visioner och strategier inom Region Gotland

The usage of visions and strategies is something that helps an organisation to create an imaginary scenario and guide them of how to realize these goals. During the years of 2006-2008 Region Gotland presented a document that was supposed to show the region's visions. The theoretical framework of this thesis is based on the stakeholder theory, Balanced Scorecard (BSC) and Management Control Systems Package (MCS). Personal interviews were conducted within the organisation Region Gotland, with individuals whom are directly linked to the visions and strategies of the organisation. The purpose of this study is to clarify the concepts of vision and strategy, and what their impact is on the organisation's work on the operation level.

Vi kallar personlighetstypen för kreativa dagdrömmare : En kvalitativ studie av professionellas erfarenheter och åsikter kring ungas dataspelsproblematik

Dataspelsproblematik är ett eskalerande problem som har visat sig påverka många unga människors utveckling och välbefinnande. Syftet med denna studie var därför att undersöka ungas dataspelsproblematik, vilka konsekvenser ett överdrivet dataspelande medför samt vilken behandling som ges till unga med dataspelsproblematik. Empirin erhölls genom kvalitativa intervjuer med professionella som arbetar med denna typ av problematik vid verksamheterna Game Over och Theory in Action. Resultatet visade att dataspelsproblematik idag inte har en bestämd definition och att det är ett problem som inte är tillräckligt uppmärksammat. Synen på orsaker till dataspelsproblematik hos unga är komplext då det kan tänkas bero på många olika faktorer.

Synt och sånt : Datorbaserat musikskapande på folkbibliotek, en studie i förutsättningar och praktik

Recent papers and bills from the Swedish Government deal with the possibilities  of giving all Swedish citizens the possibility of their own creative actlvities in the cultural sector. This work is about where such actlvities shall be placed in order to make them obtainable  for all. As an example of creative work this work takes computer-based music-making. At the public library in Odense, Denmark there is a weil functioning sound workshop where the public gets the opportunity of making music with some assistance from the staff. This work shows  that also in Sweden  the public libraries are the most suitable  institutions  for placing studies for computer-based music-making  for the public depending  on the public libraries'  traditions in adult education.

Dimensionering av betongplatta på lös undergrund. En jämförelse mellan tre beräkningsprogram

Today more effective computer programs are in use, regarding design of geotechnicalconstructions. There is a risk that the theoretical background of the computerprograms, its limitations and the signification of the choice of soil parameter isforgotten when the computer programs become more user-friendly.This Master thesis deals with simulation and analysis regarding three computerprograms, FEM-design, with the addition Raft, Plaxis and BE-slab. Comparisons aremade for settlement and maximum moment in a concrete-plate. FEM-design is a threedimensional FEM-program, foremost created for design engineers. Plaxis is a twodimensional FEM-program, intended for geotechnical engineers while BE-Slab is aBoundary elements program in two dimensions that is mainly used by designengineers.
