Sleepless in Örebro : Effekter av kognitiv terapi med beteendeexperiment på ungdomar med primär insomni
Sömnsvårigheter hos ungdomar är ett växande problem i Sverige men det saknas forskning om behandlingsmetoder för åldersgruppen. Syftet med studien var att testa kognitiv terapi med beteendeexperiment (KT-I) på gymnasieungdomar med primär insomni. Studien genomfördes enligt en Single Subject design med för- och eftermätning. Tre ungdomar i åldern 16-18 genomgick en sju veckor lång behandling efter 1-2 veckors baslinjemätning. Resultatet visade att svårighetsgrad av insomni minskade, att funktionsförmågan dagtid förbättrades och behandlingsmålen uppfylldes i hög grad.
Debuten av gluten ? Har tidpunkt för glutenintroduktion någon betydelse för risken att utveckla celiaki hos högriskbarn?
AbstractTitle: The debut of gluten ? Does timing of gluten introduction affect the risk ofceliac disease in high-risk children?Author: Sandra Hagwall Frohm and Maria IngmarSupervisor: Frode SlindeExaminer: Mette AxelsenProgramme: Programme in dietetics, 180/240 ECTSType of paper: Bachelor?s thesis in clinical nutrition, 15 hpDate: May 26, 2015Background: Celiac disease is a chronic disease in which the intestinal mucosa is damaged bygluten exposure, and the only treatment is a lifelong gluten-free diet. The disease affects about1 % of the population worldwide, but the majority are undiagnosed. Ingestion of gluten and thegenotype HLA-DQ2/8 are required for disease development, although additional genetic andenvironmental factors are believed to be of importance. One hypothesis is that timing of glutenintroduction in infants affects the disease risk.
Digitala tjänstens registreringsprocess ? hur påverkar den helhetsintrycket?
The outset of this thesis is to raise questions on how we design for the mobile context and the capabilities of smartphones. Not only the presentation but also the use of input and interaction between a service and a user.This work evolves around sign up forms and answers the question: How does the sign up process affect the holistic perspective of a digital service regarding usability and user experience?
This thesis consists of a case studies, and design experiments conducted on Twitter, Instagram and Randos sign up processes to explore if and how the usability, and the user experience could be affected and im- proved.This concluded some important aspects to be considered when designing sign up forms for a digital service.The usability, and the user experience is not only affected by user interaction, and the choice of input method but it?s also affected by which data the service is requesting, and more important; if that data is motivated to request by the service..
Demokratiutveckling i svenska kommuner : en komparativ studie ur deltagardemokratisk synvinkel
The main purpose of this paper is to examine and compare the democratic situation and developement in Malung and Nyköping, through a perspective of participatory and deliberative democratic theories. The questions I?ve examined are On what priorities the actions of developing democracy are built? Which positive effects have been reached and what problems have arisen? What are the solutions they have found to the problems? How does one experience the results of the experiments and actions taken? What are the similarities and differences between the two cases? and What is their relationship to the theories mentioned above?The questions are answered through interviews with four central actors in each case and examined in relation to participatory and deliberative democratic theories and in comparison of the two cases.The results have been that even if none of the cases respond to one theoretical ideal, they have touches of both theories as well as representative theory. It shows, however, that in Malung the representative democracy theory is the strongest represented in actions and politics, while in Nyköping the participatory democratic theory is stronger. In short, the most positive and negative effects respond well to the theories..
Avskiljning av uran från dricksvatten med reaktiva filter :
Water is our most important provision and its quality is above all dependent on the
geological conditions in the area from where it is extracted. Due to geological
properties there are certain areas with an elevated risk of high uranium levels in the
ground water, which in turn constitutes a risk for human health. Consumption of water
that contains a high concentration of uranium implies a health risk due to the chemical
characteristics of uranium. Livsmedelsverket (The National Food Administration) and
Socialstyrelsen (The National Board of Health and Welfare) therefore recommend that
precautionary measures should be taken when the uranium concentration in ground
water exceeds 15 micrograms per litre. In particular, drinking water collected from
wells in areas with uranium-rich bedrock may have a harmfully high level of uranium.
One of the wells of the Ärla water purification plant, located near Eskilstuna, Sweden,
contains water that exceeds the guideline of 15 micrograms per litre.
One interesting technique for removing uranium from drinking water is adsorption to
reactive filter materials.
Djurägarbehandlingar inom renskötseln :
The aim of this study was to document treatments of sick and injured reindeer in Tornedalen and the area around Gällivare. I also wanted to find out the basis for the treatments, how they are considered to work and if they agree with established veterinary science. The occurrence of ?folk remedies? was especially studied. In all, 40 reindeer owners were interviewed.
Optimalt mottagningsstall för kalvar : en fältstudie
A cattle producer that buys calves that are younger than six months to the herd should have a starter stable to prevent infection spreading in the herd. According to the Swedish animal welfare regulation there has to be a starter stable if more than 50 calves that are younger than four months are bought in yearly to the herd. The aim of the study was to improve the knowledge about bovine buildings and management of starter stables to obtain optimal weight gain and health of the calves. The hypothesis 1) The younger the calves are when purchased, the higher the calf mortality and 2) Purchasing calves from a high number of herds involves a higher risk of calf health problems and calf mortality were tested in the study. The objective of the study was to give advices by way of presenting ideal solutions of how a starter stable should be constructed and managed.
A field study was done during June to September 2008 to collect knowledge and experience from existing starter stables.
Löslighet och metylering av kvicksilver i en förorenad sjö (Ala-Lombolo) i Kiruna kommun :
Transformation of inorganic mercury (Hg) to methyl mercury (MeHg) is a biotic process that is proposed to be conducted primarily by sulphate reducing bacteria (SRB). The formation of MeHg is of great interest because it is the mercury species that biomagnifies to the greatest extent in the aquatic food webs; about 90 % of all Hg in fish is MeHg. Our understanding of factors involved in the production of MeHg is very important for making a reliable risk assessment. The purposes of this study were to investigate the different factors that control the solubility of Hg and the production of MeHg in a contaminated lake sediment.
The lake Ala-Lombolo, Kiruna municipality, is well-known to be contaminated by mercury from different sources. Sediment cores were sampled at three different locations (N, SW and SE) in the lake and divided in three different layers; 0-5, 5-10 and 10-15 cm.
Askåterföring värt besväret? : en fallstudie av följderna av Stora Ensos försöksverksamhet med askåterföring
This thesis reports on a case study of a forest company, Stora Enso, and their experience from a number of trials and experiments with ash recycling. A literature survey and a total of eleven in-depth interviews were carried out. Ash recycling was found to be the concern of three different divisions of the company. The pulp industry which produces the ash, the forest division which would be responsible for identifying land and spreading the ash, and Stora Research, which has had a major part in the design and implementation of research trials. Lacking an overall company decision on ash recycling the matter is left to the individual divisions.
Housing of ringtailed lemur, Lemur catta, from an ethological perspective
Sheep production is the only animal production in Sweden that is increasing. Therefore,increasing knowledge of the production is of great interest. In order to run a viable sheepproduction, producers needs to be successful in the breeding of the animals and achievean economic surplus in the end. Lambs that are born healthy and vital have greaterconditions to perform high lamb weight gains and thus a successful production. Thereare many factors affect the survival, birth weight and early weight gain of the new bornlamb.
Dygnsvariation av metanemission från en anlagd våtmark
The aim of the study was to investigate if methane emission in a constructed wetland changed in a diurnal pattern correlating to temperature, humidity or light conditions. The gas measurements were carried out with a static chamber technique. The wetland (in Nykvarn outside of Linköping, Sweden) takes care of wastewater to reduce the nitrogen loads. Measurements were carried out at three different occasions in the summer of 1998 on two sites in the wetland. One site was close to the inflow, inhabited by Lemnaceae, and another site was located further downstream inhabited by the emergent macrophyte Typha latifolia.

Tillväxt hos Husmossa (Hylocomium splendens) i boreal skog och växthus : effekter av ökad vattentillgång
Hylocomium splendens (Glittering wood-moss) is a common species in the Nordic countries and can be found in many different types of boreal forests. It usually forms dense moss carpets on the forest floor. The shoots grow in segments and new segments form annually on the previous years growth. The size of the segments is probably regulated in a high extent by local micro environmental conditions. Previous experiments suggest increased growth of H.
Elevers attityder till och intresse för skolans fysiklaborationer/Pupil?s attitudes and interests to school?s physics laboratories
Undersökningens huvudsakliga syfte är att ta reda på hur elever uppfattar experiment och laborationer inom ämnet fysik. Ett annat syfte är att kartlägga elevuppfattningar om grupparbetet inom det laborativt arbete som kan ha betydelse för elevens aktivitetsgrad och lärande. Som grund för detta examensarbete har vi använt oss av en kvantitativ enkätundersökning som genomförts på 250 elever i grundskolans senare årskurser och gymnasieelever som läser natur eller teknikprogrammet. Resultatet av undersökningen visar att eleverna tycker att det är intresseväckande med laborationer, de ser till viss del kopplingar mellan deras vardag och fysikundervisning och de tycker att de lär sig mer genom att laborera. Dessa uppfattningar stämmer väl med vad didaktisk forskning anser vara syften med laborationer..
Stålbalkars bärförmåga vid intryckning - orsakad av lokal momentbelastning
This master thesis deals with steel girders subjected to patch loading caused by concentrated moments. There exist no good methods to calculate by hand the ultimate resistance for this load case. In ?tunnplåtshandboken?, (Handbook for sheet metal, which is published by SSAB), one calculation method is presented. It?s however fairly difficult to use, because of many calculation steps and many graphs.
