The calcium homeostasis in the body is normally strict regulated to be kept within very narrow limits. This regulation is due to the action of parathyroid hormone (PTH) which is synthesized in the chief cells of the parathyroid glands. In different diseases, the calcium homeostasis is disturbed and this could either be due to a dysfunction of the parathyroid gland itself, or it could have a completely different explanation. To investigate disturbed calciumhomeostasis, ionized calcium and PTH can be analyzed from a blood sample. There are a lot of different assays to measure PTH in humans.

The aim with this study is to explore if and how linguistic learning takes places when four pairs ofstudents in grade one writes on the computer. Observations of eight students took place duringtwelve lessons to investigate what happened during their writing processes. This study isimportant because students? computer writing is a relatively new phenomenon in the Swedishprimary school.It is clear that the peer collaboration creates a complex interaction that becomes the platform, andalso the prerequisite, for successful language training. The method can clearly give students profitsin their linguistic development.

Förnyelsebar energi är viktigt för att minska människans negativa miljöpåverkan. Ett steg i processen är optimeringav transmissionsnätet och investering i fler förnyelsebara energikällor, till exempel vinkraftparker.Vinkraftparker med enbart likströmsöverföring har lägre effektförluster än motsvarande växelström. Föratt ytterligare minska förluster i likströmsnät behöver spänningen ökas med DC/DC-omriktare. Syftet medstudien är att uppskatta vilken effekt en DC/DC-omriktare kan uppnå om den placeras i en 20? containervid botten av ett vindkraftverk, detta under förutsättning att modern teknik används.Studien presenterar en modell av DC/DC-omriktare i en container och beskriver hur beräkningarna harutförts.

Cycling is one of the most sustainable transport modes available and it is widely promoted inmany urban areas. The health benefits from cycling has shown to be substantial, includingdecreased risks of diseases related to overweight and enhancing brain capacity. However, inurban areas cyclists can temporaly be exposed to high levels of air pollution, resulting inhealth risks as opposed to health benefits.The objective of this thesis is to develop a rasterbased test model in GIS that estimates theinhaled dose of air pollution for cyclists based on relative particle concentration in differenttransportation micro-environments. The method used is a least-cost path approach,calculating three different routes; shortest, fastest and least dose for four different trips withinSödermalm, Stockholm.The results show that the inhaled particle dose can be greatly reduced, 39% - 58% for three ofthe routes, by choosing the least dose route. One of the most interesting findings is thesubstantial increase of dose when high levels of particles are combined with uphill cycling.The conclusion for the thesis is that a raster-GIS model can be very useful for estimating doseof different air pollution particles and chemicals along cycling routes.

In Sweden there is an integration policy and a policy for national minorities. The integration policy aims to integrate newly arrived immigrants (nyanlända invandrare), whereas the minority policy aims to maintain and strengthen the rights of the national minorities. The national minorities are though, at times, included into the integration policy, even though they hold a minority status in Sweden. This paper aims to, through discourse analysis, investigate the research question: ?how is the content of integration referred to, when it is related to immigrants, contra when it is related to national minorities?.

This report is about intranets and SharePoint. It explains how user?s expectations can affect an implementation of an intranet and what companies want to get out of an intranet. It?s also about risks that may occur when an intranet is developed and how to avoid these problems.SharePoint is a collaborative platform and publishing system from Microsoft that assists developers in the implementation of an intranet.

Distillers? grain is a by-product of ethanol production. Corn, wheat and barley are the grains that are generally used in the distillery process. Distillers? grain is rich in protein and phosphorus.

During 2001-2002 a prototype, IMIS (Integrated Mobile Information System) was developed at BTH (Blekinge University of Technology) to demonstrate how mobile IT-systems can be used in healthcare. The prototype was based on the activity theory of Engeström. An ongoing project started in spring 2003. The purpose of the project is further development of IMIS with special focus in the diabetes healthcare. Participants in the project are scientists and students at BTH, ALMI Företagspartner, Blekinge FoU-enhet, Barndiabetesförbundet Blekinge, Blekinge Diabetesförening, Vårdcentralen Ronneby and Vårdcentralen Sölvesborg.

Artikelns fokus ligger på smarta elnät och specifikt den distribuerade kontrollen av dem. Syftet med projektet var skapa hårdvaran och mjukvaran till ett distribuerat informations- och kontrollsystem för att kunna styra lasterna till en liten elnätsmodell, ICS byn (Industrial Information and Control Systems). Speciellt så skulle det undersökas om det var möjligt att skapa ett fungerande kontrollsystem med billiga kommersiella produkter, Raspberry Pi:s och Arduinos. Projektets resultat kommer sedan att användas för ett fortsatt utvecklingsarbete på ICS.För att skapa det distribuerade kontrollsystemet så användes JACK Intelligent Agents, en utvecklings miljö för multiagent system baserat åa Java. Rapporten tar upp de olika hårdvarukomponenterna Arduino, en mikrokontroller och Raspberry Pi, en linuxbaserad dator och transistorkretsarna som har byggts för att kunna driva de elektromekaniska brytarna i byn från Arduinon.

The purpose of this thesis is to evaluate three search engines with regard to retrieval effectiveness of information specific to Swedish users. Coverage and the precision in result descriptions are also examined. The three selected search engines are Google, MSN Search and Svesök. 30 queries were tested against the search engines and the first 20 result descriptions and results were judged for relevancy. Relevancy was judged by a binary scale.

Stadsmodeller i 3D är en allt mer bidragande faktor inom GIS och vinster i tid för räddningstjänst vid användandet av 3D-GIS har påvisats. Arbetet presenterat i rapporten behandlar nätverksanalyser i 2D och 3D och har utförts på uppdrag av Gävle kommun.  Uppgiften har utförts med två huvudsakliga mål. Det första målet var att jämföra processtiderna för Dijkstras sökalgoritm mellan nätverk (ett mindre baserat på förvaltningshuset i Gävle och ett överdimensionerat nätverk) i 3D och motsvarande nätverk i 2D, för att sedan avgöra skillnaden. Det andra målet var att utveckla en applikation som tillåter vägledning i 3D för besökare från reception till önskad anställd och få rutten visualiserad i en 3D-modell. Arbetet har i huvudsak genomförts med ESRI ArcGIS Desktop 10 och ArcGIS Engine 10 Developer Kit.

The purpose of this thesis is to evaluate and compare the retrieval effectiveness of two search engines on the Internet: Svensk Medicin and Google Scholar. Svensk Medicin is a medicine-specific search engine and Google Scholar specialises in indexing scholarly material. A set of 20 questions in four categories were used to conduct the searches with the search engines. Genuine medical information needs were selected from a question collection provided by the television program Fråga doktorn. The relevance of the first 10 retrieved documents was judged by using a binary scale and the measure used was precision.

In this study we have examined how teachers work with the documentation of formative assessment with focus on how to design the right technological support to make it more simple and more efficient. We have studied how teachers? work with documentation in practise based on the guidelines for formative assessment presented at the National Agency of Education. We performed observations and interviews in primary schools with teachers in different subjects in Ska?ne and Norrland.
