Limited knowledge of the subsurface geology motivates the use of geophysical techniques before large engineering projects are conducted. These applications are normally restricted to satisfy the project aims, like mapping the near surface sediments, unconsolidated rocks and/or geological structures that may affect the construction locally. However, the applications can also contribute to the gener

In an often quoted sentence of his 1976 book "The Architecture of Form", Lionel March drew a clear distinction between science, interested in extant forms, and design, which initiates novel forms. The theories, methods, measures and diagrams of space syntax have often developed following this first more scientific scheme, and they have been concerned with the analysis of existing or projected buil

Idrottande ungdomar, i åldern 12-20 år, har ett specialbehov vad gäller kosten i jämförelse med andra individer. Då ungdomarna fortfarande växer och utvecklas är en sund kosthållning ytterst angeläget för upprätthållande av en normal kroppslig utveckling. Dessutom ställs i och med idrottandet högre krav på näringsintaget eftersom mer energi- och näringsämnen samt vätska förbrukas på grund av den fYoung athletes, between 12-20 years, have special dietary needs in comparison to other individuals. Since these individuals are still growing and maturing, a healthy diet is of utmost importance for the maintenance of a normal physical development. Moreover; due to physical activity the requirements of energy, nutrients and fluids are higher for young athletes. In order to achieve optimal physical

Popular Abstract in Swedish I denna avhandling har användbarheten av Virtual Reality (VR) utvecklats och undersökts för två användningsområden: participatorisk design av arbetsplatser och hjärnskaderehabilitering. Inom det första användningsområdet används VR tillsammans med fullskalemodellering, drama och demokratisk mötesteknik i en Visualiseringsverkstad. Denna arbetsmetod har utvecklats och t

This thesis deals with students' constructions of mathematical knowledge in the case of fractions from a radical constructivist perspective. Fractions are the first more abstracted mathematics met by students. Even if they have a rich experience of sharing and partitioning things in their everyday life dealing with fractions often give rise to difficulties in school. The thesis consists of two p

Popular Abstract in Swedish Syftet med denna undersökning är att diskutera inlärares signaler om hjälp att uttrycka sig på främmande språk, här franska, signaler som här kallas ?sollicitationer?. Undersökningen handlar om vilken roll dessa spelar för den fortsatta utvecklingen av samtalet med den infödde talaren, närmare bestämt för att utlösa s.k. SPA (Séquences Potentiellement Acquisitionnelles)

Popular Abstract in Swedish Arbetet med denna avhandling har handlat om en abnormal fosfolipid (fettämne) som bildas i kroppens celler endast när alkohol är närvarande, lipiden kallas fosfatidyletanol (PEth). För att lättare kunna förstå resultaten av våra undersökningar börjar jag med en kort bakgrund. Alla kroppens celler är omgärdade av ett membran som skiljer dem från varandra och omgivningen.

Popular Abstract in Swedish Intresset för förnybara bränslen har ökat stadigt under de senaste åren. Att byta ut fossila mot förnybara bränslen kan minska utsläppen av växthusgaser till atmosfären och därmed minska klimatpåverkan av dessa men även minska vårt beroende av olja. Biobränslen som t.ex. etanol, biodiesel eller biogas, räknas till förnybara bränslen eftersom de inte bidrar till en ackumReplacing fossil fuels by biofuels such as ethanol is considered a promising alternative to reduce greenhouse gas (GHG) emissions and mitigate climate change. Biofuels produced from lignocellulosic biomass, so-called second generation biofuels, result in decreased GHG emissions and limit competition with food and animal feed production. Interest in producing ethanol from lignocellulosic biomass ha

Microfluidics has emerged as an essential approach in the development of novel technological platforms to detect and isolate rare circulating tumor cells (CTCs) in the blood of cancer patients. Micro-scaled fluidic systems offer means to precisely control fluid flow. This enables cell separation when combined with techniques for manipulating cells across fluid streams. Various microfluidic methods

The aim of this thesis is to investigate the changes in vasoactive intestinal peptide (VIP) and calcitonin gene-related peptide(CGRP) and P2Y6-mediated signaling following experimental subarachnoid hemorrhage (SAH) and transient middle cerebral artery occlusion (tMCAO). VIP and CGRP are among the most powerful vasodilators known to man while P2Y6 mediates strong vasoconstriction in cerebral blood

AbstractThe overall aims of this thesis were to use echocardiography to non-invasively, delineate early structural andfunctional changes following orthotopic heart transplantation (OHT), and to define reference values in the contextof gender and bridging with mechanical circulatory support.Several factors might affect myocardial function in OHT patients rendering the use of normal values fortranst

Background: Helping consumers make healthier food choices is a key issue for the prevention of cancer and other diseases. In many countries, political authorities are considering the implementation of a simplified labelling system to reflect the nutritional quality of food products. The Nutri-Score, a five-colour nutrition label, is derived from the Nutrient Profiling System of the British Food St

Although fossils are relatively common in some sedimentary deposits, the majority consists of fragmented or distorted skeletal hard parts (such as shell and bones). However, in rare cases, special burial and diagenetic conditions have allowed a greater portion of the original anatomy to be incorporated into the fossil record. This exceptional type of preservation is characterised by the retention
