Semiconductor nanowires are studied by using transmission electron microscopy (TEM) based methods in this work. In the first section, the growth mechanism of gallium arsenide nanowires grown by chemical beam epitaxy is investigated. The nanowires are epitaxially grown from a gallium arsenide substrate by using gold seed particles as catalysts. The growth of gold particle catalysed nanowires is oft

We present an integrated approach that solves the structure and motion problem for affine cameras. Given images of corresponding points, lines and conics in any number of views, a reconstruction of the scene structure and the camera motion is calculated, up to an affine transformation. Starting with three views, two novel concepts are introduced. The first one is a quasi-tensor consisting of 20 co

Döden är ett evigt tema. Men diskursen runt döden i dess mångskiftande former är underkastad ständig förändring. Döden kan ses som ett hot och ett gissel men också som en befrielse, ett straff eller som ett redskap för att befria samhället från oönskade individer. I samtliga fall kan man tala om döden som en reningsprocess – som katharsis. Det är denna föränderliga diskurs som kommer att behandlas

Popular Abstract in Swedish I vår omgivning finns många gasformiga ämnen, vars egenskaper är sådana att de kan mätas med optiska metoder. Härvid kan man utnyttja det unika spektroskopiska fingeravtryck ämnena har. Det vill säga, att varje ämne absorberar ljus av olika färg (våglängd) på ett unikt sätt. Likaså har vissa ämnen sådana egenskaper, att då de belyses med en viss våglängd sänder de ut enMulti-spectral lidar (light detection and ranging) techniques have been developed and employed in various environmental studies, ranging from concentration mapping of volcanic emissions to fluorescence imaging of historical monuments. In both absorption measurements of gaseous species and fluorescence imaging of stones, multiple wavelength excitation and multiple wavelength detection have been app

122 patients with Alzheimer's disease receiving galantamine in the Swedish Alzheimer Treatment Study were studied with respect to longitudinal change in cognition (MMSE and ADAS-cog) and function (IADL, PSMS and FAST). Particularly the FAST mean change from baseline showed a linear relationship with cognitive mean change and the strength of the relationship increased over time. The IADL scale demo

Popular Abstract in Swedish Sedan urminnestider har vi utsatts för attacker av virus, bakterier och andra för kroppen skadliga ämnen. Som svar på detta har kroppen utarbetat ett speciellt försvarssystem, det så kallade immunsystemet. När kroppen angrips aktiveras immunsystemet som står färdigt att bekämpa inkräktaren av vad slag det vara månde. Till sin hjälp har det många förfinade verktyg. BlandSecretory leukocyte protease inhibitor is a 11.7 kDa acid stable serine protease inhibitor. SLPI has been shown to be the dominant protease inhibitor in bronchial secretions and has been used in treatment of pulmonary emphysema. In ulcerative colitis faecal extracts has been shown to contain an abundance of free proteolytic activity, mainly leukocytic and pancreatic proteases. SLPI is a strong inh

This paper reports on the in-context evaluation of an audio-tactile interactive tourist guide - one test was done in a medieval city center, and the other was done at an archaeological site. The activity theory framework was used as a perspective to guide design, field-study and analysis. The evaluation shows that the guide allows users to experience an augmented reality, while keeping the environ
