We study upscaling of gas high harmonic generation, to make efficient use of the ever increasing laser pulse powers. Loose focusing geometries optimizing phasematching are investigated and compared in HHG efficiency to shorter focusing arrangements.

The heat recovery system for ventilation is of major importance when low energy buildings are built. One alternative to the mechanical ventilation systems with heat recovery is to use a brine based run-around system that allows for heat recovery in for instance hybrid ventilated buildings. This type of heat recovery system has the potential to lower the need for electricity for the fans.

Exposure to inorganic arsenic (iAs) is a risk factor for cancer. Alterations in mitochondrial DNA copy number (mtDNAcn) and telomere length (TL) have been associated with cancer risk. Two Argentinean groups were studied: A) Puna area of Andes and B) Chaco. Arsenic exposure was assessed as the sum of arsenic metabolites (iAs, MMA, and DMA) in urine (U-As) using HPLC-HG-ICPMS. MtDNAcn, TL, and genot

We study the effect of managerial power on CEOs' tendency to imprint their personal leverage preferences upon the firms they manage. Using a unique data source that allows us to measure personal wealth and indebtness in great detail, we find a connection between CEOs' personal leverage and that of their firms. The connection is driven by the CEOs with a longer tenure and the CEOs who serve in a du

How come that the Armenian genocide, a century old issue, is still a highly topical question, academic as well as political, in our days? My dissertation intends to follow the development of the Armenian question since WWI, with focus on the past half century, starting on the 50th commemoration day on April 24, 1965. The aim is to understand how the question has evolved during these years, identif

Ecological impacts of urbanization include the loss of biodiversity and changes in species composition and population densities. However, how the urban environment affects fundamental physiological parameters is largely unknown. Here, we investigated physiological components related to health and nutrition, namely, plasma fatty acids (FA) and lipid peroxidation at inter-habitat and interspecific lEcological impacts of urbanization include the loss of biodiversity and changes in species composition and population densities.

This thesis investigates the interface between external impressions of an organization, often referred to as its brand and image, and internal expressions, its culture and the identity of its employees, in organizations that have suffered crises of confidence. More specifically, the thesis seeks to problematize the alignment ideal in the corporate branding perspective (de Chernatony, 2001; Harris

Background: An early report on the molecular subtyping of muscle-invasive bladder cancer (MIBC) by gene expression suggested that response to neoadjuvant chemotherapy (NAC) varies by subtype. Objective: To investigate the ability of molecular subtypes to predict pathological downstaging and survival after NAC. Design, setting, and participants: Whole transcriptome profiling was performed on pre-NA

Emily Baird and Gavin Taylor describe how you can make three-dimensional models of biological samples using x-ray micro-computed tomography

The effect of fuel ethanol content (10, 85 and 100 %) on primary emissions and on subsequent secondary aerosol formation was investigated for a Euro 5 flex-fuel gasoline vehicle. Emissions were characterized during a New European Driving Cycle (NEDC) using a comprehensive setup of high time-resolution instruments. A detailed chemical composition of the exhaust particulate matter (PM) was studied u

We present a hierarchical self-organizing map based system for online recognition of human actions. We have made a first evaluation of our system by training it on two different sets of recorded human actions, one set containing manner actions and one set containing result actions, and then tested it by letting a human performer carry out the actions online in real time in front of the system’s 3D

This study investigates interaction in dialogues between children with language impairment (LI) and peers of different ages and at two different times, taking into account the language skills of the children with LI. The hypotheses tested were that dialogues between more mature children are more coherent and that the degree of language problems of the child with LI is not directly associated with
