An updated detailed kinetic mechanism for ozone combustion is developed. The contemporary choice of the reaction rate constants is presented with emphasis on their uncertainties. Model predictions are compared with available experimental data for ozone decomposition flames and with the Moscow State University (MSU) mechanism used elsewhere in the literature. These two models show similar performan

Introduction: Human body acceleration is often used as an indicator of daily physical activity in epidemiological research. Raw acceleration signals contain three basic components: movement, gravity, and noise. Separation of these becomes increasingly difficult during rotational movements. We aimed to evaluate five different methods (metrics) of processing acceleration signals on their ability to

Tourist research on life in "The Experience Economy" has led to a focus oil the eventful cold dramatic, on ways of packaging and marketing "great experiences" that turn a heritage into all event, a city into desires, a museum into all adventure. There is a lot of talk about the production of great atmospheres and exciting events, but tourist life is of course full of non-events, indifferent or bad

Paraphrasing Slavoj Zizek (1991: 65), the paper proposes that: 'The Scania Truck does not exist': it is nothing but 'the symptom of passionate users', its power of fascination masks the void of its nonexistence'. Along the same line of reasoning, it argues, again paraphrasing Zizek, that 'the customized Scania truck is becoming the sinthome of its user'. (c.f. Zizek, 1991: 137). The paper does so

Natural and artificial light-harvesting processes have recently gained new interest. Signatures of long-lasting coherence in spectroscopic signals of biological systems have been repeatedly observed, albeit their origin is a matter of ongoing debate, as it is unclear how the loss of coherence due to interaction with the noisy environments in such systems is averted. Here we report experimental and

Objective Anti-neutrophil cytoplasmic antibodies and anti-Saccharomyces cerevisiae mannan antibodies (ASCAs) have been detected in the serum of patients with ulcerative colitis (UC) and Crohn's disease (CD) and their unaffected family members. The aim of this study was to establish the value of serological markers as predictors of UC and CD. Design Individuals who developed CD or UC were identifie

We review the theoretical motivations and experimental status of searches for stable massive particles (SMPs) which could be sufficiently long-lived as to be directly detected at collider experiments. The discovery of such particles would address a number of important questions in modern physics including the origin and composition of dark matter in the universe and the unification of the fundamen

Cadmium is a well-known nephrotoxic agent in food and tobacco, but the exposure level that is critical for kidney effects in the general population is not defined. Within a population-based women's health survey in southern Sweden (Women's Health in the Lund Area, WHILA), we investigated cadmium exposure in relation to tubular and glomerular function, from 1999 through early 2000 in 820 women (71%

In this paper we present evidence for a surface resonance on the (6v root 3 x 6 root 3)-R30 degrees-reconstruction obtained on 5 monolayers (ML) of An deposited on the (root 3 x root 3)-R30 degrees-4H-SiC(0001) and subsequently annealed. We use synchrotron radiation-based angle resolved photoelectron spectroscopy to show that this resonance has no k(parallel to)-dispersion, but a parabolic-like ki

Popular Abstract in Swedish Under 1850-talet framträdde baptismen som den första verkliga frikyrkorörelsen i Sverige. Den tog helt och hållet avstånd från det ordinära kyrkolivet och kom därför i konflikt med samhällets religiösa regelverk. Kyrkliga och världsliga myndigheter betrktade baptismen som villfarande och samhällsupplösande. Deras agerande mot baptisterna i landets södra delar blir i denDuring the 1850's, Baptism appeared as the first real free church movement in Sweden. It distanced itself completely from normal church life and therefore came into conflict with society's religious rules. Ecclesiastical and temporal authorities regarded Baptism as erroneous and social disruptive. In the present treatise, their actions against the Baptists in the southern parts of the country beco

For further investigations in the field of artificial photosynthesis, a model compound, 1, has been developed to mimic the electron-transfer steps from the manganese cluster to P680+ in photosystem II. In this model compound the photosensitizer ruthenium(II)-trisbipyridyl was linked to a manganese(II) ion through a bridging ligand. Photoexcitation of 1 in the presence of the electron acceptor meth

Femtosecond laser pulse control of exciton dynamics in biological chromophore complexes is studied theoretically using the optimal control theory specified to open quantum systems. Based on the laser pulse induced formation of an excitonic wave packet the possibility to localize excitation energy at a certain chromophore within a photosynthetic antenna system (FMO complex of green bacteria) is inv

The functional role of aerobic lactate production in the rat portal vein was investigated. Changing substrate from glucose (11.5 mM) to pyruvate (11.5 mM) or beta-hydroxybutyrate (3 mM) had virtually no effect on spontaneous mechanical activity. Lactate production (FLA) was smaller with pyruvate than with glucose (0.05 +/- 0.01 vs. 0.14 +/- 0.03 mumol g-1 min-1, n = 4). Addition of 0.5 mM iodoacet
