This paper describes the development of a method based on measurements of the radar cross section (RCS) in the forward direction to determine the extinction cross section for the 2.5 – 38 GHz frequency range. A conventional anechoic chamber designed for monostatic measurements is used for forward RCS measurements. The extinction cross section is then calculated from the measured forward RCS using

Popular Abstract in Swedish Trots att vi har ett mycket sofistikerat immunförsvar är infektionssjukdomar ett stort problem för alla flercelliga organismer. Varför har vi inte under evolutionens gång lyckats finna ett sätt att överlista virus, bakterier och andra parasiter? En förklaring är att immunförsvaret är kostsamt, dvs att ett kraftfullt immunförsvar inte bara ger fördelar i form av ökat skyA central assumption of theories of the ecology and evolution of immunological defence is that defence has not only benefits (in the form of resistance against parasites), but also costs. The aim of my studies was to investigate the nature and magnitude of costs of the vertebrate immune system, and to examine some of the consequences of these costs. First, I investigated the energetic cost of the

In this anthology are gathered 28 essays, devoted to the interrelations of the arts and media. They present together the current state of the emerging field of Interart Studies. The contributors – Stephen Greenblatt, Claus Clüver, Erika Fischer-Lichte, John Neubauer, Steven Paul Scher, Walter Bernhart, Ulrich Weisstein, Eric Haskell, Eric Vos, Thomas Elsaesser, among others – are leading internati

A measurement of the Lambda(0)(b) lifetime and mass in the decay channel Lambda(0)(b) -> J/psi (mu(+) mu(-))Lambda(0)(p pi(-)) is presented. The analysis uses a signal sample of about 2200 Lambda(0)(b) and (Lambda) over bar (0)(b) decays that are reconstructed in 4.9 fb(-1) of ATLAS pp collision data collected in 2011 at the LHC center-of-mass energy of 7 TeV. A simultaneous mass and decay time ma

In 1919 the now largely forgotten popular novelist E.M. Hull sparked a decade of infatuation with the ‘desert romance’ on the publication of her first book, The sheik. The obsession with the genre, fuelled by the release of Melford's 1921 film adaptation of the book, saw women swooning in the aisles at ‘screen god’ Rudolph Valentino's starring role. My aim here is to broaden the focus on Hull away

Knowledge of a patient's perception of her medical needs and urgency may make it possible for emergency nurses to communicate the triage decision and make the patient understand the assessment and triage category. The aim of this study was to compare the patients' own assessments of their acuity to the triage nurse's assessment, as well as describe patient satisfaction and levels of anxiety.

We tested whether bacterial communities of subarctic heath soil are adapted to elevated temperature after experimental warming by open-top greenhouses for 7 or 17 years. The long-term warming by 1-2 degrees C significantly decreased bacterial community growth, by 28% and 73% after 7 and 17 years, respectively. The decrease was most likely due to decreased availability of labile substrate under war

Behavioural syndromes, that is correlated behaviours, may be a result from adaptive correlational selection, but in a new environmental setting, the trait correlation might act as an evolutionary constraint. However, knowledge about the quantitative genetic basis of behavioural syndromes, and the stability and evolvability of genetic correlations under different ecological conditions, is limited.

Reprint of chapter in C. Shore and D. Haller, 'Understanding Corruption: Anthropological Perspectives' from 2005. Discusses doing good and corruption fighting as a new wave, with a focus on the international NGO Transparency International.

This thesis provides the first attempt to study the nicotinamides and benzamides from a mode of action point of veiw. Understanding the effects on DNA repair, cell cycle control (proliferation) and cell death from these agents and in combination with ionizing radiation, provides a new opportunity to logically develop better approaches to sensitize already existing therapies via for example inducti
