Geopolitics on trial: politics and science in the wartime geopolitics of Gudmund Hatt

The history of Danish geographers during the Second World War is almost synonymous with that of Gudmund Hatt (1884–1960), the Professor of Human Geography at Copenhagen University. Hatt was a key figure in the development of Danish geography and assumed the role of a public intellectual, particularly through his geopolitical analyses as they unfolded in a staggering number of radio speeches, newsp

ICRP perspective on criteria of acceptability for medical radiological equipment

The International Commission on Radiological Protection (ICRP) does not have a specific publication or recent detailed advice on acceptability criteria and suspension levels for medical radiological equipment. However, a number of the Commission's publications clearly stress the need to carry out acceptance testing of radiological equipment. Such general recommendations are frequent in earlier and

Maximum likelihood analysis of mammalian p53 indicates the presence of positively selected sites and higher tumorigenic mutations in purifying sites

The tumor suppressor gene TP53 (p53) maintains genome stability. Mutation or loss of p53 is found in most cancers. Analysis of evolutionary constrains and p53 mutations reveal important sites for concomitant functional studies. In this study, phylogenetic analyses of the coding sequences of p53 from 26 mammals were carried out by applying a maximum likelihood method. The results display two branch

Carbonate mud mounds, conglomerates, and sea-level history in the Katian (Upper Ordovician) of central Sweden

The Katian (Upper Ordovician) facies succession of the Siljan district, central Sweden, records some of the most prominent environmental changes in the Ordovician of Baltoscandia. These changes include two separate phases of major sea-level drawdown that were of basinwide and presumably global importance. The first regression and lowstand terminated an entire generation of carbonate mud mounds (th

This dissertation deals with conversational practices through which interactants manage issues of intersubjectivity, i.e. mutual understanding for all practical purposes. Intersubjectivity is understood in a procedural sense, and as built into the infrastructure of interaction, where each next action embodies aspects of how the previous action was understood. This understanding can be inspected by

Fire, Poison, and Black Tears : Metaphors of Emotion in Rebétiko

Popular Abstract in Swedish Avhandlingen Fire, Poison, and Black Tears – Metaphors of Emotion in Rebétiko är som titeln anger en studie av metaforer för känslouttryck i rebétikomusikens texter. Den populärmusikaliska genren rebétiko är en utbredd musikstil i det moderna Grekland. Dess rötter kan spåras till det grekiska fastlandet, Mindre Asien, och de grekiska öarna, men den musikaliska formen haThis dissertation is a study of metaphors of emotion in rebétiko song texts. Rebétiko is a major popular-music style of modern Greece, consisting mostly of melancholic songs full of sorrow, disappointment, and misfortune, as well as passion and romance, but also of cheerful songs of revelry and a carefree attitude to life. Rebétiko as a music style developed in the Greek-speaking world and its dia

Asymptotics for the size of the largest component scaled to "logn" in inhomogeneous random graphs

We study inhomogeneous random graphs in the subcritical case. Among other results, we derive an exact formula for the size of the largest connected component scaled by logn, with n being the size of the graph. This generalizes a result for the "rank-1 case". We also investigate branching processes associated with these graphs. In particular, we discover that the same well-known equation for the su

Analysis of laser wakefield dynamics in capillary tubes

A general approach to the modifications of the spectrum of a laser pulse interacting with matter is elaborated and used for spectral diagnostics of laser wakefield generation in guiding structures. Analytical predictions of the laser frequency red shift due to the wakefield excited in a capillary waveguide are confirmed by self-consistent modeling results. The role of ionization blue shift, and no

Factor analysis in predominantly severe COPD: Identification of disease heterogeneity by easily measurable characteristics

Background: The clinical and demographic variables defining the heterogeneity of chronic obstructive pulmonary disease (COPD) are unclear. A post-hoc analysis of five randomised studies in patients with a history of previous exacerbations examined the clinical and demographic characteristics describing moderate-to-very-severe COPD. Methods: Factor analysis was performed on all continuous baseline

Interlamellar forces and the thermodynamic characterization of lamellar phospholipid systems

In this review, we summarize a series of experimental studies of the swelling of zwitterionic lamellar phospholipid and phospholipid-cholesterol systems using a novel double twin calorimeter. With this method, one can obtain simultaneous measures of the partial molar free energy and the partial molar enthalpy, and the experimental studies thus provide a complete thermodynamic characterization of t

Events with isolated leptons and missing transverse momentum and measurement of W production at HERA

Events with high energy isolated electrons, muons or tau leptons and missing transverse momentum are studied using the full e(+/-)p data sample collected by the H1 experiment at HERA, corresponding to an integrated luminosity of 474 pb(-1). Within the Standard Model, events with isolated leptons and missing transverse momentum mainly originate from the production of single W bosons. The total sing

Automated image-based assay for evaluation of HIV neutralization and cell-to-cell fusion inhibition

Background: Standardized techniques to detect HIV-neutralizing antibody responses are of great importance in the search for an HIV vaccine. Methods: Here, we present a high-throughput, high-content automated plaque reduction (APR) assay based on automated microscopy and image analysis that allows evaluation of neutralization and inhibition of cell-cell fusion within the same assay. Neutralization

Relative rate study of the kinetic isotope effect in the (CH3D)-C-13 + Cl reaction

The (CH3D)-C-13/(CH4)-C-12 kinetic isotope effect, alpha((CH3D)-C-13), of CH4 + Cl is determined for the first time, using the relative rate technique and Fourier transform infrared (FTIR) spectroscopy. alpha((CH3D)-C-13) is found to be 1.60 +/- 0.04. In addition, a quantum chemistry/transition state theory model with tunneling correction is constructed and the primary cause for alpha((CH3D)-C-13)

Antagonistic and synergistic effects of fungal and bacterial growth in soil after adding different carbon and nitrogen sources

The effect of adding easily available and more complex carbon sources, with and without nitrogen, on fungal and bacterial growth and activity in soil were studied in the laboratory. Total microbial activity was estimated by measuring respiration, fungal growth with the acetate-in-ergosterol incorporation technique and bacterial growth with the thymidine and leucine incorporation techniques. The su

Unraveling of free-carrier absorption for terahertz radiation in heterostructures

The relation between free-carrier absorption and intersubband transitions in semiconductor heterostructures is resolved by comparing a sequence of structures. Our numerical and analytical results show how free-carrier absorption evolves from the intersubband transitions in the limit of infinite number of wells with vanishing barrier width. It is explicitly shown that the integral of the absorption

Post-stroke functional limitations and changes in use of mode of transport

Purpose: To investigate the use of different modes of transport and long-term changes among stroke survivors with cognitive functional limitations (CFLs), and to study differences among sub-groups (decreased/ceased vs. unchanged and increased public transport use) regarding physical functional limitations (PFLs), CFLs, depression, and social activity outside home. Method: Survey of 79 individuals
