Dynamics of competitive polymer adsorption onto planar surfaces in good solvent.

Adsorption of mixed polymer solutions in good solvent containing polymers of different chain length has been studied by applying simulation techniques on a coarse-grained bead-spring polymer model. Fully flexible polymers at varying bead-surface interaction strength and different combinations of flexible, semiflexible, and stiff polymers at a single bead-surface interaction strength have been exam

Effect of temperature difference between manikin and wet fabric skin surfaces on clothing evaporative resistance: how much error is there?

Clothing evaporative resistance is one of the inherent factors that impede heat exchange by sweating evaporation. It is widely used as a basic input in physiological heat strain models. Previous studies showed a large variability in clothing evaporative resistance both at intra-laboratory and inter-laboratory testing. The errors in evaporative resistance may cause severe problems in the determinat

Getting used to assistive devices: Ambivalent experiences by frail elderly persons

The aim was to learn how frail elderly people experienced becoming assistive device users and how assistive devices affected their independence in daily activities. Focus-group methodology was used, including people 80 and older with multiple health problems. Five group discussions were conducted with a total of 18 people including 14 women and four men. Each group met once, for 90-120 minutes, an

Litteraturen som händelse och handling. Litteraturens performativitet i Sverige 1800 - 2008. Ett forskningsprojekt

Literature's ability to act - its performativity - is best shown in different performances, such as reading aloud, singing - in events. The different concepts and theories that form the foundation of an exploration of these performances in swedish culture in the period 1800 -2008 are presented, and also the organization of this exploration, eg a historical organization, structured according to dif

The ontological parsimony of mereology

David Lewis (Parts of classes, Wiley-Blackwell, Oxford, 1991, 84) famously argued that mereology is ontologically innocent. Many who have considered this claim believe he was mistaken. Mereology is not innocent, because its acceptance entails the acceptance of sums, new objects that were not previously part of one’s ontology. This argument, the argument from ontological parsimony, has two versions

Ultrafast Relaxation Dynamics of Uracil Probed via Strong Field Dissociative Ionization

We study the ultrafast relaxation dynamics of uracil excited to the first bright pi pi* state (S-2) by an ultrafast laser pulse in the deep ultraviolet (central wavelength lambda(0) = 260 nm). With a unique combination of strong field dissociative ionization measurements, state of the art strong field ionization calculations, and high level ab initio calculations of excited neutral and ionic state

Manual tracking enhances smooth pursuit eye movements

Previous studies have reported that concurrent manual tracking enhances smooth pursuit eye movements only when tracking a self-driven or a predictable moving target. Here, we used a control-theoretic approach to examine whether concurrent manual tracking enhances smooth pursuit of an unpredictable moving target. In the eye-hand tracking condition, participants used their eyes to track a Gaussian t

Chemical evolution of the galactic bulge as traced by microlensed dwarf and subgiant stars. II. Ages, metallicities, detailed elemental abundances, and connections to the Galactic thick disc

Context. The Bulge is the least understood major stellar population of the Milky Way. Most of what we know about the formation and evolution of the Bulge comes from bright giant stars. The underlying assumption that giants represent all the stars, and accurately trace the chemical evolution of a stellar population, is under debate. In particular, recent observations of a few microlensed dwarf star

The Fatty Acid Amide Hydrolase (FAAH) Pro129Thr Polymorphism is not Associated with Severe Obesity in Greek Subjects

Fatty amid acid hydrolase (FAAH) has been implicated at both protein and gene level with obesity. An association between Pro129Thr variant of the FAAH gene and obesity has been described, but various studies have yielded conflicting results. Our aim was to determine whether this polymorphism is related to severe obesity and whether it confers a risk for variability of quantitative metabolic traits

Cerebral Palsy and Neonatal Death in Term Singletons Born Small for Gestational Age

BACKGROUND AND OBJECTIVES: To investigate the probable timing of events leading to cerebral palsy (CP) in singletons born small for gestational age (SGA) at term, taking neonatal death into consideration. METHODS: In this registry-based cohort study, data on 400 488 singletons born during 1996-2003 were abstracted from the Medical Birth and the CP registries of Norway. Among 36 604 SGA children (b

Introduction to suspension levels: radiotherapy

In 2007, the European Commission (EC) commissioned a group of experts to undertake the revision of Report Radiation Protection (RP 91) oCriteria for acceptability of radiological (including radiotherapy) and nuclear medicine installations' written in 1997(( 1)). The revised draft report was submitted to the EC in 2010, who issued it for public consultation. The EC has commissioned the same group o

The COST 2100 Channel Model: Parameterization and Validation Based on Outdoor MIMO Measurements at 300 MHz

The COST 2100 channel model is a geometry based stochastic channel model (GSCM) for multiple-input multiple-output (MIMO) simulations. This paper presents parameterization and validation of the channel model for peer-to-peer communication in the 300 MHz band. Measurements were carried out in outdoor environments for both line-of-sight (LOS) and non line-of-sight (NLOS) scenarios. The COST 2100 cha

Delrapport: Test av vägledande system i en tunnel

I följande delrapport redogörs övergripande för förutsättningarna och delar av resultaten efter ett utrymningsförsök som genomfördes den 1-3 juli år 2014 i vägtunneln Norra länken i Stockholm. Syftet med försöket var i huvudsak att undersöka hur personer på bästa sätt kan ledas till en motstående tunnelvägg med utrymningsvägar i en rökfylld tunnel. Försöket syftade även till att kvantifiera med vi

This article focuses on the roles played by the female characters in three of the most influential indigenista novels, Raza de bronce (1918) by the Bolivian author Alcides Arguedas, Huasipungo (1934) by Jorge Icaza, from Ecuador, and El mundo es ancho y ajeno (1941) by the Peruvian writer Ciro Alegría. The roles of the female characters are studied from the perspective of Mikhail Bakhtin’s notion

Konsten att lyckas som par : Populärterapeutiska berättelser, individualisering och kön

Popular Abstract in Swedish Avhandlingen fokuserar den framväxande populärterapeutiska kulturen om och för heterosexuella par. Tre fallstudier har utförts; självhjälpsböcker för par, tv-program med relationsfokus samt diskussionsforum på Internet, kopplade till tv-programmen. Den populärterapeutiska kulturen analyseras och diskuteras i relation till teorier om vardagens psykologisering, samt teoriIn this thesis, the expanding discourse of popular therapeutic culture on and for heterosexual couples is analysed. Three case studies have been carried out; self-help books for couples, TV programs with relationship-focus, and web discussion boards connected to the TV programs. The analysis is made in relation to sociological theories of individualization, therapeutic culture, feminist studies of

Energy balance and global warming potential of biogas-based fuels from a life cycle perspective

Biogas is a multifunctional energy carrier currently used for co-generation or compressed biomethane as vehicle fuel. Gas-to-liquid (GTL) technology enables conversion of biogas into other energy carriers with higher energy density, facilitating fuel distribution. The energy efficiency and global warming potential (GWP) for conversion of biogas to compressed biogas (CBG), liquefied biogas (LBG),

Towards a molecular understanding of symbiont function: Identification of a fungal gene for the degradation of xylan in the fungus gardens of leaf-cutting ants

Background Leaf-cutting ants live in symbiosis with a fungus that they rear for food by providing it with live plant material. Until recently the fungus' main inferred function was to make otherwise inaccessible cell wall degradation products available to the ants, but new studies have shed doubt on this idea. To provide evidence for the cell wall degrading capacity of the attine ant symbiont, we
