Modeling mesoscopic solidification using dissipative particle dynamics

Dissipative particle dynamics with energy conversion (DPDe) is a simulation technique that has been used to model thermal transport characteristics and heat transfer at mesoscale. This study shows further development of the DPDe method capturing solid/liquid phase-change phenomena and its application to water freezing in a parallel-plate straight channel. In this work, the weighting functions of t

Probing and modifying the empty-state threshold of anatase TiO2: Experiments and ab initio theory

O 1s x-ray absorption spectroscopy (XAS) in conjunction with photoelectron spectroscopy has been used to explore the conduction-band edge of single crystalline and nanostructured anatase TiO2. The experiments are supported by ab initio density-functional calculations in which both the initial and core hole final states are considered. The calculations show that the states at the conduction-band ed

Insikt och närvaro : akademiska kontemplationer kring buddhism, meditation och mindfulness

Popular Abstract in Swedish Under 1900-talet har stora förändringar skett i synen på buddhistisk meditation. Från att ha varit en övning som bara ägt rum på kloster och bland ett fåtal munkar, har både ordinerade lärare och lekmannalärare börjat lära ut meditation till lekfolk. Meditation har kommit att framställas som själva hjärtat i buddhistiska traditioner, och som det element som kan isolerasThe purpose of this study is to investigate how a religious tradition changes when transposed to a new context: how it is received and incorporated in its new context and how individuals in Sweden perceive and make use of this tradition. This is done by highlighting the development of insight meditation, Vipassana, and more specifically, the Burmese practice lineage originating from the Burmese la

Fibromodulin and chondroadherin in connective tissue homeostasis

Popular Abstract in Swedish Syftet med studierna i denna avhandling har i huvudsak varit att förstå funktion för de två proteinerna fibromodulin och kondroadherin och deras samspel med övriga komponenter i bindväven. Dessa två proteiner fungerar som byggstenar och tillhör en familj av proteiner lokaliserade i bindväven i den så kallade extracellulära matrisen utanför cellerna. Bindväv återfinns i Connective tissue contains a prominent extracellular matrix (ECM), which provides for physiological and mechanical properties. Intra- and inter-molecular interactions between proteins in this ECM provide for the formation of molecular networks. These interactions determine the shape of the tissue as well as cell behavior. This thesis is focused on the leucine-rich repeat proteoglycans fibromodulin

Study of the on-route operation of a waste heat recovery system in a passenger vessel

Waste heat recovery systems for power generation are gaining interest among the marine transport sector as a solution to accomplish the upcoming more restrictive regulations on emissions, and to reduce the total fuel consumption. In this paper we evaluate how a waste heat recovery system based on a regenerative organic Rankine cycle (rORC) could improve the performance of a passenger vessel. The c

Leading Logarithms in the Massive $O(N)$ Nonlinear Sigma Model

We review Buchler and Colangelo's result that leading divergences at any loop order can be calculated using only one-loop calculations and we provide an alternative proof. We then use this method to calculate the leading divergences of and thus the leading logarithmic corrections to the meson mass in the massive $O(N)$ nonlinear sigma model to five-loop order. We also calculate the all-loop result

Abstract in French L’objectif de l’étude présentée dans cet article est d’examiner comment des apprenants du français langue étrangère de différents niveaux interprètent des extraits d’interaction authentique. Pour cela nous avons sélectionné des extraits de la base de données CLAPI, tous présentant une forme de désaccord entre les locuteurs. Dans une première étape, nous avons analysé les extrait

‘Let’s Get Them Involved’ . . . to Some Extent: Analyzing Online News Participation

The development of social media applications, such as blogs, Facebook, and Twitter, has offered new participatory opportunities for everyday media users. This article contributes to research by looking into one specific aspect of the increasingly more participatory media ecology—the news comment feature. Drawing on a quantitative content analysis of 1,100 news pieces, as well as spaces for user co

Increased Cause-specific Mortality in Patients with Mild and Severe Psoriasis: A Population-based Swedish Register Study

Several studies have shown excess risk for a number of comorbidities in patients with psoriasis compared with the general population, but data on cause-specific mortality in this patient population are limited. The aim of this study was to estimate the associations of psoriasis and 12 specific causes of death and all-cause mortality in patients with mild and severe psoriasis. The study was based o

Behavioural consequences of sensory plasticity in guppies

Sensory plasticity, whereby individuals compensate for sensory deprivation in one sense by an improvement in the performance of an alternative sense, is a well-documented phenomenon in nature. Despite this, the behavioural and ecological consequences of sensory plasticity have not been addressed. Here we show experimentally that some components (vision and chemoreception) of the sensory system of

Palaeoglaciation of Bayan Har Shan, northeastern Tibetan Plateau: glacial geology indicates maximum extents limited to ice cap and ice field scales

Key locations within an extensive area of the northeastern Tibetan Plateau, centred on Bayan Har Shan, have been mapped to distinguish glacial from non-glacial deposits. Prior work suggests palaeo-glaciers ranging from valley glaciers and local ice caps in the highest mountains to a regional or even plateau-scale ice sheet. New field data show that glacial deposits are abundant in high mountain ar

Reduced ozone by air filtration consistently improved grain yield in wheat

This study considered effects of reduced [O-3] on wheat yield. Open-top chamber charcoal filtered air treatments were compared with non-filtered treatments for field-grown wheat. 30 experiments meeting requirements were found, representing nine countries in North America, Europe and Asia. 26 experiments reported improved yield and 4 experiments reduced yield by filtration, a significant positive e

Controlled exposure to particulate matter from urban street air is associated with decreased vasodilation and heart rate variability in overweight and older adults

Background: Exposure to particulate matter (PM) is generally associated with elevated risk of cardiovascular morbidity and mortality. Elderly and obese subjects may be particularly susceptible, although short-term effects are poorly described. Methods: Sixty healthy subjects 25 males, 35 females, age 55 to 83 years, body mass index > 25 kg/m(2)) were included in a cross-over study with 5 hours of

HAMLET interacts with lipid membranes and perturbs their structure and integrity.

BACKGROUND: Cell membrane interactions rely on lipid bilayer constituents and molecules inserted within the membrane, including specific receptors. HAMLET (human alpha-lactalbumin made lethal to tumor cells) is a tumoricidal complex of partially unfolded alpha-lactalbumin (HLA) and oleic acid that is internalized by tumor cells, suggesting that interactions with the phospholipid bilayer and/or spe

Identification of the sex pheromone of the spruce seed moth, Cydia strobilella L.

The spruce seed moth, Cydia strobilella L., is a serious pest on cones of spruce (Picea spp.) in the Holarctic region. Previous studies from different parts of its area of distribution have reported conflicting results on the composition of its sex pheromone. By gas chromatography with electroantennographic detection, coupled gas chromatography-mass spectrometry, a Y-tube olfactometer bioassay, an
