The membrane is often considered as the heart of the proton exchange membrane fuel cell (PEMFC), and it is of pivotal importance for the involved transport phenomena and performance of the entire PEMFC. The Nafion(R) membrane is the most commonly used type of membrane in PEMFCs. In this paper, the nano-scale structure of the Nafion(R) membrane is reconstructed using dissipative particle dynamics.

In the present work, fiber-based frequency-modulated light scattering interferometry (FMLSI) is developed and employed for studies of optical properties and dynamics in liquid phantoms made from Intralipid(®). The fiber-based FMLSI system retrieves the optical properties by examining the intensity fluctuations through the turbid medium in a heterodyne detection scheme using a continuous-wave frequ

Apolipoprotein M (ApoM) is a 25-kDa HDL-associated apolipoprotein and a member of the lipocalin family of proteins. Mature apoM retains its signal peptide, which serves as a lipid anchor attaching apoM to the lipoproteins, thereby keeping it in the circulation. Studies in mice have suggested apoM to be antiatherogenic, but its physiological function is yet unknown. We have now determined the 1.95

In order to allow different software applications, in constant evolution, to interact and exchange data, flexible file formats are needed. A file format specification for different types of content has been elaborated to allow communication of data for the software developed within the European Network of Excellence "NANOQUANTA", focusing on first-principles calculations of materials and nanosyste

Parkinson’s disease (PD) is a progressive neurodegenerative disorder, characterized by tremor, muscle rigidity and bradykinesia, which is primarily due to the degeneration of nigrostriatal dopaminergic neurons. Currently, patients are primarily treated with L-dopa and other drugs that enhance dopaminergic function. Those are effective during the first years, but eventually the majority of patients

BACKGROUND: The aim was to improve the realism of patient models for Monte-Carlo based evaluation of image-based quantification of tumour volume and activity in [68Ga]Ga-DOTA-TOC PET and [177Lu]Lu-DOTA-TATE SPECT images.METHODS: Three phantoms from the XCAT population were used as basis. Tumour structures were obtained from segmentation of patient 68Ga-PET images and positioned at relevant positio

In the fast-evolving arena of climate finance, equitable access to and allocation of funds for adaptation continue to pose a significant and urgent challenge. In theory, to prepare for the impacts of climate change in an equitable way, regional, national, and European Union (EU) funding tenders on climate adaptation should prioritize the most climate-vulnerable local administrations. However, evid

Lignins are a polymeric, renewable resource with remarkable structural diversity. Research is being conducted into the valorisation of lignins into value-added products. The absence of experimental libraries, in particular for process-modified oligomers, hampers analytical feedback to these valorisation efforts. Stochastic methods for generating libraries in-silico have been proposed, but were not

Lime-cement mixing is a method used for ground improvement of clay soils. Before mixing at a field site, laboratory samples are prepared and tested to decide the amount of lime-cement binder needed to reach the desired material strength. Strength measurements are not possible before a sample hardens, and the test process to predict final strength takes 30 days. Resistivity measurements are possibl

Water hyacinth is among the world’s most damaging aquatic invasive plants, forming dense mats that disrupt ecosystem functioning, fisheries, navigation, and livelihoods across tropical and subtropical freshwater systems. Its rapid spread is driven by clonal propagation, short life cycles, and prolific seed production, particularly under nutrient-enriched conditions. Although mechanical, chemical,

För ett flygbolag är det viktigt att ha en effektiv planering av sina resurser. Att kunna utnyttja personal och flygplan på rätt sätt är en förutsättning för en fortsatt överlevnad på marknaden. Flygbolagens tjänstebestämmelser regleras idag enligt nuvarande BCL-D 1.15. Under våren 2004 har Luftfartsverket behandlat en remiss som utgör ett förslag på en eventuell förändring av dessa tjänstebestämm

Populärvetenskaplig sammanfattning: Beskrivning och kartläggning av vegetationen samt tolkning av jord, klimat och annan information är mycket viktigt för förståelse och planering för användande av naturresurser. Fenologi dvs växters årliga variationer, är nära korrelerad med dynamiken i atmosfären. Information om vegetationens fenologi på regional och global nivå är därför en viktigt komponent föVegetation phenology (seasonal rhythm) is closely related to seasonal dynamics in the lower atmosphere and is therefore an important element in global climatic models and vegetation monitoring. Remote sensing is the primary means by which we can observe the dynamic characters of the earth's biosphere. Description and mapping of the natural vegetation, and its interpretation in terms of soil, c

In writing this study, I wanted to examine which principles of organization that are possible for Swedish public libraries to use, and what these principles mean for the libraries customerorientation. This is done by examining a number of written sources, as well as studying the organization of six public libraries. I found several possible principles, but a number of principles have been more com

By using data from Ecovision on the DJ AIG commodity index made up of commodity futures and the OMX index consisting of Swedish equities I have estimated the correlation between Swedish equities and US commodity futures. The correlation has been examined in a multivariate GARCH setting by using the BEKK model. The purpose has been to examine if commodity futures from a US exchange market can impro

År 1996 presenterade IMF och Världsbanken det så kallade HIPC-initiativet. Initiativet har inneburit omfattande skuldavskrivningar för HIPC-länderna. Uppsatsens syfte är att undersöka om HIPC-initiativet är ett effektivt verktyg för att gynna ekonomisk tillväxt. Med hjälp av teorier så som "debt overhang" och "crowding-out" samt empiriska studier från diverse ekonomiska forskar

Forskningsrön tyder på att organisatoriska och sociala faktorer är den största anledningen till att 90 % av implementeringarna av ERP-system misslyckas. Förespråkarna för involvering av användarna för lyckad implementering är många. I denna studie har vi belyst en fallstudie i en relativt liten livsmedelsorganisation där det har studerats vikten av kommunikation och kommunikationsrutiner för att t

The purpose of this thesis is to investigate if there is a risk that Sweden will go in to crises at the house market and in the bank sector. The Swedish house prices have in the last years growth very high and quickly and are now over the development in the beginning of 1990. The method I use to investigate this is a multiple regression model. I follow a regression that both OECD and the Swedish R
