In scenarios coined Maxwell's demon, information on microscopic degrees of freedom is used to seemingly violate the second law of thermodynamics. This has been studied in the classical as well as the quantum domain. In this paper, we study an implementation of Maxwell's demon that can operate in both domains. In particular, we investigate information-to-work conversion over the quantum-to-classica

The role of natural marine aerosols in the global climate system remains understudied and uncertain. This is true for the emissions of natural volatile compounds over the ocean, the oxidation of said compounds and their impact on particle formation and particle growth. In this thesis, the emission, chemistry and aerosol particle processes relating to these compounds were studied using different pr

Sustainable products have arrived on the market and faced competition with traditional products with one extra challenge: they normally tend to be more expensive than traditional ones. Customers are yet to pay more for these products as they are alerted for environmental impacts. However, the gap between knowledge and action is being decreased slowly. One of the factors for this sluggish behavior

α-Galactosidases are important industrial enzymes for hemicellulosic biomass degradation or modification. In this study, six novel extracellular α-galactosidases from Penicillium subrubescens were produced in Pichia pastoris and characterized. All α-galactosidases exhibited high affinity to pNPαGal, and only AglE was not active towards galacto-oligomers. Especially AglB and AglD released high amou

When two putatively cryptic species meet in nature, hybrid zone analysis can be used to estimate the extent of gene flow between them. Two recently recognized cryptic species of banded newt (genus Ommatotriton) are suspected to meet in parapatry in Anatolia, but a formal hybrid zone analysis has never been conducted. We sample populations throughout the range, with a focus on the supposed contact

RationaleThere is no effective disease modifying treatment for peanut allergy available. A Phase I safety and tolerability study was performed with a chemically modified, Al(OH)3 adsorbed peanut extract (HAL-MPE1) for subcutaneous immunotherapy (SCIT).MethodsIn a randomized, double-blind, placebo controlled, single-centre, Phase I study, 17 Caucasian subjects with peanut allergy were randomized to

This article presents and discusses the case study “Scraping the surface,” aworkshop about sustainable design held for master’s students of different design majors at the FHNW Academy of Art and Design. Through marketing we, as consumers, are bombarded with products claiming to be sustainable. As a result, sustainability has become a buzz word. “Scraping the surface” highlighted the complex factor

Adjectives that are used to describe sensory experiences are often used to express more than one modality. The adjective sweet, for instance, may primarily be associated with taste (i.e., taste is the dominant modality of sweet), but it can also be used for smell, sound or sight, and possibly even for touch. It has also been shown that some sensory modalities combine more easily than others. Many

We show here the first colloidal synthesis of double perovskite Cs2AgInCl6 nanocrystals (NCs) with a control over their size distribution. In our approach, metal carboxylate precursors and ligands (oleylamine and oleic acid) are dissolved in diphenyl ether and reacted at 105 °C with benzoyl chloride. The resulting Cs2AgInCl6 NCs exhibit the expected double perovskite crystal structure, are stable

The purpose of this thesis has been to analyse the mechanism of the market driving approach carried out by a global organisation with a corporate brand. Market driving is a new organisational approach to strategy that lacks a solid theoretical framework, but constitutes a reality of global firms such as IKEA, The Body Shop, Benetton, Dell, Hennes and Mauritz, Starbucks. In the literature, the mark

Tillgången på kredit kan öka människors hälsa och välfärd, men mot bakgrund av att skulder så småningom måste betalas tillbaka är det samtidigt tänkbart att överskuldsättning kan ge upphov till försämrad hälsa. I denna rapport använder vi svenska enkät- och registerdata på individnivå för att närmare studera denna fråga. Särskilt undersöker vi sambandet mellan betalningssvårigheter och olika subje

A major question in organizations is how to support Business Processes (BPs) by an Enterprise Resource Planning (ERP) system. In this paper we present thoughts on designing implementation processes of ERPs using a Service Oriented Architecture (SOA) based perspective: The starting point is based on the idea of decomposing an ERP from a SOA based perspective and thereby supporting automation of imp

Transmembrane (TM) alpha-helical peptides with neutral flanking residues such as tryptophan form highly ordered striated domains when incorporated in gel-state 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC) bilayers and inspected by atomic force microscopy (AFM) (1). In this study, we analyze the molecular organization of these striated domains using AFM, photo-cross-linking, fluorescence spec

A large outbreak of enterohaemorrhagic Escherichia coli (EHEC) infections occured in southern Sweden during autumn 2002. A matched case-control study was performed and indicated an association between consumption of fermented sausage and EHEC infection (odds ratio 5.4, P<0.002). Pulsed-field gel electrophoresis analysis identified a strain of E. coli O157:H7 in clinical faecal isolates which was i
