Emissions of biogenic volatile organic compounds (BVOC) are a chief uncertainty in calculating the burdens of important atmospheric compounds like tropospheric ozone or secondary organic aerosol, reflecting either imperfect chemical oxidation mechanisms or unreliable emission estimates, or both. To provide a starting point for a more systematic discussion we review here global isoprene and monoter

The fact that a growing number of pathogens develop resistance against traditional treatment is a growing medical problem. Infections, which until now have been harmless, might turn into life threatening diseases. These problems have led to an intensified search for alternative treatments. Analogs of cell surface glycoconjugates are an alternative. Ideally they prevent the adhesion of the pathogen

The concept “Broken Technologies” is related to the question: “Which is the benefit of humanity studies?” Of course the question is rhetorical because, how could this question be answered if the benefit was not obvious? Any answer supposes that we understand what we are asking for and the study of “what we mean” is one of the axes of the epistemology of the humanities. Anyway, we can also put the

For this purpose the starch microspheres can be coated by poly(DL-lactide-co-glycolide) (PLG) film, which is a release controlling. The term microsphere quality is complicated an

REDD is one of the latest additions to a series of incentive-based mechanisms for reducing carbon emissions. Although international negotiations have not eliminated uncertainties regarding its social, economic and political implications, many developing and emerging countries have begun to engage in REDD. Peru, the country with the world’s fourth largest tropical forest area has good reason to par

This thesis introduces and summarizes four papers dealing with the study of double and multiple stars using space astrometry. The introduction gives a brief review of the role of binary observations in various fields of astronomy --- star formation, stellar masses and the mass-luminosity relation, initial mass function, detection of sub-stellar mass companions. The astrometric techniques are also

The Swedish consumer magazine Råd & Rön (”Advice and Results”) has been available to Swedish consumers since 1958. For a major part of this time the Swedish state, represented by Konsumentverket (the Swedish Consumer Agency) and its predecessor, Konsumentinstitutet (the National Institute for Consumer Information), was the owner of the magazine. In 2006 Råd & Rön was sold to the independen

Popular Abstract in Swedish 10.SWEDISH SUMMARY(Populärvetenskaplig sammanfattning) Proteiner är viktiga byggstenar i cellen och är uppbyggda av kroppens tjugo olika aminosyror. Varje protein har en unik egenskap och spelar en viktig roll för cellens funktion. Vissa proteiner löser sig i vatten (hydrofila) medan andra är olösliga (hydrofoba). Membranproteiner är hydrofoba proteiner som är inbäddadeMembrane proteins are crucial components of the cell and are involved in many biological processes. Recombinant overexpression systems together with different purification methods are necessary to obtain large amounts of purified receptor for biophysical and functional studies. More knowledge about membrane proteins, and especially G-protein coupled receptors, would facilitate the development of i

Popular Abstract in Swedish Del 1. Introduktion I kapitel 1 presenteras arbetets problem, syfte och metod. Det arbete som olika frivilligorganisationer och deras medlemmar utför har de senaste åren uppmärksammats alltmer. Detta ökade intresse finner man såväl i Sverige som internationellt. Fokus i detta arbete riktas mot drivkrafterna bakom frivilligt engagemang. Det övergripande problemet är varfThis thesis focuses on the incitement to commitment and voluntary work. The overall problem is the question why you get involved in voluntary work for an organisation like Lutherhjälpen, the organisation for international development co-operation of the Church of Sweden, one of the largest NGOs of the country. The theoretical perspectives are seen from the position of the increasing pace of change

This doctoral thesis is comprised of five parts which deal with different signal processing problems in ECG-based characterization of atrial arrhythmias. Such characterization requires that the ventricular activity has first been cancelled in the ECG. In Part I, a new method for cancellation of the QRST complexes in recordings with atrial fibrillation is presented. The method is based on a spatiot

Popular Abstract in Swedish Att mäta det icke observerbara: Vilka chefer väljs till toppositioner? Rekrytering och urval av chefer präglas till stor del av informationsosäkerhet. Det är svårt att utvärdera chefers prestationer, då deras ansvarsområde består av så många aspekter, då de behöver stor frihet i sitt arbete och därför inte kan kontrolleras alltför mycket och då deras arbete påverkas avRecruitment and selection of managers is to a large degree characterized by information uncertainty. Managers’ performance is difficult to evaluate, as their responsibility consists of so many different aspects, as they may not always be observed due to need for freedom of action and as their work is affected by factors in their environment, which are outside of their control. Also, selection deci

Responding to an identified knowledge gap, the study aims to determine if smaller wind turbines located on top of existing urban buildings are more resource efficient (land utilization and economically) than large scale wind farms. To answer this question, using a GIS, the resource efficiency of the Roan wind farm in Northern Norway was compared to a theoretical modeled installation of small-scale

This master thesis was performed in collaboration with Orkla Foods Sweden AB. The aim of the study was to investigate rice pudding and how storage time affects the texture properties of the rice grains inside the pudding, and if this could be related to some of the properties of the raw rice. Rice pudding is produced by Orkla Foods under the label Risifrutti and is a popular in-between meal snack

Body size is one of the most important traits of zooplankton. It affects their metabolism, life history and ecology and can eventually influence community and ecosystem processes. Higher and more fluctuating temperatures due to climate change are expected to have an influence on zooplankton size. Based on general empirical evidence, warmer temperatures may lead to smaller zooplankton, while temper

I september 2014 antog FN:s säkerhetsråd resolution 2178, i ett försök att stävja strömmen av frivilliga som söker sig till terrorstämplade grupper i främst Syrien och Irak. Resolutionen uppställer krav på medlemsstaterna att införa nationell lagstiftning för att tackla problemet. Samtidigt definieras inte vad som ska anses utgöra terrorism och det saknas en geografisk eller tidsmässig avgränsningIn September 2014 the UN Security Council adopted resolution 2178 in an attempt to prevent the flow of so-called foreign terrorist fighters, a term referring to all foreign recruits who voluntarily join the ranks of UN-designated terrorist organisations. The resolution imposes upon member states far-reaching legal obligations to strengthen their domestic criminal laws. The scope of the resolution

In 2015 the EU introduced Directive 2015/720 on the reduction of the consumption of lightweight plastic carrier bags creating the first transnational agreement on plastic bag issue in the world. This Directive sets the scope within which Member States will design their own policies in order to reach a significant reduction in the plastic bag consumption over the following years. Greece is one of t

Nitrous oxide (N2O) is one of the three primary anthropogenic greenhouse gases. The agricultural sector accounts for 75.7 % of all anthropogenic N2O emissions in Germany (Umweltbundesamt, 2012). Thus, accurately estimating N2O emissions as well as mitigation strategies for N2O are crucial. This study optimizes the process-based model DNDC to simulate N2O emissions by conventional winter wheat and

Amelogenin is an enamel matrix protein which participates in the formation of dental enamel, the hardest tissue in the human body. The protein participates in this process by orienting the mineral crystals which make up the enamel and several proteolytic products from amelogenin also affect the dental enamel during its maturation. The protein is mostly hydrophobic with a hydrophilic region at the

På uppdrag från Trafikverket har en utredning om PAH-detektering inom vägteknik genomförts för att kunna ge förslag på hur de bör utforma ett kommande undersökningsprogram. Polycykliska aromatiska kolväten, PAH, är en grupp organiska föreningar som är en del av vägtjära.
