The PIXE method constitutes a tool for fast, reliable multi-elemental analysis of small samples. These properties are very attractive in aerosol sciences and in aerosol monitoring programmes. Thus PIXE allows the use of small samplers which are easy to deploy and could be operated for long periods even at more or less remote sites. For working environment aerosols, samplers with time resolution ca

Popular Abstract in Swedish Organisationskreativitet och psykologiskt v älbefinnande. I den föreliggande avhandling föreslås det att hur kreativitet och innovation uttrycks i organisationen är kontextberoende. Att kreativitet och innovation kan bidra till en ekonomisk tillväxt är allmänt känt. I denna avhandling föreslås det att kreativtet och innovation också kan leda till ett bättre psykologisktOrganizational creativity and psychological well-being. Present day organizations in a globalized society are experiencing external challenges and changes more than ever before and in order to adapt and react to these changes creativity and innovation are seen as some of the most important means. The standpoint in this thesis is that all employees have creative potential, and how the creative pote

Popular Abstract in English People normally associate hemoglobin with blood. It is true that the iron in the center of the hemoglobin molecule makes it excellent at carrying oxygen in the bloodstream from the lungs to every part of the body. However, seventy five years ago a hemoglobin was found in a plant. And plants do not have blood. So what is hemoglobin doing in plants? What are its functionsHemoglobins (Hb) are usually associated with blood in humans. However, these proteins are widely distributed among living organisms. In plants the most known group are the leghemoglobins. Still, other Hbs that not participate in symbiosis are also found. They are known as nonsymbiotic Hbs (nsHbs). NsHbs are divided into class-1 and class-2. In this thesis three nsHbs from sugar beet (BvHb1-1, BvHb

In this study, we will show that children, in their 2L1 acquisition, begin with the adverbs from the lower part of the hierarchy, and start using their higher level adverbs clearly later on, which seems to support a Structure Building Model. Inversely, we will show that adult L2 learners, even from the very earliest stages of acquisition, use the adverbs from the highest levels, which indicates th

Critical infrastructures provide indispensable services to society and extensive disruption of these give rise to large societal consequences. Most risk-related studies of critical infrastructures, however, focus rather narrowly on the direct consequences, e.g. expressed by services not supplied or cost of nonsupplied services. Although these measures might serve as a proxy for the direct societal

Att följa ett barns upptäcktsfärd in i modersmålet är ett äventyr för föräldrarna, men också något som fängslat språkforskare i decennier. Barn i olika delar av världen uppvisar en förvånansvärd samstämmighet i inlärningsmönstren när det gäller ljud, joller och tidiga ordkombinationer. Språken hos små barn är faktiskt mera lika varandra än vad motsvarande språk är i vuxenversionen. Vad är det då

The aim with this thesis has been to increase the knowledge about nonionic microemulsions and how they behave with increasing temperature. I have studied Nonionic Microemulsions made from C12E5, water and oil, with predominally hexadecane as oil, but also with octane, decane, dodecane and tetradecane as oil. I have worked with microemulsions at fixed surfactant to oil volume ratio of 0.815:1 and

An introduction to the beginning of a health professional Bachelor project

In this paper, we give an overview of the background for, the ideas behind, and the challenges to be addressed in the project "Spatio-Temporal Filtering Methods for Enhancement and Separation of Speech Signals," which is funded by the Villum Foundation. The project aims at addressing the problem of enhancing and separating speech signals from noisy mixtures, a problem also known as the cocktail pa

For some time, directional antennas have been considered to solve connectivity and interference issues in wireless networks. Several scenarios have been presented and often the conclusions drawn are positive, showing increase in capacity. However, to date there has been no effort to assess a holistic picture of the benefit/cost tradeoff and previous work mainly concerns either link scheduling or a
