Excited states in (196)AU, populated in the Pt-196(p,n) and (d,2n) reactions, were investigated by in-beam gamma -ray and conversion-electron spectroscopy. Two only weakly connected level structures, built on the 2(-) ground state (negative-parity level scheme) and on the 5(+) isomer at 84.7 keV (positive-parity level scheme), are observed. The point of main effort of the present work was the inve
We show that the undular stray light, diffusely scattered by the optical system of a synchrotron beamline, can play an important role in the formation of high-resolution resonant photoelectron (RPE) spectra. The influence of the stray light is mediated through the Stokes doubling effect, with the Lorentzian tail of the spectral function being replaced by a more complicated form. This effect is sho
Formation of calcium oxalate incrusts, scaling, may cause severe problems in the pulp and paper industry. Enzymatic degradation of oxalic acid provides a novel approach to eliminate the problems with calcium oxalate precipitation. The performance of two oxalate-degrading enzymes, oxalate oxidase from barley and oxalate decarboxylase from Aspergillus, was tested in model experiments with respect to
A general methodology for noise reduction and contrast enhancement in very noisy image data with low dynamic range is presented. Video footage recorded in very dim light is especially targeted. Smoothing kernels that automatically adapt to the local spatio-temporal intensity structure in the image sequences are constructed in order to preserve and enhance fine spatial detail and prevent motion blu
Popular Abstract in Swedish För att lungorna ska utvecklas normalt hos ett däggdjursfoster, måste lungorna vara vätskefyllda. Det har länge varit kännt att denna vätska produceras av lungorna själva, genom s k klorid-sekretion. Vid födelsen måste det nyfödda fostret börja andas och därför är det ytterst viktigt att lungorna snabbt töms på vätskan som fanns där under fosterutvecklingen. Detta sker Alveolar fluid clearance is driven by active absorption of Na+ across the alveolar epithelium. Development and hormonal regulation of alveolar fluid clearance over 1 hour was studied by instillation of a protein-containing, isosmolar fluid into lungs of fetal, newborn, and adult guinea pigs. After 1 hour, a sample of remaining alveolar fluid was collected and the change in protein concentration wa
Of the many ways hydrogen can be produced, this chapter focuses on biological hydrogen production 12 by thermophilic bacteria and archaea in dark fermentations. The thermophiles are held as promising candidates 13 for a cost-effective fermentation process, because of their relatively high yields and broad substrate palette. Yet 14 many challenges remain to be faced, including improving productivit
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
Lactic acid bacteria (LAB), including Lactococcus lactis, are abundant in nature. These bacteria convert carbohydrates into mainly lactate by a rather uncomplicated metabolism. An improved understanding of the physiological and genetical mechanisms involved in carbohydrate metabolism and its regulation will improve the industrial use of LAB. The aim of this study was to investigate the maltose an
When something is different: respectability and bodily ability in stories about polio In this thesis I study the relationship between people’s stories about polio and norms concerning respectability and ability. The purpose is to examine sense-making processes surrounding polio disease. This is done by studying how the ”normality” and ”deviation” is produced and negotiated in individual stories a
There are many benefits offered by integrated enterprise computer systems. There are a growing number of options available to obtain such management information system support. A major problem when selecting Enterprise Information Systems, in special ERP systems, is how to deal with the great diversity of options as well as the number of criteria used to evaluate each alternative. There is an impl
Popular Abstract in Swedish Katalytisk omvandling av enkla kolväten till mer användbara substanser m.h.a. homogena/lösliga komplex av övergångsmetaller är ett mycket viktigt ämnesområde inom metallorganisk kemi. För att förstå hur processen går till har ett stort antal modellföreningar syntetiserats genom åren där man har studerat hur kol-väte eller kol-kol bindningar kan brytas. Man bör notera atThe work presented in this thesis deals with metallacyclic late transition metal complexes, obtained by intramolecular Csp3-H activation, and the application of such compounds in catalysis. The new hemilabile P,O phosphines N-methyl-N-propionyl-2-(diphenylphosphino)benzylamine (DPPAM), o-(diphenylphosphino)benzoic acid ethyl ester (DPPES), o-(diphenylphosphino)benzoic acid methyl ether (DPPET) and
In this study we approach the recent decline in income inequality in Latin America from the perspective of structural change with a focus on the relative performance of the agricultural sector. Our focus is on the underlying forces implied by Kuznets (1965). We zoom in on the relative performance of agriculture in the development process and the rural-urban duality and pay particular attention to
Popular Abstract in Swedish I litteraturen kring marknadsföring av tjänster har det i flera sammanhang diskuterats hur tjänster baserade på kombinationer av kundmedverkan och teknologi kan erbjudas till kunden. Exempel som behandlats är bankers uttagsautomater, självbetjäning på bensinstationer och automatiska banktjänster över telefon. Innan man kan presentera sådana rekommendationer behövs det gThis doctoral thesis deals with consumers’ attitudes towards serving them-selves with machines rather than being served by personnel. Its aim is to contribute to the theory of perceived service quality by providing a better understanding of customers’ attitudes and preferences when using technology-based self-service. In addition to aspects of service dealt with by traditional service-quality rese
E. coli continues to be a popular host organism for production of recombinant proteins. To obtain a high volumetric productivity at the cultivation stage, it is important to achieve a high cell density and a high specific productivity per cell. In many fed-batch processes, the substrate feed rate eventually becomes limited by the oxygen transfer capacity of the bioreactor. While biomass can contin
Previous fracture is a well-documented risk factor for future fracture. The aim of this study was to quantify this risk on an international basis and to explore the relationship of this risk with age, sex, and bone mineral density (BMD). We studied 15259 men and 44902 women from 11 cohorts comprising EVOS/EPOS, OFELY, CaMos, Rochester, Sheffield, Rotterdam, Kuopio, DOES, Hiroshima, and two cohorts
Breast cancer is the most common cancer form among women in the Western world. Although treatment has improved during the last decades, there is still a significant proportion of the patients who are not cured. To further improve clinical outcome we need new treatment strategies, new prognostic markers, and new treatment predictive factors for personalized medicine.In this dissertation I have focu
ABSTRACT The present study describes topics related to music education, and the education of flautists, primarily on a professional level, covering a period from early 18th Century up to the early 21st Century within the French flute tradition. Further related areas of importance are concepts such as intuition, imitation, mimeses and maieutics and their relation to a flautist’s learning and teachi
The book contains editions and studies of texts produced by Swedish academics active at the University of Leipzig in the fifteenth century. Academic texts from the Middle Ages are difficult to digest; the editions, translations and studies presented in this book and its companion volumes make them as accessible to the modern reader as one can possibly ask.
We report on the status of the Baltic/Wadden Sea flyway Eider population based on trends in breeding and wintering numbers throughout the region, supplemented by changes in the sex ratio and proportion of young Eiders as monitored in the Danish hunting bag. At the flyway scale, total numbers of breeding pairs decreased by 48% during 2000-2009, after relatively stable breeding numbers in 1991-2000.
This paper takes inspiration from the field of bio-mimicry to suggest what a plant biosecurity system might look like if it was modelled on the human immune system. We suggest structural and institutional changes to current biosecurity systems that would facilitate adaptive preparation and response policies, focusing particularly on the Australian plant biosecurity system. By improving information
