The intangible nature of software means that traditional processes for managing product development are not sufficiently effective. This, in combination with the increasing share of software in technical products, has had the effect of making it difficult to identify improvement proposals for engineering processes in many cases. This thesis uses both qualitative and quantitative research methods t
A study was made of the damped oscillations in fibre length that are observed when isolated muscle fibres from the frog are released during the plateau of an isometric tetanus to shorten against a constant load (force clamp recording) near the isometric level (temperature, 1.0-11.0 C; initial sarcomere length, 2.25 m). 2. The oscillatory length changes of the whole fibre were associated with simil
Aims: In a population of middle-aged women a survey was carried out to ascertain the prevalence of mental symptoms and psychotropic drug use, and further to investigate whether severe mental symptoms are associated with social situation, alcohol consumption, smoking, and physical health. Methods: All women (n510,766) aged 50-59 years and living in the Lund area were invited to the WHILA study, a h
The dissertation deals with how fine-dressed stone can serve as a historical source material. The aim is to show how the working of stone can be used to study the organization of mason's during medieval ages in östergötland. The purpose has also been to put light on a historical source material threatened to disappear thorugh weathering.
This paper examines lip and jaw kinematics in the production of labial stop and fricative consonants where the duration of the oral closure/constriction is varied for linguistic purposes. The subjects were speakers of Japanese and Swedish, two languages that have a contrast between short and long consonants. Lip and jaw movements were recorded using a magnetometer system. Based on earlier work sho
Changes in the composition of carrot cell wall proteins were investigated, associating metabolic changes during long-term storage with changes in mechanical properties. Harvested carrots accumulate an antifreezing protein in their cell walls reaching a maximum level after 12 weeks of storage at 0°C, followed by a gradual decrease. During the same period of time, there is a decrease in the slicing
This study comprises a technical and economic comparison of three different processes for the production of fuel ethanol from pine. The processes were based on the same technical and economic assumptions. The main difference between the processes lies in the front end of each process, i.e. in the pretreatment of the raw material and in the hydrolysis of the hemicellulose and cellulose to sugars. T
The adsorption of monolayers of the pyridine-carboxylic acid monomers (isonicotinic acid, nicotinic acid, and picolinic acid) on rutile TiO2(1 1 0) has been studied by means of X-ray photoemission spectroscopy. An investigation of the O 1s spectra shows that the molecular carboxylic groups are deprotonated and, hence, that the molecules bind to the surface in a bidentate mode. Moreover, the bindin
Popular Abstract in Swedish Hjärtats skrifter är en undersökning av brevet som kommunikationsform under 1700-talet. Brevkulturen i 1700-talets Tyskland betraktas som ett av startskotten för vad som brukar kallas den moderna tiden. I denna studie granskas brevkulturens funktion och betydelse för det epistemiska skifte som äger rum under senare hälften av 1700-talet. Undersökningens utgångspunkt ärThis dissertation examines the correspondence of the 18th-century German authors Anna Louisa Karsch and Johann Wilhelm Ludwig Gleim. The main emphasis of the present study is to demonstrate how readings of Karsch's and Gleim's correspondence shed light on epistolary culture. Particular attention is paid to the notion of epistolary culture as a relatively unrestrained ?experimental setting? for bou
An investigation was undertaken to outline how microorganisms suggested for use in coal desulphurization are affected by compounds leached from coal. Three species of the genus Sulfolobus were studied. Sulfolobus acidocaldarius was seen to be affected by compounds leached from coal more negatively than Sulfolobus brierleyi and Sulfolobus solfataricus. It was observed that certain conditions during
Popular Abstract in Swedish Under den geologiska period som kallas kvartärtiden (de senaste 2,6 miljoner åren) har flera istider (glacialer) och mellanistider (interglacialer) avlöst varandra enligt ett mönster där glacialerna varar i ungefär 100000 år och mellanistiderna i ca 10000 år. Under istiderna täcktes stora landområden på norra halvklotet, bl.a. Skandinavien, av väldiga inlandsisar. Då deThe aim of this thesis was to reconstruct the Holocene vegetational and climatic development in the Sylarna-Storulvån area, western Jämtland, in the central Scandes Mountains. Temporal trends and fluctuations in the elevation and vegetational character of the tree-limit ecotone were studied mainly by means of pollen and plant macrofossil analysis of two lake sediment sequences (Lakes Stentjärn and
This study contributes to the discussion on the potential of the IPPC Directive to serve as a driver for eco-efficiency through the analysis of case studies of British, Finnish and Swedish dairy industries and the corresponding regulatory bodies. The signals given to the companies on the required improvements and the focus of the permitting process - on the manufacturing process rather than end-of
Alport syndrome (AS) is a type IV collagen hereditary disease characterized by progressive hematuric nephritis, hearing loss, and ocular changes. Mutations in the COL4A5 collagen gene are responsible for the more common X-linked dominant form of the disease characterized by much less severe disease in girls and women. A "European Community Alport Syndrome Concerted Action" (ECASCA) group was estab
Deoxyuridine 5'-triphosphate nucleotidohydrolase (dUTPase, E.C. 3.6.1.23) catalyzes the hydrolysis of dUTP to dUMP and pyrophosphate and is involved in nucleotide metabolism and DNA synthesis. A crystal of the recombinant E. coli enzyme, precipitated from polyethylene glycol mixtures in the presence of succinate at pH 4.2, was used to collect synchrotron diffraction data to 1.9 Å resolution, in sp
A transition to environmentally sustainable societies should involve a significant and comprehensive — strategic—change. Much of the promise of SEA is associated precisely with its perceived capacity to facilitate such a strategic transformation by influencing selected ‘strategic decisions’. This paper examines the potential effectiveness and limitations of such an approach in light of contemporar
