Web wrinkling is one of the more common web handling problems, caused by shear forces, resulting from in-plane misaligned rollers. Several analytical models have been derived, mainly based on the theory of beams or membranes and isotropic material properties. Paper is a highly anisotropic material but can be assumed orthotropic for thin structures as paper web. For this reason, an orthotropic plan

This study evaluates the costs associated with foraging for birds in a savannah woodland area in central Nigeria. Specifically, it looks at the following questions: 1) how does seasonal variability in food and water availability affect the value of resources to birds in dry environments? 2) Does proximity to water affect foraging decisions? What implication will this have in the management of sava

Five sets of gloves were tested on 3 hand models with 2 measuring system in order to ensure repeatability of results from the past and for the future. The other aims of the study were to compare the possible differences related to different number of measuring zones, and effect of temperature distribution over hand surface. The hand models had 2 (HF), 9 (H2) and 10 (H3) zones respectively. Models

This paper develops a procedure for estimating parameters of a cross-sectional stochastic frontier production function when the factors of production suffer from measurement errors. Specifically, we use Fuller's (1987) reliability ratio concept to develop an estimator for the model in Aigner et al (1977). Our Monte-Carlo simulation exercise illustrates the direction and the severity of bias in the

Svensk statsförvaltning genomgår, precis som privat sektor, ständigt förändringar och omstruktureringar, drivna av olika samhällstrender, ledarskapsidéer och politiska styrfilosofier. Vid dessa förändringar ställs verksamheten inför vägval som på olika sätt kan påverka dess förmåga att leva upp till omgivningens krav och förväntningar. Samtidigt finns inte utrymme för risktagande, eftersom förvalt

Piety and modernity is presented in Britain, Ireland, Scandinavia, Germany, and the Low Countries between 1780 and 1920. Emphasis is put on piety and politics, pious nationalism, pious enlightenment, piety and romanticism, Moravian and Evangelical inspiration, on communciations and mentalities, on gender aspects on pious language, assocatiational activities, minorities, as well as on the instrumen

Popular Abstract in Swedish Sekvensbaserade proteinveckningsmodeller utvecklas och testas på peptider med både betablad- och alfahelix-struktur, samt på små helix-proteiner. Modellernas potentialer är minimalistiska och baseras huvudsakligen på vätebindningar och effektiva hydrofobicitetskrafter. Den geometriska representationen av proteinkedjan är däremot detaljerad. Vi studerar det termodynamiskSequence-based models for protein folding are developed and tested on peptides with both alpha- and beta-structure, and on small three-helix-bundle proteins. The interaction potentials of the models are minimalistic and based mainly on hydrogen bonding and effective hydrophobicity forces. By contrast, the geometric representation of the protein chain is detailed. We explore the thermodynamic behav
