Reconstruction of Bi-Isotropic Material Parameters from Experimental Data

Time-varying wave propagation and time-harmonic wave propagation in biisotropic materials are reviewed and the connection between the formulations is established via the temporal Fourier transform. An alternative method to determine the dispersive properties of a bi-isotropic slab from sinusoidal scattering data at normal incidence is presented. A numerical example (realistic, synthetic scattering

Complexity, Cost Reduction and Productivity Improvement through History

History shows us that in the cost/performance ratio of any given product has decreased continuously. This may wrongly have led us to the conclusion that improvements can continue infinitely at the current pace. Our proposition is that we trust a mental picture that is not consistent with the future level of potential improvements in technology and business, which in turn has repercussions for soci

Cellbiologi

Boken går igenom de molekyler som bygger upp cellen och hur enzymer arbetar, cellens organeller, cellens olika mekanismer och funktioner. Molekylärbiologiska metoder beskrivs och till sist cellens energimetabolism och reglering av denna. Boken förankrar cellbiologin i verkligheten, dvs. låter läsaren förstå det direkta sambandet mellan synliga symtom hos en patient och de osynliga molekylära händ

Knowledge Management: an Open Systems Approach

Nowadays, organizations pursue their aims in a context of distributed collaboration, creating a need not only for supporting ICT systems, but for a hu-man-centred focus in which individual and group sense-making and learning are supported by appropriate toolsets. We argue that development of such toolsets re-quires an open systems approach. This paper discusses one example: non-competitive benchma

Polyurethane - occupational exposure, biomarkers and symptoms

Popular Abstract in Swedish Isocyanater kan orsaka arbetsrelaterad astma, rinit och ¨allergisk¨ lunginflammation. De mekanismer som ligger bakom initieringen av dessa tillstånd och relationerna mellan exponering och effekt är dock otillräckligt kända. Det vore värdefullt att kunna mäta exponering och risk med biologiska metoder. En patient, exponerad för upphettad polyuretan, hade metaboliter av 4Isocyanates may cause occupational asthma, rhinitis, and hypersensitivity pneumonitis. However, the mechanisms behind initiation of the disorders and the relations between exposure and effect are insufficiently elucidated. Means to biomonitor exposure and risk would be valuable. A case, exposed to heated polyurethane, displayed metabolites of 4,4'-dipheylmethane diisocyanate in blood and urine, an

Quality Enhancement for Mobile Learning in Higher Education

This chapter focuses mainly on quality and a frame of reference to understand M-learning dimension concerns as course design, learning design, and media design and content. Consistent layout and design, clear organization, and presentation of information, consistency, easy-to-use navigation, and aesthetically pleasing design and graphics are dimensions that also have to be taken into consideration

Should pregnant women actively train?

Background The aim of this review article is to examine the evidence in the literature with regard to the safety of exercise in pregnancy. Material and Methods A literature search revealed fourteen randomised controlled trials which were systematically reviewed. The outcome measures looked at were both short and long term consequences of training in healthy pregnant women. Results The methodo
