To predict the effects of environmental change and nature management on the distribution of plant species, it is crucial to understand the mechanisms of plant niche differentiation and habitat specialization. The importance to habitat specialization of particular plant traits and requirement of the regenerative phase of the plants life has received scanty interest. Our experiments on seed germinat

A uniplanar-compact electromagnetic band-gap (UC-EBG) structure is implemented at 60 GHz on a conventional PTFE (polytetrafluoroethylene) substrate. The structure surrounds a stacked microstrip antenna with gridded parasitic patch. The UC-EBG implementation results in about 5 dB decrease in the antenna E-plane normalized radiation pattern for angles along the substrate. The measured antenna gain i

Bone mass in adolescents and young adults was studied with regard to its age-related change and its determinants. Methodological aspects of bone mass measurements and their ability to predict future fractures were investigated. Bone mineral content (BMC) and bone mineral density (BMD) were assessed by the Single Photon Absorptiometry (SPA) and Dual Energy X-ray Absorptiometry (DXA) techniques. We

Nuclear quadrupole resonance (NQR) is a solid-state radio frequency spectroscopic technique that can be used to detect the presence of quadrupolar nuclei, that are prevalent in many narcotics, drugs, and explosive materials. Similar to other modern spectroscopic techniques, such as nuclear magnetic resonance, and Raman spectroscopy, NQR also relies heavily on statistical signal processing systems

This chapter describes small-scale reforming for on-site production of hydrogen. By small scale is meant a production rate higher than 50Nm3h-1. First, an overview of the reformer technology and feedstock options is given and hydrogen purity issues are discussed. Second, examples of suppliers and cost trends are presented. Finally, research related to progress in materials, development of more rob

Transaktionsanalytisk psykoterapi - Tre metoder som beskriver en transaktionsanalytisk gruppterapi Avhandlingen är baserad på en ett årig Transaktionsanalytisk gruppterapi. Transaktionsana-lysen (TA) är en integrerad, relationell psykodynamisk terapi med rötter i den humanistiska psykologin.

Abstract in UndeterminedWhy should one hold that the world is a world of tropes? Or, more generally: How do we justify our ontological conclusions? It seems clear that the only evidence at our disposal must belong to appearances. For a realist, however, it is unreasonable to think that our conceptualisation of reality will reveal to us reality as it is independently of how it seems. You simply can

This chapter describes various kinds of artificial light sources of interest to the photobiologist (natural light is described in separate chapters), starting with incandescent lamps and their properties, and continuing with gas discharge lamps, flashlamps, light-emitting diodes, and lasers. After a section on light filters, the chapter concludes with a treatment of monochromators, in which the mo

Product alternatives suggested by a generative design system often need to be evaluated on qualitative criteria. This evaluation necessitates that several feasible solutions which fulfill all technical constraints can be proposed to the user of the system. Also, as concept development is an iterative process, it is important that these solutions are generated quickly; i.e., the system must have a
