In fire safety engineering, information about the expected walking speed of occupants through smoke is one factor that is of great interest to the designer. However, despite the fact that research already in the 1970s demonstrated that people tend to evacuate through smoke, little research has been performed on the topic, and evidently there is a lack of data on walking speed in smoke. This has cr
Natural food webs are embedded in a variable environment, which causes population densities to fluctuate, despite a potential stable equilibrium. Population interactions as well as the characteristics of the environmental fluctuations determine the resulting population dynamics. Populations sensitive to the same kind of environmental disturbances will show correlated responses in their respective
This paper reports on an inquiry into the use of metadata, publishing formats, and markup in editor-managed open access journals. It builds on findings from a study of the document architectures of open access journals, conducted through a survey of 265 journal web sites and a qualitative, descriptive analysis of 4 journal web sites. The journals’ choices of publishing formats and the consistency
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
Kapitlet utgår ifrån den tidigare modernitetens manifestationer av Durkheims "organisk solidaritet", de former av Gemeinschaft som mest typiskt utvecklades i småstaden vid tiden för Gesellschafts genombrott, där de lyckades hålla samman i grunden splittrade kollektiv. Mot bakgrund av aktuell empiri diskuteras sedan konsekvenserna av dessa gemenskapers upplösnng för människor i vår egen tid. Dessa
Today we use products to shape our identity, by communicating to others who we are and what we want to be. Using products for communication of identity seems especially important for young adults. Persons with disabilities live with double identities. Sometimes it is important to be a person with a disability (e.g., someone in contact with health care and other welfare systems in society), while a
Popular Abstract in Swedish Stärkelsemikrosfärer undersökta i denna avhandling är avsedda för kontrollerad tillförsel av läkemedel som utförs i form av depåpreparat eller slow release-former. Stärkelsemikrosfär är en beredningsform anpassad för inkapsling av protein i terapeutiskt syfte. För att uppnå en kontrollerad frisättning kan stärkelsemikrosfärer täckas av poly (DL-lactide-co-glycolide) (PStarch microsphere is a dosage form suitable for the encapsulation of protein drugs. The starch microspheres investigated in this thesis are intended for release of the drug in a pre-designed way, or in controlled manner. For this purpose the starch microspheres can be coated by poly(DL-lactide-co-glycolide) (PLG) film, which is a release controlling. The term microsphere quality is complicated an

Background The plant respiratory chain contains several energy-dissipating enzymes, these being type II NAD(P)H dehydrogenases and the alternative oxidase, not present in mammals. The physiological functions of type II NAD(P)H dehydrogenases are largely unclear and little is known about their responses to stress. In this investigation, potato plants (Solanum tuberosum L., cv. Desiree) were sprayed
Popular Abstract in Swedish Under de senaste åren har det varit möjligt att skönja hur fenomenet eller begreppet varumärken har spridits från den traditionella marknadsföringsdiskursen och marknadsförare till varnliga konsumenter och deras vardagsdiskurs. Konsumenter kan därför förväntas besitta någon form av förståelse för hur märken som fenomen fungerar. Denna studie fokuserar på hur en sådan vaDuring the recent years the concept or phenomenon of brands and the importance ascribed to them by the traditional marketing discourse seems to have spread to the every day discourse of ordinary consumers. Consumers are therefore thought to posses some kind understanding of how brands as a phenomenon work. This study sets out to investigate how consumers construct such a brand understanding, and w
Several ligands based upon 2-substituted bicyclic[2.2.2]octane-2,6-diols (BODOLs) were synthesized and evaluated in two catalytic reactions: I) the Ti(IV)-mediated catecholborane asymmetric reduction of prochiral ketones and II) as catalysts in the asymmetric addition of diethylzinc to aromatic aldehydes. The ligands were prepared by baker's yeast mono-reduction of bicyclo[2.2.2]octane-2,6-dione,
Understanding consumer experiences of products is becoming increasingly important for producers acting on the global market. This paper presents a pilot study done as part of the development of a VIPET (Visual Internet Product Experience Tool), a future tool for remote user assessment of product experiences. The aim of the tool is to provide users with a convenient and intuitive approach to assess
