Objectives: To investigate whether postural stability and adaptation differed after a normal night of sleep, after 24 h (24 SDep) and 36 h (36 SDep) of sleep deprivation while subjected to repeated balance perturbations. Also, to determine whether there was any correlation between subjective alertness scores and objective posturographic measurements. Lastly, to investigate the effects of vision on

In the context of growing concerns over climate change and peak oil, biofuels for transport are attracting considerable support from the European Union (EU). However, the sustainability of biofuels is under increasing debate. Furthermore, the complexity of the biofuels industry (involving different resources and feedstock suppliers, different logistics providers and options, a range of technologie

Purpose To explore what theoretical lenses have been used to analyze and understand information sharing in supply chains. We elaborate on the predominant theories and discuss how they can be used to research different aspects of information sharing. Design/methodology/approach We carried out a structured literature review by using a combination of selected keywords to search for peer-reviewed art

We calculate the phase property of the reflection coefficient in two-terminal structures using a lattice tight-binding model. It is seen that, provided that there exist two coherent reflection paths, the reflection probability can be zero for certain electron energies. At these energies, the phase of the reflection coefficient shift abruptly by $pi$. Next, we study the reflection and transmissio

In the 2000s, Sweden experienced a veritable explosion of feminist performance. Although feminist actions, theatre, shows and performance existed previously, feminist events with a distinct performance approach have emerged strongly in the current decade. Feminist culture festivals are held in rapid succession, and feminist performance, dance and theatre occasionally attract broader audiences. Thi

Abstract. A well known trade-off effect with modelling is that when it is user friendly it becomes ambiguous and when it has a formal notation, that makes it unambiguous, it becomes less user friendly. A well known solution to this dilemma is to use models on various levels of formalism where the least formalized models are known to be more user friendly and the most formalized models are well sui

This paper describes the product life cycle and its implications for the requirements engineering process, and proposes a research agenda for increasing the understanding of market and product maturity implications on requirements engineering. A product life cycle comprises four stages of maturity: Introduction, Growth, Maturity and Decline. All products go through these four stages of maturity du

Det talas med jämna mellanrum om något som envist kallas “internetberoende”. Diskussionerna, som tycks blossa upp någon gång om året har en del gemensamma drag. Några sådana är exempelvis att de bygger på skrämselargument, att de ofta baseras på floskler och ovetenskap samt att de till synes med klockprecision sammanfaller med lanseringen av nya entreprenöriella behandlingsverksamheter som ska lös
