Abstract in UndeterminedNoise is typically conceived as being detrimental for cognitive performance. Contrary to this notion recent studies have found that auditory noise may in some cases improve cognition. Recent data and theories suggest that this beneficial effect of noise depends on several factors including the type of task being performed and noise levels. More importantly, whereas some gro
Popular Abstract in Swedish Det här är en studie av Wallace Stevens poetik och poesi med inriktning på 1930-talet, då hans poesi påverkades av en kraftig kulturell press på socialt engagemang och politisk användbarhet. Argumentet framställer hur olika men samverkande element i hans poetiska språk, som diktion, prosodi och metafor, under den här perioden utnyttjas för att skapa ett intryck av estetThis dissertation studies Wallace Stevens? ideas and practice of poetic language with a focus on the 1930s, an era in which Stevens persistently thematized a keenly felt pressure for the possible social involvement and political utility of poetic language. The argument suggests how mutually implicated elements of his poetry such as diction, prosody and metaphor are relied on to signify or enact ae
The strategic alignment between e-procurement applications and business strategy domains are in focus for this paper. This paper examines the functionality and value adding mechanisms of the following e-procurement applications: e-sourcing, e-tendering, e-MRO, web-based ERP, e-reversed auctions and e-informing. The e-procurement applications are then put in relation, based on value adding mechanis
Vehicular ad-hoc networks (VANETs) offer a large number of new potential applications. One of the envisioned applications is of course Internet access, which can be provided with the help of some roadside basestations. Many of the applications benefit from multi-hop relaying of information, thus requiring a routing protocol. Characteristics unique to VANETs (such as high mobility and the need for

The luminescence from single quantum dots has been studied. Single dot photoluminescence was studied under continuous as well as under pulsed excitation. Time-resolved studies revealed fast relaxations in quantum dots. The time resolved measurements were fitted with a set of rate equations. Blinking in the luminescence was observed on a few quantum dots. The polarization of the emission from singl
Popular Abstract in Swedish DNA kan ses som en negativ laddad polymer som samtidigt har grupper som vill undvika vatten och därför bildas den karakteristiska dubbelspiralen. DNA och ett ytaktiv ämne (tensid) som är positivt laddad, bildar olika komplex. Dessa komplex är mycket mer kompakta än DNA själv. I denna avhandling har vi undersökt DNA och DNA-tensid komplex på olika ytor. Vi har använt oliThe interfacial behavior of DNA and DNA-cationic surfactant has been studied. Particular attention was paid to the type of cationic surfactant and the DNA conformation (single or double stranded) as well as the DNA length. Adsorption of DNA-cationic surfactant complexes is determined by a delicate balance between the DNA-surface, cationic surfactant-surface, and cationic surfactant-DNA-solvent int
Många har berättat om sina möten med poeten och människan Gunnar Ekelöf (1907–1968). I den här boken har drygt trettio ögonvittnesskildringar samlats. Några av bidragen har tidigare varit tryckta i tidningar, memoarböcker, essäsamlingar och självbiografier. De resterande är (utanför en trängre krets) helt okända, och några texter är nyskrivna. Flertalet skildringar hänför sig till de två, tre sis
Approximate expressions of the first moment of the order statistics of standard extreme value distributions are proposed. We compare different previously given approximations with the exact values. The results show that the approximation given here fits the exact values better than previously given models.
Artikeln analyserar Strindbergs drama "Påsk" från rättsteologiska perspektiv: lagens teologiska bruk, lagens politiska bruk, nådens "politiska" bruk. Det mångtydiga och sammansatta betonas och relateras till Strindbergs användning av lutherskt ortodoxa, rosenianska resp. swedenborgska tankar.
The influence of foreign-language acquisition on adult brain structure remains mostly unexplored. Whilst several cross-sectional studies have led to further understanding of how language can affect brain structure, only a few longitudinal studies have been conducted. We measured the effects of language acquisition on behaviour and brain structure at the Swedish Armed Forces Language School in two
