The Zumaya section, northern Spain, is a suitable candidate to define the Global Stratotype Section and Point for the base of the Selandian Stage (Palaeocene) because of its excellent accessibility, exposure and stratigraphic continuity. Uncertainties exist, however, with regard to the stratigraphic horizon where to place the Danian/Selandian (D/S) boundary. Five potential stratigraphic horizons (

Personlig varumärkning är ett koncept som innebär att varumärken och dess image till stor del identifieras med en person. Personliga varumärken kommer med stora fördelar, exempelvis att en djupare relation etableras mellan organisation och konsument, vilket kan vara svårt att uppnå för en mer opersonlig organisation. Däremot kommer det även med större risker, som att organisationen och personen ba

Bakgrund: Ventilator associerad pneumoni (VAP) är ett medicinskt tillstånd som innebär allvarliga konsekvenser för den drabbade intensivvårdspatienten, i form av hotad livskvalité och överhängande risk för morbiditet och mortalitet. Direkta konsekvenser såsom till exempel förlängd vårdtid innebär större kostnader för sjukvården och samhället därav är det av vikt att implementera effektiva interven

Virtual reality (VR) has dominated technology headlines in recent years with its ability to immerse users in a virtual world. This technology is changing the tourism industry dramatically. Previously, VR has been used mainly as a marketing tool to promote services and tourist destinations. But nowadays, VR is almost an essential technology, used in many tourism organizations to provide customized

The chapter focuses on European women who visited Jerusalem during the British Mandate period trying to prevent violence and build peace in civil society in times of violent conflict. Some of them were connected to the Anglican missionary schools, others were occasional visitors sent out by international peace organisations. Especially the informal role of women for peace building is emphasised. I

Alkyl glycosides were synthesised from starch and alcohols using Aspergillus oryzae a-amylase as catalyst. In the degradation of starch by a-amylase, the alcohols competed with water as glycosyl acceptors. In the reaction with methanol, methyl maltoside and methyl maltotrioside were the main alcoholysis products. Conversion of 45 g/1 starch in 30% methanol resulted in a product mixture containing

UV-B treatment of thylakoid membranes or fractions derived from them accelerates the first rise (Fo---Fi phase) of variable fluorescence and slows down the second (Fi---Fm) rise. This can be observed for all membrane fractions but to different extents. The grana fraction is affected more by the UV-B treatment than are the intact thylakoids and the stroma lamella fraction. An exogenous electron acc

A control system for pneumatic variable valve actuation has been designed, implemented and tested in a single cylinder test engine with valve actuators provided by Cargine Engineering AB. The design goal for the valve control system was to achieve valve lifts between 2 and 12 mm over an engine speed interval of 300 to 2500 rpm. The control system was developed using LabView and implemented on the

The ATP- and UTP-sensitive P2Y2 receptor which mediates both contractile and mitogenic effects has recently been shown to be upregulated in the synthetic phenotype of the vascular smooth muscle cell (VSMC). Using a competitive RT-PCR we demonstrate that the P2Y2 receptor mRNA is increased by fetal calf serum and other growth factors in a MAPKK-dependent way. This was confirmed at the functional le

A technology was developed to embed nm-sized metallic features in close vicinity to semiconductor heterostructures, which allows a direct integration of resonant tunneling diodes (RTD) inside the channel of permeable base transistor. A AlGaAs/InGaAs based RTD was grown by molecular beam epitaxy (MBE), with peak current density either 70 or 120 kA/cm². A fundamental oscillation frequency
