BACKGROUND: Pulsation in the flow velocity waveform in the umbilical vein is related to perinatal mortality but the flow velocity waveform in the fetal vein of Galen is normally even and without fluctuation. OBJECTIVES: To establish whether blood flow velocity pulsations in the vein of Galen in high-risk pregnancies are related to outcome. STUDY DESIGN: The vein of Galen was located by colour Dopp
The visual system of box jellyfish comprises a total of 24 eyes. These are of four types and each probably has a special function. To investigate this hypothesis the morphology and optics of the lesser eyes, the pit and slit eyes, were examined. The pit eyes hold one cell type only and are probably mere light meters. The slit eyes, comprising four cell types, are complex and highly asymmetric. The
Empirical research on the knowledge dynamics of biotechnology demonstrates a dual local-global knowledge flow pattern. The sector is characterised by strong spatial concentration around nodes of excellence that are interconnected through a global network. This requires a specification of the notion of proximity as a facilitator of learning processes which emphasises its multifaceted configuration.
Extensive microscopic molecular dynamics simulations have been performed to study the effects of short-chain alcohols, methanol and ethanol, on two different fully hydrated lipid bilayer systems (POPC and DPPC) in the fluid phase at 323 K. It is found that ethanol has a stronger effect on the structural properties of the membranes. In particular, the bilayers become more fluid and permeable: ethan
The effect of some amphipilic diblock-copolymers and comb-polymers on a balanced Winsor III microemulsion system is investigated with the quaternary system n-octyl-beta-D-glucoside/1-octanol/n-octane/D2O as basis system. The diblock-copolymers are polyethyleneoxide-co-polydodecenoxide (PEOx PEDODOy ) and polyethyleneoxide-co-polybutyleneoxide (PEO (x) PEBU (y) ), constituted of a straight chain hy
Popular Abstract in Swedish Jesaja 40-55 representerar en av Gamla testamentets höjdpunkter. Här ackumuleras bilderna av Gud som Israels konung, herde, fader, moder, skapare och försörjare. Det är en befriande, nyskapande och mäktig Gud som tilltalar ett modlöst, förtvivlat och krossat Israel. Dessa kapitel domineras av budskapet om tröst och räddning till den grad att bibelforskningen sammanfattaThe theology of Isaiah 40-55 has two seemingly contradictory aspects: the tension between the consolatory message of deliverance, and the harsh tone of accusation. In this part of the Book of Isaiah, YHWH's return to his people is demonstrated through the accumulation of declarations about YHWH's ability and his will to deliver the Israelites from the exile. At the same time, the Israelites are ex
When developing products, engineering designers often face the problem that their candidate for a technical solution, ranging from a concept to a detailed design, needs to be analyzed by a design analyst before it is approved or rejected and the engineering designer can continue his/her activities within the product development process. If engineering designers have to send every solution candidat
This disstertation is a study of the foundations of the early state of Lombard Italy, AD 568-774. The main issue of the work is the hypothetical integration of social sectors within the context of an early state, as opposed to alternative forms of integration. the possibilities of achieving this kind of integration is regarded as connected with the urban infrastructure. The chief analysis consist
The purpose of this article is to discuss how the aristocracy used space and landscape to strengthen their position in society and how this process developed from the Viking Age to the Middle Ages.
The article describes the methods used to determine Bronze Age peoples' use of the landscape in southern Scandinavia. The study is part of the Ystad Project, a large, interdisciplinary project with the aim of studying people and landscape from the advent of agriculture about 6000 years ago. Methods used included studies of archive data and maps, fieldwalking, and excavation. Results showed that th
This article addresses the causes and motives behind the Soviet decision to hand over the Vyshinskii note to the Swedish government in August 1947. In this note, signed by Deputy Foreign Minister Andrei Ia. Vyshinskii, it was falsely claimed that the whereabouts of the Swedish diplomat Raoul Wallenberg, who had been arrested by the Soviet military counterespionage death to the spies (Smersh) on 17
