OBJECT: By pursuing a policy of very early aneurysm treatment in neurosurgical centers, in-hospital rebleeds can be virtually eliminated. Nonetheless, as many as 15% of patients with aneurysm rupture suffer ultraearly rebleeding with high mortality rates, and these individuals are beyond the reach of even the most ambitious protocol for diagnosis and referral. Only drugs given immediately after th
Popular Abstract in Swedish Denna avhandling behandlar den process där man beräknar undervattensströmmar från ljud som reflekteras från en utsänd ljudpuls, precis som när en fladdermus bedömer omgivningen genom att lyssna på ekot. En ton skickas ut under en kort tid, och det Dopplerskift som uppkommer från rörliga föremål i vattnet kan sedan omsättas till vattenhastiget eller ström. Föremål som röThis thesis deals with the process of estimating underwater current from the backscattering signal transmitted from an ultrasonic transducer. The narrowband sinusoidal burst signal is Doppler-shifted due to the current, and this information is converted into current. The traditional mathematical model for this Doppler process is based on the assumption that the backscattering time signal is Gaussi
The first Scandinavian protocol for Ewing's sarcoma, SSG IV, resulted in a local control rate of 74% and 5-year metastasis-free survival (MFS) of 43%. The second protocol, SSG IX, was started in order to improve upon these results. It featured four chemotherapy cycles, each consisting of two courses of VAI (vincristine, doxorubicin, ifosfamide) alternating with one course of PAI (cisplatin, doxoru
Food quality affects growth, reproduction and community structure of zooplankton, and has implications for nutrient cycling and the transfer of energy and matter in aquatic food chains. While the issue of food quality in clear water lakes has received great recent attention, studies on food quality for zooplankton in humic lakes are scarce. Humic lakes are largely influenced by carbon of terrestri
Popular Abstract in English The main reason that we humans exist at all is because of photosynthesis. The food we eat, the oxygen we breath, most of the energy that warms our homes and powers our electronics are all products of photosynthesis. Over millions of years, plants, algae and some bacteria have developed biomachinery to harness solar energy and thrive. They do this by fixing carbon into cAlmost all life on Earth depends on the products of photosynthesis — the biochemical process whereby solar energy is stored as chemical-rich compounds. The energy of captured photons is transferred through a network of pigment-protein complexes towards the reaction center. The reaction center is responsible for trans-membrane charge separation, which generates a proton motive force which drives al

It is suggested that Proto-Nordic /r/ was velar or uvular and /z/ postdental. It is suggsted that the two pronunciations were preserved in different areas after the phonemic merger: postdental in central Sweden and Norway and velar/uvular in the south of Scandinavia. The idea that the velar /r/ was imported from France int he 17th or 18th century is rejected.
We study the solvability for a system of pseudodifferential operators. We will assume that the systems is of principal type, i.e., the principal symbol vanishes of first order on the kernel, and that the eigenvalue close to zero has constant multiplicity. We prove that local solvability is to condition (PSI) on the eigenvalues as in the scalar case. This condition rules out any sign changes from -
This thesis is concerned with spoken dialogue and the dynamic negotiation of meaning in English conversation. It serves two aims, one theoretical and the other practical. The theoretical aim is to further our understanding of the kinds of properties that influence the meaning of constructions in spoken dialogue and the role of underlying socio-cognitive processes. The practical aim is to compile a
The holotype (KUVP 1301) of Styxosaurus snowii—one of the earliest described elasmosaurid plesiosaurians—consists of a well-preserved cranium, mandible and articulated sequence of anterior–mid-series cervical vertebrae found in the lowermost Campanian strata of the Smoky Hill Chalk Member in the Niobrara Formation of Kansas, USA. This particular specimen has proven important for recent phylogenies
The anations of Pt(H2O)42+ and PtX(H2O)3+ (to trans-PtX(H2O)2) by X− = Cl−, Br−, I− and SCN− and the anation of trans-PtX2(H2O)2) by X− = Cl−, Br− and I− have been studied at 25 °C and 1.00 M perchlorate medium using both stopped-flow and conventional spectrophotometry. For large excess of X−, PtX42− is formed according to the mechanism in Figure 1. The results indicate an entering ligand order of
Popular Abstract in Swedish Det tillgängliga frekvensutrymmet i trådlösa kommunikationssystem, så som trådlösa datornätverk, är mycket begränsat. Detta tillsammans med den ökande trafikmängden skapar problem. Nya möjligheter finns dock i och med att det finns stora mängder bandbredd som är licensfri för användning. Ökad bandbredd möjliggör också ökad datahastighet. Det tillgängliga frekvensbandet The available bandwidth in wireless communication systems, such as the 802.11 family, is very limited. Together with the ever increasing data traffic, this causes problems. New possibilities are, however, available thanks to wide license-free bandwidth allocated at higher frequencies. Increased available bandwidth enables higher data rates in future radio systems that will be capable of Giga-bit/s
