A new passive subharmonic mixer topology is presented and compared to a previously published passive topology. The comparison is conducted using simulations at 30 GHz with a 90-nm CMOS design kit. The advantage of the new passive subharmonic mixer is that it only requires a differential local oscillator (LO) signal, compared to the previously published mixer that requires a quadrature LO signal. T
The present thesis involves a process evaluation of what occurred in the treat¬ment of seven young patients in institutional care diagnosed with schizophrenia: what happened in the encounters between staff and patients in a ward environ¬ment designed to provide constant care, and what facilitated or hindered rehabili¬tation efforts. The aim of the process presentation was to portray the treatment
Analysis of pollen and spore assemblages from both terrestrial and near-shore marine sediments in New Zealand reveal an instant and dramatic mass-kill of the land plants in close association with the Cretaceous-Tertiary boundary (KTB) event. The turnover in the palynoflora is followed by a recovery succession, the most prominent feature of which is an interval dominated by fern spores (fern spike)
Extending the product development process to also include the concurrent design of product and packaging is expected to increase efficiency and effectiveness in the development process. Apart from the obvious advantage of reducing the lead times of the development project, improving environmental impact by reducing the consumption of raw material due to the possibility of facilitating a "tailor ma
The objective of the seminar was to summarize, discuss, question and conclude the present state-of-the-art on prediction models for corrosion initiation due to chloride ingress in structures exposed to sea water and de-icing salts. Papers were presented on various topics. A test case was designed and the experts made predictions of chloride ingress for this well-defined case.
We explain autonomy with full-fledged reference to the complementaristic conception of language and its introspective capabilities. This field that we refer to is understood to belong to a wider epistemic category than that of (the received view of) semiotics as well as of systems science. It follows from the linguistic complementarity that autonomies (self-references; independencies) can never be
This thesis concerns the application of artificial neural network techniques to space weather physics. The networks applied include multi-layer error-backpropagation, radial basis function, and self-organized maps. Different parts in the solar-terrestrial chain are analysed with the emphasis on developing methods for real time predictions of geomagnetic activity. The neural networks are general mo
Popular Abstract in Swedish Den globala uppvärmningen av vår jord påverkar inte bara lufttemperaturen, utan även haven blir varmare. Dessutom förespås en ökning i nederbörd vilket kommer att göra havens ytvatten mindre salta. Temperaturförändringen och den ökade nederbörden kan leda till att skiktningen, den s.k. vertikala stratifieringen, som finns naturligt i haven blir skarpare och starkare. StIncreasing precipitation and surface water temperature due to global change may strengthen stratification in coastal regions, which could influence the behavior of dinoflagellate diel vertical migration (DVM). DVM is a behavioral mechanism by which dinoflagellates can access photosynthetically active radiation near the surface, and nutrients at depth. During this process, cells may need to cross b
This book discusses the theories, methods and perspectives of the scholarly biography. The point of departure is the continuously growing interest in biography as a genre over the last decade in history, literature and other fields of the humanities. In the first section of the anthology, “The Biographical Genre”, three articles highlight general tendencies and problems in biography writing. Adopt
Popular Abstract in Swedish Bindväven är kroppens stomme och fungerar som stödjevävnad i alla organ, som t ex lunga, samt i hud, ben mm. I bindväven finns olika typer av celler beroende på vilken slags vävnad det är. Den forskning som presenteras här berör fibrös bindväv. Denna är en mjuk och elastisk variant, som finns i t ex lungorna, i motsats till ben. De celler som dominerar i den fibrösa binFibrous connective tissue contains fibroblasts distributed in a complex network of extracellular matrix molecules, such as proteoglycans. The small proteoglycans biglycan and decorin are composed of a protein core substituted with two and one glycosaminoglycan (GAG) chain, respectively. Proteoglycan metabolism is regulated differently during several processes including inflammation and wound heali
Popular Abstract in Swedish Utvecklingen av säkrare och mer miljövänliga processer är en av de största utmaningarna som den kemiska industrin står inför. I det här sammanhanget är katalys i tvåfassystem, bestående av vatten och organiska lösningsmedel, av största intresse eftersom den möjliggör en enkel återvinning av katalysatorn samtidigt som den minskar skadliga utsläpp och kostnader för återviThe steric and electronic properties of eight water-soluble phosphines (1-8) were investigated by different methods. Phosphines 1-6 were tested as ligands in palladium catalysed hydroxycarbonylation of styrene. In line with the proposal that a ligand with low basicity should facilitate nucleophilic attack of water on the acyl complex, the electron rich {4 - [Bis(2 - diethylaminoethyl)] - aminobenz
