This paper describes a VLSI implementation of V-BLAST detection for future multiple-input-multiple-output (MIMO) wireless communications. This design is implemented using a 0.35-μm 5-layer metal 3.3 V CMOS technology. For a 4-transmit and 4-receive antennas system using QPSK modulation scheme, a detecting throughput of 128 Mb/s can be achieved. Furthermore, it is shown that the implementation comp
Surface display in insect cells: Systems available for surface display that utilize bacterial phages are insufficient for displaying a number of eukaryotic proteins. By instead presenting proteins on the surface of eukaryotic cells or virus, some of these problems might be overcome. The baculovirus/insect cell system, which has a high expression rate and post-translational mashinery closely resemb
Commonly used definitions of plagiarism are misleading in that they seem to indicate that 1) plagiarism is associated with either intent or ignorance and that 2) the requirements for claiming ownership can be uniquely defined. However, the differences between coexisting socio-cultural contexts are large enough that a clear case of plagiarism in one context might even be considered as good practice
There are instruments that measure sexual function or sexual health for persons with RA, but since sexual health is a sensitive issue, the hypothesis is that it would be easier to have a standard questionnaire that could indicate the need for communication about sexual health issues instead of an extra questionnaire with more detailed questions on sexual health. The aim of the study is to find out

Distributed energy is not a new idea. However, advances in technology and rising awareness of major sustainability challenges are creating new opportunities. At one end of the spectrum, distributed energy refers to small and medium scale technologies that generate electricity (and heat). The term is often used to describe energy generated by units that are close to the location of use (either inde
Popular Abstract in English Antonie van Leeuwenhoek is known as the father of microbiology, because he made the first microscopic observation of bacteria in human history, published in 1683. For the naked human eyes, bacterial cells are too small to observe, and the development of microscopy techniques has since then been fundamental for examining bacterial cells. Recent advances in visualizing toCoiled coil proteins emerge as important determinants of bacterial cellular organization. Several such proteins display properties characteristic to metazoan intermediate filament (IF) proteins, and are therefore designated bacterial IF-like proteins. The best studied examples of the latter are crescentin in Caulobacter crescentus that determines the curved cell shape, and FilP (filament forming-p
REDD is one of the latest additions to a series of incentive-based mechanisms for reducing carbon emissions. Although international negotiations have not eliminated uncertainties regarding its social, economic and political implications, many developing and emerging countries have begun to engage in REDD. Peru, the country with the world’s fourth largest tropical forest area has good reason to par
Popular Abstract in Swedish Brist på fria radikaler kan ge artrit Fagocytiska celler i vårt immunförsvar producerar fria syre-radikaler för att eliminera fagocyterade (uppätna) mikroorganismer. Produktionen av dessa syre-radikaler sker med hjälp av ett enzymkomplex (NADPH oxidas) i cellmembranet samt i membranet på de fagosomer, innehållande mikroorganismer, som bildas i och med fagocytos. MännisThe aim of this thesis is to defend a novel mechanism that triggers arthritis susceptibility in both rats and mice through reduced production of reactive oxygen species (ROS), but also to introduce a novel model for chronic relapsing arthritis. Five papers are included, all of which employ animal models for rheumatoid arthritis and one that also uses animal models for multiple sclerosis. Paper I a
Popular Abstract in Swedish Den viktigaste frågan för många företag handlar om att trygga långsiktig och framgångsrik utveckling. Men hur säkerställer man ett företags framtid när efterfrågan förändras och kostnaderna för produktionen bara ökar? Hur hanterar man teknikutvecklingen och ändrade maktförhållanden i värdekedjan? Svaren på dessa frågor är ofta nytänkande, innovation och en stark kundoriThis thesis explores and describes strategic change towards increased customer orientation and innovation in the Swedish forest and paper packaging industry, an industry which has been subject to calls for new strategic directions for more than two decades. The large-scale and cost-efficient strategy, which has been the industry's hallmark, is in need of a more customer based and innovative emphas
Popular Abstract in Swedish Den föreliggande doktorsavhandlingen handlar om en kärnfysikalisk modell, kallad cranking-modellen, för beräkningar av egenskaper hos snabbt roterande atomkärnor. I modellen tvingas ett deformerat (icke-klotformat) kraftfält att rotera kring en axel genom masscentrum, samtidigt som partiklarna i atomkärnan, protonerna och neutronerna, rör sig i sina s.k. banor inuti denThe nuclear model for three dimensional cranking is extended to include a generalization of the Strutinski renormalization procedure from principal axis cranking to cranking about an tilted axis. A new computer code has been written for realistic, full-scale calculations within the three dimensional cranking model. The code is developed for calculations to produce output of high precision to allow
