Fångad i deckarens fälla
Arbetarförfattare skriver deckare och når en bred publik. Men man kan lika väl säga att de förvandlar sig till underhållningsförfattare. Kanske går de under för en borgerlig kultur på samma sätt som när modernismen blev viktigare än klassen i litteraturen i mitten av förra seklet. Vänstern måste bygga upp sina egna kulturella institutioner om dagens arbetarlitteratur ska vidareutvecklas. Magnus Ni
Amlodipin bättre än atenolol vid hypertoni. Förebygger mortalitet och kardiovaskulära händelser mer effektivt, visar ASCOT
Observation of vacancies in Ga1-xMnxAs with positron annihilation spectroscopy
Positron annihilation spectroscopy can be used to determine the role of vacancy defects in semiconductors, by identification and quantification of the vacancies and their chemical surroundings. We have studied 0.5-0.8 mum thick low temperature MBE GaMnAs layers with Mn content 0.5-5% and different As-2 partial pressures at growth. The Doppler broadening results show that the Ga vacancy concentrati
Neruons; regulators of CNS inflammation
Neurons have been neglected as cells with major immune regulatory function. Here, we present novel data demonstrating that neurons are highly immune competent and play crucial role in regulation of T cell response and CNS inflammation. Neurons induce proliferation of activated CD4+T cells via B7-CD28 and TGF-?1-TGF-?R signaling pathways with amplification of TCR signaling and increased phosphoryla
Psychological profile in patients with Stages I and II breast cancer: associations of psychological profile with tumor biological prognosticators.
We have earlier shown that breast cancer patients with moderately or well differentiated tumors seem to be able to inhibit stress evoked from anger in a successful manner, while those with poorer prognosis do not. We now report a study with an enlarged group of patients, investigating associations between tumor biological factors and psychological profile. 129 patients with Stages I and II breast
Molecular analysis of wild and domestic sheep questions current nomenclature and provides evidence for domestication from two different subspecies
Complete mitochondrial DNA (mtDNA) control regions (CR) were sequenced and analysed in order to investigate wild sheep taxonomy and the origin of domestic sheep (Ovis aries). The dataset for phylogenetic analyses includes 63 unique CR sequences from wild sheep of the mouflon (O. musimon, O. orientalis), urial (O. vignei), argali (O. ammon) and bighorn (O. canadensis) groups, and from domestic shee

Recording of foetal movements: a comparison of three methods
As decreased foetal movement (FM) may indicate impaired foetal health, FM recording has been suggested as a method of assessing foetal well-being. A non-intrusive, automated method of recording FM (FM-detector), was compared with maternal and ultrasonographic assessment of FMs in 24 women in the third trimester of pregnancy. The FM-detector detected a greater proportion of ultrasonographically rec
Spectral shaping of UWB signals for time-hopping impulse radio
This paper studies the design of signaling waveforms for time-hopping impulse radio (TH-IR) with limits on the power spectral density. Such restrictions are imposed by the spectral mask prescribed by frequency regulators for ultra-wideband (UWB) signals. The "conventional" TH-IR system with pulse-position modulation and time-hopping multiple access gives rise to spectral lines that either violate

A general search for new phenomena in ep scattering at HERA
A model-independent search for deviations from the Standard Model prediction is performed in e(+) p and e(-) p collisions at HERA using H1 data corresponding to an integrated luminosity of 117 pb(-1). For the first time all event topologies involving isolated electrons, photons, muons, neutrinos and jets with high transverse momenta are investigated in a single analysis. Events are assigned to exc
Unga arbetslösas ansikten : Identitet och subjektivitet i det svenska och danska samhället
Popular AbstractStudier om undomars arbetsmotivation och inställning till arbete fokuserar ofta på skolundomar, vilket kan ge idealiserade bilder eftersom dessa ungdomar ännu inte försökt ta sig in på arbetsmarknaden. Verica Stojanovics avhandling fokuserar emellertid på ”äldre” (20-29 åriga) svenska och danska ungdomar som varit arbetslösa i några månader eller mer och hunnit känna av hur det är My aim is to show how unemployed youth, in Sweden and Denmark, during the years 1992-1996, were coping with their situation as unemployed, by focusing on their motivation for work, their conception of work, and their alternative action. Swedish youth have for a number of decades lived with a labour market policy which has had full employment as a goal and included active measures. Danish youth hav
A distance measure tailored to tailbiting codes
The error-correcting capability of tailbiting codes generated by convolutional encoders is described. In order to obtain a description beyond what the minimum distance d min of the tailbiting code implies, the active tailbiting segment distance is introduced. The description of correctable error patterns via active distances leads to an upper bound on the decoding block error probability of tailbi
Is hippocampal volume affected by specialization for food hoarding in birds?
The hypothesis that spatial-memory specialization affects the size of the hippocampus has become widely accepted among scientists. The hypothesis comes from studies on birds primarily in two families, the Paridae (tits, titmice and chickadees) and the Corvidae (crows, nutcrackers, jays, etc.). Many species in these families store food and rely on spatial memory to relocate the cached items. The hi
Test Scheduling and Scan-Chain Division Under Power Constraint
An integrated technique for test scheduling and scan-chain division under power constraints is proposed in this paper. We demonstrate that optimal test time can be achieved for systems tested by an arbitrary number of tests per core using scan-chain division and we define an algorithm for it. The design of wrappers to allow different lengths of scan-chains per core is also outlined. We investigate
Analysis of heparan-sulphate chains and oligosaccharides from proliferating and quiescent fibroblasts. A proposed model for endoheparanase activity
Human skin fibroblasts in different growth states were incubated with [3H]glucosamine and/or Na(2)35SO4 and extracted with Triton X-100 for various periods of time. Free heparan-sulphate oligosaccharides and protein-bound heparan-sulphate chains were separated by chromatography on octyl-Sepharose and analyzed. A pool of endogenously produced oligosaccharides, present in the cultured cells and isol
