This article outlines an experimental and numerical study on the effect of cement type, silica fume, w/c, age and moderate shift of temperature on self-desiccation and strength of concrete. For this purpose 81 sealed cylinders made of 9 concretes with w/c varying between 0.32 and 0.50, based on two types of Portland Cement, were manufactured. Five per cent silica fume was used in one third of the

Popular Abstract in Swedish För att en flercellig organism ska kunna fungera krävs det att alla celler har en förmåga att svara på och anpassa sig till förändringar i dess inre och yttre miljö. För att kunna uppfylla detta krav utnyttjar cellerna utnyttjar ett komplext nätverk av signaleringsvägar där många av cellens enzymer och andra proteiner ingår. Proteinkinas C (PKC) är en enzymfamilj som beProtein kinase C (PKC) is a serine/threonine kinase family with 10 identified isoforms. The contribution of PKC isoforms to cell growth and differentiation, with focus on neurite outgrowth, was investigated, using neuroblastoma and immortalised neural cells as model systems. In neuroblastoma cells one or several of the classical PKC isoforms are of importance for driving proliferation, protecting

Popular Abstract in Swedish Demens med Lewy bodies - en ny demenssjukdom Vid sidan av de klassiska demensformerna Alzheimers sjukdom, blodkärlsdemens och frontallobsdemens har forskargrupper från flera håll i världen på senare år funnit tecken på en ny demensform som man kallar ”demens med Lewy bodies (DLB)”. Sjukdomen bär drag av både Alzheimers och Parkinsons sjukdom och därför är forskare oeniDementia with Lewy bodies (DLB) is a dementia disorder, clinically characterized by fluctuating cognitive impairment, attention deficits, visual hallucinations, parkinsonism and other neuropsychiatric features. Sensitivity to neuroleptic medication is a common finding. In the present study 24% of 200 autopsied cases, within the Lund longitudinal prospective dementia study fulfilled the clinical di

This paper presents a highly parallelized MIMO signal detection algorithm targeting vector-based reconfigurable architectures. The detector achieves high data-level parallelism and near-ML performance by adopting a vector-architecture-friendly technique - parallel node perturbation. To further reduce the computational complexity, imbalanced node and successive partial node expansion schemes in con

We consider the problem of constructing linear precoders for quasi-stationary multiple-input multiple-output channels. We assume maximum-likelihood detection and the objective of the precoding is to maximize the minimum Euclidean distance of the signaling. Since the channel remains constant for some time, the precoding can be performed spatially as well as in time. As will be shown, the precoder d
