A key premise of the heuristics-and-biases program is that heuristics are “quite useful.” Let us now pay more than lip service to this premise, and analyse the environmental structures that make heuristics more or less useful. Let us also strike from the long list of biases those phenomena that are not biases and explore to what degree those that remain are adaptive or can be understood as by-prod

I denna artikel görs en genomgång av tillverkning och användning av självkompakterande betong. För detta ändamål beskrivs de krav som ställs vid tillverkningen samt ges några tillämpningar, såsom broar, tunnlar och höghus.

Seediq is an Austronesian language spoken in Taiwan. It has several characteristics which are typologically unusual but typical for Austronesian languages. VOS word order, subject-focus (i.e. a multipolar voice distinction which does not imply valency reduction) and cliticisation of subject pronouns. This dissertation comprises a surface description of the grammar of the language presented in the

OBJECTIVE: Serum and glucocorticoid regulated kinase 1 (SGK1) expression is increased by aldosterone and is a key regulator of the amiloride-sensitive sodium channel (ENaC) in the distal nephron. We have previously shown that two SNPs in SGK1 (rs1057293 and rs1743966) are associated with blood pressure variation and blood pressure progression in the general population. Therefore, we tested the ass

Intense continua of electromagnetic radiation of very brief duration are formed in the interaction of focused ultra-short terawatt laser pulses with matter. Two different kinds of experiments, which have been performed utilizing the Lund 10 Hz titanium-doped sapphire terawatt laser system are being described, where visible radiation and X-rays, respectively, have been generated. Focusing into wate

Objective. Assessment of disease activity in vasculitis can be achieved using the BVAS, a clinical checklist of relevant symptoms, signs and features of active disease. The aim of this study was to revalidate the BVAS version 3 (BVAS v. 3) in a cohort of patients with systemic vasculitis. Methods. A total of 238 patients with vasculitis from seven countries in Europe were evaluated at a single tim

The meniscus is a critical tissue in the healthy knee joint because of its shock absorption and load distribution properties. Meniscal damage is a frequent finding on MRI of the osteoarthritis (OA) knee. The damage appears as horizontal, flap, or complex tears; meniscal maceration; or destruction. Asymptomatic meniscal lesions are common incidental findings on knee MRI of the middle-aged or older

Objectives. The aim of this study was to investigate the occurrence and significance of hand deformities during the first 10 years of RA. Methods. One hundred and eighty-three early RA patients were included in the study during 1985-89. Mean +/- s.d. of age at onset was 51.4 +/- 12.4 years, and mean duration of symptoms before inclusion 12 +/- 7 months; 64% were women. The patients were followed a

In the political and medial discourse of the 1930s the contract-work system (stat/ar/ systemet) was depicted as a relic of pre-modern society and contract-workers (statare) as the highly exploited lower class with no legal rights, low incomes, miserable housing conditions and a chaotic family life. This picture has dominated Swedish social history ever since, and the main argument of this article

In this work extensions to principal component analysis (PCA) for wastewater treatment (WWT) process monitoring are discussed. Conventional PCA has some limitations when used for WWT monitoring. Firstly, PCA assumes that data are stationary, which is normally not the case in WWT monitoring. Secondly, PCA is most suitable for monitoring data that display events in one time-scale. However, in WWT op

The antiproliferative activity, and the capability of priming of glycosaminoglycan chains, of two series of peracetylated mono- and bis-xylosylated dihydroxynaphthalenes have been investigated for normal HFL-1 cells, as well as transformed T24 cells, and compared to the unprotected analogs. Our data show increased antiproliferative activity upon peracetylation, but a loss of selectivity towards T2
