Humans are able to attentively discriminate number from 6 months of age. However, the age of the emergence of this ability at the pre-attentive stage of processing remains unclear. Event-related potentials (ERPs) were recorded in newborn human infants aged from 3 to 5 days. At 500-ms intervals, the infants were passively exposed to 200-ms sequences of four tones. Each tone could be either 1000 or

The most common loop in an industrial plant is a SISO-loop with a PI(D)controller. If the loop is affected by disturbances,these can be handled by adding a feedforward control action. In an industrial control system there are many measured signals, apart from those of the loop, available. The question we address in this article is how to select the feedforward variable out of the available measure

Recent critics of organizational learning and its normative offshoot the ‘learning organization’ have posited that conceptualisations of organizations based on knowledge and learning constitute a rhetorical device enabling elites to assert different forms of control through a new ‘normalising discourse’. The paper, whilst welcoming such critique, nevertheless asks whether it is adequate to dismiss

The major histocompatibility complex class I (MHC-I) has recently been shown not only to present antigens to the immune system but also to mediate transmembrane signaling, resulting in activation, inactivation, or apoptosis. Such signaling has been observed in both normal and malignant cells of the B and T cell lineage. Cross-linking of MHC-I on the pre-B- acute-lymphocytic cell line KM-3 induces

The pancreatic β-cell secretes insulin in response to elevated plasma glucose. This review applies an external bioenergetic critique to the central processes of glucose-stimulated insulin secretion, including glycolytic and mitochondrial metabolism, the cytosolic adenine nucleotide pool, and its interaction with plasma membrane ion channels. The control mechanisms responsible for the unique respon

A mean field feedback artificial neural network (ANN) algorithm is developed and explored for the set covering problem. A convenient encoding of the inequality constraints is achieved by means of a multilinear penalty function. An approximate energy minimum is obtained by iterating a set of mean field equations, in combination with annealing. The approach is numerically tested against a set of pub

The levels of different reactive species, especially those of nitric oxide and peroxynitrite, were determined in streptozotocin-induced diabetic rat tissues, before the development of histopathological damages. Significantly higher steady state free radical concentrations were found in the liver 3 weeks after the onset of diabetes compared to age-matched control groups. Increased nitric oxide leve

In pre-industrial society, choosing a marriage partner was a crucial process, and especially so for landowners. This study focuses on social aspects of mate selection in five rural parishes in southern Sweden between 1829 and 1894, using an individual-level database containing information on a large number of marriages and the social origins of the marrying couple regardless of whether they were b

We have investigated the reversibility in the shear-induced multi-lamellar vesicle (MLV) size during stepwise cycling of the shear rate by employing common rheometry, polarized light microscopy and rheo-optic techniques. We thus address the question whether there is a true MLV steady state, irrespective of history. The system studied, was the nonionic surfactant triethylene glycol decyl ether (C10

Sheet-metal forming involves a complex strain distribution over the part. The strains consist of tension, compression, and a mix of both. A geometry has been developed, the X-Die, in order to gain insight into the strain behavior of different materials. The X-Die enables strain paths far into the tension/compression region, thus creating the possibility to extend the experimental base both for def

In a corner of the Egyptian revolutionary drama, the fisherfolk of the northern Nile Delta have begun to organise. They suffer an indicative predicament. The two great lagoons of Borullus and Manzala have largely been enclosed by fish farms as the Mubarak regime sought to expand Egypt's aquaculture industry. On the other hand, the sea is threatening to submerge the ground on which the very same fi

I västvärlden använder vi dagligen plastprodukter och det är svårt att föreställa sig en tillvaro utan plast, som idag är oumbärliga över ett brett spektrum av applikationer. Resulterande problem inkluderar nedskräpning, mikroplaster och global uppvärmning som ett direkt resultat av den fossila råvaran, som dessutom inte är en förnybar resurs. Nya typer av material som kan ersätta den fossila plasFossil-based resources for plastic production is growingly being challenged by renewable material in applications such as wood-plastic composites. One company dedicated to contribute to this transition is Bio Fiber Tech AB (BFT) who have patented a novel treatment of the wood component for improved compatibility with the polymer matrix. This thesis was in collaboration with BFT with the aim to cha

An evaluative neutralisation process, whereby questionnaire items are phrased to be less evaluative, was used to create a new less socially desirable version of the social dominance orientation scale (SDO7). The main goal is to counteract the persistent floor effect which has affected the scale since its inception. The rationale behind the suggested correction is rooted with the problem of social

Fractions rich in indigestible carbohydrates, such as fructan and arabinoxylan, are obtained as by-products when ethanol, starch, and gluten are produced from wheat flour. Today, these fractions are used as animal feed. However, these components may have positive physiological effects in humans. In this study, the content of indigestible carbohydrates in distillers' grains and process streams from

Photo-Fenton oxidation was used for treatment of synthetic textile wastewater as stand alone treatment, as pre-treatment before aerobic biological treatment and as post-treatment after anaerobic biological treatment. The processes were compared with regards to decolorization, chemical oxygen demand (COD) reduction and chemical consumption. When applying photo-Fenton alone for treatment of Remazol
