The overall objective of energy systems is to provide energy services, at affordable cost and without socially unacceptable side effects. However, energy related security, development, and environmental problems will continue to worsen if present trends in energy demand and the energy supply mix persist. Therefore, energy was a critical area of debate at the United Nations Conference on Environmen

The catalytic properties of cellobiose dehydrogenase (CDH) from the ascomycete fungus Myriococcum thermophilum adsorbed on a graphite electrode were investigated for a large variety of carbohydrate substrates. The effects of applied potential, pH and buffer composition were tested and optimized, and the most suitable conditions were used to evaluate the detection limit, linear range, and sensitivi

Per Olov Enquist's 1985 novel Nedstörtad ängel (Downfall) is, despite its modest proportions, one of the most poetically powerful and intriguing works in his oeuvre. It consists of a number of disparate stories which are presented as intertwined fragments. In this article I argue that the novel as a whole creates its meaning in the manner of a large-scale metaphor, in which the different stories s

BACKGROUND AND OBJECTIVE: Although hypertension is associated with increased cardiovascular risk, many individuals remain free from disease. This study is aimed to investigate whether this variation in individual susceptibility is associated with lung function. DESIGN: Population-based prospective cohort study. PARTICIPANTS: 'Men born in 1914', Malmo, Sweden. Subjects (n = 639) were examined and c

One common assumption in psychology is the impact of parenting and parent-child relationships on the child's adjustment throughout the life span. Studies have indicated that there are genetic influences on memories of parenting, but how these influences are mediated has not typically been investigated. A sample of 150 pairs of monozygotic and 176 pairs of dizygotic Swedish twin women reported on p

The basic organization of the catecholamine-containing neuronal systems and their axonal projections in the brain was initially worked out using classical histofluorescence techniques during the 1960s and 1970s. The introduction of more versatile immunohistochemical methods, along with a range of highly sensitive tract-tracing techniques, has provided a progressively more detailed picture, making

Playing a musical instrument demands extensive procedural, motor, and cognitive abilities, and early musical learning results in plastic reorganization of the developing brain. Even the adult brain has a considerable plasticity, and neuronal cortical connections can be remodeled by experience during one's lifetime. Current neuroimaging methods have demonstrated complex and widespread activation in

Aggressive angiomyxoma is a soft-tissue neoplasm with a predilection for the pelvic and perineal regions and a tendency to recur locally. Cytogenetic data on this tumor type are limited to five cases, three of which showed rearrangement of chromosomal bands 12q13-15. Molecular investigation of two of the tumors identified the HMGA2 gene as the target of the 12q rearrangements. However, the two pre

We consider transmission by a vector adder channel with two independent inputs and additive white Gaussian noise. Decisions on the channel output are made by individual decoders. A new metric for decoding in such a channel is proposed, which is a generalization of the correlation metric and is close to the optimal metric in some cases. Bounds on decoding error probability are given. A procedure fo

The sedimentary record from the Ugleelv Valley on central Jameson Land, East Greenland, adds new information about terrestrial palaeoenvironments and glaciations to the glacial history of the Scoresby Sund fjord area. A western extension of a coastal ice cap on Liverpool Land reached eastern Jameson Land during the early Scoresby Sund glaciation (approximate to the Saalian). During the following g

Growth of the smooth muscle cells in the rat portal vein was induced by a partial ligation of the vessel. The ligation caused an increase in the transmural pressure and segments of the portal vein were investigated 6 weeks after the ligation. The spontaneous contractile activity of the ligated veins was similar to that of the control veins. In the ligated vessels the active force at optimal length

We studied electrophysiological properties of single chemosensory neurons in the mouthparts of the spiny lobsters Panulirus argus and Panulirus interruptus to complement our growing understanding of the behavioral roles of mouthparts of decapod crustaceans. Food mixtures and 13 single compounds were used to characterize the response specificity, sensitivity, and time course of individual neurons i
