Abstract in UndeterminedIn today's technology generations, e.g. 90 and 65 nm, the static power consumption becomes a major contributor to the total power consumption. This paper focuses on the arithmetic level and shows a methodology for a substantial reduction of the static power consumption. Simulations are done in a typical 130 nm technology. Based on the simulation results, the static power in
Enzyme-based amperometric biosensors have been developed and characterized in flow systems for a variety of analytes such as [beta]-N-oxalyl-[alfa],[beta]-diamionpropionic acid ([beta]-ODAP), L-glutamate, glucose, lactate, and sucrose, that have food analysis relevance. The principle of enzyme "wiring" using polymeric mediators poly(1-vinylimidazole) {(Os-4, 4' dimethylbipyridyl)2Cl3+/2+} and poly
The mufti-layer dynamic soil chemistry SAFE model was used to study the dynamics of recovery in the F1 catchment at Lake Gardsjon, Sweden. The influence of (F) sulphate adsorption, and (2) changes in marine deposition, oil model predictions of recovery was studied. Sulphate adsorption/desorption in SAFE is modeled by all isotherm in which sulphate adsorption is dependent oil both the sulphate conc
Acute ethanol exposure stimulated serotonin2 receptor signalling in cultured astrocytes. Pretreatment with the protein kinase C inhibitor H7 significantly increased the ethanol-induced potentiation of [3H]-inositol phosphates accumulation. The increase could be explained by an augmented activation of phospholipase C. The results indicate a role of PKC for the modulation of ethanol effects on cellu
The effects of medetomidine, a novel antifouling candidate, on the burrowing bivalve Abra nitida were studied. The burrowing behaviour, sediment reworking activity and faeces production were assessed after 24 h exposure of A. nitida to sublethal concentrations of medetomidine. Medetomidine caused a significant decrease in the burrowing response and in the sediment reworking activity. The median ef
Objective: The authors describe personality development and disorders in relation to symptoms of attention deficit hyperactivity disorder (ADHD) and autism spectrum disorders. Method: Consecutive adults referred for neuropsychiatric investigation (N=240) were assessed for current and lifetime ADHD and autism spectrum disorders and completed the Temperament and Character Inventory. In a subgroup of
During translation, the ribosome and several of its constituent proteins undergo structural transitions between different functional states. Protein L12, present in four copies in prokaryotic ribosomes, forms a flexible "stalk" with key functions in factor-dependent GTP hydrolysis during translocation. Here we have used heteronuclear NMR spectroscopy to characterize L12 conformation and dynamics i
Genus-level relative frequency changes, based on scolecodont data, show that the polychaete faunas went through dramatic turnovers during the Llandovery-Wenlock Ireviken Event on Gotland. In addition several taxa show range ends (FADs and LADs) and gaps in this interval; at least 20% of the lineages disappeared or became extinct during the event. Datum points 2 and 4 seem to have been particularly
Objective: To validate self-reported information on weight and height in an adult population and to find a useful algorithm to assess the prevalence of obesity based on self-reported information. Research Methods and Procedures: This was a crosssectional survey consisting of 1703 participants (860 men and 843 women, 30 to 75 years old) conducted in the community of Vara, Sweden, from 2001 to 2003.
During forward flight, a bird's body generates drag that tends to decelerate its speed. By flapping its wings, or by converting potential energy into work if gliding, the bird produces both lift and thrust to balance the pull of gravity and drag. In flight mechanics, a dimensionless number, the body drag coefficient (C-D,C-par), describes the magnitude of the drag caused by the body. The drag coef
Both native Trametes hirsuta laccase and the same laccase modified with palmytic chains to turn it more hydrophobic were prepared and studied with cyclic voltammetry and Raman spectroscopy. Native laccase immobilized in the monoolein cubic phase was characterized with resonance Raman spectroscopy, which demonstrated that the structure at the "blue" copper site of the protein remained intact. The d
A sample of 209 children was followed longitudinally to examine the impact of growing perspective-taking skills on positive and negative emotionality in middle and late childhood. Perspective-taking skills were assessed through interviews. Teachers rated children's emotional reactivity and capacity to regain a neutral state following emotional arousal. Analyses of contemporaneous data revealed tha
The Global Land-Atmosphere Climate Experiment-Coupled Model Intercomparison Project phase 5 (GLACE-CMIP5) is a multimodel experiment investigating the impact of soil moisture-climate feedbacks in CMIP5 projections. We present here first GLACE-CMIP5 results based on five Earth System Models, focusing on impacts of projected changes in regional soil moisture dryness (mostly increases) on late 21st c
We examined the effects of 50-Hz magnetic fields in the range of flux densities relevant to our current environmental exposures on action potential (AP), after-hyperpolarization potential (AHP) and neuronal excitability in neurons of land snails, Helix aspersa. It was shown that when the neurons were exposed to magnetic field at the various flux densities, marked changes in neuronal excitability,
Colour polymorphic species with extensive ranges often exhibit large-scale geographic patterns of morph frequency variation. Because colour polymorphism is associated with correlated differences in multiple traits, such as thermal performance, a likely proximate explanation for such patterns is morph-specific responses to temperature variation. The colour polymorphic Blue-tailed damselfly Ischnura
A systematic review and a meta-analysis were performed to quantify the accumulated information from genetic association studies investigating the impact of the CYP4F2 rs2108622 (p.V433M) polymorphism on coumarin dose requirement. An additional aim was to explore the contribution of the CYP4F2 variant in comparison with, as well as after stratification for, the VKORC1 and CYP2C9 variants. Thirty st
Background: Soils contain the largest stock of organic carbon (C) in terrestrial ecosystems and changes in soil C stocks may significantly affect atmospheric CO2. A significant part of soil C is present in cultivated soils that occupy about 35 % of the global land surface. Agricultural intensification has led to practices that may decrease soil organic carbon (SOC), and agricultural management has
A dynamic coupled biogeochemical-ecological model was used to simulate the effects of nitrogen deposition and climate change on plant communities at three forest sites in France. The three sites had different forest covers (sessile oak, Norway spruce and silver fir), three nitrogen loads ranging from relatively low to high, different climatic regions and different soil types. Both the availability
