This study investigated the percentage of carbohydrate utilization than can be accounted for by glucose ingested during exercise performed after the ingestion of the potent lipolysis inhibitor Acipimox. Six healthy male volunteers exercised for 3 h on a treadmill at about 45% of their maximal oxygen uptake, 75 min after having ingested 250 mg of Acipimox. After 15-min adaptation to exercise, they ingested either glucose dissolved in water, 50 g at time 0 min and 25 g at time 60 and 120 min (glucose, G) or sweetened water (control, C). Naturally labelled [13C]glucose was used to follow the conversion of the ingested glucose to expired-air CO2. Acipimox inhibited lipolysis in a similar manner in both experimental conditions. This was reflected by an almost complete suppression of the exercise-induced increase in plasma free fatty acid and glycerol and by an almost constant rate of lipid oxidation. Total carbohydrate oxidation evaluated by indirect calorimetry, was similar in both experimental conditions [C, 182, (SEM 21); G, 194 (SEM 16) g.3 h-1], as was lipid oxidation [C, 57 (SEM 6); G, 61 (SEM 3) g.3 h-1]. Exogenous glucose oxidation during exercise G, calculated by the changes in 13C:12C ratio of expired air CO2, averaged 66 (SEM 5) g.3 h-1 (19% of the total energy requirement). Consequently, endogenous carbohydrate utilization was significantly smaller after glucose than after placebo ingestion: 128 (SEM 18) versus 182 (SEM 21) g.3 h-1, respectively (P < 0.05). Symptoms of intense fatigue and leg cramps observed with intake of sweet placebo were absent with glucose ingestion.(ABSTRACT TRUNCATED AT 250 WORDS) [less ▲]

Pot experiments were conducted in the laboratory with lime applications to decrease trace elements in Chinese cabbage produced on soils contaminated by trace ele- ments in the intensive periurban area in Chenggong County, Yunnan Province, China. Soil was an acidic loam developed from lacustrine-alluvial deposits. Results showed the following: (1) soil pH increased from 5.3 to 6.5, and acetic-acid-extractable trace-element contents and ratio of acetic-acid-extractable trace-element contents in treatments relative to those in the control (RRCT) decreased with increased rate of lime application. (2) Chinese cabbage more easily absorbed acetic-acid-extractable trace elements. Enrichment coefficients related to trace-element availability (AEC) of lead (Pb; mean: 3.3) and zinc (Zn; mean: 5.8) were stable, and the AEC of cadmium (Cd) was 1.8–2.0 with increased lime application rate. (3) Trace-element contents in Chinese cabbage decreased, and biomass of Chinese cabbage increased, with lime application rate. Trace-element contents in soil solution and acetic-acid-extractable trace-element contents can predict trace-element contents in Chinese cabbage, especially for soil solution. Lime quality and trace-element accumulation in Chinese cabbage should be taken into account when amendment is added to in situ soil contaminated with trace elements. [less ▲]

The available energy (AE), driving the turbulent fluxes of sensible heat and latent heat at the earth surface, was estimated at four partly complex coniferous forest sites across Europe (Tharandt, Germany; Ritten/Renon, Italy; Wetzstein, Germany; Norunda, Sweden). Existing data of net radiation were used as well as storage change rates calculated from temperature and humidity measurements to finally calculate the AE of all forest sites with uncertainty bounds. Data of the advection experiments MORE II (Tharandt) and ADVEX (Renon, Wetzstein, Norunda) served as the main basis. On-site data for referencing and cross-checking of the available energy were limited. Applied cross checks for net radiation (modelling, referencing to nearby stations and ratio of net radiation to global radiation) did not reveal relevant uncertainties. Heat storage of sensible heat J (H), latent heat J (E), heat storage of biomass J (veg) and heat storage due to photosynthesis J (C) were of minor importance during day but of some importance during night, where J (veg) turned out to be the most important one. Comparisons of calculated storage terms (J (E), J (H)) at different towers of one site showed good agreement indicating that storage change calculated at a single point is representative for the whole canopy at sites with moderate heterogeneity. The uncertainty in AE was assessed on the basis of literature values and the results of the applied cross checks for net radiation. The absolute mean uncertainty of AE was estimated to be between 41 and 52 W m(-2) (10-11 W m(-2) for the sum of the storage terms J and soil heat flux G) during mid-day (approximately 12% of AE). At night, the absolute mean uncertainty of AE varied from 20 to about 30 W m(-2) (approximately 6 W m(-2) for J plus G) resulting in large relative uncertainties as AE itself is small. An inspection of the energy balance showed an improvement of closure when storage terms were included and that the imbalance cannot be attributed to the uncertainties in AE alone. [less ▲]

The world is facing a historical increase in energy demand and energy consumption. Renewable energy sources are considered as a solution to both environmental issues and increasing energy demand, but present high variability and low predictability. Variability and uncertainty are familiar aspects of all power systems. However, the increase of the share of renewable sources leads to new needs in terms of flexible resources. These resources can be provided by four different means: 1. Dispachable power plants (i.e with ramp up and ramp down capabilities) 2. Storage systems, mainly in the form of pumping stations. 3. Grid interconnections between countries 4. Demand side management. The present work focuses on the high voltage transmission grid, and assesses the amount of technical flexibility available to balance the fluctuations of Variable Renewable Energy (VRE) sources. The model is based on a dynamic programming unit commitment algorithm (i.e. accounting for each individual power plant on the grid) and focuses more particularly on the flexibility potential of power plants and of energy storage. The selected time resolution is one hour. Residual load curves are established on the basis of actual consumption for the year 2012 and on different scenarios of solar and wind penetration. The method is applied to the case of Belgium, based on actual disaggregated power consumption curves throughout the year, and on the current power generation park. Due to the difficulty to assess the flexible resource available through interconnections, the Belgian grid is considered isolated. It should also be noted that this work does not address the voltage stability issue: it focuses on balancing issues only (i.e. time constants varying between minutes and days). Simulation results show the VRE penetration potential is higher than usually considered. Bottlenecks therefore seems to be related to improper or inefficient market mechanisms, unable to take full profit of the technical flexible resource available. [less ▲]

We report acoustic measurements of popping bubbles during the collapsing of aqueous foams. The sound pattern is analyzed using classical methods of statistical physics. It is found that membrane rupture concerns a wide variety of situations: small and large membranes at the air/foam interface. Avalanches of popping bubbles are put into evidence. Time durations in between successive pops seem to be distributed on a universal power law. [less ▲]

Introduction: Children’s quality of life evaluation has specific methodological aspects. Objective: To examine the psychometric properties of the Portuguese version of the Child Quality of Life Systemic Inventory (CQLSI), which is based on an innovative conceptual and methodological approach to quality of life self-assessment, namely by being interactive and playful, having a psychometry which operates several scores and allowing an analysis of each domain of life. Methods: 120 Portuguese children, from 8 to 12 years old. Results: Internal consistency of the four scores of the CQLSI (State, Goal, Rank and Gap) is satisfactory; all scores have their own specificity. Data show convergent validity. On the other hand, no satisfactory factorial structure was found. Conclusion: Feasibility and psychometric adequacy of the CQLSI Portuguese version seems demonstrated. [less ▲]

Aliskiren (Rasilez®), a direct renin inhibitor, is currently indicated for the treatment of essential hypertension, as monotherapy or in combination, especially with hydrochlorothiazide (Rasilez HCT®). It may also be use to obtain a more complete blockade of the renin-angiotensin-aldosterone system (RAAS) when it is associated with an angiotensin converting enzyme inhibitor (ACEI) (or an AT1 angiotensin receptor antagonist) (ARA). There is some room for agents that may be more efficacious in reducing the progression of diabetic nephropathy than ACEI or ARA. In this context, the dual blockade of RAAS most probably offers a better efficacy than the simple blockade, but also exposes to a higher risk. Should ongoing trials confirm the preliminary favourable results, aliskiren might reach a forefront position among the armamentarium now available to optimize the RAAS blockade. The present article will summarize advances concerning the biochemical effects of the specific mode of action of aliskiren, especially the potential interferences related to increased renin/pro-renin levels, as well as results of recent clinical trials, not only in hypertension, but also in the fields of diabetes, renal insufficiency and cardiology. The objectives and design of the landmark study ALTITUDE will also be briefly presented. [less ▲]
