In the run-up to the Copenhagen climate summit, the USA announced an emissions reduction target of 17% by 2020 (relative to 2005), and the EU of 20% to 30% (relative to 1990). China offered a reduction target for the CO2-intensity of its economy, but rejects a legally binding commitment. We use the targets announced by the EU and the USA to analyze the potential gain for China if it were to ado...

Purpose. Recent studies have suggested that the age of peak freestyle swimming speed is reached earlier in life in women than in men. However, no study has investigated the age of peak swimming speed in other swimming styles such as butterfly. The aims of the present study were to investigate the age of peak swimming speed in elite male and female butterfly and freestyle swimmers at the nationa...

Abstract We analyze Very Large Telescope/UVES observations of the quasar SDSS J024221.87+004912.6. identify four absorption outflow systems: a C iv broad line (BAL) at v ≈ −18,000 km s −1 and three narrower low-ionization systems with centroid velocities ranging from –1200 to –3500 . These outflows show similar physical attributes [O iii ] studied by Liu et al. (2013). find that two are energet...

We report on the discovery of SPLUS J210428.01-004934.2, an ultra metal-poor (UMP) star first identified from narrow-band photometry Southern Photometric Local Universe Survey (S-PLUS) Data Release 1, in SDSS Stripe 82 region. Follow-up medium- and high-resolution spectroscopy (with Gemini South Magellan-Clay, respectively) confirmed effectiveness search for low-metallicity stars using S-PLUS p...

Autism Spectrum Disorder (ASD) is defined as a syndrome that interferes with neurodevelopment. Considered chronic disorder, it requires special care from mothers and may compromise their quality of life. This study aimed to evaluate the factors associated health-related life ASD children. cross-sectional, descriptive, analytical study. An instrument developed by authors was used assess mother's...

Large-scale machine tools for the manufacturing of large work pieces, e.g. blades, casings or gears for wind turbines, feature pose-dependent dynamic behavior. Small structural damping coefficients lead to long decay times for structural vibrations that have negative impacts on the production process. Typically, these vibrations are handled by increasing the stiffness of the structure by adding...
