Heavy metals have been accumulating in Brazilian soils, due to natural processes, such as atmospheric deposition, or human industrial activities.For certain heavy metals, when in high concentrations in the soil, there is no specific extractant to determine the availability of these elements in the soil.The objective of the present study was to eval
The paper features a computational fluid dynamics study southwestern aztec rug of a flapping NACA0015 hydrofoil moving with a combination of sinusoidal heaving and pitching.Several kinematic configurations are explored, varying sequentially pitch and heave amplitude, Strouhal number and phase angle, in an attempt to determine the influence of each
Abstract Paleoclimate records have been used to estimate the modern equilibrium climate sensitivity.However, this requires understanding how the feedbacks governing the climate response vary with the climate itself.Here we warm and cool a state-of-the-art climate model to simulate a continuum of climates ranging from a nearly ice-covered Snowball E
Abstract Background Abnormal health anxiety, also called hypochondriasis, has been successfully treated by cognitive behaviour therapy (CBT) in patients recruited from primary care, but only one pilot trial has been carried out among those attending secondary medical clinics where health anxiety is likely to be more common and have a greater impact
We have investigated the Auger decay in the temporal domain by applying a terahertz streaking light field.Xenon and krypton atoms were studied by implementing the free-electron laser in here Hamburg (FLASH) as well as a source of high-order harmonic radiation combined with terahertz pulses from an optical rectification source.The observed linewidth
