Abstract Root growth in subsoils of Oxisols is often precluded because the roots of many crops are sensitive to soil acidity. This increases plant stress during dry periods when available soil water in the limed surface layers is exhausted. The low soil CEC and high rainfall in Central Brazil suggest that soluble calcium salts might leach below the plow layer and reduce soil acidity. To test this possibility, soil columns, simulating field profiles, were constructed in the laboratory and various ...

Fluid fluxes within subsurface reservoirs give rise to surface displacements, particularly over periods of a year or more. Observations of such deformation provide a powerful tool for mapping fluid migration within the Earth, providing new insights into reservoir dynamics. In this paper we use Interferometric Synthetic Aperture Radar (InSAR) range changes to infer subsurface fluid volume strain at the Coso geothermal field. Furthermore, we conduct a complete model assessment, using an iterative approach ...

A suite of compressional and shear phase arrival times (P , S , PP , PcP , SS , ScS , PKPab , PKPbc , PKPdf , SKSac) and two sets of differential times (SS −S410S, SS −S660S) are used to infer lateral variations in P and S velocity structure in the entire Earth (crust, mantle and core). Volumetric heterogeneity is parametrized by 22 depth layers, each of which is subdivided into a grid of cells. In addition to volumetric hetero-geneity, we determine topography on the major internal velocity discontinuities, station corrections, ...

We consider the efficient and accurate computation of Givens rotations. When f and g are positive real numbers, this simply amounts to computing the values of c = f /√ f 2 + g 2 , s = g /√ f 2 + g 2 , and r = √ f 2 + g 2 . This apparently trivial computation merits closer consideration for the following three reasons. First, while the definitions of c , s and r seem obvious in the case of two nonnegative arguments f and g , there is enough freedom of choice when one or more of f and g are negative, zero or complex that LAPACK ...

Mudrocks are very common rocks that when in contact with water can present considerable volume change and breakdown. The many factors interacting in the swelling phenomenon complicated the approach required to carry out the present work, which focuses on the impact of cyclic wetting and drying on swelling behavior of mudrocks.

The band edge states determine optical and electronic properties of semiconductor nano-structures which can be computed from an interior eigenproblem. We study the reliability and performance of state-of-the-art iterative eigensolvers on large quantum dots and wires, focusing on variants of preconditioned CG, Lanczos, and Davidson methods. One Davidson variant, the GD + k (Olsen) method, is identified to be as reliable as the commonly used preconditioned CG while consistently being between two and ...

A major cause of seismic attenuation in fluid-saturated rocks is the flow of the pore fluid induced by the passing wave. At sonic and ultrasonic frequencies, attenuation appears to be dominated by the local (pore-scale) flow between pores of different shapes and orientations. A simple squirt flow model is developed in which all of the parameters can be independently measured or estimated from measurements. The pore space of the rock is assumed to consist of stiff porosity and compliant (or soft) pores ...

There is a relative shortage of appropriate organs available for transplantation. The appropriate diagnosis of brain death, a suitable family approach and the maintenance of the deceased donor are fundamental in addressing this issue. The intensive care physician plays a key role in the maintenance of the deceased donor, thereby reducing losses and increasing the number of successful transplants.
