Poland has demanded that US troops be based on Polish soil in the wake of Russian war games which simulated a nuclear attack and invasion. Radek Sikorski,

i bought some very cheap soil from a dollar store,and there was a fungus in it. i actually ran a controlled test with it. dont get me wrong, not all of it is the same. i did not think it mattered but.

Just a quick shot I have taken of my 12L tank where I used JBL Manado as soil. I really like this gravel but although I rinsed it over 24 hours it still raised the GH and electric conductivity. Since I am still cycling my new tank ...

Russia's foreign minister said Thursday he was surprised by Poland's call for more U.S. troops on Polish soil in response to Moscow's assertiveness, a news agency reported. RIA Novosti quoted minister Sergei Lavrov as saying that the ...

I present a new set of tools for detection of intersections among tracks in 2-D Cartesian or geographic coordinates. These tools allow for evaluation of crossover errors at intersections, analysis of such crossover errors to determine appropriate linear models of systematic corrections for each track, and application of these corrections and further adjustments to data that completely eliminates crossover discrepancies from final 2-D data compilations. Unlike my older x_system tools, the new x2sys tools implement modern algorithms for detecting track intersections and are capable of reading a wide range of data file formats, including data files following the netCDF COARDS...

Advanced algorithms in parallel computing can be employed for a better understanding of groundwater flow fluids. Water flows in very heterogeneous geological media which contain complex structures. Decomposing these structures into approximately equivalent sub-structures for a load-balancing is a major challenge. This paper proposes and analyzes a new algorithm using finite element methods to simulate parallel flow fluid in such complex media. Fully parallel software is developed and numerical examples are presented to show the efficiency and robustness of the algorithm proposed.

This work is the first installment in a two-part series, and focuses on the development of a numerical PDE approach to price components of a Bermudan-style callable catastrophe (CAT) bond. The bond is based on two underlying stochastic variables; the PCS index which posts quarterly estimates of industry-wide hurricane losses, as well as a single-factor CIR interest rate model for the three-month LIBOR. The aggregate PCS index is analogous to losses claimed under traditional reinsurance in that it is used to specify a reinsurance layer. The proposed CAT bond model contains a Bermudan-style call feature designed to allow the reinsurer...

Mixtures of artificial soil (10, 30 and 50% w/w) were prepared by adding sewage sludge (contaminated with 200±13mgkg−1 Cu, 867±18mgkg−1 Zn, 7±0mgkg−1 Cd, 122±6mgkg−1 Pb, 74±2mgkg−1 Ni) to the fraction of infertile mineral soil. The effect of accelerated ageing of artificial soils on metal fractionation (assessed by sequential extractions), mobility (assessed by extraction with deionised water and using the Toxicity Leaching Procedure, TCLP), phyto-accessibility (diethylenetriamine pentaacetic acid, DTPA, extraction) and oral-accessibility (in vitro Physiologically Based Extraction Test, PBET) was simulated by exposing soils to alternate high (105°C) and low (−25°C) temperatures. Accelerated ageing affected the fractionation of contaminants metal-specifically and...
