An Innovative Approach to Estimate Bioavailable Phosphorus in Agricultural Runoff Using Iron Oxide-Impregnated Paper The transport of bioavailable phosphorus (BAP) in agricultural runoff can accelerate the eutrophication of receiving water bodies. Bioavailable P is compri... AN Sharpley - 《Journal of ...
The authors present calculations which reveal the instability of flow in a free vortex for large rotation numbers. The obtained results are compared with the known ones [see M. Lessen, P. J. Singh and F. Paillet, J. Fluid Mech. 63, No. 4, 753–763 (1974; Zbl 0277.76041); K. Stewa...
Most sensory, cognitive and motor functions depend on the interactions of many neurons. In recent years, there has been rapid development and increasing use of technologies for recording from large numbers of neurons, either sequentially or simultaneously. A key question is what scientific insight can...
Defining stability of the colorectal epithelium by cumulative polyp counts is reasonable but depends on accurate detection of all polyps; it is not sufficient to find one adenoma when there are really five. Surveillance depends on risk and risk is reflected in cumulative polyp numbers. View article...

A 10-step solid-supported, enantioselective synthesis suitable for the rapid preparation of large numbers of diverse structural analogues of saframycin A is described. The synthetic route, which bears analogy to solid-phase peptide synthesis, involves the directed condensation of N-protected alpha-amino...

Ferroptotic cell death propagation in cell culture and in embryonic limbs exhibits several common properties. For example, their dependency on lipid peroxidation and cellular iron implies activation of shared ROS feedback loops that give rise to redox bistability. Supporting this notion, cell death pr...
In the time of dramatic loss of biodiversity worldwide, we did not find a significant decrease in species numbers over time when considering our entire study region in south-western Germany, neither for generalist nor specialist species. However, our results go in line with other large-scale ass...
moles per cell, corresponding to tenfold lower to sevenfold higher zinc than iron quotas13. In addition, marine cyanobacterial genomes comprise genes encoding typically zinc-requiring enzymes such as carbonic anhydrases that are essential for effective carbon fixation, and alkaline phosphatases for ...
