Physical, chemical, and biological processes create maintain the critical zone (CZ). In weathered crystalline rocks, these occur over 10–100 s of meters transform bedrock into soil. The CZ provides pore space flow paths for groundwater, supplies nutrients ecosystems, foundation life. Vegetation in aboveground depends on components actively mediates Earth system like evapotranspiration, nutrient...

(31)P Nuclear Magnetic Resonance (NMR) was assessed to investigate the phosphorus-containing compounds present in the tissues of the scleractinian coral Stylophora pistillata as well as of cultured zooxanthellae (CZ). Results showed that phosphorus-containing compounds observed in CZ were mainly phosphate and phosphate esters. Phosphate accounted for 19 ± 2% of the total phosphorus compounds ob...

Let b and c be fixed coprime odd positive integers with min{b, c} > 1. In this paper, a classification of all positive integer solutions (x, y, z) of the equation 2 (x) + b (y) = c (z) is given. Further, by an elementary approach, we prove that if c = b + 2, then the equation has only the positive integer solution (x, y, z) = (1,1, 1), except for (b, x, y, z) = (89,13,1, 2) and (2 (r) - 1, r + ...

The determination of propulsive abutment pressure and deformation characteristics roadway surrounding rock mass in top-coal caving mining is great significance for further research on stress, support equipment selection. This paper adopts the method combining theoretical analysis field test, taking Helin coal mine j7401 working face as object. relationship between revealed by monitoring stress ...

Experience in setting up a workflow from scanned images of mathematical writings into a fully fledged mathematical library is described on the example of the project Czech Digital Mathematics Library DML-CZ. An overview of the whole process is given, with detailed description of production steps involving scanned image processing and optical character recognition. Experience gained, lessons lea...

Taking the 14,030 panel of Zhaogu No. 2 coal mine as its research object, this paper studies evolution characteristics developing height, propagation track and caving arch shape water-flowing fractures under influence thick alluvium by utilizing a physical experiment, theoretical analysis field investigation. The results show that height limit span fracture zone experience four stages, which in...

We previously characterized 1-ethyl-2-benzimidazolinone (1-EBIO), as well as the clinically useful benzoxazoles, chlorzoxazone (CZ), and zoxazolamine (ZOX), as pharmacological activators of the intermediate-conductance Ca(2+)-activated K(+) channel, hIK1. The mechanism of activation of hIK1, as well as the highly homologous small-conductance, Ca(2+)-dependent K(+) channel, rSK2, was determined ...
