Drip irrigation is presently widely recognized as the most efficient irrigation system that can be used in woody perennial crops. However, uncertainties exist on the more appropriate agronomic design to employ. Here, we summarized the research carried ou
Methylenimine has been identified as a potential prebiotic precursor of glycine, and it has been detected spectroscopically in interstellar clouds11,12. Methylenimine can also be produced from the decomposition of methyl azides4 and 2-azidoacetic acid13. Experimental study on the electronic spectrum ...

Water undergoes autoionization to a small extent; the ionization constant at 25°C is 1.008x10–14: 2H2O(l) ↔ H3O+(aq) + OH¯ Water reacts both as an acid and a base. With bases it reacts as an acid: NH3(aq) + H2O(l) ↔ NH4+(aq) + OH¯; and with acids it react...
Near infrared spectroscopy (NIRS) has been successfully used for non-invasive diagnosis of diseases and abnormalities where water spectral patterns are found to play an important role. The present study investigates water absorbance patterns indicative o
