Field diagnostic techniques to determine nitrogen in maize

Terra Latinoamericana, 2021
Few technologies are available to quantify crop's nutritional status during their vegetative cycle, such as in maize. Semiquantitative alternatives could replace the laboratory foliar analysis's classical approach for measuring nitrogen (N) in maize (Zea

Somato-Psychic Pathway: a universal developmental trajectory linking somatic structural–functional integrity, autonomic regulation, and the emergence of mind

Frontiers in Integrative Neuroscience
The Somato-Psychic Pathway (SPP) is proposed as a universal ontogenetic developmental trajectory through which somatic structural–functional integrity and autonomic regulation shape the emergence and stability of the mind under both physiological and ...
