William Ford Robertson (1867-1923): his study of neuroglia.
THE PRESENCE of a supporting tissue within the central nervous system was first demonstrated by Keuffel in 1811,1 when he showed a definite meshwork left in crosssections of spinal cord after the nervous tissue had been brushed out. He interpreted this as representing prolongations of the pia mater. Arnold in 18452 and Virchow3 in the following year both described a granular ground substance wh...
متن کاملAscorbic Acid and the Formation of Collagen* by William Van B. Robertson and Barry Schwartz
The importance of ascorbic acid for the metabolism of connective tissue substances, especially collagen, has been established by numerous investigators, using morphologic criteria (1). However, there have been few biochemical studies of this function of ascorbic acid with the exception of the recent analyses of Elster (2) and Robertson (3), which demonstrated that the maintenance of preformed c...
متن کاملFriedmann-robertson-walker Cosmologies
Abstract. Electrodynamics for self-interacting scalar fields in spatially flat FriedmannRobertson-Walker space-times is studied. The corresponding one-loop field equation for the expectation value of the complex scalar field in the conformal vacuum is derived. For exponentially expanding universes, the equations for the Bogoliubov coefficients describing the coupling of the scalar field to grav...
متن کاملRobertson Intelligent States
Diagonalization of uncertainty matrix and minimization of Robertson inequality for n observables are considered. It is proved that for even n this relation is minimized in states which are eigenstates of n/2 independent complex linear combinations of the observables. In case of canonical observables this eigenvalue condition is also necessary. Such minimizing states are called Robertson intelli...
