Instrumental errors of geodetic VLBI
A model of VLBI observables includes eeects of geometry, environment of signal propagation and delays in the data acquisition system itself. Imperfection of the model of instrumental eeects can be a considerable source of errors in the estimates of the targeted parameters. Two eeects: spurious signals in phase calibration and instrumental polarization are considered in details. Methods of their...

Modes of inheritance of errors of refraction.
Eighteen families in which both parents had refractions within the range of + 4 0 D to 4 0 D and axial lengths seen in emmetropia (22.3-26-0 mm) showed coefficients of correlation of the order 0 5 indicative of polygenic inheritance. Such coefficients were seen for axial length (0.407) and for the cornea (0-487), but not for the lens (which is known to be yoked to the axial length). No such coe...

15 صفحه اولErrors of Refraction and Their Sequele
In theory no doubt any existing refractive error should be found and treated, so that the individual may enjoy the most perfect optical conditions possible. But it must always be borne in mind that the eyes are only part of the living organism, dependent on the whole, deriving from it and adding to it. This may modify the position. A comfortable and efficient ocular mechanism depends on much mo...
