The objective of this article is to review the existing historiography on the Escuelas de Barriada (Rural Schools of Bizkaia Province, Basque Country), created and promoted by the Provincial Council of Bizkaia between 1920-1937, giving nuance to certain issues and providing new data on four aspects. The first of these is the question of instructional language. The use of Basque in the classroom was progressively reduced in favor of Spanish almost from the first moment and did not provoke opposition from teachers, even though many of them were Basque nationalists. Secondly, we provide an analysis of the initial curriculum, which presented a more pedagogical rather than ideological approach, oriented towards a teaching style that was more comprehensive than memory-based. This was especially appreciable in the areas of mathematics and geometry, where exclusionary political indoctrination was avoided, with content referring to both Basque and Spanish identity. Thirdly, we analyse the alleged use of books containing Basque nationalist political content in these schools, of which we have found no evidence. And finally, we offer an overview of the type of teachers that worked in these schools, including an analysis of their ideological profile: more than 90% of the faculty was composed of women, generally young, single, Basque-speaking, Catholic and ideologically sympathetic to Basque nationalism . The research focuses on the 1920-1930 period, when the Provincial Council of Bizkaia was governed by Monarchists and when the Dictatorship of Primo de Rivera began. This was the period when the original pro-Basque project of these schools was transformed. Some data and questions about the later era are also presented.

Dekkers and de Lang (1977) have discussed a practical method of realising differential phase contrast in a STEM. The method involves taking the difference signal from two semi-circular detectors placed symmetrically about the optic axis and subtending the same angle (2α) at the specimen as that of the cone of illumination. Such a system, or an obvious generalisation of it, namely a quadrant detector, has the characteristic of responding to the gradient of the phase of the specimen transmittance. In this paper we shall compare the performance of this type of system with that of a first moment detector (Waddell et al.1977).For a first moment detector the response function R(k) is of the form R(k) = ck where c is a constant, k is a position vector in the detector plane and the vector nature of R(k)indicates that two signals are produced. This type of system would produce an image signal given bywhere the specimen transmittance is given by a (r) exp (iϕ (r), r is a position vector in object space, ro the position of the probe, ⊛ represents a convolution integral and it has been assumed that we have a coherent probe, with a complex disturbance of the form b(r-ro) exp (iζ (r-ro)). Thus the image signal for a pure phase object imaged in a STEM using a first moment detector is b2 ⊛ ▽ø. Note that this puts no restrictions on the magnitude of the variation of the phase function, but does assume an infinite detector.
