The purpose of this paper is to dialogue, to stress and to reflect upon education at secondary school, rurality, and community processes within different state areas, and about the compliance of the right to education in rural environments. We will show different school experiences that display unique management approaches, as is the case of a rural alternating agricultural school located in the province of Corrientes (Argentine Republic), an Agricultural Family School (EFA). The chosen EFA represents an experience of community organization, facing the lack of possibilities of secondary education in the rural area. The process of formation and construction of the space of this particular school crystalizes and brings clues about the collective history and the arguments that accompany it. We found in the school space hints of social organization and construction of other ways "of making and being school". [ABSTRACT FROM AUTHOR]

This paper describes the determination and evaluation of the major and trace element composition (Al, As, Ba, Ca, Cd, Co, Cu, Fe, K, Mg, Mn, Na, Pb, Sr and Zn) of Sechium edule (Jacq) Swartz fruits collected from four different places of production in Corrientes province, Argentina. Element concentrations were determined by using inductively coupled plasma optical emission spectrometry (ICP OES) after microwave digestion. The accuracy was confirmed with standard reference material of spinach leaves (NIST, 1570a) and spiking tests. Principal component analysis (PCA), linear discriminant analysis (LDA), k-nearest neighbors (kNN), partial least square-discriminant analysis (PLS-DA) and support vector machine (SVM) were applied to the results for discriminating the geographical origin of S. edule fruits. Finally, the LDA method was found to perform best with up to 90% accuracy rate based on the following elements: Ca, Ba, Cu, Mn, Na, Sr, and Zn. [ABSTRACT FROM AUTHOR]

This paper presents a geological model of Corrientes province (Argentina) based on Bouguer gravity anomaly data, obtained in 2073 measurement points. To build the model, the IGMAS+ interactive program was used. Two areas of approximately 135,000km2 were modeled in this study. The selection of these areas was based on the sectors where the largest number of gravity anomaly measurements was made and other type of data was available to perform the parameterization (i.e, lithology profiles in boreholes, seismic profiles and audio-magnetotelluric AMT soundings). The initial geological configuration proposed was composed by four layers: basement, sediments (Paleozoic–Lower Cretaceous), basalts (Serra Geral Group, Lower Cretaceous) and post-basaltic sediments. The result shows a basement compartmentalized in structural blocks separated by large faults. The connection of Asunción and Río Grande Arches is confirmed along a structural high that crosses Corrientes province from SE to NW. The basaltic layer shows lateral changes in its thickness, due to faulting, almost disappearing on the NW of Corrientes. This structural configuration has a special hydrogeological importance because it produces the rise of the Guaraní Aquifer System sedimentary series near the surface and the intense fracture network makes this area prone to local recharge and regional discharge.

This paper presents a teacher training setting produced within the context of an educational innovation project which introduces an initial literacy proposal in public schools in the province of Corrientes. Although this training main target is the appropriation of a language educational proposal, the psychosocial processes which a teacher goes through every time he/she faces a change processes in his/her pedagogical practices have been taken into account.
