    New possibilities of remote sensing by means of satellites to do research on natural resources are reported. These images make it possible to carry out integrated studies of natural resources in the shortest time possible and with small investments. Various maps and a complete description of each are included. With the use of these satellites, scientists can hopefully plan development projects at the national level

    Navigating the Terrain of Third Space: Tensions with/in Relationships in School-University Partnerships

    Using theoretical conceptions of third space and hybrid teacher education, we engaged in a collaborative self-study of our practices as university-based teacher educators working in student teaching partnership settings. We sought to understand the ways in which the hybrid teacher educator fosters and mediates relationships to work towards a collective third space. In this article, we describe the nature of relationships in our work, the tensions wrought by complexities of these relationships, and ways we negotiated tensions in order to foster relationships that productively mediated processes of teacher education. In addition, we propose a framework for moving beyond traditional notions of oppositional triadic relationships of student teacher, mentor teacher, and supervisor in recognition of complex social interactions in the third space

    LDA+DMFT Approach to Magnetocrystalline Anisotropy of Strong Magnets

    The new challenges posed by the need of finding strong rare-earth free magnets demand methods that can predict magnetization and magnetocrystalline anisotropy energy (MAE). We argue that correlated electron effects, which are normally underestimated in band structure calculations, play a crucial role in the development of the orbital component of the magnetic moments. Because magnetic anisotropy arises from this orbital component, the ability to include correlation effects has profound consequences on our predictive power of the MAE of strong magnets. Here we show that incorporating the local effects of electronic correlations with dynamical mean-field theory provides reliable estimates of the orbital moment, the mass enhancement and the MAE of YCo5.Comment: 7 pages, 4 figures, published versio
