The UGR awards the Teaching Innovation Prize to a laboratory that reproduces the geological movements of the Earth

30.01.2007
Reproducing geological situations in the Laboratory of Analogical Modelling of the Department of Geodynamics, a newly created laboratory, unique in Spain, is the objective of this project coordinated by teacher Ana Crespo Blanc, of the department of Geodynamics of the University of Granada (Universidad de Granada [http://www.ugr.es]), which was awarded by the UGR [http://www.ugr.es] with the Teaching Innovation Prize.

The project, titled "Analogical modelling: devising of teaching animations in Geological Sciences" is unique in our country. The experiments involve constructing parallelepipeds of sand, with casual insertions of silicone or glass spheres, on a mobile and interchangeable substratum.

The whole is subjected to compression, extension or sliding with a system of mobile vertical plates with an adjustable movement speed. Deformation thickness and speed are calibrated to simulate suitably the natural phenomenon we want to model.

The modelling device installed in the laboratory allows to photograph at fixed intervals two of the faces of the parallelepiped while it becomes deformed (plant and one of the profiles), which allows to have a vision in 3D of the progressive deformation. Finite deformation geometry can be obtained at the end of the experiment with vertical cuts in the deformed parallelepiped (solidified with water), cuts recorded with a digital camera. In every experiment, an animation is generated from digital stills. From an about two-hour long experiment, a thirty-second film can be obtained.

According to teacher Ana Crespo, "with such animations, students can appreciate qualitatively how the experiments evolves, and observe the progressive deformation in the profile and/or in the plant. They can see how rocks become deformed and form mountain ranges since, by calibrating the experiments, it can be showed in some seconds what happened in million years.

Cazorla mountain range

They can compare the final results with concrete geological cuts they have studied all through the degree course, particularly those regions located to the north of Granada and in the area of Cazorla, which are very similar to those of the laboratory".

An important aspect of this Project is its application to disclosure in the medium term. Particularly, the management of the Parque de las Ciencias (Science Park) of Granada has shown interest in this type of animations to complete the Geology section in the Biosphere hall.

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Im Focus: Three Magnetic States for Each Hole

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
