A new computer simulator allows to design military strategies based on ants’ movements
A researcher of the University of Granada has designed a new system for the mobility of military troops within a battlefield based on the mechanisms used by ant colonies to move using a commercial videogame.This work, developed at the department of Computer Architecture and Technology of the UGR, has designed several algorithms that permit to look for the best route path (this is, to find the better route to satisfy certain criteria) within a particular (...)

New system of wastewater treatment could reduce the size of treatment plants by half
A group of researchers from the University of Granada (Universidad de Granada) have come up with a wastewater treatment system which has three clear advantages with respect to systems currently used: it is possible to obtain cheaper water of a higher quality, it considerably reduces the size of treatment plants (by more than half) and it minimizes the resulting mud production. José Manuel Poyatos Capilla, researcher from the Department of Civil Engineering of the University (...)

A new system will enable better prediction of the behaviour of old buildings subject to earthquakes
What happens if a big earthquake hits Spain? It is probable that a lot of buildings built before 1974 (the year in which the seismic regulation PDS-74 was passed, obligating all architects to prepare buildings against earthquakes) and even some buildings built after this year, will collapse. That is, they would not survive the earthquake or they would suffer such damage that they would have to be completely demolished. A study by Professor Amadeo Benavent (...)

Researchers from the UGR use a bacterium to obtain biopreservatives from food
The research group “Estudio de sustancias antagonistas producidas por microorganismos” (Antagonistic substances produced by microorganisms), part of the Microbiology Department of the University of Granada (Universidad de Granada), has succeeded in isolating enterocin AS-48, which could have a medium-term use as food biopreservative. This represents a significant advance, given that biopreservation is an innovative method in food-preservation systems based on the use of microorganisms or their metabolic products to inhibit or destroy undesirable microorganisms.Marina Sánchez (...)

A seminar of the UGR analyses concentrically braced frames for use in regions of high seismic risk
The Department of Structure Mechanics of the University of Granada organizes the Seminar Seismic performance of modern concentrically braced frames. The experts will deal with the seismic behaviour of concentrically braced frames for use in regions of high seismic risk in the United States. The Seminar is one of the activities programmes every year by seminar José Antonio García García, a meeting point to spread research news generated in the University of Granada as well (...)

A study of the UGR allows to improve techniques of cold-asphalting
Bitumen is used in traditional asphalting, a sub-product that remains after successive oil refining, and dry goods, stones that confer stiffness on roads. Bitumen acts as adhesive but, as it is a very viscous material, it has to be heated to be used. Since some years ago, big technological innovations have been introduced to carry out the cold process, using the so-called bituminous emulsions, heterogeneous systems composed of two stages or elements, insoluble of each (...)

The University of Granada studies the potential of the “Atlas cedar” as reforestation source in Morocco
Through this study, the Department of Organic Chemistry of the UGR intends to contribute to the revalorization of the forest resources of Morocco. To this extent, the properties of the plant “Atlas cedar” have been studied as a resource for the creation of chemical products applicable to other areas such as medicine or pharmacology. To date, the plant has been exploited as a source of quality wood similar to the legendary “Liban cedar”. Chemical studies (...)

A thesis of the University of Granada unveils the keys of the waterproof capacity of paraffin chipboards
Under the supervision of professors Ignacio Covián Sánchez, Miguel Ángel Cabrerizo Vílchez and Roque Hidalgo Álvarez, this research work of the Department of Applied Physics of the University of Granada has gone deeply into the advantages of using paraffin as a waterproofing element for chipboards. The study has been carried out in the framework of the agreement between the group of fluids and bicolloids physics and the Spanish company Repsol YPF.In addition, it is the (...)

A UGR researcher proposes a formula to measure the seismic resistance of reinforced concrete buildings
Reinforced concrete is one of the most used materials in Spanish constructions. Foreseeing the behaviour of this kind of structures in case of earthquake becomed vital when they are placed in seismic areas such as Granada. Recently, it has been suggested a new formula, confirmed with numerical simulations, which is going to make the prediction of the seismic resistance of reinforced concrete structures easier, based on its capacity to take up and disperse energy.The director (...)

Ins and outs of monumental stones
The University of Granada takes part in a European project that, within the VI Framework Programme, aims to improve maintenance and restoration techniques of cathedrals and historical buildings from an interdisciplinary point of view. Geologists, like those of the research group directed by Eduardo Sebastián Pardo, of the Department of Mineralogy and Petrology of the University of Granada, play an essential role in this network of architects, restorers and physicists.These researchers from Granada have experiences (...)
