Purpose – A summary of the economic impact resulting from the celebration of a sporting mega-event in the city of Cali Colombia is carried out in this article. Design/methodology/approach – The impacts are estimated by means of the systematic effects produced by the activities of investment/expenditure of the identified agents and the consequent multiplying effects captured from an input-output model. Findings – The World Games represented a new income flow to the city of Cali of $101.036 million pesos (=US$53.4 mill.) and 9.598 jobs were created (=7711 full-time jobs). Additionally 2174 foreign tourists and 11250 national tourists were attracted to the city. Originality/value – The article contributes with innovative aspects methodologically speaking useful for future studies of economic impact in cities with low tourismlocated in developing countries.

The route by chemical solution deposition to grow textured layers of oxide superconductors has received the most scientific attention over the past two decades. Texture plays a predominant role in the technological applications of superconducting layers. We crystallized a precursor solution of Y, Ba and Cu acetates onto single crystal substrates of perovskite structure by the route of chemical solution deposition and we obtained textured superconducting layers of YBa2Cu3O7. We divided our results in two parts: a) We review the epitaxial growth of YBa2Cu3O7 superconducting layers through physical and chemical methods, and b) We study mainly the epitaxial growth of YBa2Cu3O7 superconducting layers by X ray diffraction.

We studied the optimun temperature to favor the epitaxial growth of YBa2Cu3O7 layers using threesintering temperatures of 820, 840 and 860℃, by the chemical solution deposition method in SrTiO3[100] monocrystalline substrates. Surface morphology was obtained by optical imaging, which qualitativelycharacterize the homogeneity and the grain presence along the c-axis. The X-ray diffractionconfirms the preferential epitaxial growth (00l) of the YBa2Cu3O7 crystals, resulting in a higher intensityof the profiles (00l) for the temperature of 860℃. The samples shown superconducting behaviourat critical temperature of 90 K, for the three cases.
