This paper presents a study of the upwelling of tropical cyclones Iván (2004) and Gustav (2008), both associated with coastal flooding in the area. The Delft3D-FLOW model was applied in order to determine its influence on the total sea surges that occurred. Graphs of sea elevation due to upwelling were obtained at La Coloma, Playa Bailen, Cabo de San Antonio, Playa Bibijagua and Carapachibey. In the absence of measured data, it was validated by comparing the results with previous studies and modeling in another area, with the presence of sea level measurement stations, but applying the same methodology. Finally, it was concluded that the application of the model under the methodology used correctly described the phenomenon. [ABSTRACT FROM AUTHOR]

The simulation of a phenomenon in a free circulation regime requires study and practice time. In the present work, recommendations are provided for the creation of models in the ANSYS Fluent software in a fast and precise way, from the evaluation of different configurations, taking as a work to model the single-cycle labyrinth weirs. The objective is to facilitate the habitual use in personal computers of this tool for its application in engineering projects. [ABSTRACT FROM AUTHOR]

This paper presents a brief look at the evolution of university libraries and a change to a new library model named "Learning and Research Resource Center - CRAI (in Spanish, Centro de Recursos para el Aprendizaje y la Investigación"). Here, the paper shows the results obtained on a diagnosis conducted in Universidad de la Havana's library network ( in Spanish, Red de Bibliotecas de la Universidad de La Habana); we propose a series of strategic lines to work and actions to transform this network into a CRAI, and finally, the paper proposes a CRAI model for Universidad de La Habana.

The strip of Pand north of heavy crude oil represents the main source of Cuban hydrocarbons. About the reservoirs several thickness of clayey sediments are reported. Such sequences of these rocks characterize the base of Vega Alta formation providing a sealing character. Recently scanning electron microscopy with X ray microanalysis have been used as part of a methodology of analysis, developed for clayey seal rock characterization in thouse strip of land. This methodology consisted on the integration of the morphological and chemical information. These techniques were applied to drilling cores and outcrop samples. The results of the analysis allowed to get information about the nature of the seal rocks, which is important aspect to take into account for the hydrocarbon exploration. With the application of these techniques, clays belonging to the complex mixture illite, smectite were determined. The spectra obtained by x-ray fluorescence, corresponding to clayey rocks. The chemical composition evidence the nature of these rocks, where the major elements are silicon, aluminum, calcium and magnesium. These studies allowed a better characterization of the oil seal, and allowed more detailed studies, not only in the strip of land north and also in other areas, aspect which is the main objective of the present research.

In Cuba, due to the need to measure the flows that circulate through small and large diameter conductors and given the momentary impossibility of acquiring high-tech solutions in international markets, these solutions have begun to be implemented as a provisional alternative variant to carry out these measurements. This paper is a summary of the main aspects that must be kept in mind when undertaking the design and construction of a proportional flowmeter, emphasizing the potentialities and weaknesses of each of the solutions that can be implemented for such purposes.
