Development of a model to predict the durability of reinforced concrete structures in marine environment

Abstract: this paper proposes a model that enable to estimate the durability of reinforced concrete structures exposed to marine environment. to that effect, different models proposed by the literature were used, where the diffusion coefficient is function of the concentration, departing of the fact that the transfer process of the chloride ions is controlled by purely diffusion flow. a total of 44 concrete nucleus served as base for this research. thus, the results of chloride ions contamination determined in different elements of the general rafael urdaneta bridge (pgru) were used. the pgru, a 39 year structure, is located front caribbean sea with a very aggresive environmental condition. the results indicate that it does not exist an unique model that is applied to all the evaluated structure, for the valuation criteria assumed in the selection of the models, but, as a rule depend on the quality of the concrete (equal model for a same element). however, the hall′s model was the one which fit better to the results (70% of the cases).

Chilean University Students’ Call for Participation and Engagement in What Matters to Them: Is It Possible to Achieve a Shared Decision Making Process in Education Policy?  [PDF]
Paulina Bravo, Baltica Cabieses
Creative Education (CE) , 2012, DOI: 10.4236/ce.2012.326155
Abstract: Chile is facing one of its major intellectual revolutions in the last century: organised high school, college and university students have led the most salient educational reform since the one that took place during the dictatorship period. This phenomenon is a pacific revolution based on the power of sound, evidence-based, clear and robust ideas. The purpose of this short essay is to reflect some ideas on the conceptualisation of a shared decision making (SDM) process and how they could be transferred to the current students’ educational revolution in Chile. It provides a reflection on how SDM might concretely contribute to this educational reform and on what future steps could be taken to truly achieves a “participatory” democracy in Chile. According to the authors, this debate illustrates the extent to which the level of participation must rely not on particular individuals but on the establishment of a partnership between parties.
CCS Membrane Development at CIUDEN’s Technology Development Centre for CO2 Capture  [PDF]
Jose A. Gutierrez Bravo
Journal of Power and Energy Engineering (JPEE) , 2018, DOI: 10.4236/jpee.2018.612001
Abstract: CO2 concentration to the atmosphere has risen faster than ever in the last century. This is highly due to fossil fuel combustion which is the major anthropogenic CO2 source. Membrane technology is an important alternative for reliability, flexibility and economically competitiveness for Carbon Capture and Storage (CCS) processes. The use of membranes has applicability to CCS technologies mainly for CO2, O2 or H2 separation, although most of the membrane studies for CO2/O2 production have been carried out at laboratory scale and will require a step further for commercial scale. This paper will present current membranes R & D needs when applied to CCS systems and CIUDEN capabilities for membrane technological development and testing under real conditions. It covers from O2 separation membrane integration in the process, and applied to the oxy-combustion CO2 capture, to post-combustion technologies for membrane CO2 separation, tested under real conditions or H2 production catalytic-membranes through gasification. At CIUDEN CCS facility important membrane evaluations can be carried out for the module integration, testing of materials performance and behavior under real conditions.
