The aim of this paper is to explore the major issues involved in introducing sustainability concepts into university curricula in an interdisciplinary manner, through Systems Thinking. It is generally accepted that a holistic approach is essential in sustainability studies, but teaching such a new and complex topic to a diverse student population is by no means easy. In this study, sustainability is viewed in the context of Systems Thinking, particularly in Complexity Management domain. A general framework is proposed with the intension of guiding potential instructors who are planning to teach sustainability through Systems Thinking. The framework includes only the suggested systems-oriented material and a review of some system methodologies; it does not cover sustainability issues. Methodologies known as System Dynamics and Soft Cybernetics are explored and emphasized particularly in the paper due to their importance. The framework is kept general enough so that it appeals to students and instructors with a variety of background.

AIM:To evaluate pre-lung transplant acid reflux on p H-testing vs corresponding bolus reflux on multichannel intraluminal impedance(MII) to predict early allograft ***:This was a retrospective cohort study of lung transplant recipients who underwent pretransplant combined MII-p H-testing at a tertiary care center from January 2007 to November 2012. Patients with pre-transplant fundoplication were excluded. Time-to-event analysis was performed using a Cox proportional hazards model to assess associations between measures of reflux on MII-p H testing and early allograft injury. Area under the receiver operating characteristic(ROC) curve(c-statistic) of the Cox model was calculated to assess the predictive value of each reflux parameter for early allograft injury. Six p H-testing parameters and their corresponding MIImeasures were specified a priori. The p H parameters were upright,recumbent,and overall acid reflux exposure; elevated acid reflux exposure; total acid reflux episodes; and acid clearance time. The corresponding MII measures were upright,recumbent,and overall bolus reflux exposure; elevated bolus reflux exposure; total bolus reflux episodes; and bolus clearance ***:Thirty-two subjects(47% men,mean age:55 years old) met the inclusion criteria of the study. Idiopathic pulmonary fibrosis(46.9%) repres e n t e d t h e m o s t c o m m o n p u l m o n a r y d i a g n o s i s leading to transplantation. Baseline demographics,pre-transplant cardiopulmonary function,number of lungs transplanted(unilateral vs bilateral),and posttransplant proton pump inhibitor use were similar between reflux severity groups. The area under the ROC curve,or c-statistic,of each acid reflux parameter on pre-transplant p H-testing was lower than its bolus reflux counterpart on MII in the prediction of early allograft injury. In addition,the development of early allograft injury was significantly associated with three pre-transplant MII measures of bolus reflux:overal

Merging all available databases, a comprehensive and updated earthquake catalogue for El Salvador and surrounding areas has been compiled, containing a total of 2,584 events for the period 1528-2009, covering the geographic window delimited by the coordinates 11.0°-16.5° N and 85.5°-92.0° w, focal depths of 0.0 to 304 km, and the moment magnitudes in the interval 5.0 〈 Mw 〈 8.1. Events in the catalogue are distributed into six seismogenic sources taking into consideration the tectonic regime affecting E1 Salvador, the interplay and complexities between shallow crustal, intraplate and interface subduction seismicity has been thoroughly investigated, primarily with the aim of developing detail criteria to delimit the seismogenic sources in order to perform a consistent seismic hazard assessment. A uniform hazard spectrum for San Salvador and seismic hazard maps and their uncertainty have been calculated for the horizontal component of ground motion for rock site conditions using zone and zone free methods. The references cited in the article constitute a comprehensive list of sources of information on the tectonics and seismicity of El Salvador and neighboring Central American countries.

The ability of some nanostructured materials to perform as effective heterogeneous catalysts is potentially hindered by the failure of the liquid reactant to effectively wet the solid catalyst surface. In this work, two different chemical reactions, each involving a change of phase from liquid to gas on a solid catalyst surface, are investigated. The first reaction is the catalyzed decomposition of a H2O2 monopropellant within a micro-chemical reactor chamber, decorated with RuO2 nanorods (NRs). The second reaction involves the electrolysis of dilute aqueous solutions of H2SO4 performed with the cathode electrode coated with different densities and sizes of RuO2 NRs. In the catalyzed H2O2 decomposition, the reaction rate is observed to decrease with increasing catalyst surface density because of a failure of the liquid to wet on the catalyst surface. In the electrolysis experiment, however, the reaction rate increased in proportion to the surface density of RuO2 NRs. In this case, the electrical bias applied to drive the electrolysis reaction also causes an electrostatic force of attraction between the fluid and the NR coated surface, and thus assures effective wetting.
