Selecting SUDS in the Valencia Region of Spain

This paper reports on a study of the implementation of sustainable urban drainage systems (SUDS) in two Spanish towns (Xàtiva and Benaguasil) as part of the EU LIFE+ Project AQUAVAL, which has been conceived to introduce examples of sustainable drainage to the Valencia Region of Spain. Six sites in a range of common urban spaces and land uses are selected and appropriate SUDS techniques proposed by means of a decision-support process. This primarily consisted of the systematic application of key selection criteria through matrices and scores, followed by a brief sustainability analysis. Stakeholders’ preferences and opinions as well as educational and social opportunities are highly considered throughout the process. General monitoring requirements and major limitations in using the methodology are outlined, stressing the need for improvement of four main aspects: local data regarding SUDS performance, detail of the sustainability analysis, support through comprehensive modelling tools, and level of stakeholder engagement. The importance of creating showcases for SUDS in Mediterranean Regions, thus adapting key selection criteria as to foster sustainable drainage understanding and expertise is highlighted

Synchronization of the Frenet-Serret linear system with a chaotic nonlinear system by feedback of states

A synchronization procedure of the generalized type in the sense of Rulkov et al [Phys. Rev. E 51, 980 (1995)] is used to impose a nonlinear Malasoma chaotic motion on the Frenet-Serret system of vectors in the differential geometry of space curves. This could have applications to the mesoscopic motion of biological filamentsComment: 12 pages, 7 figures, accepted at Int. J. Theor. Phy

Remarks on vector-valued Gagliardo and Poincar ́e-Sobolev type inequalities with weights

In this paper we review certain extensions of the Gagliardo and Poincar ́e-Sobolev type inequalities to later explore the possibility of extending them to the vector-valued setting. We restrict ourselves to the most classical case of lq-valued functions, where already some difficulties arise, due to the lack of a vector-valued variant of the truncation method, both on the classical and the fractional case. We think that these difficulties may be overcome in the future, and we pose some conjectures in this direction

Formación de la red de investigadores para la mejora de la educación básica en la Secretaría de Educación Jalisco

La formación de la red de investigadores para la mejora de la educación básica responde a una estrategia del Programa Maestro de Investigación Educativa en la Secretaría de Educación del estado de Jalisco (SEI). El propósito es constituir un equipo sólido de investigadores que se forman en la práctica de la investigación, acompañados por investigadores reconocidos, y puedan producir conocimientos pertinentes y prioritarios para los maestros y tomadores de decisiones a través de la cual se haga posible la transformación en el nivel educativo. Se integraron cuatro equipos de investigación: educación indígena, especial, secundaria y física, con proyectos en torno al análisis de la práctica educativa
