Manipulación de cargas con puentes-grúa y polipastos. IEXD0108

As part of the preparation for the fib Model Code for Concrete Structures 2010, task group 4.5 Bond Models undertook a major review of rules for bond and anchorage of reinforcement in the CEB-FIP Model Code 1990. This bulletin presents the outcome of that review, describes the rationale for the revisions and presents the evidence on which the revisions are based. The principle changes in MC2010 include raising the limit on concrete strength that may be used when determining bond resistance to 110MPa, introduction of a coefficient η4 to cater for different reinforcement Classes, and coverage...

Crónica descarnada sobre la cuenca del río Matanza-Riachuelo a través de las voces de todos sus protagonistas: industriales inescrupulosos, habitantes de las villas, agentes del Estado (Justicia, Policía, Acumar), ONGs. La contaminación del medio ambiente como cuestión histórica, política, económica, social y cultural.

There is an increasing challenge for chemical industry and research institutions to find cost-efficient and environmentally sound methods of converting natural resources into fuels chemicals and energy. Catalysts are essential to these processes and the Catalysis Specialist Periodical Report series serves to highlight major developments in this area. This series provides systematic and detailed reviews of topics of interest to scientists and engineers in the catalysis field. The coverage includes all major areas of heterogeneous and homogeneous catalysis and also specific applications of...
