Arynic species; effect of substituents on the reactivity of monosubstituted dehydrobenzenes
Abstract Evidence is presented demonstrating the existence of free dehydrobenzenes in the thermal decomposition of diaryliodonium-2-carboxylates, and that o-benzyne itself and its 4-methyl-, 4-chloro-,4-bromo- and 4-nitro-derivatives are generated from insoluble polymer-bound precursors and trapped by a second solid phase in Diels-Alder reactions. Lifetimes for these elusive species are determined.
Arynic species II
Abstract o-Benzyne and its 4-methyl, 4-chloro and 4-bromo-derivatives were generated in the thermal decomposition of two new kinds of polymer-bound precursors: 1(2-carboxyaryl)triazenes and 2-carboxyaryl-sulphonates. New kinds of trapping polymers for these elusive species are also presented.
Run-Time Reconfiguration for Emulating Transient Faults in VLSI Systems
Advances in circuitry integration increase the probability of occurrence of transient faults in VLSI systems. A confident use of these systems requires the study of their behaviour in the presence of such faults. This study can be conducted using model-based fault injection techniques. In that context, field-programmable gate arrays (FPGAs) offer a great promise by enabling those techniques to execute models faster. This paper focuses on how run-time reconfiguration techniques can be used for emulating the occurrence of transient faults in VLSI models. Although the use of FPGAs for that purpose has been restricted so far to the well-known bit-flip fault model, recent studies in fault repres…
Generation of monosubstituted o-benzynes from polymeric reagents via heterolytic fragmentations
Abstract Generation of four 4-substituted o-benzynes by heterolytic — fragmentation reactions is demonstrated.
Valoración del daño corporal por mordeduras: estudio de sentencias de la Audiencia Provincial de Castellón
Las mordeduras se incluyen entre las contusiones complejas. Al igual que ocurre en otras contusiones complejas, por ejemplo en una caída, la tipología lesiva que puede generar una mordedura es variada. De ahí que la valoración medicolegal de dicha contusión dependa del resultado y no del mecanismo de producción. Sin embargo, en ocasiones, en el ámbito penal el mecanismo de origen puede ser tan importante como el resultado lesivo, pues sirve para reconstruir la dinámica del hecho. En este artículo se abordan las principales dificultades periciales en la valoración del daño corporal producido por mordeduras, tanto humanas como de animales y se analizan las sentencias de la Audiencia Provincia…
