La geometría dinámica con CABRI II

La utilización de una herramienta nueva, de cualquier tipo que sea, necesita de una reflexión sobre lo que hacemos, muchas veces cambia nuestro modo de trabajar (actitud) y hace surgir problemas sobre las verdades que teníamos. En matemática los conocimientos utilizados pueden ser diferentes: comparar una construcción geométrica con regla y compás o con regla y escuadra (mecánica) o solamente con compás. En este curso se explora de manera activa el software Cabri II. En una primera etapa se realiza la construcción de triángulos -sus elementos secundarios- y circunferencias inscritas y circunscritas así como exploraciones de simetría. En una segunda etapa se elaboran macro construcciones o construcciones que podemos grabar, para luego reutilizar en figuras más complejas, sin necesidad de rehacerlas. A través de la exploración ya descrita se reflexiona sobre el aporte de esta herramienta al quehacer pedagógico y/o científico. El uso del software es muy cercano a la forma de pensar en la geometría clásica, lo que permite a los estudiantes acercarse a esta disciplina y hacer conjeturas. Corresponde advertir que, como Cabri II no es un software de dibujo ni de demostración sino que está basado en un ambiente numérico, hay errores de aproximación. aunque leves. Se inicia el curso explicando brevemente el funcionamiento del software Cabri II para pasar a realizar actividades de construcción y comprobación de relaciones geométricas.

Adaptive decision-making in buildingEXODUS in response to exit congestion

Given the importance of occupant behavior on evacuation efficiency, a new behavioral feature has been implemented into building EXODUS. This feature concerns the response of occupants to exit selection and re-direction, given that the occupant is queuing at an external exit. This behavior is not simply pre-determined by the user as part of the initialization process, but involves the occupant taking decisions based on their previous experiences with the enclosure and the information available to them. This information concerns the occupant's prior knowledge of the enclosure and line-of-sight information concerning queues at neighboring exits. This new feature is demonstrated and reviewed through several examples.

The numerical simulation of noncharring thermal degradation and its application to the prediction of compartment fire development

In this paper we present some work concerned with the development and testing of a simple solid fuel combustion model incorporated within a Computational Fluid Dynamics (CFD) framework. The model is intended for use in engineering applications of fire field modeling and represents an extension of this technique to situations involving the combustion of solid fuels. The CFD model is coupled with a simple thermal pyrolysis model for combustible solid noncharring fuels, a six-flux radiation model and an eddy-dissipation model for gaseous combustion. The model is then used to simulate a series of small-scale room fire experiments in which the target solid fuel is polymethylmethacrylate. The numerical predictions produced by this coupled model are found to be in very good agreement with experimental data. Furthermore, numerical predictions of the relationship between the air entrained into the fire compartment and the ventilation factor produce a characteristic linear correlation with constant of proportionality 0.38 kg/sm5/12. The simulation results also suggest that the model is capable of predicting the onset of "flashover" type behavior within the fire compartment.

Excellent correlation between cathepsin B inhibition and cytotoxicity for a series of palladacycles

The reaction of the five- or six-membered C,N or C,S-palladacycles [(L)PdCl](2) with PTA (1,3,5-triaza-7-phosphaadamantane) led to the monomeric complexes [(L)Pd(PTA)Cl] 6a, 6b and 7 where LH= N,N-dimethyl-1-phenylmethanamine, benzyl(methyl)sulfane or 1-methyl-5-phenyl-1H-benzo[e][1,4]diazepin-2(3H)-one respectively. Dimeric complexes have also been synthesised: [Pd(2)L(2)(mu-dppe)Cl(2)], where LH = 1-methyl-5-phenyl-1H-benzo[e][1,4]diazepin-2(3H)-one (1a), (R)- or (S)-3-isopropyl-1-methyl-5-phenyl-1H-benzo[e][1,4]diazepin-2(3H)-one (1b, 1c), [Pd(2)L(2)(mu-dppf)Cl(2)], where L= 1-methyl-5-phenyl-1H-benzo[e][1,4]diazepin-2(3H)-one (4a) or (R)-3-isopropyl-1-methyl-5-phenyl-1H-benzo[e][1,4]diazepin-2(3H)-one (4b), respectively, and dppe = 1,2-bis(diphenylphosphino)ethane, dppf = 1,1'-bis(diphenylphosphino)ferrocene. The complexes were characterised in solution, by (1)H and (31)P NMR spectroscopy, and single crystals of complexes 6b and 7 were studied in the solid state by X-ray crystallography. The palladacycles were evaluated for in vitro activity as cytotoxic agents on A2780/S cells and also as cathepsin B inhibitors, an enzyme implicated in a number of cancer related events.

Synthesis of cycloruthenated compounds as potential anticancer agents

A library of 19 cycloruthenated derivatives is constructed by making use of the well-known cyclometalation reaction. Their geometries are modified in a straightforward manner by addition of either mono- or bidentate ligands, such as bipyridine, phenanthroline, 1,2-bis(diphenylphosphanyl)ethane, dimethylphenylphosphane, triphenylphosphane, and 1,3,5-triaza-7-phosphatricyclo[3.3.1.1]decane (PTA) ligands, to cationic cycloruthenated centers. The antitumor properties of the compounds thus obtained are investigated in order to compare them with recently reported ruthenium complexes and cisplatin. IC50 values against mammalian cells (A-172, HCT-116, and RDM-4) are determined for the library compounds and some of them, such as those derived from orthoruthenated phenylpyridine and a bidentate N,N ligand, display activity of the same order of magnitude as cisplatin.
