Large molecular motions are tolerated in crystals of diamine double salt of trans-chlorocinnamic acids with trans-1,2-diaminocyclohexane

Contrary to the general assumption that photoreactions in crystals may not proceed with large molecular motions, a pedal-like motion prompted by electronic excitation is believed to be involved during the β-dimer formation from the crystals of the diamine double salt of trans-2,4-dichlorocinnamic acid and trans-1,2-diaminocyclohexane.

Revisiting the Mechanism of the Triosephosphate Isomerase Reaction: The Role of the Fully Conserved Glutamic Acid 97 Residue

An analysis of 503 available triosephosphate isomerase sequences revealed nine fully conserved residues. Of these, four residues-K12, H95, E97 and E165-are capable of proton transfer and are all arrayed around the dihydroxyacetone phosphate substrate in the three-dimensional structure. Specific roles have been assigned to the residues K12, H95 and E165, but the nature of the involvement of E97 has not been established. Kinetic and structural characterization is reported for the E97Q and E97D mutants of Plasmodium falciparum triosephosphate isomerase (Pf TIM). A 4000-fold reduction in k(cat) is observed for E97Q, whereas the E97D mutant shows a 100-fold reduction. The control mutant, E165A, which lacks the key catalytic base, shows an approximately 9000-fold drop in activity. The integrity of the overall fold and stability of the dimeric structure have been demonstrated by biophysical studies. Crystal structures of E97Q and E97D mutants have been determined at 2.0 angstrom resolution. In the case of the isosteric replacement of glutamic acid by glutamine in the E97Q mutant a large conformational change for the critical K12 side chain is observed, corresponding to a trans-to-gauche transition about the C gamma-C delta (chi(3)) bond. In the E97D mutant, the K12 side chain maintains the wild-type orientation, but the hydrogen bond between K12 and D97 is lost. The results are interpreted as a direct role for E97 in the catalytic proton transfer cycle. The proposed mechanism eliminates the need to invoke the formation of the energetically unfavourable imidazolate anion at H95, a key feature of the classical mechanism.

The cold mode: a phenomenological model for the evolution of density perturbations in the intracluster medium

Cool cluster cores are in global thermal equilibrium but are locally thermally unstable. We study a non-linear phenomenological model for the evolution of density perturbations in the intracluster medium (ICM) due to local thermal instability and gravity. We have analysed and extended a model for the evolution of an overdense blob in the ICM. We find two regimes in which the overdense blobs can cool to thermally stable low temperatures. One for large t(cool)/t(ff) (t(cool) is the cooling time and t(ff) is the free-fall time), where a large initial overdensity is required for thermal runaway to occur; this is the regime which was previously analysed in detail. We discover a second regime for t(cool)/t(ff) less than or similar to 1 (in agreement with Cartesian simulations of local thermal instability in an external gravitational field), where runaway cooling happens for arbitrarily small amplitudes. Numerical simulations have shown that cold gas condenses out more easily in a spherical geometry. We extend the analysis to include geometrical compression in weakly stratified atmospheres such as the ICM. With a single parameter, analogous to the mixing length, we are able to reproduce the results from numerical simulations; namely, small density perturbations lead to the condensation of extended cold filaments only if t(cool)/t(ff) less than or similar to 10.

等离子体射流产生与特性的实验研究

本文报道热等离子体射流产生及射流特性的实验研究结果.采用同一个直流等离子体发生器,工作气体流量小时产生出层流等离子体长射流,射流长度随气体流量或弧电流的增加而明显增加;工作气体流量大时则产生出湍流等离子体短射流,此时射流长度几乎与工作气体流量或弧电流无关;在层流与湍流等离子体射流工况之间,存在一个流动状况不稳定的过渡区,此时等离子体射流的平均长度随气流量的加大而减小,但随弧电流的加大而明显加大.层流等离子体长射流有相当好的刚性.

Evaluacion de cuatro variedades de frijol comun (Phaseolus vulgaris L.) bajo dos sistemas de labranza sobre el manejo de malezas, crecimiento y rendimiento del cafe (Coffea arabica L.) en laepoca de postrera 1996

En el Centro de Capacitación y Servicio Regional del Pacifico (C.C.S.R.P.), Jardín Botánico, municipio de Masatepe, departamento de Masaya, se realizó el presente trabajo en los meses de julio a diciembre de 1996, con el objetivo de evaluar el efecto de cuatro variedades de frijol común (Phoseolus vulgaris L.), dos criollas (Rojo Nacional y Renegrido) y dos mejoradas (Estelí-150 y Bronca), bajo dos sistemas de labranza (minima y cero) como cultivo intercalado sobre el manejo de las malezas, crecimiento y rendimiento del café ( Coffoa arabica L.). Este ensayo se realizó en un café injertado (Robusta-Catrenic), de 2 afios de edad, se estableció bajo Bloques Completos al AzN (BCA) con cuatro repeticiones. La menor abundancia y dominancia de malezas se encontró en el tratamiento donde sembró el frijol con labranza cero, sin embargo las diferentes variedades utilizadas presentaron comportamientos variables. Las malezas mas dominantes y frecuentes fueron: Me/antera aspera (Jacquin) L. C., Priva lappulacca (L) Pers, Leptochloafiliforme (Lam) Beauv y Melampodium diviricatum (L. Rich. expers). En cuanto al crecimiento del café, la longitud de la tercera y quinta bandola presentó diferencias significativas, para la tercera bandola la mayor longitud se encontró en el tratamiento Renegrido-mínima con 36.25 cm y para la quinta bandola el tratamiento Rojo Nacional-Cero con 54.50 cm. El rendimiento del café no presentó diferencias significativas, el mayor rendimiento se mostró en el tratamiento Bronco-mínima con 191.25 kg/ha de café oro, lo cual indica que el asocio del cultivo del frijol común no influye en el primer año de producción del café.

Carbon nanotube alignment via electrohydrodynamic patterning of nanocomposites

Electrohydrodynamic (EHD) pattern formation in carbon nanotube-polymer composite films yields well-defined patterns on the micrometer scale along with the alignment of carbon nanotubes (CNTs) within these patterns. Conductive pathways in nanotube networks formed during EHD patterning of nanocomposite films results in a substantial increase in the composites' conductivity at loadings exceeding the percolation threshold. The degree of nanotube alignment can be tuned by adjusting the EHD parameters and the degree of alignment is mirrored by the conductivity across the film. Using etching techniques or by embedding relatively long nanotubes, patterned surfaces decorated by CNT brushes were generated. Copyright © 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

Desde las fragmentaciones sociales hasta las vulnerabilidades individuales : perspectivas para la psicología del mañana

Resumen: Esta conferencia propone una puesta en perspectiva sociohistórica del simposio “Riesgos, desigualdades y fragmentaciones sociales vinculados al trabajo”. Eso recuerda primero que los fenómenos de fragmentación social y de vulnerabilidad adulta estuvieron, desde 1895, en el origen y la gestación de las principales corrientes de la psicología. Posteriormente se cambia a la lógica “fragmentación-vulnerabilidad” a través de los conceptos de precariedad y de vulnerabilidad psicológica. Finalmente se sugiere que, distinguiendo la fragilidad humana de la vulnerabilidad adulta, la psicología puede por un lado entender mejor la actual obsesión de prevención de los riesgos y por otra parte la oscilación adulta entre fragmentación “vulnerabilizante” y conciliación fatigante
