Chromogenic Detection of Aqueous Formaldehyde Using Functionalized Silica Nanoparticles

2016

Silica nanoparticles functionalized with thiol reactive units and bulky polar polyamines were used for the selective colorimetric detection of formaldehyde. The reaction of thiols groups in the nanoparticles surface with a squaraine dye resulted in loss of the pi-conjugation of the chromophores, and the subsequent bleaching of the solution. However, when formaldehyde was present in the suspension, the thiol-squaraine reaction was inhibited and a chromogenic response was observed. A selective response to formaldehyde was observed only when the thiol and polyamine groups were anchored to the silica surface. The observed selective response was ascribed to the fact that bulky polyamines generat…

La terza via. Nuove regole per trasformare gli spazi aperti nella città pubblica

2014

La tesi secondo la quale i numerosi ed ampli spazi aperti della città pubblica sono tra i luoghi essenziali da cui partire per innescare trasformazioni urbane d’ampio respiro è oggi riconosciuta e ben fondata. Tuttavia al pesante corpus di riflessioni teoriche (ed anche di operazioni reali) effettuate a riguardo, non corrisponde ancora una risposta adeguata in termini procedurali e di definizione delle categorie d’azione possibili e legittime. Tale mancanza pesa sulla possibilità di intervenire in maniera veloce ed adeguata in questi luoghi. Cominciare a riflettere su nuove regole che accolgano e, insieme, normino l’entusiasmo e il successo dimostrato da tante esperienze di trasformazioni i…

Negotiating informal housing in Metro Manila : forging communities through participation

2016

This research project examines socialized housing programs available to informal settlers in the megacity of Metro Manila, Philippines, and the socio-political and institutional relationships that enable or impede access to housing. Megacities are urban agglomerations with populations of over 10 million inhabitants and Asia and Africa contain some of the fastest growing cities in the world. The challenge of Southern governments to meet the housing needs of hundreds of thousands of urban poor is exacerbated by the influx of migrants into these economic hubs, the scarcity of land for low-income housing and the inequalities and infrastructure deficiencies in developing countries’ cities. The s…

The bending triad of the quasi-spherical top molecule SO2F2 in the 550 cm(-1) region

2006

International audience; The analysis of the v(3)/v(7)/v(9) bending triad of SO2F2 has been recently performed with the Watson's Hamiltonian up to octic terms employing 79 rovibrational parameters but including only the first order Coriolis interaction terms, fixed to ab initio values [H. Burger, J. Demaison, F. Hegelund, L. Margules, I. Merke, J. Mol. Struct. 612 (2002) 133-141]. Since SO2F2 is a quasi-spherical top, it can also be considered as derived from the SO42- sulfate ion. We have thus developed a new tensorial formalism in the O(3) > Td > C2v group chain [M. Rotger, V. Boudon, M. Loete, J. Mol. Spectrosc. 216 (2002) 297-307]. This approach allows a systematic development of rovibra…

Actividades de imagen, atenuación e impersonalidad en los juicios orales

2016

Esta tesis trata de determinar la manera en que se configuran las actividades de imagen, la atenuación y la impersonalidad en el discurso de los profesionales del derecho (jueces y abogados) durante el transcurso de los juicios orales. Para la elaboración de este trabajo, partimos de un corpus de ocho juicios orales (dos por cada jurisdicción presente en el ordenamiento jurídico español) que ha sido transcrito siguiendo el sistema de transcripción del grupo Val.Es.Co. (2003). En total, el corpus suma 4 horas, 7 minutos y 9 segundos de grabación y consta de 49227 palabras. El corpus se ha analizado adaptando la ficha metodológica de Albelda et al. (2014) a las necesidades de nuestro género y…

A trie-based approach for compacting automata

2004

International audience; We describe a new technique for reducing the number of nodes and symbols in automata based on tries. The technique stems from some results on anti-dictionaries for data compression and does not need to retain the input string, differently from other methods based on compact automata. The net effect is that of obtaining a lighter automaton than the directed acyclic word graph (DAWG) of Blumer et al., as it uses less nodes, still with arcs labeled by single characters.

Las penúltimas razones de la moralidad en Tugendhat

2017

RESUMEN. El trabajo explora críticamente la idea de una justificación débil o penúltima de la moral enmarcándola en el conjunto de la filosofía de Tugendhat, reordenan do sus escritos éticos y discriminando los diversos aspectos que incluye dicha idea. Entre ellos, revisa el concepto formal de moral, ligado a los sentimientos, antes de centrarse en el punto crucial: la fundamentación de la ética moderna. Aquí se distingue, por un lado, la justificación comparativa de un contractualismo igualitario frente a otras alternativas teóricas y, por otro, los motivos que pueden llevar (more heideggeriano, en realidad) a un individuo autónomo a entenderse en términos morales. ABSTRACT. This paper exp…

Selective derivatisation of resorcarenes: 1. The regioselective formation of tetra-benzoxazine derivatives

1997

Abstract Four 5,6-benzo-1,3-oxazine rings are formed by the condensation of resorcarenes with various aliphatic or aromatic primary amines and formaldehyde. From four possible regioisomers only the C4 symmetrical compound is isolated in yields of up to 90%. Semiempirical calculations confirm its relative stability, which is due to the possible formation of four intramolecular OH…O hydrogen bonds. The regioselectivity of the reaction is further established for two examples by single crystal X-ray analysis. A solvent molecule is included in the extended cavity.

A gloss to the Supreme Court Judgment of 5 March 2019, IV KK 484/17

2019

W glosie przedstawiono problematykę nadzoru prokuratora nad postępowaniem przygotowawczym, prowadzonym przez finansowy organ postępowania przygotowawczego, a także omówiono skutki procesowe objęcia przez prokuratora nadzoru nad takim postępowaniem. Autor wyraża zapatrywanie, iż czynność procesowa prokuratora, wyrażająca się w dalszym przedłużeniu dochodzenia, prowadzonego przez finansowy organ postępowania przygotowawczego, na okres ponad 6 miesięcy, nie jest decyzją o charakterze wpadkowym i nie można jej uznać za czynność techniczną. Czynność ta ma charakter czynności nadzorczej. Konsekwencją przyjęcia, że przedłużenie przez prokuratora, na podstawie art. 153 § 1 zd. 3 k.k.s., na okres po…
