Genericity of dimension drop on self-affine sets

2017

We prove that generically, for a self-affine set in $\mathbb{R}^d$, removing one of the affine maps which defines the set results in a strict reduction of the Hausdorff dimension. This gives a partial positive answer to a folklore open question.

Synthesis, structure, and nuclease properties of several binary and ternary complexes of copper(II) with norfloxacin and 1,10 phenantroline

2007

Three new binary Cu(II) complexes of norfloxacin have been synthesized and characterized. We also report the synthesis, characterization and X-ray crystallographic structures of a new binary compound, [Cu(HNor)(2)]Cl(2).2H(2)O (2) and two new ternary complexes norfloxacin-copper(II)-phen, [Cu(Nor)(phen)(H(2)O)](NO(3)).3H(2)O (4), and [Cu(HNor)(phen)(NO(3))](NO(3)).3H(2)O (5). The structure of 2 consists of two crystallographically independent cationic monomeric units of [Cu(HNor)(2)](2+), chloride anions, and uncoordinated water molecules. The Cu(II) ion is placed at a center of symmetry and is coordinated to two norfloxacin ligands which are related through the inversion center. The struct…

Synthesis of tritiated derivatives of the diphenylether herbicides acifluorfen and acifluorfen methyl

1992

Acifluorfen 1 and acifluorfen methyl 2, two herbicides of the diphenylether family, are inhibitors of protoporphyrinogen oxidases. Two tritiated derivatives of these compounds, namely 3-[3H]-5-[2-chloro-4-(trifluoromethyl)phenoxy]-2-nitrobenzoic acid [3H]-1, and methyl 3-[3H]-5-[2-chloro-4-(trifluoromethyl)phenoxy]-2-nitrobenzoic acid [3H]-2, have been synthesised from 3-[3H]-5-hydroxybenzoic acid, in order to probe their interactions with the target enzymes.

'A Shared Reality between a Journalist and the Audience': How Live Journalism Reimagines News Stories

2021

Live journalism is a new journalistic genre in which journalists present news stories to a live audience. This article investigates the journalistic manuscripts of live journalism performances. With the focus on texts, the article reaches beyond the live performance to explore the wider implications and potentials pioneered by live journalists. The data were gathered from <em>Musta laatikko</em> (‘Black Box’) manuscripts, a live journalism production by the Finnish newspaper <em>Helsingin Sanomat</em>. The manuscripts were analysed as <em>eudaimonic journalism</em> through four conceptual dimensions: self-transcendence, autonomy, competence, and relatedne…

Interpretación paleohidrológica y geoarqueológica del substrato romano y musulmán de la ciudad de Valencia

1990

SE ESTUDIA EL REGISTRO GEOARQUEOLOGICO, ROMANO Y MUSULMAN DE LA CIUDAD DE VALENCIA. SE OBSERVAN CUATRO NIVELES DE SEDIMENTACION DIFERENCIADOS: UN SUELO HIDROMORFO DE EPOCA PRERROMANA, LIMOS Y ARENAS DE DESBORDAMIENTO EN FACIES OVERBANK Y CREVASSE SPLAY DEL PERIODO ROMANO, ARCILLAS Y LIMOS ORGANICOS TARDO ROMANOS Y, FINALMENTE, SECUENCIAS VERTICALES DE SEDIMENTOS DE GRANO MUY GRUESO EN FACIES DE BARRAS Y DEPOSITOS DE CANAL DE EPOCA MUSULMANA. LOS DEPOSITOS DE INUNDACION DE EPOCA HISTORICA CORRESPONDEN A FASES DE PROGRADACION CONTINENTAL EN LA LLANURA COSTERA. (A)

Sulfuric acid water table caves (Grotte du Chat / Acqua Fitusa /Bad Deutsch Altenburg + Kraushöhle).

2014

Sulfuric acid caves can display a variety of forms, from 3D maze systems, to isolated chambers, and more or less maze-like water table caves. Most of the voids are normally generated at or immediately above the water table, where condensation-corrosion processes are dominant, creating a set of characteristic meso- and micromorphologies. This paper deals with the description of four very typical sulfuric acid water table caves: the Grotte du Chat in Provence (France), the Acqua Fitusa Cave in Sicily (Italy), and the Bad Deutsch Altenburg and Kraushöhle caves in Austria.

Morphology and evolution of sulphuric acid caves in South Italy

2016

Sulphuric acid speleogenesis (SAS) related to the upwelling of acid water enriched in H2S and CO2 represents an unusual way of cave development. Since meteoric infiltration waters are not necessarily involved in speleogenesis, caves can form without the typical associated karst expressions (i.e. dolines) at the surface. The main mechanism of sulphuric acid dissolution is the oxidation of H2S (Jones et al., 2015) which can be amplified by bacterial mediation (Engel et al., 2004). In these conditions, carbonate dissolution associated with gypsum replacement, is generally believed to be faster than the normal epigenic one (De Waele et al., 2016). In Italy several SAS caves have been identified…

Suoli particolari

2017

Il capitolo analizza le problematiche di natura chimica relative ai suoli che, a causa di particolari fenomeni ambientali e di specifiche pratiche agronomiche, finiscono con l’acquisire alcune proprietà particolari che si discostano da quelle della maggior parte dei suoli di comune uso agrario. Nella fattispecie, sono stati presi in considerazione: a) i suoli acidi, con l’analisi delle cause di acidificazione e delle metodiche per la correzione di tale limite; b) le varie tipologie di suoli sommersi, con le varie controindicazioni che la sommersione comporta; c) i suoli alomorfi, cioè affetti da vari tipi di salinità (suoli salini, salino-sodici e sodici), con particolare riferimento alla l…
