Ethical Hateholders and Negative Engagement. A Challenge for Organisational Communication
2016
Le parole dell'odio. Dal lessico alle pratiche verbali
2017
Argomento dell'articolo è il fenomeno dello "hate speech" (discorso d’odio). La tesi che si sostiene è che tale fenomeno può essere meglio compreso se si parte dal mettere in discussione la netta distinzione tra una tra forma di violenza puramente ‘fisica’ e una puramente ‘verbale’ e si cerca, invece, di mettere a fuoco l’intreccio tra verbalità e violenza nell’essere umano, domandandosi se, ed eventualmente in che modo, il fatto di essere" animali parlanti" modifichi anche il nostro modo di essere violenti. Per fare questo, occorre superare un approccio puramente lessicale o semantico al fenomeno e inserire invece le parole d'odio nelle concrete pratiche verbali nelle quali esse sono utili…
Perheyrittäjyyden arjen kulttuuri : kolmen sukupolven sahatoimintaa
2005
This study focuses on the entrepreneurial longevity of a family business by observing an old sawmill. The activities within the firm are influenced by the change in the Finnish Society during the 20th century and the decline of the village community. The challenge for surviving at the periphery and maintaining operations in a single family over generations is cultural knowledge. Ethnographic approach through thick descriptions provides a chance to follow the change in everyday customs and interpret its meanings, and these are evaluated using critical methodology. The interdisciplinary theoretical foundation and approach combines the disciplines of economy and anthropology. The family busine…
P-C Cross-Coupling Onto Enamides: Versatile Synthesis of α-Enamido Phosphane Derivatives
2012
We report herein the Pd-catalyzed P–C cross-coupling reac- tion between enol phosphates and secondary phosphane–bor- ane complexes or phosphane oxides. The reaction was per- formed under mild conditions, owing to Pd activation of the P–H bonds of the phosphane–boranes (or phosphane oxides) and to the powerful enol phosphate coupling reagents. New useful chiral and achiral α - β -alkenylphosphane derivatives bearing an amido group in the α -position to the P center were obtained in yields up to 70 %.
Guano-related phosphate-rich minerals in European caves
2019
International audience; Guano is a typical deposit found in caves derived from the excretions of bats and in minor cases of birds. These organic deposits decompose and form a series of acid fluids and gases that can interact with the minerals, sediments, and rocks present in the cave. Over sixty phosphates are known and described from caves, but guano decay also often leads to the formation of nitrates and sulfates. In this study twenty-two European caves were investigated for their guano-related secondary minerals. Using various analytical techniques, seventeen phosphates, along with one sulfate (gypsum), were recognized as secondary products of guano decay. Among those minerals, some are …
SrP3N5O: a highly condensed layer phosphate structure solved from a nanocrystal by automated electron diffraction tomography.
2011
The oxonitridophosphate SrP(3)N(5)O has been synthesized by heating a multicomponent reactant mixture that consisted of phosphoryl triamide OP(NH(2))(3), thiophosphoryl triamide SP(NH(2))(3), SrS, and NH(4)Cl enclosed in evacuated and sealed silica-glass ampoules up to 750 °C. The compound was obtained as nanocrystalline powder with needle-shaped crystallites. The crystal structure was solved ab initio on the basis of electron diffraction data by means of automated electron diffraction tomography (ADT) and verified by Rietveld refinement with X-ray powder diffraction data. SrP(3)N(5)O crystallizes in the orthorhombic space group Pnma (no. 62) with unit-cell data of a=18.331(2), b=8.086(1), …
Feasible Low-Phosphorus Dietary Patterns in Maintenance Hemodialysis Patients: Need for Original Research
2020
Introduction The standard low-phosphorus diet restricts pulses, nuts, and whole grains and other high phosphorus foods to control hyperphosphatemia. We conducted a randomized controlled trial to evaluate the effectiveness, safety, and tolerability of the modified diet, which introduced some pulses and nuts, increased the use of whole grains, increased focus on the avoidance of phosphate additives, and introduced the prescription of low-biological-value protein such as bread. Methods We conducted a multicenter, pragmatic, parallel-arm, open-label, randomized controlled trial of modified versus standard diet in 74 adults on hemodialysis with hyperphosphatemia over 1 month. Biochemistry was as…
High accessibility and chemical homogeneity in mesoporous materials: silicas, gold-containing composites and phosphates
2015
El trabajo recopilado en esta tesis está basado en la formación de materiales mesoporosos y sus posibles usos como catalizadores. Este trabajo se ha estructurado en cuatro partes diferenciadas. En primer lugar se presenta una breve introducción a los materiales mesoporosos revisando su evolución en la historia, los diferentes métodos de síntesis, su versatilidad en cuanto a funcionalización y aplicaciones y acabando con un repaso al trabajo realizado en el grupo de investigación. El segundo capítulo está centrado en el mejor conocimiento de la sílice UVM-7, un material mesoporoso de carácter bimodal desarrollado por el grupo. En primer lugar se estudia en detalle la estructura del material …
Removal of silicon from CFB-derived fly ash leachate in the context of phosphorus recovery
2018
High concentrations of dissolved silica in the acid leachate impose two major challenges on precipitation based recovery of phosphorus (P). Firstly, co-precipitation of colloidal silica in the acidic regimes decreases the purity and value of precipitated P-products. In addition, silica scaling on internal surfaces of equipment is also a problematic issue in industrial operations. Therefore, removal of dissolved silica prior to P-recovery process minimizes the risks of Si-contamination in P-products and Si-scaling. In the present study, silica removal was achieved by accelerated silica polymerization with higher acidity and ionic strength of mineral acid, which also assisted the leaching of …
Facile and efficient chemical functionalization of aliphatic polyesters by cross metathesis
2016
International audience; An effective preparation of new tailor-made macromolecular materials via a combination of two (atom-efficient) catalytic transformations is reported. First, new aliphatic polyesters with alternated composition have been prepared using a salen aluminum catalyst system. Next, the pendant vinyl moieties in those copolymers have been selectively transformed into various functional groups by metathesis in the presence of homogeneous Grubbs catalysts. The latter metathesis reaction has been optimized in terms of catalytic activity and selectivity, to define the conditions for an effective and safe procedure that does not affect the macromolecular architecture. All polymer …
