The discursive legitimation strategies of a nascent market

2017

Since the introduction of Gold&Green Foods Ltd’s Pulled Oats (Nyhtökaura) to the Finnish market in the spring 2016, the Finnish media has been increasingly reviewing different plant-based protein products. Gold&Green Ltd’s Pulled Oats has experienced extensive media coverage amongst other Finnish plant-based protein products which have been launched during 2016 such as VersoFood Ltd’s Härkis, Viipurilainen Kotileipomo’s Puhtikaura etc. It has yet to be seen whether the sudden inception of several plant-based protein product innovations will be defined as a pivotal era in the Finnish food industry or just a passing trend. Finnish media has aldo categorized MiFu as one of the up and coming fo…

“Versus aurei” nella poesia di Walahfrido Strabone

2018

Walahfrido Strabone può essere senz’altro considerato il più importante poeta dell’età carolingia. Vissuto fra l’809 e l’849, egli ha composto alcuni poemetti di vario genere e di diversa tipologia (Visio Wettini, Hortulus, Vita Mammae, Versus de beati Blaithmaic vita et fine, Versus de imagine Tetrici), nonché una gran quantità di carmina che rivelano la sua grande perizia metrica e versificatoria. In questa postilla, dopo una prima parte dedicata allo status degli studi sullo scrittore carolingio, sulla sua vita e sulla sua produzione poetica, si dà particolare risalto a un artificio versificatorio da lui praticato, ossia il ricorso al "versus aureus", la cui frequenza e la cui incidenza …

Ostensori architettonici in Sicilia tra suggestioni iberiche e rinascimentali

2022

Through the analysis of six architectural monstrances housed in churches and museums in Sicily, the formal and compositional languages that, between Iberian and Renaissance suggestions, characterize these masterpieces of sacred art are analyzed. They are small silver architectures, produced between the fifteenth and seventeenth centuries, which are influenced by the Catalan Gothic influences and the Italian Renaissance, in a peculiar Sicilian synthesis.

Cyanido-Bridged FeII-MI Dimetallic Hofmann-Like Spin-Crossover Coordination Polymers Based on 2,6-Naphthyridine

2017

[EN] Two new 3D spin-crossover (SCO) Hofmann-type coordination polymers {Fe(2,6-naphthy)[Ag(CN)2][Ag2(CN)3]} (1; 2,6-naphthy = 2,6-naphthyridine) and {Fe(2,6-naphthy)- [Au(CN)2]2}·0.5PhNO2 (2) were synthesized and characterized. Both derivatives are made up of infinite stacks of {Fe[Ag(CN)2]2- [Ag2(CN)3]}n and {Fe[Au(CN)2]2}n layered grids connected by pillars of 2,6-naphthy ligands coordinated to the axial positions of the FeII centers of alternate layers.

Comparison of machine learning models for gully erosion susceptibility mapping

2020

© 2019 China University of Geosciences (Beijing) and Peking University Gully erosion is a disruptive phenomenon which extensively affects the Iranian territory, especially in the Northern provinces. A number of studies have been recently undertaken to study this process and to predict it over space and ultimately, in a broader national effort, to limit its negative effects on local communities. We focused on the Bastam watershed where 9.3% of its surface is currently affected by gullying. Machine learning algorithms are currently under the magnifying glass across the geomorphological community for their high predictive ability. However, unlike the bivariate statistical models, their structu…

Regeneration of the cell wall in protoplasts of Candida albicans. A cytochemical study using wheat germ agglutinin and concanavalin A.

1988

To assess the dynamics of synthesis of the wall by regenerating Candida albicans protoplasts deposition of chitin and mannoproteins were investigated ultrastructurally using wheat germ agglutinin conjugated with either horseradish peroxidase or colloidal gold, and Concanavalin A coupled to ferritin respectively. Freshly prepared protoplasts lacked wheat germ agglutinin receptor sites but after 1-2 h of regeneration, they were detected. After 4-5 h of regeneration, the cell wall showed a discrete structure which was only labelled with wheat germ agglutinin in thin sections. At this stage of regeneration the outermost layer of the wall was labelled with clusters of Concanavalin A-ferritin par…

SNOM signal near plasmonic nanostructures: an analogy with fluorescence decays channels

2008

International audience; Scanning Near-field Optical Microscope (SNOM) is based on local excitations of nanostructures deposited on a substrate (illumination mode). Ideally, the local source behaves like a dipolar emitter so that the SNOM signal is strongly similar to the fluorescence decay rates of an excited molecule that would be located at the SNOM tip position. We present here how the SNOM signal near plasmonic nanostructures can be used to analyze radiative and non-radiative contribution to the fluorescence decay rate.
