Chemometrics:  An Important Tool for the Modern Chemist, an Example from Wood-Processing Chemistry

2000

This study briefly outlines the idea of principal component analysis and cross-correlation calculations (applied chemometrics) and presents an illustrative example from wood-processing chemistry. The applicability of chemometric data analysis was demonstrated by investigating the various structural changes that take place in dissolved and degraded lignin ("kraft lignin") during laboratory-scale kraft pulping of Scots pine (Pinus sylvestris) and silver birch (Betula pendula). The structural data (31P NMR and size exclusion chromatographic data) on kraft lignin were further processed by chemometric multivariate techniques (PCA and 2DCC), confirming, for example, that the cleavage of beta-aryl…

An overview of the microbiological characteristics of the wooden shelves used in cheese ripening

2022

Cheese ripening is a complex phenomenon affected by several factors. Among these, the influence of the wooden shelves used for aging traditional cheeses is underrated. The surfaces of the wooden boards are in contact with cheese rind for the entire ripening period and develop a microbial community. The aims of this review article is to provide an overview on the microbiological approaches applied to study the biofilms associated to the wooden tools used for dairy productions and to summarize the studies specifically performed on the wooden shelves used to ripen traditional cheeses. A critical discussion is focused on the hygienic aspects and the safety of these systems applied in cheese pro…

The influence of the wooden equipment employed for cheese manufacture on the characteristics of a traditional stretched cheese during ripening

2015

Abstract The influence of the wooden equipment used for the traditional cheese manufacturing from raw milk was evaluated on the variations of chemico-physical characteristics and microbial populations during the ripening of Caciocavallo Palermitano cheese. Milk from two farms (A, extensive; B, intensive) was processed in traditional and standard conditions. Chemical and physical traits of cheeses were affected by the farming system and the cheese making technology, and changed during ripening. Content in NaCl and N soluble was lower, and paste consistency higher in cheese from the extensive farm and traditional technology, whereas ripening increased the N soluble and the paste yellow and co…

Assessment of bioenergy potential in Sicily: a GIS-based support methodology

2008

Abstract A Geographical Information System (GIS) supported methodology has been developed in order to assess the technical and economic potential of biomass exploitation for energy production in Sicily. The methodology was based on the use of agricultural, economic, climatic, and infrastructural data in a GIS. Data about land use, transportation facilities, urban cartography, regional territorial planning, terrain digital model, lithology, climatic types, and civil and industrial users have been stored in the GIS to define potential areas for gathering the residues coming from the pruning of olive groves, vineyards, and other agricultural crops, and to assess biomass available for energy cu…

Myths of Violence and Female Storytelling in Margaret Atwood’s The Handmaid’s Tale and Kate Atkinson’s Human Croquet

2016

Stories of violence and oppression from classical mythology and fairy tales are redeployed in two novels by Atwood (1985) and Atkinson (1997) as archetypal pre-texts that impact on plot and narrative process. Although they are very different in genre and theme, both novels present first-person female narrators who are trapped in a claustrophobic present, and pose the question of the extent to which a story can be told from within the boundaries traced by myth, fairy tales and quasi-mythical literary texts. Clearly indebted to Orwell’s Nineteen Eighty-Four, The Handmaid’s Tale depicts a dystopian world where women live segregated by a male regime. References to the tale of Little Red Cap, cl…

Ivy and Bones: ruins and reversibility during the Blitz

2012

"Ivy and bones: ruins and reversibility during the Blitz" examines how the representation of the ruins of the Blitz is informed by the aesthetic and semiotic tension between abstraction, modernist purity and picturesque accretion. Subsequently building on the notion of reversibility, it explores the way wartime destruction and/or cultural decline is recorded as well as counteracted and compensated for in works by Elizabeth Bowen, Herbert Furst, Claire Leighton, Rose Macaulay, John Piper, and Virginia Woolf. The trope of reversibility provides a template to consider some of the sites where aesthetic conflicts are re-enacted, from blitzed spaces to the printed page as threatened modernist art…

The Latin Masquerade

2006

El objetivo del presente texto es analizar la figura de lo español y lo latino en el cine norteamericano, apoyándose en la carrera cinematográfica de Antonio Banderas. Las confusiones o superposiciones entre lo latinoamericano y lo español, el papel de lo étnico, la función de la música y el tema del latin lover son visto con nueva luz en los últimos años. The aim of this text is to analyze the role played by the spanishness and the latin in the American film taking as an example the career of Antonio Banderas. Starting by his roles in Almodovar films and finishing up with his passing on the other side of the camera, we consider the overlapping of spanish and latin american in the New Holly…

Problematiche di percorso e di collegamento: “una idea antica, buona per il futuro”

2011

Il legno fa parte della storia dell’uomo, della sua evoluzione sociale e culturale, fin dalle costruzioni su palafitte, che esprimono un’architettura primordiale fondata su due elementi strutturali fondamentali: colonna e architrave, verticale e orizzontale. È questa una idea antica, buona per il futuro, che vede e ricerca l’innovazione a partire dal gesto primordiale che gli antichi praticavano nel gettare un semplice tronco d’albero tra due sponde per oltrepassare un fiume. In questo senso, il legno ritorna ad essere il migliore materiale per la realizzazione di strutture di collegamento, di passerelle pedonali, come quella necessaria a “collegare” la Via Sacra nella Valle dei Templi di …

El plagio cinematográfico de Letty Lynton (1932) y su impacto en la industria fílmica estadounidense: análisis del proceso judicial y de su cobertura…

2016

Este artículo presenta un exhaustivo análisis del proceso judicial relativo al film Letty Lynton (1932), que, pese a ser un emblema del periodo clásico de Hollywood, fue prohibido en 1936, tras la denuncia de dos dramaturgos que acusaron a Metro-Goldwyn-Mayer de haber plagiado una de sus obras. El pleito evidenció una complejidad en materia de infracción del copyright que la justicia estadounidense no había afrontado hasta el momento, entre otros motivos porque la cinta partía de unos hechos reales acontecidos durante el siglo XIX y la productora había adquirido los derechos de una novela que también los relataba. Los continuos recursos y resoluciones judiciales finalizaron, tras ochos años…
