Vitis vinifera - a chemotaxonomic approach: Anthocyanins in the skin

The gaining of new knowledge about varietal differences in grapevines can be useful for the designing of genetic improvement programs. More and more, chemical methods complement ampelographic ones in the study of variability in grapevines. This work is aimed at the anthocyanin profiling of red-coloured grapes, of which ca. 120 cultivars were sampled; among these there were a high number of old Italian vines and 30 Vitis vinifera ssp. silvestris originating from different areas of Italy. Anthocyanins were HPLC separated and quantified with the aid of an inverse phase microbore column and a photodiode detector. Grapevines were numerically separated in groups using as indexes the percentage of the 5 monoglucosides present, the summations of: acetic esters; malvidin-3-monoglucoside-caffeoate plus all 5 p-coumaric esters; as well as a series of relations correlated to certain enzymatic activities necessary for the esterification of glucosides, hydroxylation and methylation in the biosynthesis of several anthocyanins. Data derived from the study of indexes of varietal enzymatic activity enable us to qualify differences between grapevines linked to the synthesis of anthocyanins. The stability of anthocyanic profiles within the same grape variety enables the use of this technique for taxonomic purposes. This research study discusses the use of this technique for classification and analysis of grape phylogenesis. An in-depth look into the relations between cultivated and wild varieties is given

Vitis vinifera - a chemotaxonomic approach: Seed storage proteins

The IEF pattern of the constituent peptides for the storage protein from Viris vinifera endosperm is used for the construction of a dendrogram relating 74 seed specimens

Partnership Encounters in Literature(s), Poetry and Voices from Other Worlds

The academic bulk of this year’s Blue Gum contains texts in both English and Italian. Out of fourteen articles, seven are in Italian and seven in English. They all scrutinise and illuminate a diversity of relevant literary works under the lens of the biocultural partnership-domination theory (Eisler 1987). The literary texts in this issue range from the ancient to the contemporary, from ‘canon’ to post-decolonial literature, in a joyful variety of interrelated recurrences, connections and encounters. William Shakespeare, Walter Scott, Doris Lessing, Ursula Le Guin, Bram Stoker, David Malouf and Jean Rhys are just few of the many writers tackled by our invited authors

Modeling the StaticBehaviour of a Double Curvature Brickwork Vault\u94

For safety assessment, a double curvature hollow bricks cloister vault with lunettes has been studied. Its geometry, constructive aspects, crack pattern have been surveyed and a 3D finite element analysis has been carried out, the numerical model exploiting the accurate survey of the vault geometry

Censimento delle architetture Liberty nel territorio di Varese, Area nord, sentiero 10

L’ indagine condotta sul territorio della Provincia di Varese al fine di individuare e censire gli edifici e i manufatti architettonici Liberty ha avuto come oggetto il territorio attraversato dal Sentiero 10, file rouge dell’intero progetto “Viaggiando Liberty”. La scelta di lavorare su un’area limitata ha consentito di sperimentare un metodo di lavoro che permettesse di raccogliere le informazioni necessarie verificandone l’efficacia prima di estenderlo, con gli affinamenti necessari, all’intero ambito provinciale. Fondamentali, per delineare un quadro quanto più completo possibile della realtà indagata, sono risultati essere sia la conoscenza diretta del territorio sia lo studio di ogni forma di documentazione reperibile

Damage Evaluation of Historic Towers: Procedure for Their Integrity Assessment

The case studies of some damaged historic towers in Italy are presented. The civic tower of Biella, the bell tower of Arcisate and the tower of Castelleone are characterized by the presence of crack patterns indicating different structural damage. A methodology is put forward for combining laboratory and non-destructive testing methods with monitoring systems in order to reach the goal of evaluating the state of conservation of historic towers and its evolution in time, in view of effective intervention design

CRACKING OF THE APSE OF S. LORENZO IN CREMONA: STRUCTURAL INVESTIGATION AND MONITORING

The Basilica of St. Lorenzo in Cremona (Italy) dating back to XII century was investigated for the coming restoration. After a complex investigation, articulated at different levels and aimed to understand the historical evolution of the Basilica of S. Lorenzo at Cremona (Italy), its constructive techniques and the crack pattern in its spatial development, a strengthening intervention has started in the main nave. The results of the investigation carried out on the apse will allow to calibrate suitable analytical models in order to complete the structural diagnosis and to choose appropriate techniques for the preservation of the whole monument
