La tomba 24 della necropoli della Ca’ Morta e l’inizio del periodo Golasecca II a Como
No full textL’articolo ha per oggetto lo studio della tomba 24 della necropoli della Ca’ Morta (Como), scoperta nel dicembre 1958. Si rileva, dalla collazione di diverse fonti (diario di scavo, comunicazione alla Soprintendenza Archeologica, pubblicazione preliminare nella RAC del 1958 e pubblicazione del 1966 da parte di F. Rittatore), che alcuni materiali sono attualmente dispersi. Segue il catalogo di tutti i materiali attualmente conservati al museo archeologico P. Giovio di Como. Dopo una breve ricognizione della storia delle ricerche sull’articolazione cronologica della cultura di Golasecca, si procede allo studio tipologico e cronologico degli oggetti di corredo. L’analisi delle ossa combuste ha permesso di attribuire la tomba a un soggetto adulto di genere femminile e ciò è confermato dagli oggetti del corredo: le fibule a navicella e ad arco composto con ambra, i pendagli a melagrana, i dischi ferma-pieghe e gli orecchini in lamina bronzea, sono tutti elementi caratteristici del costume femminile. Dal punto di vista cronologico ci sono da una parte elementi di continuità con la fase Golasecca I C, dall’altra – e più numerosi- gli elementi di novità che consentono di attribuire la tomba agli inizi del Golasecca II (fase G. II A).The paper deals with the study of tomb 24 from the Ca’ Morta cemetery (Como). The tomb was discovered in late December 1958 near the Gini quarry, in the southernmost part of the Ca’ Morta cemetery. The collation of the sources – excavation diary, letters to the Archaeological Superintendence, preliminary publication (RAC 1958) and publication by F. Rittatore (1966) – made it possible to detect that some materials are currently missing. The paper presents a complete catalogue of all the materials currently kept at the archaeological museum P. Giovio di Como. After a brief survey of the history of research on the chronological articulation of the Golasecca culture, the Author proceeds to the typological and chronological study of the pottery and of the bronze sheet cup, of the fibulae, and other objects found inside the urn. The analysis of the burnt bones attributes the tomb to an adult female and this has been confirmed by the grave-goods: the boat-shaped fibulae, the fibulae with amber decorated bow, the openwork pendants (so-called pomegranate pendants), the stop-folds discs and earrings in bronze sheet are all characteristic elements of the female costume. From a chronological point of view, on one hand there are some elements of continuity with phase Golasecca I C, on the other there are more elements of novelty that allow to date the tomb to the beginning of Golasecca II period (phase G. II A)
Simulation of Soil Water Content in Mediterranean Ecosystems by Biogeochemical and Remote Sensing Models
No full textThe current study assesses the potential of two modeling approaches to simulate the daily site water budget in Mediterranean ecosystems. Both models utilize a simplified one-bucket approach but are fed with different drivers. The first model, BIOME-BGC, simulates all main biogeochemical fluxes based on conventional meteorological and ancillary data, while the second uses evapotranspiration estimates derived from the combination of meteorological data and satellite normalized difference vegetation index (NDVI) images. The two models were tested for three Italian sites which are characterized by different vegetation types and ecoclimatic conditions: (i) low mountain coniferous forest; (ii) hilly deciduous forest; (iii) urban grassland. The soil water balance simulated by the two models was evaluated through comparison with daily measurements of soil water content (SWC) taken during a growing season. Satisfactory results were obtained in all cases by both approaches; the SWC estimates are significantly correlated with the measurements (correlation coefficient, r, higher than 0.74), and the mean errors are lower than 0.079 cm3 cm−3. The second model, however, generally shows a higher accuracy, which is dependent on the quality of the NDVI data utilized (r higher than 0.79 and errors lower than 0.059 cm3 cm−3). The study therefore provides useful indications for the application of these and similar simulation methods in different environmental situations

Root Zone Sensors for Irrigation Management in Intensive Agriculture
No full textCrop irrigation uses more than 70% of the world’s water, and thus, improving irrigation efficiency is decisive to sustain the food demand from a fast-growing world population. This objective may be accomplished by cultivating more water-efficient crop species and/or through the application of efficient irrigation systems, which includes the implementation of a suitable method for precise scheduling. At the farm level, irrigation is generally scheduled based on the grower’s experience or on the determination of soil water balance (weather-based method). An alternative approach entails the measurement of soil water status. Expensive and sophisticated root zone sensors (RZS), such as neutron probes, are available for the use of soil and plant scientists, while cheap and practical devices are needed for irrigation management in commercial crops. The paper illustrates the main features of RZS’ (for both soil moisture and salinity) marketed for the irrigation industry and discusses how such sensors may be integrated in a wireless network for computer-controlled irrigation and used for innovative irrigation strategies, such as deficit or dual-water irrigation. The paper also consider the main results of recent or current research works conducted by the authors in Tuscany (Italy) on the irrigation management of container-grown ornamental plants, which is an important agricultural sector in Italy

The role of the syntactic features of similes in their translation from English into Albanian: The case of Thomas Hardy’s Tess of the d’Urbervilles
No full textIt has often been stated in translation theory that afinity between linguistic features in different languages may facilitate their translation from one into the other. Similes are one of these features. Apart from the fact that they usually comprise a tripartite structure, the comparison markers establishing the relationship between the other two constituents happen to be quite close semantically. Similarity may be seen even in the syntactic function that they fulill in the texts where they appear. However, do these syntactic afinities really affect the translation of similes in a positive way? If yes, to what degree? In this paper we set out to investigate these two issues using data from the novel “Tess of the d’Urbervilles” by the British author Thomas Hardy and its translation into Albanian “Tesi i d’Erbervileve”. We will first analyze similes in terms of their syntactic make-up and the functions they fulfill in the source text followed by an analysis of their translations. Finally, we will discuss the implications of these analyses for the issues above

Nuove Tecnologie per il Monitoraggio e la Gestione dei giardini storici
No full textItSotto la spinta dei cambiamenti socio-economici e di significativi progressi tecnici, la gestione dei giardini storici e degli spazi verdi in genere, sta vivendo un periodo di forte cambiamento ed evoluzione. Nel tentativo di razionalizzare l’uso delle risorse naturali e umane, nascono nuovi servizi che fanno intravedere la necessità di creare specifiche figure professionali, in grado di colmare in tempi rapidi il divario tra le potenzialità applicative offerte dalle nuove tecnologie e le diverse realtà operative, ancora legate all’uso di pratiche e metodologie tradizionali. Anche nel settore dei giardini e dei parchi storici è giunto il momento di approfondire i temi relativi alla loro conservazione e valorizzazione, che oggi sono strettamente legati a una concreta sostenibilità economica e ambientale delle pratiche di gestione e di promozione. Queste considerazioni sono state alla base di una serie di iniziative e di progetti promossi a livello nazionale ed europeo, che, grazie all’integrazione di strumenti ICT, SMART-Sensors e IA, in alcuni casi si sono concretizzati nella realizzazione di metodologie e soluzioni di grande interesse operativo.Le procedure e i criteri presentati in questo articolo sono il risultato dell’attività di ricerca e trasferimento tecnologico condotta dal CNR-IBIMET di Firenze negli ultimi dieci anni. Già nella sua versione prototipale, il sistema proposto mostra tutte le sue potenzialità di monitoraggio e supporto alle attività gestionali e manutentive degli spazi verdi, aprendo la strada a una progressiva automazione e virtualizzazione delle procedure (creazione di scenari), elementi essenziali per la successiva valorizzazione e promozione del bene a livello sociale e culturale.In particolare, oltre allo schema logico del sistema, si discutono alcune tra le funzioni di monitoraggio di maggiore interesse (disponibilità idrica, stato fitosanitario e fenologia), evidenziando quali siano i vantaggi concreti degli operatori del settore nel disporre di informazioni integrate a scale spazio-temporali ottimali per le diverse pratiche.EnUnder the pressure of socio-economic changes and technical advances, the management of historical gardens and green spaces is going through a period of significant change and evolution. New and better performing types of services, aiming to rationalize the use of natural and human resources, encourage the creation of specific professional figures able to/who can quickly fill the gap between the potential of the new technologies and the more common practices, still tied to the traditional tools and methodologies. From several points of view, green management needs to explore the opportunity to rationalize interventions and consequently significantly reduce costs and downtime. These were the considerations behind a series of initiatives and projects at national and European level, some of which led to the development and delivery of interesting methodologies and solutions from the integration of ICT tools, SMART-Sensors and IA.Procedures and criteria discussed in this article are the result of research and technology transfer activities carried out in this field by CNR-IBIMET of Florence in the last ten years. The described prototype system already shows its potential for monitoring and supporting management and maintenance of green spaces, opening the way for a progressive virtualization and automation of the procedures (creation of scenarios), an essential step for further social and cultural development and promotion.Some of the monitoring functions of interest for this field (water availability, plant health and phenology) are discussed, trying to clarify the practical benefits to private and public decision makers of having integrated information available at optimized space and time scales.<br/
The use of tensiometers to automatically control the irrigation of ornamental species in containers
No full textThe detection of soil water potential by means of tensiometers is one of the possible techniques to adapt water supply to real plant exigencies, reducing water and nutrient consumption and the environmental impact. The aim of the different experiments illustrated in this paper was the evaluation of tensiometer performances in the automatic control of the irrigation or fertigation of some ornamental species cultivated in containers. Different experiments were carried out over a two-year period on four ornamental species. Three species were cultivated outdoor and equipped with a drop irrigation system while the fourth was cultivated in greenhouse using two different irrigation techniques (drop and subirrigation). In all experiments, tensiometer-based system allowed water or nutrient solution saving ranging from 45% to 25% in comparison with timer-based irrigation management, without negatively affect plant growth and qualitative characteristics. Some arrangements to obtain the best performances of tensiometers in the automatic irrigation management are also illustrated
