Effects of partial rootzone drying and rootstock vigour on growth and fruit quality of 'Pink Lady' apple trees in Mediterranean environments
2008
We investigated the effects of partial rootzone drying (PRD) and rootstock vigour on water relations, and vegetative and productive performance of ‘Pink Lady’ apple (Malus domestica Borkh.) trees in central Sicily. In a first field trial, trees on MM.106 rootstock were subjected to: Conventional irrigation (CI), maintaining soil moisture above 80% of field capacity; PRD irrigation, where only one alternated side of the rootzone received 50% of the CI irrigation water; and continuous deficit irrigation (DI), where 50% of the CI water was equally applied to both sides of the rootzone. In a second trial, trees on M.9 or MM.106 were subjected to CI and PRD irrigation. PRD reduced stomatal condu…
Diurnal Regulation of Leaf Water Status in High- and Low-Mannitol Olive Cultivars
2014
The role of mannitol and malic acid in the regulation of diurnal leaf water relations was investigated in ‘Biancolilla’ (high-mannitol) and ‘Cerasuola’ (low-mannitol) olive trees. Photosynthetic photon flux density (PPFD), vapor pressure deficit (VPD), stomatal conductance (gs), transpiration rate (T), relative water content (RWC), mannitol and malic acid were measured in ‘Biancolilla’ and ‘Cerasuola’ leaves during a dry and hot day of summer in Sicily. In general, leaves of ‘Biancolilla’ trees exhibited greater mannitol content, higher gs and T, but lower RWC than leaves of ‘Cerasuola’ trees. Differences in gs and T between the two cultivars were evident mainly in mid to late morning. ‘Bia…
Marinifilum flexuosum sp. nov., a new Bacteroidetes isolated from coastal Mediterranean Sea water and emended description of the genus Marinifilum Na…
2012
Abstract A facultatively anaerobe, moderately halophilic, Gram-negative, filamentous, non motile and unpigmented bacterium, designated M30 T , was isolated from coastal Mediterranean Sea water in Valencia, Spain. Phylogenetic analysis based on 16S rRNA sequences placed this strain in the phylum “ Bacteroidetes ” with Marinifilum fragile JC2469 T as its closest relative with 97% sequence similarity. Average nucleotide identity (ANI) values between both strains were far below the 95% threshold value for species delineation (about 89% using BLAST and about 90% using MUMmer). A comprehensive polyphasic study, including morphological, biochemical, physiological, chemotaxonomic and phylogenetic d…
Flexible strategic planning of transport systems
2012
Abstract This paper presents a decision support methodology for long-range planning of transport systems that exhibits strategic flexibility and stochastic system parameters. Unlike one-off strategic decisions, flexible decisions should be dynamically reformulated with time. The proposed methodology is based on the construction of a tree structure of multiple interlinked tactical planning problems, each associated with a scenario in the tree, where problems under scenarios at intermediate dates incorporate in their formulation the solution of the corresponding problems associated with past (future) connected scenarios. The resulting tree structure of interconnected planning decisions become…
Forme del fritto: alcune esperienze di consumo
2020
Questo capitolo propone uno studio sul campo di una pratica alimentare che caratterizza la Sicilia e, in particolare, la città di Palermo: lo street food. Lo street food palermitano si caratterizza per essere indissolubilmente legato alla frittura, una modalità di cottura pervasiva tanto nei mercati storici della città, quanto in quei luoghi chiusi che, in forme diverse, tentano di replicarne l'esperienza. Il fritto è, ancor prima che una modalità di cottura dei cibi, un particolare dispositivo ambientale e sensoriale, che pregiudica olfattivamente gli spazi di vendita e consumo e che spinge, alcuni format di distribuzione, a limitarne la pervasività. Vedremo, in questo senso, come la diffe…
Il passato nel presente. Triumphs and Laments di William Kentridge nella lettura di Salvatore Settis (passando per un’Iliade teatrale)
2021
La lettura di Incursioni, recente volume di Salvatore Settis, riporta alla memoria di Gabriella De Marco il potente allestimento dell’Iliade messo in scena dal Teatro del Carretto, per l’adattamento e la regia di Maria Grazia Cipriani. Il rapporto di continuità nelle arti, con la memoria dell’antico, con il passato, con la tradizione diventa una sorta di fil rouge che guida la ricerca di Settis. Tra gli spunti di Incursioni vi è la certezza, che “tra antico e contemporaneo non c’è netta frattura, ma una perpetua tensione, che, continuamente si riarticola nel fluire dei linguaggi” . La mise en scène del Teatro del Carretto stabilisce un rapporto con la memoria del passato inteso non come un …
Concept and History of the Serial Killer
2001
Some murderers kill three or more victims, with a certain cooling-off period between them. These are the so-called “serial killers.” John Wayne Gacy, Jose Antonio Rodriguez Vega, and Christa Lehmann are three such cases.
Voltage Security Assessment by Using PFDT and CBR Methods in Emerging Power System
2018
Abstract This paper exhibits varied methods for voltage security assessment in a restructured power system. This paper primarily lays emphasis on two methods that are Probabilistic Fuzzy Decision Tree (PFDT) and Case Based Reasoning (CBR). In PFDT, Decision Tree plays an integral role for classification of system. For further classification of power system security, an algorithm is developed to categorise the buses which trouble the security most. After classification of system, by using minimum amount of load curtailment of voltages on buses which made insecure to secure load. Optimization of load is done by curtailing reactive power from insecure buses. In CBR, old cases from database are…
TB-Structure: Collective Intelligence for Exploratory Keyword Search
2017
In this paper we address an exploratory search challenge by presenting a new (structure-driven) collaborative filtering technique. The aim is to increase search effectiveness by predicting implicit seeker’s intents at an early stage of the search process. This is achieved by uncovering behavioral patterns within large datasets of preserved collective search experience. We apply a specific tree-based data structure called a TB (There-and-Back) structure for compact storage of search history in the form of merged query trails – sequences of queries approaching iteratively a seeker’s goal. The organization of TB-structures allows inferring new implicit trails for the prediction of a seeker’s i…
A Concept for Quantitative Comparison of Mathematical and Natural Language and its possible Effect on Learning
2017
Starting with the question whether there is a connection between the mathematical capabilities of a person and his or her mother tongue, we introduce a new modeling approach to quantitatively compare natural languages with mathematical language. The question arises from educational assessment studies that indicate such a relation. Texts written in natural languages can be deconstructed into a dependence graph, in simple cases a dependence tree. The same kind of deconstruction is also possible for mathematical texts. This gives an idea of how to quantitatively compare mathematical and natural language. To that end, we develop algorithms to define the distance between graphs. In this paper, w…
