INTERVENTI DI POTATURA VERDE PER LA GESTIONE DELLA MATURAZIONE DELL’UVA NELLA CV MERLOT IN AMBIENTE CALDO ARIDO

Considering the predicted scenarios of climate change for the near future, Mediterranean vineyards, may face substantial shifts in precipitation, atmospheric conditions and temperature, resulting in higher winter rainfall, together with drier and hotter summers. All potentially contributing to an uncoupling of technological and phenolic ripeness in Vitis vinifera grapevines, due to berry ripening taking place in the hottest month of the year, resulting in wines with high alcohol content and low titratable acidity. A reduced sugar accumulation rate in the berry may delay berry maturation and subsequently counteract these effects. The aim of this study was to delay berry maturation in cv Merl…

On the relationship between some production parameters and a vegetation index in viticulture

The use and timing of many agronomical practices such as the scheduling of irrigation and harvesting are dependent on accurate vineyard sampling of qualitative and productive parameters. Crop forecasting also depends on the representativeness of vineyard samples during the whole phenological period. This manuscript summarizes the last two years of precision viticulture in Sicily (Italy); agronomic campaigns were carried out in 2012 and 2013 within the "Tenute Rapitalà" and "Donnafugata" farms. Normalized Difference Vegetation Index derived from satellite images (RapidEye) acquired at berry set, pre-veraison and ripening phenological stages (occurred at June, July and August respectively) ha…

Grapevine row orientation mediated temporal and cumulative microclimatic effects on grape berry temperature and composition

Abstract Ambient radiation and temperature are global drivers of grapevine growth, grape yield and composition, and wine quality. Knowledge of the implications of vineyard row orientation/microclimate is required for decision-making in current and future macro- and mesoclimates. Temporal and cumulative microclimatic changes, induced by vine row orientation (NS; EW; NE-SW; NW-SE) of vertically trellised Shiraz grapevines, on berry pulp temperature and composition at different ripeness levels were investigated. Berries dynamically gained heat energy relative to: ambient climate/weather; direct canopy wall/bunch irradiance; and berry skin colour development. Berries exposed to direct solar rad…

Characterization of carob germplasm (Ceratonia siliquaL.) in Sicily

SummarySixteen carob cultivars were studied to evaluate pulp and seed yield with regard to endosperm percentage, to determine the overall degree of polymorphism of the characters and to detect similarities among cultivars. Bean size and numbers of normal and aborted seeds were characters with a certain degree of polymorphism. The low between-year variability observed suggests that differences in the variables could be attributed to genetic factors. A high year-to-year variation was observed only for the number of aborted seeds. Seed characteristics showed small changes both between years and among cultivars. Out of all the variables, PCA identified four principal components that explained m…

Design of complex sheet metal forming processes: a new computer aided progressive approach

The growing interest in sheet metal stamping processes, particularly in automotive industry, led to three main issues in this field: request of very complex shapes; growing interest in springback control; solution of multi-objective problems. This makes the design of the sheet metal stamping processes very difficult, since the number of both design variables and design objectives are progressively increased; therefore, proper design methodologies to reduce times and costs are highly required. In this paper, an innovative design approach able to manage and optimize complex stamping operations is proposed. In particular, a progressive design approach based on the integration between numerical…

Differences among young adults, adults and elderly chronic myeloid leukemia patients

Abstract BACKGROUND: The incidence of chronic myeloid leukemia (CML) increases with age, but it is unclear how the characteristics of the disease vary with age. In children, where CML is very rare, it presents with more aggressive features, including huge splenomegaly, higher cell count and higher blast cell percentage. PATIENTS AND METHODS: To investigate if after childhood the disease maintains or loses these characteristics of aggressiveness, we analyzed 2784 adult patients, at least 18 years old, registered by GIMEMA CML WP over a 40-year period. RESULTS: Young adults (YAs: 18-29 years old) significantly differed from adults (30-59 years old) and elderly patients (at least 60 years old)…

Analysis of stamping performances of dual phase steels: A multi-objective approach to reduce springback and thinning failure

The industrial interest on light weight components has contributed in the last years to a significant research effort on new materials able to guarantee high mechanical properties, good formability and reasonable costs together with reduced weights when compared to traditional mild steels. Among such materials advanced high strength steels (AHSS) such as transformations induced plasticity (TRIP) and dual phase (DP), and light weight alloys proved their usefulness in stamping of automotive components. As AHSS are concerned, one of the main drawbacks is related to springback occurrence. Many aspects have to be taken into account when springback reduction is investigated: material behavior iss…

Linfoma a cellule B (maltoma) dello stomaco ed infezione da Helicobacter pylori

The authors, after illustrating physiopathologic aspects of gastric MALTomas, examine the H.P. infections and the possible relations between this kind of bacterium and gastric MALTomas. They hypothesize that H.P. infection represents an important predisposition to gastric lymphoma, due to anatomopathological modifications over gastric mucosa. They conclude that a decreasing of gastric lymphoma could be correlatable an opportune eradication of H.P. despite of at moment it's impossible hypothesize a marked decreasing of lymphoma by an eradication of H.P.

Influence of mechanical properties of the sheet material on formability in single point incremental forming

Abstract New trends in sheet metal forming are rapidly developing and several new forming processes have been proposed to accomplish the goals of flexibility and cost reduction. Among them single point incremental forming operations, in which the final shape of the component is obtained by the relative movement of a simple and small punch with respect to the blank, appear quite promising. In the paper, material formability issues in incremental forming were studied. Some relevant correlations among material formability and other mechanical properties of the material were analysed. The FLD 0 value, i.e. the major strain at fracture in plane strain conditions, was determined for different mat…

Upscaling leaf gas exchange measurements to the whole grapevine canopy: An update

This review first revisits current knowledge about single-leaf function, viz. photosynthesis, chiefly in relation to environmental factors, that underscores the importance of multiple summer stresses. Emphasis is placed on the response different genotypes show under light and heat stress with or without soil-water shortage. Secondly, it tackles the thorny issue of extrapolating single-leaf readings to the whole-canopy level, with special reference to both methodological and physiological implications. Whole-canopy gas-exchange systems deliver and emphasise the usefulness of such an approach in achieving key research goals. One case in point is quantifying the amount and dynamics of canopy g…

Hot Impression Die Forging Process: An Approach to Flash Design for Tool Life Improvement

In impression die forging the role of the flash geometry is fundamental since a proper design of the flash land strongly influences both the complete die filling and the die wear (i.e. the die life and the related costs). In this paper an integrated approach between numerical simulations and statistical tools was developed with the aim to optimize flash thickness in order to reduce die wear and to minimize material wasting. As wear is regarded, an analytical model depending on sliding velocity, temperature, die hardness and contact pressure was utilized during the numerical simulations of the process in order to reach a wear evaluation for different values of the flash design variables. Thu…

Process parameters calibration in 3D tube hydroforming processes

In tube hydroforming the concurrent actions of pressurized fluid and mechanical feeding allow to obtain tube shapes characterized by complex geometries such as different diameters sections and/or bulged zones. What is crucial in such processes is the proper design of operative parameters aimed to avoid defects (for instance shape defects or ductile fractures). The main process parameters are material feeding history (i.e. the punches velocity history) and internal pressure path during the process. In more complex three dimensional processes, also the action of a counterpunch is generally useful to reduce thinning in particular in expansion zones of the tube (i.e. T or Y shaped tubes). The g…

Guidelines to compare additive and subtractive manufacturing approaches under the energy demand perspective

In order to characterise the environmental performance of additive manufacturing (AM) processes, comparative analyses are required. Different manufacturing approaches (such as additive and subtractive ones), besides adopting different equipment, use different kinds and amounts of material. Therefore, the material-related flow has to be followed throughout the entire product life. Differences in environmental impact arise at each step of the life cycle: material production, manufacturing, use, disposal, and transportation. A life cycle-based methodology able to take due account of all the factors of influence on the total energy demand for the production of metal components is given in this …

EFFECT OF TIPPING AND TOPPING ON SHOOT UNIFORMITY: PRELIMINARY RESULTS ON SINGLE CORDON TRAINED CABERNET SAUVIGNON AND MERLOT

The study was carried out in a two year old Merlot/140 Ru and Cabernet Sauvignon/140 Ru vineyards during the 2004 growth season. Vines were spaced 2.4 m x 0.9 m in North-South orientated rows. Each vine had five to six shoots. The vineyards were drip irrigated (800 m3/Ha/season). Shoots more than 100 cm were tipped or topped at pea berry size development stage. Tipping of Merlot vines reduced shoot growth and variability of all vegetative parameters. Topping of Cabernet Sauvignon reduced variability of shoot Diameter and increased lateral shoot growth.

Optimal die Design for Cold Extrusion Processes

The design of cold extrusion processes requires the optimisation of several process variables in order to obtain a defect free product. The fulfilment of different objectives, such as the minimisation of forming loads or the homogeneity of the deformations, is highly requested. Nevertheless, several other relevant aspects of extrusion processes have to be taken into account and require a suitable optimisation of the process parameters and in particular of the die shape. In this paper, tool life has been assumed as the most relevant goal and an effective die design procedure as been setup. It is well known that fatigue cracking of the dies is the principal cause of dies failure in cold extru…

Somatic embryogenesis of Vitis vinifera L. (cv Sugraone) from stigma and style culture

Somatic embryo and plant regeneration were induced from stigma and style culture of grapevine (Vitis vinifera L. cv. Sugraone). To obtain somatic embryogenesis, explants were cultured on Nitsch and Nitsch basal medium (NN) supplemented with 88 mM sucrose and various combinations of the auxin β-naphthoxyacetic acid (NOA, 0-10 μM) and the cytokinin 6-benzylaminopurine (BA, 0-9 μM). Growth regulators (BA and NOA) in the culture medium were essential for induction of somatic embryogenesis since explants incubated on hormone-free medium never regenerated somatic embryos. Usually, the regenerated somatic embryos become visible as small white globular structures on the surface of the callus 3-4 mo…

Anthocyanin variation in individual 'Shiraz' berries as affected by exposure and position on the rachis

This study was done on 'Shiraz'/Richter 99 grapes with the intention to define the variation of skin anthocyanin content in a single berry. The effects of berry position (on the rachis), berry exposure, berry weight category, part of the skin of a single berry, and their interactions, were analysed. The anthocyanin concentration of externally facing berries decreased and that of the internally facing berries increased from the apical part to the basal part of the bunch. Highest values were recorded in internally facing berries and lowest values in the externally facing (exposed) berries, of the basal rachis area. Anthocyanin values of small berries seemed to decrease from the apical part of…

Evaluation of graft success of grapevine after incubation room by means of thermographic, electrical and mechanical techniques

Grafting is an important technique for getting good yields in plant multiplication. Understanding the success of the graft after the incubation stage is important to the evaluation of the suitable grafting for the open field (nursery). Successful grafting in vines requires the development of a functional vascular system between the scion and the rootstock. The graft compatibility and its augmentation depend upon various natural factors like environment, soil conditions and protective measures. The present study examines the capability of thermographic, mechanical and electrical techniques to assess the graft quality and success after the incubation stage. The trial was carried out at Vivai …

An integrated approach to the design of tube hydroforming processes: artificial intelligence, numerical analysis and experimental investigation

In the last years, the growing role of process flexibility in modern mechanical industries has driven a rising interest in optimisation of process/product design through innovative techniques. Moreover, the development of niche productions, which are characterised by low production volumes and small batches leads to the need of more flexible and rapid forming technologies. In this way, a great research effort is performed towards the study of new stamping processes: among them hydro forming finds a large interest in automotive industry since it allows to significantly reduce tooling costs and also to avoid some secondary operations. Different studies are available in the technical literatur…

For three dimensional tube hydroforming operations (i.e. T or Y shaped tubes) the calibration of both material feeding history and internal pressure path during the process is crucial and many approaches to such optimization were presented; the authors developed some procedures to optimize pressure paths and punch velocity histories with the application of an integrated method FEM - Gradient based optimization tools. In this paper, an experimental validation campaign of the utilized optimization strategies is presented with the aim to assess the effectiveness of the developed procedures. An optimization procedure (gradient based techniques) was applied on the process parameters leading to t…

A methodology for the environmental comparison of metal shaping technologies: an in-depth analysis on recycling related issues

The reduction of CO2 emissions is an urgent objective to pursue. The scientific and the industrial world have gathered such challenge, starting to find out energy- and resource-efficient manufacturing strategies. From the literature review, in the domain of environmental impact analysis of manufacturing processes, two relevant knowledge gaps can be spotted: (1) the metal forming processes (and, in particular, the bulk forming processes) are still not well documented, and (2) there is a lack of systematic and comparative studies on energy and material flows enabling the identification of environmentally-friendly manufacturing design strategies. This research offers a contribution to a better…

Design of sheet stamping operations to control springback and thinning: a multi-objective stochastic optimization approach

Abstract The aim of this paper is to develop a design tool for stamping processes, which is able to deal with the scattering of the final part quality due to the inner variability of such operations. Such variability is one of the main drawbacks for a robust process design. It results in a scattering of the most significant process results and depends on several parameters. The so called noise factors greatly influence final result variability, which often means rejecting parts and anyway achieving final properties different from the specified ones. The process investigated in the paper is an S-shaped U-channel stamping operation carried out on a lightweight aluminum alloy of automotive int…

Berries variability: causes and effects on the quality of ‘Cabernet Sauvignon’

In this study the objective was to investigate if differences in berry size (within a population of berries from different bunches) and flowering process would lead to differences in qualitative parameters and berries variability. The trial was conducted during the 2009 vegetative season at an irrigated ‘Cabernet Sauvignon’/1103 P vineyard. At the beginning of flowering, for 100 inflorescences, all open flowers were marked by red ink while 5 days later, closed flowers were marked by black ink. Open and closed flower distribution was investigated along the rachis. At pea size, 20 marked bunches were sampled. The diameter and weight of all berries was measured and Gaussian distribution was pe…

The use of vineyard spectral signatures to identify table grape cultivars

Vineyards have characteristic responses to sunlight. The reflectance values at the different wavelengths are typical of vegetation and define its spectral signature. The aim of this work was to determine the spectral signatures of table grape vineyards located in the production area of Robinvale (Victoria, Australia) in order to identify cultivars in the vineyard. Spectral signatures were detected from images in eight bands from the Worldview 3 platform. Spectral signatures for a representative number of plots were extracted using satellite reflectance images for each cultivar. Spectral signatures were also collected in the field, from the same cultivars, with a FieldSpec® HandHeld 2 portab…

A Comparative Analysis of Different Robust Design Approaches in Sheet Stamping Operations

A crucial issue in sheet stamping optimization problems is related to the process robustness improvement: critical scattering in the investigated performances arises due to some noise variables influence, often evolving up design failure itself. In fact, strong variations in the final stamped part or fluctuations of strain distribution may lead to an uncontrolled process design. Such variability cannot be controlled but anyway it is possible to develop proper design tools able to identify robust process calibrations above which the noises variations effects are admissible. In this paper, a multi‐objective optimization problem was analyzed, with the aim to minimize both excessive thinning an…

An Inverse Approach for the Design of the Optimal Preform Shape in Cold Forging

Abstract In closed die forging the preform design plays a critical role for the success of the process: in fact it must ensure that in the finishing step the desired product is obtained without shape defects such as underfilling or folding and with a minimum material loss into the flash. In the paper an inverse approach is applied to the preform shape optimization problem: the method permits to evaluate a response function which links the set of parameters defining the preform shape with the fulfillment of the product design specifications. The proposed approach has been applied to a closed die forging process aimed to the production of a C-shape component, and has allowed to determine the …

In this paper, a comparison between a traditional deep drawing and an single point incremental forming process is investigate…

Sustainability issues in sheet metal forming processes: an overview

Abstract Environmental sustainability in manufacturing is nowadays an urgent and remarkable issue and the main concerns are related to more efficient use of materials and energy. In sheet metal forming processes there is still a lack of knowledge in this field mainly due to the need of a proper modelling of sustainability issues and factors to be taken into account. The aim of this paper is mainly to underline the state of the art from a forming point of view about the sustainability contributions offered in any phase of a product life cycle. Actually, a lack in terms of comprehensive contributions is present in the technical literature, thus, the authors try to give a sort of holistic visi…

A sensitivity analysis on environmental sustainability in sheet metal forming

An experimental campaign to investigate sustainability issues in Single Point Incremental Forming processes

Sustainability issues are crucial topics in manufacturing and the environmental burdens reduction for processes is highly requested. In particular, the environmental sustainability evaluation for sheet metal forming processes is an widely investigated topic since there is still a lack of knowledge on modeling issues. The main tasks are related to a more efficient materials use and to energy savings. Moreover, forming technologies environmental impacts are essentially process-dependent. A deep analysis of the cause-effect linkages (between process and material parameters and energy consumption, for instance), within each process, would be necessary to properly model environmental impacts and…

Optimal Blankholder Force Path in Sheet Metal Forming Processes: An Al Based Procedure

Abstract Blankholder force plays a fundamental role in the deep drawing process mechanics since it controls, by friction, the material flow into the die cavity. The availability of computer controlled hydraulic presses in the industries promoted a new research field focused on the definition of optimal BHF histories, function of the punch displacement; such studies were aimed to the determination of the so called “process window”, i.e. the BHF path which permits to obtain the maximum height sound component avoiding both wrinkling and tearing. In the paper a design procedure is proposed in order to determine the optimal BHF path in an axisymmetric deep drawing process: in particular, a close…

Berry characterisation of cv shiraz according to position on the rachis

In this study, characterisation of the physical and compositional parameters of berries located in different positions on the rachis of Shiraz/R99 bunches was done. Berries were divided according to position on the rachis (apical, median and basal) and berry weight, resulting in four berry weight classes, averaging 0.86 g, 1.29 g, 1.74 g and 2.26 g and 0.74, 1.18, 1.59 and 2.09 cm3, respectively. The berries were analysed individually. The fresh weight of the berries comprised approximately 4% seeds, 20% skin and 76% flesh. Different percentage distributions were found for each class of berry weight and according to position on the rachis. From the top to the bottom rachis position, an incr…

Optimal design of tube hydroforming processes: A fuzzy-logic-based approach

In recent years, tube hydroforming has become an economic and industrially suitable alternative to various traditional stamping processes, in particular for small batch production. In the present paper, an artificial intelligence system based on fuzzy logic was implemented for tube hydroforming process design. The aim was to achieve a process design procedure able to prevent forming defects and guarantee the achievement of the desired final shape of the component. In particular, the process design concerns the internal pressure history and the axial feeding. The fuzzy system is able to provide optimal trajectories for both the controlled parameters, producing a defect-free final part.

Development of a Design Procedure for Bending Operations

Springback can be considered as one of the most important shape defect in sheet stamping. Such effect results relevant even when simple bending operations are taken into account. In the paper the authors present a design procedure able to provide the proper value of the punch stroke to be applied in order to compensate for elastic springback. In particular two approaches have been followed: firstly an inverse design technique has been utilized in order to find out the response function governing the investigated phenomenon; furthermore neural network techniques have been applied in order to represent the logical link between the input data and the aimed output, i.e. the proper punch stroke …

Comparison of analytical methods and AI tools for material characterisation in hot forming

Abstract Hot forming processes probably represent the most ancient of forming operations and what is more they are still today commonly used in modern mechanical industry in order to obtain sound parts, achieving large deformations with a limited required power. Hot metal forming operations are characterised by a large number of physical and thermal phenomena which have to be taken into account in order to model and design the processes themselves. Actually several thermally activated phenomena occur during the forming processes such as recovery, recrystallisation, grain growth, precipitation, allotropic transformations, etc. In this paper the comparison between an analytical method based o…
