Oil recovery for fractured-vuggy carbonate reservoirs by cyclic water huff and puff: performance analysis and prediction
Authors: Wang Daigang , Sun Jingjing
Published: October 2019

Cyclic water huff and puff (CWHP) has proven to be an attractive alternative to improve oil production performance after depletion-drive recovery in fractured-vuggy carbonate reservoirs. However, due to the impact of strong heterogeneity, multiple types of fractured-vuggy medium, poor connectivity, complex flow behaviors and oil-water relationship, CWHP is merely suitable for specific types of natural fractured-vuggy medium, usually causing a great difference in actual oil-yielding effect. It remains a great challenge for accurate evaluation of CWHP adaptability and quantitative prediction of production performance in fractured-vuggy carbonate reservoir, which severely restricts the application of CWHP. For this study, we firstly enable the newly developed fuzzy grey relational analysis to quantify the adaptability of CWHP. With production history of several targeted producers, the accuracy of the proposed method is validated. Based on the traditional percolation theory and waterflood mechanisms in various types of fractured-vuggy medium, a quantitative prediction model for cyclic water cut fwp and increased recovery factor ΔR is presented. The CWHP production performance is discussed by using the Levenberg-Marquardt algorithm for history matching. With a better understanding of the fwp ~ ΔR curve characteristics in different types of fractured-vuggy medium, proper strategies or measures for potential-tapping remaining oil are provided. This methodology can also offer a good basis for engineers and geologists to develop other similar reservoirs with high efficiency.

Characterization of the Importin-β binding domain in nuclear import receptor KPNA7
Authors: Oostdyk Luke T. , McConnell Michael J. , Paschal Bryce M.
Published: October 2019

The KPNA family of mammalian nuclear import receptors are encoded by seven genes that generate isoforms with 42–86% identity. KPNA isoforms have the same protein architecture and share the functional property of nuclear localization signal (NLS) recognition, however, the tissue and developmental expression patterns of these receptors raise the question of whether subtle differences in KPNA isoforms might be important in specific biological contexts. Here, we show that KPNA7, an isoform with expression mostly limited to early development, can bind Importin-β (Imp-β) in the absence of NLS cargo. This result contrasts with Imp-β interactions with other KPNA family members, where affinity is regulated by NLS cargo as part of a cooperative binding mechanism. The Imp-β binding (IBB) domain, which is highly conserved in all KPNA family members, generally serves to occlude the NLS binding groove and maintain the receptor in an auto-inhibited ‘closed’ state prior to NLS contact. Cooperative binding of NLS cargo and Imp-β to KPNA results in an ‘open'state. Characterization of KPNA2–KPNA7 chimeric proteins suggests that features of both the IBB domain and the core structure of the receptor contribute to the extent of IBB domain accessibility for Imp-β binding, which likely reflects an ‘open’ state. We also provide evidence that KPNA7 maintains an open-state in the nucleus. We speculate that KPNA7 could function within the nucleus by interacting with NLS-containing proteins.

Authors: Xu Cai-Ming , Luo Ya-Lan , Li Shuai , Li Zhao-Xia , Jiang Liu , Zhang Gui-Xin , Owusu Lawrence , Chen Hai-Long
Published: October 2019

Neuron-specific enolase (NSE), also known as gamma (γ) enolase or enolase-2 (Eno2), is a form of glycolytic enolase isozyme and is considered a multifunctional protein. NSE is mainly expressed in the cytoplasm of neurons and neuroendocrine cells, especially in those of the amine precursor uptake and decarboxylation (APUD) lineage such as pituitary, thyroid, pancreas, intestine and lung. In addition to its well-established glycolysis function in the cytoplasm, changes in cell localization and differential expression of NSE are also associated with several pathologies such as infection, inflammation, autoimmune diseases and cancer. This article mainly discusses the role and diagnostic potential of NSE in some lung diseases.
The fitness challenge of studying molecular adaptation
Authors: Coombes David , Moir James W.B. , Poole Anthony M. , Cooper Tim F. , Dobson Renwick C.J.
Published: October 2019

Advances in bioinformatics and high-throughput genetic analysis increasingly allow us to predict the genetic basis of adaptive traits. These predictions can be tested and confirmed, but the molecular-level changes — i.e. the molecular adaptation — that link genetic differences to organism fitness remain generally unknown. In recent years, a series of studies have started to unpick the mechanisms of adaptation at the molecular level. In particular, this work has examined how changes in protein function, activity, and regulation cause improved organismal fitness. Key to addressing molecular adaptations is identifying systems and designing experiments that integrate changes in the genome, protein chemistry (molecular phenotype), and fitness. Knowledge of the molecular changes underpinning adaptations allow new insight into the constraints on, and repeatability of adaptations, and of the basis of non-additive interactions between adaptive mutations. Here we critically discuss a series of studies that examine the molecular-level adaptations that connect genetic changes and fitness.
IoT‐enabled dependable control for solar energy harvesting in smart buildings
Authors: Ha Quang , Phung Manh Duong
Published: October 2019

Efficiency and reliability have been essential requirements for energy generation in smart cities. This study presents the design and development of dependable control schemes for microgrid management, which can be seamlessly integrated into the management system of smart buildings. Here, to recover from failures in the solar energy system of a building microgrid, dependable controllers are proposed along with their hardware implementation. The system features the use of Internet of Things (IoT) as its core to coordinate the operation of multiple subsystems in a scalable manner. The control scheme uses a number of controllers cooperatively functioning via a token‐based mechanism within the network to provide redundancy and thus reliability in solar tracking. The system exploits data from not only local in‐situ sensors but also online sources via IoT networks for fault‐tolerant control. Experiments conducted in a 12‐storey building indicate that the harvested solar energy meets the design requirement while the control reliability is maintained in face of communication or hardware disruptions. The results confirmed the validity of the proposed approach and its applicability to energy management in smart buildings.
Agent‐based system to control the air‐conditioner and EV charging for residents in smart cities
Authors: Singh Shashank , Namboodiri Aryesh , Selvan Manickavasagam Parvathy
Published: October 2019

Air‐conditioner (AC) accounts for a significant share of residential energy consumption. Considering the widespread rise in electric vehicle (EV) usage, its charging would also contribute a considerable percentage of consumer's total energy consumption. Consequently, the concurrent operation of AC and EV charging would result in peaky load curves. Hence, this study proposes a system of agents for AC and EV charging applications, which incorporates load‐management strategies to flatten the load curve. Thereby, the presented system includes two agents, namely: a smart load node for a thermostatically controlled load (SLN‐TCL) and a smart battery charge controller. Subsequently, a subagent, namely micro‐node, has been introduced to support SLN‐TCL and to implement the concept of distributed temperature sensing (DTS). The implementation of DTS subdues the conventional temperature sensing mechanism of AC and ensures a more flexible operation. This study includes the design, development, and features of agents and subagents for AC and EV applications. Furthermore, this study also demonstrates the agent‐based control actions for peak‐shaving under real conditions to showcase the performance of this system.
Experimental and finite element studies of a 250 kW brushless doubly fed induction generator
Authors: Abdi Salman , Abdi Ehsan , McMahon Richard
Published: October 2019

This study studies, using experimentally verified finite element (FE) analysis, various performance measures of the brushless doubly fed induction generator (BDFIG) when magnetic wedges are used for closing stator open slots. The BDFIG is an attractive generator solution for offshore wind power and can replace doubly fed slip‐ring induction generators. It is shown in this study that the use of magnetic wedges, commonly used in large induction machines, reduces the stator windings magnetising currents in a BDFIG, reflected in the values of magnetising inductances. They also increase the leakage flux in the stator slots, leading to a larger series inductance in the equivalent circuit. The series inductance significantly affects the BDFIG performance as well as the rating of its converter. The effects of magnetic wedges on BDFIG air‐gap flux, synchronous torque, and stator tooth top saturation is also investigated. Two‐dimensional FE analysis of an experimental 250 kW BDFIG is used in this study, verified by experimental measurements.
Research on reliability comprehensive evaluation method of five‐axis CNC machine tools based on AHP and extension theory
Authors: Wang Pengjia , Wang Hongjun , Chen Xiumei
Published: October 2019

Currently, some five‐axis CNC machine tools have almost achieved the same advanced level of the western countries in terms of functionality and performance. However, the reliability of system is much lower than similar foreign products. The reliability has become one of bottlenecks to restrict the development of domestic CNC machine tools. At present, domestic reliability research of CNC machine tools developed rapidly, but the evaluation research is limited to a single indicator, lacking overall evaluation about it. To fully evaluate the reliability of five‐axis CNC machine tools, the matter‐element model of reliability evaluation is established with the application of matter‐element in extension theory, and the reliability evaluation indices system is established comprehensively. The correlation functions are introduced to calculate the correlation degree, and the weights of each evaluation indices are determined by using AHP. The actual example and result on two types of domestic CNC machine tools show that the proposed method is effective, reasonable, and accurate in the process of reliability evaluation. The proposed methodology provides a detailed instruction for comprehensive reliability evaluation of CNC machine tools.

Authors: Boya Zhao , Baojun Zhao , Linbo Tang , Chen Wu
Published: October 2019

The deep neural networks has been developed fast and shown great successes in many significant fields, such as smart surveillance, self‐driving and face recognition. The detection of the object with multi‐scale and multi‐aspect‐ratio is still the key problem. In this study, the authors propose a bottom‐up feature pyramid network, coordinating with multi‐scale feature representation and multi‐aspect‐ratio anchor generation. Firstly, the multi‐scale feature representation is formed by a set of fully convolutional layers which is catenated after the backbone network. Secondly, in order to link the multi‐scale feature, the deconvolutional layer is involving after each multi‐scale feature map. Thirdly, to tackle the problem of adopting object with different aspect ratios, the anchors on each multi‐scale feature map are generated by six shapes. The proposed method is evaluated on PASCAL visual object detection dataset and reach the accuracy of 80.5%.
Through‐the‐wall radar sparse imaging for building walls
Authors: Jifang Zhao , Liangnian Jin , Qinghua Liu
Published: October 2019

In through‐the‐wall radar imaging, compressed sensing techniques have been applicable for small amount of observations to reconstruction walls or targets imaging in the scenes. The authors consider building walls imaging. The proposed approach exploits a low‐rank and sparse model to extract the wall returns from radar signals, and then minimises the total variation regularisation problem for reconstructing building walls imaging using the sparsity of their spatial variations. The results of simulation exhibit that the proposed approach effectively enhances the imaging quality of building walls.
Image restoration based on adaptive switching between synthesis and analysis sparse regularisation
Authors: Chen Huahua , Xue Jiling , Lu Yu , Guo Chunsheng
Published: October 2019

Both synthesis and analysis sparse regularisation have been successfully applied to solve various inverse vision problems. The authors find an optimisation model to combine the power of the dual sparse prior models for image restoration. Specifically, for each local patch, adaptive switching on using synthesis or analysis sparse regularisation is performed for better restoration quality. In addition, cluster‐specific synthesis and analysis sub‐dictionary learning, based on principal component analysis method and sequential minimal eigenvalues algorithm, is incorporated into the joint sparse models to achieve maximum indices gains. The efficient alternating strategy is exploited to solve the optimisation problem. Experimental results highlight the superiority of the proposed approach compared with the state‐of‐the‐art methods, especially in terms of better image structures preservation.
Deep template matching for offline handwritten Chinese character recognition
Authors: Li Zhiyuan , Xiao Yi , Wu Qi , Jin Min , Lu Huaxiang
Published: October 2019

Just like its remarkable achievements in many computer vision tasks, the convolutional neural networks provide an end‐to‐end solution in handwritten Chinese character recognition (HCCR) with great success. However, the process of learning discriminative features for image recognition is difficult in cases where little data is available. In this study, the authors propose a novel method for learning siamese neural network which employs a special structure to predict the similarity between handwritten Chinese characters and template images. The optimisation of siamese neural network can be treated as a simple binary classification problem. When the training process finished, the powerful discriminative features will help to generalise the predictive power not just to new data, but to entirely new classes that never appear in the training set. Experiments performed on the ICDAR‐2013 offline HCCR datasets have shown that the proposed method has a very promising generalisation ability for new classes that never appear in the training set.

Published: October 2019

A heat transfer simulation method to obtain the temperature distribution law of asphalt pavement during microwave hot recycling is proposed in this study. The heat transfer form and simulation steps in microwave hot recycling for asphalt pavement are analysed. Heat transfer simulations are conducted on asphalt pavements with different thicknesses and initial moisture contents. It is found that the temperature field of asphalt pavement is closely related to the thickness and initial moisture content of the asphalt pavement. These research results can simulate the hot recycling process on site and offer guiding significance for improving the distribution of the recycling temperature field of asphalt pavement.
Native insectary plants support populations of predatory arthropods for Australian vineyards
Authors: Retallack M. , Thomson L. , Keller M.
Published: October 2019

We provide a summary of two recent studies that investigated the role that three native insectary plants can play in promoting predatory arthropods, and thereby to enhance biological control of vineyard pests in Australia. Native plants are preferred as supplementary flora, as they are locally-adapted to Australia's climatic conditions. Stands of mature Bursaria spinosa, Leptospermum continentale and Rytidosperma ssp. located adjacent to, or in vineyards, in South Australia were sampled for arthropods in 2013/14. Grapevines were also sampled to explore relationships between each plant and associated arthropods using common diversity indices. Twenty seven thousand and ninety-one individual invertebrate specimens were collected, comprising 20 orders and 287 morphospecies. These were categorised into functional groups of predators, herbivores and other. Predatory arthropods dominated the diversity of morphospecies present on each plant. The richness of predator morphospecies across all plant types was nearly double the number found in association with grapevines. It may be possible to increase the functional diversity of predatory arthropods by more than 3x when either B. spinosa or L. continentale is present versus grapevines only, and increase the net number of predator morphospecies by around 27% when Rytidosperma ssp. are planted in combination with grapevines. The selected plants provide a suitable habitat to support diverse and functional populations of predatory arthropods. The opportunity to plant selected native insectary species could help wine grape growers save time and resources by producing fruit with lower pest incidence, while enhancing biodiversity associated with vineyards.

Une alternative aux traitements phytosanitaires pour lutter contre le mildiou et l'oïdium de la vigne est le développement de variétés résistantes. Leur création doit intégrer non seulement le niveau de résistance mais également sa durabilité, ainsi que les performances agronomiques notamment la productivité et la composition des baies qui doit convenir à la production de vins de haute qualité. L'Inra (France) a engagé le programme de sélection ResDur, basé sur le pyramidage des facteurs de résistance, en 2000. Il a conduit à l'inscription au catalogue français d'une première série de variétés à résistance polygénique – Artaban, Floreal, Vidoc, Voltis – en 2018. Agroscope (Suisse) a démarré la création de variétés résistantes en 1996, en mobilisant les résistances portées par des variétés allemandes, principalement Bronner. Un premier aboutissement a été l'homologation en Suisse de Divico et Divona, respectivement en 2013 et 2018. En 2009 l'Inra et Agroscope ont démarré un programme de sélection commun, visant à combiner les facteurs de résistance aux maladies présents de manière complémentaire dans leurs lignées respectives. Les croisements réalisés ont généré, après sélection assistée par marqueurs, 400 descendants porteurs des facteurs de résistanceRpv1, Rpv10 et/ou Rpv3 ; Run1, Ren3 et/ou Ren3.2. Leur phénotypage agronomique et œnologique est réalisé dans le cadre d'un réseau d'essais situés dans les deux Instituts à Colmar (FR) et à Pully (CH). Les premières observations pluriannuelles, portant sur 80 descendants, ont permis d'étudier leur stabilité phénotypique pour les caractères de résistance, les traits culturaux et la qualité des vins. A l'issue de cette étape, quinze variétés candidates ont été sélectionnées et installées en essais d'évaluation de leur valeur agronomique, technologique et environnementale (VATE) en Valais (CH), ainsi que dans trois régions françaises (Champagne, Val de Loire, Vallée du Rhône). L'inscription au catalogue des premières co-obtentions Inra/Agroscope est prévue à l'horizon 2024–2025.

Published: October 2019

En Colombia, la vid se puede considerar como un cultivo promisorio en la era del postconflicto. En esta investigación se evaluó la adaptación de más de cincuenta variedades de vid resistentes a las enfermedades, híbridos productores directos (HPDs) y cruces interespecíficos bajo condiciones tropicales, con el enfoque de encontrar variedades con resistencia para soportar los ataques de Plasmopara viticola, Guignardia bidwelii, Phomopsis viticola, Botrytis cinerea, Uncinula necator, entre otras; así como sus cualidades productivas y de calidad. Otra meta es reducir el número de aplicaciones de agroquimicos por periodo productivo y así lograr que la vid sea un cultivo más amigable con el medio ambiente y económicamente más rentable. Nuestra investigación se ha desarrollado en áreas del valle interandino en el centro de Colombia (departamento del Tolima) en el bosque seco tropical. Esta investigación tiene como propósito, constituirse en una herramienta de implementación de cultivo de la vid, viable económica, social y ambientalmente, como medio de subsistencia a familias campesinas, desplazados y desmovilizados en la era del postconflicto colombiano. A su vez, representa una alternativa de reemplazo a los cultivos ilícitos como la coca y la marihuana, que han prosperado en zonas afectadas por la guerra en Colombia.

The results achieved in Republic of Moldova in using the potential of grapevine Gene pool over the past 40 years are significant: new varieties for diverse utilisation, designed for complex biological resistance to stress factors, for reduced pressing on the environment and for excellent capabilities for ecological agriculture. Breeding programs resulted in modernization of assortment – were created more than 80 new varieties for table and wine grapes, most of them with advanced biological resistance, and 32 varieties were included in actual assortment and other are in the process of testing. An important feature of this assortment is presence of seedless varieties, well adapted to our geographical area. According to their characteristics (resistance, quality, productivity), created seedless varieties are not only a pioneering for the assortment of the Republic of Moldova, but for the entire Euro-Asian region. New seedless varieties and perspective elites manifest an increased percentage of buds started in vegetation after the wintering. High fertility, medium to large and very large grapes, accumulation of sugars and total acidity in must favourably for consumption of fresh grapes or for technological processing, suitability for long-term storage and transportability for some of them, denote their high productive and qualitative potential.

The negative effects of plant protection products on the human health and the environment have become a major concern for consumers and politics in Europe. In the last years new policies for risk mitigation and reduction of use of synthetic pesticides has been enforce in Europe and Switzerland. A possible strategy to reduce the use of plant protection products is to spray according to the epidemic of diseases and pests by following decision support systems (DSS). The platform VitiMeteo offers a wide set of forecasting models for viticulture including downy and powdery mildew, black rot, grape berry moth and rust mite. Two research institutes the Staatliches Weinbauinstitut Freiburg (Germany) and Agroscope (Switzerland) developed VitiMeteo jointly. A consortium was built with the company Geosens (Germany) which is in charge of the programming of the different forecasting software. Each institute is running his own internet website with specific tools and feature for each country but the core of the system is the same. The combination of these different DSS allows a significant reduction of plant protection products used. All these forecasting systems and tools are freely available for the winegrowers on the platform www.vitimeteo.de and www.agrometeo.ch. The use of these platforms helps the winegrowers to meet current society's expectations.
Effect of certain treatments to prevent or partially reverse the pinking phenomenon in susceptible white wines
Authors: Cojocaru G.A. , Antoce A.O.
Published: October 2019

Pinking is a phenomenon occurring in certain white wines produced under highly reductive conditions which occasionally develop a pink colouration when suddenly exposed to air. The pink colouration gives the impression of wine being stained with red grape pigments, but in fact the phenomenon is a transformation in the presence of oxygen of some specific phenolic compounds found in the susceptible varieties. In our experiments two white wines based on Sauvignon blanc and Chardonnay, respectively, were found to have a high potential toward pinking. This study evaluates the potential of certain treatments to prevent the development of pinking or to partially reverse it after occurrence. Treatments tested involved the addition of 20 to 40 mg/l ascorbic acid or 5 to 30 mg/l of catechinic tannin prior to bottling. Both types of treatments had the potential to prevent pinking, irrespective of dosage used, as long as a normal concentration of free SO2(above 0.8 mg/l molecular SO2) was maintained in the wines. Other treatments tested for bottled wines already developing a pink shade were the exposure of the bottle to UV light or the keeping in complete darkness, respectively. In the absence of any other pinking preventive measure both treatments proved to have a certain effect upon reversing the phenomenon. The UV light treatment shows more potential to reverse pinking than darkness and it may work even better on bottles with lower UV light filtering power (in this experiment Antique green glass bottles, with 70–80% UV reduction effect, were used). Differences among the responses of varieties are also present, with Chardonnay being less responsive to antioxidants than Sauvignon blanc. The parameters determined for the evaluation of pinking level are: Pinking potential index (PPI), proanthocyanidins (PAC), co-pigmented anthocyanins (Cp), polymeric pigmented anthocyanins (P) and total pigments (TP), as well as the absorbtion at 420 nm (for browning), 500 and 520 nm (for pinking), 620 nm (for blue shades).

In early 1990's European Union has established new isotopic approach for detection of wine authenticity. In this article we setup the possibility of using new approach using new EIM – Module – IRMS (Ethanol Isotope Measurement – Module – Isotope Ratio Mass Spectrometry) instrumental technique and new analytical parameter δDn(δ2Hn) wine ethanol value, which represents δ2H value of non-exchangeable hydrogen stable isotope ratio in ethanol, with other isotopic species (δ18O values in wine water) to improve detection of illegal wine production practices such as addition of sugar and/or dilution with water. Total of 42 wine samples were analyzed. 10 wine samples (out of 42) were prepared from grapes by alcoholic fermentation and analyzed for δDn values of ethanol. 19 wine samples (out of 42) were collected from wine producers in Serbia plus 1 wine samples designated from United States was taken from Serbian market and analyzed for δDn values of ethanol, δ18O values in wine water and also δ13C values in wine ethanol. Furthermore 9 wine samples (out of 42) were taken from Hungarian market and analyzed for δDn values of ethanol, and also 3 wine samples (out of 42) were taken from Austrian market and analyzed for δDn values of ethanol. All experiments were done in 4 isotope laboratories located in US, Austria, Hungary and People's Republic of China. δDn values of ethanol were measured by using EIM Module connected to FlashHT 2000 pyrolizer (one laboratory – Imprint Analytics GmbH, Austria), while in other 3 laboratories (US – COIL – Cornell University, Stable Isotope Laboratory, Hungary – Isotoptech Ltd, Debrecen, Hungary and China – C.N.R.I.F.F.I. – China National Institute of Food and Fermentation Industries Limited) EIM Module was connected to TC/EA (High Temperature Conversion Elemental Analyzer). Peripherals in all laboratories were further interfaced with isotope ratio mass spectrometer. Furthermore δ18O values in wine water were measured by using Gas Bench II interfaced also with isotope ratio mass spectrometer (one laboratory – US). Obtained results from all 4 laboratories have shown that this new approach which uses δDn in wine ethanol is more effective in improving detection of illegal wine production practices (sugar enrichment and water dilution) and origin of ethanol, and also detecting the addition of corn or beet sugar, sugar syrup to wine, or dilution of grape must with water prior to alcoholic fermentation.

Cork powder as a new natural and sustainable fining agent to reduce negative volatile phenols in red wine
Authors: Filipe-Ribeiro L. , Cosme F. , Nunes F.M.
Published: October 2019

In red winemaking, especially those aged in wood barrels, the contamination and growth ofDekkera/Brettanomycesyeasts results in the formation of 4-ethylphenol (4-EP) and 4-ethylguaiacol (4-EG). These volatile phenols (VPs) are responsible for negative aromatic notes like horsy, barnyard, smoky and medicine, decreasing significantly red quality and its commercial value. In this work, cork powder waste was especially prepared and used to remove these negative volatile phenols (4-EP and 4-EG) from spiked red wine. The optimisation of cork powder performance by removal of dichloromethane and ethanol cork extractives, air removal and ethanol impregnation, allowed to obtain 41 to 62% of 4-ethylphenol and 50 to 53% of 4-ethylguaiacol removal from VPs spiked red wine applied at 250 g/hL. There was no significant impact on phenolic acids and monomeric anthocyanins, although being observed a decrease in the headspace aroma abundance (40%). This optimised cork powder allowed to decrease significantly the wine negative phenolic character, bitterness and astringency, recovering the positive fruity and floral sensory attributes. Results show that optimised cork powder can be a good solution for VPs removal, presenting a great potential to be a new oenological fining agent, contributing to the wine industry sustainability.

This study aims to understand the convergences and divergences between the social representations associated with the different terms used to designate sparkling wine in Brazil and in France. For this purpose, we carried a verbal association task to collect the social representation content in Brazil and France. It was word inductor in Brazil: sparkling wine, sparkling wine moscatel, cider, and Champagne. In France, sparkling wine, pétillant wine, crémant wine, and Champagne. There are common terms used to designate sparkling wine that still confuses consumers. The data was analyzed by ascending hierarchical cluster analysis and presented by a dendrogram. This method evidences the dissimilarity between inductors. The results present on a major cluster with all sparkling wines and another with the Brazilian inductor cider. After, we have also the Brazilian inductor moscatel separated, and show a close similarity between French inductors, Champagne and sparkling wine. Even with it being an exploratory research, the results show start to explain the convergences in the French context, due probably to the long history of these products. On the other side, in Brazil, the divergence, principally with cider and moscatel, that are recent in the Brazilian market, compared to sparkling wine and Champagne.
