This study aimed to evaluate the usefulness of bioactive extracts obtained from red wine by-products, such as grape skins and stems, for reducing or eliminating the use of SO2 in red wine production. Special attention was focused on guaranteeing the microbiological stability of the red wines and protecting them against oxidation. Therefore, the antioxidant and antimicrobial activities of the extracts and red wines were studied. Red grape stems and skins, by-products of the wine industry, from six types of monovarietal wines, were used. Extracts obtained from stems displayed higher concentrations of total phenolic compounds and higher in vitro antioxidant activity. Both stem and skin extracts demonstrated higher antimicrobial activity against pathogenic bacteria and lower activity against yeasts. In the wines produced, higher antimicrobial and antioxidant activities were observed, mainly in the skin extract batches. This study highlights that bioactive extracts obtained from by-products of wine making could be used to reduce or eliminate the use of SO2 in wine production. In this way, healthier red wines could be obtained while guaranteeing their microbiological stability and protecting them from oxidation. Furthermore, the use of these by-products is strongly associated with the circular economy, as they could help to reduce the environmental impact of the wine industry.

Unripe grapes (UGs) are a waste product of vine cultivation rich in natural antioxidants. These antioxidants could be used in winemaking as alternatives to SO2. Three extracts were obtained by maceration from Viognier, Merlot and Sangiovese UGs. The composition and antioxidant activity of the UG extracts were studied in model solutions at different pH levels. The capacity of the UG extracts to protect wine colour was evaluated in accelerated oxidation tests and small-scale trials on both red and white wines during ageing in comparison with sulphur dioxide, ascorbic acid and commercial tannins. The Viognier and Merlot extracts were rich in phenolic acids while the Sangiovese extract was rich in flavonoids. The antioxidant activity of the extracts and commercial tannins was influenced by the pH. In the oxidation tests, the extracts and commercial products showed different wine colour protection capacities in function of the type of wine. During ageing, the white wine with the added Viognier UG extract showed the lowest level of colour oxidation. The colour of the red wine with the UG extract evolved similarly to wine with SO2 and commercial tannins. The obtained results indicated that natural and healthy UG extracts could be an interesting substitute for SO2 during wine ageing.

SO2 is a very important wine preservative. However, there are several drawbacks associated with the use of SO2 in wine. The aim of this work is to evaluate the effect of the partial substitution of SO2 in the Tempranillo wine by a Mazuelo grape stem extract and by a commercial vine wood extract (Vinetan®). The results were compared with a control sample (with no addition of any extract). After 12 months of storage in a bottle, total anthocyanin content, together with total polyphenol and flavonoid content were slightly higher for control wines than for those treated with extracts. These differences were of little relevance, as no differences in antioxidant activity were found between any of the wines at the end of the study. The sensory analysis revealed that the use of both extracts as partial substitutes of SO2 could lead to wines with good organoleptic properties, similar or even better to the control ones.

Inflammation, thrombosis and oxidative stress are rarely studied together when wine’s biological activity is concerned; hence the existing literature lacks a holistic point of view in the biological outcome. The scope of the present study is to parallel evaluate the effect of wine extracts on those mechanisms. Ten wine varieties and two different extraction methods were used leading to five extracts for each wine: total lipids (TL) and fractions with different phenolic compound classes (FI, FII, FIII and FIV). Their effect on oxidative stress, platelet aggregation and the secretion of cytokines from mononuclear cells was measured and a biological score was calculated. FII of white wines is the most potent extract and the extracts FIII and TL are following. Specifically, FII had higher anti-oxidant and anti-inflammatory score while all three fractions had a similar anti-platelet score. Furthermore, FII and FIII extracts were the most potent red wine extracts and revealed the highest anti-oxidant and anti-inflammatory scores. White wine FII extracts were more potent than the red wine ones while FI and FIV extracts of red wine were more potent than the white wine ones. In conclusion, the protective effect of a wine is independent of its color but is strongly associated with its microconstituents profile. FII extract revealed the highest biological score and further examination is needed in order to identify the compounds that are responsible for the aforementioned actions.

An extract from red-wine grape fermentation, ANOX® has been developed as a source of red-wine polyphenols, which are thought to inhibit several of the pathogenic pathways that lead to cardiovascular disease. New data indicate that this extract has a significantly greater effect than either red wine or red-wine powder on the inhibition of platelet aggregation in vitro. Based on this data, about 300–500 mg of the extract is equivalent to the daily dose of red-wine polyphenols that appears to protect against cardiovascular disease. The possible synergistic effect of red-wine polyphenols with vitamin C, their vasorelaxing activity and their possible role in preventing over-crosslinking of connective tissues (premature ageing) are considered. The extract contains standardized amounts of the whole spectrum of polyphenolic compounds found in red wine and may provide a valuable reference substance in clinical investigations of the physiological actions of plant polyphenols; its potential use in functional nutrition and preventive medicine is also discussed.

A reduction in the risk of coronary heart disease has been associated to moderate red wine consumption. We tested whether a nonalcoholic red wine extract would open mitochondrial KATP channels in guinea pig myocytes. The opening of mitochondrial KATP channels was assessed by endogenous flavoprotein fluorescence. Red wine extract (100 μg·mL–1) increased flavoprotein oxidation (10.9% ± 1.2%, n = 20). This effect was prevented by the mitochondrial KATP channel blocker, 5-hydroxydecanoate (500 µmol·L–1; 0.3% ± 1.1%, n = 13), confirming the hypothesis that red wine extract opens mitochondrial KATP channels.

Several epidemiological studies demonstrate that moderate (red) wine consumption may afford protection against cardiovascular diseases. Protection is ascribed to the biological activity of wine components, many of which, however, are discarded during winemaking. In vitro rat thoracic aorta rings contracted with phenylephrine or KCl were used to assess the vasorelaxant activity of extracts from wine pomaces (seeds and skins) of the Calabrian autochthonous grape variety Magliocco dolce (Arvino). NMR spectroscopy was used to ascertain their chemical composition. Data demonstrate that seed and skin, but not must, extracts are capable of relaxing vascular preparations in an endothelium-dependent manner, similarly to the red wine extract, due to the presence of comparable amounts of bioactive constituents. In rings pre-contracted with 20–30 mM KCl, only seed extracts showed a moderate relaxation. The most efficacious vasodilating extract (wine) showed a good antioxidant profile in both [(2,2-diphenyl-1-picrylhydrazyl)acid] radical (DPPH) and [2,2’-azino-bis (3-ethylbenzothiazoline-6-sulphonic acid)] radical (ABTS) assays. In conclusion, winemaking from Magliocco dolce grape can provide potentially health-promoting by-products useful in cardiovascular disease management.

The benefits associated with the consumption of red wine due to its rich pool of phenolic compounds are well-recognized, thanks to the antioxidant activity related to these kinds of molecules. However, wine drinking should be done in moderation, or is forbidden for some populations for ethnic or religious reasons. One way to still enjoy the advantages of red wine is to use its dry extract. In order to test the ability of the red wine dry extract to reveal its antioxidant activity, it was solubilized in water to produce water-in-oil (W/O) emulsions based on olive oil. After the selection of the right emulsion composition, kinetics of oil oxidation were carried out in oil and emulsions in the presence of an increasing amount of red wine extract, whose presence influenced the rate of oxidation by slowing it down. This behavior was confirmed by monitoring the oxidation reaction in two ways; i.e., with the classical method that consists of the determination of the peroxide value, and with an accelerated test making use of 2,2′-azobis(2,4-dimethylvaleronitrile) (AMVN) and diphenyl1-pyrenylphosphine (DPPP). The first is a molecule that triggers the reaction at 40 °C, and the other is a molecule that by reacting with hydroperoxides becomes fluorescent (DPPP=O). Moreover, by comparing the emulsion structures observed by optical microscopy, no differences in the size of the dispersed aqueous phase were detected with the increase of the wine dry extract, which is an aspect that confirmed that the antioxidant activity was directly proportional to the wine extract concentration, and thus to the phenolic content.

La dégénérescence maculaire liée à l'âge (DMLA) constitue la première cause de handicap visuel dans les pays industrialisés. Bien que les traitements actuels se focalisent sur les stades avancés de la maladie, des études récentes mettent en évidence l'importance des traitements préventifs et d’une alimentation riche en antioxydants pour prévenir l’apparition de la maladie. Cette thèse a pour objectif d'évaluer les propriétés antioxydantes, anti-inflammatoires et anti-angiogéniques d'un cocktail polyphénolique, à savoir un extrait sec de vin rouge (RWE) ainsi qu’une d’un polyphénol seul, le resvératrol (RSV). Les résultats de cette étude ont démontré que le RWE prévenait la sécrétion et la voie de signalisation du facteur de croissance endothéliale VEGF-A, impliqué dans la néoangiogenèse caractéristique de la forme la plus sévère de la DMLA. De plus, cette thèse a mis en évidence les effets protecteurs du RWE sur les événements précoces et initiateurs de la maladie. En effet, le cratère anti-oxydant du RWE permet non seulement de diminuer le stress oxydant, mais aussi de prévenir leurs dommages dans les cellules rétiniennes. Par ailleurs, le RWE a montré un fort pouvoir anti-inflammatoire dans les cellules rétiniennes, et aussi dans les cellules immunitaires. Enfin, les résultats de cette étude ont permis de montrer que les caractères pléiotropique du RWE sont supérieurs à ceux du RSV seul. Ces résultats prometteurs soulignent l’intérêt des polyphénols dans la lutte contre la DMLAAge-related macular degeneration (AMD) is the leading cause of visual impairment in industrialized countries. Ours days, treatments target advanced stages of the disease. However, recent studies highlight the importance of preventive treatments and an antioxidant-rich diet in order to prevent the disease. The aim of this thesis was to evaluate the anti-oxidant, anti-inflammatory and anti-angiogenic properties of a polyphenolic cocktail, a red wine dry extract (RWE) and a polyphenol, resveratrol (RSV). The results of this study demonstrated that RWE prevented the secretion and the signaling pathway of the endothelial growth factor VEGF-A, involved in the neoangiogenesis characteristic of the most severe form of AMD. In addition, this thesis highlighted the protective effects of RWE on early, disease-initiating events. RWE's anti-oxidant properties not only reduces oxidative stress, but also prevents their damage on retinal cells. In addition, RWE showed strong anti-inflammatory properties in retinal cells, as well as in immune cells. Finally, the results of this study showed that the properties of RWE were superior to those of RSV alone. These promising results underline the value of polyphenols cocktails in the fight against AMD

The study was focus on the antioxidant effect and free radicals scavenging activity of red wine extract of onion (RO). Results showed that both red wine (RW) and RO had the similar abilities of antioxidation and scavenging activity on free radicals, but RO showed much better chelating activity on ferrous ion than RW. To further evaluate the effect of RO on the prevention of cardiovascular diseases. A randomized and placebo-controlled study was designed. Ten subjects were included in RO group and eleven subjects were in RW group, and 250ml RO or RW were respectively supplied for each subject every day. After ten weeks of intervention, both groups showed were greatly decreased serum low-density lipoprotein cholesterol (LDL-C), increased plasma total antioxidant capacity, and longer lag-time of LDL oxidation. Decreased serum total cholesterol and increased plasma glutathione were only found in RO group. In addition, the activity of coagulation factor VII was greatly reduced by RO. In conclusion, moderate intake of RO probably improved better health benefits than RW.

Flavonoids and polyphenols, their great abundance in our diet especially in vegetables, fruits, herbs, leaves, seeds, red wine, tea, coffee, beer, and several medicinal plants, and their probable role in the prevention of various diseases associated with oxidative stress, such as cancer and cardiovascular and neurodegenerative diseases is emerging. Among, resveratrol, quercetin, and rutin have received more medical attention. Accordingly, these compounds are thought to have antiplatelet, antithrombosis, vessel protector, and antioxidant properties, protecting the body against the kind of damage linked to increased risk for conditions such as cancer and heart disease. Garlic (Allium sativum L.) has been used for culinary and medicinal purposes by many countries. Garlic is a particularly rich source of physiological compounds, which are thought to be responsible for its flavor and aroma, as well as its potential health benefits. In this study, three marker ingredients namely, resveratrol, quercetin, and rutin levels in garlic red wine extracts (RWG) were quantitated by HPLC. The results showed that the concentrations of these compounds were decreased with extraction time. The highest resveratrol level (1.52 mg/L) was observed at beginning of extraction (day 0) for RW5G1 (the ratio of red wine to garlic = 5:1, v/w), yet slightly better than red wine (RW) alone (1.43 mg/L). Quercetin also reached the highest level (5.53 mg/L) for RW7G1 which value is similar to the RW (5.42 mg/L). The best rutin content (76.90 mg/L) was found in the case of RW7G1 and no significant difference was found for RW at day 0. Parallely, the W1G1 (the ratio of water to garlic = 1:1, v/w) exhibited the highest resveratrol level (0.27 mg/L) at day 3 and the best rutin level of 0.55 mg/L was found at day 1. Quercetin level have becomes of negligible value while using water extract. In summary, both garlic and RW contain three marker ingredients, it is possible that a synergistic effect would be seen in an appropriate extraction ratio. Thus, will providing a healthier for cardiovascular protective effects.

Medical research indicates that intake of vegetables red wine, fruits, and relative foods rich in polyphenols, can reduce the incidence of cancer and cardiovascular disease. The onion genus Allium such as garlic, can inhibited the oxidation of LDL are receiving considerable attention for their role in prevention of coronary heart disease; polyphenols and proanthocyanidin are good antioxidants in red wine that significantly diminished the risk factors of atheorosclerosis. In this study, the garlic were extract with red wine in different ratio, and time to determined the antioxidant activity of red wine garlic extracts (RWG) in terms of total phenol contents (expressed as gallic acid equivalents, GAE), reducing power, and DPPH free radical scavenging assay. The results indicated that the best antioxidant activity was found for RW5G1 (red wine:garlic = 5:1) at day 7 after extraction. The total phenol contents for RW5G1 and RW (red wine) were 1891.0026.73 and 163040 mg GAE/L, respectively. The best reducing power was found to be 24.530.35 mg Vit-C/L for RW5G1, which is higher than that of RW (21.791.09 mg Vit-C/L). Similarly, the DPPH scavenging activity for RW5G1 (95.70.89%) was still better than RW (92.30.48%). The best antioxidant activity was obtained for W1G1 among the water extracts, but still less than RWG and RW. The temperature was also affects the extract efficiency. The antioxidant activities were also conducted at 4C, room temperature, and 40C. The highest antioxidant activity was observed at 4C for RW5G1. The general decomposition of variation for the integrated analysis of measurement data sets from this study suggests that the higher in total phenol contents, the better reducing power was observed. The best performance in total phenol contents, reducing power, and DPPH scavenging activity was founded for RW5G with the worst for RW1G1. Yet, three indicators for antioxidant activity somehow showed a positive correlation. In conclusion, the garlic may play a synergistic effect with relation to antioxidant activity as compared to the RW alone. Obviously, the garlic exhibited a potential on the prevention of coronary heart disease as well as atherosclerosis formation.

Oxidation of low density lipoproteins (LDL) is a crucial step in the pathogenesis of atherosclerosis. Dietary antioxidants that can inhibited the oxidation of LDL are receiving considerable attention for their role in prevention of coronary heart disease. Onion and red wine contains the abundant natural materials (e.g. polyphenols or flavonoids) which are bearing a premium antioxidant activity. In this study, the effects assessments of red wine combine with the onions, both are able to restraint the cardiovascular disease originally, on the preventing the LDL oxidation and atherosclerosis were engaged both in vitro and in vivo. The results indicated that the red wine (RW) and red wine extract of onion (RWOs) scavenging over 90% of free DPPH radical. No significant scavenging activity was found from hydroxyl radical scavenging activity test, the reducing power on metallic compound formation, and antioxidant activity (all carried out with 0.5 mg/mL DMC) as well as inhibitory on LDL oxidation (REM of 1.0) while using other extraction solvents. The reducing power for low dose RWOs was found to be 1.04 mg/mL Vit-C equivalent. Furthermore, the RWOs also inhibited copper-induced LDL oxidation in a micromolar level of flavonoids (antioxidants ubiquitous in onion and red wine). Total phenolic compounds in RW and RWOs were 1.90 and 1.54 mg/mL gallic acid equivalents (GAE) respectively; these values are higher than other solvent extracts, the antioxidant activity of red wine extracts was notably as a result of inhibiting the copper mediated oxidation of LDL. The CE results also revealed that the RWOs had higher activated components (i.e. quercetin, rutin and resveratrol, found to be 18.21, 5.15 and 4.25 mg/L) than RW and WOs. In vivo results showed that feeding the low dose RWOs (2 mL/kg) into Golden Syrian hamster supplemented with the cholesterol-enriched diet (2% of cholesterol was added) had significantly diminished the level of total cholesterol (TC), triglyceride (TG), and LDL in plasma by 65.0, 86.1, and 68.5% respectively after 16 weeks. Considerable decreased in lipids accumulation on liver and abdominal aorta was found in ROWs treatment animal as examed by tissue biopsy. Furthermore, the low dose RWOs had better performance than RW and high dose RWOs (5 mL/kg) on liver cellular swelling improvement and fatty liver retardation. In conclusion, the low dose RWOS had excellent feat for antioxidant activity, inhibition of LDL oxidation, lowering the plasma TC, TG, and LDL level of hypercholesterol animal as result from both in vitro and in vivo experimentations. Obviously, the onion plays a synergetic effect on the prevention of coronary heart disease as well as atherosclerosis formation

It will include extracts from Celtic literature and classical literature relating to the Celts. The Celtic world covered Western Europe from Ireland to the southern Mediterranean and extending into Galatia (Asia Minor) during the Iron Age and the Roman Empire (between 600 BC and 200 AD). Drawing from a wide variety of sources, including the latest archaeological evidence, and Celtic and classical literature, this publication provides an accessible and up-to-date account of daily life in this Celtic world. With her extensive background in ancient history, Joan Alcock vividly brings to life the civilisation of the Celts, a world with complexities and nuanced variations like any of the other great ancient civilizations. The book details the structure of the Celtic world, its constituent territories and cultures and the interrelationships of these tribes and lands, the roles within each society, including warriors, farmers, craftsmen (who still influence fashions today), slaves, women and children. Detail is given of religion and superstition, feasts and festivals, burial practices, building types and materials, domestic life, family customs, marriage, the raising of children and more. The final chapter examines the decline of the Celts, and the survival and re-emergence of Celtic cultural traditions in the modern era.

All books in this flagship series contain carefully selected substantial extracts from key cases, legislation, and academic debate, providing able students with a stand-alone resource. Drawing on extensive experience, the authors offer a detailed and authoritative exposition of family law illustrated by materials carefully selected from a wide range of sources. The book’s principal aims are to provide readers with a thorough understanding of family law, in a way that stimulates critical reflection. Readers are encouraged to consider how and why the law has developed as it has, what policies it is seeking to pursue, whether it achieves the right balance between the rights and interests of individual family members and the wider public interest, and how it operates in practice. This edition provides updates and revised discussion on: civil partnership after R (Steinfeld and Keidan) (2018); divorce law following Owens v Owens (2018) and the government’s consultation on reform; domestic abuse, including consultation ahead of the draft Domestic Abuse Bill and forced marriage; rights under the ECHR and UNCRC in children proceedings; surrogacy following Re Z (A Child) (No 2) (2016); child arrangements orders; specific issue and prohibited steps orders, including relocation law; local authority voluntary accommodation following Williams v London Borough of Hackney (2018). There is a new chapter dedicated to property and financial issues after the breakdown of relationships other than marriage and civil partnership. The introductory chapter, supported by materials on the Online Resources, considers some of the contemporary challenges faced by the family justice system.

AbstractIn classical computers, information is represented as the binary digits 0 or 1. These are called bits. For example, the number 1 in an 8-bit binary representation is written as 00000001. The number 2 is represented as 00000010. We place extra zeros in front to write every number with 8-bits total, which is called one byte. In fact, every classical computer translates these bits into the human readable information on your electronic device. The document you read or video you watch is encoded in the computer binary language in terms of these 1’s and 0’s. Computer hardware understands the 1-bit as an electrical current flowing through a wire (in a transistor) while the 0-bit is the absence of an electrical current in a wire. These electrical signals can be thought of as “on” (the 1-bit) or “off” (the 0-bit). Your computer then decodes the classical 1 or 0 bits into words or videos, etc.

The use of natural ingredients with active functions has been intensively studied in the last years, as a consequence to consumer preferences for organic products. Application of circular economy principles determined a significant research activity in the viticulture field. The use or re-use of vines parts for so-called nutraceuticals or other consumer-goods applications, are basically centered on their phytochemical and microbiological characterization. Eurostat updates ranks Romania fifth among the EU member states, with a total area under vines of 183,717 hectares. Characterization of four Vitis vinifera L. varieties, out of which one pure Romanian variety (Feteasca Neagra), cultivated in organic and conventional vineyards, together with pedoclimatic conditions have been provided. Data on phytochemical parameters and antimicrobial activity of extracts obtained from different anatomic parts of grapes were included. Analytical protocols and techniques applied were presented, together with data and results interpretation. Several chemometric algorithms have been used as complementary tools for interpretation of the instrumental analytical data.

Abstract Based on his first few voyages, Christopher Columbus concluded that the weather in the New World is benign: “In all the Indies, I have always found May-like weather,” he commented. Although sailing through hurricane-prone waters during the most dangerous summer months, he did not have any serious hurricane encounters during his first three voyages. (But in June 1495, on his second voyage, three of his four ships were sunk in Isabela Harbor, on the south side of Hispaniola, by what seems to have been a waterspout.) During these voyages, Columbus heard from native inhabitants about horrible tempests they called “Huracán,” the word for their god of evil (Chapter 3), and he probably learned from them the portents to look for. By the time of his fourth voyage to the New World, in 1502, Columbus had had a serious falling-out with the bureaucrats appointed by Spain to govern the fledgling colonies and to extract gold and other commodities from the native inhabitants. Among the more unfriendly of these exploiters was Don Nicolas de Orvando, the governor of Hispaniola, with whom Columbus had been forbidden contact by his Spanish sovereigns. But as Columbus entered the outer roadstead of Santa Domingo, he recognized the ominous signs of an approaching violent storm: an oily swell emanating from the southeast and a developing veil of cirrostratus overhead. Concerned for the safety of his men and ships, he sent a message to Governor Orvando begging to be allowed to seek refuge in Santa Domingo harbor. Columbus had observed that the governor was preparing a large fleet of some 30 boats to set sail for Spain, carrying large quantities of gold and slaves, and warned him to postpone the trip and to take measures to secure the ships. Refusing both the request and the advice, Orvando read Columbus’s note aloud to his minions, who roared with laughter at the forecast by the amateur meteorologist from Genoa.

Повний текст джерелаАнотація:
The Mediterranean Diet (MedDiet) is a nutritional pattern native to many cultures within the Mediterranean Basin. The diet is composed of fruits, vegetables, fish, eggs, fermented dairy, grains, poultry, and minimal consumption of red meats such as lamb and beef. The diet encourages the consumption of extra virgin olive oil and moderate red wine for those who consume alcohol. The diet does not incorporate processed foods and sugary beverages. The MedDiet is rich in many micronutrients and has a healthful fatty acid profile (primarily mono- and polyunsaturated fats, with low amounts of saturated fats). The diet is rich in foods with high magnesium content, such as leafy green vegetables, nuts, seeds, and some lesser magnesium-rich foods (e.g., fish). The MedDiet is associated with reduced incidence of several diseases such as cardiovascular disease, cerebrovascular disease, neurodegenerative disease, metabolic syndrome, and type 2 diabetes mellitus. Magnesium intake has been shown to play a prominent role in the prevention and management of many of these diseases, with some of the disease-preventing capacity of the MedDiet likely caused by its high magnesium content. Those making nutritional recommendations in line with the concepts of MedDiet should particularly encourage the consumption of foods high in magnesium.

This chapter will explore the range of periodical publications that have engaged with politics on a regional or national level without an overemphasis on the workings of the Westminster parliament. These might be serving geographically distinct communities or they may be circulating among politically disaffected with radical aims. Some periodicals have taken advocacy journalism to petition for causes and movements outside the normal mechanics of the Westminster cycle such as the publications fighting for women’s rights from Votes for Women in 1907 to Spare Rib from 1972. Specific campaigns and causes have been facilitated through such as the pacifist Peace News in 1936 and the New Internationalist which started to encourage greater awareness of overseas development issues in 1973. Other peridocials have addressed a particular political community, for example the Socialist Labour Press out of the Red Clydeside era, the left-wing Irish Republican, An Phoblacht from 1906 and other constituencies have more recently drawn upon publications such as Living Marxism, Schnews, Class War.

Повний текст джерелаАнотація:
The Mediterranean diet (Med-diet) includes a high consumption of cereals, fruits, legumes and vegetables, a moderate fish intake and a low consumption of red meat. Olive oil is a basic component of the Med-diet due to its numerous health benefits. In the last decade, many epidemiological studies have confirmed the protective role of extra virgin olive oil (EVOO) against several chronic illnesses including cardiovascular diseases. EVOO is mainly composed of triacylglycerols, with oleic acid as the dominating esterified fatty acid, and other minor compounds. Among them, phenolic compounds, such as hydroxytyrosol and its derivatives (oleuropein and tyrosol), are the principal components responsible for the cardioprotective effects. They are endowed with wide biological activities, including strong antioxidant properties, allowing the prevention of cardiovascular risk factors, such as atherosclerosis, plasma lipid disorders, endothelial dysfunction, hypertension, obesity and type 2 diabetes. The aim of the present chapter was to elucidate the beneficial effect of EVOO, as part of the Mediterranean-style diets, on cardiovascular risk factors and to discuss the underlying mechanisms by which polyphenols exert their effects.

Annette Gordon-Reed and Peter S. Onuf discuss Lewis’s presentation of Jefferson’s family life, specifically the ways in which he sought to orchestrate the relationship between himself and both his legal family and his extra-legal family. Widowered at thirty-nine, Jefferson exercised an outsized influence on the daughters he had with his wife, Martha Wayles Jefferson. He also directed the lives of his children with Sally Hemings, an enslaved woman, by maneuvering them out of slavery. Although Jefferson often wrote of a sharp distinction between public and private life, he saw the family as a prototype for society as a whole, with the hope that bonds of affection could bind citizens to one another.

Facial expression recognition is a challenging task. A facial expression is formed by contracting or relaxing different facial muscles on human face that results in temporally deformed facial features like wide-open mouth, raising eyebrows or etc. The challenges of such system have to address with some issues. For instances, lighting condition is a very difficult problem to constraint and regulate. On the other hand, real-time processing is also a challenging problem since there are so many facial features to be extracted and processed and sometimes, conventional classifiers are not even effective in handling those features and produce good classification performance. This chapter discusses the issues on how the advanced feature selection techniques together with good classifiers can play a vital important role of real-time facial expression recognition. Several feature selection methods and classifiers are discussed and their evaluations for real-time facial expression recognition are presented in this chapter. The content of this chapter is a way to open-up a discussion about building a real-time system to read and respond to the emotions of people from facial expressions.

Computer graphics have widely spread out into various computer applications. After the early wire-frame computer generated images of the 1960s, spatial representation of objects improved in the 1970s with Boundary Representation (B-Rep) modeling, Constructive Solid Geometry (CSG) objects, and free-form surfaces. Realistic rendering in the 1990s, taking into account sophisticated dynamic interactions (between objects or between objects and human actors, physical interactions with light, and so on) now make 3Dscenes much better than simple 3D representations of the real world. Indeed, they are a way to conceive products (industrial products, art products, and so on) and to modify them over time, either interactively or by simulation of physical phenomena (Faux & Pratt, 1979; Foley, Van Dam, Feiner, & Hughes, 1990; Kim, Huang, & Kim, 2002). Large amounts of data can be generated from such variety of 3D-models. Because there is a wide range of models corresponding to various areas of applications (metallurgy, chemistry, seismology, architecture, arts and media, and so on) (DIS 3D Databases, 2004; Pittarello & De Faveri, 2006; SketchUp from Google, 2006), data representations vary greatly. Archiving these large amounts of information most often remains a simple storage of representations of 3D-scenes (3D images). To our knowledge, there is no efficient way to manipulate, or archive, extract, and modify scenes together with their components. These components may include geometric objects or primitives that compose scenes (3D-geometry and material aspects), geometrics transformations to compose primitives objects, or observation conditions (cameras, lights, and so on). Difficulties arise less in creating 3D-scenes, rather than in the interactive reuse of these scenes, particularly by database queries, such as via Internet. Managing 3Dscenes (e.g., querying a database of architectural scenes by the content, modifying given parameters on a large scale, or performing statistics) remains difficult. This implies that DBMS should use the data structures of the 3D-scene models. Unfortunately, such data structures are often of different or exclusive standards. Indeed, many “standards” exist in computer graphics. They are often denoted by extensions of data files. Let us mention, as examples, 3dmf (Apple’s Quickdraw 3D), 3ds (Autodesk’s 3DStudio), dxf (AutoDesk’s AutoCAD), flt (Multigen’s ModelGen), iv ( Silicon Graphics’ Inventor ), obj ( Wavefront/Alias ), and so on. Many standardization attempts strive to reduce this multiplicity of various formats. In particular, there is Standard for the Exchange of Product model data (STEP) (Fowler, 1995), an international standard for computer representation and exchange of products data. Its goal is to describe data bound to a product as long as it evolves, independently of any particular computer system. It allows file exchanges, but also provides a basis for implementing and sharing product databases. Merging 3D information and textual information allows the definition of the project’s mock-up. As a matter of fact, 3D information describes CAD objects of the project and textual added information gives semantic information on geometries. The main issues are the sharing and the exchange of the digital mock-up. The next section explains how we use a digital mock-up to create an information system with the help of the semantic included in geometric information. Information is exchanged and shared through a Web Platform.

I do an extra-sensory perception (ESP) experiment on the first day of my statistics classes. I show the students an ordinary coin— sometimes borrowed from a student—and flip the coin ten times. After each flip, I think about the outcome intently while the students try to read my mind. They write their guesses down, and I record the actual flips by circling H or T on a piece of paper that has been designed so that the students cannot tell from the location of my pencil which letter I am circling. Anyone who guesses all ten flips correctly wins a one-pound box of chocolates from a local gourmet chocolate store. If you want to try this at home, guess my ten coin flips in the stats class I taught in the spring of 2017. My brain waves may still be out there somewhere. Write your guesses down, and we’ll see how well you do. After ten flips, I ask the students to raise their hands and I begin revealing my flips. If a student misses, the hand goes down, Anyone with a hand up at the end wins the chocolates. I had a winner once, which is to be expected since more than a thousand students have played this game. I don’t believe in ESP, so the box of chocolates is not the point of this experiment. I offer the chocolates in order to persuade students to take the test seriously. My real intent is to demonstrate that most people, even bright college students, have a misperception about what coin flips and other random events look like. This misperception fuels our mistaken belief that data patterns uncovered by computers must be meaningful. Back in the 1930s, the Zenith Radio Corporation broadcast a series of weekly ESP experiments. A “sender” in the radio studio randomly chose a circle or square, analogous to flipping a fair coin, and visualized the shape, hoping that the image would reach listeners hundreds of miles away. After five random draws, listeners were encouraged to mail in their guesses. These experiments did not support the idea of ESP, but they did provide compelling evidence that people underestimate how frequently patterns appear in random data.

Phenolic compounds, especially phenolic acids, tannins and anthocyanins are among the important biologically active components of wines. Of all the phenolic compounds, anthocyanins are of a particular interest because they have many beneficial effects on human and animal health. In vitro and in vivo studies have revealed the biological potential of these compounds and demonstrated their ability to reduce oxidative stress, to act as antimicrobial substances and to counteract the appearance and progression of many nontransmissible diseases, such as neurodegenerative, cardiovascular, metabolic ones and cancer. In combination with vitamin A and other carotenoids they protect visual function. Anthocyanins and their derivatives have no toxic effect on living organisms, even after ingestion in very high doses. Since the biologically active substances, including anthocyanins, found out in the fermentation medium, are largely absorbed on the surface of the yeast cells, yeast biomass remaining from wine production, can serve as an important source of these substances. The purposes of this research were to obtain anthocyanin extracts from the yeast biomass remaining from the production of the autochthonous wines, to characterize them biochemically, and to assess their antioxidant potential. The research was focused on the sediment yeast biomass from the production of white dry wine Rkatsiteli, red dry wines Merlot and Cabernet, offered by the «Cricova» winery. The extracts were obtained by different methods of destruction of the yeast cell wall, which included the use of the acetic acid and the sodium phosphate buffer solutions, homogenization, different temperatures and biomass-solution ratios. The extracts were characterized by their dry weight, by the content of the anthocyanins, proteins, and carbohydrates, as well as by the activity of the antioxidant enzymes catalase and superoxide dismutase. Depending on the yeast biomass type and the cell wall destruction method the obtained extracts had the dry weight of 2.2 - 13.3 mg/ml, and contained 3.9±0.3 - 20.7±0.4 mg/g of cyanidin anthocyanins, 3.2±0.2 - 9.7±0.4% (d.w.) of proteins, 2.2±0.02 - 31.4±0.3% (d.w.) of carbohydrates, and possessed the antioxidant type catalase activity of 315±2.6 - 524±1.5 mmol/min/mg protein and the superoxide dismutase of 173±5.2 - 457±0.6 U/mg protein. The valuable biochemical composition and high activity of the antioxidant enzymes such as catalase type and superoxide dismutase of the extracts revealed the perspectivity of using the yeast biomass from wine production as a source of anthocyanin preparations for various fields. The results of the research permitted to elaborate a procedure of obtaining the anthocyanin preparations from yeast biomass after red wine fermentation, which is currently being patented.

Investigations on the potential beneficial effect of humic substances on crop plant cultivation under extremely diverse soil and climatic conditions is of global character, thereby knowledge obtained on the basis of local investigations are of great importance world-wide. The aim of the research was to evaluate the effect of different application methods (seed tuber treatment and foliar application) of commercially-produced peat and vermicompost extracts on nutrient uptake in tubers and yield of potato (Solanum tuberosum L.) using field experiments in organic farming system with potato variety ‘Borodjanskij Rozovij’. The tested extracts from the organic products included: peat extract (K45) and vermicompost extract (B45) obtained at +45°C by cavitation. The investigation was carried out at Stende Research Centre (Institute of Agro-resources and Economics) from 2011 to 2012. The chemical composition (N, P, K, Ca, Mg, S, Fe, Mn, Zn, Cu, Mo, B) of potato tubers was determined. The application of organic extract from vermicompost had a stimulating effect on mineral nutrient as N, P, K, Mg, and S accumulation in potato tubers, but 50% of cases showed reduction in Ca and Cu content that could influence the storage of tubers. The use of peat extract was significantly effective when the tubers were treated before planting. On average, tuber treatment and foliar spray with organic extracts contributed to 10% of tuber yield increase.

Maceration is the basic process by which red and white wine production technologies differ from each other, and thanks to this process, red wines acquire most of their characteristics. Mainly during maceration, phenolic compounds, which are powerful antioxidants, are extracted from the solid parts of the berries. Depending on the variety, it is necessary to apply different maceration regimes. The aim of this research was to determine the influence of the maceration temperature and duration on the antioxidant properties of red wines of the Vranac and Merlot varieties. The research was carried out in 2021, where maceration procedures were applied for 6 and 12 days, at temperatures of 16 and 25°C. When macerated for 6 days at 25°C, the wines of both varieties had the lowest total phenolic content (Vranac 7.27 g/l; Merlot 7.15 g/l), but the highest total free anthocyanin content (Vranac 841.04 mg/l; Merlot 572.85 mg/l). Higher antioxidant activity of Vranac variety wines was obtained at shorter maceration (6 days), and Merlot variety wines at longer maceration (12 days).

A designed and constructed wire scanner is used to measure the 30 MeV Cyclotron proton beam profiles in both x- and y-directions prior to injection to another accelerator for Proton Therapy purposes. The position control and control of movement of the two orthogonal wire scanners are done through an interface board to the PC that communicates with both the photo-couple sensors and the designed driver board, mounted and connected to the step motor set up, respectively. The Win AGILE beam transport code is used to measure the beam profiles 407cm upstream from the wire scanner. The beam sigma’s are evaluated to be σx = 2.234 cm2 and σy = 1.850 cm2. The beam emittance in both x- and y-directions obtained are εx = 1.67×10−5 m-rad and εy = 5.64×10−5 m-rad, respectively. The extract Twiss parameters are calculated as αx = −1.28, βx = 12.7, γx = 0.21, αy = −0.55, βy = 3.28, and γy = 0.10.

Abstract Mooring Integrity Management (MIM) is a key operational aspect for FPSO operators, mooring system designers and Recognized Classification Societies (RCS). MIM programs should include the capability to detect a mooring line failure. When direct or indirect measurement of line tension is available continuously and reliably over time, this requirement can be readily fulfilled. Current industry-wide experience shows it has been challenging to develop robust cost-effective real-time anchor line load monitoring systems for the offshore environment. To remedy this situation, Artificial Intelligence (AI) techniques are used to extract an intact or damage diagnosis for a spread moored unit offshore Brazil based on data readily available in situ. The Intelligent Agent (IA) developed has been reviewed by the Classification Society against Ref. [1] and [2]. Following this review a statement of maturity has been issued Ref. [3] qualifying the new technology.

Automatic Language Acquisition focuses on teaching an agent to acquire knowledge to understand the surrounding environment and be adaptive to a new environment. The traditional language understanding models fall into three main categories, supervised, semi-supervised, and unsupervised. A supervised approach is usually accurate but requires a large training dataset, which building process is expensive and time consuming. In addition, the trained model is difficult to shift to other domains. On the other hand, building an unsupervised model is cheap and flexible, but its performance is usually significantly lower than the performance of the supervised one. With a relatively small set of guidance at the beginning, a semi-supervised approach can teach itself through the unlabeled dataset to achieve a comparable performance as a supervised modal. However, building the guidance is not a trivial task since the learning process won’t be effective if the relationship between labeled data and unlabeled data. Different from the traditional modals, when children learn, they do not require large amounts of training data. Instead, they can accurately generalize their knowledge from one object to other objects. In addition, the communication between them and their parents/teachers/peers helps to fix the wrong claims from the generalization. In this paper, we present a multimodal system that simulates the children’s learning process to acquire the knowledge of the entities by studying three types of attributes, descriptive (the outlook of an entity), defining (the components of an entity), and affordance (how an entity can be used). We first utilize an unsupervised Emergent Language (EL) approach to generate symbolic language (EL codes) to interpret the given images of the entities (10 images per entity). The K-Mean clustering methods to group entity images that share the similar EL code. Then we employ a data driven approach to teach the agent the attributes of the entities in the clusters. We first calculate the tf-idf scores of the words from the text pieces (extracted from Corpus of Contemporary American English, a balanced corpus for American English) containing an entity. From the top ranked words with a few sample text pieces, the human expert tells which words are attributes and the attribute type. The human expert also marked the text pieces having the attributes. For example, red is the descriptive attribute of cup in “the red cup’ but not in “a cup of red wine”. The learned knowledge is sent to a bootstrapping modal to find not only new attributes but also new entities. Our system results show that the data driven approach spent much less time but learned more attributes compared with the baseline of our system, teaching the agent the defining attributes of the entities using a carefully designed curriculum.

An experimental survey on a state of the art leading edge cooling scheme was performed to evaluate heat transfer coefficients (HTC) on a large scale test facility simulating an high pressure turbine airfoil leading edge cavity. Test section includes a trapezoidal supply channel with three large racetrack impingement holes. On the internal surface of the leading edge, four big fins are placed in order to confine impingement jets. The coolant flow impacts the leading edge internal surface and it is extracted from the leading edge cavity through 24 showerhead holes and 24 film cooling holes. The aim of the present study is to investigate the combined effects of jet impingement and mass flow extraction on the internal heat transfer of the leading edge. A non uniform mass flow extraction was also imposed to reproduce the effects of pressure side and suction side external pressure. Measurements were performed by means of a transient technique using narrow band Thermo-chromic Liquid Crystals (TLC). Jet Reynolds number and crossflow conditions into the supply channel were varied in order to cover the typical engine conditions of these cooling systems (Rej = 10000–40000). Experiments were compared with a numerical analysis on the same test case in order to better understand flow interaction inside the cavity.

An oscillatory, zero-net-mass flux actuator system, Jet and Vortex Actuator (JaVA), is implemented on the step wall of a backward facing step. JaVA can energize the boundary layer by creating jets or vortices thus it may delay flow separation when used properly. The main part of JaVA is a rectangular cavity with a moving actuator plate. The actuator plate is mounted asymmetrically inside the cavity of the JaVA box, such that there are one narrow and one wide gap between the plate and the box. The main governing parameters are the actuator plate’s width (b), the amplitude (a) and the operating frequency (f). The main target of the control with active jets on the step wall is to influence directly the main recirculation zone, thus as the actuator plate or the step’s vertical wall moves periodically in horizontal direction, a jet emerges into the recirculation zone. Non-dimensional numbers such as the scaled amplitude (Sa = 2πa/b) and the jet Reynolds number (ReJ = 4abf/ν) as well as the cross flow parameter characterize the JaVA-induced flow types and the effects on the recirculation zone. One period consists of one blowing and one suction phase into the recirculation zone. Boundary layer profiles extracted from time-averaged flow fields of the not actuated (f = 0) and actuated cases at various operating frequencies indicate the effect of active flow control. The interaction between JaVA-induced flow regimes and the boundary layer is investigated numerically in an open channel with a BFS. The computational domain consists of a moving zone along the channel and the motion of the actuator plate is generated by a moving grid imposing appropriate boundary conditions with User-Defined-Functions and the calculations are carried out by a commercial finite-volume-based unsteady, laminar, incompressible Navier-Stokes solver. Numerical simulations and comparisons reveal the JaVA-boundary layer interaction for various governing parameters. Reynolds numbers based on the step height for the shallow open channel flow are Reh = 225 and 450. The proposed control method based on suction and blowing with an oscillating vertical step seems to be effective in shortening the recirculation zone length and delaying the flow separation downstream of the backward facing step.

Holographic correction for telescope lens distortions was first proposed and realised yet in 70-es1; in this and more recent experiments2 the holograms were recorded in the static media, providing thus correction only for static distortions. The prospective scheme, which can be used for real-time dynamic correction in wide spectral range, uses thin (plain) dynamic hologram record in the optically addressed liquid crystal spatial light modulators (OA LC SLM). In the experiment we have evaluated wide spectral band imaging by model telescope with the distorted primary lens of the standard test object, irradiated by the tungsten lamp radiation Dynamic hologram was recorded by pulsed radiation at 0.54 μm in OA LC SLM with polymer photoconductor and nematic LC layer. Auxiliary static holographic grating compensated for the dynamic corrector chromatism. In the Figure: (a) - image by non-corrected telescope with distorted by etched glass (extra divergence 6x10-3 rad) primary lens, (b) - corrected image, (c). (d) and (e) - central zone of corrected images, recorded under one and the same experiment conditions by radiation in the band 0.53 ± 0.4 μm - (c), 0.63 ± 0.4 μm - (d, one can see image deterioration due to incomplete compensation at the shifted wavelength) and by white light (e, interim quality between cases c and d).

Several grape varieties and red wines were found to contain large concentration of phenolic compounds which work as antioxidant in-vitro and in-vivo. Wastes from wine production contain antioxidants in large amounts, between 2-6% on dry material basis. Red wines but also white wines were found to prevent lipid peroxidation of turkey muscle tissues stored at 5oC. The antioxidant reaction of flavonoids found in red wines against lipid peroxidation were found to depend on the structure of the molecule. Red wine flavonoids containing an orthodihydroxy structure around the B ring were found highly active against LDL and membrane lipid peroxidation. The antioxidant activity of red wine polyphenols were also found to be dependent on the catalyzer used. In the presence of H2O2-activated myoglobin, the inhibition efficiency was malvidin 3-glucoside>catechin>malvidin>resveratol. However, in the presence of an iron redox cycle catalyzer, the order of effectiveness was resveratol>malvidin 3-glucoside = malvidin>catechin. Differences in protein binding were found to affect antioxidant activity in inhibiting LDL oxidation. A model protein such as BSA, was investigated on the antioxidant activity of phenolic compounds, grape extracts, and red wines in a lecithin-liposome model system. Ferulic acid followed by malvidin and rutin were the most efficient in inhibiting both lipid and protein oxidation. Catechin, a flavonal found in red-wines in relatively high concentration was found to inhibit myoglobin catalyzed linoleate membrane lipid peroxidation at a relatively very low concentration. This effect was studied by the determination of the by-products generated from linoleate during oxidation. The study showed that hydroperoxides are catalytically broken down, not to an alcohol but most probably to a non-radical adduct. The ability of wine-phenolics to reduce iron and from complexes with metals were also demonstrated. Low concentration of wine phenolics were found to inhibit lipoxygenase type II activity. An attempt to understand the bioavailability in humans of antocyanins from red wine showed that two antocyanins from red wine were found unchanged in human urine. Other antocyanins seems to undergo molecular modification. In hypercholesterolemic hamsters, aortic lipid deposition was significantly less in animals fed diets supplemented with either catechin or vitamin E. The rate of LDL accumulation in the carotid arteries was also significantly lower in the catechin and vitamin E animal groups. These results suggested a novel mechanism by which wine phenolics are associated with decreased risk of coronary heart diseases. This study proves in part our hypothesis that the "French Paradox" could be explained by the action of the antioxidant effects of phenolic compounds found at high concentration in red wines. The results of this study argue that it is in the interest of public health to increase the consumption of dietary plant falvonoids. Our results and these from others, show that the consumption of red wine or plant derived polyphenolics can change the antioxidant tone of animal and human plasma and its isolated components towards oxidative reactions. However, we need more research to better understand bioavailability and the mechanism of how polyphenolics affect health and disease.

Resistance to Tomato yellow leaf curl virus (TYLCV) in tomato: molecular mapping and introgression of resistance to Australian genotypes.

Tomato yellow leaf curl virus (TYLCV) is one of the most devastating viruses of cultivated tomatoes. Although first identified in the Mediterranean region, it is now distributed world-wide. Sequence analysis of the virus by the Australian group has shown that the virus is now present in Australia. Despite the importance of the disease and extensive research on the virus, very little is known about the resistance genes (loci) that determine host resistance and susceptibility to the virus. A symptom-less resistant line, TY-172, was developed at the Volcani Center which has shown the highest resistance level among all tested varieties. Preliminary results show that TY-172 is a good candidate to confer resistance to both TYLCV and to Tomato leaf curl virus (ToLCV) in Queensland conditions. Furthermore, Segregation analysis has previously indicated that the resistance is determined by 2-3 genes. In this proposal we aimed to substantiate that TY-172 can contribute to resistance breeding against TYLCV in Queensland, to develop DNA markers to advance such resistance breeding in both Israel and Queensland, and to exploit these markers for resistant breeding in Australian and Israeli lines. To map quantitative trait loci (QTLs) controlling TYLCVresistance in TY172, appropriate segregating populations were analyzed using 69 polymorphic DNA markers spanning the entire tomato genome. Results show that TYLCV resistance in TY172 is controlled by a previously unknown major QTL, originating from the resistant line, and four additional minor QTLs. The major QTL, termed Ty-5, maps to chromosome 4 and accounts for 39.7-to-46.6% of the variation in symptom severity among segregating plants (LOD score: 33-to-35). The minor QTLs, originated either from the resistant or susceptible parents, were mapped to chromosomes 1, 7, 9 and 11, and contributed 12% to the variation in symptom severity in addition to Ty-5. Further analysis of parental lines as well as large F₁, BC₁F₁, F₂ and BC₁F₂ populations originating from crosses carried out, in reciprocal manner, between TY172 and the susceptible processing line M-82 (LA3475) during spring-summer 2010, indicated that: (1) the minor QTLs we have previously identified are in effect not reproducible, (2)Ty-5 alone can yield highly resistant plants with practically no extra-chromosomal effects, and (3) the narrow-sense heritability estimate of resistance levels, attributed to additive factors responsive to selection, does not significantly deviate from 1. All of these results point to Ty-5 as the sole resistance locus in TY172 thus significantly increasing the likelihood of its successful molecular dissection. The DNA markers developed during the course of this study were transferred together with the TY172 genotype to Queensland. TY172 was crossed to a panel of Australian genotypes and the resulting populations were subjected to segregation analysis. Results showed that resistant locus, Ty-5, is highly reproducible in the Australian conditions as well. The Australian group was also able to make improvements to the marker assays by re-designing primer pairs to provide more robust PCR fragments. The Ty-5 locus has now been introgressed into elite Australian germplasm and selection for TYLCV resistance has begun. Cumulatively, our results show that Ty-5 can be effectively used, together with the TY172 genotype to expedite TYLCV resistance breeding and improve our understanding of the genetics that underline the response of tomato to TYLCV. Contributions to agriculture include: (1) the development of tools for more efficient resistance breeding, allowing the incorporation of resistance to local tomato varieties in Australia, Israel and elsewhere; and (2) establish a solid framework for a future attempt to clone the genes that encode such resistance. The latter will enable to decipher the resistance mechanisms that could be applied to other geminiviruses in tomato and possibly in other plant species.
