Neste trabalho, estudamos a formulação da distribuição de funções de variáveis aleatórias contínuas dependentes. O mecanismo de modelagem da dependência é feita via funções cópulas. Dentre os resultados obtidos formulamos a expressão geral da distribuição da soma de n variáveis aleatórias dependentes. Expandimos a abordagem para a distribuição de outras funções de variáveis aleatórias tais como o quociente, produto e uma combinação convexa. Por meio das R-Vines Cópulas, obtivermos também a expressão da soma de n variáveis aleatórias em que cada componente é governada por um processo GARCH. A partir deste resultado, calculamos o Value-at-Risk (VaR) e Expected Shortfalls (ES) da soma dessas variáveis. Em função desta estrutura, as medidas de risco passam a adquirir um comportamento dinâmico. Ao final do trabalho exibimos algumas ilustrações numéricas via simulação de Monte Carlo. Apresentamos também uma aplicação com dados reais provenientes de bolsas de valores da América Latina.
In this thesis, we studied the distribution of function of dependents continuous random variables. The modeling dependencies structures are made via copula functions. We obtain the general expression of the distribution of the sum of n dependents random variables. This approach is expanded for other functions such as ratio, product and a convex combination. Using R-Vines Copulas, we also derive an expression of the sum of n dependents random variables, being each component governed by AR-GARCH process. From these results, we assess the Value-at-Risk (VaR) and Expected Shortfalls (ES) of the sum of these variables. According to this structure, the VaR takes a dynamic behavior. At the end of this thesis, we show some numerical illustrations via Monte Carlo simulation. An application with real data from Latin American stock markets is also presented.

Full textENGLISH ABSTRACT: The quality of wine is largely dependent on environmental conditions and recent studies have therefore focused on agricultural practices in terms of water, soil and biodiversity conservation. The industry aims to create sustainable practice and to protect the natural resources available. Sources of potential grape contamination include: vehicle pollution, pesticides, bushfires and wood preservatives used for trellising systems. The latter have come to the attention of the South African wine industry (e.g. creosote and Copper Chromium Arsenate (CCA) products) as they may have consequences for the environment and wine quality. Creosote is a known pollutant of soil and ground water and the volatile fraction has been monitored in air. Plants may also accumulate polycyclic aromatic hydrocarbons (PAHs), which constitute up to 85% of the mass of creosote, and of which some have been proven carcinogenic. Because of the health risks associated with it, creosote has therefore been restricted for use in most applications in Europe, and also in the United States, Canada and Australia. This study focussed on the sensorial and chemical analyses of environmental and wine samples taken from the area around the creosote stockyard to determine accumulation of creosote-derived compounds. Environmental samples were collected and analysed at different distances from the affected area, over two vintages. Wines were made from grapes grown in vineyard blocks adjacent to the stockyard, to determine the effect of distance and skin contact during alcoholic fermentation treatments on wine taint. A sensory panel was trained for descriptive analysis to determine the intensity of the taint. Analytical methods were developed for the analysis of volatile organic compounds (VOCs) by gas chromatography mass spectrometry (GC-MS) and polycyclic aromatic hydrocarbons by high performance liquid chromatography with diode array detection (HPLC-DAD). The sensory results obtained showed white and rosé wines were perceived as clean, whilst the red wines were associated with burnt rubber/tar taint. The perceived taint decreased as distance from the stockyard increased. Wines made from the Cabernet Sauvignon blocks adjacent to the stockyard also showed an increase of taint with the increase of skin contact. Chemical data obtained showed that the taint consisted of a complex mixture of compounds, each with its own pattern of retention within the vineyard and wine. Only m-cresol was found above odour threshold, and only in red wines. The synergistic effect of some compounds may lead to an increase in the perceived taint. Berries and leaves had higher concentrations of volatile compounds than wines. Leaf contamination varied and followed the general trend in literature where the plants with high lipid content and exposed leaf area were the most contaminated. There may be other compounds present in creosote emissions, aside from those investigated here, with sensory attributes related to the taint found in wines. These compounds are styrene, indene, benzene, toluene, isoquinoline and quinoline and should be included in further investigations. From the PAH analysis of environmental samples and wines, it is evident that the samples closest to the stockyard were affected the most. The contamination varied with the depth of the soil: some of the heavier compounds were found in the samples taken from the deeper levels, whilst nearly all other target compounds were present in the top layer of soil. The concentrations found in the environmental samples were lower than reported in literature. Wines had few PAHs present, but at much higher concentrations than is allowed by EU legislation. From this study it is evident that the stockyard had negative effects on the surrounding environment in terms of sensory and chemical contamination. Recommendations include area rehabilitation by means of bioremediation to protect resources and ensure sustainable and safe production of crops. Industrial emissions should also be regulated and restricted in agricultural areas. Furthermore the use of creosote should be revised, and prohibited for agricultural use.
AFRIKAANSE OPSOMMING: Die kwaliteit van wyn is grootliks afhanklik van die omgewingstoestande. Daarom fokus verskeie onlangse studies op landbou aktiwiteite en die invloed daarvan op die omgewing in terme van water, grond en biodiversiteit bewaring. The wyn industrie se doelwitte sluit volhoubare praktyke in, wat die natuurlike hulpbronne bewaar en beskerm. Druiwe kan deur middel van die volgende bronne besoedel word: brandstof uitlaatgasse, insekdoders, veldbrande, gifstowwe wat gebruik word vir houtperservering wat dan verder aangewend word vir opleistelsels. Houtperservering (Koper chroom arsenaat (CCA) en kreosoot) het veral in die laaste paar jaar onder aandag gekom in die wynbedryf van Suid-Afrika as gevolg van die invloed daarvan op die omgewing en die uiteindelike wynkwaliteit. Kreosoot is ‘n gekende gifstof wat verantwoordelik is vir grond en grondwater besoedeling en wat gemonitor word in die atmosfeer. Plante akkummuleer ook poli-sikliese aromatiese hidro-koolstowwe (PAHs), wat to 85% uitmaak van die massa van kreosoot. PAHs is karsinogenies en dus is daar baie navorsing op die molekules reeds gedoen. Die gesondheidsrisikos gepaardgaande met kreosoot het gelei tot die streng geregulasies tans ingestel in Europa, die Verenigde State, Kanada en Australië. Hierdie studie het gefokus op die sensoriese en chemiese analises van omgewings- en wyn-monsters geneem van die omliggende area van die kreosoot palewerf om die akkumulasie van kreosoot-afgeleide-verbindings. Omgewingsmonsters was versamel en geanaliseer om verskillende afstande vanaf die bron van besoedeling (palewerf) te ondersoek oor ‘n twee jaar periode. Wyne is gemaak van die druiwe wat afkomstig is van die blok aangeplant langs die palewerf. Die wyne is ondersoek in terme van afstand vanaf die kreosoot bron asook oenologiese invloede, dopkontak gedurende alkoholiese fermentasie, op die kontaminasie beskryf in wyn. Die wyne is ook oor ‘n twee jaar periode voorberei en sluit die 2011 en 2012 seisoen in. ‘n Sensoriese paneel is opgelei om die beskrywende analises op die wyn uit te voer met die doel om die intensiteit van kontaminasie te identifiseer. Analitiese metodes is ook ontwikkel vir die analise van vlugtige organiese verbindings(VOCs) met gas chromatografie-massa spektrometrie (GCMS) en poli-sikliese aromaties hidro-koolstowwe (PAHs) met hoë druk vloeistof chromatografie. Die sensoriese resultate bekom het wit en rosé wyne as skoon laat blyk, terwyl rooi wyne meer geassosieer was met die gebrande rubber/ teer afgeur beskrywing. Die waargeneemde afgeur het afgeneem soos wat die afstand vanaf die palewerf toegeneem het. Wyne gemaak van die Cabernet Sauvignon blokke langsaan die palewerf het ook ‘n toename in die afgeur gehad met ‘n toename in dopkontak. Chemiese data bekom beeld uit dat die afgeur uit ‘n komplekse mengsel van verbindings bestaan, elk met sy eie patroon van verspreiding en verbinding in die wingerd as ook in die wyn. Net m-kresol was gevind bo die reuk drumpel, dit het ook net in rooi wyne voorgekom. Die sinergistiese effek van die verbindings mag egter bydra tot die waargeneemde afgeur. Druiwekorrels en blare het hoër konsentrasies van die vlugtige verbindings gehad as wat gemeet is in die wyne. Blaar kontaminasie het ook baie gewissel en het ooreengestem met die algemene tendens wat in literatuur beskryf is, naamlik dat plante met ‘n hoër lipid inhoud en grootter blaar oppervlak die meeste gekontamineer word. Daar mag egter nog baie ander verbindings bydra tot die waargeneemde afgeur gevind in die wyn. Spesifieke verbindings wat wel ‘n rol kan speel in kontaminasie en wat voorkom in die vlugtige gedeelte van kreosoot is styreen, indeen, benzeen, tolueen, isoquinoleen die vlugtige verbindings van kreosoot. Die verbindings moet ingesluit word vir verdere studies wat gedoen word op die kreosoot geassosieerde afgeur. Die PAHs analise op die omgewingsmonsters en wyne het gelei tot die bevestiging dat die naasliggende omgewing die meeste geaffekteer is. Die kontaminasie wissel in terme van die diepte in die grond wat die gifstowwe voorkom: die swaarder molekulêre verbindings is tot in die dieper vlakke waargeneem terwyl al die gemete verbindings in die boonste lae teenwoordig was. Die vlakke wat waargeneem is in dié studie is egter laer as wat voorheen in literatuur gevind is in ‘n kreosoot geaffekteerde omgewing. Wyn het PAHs teenwoordig gehad, alhoewel slegs twee verbindings gemeet is, het dit in hoër vlakke voorgekom as wat sekere Europese regulasies as toelaatbaar spesifiseer. Vanaf die studie resultate blyk dit, dat die palewerf se negatiewe invloed op die omliggende omgewing beide meetbaar was in sensories en chemiese kontaminasie. Voorstelle sluit onder andere die rehabilitasie van die omliggende omgewing deur middel van bioremediasie in. Om sodoende die natuurlike hulpbronne in die area te bewaar asook om volhoubare en veilige verbouing van gewasse te verseker. Industriële besoedeling en afval moet ook gereguleer word en beperk word in landbou areas. Verder moet die gebruik van kreosoot heroorweeg word en strenger regulasies moet in plek gestel word om aan internastionale standaarde te voldoen.

Full textENGLISH ABSTRACT: Twenty five commercial Chenin blanc wines produced solely from bush vine vineyards and including three vintages, three styles and five production areas, were sourced for this study. Descriptive sensory analysis (DSA) and chemical analyses including GC-FID (gas chromatography fitted with a flame ionisation detector) and FTMIR (Fourier transform mid-infrared) spectroscopy were employed to establish the sensory and chemical characteristics, whereas consumer tests were conducted to determine consumer perception and liking of bush vine Chenin blanc wines. DSA (a profiling technique) was also compared to the sorting task (a classification technique) with a description assignment to evaluate the sorting task’s ability to profile wines. According to the results of DSA, the wines separated into two groups. One group associated with sensory attributes which can be considered indicative of the Fresh and Fruity Chenin blanc style. The other group associated with sensory attributes which can be considered indicative of the Rich and Ripe style of Chenin blanc. No separation between the wooded and unwooded Rich and Ripe styles was apparent. According to the results of the chemical analyses, the wines also separated into two groups. This separation seemed to be caused by vintage and the chemical changes associated with ageing as the wines from the youngest vintage (2010) was strongly associated with high levels of esters and malic acid. The older wines were situated farthest away from these attributes indicating low concentrations. When comparing the results from the sorting task and DSA, it could be seen that similar wine style groupings formed, indicating that DSA can also be regarded as an effective tool when categorising wines. The differences in the positioning of some of the wines and attributes on the DSA multivariate plots and the sorting task plots could be attributed to the difference in panels used. The sorting task was conducted using an expert panel with persons illustrating significant technical knowledge of Chenin blanc wines. Experience, exposure and technical knowledge tend to establish a common language amongst wine experts which could have caused the expert panel to perceive some wines differently when comparing the results of the latter panel to that of the trained panel. DSA was found to remain the most effective method for establishing a comprehensive sensory profile. Consumer analyses showed that regular white wine drinkers prefer the unwooded styles (Fresh and Fruity and Rich and Ripe unwooded) of Chenin blanc more than the wooded style. It was also found that consumers with a higher level of objective wine knowledge tend to associate the terms ‘bush vine’ and ‘old bush vine’ with the Rich and Ripe style of Chenin blanc, whereas consumers with a lower level of objective wine knowledge associated ‘old bush vine’ with the Fresh and Fruity style. Since all the wines used in the consumer analysis were produced from old bush vines, it is evident that consumer education on the impact of bush vine training system and vine age on wine quality is needed. Better understanding of these principles could lead to elevated product appraisals and consumer satisfaction.
AFRIKAANSE OPSOMMING: Vyf en twintig kommersiële Chenin blanc wyne, uitsluitlik van bosstok wingerde geproduseer, is bekom vir hierdie studie. Die wyne het drie style, drie oesjare en vyf produksiestreke ingesluit. Beskrywende sensoriese analise (BSA) en chemiese analises, wat GC-FID (gas chromatografie gekoppel met vlam-ioniserende deteksie) en FTMIR (Fourier-transformering mid-infrarooi) spektroskopie insluit, is uitgevoer om onderskeidelik die sensoriese en chemiese eienskappe van die wyne te bepaal. Verbruikerstoetse is ook uitgevoer om verbruikerspersepsie en -voorkeure vir bosstok Chenin blanc wyne te bepaal. BSA (‘n profilerings tegniek) was ook vergelyk met ‘n sorterings taak (‘n klassifikasie tegniek) met ‘n beskrywings opdrag, primêr om die sorterings taak se vermoë om wyne te profileer te ondersoek. Volgens die resultate van BSA, het die wyne in twee groepe verdeel. Een groep het met die sensoriese eienskappe wat op ‘n Vars-en-Vrugtige-styl dui, geassosieër. Die ander groep het met sensoriese eienskappe geassosieër wat met die Volrond-styl verband hou. Geen verdeling tussen die gehoute en ongehoute wyne binne die Volrond-styl was sigbaar nie. Volgens die resultate van die chemiese analises, het die wyne ook in twee groepe verdeel. Die verdeling blyk asof dit veroorsaak is deur oesjaar en die chemiese veranderinge wat met wynveroudering gepaard gaan. Wyne van die jongste oesjaar (2010) het ‘n sterk verband met hoë vlakke van esters en appelsuur getoon. Die ouer wyne was verder weg van hierdie eienskappe geleë, wat op laer ester en appelsuur konsentrasies dui. Wanneer die meerveranderlike resultate van die sorterings taak (met en sonder die aanduiding van sensoriese eienskappe) en dit van BSA vergelyk word, kon soortgelyke groeperings gesien word. Dit is ‘n aanduiding dat BSA ook wyne effektief kan kategoriseer. Die verskil in posisionering van sommige wyne tussen die BSA en sorterings taak resultate, kan toegeskryf word aan die verskillende panele wat gebruik is om die tegnieke uit te voer. ‘n Deskundige paneel (wynkenners) is gebruik om die sortingstaak uit te voer. Ervaring, blootstelling en tegniese kennis is geneig om te lei tot die vestiging van ‘n gemeenskaplike taal onder wynkenners. Hierdie gemeenskaplike taal kan as rede aangevoer word vir die uiteenlopende analise van sommige wyne wanneer die resultate van die deskundige paneel met dié van die opgeleide paneel (in BSA gebruik) vergelyk word. Dit is gevind dat BSA, wanneer ‘n omvattende sensoriese profiel bepaal moet word, die mees effektiefste metode bly. Verbruikerstoetse het getoon dat gereelde witwyn-verbruikers die ongehoute Chenin blanc style (Vars-en-Vrugtig en ongehoute Volrond) bo die gehoute styl verkies. Dit is ook bepaal dat verbruikers met ‘n hoër vlak van objektiewe wynkennis neig om die terme ‘bosstok’ en ‘ou bosstok’ met die Volrond-styl van Chenin blanc te assosieer, terwyl verbruikers met ‘n laer vlak van objektiewe wynkennis die term ‘ou bosstok’ met die Vars-en-Vrugtige Chenin blanc styl assosieër. Aangesien al die wyne wat in die verbruikerstoetse ingesluit is van ou bosstok wingerde geproduseer is, is dit duidelik dat verbruikeropvoeding insake die effek van die gebruik van bosstokke en ou wingerdstokke op wynkwaliteit noodsaaklik is. ‘n Beter begrip van hierdie beginsels sal lei tot verhoogde produkwaardasie, asook ‘n toename in verbruikertevredenheid.

Full textThe experiment with an aim to study the effect of pruning types and effect of different types of organic amendments on soil quality, vine growth, grape production and wine quality was conducted in two sites located in Vilar and Sardoal region of Portugal. The pruning treatments included manual spur (MAN) and mechanical hedge (MEC) type of pruning and types of organic amendments applied were biochar (BIOC), municipal solid waste compost (RSUC), cattle manure (ESTR), sewage sludge (ETAR) and control treatment (TEST). The treatment effects were analyzed for chemical composition, mineral content and heavy metals content and sensorial analysis of wine samples. The analysis results show that there was no significant effect of type of pruning on wine composition except pH, total acidity, alcohol content, calcium and total nitrogen content of wine sample. Similar trend was also followed with the application of organic amendments; the composition of wine remained unchanged by the use of organic amendments except some effect on pH, total acidity, volatile acidity, total anthocyanins and potassium content of wine samples. There was no significant increase in the heavy metals content of wine samples after the treatment of organic amendment. The manual pruning generally showed higher content compared to mechanical pruning due to less number of bunches retained per shoots. Wine composition was more influenced by the site specific characters and climatic conditions than the effect of treatment applied. Sensory analysis along with chemical analysis shows that mechanical pruning can be used without having much significant effect on grape composition when sufficient yield compensation is achieved. Treatment which supplied higher amount of nitrogen (ETAR and ESTR) was generally marked by more negative sensory perception such as vegetal characters in wine. On the face of climate change and increased competitive pressure use of mechanical pruning can be good strategy to reduce the cost of grape production and organic amendment can be applied to soil with an aim of increasing organic matter contents of soil. But the care should be taken to avoid excessive supply of nitrogen in order to avoid negative effect on wine composition over longer period of time. So the supply of amendment should be managed according to vine and soil nutritional status

Resumo: Lianas são plantas que germinam no solo, mantêm-se enraizadas durante toda a vida e necessitam de suporte físico para alcançarem o dossel. Elas são membros característicos das florestas tropicais, onde contribuem com cerca de 25% da diversidade vegetal. Às vezes, dominam a vegetação, principalmente em áreas perturbadas. Lianas competem com árvores por nutrientes e luz, e influenciam a taxa de crescimento e a mortalidade de sua árvore hospedeira. Embora as lianas iniciem sua escalada a partir do chão, muitas colonizam árvores vizinhas pelo dossel da floresta, ¿amarrando-se¿ às outras, podendo ocasionar a queda de várias árvores quando uma delas cai. Devido a sua abundância e o seu impacto sobre as árvores, é de grande importância conhecer os fatores que governam a distribuição e dinâmica das lianas na floresta tropical e, assim, desenvolver estratégias de uso sustentável. Assim, os objetivos desta tese foram: (1) avaliar a riqueza e abundância das lianas e (2) a relação das lianas com as características do hospedeiro e com a estrutura da floresta. O trabalho foi realizado em um fragmento de floresta estacional semidecidual, com cerca de 435,73 ha, na Estação Ecológica de Paulo de Faria, SP. Foram amostradas 100 parcelas de 10 x 10 m (1 ha). As lianas com diâmetro ³ 1 cm e as árvores ³ 3 cm enraizadas nas parcelas foram medidas no DAP (diâmetro à altura do peito - 1,30m) e identificadas. Amostrou-se 1427 indivíduos de 45 espécies de lianas, pertencentes a 14 famílias, sendo as mais ricas: Bignoniaceae (14 espécies), Sapindaceae (nove) e Malpighiaceae (seis), e as mais abundantes Bignoniaceae, Sapindaceae e Apocynaceae. A riqueza de lianas foi aproximadamente igual à metade (razão 0,51) da riqueza de árvores (87 espécies). A densidade média de lianas e árvores foi semelhante, cerca de 1400 indivíduos/ha. Melloa quadrivalvis (Bignoniaceae) foi a espécie mais comum na área estudada. Do total de indivíduos de lianas amostrados, 57,6% apresentaram diâmetros entre 1 - 2,5 cm, correspondendo a 95% da riqueza total amostrada. Das 1419 árvores amostradas, 53% carregavam pelo menos uma liana. As espécies menos infestadas que a média geral foram Inga marginata, Piper amalago, Trichia catigua e T. claussenii, e somente uma, Machaerium paraguariense, foi mais infestada que a média, considerando todas as espécies. Os resultados, de modo geral, não apoiaram a hipótese de especificidade entre espécies de lianas e espécies de árvores, pois a riqueza e a diversidade de espécies de lianas aumentaram com a proporção de infestação. Se houvesse especificidade, esperar-se-ia que uma espécie de árvore fosse mais infestada por uma determinada espécie de liana. O mecanismo de escalada das lianas não influenciou o número de árvores que cada liana escalou, embora tenha ocorrido associação positiva entre árvores com casca rugosa e lianas com gavinhas. Considerando-se as características individuais do hospedeiro, as árvores com diâmetros maiores apresentaram maior densidade de lianas. Com relação às características da vizinhança, as diferenças encontradas provavelmente se devem as condições de luminosidade do ambiente. As parcelas com maior proporção de árvores com DAP > 30 cm apresentaram relação negativa significativa com a densidade de lianas. A relação foi positiva em parcelas com maior proporção de árvores com copas £ 3 m de altura. Assim, as evidências deste estudo sugerem que a distribuição das lianas foi mais influenciada por características da comunidade do que pelas características das espécies de árvores presentes
Abstract: Lianas are soil-germinating plants, perennially rooted and which need support to reach the canopy. They are characteristically from the rain forests, where they contribute with near 25% of vegetal diversity. Lianas compete with trees for nutrients and light, influencing growth and mortality rates of its host tree. Although lianas begin their life on the ground, many of them colonize vicinity trees through the forest canopy, ¿tying¿ themselves to the others, and may cause the fall of many trees. Due to their abundance and impact over other trees, it is important to know the factors governing distribution and dynamics of the lianas in order to better understand the rain forest and to develop sustainable strategies. Thus, the aims of this study were: (1) to assess the richness and abundance of lianas, and (2) to establish the relation of lianas with the characteristics of the hosts and the structure of the forest. The research was carried out in a fragment of a Semideciduous Stational Forest with 435.73 ha, at the Paulo de Faria Ecological Station. The sampling consisted of 100 plots of 10 x 10 m (1 ha), allotted in an area of 4 ha. Lianas with a diameter ³ 1 cm and trees ³ 3 cm rooted in the plots were measured in DBH (diameter at breast height ¿1.30m) e identified. In the study area, 1427 individuals were sampled from 45 species of lianas, belonging to 14 families, the richest ones being Bignoniaceae (14 species), Sapindaceae (nine) e Malpighiaceae (six), and the more abundant Bignoniaceae, Sapindaceae e Apocynaceae, adding up to 80% of the sampled individuals. The liana richness was approximately equal to half (ratio 0.51) the tree richness (87 species). Average density of lianas and trees was similar, around 1400 individuals/ha. Melloa quadrivalvis (Bignoniaceae) was the most common species in the study area. From the total number of the sampled liana individuals, 57.6% presented diameters between 1- 2.5 cm, corresponding to 95% of the total sampled richness. Only 26 individuals presented diameter higher than 10 cm. From the 1419 trees with diameter ³ 3 cm, 53% carried at least one liana, with the higher rate of infestation (79%) occurred in the individuals with diameters > 10 cm. Species less infested than the expectation were Inga marginata, Piper amalago, Trichia catigua e T. claussenii. One species, Machaerium paraguariense, was more infested than the expectation. In general, results did not support the hypothesis of species-specificity between lianas and trees, since the richness and diversity of liana species increased with the infestation rate. Climbing mechanism did not influence the number of trees climbed by each liana, although we have found positive association between wrinkled bark and tendrils. Considering the individual characteristics of the host, trees with larger diameters showed higher density of lianas. In relation to the vicinity characteristics, the plots with higher rate of big trees (DBH > 30 cm) showed significant negative relation with the density of lianas. The relation was positive in plots with higher rate of trees with small crown (£ 3 m). Thus, our study showed the association between tree and vicinity characteristics with infestation and density of lianas

Full textThe vine is susceptible to many fungal diseases that will affect the quality of grapes and wines. For several years, Esca has become the bane of modern viticulture because it is responsible for the death of the vines when presented in the form apoplectic. Its chronic form is associated with the presence of a procession of pathogenic fungi in the trunk and arms that will most often cause leaf symptoms. The alteration of photosynthesis that this causes will affect fruit ripening. However, little research has been conducted to characterize precisely the impact of this disease on the metabolism and chemical composition of grape berries. Our study aimed to assess, using a proteomic approach the disease's impact on the quality of grapes and get specific markers. Our work allowed us to demonstrate that the expression of foliar symptoms of Esca causes a change in abundance of proteins related to defense mechanisms and oxidative stress in the grape skin. It is also observed a change in antioxidant capacity by modulating levels of hydrogen peroxide, glutathione or pyridoxine. The concentrations of molecules of oenological interest such as amino acids, biogenic amines or tannins are also modified in the presence of foliar symptoms of Esca

This would have consequences for larval performance, as well as resulting in ecological and behavioral changes. Corresponding studies in the Campos de Cima da Serra region, inexist. This region has a distinct of Passifloraceae flora. In this study, it was quantified a population of adults of H. ethilla narcaea in Floresta Nacional de São Francisco de Paula, RS, region of Araucaria Forest, in March 2006 to May 2007. In laboratory conditions, it was tested the influence of seven species of Passiflora (P. alata, P. actinia, P. caerulea, P. capsularis, P. edulis, P. suberosa and P. misera) on larval performance and size of adults. Larval feeding preferences were evaluated through leaf disk, for first and fifth instars, using double choice tests, when created individually in different passion vines and, multiple, when created in P. alata. The corresponding induction was determined testing it preference of that passion vine species used in creation, compared with excessively, in double choice tests. Larval survivorship was greatest on P. alata, P. caerulea, P. actinia, P. edulis and P. misera. Development time was fewer in P. misera and, the size of adults, was better in P. edulis. In double choice tests, larvae preferred plants which they had been servants, in majority of cases. Larvae chose P. edulis, P. misera, P. actinia, on multiple choice tests, which conferred less development time. Thus, our data suggest that H. ethilla narcaea is developed satisfactorily in many species of Passifloraceae, for which can present induction of feeding preference (learning in the larval stage). Depending on association in qualitative and quantitative variation of these host plants to behavior of larval choice (feeding) on part of adults (oviposition), which need to be tested, will be able to have local specializations. The existence of induction in feeding preference in larval stage, Hopkins’ effect (influence of larval experience in the choice of adult) and/or associative learning of females in relation to host species could take a geographic differentiation in evolution of host plants use by this butterfly.

Full textENGLISH ABSTRACT: Metagenomic studies that make use of next-generation sequencing (NGS) generate large amounts of sequence data, representing the genomes of multiple organisms of which no prior knowledge is necessarily available. In this study, a metagenomic NGS approach was used to detect multiple novel mycoviral sequences in grapevine phloem tissue. Individual sequencing libraries of doublestranded RNA (dsRNA) from two grapevine leafroll diseased (GLD) and three shiraz diseased (SD) vines were sequenced using an Illumina HiScanSQ instrument. Over 3.2 million reads were generated from each of the samples and these reads were trimmed and filtered for quality before being de novo assembled into longer contigs. The assembled contigs were subjected to BLAST (Basic Local Alignment Search Tool) analyses against the NCBI (National Centre for Biotechnology Information) database and classified according to database sequences with which they had the highest identity. Twenty-six putative mycovirus species were identified, belonging to the families Chrysoviridae, Endornaviridae, Narnaviridae, Partitiviridae and Totiviridae. Two of the identified mycoviruses, namely grapevine-associated chrysovirus (GaCV) and grapevine-associated mycovirus 1 (GaMV-1) have previously been identified in grapevine while the rest appeared to be novel mycoviruses not present in the NCBI database. Primers were designed from the de novo assembled mycoviral sequences and used to screen the grapevine dsRNA used for sequencing as well as endophytic fungi isolated from the five sample vines. Only two mycoviruses, related to sclerotinia sclerotiorum partitivirus S and chalara elegans endornavirus 1 (CeEV-1), could be detected in grapevine dsRNA and in fungus isolates. In order to validate the presence of mycoviruses in grapevine phloem tissue, two additional sequencing runs, using an Illumina HiScanSQ and an Applied Biosystems (ABI) SOLiD 5500xl instrument respectively, were performed. These runs generated more and higher quality sequence data than the first sequencing run. Twenty-two of the putative mycoviral sequences initially detected were detected in the subsequent sequence datasets, as well as an additional 29 species not identified in the first HiScanSQ sequence datasets. The samples harboured diverse mycovirus populations, with as many as 19 putative species identified in a single vine. This indicates that the complete virome of diseased grapevines will include a high number of mycoviruses. Additionally, the complete genome of a novel endornavirus, for which we propose the name grapevine endophyte endornavirus (GEEV), was assembled from one of the second HiScanSQ sequence datasets. This is the first complete genome of a mycovirus detected in grapevine. Grapevine endophyte endornavirus has the highest sequence similarity to CeEV-1 and is the same virus that was previously detected in fungus isolates using the mycovirus primers. The virus was detected in two fungus isolates, namely Stemphylium sp. and Aureobasidium pullulans, which is of interest since mycoviruses are not known to be naturally associated with two distinctly different fungus genera. Mycoviral sequence data generated in this study can be used to further investigate the diversity and the effect of mycoviruses in grapevine.
AFRIKAANSE OPSOMMING: Metagenomiese studies, wat gebruik maak van volgende-generasie volgordebepalingstegnologie, het die vermoë om die genetiese samestelling van veelvoudige onbekende organismes te bepaal deurdat dit groot hoeveelhede data genereer. Die bogenoemde tegniek was in hierdie studie aangewend om aantal nuwe mikovirusse in die floëem weefsel van wingerd te identifiseer. Dubbelstring-RNS was gesuiwer vanuit twee druiwestokke met rolbladsiekte en drie met shirazsiekte en Illumina HiScanSQ instrument is gebruik om meer as 3.2 miljoen volgorde fragmente te genereer van elk van die monsters. Lae-kwaliteit volgordes was verwyder en die oorblywende kort volgorde fragmente was saamgestel om langer konstrukte te vorm wat met behulp van BLAST soektogte teen die NCBI databasis geïdentifiseer kon word. Ses-en-twintig mikovirus spesies, wat aan die families Chrysoviridae, Endornaviridae, Narnaviridae, Partitiviridae en Totiviridae behoort, was geïdentifiseer. Twee van die geïdentifiseerde mikovirusse, naamlik grapevine-associated chrysovirus (GaCV) en grapevine-associated mycovirus 1 (GaMV-1), was voorheen al in wingerd gekry terwyl die res nuwe mikovirusse is wat tans nie in die NCBI databasis voorkom nie. Inleiers was ontwerp vanaf die saamgestelde mikovirus basisvolgordes en gebruik om wingerd dubbelstring-RNS sowel as swamme wat vanuit die wingerd geïsoleer is te toets vir die teenwoordigheid van hierdie mikovirusse. Slegs twee mikovirusse, wat onderskeidelik verwant is aan sclerotinia sclerotiorum partitivirus S en chalara elegans endornavirus 1 (CeEV-1), kon deur middel van die inleiers in wingerd en swam isolate geïdentifiseer word. Twee addisionele volgordebepalingsreaksies, wat gebruik gemaak het van die Illumina HiScanSQ en ABI SOLiD 5500xl volgordebepalingsplatforms, was gebruik om die teenwoordigheid van mikovirusse in wingerd te bevestig. Groter hoeveelheid volgorde fragmente was geprodusser wat ook van hoër gehalte was as dié van die eerste volgordebepalingsreaksie. Twee-en-twintig mikovirus spesies kon weer geïdentifiseer word, sowel as 29 spesies wat nie in die eerste HiScanSQ basisvolgorde datastelle gevind was nie. Die wingerdstokke wat in hierdie studie ondersoek was, het hoë diversiteit van mikovirusse bevat aangesien daar tot 19 mikovirus spesies in enkele wingerdstok geïdentifiseer was. Dit is aanduiding dat volledige virus profiele van siek wingerdstokke aantal mikovirusse sal insluit. Die vollengte genoomvolgorde van voorheen onbekende endornavirus was saamgestel vanuit een van die tweede HiScanSQ volgorde datastelle. Dit is die eerste mikovirus wat in wingerd gevind word waarvan die volledige genoomvolgorde bepaal is en ons stel die naam grapevine endophyte endornavirus (GEEV) voor vir hierdie virus. Grapevine endophyte endornavirus is die naaste verwant aan CeEV-1 en is dieselfde virus wat voorheen in wingerd dubbelstring-RNS en swam isolate gevind was deur middel van die mikovirus inleiers. Swam isolate waarin GEEV gevind is, was geïdentifiseer as Stemphylium sp. en Aureobasidium pullulans. Dit is van belang dat GEEV in twee swam isolate gevind is wat aan verskillende genusse behoort aangesien hierdie verskynsel nog nie voorheen in die natuur gevind is nie. Mikovirus nukleiensuurvolgordes wat in hierdie studie bepaal was kan gebruik word in toekomstige studies om die verskeidenheid en impak van mikovirusse in wingerd verder te ondersoek.

Full textEm dietas para coelhos de corte, o feno de alfafa figura como o ingrediente de maior custo. Desta forma, substituí-lo por resíduos agrícolas reduz os custos dos produtos cunículas. Além disso, o uso de resíduos reduz passivos no meio ambiente e melhora a sustentabilidade da cadeia produtiva. Dois ensaios foram realizados no Laboratório de Cunicultura do Departamento de Zootecnia, da Universidade Federal de Santa Maria, onde se estudou a influência de diferentes substratos, em substituição ao feno de alfafa, em dietas para coelhos de corte. O objetivo do primeiro estudo foi avaliar a viabilidade do uso de topos de cenoura (CT), em substituição ao feno de alfafa, em dietas para coelhos de corte. Para tal, utilizou-se 30 coelhos da raça Nova Zelândia, desmamados aos 35 dias de idade, divididos em três grupos, submetidos aos seguintes tratamentos: T0CT - dieta controle sem inclusão de TC; T25CT dieta com 25% de substituição do feno de alfafa por CT e T50CT dieta com 50% de substituição do feno de alfa por CT. O ensaio biológico teve duração de 49 dias. Os parâmetros avaliados foram: ganho de peso, conversão alimentar, consumo de ração e viabilidade econômica da dieta. Verificou-se que o ganho médio diário de peso dos animais foi de 23,93g no T0CT, 22,65g no T25CT e 22,16 no T50CT. Já o consumo diário de ração foi de 86,71g no T0CT, 88,43g no T25CT e 89,57g no T50CT. Ainda o custo por kg de dieta reduziu linearmente com a inclusão dos TC em substituição ao feno alfafa, sendo a dieta T0CT a mais onerosa (R$0,74/kg) e a T50CT (R$0,60) a mais econômica. Concluiu-se que os CT podem substituir até 50% o feno de alfafa em dietas para coelhos em crescimento, otimizando o custo da dieta sem prejudicar o desempenho dos animais. O objetivo do segundo estudo foi determinar o efeito da substituição do feno de alfafa por baraço de batata-doce (SPV) sobre o desempenho, a carcaça e parâmetros de metabolismo hepático de coelhos de corte. Para tal, 27 coelhos Nova Zelândia (variedade branca) foram desmamados aos 35 dias e divididos em três tratamentos: 0SPV dieta sem a inclusão de SPV; dieta 10SPV com 10% de feno de alfafa substituído por SPV; e 15SPV dieta com 15% de feno de alfafa substituído por SPV. O ensaio durou 49 dias. O consumo diário de ração variou entre 73,17g e 78,02g; com ganho de peso diário entre 22,32g e 23,17g; e a conversão alimentar entre 3,16 a 03,49 e o peso vivo final entre 1839,44g e 1880,55g. Nenhum desses parâmetros de desempenho foi significativamente afetado pelos tratamentos dietéticos. Quanto aos dados pós-abate, os tratamentos não diferiram em peso da carcaça e do coração. No entanto, o peso do fígado foi significativamente menor nos animais do tratamento 10SPV. A glicose presente no fígado variou de 1,62mg/g-1 no grupo 10SLP a 5,02mg/g-1 no 15SPV e 5,6 mg/g-1 no grupo de controle (0SPV). A glicose liberada no tecido apresentou concentração de 2,35μmol, 2,13μmol e 2,59μmol liberado/g de tecido nos tratamentos 0SPV, 10SPV e 15SPV, respectivamente. Por conseguinte, concluiu-se que o SPV pode ser incluído em até 15% em substituição ao feno de alfafa, sem afetar negativamente o desempenho dos animais.

Para ello en primer lugar esta tesis estudia el efecto de la madurez de la uva sobre las propiedades espumantes de los vinos espumosos para llegar a la conclusión de que una excesiva maduración de la uva perjudica las características espumantes. A continuación se aborda el estudio de los efectos del uso de levaduras No Saccharomyces mediante inoculación secuenciada con Saccharomyces cerevisiae sobre las características de vinos base para Cava, llegándose a la conclusión de que el uso de la levadura Torulaspora delbrueckii puede ser muy útil para mejorar las propiedades espumantes. Finalmente, se aborda el estudio del efecto de una levadura altamente productora de polisacáridos y de la suplementación con levaduras secas inactivas sobre la composición y calidad del vino tinto, llegándose a la conclusión de que ambos procedimientos conllevan un enriquecimiento del vino en polisacáridos y una cierta disminución de su concentración en proantocianidinas, especialmente de las de alto grado de polimerización.
This paper deals with the study of how to mitigate the effects of climate change on the production of sparkling wines and red wines using the tools of biotechnology currently offers. With this aim, this thesis studies the influence of the maturity level of the grapes on the foaming properties of sparkling wines to conclude that excessive ripening of the grapes affects negatively. The work continues with the study of the effects of No-Saccharomyces yeasts on the composition of base wine of Cava, leading to the conclusion that the use of the yeast Torulaspora delbrueckii can be very useful to improve foaming properties. Finally, this work studies the effect of a yeast with a high polysaccharide releasing capacity and of the supplementation with inactive dry yeast on the composition and quality of red wine. The results indicate that both procedures enrich the wine on polysaccharides and decrease its concentration in proanthocyanidins, especially those with high degree of polymerization..

Full textA recent phenomenon is the introduction in the law of less legal concepts with higher elasticity, which give the judge a broader discretion. This is the case for the concept of vulnerability. Although vulnerability was never completely absent from our law, more amazing is the fact that this notion is taken into consideration in the jurisprudence relating to defects of consent even if in contradiction with the texts of the Civil Code. If this term has been used it is because the Jurisprudence has since a long time distorted the meaning of the texts. To better understand this concept, a detour by other institutions will determine its future concerning defects of consent. The different French or European projects of contract law reform are also considering this notion. However, these discussions demonstrate that its introduction in the texts relating to the defect of consent is challenging

Full textThe formation of protein haze in white wines during storage and transportation is a constant concern of the winemakers. Clarity of these wines is one of the prior quality aspects. This type of haze can occur easily with in bottled wines which are exposed to changes of temperatures. Sauvignon blanc grapes develop during ripening the characteristic aromas of the variety. At this time also increases the content of proteins that influence in the future stability and organoleptic characteristics of the wine. Due to the climate conditions of the viticulture oasis of Cuyo (solar radiation and temperature) achieve a proper content of aromas in Sauvignon blanc is not an easy task. This leads to find fining methods that respect the majority aromatics compounds of these wines. The wines produced in this region have a lot amount of protein derived from grapes, they requires higher doses of bentonite in comparison to other varieties. To avoid these problems, the wines are clarified with high doses of bentonite which leads to the loss of the majority varietal aromas. In this paper the application of alternative treatments to bentonite was studied with the objective of replacing its use for the removal of proteins. Mannoproteins, added or released from the cell walls of yeasts were used and oenological tannins. The study of stability in wines was the heat test, technique widely used by the wine industry. Also the estimation of the molecular weights of the proteins by polyacrylamide gel electrophoresis technique was made. It was observed that the only effective treatment for preventing the protein haze was the use of bentonite. The application of other products does not remove completely the proteins that cause the haze. However, in combination with low doses of bentonite, stables wines were obtained. It would make Sauvignon blanc wines keep the aromas coming from the grape.

To identify occurring design factors, a visual content analysis was made from three different price ranges brought from the Swedish Alcohol Retailing Monopoly’s website. Based on the visual content analysis results three wine labels for each price range was designed. To find out if these design factors were associated with the intended price range, the wine labels were tested on consumers with a web survey. The conclusion was that there was some general features that distinguish price range classes, although many design elements were common for all price ranges. Based on the respondents answers it turned out that some of the design factors were more or less clear to the intended price range.

Full textA partir de los documentos revisados para la elaboración de la presente monografía es posible señalar que la poda mecánica de vides surge hace más de 60 años, con el fin de reducir los costos de producción y aumentar la rentabilidad de viñedos. Si bien la poda mecánica permite podar vides a menor costo que la poda manual tradicional, lo hace en forma menos precisa. Esto se traduce en un aumento del número de yemas retenidas por planta, lo que activa una serie de respuestas fisiológicas que, de no ser abordadas, pueden complicar el manejo del viñedo y perjudicar la calidad de la uva y del vino. En la actualidad existen diversas experiencias que validan la correcta adecuación a la poda mecánica bajo ciertas condiciones agroecológicas. Sin embargo, la complejidad del análisis ha conducido a generar una resistencia a su implementación, siendo posible encontrar muchos casos donde, a pesar de las presiones económicas, la poda mecánica es aun parcial o definitivamente no se aplica. La recopilación de antecedentes realizada indica que entender el comportamiento de la vid y los factores que interactúan al imponer algún tipo de poda mecánica es clave para lograr una adecuada adaptación a dicho sistema y de ese modo rentabilizar la producción de uva para elaboración de vino.

Full textThe study takes into account the polyphenolic composition of Meriot, Cabernet-Sauvignon and Tannat grapes and wines fTom vineyards located in the South of Uruguay. Different cultural and environmental situations were considered, including vines conducted in lyre and trellis in the three varieties, cluster thinning in veraison in Meriot and Cabernet-Sauvignon and cordon Royat pruning and Guyot pruning in Tannat lyre. Tannat grapes presented the highest contents of sugar, total polyphenols, total and extractable anthocyanins, non-acylated and coumarylic anthocyanins. Tannat wines presented the highest contents of alcohol, total acidity, dry extract, total polyphenols, total and ftee anthocyanins, catechins and proanthocyanidins. They also were the most coloured, the reddest and darkest wines and those with the highest proportions of ionised anthocyanins and the most polymerised and condensed tannins. The average anthocyanic profiles of the wines of the three varieties were similar to those obtained in the respective skin extracts. Tannat grapes and wines had the highest non-acylated glucosides, petunidin and delphinidin proportions; Cabernet-Sauvignon presented the highest acetylated glucosides and malvidin proportions, whereas Meriot presented the highest coumarylic glucosides and peonidin proportions. Lyre conduction in Meriot allowed to obtain the highest yields and the grapes with the highest sugar and anthocyanin contents. Consequently, wines of this variety conducted in lyre had the highest alcohol, polyphenols and anthocyanins contents than those ftom trellis. Ln aIl the situations studied, the "year" effect was very significant, especially in relation to the polyphenolic composition of grapes and wines of the three varieties. The definition of the duration of the maceration for each variety, on the basis of the indices determined for the grapes in the maturity, the assays in the laboratory and the follow up of the polyphenols extractions in the vinification, allowed to establish extremely high correlations between the polyphenolic potential of the grapes and the colour and the phenolic composition of the wine. The knowledge of the anthocyanic and tannins richness of the grapes and its extractability allow to improve the management of the vinification and the prediction of some of the wines characteristics, such as its colour and phenolic composition

Full textL'estudi apunta tot seguit els condicionaments literaris que determinaren l'emigració de Vinyes a Colòmbia el 1913, on s'establí a Barranquilla des de 1914. L'autor de la tesi aprofundeix en el paper com a teòric i orientador exercit en aquell país durant la seva estada entre 1913 i 1925. Bona part de l'apartat és ocupat per l'estudi de la revista Voces de Barranquilla (1917-1920), de la qual fou el principal impulsor i que representà una de les principals plataformes de l'avantguarda a Hispanoamèrica. Hi adquireixen relleu les posicions que sobre estètica literària i art dramàtic hi adoptà Vinyes. Malgrat la distància colombiana, es trobava en ple seguiment de la cultura catalana i europea: es destaca el paper revulsiu de Voces en autors colombians contraris a tota restricció acadèmica, estètica o moral damunt del fet literari.
El nucli de la tesi, desenvolupat en els capítols 5 i 6, analitza la producció i recepció de les peces estrenades, editades o inèdites de Vinyes durant el fecund període 1926-1939, en connexió amb els seus nombrosos posicionaments crítics. Aquesta panoràmica s'insereix dins el context literari català, singularment després de l'estrena de Llegenda de boires (1926), que significà el reingrés a l'escena barcelonina amb una polèmica recepció. Hom subratlla el seguiment respecte de revulsius models foranis: l'expressionisme alemany -Bertolt Brecht- o la via lírica de Jean Giraudoux, per exemple. Les expectatives desvetllades per les seves conferències i escrits de 1928-1929, resten confirmades en obres com Viatge (1927 ), Qui no és amb mi...(1929), Peter's Bar. (1929) o Ball de titelles (1936), farsa antiburgesa que representa a parer de Lladó una de les seves vies més consolidades en el camp creatiu. Durant el període de la Segona República, la tesi incideix en les orientacions polítiques de la seva obra, amb èmfasi en el compromís de les seves posicions durant els anys de la Guerra Civil. L'avinentesa dels seus articles com a crític de rereguarda atent als posicionaments d'Erwin Piscator o l'estrena d'obres com Comiats a trenc d'alba (1938) i Fum sobre el teulat (1939), confirmen la implicació dins el moment històric, coherent amb els plantejaments antiburgesos d'anys precedents.
Lladó recalca en les conclusions el paper de Vinyes en el teatre català, a mig camí dels principis tràgics d'inicis de segle i l'expectativa de modernització que significaren les seves propostes durant els anys 20 i 30. L'estudi és coronat amb un apèndix ampli que conté significatius textos teoricocrítics redactats entre 1917 i 1939 i una vasta bibliografia que fixa i data el conjunt de la producció literària de l'autor: s'hi inclouen nombrosos escrits inèdits classificats en el Fons Ramon Vinyes de l'Arxiu Comarcal de Berga, fruit d'una donació dels hereus de l'escriptor a la qual contribuí l'autor de la tesi.
"Ramon Vinyes and the Theater (1904-1939)" studies the trajectory of this Catalan writer (Berga, 1882-Barcelona, 1952) who was immortalized as "The Wise Catalan", one of the characters in Gabriel García Márquez' novel One Hundred Years of Solitude.The study focuses on his activity as a playwright, paying special attention to the period from 1925 to 1939, during which he was a prominent figure in Catalonia.The first chapters examine his origins against the background of the "Renaixença" (Catalonia's nineteenth century literary renaissance) and the social, political and ideological environment of Berga, his hometown. Starting in 1904 when his first plays were staged, came into light his work is analyzed in connection with the theatrical theories defended by the last generations of Catalan Modernism and the first ones of the movement that followed it: the"Noucentisme". In this period of transition Vinyes chose a style of tragedy inspired by Ibsen, D'Annunzio, Hauptmann, Maeterlink..., which were models to the Modernists, defying thereby many of the esthetic and commercial guidelines followed by the theatrical community and the critics in Barcelona around 1910.
Next, the study delves into the literary climate that determined Vinyes' emigration to Colombia in 1913, where he settled in Barranquilla the following year. The thesis deepens on the leading role as a theoretician that Vinyes played in that country between 1913 and 1925. This section devotes mainly to the study of the Barranquilla's magazine Voces (1917-1920), which he promoted and which became one of the main platforms for the avant-garde in Latin America. Vinyes' positions regarding literary esthetics and dramatic arts are emphasized. Despite the geographical distance Vinyes followed Catalan and European culture very closely. The study points out the thought-provoking impact that Voces had on Colombian authors opposed to any academic, esthetic or moral restriction on the literary act.
The core of the thesis, developed in chapters 5 and 6, analyzes the production and reception of Vinyes' staged, edited and unpublished plays, during the productive 1926-1939 period, establishing links with his numerous critical positions. This survey is placed in the context of Catalan Literature, particularly after the opening of Llegenda de boires (1926), which represented his controversial return to Barcelona's theater scene.The study emphasizes the influence on his work of groundbreaking foreign models: German Expressionism -Bertolt Brecht- or Jean Giraudoux' lyrical mode, for instance. The expectations aroused by his talks and writings of 1928-29 are fulfilled in plays such as Viatge (1927), Qui no és amb mi...(1929), Peter's Bar (1929), or Ball de titelles (1936), an anti-bourgeois farce which is deemed to be one of his strongest suits in the creative field. In the Spanish Republican period, the thesis delves into the political leanings of Vinyes' work, emphasizing his commitment during the years of the Civil War. The timeliness of his articles as a critic behind the lines who was paying attention to Erwin Piscator's perspectives besides the opening of plays such as Comiats a trenc d'alba (1938) and Fum sobre el teulat (1939), confirm his implication in the historical moment, consistent with anti-bourgeois stance of preceding years.
Lladó emphasizes in his conclusions Vinyes's role in Catalan theater, midway between the tragical principles of the beginning of the century and the expectations of modernization that his literary proposals represented during the 20's and 30's. The study concludes with an extensive appendix featuring significant theoretical and critical texts written between 1917 and 1939, as well as a vast bibliography that catalogues the author's entire literary production. The bibliography includes the unpublished writings archived in the "Ramon Vinyes Foundation" at the "Arxiu Comarcal de Berga" (Berga's regional records), the result of a donation by the writer's heirs to which the author of this thesis also contributed.
