Root restriction, under-trellis cover cropping, and rootstock modify vine size and berry composition of Cabernet Sauvignon

Hill, Brycen Thomas 02 March 2017 (has links)
Vineyards in the Mid-Atlantic often have large, vigorous vines that can be costly to manage and produce inadequate fruit for wine production. Dense canopies increase the incidence of fungal disease, require greater allocation of resources to manage, and inhibit fruit development. The primary objective of these studies was to determine effective vine-size modification treatments that would optimize fruit quality, while reducing labor and chemical control. Research factors included root manipulation, under-trellis ground cover, and rootstock. Treatment levels were root bag (RBG) or no root manipulation (NRM); under-trellis cover crop (CC) or herbicide strip (HERB); and one of three rootstocks: 101-14, Riparia Gloire, or 420-A. Effects of these treatments were measured in two experiments: Experiment I compared combinations of all three treatments, while Experiment II explored the individual effects of root restriction using root bags of varying volumes. Root restriction consistently demonstrated the ability to reduce vegetative growth and vine water status. In the first experiment fruit-zone photosynthetic photon flux density (PPFD) was increased by 234% in RBG vines. Timed canopy management tasks indicated that RBG canopies required about half the labor time of NRM canopies. Anthocyanin concentration and total phenolic content were increased by 20% and 19% respectively in RBG fruit. CC increased fruit-zone PPFD by 62%, and increased soluble solids and color compounds. The 420-A rootstock reduced potassium uptake, resulting in lower must potassium concentration. Results demonstrated that these treatments significantly reduce vegetative growth in a humid climate, decrease management labor, and produce higher quality fruit. / Master of Science

在中國現代文學中,文藝與政治之間有著密切而複雜的關係,此一問題在現代戲劇中尤其值得重視。過往戲劇研究長期位處邊緣,這與戲劇此一文類所獨具的綜合藝術特質不無關係,其橫跨文學、美術、音樂、表演等領域的跨藝術特徵,導致其複雜性實際上遠超純文學的範疇。另一方面,戲劇運動的集團性和政治性,亦導致論者對於中國現代戲劇發展較為簡單化的論述,戲劇史的書寫往往與時代話語緊密連繫。不論是純粹文藝化還是政治化的角度,皆很可能遮蔽了戲劇本身一體兩面的問題,導致研究單一化和簡單化。洪深 (1894-1955)、田漢 (1898-1968)和夏衍 (1900-1995)均是中國現代重要戲劇家,同時亦長期被定位為左翼文藝陣營中的重要成員。戲劇家和政治家的身分重疊,導致他們的研究情況往往與時代的意識形態掛鈎,而目前有關他們的研究更是受到冷落,與他們的文學成就並不相稱。本文以三位劇作家為研究對象,希望通過他們的不同面向,重新審視文藝與政治之間各種複雜關係的可能性。 / 本文分為五章。第一章為導論,主要介紹本文的寫作理念、方法和背景。第二章以洪深為研究對象,重新探討他的現實主義戲劇創作和主張。洪深對改譯劇的主張和實踐,體現了他與晚清鴛鴦蝴蝶派文學和西方戲劇的深刻淵源,而他和蕭伯納之間的文學關係,反映了他對早期文明戲的戲劇改革和西方舞台的繼承,突顯了洪深如何在中西文化之間思索中國現代戲劇中的現實主義問題。第三章從西方唯美主義和先鋒文學運動的角度,重新探討田漢的創作和政治轉向。本章考察田漢對外國文學的譯介活動,當中包括英國唯美主義作家威廉.莫里斯、德國表現主義影劇、俄國和日本左翼劇場,反映了田漢戲劇運動的左翼國際主義特徵;然而田漢對日本作家佐藤春夫和谷崎潤一郎的翻譯,則體現了他對唯美主義的回歸。第四章以夏衍的戲劇創作為研究對象,重新探討夏衍的戲劇文學的獨特性。本章把夏衍此時期的劇作分為歷史劇和上海都市劇兩個角度作出分析,並將它們放在當時文學場域中與郭沫若的歷史劇、國防文學、現代派小說和左翼電影作一比較,並分析夏衍的現實主義與左翼現實主義的相異。第五章為結論,綜合前文各章的討論,重新思考三位劇作家的戲劇實踐,並重審中國現代戲劇中文藝與政治之間的複雜關係。 / There is a complicated relationship between literature and politics in modern Chinese literature, especially in modern Chinese drama. As a result, the research of modern Chinese drama has long been placed at a marginal position. Drama is an integrated artistic form consisting of literature, art, music, and performance, and therefore presents a complexity that goes far beyond "pure literature". On the other hand, the history of modern Chinese drama is closely integrated with historical discourse as a result of the organizational and political characteristics of drama movements. This shows that either literary or political point of view may confine the interpretation of their inter-related complexity and interaction. Hong Shen (1894-1955), Tian Han (1898-1968) and Xia Yan (1900-1995) are three of the most important dramatists in modern Chinese literature, who were also regarded as representative members in the left-wing literary camp. Due to their dual identities as dramatist and politician, their images are often connected with historical and ideological discourses. This has also resulted in desolation in their researches, which is not commensurate with their literary achievements. This dissertation, therefore, focuses on the three dramatists by presenting different perspectives of their works and activities, with the aim to explore the possibilities of various relations between literature and politics. / There are five chapters in the dissertation. Chapter one introduces the framework, method and background of the research. Chapter two re-examines the realistic works and theories of Hong Shen. Hong’s adaptation reflects his literary relationship with both the Mandarin Ducks and Butterflies literature and the Western drama. Moreover, Hong’s literary relationship with Bernard Shaw reflects his succession of both the tradition of the civilized drama and the Western theatre. This highlights that the characteristics of Hong Shen’s realistic theories were adapted from both China and the West. Chapter three re-explores the political transformation of Tian Han from the Western literary movements of aestheticism and the avant-garde. This chapter demonstrates the characteristics of left-wing cosmopolitanism in Tian Han’s drama movements by studying his translation activities of international literature, which include the English poet William Morris, German expressionist cinema and theatre, Russian and Japanese left-wing theatre. In the meantime, Tian Han’s translations of Japanese writers Sato Haruo and Tanizaki Junichiro reflect his return to aestheticism. Chapter four discusses the uniqueness of Xia Yan’s literary works, including his historical drama and his modern drama centering on Shanghai. This chapter emphasizes the difference of Xia Yan’s realistic style from left-wing realism by comparing Xia’s works with National Defence Literature, modernist fictions, left-wing cinema, as well as the historical drama by Guo Moruo. Chapter five concludes the significance of the dramatic transformation by Hong Shen, Tian Han and Xia Yan, and reviews the relationship between literature and politics in modern China. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / 盧敏芝. / Parallel title from added title page. / Thesis (Ph.D.) Chinese University of Hong Kong, 2015. / Includes bibliographical references (leaves 135-157). / Abstracts also in English. / Lu Minzhi.

Search for new heavy narrow resonances decaying into a dielectron pair with the CMS detector

Thomas, Laurent 07 October 2014 (has links)
Le sujet de la présente thèse porte sur la recherche de nouvelles particules très massives se désintégrant en une paire électron-positron avec le détecteur CMS.<p>Le démarrage en 2010 du Large Hadron Collider au CERN marque le début d'une nouvelle ère en physique des particules. L'énergie et l'intensité de ses faisceaux de protons, inégalées à ce jour, offre en effet la possibilité d'étudier les lois décrivant les constituants ultimes de la matière et leurs interactions à des énergies jusqu'alors inaccessibles et d'étudier des processus rares. <p>La découverte récente par les expériences ATLAS et CMS du boson scalaire prédit par la théorie de la brisure de symétrie électro-faible constitue ainsi la première percée du programme de recherche du LHC et confirme la théorie actuelle décrivant la physique subatomique, le Modèle Standard. <p>Il est cependant largement admis que cette théorie, bien que hautement prédictive et jamais mise en défaut expérimentalement jusqu'à présent, ne constitue qu'une approximation à basse énergie d'une théorie plus fondamentale. <p>Cette thèse décrit la recherche de nouvelles particules, prédites par plusieurs modèles au delà du Modèle Standard, via leur désintégration en une paire électron-positron de haute énergie. <p>La reconstruction et la sélection des électrons de haute énergie par le détecteur CMS sont des éléments centraux de cette analyse et sont étudiées en détail. Divers critères sont développés afin de distinguer les électrons des autres types d'objets physiques produits lors de collisions de protons, tels que les jets. L'intensité des faisceaux du LHC est telle que plusieurs collisions ont lieu simultanément dans le détecteur et il est montré que l'efficacité de sélection des électrons dépend fortement du nombre de ces interactions. Une technique est donc mise au point pour corriger cet effet. <p>Une méthode pour mesurer l'efficacité de la sélection directement sur les données est également développée. Celle-ci permet de confirmer les mesures obtenues à partir de simulations, jusqu'à des impulsions transverses de plusieurs centaines de GeV. <p>Le spectre de masse des paires diélectron est établi pour les données enregistrées en 2012 à une énergie dans le centre de masse des protons de 8 TeV, et un excès localisé d'événements est recherché. Aucune déviation significative par rapport au bruit de fonds attendu n'est observée et des limites très contraignantes sont établies sur le rapport de la section efficace de production d'une nouvelle résonance diélectronique et de celle mesurée au pic du boson Z. Ces résultats sont utilisés pour fixer des limites inférieures sur la masse de nouvelles particules prédites par certains modèles. <p>Le redémarrage du LHC en 2015 avec une énergie de 6.5 TeV par faisceau de proton élargira fortement le potentiel de découverte de ces résonances. En cas de découverte d'un signal, ses propriétés (telles que le spin ou l'asymétrie avant-arrière) seront étudiées avec attention. Des projections sur la précision qui pourrait alors être atteinte pour ces mesures sont donc finalement présentées en fonction de la luminosité intégrée collectée. / Doctorat en Sciences / info:eu-repo/semantics/nonPublished

La relativisation dans une perspective aréale : l'aire Caucase - Anatolie de l'Est - Iran de l'Ouest / Relative clauses in an areal perspective : The Caucasus - Eastern Anatolia - Western Iran area / Kafkas – Doğu Anadolu – Batı İran bölgesinde konuşulan dillerde sıfat işlevli yan tümceler : Bölgesel bir yaklaşım

Gandon, Ophélie 12 December 2016 (has links)
Ce travail porte sur les relatives dans les langues de l’aire Caucase – Anatolie de l’Est – Iran de l’Ouest dans une perspective aréale. Cette aire est connue pour concentrer une importante diversité génétique et typologique, avec une cinquantaine de langues appartenant à six familles distinctes : caucasique du Nord-Est, caucasique du Nord-Ouest, caucasique du Sud, turcique, indo-européenne et sémitique. Un grand nombre de ces langues sont en situation de contact et peuvent potentiellement s’influencer les unes les autres. Les relatives constituent une caractéristique intéressante à étudier dans une telle perspective car les constructions ayant fonction de relative peuvent varier selon nombreux paramètres d’une langue à l’autre ou au sein d’une même langue (position de la relative, finitude du verbe, etc.) ; chaque valeur possible pour un paramètre donné étant un trait pouvant potentiellement se diffuser. La première partie de cette thèse consiste en une description détaillée des stratégies de relativisation des langues de l’aire. Diverses stratégies sont identifiées, dont certaines couramment mentionnées dans la littérature, mais d’autres également plus atypiques du point de vue typologique. La deuxième partie consiste en une analyse des données décrites dans la première partie : après avoir identifié de manière précise les paramètres de variation et leurs différentes valeurs possibles parmi les stratégies disponibles de l’aire (environ 40 paramètres, 80 sous-paramètres et plus de 200 valeurs possibles), plusieurs zones géographiques sont mises en évidence où une même stratégie ou une même valeur pour un paramètre donné sont partagées par des langues non nécessairement apparentées génétiquement. Pour plusieurs de ces zones, il semble s’agir d’un phénomène de convergence, étant donné que les langues concernées divergent de leurs familles génétiques respectives et/ou le trait ou la stratégie partagé(e) est atypique. Pour finir, plusieurs facteurs pouvant intervenir dans la diffusion ou non d’une stratégie ou d’un trait linguistique sont suggérés. / This work deals with relative clauses in an areal perspective, focusing on languages of Caucasus – Eastern Anatolia – Western Iran area. This area is known to display an important linguistic diversity (genetic as well as typological) with about fifty languages belonging to six distinct families: North-East Caucasian, North-West Caucasian, South-Caucasian, Turkic, Indo-European and Semitic. Most of these languages are in contact and may influence each other. Besides, relative clauses constitute an interesting field to investigate in an areal perspective, given that the constructions used as relative clauses may vary according to numerous parameters, crosslinguistically or within the same language (e.g., position of the relative clause, finiteness of the verbal form, etc.); each value for a given parameter is a feature that may possibly diffuse across languages.The first part of this work is a fine-grained description of the relativization strategies available in the area. Various strategies are identified. The area displays all strategies commonly mentioned in the literature, as well as some typologically less common strategies.The second part of the work is an analysis of the data. After identifying all variation parameters and their different values in the strategies available in the area (i.e., about 40 main variation parameters, 80 sub-parameters and more than 200 potential values), several geographical areas are highlighted where the same strategy or the same value for a given parameter is shared by languages that are not necessarily genetically related. For some of these areas, it seems that a convergence phenomena is involved given that languages may diverge with this respect from their respective genealogical families and/or the shared feature or strategy is typologically uncommon. Finally, some factors that could be involved in the occurrence or not of a language-contact induced change are suggested. / Bu tezde bölgesel bir açıdan Kafkas – Doğu Anadolu – Batı İran bölgesinde konuşulan dillerde sıfat işlevli yan tümceler inceleniyor. Hem genetik hem de tipolojik olarak dilsel zenginliği ile tanınan bu bölgede günümüzde altı farklı aileden (Kuzeydoğu Kafkas dilleri, Kuzeybatı Kafkas dilleri, Güney Kafkas dilleri, Türk dilleri, Hint-Avrupa dilleri, Sami dilleri) elliyi aşkın dil konuşulmaktadır. Bu dillerin çoğu birbirleri ile temas halindeler ve birbilerini etkileyebiliyorlar. Bu bakımdan, sıfat işlevli yan tümce olarak kullanılan yapıların diller arasında, hatta aynı dil içinde dahi birçok parametreye göre çeşitlilik gösterdiğini (örneğin yan tümcenin nitelediği ada göre konumu, yan tümcedeki fiil şekli (tam donanımlı ya da sıfat-fiil oluşu), vb.), ve bu parametrelerin alabileceği değerlerin bir dilden diğerine yayılabilen bir nitelikte olduğunu göz önüne alırsak, sıfat işlevli yan tümcelerin bölgesel ve karşılaştırmalı bir açıdan ele alınabilecek zengin bir çalışma konusu olduğu belirgin hale gelmektedir. Tezin ilk kısmında, adı geçen bölgede konuşulan dillerdeki sıfat işlevli yan tümce yapıları ayrıntılı bir şekilde belgeleniyor. Bu belgeleme literatürde sıkça bahsi geçen alışılmış yapıların yanı sıra çok bilinmeyen, atipik yapıları da gün yüzüne çıkarıyor.Tezin ikinci kısmında ise birinci kısımda belgelenen veriler çözümleniyor. Sıfat işlevli yan tümcelere ait tüm parametreleri ve bu parametrelerin alabileceği farklı değerleri (toplamda yaklaşık 40 ana parametre, 80 alt-parametre ve 200’den fazla olası değer) saptadıktan sonra, aynı yapıyı ya da belli bir parametreye ait aynı değeri kullanan fakat genetik açıdan birbiri ile ilişkisi olmayan dillerin oluşturduğu birtakım coğrafi alan tespit ediliyor. Bu alanların bazısında saptanan diller, kullandıkları sıfat işlevli yan tümce yapıları veya bu yapılardaki bazı parametrelerin aldığı değerler bakımından genetik olarak ilişkili oldukları dillerden farklılık gösterdiklerinden ve/veya kullandıkları yapıların tipolojik olarak alışılmış olmadıklarından dolayı, bu belirtilen alanlarda bir yöneşme (convergence) meydana gelme olasılığı yüksektir. Son olarak da bir yapının ya da belli bir parametre değerinin yayılıp yayılmamasına sebep olabilecek bir kaç etken öneriliyor.
