La rose est la fleur la plus vendue au monde. Elle a une place prépondérante en horticulture et dans l'industrie des parfums, c'est pourquoi des études visant à préciser les mécanismes cellulaires d'émission du parfum ont été entreprises. Des travaux antérieurs ont permis d'émettre une hypothèse selon laquelle le parfum serait véhiculé par des vésicules lipidiques. Nos observations ont montré que dans les pétales de roses, les vésicules sont composées d'une matrice centrale où se concentrent les triglycérides entourés d'une membrane à un seul feuillet phospholipidique. Ces caractéristiques étayent la théorie selon laquelle les vésicules lipidiques purifiées de pétales de rose sont des oléosomes. Cependant, l'oléosine, protéine marqueur de ce compartiment, n'a pas été identifiée. Ces vésicules sembleraient être impliquées dans le stockage des enzymes des voies de biosynthèse des parfums et des parfums eux-mêmes. Le gène RhPAAS, impliqué dans la voie de biosynthèse du 2-phényléthanol, a également été étudié. Des travaux préliminaires montrent que le QTL majeur expliquant la présence de 2-phényléthanol chez Rosa wichuraiana et le gène RhPAAS sont localisés sur le même locus dans le groupe de liaison B7. La modulation de l'expression du gène RhPAAS a donc été une hypothèse pour expliquer la présence ou l'absence de 2-phényléthanol dans la population HW. Au stade BJO, seuls les descendants produisant beaucoup de 2-phényIéthanoI, expriment RhPAAS. Le transcrit est accumulé au stade BJO dans les pétales c'est-à-dire avant le maximum d'émission du parfum. L'allèle a1 lié à la production du 2-phényléthanol a été identifié tandis qu'un autre allèle a2 s'exprime uniquement chez les roses produisant très peu de 2-phényléthanol

Il existe différentes techniques de manipulation et de détection de molécules uniques. Parmi elles, la mesure du courant ionique traversant un pore nanométrique unique est la plus ancienne. Le travail effectué dans cette thèse utilise cette technique et s'articule autour de deux objectifs. Tout d'abord, l'utilisation d'un nanopore unique obtenu par attaque de trace permet d'imiter les expériences déjà faites dans la littérature avec d'autres types de pores. Certains phénomènes, tels que la rectification par exemple, ont pu être observés, mais d'autres comme la translocation n'ont pu l'être. Ensuite, une étude du bruit de conductance électrique démontre l'existence d'un phénomène qui n'avait jusqu'alors pas été soulevé dans la littérature. En effet, ce bruit ne peut pas être imputé aux fluctuations des caractéristiques de la géométrie du pore ou de sa paroi, mais plutôt à des effets coopératifs sur la mobilité des ions dans un milieu confiné.

Since the 1936 publication of Gone with the Wind and the 1939 release of David O. Selznick’s film version of the book, the city of Atlanta has been associated in the public mind with Margaret Mitchell’s tale of the Old South, the Civil War and Reconstruction. The work of Mitchell and Selznick created images that shaped the public’s understanding of southern history and of Atlanta’s identity. This dissertation examines a series of attempts to capitalize on the fame and popularity of Gone with the Wind in museums in the Atlanta area. Focusing on the interpretive efforts of three entities—the Atlanta History Center, Clayton County, and the Margaret Mitchell House, Inc.—this study reveals the problematic nature of Mitchell’s and Selznick’s work and the impact that the book and film have had on shaping Atlanta’s identity and the public memory of the South.

The subject of this study was to investigate the species composition and spatial distribution pastern of iving (Rose Bengal stained) benthic foraminifera in sediment surface samples (0-1 cm) off the Southwestern Taiwan and Dongsha Atoll. The main objectives of this study was to document the living benthic foraminiferal assemblages off the Southwestern Taiwan and Dongsha Atoll and to examine their distribution in relation to environmental parameters. Four benthic foraminiferal biofacies were recognized within the substrate type in Dongsha Atoll: A1 (Fine-grained) is represented by Pseudomassilina spp. - Quinqueloculina parkeri, A2 (Fine-grained) is represented by Hauerina spp. - Pseudomassilina spp., B1 (Coarse-grained) is characterised by Calcarina spp. - Quinqueloculina spp., B2 (Coarse-grained) is characterised by Amphistegina spp. - Quinqueloculina spp. Sediment surface samples off the Southwestern Taiwan during May 2009 led to the identification of four assemblages. Assemblage A is characterised by Ammonia spp. - Bolivina spp., Assemblage B between is characterized by Asterorotalia spp. - Globobulimina spp., Assemblage C is represented by Cibicides spp. - Nummulites spp., Assemblage D is represented by Ammonia spp. - Cibicides spp. Sediment surface samples off the Southwestern Taiwan during Nov. 2009 led to the identification of three assemblages. Assemblage A is dominated by Ammonia spp. - Cibicides spp., Assemblage B is characterised by Ammonia spp. - Bolivina spp., Assemblage C is characterised by Asterorotalia spp. - Bolivina spp. Stained benthic foraminifera form Dongsha Atoll correlated with current wave, collected site, coarse fraction and TOC contents. Living benthic foraminifera off the Southwestern Taiwan seems not to be related with TOC contents and coarse fraction, the assemblages were found to be more related to tidal energy and lateral transport.

The objective of this thesis is to explain the dynamics bringing about the removal of the Georgian President Eduard Shevardnadze from power through the &lsquo / Rose Revolution&rsquo / . Relying on an historical sociological approach, contrary to the society-centered and the state-centered studies in the literature on the &lsquo / Rose Revolution&rsquo / , this thesis argues that the coercive, administrative, extractive, distributive and regulative incapacitation of the Georgian state, which resulted in the loss of state autonomy vis-&agrave / -vis domestic and external political actors before the &lsquo / Rose Revolution&rsquo / , led to the removal of Shevardnadze. In fact, the society-centered studies, which exclusively focus exclusively on the political opposition, the NGOs and the mass media, fail to explain the dynamics of the &lsquo / Rose Revolution&rsquo / since they neglect the role of the state. Likewise, the state-centered studies&rsquo / exclusive focus on the coercive aspect of the Georgian state capacity resulted in the insufficient explanation of the &lsquo / Rose Revolution&rsquo / since they neglect other aspects of state capacity such as administrative, extractive, distributive and regulative. The thesis consists of six main chapters, introduction and conclusion. Chapter 2 develops the theoretical framework of the study. Chapter 3 explores the historical background. Chapter 4 examines the process leading up to the &lsquo / Rose Revolution&rsquo / . Chapter 5 and 6 analyze the &lsquo / Rose Revolution&rsquo / and its aftermath. Before the concluding chapter, Chapter 7 compares the Georgian case with the other seven post-Soviet cases.

ABSTRACT While in the developed countries, flowers are living necessity and enjoy a sizable market, the Council of Agriculture Executive Yuan R.O.C points out that cultivation and sales of flowers are important items in the prospecting dedicated agriculture industries of Taiwan. Besides the enjoyment and appreciation the beauty of blooming by oneself , in social life flowers can perform the instrumental function of expressing wishes in the occasion of marriage, birthday, promotion, house moving, and consolation in the sickness or sadness. The study of flower preference schemata is one of the importance concepts for flower product design and development. The current research figured out different patterns of flower preference among people¡¦s mind ,through pictures of moth orchid and rose designed by the three factors of flower beauty: color, volume, and package. The distinctive flower buying behaviors of the different groups were studied consequently. In our valid sample are 696 teachers from senior high and junior high schools and elementary schools in the Kaohsiung area in Taiwan. In addition to the description and analysis on people¡¦s flower buying behavior about flower type preference, shop choice, purchase frequency, and flower-as-present purchase behavior, the major findings of the current research are as the following: (1) Confirming that there exist distinctive flower preference schemata in people mind; (2) Flower preference affect the purchase behavior; (3) Demographic variables moderate the effect of flower preference on the purchase behavior; (4) Flower attitude and demographic variables affect flower consumption behavior.

Lietuvoje dekoratyviųjų želdinių poreikio augimas stebimas kasmet. Kartu su augančia rinka daugėja ir įmonių užsiimančių sodinukų prekyba. Deja, jų auginimas Lietuvoje yra kur kas mažiau populiarus. Nežiūrint to, kad pirkėjas dažnai mieliau renkasi vietoje išaugintus sodmenis, dauguma medelynų negali pasiūlyti pakankamos augalų įvairovės. Tokia situacija susidaro dėl gana sudėtingų aplinkybių, susiformuojančių šiame versle. Viena priežasčių yra augalų įšaknydijimui gana nepalankios klimato sąlygos ir brangūs augimo reguliatoriai. Šio darbo tikslas: įvertinti augimo reguliatoriaus „POKON“ poveikį erškėtinių, sausmedinių ir raugerškinių šeimų augalų žaliųjų auginių įsišaknidijimui. Tikslui pasiekti buvo suformuoti tokie uždaviniai: išanalizuoti medelynų veiklą, apibendrinti augalų šaknijimąsi lemiančius veiksnius bei įvertinti augimo reguliatoriaus „POKON“ veiksmingumą pasirinktų augalų šeimų žaliųjų auginių rizogenezei. Eksperimentai buvo atlikti Kaišiadorių rajone, Kalniškių kaime per laikotarpį nuo 2010 birželio 17 dienos iki 2010 rugpjūčio 17 dienos. Vertinant auginių įsišaknijimo potencialą, buvo skaičiuojamas auginių įsišaknijimo procentas, išaugusių šaknų bei naujų ūglių skaičius. Apibendrinus tyrimo rezultatus, padarytos tokios išvados: 1. Bakalauro darbe atliktais eksperimentais parodyta, kad augimo reguliatorius „POKON“ gali būti naudojamos augalų rizogenezei inicijuoti. 2. Nustatytas teigimas „POKON“ poveikis šaknų augimui žaliaisiais auginiais dauginant...

Unfortunately, their production in Lithuania is much less popular in spite of the fact that buyers often prefer to shop locally harvested saplings, most nurseries can not offer a sufficient variety of plants. This situation arises for quite difficult circumstances in this business. One of the reason is that plant roots are growing bad in this climatic conditions, plus expensive growing regulators. The point of this work is: to evaluate the growing regulator „POKON“ impact for rose, honeysuckles and barberry families for green cuttings of plants. In order to achieve the following objectives were set to analyze: the nursery operations, plant roots growing summarize and assess the determinants of „POKON“ the effectiveness for selected plant families. The experiments were carried out at Kaišiadorys district, Kalniškės village during the period from 2010 June 17 until 2010 August 17. The assessment of the cuttings roots potential, was calculated by the percentage increase in the roots and new shoots. Summarizing the results, was made following conclusions: 1. Undergraduate work performed experiments showed that the growing regulator „POKON“ can be used to initiate plant rhizogenesis. 2. Set assertion of „POKON“ for root cuttings by multiplying the sturgeon, honeysuckles and barberry families of plants. 3... [to full text]

The presence of flowers is felt in Catholic architecture, literature, artwork, personal histories and devotional practices. This, however, has not always been the case. The Catholic Church has had a long and tumultuous relationship with flowers, the focus of which has been the subject of considerable scholarship (e.g. Fisher (2011, 2007), Ward (1999), Winston-Allen (1997), Goody (1993), Coats (1970)). What has not been much considered is a phenomenological treatment of Catholic floral experience, and how such experiences have shaped individual and shared understandings of the Catholic faith. This thesis seeks to redress this omission through an exploration of the life of the Polish Catholic mystic, St. Faustina Kowalska (1905-1938), whose mystical experiences with the divine were explicitly mediated and narrated through flowers. Through Faustina’s diary, Divine Mercy in my Soul, we gain access to powerful, and unequivocally Catholic, experiences with flowers which comprise the very centre of her religious convictions. This thesis queries the ways in which flowers have dynamically shaped, and have been shaped by, St. Faustina's relationship with God and Catholic holy figures. To address this question I use the semiotic, phenomenological and hermeneutic approach of Max van Manen. Van Manen uses four elements of lived experience he calls lifeworld existentials, these are: lived space, lived time, lived body and lived relationality. These four categories are applied to St. Faustina’s life as she engages with God spatially, temporally, corporeally and relationally; each reveals the centrality of flowers in her religious experiences. While this thesis focuses on the religio-floral experiences of a particular mystic-saint, its significance lies also in the broader Catholic narrative of which it is a part. Writing about flowers was a transformative medium in Faustina's life and has been historically significant in the lives of many other Catholic saints and mystics who recorded similar experiences. This thesis, in describing the details of St. Faustina’s floral-saturated experiences from her diary, reveals a particularized instance of a paradigmatic Catholic phenomenon whereby flowers provide access to the sacred.
