Texto completoResumen
Les aptitudes de Cichorium intybus L. Var. Magdebourg en culture in vitro ont été contrôlées. A partir de racines tubérisées matures ainsi que de feuilles cotylédonnaires issues de germination, il est possible d'obtenir une callogenèse importante, d'installer des suspensions cellulaires et d'induire la formation de bourgeons. En exploitant la variabilité induite par la culture in vitro, deux souches de cals résistantes au glyphosate et une souche résistante au glufosinate ont été isolées. Comparées aux souches sensibles, elles prolifèrent respectivement sur des doses 25 et 7,5 fois plus élevées. Il a été montré que les souches résistantes au glyphosate ont une activité EPSP synthase plus élevée que les souches sensibles (4,4 et 4 fois) alors que l'enzyme est inhibée de la même manière par l'herbicide. Ceci laisserait supposer l'existence d'un mécanisme d'amplification génique. A partir de ces souches, des plantes ont été obtenues mais après acclimatation en serre une seule souche s'est montré viable. Du cal a été initié à partir de ces plantes. Les tests in vitro ont montré que la résistance est conservée partiellement (18 fois) et que l'activité enzymatique a légèrement diminué (3,3 fois). Ces plantes sont totalement autoincompatibles, mais par croisement avec des plantes sensibles des graines ont été obtenues. Les traitements en serre effectués sur des jeunes plantules ont montré que toutes les plantes F1 sont sensibles au glyphosate. Les tests in vitro ont confirmé ces résultats. L'activité enzymatique des plantes F1 in vivo et in vitro est comparable à celles des plantes sensibles. Deux hypothèses sont envisageables, il s'agit soit d'un caractère récessif soit d'un variant épigénique

Texto completoResumen
La Flore bactérienne isolée de pourritures sur endives au forçage a été caractérisée. L'investigation a porté sur des symptômes typiques connus et sur des symptômes nouvellement étudiés (sur racines et sur chicons). Les isolats s'apparentent surtout à Erwinia carotovora variété atroseptica. Ils forment un groupe homogène sur le plan biochimique et hérérogène par leurs caractéristiques sérologiques. Des méthodes d'évaluation du pouvoir pathogène des souches bactériennes isolées ont été testées sur plantes entières en cours de forçage et sur organes isolés ; l'incidence du stade de développement de la plante, du niveau d'inoculum et du mode d'inoculation sont étudiés. Le cycle de la bactérie a été abordé par l'étude de la pénétration d'un inoculum à E. C. A. Spontané et artificiel ; l'inoculation des souches durant la phase de végétation de C. Intybus n'aboutit pas à l'expression de la bactériose. Les inoculations en cours de forçage donnent des résultats très variables et surtout dépendants de la température. L'observation de la bactériose dans la plupart des lots témoins expérimentaux permet de conclure à la présence potentielle d'Erwinia dans toutes les racines au forçage : la bactériose à Erwinia est une maladie opportuniste. L'utilisation d'un agent chimique (sulfate de cuivre sous forme de bouillie bordelaise), pouvant modifier qualitativement et quantitativement la flore bactérienne, semble indiquer une possibilité de pénétration d'E. C. A. Au stade végétatif et permet de montrer la présence d'un potentiel infectieux important au niveau des bases foliaires résiduelles après récolte ce potentiel étant responsable de la pourriture ultérieure pendant le forçage. L'étude de quelques facteurs agro-climatiques sur l'expression de la maladie montre que le passé agronomique de la racine (notamment de la fumure azotée au champ) est corrélé positivement à la mortalité des chicons, et que les conditions de conservation des racines ainsi que la température de forçage sont déterminantes pour l'expression de la maladieThe bacterial flora isolated from chicory rot during forcing was characterized. Typical well-known symptoms as well as atypical symptoms encountered during present studies, were investigated on roots and chicons. Isolates were mainly related to Erwinia carotovora subsp. Atroseptica. They formed an homogeneous group from a biochemical point of view and an heterogeneous one with respect to their serological characteristics. Methods for assessing pathogenicity of the isolated bacterial strains were tested on whole plants during forcing and also on isolated organs in order to deter m ne the effect of the physiological stage of plants, of inoculum level and of modes of inoculation. The life cycle of bacteria was investigated by studying the penetration in plant tissues of spontaneous and artificial E. C. A. Inocula; the inoculation of strains during the vegetative growth of C. Intybus did not lead to expression of bacteriosis. Inoculations during forcing produced much variable results which were especially dependent on temperature. Observations of bacteriosis in most of the experimental control lots suggest that Erwinia was potentially present in all roots during forcing: this bacteriosis is an opportunistic disease. The use of a chemical (copper sulphate in the form of Bordeaux mixture) able to modify the bacterial flora both qualitatively and quantitatively, indicated that E. C. A. Could possibly penetrate into plants during vegetative growth. It also demonstrated the presence of bacterial infection in leaf residues (left after harvesting of roots) which accounts for subsequent rot during forcing. The study of the influence of some agro-climatic factors on disease expression showed that previous growing conditions of roots (nitrogen fertilization in the field) were positively correlated to chicon mortality, and that the disease expression was highly dependent on the conditions of root storage and forcing temperature

Texto completoResumen
As a Kentuckian, the past has always seemed to maintain a complex relationship with the present. Subdivisions spread across what were once tobacco fields and plantation estates; Appalachian folkways have long been slowly disappearing due to technological change, outmigration, and environmental degradation. In the poetry collection “pretty sad endings,” I try to ask— as our physical and cultural landscape changes, what are we losing, and what do we gain? And what remains (however transformed)? I use surrealism throughout the manuscript to elevate aspects of contemporary suburbia, Americana, relationships, and popular culture to the level of the mythical and spiritual. By distorting the everyday, I hope to tease out some of the real wonder that might be waiting in unexpected places, such as a cul-de-sac, a freeway billboard, or a drugstore parking lot. In these poems, I also try to create spaces where humor and emotional sincerity can coexist, while maintaining a raw curiosity in the strangeness and power of words themselves. My hope is not just that this collection can communicate some of the joys and hardships and eccentricities of my home, but that it can also speak relevantly about contemporary American life and relationships to readers anywhere.

Texto completoResumen
Des protoplastes foliaires issus de jeunes plantes cultivées « in vitro » de Cichorium intybus L. Var. Witloof ou « zoom » se divisent de façon satisfaisante dans un milieu liquide comportant : des éléments minéraux, des vitamines, du saccharose, de la glutamine, du mannitol et des substances de croissance (ANA et BAP). Les microcals formés après 7 jours de culture poursuivent leur prolifération sur un milieu gélosé de composition identique mais de pression osmotique réduite. A partir des cals d'une taille supérieure à 2 mm, il est possible d'initier des bourgeons après modification des milieux de culture utilisés en phase initiale : remplacement de la glutamine par de l'azote minéral, réduction des concentrations hormonales et suppression du mannitol. Les bougeons formés s'allongent et s'enracinent sur un milieu nutritif gélosé dépourvu d'hormones, réparti dans des flacons favorisant les échanges gazeux. Le transfert des plantes en serre est possible 4 à 5 mois après la mise en culture des protoplastes, leur culture dans des conditions favorables à la floraison permet d’obtenir des inflorescences apparemment normales. Le forçage des racines produit des endives présentant toutes les caractéristiques du cultivar « zoom ». Le fait de disposer d’un moyen de produire des plantes à partir de protoplastes est intéressant. Toutefois l’utilisation des protoplastes pour la multiplication ou l’amélioration de la chicorée ne pourrait être effective que le jour où les rendements des plantes seront améliorés.

Texto completoResumen
Les influences de la lumière, de l'obscurité et de l'ANA sur les peroxydases apoplastiques et sur le développement d'explants racinaires de chicoree (Cichorium intybus L. ) ont été analysées. Les activités auxine-oxydasiques dûes aux peroxydases sont toujours plus fortes à l'obscurité qu'à la lumière. L'utilisation de syringaldazine, co-substrat spécifique des peroxydases impliquées dans le processus de lignification, a montré une corrélation positive entre synthèse de lignine et activité syringaldazine-oxidase. La prolifération cellulaire des explants (callogenèse) est d'autant plus importante que la lumière ou l'acide l-naphtanlène acétique (ANA) diminuent l'activité auxine-oxydasique. La baisse sensible d'activité syringaldazine-oxydase provoquée par l'ANA conduit à la non édification de la couche cellulaire périphérique lignifiée. Cette dernière est bien représentée chez les explants cultivés à la lumière et sans ANA. Ce régulateur de croissance perturbe aussi fortement le développement des explants, avec perte de leur potentialité organogène. L'hypothèse d'une relation entre phénomène de cicatrisation précoce, lié à la couche lignifiée, et capacité organogène des explants a été formulée. L'ANA induit l'expression d'une isoperoxydase basique, la Cicpx (Cichorium intybus cationic peroxydase). Celle-ci, également rencontrée dans les milieux de culture des suspensions cellulaire de chicorée cultivées en présence d'ANA, a été purifiée. Le taux de purification important (RZ = 3,5) a permis de déterminer son point isoélectrique de 8,9, son poids moléculaire de 34 KDa et son absence de réactivité envers la syringaldazine. Son séquençage partiel a abouti à quatre séquences de polypeptides dont deux présentent une certaine homologie avec d'autres peroxydases végétales. Ces dernières ont servi à l'élaboration de deux amorces pour essayer d'amplifier par PCR un fragment du gène de la Cicpx. Le but étant de se servir de ce fragment comme sonde nucléotidique, afin de déterminer si la Cicpx est une isoforme ou une isoenzyme. Mais, la présence de certains acides aminés ont conduit à des amorces dites dégénérées qui ne nous ont pas permis d'aboutir à nos fins. Cependant, un ADNc de peroxydase a été obtenu par RT-PCR, dont la correspondance avec la Cicpx reste à démontrer.

Texto completoResumen
Notre etude a ete entreprise sur 3 cybrides de chicoree male steriles 411, 523 et 524. Ces cybrides sont issus de fusions entre des protoplastes de chicoree industrielle fertile et des protoplastes de tournesol male sterile presentant la sterilite male cytoplasmique pet1, induite par la sequence orf522, situee en aval du gene atpa. Ces cybrides ont ete choisis dans le but de transferer les cytoplasmes inducteurs de sterilite d'un contexte nucleaire chicoree industrielle a un contexte nucleaire chicoree endive. Apres cinq generations de retrocroisements, les morphologies florales, variables au depart, se sont stabilisees mais differemment en fonction du pollinisateur utilise. Un des noyau, jupiter, restaure la fertilite male des trois cybrides. Les genomes mitochondriaux instables au depart, se sont presque totalement stabilises independamment du contexte nucleaire, ils sont differents les uns des autres, conservent des fragments specifiques de la chicoree fertile et du tournesol male sterile et presentent des fragments nouveaux issus de rearrangements. Le cybride 524 n'a pas integre la sequence orf522 du tournesol, par contre, les cybrides 411 et 523 l'ont integree mais sans le gene atpa du tournesol, permettant, chez ces derniers, son expression grace a une contrascription. La region 5 de l'orf522 a subi des remaniements par rapport au tournesol. L'analyse rflp montre des profils de restriction identiques pour la sequence orf522 chez les cybrides 411 et 523. Pourtant, les experiences de rt-pcr montrent une expression differente de l'orf522 pour ces deux cybrides.

Texto completoResumen
La commercialisation de l’endive en 4ème gamme est limitée par le rougissement rapide des feuilles après la découpe. Ce travail propose une approche alternative pour prolonger la durée de conservation de l’endive en 4ème gamme inhibant ou tardant le rougissement des coupes : l’application d’un choc thermique à 46°C pendant 120 sec. L’effet du choc thermique sur l’activité des enzymes impliqués dans le processus du brunissement enzymatique et sur l’accumulation des composés phénoliques a été analysé. L’expression des gènes impliqués PAL1, PAL2, PPO et Hsp90 a été réalisée en suivant de l’accumulation des ARNm par PCR quantitative en temps réel. Ces travaux ont montré que le choc thermique induit une surexpression des Hsp90 et inhibe l’activité de la PAL, de la PPO, l’accumulation des composés phénoliques et l’expression des gènes de la PAL1 ce qui a par conséquence l’inhibition du rougissement pendant 8 jours à 4°C. L’atmosphère contrôlée (4%O2 + 5% CO2) n’est pas suffisante pour inhiber le rougissement. L’application d’inhibiteurs de la synthèse (AVG) et de l’action de l’éthylène (1-MCP) a montré que l’éthylène n’est pas impliqué dans l’inhibition de la synthèse de la PAL en réponse au choc thermiqueMarketing possibilities for fresh-cut endive are limited by the rapid red discoloration of the leaves after cutting. This work proposes an alternative approach to prolong the shelf life of fresh-cut endive by inhibiting or delaying the red discoloration of pieces: the application of a heat shock at 46°C for 120 sec. The effect of heat shock on the activity of enzymes involved in the process of enzymatic browning and the accumulation of phenolic compounds were analyzed. The expression of genes involved PAL1, PAL2, PPO and Hsp90 was performed by following the accumulation of mRNA by real-time quantitative PCR. This work has shown that heat shock induces overexpression of Hsp90 and inhibits the activity of PAL, PPO, the accumulation of phenolic compounds and gene expression of PAL1 which consequently inhibition of discoloration for 8 days at 4°C. The controlled atmosphere (4%O2 + 5%CO2) is not sufficient to inhibit the red discoloration. The application of inhibitors of synthesis (AVG) and action of ethylene (1-MCP) has shown that ethylene is not involved in the inhibition of the synthesis of PAL in response to heat shock

This paper aims to explore gender differences in reactions to romantic relationship dissolutions. Within the body of research on relationship breakups, attachment theory is frequently mentioned. Empirical data on adult attachment styles and how they relate to gender differences and reactions to separations will also be explored. The issue of gender is prevalent in psychological literature. Such classification regarding reactions to relationship breakups is ambiguous and research should turn to individuals and relationships when exploring breakups.

Smith, Jennifer. "Theorizing Digital Narrative: Beginnings, Endings, and Authorship". VCU Scholars Compass, 2012. http://scholarscompass.vcu.edu/etd/316.
Texto completoResumen
Since its development, critics of electronic literature have touted all that is “new” about the field, commenting on how these works make revolutionary use of non-linear structure, hyperlinks, and user interaction. Scholars of digital narrative have most often focused their critiques within the paradigms of either the text-centric structuralist model of narrativity or post-structuralist models that implicate the text as fundamentally fluid and dependent upon its reader for meaning. But neither of these approaches can account completely for the unique modes in which digital narratives prompt readerly progression, yet still exist as independent creative artifacts marked by purposive design. I argue that, in both practice and theory, we must approach digital-born narratives as belonging to a third, hybrid paradigm. In contrast to standard critical approaches, I interrogate the presumed “newness” of digital narratives to reveal many aspects of these works that hearken to print predecessors and thus confirm classical narratological theories of structure and authorship. Simultaneously, though, I demonstrate that narrative theory must be revised and expanded to account for some of the innovative techniques inherent to digital-born narrative. Across media formats, theories of narrative beginnings, endings, and authorship contribute to understanding of readerly progress and comprehension. My analysis of Leishman’s electronically animated work Deviant: The Possession of Christian Shaw shows how digital narratives extend theories of narrative beginnings, confirming theoretical suitability of existing rules of notice, expectations for mouseover actions, and the role of institutional and authorial antetexts. My close study of Jackson’s hypertext my body: a Wunderkammer likewise informs scholarship on narrative endings, as my body does not provide a neatly linear plot, and thus does not cleanly correspond to theories of endings that revolve around conceptions of instabilities or tensions. Yet I argue that there is still compelling reason to read for narrative closure, and thus narrative coherence, within this and other digital works. Finally, my inquiry into Pullinger and Joseph’s collaboratively written Flight Paths: A Networked Novel firmly justifies the theory of implied authorship in both print and digital environments and confirms the suitability of this construct to a range of texts.

MacDowell, James. "The final couple : happy endings in Hollywood cinema". Thesis, University of Warwick, 2011. http://wrap.warwick.ac.uk/49034/.
Texto completoResumen
This thesis concerns a very common, yet surprisingly under-examined, concept: the Hollywood ‘happy ending’. Focusing on an aspect of this convention that I call the ‘final couple’ (i.e.: an ultimate romantic union), the study examines movies from throughout the history of popular American cinema in order to interrogate common critical assumptions about ‘happy endings’. Chapter 1 questions the existence of the homogenous norm the ‘happy ending’ by attempting to define it – a task more challenging than the convention’s reputation would have us believe. Chapter 2 looks at the relationship between ‘happy endings’ and closure, arguing that, while some films succeed in making their final couples feel emphatically ‘closed’, others use different strategies to render the same convention comparatively ‘open’. Chapter 3 examines the connection between ‘happy endings’ and ‘unrealism’, considering firstly the traditionally close conceptual relationship between the ‘happy ending’ and fiction tout court, before, secondly, exploring the ways in which the final couple relates to debates concerning the ‘openness’ of life and the ‘closed’ nature of narrative. Chapter 4 addresses the ideology of ‘happy endings’ by discussing (1) what potential the concept of the final couple might be said to have for structuring viewers’ real-life romantic relationships, (2) the ideological implications of closure, and (3) the different ideological meanings that a final couple can convey in what is often taken to be an innately ‘conservative’ genre, the romantic comedy. The results of my analyses suggest that ‘happy endings’ are as conducive to variation as any other artistic convention – a fact that has significant ramifications for our thinking about Hollywood conclusions.

Watson, Sonia. "Glutamate pharmacology of mammalian primary mechanosensory nerve endings". Thesis, University of Aberdeen, 2015. http://digitool.abdn.ac.uk:80/webclient/DeliveryManager?pid=225803.
Texto completoResumen
The system involved in mechanotransduction by proprioceptive sensory organs, such as muscle spindles, is poorly understood. We previously reported that stretch releases glutamate from synaptic-like vesicles (SLVs) within muscle spindle terminals (the proprioceptive sensory organs of muscles), and activates a non-canonical mGluR, modulating afferent firing (Bewick et al, 2005). If, as our previous data and the literature suggests, this system is present in other mechanosensory endings, such as baroreceptors, it presents a drugable target in the treatment of hypertension. With current hypertension therapy ineffective in around 20% of patients a novel target such as this is highly important to investigate. This study aimed to further investigate this receptor's pharmacology by screening ligands selective for classical mGluRs for their ability to alter stretch-evoked spindle firing in muscle spindles and SLV uptake in lanceolate endings. I found that although there are differences between the two systems, overall the pharmacology most closely matches that of the currently unsequenced phospholipase D coupled mGluR previously studied in the hippocampus (Pellegrini-Giampietro et al., 1996). Furthermore the pharmacology does not match that of any canonical mGluR (or iGluR). This pharmacological profiling allowed the development of novel kainate-derived compounds which were tested to find more potent analogues suitable for “click chemistry” (Kolb et al, 2001). The development of these compounds allowed further compounds to be synthesised with biotin and fluorescent side chains which will be used in further studies ultimately to allow sequencing of the receptor. In respect to baroreceptors I expanded our data in the working-heart-brainstem model and developed an isolated aortic preparation which will be used in further studies to further characterise this SLV/glutamate system in baroreceptors.

Texto completoResumen
Le brunissement enzymatique de la scarole (variete geante maraichere) a ete etudie sur les feuilles chlorophyliennes et etiolees en considerant des parametres biochimiques intervenant dans cette alteration: les composes phenoliques et les enzymes d'oxydation. Les derives hydroxycinnamiques sont identifies grace a une methode originale d'hydrolyse enzymatique par l'hydroxycinnamoylquinate esterase. Ce sont des derives tartriques, shikimiques et glycosyle de l'acide cafeique. Deux derives du kaempferol et un derive de la quercetine sont identifies. Parmi ces composes phenoliques, l'acide dicafeoyltartrique constitue l'orthodiphenol majeur des feuilles de scarole. Les conditions de purification de l'activite polyphenoloxydasique sont determinees. Deux entites ppo1 et ppo2 sont separees et caracterisees. Une activite ppo3 associee a une activite peroxydasique a ete etudiee. Des etudes cinetiques montrent une forte affinite de ppo1 et ppo2 vis-a-vis de l'acide cafeique et de ses esters. La sensibilite au brunissement est limitee par la teneur en phenols, en particulier en acide dicafeoyltartrique. Alors que l'oxydation des esters cafeiques semble due a l'activite polyphenoloxydasique, celle de flavonols resulterait d'une degradation sous l'action de la peroxydase, susceptible d'intervenir dans le brunissement des feuilles de scarole. Les tissus chlorophylliens presentent des activites ppo et pod plus faibles que les tissus etioles mais des teneurs en phenols plus elevees. L'exposition a la lumiere des tissus etioles confirme ces resultats

Texto completoResumen
The compartmental hypothesis of neurodegeneration proposes that the neurone, long recognized to consist of morphologically and functionally distinct compartments, also houses distinct degeneration mechanisms for the soma, axon and nerve endings. Support for this hypothesis is provided by the phenomenon of the WldS (for Wallerian Degeneration, slow) mouse, a mutant in which axons survive several weeks after transection, rather than degenerating within 24-48 hours as in wild type mice, by virtue of expression of a chimeric Nmnat1/Ube4b protein. In this thesis I used the WldS-mouse to re-examine and extend the theory of compartmental neurodegeneration by focusing specifically on sensory axons and endings; and finally by considering a fourth compartment, the dendrites. The first part of this thesis reports that Ia afferent axons and their annulospiral endings are robustly protected from degeneration in WldS mice. Homozygous or heterozygous WldS mice crossbred with transgenic mice expressing fluorescent protein in neurones were sacrificed at various times after sciatic nerve transection. Fluorescence microscopy of whole mount preparations of lumbrical muscles in these mice revealed excellent preservation of annulospiral endings on muscle spindles for at least 10 days after axotomy. No significant difference was detected in the protection with age or gene copy-number in contrast to the protection of motor nerve terminals, which degenerate rapidly in heterozygote and aged homozygote WldS mice. In an attempt to explain the difference in motor and sensory protection by WldS, examination of three hypotheses was undertaken: a) differences in protein expression, tested by western blot and immunohistochemistry; b) differences in the degree of neuronal branching, tested through examination of g-motor axons and endings which have a degree of branching intermediate to motor and sensory neurons; and c) differences in the activity in the disconnected stumps, through primary culture of the saphenous and phrenic nerve, selected because they comprise largely pure sensory and motor axons respectively. The data suggest that none of these hypotheses provides a sufficient explanation for the difference between sensory and motor protection by WldS. The last part of this thesis attempts to extend the theory of compartmental degeneration. I examine a system for investigation of WldS-mediated protection of dendrites. In preliminary experiments retinal explants from transgenic mice expressing YFP in a subset of retinal ganglion-cell neurones were cultured. The dendritic arbours of these cells were shown to be amenable for repeated visualization and accessible to injury and monitoring of degeneration. Overall the data in this thesis suggest that the level of WldS -mediated protection conferred to an axon or axonal endings varies between different neuronal types. This has implications for the potential applications of WldS research to clinical problems. Specifically, the data imply that sensory neuropathies may benefit more than motor neuropathies from treatments based on the protective effects of WldS. These findings in sensory neurones also challenge some of the assumptions made about WldS- mediated protection of neurones, for example the extent of the age-effect on axonal endings. Further investigation of WldS-mediated protection in the CNS could give renewed impetus to attempts to discover targets for treatment in common neurodegenerative diseases. Finally, a system for investigation of dendritic degeneration has been piloted, suggesting that molecules involved in the degeneration of dendrites or in protection from this degeneration may be amenable to investigation in this system, prospectively extending the compartmental hypothesis of neuronal degeneration.

Texto completoResumen
Volume I has three chapters. Chapter one presents a systematic meta-synthesis which reviews fourteen qualitative research articles about mental health professionals’ experiences of patient suicide. The analysis illustrates an underlying sense of bereavement, fear and transformation. Chapter two presents an empirical research paper which explores psychotherapists’ experiences of therapy endings. The analysis suggests therapists and patients can have an intimate professional relationship which can be differentially affecting for both after the therapy ends. Chapter three is a public dissemination document which gives an accessible overview of chapters one and two. Volume II contains five clinical practice reports. The first report details the case of a woman experiencing Anxiety, Depression and suicidal ideation; formulated from two psychological models.

Evans, Elliott. "The Origin, Functions, and Histories of Germanic Adjective Endings". Thesis, Indiana University, 2019. http://pqdtopen.proquest.com/#viewpdf?dispub=13858651.
Texto completoResumen
The purpose of this dissertation is to provide an account for why Germanic languages inflect adjectives along the adjective declension choice (ADC)—i.e. as strong or weak—in addition to the typical parameters of gender, number, and case. Specifically, I examine the origin, functions, and histories of Germanic adjective endings.
The ADC, which developed in prehistoric times, could not have arisen from the Proto-Indo-European individualizing suffix as is typically assumed, since early runic examples directly contradict that account. Instead, geographically peripheral Swedish attest nominal incorporation to express definiteness, which finds corresponding examples in both Runic Germanic and other Indo-European languages and provides a more likely origin for the ADC.
The modern Germanic languages exhibit different functions for the ADC. In German it conveys syntactic nominal features that would otherwise remain unvalued and result in a crash. In Dutch and Norwegian, it conveys semantic definiteness features.
The function of the ADC in Proto-Germanic, as demonstrated through a comparison of early Germanic translations of Matthew’s Gospel, was syntactic, though distinct from German. In Proto-Germanic, weak adjectives were bound by determiners and strong adjectives were free and occupied the elsewhere environment. A series of developments happened in the history of German, attested from approximately 800 to 1300 CE. First, possessives and the indefinite article grammaticalized from adjectives into determiners. Second, many nominative inflections phonologically reduced to zero, making most predicate adjectives appear uninflected. Finally, strong attributive adjectives adopted the pronominal paradigm to replace the zero endings. In Norwegian, the system shifted from a syntactic one to a semantic one, with the two competing systems vacillating from approximately 1100 to 1500 CE. The newer semantic system, which eventually won out, aligned weak adjectives with definiteness instead of the older syntactic system in which weak adjectives were bound by a determiner.
By examining the ADC, I provide an account of a phenomenon that morphosyntactically identifies nearly all Germanic languages, while showing that significant variation in function and historical trajectory exists across the Germanic languages—both past and present.

Texto completoResumen
When talking about tonal music, we sometimes tend to take for granted the idea that the tonic should always be clearly established either at the beginning or the end. However, there are composers who sometimes deviate from the normal path by creating different types of riddles or tonal enigmas in their works. Some of these riddles can be solved later on as the piece progresses; yet others may need to bexplained with the help of some external references. This thesis examines three such examples, each of which poses its unique enigma. The second movement of Bruckner's Symphony No. 1 presents a dualism between Ab and F (paralleled by their dominants Eb and C); Brahms's Alto Rhapsody involves an enormous auxiliary cadence spanning 2/3 of the piece and a seemingly plagal cadence which turns out to be authentic with the V suppressed; and eventually, Grieg's setting of Dereinst, dereinst, Gedanke mein provides a paradoxical ending which may be understood as incorporating the composer's attitude towards the text.

Diemer, Étienne. "Intensification du procédé d’extraction, de purification et de fonctionnalisation des acides caféoylquiniques à partir de coproduits de la culture de l’endive". Electronic Thesis or Diss., Compiègne, 2024. http://www.theses.fr/2024COMP2821.
Texto completoResumen
La racine forcée d’endive est un coproduit de la culture de l’endive, produit caractéristique du Nord de la France, de la Belgique et des Pays-Bas. Actuellement sous utilisé en méthanisation ou en alimentation animale, ce coproduit contient pourtant des molécules d’intérêts à haute valeur ajoutée : les acides caféoylquiniques. Ces molécules possèdent des activités antioxydantes, anti-inflammatoires et permettent de limiter les maladies du désordre métabolique. Ce travail de thèse vise à intensifier le prétraitement, l’extraction, la purification et la fonctionnalisation des acides caféoylquiniques à partir des racines forcées pour développer de nouvelles molécules bioactives biosourcées potentiellement intéressantes pour le secteur cosmétique et nutraceutique. Une dernière partie de la thèse porte sur l’étude technico-économique du procédé pour estimer sa rentabilité économique en fonction du secteur d’application visé. La première partie porte sur l’effet des prétraitements conventionnels (découpe et séchage) ainsi que l’effet d’un prétraitement électrique par champs électriques pulsés sur les teneurs en acides caféoylquiniques dans la biomasse. L’effet de l’ajout d’une solution antioxydante lors de l’extraction est également étudié. Dans un deuxième temps, une optimisation de l’extraction est réalisée à partir de biomasse sèche et fraiche. L’influence de facteurs tels que la température, le ratio solide/liquide, ainsi que la nature du solvant a été étudiée. De plus, des cinétiques d’extraction ont été tracées pour étudier les paramètres cinétiques à l’aide d’un modèle empirique. La pureté de l’extrait obtenu étant faible, des étapes de purification sont donc nécessaires. Par la suite, les travaux se sont portés sur la purification de l’extrait brut à l’aide de résines macroporeuses ainsi que par extraction liquide/liquide. Pour la purification par résine, un screening de résines est réalisé suivi d’une optimisation des conditions opératoires de purification avec la résine choisie. Des modélisations des phénomènes d’adsorption sont réalisées pour déterminer les étapes limitantes ainsi que la capacité maximale d’adsorption. Pour l’extraction liquide/liquide, un screening de solvants verts est effectué à partir d’un milieu aqueux et hydro-éthanolique puis une optimisation des conditions opératoires avec le meilleur solvant est réalisée. La pénultième partie de la thèse cherche à fonctionnaliser par estérification les acides caféoylquiniques à partir d’une solution modèle puis d’un extrait réel. Les conditions d’estérification sont optimisées pour augmenter la vitesse de réaction ainsi que le taux de conversion. Des esters avec différentes longueurs de chaine sont obtenus et l’activité antioxydante ainsi que les propriétés anti-UV sont étudiées. La fonctionnalisation est par la suite effectuée sur un extrait réel. Une étude technico-économique conclut la thèse permettant d’ouvrir sur des perspectives quant aux conditions nécessaires à l’industrialisation du procédé de valorisation des racines forcées d’endiveForced chicory root is a by-product of Belgian endive culture, a typical crop of northern France, Belgium and the Netherlands. Currently under-utilized in methanation or animal feed, this by-product contains molecules of interest: caffeoylquinic acids. These molecules have antioxidant and anti-inflammatory properties, and a potential for reducing metabolic disorders. This thesis aims to intensify the pre-treatment, extraction, purification and functionalization of caffeoylquinic acids from forced chicory roots to develop new bioactive biosourced molecules of potential interest to the cosmetics and nutraceutical sectors. The final part of the thesis deals with a technico-economical study of the process to estimate its economic profitability in relation to the targeted application sector. The first part focuses on the effect of conventional pretreatments (cutting and drying) and the effect of pulsed electric field pretreatment on caffeoylquinic acid content in biomass. The effect of adding an antioxidant solution during extraction is also investigated. Secondly, extraction optimization is carried out using dry or fresh biomass. The influence of factors such as temperature, solid/liquid ratio and solvent type were studied. In addition, extraction kinetics were performed to study kinetic parameters using empirical models. As the purity of the extract obtained is low, purification steps are needed. The thesis then focused on purifying the crude extract obtained using macroporous resins and liquid/liquid extraction. For resin purification, resin screening was carried out, followed by optimization of the purification operating conditions with the chosen resin. Models of adsorption phenomena are carried out to identify the limiting stages and the maximum adsorption capacity. For liquid/liquid extraction, green solvent screening is carried out on aqueous and hydro-ethanolic media, followed by optimization of operating conditions with the best solvent. The penultimate part of the thesis seeks to functionalize caffeoylquinic acids by esterification, starting with a model solution and then a real extract. Esterification conditions are optimized to increase both reaction speed and conversion rate. Esters with different chain lengths were obtained, and biological activities such as antioxidant activity and anti-UV properties were studied. Functionalization is also performed with real extract. A technico-economic study concludes the thesis, opening up prospects for the industrialization of the forced chicory roots valorization process

Texto completoResumen
Ending therapy well is widely acknowledged as crucial for therapeutic gains to be maintained over time, yet numerous authors comment on the paucity of termination research. There appears to be no extant research into counsellors’ experiences of ending time-limited counselling in primary care (CPC), despite this being a rapidly-expanding area of practice, and theoretical literature suggesting elevated stress levels, ideological battles and burnout as counsellors adjust to time-limited working within Improving Access to Psychological Therapies (IAPT) services. When the ‘hallmark’ of a good ending is mutual agreement concerning client readiness, to what extent do traditional models of termination still hold? The aim of this research is provide some preliminary understanding of counsellors’ experiences of endings within this context. A qualitative design was employed. Data were collected in semi-structured interviews with six counsellors, and analysed using interpretative phenomenological analysis (IPA). Four overarching themes emerged: ‘self-experiencing’, ‘the quality of the therapeutic process’, ‘conflicting frameworks’, and ‘towards congruence’. These are related to wider literature and implications for counselling psychology (CoP) are discussed. Limitations and suggestions for future research are explored.

The aim of this study was to examine morphology of sensory terminals in the basis of mouse heart and ability of different antibodies to visualize these terminals. Our results showed that both end-net and complex unencapsulated endings can be visualized with PGP 9.5 (AbD Serotec, USA). Complex unencapsulated endings are localized in heart wall epicardium near the apertures of caudal, right cranial and left cranial veins in the right atrium. End-net terminals are diffusely distributed in all three layers (endocardium, myocardium, epicardium) of heart wall. Complex unencapsulated endings near the caudal vein aperture have the lowest area compared with the sensory endings near the other two veins apertures.

Tether, Leah Roseann. "Suspended endings : the mechanics of medieval continuation in the perceval continuations". Thesis, Durham University, 2009. http://etheses.dur.ac.uk/107/.
Texto completoResumen
The notion of ‘Continuation’ in medieval literature is a familiar one – but it is one which does not know any precise definition. Despite the existence of important texts which take the form of what we nominally call ‘Continuation’, such as Le Roman de la Rose, Le Chevalier de la Charrette and of course the Perceval Continuations, to date no work exists which specifically examines the mechanics and processes involved in actually producing a ‘Continuation’. The existence and importance of ‘Continuation’ as a genre of medieval literature are undeniable, and yet we cannot begin to claim that we fully understand it. This thesis therefore seeks to make the first tentative movements in creating a working model for understanding what some call the Poetics of Continuation, and it does so by means of close and meticulous analysis of the manuscript tradition and content of the Perceval Continuations. The Perceval Continuations (composed c.1200-1230) constitute a vast body of material which incorporates four separately authored Continuations, each of which seeks to further, in some way, the unfinished Perceval of Chrétien de Troyes – though they are not merely responses to his work. Chronologically, they were composed one after the other, and the next in line picks up where the previous left off, thus they respond intertextually to each other as well as to Chrétien, and only one actually furnishes the story as a whole with an ending. As such the Continuations offer an interesting and varied patchwork from whence to begin a study of this kind. By means of a framework of careful methodological design, incorporating theories on what constitutes an ‘end’ and what is ‘unfinished’, alongside scrutiny of other, selected, medieval ‘ends’ and ‘Continuations’, this thesis examines, first, what the manuscript tradition can tell us about the medieval view of ‘Continuation’ in terms of whether the Perceval Continuations seem to have been considered as one homogenous whole, or as several separate œuvres, and second, in terms of content and construction, what kind of ‘Continuation’ each individual text proposes, and how, mechanically, it does so. This analysis culminates in the creation of an efficient working model that aims to facilitate the further study and investigation of other medieval ‘continuatory’ texts.

Texto completoResumen
En se basant sur la littérature en marketing sur les terminaisons de prix et le pricing du luxe, cette thèse met en évidence le paradoxe résultant de l’utilisation de prix odd (i.e., des prix juste en dessous d’un nombre rond) dans le contexte des produits de luxe où, intuitivement, les prix devraient majoritairement être des nombres ronds. Les pratiques en termes de terminaisons de prix sont étudiées dans la catégorie des sacs à main de luxe. Dans une première partie, la thèse identifie les catégories de terminaison de prix utilisés et les déterminants d’utilisation. Dans une seconde partie, la thèse explore les perceptions des consommateurs concernant différentes facettes du luxe et leur perception globale du caractère luxueux d’un produit selon les terminaisons de prix utilisées. Dans une dernière partie, la thèse étudie les préférences des consommateurs de luxe pour une terminaison de prix ou l’autre. Les résultats de cette thèse offrent de nouvelles perspectives par rapport à la littérature existante sur les terminaisons de prix, dans le sens où ils indiquent que les connotations de prix inférieur, qualité inférieure et prestige inférieur, associées aux prix odd et bien établies dans la littérature n’existent pas pour les produits de luxe, ou du moins pour la catégorie des sacs à main de luxe de niveau intermédiaireDrawing from existing literature on price endings and luxury pricing, this thesis highlights the paradox of adopting odd prices (i.e., prices just below a round number) in a luxury context, where, intuitively, prices should mostly be round numbers. Price endings practices are investigated in the product category of luxury women handbags. In a first empirical analysis, different types of price endings and the determinants of their use by pricing managers are identified. In a second part, the results of two experiments measure customers’ perceptions of different facets of luxury and overall perceived luxury itself. In the last part, a conjoint analysis reveals customers’ preferences for odd price endings. The findings of this thesis challenge previous research on price endings practices, in that they show that well-know low-price, low-quality, low-prestige connotations typical of odd prices in a non-luxury context, might not subsist in a luxury environment, at least for the handbag product category and for an intermediate level of luxury

Bell, Stuart. "'Don't stop' : re-thinking the function of endings in narrative television". Thesis, University of Glasgow, 2015. http://theses.gla.ac.uk/7282/.
Texto completoResumen
This thesis argues that the study of narrative television has been limited by an adherence to accepted and commonplace conceptions of endings as derived from literary theory, particularly a preoccupation with the terminus of the text as the ultimate site of cohesion, structure, and meaning. Such common conceptions of endings, this thesis argues, are largely incompatible with the realities of television’s production and reception, and as a result the study of endings in television needs to be re-thought to pay attention to the specificities of the medium. In this regard, this thesis proposes a model of intra-narrative endings, islands of cohesion, structure, and meaning located within television texts, as a possible solution to the problem of endings in television. These intra-narrative endings maintain the functionality of traditional endings, whilst also allowing for the specificities of television as a narrative medium. The first two chapters set out the theoretical groundwork, first by exploring the essential characteristics of narrative television (serialisation, fragmentation, duration, repetition, and accumulation), then by exploring the unique relationship between narrative television and the forces of contingency. These chapters also introduce the concept of intra-narrative endings as a possible solution to the problems of television’s narrative structure, and the medium’s relationship to contingency. Following on from this my three case studies examine forms of television which have either been traditionally defined as particularly resistant to closure (soap opera and the US sitcom) or which have received little analysis in terms of their narrative structure (sports coverage). Each of these case studies provides contextual material on these televisual forms, situating them in terms of their narrative structure, before moving on to analyse them in terms of my concept of intra-narrative endings. In the case of soap opera, the chapter focusses on the death of the long running character Pat Butcher in the British soap EastEnders (BBC, 1985-), while my chapter on the US sitcom focusses on the varying levels of closure that can be located within the US sitcom, using Friends (NBC, 1993-2004) as a particular example. Finally, my chapter on sports coverage analyses the BBC’s coverage of the 2012 London Olympics, and focusses on the narratives surrounding cyclists Chris Hoy and Victoria Pendleton. Each of these case studies identifies their chosen events as intra-narrative endings within larger, ongoing texts, and analyses the various ways in which they operate within those wider texts. This thesis is intended to make a contribution to the emerging field of endings studies within television by shifting the understanding of endings away from a dominant literary model which overwhelmingly focusses on the terminus of the text, to a more televisually specific model which pays attention to the particular contexts of the medium’s production and reception.

Texto completoResumen
A escarola é uma das hortaliças folhosas mais consumidas em saladas, considerada um alimento rico em nutrientes e compostos antioxidantes. Devido ao seu preparo trabalhoso, este vegetal apresenta forte potencial para o mercado de produtos minimamente processados, porém, este produto apresenta escurecimento nas folhas durante o armazenamento. O objetivo desse trabalho foi avaliar a influência do armazenamento refrigerado, atmosfera modificada passiva e da aplicação de antioxidantes sobre os aspectos de qualidade da escarola minimamente processada. Foram realizados três experimentos. No primeiro experimento, foi avaliado o efeito do armazenamento em quatro temperaturas 0, 5, 10 e 15°C, por 20 dias a 90-95% UR. No segundo, avaliou-se a utilização da atmosfera modificada passiva pelo acondicionamento do produto em quatro embalagens plásticas: policloreto de polivinila (PVC), polietileno de baixa densidade (PEBD), polipropileno (PP) e polipropileno bi-orientado (BOPP), durante o armazenamento a 0°C e 90-95% UR por 20 dias. O último experimento objetivou verificar os efeitos da aplicação dos antioxidantes: ácido ascórbico 1%, ácido cítrico 1%, ácido oxálico 1% e ácido etilenodiamino tetra-acético (EDTA) 2% por 21 dias de armazenamento a 0°C e 90-95% UR. Em todos os experimentos foram realizadas as análises de cor, L, C e °h e o índice de escurecimento, teor de ácido ascórbico, teor de clorofila total e carotenoides totais, compostos fenólicos totais e perda de massa. Para o experimento de refrigeração, foram realizadas ainda, as análises de taxa respiratória e produção de etileno. Nos experimentos de embalagens e antioxidantes, foram realizados o monitoramento das concentrações internas de O2 e CO2 nas embalagens e a atividade das enzimas polifenoloxidase e peroxidase, sendo que para este último experimento, foram realizadas ainda, análises microbiológicas referentes a ausência ou presença de Salmonella, quantificação de coliformes totais e bactérias psicrotróficas durante o armazenamento. A temperatura de 0°C é a mais recomendável para a redução de perdas na qualidade da escarola, essa temperatura proporcionou redução da taxa respiratória e perda de massa, bem como foi a que manteve os maiores os teores de ácido ascórbico e de pigmentos dessa hortaliça. Sendo que não foram observados sintomas de dano por frio no produto. Dentre os filmes estudados, constatou-se que as concentrações de 16 % de oxigênio e 3% de dióxido de carbono geradas no interior do filme de PVC, proporcionaram o menor escurecimento das folhas e maior conservação dos teores de ácido ascórbico, clorofila e carotenoides totais no produto. Observou-se ainda, que a escarola minimamente processada apresenta sensibilidade a altas concentração de CO2. Para o último experimento, não foi verificada a presença de Salmonella em nenhum dos tratamentos. Entre os antioxidantes aplicados, verificou-se que o tratamento de ácido cítrico 1% é o mais indicado para conservação dos atributos de qualidade da escarola minimamente processada, por ter mantido baixo índice de escurecimento, os maiores teores de pigmentos e alto teor de ácido ascórbico, bem como ter proporcionado baixa perda de massa e desenvolvimento microbiológico dentro dos limites estabelecidos.Escarole is one of the most consumed leafy vegetal in salads, it is considered a rich source of nutrients and antioxidant compounds. Due to his arduous preparation for consumption or preparation of dishes, this vegetable shows a strong potential for fresh cut products market, however, this product exhibits browning on its leaves during storage. The objective of this work was to evaluate the influence of refrigerated storage, passive modified atmosphere and the application of antioxidants on quality aspects of fresh cut escarole. Three experiments were carried out. The first experiment evaluated the effect of four storage temperatures 0, 5, 10 and 15° C, for 20 days to 90-95% RH. In the second one, the effect of the use of passive modified atmosphere was evaluated by four plastic packaging: polyvinyl chloride (PVC), low density polyethylene (LDPE), polypropylene (PP) and bi-oriented polypropylene (BOPP), during storage at 0° C and 90-95% RH for 20 days. The last experiment aimed to check the effects of the application of following antioxidants: ascorbic acid 1%, citric acid 1%, oxalic acid 1% and etilenodiamino tetra-acetic acid (EDTA) 2% for a period of 21 days of storage at 0° C and 90-95% RH. In all experiments were performed the following analysis: color by L, C and °h and observation of browning index, ascorbic acid content, total chlorophyll content, total carotenoids content, total phenolic compounds content and weight loss. For the temperature experiment, the analysis of respiratory rate and ethylene production were also carried out. In the passive modified atmosphere and the antioxidants experiments, the monitoring of concentrations of O2 and CO2 in headspace of the packages and the activity of polyphenoloxidase and peroxidase enzymes were also made, and for the last experiment, were carried out microbiological analysis concerning the absence or presence of Salmonella and total coliforms and psychrotrophic bacteria counts during storage. The temperature of 0°C is the most recommended for the reduction of losses in the fresh cut escarole quality, that temperature provided respiratory rate reduction and reduction of the weight loss as well as was the one that kept the highest contents of ascorbic acid and pigments. Symptoms of chilling injury were not observed on the product during the storage. Among the films studied, it was found that concentrations of 16% oxygen and 3% carbon dioxide generated inside the PVC film, provided the minor browning index of the leaves and better conservation of levels of ascorbic acid, chlorophyll and carotenoids. It was observed that the fresh cut escarole is sensitivity to high CO2 concentrations. In the last experiment, the presence of Salmonella was not detected on the treatments. Between antioxidants applied, it was found that the treatment of citric acid 1% is the most suitable for the conservation of the fresh cut escarole quality attributes, for keeping low browning index, the highest concentrations of pigments and high content of ascorbic acid, as well as having provided low weight loss and microbiological development within the limits.

Texto completoResumen
Through an analysis of the reception of Charles Dickens’ unfinished The Mystery of Edwin Drood this thesis establishes the centrality of the figure of the author as the perceived sanction for the completed text. Through an initial analysis of completed narrative, in Arthur Conan Doyle’s Holmes stories, it shows that the ending is of particular importance as the point at which the reader can look back over the whole and confirm or disconfirm the provisional interpretations which have been made during the reading. It only makes sense to talk of unfinished texts or unfinished narratives in the context of a creative authority, generally identified as the author. An analysis of the reception of unfinished serial narratives of the late Victorian period, specifically the unfinished works of William M. Thackeray and Robert Louis Stevenson, confirms the centrality of the figure of the author in attempts to reconstruct the missing ending. The main body of the thesis provides a period-based analysis of Droodiana, the completions of and speculations about Dickens’ unfinished novel. In the analysis of the strategies employed to justify completions, and the responses to these, it establishes not only that the attempts to take on the authorial authority are perceived as sacrilegious, but that the perception of the completion-writers’ lack of the authority to posit an ending affects whether completions are read as able to complete the story: the willingness to submit to the ending (and revise provisional readings in light of it) is dependent on the perception of the authorial authority of the writer. The analysis shows that while the author-function develops over time, there is some continuity from the late Victorian period towards the present. The analysis of Droodian speculations trace their origin and development through a series of periods, showing that the variety of plots proposed masks a common concern with arriving at Dickens’ intended plot: a desire to identify the creative intention with the plot that would provide the most satisfying ending produces an increased variety over time.

Aims: Despite general agreement as to the importance of the final phase of therapy, literature concerning the way the therapeutic relationship is brought to a close focuses almost entirely on the perspective of the client. Much less is recognized about the therapist’s experience of this process. Little qualitative research has been conducted in the area. The current study therefore aims to gain︣an in-depth understanding of the therapist’s experience of a therapeutic ending. Using a qualitative approach, the study focuses upon the experiences of practicing counselling psychologists, and seeks to explore the following: How do therapists experience therapeutic endings?︣Method: Semi-structured interviews were carried out with seven practicing counselling psychologists (five females and two males; aged between 29 and 48) who each described a particular therapeutic ending that evoked a significant emotional response for them. Verbatim transcripts of the interviews were then analysed using Interpretative Phenomenological Analysis (IPA).︣Results: The analysis produced four master themes. These were: The therapeutic relationship; The ending phase and final session; Therapy as a learning process; Professional implications and considerations. A description of these master themes and the related constituent themes is presented. The results of the analysis are considered in light of existing theory and their implications for counselling psychology. These emphasize the significance of therapeutic endings and highlight the adequacy (or otherwise) of clinical supervision and professional training institutions in helping therapists manage and understand this process. Methodological considerations and suggestions for further research are presented.

Previous issue date: 2016-07-28Nesta pesquisa propomos mapear, descrever e analisar a produção acadêmica sobre Estágio Supervisionado na formação de professores, apresentada nos Encontros Nacionais de Didática e Prática de Ensino (Endipes). O foco da pesquisa pautou-se na elaboração de um estado do conhecimento sobre o referido tema no período de 2000 a 2012. Desenvolvemos uma pesquisa documental bibliográfica, de base qualitativa e quantitativa, na qual realizamos um estudo de mapeamento sobre a temática Estágio Supervisionado nos Endipes do referido período, assumindo-a como problemática de relevância significativa no campo científico da educação. O Estágio Supervisionado tem se destacado no cenário das pesquisas sobre formação de professores por sua pujante contribuição tanto para a promoção da articulação entre a teoria e a prática na formação e no trabalho docente, quanto para a constituição da identidade docente e para o desenvolvimento de ações colaborativas entre universidade e escolas de educação básica, uma vez que, por ocasião dos estágios, os licenciandos têm a oportunidade de vivenciar situações de ensino e aprendizagem e de refletir sobre a prática educativa ao mesmo tempo em que se formam como professor e pesquisador de sua atividade profissional. Desse modo, dialogamos com as produções de Pimenta (2001, 2002 e 2011), Pimenta e Lima (2004 e 2011), Lima (2012) e Nóvoa (1992, 2004 e 2009). Os resultados da materialidade evidenciam a colaboração dos Endipes para a socialização das produções, uma vez que congrega resultados dos trabalhos de pesquisadores de todo país. Nesse panorama, por meio dos textos apresentados na modalidade painel no período de 2000 a 2012, o Estágio Supervisionado ganha destaque como significativo componente curricular, eficaz para a promoção da articulação entre a teoria e prática e das ações colaborativas entre Universidade e escola, bem como para a formação do professor reflexivo, para a constituição da identidade docente e para a composição dos saberes da docência. Além dessas questões, os autores também trataram das experiências do Estágio Supervisionado e ocuparam-se em analisar as racionalidades subjacentes às concepções de formação docente.

Texto completoResumen
This thesis examines a late colonial attempt to reimagine the French empire in the Sahara, through the little-known case of the Organisation Commune des Régions Sahariennes (OCRS). This organisation, which lasted from 1957-1962, was created by the French state as an economic and social development project which would operate in the Saharan regions of Algeria, Chad, French Soudan (Mali), and Niger. This case study of the OCRS is at the intersection of a number of key developments in the field in recent years. Firstly, studies of the ends of colonial empires have moved away from discussing whether independence was 'snatched away' or given in a 'transfer of power'. The historiography now emphasises the messiness and contingency of the end of empire and questions the inevitability of the shift from empire to nation-state. Secondly, in discussions about France's (post-)colonial ties with Africa, scholars are increasingly focusing on delineating French strategies for retaining a sphere of influence in the region rather than labelling change and continuity. Thirdly, with an explosion in global and transnational history, historians stress the importance of studying connections and the 'politics of comparison' (Stoler, 2001) moving away from treating French colonial history, and particularly Franco-Algerian history, as exceptional. In light of these historiographical developments, this thesis uses the example of the OCRS to explore the possibilities and impossibilities of reimagining and ending the empire, whilst at the same time retaining control over the region. The OCRS is examined from multiple angles: as a transitional organisation that was both connected to and reflective of shifting international and domestic circumstances, as a self-aware organisation that sought to establish its success and its status in comparison with other projects across the globe and as an attempted reimagining of colonial rule where its planners sought to learn from the 'mistakes' of former planners. This thesis demonstrates how the OCRS was used as a possibility to reimagine French colonial rule, and the impossibility of this feat. French planners intended to reshape political, economic and social structures in the Sahara. Using comparisons with other, purportedly similar, socio-economic projects without colonial ties, they attempted to make these structures more palatable to a range of other actors, including African political elites. This attempt, however, was impossible because of the weight of history and the increased importance of sovereignty and self-determination in this period.

Texto completoResumen
En aquesta tesi s'han sintetitzat macrocicles nitrogenats poliinsaturats de diferents mides i s'ha estudiat la seva reactivitat. S'han preparat macrocicles de quinze i setze baules triacetilènics i de quinze baules contenint dos triples i un doble enllaç a l'estructura. S'ha estudiat la ciclotrimerització [2+2+2] d'aquests macrocicles catalitzada per metalls de transició en dissolvents orgànics convencionals o en sals foses.
S'han sintetitzat complexos de rodi contenint un lligand carbènic N-heterocíclic per tal d'utilitzar-los com a catalitzadors alternatius al complex de Wilkinson en les reaccions de ciclotrimerització dels macrocicles poliinsaturats i d'altres anàlegs oberts. Els complexos carbènics sintetitzats han presentat una eficiència lleugerament superior a la del catalitzador de Wilkinson.
També s'ha iniciat un estudi mecanístic de la cicloisomerització d'aquests macrocicles induïda tèrmicament.
Finalment, s'han preparat macrocicles de catorze i dinou baules contenint un nucli endiínic a més d'altres insaturacions i s'ha estudiat la corresponent ciclació de Bergman en estat sòlid.
In this work different sized polyunsaturated azamacrocicles were synthesized and their reactivity was studied. 15- and 16-membered triacetylenic macrocycles and 15-membered macrocycles containing two acetylenes and one olefin were synthesized. The transition metal catalyzed [2+2+2] cyclotrimerization of the polyunsaturated macrocycles was studied in organic solvents or molten salts.
Rhodium complexes containing a N-heterocyclic carbene (NHC) ligand were prepared in order to be used as alternatives to the Wilkinson's catalyst in the cyclotrimerization reaction of the polyunsaturated macrocycles and other open-chained analogues. The yields were slightly higher to those previously obtained with the Wilkinson's catalyst, showing that NHC can be used as alternative ligands to the phosphanes.
A mechanistic study of the thermally induced cycloisomerization of the above-mentioned macrocycles was initiated.
Finally, 14- and 19-membered azamacrocycles containing an enediyne system and other unsaturations were synthesized and their solid-state Bergman cyclization was studied.

Mestrado em Engenharia do Ambiente - Instituto Superior de AgronomiaIn this dissertation, the aim was to evaluate and compare the performance of biodegradable mulch relatively to conventional polyethylene. For this purpose three different “mulches” were tested: polyethylene (PE) and two biodegradable "Short Cycle" (SC) and "Salads" (S) developed from the Mater-Bi™ matrix. Escarole (Cichorium endivia L.) crop cycle was monitored along the experimental study implemented at real scale. The monitoring plan was developed to evaluate the crop productivity and the impact of the different “mulches” in terms of moisture and soil temperature. The results achieved during this study showed the adaptability of biodegradable plastics to the soil and weather conditions, checking a significant difference in productivity of plants covered with plastic S relative to the other two modes (PE and SC). Given that to date there is no biodegradation studies in the Alentejo region of Portugal soils, it was also important to check the level of biodegradability of these new plastic films following the norm DIN EN ISO 17556. The results obtained in this work can be concluded that biodegradable plastics seem like a good solution to replace the PE, yet research and development of these new plastics should continue to hold
