This essay provides an attempt to reflect the notions of violence, right or law and fate in Benjamin’s Zur Kritik der Gewalt, in order to clarify his very dense historical-philosophical reflection on the constitutive relation between violence and law. In contrast to what is most often the case, this essay will not address the notion of divine violence in a direct sense, but mainly focus on Benjamin’s discussion on right and law. The complex of his historical reflection, his attempt to articulate what he calls the “historical function” not only of violence, but also of law, is crucially related to the notion of fate. First and foremost fate is what turns the suspicion of the perniciousness of this historical function into a certainty, actualizing its destruction as something obligatory in terms of divine violence, by deepening the analysis and revealing the fundamental relation between law and violence. By pointing out the function of violence within the sphere of law, Benjamin not only states that violence cannot be thought otherwise than in relation to this sphere, but also that the relation between law and violence has to be thought in terms of the “uncertainty of the legal threat”. The deepest meaning of both the “uncertainty” and “the legal threat” emerges from the “sphere of fate”, and by reflecting this notion this essay will try to outline the legal complex and the meaning of fate in terms of guilt, misfortune and judgement, and how it is constituted with reference to the notion of “bare life” – that is, the marked bearer of guilt. The complexity of the relation between violence and law shows itself in the circumstance that this “bearer” in terms of guilt also becomes the bearer of the relation itself, bearing the validity of law, or more precise, the being in force of law. This also conceptualizes law as a phenomenon of frontiers, in a double sense that will explain the meaning of guilt and fate in terms of infringement, but also the legal relation to violence understood as a line constituting an inside and an outside within the sphere of law itself. And this will also explain why the meaning of justification of violence – significantly related to fate and the phenomenon of this line – never can be understood ethically.

From the Proceedings of the 1971 Meetings of the Arizona Section - American Water Resources Assn. and the Hydrology Section - Arizona Academy of Science - April 22-23, 1971, Tempe, Arizona / A study was made to determine how the evaporation rate from a bare Adelanto loam soil in Phoenix changes with season and with time since the last irrigation. The evaporation rates were determined by precision lysimeters in a bare field, with measurements being taken in every month of the year for at least a week after irrigation. The data exhibited a cosine-shaped curve, with a maximum evaporation rate of about 5 mm/day in summer and a minimum rate of about 2 mm/day in winter. By the seventh day, seasonal effects virtually disappear, and the evaporation rate is the same in both summer and winter, being about 2 mm/day after the 7th day and about 0.75 mm/day after the 21st day. It is generally accepted that soil dries in 3 stages, and the transition between the 1st and 2nd stages occurs when atmospheric conditions are no longer critical. In previous laboratory studies of soil drying, with constant atmospheric conditions, stage 1 was easily distinguished from stage II, and these results correlated closely with the equations of Gardner and Hillel. The individual drying curves of this field study were qualitatively different from the laboratory studies and did not confirm the predictions of the equations, suggesting that diurnal variations in temperature and other meteorological parameters have caused the difference.

Σκοπός: Η μελέτη είχε ως σκοπό την διερεύνηση της ασφάλειας και της αποτελεσματικότητας των sirolimus-eluting stent, σε σχέση με τα απλά μεταλλικά stent, στα πλαίσια αγγειοπλαστικής των κνημιαίων αγγείων, σε ασθενείς με χρόνια κρίσιμη ισχαιμία του κάτω άκρου. Πρόκειται για μια προοπτική ελεγχόμενη, κλινική μελέτη με διπλό σκέλος. Τα stent τοποθετήθηκαν σε περιπτώσεις μη ικανοποιητικής αγγειοπλαστικής (δηλ. σε περιπτώσεις ελαστικής επαναφοράς-υπολειμματικής στένωσης >30% και σε περιπτώσεις διαχωρισμού). Οι ασθενείς ελέγχθηκαν κλινικά και αγγειογραφικά στο εξάμηνο και στο 1 έτος. Ασθενείς και μέθοδοι: 29 ασθενείς, εκ των οποίων 8 γυναίκες και 21 άνδρες, με μέση ηλικία τα 68,7 έτη υποβλήθηκαν σε αγγειοπλαστική στα κνημιαία αγγεία, με απλά μεταλλικά stent, ομάδα Β. Σε αυτή την ομάδα τοποθετήθηκαν απλά stent σε 65 αλλοιώσεις, εκ των οποίων 38 στενώσεις και 27 αποφράξεις σε συνολικά 40 κνημιαία αγγεία. Άλλοι 29 ασθενείς, 8 γυναίκες και 21 άνδρες, με μέση ηλικία τα 68,8 έτη αντιμετωπίστηκαν με sirolimus-eluting stent, ομάδα S. Σε αυτή την ομάδα αντιμετωπίστηκαν 66 αλλοιώσεις εκ των οποίων 46 στενώσεις και 20 αποφράξεις, σε 41 συνολικά αγγεία. Οι ασθενείς επανελέγχθηκαν κλινικά και με ενδαρτηριακή αγγειογραφία στους 6 μήνες και στο 1 έτος, μετά την αρχική επέμβαση. Έγινε στατιστική ανάλυση των αποτελεσμάτων. Αποτελέσματα: Οι συνοδές νόσοι ήταν περισσότερες στην ομάδα S (όπως η συμπτωματική νόσος από την καρδιά και τις καρωτίδες, καθώς και η υπερλιπιδαιμία, p<0.05). Η τεχνική επιτυχία ήταν 96,6% (28/29 άκρα) στην ομάδα Β έναντι 100% (29/29 άκρα) στην ομάδα S (p=0.16) Στον επανέλεγχο εξαμήνου: Η βατότητα ήταν 68,1% στην ομάδα Β και 92,0% στην ομάδα S, (p<0.002). Τα μεγαλύτερα ποσοστά βατότητας των sirolimus-eluting stent, μετά από πολυπαραγοντική regression analysis είχαν OR 5.625, με 95% CI 1.711- 18.493, που ήταν στατιστικά σημαντικό (p=0.004). Η δυαδική επαναστένωση εντός του stent ήταν 55,3% ενώ η επαναστένωση στα άκρα του stent ήταν 66,0% στους ασθενείς με τα απλά μεταλλικά stent. Αντιθέτως τα ποσοστά στους ασθενείς με sirolimus-eluting stent ήταν 4,0% και 32,0% αντίστοιχα. Συγκεκριμένα η επαναστένωση εντός του stent είχε OR 0.067, με 95% CI 0.021-0.017, και η επαναστένωση στα άκρα του stent είχε OR 0.229 με 95% CI 0.099-0.533. Και τα δύο ήταν ήταν στατιστικά σημαντικά με p<0.001 και p=0.001, αντίστοιχα. Τα συνολικά ποσοστά επανεπέμβασης (TLR) στο εξάμηνο ήταν 17,0% στην ομάδα Β έναντι 4,0% στην ομάδα S, (OR 0.057, με 95% CI 0.008-0.426). Το αποτέλεσμα ήταν επίσης στατιστικά σημαντικό υπέρ των sirolimus stent. (p=0.02) Η διάσωση του άκρου ήταν 100% και στις δύο ομάδες. Η θνησιμότητα και ο ελάσσων ακρωτηριασμός στο εξάμηνο ήταν 6,9% και 17,2% στην ομάδα Β έναντι 10,3% και 3,4% στην ομάδα S (p=0.32 και p=0.04, αντίστοιχα). Στον επανέλεγχο έτους: Τα sirolimus-eluting stent σχετίζoνταν και πάλι με καλύτερη πρωτογενή βατότητα (OR 10.401, με 95% CI 3.425-31.589, p<0.001) και σημαντικά μειωμένη δυαδική επαναστένωση εντός του stent (OR 0.156, με 95% CI 0.060-0.407, p<0.001), καθώς και στα άκρα του stent. (OR 0.089, με 95% CI 0.023-0.349, p=0.001) Τα ποσοστά επανεπέμβασης στις βλάβες (TLR) ήταν πολύ μικρότερα στην ομάδα του sirolimus (OR 0.238, με 95% CI 0.067-0.841, p=0.026) . Δεν υπήρξαν στατιστικά σημαντικές διαφορές ανάμεσα στις δύο ομάδες Β και S όσον αφορά στα ποσοστά θνησιμότητας 10,3% έναντι 13,8%, στη διάσωση του άκρου 100% έναντι 96% και στους ελάσσονες ακρωτηριασμούς 17,2% έναντι 10,3% αντίστοιχα. Συμπεράσματα: Τα sirolimus-eluting stents περιορίζουν την ενδοθηλιακή υπερπλασία στα κνημιαία αγγεία. Η εφαρμογή τους έχει ως αποτέλεσμα την σημαντική μείωση των ποσοστών επαναστένωσης και μειώνει την ανάγκη για επανεπεμβάσεις. / Aim : The purpose of our study was to investigate the 6-month and 1-year angiographic and clinical outcome in the setting of a controlled clinical study. The study examined the safety and relative effectiveness of sirolimus-eluting stents opposed to conventional metal stents, in the infrapopliteal vessels, in patients with critical limb ischemia (CLI). The stents were used in a bail-out setting during infrapopliteal endovascular procedures, i. e. stenting was carried out in cases of suboptimal angioplasty results (recoil - residual stenosis >30%, or in cases of dissection, after angioplasty). Patients and Methods: Twenty-nine patients comprising 8 women and 21 men with a mean age of 68.7 years were submitted to infrapopliteal revascularization with conventional (bare) metal stents, called group B. In these patients 65 lesions were treated with bare stents, of whom 38 stenoses and 27 occlusions, in a total of 40 infrapopliteal vessels. Another 29 patients, again 8 women and 21 men, with a mean age of 68.8 years were treated with sirolimus-eluting stents, named group S. There were 66 lesions in this group with 46 of them stenoses and 20 occlusions, in a total of 41 arteries. Patients were followed-up with clinical examination and intrarterial angiography 6 months and 1 year after the procedure. Both results were subsequently analyzed statistically. 135 Results: Co morbidities like symptomatic cardiac and carotid disease, as well as hyperlipidemia were more prominent in group S (p<0.05). Technical success was 96.6% (28/29 limbs) in group B against 100.0% (29/29 limbs) in group S (p=0.16). During 6-month patient follow-up: Primary patency was 68.1% in group B opposed to 92.0% in group S (p<0.002). Sirolimus-eluting stents exhibited higher primary patency with OR 5.625 and 95% CI 1.711-18.493, which was statistically significant (p=0.004). Binary in-stent restenosis rate was 55.3% while in-segment restenosis was 66.0%, in patients who had received bare metal stents. In opposition the respective restenosis rates, in patients with sirolimus-eluting stents were 4.0% and 32.0%. Diminished in-stent (OR 0.067 with 95% CI 0.021-0.017) and insegment (OR 0.229 with 95% CI 0.099-0.533) binary restenosis were both statistically significant with p values being p<0.001 and p=0.001 respectively. Collective target lesion re-intervention (TLR) at 6 month follow-up was 17.0% in group B against 4.0% (OR 0.057 with 95% CI 0.008-0.426) in group S, which proved again statistically significant for sirolimus stents (p=0.02). Six-month limb salvage rate was 100% in both groups. Six-month mortality and minor amputation rates were respectively 6.9% and 17.2%, in group B versus 10.3% and 3.4%, in group S (p=0.32 and p=0.04, respectively). During 1-year patient follow-up: 136 SES were still related with better primary patency rate (OR 10.401 with 95% CI 3.425-31.589, p<0.001) and considerably lesser events of in-stent binary restenosis (OR 0.156, 95% CI 0.060-0.407, p<0.001) as well as insegment (OR 0.089, 95% CI 0.023-0.349, p=0.001) binary restenosis. Target lesion re-intervention (TLR), was much lower in the SES patients group during 1-year follow-up (OR 0.238 with 95% CI 0.067-0.841, p=0.026) . At 1 year follow-up there were no statistically significant differences among group B and group S regarding mortality (10.3% against 13.8%), limb salvage rates (100% vs. 96%) and minor amputation (17.2% vs. 10.3%). Conclusions: Sirolimus-eluting stents appear to limit intimal hyperplasia in the infrapopliteal vessels. The use of sirolimus-eluting stents decreases considerably restenosis rates in the infrapopliteal vessels and reduces the need for repeat interventions

Este trabalho teve como objetivos determinar a prevalência de propriedades de caprinos leiteiros positivas e de animais soropositivos para leptospirose no semiárido paraibano, bem como identificar fatores de risco associados à prevalência de propriedades positivas. A amostragem foi delineada para a determinação da prevalência de propriedades positivas (focos) e de animais soropositivos para a infecção por Leptospira spp. No total, foram colhidas amostras de sangue de 975 animais procedentes de 110 propriedades leiteiras localizadas no Munícipio de Monteiro, microrregião do Cariri Ocidental, Estado da Paraíba. Para o diagnóstico da infecção por Leptospira spp., foi utilizado o teste de soroaglutinação microscópica (SAM), utilizando como antígenos 24 sorovares. Uma propriedade foi considerada foco quando apresentou pelo menos um animal soropositivo. As prevalências de propriedades positivas e de animais soropositivos foram de 43,6% (IC 95% = 34,2% - 53,4%) e de 8,7% (IC 95% = 5,7% - 12,9%), respectivamente. Nos animais, os sorovares mais frequentes foram Autumnalis (1,74%; IC 95% = 0,97% – 3,09%), Sentot (1,71%; IC 95% = 0,82% – 3,52%) e Whitcomb (1,39%; IC 95% = 0,65% – 2,93%), e nas propriedades, os sorovares Autumnalis (10,9%; IC 95% = 5,8% – 18,3%), Whitcomb (8,2%; IC 95% = 3,8% – 15,0%) e Sentot e Patoc (7,3%; IC 95% = 3,2% – 13,8%) foram os mais frequentes. Presença de roedores (OR = 2,78, P = 0,015) foi identificada como fator de risco. Também houve associação entre o histórico de infertilidade (OR = 14,74, P = 0,015) e a prevalência de rebanhos positivos. Sugere-se que a infecção está distribuída em caprinos da região, e um programa de controle de roedores deve ser incluído nas práticas de manejo dos rebanhos com o intuito de reduzir a transmissão do agente e, consequentemente, reduzir a prevalência de rebanhos positivos e ocorrência de problemas reprodutivos, tais como infertilidade. / Leptospirosis in small ruminants is a disease that can causes economic losses due to occurrence of abortions, stillbirths and decreased milk production. This work aimed to determine the prevalence of positive dairy goat herds and seropositive animals for leptospirosis in semiarid region of Paraíba State. Sampling was designed to determine the prevalence of positive herds (foci) and seropositive animals for leptospirosis. A total of 975 serum samples were collected from goats from 110 dairy herds in the Monteiro, Cariri Ocidental microregion of the Paraiba State. For the serological diagnosis of leptospirosis the microscopic agglutination test (MAT) was carried out usind 24 Leptospiraspp. serovars as antigens. A herd was considered positive when presented at least one seropositive animal. The prevalence of positive herds and seropositive animals were 43.6% (95% CI = 34.2% - 53.4%) and 8.7% (95% CI = 58.7% - 12.9%), respectively. The most frequent serovars in animals were Autumnalis (1.74%; 95% CI = 0.97% – 3.09%), Sentot (1.71%; 95% CI = 0.82% - 3.52%) and Whitcomb (1.39%; 95% CI = 0.65% – 2.93%), and by herd, serovars Autumnalis (10.9%; 95% CI = 5.8% – 18.3%), Whitcomb (8.2%; 95% CI = 3.8% – 15.0%) and Sentot and Patoc (7.3%; 95% CI = 3.2% – 13.8%) were the most frequent. Presence of rodents (OR = 2.78; P = 0.015) was identified as a risk factor. There was also association between history of infertility (OR = 14.74; P = 0.015) and prevalence of positive flocks. It is suggested that leptospirosis is spread in goats in the region, and that a program of rodent control should be included in the flock management practices aiming to reduce transmission of the agent and then to reduce prevalence of positive flocks and occurrence of reproductive disorders such as impaired fertility.

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / The objective of this research was to determine plant growth and development and fruit yield of the strawberry crop from bare root and plug transplants with different crown diameters. Bare roots transplants were produced by rooting stolons and plug transplants from runner tips collected and rooted in a substrate growing bed. Three classes of crown diameters were compared, in a 2 x 3 factorial and randomized block experimental design, with four replications, 16 plants per plot and a density of 6.6 plants m-2. For bare root transplants, crown diameters were between 3.0 and 5.0 (class 1); 5.1 and 8.0 (class 2) and greater than 8.1 mm (class 3). For plug transplants, runner tips were screened between 2.0 and 3.9 (class 1); 4.0 and 5.5 (class 2) and 5.6 to 7.0 mm (class 3). Transplants of both types were planted at April 16th, 2008, and at this date, crown diameter, shoot and root dry mass and number of leaves were higher in all classes of plug transplants. Ripe fruits were harvested from June 15th to November 7th, 2008, and fresh fruit yield was determined. Plant growth and development were determined at last harvest. Higher growth, development and fruit yield were obtained in plants from plug transplants. For bare root transplants, crown diameters higher than 5.1 mm can be used while for plug transplants the crown diameter of runner tips does not affect plant growth and fruit yield. / O objetivo deste trabalho foi determinar o crescimento e o desenvolvimento da planta e a produtividade de frutas de morangueiro com o emprego de mudas de raízes nuas e de torrão com diferentes diâmetros de coroa. As mudas de raízes nuas foram produzidas pelo enraizamento dos estolões e aquelas de torrão a partir de pontas de estolões coletadas e enraizadas em leito de cultivo preenchido com substrato. Três classes de diâmetro de coroa foram comparadas, em um esquema fatorial 2 x 3, em delineamento blocos ao acaso, com quatro repetições, 16 plantas por parcela e densidade de 6,6 plantas m-2. Nas mudas de raízes nuas os diâmetros de coroa foram entre 3,0 e 5,0 (classe 1), 5,1 e 8,0 (classe 2) e maior do que 8,1 mm (classe 3). Naquelas de torrão, as pontas de estolão foram classificadas entre 2,0 e 3,9 (classe 1), 4,0 e 5,5 (classe 2) e 5,6 a 7,0 mm (classe 3). As mudas de ambos os tipos foram plantadas em 16 de abril de 2008 e nessa data o diâmetro da coroa, a massa seca da parte aérea e das raízes e o número de folhas foram mais elevados nas mudas com torrão. As frutas foram colhidas maduras entre 15 de junho e sete de novembro de 2008 e a produção de frutas foi determinada. Nesta data foi determinado também o crescimento e desenvolvimento das plantas. Maior crescimento, desenvolvimento e produção de frutas foram obtidos com o emprego de mudas com torrão. Com mudas de raízes nuas as classes 2 e 3 devem ser empregadas, enquanto nas mudas com torrão o diâmetro da coroa da pontas de estolão não influencia a produção de frutas.

The objectives of this research were to select new strawberry clones for the estate of Rio Grande do Sul, Brazil, and to develop methods of multiplication to obtain disease-free transplants with high physiological quality. Five advanced strawberry clones from the Breeding Program and two controls were evaluated in an annual hill system in low tunnels from April to December, 2006. A closed soilless system was developed, based on a growing bed with substrate over a cement tile. A nutrient solution was delivered from a reservoir to the upper end of the tile and drained off back by gravity. An inert substrate (sand) and an organic substrate (Plantmax®) and two advanced strawberry clones were tested. In another experiment fruit yield of plug transplants of different sizes was compared to that of bare-root transplants. Plug transplants were produced rooting runner tips in plastic trays with different volumes of organic substrate. Bare-root transplants were produced in the closed soilless growing system described above. Clones LBD 15.1, LBH 27.2, LBD 35.2 and LBG 121.4 were identified as having potential to be used in the estate of RS. These clones combine earliness, high yield and fruit quality, high content of bioactive compounds and resistance to diseases. A high number of healthy bare-root and runner tips with high quality were obtained with both substrates and both clones. A higher early fruit yield during fall and winter was obtained with plug transplants. Both plug and bare-root transplants reached a high total yield. It was concluded that selected strawberry clones of this research can be recommended to substitute commercial cultivars now planted in the RS or used in combination with them and that disease-free bare-root transplants and runner tips for plug transplants, both with high physiological quality can be produced in the closed soilless system, providing a sustainable alternative for nurseries. / Os objetivos deste trabalho foram selecionar novos clones de morangueiro para o RS e desenvolver um sistema de multiplicação para a obtenção de mudas com alta qualidade fisiológica e sanitária. Foram avaliados cinco clones avançados do Programa de Melhoramento e duas testemunhas, em túneis baixos, durante os meses de abril e dezembro de 2006. Para a multiplicação foi utilizado um sistema fechado sem solo, baseado em um leito de cultivo com substrato sobre telhas de fibrocimento. A circulação da solução nutritiva foi feita a partir de um reservatório até a extremidade mais alta da telha, drenando por gravidade. Como substrato, testou-se a areia na categoria inerte e o Plantmax® na categoria orgânica, com dois clones. Em outro experimento foi comparada a produtividade de mudas com torrão de diferentes tamanhos e com raízes nuas. As mudas com torrão foram produzidas a partir de pontas de estolão enraizadas em bandejas com diferentes volumes de substrato orgânico. As mudas com raízes nuas foram provenientes do sistema fechado sem solo. Foram identificados os clones LBD 15.1, LBH 27.2, LBD 35.2 e LBG 121.4 com potencial para serem cultivados no RS. Esses clones combinam alta produtividade precoce e total, qualidade de fruta, conteúdo de componentes bioativos na fruta e resistência às doenças. Um alto número de mudas e pontas de estolão sadias e de alta qualidade foi obtido no sistema fechado sem solo com ambos os substratos e clones. As mudas com torrão apresentaram maior produtividade precoce no outono e inverno. Tanto as mudas com torrão como as de raízes nuas alcançaram elevada produtividade total. Concluiu-se que os novos clones selecionados podem ser indicados em substituição ou em combinação com as cultivares atualmente em uso no RS e que o sistema fechado sem solo é uma alternativa sustentável para ser empregada na produção de mudas com raízes nuas e de pontas de estolão para mudas com torrão.

In a complementary manner, it intends also to evaluate if the own latin american history represents an incentive to researchers of different knowledge's areas get help in the Agamben's teachings, in reason to a convergency of theories (Homo Sacer, State of Exception, bare life, biopolitic, camp, etc) and facts (colonization, dictatorial regimes, violence state, etc.). At the end, original manners to enrich reasonings and debates about important social political problems will also be evaluated, using, for that, concepts developed by Giorgio Agamben, writer that, necessary to register, owns a theoretical framework rich, dense, sometimes complex, but, first off all, quite appropriate to face actual questions related to the natural tension between the State and the Individual and, therefore, related to the own life. / A proposta inicial desta dissertação concentra-se, principalmente, na procura de indicativos de que a obra do escritor italiano Giorgio Agamben influencie de maneira significativa a literatura político acadêmica produzida na América Latina. De modo complementar, pretendese avaliar também se a própria história latino americana representa um incentivo para que pesquisadores de diferentes áreas do conhecimento recorram aos ensinamentos de Agamben em razão de uma convergência entre teorias (Homo Sacer, estado de exceção, vida nua, biopolítica, campo, etc) e fatos (colonização, regimes ditatoriais, violência estatal, etc). Por fim, serão avaliadas também maneiras originais de enriquecimento de raciocínios e debates elaborados sobre importantes problemas sociopolíticos, utilizando, para tanto, conceitos desenvolvidos por Giorgio Agamben, autor que, necessário registrar, possui um arcabouço teórico rico, denso, algumas vezes complexo, mas, acima de tudo, sobremodo apropriado para o enfrentamento de questões atuais e relacionadas à tensão natural entre o Estado e o indivíduo e, portanto, à própria vida.

Fundamentos: O implante de stents coronários constitui-se na técnica mais prevalente de revascularização percutânea, em especial pela prevenção da reestenose, quando comparado às intervenções com o balão. No entanto, a reestenose intra-stent, que ocorre em cerca de 25% dos casos, restringe os seus benefícios clínicos e econômicos tardios. Demonstrou-se que a hiperplasia neo-intimal decorrente da reação da parede vascular causada pelo implante do stent, é responsável pelas recidivas. Interroga-se se um protocolo de medicamentos contemplando doses máximas de manutenção de clopidogrel e atorvastatina poderia reduzir a hiperplasia neo-intimal e a reestenose. Objetivos: O objetivo primário foi aferir se esta associação de medicamentos reduziria o volume de hiperplasia neo-intimal (35% ou mais), expressa pela obstrução volumétrica da luz, mensurada pelo ultrassom intracoronário, 12 meses após a intervenção. Os objetivos secundários foram: os resultados da angiografia quantitativa e os eventos cardíacos adversos maiores (óbito, infarto e revascularização do vaso-alvo). Casuística e métodos: Foram incluídos casos eletivos e com lesões primárias nas artérias naturais. Os pacientes foram tratados com stents não farmacológicos e randomizados em dois grupos: A, com 50 pacientes medicados com doses máximas de clopidogrel e atorvastatina; e grupo B com 50 casos, medicados com 75mg de clopidogrel e doses de sinvastatina rotineiramente prescritas para obtenção das metas recomendadas para controle lipídico. Resultados: Ambos os grupos não apresentaram diferenças significantes em relação às características clínicas, angiográficas e técnicas, com exceção do diabetes, mais comum em A (36% vs 16%; p=0,02). Aos 12 meses de evolução, observaram-se eventos cardíacos maiores (12% versus 18%; p = 0,56) e revascularização do vaso-alvo (4% versus 2%; p>0,99) sem diferença significante. Nova angiografia coronária foi obtida em 98% dos casos dos dois grupos, observando-se taxa de reestenose de 8,1% e 8,2% nos grupos A e B (p>0,99). A perda tardia da luz arterial foi semelhante [0,9 mm (DP 0,5 mm) versus 1,1 mm (DP 0,7 mm); p = 0,22], o mesmo acontecendo com o diâmetro mínimo da luz [2,2 mm (DP 0,6 mm) versus 1,9 mm (DP 0,6 mm); p = 0,12]. Realizou-se ultrassom intracoronário em 98% dos pacientes de ambos os grupos, observando-se obstrução do volume da luz de 36,3% (DP 10,3%) no grupo A e de 40,1% (DP 10,9%) no grupo B (p = 0,14). Conclusões: Os resultados deste estudo demonstram que: 1) a terapêutica adjunta utilizando doses máximas de clopidogrel 150 mg/dia e atorvastatina 80 mg/dia não reduz o volume de hiperplasia neo-intimal, expressa pela obstrução volumétrica da luz; 2) as variáveis da angiografia quantitativa e os eventos cardíacos adversos maiores não mostraram diferenças significativas entre os dois grupos. / Coronary stent implantation is the current technique of choice in patients undergoing percutaneous intervention. They effectively reduce acute occlusion and restenosis even in complex lesions. However, instent restenosis occurs in up to 25% of the treated cases and there are several theories elaborating the possible relation between coronary artery thrombosis and inflammation to neointimal proliferation and the mechanism of obstruction recurrence. There are questions whether an optimized medical treatment based on maximum doses of Clopidogrel and Atorvastatin could limit neointimal hyperplasia and restenosis. Objectives: Primary endpoint was to assess the efficacy of this scheme in reducing neointimal hyperplasia volume (XX% or more), according to intravascular ultrasound measurements, 12 months after the index intervention. Secondary endpoints were quantitative angiography measurements and major adverse cardiac events (death, myocardial infarction and target vessel revascularization). Methods: We included patients with de novo lesions undergoing elective implantation of uncoated stents. Patients were divided according to the drug regimen into Group A - 50 patients receiving maximal atorvastatin and clopidogrel doses; and Group B - 50 cases treated with standard clopidogrel and simvastatin doses. Results: Groups were similar concerning clinical and angiographic characteristics, except for diabetes, more frequent in Group A (36% vs 16%, p = 0.02). At the end of 12 months major cardiac events (12% versus 18%, p = 0.56) and target vessel revascularization (4% versus 2%, p> 0.99) did not show differences between groups. Coronary angiography was obtained in 98% of the cases and the restenosis rate was 8.1% (A group) and 8,2% (B group) (p> 0.99). Late luminal loss was similar [0.9 mm (SD 0.5 mm) versus 1.1 mm (SD 0.7 mm), p = 0.22], as well as the minimum lumen diameter [2.2 mm (SD 0.6 mm) versus 1.9 mm (SD 0.6 mm), p = 0.12]. IVUS was done in 98% of patients in both groups, and the volume of neointimal hyperplasia was not significantly different in both groups [61.8 mm 3 (SD 35.4 mm3) mm3 versus 66.3 (SD 31.6 mm3), p = 0.58]. Luminal volume obstruction was 36.3% (SD 10.3%) in group A and 40.1% (SD 10.9%) in group B (p = 0.14). Conclusions: According to our results we may conclude that: 1) the therapeutic regimen using maximum doses of atorvastatin and clopidogrel did not reduce the volume of neointimal hyperplasia, 2) restenosis rate, quantitative angiography results and the rate of major adverse cardiac events were not affected by the treatment regimen.

Bien que les travaux existants aient montré que les noms sans déterminant étaient particulièrement fréquents dans les syntagmes prépositionnels, les mécanismes régissant leur emploi dans les SP demeurent assez mal connus. Cette thèse présente les résultats d’une étude de corpus synchronique portant sur certains SP spatio-temporels sans déterminant de l’anglais et du français. Nous montrons que ces SP sont extrêmement hétérogènes sur le plan syntaxique, lexical, sémantique et pragmatique ; ils s’inscrivent sur un gradient allant d’expressions pleinement figées et opaques à des séquences transparentes, modifiables et productives. Nos données n’étayent pas l’hypothèse d’un phénomène unifié et strictement grammatical. Cependant, ces SP ne peuvent être simplement considérés comme une collection d’anomalies sans rapport les unes avec les autres ; certains d’entre eux appartiennent à des groupements productifs dans lesquels la syntaxe marquée va de pair avec un sens marqué. Les différences entre les SP anglais et français peuvent tenir soit à la productivité des groupements, soit à leurs caractéristiques sémantiques et/ou pragmatiques, qui reflètent la place et la saillance des noms sans déterminant dans les deux langues. Ce travail montre que l’application de l’analyse constructionnelle à ces SP éclaire leur intégration dans le système linguistique tout en permettant une typologie fine ; il suggère que des interactions plus importantes entre phraséologie et grammaire des constructions seraient particulièrement intéressantes pour l’étude des « moules » phraséologiques et des expressions polylexicales syntaxiquement marquées. / Although previous research has shown that bare nouns are particularly frequent in prepositional phrases, the mechanisms underlying their use in PPs remain a relatively understudied topic. This thesis presents the results of a synchronic, corpus-based analysis of several groups of English and French spatio-temporal PPs. The case studies show that determinerless PPs are syntactically, lexically, semantically and pragmatically highly heterogeneous, ranging from fully fixed, opaque expressions to transparent, modifiable and productive sequences. The corpus data does not support the hypothesis of a unified, strictly grammatical phenomenon. However, these PPs cannot be explained away as a mere collection of unrelated anomalies; some of them cluster into productive sub-groupings in which marked syntax correlates with marked meaning. The differences between the French and English PPs can pertain either to the productivity of the groupings, or to their semantic and/or pragmatic properties. In the latter case, the contrasts reflect the place and salience of bare noun constructions in each language. The application of constructional analysis to the PPs is shown to be an illuminating way of accounting for their integration into the linguistic system whilst allowing for a fine-grained typology. This thesis argues that a greater interaction between phraseology and construction grammar would be of particular interest for the study of phraseological “patterns” and syntactically marked multi-word constructs.

The objective of the thesis is to describe and compare the modifying uses of two adjectives which can appear both as premodifiers as well as bare postmodifiers, namely available and responsible. Both modifying positions are examined with respect to the textual environment, the complexity of noun phrases and adjective phrases in which the adjectives function, reference and other features in order to outline the patterns in which these two adjectives appear. The data for the analytical part have been extracted from the British National Corpus using the basic query and limiting the search to the written part of the corpus. After manual assessment of the initial samples of 500 concordance lines, 154 concordance lines containing the adjective available and 147 containing the adjective responsible proved to be suitable for the analysis. The final samples of the data are further categorized and analysed concerning the complexity of the noun phrase, premodification, postmodification and complementation of the adjectives, semantic preference of the head nouns, and the motivation for the pre- or postnominal placement of the modifiers. Key words: adjective, adjective phrase, premodification, postmodification, complementation, attributive function, predicative function, postpositive function, bare adjective,...
