Une cour à l'épreuve de la conquête : la société curiale et Naples, capitale d'Alphonse le Magnanime (1416-1458) / A court in a Time of Conquest : Court Society and Naples, capital city of King Alphonso the Magnanimous (1416-1458)

Chilà, Roxane 29 November 2014 (has links)
Ma thèse porte sur l'entourage institutionnel d'Alphonse le Magnanime en Italie méridionale, suite à la conquête de Naples par ce roi d'Aragon en 1442. Il s'agit de proposer une étude approfondie d'un groupe social et de l'institution curiale. L'hôtel royal a fait l'objet d'ordonnances en Aragon en 1344 sous le règne de Pierre IV. Mais l'arrivée sur le trône aragonais des Trastamare en 1412, avec l'élection de Ferdinand Ier, le père d'Alphonse le Magnanime, puis la conquête par ce dernier du Regno, pose la question des transformations de cette institution. La principale est l'interruption de la tradition des ordonnances, qui prive l'historien de sources normatives pour l'étude de cette période de bouleversements. La cour est restée jusqu'à présent un point aveugle de l'historiographie de la dynastie et de cet État impérial et composite qu'est la couronne d'Aragon au XVe siècle, alors qu'elle en est le rouage administratif essentiel.Les officiers appartenant à la société curiale sont présentés comme un ensemble cohérent du point de vue national et sociologique par les chroniques napolitaines. De plus, l'historiographie extrêmement fragmentée des Aragonais de Naples reproduit les puissants clivages régionaux contemporains entre les entités qui composaient la couronne d'Aragon au XVe siècle. En conséquence, l'entourage d'origine ibérique des rois de Naples n'a fait l'objet que de quelques travaux partiels, adoptant un filtre régional. Au-delà de la cour, il importe aussi de saisir ce groupe dans le contexte de migration massive depuis le royaume d'Aragon vers le le royaume de Naples. Nombreux sont les migrants qui appartiennent aux élites administratives ou marchandes ; ils ont des liens forts avec l'institution domestique, comme le révèle l'étude des réseaux sociaux dans lesquels ils sont insérés. Mais d'autres individus, d'origine sociale plus modeste, affluent également à Naples à partir de la conquête du Magnanime.L'arrivée à Naples et l'installation en ville des officiers curiaux et de ceux qui arrivent dans le sillage du roi et de ses armées pose la question de leur insertion en ville et dans la société politique de la capitale italienne. La migration au service du prince est-elle constitutive d'une quelconque solidarité ou identité ? Selon quelles modalités ces élites migrantes tissent-elles des relations avec les Napolitains ? On constate que le roi incarne une figure médiatrice indispensable au dialogue entre les différentes composantes politiques et sociale de la capitale, tandis que les Catalans accèdent difficilement à la citoyenneté. Ils sont regroupés dans les quartiers bas de la ville, en dehors des circonscriptions administratives disposant d'une représentation politique.L'enquête mobilise des sources diverses : documentation normative inédite, chroniques, production des humanistes stipendiés par le Magnanime, correspondances d'ambassadeurs et registres de la chancellerie conservés à l'Archivo de la Corona de Aragón à Barcelone. La démarche fondamentale de ce travail réside dans le repérage des individus concernés, selon les principes éprouvés de la prosopographie. L'analyse diachronique des données obtenues permet d'apporter des éléments significatifs à l'histoire du premier roi aragonais de Naples, et au règne contesté de son successeur Ferrante. Cette étude sociale et institutionnelle révise en profondeur les approches locales marquant habituellement l'historiographie de la couronne d'Aragon et de Naples, en révélant les usages politiques et militaires de la société curiale, combien la culture politique aragonaise influe sur la pratique du nouveau roi et le tournant démographique et économique que cette période a représenté pour la capitale méridionale. / This PhD dissertation focuses on institutional and social aspects of a 15th century court, the court of Alfonso the Magnanimous, king of Aragon and Naples, between 1416 and 1458. The household of Aragon's kings regulated by court ordinances, the last ones being promulgated in 1344. Since this date, a change of dynasty and the conquest of the Kingdom of Naples has deeply affected the institutional structure of the court and the government's practices chosen by King Alfonso. Moreover, there are no longer court ordinances, and consequently, its structure has been neglected by historical research. In order to fill this gap, this dissertation studies the royal household using documentation issued by the royal chancellery, which provides useful data, showing how the Aragonese household is also the beating heart of the royal administration. As Pietro Corrao described it, the Aragonese household is an efficient “household system of government”.After the conquest of southern Italy, their Italians contemporaries consider the royal officers who came with king Alphonso as a hole (they call them “the Catalans”), but an in-depth study shows that they come from different regions and social background. Their massive arrival in Naples after many years of war for the kingdom caused tensions and xenophobia among the Italians. The royal officers settled down in the harbour neighbourhood, under the royal jurisdiction, whereas the Neapolitan nobility and people lives in the upper city, under the city's jurisdiction. This social and political gap leave its mark upon the failed process of urban integration of the newcomers. However, Alfonso uses his capital city as his favourite stage in order to show himself as an up to date Renaissance king, and display many ceremonial events. His antiquity-inspired triumph is the most famous example of this practice.Career analysis applied to Aragonese officials underlines how they had poor futures prospects in the household hierarchy, but also real opportunities to obtain financial reward and above all a very protective legal status. Indeed every member of Alfonso's household enjoys the legal privilege of being under the seneschal's jurisdiction only. The king may choose to additionally grand this privilege to anyone, through the titles of “counsellors” and “familiars”, the later title being lesser than the first.Since the destruction of the medieval archives in Naples during World War II, many of the sources of this work are from Spanish archives that hold Aragonese royal documents, mainly in Barcelona and Valencia. The ancient humanistic historiography about king Alfonso and letters from diplomatic envoys sent in Naples also provided many information, that have been analysed using prosopographical methods. This data supplies many new facts and allows social analysis, which both contribute to deepen our understanding of the history of the Crown of Aragon and the Kingdom of Naples.

O trabalho foi conduzido nos municípios de Figueirópolis D’Oeste e Lambari D’Oeste com clones procedentes de Perlis, Malásia, e de Ilhas Salomão, e plantas seminais da região de estudo. Os tratamentos foram estruturados em delineamento em blocos casualizados, com medição da circunferência à altura do peito, das alturas comercial e total em parcelas permanentes aos seis e sete anos de idade. Complementarmente, foi feita a cubagem rigorosa, a análise de tronco e quantificada a frequência de copa quebrada. Para o conjunto total de dados e separados por copa quebrada e copa sem danos, foram testados modelos para relação hipsométrica. Com os dados coletados foi simulado o desbaste seletivo na intensidade de 40% das árvores, com determinação dos volumes, incrementos em altura, DAP e volume do povoamento, além do volume extraído pelo do desbaste. Em ambas regiões, os clones foram mais afetados por danos nas copas em relação às plantas seminais. Os danos nas copas afetam a relação hipsométrica e os modelos testados não se adequam para estimar a altura. Em Lambari D’Oeste, para os clones 62 e 68 e plantas seminais, o comprimento médio do dano nas copas ao sexto ano, foi maior que o incremento médio registrado ao sétimo ano. Em ambas regiões, o clone 61 se destacou pelo volume estimado para o desbaste e em Lambari D’Oeste o clone 62 foi estatisticamente igual ao 61. Em Figueirópolis D’Oeste, os clones de Perlis foram superiores aos de Ilhas Salomão e, em ambas regiões o menor volume de desbaste foi produzido pelas plantas seminais. / The objective of this research was evaluate the development of clonal and seminal plants of Teak associated with crown damage intensities in two regions in southwest Mato Grosso. The study was conduct in Figueirópolis D’Oeste and Lambari D’Oeste with clones proceeding from Perlis, Malaysia and Solomon Islands and seminal plants from studies refions. Treatments were structured in a randomized block design, with measuring circumference at breast height, commercial and total heights in permanent plots to six and seven years old. In addition, the cubed, the stem analysis and quantified the frequency of broken cup have been made. For the full set of data and separated by broken crown and crown without damage, models were tested for relative hipsometric. With collected data were simulated selective thinning 40% intensity of the trees, determinating volumes, increases in height, CBH and plantation volume, in addition the volume extracted by the thinning. In both regions, the clones were more affected by crown damage in relation to seminal plants. The crown damage affects the hypsometric relation and tested models are not suitable to estimate the height. In Lambari D'Oeste, for clones 62 and 68 and seminal plants, the average length of crown damage to the sixth year, was higher than the average increase recorded in the seventh year. In both regions, the clone 61 stood out for the estimated thinning volume and Lambari D'Oeste clone 62 was statistically equal to 61. In Figueirópolis D'Oeste, clones of Perlis were higher than in Solomon Islands, and both regions the least volume of thinning was produced by the seminal plants.

Strategie podnikání v oděvním průmyslu / The strategy of business in clothing industry

ŠALAMOUN, Jan January 2008 (has links)
I directed my project at strategic development in textile industry. I worked the project at an example of the company Prima Moda, s. r. o., which has headquarters in Cesky Krumlov. The textile industry can not compete with other branches. Although nowadays the textile industry has automated production already, people have to work by hands. There are high wage cost. It caused, that in developed states the companies canceled production and they transferred it to Eastern Europe.

Sledování výskytu rzí u vybraných druhů trav a jejich vliv na pícninářskou hodnotu / Monitoring of rust in selected grass species and their impact on the value of fodder.

HŘÍDELOVÁ, Lenka January 2011 (has links)
The aim of the thesis is evaluation of occurence of rusts on the selected types of grass, their specific diagnosis and valorization of their influence on the important agricultural qualities. The experiment was carried out in a cooperation with SS Větrov. In a two-year period (in 2009 and 2010) the samples of infested plants, which were subsequently evaluated microscopically, were taken. The ascertained results were processed through the Kruskal-Wallis test and the Independent Group T-Test. In 2009 and 2010 the occurrence of stem rust on the tested types of grass was significantly higher than occurence of crown rust. From the total number of 513 tests stem rust was found in 353 cases, whereas crown rust was found only in 103 cases. In 27 samples the occurrence of both types of rusts was found and there was no occurence found on the rest of the plants. The results show that in our climatic conditions stem rust becomes the most frequent pathogen which causes rustiness of grass. In 2010 the results of turf experiments proved that the selection of genotype of perenne reygrass with a lower infestation by stem rust had a positive impact on health conditions and better appearance of the offspring of the selected plans. Effectivenes of selection was confirmed. Among the tested materials there were chosen very predisposed genotypes which could be useful as the infectious material in the planned greenhouse tests for the resistance against rusts. Currently, we have also been abble to recognize the genotypes which are relatively resistant against particular rusts. If their resistance is confirmed in the following period, they might be used as donors of resistance in xenogamy and as immune standards in tests. The introduced results from the first stage of cooperation are only preliminary and it will be necessary to verify them at the following stages.

Estudo químico e morfológico da broca-da-coroa-foliar eupalamides cyparissias (Fabricius, 1776) (Lepidoptera: castniidae) de arecáceas / Chemical and morphological study of the palm boree, eupalamides cyparissias (Fabricius, 1776) (Lepidoptera: castniidae) from arecáceas

Costa, Dannielle de Lima 31 August 2015 (has links)
The Castniidae family is a group of Pantropical insects with about 150 species widely distributed mainly in the Malay Peninsula, Australia, South America and Central America. The caterpillars of species in this family are borer of cultures of the families Arecaceae, Bromeliaceae, Musaceae, Heliconiaceae, Orchidaceae and Poaceae. Among the species of pests Castniidae family is the borer crown leaf Eupalamides cyparissias Fab. (Lepidoptera: Castniidae), a major pest of palm trees in the Amazon region of Brazil, Ecuador, Colombia, Peru, Venezuela and Northern Panama. The damages are associated with Cocos nucifera L. (Arecales: Arecaceae) (coconut plants) and Elaeis guineensis Jacq. (Arecales: Arecaceae) (oil palm), major crops of economic importance to the state of Pará. This study aimed to observe the E. cyparissias behavior, identify glandular cells in the female ovipositors, distinguish the types of sensilla in the antennae of males and females and investigate the presence of sex pheromones in both sexes. Behavioral observations were carried out in laboratory and palm oil crops in the municipality of Moju, Pará. Histological sections of ovipositors were analyzed in light microscope (Olympus BX41). The antennas were analyzed by Scanning Electron Microscopy (SEM) using a Shimadzu, Model SSX-550 Superscan. For preparation of extracts of front and rear wings of male and female, ovipositor and male sexual organ, adults with 24 and 48 hours of age were used. For each pair of wings 300 uL of hexane (distilled HPLC grade) was used and each male sexual organ or female ovipositor 100 uL was used the same solvent, for 20 minutes, then the supernatant was transferred to a 2 ml vial. Evaluation of the bioactivity of the extracts was performed on GC-EAD and the separation and identification of compounds by GC and GC-MS. Field observations confirm that enabled moths in palm plantations in Pará are quite active in crepuscular time between 6:00 and 7:30 am and between 18:30 and 19:30 pm. Characteristic behaviors courtship as exposure of the ovipositor, clásperes exposure, ovipositor exposure and beating of wings, walk flapping, abdominal movements, guided walk to the opposite sex, antennation and contact have been observed. Histological analysis identified glandular cells located near the cuticle on the dorsal proximal region of the ovipositor. In the antennae of male and female five types of sensilla were observed: trichodea, chaetica, squamiformia, coeloconica, and auricillica. Characteristic behaviors observed and morphological structures allow us to infer chemicals mediating the communication between these insects. The specific compounds males were identified 7,11-hexadecadienal, 7,11-hexadecadien-1-ol, espringene, geranyl linalool and geranyl geraniol. Female specific compounds were identified α-coapaene, trans-caryophyllene, 1-hexadecanol, 9-Hexadecenoic acid, octadecyl ester and Hexadecanoic acid, octadecyl ester. GC-EAD analysis revealed female antenna activity for geranyl geraniol compounds, nonacosane and β-sitosterol present in the extracts of the rear wing of males. / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / A família Castniidae é um grupo de insetos com cerca de 150 espécies, e distribui-se na Península Malaia, Austrália, América do Sul e América Central. As lagartas de espécies desta família são brocas de culturas das famílias Arecaceae, Bromeliaceae, Musaceae, Heliconiaceae, Orchidaceae e Poaceae. Dentre as espécies-pragas da família Castniidae está a broca-da-coroa-foliar, Eupalamides cyparissias (Fabricius, 1776) (Lepidoptera: Castniidae), uma importante praga de palmeiras da região Amazônica do Brasil, Equador, Colômbia, Peru, Venezuela e norte do Panamá. Os prejuízos mais evidentes estão associados às plantas de Cocos nucifera L. (Arecales: Arecaceae) (coqueiro) e Elaeis guineensis Jacq. (Arecales: Arecaceae) (dendezeiro), principais culturas de importância econômica para o estado do Pará. Este trabalho teve por objetivo observar o comportamento de E. cyparissias, identificar células glandulares nos ovipositores de fêmeas, distinguir os tipos de sensilas nas antenas de machos e fêmeas e investigar a presença de feromônios sexuais em ambos os sexos. As observações comportamentais foram realizadas em laboratório e em culturas de dendê no município de Moju, Pará. Os cortes histológicos dos ovipositores foram analisados em microscópio de luz (Olympus, BX41). As antenas foram analisadas por microscopia eletrônica de varredura (MEV) utilizando-se microscópio Shimadzu, modelo SSX-550 Superscan. Para preparação dos extratos das asas anterior e posterior de machos e fêmeas, do ovipositor e do órgão sexual dos machos foram utilizados adultos com 24 e 48 horas de idade. Para cada par de asas foi utilizado 300 μL de hexano (grau HPLC destilado) e para cada órgão sexual do macho ou ovipositor da fêmea utilizou-se 100 μL do mesmo solvente, permanecendo por 20 minutos, em seguida o sobrenadante foi transferido para um vidro de 2 mL. A avaliação da bioatividade dos extratos foi realizada por cromatografia gasosa acoplada ao detector eletroantenográfico (CG-EAD) e a separação e identificação dos compostos através do cromatógrafo gasoso (CG) e cromatografia gasosa acoplado à espectrometria de massas (CG-EM). Observações de campo permitiram confirmar que mariposas em plantios de dendê no Pará são bastante ativas em horário crepuscular entre as 6:00 h e 7:30 h e entre as 18:30 h e 19:30 h. Comportamentos característicos de corte como exposição do ovipositor, exposição de clásperes, exposição do ovipositor e bater das asas, caminhar batendo as asas, movimentos abdominais, caminhada orientada ao sexo oposto, antenação e contato foram observados. A análise histológica permitiu identificar células glandulares localizadas próximas a cutícula na região proximal dorsal do ovipositor. Nas antenas de machos e fêmeas cinco tipos de sensilas foram observadas: tricóide, caética, esquamiforme, coelocônica e auricílica. Comportamentos característicos observados e as estruturas morfológicas permitem inferir substâncias químicas mediando a comunicação entre esses insetos. Os compostos específicos de machos identificados foram, 7,11-hexadecadienal, 7,11-hexadecadien-1-ol, espringeno, geranil linalol e geranil geraniol. Como compostos específicos de fêmeas foram identificados α-coapaeno, trans-cariofileno, 1-hexadecanol, 9-hexadecenoato de octadecila e hexadecanoato de octadecila. Análise de CG-EAD revelou atividade antenográfica da antena da fêmea frente aos compostos geranil geraniol, nonacosano e β-sitosterol presentes nos extratos da asa posterior dos machos.

Avaliação da deformação do intermediário e região peri-implantar em função da carga aplicada em coroas unitárias implantossuportadas parafusadas / Evaluation of the deformation in the abutment and peri-implant region according to the load applied in screwed implant-supported single crowns

Max Laurent Albarracín 30 May 2011 (has links)
As coroas unitárias metalocerámicas implantossuportadas são amplamente utilizadas na reabilitação de pacientes desdentados. O comportamento mecânico destas coroas é muito importante para entender o processo de transmissão de forças mastigatórias e suas reações no intermediário e na estrutura óssea peri-implantar, mas estes processos ainda não estão totalmente compreendidos. O objetivo deste trabalho foi verificar a deformação gerada no intermediário e no osso peri-implantar de coroas unitárias implantossuportadas após aplicação de carga. Foi utilizado um modelo mestre de poliuretano, simulando o osso mandibular, com um implante hexágono externo de 3,75mm x13 mm de comprimento, no qual foi fixado um intermediário multi-unit (Nobel Biocare, Göteborg, Sweden). O trabalho apresentou 3 grupos com quatro corpos de prova cada, divididos de acordo com o tipo de cilindro e liga de fundição (Cilindro de ouro sobrefundidos com a liga de PdAg, cilindro de CoCr usinado sobrefundidos com a liga de NiCoCr, cilindro de acrílico fundido com a liga de NiCoCr ). Cada corpo de prova foi submetido cinco vezes a aplicação de carga axial de 300N em uma máquina de ensaio universal. A força foi aplicada no centro da oclusal de cada coroa. Foram realizadas leituras das deformações geradas no intermediário e no poliuretano com o uso de extensômetros lineares elétricos os quais foram colados em três faces do intermediário e nas superfícies mesial, vestibular, distal e lingual do osso simulado ao redor do implante. Os dados obtidos foram submetidos a análise de variância (ANOVA) e teste de Tukey (p<0,05). Os resultados do estudo demonstraram que a utilização dos três tipos de cilindro não alteram o resultado final de distribuição de tensão no intermediário após o carregamento. Adicionalmente as coroas confeccionadas com cilindro de CoCr usinado, tiveram o comportamento mais estável com relação a uniformidade na distribuição das tensões no intermediário e no osso simulado quando comparados com os outros dois grupos (cilindros de Au e Calcinável). / The metal-ceramic crowns implant-supported are widely used in the rehabilitation of edentulous patients. The mechanical behavior of these crowns is very important to understand the process of transmission of masticatory forces and their reactions at abutment and peri-implant bone structure, but these processes are not fully understood yet. The aim of this study was to verify the deformation in the abutment and peri-implant bone in implant-supported single crowns after load application. Was used a master model of polyurethane simulating the jawbone with an external hexagon implant of 3.75 mm of diameter and 13 mm of length, which was fixed a multi-unit abutment (Nobel Biocare, Göteborg, Sweden). The study presented three groups with four samples each, divided according to type of cylinder and casting alloy (gold cylinder smelting with the PdAg alloy, CoCr cylinder machined cast-on with the league NiCoCr, cast acrylic cylinder with alloy NiCoCr). Each sample was subjected to five times the application of vertical load of 300N on a universal testing machine. The force was applied in the center of the occlusal surface of each crown. Readings were taken of the deformations generated in the abutment and polyurethane with the use of strain gages which were glued on three sides of the abutment and mesial, buccal, lingual and distal surfaces of simulated bone around the implant. The datas were submitted to ANOVA and Tukey test (p<0.05). The study results demonstrated that the use of three types of cylinder does not change the final result of stress distribution in the intermediate after axial loading. Additionally crowns made with machined cylinder CoCr, had more stable with respect to uniform distribution of stresses in the intermediate and the simulated bone when compared with the other two groups (Au and burnout cylinders).

Dois implantes hexágono externo - com 3,75 mm de diâmetro - foram posicionados, com o auxílio de um paralelômetro fresador (1000N; Bio-art), na posição de segundo pré-molar e segundo molar num troquel de resina acrílica, de maneira a ficarem parcialmente submersos na resina expondo apenas suas plataformas de adaptação. Foram confeccionados 10 troqueis de resina acrílica (n=10). A partir de cada troquel foi obtida, pelo método de fundição da cera perdida, uma infraestrutura implanto-retida utilizando-se dois cilindros calcináveis tipo UCLA. A amostra foi submetida à força de torque de seus parafusos de fixação a 20 Ncm, registrada por meio de um torquímetro digital de precisão (Torque Meter TQ-8800; Lutron), e reapertados após 10 minutos. A força de destorque foi registrada após 24 horas do torque inicial. A resistência ao destorque foi analisada após fundição da estrutura protética e simulação dos três ciclos de cocção da porcelana (opaco dentina e glaze). Foram obtidas médias de destorque para cada estrutura nas distintas etapas de avaliação no estudo. Os dados foram analisados estatisticamente pelos testes ANOVA one-way e Bonferroni, com nível de significância de 5% (p<0,05). Os valores das médias da força de destorque dos parafusos por fase foram 13,95 ± 1,12 Ncm para pós-fundição, 15,20 ± 1,18 Ncm para ciclo Opaco, 15,85 ± 1,13 Ncm para ciclo Dentina e 16,80 ± 1,03 Ncm para o glaze. A força de destorque dos parafusos após a fundição foi significativamente menor do que a obtida para os grupos que simularam o ciclo de cocção da porcelana (p<0,05). Entre as fases de simulação dos ciclos cerâmicos, observou-se maior valor da força de destorque para o glaze (p<0,05), não sendo observadas diferenças estatisticamente significantes entre as fases opaco e dentina (p>0,05). Foi possível verificar que os ciclos de cocção da porcelana influenciam a resistência ao destorque em parafusos de estruturas metálicas implanto-retidas fundidas em níquel-cromo (Ni-Cr). Observou-se que os valores de destorque aumentaram gradativamente com cada ciclo de cocção da porcelana / Abstract: This study evaluated the resistance to detorque of screws from implant-retained metal structures cast in nickel-chromium (Ni-Cr) after metal casting and simulation of porcelain firing cycle. Two external hex implants - with 3.75 mm diameters - were placed with the help of a parallelometer cutter (1000N; Bio-art), in the position of second premolar and second molar in acrylic resin die, so as to be partially submerged in the resin exposing only their platforms for adaptation. Thereupon, 10 dies were made with acrylic resin (n= 10). An implant-retained infrastructure from each die was obtained by the method of lost wax casting, using two UCLA cylinders. The sample of acrylic structures were subjected to 20 Ncm of torque to its fixing screws registered by means of a precision digital torque wrench (Torque Meter TQ-8800; Lutron) and retightened after 10 minutes. The measure of detorque was recorded 24 hours after the initial torque. The detorque resistance was analyzed after denture casting, followed by the simulation of porcelain firing cycles (opaque, dentin and glaze). Detorque averages were obtained for each structure at different stages of evaluation in this study. Data was statistically analyzed by one-way ANOVA and Bonferroni tests, at 5% significance level (p>0.05). We performed necessary statistical tests. The mean detorque force of the screws per phase were 13.95 ± 1.12 Ncm for post-casting; 15.20 ± 1.18 Ncm for cycle opaque; 15.85 ± 1.13 Ncm for cycle dentin; and 16.80 ± 1.03 Ncm for glazing. The screw's post-casting detorque resistance was significantly lower than that observed for the groups simulating porcelain firing cycles (p<0.05). Among groups simulating ceramic's cycles, the highest detorque resistance was observed for glaze group (p<0.05), with no significant statistical differences among opaque and dentin groups (p>0.05). It was possible that the porcelain firing cycle influenced detorque resistance of screws in implant-retained metal structures cast in nickel-chromium (Ni-Cr). It was observed that detorque values gradually increased after each porcelain firing cycle / Doutorado / Protese Dental / Doutor em Clínica Odontológica

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / This work aimed to evaluate the morphology and describe the growth of competing and free individual trees of Cordia trichotoma (Vell.) Arráb. ex Steud. The study of free from competition trees was held in the Central region of the state of Rio Grande do Sul, in the cities of Santa Maria and Silveira Martins, and trees under competition were measured in the Campo de Instrução do Ministério do Exército of Santa Maria - CISM and also in Silveira Martins. Competing and free trees larger than 5 centimeters of dbh were numbered and its dendrometric, morphometric and qualitative were measured. The increment data of the last 4 years was obtained from two increment cores collected using Pressler borer. Competition between trees in the forest was calculated based on the number of trees per hectare obtained from the methodologies of Spurr, Bitterlich and Prodan. The louro-pardo trees growing free of competition, has diameter at breast height, crown diameter and the salience index similar to the developed under competition. Under competition, this species invests more in total height, commercial height and height of the crown, however, has less crown length, lower crown percentage and index scope. The louros growing free of competition have periodic annual diameter increment (IPAd) and basal area (IPAg) significantly higher than those under competition. The IPAg this species of free of tree competition can be predicted by dbh, crown factor (fac) and crown density (dec) by two different models, but the model that best fits the data was: IPAg = 0.6665. and 0.0725. (fac.dec). dbh, which considers the fac and dec as discrete variables to determine the slope. The IPAg of louro-pardo under competition can be predicted by the estimated increment from free of competition trees and subtracting the estimated difference between the increments of louros under and free of competition: IPAg = [(0,6665 e 0,0725. (fac.dec) . dap)] [562,28. (N(GBit))-0,585]. The model ln IPAg = 0,5456 . ln dap + 0,1412 . (fac . dec) - 0,00008905 . N(GBit) which has no relationship to the previous model can be used as well, to estimate the increment for louro-pardo under competition, with some advantages over the previous one. / Este trabalho teve como objetivo avaliar a morfometria e descrever o incremento de árvores individuais livres e em competição de Cordia Trichotoma (Vell.) Arráb. ex Steud. O estudo das árvores livres de competição foi realizado na região Central do estado do Rio Grande do Sul, nas cidades de Santa Maria e Silveira Martins e as árvores sob concorrência foram mensuradas no Campo de Instrução do Ministério do Exército de Santa Maria CISM e também em Silveira Martins. Para cada árvore livre e sob competição, foram numeradas as que possuíam dap igual ou superior a 5 cm, e medidas suas variáveis dendrométricas, morfométricas e qualitativas. Os dados de incremento dos últimos 4 anos foram obtidos pela análise de duas baguetas, coletados com a utilização do trado de Pressler. Para a determinação da concorrência entre as árvores na floresta, foi calculado o número de árvores por hectare baseados nas metodologias de Spurr, Bitterlich e Prodan. O louro-pardo quando cresceu livre de competição, apresentou diâmetro a altura do peito (dap), diâmetro de copa e índice de saliência semelhante ao que se desenvolveu em competição. Quando sob competição, esta espécie investiu mais em altura total, altura comercial, altura de início da copa, porém, apresentou menor comprimento de copa, percentagem de copa e índice de abrangência. Os louros quando cresceram livres de competição apresentaram incremento periódico anual em diâmetro (IPAd) e em área basal (IPAg) significativamente superiores quando comparados aos sob competição. O IPAg desta espécie livre de competição pode ser predito pelo dap, pelo fator de copa (fac) e densidade de copa (dec) a partir de dois modelos distintos sendo que o modelo que apresentou melhores ajustes foi: IPAg = 0,6665 . e 0,0725.(fac.dec) . dap pelo qual considera o fac e dec como variáveis discretas para determinar o coeficiente angular. O IPAg do louro-pardo sob competição pode ser predito pela estimativa de incremento que ele atinge quando cresce livre de competição subtraído pela estimativa da diferença de incrementos entre os louros livres e sob competição: IPAg = [(0,6665 e 0,0725. (fac.dec) . dap)] [562,28. (N(GBit))-0,585]. O modelo ln IPAg = 0,5456 . ln dap + 0,1412 . (fac . dec) - 0,00008905 . N(GBit) pelo qual não tem relação com o incremento das árvores livres também pode ser utilizado para a estimativa do incremento dos louros sob competição, com algumas vantagens em relação ao anterior.

Ärm och ärmhåls-konstruktioner i trikå : En undersökning i passformsproblem på trikåplagg med en förlängd axel

Eriksson, Emelie January 2017 (has links)
Syftet med studien är att försöka lösa passformsproblem på trikåmodeller till dam som har en förlängd axel. Studien skrivs i samarbete med ett stort svenskt klädföretag och undersöker ett problem som företaget själva har identifierat. Problemet gäller passformen på några av företagets trikåmodeller till dam som alla har en förlängd axel och en lösare passform. Passformsproblemen som trikåmodellerna upplevs ha uppstår vid just axeln, ärmhålet och överärmsvidden. Inom forskning och litteratur saknas det information kring passformsproblem och åtgärder vid konstruktion av trikåplagg med en förlängd axel. I dagsläget har inte företaget tid att själva testa och utveckla trikåmodellerna och studien har därför fokuserat på att försöka lösa problemet med passformen åt dem. För att uppnå syftet har en experimentell metod använts. Denna har utförts via digital mönsterkonstruktion, uppsömnad av provplagg och verifierats genom avprovningar på provpersoner och på provdocka. Resultatet av studien visar att en medel- till hög ärmkulle behövs till plagg med en förlängd axel för att uppnå en god passform på ärmen och kring ärmhålet. / The purpose of the study is to try to solve fit problems on women’s jersey models with a dropped shoulder. The study is written in collaboration with a large Swedish clothing company and investigates a problem that the company itself has identified. The problem concerns the fit of some of the company's jersey sweaters for ladies, each with a dropped shoulder and a looser fit. The fit problems that the jersey models are having occurred at the shoulder, the armhole and bicep. In research and literature there is no information about fitting problems and how to adjust the construction of jersey garments with a dropped shoulder. At present, the company does not have time to test and develop the jersey models, and the study has therefore focused on trying to solve the problem of the fit for them. To achieve the aim, an experimental method has been used. This has been done through CAD-based pattern construction, sewing test prototypes and verified by fittings on human fitting models and on a dummy. The result of the study shows that a medium to high sleeve crown is needed for clothes with an extended shoulder to achieve good fit on the sleeve and around the armhole.

What is the equilibrium exchange rate of the Czech koruna? / What is the equilibrium exchange rate of the Czech koruna?

Jančovič, Pavel January 2017 (has links)
The aim of this thesis is to estimate bilateral equilibrium exchange rate of the Czech koruna relative to Euro and to determine if the Czech currency is undervalued or overvalued relative to the market equilibrium. We employ fundamental (FEER) and behavioral (BEER) equilibrium exchange rate models, which enables to measure the currency position relative to the market rate. To tackle the uncertainty of the implied equilibrium exchange rates that differ among alternative specifications of the models, we aggregate the estimates via principal components analysis. The perception on the market is that Czech koruna is undervalued, since the intervention regime imposed by the Czech National Bank in the 2013, was defending the exchange rate floor of 27 Czech korunas to Euro. Then, we extend conventional specifications of BEER models for variables representing exchange rate interventions and forward rates offered on the market because both can have protracted effects not only on spot rates but on adjustment towards long-term equilibrium as well. The original models with fundamental factors show equilibrium exchange rate near to 25 CZK/EUR. However, extended models with interventions show higher equilibrium exchange rate, near to 27 CZK/EUR. Thus, there is possibility of slow adjustment near to the...
