A study of Aldred's multiple glosses to the Lindisfarne Gospels

Aldred, the glossator of the Lindisfarne Gospels, presents himself as carefully rendering the Latin lemmata in front of him, in terms of both their internal structure and meaning. His work includes a very high number of multiple glosses, which often attempt to clarify the polysemous character of a lemma or to provide additional information. This paper explores the multiple glosses including different lexemes which Aldred added to lexical lemmata in Mark’s Gospel in an attempt to establish whether there is any correlation between Aldred’s ordering practices and the frequency with which he used the interpretamenta to render those lemmata. The results of the study show some preference for placing the interpretamentum which most commonly renders the Latin lemma in first position, although Aldred’s practice is not fully consistent.

On affirmation and becoming : a Deleuzian reading of Nietzsche's critique of nihilism

The main thrust of this thesis is the re-exploration of Friedrich Nietzsche's "critique of nihilism" through the lenses of Gilles Deleuze. A Deleuzian reading of Nietzsche is motivated by a post-deconstrnctive style of interpretation, inasmuch as Deleuze goes beyond, or in between, henneneutics and deconstrnction. Deleuze's post-deconstrnctive reading of Nietzsche is, however, only secondary to the main aim of this thesis. The primary thrust of this study is the critique of a way of thinking characterized by Nietzsche as nihilistic. Therefore, it should be noted that this study is not about Deleuze's reading per se; rather, it is an appraisal of Nietzsche's "critique of nihilism" using Deleuze's experimental reading. We will accrue Nietzsche's critique and Deleuze's post-deconstrnctive reading in order to appraise Nietzsche's critique itself. Insofar as we have underscored Deleuze's purported experimentation of Nietzschean themes, this study is also an experiment in itself. Through this experimentation, we will find out whether it is possible to partly gloss Nietzsche's critique of nihilism through Deleuzian phraseology. Far from presenting a mere exposition of Nietzsche's text, we are, rather, re-reading, that is, re-evaluating Nietzsche's critique of nihilism through Deleuze's experimentation. This is our way of thinking with Nietzsche. Nihilism is the central problem upon which Nietzsche's philosophical musings are directed; he deems nihilism as a cultural experience and, as such, a phenomenon to be reckoned with. In our reconstruction of Nietzsche's critique of nihilism, we locate two related elements which constitute the structure of the prescription of a cure, Le., the ethics of affirmation and the ontology of becoming. Appraising Nietzsche's ethics and ontology amounts to clarifying what Deleuze thinks as the movement from the "dogmatic image of thought" to the "new image of thought." Through this new image of thought, Deleuze makes sense of a Nietzschean counterculture which is a perspective that resists traditional or representational metaphysics. Deleuze takes the reversal of Platonism or the transmutation of values to be the point of departure. We have to, according to Deleuze, abandon our old image of the world in order to free ourselves from the obscurantism of foundationalist or essentialist thinking. It is only through the transmutation of values that we can make sense of Nietzsche's ethics of affirmation and ontology of becoming. We have to think of Nietzsche's ethics as an "ethics" and not a moral philosophy, and we have to think of his ontology as 1/ ontology" and not as metaphysics. Through Deleuze, we are able to avoid reading Nietzsche as a moral philosopher and metaphysician. Rather, we are able to read Nietzsche as one espousing an ethical imperative through the thought of the eternal return and one advocating a theory of existence based on an immanent, as opposed to transcendent, image of the world.

L'evolució dels models de turisme litoral: el Regne Unit, la Costa brava i Cuba

La tesi es centra en una anàlisi prèvia de les implicacions de la teoria del cicle de vida aplicada a les destinacions turístiques pel geògraf canadenc Richard W. Butler (1982) i en un estudi del significat de l'aparició del postmodernisme i les seves repercussions en el turisme, a la vegada que es resegueix la història que ha fet possible l'aparició del turisme massificat de sol i platja. Tot això és la base teòrica imprescindible per poder estudiar empíricament les destinacions de Saltburn (Regne Unit), l'Estartit (Costa Brava) i Cayo Coco (Cuba), utilitzant el cicle de vida per escriure la seva història i veure les polítiques de desenvolupament i regeneració turística que s'han seguit i si aquestes es poden qualificar de postfordistes. La principal conclusió és que el concepte del cicle de vida es limita a ser una eina de diagnòstic a posteriori. El cicle de vida, com a instrument prescriptiu, no serveix. Es específic per a cada destinació, amb unes etapes i punts d'inflexió que només es poden establir en restrospectiva. El cicle de vida és una eina descriptiva molt útil per entendre l'evolució de les destinacions turístiques i els seus mercats, però vigilant de no caure en falses exploracions o perillosos determinismes.

Biodegradable Films Based on Blends of Gelatin and Poly (Vinyl Alcohol): Effect of PVA Type or Concentration on Some Physical Properties of Films

The aim of this work was to develop biodegradable films based on blends of gelatin and poly (vinyl alcohol) (PVA), without a plasticizer. Firstly, the effect of five types of PVA with different degree of hydrolysis (DH) on the physical properties of films elaborated with blends containing 23.1% PVA was studied. One PVA type was then chosen for the study of the effect of the PVA concentration on the mechanical properties, color, opacity, gloss, and water solubility of the films. The five types of PVA studied allowed for films with different characteristics, but with no direct relationship with the DH of the PVA. Therefore, the PVA Celvol (R) 418 with a DH = 91.8% was chosen for the second part, because they produced films with greater tensile strength. The PVA concentration affected all studied properties of films. These results could be explained by the results of the DSC and FTIR analyses, which showed that some interactions between the gelatin and the PVA occurred depending on the PVA concentration, affecting the crystallinity of the films.

Utvärdering av mätmetoder för att fastställa lackmängden vid offsettryckning on-line

This project has been made in cooperation with Stora Enso Research Centre Falun (Research). Thebackground of the project is that Research has customers who demand a method to measure the quantityof varnish online in offset printing. The aim with the project is to investigate if any test method correlateswith the quantity of varnish and to improve the understanding of the variables in the varnishingunit. The goal with the project is to develop a functional method. Two printing trials have beenperformed. The aim with the first trial was to investigate how different factors in the printer influencedthe quantity of varnish using reduced factoranalysis. The aim of the second trial was to analyse onlya reduced numbers of factors in the varnishing unit. The methods that were used to measure the varnishingquantity are weighing, IR-analysis, gloss, whiteness and brightness. Results from the projectshow that the weighing method does not work in this study due to basis weight variations of the sheets.The results from weighing did not agree with the results from the other methods. On the other handthere is a strong correation between the IR- and the glossmethods.

Copolimeros de propileno-etileno com baixos teores de etileno : estrutura, morfologia e propriedades

A estrutura básica predomínante encontrada em todos os copolímeros foi a de longos blocos de polipropileno cristalizáveis, separados por unidades isoladas de etileno, que atuaram como defeitos cristalínos, reduzindo o grau de cristalínidade, além da perfeição e da espessura dos cristais. O gradual aumento do teor de etileno nas amostras origínais, até aproximadamente5 moI % provocou redução progressiva no comprimento dos blocos de propileno em ambas as frações cristalizável e elastomérica. Acima daquela concentração, o etileno mostrou por principal efeito a elevação do teor de borracha de etileno-propileno(EPR), refletíndo-seem pronunciado aumento da resistência ao impacto dos copolímeros, com pouca alteração do comprimento das seqüências propiJênicas nas frações cristaJizáveJe elastomérica. A estrutura e a morfologia da borracha EPR gerada foram analisadas, observando-se sua excepcional dispersão na fase contínua cristalína. Análise das curvas de fusão por DSC, utilizando-se conceitos cínéticos, demonstrou a existência de uma energia de ativação aparente de fusão, associada à introdução de unidades etilênicas nas cadeias, e relacionada ao processo de fusão dos cristais poliméricos. A redução de cristalínidade das amostras e o aumento de mobilidade de cadeia da fase amorfa para teores crescentes de etileno resultaram em redução da rigidez dos copolímeros. Propriedades ópticas, como "haze" e brilho mostraram-se dependentesdo balanço entre o teor de cristais e o teor de borracha. Um balanço global das propriedades analisadas sugere uma composição ótima para aplicações típicas de copolímeros de propileno-etileno aquela com teores de etileno entre 4 e 6 moI % (aproximadamente 3 -4 % em massa).

A percepção de valor de uma biblioteca médica digital para o embasamento das condutos assistenciais adotadas em um hospital privado no Rio de Janeiro

Este estudo foi desenvolvido em um hospital privado, no Rio de Janeiro, com o intuito de demonstrar o valor de uma biblioteca médica digital, como ferramenta de suporte para fundamentação científica das condutas assistenciais adotadas pela equipe médica, que resultaram em glosas técnicas e perda de faturamento para a instituição. Para isso, por meio do método revisão integrativa, foi coletada a literatura clínica referente às glosas, ocorridas durante o período de janeiro a setembro de 2014, e analisada sob a perspectiva do modelo conceitual apresentado pela Cochrane (LEFEBVRE et al., 2011) que identifica o nível da evidência científica e estabelece o seu grau de recomendação para a prática clínica. Durante a análise de conteúdo, considerando as técnicas propostas por Bardin (1977), foram identificadas as evidências científicas que conferem valor à prática assistencial, conforme proposto pelo modelo conceitual. Além disso, o valor dos itens glosados foi incluído na análise dos resultados, reforçando a tendência do estudo para a validação do modelo conceitual que recomenda a prática clínica baseada em evidências científicas para geração de resultados mais efetivos e de melhor custo/benefício na saúde. Com base nos achados, são discutidas as implicações teóricas e práticas, assim como sugestões para futuros estudos sobre o tema.

Processamento e caracterização de compósitos Poli(METACRILATO DE METILA)/Sílica (PMMA/SiO2)

Currently the search for new materials with properties suitable for specific applications has increased the number of researches that aim to address market needs. The poly (methyl methacrylate) (PMMA) is one of the most important polymers of the family of polyacrylates and polymethacrylates, especially for its unique optical properties and weathering resistance, and exceptional hardness and gloss. The development of polymer composites by the addition of inorganic fillers to the PMMA matrix increases the potential use of this polymer in various fields of application. The most commonly used inorganic fillers are particles of silica (SiO2), modified clays, graphite and carbon nanotubes. The main objective of this work is the development of PMMA/SiO2 composites at different concentrations of SiO2, for new applications as engineering plastics. The composites were produced by extrusion of tubular film, and obtained via solution for application to commercial PMMA plates, and also by injection molding, for improved the abrasion and scratch resistance of PMMA without compromising transparency. The effects of the addition of silica particles in the polymer matrix properties were evaluated by the maximum tensile strength, hardness, abrasion and scratch resistance, in addition to preliminary characterization by torque rheometry and melt flow rate. The results indicated that it is possible to use silica particles in a PMMA matrix, and a higher silica concentration produced an increase of the abrasion and scratch resistance, hardness, and reduced tensile strength

Desenvolvimento e teste de um protótipo de reator de plasma com gaiola catódica rotatória para nitretação em lote de pequenas peças

The technique of ion nitriding, despite being fully consolidated in the industry, has great limitations when applied to the treatment of small parts. This is because effects that occur due to non-uniformity of the electric field, generate localized heating in parts, damaging the uniformity of nitrided layer. In addition, because the samples are treated static parts thereof are untreated. To expand the use of plasma nitriding, this work presents the development, assembly and testing of a prototype plasma reactor with rotatory cathodic cage [patent pending], able to meet these needs, giving the material a uniform treatment and opening doors to industrial scale production. The samples tested with hexagonal nuts are 6.0 mm in diameter, made of stainless steel AISI 304 nitrided at a pressure of 1 mbar in an atmosphere of 20% H2 + 80% N2 for 1 h. After treatment, testing visual inspection, optical microscopy and microhardness were carried out to check the effectiveness of the process for uniformity and hardness of the parts. All samples exhibited uniform color, and matte brownish, unlike the untreated samples, silver color and gloss. The hardness of the surface (top and sides) was 65% and even higher than the original hardness. The nitrided layer showed great uniformity in microstructure and thickness. It is concluded, therefore, that the unit was effective constructed for the purposes for which it was designed

Composite surfaces after finishing and polishing techniques

Purpose: To evaluate the effect of finishing and polishing techniques on surface roughness of resin-based composites (RBCs). Materials and Methods: Forty specimens of each material were cured under Mylar strips and immersed in artificial saliva for 1 wk. Samples were tested with a profilometer to obtain baseline average surface roughness (Ra). Specimens of both RBCs were then finished and polished according to four techniques: (1) Sof-Lex disks; (2) Sof-Lex disks followed by Prisma Gloss; (3) Enhance points; (4) Enhance points followed by Prisma Gloss application. New readings of the roughness pattern were carried out and the difference of post-polishing and baseline values were analyzed. Results: ANOVA test (alpha= 0.05) did not show differences between materials (P= 0.9393) nor interaction effects (P= 0.3094), but significant difference among the finishing/polishing techniques were detected (P= 0.0157). Tukey's test showed that the smoothest surface was obtained when the specimens were treated by Sof-Lex followed by Prosma Gloss polishing paste; and the worst results were obtained after using Enhance points alone.

Effectiveness of surface protection for resin-modified glass-ionomer materials

Objective: the purpose of this study was to evaluate the effectiveness of various surface treatments for resin-modified glass-ionomer restorative materials by determining dye uptake spectrophotometrically. Method and materials: Two hundred twenty-four specimens, 4.1 mm in diameter and 2.0 mm thick, were made of 3 materials: Vitremer, Fuji II LC, and Photac-Fil Aplicap. Specimens were divided into 15 groups. The positive and negative control specimens remained unprotected, while the experimental specimens were protected with Heliobond light-activated bonding resin, Colorama nail varnish, or surface coatings indicated by the manufacturers of the glass-ionomer materials. Finishing Gloss for Vitremer, Fuji Varnish for Fuji II LC, and Ketac Glaze for Photac-Fil. The disks were immersed in 0.05% methylene blue for 24 hours except for the negative control group, which was immersed in deionized water. After 24 hours, the disks were removed, washed, and individually placed in 1 mL of 65% nitric acid for 24 hours. The solutions were centrifuged and the spectrophotometric absorbance was determined at 606 nm. The dye uptake was expressed in micrograms of dye per milliliter, and the results were analyzed with the Kruskal-Wallis test. Results: There were no differences in dye uptake among the 3 resin-modified glass-ionomer restorative materials, however, all of them required surface protection. Conclusion: the best surface protection for the 3 evaluated materials was obtained with Heliobond light-activated bonding resin.

Natural fiber reinforced unsaturated polyester composites - An approach on compression molding

This work has been performed at Tapetes Sao Carlos-Brazil with the cooperation of the DaimlerChrysler Research Center Team in Ulm - Germany. The objective of the present paper is to report the results obtained with natural fiber reinforced unsaturated polyester (UP) composites, concerning surface quality measurements. The fibers that have been chosen for this work were sisal and curaua. The samples were produced by compression molding technique and afterwards submitted to three different tests, namely: a) thermal aging; b) water absorption and c) artificial weathering. The surface parameters measured before and after the tests were gloss, haze, short and long-waviness. The results have shown that after the tests there is a high loss of gloss, a high increase in haze, and a high increase in short and long-waviness as well. Curaua reinforced composites had a slightly better behavior when compared with sisal reinforced composites. The effect of the presence of filler and the addition of thermoplastic polyester (TP) on the material behavior has not been evidently detected. This result shows that the conventional technology/methods applied to UP-Fiberglass systems cannot be transferred to natural fibers without any modification. The fiber-matrix interaction and its response to the presence of additives must be fully understood before a successful processing route can be developed for painted natural fibers reinforced UP.
