Full textINTRODUCTION: Accurate body composition assessment is crucial for determining health consequences due to excess body fat (BF). While several techniques exist there are few that are accurate, non-invasive, fast, and comfortable for subjects. The Three Dimensional (3D) body scanner is a new body composition assessment method that might serve as another option for investigators and practitioners. The purpose of this study was to determine the accuracy of the 3D body scanner at measuring body composition using dual energy x-ray absorptiometry (DXA) and Air displacement plethysmography (Bod Pod) as criterion measures. The 3D body scanner was evaluated on its ability to work with differences in normal versus overweight subjects as determined by BMI. Also, a new prediction equation was created and compared to that of an existing equation used by the 3D body scanner developed by the Department of Defense (DoD).
METHODS: Eighty-Five male subjects (21.70 ± 2.28 yr old; 81.00 ± 12.21 kg; 25.37 ± 3.40 kg/m2) completed all body composition assessment techniques on the same day. Tests preformed included: DXA, Bod Pod, and 3D body scanning. Subjects did not eat or drink 2 hr previous to testing and did not exercise 4 hr previous to testing. Data was analyzed using SPSS version 17.0. Bland-Altmand plots, Pearson correlations, and a oneway ANOVA comparing means were performed. A prediction equation (3D MU) was created using a stepwise regression based on correlation to DXA.
RESULTS: Mean comparison of body composition techniques were as follows: DXA BF 16.30 ± 4.67; Bod Pod 12.17± 7.19; DoD 13.53 ± 6.43; 3D MU 16.49 ± 4.16. 3D MU had a SEE=3.09 over the entire sample compared to DoD SEE=3.67 and Bod Pod SEE=2.45. Although body volumes of Bod Pod and 3D Scanner were highly correlated (r = 0.984; p =0.001), the 3D Scanner underestimated body volume. Improvement in making consistent estimations of head, hand, and feet are necessary for the 3D body scanner to be used for body composition assessment.
CONCLUSION: Although the 3D body scanner shows promise as a method of evaluating BF, more work is needed before it can be considered an acceptable laboratory method of assessment. A 3D MU prediction equation was created that appears to be more accurate for young men than the current DoD equation. 3D body scanning shows potential as a method for determining body composition in overweight subjects.

Igor Stravinsky used a compositional technique that researchers have termed cut-and-paste. During the compositional process, Stravinsky would write notes on carbon paper, then cut the lower parts out to paste them into other sheets of paper with music on them. This paper examines a few key ways this fits into the compositional process for Symphonies of Wind Instruments (1920, rev. 1947). In an original work, Whither No One Knows (a chamber work for flute, clarinet, marimba, piano, violin, viola, and cello) several similar cut-and-paste compositional processes were used. These include melodic cut-and-paste, ostinato creation, layering, rhythmic diminution, and extension. These techniques are illustrated and examined. The full score of Whither No One Knows (2009) is included.

Welding is an essential manufacturing process in industries that require the joining of metal components such as the automotive and aerospace industries. While specialized techniques have developed for many of these industries, the process of welding remains fundamentality the same, and the effectiveness of these processes to securely join metal is always characterized by the material properties of the metal after welding. The tensile test performance of forge welds when made with different iron alloys, forge welding techniques, and fluxes was measured. The alloys used were 1018 steel, A36 steel and wrought iron. The forge welding techniques were the hydraulic press, the power hammer, and hand hammer. The fluxes were borax, fine silica sand, anti-borax, and no flux. Control tensile samples (un-welded) of each alloy, as received, were tested along with annealed samples. All testing was performed with an Instron 5984 Universal Testing Machine with 150kN capacity. The results of the welded alloy tests showed that welded 1018 and A36 steel both had considerably lower strength than their control annealed counterparts, whereas welded wrought iron remained just as strong. The results of the forge welding techniques test showed consistent welded A36 steel strengths across techniques used which may suggest that the effectiveness of particular techniques may be more dependent on experience and practice. The flux results show that silica sand and anti-borax work just as well as, if not better than, borax. Using no flux resulted in failed welding, revealing that achieving successful welds without flux requires more welding experience or a different method than the one performed by the welder of the samples for the present experiment. The results of the control alloys showed that 1018 and A36 steel both had considerably lower strength than their annealed counterparts, whereas wrought iron remained just as strong.

Full textENGLISH ABSTRACT: This study was initialized to introduce capillary electrophoresis (CE) as a useful technique in the analysis of fluid inclusions in quartz. lts advantages are low detection limits for the dissolved ionic content of the fluid, the small amount of sample (1 g or less) for a detailed qualitative and quantitative analysis, and the short time required to obtain results (one run for either cations or anions take approximately 10 minutes). The study area from which quartz veins were selected is situated within the Neoproterozoic Saldania belt. Syn- and post-tectonic S-, 1- and A-type granitoids from the Cape Granite Suite intruded the metamorphosed Malmesbury greywacke and pelites between 550 and 510 Ma. Additional periods of tectonism and metamorphism occurred during Cape Supergroup sedimentation (480 - 400 Ma) as well as Karoo sedimentation and the simultaneous Cape Orogeny (280 -215 Ma). The quartz-biotite±chlorite vems are hosted by Cape Granite as well as Malmesbury sediments. These barren quartz veins are part of two vein sets, one dipping at an angle between 15 and 500 to the S to SE and striking W, similar to Sn-mineralized quartz veins in the SW-cape, while the other is near-vertical and striking W to NW. Except for their orientation, no differences regarding associated minerals, inclusion characteristics or fluid chemistry indicated a difference in origin. Four fluid phases within a temperature range of 160 - 390 °C were identified as being largely late-magmatic and released from the underlying Cape Granite plutons, namely an early 370- 390 °C population, followed by the 310 - 360, 230 - 300 and lastly the 160 - 200 °C populations. Initiation of this fluid system occurred from at least SlOMa, after final granite intrusion, but the age of the final stage is unknown. Renewed fluid circulation occurred during a later period of metamorphism, possibly during the Cape Orogeny. These fluids had temperatures between 240 and 360°C and are of sedimentary origin, most likely released from the Malmesbury metamorphites. The technique of capillary electrophoresis has been evaluated for its application to bulk fluid inclusion analysis, and the crush-leach fluid extraction procedure of Bottrell, et al., (1988) optimized for CE analysis. Contamination factors were identified and minimized or eliminated, where possible. Bulk fluid inclusion chemistry obtained by CE was therefore proved to provide valuable information regarding the various fluid generations as long as inclusion populations are investigated individually to explain and correlate bulk data.
AFRIKAANSE OPSOMMING: Die doel van die studie was om te toon dat die tegniek van kapillêre elektroforese bruikbaar is in die analiese van vloeistofmsluitsels in kwarts. Die voordele van hierdie tegniek is lae deteksie limiete vir die opgeloste ioon inhoud van die vloeistof, die klein monstergrootte (< 1g) wat nodig is vir 'n omvattende kwalitatiewe en kwantitatiewe analise, en die kort tydsduur waarin resultate verkry word ('n katioon of anioon analise vir een monster duur lO minute). Die studie gebied waar kwarts are gemonster is, is binne die Neoproterosoïese Saldania Gordel geleë. Sin- en laat-tektoniese S-, I- en A-tipe graniete van die Kaapse Graniet Suite het die gemetamorfiseerde Malmesbury grouwakke en peliete tussen 550 en 510 Ma binnegedring. Latere periodes van tektonisme en metamorfose het tydens deponering van die Kaap Supergroep (480 - 400 Ma), en die gelyktydige episodes van Karoo sedimentasie en Kaapse Orogenese (280 - 215 Ma) plaasgevind. Die gasheer gesteentes vir die kwarts-biotiet±chloriet are is Kaapse Graniet sowel as Malmesbury sedimente. Hierdie ongemineraliseerde are is deel van twee aarstelsels, nl. een met 'n duik hoek tussen 15 en 50° S tot SO en 'n westelike strekking, soortgelyk aan die Sn- ,.gemineraliseerde are in die SW-Kaap, terwyl die ander stel are feitlik vertikaal is en W tot NW strek. Behalwe vir die verskil in oriëntasie was daar geen aanduiding, wat betref 'n verskil in geassosieerde minerale, vloeistofinsluitsel kenmerke of vloeistof chemie, dat hierdie twee aarstelsels van verskillende oorsprong is nie. Vier vloeistof fases binne 'n temperatuur gebied van 160 - 390 °C en 'n vloeistof saliniteit van 0 - 5.7 gewig % NaC1 ekw. is geïdentifiseer, met 'n laat-magmatiese assosiasie en vrygestel deur die onderliggende Kaapse Graniete. Dit behels 'n vroeë 370 - 390 °C populasie, gevolg deur die 310 - 360, 230 - 300 en laastens die 160 - 200 °C populasies. Inisiasie van hierdie sisteem kon moontlik rondom 510 Ma gelede plaasgevind het, maar die ouderdom van die finale fase is onbekend. Hernude vloeistof sirkulasie het tydens 'n later stadium van metamorfose onstaan, moontlik tydens die Kaapse Orogenese. Hierdie vloeistowwe het temperature tussen 240 en 360 °C en is van sedimentêre oorsprong waar dit moontlik deur metamorfose van die reeds gemetamorfiseerde Malmesbury gesteentes vrygestel is. Die tegniek van kapillêre elektroforese is vir die toepassing daarvan in die analise van vloeistof insluitsels in kwarts geëvalueer, terwyl die vloeistof vrystellingsmetode van Bottrell en Yardley (1988) vir hierdie tegniek geoptimaliseer is. Kontaminasie faktore is geïdentifiseer en verminder of uitgeskakel waar moontlik. Daar is getoon dat die vloeistof chemie, wat verteenwoordigend is van al die insluitsel populasies in 'n monster, wel bruikbaar is t.o.v. afsonderlike vloeistof generasies, solank elke populasie individueel bestudeer is om die omvattende chemiese data te verduidelik en met 'n enkele populasie te korrelleer.

Our approach yields from an analysis of websites contents, from the point of view of their material form and of the complex mediations that emerge among users, the medium and content publishers. The thesis is articulated along the following axes : questioning the nature of the « website object » in its relation to the communication partners ; observation and analysis of the transformations induced by the Web to the conditions of sense production ; observation of the way the transformations of institutional positions and of mediations with respect to the Web productions are expressed. In particular, we investigate the metaphor-based mechanisms that arise involving website designers' strategies, users' practices and medium proprieties

Full textThis study stems from teaching experience and comes as a response to students' questions and errors. It has two main objectives : on the one hand a critical review of existing research on compounds and other complex nominals in English, and on the other hand the application of the theoretical data available in order to help French-speaking students and researchers, who need to communicate (understand, speak and write) in English, namely in the domain of physico-chemical sciences. After a survey of the characteristics of compounds, and an investigation of axamples taken from several corpora, a new morphological classification of binominal compounds is suggested, then the semantic relations between their elements are pointed out. The results are extended to longer nominals, with a particular attention paid to words built from Greek and Latin bases, and acronyms, which abound in the field of sciences. These competing structures : N₂ N₁, N₂'s N₁ and N₁ of N₂ are contrasted, as they are a major source of error among French speakers, especially at the encoding stage. Lastly, an electronic glossary in Excel format including some of the terms of the domain, together with examples of attested sentences, has been developed. One of the future objectives is to transfer the glossary in HTML format in order to make it more available for use in various domains

Full textThe radical changes wich often accompany major technical innovations tend to overshadow the long-term factors which give continuity to industrial activities. The present study looks at the replacement of hot metal photographic techniques in type composition through the case of the lumitype-photon, the first commercially successful second generation phototypesetting machine. An introductory section provides a systematic description of typographic production activities as well as of traditional composing techniques. The invention, development and industrial exploitation of the lumitype-photon are then described and analysed in a global (i. E. Technical, organisational and cultural) context. Technical innovation in the field of typographical production is seen to be strongly influenced by organisational) factors as well as cultural practices. The skills and production organisation which condition the development and industrial implantation of new techniques are themselves dependant on the nature of the raw material of typography (the text) and of its products. In analysing a key period in the history of printing techniques, the author provides a model of technical innovation applicable to other areas of cultural production

Full textThe thesis studies the type-setter's craft in high-volume printing houses. More particularly, it deals with technological change and with professional culture. Its draws upon fieldwork carries out between 1985 and 1993, in three industrial printing-houses in the french provinces. The author examines the transformations brought about by the introduction of photo-composition, considering its impact as much on the work-posts (in terms of task content and flow,and what skills these necessitate), as on the representations and values of the type-setters culture. Also emphasized is the role of work-groups with their specific history and social structure-in acquiring new techniques and updating the trade. The research draws upon earlier work that has dealt with other aspects of this sector relations between printers and makers of equipment, with other aspects of this sector : relations between printed and makers of equipment, and between labor unions and professional training. Observable changes in the workshops are accounted for withen a larger framework of transformations in their environment and overhauls in the community of their profession. This broadening of the field of vision,together with the many returns to the field made possible by the length of the study, show that technological change participates in the dynamics of social construction in the printing trades

Full textIce cores enable reconstruction of past climates, from among others water stable isotopic composition (δ18O, δ17O et δD). On the East Antarctic Plateau, very cold temperature and low accumulation provide the longest ice core records (up to 800 000 years) but embrangle the interpretation of isotopic composition. First, reconstructions of temperature variations from ice core water isotopic composition are based on models used to describe the evolution of the isotopic composition of the vapour and of the condensed phase over the entire water cycle. These models have been developed during the last decades and depend upon precise determinations of isotopic fractionation coefficients associated to each phase transition and upon hypotheses to describe cloud microphysics.During the formation of snowflakes at low temperature, two types of isotopic fractionations need to be taken into account: equilibrium fractionation, associated to the vapour to ice phase transition and kinetic fractionation associated to the difference of diffusivity of the different isotopes. At low temperature, determinations of equilibrium fractionation coefficients present important discrepancies and have never been realised for temperature below -40°C. However, mean annual temperature at Dome C is around -54°C reaching -85°C in winter. For the diffusivities of the different isotopes, they have never been measured at temperature below 10°C. All these gaps result in important uncertainties on the link between isotopic composition and temperature, especially for cold and dry conditions such as encountered on the East Antarctic Plateau.Furthermore, because of the very low amount of precipitation, physical processes affecting the isotopic composition of the snow after the deposition of snowflakes can results in an important contribution to the isotopic budget. In order to estimate the impact of the post-deposition processes on the water vapour isotopic composition, it is necessary to characterise the isotopic fractionation at the snow/atmosphere interface for temperature down to -90°C.In order to improve isotopic paleothermometer performances, it is primordial to study processes affecting snow isotopic composition. Toward this goal, my Ph-D has been at the interface between monitoring of processes affecting isotopes, both in laboratory experiments and field studies, and instrumental development to push the limits of water vapour isotopic composition trace detection. On one hand, new developments in optical feedback frequency stabilisation applied for the first time to water isotopic composition monitoring provide performances beyond any commercial instrument and can be used for thorough processes studies. The laser frequency is stabilised by optical feedback from an ultra-stable cavity to the hertz level. Then, the light is injected in high performances cavity with a sensibility of 10-13 cm-1.Hz-1/2. This enables measuring isotopic composition with a precision below the ppm level.On the other hand, laboratory experiments have supported theories about isotopic fractionation associated to the vapour to ice phase transition and to kinetic fractionation linked to the difference of diffusivities of the different isotopes. Finally, these physical models have been collated to field measurements realised at Dome C in Antarctica, which are among the first water vapour and snow isotopic composition measurements realised inland Antarctica. These measurements show how important is the contribution of the sublimation condensation cycles to the snow isotopic composition budget on the East Antarctic Plateau

Full textThe atmosphere is a complex System in which gaseous, liquid and particulate phases coexist. Indeed, it contains particle in suspension, either solid or liquid, called aerosols. Atmospheric photo-oxidation of volatile organic compounds (VOCs) may lead to the formation of particulate matter, also called secondary organic aerosol (SOA). Hence, SOA is nowadays known to play an important role in the radiative balance, linked to climate change. At a local scale, it also reduces visibility and causes health effects. Because these phenomena are associated to SOA chemistry, it is necessary to include it in atmospheric models in order to better assess SOA climate and health impact. This implies to carry out investigations focused on specific precursors and performed in close to real and controlled conditions. Atmospheric simulation chambers are essential tools to achieve this task. Moreover, to elucidate comprehensive mechanism, SOA chemical composition has to be determined at a molecular level. However, no standard technique for SOA analysis exists. In this context, the aim of this work was to develop such a technique based on supercritical fluid extraction directly coupled to gas chromatography and mass spectrometry technique. After the development phase, this technique has been validated by studding SOA formed from a biogenic VOC precursor and used to study SOA formed from three precursors of different origin. In each case, we managed to identify and quantify some SOA components and propose formation pathways. Thus, this work contributes to a better understanding of SOA formation and evolution pathways in the atmosphere and consequently allows to better assess its effects

Full textIn this PhD thesis, the electrochemical performances of the misfit layered oxide Ca3Co4O9+δ used as a cathode for Solid Oxide Fuel Cell were tentatively optimised by optimisation of the electrode microstructure and composition. Using screen printing as a deposition technique, the Area Specific Resistance was decreased to 0.5 Ωcm2 at 700°C for a composite made of 50% in weight of cerium gadolinium doped oxide and Ca3Co4O9+δ. Spin coating and electro-spray deposition were also tested as promising technique to improve the performances. The impact of partial substitution of the calcium site on the electrochemical performances was tentatively studied with a wide range of dopant (Sr, Pb, Bi, La). It was difficult to draw conclusions since their performances depend strongly on the sample preparation. Moreover, due to the low amount of the dopant, imposed by the low solubility of lead in the calcium site, it was not possible to derive a clear tendency of the substituent’s impact on the oxygen transport properties. However, by pulse isotopic exchange, high surface exchange kinetics were confirmed for the (Ca0.90Sr0.10)3Co4O9+δ composition and it was shown that neither the oxygen adsorption of the surface nor the oxygen incorporation in the solid were the limiting step in the oxygen transfer

Full textThe present work pertains to the development of sol-gel coatings by optimizing the composition and the application parameters for corrosion protection of aluminum alloy AA7075. Different kinds of silanes e.g. tetraethoxysilane (TEOS), phenyltriethoxysilane (PTES) and phenyltrimethoxysilane (PTMS) have been compared: the sol-gel film prepared from PTMS shows highest hydrophobicity manifested by the best barrier property of this compound. The effect of acetic acid as a catalyst on the chemistry of the sol is investigated in order to estimate the best catalyst concentration for better corrosion protection of the coated samples. The corrosion resistance of the coated samples is found to be decreasing at higher concentrations of the catalyst due to the dissolution of the aluminum oxide at the substrate surface in the acid sol. However, lower concentrations of the catalyst lead to low hydrolysis reactions of the silanes and non-dense sol-gel films have been formed. The heat treatment of the coated aluminum samples is required for cross-linking of the film. The heat treatment at 300 ˚C for 2.5 hours exhibits the best corrosion protection. Higher treatment-temperatures lead to degradation of the properties of the film which can be described in terms of destroying the organic part of the film. Moreover, low treatment-temperatures cause low corrosion protection of the coated aluminum samples which is presumably attributed to the low cross-linking of the sol-gel film at temperatures less than 300 ˚C. The coated aluminum samples are characterized by scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX), X-ray photoelectron spectroscopy (XPS) and electrochemical techniques

Full textIn the seventeenth century, dramatic composition, that is, the art of introducing characters on stage in a specific order to relate a story, was revolutionized in the period around 1640 by the establishment of the rule for linking scenes. This new rule decreed that within one act, at least one a character must appear in the two successive scenes. This rule completely changed the aspect of plays in the long term. It imposed an aesthetics of continuity that broke with the discontinuity that had prevailed up until then. In plays from the beginning of the century, action progressed by the juxtaposition of scenes that each presented different characters, thus permitting the playwright to introduce abrupt changes in place, time, and situation. On the contrary, the plays that respect the rule of connection between scenes can no longer count on the intermission alone to renew completely the characters present on stage. Within each act, the action must evolve by successive shifts in meaning, each scene conserving a part of the parameters of the preceding scene. By shedding light on the choices the playwright confronts, the difference between these two aesthetics bares witness to the importance of dramatic composition: writing a play is not simply imagining a plot, but rather giving it a visual form and specifically a theatrical one. This dissertation thesis, then, is interested in both the stakes of the rule for linking scenes itself, and more generally, in the poetics of the positioning of scenes, and in dramatic “editing” with which the playwright engages in order to give body to fiction

Full textThis work consists of a historic-descriptive study, based on theoretical and field research, of the work of Companhia da Arte Andanças, in Fortaleza, Brazil, presenting some methodologies employed throughout processes in class of scenic creation in order to contribute to the discussion and the \"resignification\" of different ways of making and understanding the praxis of the actor/dancer/performer. I propose a new look at the creation process of the play \"O Tempo da Paixão ou O Desejo é um Lago Azul\", which was liberally inspired by the work of the visual artist, José Leonilson (1957-1993), from Ceará, Brazil. In the first part, I describe the trajectory and the activities of the company, along with some of its modes of operation. In the second part, I focus the discussion on the principles and methods of its work. In the third part, I immerse myself in the process of assemblage of the afore mentioned play, sampling aspects of its uniqueness. Finally, I present a brief reflection of the relation between technique, creation, and personality, whose connections are supposed to tense a dramaturgical-affective composition.

Kahn, Olivier. "Temps verbaux, point de vue et composition dans les romans de Claude Simon : approche stylistique et génétique." Thesis, Paris 8, 2017. http://www.theses.fr/2017PA080044/document.
Full textThis thesis highlights the relations between verb tenses and textual viewpoint construction and the composition of Claude Simon’s novels as of Wind (1957).Adopting the tense systems theory and revisiting it in connection with the use of verb tenses in the author’s novels, we show how his writing challenges verb-tense systems and a narrative system historically dated with respect to a writing that breaks free from the frames that motivate them. We shall equally show that in these novels temporality and textual viewpoint construction contribute to the plasticity of the novelistic composition. The verb-tense analysis of our corpus, together with that of punctuation, syntax, enunciation, and narrative viewpoint, is articulated in keeping with the composition of the novels. The stylistic approach of all these aspects is combined with the genetic approach, in many instances allowing to explain more accurately the elaboration process of composition and style. Composition must be kept in mind if we consider the radical breaks with a dated novelistic system that lead us to shift the field of reference of the critical analysis. We might say, paraphrasing Mallarmé, that in Claude Simon’s novels, composition makes up for the absence of the traditional timeline. Just as syntax and punctuation are no longer conceived on the scale of the sentence, in Claude Simon we consider that verb tenses and the notion of viewpoint should also be analyzed on the scale of the novel and its macrostructures. This induces us to dwell particularly on the composition of two novels, The Flanders Road and Le Jardin des Plantes: by alternating present time and past time they allow to fully account for their verb-tense composition. This study, that above all concerns Claude Simon’s renewal of the literary idiom, as a consequence contributes to the renewal of the critical methodology allowing to highlight it. Starting from the stylistic and genetic study of Simon’s novels, it shows how literature incites to revise the linguistic approach to language beyond the sentence, but also how narrative poetics reopen the use of language

Full textIn front of problems of management of harbour dredging sediment, today, it appears necessary to find potential solutions of valosisation allowing to answer effectively these problems. the valorisation in civil engineering, of not immergeables sediments of ports of Dunkirk and Saint Louis, presents an alternative solution to the management of these materials. the works undertaken within the framework of this thesis are focused on the one hand, on the valorisation of Saint Louis sediment in road construction, and the other hand on the valorisation of Dunkirk sediment in concrete as well as artificials agregates. After physicochimical characterisation, mineralogical and mechanical, environmental impact of raw sediment of Saint Louis harbour and the potential use of these materials in road constuction are evaluated. the study of formulation of materials, for use in layer fondation, was based on an experimental method of determination of maximum compactness. The optimal granular mixtures fulfilling the terms of a use in a layer fondation are the evaluated through leaching tests. The concrete party concerns the formulation of the concretes containing Dunkerk sediment. After the characterisation of these materials, three concretes were the object of a durability study vis-a-vis the external sulphate attack associated with a not destructive characterisation in order to study the influence of incorporation of sediment on properties of concretes. The artificial aggregates party presents the feasibility study of aggregates with sediment, the granular plate and the big-bag technique are two making method used

Full textLD converter steel slags are industrial by-products resulting from Linz-Donawitz steelmaking process in oxygen converters. Due to a dimensional instability, attributed to lime and magnesia contained into slag grains, they are not much valuated in road construction. The aim of this PhD thesis, concerning LD steel slags coming from ArcelorMittal Dunkirk steelmaking plant, was : (i) identify the minerai phases responsible for their instability and understand the mechanisms leading to dimensional damages, (ii) isolate into the steelmaking plant the slag outflows that are sufficiently stable for an use in road construction. Carefully chemical and mineralogical characterisations of these slags showed that they contain calcium silicates (essentially dicalcium silicate and punctually tricalcium silicate), calcium ferrites, iron oxides and two forms of lime: sorne nodules and sorne micro-inclusions. It was also established that without the presence of magnesia, lime is the only phase responsible for dimensional damages and that its distribution into slag grains (nodules, micro-inclusions) has a major influence on their stability. Moreover, taking account of certain industrial parameters, it is expected to produce stable slag grains and to incorporate them into wearing course, roadbase, base course or surface dressing. This work finally provides a new way for valuating LD converter steel slags

Full texts Supplier Portal System which was employed in year 2003, as an e-procurement technology for the procurement of direct goods, is taken into consideration. Pointing from the findings of the survey, a usability evaluation methodology is developed based on user and task analysis of the Supplier Portal. Within this methodology, in terms of performance metrics of the Supplier Portal, usability attributes to be measured are determined and a checklist for a heuristic system evaluation is developed. iv While a laboratory testing structure is proposed for the case, a usability satisfaction survey and empirical usability tests are implemented with the actual users of the Company Supplier Portal. Descriptive and inferential formal analyses of the survey and field test results are studied, contributing to the Usability Evaluation of the Portal. Lastly further prospects are pointed, where usability, formal analysis, supply chain management and systems design intercept.

Full textThe Dictio Ennodi diaconi quando de Roma rediit, the Itinerarium Brigantionis castelli and the Itinerarium (Padi) of Magnus Felix Ennodius, as regards the occasion they move from, can be considered as ‘hodoeporic’, even if they reserve much more attention to the description of natural world – usually cruel and hostile – than to the travel story itself. The importance of natural descriptivism is just one of the peculiarities of these poems. They’re very useful to Ennodian studies, for autobiographical information, stylistic and technical features, literary models, Classical and Christian allusions, themes dealt. The present study starts from a general introduction on Ennodius and his corpus, giving attention to matters still not clarified by critics; it also deals with the genesis of the 'collection' of Ennodius’ works and after a description of the main manuscripts used for the edition, we find a presentation of the three compositions, in order to illustrate topoi and main features and to gather the evolution of Ennodius’ style and his literary conceptions. The introduction ends with a section dedicated to the structure of the critical apparatus and to the sigla codicum. The commentary (ad verbum) is preceded by a long introduction on each poem; then we find the critical text and the translation, the first integral into Italian. The study ends with some final considerations about Ennodian hodoeporic. Then we find a list of Ennodian works cited and the bibliographic references

Resumo: O objetivo do trabalho é discutir a questão das técnicas nos processos criativos relacionados a práticas musicais e sonoras ao (1) realizar uma investigação reflexiva/conceitual; (2) ao realizar uma abordagem mecanológica de determinadas técnicas musicais/sonoras; e (3) ao apresentar trabalhos de criação realizados durante o doutorado. Essas três abordagens são apresentadas, respectivamente, nas três partes do trabalho - consideravelmente independentes entre si. A primeira apresenta criticamente diferentes apreensões sobre a técnica. A um fatalismo identificado, apesar de suas particularidades, no pensamento de Heidegger, Benjamin e Adorno é contraposto o pensamento de Gilbert Simondon. Recusando o hilemorfismo (que segrega forma e material), Simondon compreende a técnica como um artefato cultural que preserva em seu dinamismo gestos e pensamentos humanos. Ao ser aproximada dos processos criativos na música, tal perspectiva permite entrever uma relação menos conflituosa entre técnica e criação musical, compreendendo-se então a interação com as técnicas nesses contextos não mais a partir de um viés meramente utilitário ou instrumental, mas, antes, como um processo transdutivo de acoplagem entre expressões, gestos e pensamentos que emanam tanto do homem quanto da sua sedimentação no dinamismo dos mecanismos técnicos. Na segunda parte do trabalho é empreendida, a partir da exposição de determinadas técnicas e de suas utilizações em contextos musicais, uma mecanologia das técnicas musicais e sonoras e de práticas a elas relacionadas. Tal abordagem é realizada a partir do estudo de determinados objetos e mecanismos técnicos e a partir de uma interpretação das implicações dessas invenções em desenvolvimentos técnicos subsequentes assim como de sua apropriação e reinvenção em processos criativos específicos. A terceira parte do trabalho apresenta brevemente as composições realizadas durante o doutorado, cujas partituras foram incluídas aos apêndices do trabalho
Abstract: The thesis objective is to discuss the matter of technology in creative processes related to sound and musical practices by (1) undertaking a conceptual/theoretical inquiry; (2) by undertaking a mecanological approach of certain musical/sound technologies; (3) by presenting creative works produced during the doctorate studies. These three approaches are presented, respectively, in the three parts of the work - which are significantly independent from each other. The first section critically exposes different theoretical understandings of technology. Gilbert Simondon's outlook is counterposed to a sort of fatalism that may be perceived in the theoretical thought of Heidegger, Benjamin and Adorno, despite the very specific features of these philosophers' ideas. By refusing an hylomorphism (that segregates form and material), Simondon conceives technical things as a cultural artifacts which retain in their dynamism human gestures and thoughts. By relating these ideas to music and its creative processes, such a perspective allows us to glimpse a less quarrelsome relation between technology and musical creation, what allows us to understand the integration of technical things in these contexts not by an utilitarian and instrumental approach but rather as a transductive process of coupling between human expressions, gestures and thoughts and their sedimentation in the dynamic mechanisms of technical things. By exposing certain technologies and their use in musical contexts, the second part of the thesis enterprises what is here called a mecanology of musical/sound techniques and related practices. Such exposition comprises the study of certain technical mechanisms and an interpretation of such inventions including their subsequent technical developments as well as their appropriation and reinvention in specific creative processes. The third part of the work presents briefly compositions that were written during the doctorate studies. The scores of these compositions were included in the thesis' appendices
