ABSTRACT Introduction The accuracy of an impression remains critical factor in achieving passive fit of an implant framework. The accuracy of the master cast would depend on the type of impression material, the implant impression technique and accuracy of die material. The different impression techniques advocated in the literature for implant impressions include direct (open tray) and indirect (closed tray) techniques. Direct technique use square impression copings that are picked up in the impressions which were used in this study. Objective To evaluate the accuracy of direct impression made with resin splinted and bis-GMA splinted open-tray impression coping. Thus to compare the accuracy of impressions obtained using different splinting materials. Materials and Methods A wax mandibular reference model was fabricated and four implants were placed in the mandibular anterior region using surveyor and acrylized with clear heat cure acrylic resin using injection molding technique. Spaced primary cast was fabricated with a uniform thickness of space about 2 mm. Ten custom trays were fabricated using the light curable resin sheets. Medium body polyether impression material was used. Pentamix was used to get a uniform mix. These trays were randomly divided among the two groups, with five trays in each group. Impression techniques were divided into two groups namely: Group A - direct impression technique with open tray impression copings splinted with autopolymerizing acrylic resin (GC pattern resin), group B - direct impression technique with open tray impression copings splinted with Protemp TM4 (bis- GMA) syringable temporisation material. Thus, final impressions were made. Total of 10 master casts were fabricated. Evaluation of casts using Dynascope-Vision engineering, Tesa Microhite 2D and coordinate measuring machine were used. Results Statistical comparisons were made using ANOVA test and post-hoc test. Same amount of deviation values obtained with resin splinted and bis-GMA splinted impression copings. The difference in the values might be because of the variation in the rigidity of the materials used. Conclusion Both the splinting material exhibit similar accuracy in impression, so bis-GMA can be used, which is easy to handle, less time consuming, less technique sensitive, rigid and readily available material in clinics, instead of resin splinted material which is technique sensitive, more time consuming and cumbersome.

Movement of impression copings inside the impression material using a direct (open tray) impression technique during clinical and laboratory phases may cause inaccuracy in transferring the 3-dimensional spatial orientation of implants intraorally to the cast. Consequently, the prosthesis may require corrective procedures. This in vitro study evaluated the accuracy of 3 different impression techniques using polyether and vinyl polysiloxane (VPS) impression material to obtain a precise cast for multiple internal connection implants. A reference acrylic resin model with 4 internal connection implants was fabricated. Impressions of the reference model were made using 3 different techniques and 2 different impression materials. The study consisted of 24 specimens divided into 6 groups of 4 each. Impressions were poured with ADA type IV stone (Kalrock, Kalabhai Karson Pvt Ltd, Mumbai, India). All casts were evaluated for the positional accuracy (mm) of the implant replica heads using a profile projector. These measurements were compared to the measurements calculated on the reference resin model, which served as a control. Data were analyzed with 2-way analysis of variance (ANOVA) followed by Bonferroni multiple comparison procedures to evaluate group means. The results revealed significant difference for anterior implant distance between the 2 impression materials (P < .01) and also among the 3 different techniques (P < .05). The lowest mean variation was found with the polyether impression material and the splinted technique. For posterior implants, the results suggested no significant difference between the 2 impression materials (P ≥ .05). Although results were not statistically significant, the polyether impression material showed the lowest mean variation as compared to the VPS impression material. However, there was a significant difference among the 3 different techniques (P < .05). Among the 3 different techniques, the lowest mean variation between 2 posterior implants was found in the splinted technique. Casts obtained from impression techniques using square impression copings splinted together with autopolymerizing acrylic resin prior to the impression procedure were more accurate than casts obtained from impressions with nonmodified implant impression copings and with airborne particle–abraded, adhesive-coated copings. Casts obtained from polyether impression material were more accurate than casts obtained from vinyl polysiloxane impression material.

Introduction. Intraoral scanners allow direct images of oral situation, with fewer steps than conventional impressions. The purpose of this study was to compare the accuracy of digital impressions, traditional impressions, and digitalization of full-arch gypsum models, to evaluate timing of different methods and finally to study perception of patients about conventional and digital impression techniques. Methods. Dental arches of fourteen patients were evaluated by alginate impression, titanium dioxide powder-free intraoral scanning (Trios, 3Shape), and digitalization obtained from gypsum models using the same scanner. Conventional and digital techniques were evaluated through measurements (lower and upper arch anteroposterior length, lower and upper intercanine distance, and lower and upper intermolar distance) with a caliber for analogic models and using a computer software for digital models (Ortho Analyzer, Great Lakes Orthodontics). In addition, chairside and processing times were recorded. Finally, each patient completed a VAS questionnaire to evaluate comfort. Statistical analyses were performed with ANOVA and Tukey tests for accuracy measurements and paired t-test for times and VAS scores. Significance was predetermined at P<0.05. Results. The measurements obtained with intraoral scanning, gypsum models after conventional impression, and digitalized gypsum models were not significantly different. Both chairside and processing times of digital scanning were shorter than the traditional method. VAS reporting patients comfort were significantly higher when evaluating digital impression. Conclusions. Intraoral scanners used for orthodontic applications provide useful data in clinical practice, comparable to conventional impression. This technology is more time efficient than traditional impression and comfortable for patients. Further evolution with more accurate and faster scanners could in future replace traditional impression methods.

Impression techniques should precisely represent the 3-dimensional status of implants to allow for the fabrication of passively fitting prostheses and subsequently the elimination of strain on supporting implant components and surrounding bone. The aim of this study was to compare the accuracy of an abutment level impression method with that of an implant level (direct and indirect) impression method using polyether impression material to obtain precise definitive casts and prostheses. A reference acrylic resin dentoform with 2 internal connection implants (Implantium) was made. A total of 21 medium-consistency polyether impressions of the dentoform, including 7 direct implant level, 7 indirect implant level, and 7 abutment level (after 2 straight abutments were secured), were made. Impressions were poured with American Dental Association (ADA) type IV stone, and the positional accuracy of the implant replica heads and abutment analogs in each dimension of x-, y-, and z-axes, as well as angular displacement (Δθ), was evaluated using a coordinate measuring machine. Noble alloy 3-unit castings were fabricated and seated on the abutments in 3 groups; marginal discrepancies were measured at 4 points between prostheses and abutments. Data were analyzed using Mann-Whitney U test, 1-way analysis of variance (ANOVA), and Kruskal-Wallis tests. In comparisons of different impression techniques, only significant statistical Δθ differences were noted between the abutment level method and other techniques (P < .001). Results of this study reveal that although the implant level impression method could better transfer the angular position of the implants (Δθ), the impression method could not affect Δy, Δx, and Δz coordinates of the implants or marginal discrepancy of the 3-unit fixed partial dentures (FPD).

Irreversible hydrocolloid impressions are easily contaminated with saliva and blood that are potentially capable of cross-infection. Disinfection with addition of Silver (Ag) nanoparticles into the impression material has been explored recently. This research aims to evaluate the in-vitro efficacy of Ag nanoparticle-incorporated irreversible hydrocolloid impression material. Ag nanoparticles (AgZrPO4, National Direct Network Company, Thailand) at concentrations of 0.50%, 1.00% and 1.50% w/w were added to powder of impression material (Kromopan, Lascod, Italy). Impression material samples were prepared on sterile plate in accordance with manufacturer’s instruction. After setting, a 100 microliter of P. aeruginosa ATCC 6538 and C. albicans ATCC 13803 suspension (106 cells/mL) were inoculated on the surface of the impression sample and left for 10 minutes. The amount of the P. aeruginosa and C. albicans on the surface was quantified using imprint technique on the individual culture media respectively. Impression materials incorporated with AgZrPO4 showed antimicrobial property against microbes compared with control (impression material without AgZrPO4). This beneficial effect can be used to reduce cross contamination. However, further investigations are required to study the physical properties of the Ag nanoparticle-incorporated impression material.

Background: with the emergence of technological innovations in the dental industry, one emerging trend has been the intraoral digitizing of patients by using intraoral scanning systems. Compared to taking conventional impressions, the use of intraoral scanners (IOS) is suitable for capturing direct optical impressions, helping to improve diagnostic efficacy, save time, reduce patient discomfort, and simplify clinical procedures. Intraoral scanning systems appear to have a high potential for providing guidance on proper standards of care. However, one main disadvantage is breathing and saliva secretion, which causes deviations, interfering with the applicability and accuracy of the optical impression. The aim of this study was to compare the validity and accuracy of three commercially available intraoral scanners, performing an analysis exploiting a wet model. Methods: an in vitro experimental study of four permanent teeth (two molars and two premolars) on the accuracy of copings obtained by subgingival preparations was performed, using an oral wet environment model. Two hundred and forty digital impressions were produced from three digital scanners using four samples. Descriptive analysis was performed using mean, standard deviation, and median. ANOVA and F-tests were performed to assess the amount of variability between the groups. For statistical analysis a 95% significance level was chosen. Results: all differences between groups were statistically significant. Conclusions: the present data implicate a huge impact of the oral biological fluids on the accuracy of digital impression to corresponding images, implying a failure of accurate impression under wetness conditions.

Intraoral scanners (IOSs) are devices used for capturing direct optical impressions in dentistry. IOS eliminates the errors that are encountered with the conventional impression making procedures. The last decade has seen an increasing number of optical IOS devices, and these are based on different technologies. The objective of this review article is to discuss intraoral scanners with regards to its technology, generation systems, scanning paths, necessity of a powdering medium, accuracy (Trueness and precision), intermaxillary relationship registration, commercially available IOS, clinical recommendations, advantages, disadvantages, indications and contraindications. Digital impressions with IOS is likely going to be a routine procedure in dentistry in the near future.

To compare the three-dimensional accuracy of an open-tray and two snap on impression techniques (with and without connecting the plastic caps of the snap on impression transfers) in a full arch 6-implant model, a reference acrylic resin model of the maxilla with six implants was fabricated. Prominent geometrical triangles, in the palate area, served as reference points for a digital overlap between scans. Three impression transfer techniques were evaluated and compared: open-tray direct impression (DI), snap on impression (SpO), and connected snap on impression (SpOC). Polyether impression material was used to make 30 impressions (n = 10), and the master model and all casts were digitally scanned with a laboratory optical scanner. The obtained 3D data were converted and recorded as STL files, which were imported to a 3D inspection software program. Angular deviations (buccal, occlusal and interproximal planes) between the study casts and the reference model were measured. Data were analyzed using one-way analysis of variance (ANOVA) and Tukey post hoc test, with 0.05 used as the level of significance. The 3D angular deviations from the master model revealed no significant differences between the DI and SpO impression groups, but there were significant differences in the SpOC impression group, particularly in the buccal and occlusal planes. In all groups, the 3D angular deviation between the most distal scan abutments on each side of the model was significantly different from all other areas when compared to the master model. Within the limits of this study, it is possible to conclude that the indirect closed tray snap on impression technique with unconnected plastic caps exhibited the same three-dimensional accuracies as the direct open tray technique. The indirect closed tray snap on impression technique with connected plastic caps was less accurate than either the indirect closed tray snap on impression technique with unconnected plastic caps or the direct open tray technique. In the case of full arch implant supported prostheses, inaccuracies may be expected in the most distal implants for all the three impression techniques evaluated in this study. Further in vitro and in vivo research is required.

BACKGROUND We intend to evaluate the accuracy of in vivo conventional and digital methods in generating complete-arch dental models for measuring tooth dimension. METHODS Search was conducted through an electronic database in Medline, Cochrane Library, ResearchGate, PubMed and Google Scholar using query terms such as intraoral scanning; digital impression; accuracy in vivo full arch digital impression; analog impression; accuracy conventional impression; in vivo intraoral scanning; alginate impression; accuracy of plaster models; digital models; and complete arch accuracy. The outcomes were the accuracy of teeth dimension measurements in plaster models in comparison to digitized and digital models in vivo. RESULTS Nine studies matched the inclusion criteria. Two papers compared teeth measurements through plaster models and direct digital models, four papers compared plaster models and digitized models, one paper compared plaster models, digitized and direct digital models, one paper compared four different methods of direct intraoral, plaster models, direct digital and digitized models and one study reported teeth measurements from directly measured intraoral, plaster models, and direct digital models. Neither digital nor plaster models could be considered to replicate exactly the dentition, however it was agreed by the authors that intraoral scanning could represent the intraoral situation more accurately on digital models due to the lesser procedural steps, hence fewer source of error. CONCLUSIONS According to the results of the present review, although there were slight differences in readings of the measurements made on all the methods, the differences were neither statistically nor clinically significant and it is acceptable in clinical application. This review was registered in PROSPERO at CRD42020208662.

La chaire MINT (innovating for molded & printed electronics) est une Chaire d’Excellence scientifique soutenue par la Fondation Partenariale Grenoble INP et ayant pour mécène Schneider Electric. Au travers de la Chaire MINT, Schneider s’engage avec deux laboratoires de recherche, le LGP2 et l’IMEP-LaHC dans le but de développer des fonctionnalités électroniques sur des thermoplastiques de forme 3D. La Chaire MINT a donné lieu à la thèse : « intégration de fonctions électroniques imprimées sur des thermoplastiques 2D et 3D pour des applications radiofréquences ».Les objectifs de cette thèse sont les suivants : mettre en œuvre, caractériser et optimiser le procédé d’impression jetting sur thermoplastique 2D et 3D. De plus, afin de pouvoir définir les limites et les atouts de cette technologie pour des applications radiofréquences, les performances de ce procédé en radiofréquence doivent être évaluées. Des dispositifs ont également été mis en œuvre afin d’illustrer les possibilités du procédé.Pour cela la thèse est présentée en trois chapitres : dans un premier temps une étude bibliographique est réalisée sur les procédés plastroniques et leurs applications actuelles de dresser un état de l’art du domaine plastronique. Les technologies plastroniques sont détaillées et une proposition de classification de celles-ci parmi les technologies de fabrication additives 3D maitrisées est proposée. Des dispositifs réalisés en technologie plastroniques sont présentés pour chacun des domaines abordés. Dans un deuxième temps le développement du procédé de jetting et sa caractérisation géométrique et électrique est présenté. Les paramètres d’impression sont étudiés et optimisés pour une impression robuste. Des stratégies d’optimisation de l’impression sont mises en place.Finalement, à travers une caractérisation de ligne de transmission coplanaire en 2D et en 3D, une évaluation des performances radiofréquence des impressions avec le procédé jetting est réalisée. Des lignes coplanaires en 2D sont simulées et imprimées. Une optimisation de l’impression est réalisée en imprimant des plans de masse maillés. Des lignes coplanaires sont également imprimées sur des substrats 3D comportant des angles à 90° et à 130°, puis mesurées. Des applications radiofréquences sont ensuite détaillées sur des substrats 2D et 3D tels qu’une antenne LoRa, un tag RFID et un radôme pour antenne 5GThe MINT chair (innovating for molded & printed electronics) is an Excellency scientific chair supported by the Fondation Partenariale Grenoble INP and sponsored by Schneider Electric. Through MINT chair, Schneider teams up with two research laboratories, the LGP2 and the IMEP-LaHC, to develop electronic features on 3D shaped thermoplastics. The MINT chair gave rise to the thesis: « Printed integration of electronic capabilities on 2D and 3D thermoplastic for radiofrequency implementations »This thesis goals are the implementation, characterization and optimization of the jetting impression process on 2D and 3D thermoplastic. Moreover, the performances of this process must be assessed in order to define its strengths and limits in a radiofrequency usage. Finally, the process capabilities were showcased by printing prototypesTo this end, this dissertation is split into three successive chapters. Firstly, the state of the art of the plastronic field, carried out through literature review on plastronic processes and their current implementations, is presented. Plastronic technologies are examined and a classification amongst well-known 3D additive manufacturing technologies is proposed. Prototypes made with plastronic technologies are displayed for each concerned field. Secondly, the electrical and geometric characterization as well as the implementation of the jetting process is presented. Printing parameters are studied and optimized to determine a resilient printing process and printing optimization strategies are set up. Finally, jetting process printouts radiofrequency capabilities are assessed through characterization of 2D and 3D coplanar transmission lines. 2D coplanar transmission lines are simulated and printed. The printing process is optimized by printing meshed ground planes. Coplanar lines are printed on 3D substrates having 90- and 130-degrees angles, then measured. Some radiofrequency implementations are examined: a LoRa antenna, a RFID tag and a 5G antenna radome

Les études pharmacocinétiques réalisées grâce à la tomographie d’émission par positrons chez le petit animal requièrent la mesure de la concentration du radiotraceur dans le sang, la fonction d’entrée, pendant la séquence d’imagerie. Un détecteur de positrons placé sur une canule prélevant le sang de l’animal a été démontré comme un moyen avantageux de mesurer la fonction d’entrée chez les rongeurs, mais souffre d’une efficacité de détection limitée. Une nouvelle génération de compteur a été développée afin de surmonter ce problème. Des cartouches microfluidiques, fabriquées par impression 3D dans un matériau biocompatible, remplacent les cathéters traditionnellement utilisés et permettent de diminuer la perte d’énergie des positrons dans les parois. De plus, un circuit de différentiation, implanté via une topologie d’amplificateur d’instrumentation, permet la suppression du bruit induit par le fluide conducteur présent entre une paire de détecteurs opposés. Le système est ainsi beaucoup moins vulnérable que ses prédécesseurs aux interférences électromagnétiques présentes dans l’environnement expérimental. L’efficacité de détection du système utilisant un seul détecteur avec un cathéter PE-50 a été caractérisée comme étant de 17,3 % pour le [indice supérieur 18]F, 25,2 % pour le [indice supérieur 11]C et 1,3 % pour le [indice supérieur 99m]Tc, soit des augmentations de facteurs 4, 2 et 6,5 respectivement, lorsque comparé au système en cathéter antérieur. Une caractérisation subséquente à deux détecteurs a vu les efficacités de détection du [indice supérieur 18]F et du [indice supérieur 11]C augmenter d’un facteur 1,9, soit presque doubler. Une diffusion du liquide hors du microcanal a été observée lors de l’utilisation des cartouches microfluidiques, ce qui modifie le volume de détection au cours de l’acquisition et rend impossible la détermination de l’efficacité de détection avec un microcanal. Bien que ceci démontre que la technologie d’impression 3D choisie est inadaptée à l’utilisation dans une application microfluidique, de récents développements dans le domaine font de la stéréolithographie un remplacement fort prometteur pour la fabrication de microcanaux. L’utilisation de cathéters de polyimide avec parois très minces, comme alternative à la microfluidique, a entraîné des augmentations d’efficacité de détection de 3,2 % et 5,7 % pour les isotopes [indice supérieur 18]F et [indice supérieur 11]C respectivement. L’effet du cathéter de polyimide est encore plus marquant avec le [indice supérieur 99m]Tc, faisant passer l’efficacité de détection de 1,0 % à 1,8 %. Ce fort gain s’explique par la détection d’électrons de conversion de faible énergie, indétectables avec un cathéter traditionnel. De plus, l’utilisation d’un unique cathéter élimine la complexité inhérente au raccord entre un cathéter et une composante microfluidique. L’appareil développé permettra une mesure plus précise de la fonction d’entrée et, utilisé de pair avec des techniques d’imagerie moléculaire, facilitera les études pharmacocinétiques visant le développement de nouveaux traitements et radiotraceurs.

La structuration sub-micrométrique de grandes surfaces avec une très bonne résolution spatiale pourrait ouvrir de nouvelles frontières dans de nombreux domaines, tels que le stockage de données optiques 3D, la biomédecine ou les micro-dispositifs mécaniques et optiques. Parmi les différentes techniques de fabrication additive, la polymérisation biphotonique a suscité un grand intérêt en raison de sa résolution spatiale, sous la limite de diffraction de la longueur d'onde considérée. Néanmoins, cette technique souffre d'une vitesse d'écriture limitée et d'un coût d'exploitation élevé qui ralentissent son entrée sur le marché. Le but de ce projet de thèse est d'accroitre la vitesse de fabrication par polymérisation biphotonique en fabriquant plusieurs structures en parallèle grâce à la combinaison d’une source laser appropriée et d’éléments optiques diffractifs (EOD) avec une résine à faible seuil de polymérisation. Dans ce cadre, deux nouveaux photoamorceurs biphotoniques ont été synthétisés et caractérisés finement au moyen de multiples techniques (spectroscopies linéaire et non-linéaire, spectroscopie de résonance paramagnétique électronique, voltampérométrie cyclique, microfabrication, spectroscopie Raman). Leur utilisation au sein d’un mélange de monomères acrylates choisis a permis de mettre en évidence le fort potentiel de ces nouveaux amorceurs, comparé à ceux de la littérature. Les seuils de polymérisation ainsi que les dimensions des structures fabriquées ont été déterminés et corrélés à un modèle mathématique. Une méthode de quantification des rendements quantiques de photoamorçage combinant l'actinométrie chimique et la spectroscopie RMN du fluor a été proposée. L’impression simultanée en parallèle de 121 structures a été réalisée, nous conduisant à soulever les problèmes liés aux effets de proximité dans de telles conditions de fabrication ainsi qu’à proposer des voies d’améliorationThe fast patterning of sub-micrometric structures with high three-dimensional (3D) spatial resolution over a large area could open new frontiers in many fields such as 3D optical data storage, biomedicine or mechanical and optical micro-devices. Among the various additive manufacturing techniques, two-photon polymerization (TPP) has attracted a high level of interest due to the spatial resolution it offers, below the diffraction limit of the wavelength used. Nevertheless, this technique suffers from a limited writing speed and a high operating cost which slow down its entry on the market.The goal of this thesis project is to increase the building speed of TPP by fabricating several structures in parallel thanks to the combination of an appropriate laser source and diffractive optical elements (DOE) with a low polymerization threshold resin. In this framework, two new two-photon photoinitiators were synthesized and finely characterized using multiple techniques (linear and nonlinear spectroscopies, electron paramagnetic resonance spectroscopy, cyclic voltammetry, TPP microfabrication, Raman spectroscopy), highlighting their strong potential compared to benchmarks. The polymerization thresholds and the dimensions of the manufactured structures were determined and correlated to a mathematical model. A method for quantifying photoinduced radical generation quantum efficiencies by combining chemical actinometry and 19F NMR spectroscopy has been proposed. Simultaneous parallel printing of 121 structures was performed, revealing issues related to the proximity effects under such fabrication conditions, which we partially solved

Magister Chirurgiae Dentium - MChDMeasurements and a variety of analyses of dental casts are essential for precise diagnosis of an orthodontic case. Study models have long been an essential part of orthodontic diagnosis and treatment planning. Currently virtual computerized models are available to clinicians, supplemented by dedicated software for performing needed measurements (Zilberman et al, 2003). Digital impression methods are now available and intraoral digital scanning techniques make it possible to generate study models directly from the scanning of the dentition. The aim of this study was to compare measurements taken after scanning the dental impressions to the measurements obtained from using direct intraoral scanning of the dentition. Alginate impressions of the maxillary and mandibular dentitions were taken on 20 patients and these impressions were scanned using a 3 Shape R 700 TM scanner. Direct intraoral scans of both dentitions were then performed for the same patient. Ortho analyzer TM software was used to measure the mesiodistal widths of individual teeth, and the intercanine and intermolar on digital models of the scanned impressions and digital models obtained from direct intraoral scans of the maxillary and the mandibular dentitions. The results indicated that there were no statistically significant differences between mesiodistal widths, and intercanine and intermolar distances between the two techniques (p > 0.05). Because of the high level of accuracy of the virtual measurements compared to those of the scanned impressions, it can be concluded that direct intraoral scanning of the dentition can be used with confidence in the clinical situation to measure tooth sizes and inter-arch distances for orthodontic purposes. Orthodontists commonly use models for various areas in the practice, clinical research and medico-legal documentation (Marcel, 2001)

Parallèlement à l’impression jet d’encre et au bioplotting, l’impression d'éléments biologiques assistée par laser (Laser Assisted Bioprinting : LAB) qui utilise le transfert vers l’avant induit par laser (Laser Induced Forward Transfer : LIFT) a émergé comme une méthode alternative dans l’assemblage et la micro–structuration de biomatériaux et de cellules. Le LAB est une technique d’écriture directe qui offre la possibilité d’imprimer des motifs avec une haute résolution spatiale à partir d'une large gamme de matériaux solides ou liquides, tels que des diélectriques, des biomolécules et des cellules vivantes en solution.Dans nos travaux de recherche, nous avons considéré une approche expérimentale et numérique pour étudier les mécanismes physiques mis en jeu lors de la microimpression d’éléments biologiques assistée par laser. Dans un premier temps nous avons défini les paramètres rhéologiques des bioencres et les conditions de transfert (composition, épaisseur et viscosité de la bioencre et énergie laser). Puis nous avons mené une analyse statistique du volume des gouttelettes déposées pour quatre viscosités de bioencre, cinq épaisseurs de bioencre et cinq énergies laser. Ensuite nous avons conçu et mis en place un système d’imagerie résolue en temps pour étudier les effets de la viscosité sur la dynamique de l’éjection. Nous avons ainsi différencié trois régimes d'éjection en fonction de l'énergie laser déposée dans la couche absorbante, de la viscosité et de l'épaisseur de la bioencre. Parallèlement, un modèle numérique a été mis en place pour comprendre et prédire la dynamique de l’éjection en fonction de paramètres multiples : choix et épaisseur de la couche absorbante, épaisseur de la couche de bioencre, énergie laser déposée. Enfin, au regard de ces études, nous proposons un mécanisme d'éjection des microgouttelettes intervenant au cours du procédé de microimpression assistée par laserOver this decade, cell printing strategy has emerged as one of the promising approaches to organize cells in two and three dimensional engineered tissues. In parallel with ink-jet printing and bioplotting, Laser Assisted Bioprinting (LAB) using Laser-Induced Forward Transfer (LIFT) has emerged as an alternative method in the assembly and micropatterning of biomaterials and cells. LAB is a laser direct-write technique that offers the possibility of printing micropatterns with high spatial resolution from a wide range of solid or liquid materials, such as dielectrics, biomolecules and living cells in solution. In our research works, we considered an experimental and numerical approach to study the physical mechanisms involved in the biological elements microprinting laser assisted.First we defined the rheological parameters of bioinks and the transfer conditions (composition, thickness and viscosity of the bioink and laser energy). Then we led a statistical analysis of the volume of the transfer droplets for four viscosities of bioink, five thicknesses of bioink and five laser energies. Then we designed and implemented a system for time resolved imaging to study the effects of viscosity on the dynamics of the ejection. Thus we have differentiated three ejection regimes in function of the laser energy released in the absorbing layer, the visocsity and the thickness of the bioink. In parallel, a numerical model was developed to understand and predict the dynamics of the ejection parameters according to multiple choice and thickness of the absorbing layer, thickness of the layer bioencre, energy deposited. Finally, with regard to these studies, we propose a mechanism for ejecting droplets involved in the process of laser-assisted microprinting

Orientador: Rafael ZadorosnyResumo: Neste trabalho é apresentada a produção de condutores revestidos de material supercondutor (superconducting coated conductors – SCC), ou seja, um filme supercondutor cerâmico, obtido por impressão direta da solução precursora sobre um substrato. Este processo foi estudado com o intuito de aplicar uma técnica de fabricação simples e de baixo custo visando a obtenção de filmes de boa qualidade a um custo reduzido. As soluções precursoras de CeO2, BSCCO e YBCO foram obtidas pelo método Pechini, considerada uma rota de produção de baixo custo. A fim de comparar a impressão direta com outra técnica, foram produzidos os mesmos filmes por spin coating. Para se obter os SCC, foi adicionada Ag às soluções dos materiais cerâmicos verificando sua incorporação na estrutura do filme e não apenas como um material de revestimento (como ocorre com as fitas supercondutoras de segunda geração). As caracterizações morfológicas e estruturais foram realizadas para identificar e analisar o processo de impressão direta do SCC. Já o comportamento supercondutor do material foi verificado através de medidas de R x T.
Abstract: This work presents the production of superconducting coated conductors (SCC), that is, a superconducting ceramic film obtained by direct printing of the precursor solution on a substrate. This process was studied with the intention of applying a simple and low cost technique focusing in the obtaining of good quality films at a reduced cost. The precursor solutions of CeO2, BSCCO and YBCO were obtained by the Pechini method, also considered a low cost production route. In order to compare direct printing with another technique, the same films were produced by spin coating. In order to obtain the SCC's, Ag was added to the solutions of the ceramic materials to incorporate in the film structure and not just as a coating material (as with second-generation superconducting tapes). Morphological and structural characterizations were performed to identify and analyze the SCC obtained by direct printing process. The superconductive behavior of the material was verified by measurements of R x T.

[EN] Numerous scientific studies have shown the importance and benefits of possessing a positive reputation at both the personal as well as organizational level. Specifically, the impression management theory is an important pillar in building personal reputation to everyday organizational life. Research in this area has demonstrated their interest in particular aspects such as recruitment processes, person-job fit, person-organization fit, job performance appraisal and career success.
Despite the importance of and interest in impression management theory (IM) and the need of organizations to develop a favorable reputation, to date there is no evidence about the influence IM techniques may have on building personal reputation. Nor is there existing empirical evidence of the potential impact that personal reputation may have on the reputation of the organization as a whole. Therefore, examining the relationship between IM, personal reputation and corporate reputation could shed some light on the processes of building reputation in organizations, and particularly its development in the case of communication managers. To this end, this thesis has the objective of studying IM and its dimensions, presenting it as an antecedent of personal reputation (PR) and presenting the relationship between PR and corporate reputation (CR).
To achieve this objective, the research is divided into five chapters. To begin, it is summarized an overview of IM theory. After this state of the art, an integrated definition of the construct is presented. Then, in the second chapter, we examine what the current literature has explained to date about PR in order to relate it to the IM theory. Next, in the third chapter, we analyze the different theoretical perspectives under which the concept of CR has been studied. After studying IM and proposing its relationship with PR and CR the fourth chapter shows a relational model of reputation from the theory of IM that is able to put in dialogue the three constructs (IM, PR and CR). To conclude, the fifth chapter presents a qualitative empirical study based on the grounded theory. The objective is to answer the propositions that emerged from the relational model presented, particularly in the case of Spanish communication managers (DirCom). Finally, the thesis concludes with some reflections on the findings of this research, noting the limitations of the study and proposing avenues for future research.[ES] Numerosas investigaciones científicas han puesto de manifiesto la importancia y los beneficios que reporta a nivel personal y organizacional contar con una buena reputación. En particular, la teoría de la impression management o gestión de las impresiones, constituye un pilar importante en la construcción de reputación personal en el día a día de las organizaciones. Las investigaciones en este ámbito han confirmado su interés de modo particular en los procesos de selección, en la determinación del ajuste del candidato al puesto y/o a la compañía, la evaluación del desempeño laboral y en el desarrollo de carreras profesionales. A pesar de la importancia e interés de la teoría de la impression management (en adelante IM) y de la necesidad de contar con una buena reputación en las organizaciones, no existe hasta la fecha evidencia acerca de la influencia que las técnicas de IM pueden tener en la construcción de reputación personal. Como tampoco existe evidencia empírica de la posible repercusión que pueda tener la reputación personal en la reputación de la organización en su conjunto. Por este motivo, examinar esta relación entre IM, reputación personal y reputación corporativa podría arrojar luz acerca de los procesos de construcción de reputación en las organizaciones, y de modo especial su desarrollo en el caso de los directores de comunicación. Es por esto que en esta tesis se propone como objetivo abordar el estudio de la IM y sus dimensiones, presentándola como antecedente de la reputación personal (en adelante RP), y poniéndola en relación con la reputación corporativa (en adelante RC). Para lograr este objetivo, la investigación se estructura en cinco capítulos. En el primero se lleva a cabo un estado del arte sobre la teoría de la IM, y se ofrece una definición integradora del constructo. En el segundo, se hace una descripción de lo que la literatura ha dicho hasta el momento sobre RP, para ponerlo en relación con la teoría de la IM. En el tercer capítulo, se analizan las distintas perspectivas bajo las que se ha estudiado el concepto de RC. Tras el estudio de la IM, y plantear su relación con la RP y la RC, en el cuarto capítulo, se propone un modelo relacional de reputación desde la teoría de la IM capaz de poner en diálogo los tres constructos (IM, RP y RC). Para terminar, en el capítulo quinto, se presenta un estudio empírico de carácter cualitativo basado en la teoría fundamentada, en el que se responde a las cuestiones de investigación que se desprenden del modelo relacional propuesto en el caso particular de los directores de comunicación españoles (en adelante DirCom). Finalmente, se concluye la tesis con algunas reflexiones acerca de los hallazgos obtenidos, con el reconocimiento de las limitaciones del trabajo y con la propuesta de futuras líneas de investigación.
[CAT] Nombroses investigacions científiques han posat de manifest l'importància i els beneficis que reporta a nivell personal i organitzacional comptar amb una bona reputació. En particular, la teoria de l'impression management o gestió de les impressions, constitueix un pilar important a la construcció de reputació personal en el dia a dia de les organitzacions. Les investigacions en aquest àmbit han confirmat el seu interès de manera particular en els processos de selecció, en la determinació de l'ajust del candidat al lloc de treball i/o a la empresa, l'avaluació de l'acompliment laboral i en el desenvolupament de carreres professionals. Tot i la importància i interès de la teoria de l'impression management (d'ara endavant IM) i de la necessitat de comptar amb una bona reputació en les organitzacions, no existeix fins este moment evidència sobre l'influència que les tècniques d'IM poden tenir en la construcció de reputació personal, com tampoc hi ha evidència empírica de la possible repercussió que puga tindre la reputació personal en la reputació de l'organització en el seu conjunt. Per aquest motiu, examinar aquesta relació entre IM, reputació personal i reputació corporativa podria donar llum sobre els processos de construcció de reputació en les organitzacions, i de manera especial, el seu desenvolupament en el cas dels directors de comunicació. És per això que en aquesta tesi es proposa com a objectiu abordar l'estudi de l'IM i les seves dimensions, presentant-la com antecedent de la reputació personal (d'ara endavant RP), i posant-la en relació amb la reputació corporativa (en endavant, RC). Per aconseguir este objectiu, la recerca s'estructura en cinc capítols. En el primer es porta a terme un estat de l'art sobre la teoria de l'IM, i s'ofereix una definició integradora del constructe. En el segon, es fa una descripció d'alló que la literatura ha dit fins al moment sobre RP, per posar-lo en relació amb la teoria de l'IM. En el tercer capítol, s'analitzen les diferents perspectives sota les quals s'ha estudiat el concepte de RC. Després de l'estudi de la IM, i de plantejar la seva relació amb la RP i la RC, en el quart capítol, es proposa un model relacional de reputació des de la teoria de la IM capaç de posar en diàleg els tres constructes (IM, RP i RC). Per acabar, en el quint capítol, es presenta un estudi empíric de caràcter qualitatiu basat en la teoria fonamentada, en el qual es respon a les qüestions de recerca que es desprenen del model relacional proposat en el cas particular dels directors de comunicació espanyols (en endavant DirCom). Finalment, es conclou la tesi amb algunes reflexions sobre les troballes obtingudes, amb el reconeixement de les limitacions del treball i amb la proposta de futures línies d'investigació.

This manuscript describes development of batch injection analysis (BIA) cells using a 3D printer as well show the fabrication of pencil draw electrode on paper platform. Bia cells were employed on wall-jet configuration coupled with amperometric system. Bia systems were used to detect a product reaction obtained by paper-microreactor and determine ethanol in whiskey samples. Fabrication process using 3D printer was simple, fast (lower than four hours) and cost effectiveness (ca. $ 3.43 and 1.07 to the 1st and 2nd generation of Bia system, respectively). The 1st generation of Bia cell was production to be couple with commercial screen printed electrodes (SPEs) by DropSens (DropSens, DPR 710 model) and 2nd generation have support to put home-made electrodes. Both Bia cells, present a specific compartment to be coupled the micropipette. Paperbased microreactors (MOPs) were used with the 1st generation of Bia cell and the system was employed to measure glucose through the generation of hydrogen peroxide by the reaction of glucose with glucose oxidase and amperometric detection of H2O2 generated in the reaction at a potential of -0.25 V vs. Ag. In the same way of Bia cell, MOPs fabrication process is simpler, faster and cheaper (ca. $ 0.02 cent each). In general, the system shows a good linear response for concentration range between 1 to 10 mmo L-1. The limit of detection (LD) and quantification (LQ) found were 0.11 mmol L-1 and 0.38 mmol L-1, respectively. Besides, the measure of glucose using five different MOPs presented a good repeatability (RSD between 1.5 to 2.8%) and reproducibility (RSD = 0.66%). The 2nd generation of Bia cell was coupled with copper working electrode modified thermally and chemically. This cell was employed to determine the presence of ethanol in whisky sample using 1 mol L-1 NaOH as supporting electrolyte and potential of 0.45 V vs Ag / AgCl. The modified-electrode shows optimum stability to measure seventy minute of consecutive injection with RSD lower than 4.7%. A good linear response was obtained when concentration of ethanol ranged from 2.5 to 25% (v/v). The LD achieved was ca. 0.07% (v/v). Besides the Bia cells experiments, this work describes the fabrication process of alternative electrodes by hand drawing pencil on paper platform. Initially, the geometry of sensing electrodes was drawn using a graphic software and printed on paper surface. During printing process, toner lines were deposited on paper to delimit the electrode area. Then, the desire layout was draw using a pencil and laminated using benchtop laminator. This last step is necessary to make the electrical insulation. Fabrication process of alternative electrodes was simple, fast (~ 20 minutes) and cost effectiveness (ca. $ 0,023). Characterization of paper electrodes was made by cyclic voltammetry with potassium ferrocyanide (5 mmol L-1) in KCl solution (0.5 mol L-1). Besides, showed good peak separation (ΔEp) ca. 238 mV and excellent reproducibility. The RSD was lower than 2.25% to five different electrodes.
Esta dissertação apresenta o desenvolvimento de células para análise por injeção em batelada (BIA, do inglês “batch injection analysis”) mediante uso de uma impressora 3D assim como a fabricação de eletrodos utilizando uma técnica de escrita direta em papel. As células BIA foram utilizadas com detecção eletroquímica, visando a análise de um produto de reação realizada em microrreatores de papel e, também, de etanol em amostras de uísque. As células BIA, fabricadas no laboratório por meio de uma impressora 3D, apresentaram baixo custo (cerca de R$ 12,00 e R$ 3,75 para 1° e 2° geração respectivamente), fabricação rápida (cerca de 4 horas e 1 hora e 40 minutos para 1° e 2° geração respectivamente) e robustez. Ambas as células BIA foram utilizadas com detecção amperométrica (DA) e apresentam configuração wall-jet. A 1° geração BIA possui suporte para eletrodos serigrafados (SPEs) comerciais da DropSens e pipeta eletrônica e a 2° geração BIA possui suporte para eletrodos convencionais construídos no laboratório e pipeta eletrônica. Os microrreatores à base de papel (MOPs) foram vinculados à 1° geração da célula BIA, este sistema foi utilizado para quantificação de glicose a partir da geração de peróxido de hidrogênio mediante a reação da glicose com glicose oxidase, e detecção do H2O2 gerado com SPEs de carbono modificado com azul da prússia (DropSens, modelo DPR 710) em um potencial de -0,25 V versus Ag. A confecção dos MOPs é simples, rápida (2 horas e 30 minutos) e de baixo custo (cerca de R$ 0,06 a unidade). Para a fabricação dos microrreatores a base de papel, primeiramente foi realizada a modificação química da superfície do papel. Para, em seguida, efetuar a imobilização covalente da enzima. Os ensaios realizados utilizando os MOPs vinculados a 1° geração da célula BIA com detecção amperométrica (BIADA) apresentaram linearidade para faixa de concentração entre 1 e 10 mmol L-1 (R² = 0,990), alta repetitividade (DPR entre 1,5% e 2,8%) e elevada reprodutibilidade (DPR = 0,66%) para 5 microrreatores. Os limites de detecção e quantificação obtidos foram de 0,11 mmo L-1 e 0,38 mmol L-1 respectivamente. A 2° geração da célula BIA foi acoplada com eletrodo de trabalho (ET) de cobre modificado por tratamento químico / térmico e utilizada para verificação de adulteração em uísques através da quantificação de etanol utilizando NaOH 1 mol L-1 como eletrólito suporte e potencial de 0,45 V versus Ag/AgCl. Os ensaios utilizando a 2° geração da célula BIA-DA apresentaram linearidade para faixa de concentração entre 2,5 e 25 % v/v de etanol (R² = 0,998) e elevada estabilidade (DPR = 4,7%) para aproximadamente 70 minutos de injeções consecutivas. O limite de detecção obtido para o etanol foi de 0,07% (v/v). Os eletrodos em plataforma de papel foram produzidos através da pintura direta com lápis. Para a fabricação destes dispositivos, primeiramente o layout dos eletrodos são impressos no papel para definir a área do desenho dos eletrodos. Em seguida os eletrodos são pintados com lápis, depois os dispositivos são plastificados com polaseal com o objetivo de isolar os contatos e delimitar a área dos eletrodos. A confecção destes eletrodos é rápida (~ 20 minutos) e de baixo custo (R$ 0,082 a unidade). Os eletrodos foram caracterizados utilizando voltametria cíclica com ferrocianeto de potássio 5 mmol L-1 solubilizado em KCl 0,5 mol L-1. Estes dispositivos apresentaram elevada reprodutibilidade (DPR = 2,25%) para 5 eletrodos distintos.

Previous issue date: 2016-02-23This paper aims to map how 3D printing is already affecting and will affect intellectual property. In Chapter 1, we trace the historical development of intellectual property as well as the philosophical justifications for this related to the development of technologies that work with content (music and movies) such as the internet. Therefore, we make analogies with this case in order to capture insights that can guide the analysis regarding the relation intellectual property and 3D printer . Chapter 2 lends itself to analyze the 3D printer and its development in the market; there are also reflections on the Maker Movement, Open Source Hardware licenses and the environmental effects of this technology. Chapter 3 analyzes cases that have already occurred involving 3D printers and intellectual property, analyzing how this technology further enhances the problem of the performance of intellectual property in the XXI century.
O presente trabalho objetiva mapear de que forma a impressão 3D já afeta e afetará a propriedade intelectual. No Capítulo 1, traça-se o desenvolvimento histórico da propriedade intelectual, bem como as justificativas filosóficas para esta em face do desenvolvimento de tecnologias que trabalham com conteúdos (músicas e filmes) como a interent. São feitas assim analogias com este caso de forma a capturar insights que possam nortear análises a respeito da relação propriedade intelectual e impressora 3D . O Capítulo 2 se presta a analisar a impressora 3D e o seu desenvolvimento no mercado; há também reflexões a respeito do Movimento Maker, licenças Open Source Hardware e os efeitos ambientais desta tecnologia. O Capítulo 3 analisa casos que já ocorreram envolvendo a impressora 3D e propriedade intelectual, analisando-se de que forma esta tecnologia problematiza ainda mais o desempenho da propriedade intelectual no século XXI.

Previous issue date: 2013This dissertation based itself on the autonomy and the consent of the offended in the brazilian juridical scope, throughout the Dignity of the Human Being bias. Therefore, it was done a path of definitions and concepts so, then, these premises could be applied to a concrete case, here, namely, the limit of the autonomy and the consent of the transfusional refuse based on religious convictions. In that way, it was passed on through the concepts of the human being dignity, with a more deep analysis on some aspects of juridical dimension. In this diapason, therefore, it was analysed the possibility of that being capable of assuming faces of principle/rule, from boundaries of the boundaries and, also, the essential core of the fundamental rights. Finally, in this context, it was verified if the dignity of a human being is an exception on the juridical order, aiming to be an absolute principle, proposition that, by the theoretical referential adopted, which it was immediately denied, since that according to Robert Alexy’s theory of principles, that absolute principle doesn’t exist, obviously, absolut principles. Still, in this same line, it was analysed the other institution related to the theme: the autonomy and its relation to the human dignity. Still, in this paper, it were analysed the rector principles to the criminal law, which implies, implicitly or explicitly, the human dignity. Then, in this same path, it was analysed the context of autonomy, previously mentioned, but, now, throughout the criminal law vision, rounded by the juridical paternalism phenomenon and, in that way, in some corners, its (im)possibility, given the reducement of the liberty/autonomy scope of the individual. After that, in this same context, it was analysed the consent of the offended in the criminal perception, as well as its reflexions and implications – with some detach to the availability and the unavailability of the juridical area, as its function in the criminal perception, in other words, the agreement and the consent. After this construction theoretical-perception, it was started the analysis of the case, passing through some institutions related to the theme, specially the objetction to the awareness and the religious freedom in the juridical scope, in order to, finally, answer to one of the central themes of this dissertation: after all, what is the limit of consent and autonomy in the brazilian juridical scope?
Esta dissertação pautou-se pela investigação da autonomia e do consentimento do ofendido no âmbito jurídico brasileiro pelo viés da Dignidade da Pessoa Humana. Para tal, trilhou-se um caminho de definições e conceitos para, então, aplicar essas premissas a um caso concreto, aqui, nomeadamente o limite da autonomia e do consentimento da recusa transfusional por convicção religiosa. Assim, percorreu-se pelas feições da dignidade da pessoa humana analisando mais detidamente alguns aspectos da sua dimensão jurídica. Neste diapasão, portanto, analisou-se a possibilidade que ela possui de assumir feições de princípio/regra, de limite dos limites e, também, de núcleo essencial dos direitos fundamentais. Por fim, neste contexto, se verificou se a dignidade da pessoa humana é uma exceção no ordenamento jurídico, com vistas à possibilidade de ser um princípio absoluto, proposição que, pelo referencial teórico adotado, descartou-se de pronto, visto que para a teoria dos princípios de Robert Alexy inexistem, por óbvio, princípios absolutos. Ainda, nesta esteira, analisou-se outro instituto afeto ao tema: a autonomia e sua necessária imbricação com a dignidade humana. Ainda, neste trabalho, analisaram-se os princípios reitores do direito penal que advêm, implícita ou explicitamente, da dignidade humana. Depois, nesta mesma seara, analisou-se o contexto da autonomia anteriormente mencionada, mas, agora, pela lupa do direito penal, ladeada pelo fenômeno do paternalismo jurídico e, assim, em certos contornos, sua (im)possibilidade visto a diminuição na esfera de liberdade/autonomia do individuo. Depois, nesta senda, analisou-se o consentimento do ofendido na dogmática penal, assim como seus reflexos e imbricações – com destaque para a disponibilidade e indisponibilidade do bem jurídico, bem como a sua função na dogmática penal, ou seja, o acordo e o consentimento. Passada esta construção teórico-dogmática, realizou-se o estudo de caso, excursionando por alguns institutos afetos ao tema, tais como: a objeção de consciência e a liberdade religiosa no ordenamento jurídico pátrio, para ao fim e ao cabo, responder um dos temas centrais desta dissertação. Afinal, qual o limite do consentimento e da autonomia no âmbito jurídico pátrio?

This chapter analyzes the impact of location in network evening newscasts. The background surrounding newscasters is one indicator of location. Correspondents appear close to the action by going on location, where they stand before the scene itself. Or they can appear surrounded by the technology needed for direct transmission. Sitting in front of a simple backdrop or a typical TV studio set with a desk and chairs produces the impression of distance from events. Studio shots position the anchor at a vantage point for observing events dispassionately. The placement of the camera can also produce an impression of viewing newscasters up close or from a distance. Two main changes in the visual vocabulary of location were observed. Through a quarter century beginning in the 1960s, cameras moved in much closer on the faces of newscasters, conveying visually a sense of their proximity to the audience. Close-ups helped collapse the distance between the viewer and especially anchors. The other change involved the backgrounds. In the 1960s network news style amounted to a series of moderate shots of talking heads on a bland set. By the 1990s reporters began to appear on location more often than on any other backdrop.

Standard accounts of gamelan’s internationalization focus on the growth of gamelan as an ‘ethnic ensemble’ in university and community settings, in touring gamelan troupes, and in intercultural abduction. To complicate this narrative, this chapter examines the Polish composer-pianist Leopold Godowsky and the American composer Henry Eichheim, who approached gamelan to convey impressions of a distant land in the manner of the travelogue, and the place of gamelan in the development of universalist musical theories and practices in American early-twentieth-century educational settings. During this period, audiences were rarely exposed directly to gamelan music; instead they experienced distant approximations or interpretations.

The period of about a year beginning late in 1797 was the high point of the whole decade, and indeed of all European history until 1848, in the matter of international agitation stirred up by the revolutionary-democratic movement. This chapter attempts to recapture this moment of excitement, and to offer an impression of the movement as a whole before following it again in separate countries. Events happened so swiftly, with so little central direction, and yet with so many immediate repercussions over hundreds and thousands of miles, that no plan of exposition can do justice to the reality, which is best seen, though elusively, in any number of chain reactions. For example, in March 1798 the French occupied the Swiss city of Bern and seized its famous “treasure” of some 6,000,000 livres in coin. The money was used to help finance Bonaparte's expedition to Egypt, which in turn was directed in part against the British in India, where the Earl of Mornington was at war with Tipu Sultan who considered himself an ally of the French Republic.

This chapter provides a bird’s eye view of the main numerical particle methods used in the kinetic theory of fluids, the main purpose being of locating Lattice Boltzmann in the broader context of computational kinetic theory. The leading numerical methods for dense and rarified fluids are Molecular Dynamics (MD) and Direct Simulation Monte Carlo (DSMC), respectively. These methods date of the mid 50s and 60s, respectively, and, ever since, they have undergone a series of impressive developments and refinements which have turned them in major tools of investigation, discovery and design. However, they are both very demanding on computational grounds, which motivates a ceaseless demand for new and improved variants aimed at enhancing their computational efficiency without losing physical fidelity and vice versa, enhance their physical fidelity without compromising computational viability.

Why do some military and rebel groups commit many types of violence, creating an impression of senseless chaos, whereas others carefully control violence against civilians? A classic catch-22 faces the leaders of armed groups. Leaders need large groups of people willing to kill and maim—but to do so only under strict control. How can commanders control violence when fighters who are not under direct supervision experience extraordinary stress, fear, and anger? This book argues that discipline is not enough in wartime. Restraint occurs when fighters know why they are fighting and believe in the cause—that is, when commanders invest in political education. Drawing on evidence about state and non-state groups in El Salvador, and extending the argument to the Mano River wars in Liberia and Sierra Leone, the book shows that investments in political education can improve human rights outcomes even where rational incentives for restraint are weak—and that groups whose fighters lack a sense of purpose may engage in massive violence even where incentives for restraint are strong. It concludes that high levels of violence against civilians should be considered a “default setting,” not an aberration.

Whitehead’s accounts of perception are arguably amongst his most important philosophical legacies. His notions of ‘causal efficacy’, ‘presentational immediacy’, and ‘symbolic reference’ offer a direct challenge to the various schools of thought derived from Hume and Kant, in which causation is seen as a pale derivation from the ‘sensationalist’ vivid impressions of immediate atomic sense-data presented to consciousness. Whitehead ties his account of perception not only to a certain conception of causality and time, but also to a generalized or originary account of symbolism. Originary symbolism is the power to affect or be affected, an exposure to what happens as the condition not just for language, experience, or even God in Whitehead’s sense, but for all becoming and life.This critique of ‘natural perception’ and the generalization of an ‘originary’ differential structure is also taken up and developed in great detail and complexity in the work of the French philosopher Gilles Deleuze. Contrasting Whitehead’s account of originary symbolism with Deleuze will enable the drawing out of some of the radical innovations and variations of the process view with regard to perception and life.

This chapter reviews the effects of family variables on spoken language in the largest, longitudinal multisite study of the effects of cochlear implants on young deaf children’s development. Data published to date on 188 deaf and 97 hearing children indicate that parents report high levels of context-specific parenting stress and less sensitivity during parent–child interactions and use fewer higher-level language techniques. Children’s language was related to higher rates of behavior problems, which were associated with higher parenting stress. After implantation, children made impressive gains in spoken language, and these were directly related to maternal sensitivity and use of facilitative language techniques. Our results indicated that cochlear implantation should be accompanied by parenting interventions that increase sensitivity and use of higher-level language strategies and foster a stronger parent–child relationship.

Direct evidence for Sabina’s activities as Augusta in and around Rome is disappointing. Although inscriptions suggest some (limited) benefactions by the empress, the most conspicuous expression of Sabina’s heightened status comes from the Rome mint, which produced an impressive series of original images publicizing the empress’s imperial virtues. Changing titulature and hairstyles on Sabina’s Rome coins help establish a relative chronology and an understanding of the intended messages. The provincial coin issues bearing Sabina’s portrait are harder to assess: on their reverses their subject matter overlaps significantly with types showing the emperor. The regime also offered ever-changing sculptural images of Sabina. On both coins and sculptures, this era’s portrait artists, generally abandoning naturalism, pictured the middle-aged empress as a young serene beauty. The chapter also quantifies Sabina’s assimilation to specific goddesses in the eastern inscriptions, and seeks to understand how eastern communities balanced public honors for Hadrian, Sabina, and Antinoös.

AbstractThis chapter describes the interactions and intersections between film experience and historical experience. The first section introduces the phenomenological theories underpinning the notion of film experience and applies them to the historical film. Focusing on concepts of embodied film perception, it discusses the spectator’s impression of making direct contact with a film’s historical world. This imaginary contact with history bears similarities to Frank R. Ankersmit’s theory of historical experience, which is examined in the second section. The interconnections between Ankersmit’s concept and Vivian Sobchack’s phenomenological theory of film experience are considered in greater depth in the third section. The aim is to develop a concept of histospheres in which sensuous and cognitive perceptions are fused into a unified cinematic experience of history.

AbstractThis case addresses the challenge of leadership succession in a highly respected master’s program at a university in Australia. The director, who was also the program’s lead professor, was due to retire, and the distinctive nature of the program made it particularly difficult to find a suitable replacement. To complicate the challenge, the university’s central administration was not supportive of that master’s degree, whereas it achieved the highest satisfaction ratings in the university from students and enjoyed good support from industry; the director’s insistence on quality of educational experience resulted in tight control of student admission, fewer students, and lower revenue than competing programs.A highly engaged group of students and alumni took on this challenge, working with the outgoing director to sustain impressive results over a 5-year period.

AbstractThis chapter describes the transformative potential of arts and science collaboration. The aim of the Nordic art and science project “Red Snow—When the Climate Bleeds” which was undertaken in 2014–2016 was to increase people's awareness of the accelerating climate changes we are witnessing in the twenty-first century. This chapter shows how people can be encouraged to take action for the care of our planet and to live in a more sustainable way. The project was centred around an exhibition, consisting of artwork and scientific presentations, established collaboration with students at schools and universities and was implemented in four countries. In order to highlight the urgency of the need for change, the project showed some future scenarios presented by climate researchers. With the use of visual art, music and dance, it was possible to reach a larger audience than science alone could: this opened people's hearts and minds to new knowledge. The chapter concludes that the collaboration between the arts and science is increasingly important. Art can successfully go beyond the mental mindset, and speak directly to the emotions of the audience, and once works of art have made an impression, visitors are generally more open to new knowledge.

AbstractThis contribution offers an insight into the function and problems of the oversight and sanctions mechanisms outlined in the General Data Protection Regulation as they relate to the biobanking context. These mechanisms might be considered as meta-mechanisms—mechanisms relating to, but not consisting of, substantive legal principles—functioning in tandem to ensure biobank compliance with data protection principles. Each of the mechanisms outlines, on paper at least, comprehensive and impressive compliance architecture—both expanding on their capacity in relation to Directive 95/46. Accordingly, each mechanism looks likely to have a significant and lasting impact on biobanks and biobanking. Despite this comprehensiveness, however, the mechanisms are not immune from critique. Problems appear regarding the standard of protection provided for research subject rights, regarding the disproportionate impact on legitimate interests tied up with the biobanking process—particularly genomic research interests—and regarding their practical implementability in biobanking.

AbstractRecent deep-learning models have achieved impressive predictive performance by learning complex functions of many variables, often at the cost of interpretability. This chapter covers recent work aiming to interpret models by attributing importance to features and feature groups for a single prediction. Importantly, the proposed attributions assign importance to interactions between features, in addition to features in isolation. These attributions are shown to yield insights across real-world domains, including bio-imaging, cosmology image and natural-language processing. We then show how these attributions can be used to directly improve the generalization of a neural network or to distill it into a simple model. Throughout the chapter, we emphasize the use of reality checks to scrutinize the proposed interpretation techniques.

This chapter discusses the nexus between digital networks and neoliberal transformations since the 1980s. We describe how on social media, people orient around a variety of metrics in order to build and display their ‘human capital’, projecting their preferred electronic doubles of themselves in order to gain desired recognition from others, and in many cases to network and showcase a ‘professional’ identity directly in the interests of career advancement. We discuss this in light of a theory of ‘neoliberal impression management’, which we introduce in reference to the ideas of Erich Fromm, Erving Goffman, and Michel Foucault. In our theory of neoliberal impression management, a person forges a spectacular self through which their actions and interactions are displayed in ‘public’ view. In doing this, they also amass publicly viewable metrics (likes, shares, followers, etc.) that suggest an ‘objective’ value. This cultural development moves toward self-centeredness, narcissism, and attention-seeking, and away from genuine concern for others and connection with them. This feeds the potential for numbness to – if not outright acceptance of – political cruelty and injustice.

Abstract Interpreting Bernard Williams’s ethical philosophy is not easy. His style is apparently direct yet argumentatively inexplicit and allusive. He is moreover committed to evading philosophical “isms.” This gives the impression that his philosophy is a web of interrelated commitments where none has priority. Against this impression, in this chapter it is proposed that there is a single, unchanging root conviction from which Williams’s ethical philosophy grows. This is argued by reference to three signature theses: internal reasons, the relativism of distance, and the porous borders of philosophy and history. These are represented as the fruits of the conviction that the constraints of universal rationality seriously underdetermine how one should live. This vision of the human condition constitutes the inexplicit yet fundamental presupposition beneath Williams’s ethical philosophy. The object of this root conviction is labeled ethical freedom and thus Williams is portrayed as a philosopher of ethical freedom.

This chapter explores direct speech representation in Early Modern English prose fiction and witness depositions. The focus is on the preface position in direct speech turns—that is, the very first position at speech onset. The aim is to discover how the beginning of direct speech was signalled in the presence or absence of speech-external quotatives, at a time when transitions in voice were not yet consistently marked by punctuation. I investigate similarities and differences between the two text types, drawn from A Corpus of English Dialogues 1560–1760, to understand how an impression of direct speech was created for literary purposes as opposed to (re)constructed in a legal context. This study thus provides new insights into the relationship between the construction and reconstruction of speech and thereby contributes to the research agenda of enhancing our understanding of speech (re)presentation during past periods of the English language.

The automotive industry is very competitive and companies are spending enormous amounts of resources on the development of new cars. The success of a new model is highly correlated to how well the designers and engineers have been able to blend features, functionality, quality and design to bring an attractive car to a certain segment of the market at the right time. Furthermore, as modern manufacturing techniques have enabled most manufacturers to offer standard features in their cars, the design has become a major selling point and one of the key factors for the ‘image’ associated with a company. However, the image, or form impression of a car, stated in natural language, is subtle and difficult to directly relate to concrete design parameters. With few tools to address this issue, designers are left to rely on their experience and sensitivity to current trends in order to meet the customer expectations for a new model. The purpose of the method reported in this paper is to provide a foundation for a design support system, which can help designers visualize and validate the complex relationship between form impressions and design parameters. This was achieved by expressing form impressions in natural language as sets of 10 weighted attributes. 14 design parameters were established to describe the basic shape of a car and data on the form impression for 31 different shapes was collected via a survey designed by the Taguchi method. Factor analysis was performed to extract correlated factors and eliminate the overlap of meaning between attributes. A neural network, able to relate form impressions expressed in these factors to basic proportions of a car, was created, trained and used to generalize design parameters corresponding to any form impression presented to it. Finally, a 3D-model with the desired form impression was automatically created by the CAD-system outlined in this paper. These results show that this method can be used to create a design support system, which has a sensibility to the form impressions various shapes will give.

This paper presents a new method for the manipulation of a given CAE domain in view of VR based explorations that enables engineers to interactively inspect and analyze a linear static domain. The interactions can ideally be performed in real-time in order to provide an intuitive impression of the changes to the underlying volumetric domain. We take the approach of element masking, i.e. the blending out of computations resulting from computational overhead for inner nodes, based on the inversion of the stiffness matrix. This allows us to optimize the re-simulation loop and to achieve real-time performance for strain and stress distributions with immediate visualization feedback caused by interactively changing boundary conditions. The novelty of the presented approach is a direct coupling of view dependent simulations and its close linkage to post-processing tasks. This allows engineers to also inspect the changes of the stress field inside of the volume during, e.g. cross sectioning.

Reliable, high power CO2, YAG, and Ar ion lasers are common medical instruments, having become the tool of choice in surgical applications as delicate as the repair of detached retinas and as coarse as the removal of polyps from the colon. For these lasers, the destruction of the selected tissue is a thermal process. The laser is simply a convenient means for delivering a sufficient amount of power to the required area to effect pyrolysis. Although obviously quite useful, it belies the impression of the laser as a superbly precise instrument since thermal decomposition is a rather dirty and crude process in terms of the reaction products and the inability to prevent damage to adjacent tissue. If, however, the excitation wavelength is lowered to the UV region below ca. 300 nm the decomposition mechanism changes. Instead of being limited to exciting vibrations and rotations in the exposed material, radiant energy is deposited into the covalent bonds of the biopolymer molecules, causing their direct fragmentation.

Professional sports in North America has become, in recent years, a billion-dollar industry, where players are slowly becoming the industry's biggest assets. Through players, US national leagues have managed to grow in recent years by about 60%, but with this increase, player salaries have begun to become more competitive in the market, managing to reach impressive amounts in a short period of time. This research seeks to investigate the direct relationship between two models of the salary cap - hard cap salary and soft cap salary and the direct relationship with the success of teams in American national leagues in recent seasons. Also based on this study, the aim is to compare the leagues that use a hard cap salary model (NHL), with the leagues that use a soft salary model (NBA), and which of the two are more competitive from a professional and economic point of view.

The creep damage evolution in multi-pass welds is believed to be influenced by the variation of creep rates from the weld to the base metal and through the HAZ. Material heterogeneity in a multi-pass weld leads to a non-uniform stress distribution resulting in non-uniform evolution of creep strains with strain localisation. Also, a non-uniform stress distribution may lead to highly multiaxial stress states in the weld resulting in a lower creep ductility. Since creep damage in metallic components is influenced by creep strain rate and creep ductility of the material amongst other factors, creep inhomogeneity in a weldment may significantly affect creep damage accumulation. Therefore, in order to predict creep behaviour of a multi-pass weld, it is important to take into account the gradation of creep deformation properties through the weld HAZ. Impression creep tests are useful in revealing localised creep properties in a material, where test results can be directly correlated to uniaxial creep tests. In this paper, a 2D finite element model of a multipass 316H weld with three different material sections (weld, HAZ, parent) is used to demonstrate the effects of creep deformation mismatch on stress and strain distributions. The paper also describes a series of impression creep tests planned and being conducted on an ex-service 316H weldment from a power plant steam generator with specimens taken from locations in the HAZ and at varying proximities to the weld fusion line. One specimen from the far away base metal and one from the weld centerline were also taken to serve as reference since the uniaxial creep deformation properties for the weld and the base material are known from uniaxial creep tests. By comparing the minimum creep rates for the HAZ specimens against the reference specimens from the weld and the base metal, Norton’s law creep coefficients and stress exponents will be derived for the HAZ specimens thereby revealing the gradation of creep deformation properties as a function of distance from the weld fusion line.

Considering the fact that a kindergarten teacher is the only per- son in charge of the whole teaching process and therefore he/she has insight into children’s prior knowledge, possibilities and achievements, using directed activ- ities in teaching is particularly suitable for the integrative approach. Children’s environment is an inexhaustible source of knowledge, impressions, emotions and experiences. It encourages children to constantly enrich their knowledge and ex- periences, to explore, discover and develop their thinking and competences. Chil- dren should become familiar with the characteristics of objects and phenomena from their surroundings using the activities such as observing, comparing, prac- tical work, testing hypothesis, playing constructive games. Given that children consider their environment in an integrative and synthetic way, as being a unique entity, the interdisciplinary approach in teaching Environmental Education of- fers different ways of correlating and integrating different subjects. This paper presents and analyses the possibilities of planning and organizing directed activities, proposed by Methodology of Environmental Education and Methodology of Teaching Basic Mathematics Concepts, which include the inte- grative approach and correlation; the activities are illustrated with some concrete examples of teaching activities. It has been proved that integrative approach in teaching contributes to acquiring knowledge and developing both children’s and teachers’ thinking ability, creativity, physical, conative and social competences.

This paper explores a particular job creation channel during a resource boom, using Mongolia as a case study. Resource booms can lead to impressive growth rates in resource-rich developing countries. The paper examines the link between resource booms triggered by new resource projects and FDI inflows into the non-resource sector on one hand, and FDI and job creation on the other. Its analysis focuses explicitly on the non-resource sector, where the positive economic effects of FDI are more pronounced than in the extractive sector.

The article investigates functional techniques of extralinguistic expression in multimedia texts; the effectiveness of figurative expressions as a reaction to modern events in Ukraine and their influence on the formation of public opinion is shown. Publications of journalists, broadcasts of media resonators, experts, public figures, politicians, readers are analyzed. The language of the media plays a key role in shaping the worldview of the young political elite in the first place. The essence of each statement is a focused thought that reacts to events in the world or in one’s own country. The most popular platform for mass information and social interaction is, first of all, network journalism, which is characterized by mobility and unlimited time and space. Authors have complete freedom to express their views in direct language, including their own word formation. Phonetic, lexical, phraseological and stylistic means of speech create expression of the text. A figurative word, a good aphorism or proverb, a paraphrased expression, etc. enhance the effectiveness of a multimedia text. This is especially important for headlines that simultaneously inform and influence the views of millions of readers. Given the wide range of issues raised by the Internet as a medium, research in this area is interdisciplinary. The science of information, combining language and social communication, is at the forefront of global interactions. The Internet is an effective source of knowledge and a forum for free thought. Nonlinear texts (hypertexts) – «branching texts or texts that perform actions on request», multimedia texts change the principles of information collection, storage and dissemination, involving billions of readers in the discussion of global issues. Mastering the word is not an easy task if the author of the publication is not well-read, is not deep in the topic, does not know the psychology of the audience for which he writes. Therefore, the study of media broadcasting is an important component of the professional training of future journalists. The functions of the language of the media require the authors to make the right statements and convincing arguments in the text. Journalism education is not only knowledge of imperative and dispositive norms, but also apodictic ones. In practice, this means that there are rules in media creativity that are based on logical necessity. Apodicticity is the first sign of impressive language on the platform of print or electronic media. Social expression is a combination of creative abilities and linguistic competencies that a journalist realizes in his activity. Creative self-expression is realized in a set of many important factors in the media: the choice of topic, convincing arguments, logical presentation of ideas and deep philological education. Linguistic art, in contrast to painting, music, sculpture, accumulates all visual, auditory, tactile and empathic sensations in a universal sign – the word. The choice of the word for the reproduction of sensory and semantic meanings, its competent use in the appropriate context distinguishes the journalist-intellectual from other participants in forums, round tables, analytical or entertainment programs. Expressive speech in the media is a product of the intellect (ability to think) of all those who write on socio-political or economic topics. In the same plane with him – intelligence (awareness, prudence), the first sign of which (according to Ivan Ogienko) is a good knowledge of the language. Intellectual language is an important means of organizing a journalistic text. It, on the one hand, logically conveys the author’s thoughts, and on the other – encourages the reader to reflect and comprehend what is read. The richness of language is accumulated through continuous self-education and interesting communication. Studies of social expression as an important factor influencing the formation of public consciousness should open up new facets of rational and emotional media broadcasting; to trace physical and psychological reactions to communicative mimicry in the media. Speech mimicry as one of the methods of disguise is increasingly becoming a dangerous factor in manipulating the media. Mimicry is an unprincipled adaptation to the surrounding social conditions; one of the most famous examples of an animal characterized by mimicry (change of protective color and shape) is a chameleon. In a figurative sense, chameleons are called adaptive journalists. Observations show that mimicry in politics is to some extent a kind of game that, like every game, is always conditional and artificial.
