Radiography images are widely utilized in the health sector to recognize the patient health condition. The noise and irrelevant region information minimize the entire disease detection accuracy and computation complexity. Therefore, in this study, statistical Kolmogorov–Smirnov test has been integrated with wavelet transform to overcome the de-noising issues. Then the cat swarm-optimized deep belief network is applied to extract the features from the affected region. The optimized deep learning model reduces the feature training cost and time and improves the (...) overall disease detection accuracy. The network learning process is enhanced according to the AdaDelta learning process, which replaces the learning parameter with a delta value. This process minimizes the error rate while recognizing the disease. The efficiency of the system evaluated using image retrieval in medical application dataset. This process helps to determine the various diseases such as breast, lung, and pediatric studies. (shrink)

C’est grâce à son essai Politische Romantik, publié en 1919, que Carl Schmitt fait une entrée remarquée sur la scène intellectuelle allemande. L’ouvrage se présente comme une charge systématique et radicale contre la tradition allemande du « romantisme politique », et fut vivement discuté dans les années qui suivirent sa publication. Mais aujourd’hui il se trouve relégué parmi les œuvres de jeunesse de Schmitt et reste rarement étudié par la recherche, qui le lit au mieux comme une belle contribution à (...) l’histoire culturelle du xixe siècle.Pourtant, une étude approfondie de l’essai, ainsi que du contexte historique dans lequel il s’insère, fait apparaître que ce n’est pas dans une telle perspective que Politische Romantik manifeste toute sa portée : bien plus qu’une étude historique, cet essai constitue un élément de réponse à la crise du conservatisme allemand tel qu’il apparaît dans l’après-guerre. Le rejet du « romantisme politique » marque la rupture de Schmitt avec l’idéal « apolitique » des intellectuels allemands de l’époque, et par là constitue le premier moment du projet schmittien, tel qu’il se verra développé de manière croisée dans son étude sur le catholicisme et sa Théologie politique.

Né du culte militaire et d’un coup d’État raté, le « chavisme » est devenu un phénomène politique. Après avoir survécu au coup d’État de 2002, il a commencé à coloniser l’État dans un processus progressif mais continu dans lequel est apparu un nouveau type de militarisme de gauche que l’on pourrait appeler le « comandantismo ». Ce régime est entré en crise avec la mort de Chavez et la chute des prix du pétrole. Avec Maduro, son successeur, une tentative (...) de réforme a connu le succès dans la lutte pour le pouvoir mais a échoué à obtenir des changements mettant fin à un désastre systémique qui a commencé il y a plus de dix ans.

RESUMENEl desarrollo embriológico es un fenómeno que ha inspirado la especulación filosófica desde temprano en la historia del pensamiento. Desde los tiempos de Aristóteles dos modelos conceptuales antitéticos se han utilizado tradicionalmente para comprender la embriogénesis: o el embrión posee ya una forma o estructura, o ésta se forma de nuevo en cada generación. Nuestro objetivo en este artículo es mostrar que el contraste entre la posición preformacionista y epigenética persiste a pesar de los formidables avances teóricos y experimentales de (...) la biología del desarrollo contemporánea. El preformacionismo y la epigénesis han perfeccionado constantemente sus posiciones en el curso de la historia con el fin de responder a los retos conceptuales de la época. Este continuo proceso de transformación ha dado lugar a una convergencia parcial entre las dos posiciones. Sin embargo, vamos a argumentar que, a pesar de los esfuerzos por conciliar ambas posturas, esta antinomia, que se erige como una de las más fundamentales de la biología, no será fácil de superar. ABSTRACTThe process of development of the embryo has inspired philosophical speculation since the advent of Western thought. Since the time of Aristotle two antithetical conceptual models have traditionally been used to understand embryogenesis: either form or structure is preformed in the embryo or it is newly formed with each generation. Our aim in this article is to show that the contrast between the pre-formationist and epigenetic positions persists despite the formidable theoretical and experimental advances of contemporary developmental biology. Pre-formationism and epigenesis have constantly refined their positions in the course of history in order to answer the conceptual challenges of each epoch. This process of continuous transformation has resulted in a partial convergence of the two positions. However, we shall argue that, despite the partial successes of this process of continuous convergence, one of the most fundamental antinomies in biology persists. (shrink)

Background The integration of artificial intelligence (AI) in radiography presents transformative opportunities for diagnostic imaging and introduces complex ethical considerations. The aim of this cross-sectional study was to explore radiographers’ perspectives on the ethical implications of AI in their field and identify key concerns and potential strategies for addressing them. Methods A structured questionnaire was distributed to a diverse group of radiographers in Saudi Arabia. The questionnaire included items on ethical concerns related to AI, the perceived impact on clinical (...) practice, and suggestions for ethical AI integration in radiography. The data were analyzed using quantitative and qualitative methods to capture a broad range of perspectives. Results Three hundred eighty-eight radiographers responded and had varying levels of experience and specializations. Most (44.8%) participants were unfamiliar with the integration of AI into radiography. Approximately 32.9% of radiographers expressed uncertainty regarding the importance of transparency and explanatory capabilities in the AI systems used in radiology. Many (36.9%) participants indicated that they believed that AI systems used in radiology should be transparent and provide justifications for their decision-making procedures. A significant preponderance (44%) of respondents agreed that implementing AI in radiology may increase ethical dilemmas. However, 27.8%expressed uncertainty in recognizing and understanding the potential ethical issues that could arise from integrating AI in radiology. Of the respondents, 41.5% stated that the use of AI in radiology required establishing specific ethical guidelines. However, a significant percentage (28.9%) expressed the opposite opinion, arguing that utilizing AI in radiology does not require adherence to ethical standards. In contrast to the 46.6% of respondents voicing concerns about patient privacy over AI implementation, 41.5% of respondents did not have any such apprehensions. Conclusions This study revealed a complex ethical landscape in the integration of AI in radiography, characterized by enthusiasm and apprehension among professionals. It underscores the necessity for ethical frameworks, education, and policy development to guide the implementation of AI in radiography. These findings contribute to the ongoing discourse on AI in medical imaging and provide insights that can inform policymakers, educators, and practitioners in navigating the ethical challenges of AI adoption in healthcare.

When education is jointly managed by a workplace and academia, causal mechanisms in the culture, structure and agency of these two contexts may unintentionally generate discourse that conveys conflicting messages for learners regarding some of the priorities of the profession. Using the concepts of culture, structure and agency as they are used in critical realism to analyse the discourse generated in two teaching and learning contexts (a radiography division in a university and a radiography workplace in a large (...) state tertiary academic hospital), this paper attempts (i) to identify possible causal mechanisms that generated discourse concerning the role and value of writing competency for radiographers, such that this discourse possibly influenced learners not to be motivated to improve their writing competency to their lecturers’ satisfaction; and (ii) to suggest what practices and influences might successfully generate an alternative emancipatory discourse. Drawing on Margaret Archer’s (1995) morphogenetic approach, the paper argues that the radiography lecturers have the primary agency to address this unsatisfactory situation, as it is through their interaction – both as a team and with other relevant stakeholders – that an alternative emancipatory discourse may be generated.

A 10 kHz pulsed X-ray generator utilising a hot-cathode triode in conjunction with a new type of grid control device for controlling X-ray duration is described. The energy-storage condenser was charged up to 70 kV by a power supply, and the electric charges in the condenser were discharged to the X-ray tube repetitively by the grid control device. The maximum values of the grid voltage, the tube voltage, and the tube current were −1.5 kV, 70 kV, and 0.4 A, respectively. (...) The duration of the flash X-ray pulse was primarily determined by the time constant of the grid control device and the cut-off voltage of thermoelectrons. The X-ray duration was controlled within a region of less than 1 ms; the X-ray intensity with a pulse width of 0.27 ms, a charged voltage of 70 kV, and a peak tube current of 0.4 A was 0.92 μC kg −1 at 0.5 m per pulse. The maximum repetition rate was about 10 kHz, and the size of the focal spot was about 3.5×3.5 mm. (shrink)

The “Radiography of the Teaching of University Entrepreneurship in Mexico” is situated within the context of the necessity to comprehend and enhance the pedagogical practices associated with entrepreneurship in Mexican universities. This context encompasses a global examination of entrepreneurship and its prevailing trends, as well as a detailed analysis of the entrepreneurial landscape in Mexico. The principal objective of this study is to conduct a comprehensive examination of the pedagogical approaches employed in higher education institutions (HEIs) in Mexico with (...) regard to the teaching of entrepreneurship. The objective is to establish a unified approach to entrepreneurship teaching, identify the most effective pedagogical tools for fostering an entrepreneurial mindset, and disseminate the requisite technical knowledge among educators to facilitate their integration into the classroom. The methodology employed begins with a review of secondary sources to provide a detailed overview of the global and Mexican entrepreneurship landscapes, as well as the current state of entrepreneurship education in higher education institutions (HEIs). In conclusion, the Delphi technique is employed to conduct interviews with experts directly involved in the teaching of entrepreneurship in various HEIs, with the objective of collecting and synthesizing their opinions on the subject matter. The research yielded a “Teaching Model of Entrepreneurship in the University,” which is based on the identified approaches, models, and methodologies. The teacher plays a pivotal role in the teaching of entrepreneurship in higher education institutions (HEIs). The findings indicate that in Mexico, the probability of success or opportunity for entrepreneurs is significantly influenced by the material conditions of the individual, which are shaped by their social stratum and geographical location. Furthermore, data indicates that all HEIs endeavor to impart instruction on entrepreneurship. However, due to significant disparities between private and public institutions, smaller or more remote ones may lack the capacity and resources to do so effectively. Therefore, this results in heterogeneity in the teaching of entrepreneurship, which could condition the chances of success for those wishing to become entrepreneurs. Consequently, the necessity was identified for all entrepreneurship teachers in HEIs in Mexico to be able to achieve a robust and comprehensive process of teaching entrepreneurship, whereby students can develop their entrepreneurial skills at an early stage, as well as the creation of companies at a later stage.

Physiotherapy raises serious bioethical questions that are far too little discussed. Concerns include the lack of a clearly defined end point, the closeness of interaction between therapist and patient, the patient’s own share of responsibility, and the common failure to refer patients for rehabilitation.Physiotherapy has evolved dramatically in recent years, to the point where it is now a major healthcare profession offering assessment, diagnosis and treatment for a wide range of conditions, from sports injuries to rehabilitation for major injuries and (...) diseases. According to the World Confederation for Physical Therapy, “Physical Therapy is providing services to people and populations to develop maintain and restore maximum movement and functional ability throughout the lifespan” .1However, almost uniquely among the healthcare professions, physiotherapy has aroused little or no philosophical interest or engagement. This is surprising, because some of the salient features of physiotherapy raise interesting and to some extent novel problems in ethics. There are, it is true, some papers on ethically related themes,2–5 but in comparison with the size of the discipline and the complexity of the problems, the profile of physiotherapy in bioethics is worryingly low.A first problem is that unlike many areas of medicine—surgery, for example, or radiography or obstetrics and gynaecology—physiotherapy has no obvious end point. In medicine, the end points of treatment are generally well defined, with only a few exceptions, such as plastic surgery or psychiatry. It is my impression that physiotherapy, with few exceptions, does not operate with the concept of end points. Although what physiotherapy aims at is clear, the point at which the aims are achieved is uncertain. For example, in many cases the patient would go on benefiting from sessions of physiotherapy, perhaps with diminishing returns but still with …. (shrink)

This article introduces the Special Issue on cameraless photography and the translation of Georg Christoph Lichtenberg’s treatise on electrical figures. It summarizes previous discussions on cameraless photography, namely those by Geoffrey Batchen and suggests relating the photogram to current post-lenticular technologies such as radiography, digital scanning or machine vision. It outlines the emergence of cameraless imaging in late eighteenth- and early nineteenth-century scientific research, taking Lichtenberg’s figures as an emblem of automatically generated images situated between duration and instantaneity, between (...) image making and measurement, between nature and culture.

Health science students frequently experience ethical dilemmas on clinical placements, yet ethics education rarely prepares students with the ethical leadership skills required. The Leadership in Ethical Practice (LEP) program is an ethics education resource designed to enhance health science students’ knowledge and skills in ethical leadership to prepare them for clinical placements and future professional practice. This qualitative study aimed: to explore the nature of students’ ethical leadership goals; determine whether a specific, measurable, achievable, relevant, and time-bound (SMART) format was (...) an effective tool for students to create ethical leadership goals; and identify any changes in students’ pre- and post-self-ratings of ethical leadership knowledge following the LEP program. Eighty-two diagnostic radiography students from the University of Sydney participated in the study. Inductive and deductive qualitative content analysis (Elo & Kyngas, 2008) were used to explore students’ goals. Descriptive statistics were used to investigate students’ pre- and post-self-ratings. Four themes emerged from students’ goals: initiative, competence, and courage in ethical reasoning; communicating ethical stories through listening, questioning, and connecting; reflecting and growing as an ethical leader; and safe practice and person-centred outcomes. SMART goal format elements were evident in 61% of students’ goals. Students' ethical leadership self-ratings showed positive changes after participating in the LEP program. Findings indicated students planned to further develop ethical leadership skills during clinical placements and future professional practice. This study demonstrated the ethics education approaches used within the LEP could assist health science students to apply ethical leadership in future clinical practice. (shrink)

Ce livre traite de l'image, mais aussi, plus generalement, de la copie, du double, de la representation, du calque, du sosie... La philosophie, a juste titre, a mis en garde contres ces si dangereux reflets. Ne doit-on pas preferer ce qui est a ce qui l'imite ou le mime? Mefions-nous des leurres! Cependant, on est revenu sur cette seculaire et injuste condamnation. La technologie moderne a peu a peu sauve celle qu'on avait trop inferiorisee et eloignee. Et quelle victoire! L'image (...) numerique, donc celle de synthese, l'arrache a une servitude que les philosophes classiques et meme plus modernes avaient scellee. L'electro-optique, la tomodensitometrie (scannographie), l'holographie, entre autres, multiplient les prouesses liberatrices. Dans le passe, la photographie, voire la radiographie avaient deja ebranle les anciennes positions. La guerre commencait. L'imagerie deferle donc, ainsi que l'industrie noire des contrefacons, des plagiats, des pseudo-repliques, du pastiche. Les trucages et la fraude. Mais ou situer aujourd'hui le vrai et le faux? Comment distinguer le modele et son equivalent? Les vieilles frontieres, comme on le montrera, s'estompent. Quel branle-bas et quelle fete aussi! On a voulu prendre acte de cette nouveaute. Hatons-nous, malgre le danger de nous y perdre, d'engager la philosophie que nous croyons reticente dans ce tourbillon. (shrink)

La restitution des artefacts pillés lors des conquêtes coloniales ou abritées dans les musées « coloniaux » suscite des réactions antagoniques. Faut-il « tuer » le modèle du musée ethnographique, comme le préconise le président du Mali, ou bien purifier les collections témoins de pratiques génocidaires, en les radiographiant ou les cachant dans les réserves muséales, à l’abri des regards critiques? La complicité entre le pouvoir académique et le principe d’inaliénabilité de la propriété muséologique rendent le processus de restitution particulièrement (...) lent. Pour éviter que la restitution soit récupérée, des réponses rapides ont été conçues pour mieux correspondre aux imaginaires et pratiques de la jeunesse africaine: musée numérique, muséologie critique, institutions de culture populaire et restitution « en mode rapide ». Plutôt que de se focaliser sur des objets iconiques, la restitution en mode rapide cherche à revisiter l’ingéniosité traditionnelle précoloniale pour développer de nouvelles techniques, de nouvelles œuvres d’art et de nouveaux objets à finalité sociale et spirituelle.

Centré sur la Roumanie et basé sur l'étude d'un corpus de trois quotidiens nationaux, il analyse les orientations du discours développé par la presse de cet état dans les jours qui ont suivi cet événement dramatique. Il montre que le mode de traitement journalistique développe une vision fataliste et tragique de l'événement. Il met en (...) évidence les stratégies «émotionnalisantes» qui sont mises en oeuvre. Axées sur les victimes roumaines de l'attentat, elles sont observables dans les trois journaux tant sur le plan verbal qu'iconique. L'article souligne enfin que l'événement à portée internationale des attentats de Madrid ouvre pour les journalistes roumains l'opportunité de dresser, au plan interne, une radiographie sociopolitique assez sévère, tout en mobilisant des mythes et des archétypes culturels qui confortent les valeurs nationales roumaines.This article is one of a comparative study on the international media coverage of the attack in Atocha train station in Madrid in March 2004.

Cet ouvrage ne présente pas un système complet et cohérent, méritant le nom d'une philosophie du droit international. Une telle entreprise serait à la fois trop vaste face à une société internationale de haute complexité et aussi un peu anachronique au regard de la perte de foi dans les systèmes trop parfaits et dès lors trop réductifs. C'est plutôt une série de réflexions personnelles sur les points de droit international qui m'ont paru importants au fil des années d'étude de cette (...) matière, que je veux ici présenter. Si ces points ne s'ordonnent pas en un système, ils ne sont néanmoins pas jetés sur le papier au hasard. Ces réflexions ont ceci en commun qu'elles tentent de serrer de plus près les aspects ordonnateurs et structurants du droit international, en un mot, ses chevilles ouvrières aux points charnière ou ses voûtes névralgiques. Ces réflexions s'ordonnent autour de trois axes. Dans une première partie, il s'agit de dégager quelques caractéristiques fondamentales du droit international, qui expliquent et imprègnent ses applications. Après une discussion des types possibles de droit international et de leur réalisation dans l'histoire, il est question des grandes phases d'évolution qu'a connues le droit international depuis le temps de Grotius. Ensuite, les caractéristiques propres des sources du droit international (les sources constituant une espèce de radiographie de tout ordre juridique) sont examinées. Parmi les autres caractéristiques de la règle internationale, ce sont notamment sa tendance à l'individualisation, à l'ouverture vers les circonstances particulières des espèces, ainsi que les incidences de cette tendance, qui font l'objet de considérations. Enfin, il est question de la règle " tout ce qui n'est pas interdit est permis ", renforcée en droit international par la souveraineté. De sa place et de ses rôles exacts dépend la nature et la force de l'ordre juridique en question. Dans une seconde partie, ce sont les relations multiples du droit et de la politique qui font l'objet d'analyses. Si la politique est un facteur essentiel de vie et de réalisation de tout droit (et aussi une menace pour lui), il en est à plus forte raison ainsi en droit international, où les deux branches, droit et politique, sont particulièrement proches. L'analyse ne se borne pas à des relations stéréotypées, mais tente de dégager en catégories d'espèces une multitude de pesées réciproques entre les deux branches, dans leurs vertus centripètes et centrifuges. Enfin, dans une troisième partie importante, c'est une série de notions juridiques cardinales qui forme l'objet des réflexions. Il s'agit du bien commun ; de la justice ; de la sécurité juridique ; de la réciprocité, de l'égalité et de la proportionnalité ; de la liberté ; de la morale et de la morale sociale ; de la volonté dans ses rapports avec la raison ; de la sanction. Il s'agit de voir quelle est la configuration que l'expérience juridique générale a donnée à ces notions et par la suite d'examiner comment elles peuvent s'insérer et agir au sein du droit international au regard des spécificités de la société internationale, avec quelles analogies mais aussi avec quelles altérations ou adaptations. C'est ainsi qu'on peut dégager ce degré d'orientation juridique inhérent au " droit international " dans ses forces et ses faiblesses. (shrink)

Introduction: Necrotizing enterocolitis (NEC) is an inflammatory condition caused by infectious agents with a background of immaturity of local defense mechanisms and hypoxic-ischemic damage to the intestinal mucosa. Plain abdominal radiography can be used to examine this condition. The results of diagnostic imaging of the neonatal gastrointestinal tract have relatively limited accuracy, and limit improvements in diagnostic efforts and determine the severity. The results of the examination can also be used with ultrasound. This study aims to analyze the correlation (...) of NEC examination using plain radiography and ultrasound. Methods: This type of research uses a retrospective cohort study. The subjects of the study were 39 patients who underwent plain radiography and ultrasound examinations related to NEC conditions. The data source for this study is secondary data obtained through an intermediary media, namely PACS. The secondary data source for this study is data that has been recorded at the Radiology Installation of Hasan Sadikin Hospital in the period January 2023-June 2024. The Spearman correlation test was used to test the hypothesis of a correlation between NEC examinations using plain radiography and ultrasound. Results: The results of the Spearman correlation test showed no significant correlation between NEC examination using plain radiographs and USG with a correlation coefficient value of 0.138. The findings that can be taken from this study are that there is an increase in grade in patients who undergo USG examination. This finding proves the importance of conducting USG examination to confirm NEC conditions more accurately. Conclusion: There is no significant correlation between NEC examination using plain radiographs and USG. Examination using USG can confirm NEC more accurately, as evidenced by an increase in grade in 43.58% of study subjects. (shrink)

This article analyzes the structure and the aims of the Encyclopaedia. The Encyclopaedia presented itself as an attempt to give a systematic and complete account of all knowledge of its time. By doing this, it really became an intellectual radiography of the Enlightenment, and from that perspective is presented in this article.

“Biography” is a sober, precise and modern word. Like other words formed from a Greek root, it has a competent and knowing air. It makes a good appearance in the summary of reviews, on the platform at conferences, between “biology” and “bibliography,” between “necrology” and “radiography,” in that scientific elite of the lexicon that travels in “business” class from one language to another, always at home in the time belts, hotel lobbies, conference rooms or amphitheaters. Compared with this prosperity, (...) the word “Life” is old-fashioned, a poor relative doomed to retirement homes. In the period between the two wars it disappeared from bookstore windows and book jackets. The hesitations of André Maurois, the author of Aspects de la biographie (1928), are characteristic of a transition: he wavered between La Vie de Disraeli (1927), Ariel ou la vie de Shelley (1923), Prométhée ou la vie de Balzac (1965) and Byron (1930). We sense that the title Vie was on the way out or had to yield to a proper name or an allegorical figure. However, it was a word in good standing, nobly Latin in origin, as great a signore in its class as those Massimi or Colonna who claimed their ancestors were mentioned by Titus Livy. Its genealogy is still more ancient, if we recall that its metonymic and literary meaning in Latin is a translation of the Greek word Bios, which the Hellenes, inventors of the genre and who had a more pedantic use of their language than we do, were content to use up until the end. “Biography,” according to Liddell-Scott, is not found in Antiquity except in a very late neo-Platonian, Damaskios, who put this humorless escogriffe into circulation when twilight was descending on the Roman Empire, between the 5th and 6th centuries A.D., at the dawn of the Middle Ages. It made its entrance into modern languages in the last quarter of the 17th century, when the humanism of the Renaissance was coming to an end, and the Enlightenment was beginning its rise. This late and ill-boding word began a slow ascension, long delayed: it did not come into usage outside the circles of antiquarians until the 19th century. The old word “Life” proudly kept its importance until the ‘20s of our era in the particularly conservative language of titles of works. Its definitive effacement to the profit of “biography” brought that of the word “memoirs” or the word “confessions,” which yielded to “autobiography,” while “hagiography” without being able to impose itself so well in usage, took much gravity and credibility away from the “Lives of the Saints.”.

A la recherche des "images de pensée" (Denkbilder), Walter Benjamin instaure un procédé efficace de correspondance entre rêve et architecture, une idée qu'il tenait du surréalisme. On a pu parler d'oniromancie à l'envers, car son point de départ est matériel : il part des choses, des objets, des lieux, des endroits, des atmosphères pour mettre en lumière leurs qualités irrationnelles. Une telle théorie décrit précisément les relations fantastiques se créant par l'assemblage d'articles luxueux, d'objets d'art anciens, de pièces de collection, (...) de bibelots passés de mode, de colifichets frivoles, de fragments dépareillés, d'images surannées, ou encore d'instruments tombés en désuétude. Tout cela forme un milieu peuplé d'objets et de gens, capable d'engendrer un paysage onirique et conduisant à une expérience agoraphobique, intériorisée. Ici, le spectateur est à la recherche du temps perdu, et les objets sont comme des alambics filtrant la durée. Procédant à la radiographie de la "maison de rêve" (Traumhaus), Benjamin offre un catalogue précis des meubles oniriques qui en hantent les espaces clos. (shrink)

A study of the structural perfection of icosahedral quasicrystalline grains of various alloys and Al-Cu-Fe), grown by different slow solidification techniques was performed using high-resolution diffraction, including recording rocking curves combined with X-ray topography and phase contrast radiography, at a third-generation synchrotron radiation source . For Al-Pd-Mn, additional coherent diffraction and diffuse scattering measurements were also carried out. After evaluating the potentialities of the techniques used, in the light of the criteria defined for crystals, it is shown that the (...) structural perfection of icosahedral quasicrystals is quite comparable with that of metallic crystals but is considerably influenced by either uniform phason strains which can destroy the quasiperiodic long-range order, or by long-wavelength phason fluctuations leading to diffuse scattering. The structural perfection was also found to be extremely variable across the as-grown quasicrystalline grains and to be dependent on the presence and characteristics of inhomogeneities often included in the quasicrystalline matrix. Regarding the grains that we used, it has been impossible to distinguish a clear influence of either the type of alloy or the growth method. It has, however, been noticed that Al-Pd-Mn and Al-Cu-Fe grains appeared less defective than Zn-Mg-RE grains and that the microstructure of these latter grains looks like that of crystals grown by the same technique. Annealing and mechanical polishing effects have also been analysed in the case of Al-Pd-Mn grains. It appeared that annealing improves the quasicrystalline lattice perfection by lowering phason strains insofar as no precipitates are nucleated. Mechanical polishing can introduce defects, located at the external surfaces, having the shape of bands. (shrink)
