  8. Astronomy in the Age of Leonardo.

    NASA Astrophysics Data System (ADS)

    Welther, B. L.

    1997-12-01

    In the 1450s, when Leonardo da Vinci was born, horoscopes were still based primarily on the 13th-century tables developed in the court of Alfonso el Sabio of Spain. By the 15th century European astronomers were computing revised forms of the tables. In Italy, for example, Giovanni Bianchini of Ferrara completed his Tabulae astronomicae in the 1440s. It was finally published posthumously in Venice in 1495. By the 1480s Domenico Maria Novara, a professor of astronomy in Bologna, was publishing annual prognostications of eclipses, conjunctions, and other celestial phenomena. Against this background of traditional astronomy in Italy, two Florentines recorded observations of the sun and moon, comets, and meteorology. Paolo dal Pozzi Toscanelli flourished in the first half of the 15th century and Leonardo da Vinci in the last half. Their observations of celestial phenomena were not primarily for astronomical purposes; they were spinoffs of other pursuits such as medicine, astrology, optics, engineering, and studies of light and shadow. As a physician and cartographer, Toscanelli practiced astrology, studied omens, observed comets and plotted their paths on homemade maps. He also was associated with the construction of a gnomon at the top of the Duomo to observe the summer solstice. It was this project that may have brought him into contact with the young artisan, Leonardo da Vinci. As a painter, Leonardo's approach to science and engineering was to observe, sketch and analyze. His interest in light and shadow led him to notice how the earth, moon and planets all reflect sunlight. His extant manuscripts have geometric sketches for eclipses and for the phenomenon known as "old moon in new moon's arms." Unfortunately, because neither Toscanelli nor Leonardo published their observations, they made no impact on the history of astronomical thought or observation. Their contemporaries did not know or write about their work. Astronomers in the 16th century did not know about

  10. The Real Code of Leonardo da Vinci

    PubMed Central

    Ose, Leiv

    2008-01-01

    Leonardo da Vinci was born in Italy. Among the researchers and scientists, he is favourably known for his remarkable efforts in scientific work. His investigations of atherosclerosis judiciously combine three separate fields of research. In 1506, he finished his masterpiece, painting of Mona Lisa. A careful clinical examination of the famous painting reveals a yellow irregular leather-like spot at the inner end of the left upper eyelid and a soft bumpy well-defined swelling of the dorsum of the right hand beneath the index finger about 3 cm long. This is probably the first case of familial hypercholesterolemia (FH). The FH code of Leonardo da Vinci was given immense consideration by scientists like Carl Muller, who described the xanthomas tuberosum and angina pectoris. On the contrary, Akira Endo searched for microbial metabolites that would inhibit HMG-CoA reductase, the rate-limiting enzyme in the synthesis of cholesterol and finally, Michael Brown and Joseph Goldstein published a remarkable series of elegant and insightful papers in the 70s and 80s. They established that the cellular uptake of low-density lipoprotein (LDL) essentially requires the LDL receptor. In conclusion: this was the real Code of Leonardo da Vinci. PMID:19924278

  11. In search of Leonardo: computer-based facial image analysis of Renaissance artworks for identifying Leonardo as subject

    Tyler, Christopher W.; Smith, William A. P.; Stork, David G.

    2012-03-01

    One of the enduring mysteries in the history of the Renaissance is the adult appearance of the archetypical "Renaissance Man," Leonardo da Vinci. His only acknowledged self-portrait is from an advanced age, and various candidate images of younger men are difficult to assess given the absence of documentary evidence. One clue about Leonardo's appearance comes from the remark of the contemporary historian, Vasari, that the sculpture of David by Leonardo's master, Andrea del Verrocchio, was based on the appearance of Leonardo when he was an apprentice. Taking a cue from this statement, we suggest that the more mature sculpture of St. Thomas, also by Verrocchio, might also have been a portrait of Leonardo. We tested the possibility Leonardo was the subject for Verrocchio's sculpture by a novel computational technique for the comparison of three-dimensional facial configurations. Based on quantitative measures of similarities, we also assess whether another pair of candidate two-dimensional images are plausibly attributable as being portraits of Leonardo as a young adult. Our results are consistent with the claim Leonardo is indeed the subject in these works, but we need comparisons with images in a larger corpora of candidate artworks before our results achieve statistical significance.

  13. Leonardo Da Vinci, the genius and the monsters. Casual encounters?

    PubMed

    Ciseri, Lorenzo Montemagno

    2014-01-01

    This article analyses Leonardo's interest in monsters and deformed reality, one of the lesser known aspects of his vast and multifaceted output. With the possible exception of his studies of physiognomy, relevant drawings, sketches and short stories represent a marginal aspect of his work, but they are nevertheless significant for historians of teratology. The purpose of this study is to provide a broad overview of the relationship between Leonardo and both the literature on mythological monsters and the reports on monstrous births that he either read about or witnessed personally. While aspects of his appreciation and attention to beauty and the pursuit of perfection and good proportions are the elements most emphasised in Leonardo's work, other no less interesting aspects related to deformity have been considered of marginal importance. My analysis will demonstrate that Leonardo approached the realm of monstrosity as if he considered abnormality a mirror of normality, deformity a mirror of harmony, and disease a mirror of health, as if to emphasise that, ultimately, it is the monster that gives the world the gift of normality. Two special cases of monstrosity are analysed: the famous monster of Ravenna, whose image was found among his papers, and a very rare case of parasitic conjoined twins (thoracopagus parasiticus) portrayed for the first time alive, probably in Florence, by Leonardo himself.

  14. [Regarding the Manuscript D " Dell' occhio " of Leonardo da Vinci].

    PubMed

    Heitz, Robert F

    2009-01-01

    Leonardo da Vinci's Manuscript D consists of five double pages sheets, which, folded in two, comprise ten folios. This document, in the old Tuscan dialect and mirror writing, reveals the ideas of Leonardo on the anatomy of the eye in relation to the formation of images and visual perception. Leonardo explains in particular the behavior of the rays in the eye in terms of refraction and reflection, and is very mechanistic in his conception of the eye and of the visual process. The most significant innovations found in these folios are the concept of the eye as a camera obscura and the intersection of light rays in the interior of the eye. His texts nevertheless show hesitation, doubts and a troubled confusion, reflecting the ideas and uncertainties of his era. He did not share his results in his lifetime, despite both printing and etching being readily available to him. PMID:19852385

  15. Leonardo da Vinci and the origin of semen

    PubMed Central

    Noble, Denis; DiFrancesco, Dario; Zancani, Diego

    2014-01-01

    It is well known that Leonardo da Vinci made several drawings of the human male anatomy. The early drawings (before 1500) were incorrect in identifying the origin of semen, where he followed accepted teaching of his time. It is widely thought that he did not correct this mistake, a view that is reflected in several biographies. In fact, he made a later drawing (after 1500) in which the description of the anatomy is remarkably accurate and must have been based on careful dissection. In addition to highlighting this fact, acknowledged previously in only one other source, this article reviews the background to Leonardo's knowledge of the relevant anatomy. PMID:27494016

  4. How did Leonardo perceive himself? Metric iconography of da Vinci's self-portraits

    NASA Astrophysics Data System (ADS)

    Tyler, Christopher W.

    2010-02-01

    Some eighteen portraits are now recognized of Leonardo in old age, consolidating the impression from his bestestablished self-portrait of an old man with long white hair and beard. However, his appearance when younger is generally regarded as unknown, although he was described as very beautiful as a youth. Application of the principles of metric iconography, the study of the quantitative analysis of the painted images, provides an avenue for the identification of other portraits that may be proposed as valid portraits of Leonardo during various stages of his life, by himself and by his contemporaries. Overall, this approach identifies portraits of Leonardo by Verrocchio, Raphael, Botticelli, and others. Beyond this physiognomic analysis, Leonardo's first known drawing provides further insight into his core motivations. Topographic considerations make clear that the drawing is of the hills behind Vinci with a view overlooking the rocky promontory of the town and the plain stretching out before it. The outcroppings in the foreground bear a striking resemblance to those of his unique composition, 'The Virgin of the Rocks', suggesting a deep childhood appreciation of this wild terrain. and an identification with that religious man of the mountains, John the Baptist, who was also the topic of Leonardo's last known painting. Following this trail leads to a line of possible selfportraits continuing the age-regression concept back to a self view at about two years of age.

  5. Tree Branching: Leonardo da Vinci's Rule versus Biomechanical Models

    PubMed Central

    Minamino, Ryoko; Tateno, Masaki

    2014-01-01

    This study examined Leonardo da Vinci's rule (i.e., the sum of the cross-sectional area of all tree branches above a branching point at any height is equal to the cross-sectional area of the trunk or the branch immediately below the branching point) using simulations based on two biomechanical models: the uniform stress and elastic similarity models. Model calculations of the daughter/mother ratio (i.e., the ratio of the total cross-sectional area of the daughter branches to the cross-sectional area of the mother branch at the branching point) showed that both biomechanical models agreed with da Vinci's rule when the branching angles of daughter branches and the weights of lateral daughter branches were small; however, the models deviated from da Vinci's rule as the weights and/or the branching angles of lateral daughter branches increased. The calculated values of the two models were largely similar but differed in some ways. Field measurements of Fagus crenata and Abies homolepis also fit this trend, wherein models deviated from da Vinci's rule with increasing relative weights of lateral daughter branches. However, this deviation was small for a branching pattern in nature, where empirical measurements were taken under realistic measurement conditions; thus, da Vinci's rule did not critically contradict the biomechanical models in the case of real branching patterns, though the model calculations described the contradiction between da Vinci's rule and the biomechanical models. The field data for Fagus crenata fit the uniform stress model best, indicating that stress uniformity is the key constraint of branch morphology in Fagus crenata rather than elastic similarity or da Vinci's rule. On the other hand, mechanical constraints are not necessarily significant in the morphology of Abies homolepis branches, depending on the number of daughter branches. Rather, these branches were often in agreement with da Vinci's rule. PMID:24714065

    Examining botanical trees, Leonardo da Vinci noted that the total cross section of branches is conserved across branching nodes. In this Letter, it is proposed that this rule is a consequence of the tree skeleton having a self-similar structure and the branch diameters being adjusted to resist wind-induced loads.

    2014-06-01

    The discoloration of ancient paper, due to the development of oxidized groups acting as chromophores in its chief component, cellulose, is responsible for severe visual degradation in ancient artifacts. By adopting a non-destructive approach based on the combination of optical reflectance measurements and time-dependent density functional theory ab-initio calculations, we describe and quantify the chromophores affecting Leonardo da Vinci's iconic self-portrait. Their relative concentrations are very similar to those measured in modern and ancient samples aged in humid environments. This analysis quantifies the present level of optical degradation of the Leonardo da Vinci's self-portrait which, compared with future measurements, will assess its degradation rate. This is a fundamental information in order to plan appropriate conservation strategies.

  14. Leonardo da Vinci and Andreas Vesalius; the shoulder girdle and the spine, a comparison.

    PubMed

    Ganseman, Y; Broos, P

    2008-01-01

    Leonardo Da Vinci and Andreas Vesalius were two important renaissance persons; Vesalius was a surgeon-anatomist who delivered innovative work on the study of the human body, Leonardo da Vinci was an artist who delivered strikingly accurate and beautiful drawings on the human body. Below we compare both masters with regard to their knowledge of the working of the muscles, their method and system of dissection and their system and presentation of the drawings. The investigation consisted of a comparison between both anatomists, in particular concerning their study on the shoulder girdle and spine, by reviewing their original work as well as already existing literature on this subject. The investigation led to the conclusion that the drawings mentioned meant a change in history, and were of high quality, centuries ahead of their time. Both were anatomists, both were revolutionary, only one changed history at the moment itself, while the other changed history centuries later. Leonardo has made beautiful drawings that are at a match with the drawings of today or are even better. Vesalius set the start for medicine as a science as it is until this day. Their lives differed as strongly as their impact. In the light of their time, the achievement they made was extraordinary. PMID:18807610

    PubMed

    Le Floch-Prigent, P

    2008-12-01

    The aim of the study was to find out and to analyse the text by Vitruvius which inspired the famous drawing by Leonardo da Vinci (circa 1490) kept in the Galleria dell'Accademia, in Venezia, Italy: the man inscribed in one circle and in one square. The book "de Architectura" by Vitruvius Marcus Pollio was printed several times since the Renaissance when both the roman architecture of antiquity and this text became very popular. From a French translation by Claude Perrault in 1864, it became easy to find a French translation with the original text in Latin (Paris, 2003, Les Belles Lettres, French text by Pierre Gros). The drawing by Leonardo da Vinci illustrates with great accuracy and fidelity the quotation of Vitruvius (with the exception of two of the 12 main relationships). The genius of Leonardo da Vinci was to keep only one trunk, head and neck for two pairs of limbs: scapular and pelvic; to make the circle tangent to the lower edge of the square; to adjust a few features of the quotation for the equilibrium of the whole figure; and of course to bring his incredible skill as a drawer (one of the best of his century). The drawing was made on a sheet of paper 344x245mm, in black ink which became dark brown with time; several lines complete the figure above and below; a short caption and a horizontal scale appear just under the drawing. The celebrity of the drawing, a symbol of the Renaissance, of the equilibrium of man and mankind, of the universality of the artists and intellectuals of the time (Humanism) made it iconic and it has been constantly reproduced and adapted especially for advertisement and logos, not only in the medical field.

    2011-11-01

    In his notebooks, Leonardo da Vinci observed that ``all the branches of a tree at every stage of its height when put together are equal in thickness to the trunk,'' which means that the total cross-sectional area of branches is conserved across branching nodes. The usual explanation for this rule involves vascular transport of sap, but this argument is questionable because the portion of wood devoted to transport varies across species and can be as low as 5%. It is proposed here that Leonardo's rule is a consequence of the tree skeleton having a self-similar structure and the branch diameters being adjusted to resist wind-induced loads. To address this problem, a continuous model is first considered by neglecting the geometrical details of branching and wind incident angles. The robustness of this analytical model is then assessed with numerical simulations on tree skeletons generated with a simple branching rule producing self-similar structures. This study was supported by the European Union through the fellowship PIOF-GA-2009-252542.

    Leonardo-BRDF is a NASA mission concept proposed to allow the investigation of radiative transfer and its effect on the Earth's climate and atmospheric phenomenon. Enabled by the recent developments in small-satellite and formation flying technology, the mission is envisioned to be composed of an array of spacecraft in carefully designed orbits. The different perspectives provided by a distributed array of spacecraft offer a unique advantage to study the Earth's albedo. This paper presents the orbit dynamics analysis performed in the context of the Leonardo-BRDF science requirements. First, the albedo integral is investigated and the effect of viewing geometry on science return is studied. The method used in this paper, based on Gauss quadrature, provides the optimal formation geometry to ensure that the value of the integral is accurately approximated. An orbit design approach is presented to achieve specific relative orbit geometries while simultaneously satisfying orbit dynamics constraints to reduce formation-keeping fuel expenditure. The relative geometry afforded by the design is discussed in terms of mission requirements. An optimal two-burn initialization scheme is presented with the required delta-V to distribute all spacecraft from a common parking orbit into their appropriate orbits in the formation. Finally, formation-keeping strategies are developed and the associated delta-V's are calculated to maintain the formation in the presence of perturbations.

  19. The uncatchable smile in Leonardo da Vinci's La Bella Principessa portrait.

    A portrait of uncertain origin recently came to light which, after extensive research and examination, was shown to be that rarest of things: a newly discovered Leonardo da Vinci painting entitled La Bella Principessa. This research presents a new illusion which is similar to that identified in the Mona Lisa; La Bella Principessa's mouth appears to change slant depending on both the Viewing Distance and the Level of Blur applied to a digital version of the portrait. Through a series of psychophysics experiments, it was found that a perceived change in the slant of the La Bella Principessa's mouth influences her expression of contentment thus generating an illusion that we have coined the "uncatchable smile". The elusive quality of the Mona Lisa's smile has been previously reported (Science, 290 (2000) 1299) and so the existence of a similar illusion in a portrait painted prior to the Mona Lisa becomes more interesting. The question remains whether Leonardo da Vinci intended this illusion. In any case, it can be argued that the ambiguity created adds to the portrait's allure. PMID:26049039

    The author discusses a previously unknown early sixteenth-century renaissance handmade anatomical miniature skull. The small, naturalistic skull made from an agate (calcedonia) stone mixture (mistioni) shows remarkable osteologic details. Dr. Saban was the first to link the skull to Leonardo. The three-dimensional perspective of and the search for the senso comune are discussed. Anatomical errors both in the drawings of Leonardo and this skull are presented. The article ends with the issue of physiognomy, his grotesque faces, the Perspective Communis and his experimenting c. 1508 with the stone mixture and the human skull. Evidence, including the Italian scale based on Crazie and Braccia, chemical analysis leading to a mine in Volterra and Leonardo's search for the soul in the skull are presented. Written references in the inventory of Salai (1524), the inventory of the Villa Riposo (Raffaello Borghini 1584) and Don Ambrogio Mazenta (1635) are reviewed. The author attributes the skull c. 1508 to Leonardo da Vinci. PMID:24853982

    Following the discovery of discoloration on some pages of the Atlantic Codex (AC) of Leonardo da Vinci kept in the Biblioteca Ambrosiana in Milan, some investigations have been carried out to verify the presence of microorganisms, such as bacteria and fungi. To verify the presence of microorganisms a noninvasive method of sampling has been used that was efficient and allowed us to highlight the microbial facies of the material that was examined using conventional microbiological techniques. The microclimatic conditions in the storage room as well as the water content of the volume were also assessed. The combined observations allowed the conclusion that the discoloration of suspected biological origin on some pages of AC is not related to the presence or current attack of microbial agents.

    Physics textbooks often present items of disciplinary knowledge in a sequential order of topics of the theory under instruction. Such presentation is usually univocal, that is, isolated from alternative claims and contributions regarding the subject matter in the pertinent scientific discourse. We argue that comparing and contrasting the contributions of scientists addressing similar or the same subject could not only enrich the picture of scientific enterprise, but also possess a special appealing power promoting genuine understanding of the concept considered. This approach draws on the historical tradition from Plutarch in distant past and Koyré in the recent history and philosophy of science. It gains a new support in the discipline-culture structuring of the physics curriculum, seeking cultural content knowledge (CCK) of the subject matter. Here, we address two prominent individuals of Italian Renaissance, Leonardo and Galileo, in their dealing with issues relevant for introductory science courses. Although both figures addressed similar subjects of scientific content, their products were essentially different. Considering this difference is educationally valuable, illustrating the meaning of what students presently learn in the content knowledge of mechanics, optics and astronomy, as well as the nature of science and scientific knowledge.

    Surgery in the Middle Ages was practiced by individuals belonging to the guild of barbers, with no basic medical education. The transformation into a scientific branch of medicine began in the sixteenth century. In this process, a great role was the one played by Leonardo Fioravanti. He was a Doctor in Medicine graduated from the University of Bologna. A controversial man, he was also an innovation in many fields of medicine, such as prevention of diseases, pharmacology, therapy, etc., and he was a surgeon himself. On the way back from one of the last Crusades, he visited the Vianeos brothers in Calabria, and he was able to learn from them the technique for reconstructing the nose that had been devised by Antonio Branca in the previous century and still practiced only by barber-surgeons. He published his experience in a book that probably inspired the contemporary, Gaspare Tagliacozzi, Professor at the University of Bologna, and allowed him to become acquainted with this kind of reconstructive surgery. Tagliacozzi understood the value of the method described by Fioravanti and transformed a barber-surgery technique into a remarkable chapter of scientific surgery by divulging in the academic circles the principles of the pedicled flap, which have been the basis for development of modern plastic surgery.

    E-learning will play an important role in the training portfolio of students in higher and vocational education. Within the LEONARDO-DA-VINCI action programme transnational pilot projects were funded by the European Union, which aimed to improve the usage and quality of e-learning tools in education and professional training. The overall aim of the LEONARDO-DA-VINCI pilot project "e-learning-assistant" was to create new didactical and technical e-learning tools for Europe-wide use in nursing education. Based on a new situation-oriented learning approach, nursing teachers enrolled in the project were instructed to adapt, develop and implement e- and blended learning units. According to the training contents nursing modules were developed by teachers from partner institutions, implemented in the project centers and evaluated by students. The user-package "e-learning-assistant" as a product of the project includes two teacher training units, the authoring tool "synapse" to create situation-based e-learning units, a student's learning platform containing blended learning modules in nursing and an open sourced web-based communication centre.

    2008-12-01

    In four earlier articles, I focused on the theme of the relationship of melancholia and the mother, and suggested that the melancholic self may experience humor (Capps, 2007a), play (Capps, 2007b), dreams (Capps, 2008a), and art (Capps, 2008b) as restorative resources. I argued that Erik H. Erikson found these resources to be valuable remedies for his own melancholic condition, which had its origins in the fact that he was illegitimate and was raised solely by his mother until he was three years old, when she remarried. In this article, I focus on two themes in Freud's Leonardo da Vinci and a memory of his childhood (1964): Leonardo's relationship with his mother in early childhood and his inhibitions as an artist. I relate these two themes to Erikson's own early childhood and his failure to achieve his goal as an aspiring artist in his early twenties. The article concludes with a discussion of Erikson's frustrated aspirations to become an artist and his emphasis, in his psychoanalytic work, on children's play. PMID:19093682

    The strategies that experts have used to share information about social causes have historically been top-down, meaning the most influential messages are believed to come from planned events and campaigns. However, more people are independently engaging with social causes today than ever before, in part because online platforms allow them to instantaneously seek, create, and share information. In some cases this “organic advocacy” may rival or even eclipse top-down strategies. Big data analytics make it possible to rapidly detect public engagement with social causes by analyzing the same platforms from which organic advocacy spreads. To demonstrate this claim we evaluated how Leonardo DiCaprio’s 2016 Oscar acceptance speech citing climate change motivated global English language news (Bloomberg Terminal news archives), social media (Twitter postings) and information seeking (Google searches) about climate change. Despite an insignificant increase in traditional news coverage (54%; 95%CI: -144 to 247), tweets including the terms “climate change” or “global warming” reached record highs, increasing 636% (95%CI: 573–699) with more than 250,000 tweets the day DiCaprio spoke. In practical terms the “DiCaprio effect” surpassed the daily average effect of the 2015 Conference of the Parties (COP) and the Earth Day effect by a factor of 3.2 and 5.3, respectively.

    This work focuses on the composition and microstructure of the lead white pigment employed in a set of paintworks, using a combination of µ-XRD and 2D scanning XRF, directly applied on five drapery studies attributed to Leonardo da Vinci (1452-1519) and conserved in the Département des Arts Graphiques, Musée du Louvre and in the Musée des Beaux- Arts de Rennes. Trace elements present in the composition as well as in the lead white highlights were imaged by 2D scanning XRF. Mineral phases were determined in a fully noninvasive way using a special µ-XRD diffractometer. Phase proportions were estimated by Rietveld refinement. The analytical results obtained will contribute to differentiate lead white qualities and to highlight the artist's technique.

  13. A psychoanalytic understanding of the desire for knowledge as reflected in Freud's Leonardo da Vinci and a memory of his childhood.

    2006-10-01

    The author offers an understanding of the psychoanalytic notion of the desire for knowledge and the possibility of attaining it as it fi nds expression in Freud's Leonardo da Vinci and a memory of his childhood. This understanding has not been explicitly articulated by Freud but may be considered integral to psychoanalysis' Weltanschauung as shaped by Freud's legacy. It emerges through an attempt to explain basic shifts, contradictions, inconsistencies and tensions that become apparent from a close reading of the text of Leonardo. Articulating this implicit understanding of knowledge provides the grounds for a stance on epistemology that is integral to psychoanalysis and relevant to contemporary psychoanalytic concerns on this topic. This epistemology focuses on the necessary involvement of passion, rather than detachment, in the search for knowledge and views the psychoanalytic aim of self-knowledge as a derivative, and most immediate expression, of a broader and more basic human drive to know.

    3D measurement and modelling have been traditionally applied to statues, buildings, archeological sites or similar large structures, but rarely to paintings. Recently, however, 3D measurements have been performed successfully also on easel paintings, allowing to detect and document the painting's surface. We used 3D models to integrate the results of various 2D imaging techniques on a common reference frame. These applications show how the 3D shape information, complemented with 2D colour maps as well as with other types of sensory data, provide the most interesting information. The 3D data acquisition was carried out by means of two devices: a high-resolution laser micro-profilometer, composed of a commercial distance meter mounted on a scanning device, and a laser-line scanner. The 2D data acquisitions were carried out using a scanning device for simultaneous RGB colour imaging and IR reflectography, and a UV fluorescence multispectral image acquisition system. We present here the results of the techniques described, applied to the analysis of an important painting of the Italian Reinassance: `Madonna dei Fusi', attributed to Leonardo da Vinci.

    Summary Leonardo da Vinci's self‐portrait is affected by foxing spots. The portrait has no fungal or bacterial infections in place, but is contaminated with airborne spores and fungal material that could play a role in its disfigurement. The knowledge of the nature of the stains is of great concern because future conservation treatments should be derived from scientific investigations. The lack of reliable scientific data, due to the non‐culturability of the microorganisms inhabiting the portrait, prompted the investigation of the drawing using non‐invasive and micro‐invasive sampling, in combination with scanning electron microscope (SEM) imaging and molecular techniques. The fungus E urotium halophilicum was found in foxing spots using SEM analyses. Oxalates of fungal origin were also documented. Both findings are consistent with the hypothesis that tonophilic fungi germinate on paper metabolizing organic acids, oligosaccharides and proteic compounds, which react chemically with the material at a low water activity, forming brown products and oxidative reactions resulting in foxing spots. Additionally, molecular techniques enabled a screening of the fungi inhabiting the portrait and showed differences when different sampling techniques were employed. Swabs samples showed a high abundance of lichenized Ascomycota, while the membrane filters showed a dominance of A cremonium sp. colonizing the drawing. PMID:26111623

Their comparison with the Latin texts available before 1500 shows that they derive from the De speculis comburentibus of Alhacen and the De speculis comburentibus of Regiomontanus, joined together in his autograph manuscript (Vienna, Oster. Nationalbibliothek, Cod. 5258). Having identified the sources, and discussed their mathematics, the issue of their transmission is targeted. It is shown that these notes were written by Paolo dal Pozzo Toscanelli, through whom they reached the notebooks of Leonardo da Vinci. PMID:26104302

    The interpretation of the heart as a mechanical engine dates back to the teachings of Leonardo da Vinci, who was the first to apply the laws of mechanics to the function of the heart. Similar to any mechanical engine, whose performance is proportional to the power generated with respect to weight, the left ventricle can be viewed as a power generator whose performance can be related to left ventricular mass. Stress echocardiography may provide valuable information on the relationship between cardiac performance and recruited left ventricular mass that may be used in distinguishing between adaptive and maladaptive left ventricular remodeling. Peak power output-to-mass, obtained during exercise or pharmacological stress echocardiography, is a measure that reflects the number of watts that are developed by 100 g of left ventricular mass under maximal stimulation. Power output-to-mass may be calculated as left ventricular power output per 100 g of left ventricular mass: 100× left ventricular power output divided by left ventricular mass (W/100 g). A simplified formula to calculate power output-to-mass is as follows: 0.222 × cardiac output (l/min) × mean blood pressure (mmHg)/left ventricular mass (g). When the integrity of myocardial structure is compromised, a mismatch becomes apparent between maximal cardiac power output and left ventricular mass; when this occurs, a reduction of the peak power output-to-mass index is observed.

    1994-02-01

    In view of the fact that as a child Sigmund Freud was looked after by two mothers--his actual mother and a nursemaid--it is hardly surprising that traces of this pre-oedipal situation, fraught as it was with traumatisation and loss, should be discernible in the works of the creator of psychoanalysis. Freud's continued preoccupation with the Oedipus myth, his interest in "great men" like da Vinci and Michelangelo, and finally his identification with the figure of Moses are pointers not only to the paternal dimension (as long suggested by Freud's biographers) but also to the maternal dimension and its significance for Freud's life and work. The author demonstrates that those mythical and historical figures which Freud identified with--Oedipus, da Vinci, Michelangelo, Moses--themselves all had two mothers and sublimated this traumatic experience into outstanding achievements, the same being true of Freud himself "who solved the famous riddle and was a most powerful man".

Inventor of the first antiplague costume is considered to be a French doctor Charles de Lorme (1619). Much later, in 1878, a Russian professor Pashutin V V offered to use a costume, which looked like a hermetically sealed "bag" with a special breathing device aimed at protection of medical staff. Later, professor O.I. Dogel's respirator became well-known (1889). At the beginning of 20th century as part of the antiplague costume was used a charcoal filter mask, invented by Zelinsky N.D. Requirements to order the use of modern means of individual protection when working in nidus of especially dangerous infections identified sanitary-epidemiological rules, which reflect issues of laboratory workers working and protective clothing, respiratory protection, and view, especially operation, the procedure of putting on, removing and disinfecting antiplague costumes, pneumocostumes, pneumohelmets, isolation suits, gas-protection boxes, etc. PMID:27120957

  3. Da Vinci's codex and the anatomy of healthcare.

    PubMed

    Stephens-Borg, Keith

    2012-08-01

    We usually display a laid-back approach to medical jargon throughout our theatre work. The word 'perioperative' is built from the Greek word 'peri' (around) and the Latin 'operari' (to work). Latin and Greek became the prefixed language of choice for Leonardo da Vinci, and his research was pivotal in determining the way in which surgical procedures are documented. Ancient manuscripts aided the unfolding of the secrets of anatomy, and Leonardo revealed that art was the key in expressive detailed explanation. PMID:23248927

  4. Differential PIXE for investigating the layer structure of paintings

    NASA Astrophysics Data System (ADS)

    Mandò, P. A.; Fedi, M. E.; Grassi, N.; Migliori, A.

    2005-09-01

    This paper reports an example of how the differential PIXE technique can be successfully applied to the investigation of wood or canvas paintings. The work analysed is a famous wood painting by Leonardo da Vinci, the "Madonna dei fusi" (ex-Reford version, 1501), chosen for a pilot study in a wide international project aimed at analysing Leonardo's works of art by means of non-destructive techniques. While illustrating the results obtained concerning the identification of pigments and the discrimination of the stratigraphy of layers, the merits and limits of differential PIXE in general are pointed out.

  5. Bubbles

    NASA Astrophysics Data System (ADS)

    Prosperetti, Andrea

    2004-06-01

    Vanitas vanitatum et omnia vanitas: bubbles are emptiness, non-liquid, a tiny cloud shielding a mathematical singularity. Born from chance, a violent and brief life ending in the union with the (nearly) infinite. But a wealth of phenomena spring forth from this nothingness: underwater noise, sonoluminescence, boiling, and many others. Some recent results on a "blinking bubble" micropump and vapor bubbles in sound fields are outlined. The last section describes Leonardo da Vinci's observation of the non-rectlinear ascent of buoyant bubbles and justifies the name Leonardo's paradox recently attributed to this phenomenon.

  20. [The "myologie dynamique" by Girolamo Fabrizi da Aquapendente in the scientific language in the Renaissance age (XVI-XVII)].

    PubMed

    Stroppiana, L

    1989-01-01

    Beginning from the XV century, mechanical materialism underwent an evolution in "biological mechanics" within the scientific doctrine. Among the greatest exponents of this new current there were two Italian men, Leonardo da Vinci (1452-1519) and Girolamo da Acquapendente (1533-1619). By the trend given by Leonardo, the myology, instead of being a static science, took a dynamic meaning and valence. Later, Fabrizi resumed and investigated the subject above all in its less known expression, elaborating an original theory. With Acquapendente, the anatomy lost its merely descriptive pecularity and evolved in analysis of the structure in connection with the function. Moreover, he opposed the syllogism against the mechanic language and the mathematical formulation. A new scientific way will be afterwards characterized by Galileo Galilei in the field of the physics and by Giovanni Alfonso Borrelli in the biology. PMID:11640090

    Previously, anatomists considered paranasal sinuses as a mysterious region of the human skull. Historically, paranasal sinuses were first identified by ancient Egyptians and later, by Greek physicians. After a long period of no remarkable improvement in the understanding of anatomy during the Middle Ages, anatomists of the Renaissance period-Leonardo da Vinci and Vesalius-made their own contribution. Nathaniel Highmore's name is also associated with the anatomy of paranasal sinuses as he was first to describe the maxillary sinus. PMID:24386595

    Leonardo da Vinci clearly observed and described capillaries. Using the microscope, Marcello Malpighi examined the brain and major organs to demonstrate their finer anatomical features. This led to his discovery in 1661, of capillaries that proved fundamental to our understanding of the vascular system in the brain and cord. He hypothesized that capillaries were the connection between arteries and veins that allowed blood to flow back to the heart in the circulation of the blood, as first asserted by William Harvey.

  9. Computer Studies Of The Isleworth And Louvre Mona Lisas

    NASA Astrophysics Data System (ADS)

    Asmus, John F.

    1989-07-01

    One of the most pervasive problems in the scholarship of classical paintings is that of authenticity. Traditionally, the attribution of a work of art rests on the subjective opinion of an art historian bolstered by scientific data pertaining to the types and possibly the ages of the materials of the artwork. To expand the range of technical information that may be applied to the painting authentication problem, the methods of computer image processing (IP) have been employed to compare the techniques in two paintings. One is the Mona Lisa del Gioconda by Leonardo da Vinci. The other is known as the Isleworth Mona Lisa and has also been attributed to Leonardo by a few scholars. Computer IP was used to compare statistical and geometrical features of the two paintings. It emerged that the Isleworth work is not a copy of the Louvre painting but does have numerous similarities in composition and execution. These findings lend support to the theory that the Louvre Mona Lisa may be a portrait of Costanza by Leonardo that had been thought lost.

    It is rare that the analyses of materials in paintings can be carried out by taking micro-samples. Valuable works of art are best studied in situ by non-invasive techniques. For that purpose, a portable X-ray diffraction and fluorescence apparatus has been designed and constructed at the C2RMF. This apparatus has been used for paintings of Rembrandt, Leonardo da Vinci, Van Gogh, Mantegna, etc. Results are given to illustrate the performance of X-ray diffraction, especially when X-ray fluorescence does not bring sufficient information to conclude.

    We see with our mind's eye. This poetic phrase attempts to describe a complex set of human interactions by which we take in and process information about the physical world around us. For millennia, scientists and philosophers have relied on our ability to apply the uniquely human traits of perception, cognition, memory and motor action to scientific observations and experiments. "There is no authority higher than the human eye," observed Leonardo Da Vinci, and his statement still holds true; as most field scientists will attest, there is no substitute for direct observation.

    Summary This lecture is not a historical lecture, but rather a journey through the “story” of neurology in Italy from its “prehistoric” beginning in the 19th century. The birth of a neurological school is that magical moment in which a founder attracts disciples: the more capable this founder is of transmitting methodology and allowing his pupils intellectual freedom, the longer his memory will live on. On the basis of this idea, the scientific biography of a few leading Italian neurologists of the 20th century is outlined, starting from Leonardo Bianchi, founder of the Italian Neurological Society in 1907.

    In Italy, biomechanics research and the analysis of human and animal movement have had a very long history, beginning with the exceptional pioneering work of Leonardo da Vinci. In 1489, da Vinci began investigating human anatomy, including an examination of human tendons, muscles, and the skeletal system. He continued this line of inquiry later in life, identifying what he called "the four powers--movement, weight, force, and percussion"--and how he thought they worked in the human body. His approach, by the way, was very modern--analyzing nature through anatomy, developing models for interpretation, and transferring this knowledge to bio-inspired machines. PMID:26186054

    2010-01-01

    The Multi-Purpose Logistics Module (MPLM) are pressurized modules for transporting equipment, supplies and experimental devices to and from the International Space Station (ISS). An MPLM is carried in the cargo bay of a Shuttle and attached to the Unity or Harmony modules on the ISS for the duration of a mission, usually about 10 days. From there, supplies are offloaded, and finished experiments and waste are reloaded. The MPLM is then returned to the Space Shuttle payload bay for return to Earth. Three modules were built, Leonardo, Raffaello and Donatello. The modules were provided to NASA under contract by the Italian Space Agency. Each MPLM was built to be on-orbit a maximum of one month at a time. The MPLM Leonardo is being modified to turn it into the Pressurized Multipurpose Module (PMM), which will remain permanently attached to the ISS following the STS- 133 mission. The Space Shuttle is the only vehicle or rocket that has the capacity to carry the MPLM to the ISS. With the planned retirement of the Space Shuttle in 2011, NASA has found another use for the MPLM. With the modifications of the MPLM into a PMM the ISS will have another permanent module as part of the ISS that will be used as a storage module

    STS-102 mission astronaut Susan J. Helms translates along the longerons of the Space Shuttle Discovery during the first of two space walks. During this walk, the Pressurized Mating Adapter 3 was prepared for repositioning from the Unity Module's Earth-facing berth to its port-side berth to make room for the Leonardo multipurpose Logistics Module (MPLM), supplied by the Italian Space Agency. The Leonardo MPLM is the first of three such pressurized modules that will serve as the International Space Station's (ISS') moving vans, carrying laboratory racks filled with equipment, experiments, and supplies to and from the Station aboard the Space Shuttle. The cylindrical module is approximately 21-feet long and 15- feet in diameter, weighing almost 4.5 tons. It can carry up to 10 tons of cargo in 16 standard Space Station equipment racks. Of the 16 racks the module can carry, 5 can be furnished with power, data, and fluid to support refrigerators or freezers. In order to function as an attached station module as well as a cargo transport, the logistics module also includes components that provide life support, fire detection and suppression, electrical distribution, and computer functions. NASA's 103rd overall mission and the 8th Space Station Assembly Flight, STS-102 mission also served as a crew rotation flight. It delivered the Expedition Two crew to the Station and returned the Expedition One crew back to Earth.

  2. Andrea del Sarto rehabilitated: a psychoanalytic emendation.

    PubMed

    Trosman, Harry

    2002-01-01

    Ernest Jones's "The Influence of Andrea del Sarto's Wife on His Art" (1913) is an early example of psychoanalysis applied to the study of a prominent painter. Greatly influenced by Freud's Leonardo da Vinci and a Memory of His Childhood, Jones gave excessive credence to Vasari's highly prejudicial account of the life of del Sarto, on which the study relied heavily. Jones attempted to account psychologically for the circumstance that del Sarto, though highly skilled and "faultless," was not the equal of the three preeminent masters of the Italian High Renaissance: Leonardo, Michelangelo, and Raphael. Jones's uncritical acceptance of the Vasari biography encouraged him to view Sarto's assumed deficiency as the result of excessive attachment to his wife, a pathological uxoriousness. A contemporary psychoanalytic perspective, with its emphasis on the emotive response of the analyst, requires us to pay attention to the evocative nature of the work of the artist, an approach Jones neglected. In an examination of several paintings, the artist's sensitivity to the position of the spectator is explored, as is the interest in involving the viewer spatially and emotionally. An appreciation for the viewer's position is consistent with a capacity for using projected internal objects for creative purposes. The presence of this capacity suggests a revised view of del Sarto's contribution to art and of his relationship with his wife. PMID:12580329

    Kervella, Pierre; Coudé du Foresto, Vincent; Glindemann, Andreas; Hofmann, Reiner

    2000-07-01

    The Very Large Telescope Interferometer (VLTI) is a complex system, made of a large number of separated elements. To prepare an early successful operation, it will require a period of extensive testing and verification to ensure that the many devices involved work properly together, and can produce meaningful data. This paper describes the concept chosen for the VLTI commissioning instrument, LEONARDO da VINCI, and details its functionalities. It is a fiber based two-way beam combiner, associated with an artificial star and an alignment verification unit. The technical commissioning of the VLTI is foreseen as a stepwise process: fringes will first be obtained with the commissioning instrument in an autonomous mode (no other parts of the VLTI involved); then the VLTI telescopes and optical trains will be tested in autocollimation; finally fringes will be observed on the sky.

  6. Science versus (?) Art: Human Perception of Other Worlds

    NASA Astrophysics Data System (ADS)

    Hartmann, William K.

    1998-09-01

    At the time of the Renaissance, science and art were mixed together as a way to understand the human relation to the larger cosmos. Leonardo da Vinci exemplifies this approach. In modern times, the two have become separate, and even antagonistic, ``two cultures." Scientists have increasingly been satisfied to present quantitative measures of phenomena, without ever asking what the measures mean in human terms. Examples include the nature of the lunar surface, asteroid colors and brightness of the Io aurora, as will be discussed. However, in presenting the "big picture" to the public, and even to other working scientists, it is useful to revisit the Renaissance paradigm. Artists are increasingly working with scientists to translate the understanding of other worlds to the public, and this creates many opportunities for education projects in schools, and for careers in public outreach and science journalism.

  7. Vortex flow in nature and technology

    Lugt, H. J.

    The occurrence and characteristics of vortices in flows are explored comprehensively, including historical observations and representations dated several millenia BC. Attention is given to the development of the scientific concept of vortices, and the basic concepts and kinematics of vortices are reviewed, as are the properties of simple vortices. The genesis and behavior of vorticity is traced through separation, instability, and turbulence. Fluid flow in a rotating system is explored, as are stratification in the ocean and atmosphere, circulations in the atmosphere, ocean, and earth, and the features of single vortices in the atmosphere and oceans. Hurrican formations are investigated, together with extraterrestrial vortices in planetary atmospheres, stars, and galaxies. A plethora of photographs and illustrations is presented, including drawings by Leonardo da Vinci.

    2008-11-01

    Long before C P Snow's two cultures, there was only one. Its supreme embodiment was the great Renaissance master Leonardo da Vinci. Da Vinci saw no barriers between art and science (or what was known as natural philosophy back in the 16th century). His journals were filled with sketches, ideas and observations that testify to the polymath nature of Da Vinci's ingenuity. Da Vinci used artistic inspiration as a path to his inventions, and the observation of the natural world as an intrinsically artistic undertaking. He made thousands of blueprints outlining some of the most impressive inventions ever conceptualized - flying machines, bridges, calculators, tanks, solar-power cells. Most were impractical, few every saw the light of day, but all bore the mark of the master's infinite inventive powers.

  9. Turbulence

    NASA Astrophysics Data System (ADS)

    Frisch, Uriel

    1996-01-01

    Written five centuries after the first studies of Leonardo da Vinci and half a century after A.N. Kolmogorov's first attempt to predict the properties of flow, this textbook presents a modern account of turbulence, one of the greatest challenges in physics. "Fully developed turbulence" is ubiquitous in both cosmic and natural environments, in engineering applications and in everyday life. Elementary presentations of dynamical systems ideas, probabilistic methods (including the theory of large deviations) and fractal geometry make this a self-contained textbook. This is the first book on turbulence to use modern ideas from chaos and symmetry breaking. The book will appeal to first-year graduate students in mathematics, physics, astrophysics, geosciences and engineering, as well as professional scientists and engineers.

    We describe the application of 2D and 3D data acquisition and mutual registration to the conservation of paintings. RGB color image acquisition, IR and UV fluorescence imaging, together with the more recent hyperspectral imaging (32 bands) are among the most useful techniques in this field. They generally are meant to provide information on the painting materials, on the employed techniques and on the object state of conservation. However, only when the various images are perfectly registered on each other and on the 3D model, no ambiguity is possible and safe conclusions may be drawn. We present the integration of 2D and 3D measurements carried out on two different paintings: "Madonna of the Yarnwinder" by Leonardo da Vinci, and "Portrait of Lionello d'Este", by Pisanello, both painted in the XV century.

    Baker, V.

    1991-01-01

    The concept of the hydrological cycle is one of the greatest achievements in the understanding of nature. Leonardo da Vinci seems to have held two concurrent views of the cycle: an external process in which evaporation from ponded areas leads to precipitation and runoff from the land; and an internal process in which subsurface pressures from within the Earth force water upward. Endogenetic hypotheses for valley genesis on Mars maintain the necessary prolonged ground water flows by hydrothermal circulation associated with impact cratering or with volcanism. Ocean formation on Mars was episodic, mostly evidenced by the latest episodes. Coincident cataclysmic flood discharges to the northern plains, probably triggered by Tharsis volcanism, would lead to immense consequences. Potential volumes of ponded water are summarized. The outflow channels have a complex history of flooding events over a prolonged period of planetary history. It is hypothesized that episodic outbursts of concurrent discharge was triggered by planetary scale volcanism. The consequences of such episodes are summarized.

    2008-05-01

    The Leonardo da Vinci pilot projects SUPERCOMET (2001-2004) and SUPERCOMET 2 (2004-2007) developed and tested teacher training materials for active, minds-on learning of electromagnetism and superconductivity at the level of upper secondary school. New multimedia materials for the pupils supported the teacher materials, including a teacher seminar in 4 half-day modules detailing the scientific contents, teaching methods, using ICT in physics teaching and learning, online collaboration and further resources for exploring the selected topics. The aim of these projects were to improve the quality of physics teaching on a European level, involving a combined total of 45 partners in 16 countries, and conducting trials at 67 schools with approx. 230 teachers, 280 trainee teachers and 2200 pupils. New follow-up projects develop hands-on materials for carrying out the activities described in the teacher guide and seminars and additional teacher materials involving modelling, simulations and data logging.

    The current paper is dedicated to present browser-based multimedia-rich software tools and e-learning curriculum to support the design and modeling process of power electronics circuits and to explain sometimes rather sophisticated phenomena. Two projects will be discussed. The so-called Inetele project is financed by the Leonardo da Vinci program of the European Union (EU). It is a collaborative project between numerous EU universities and institutes to develop state-of-the art curriculum in Electrical Engineering. Another cooperative project with participation of Japanese, European and Australian institutes focuses especially on developing e-learning curriculum, interactive design and modeling tools, furthermore on development of a virtual laboratory. Snapshots from these two projects will be presented.

  17. The origin of the vertebrate skeleton

    NASA Astrophysics Data System (ADS)

    Pivar, Stuart

    2011-01-01

    The anatomy of the human and other vertebrates has been well described since the days of Leonardo da Vinci and Vesalius. The causative origin of the configuration of the bones and of their shapes and forms has been addressed over the ensuing centuries by such outstanding investigators as Goethe, Von Baer, Gegenbauer, Wilhelm His and D'Arcy Thompson, who sought to apply mechanical principles to morphogenesis. However, no coherent causative model of morphogenesis has ever been presented. This paper presents a causative model for the origin of the vertebrate skeleton, based on the premise that the body is a mosaic enlargement of self-organized patterns engrained in the membrane of the egg cell. Drawings illustrate the proposed hypothetical origin of membrane patterning and the changes in the hydrostatic equilibrium of the cytoplasm that cause topographical deformations resulting in the vertebrate body form.

  18. Identification of vortices in complex flows

    Chakraborty, P.; Balachandar, S.; Adrian, R. J.

    2007-12-01

    Dating back to Leonardo da Vinci's famous sketches of vortices in turbulent flows, fluid dynamicists for over five centuries have continued to visualize and interpret complex flows in terms of motion of vortices. Nevertheless, much debate surrounds the question of how to unambiguously define vortices in complex flows. This debate has resulted in the availability of many vortex identification criteria---mathematical statements of what constitutes a vortex. Here we review the popularly used local or point- wise vortex identification criteria. Based on local flow kinematics, we describe a unified framework to interpret the similarities and differences in the usage of these criteria. We discuss the limitations on the applicability of these criteria when there is a significant component of vortex interactions. Finally, we provide guidelines for applying these criteria to geophysical flows.

  19. The colour wheels of art, perception, science and physiology

    Colour is not the domain of any one discipline be it art, philosophy, psychology or science. Each discipline has its own colour wheel and this presentation examines the origins and philosophies behind the colour circles of Art, Perception, Science and Physiology (after image) with reference to Aristotle, Robert Boyle, Leonardo da Vinci, Goethe, Ewald Hering and Albert Munsell. The paper analyses and discusses the differences between the four colour wheels using the Natural Colour System® notation as the reference for hue (the position of colours within each of the colour wheels). Examination of the colour wheels shows the dominance of blue in the wheels of art, science and physiology particularly at the expense of green. This paper does not consider the three-dimensionality of colour space its goal was to review the hue of a colour with regard to its position on the respective colour wheels.

  20. Importance of Eugenio Beltrami's hydroelectrodynamics

    As part of a continuing project of bringing the works of Bernhard Riemann and his collaborators directly before the scientific community, we are happy to present translations of two papers by Eugenio Beltrami that were key in the development of hydrodynamics. We have also translated a short portion of Beltrami's attack upon the electrodynamics of James Clerk Maxwell. The first paper develops the work of Hermann Helmholtz (translated in IJFE (Helmholtz 1978)) into a generative treatment of vortices. As the note by Dan Wells in this issue illustrates in connection with his own work, Beltrami's method has proven critical to the treatment of the development of vortices in plasmas, providing a crucial tool for studying what was otherwise dismissed as turbulence. In his introduction to the translations, Dr. Giuseppe Filipponi develops the connection between the discoveries of Beltrami and the Italian tradition of research in hydrodynamics begun by Leonardo da Vinci.

    From Leonardo da Vinci's designs for ball bearings to the incredible engineering wizardry behind the Ferrari, the inventive, inquisitive, and ingenious spirit of the engineer has always lived--and thrived--in Italy. From education to research to product development, Italy has always been regarded as an engineering leader. But does this apply to biomedical engineering (BME)? Despite many successes, questions loom, as they do at engineering schools worldwide. Concerns such as whether BME programs are providing students with enough focused, practical, hands-on training remain at the forefront, as does the question of whether graduates will be able to find jobs in industry after university studies are over. Here, IEEE Pulse explores these topics with Riccardo Pietrabissa, president of the Gruppo Nazionale di Bioingegneria (National Bioengineering Group) and a full professor in the Department of Chemistry, Materials, and Chemical Engineering at Politecnico di Milano.

    Vortex Induced Vibrations Aquatic Clean Energy (VIVACE) is a novel, demonstrated approach to extracting energy from water currents. This invention is based on a phenomenon called Vortex Induced Vibrations (VIV), which was first observed by Leonardo da Vinci in 1504AD. He called it ‘Aeolian Tones.’ For decades, engineers have attempted to prevent this type of vibration from damaging structures, such as offshore platforms, nuclear fuel rods, cables, buildings, and bridges. The underlying concept of the VIVACE Converter is the following: Strengthen rather than spoil vortex shedding; enhance rather than suppress VIV; harness rather than mitigate VIV energy. By maximizing and utilizing this unique phenomenon, VIVACE takes this “problem” and successfully transforms it into a valuable resource for mankind.

    2009-04-01

    The film Taare Zameen Par (Stars upon the Ground) portrays the tormented life at school and at home of a child with dyslexia and his eventual success after his artistic talents are discovered by his art teacher at the boarding school. The film hints at a curious neurocognitive phenomenon of creativity in the midst of language disability, as exemplified in the lives of people like Leonardo da Vinci and Albert Einstein, both of whom demonstrated extraordinary creativity even though they were probably affected with developmental learning disorders. It has been hypothesized that a developmental delay in the dominant hemisphere most likely 'disinhibits' the nondominant parietal lobe, unmasking talents-artistic or otherwise-in some such individuals. It has been suggested that, in remedial training, children with learning disorders be encouraged to develop such hidden talents to full capacity, rather than be subjected to the usual overemphasis on the correction of the disturbed coded symbol operations.

    The ecancer/SAC First International Prostate Cancer Symposium, held in Buenos Aires, included national, regional, and international experts in the field of prostate cancer. More than 200 professionals from a variety of areas (clinical urologists, pathologists, oncologists, biologists, imaging specialists, radiation therapists, and generalist doctors, among others) attended, and they proposed multidisciplinary management of prostate pathology from the start in concordance with the ideas set forth by the organising committee. A radiotherapy workshop was also held during the symposium, in which new techniques and their possible uses were specifically discussed. In addition to the local doctors, Dr Lilian Faroni (COI Group, Rio de Janeiro, Brazil), Dr Leonardo Carmona (Chilean Head and Neck Institute, Chile), and Dr Anthony Addesa (Jupiter Medical Centre, Florida, USA) also participated in this symposium.

    This paper, which is limited to the art of painting, aims to support the idea that a substantial insertion of concepts and methods drawn on dream psychology and dream neuroscience can contribute to the advancements of Neuroesthetics. The historical and scientific reasons are discussed that have determined the so far poor role played by the dream phenomenon in the developments of Neuroesthetics. In the light of recent advancements in psychophysiological research, a method of analyzing artistic products is proposed that is based on the recognition of precise features proper of the dreaming experience. Four examples are given for application of this method, regarding works by Giorgione, Leonardo da Vinci, Vermeer, and Millais, respectively. PMID:26157373

    2013-01-01

    For several of Leonardo da Vinci's paintings, such as The Virgin and Child with St Anne or the Mona Lisa, there exist copies produced by his own studio. In case of the Mona Lisa, a quite exceptional, rediscovered studio copy was presented to the public in 2012 by the Prado Museum in Madrid. Not only does it mirror its famous counterpart superficially; it also features the very same corrections to the lower layers, which indicates that da Vinci and the 'copyist' must have elaborated their panels simultaneously. On the basis of subjective (thirty-two participants estimated painter-model constellations) as well as objective data (analysis of trajectories between landmarks of both paintings), we revealed that both versions differ slightly in perspective. We reconstructed the original studio setting and found evidence that the disparity between both paintings mimics human binocular disparity. This points to the possibility that the two Giocondas together might represent the first stereoscopic image in world history. PMID:24303752

    2016-03-01

    Various changes in the sociopolitical milieu of Italy led to the increasing tolerance of the study of cadavers in the late Middle Ages. The efforts of Mondino de Liuzzi (1276-1326) and Guido da Vigevano (1280-1349) led to an explosion of cadaver-centric studies in centers such as Bologna, Florence, and Padua during the Renaissance period. Legendary scientists from this era, including Leonardo Da Vinci, Andreas Vesalius, Bartolomeo Eustachio, and Costanzo Varolio, furthered the study of neuroanatomy. The various texts produced during this period not only helped increase the understanding of neuroanatomy and neurophysiology but also led to the formalization of medical education. With increased understanding came new techniques to address various neurosurgical problems from skull fractures to severed peripheral nerves. The present study aims to review the major developments in Italy during the vibrant Renaissance period that led to major progress in the field of neurosurgery. PMID:26585723

    There is still uncertainty about the diagnosis and nature of the plague; some scholars have been forced to abandon certainties and be filled with doubts: from believing that the mediaeval Black Plague was, in reality, the bubonic plague (although with unusual characteristics) to stating that there is very little evidence to support a retro-diagnosis. This article looks at this in depth, not only reviewing the historiography but also giving new interpretations which question previous hypotheses through research on images of the time, comparing them to the most recent investigative data. Two primary sources are analysed: Renaissance treaties written by four Italian doctors: Michele Savonarola, Marsilio Ficino, Leonardo Fioravanti and Gioseffo Daciano; and iconography: an illustrated manuscript of the Decameron by Giovanni Boccaccio and a Hebrew Haggadah from the XIVth century. The results are compared to the most recent research on DNA and in micropaleontology. PMID:26399143

    2016-01-01

    The ways in which today's psychoanalysts approach art closely follow the avenues opened by Freud a hundred years ago. Drawing mainly on Freud's studies on Jensen's Gradiva (1907) and on Leonardo da Vinci (1910a), the author examines the main paradigms he used in discussing artistic activity, including his doubts and hesitations. Present-day approaches to art are then examined via a discussion of the advantages and pitfalls of psychobiography, of the case study, and of textual approaches. The author makes a case for the type of interdisciplinary dialogue in which the goal is to establish a cross-fertilization between psychoanalysis and other fields of knowledge while striving to avoid hypersaturation of a work of art in order to foster expansion of the mind.

    The outbreak of syphilis in Europe elicited a variety of responses concerning the disease's origins and cure. In this essay, I examine the theory of the origins of syphilis advanced by the 16th-century Italian surgeon Leonardo Fioravanti. According to Fioravanti, syphilis was not new but had always existed, although it was unknown to the ancients. The syphilis epidemic, he argued, was caused by cannibalism among the French and Italian armies during the siege of Naples in 1494. Fioravanti's strange and novel theory is connected with his view of disease as corruption of the body caused by eating improper foods. His theory of bodily pollution, a metaphor for the corruption of society, coincided with Counter-Reformation concepts about sin and the social order. PMID:11620327

    The historical development of the mechanics of blood flow can be traced from ancient times, to Leonardo da Vinci and Leonhard Euler and up to the present times with increasing biological knowledge and mathematical analysis. In the last two decades, quantitative and numerical methods have steadily given more complete and precise understanding. In the arterial system wave propagation computations based on nonlinear one-dimensional modeling have given the best representation of pulse wave propagation. In the veins, the theory of unsteady flow in collapsible tubes has recently been extensively developed. In the last decade, progress has been made in describing the blood flow at junctions, through stenoses, in bends and in capillary blood vessels. The rheological behavior of individual red blood cells has been explored. A working model consists of an elastic membrane filled with viscous fluid. This model forms a basis for understanding the viscous and viscoelastic behavior of blood. PMID:7024641

The segment joins two others for a campaign of prelaunch processing activities. CSA's first contribution to the International Space Station (ISS), the SSRMS is the primary means of transferring payloads between the orbiter payload bay and the ISS for assembly. The 56-foot-long robotic arm includes two 12- foot booms joined by a hinge. Seven joints on the arm allow highly flexible and precise movement. Latching End Effectors are mounted on each end of the arm for grappling. Video cameras mounted on the booms and end effectors will give astronauts maximum visibility for operations and maintenance tasks on the ISS. The SSRMS is scheduled to be launched aboard Space Shuttle Endeavour on STS-100, currently planned for July 2000.

  6. Soft matter dynamics: Accelerated fluid squeeze-out during slip

    Hutt, W.; Persson, B. N. J.

    2016-03-01

    Using a Leonardo da Vinci experimental setup (constant driving force), we study the dependency of lubricated rubber friction on the time of stationary contact and on the sliding distance. We slide rectangular rubber blocks on smooth polymer surfaces lubricated by glycerol or by a grease. We observe a remarkable effect: during stationary contact the lubricant is only very slowly removed from the rubber-polymer interface, while during slip it is very rapidly removed resulting (for the grease lubricated surface) in complete stop of motion after a short time period, corresponding to a slip distance typically of order only a few times the length of the rubber block in the sliding direction. For an elastically stiff material, poly(methyl methacrylate), we observe the opposite effect: the sliding speed increases with time (acceleration), and the lubricant film thickness appears to increase. We propose an explanation for the observed effect based on transient elastohydrodynamics, which may be relevant also for other soft contacts.

    The ecancer/SAC First International Prostate Cancer Symposium, held in Buenos Aires, included national, regional, and international experts in the field of prostate cancer. More than 200 professionals from a variety of areas (clinical urologists, pathologists, oncologists, biologists, imaging specialists, radiation therapists, and generalist doctors, among others) attended, and they proposed multidisciplinary management of prostate pathology from the start in concordance with the ideas set forth by the organising committee. A radiotherapy workshop was also held during the symposium, in which new techniques and their possible uses were specifically discussed. In addition to the local doctors, Dr Lilian Faroni (COI Group, Rio de Janeiro, Brazil), Dr Leonardo Carmona (Chilean Head and Neck Institute, Chile), and Dr Anthony Addesa (Jupiter Medical Centre, Florida, USA) also participated in this symposium.

    2003-01-01

    The Multiple Autonomous Discrete Event Controllers for Constellations (MADECC) project is an effort within the National Aeronautics and Space Administration Goddard Space Flight Center's (NASA/GSFC) Information Systems Division to develop autonomous positioning and attitude control for constellation satellites. It will be accomplished using traditional control theory and advanced coordination algorithms developed by the Johns Hopkins University Applied Physics Laboratory (JHU/APL). This capability will be demonstrated in the discrete event control test-bed located at JHU/APL. This project will be modeled for the Leonardo constellation mission, but is intended to be adaptable to any constellation mission. To develop a common software architecture. the controllers will only model very high-level responses. For instance, after determining that a maneuver must be made. the MADECC system will output B (Delta)V (velocity change) value. Lower level systems must then decide which thrusters to fire and for how long to achieve that (Delta)V.

    To understand what will happen in the future one must draw on the experience of those from the past who have tried to predict what is happening now. The paper develops a taxonomy of visionaries of futurologist; the advocates of historical determinism, who come from both the left, such as Marx, and the right, such as Toffler and Fukuyama; the scientist, ranging from Leonardo da Vinci to Arthur C. Clarke, and the pragmatists, who seek to learn from evidence and the experience of others. These will be examined in turn and the frequent failings of the first three will be illustrated. Drawing on experience in a variety of European countries it will be concluded that our best hope is to learn from each other and from empirical evidence. The article will conclude with a review of some of the challenges which are either predictable but being ignored or totally unpredictable. PMID:11623489

  19. The extent of man from Vitruvius to Marfan.

    PubMed

    Schott, G D

    It is frequently stated that patients with Marfan's syndrome have an arm span greater than height. This implies a characteristic different from the proportions in normal adult man, in whom span and height are often thought to be equal. Such equality of span and height, which allows man to be portrayed within a square, has been a widely held concept, immortalised by Leonardo da Vinci, that dates from the Roman Vitruvius. However, in the past two hundred years, anthropometry has shown that span exceeds height in 59-78% of normal adult white men. Thus not only is the classic concept of equality of span and height generally incorrect, but also a span greater than height cannot be considered characteristic of Marfan's syndrome. Paradoxically, in some affected individuals, Vitruvian equality of height and span may occur. PMID:1361608

    The goal of this study was to determine the repeatability of gait parameters measured by a force plate gait analysis system (Leonardo Mechanograph(®) GW) in healthy children. Nineteen healthy children and adolescents (age range: 7-17 years) walked at a self-selected speed on an 11-m-long walkway. Vertical ground reaction forces were measured in the central 6 m of the walkway. Each participant performed three blocks of three trials while walking barefoot and three blocks of three trials while wearing shoes. There were no differences between trials within each condition. All force and spatiotemporal parameters had intraclass correlation coefficients above 0.87 and coefficients of variation in the order of 1-6%. In this group of healthy children and adolescents, gait analysis with a force plate system produced repeatable intra-day results. PMID:23360226

    The science of self-assembly has undergone a radical shift from asking questions about why individual components self-organize into ordered structures, to manipulating the resultant order. However, the quest for far-reaching nanomanufacturing requires addressing an even more challenging question: how to form nanoparticle (NP) structures with designed architectures without explicitly prescribing particle positions. Here we report an assembly concept in which building instructions are embedded into NPs via DNA frames. The integration of NPs and DNA origami frames enables the fabrication of NPs with designed anisotropic and selective interactions. Using a pre-defined set of different DNA-framed NPs, we show it is possible to design diverse planar architectures, which include periodic structures and shaped meso-objects that spontaneously emerge on mixing of the different topological types of NP. Even objects of non-trivial shapes, such as a nanoscale model of Leonardo da Vinci's Vitruvian Man, can be self-assembled successfully. PMID:27554413

    Using Domain Requirements to Achieve Science-Oriented Provenance Eric Stephan1 Todd Halter1 Terence Critchlow1 Paulo Pinheiro da Silva2 Leonardo Salayandia2 1 Pacific Northwest National Laboratory, Richland WA, USA 2 University of Texas at El Paso, El Paso TX, USA Abstract. The US Department of Energy (DOE) Atmospheric Radi- ation Measurement Program (ARM) is adopting the use of formalized provenance to support observational data products produced by ARM operations and relied upon by researchers. Because of the diversity of needs in the climate community provenance will need to be conveyed in a domain-oriented context. This paper explores a use case where semantic abstract workflows (SAW) are employed as a means to filter, aggregate, and contextually describe the historical events responsible for the ARM data product the scientist is relying upon.

    The film Taare Zameen Par (Stars upon the Ground) portrays the tormented life at school and at home of a child with dyslexia and his eventual success after his artistic talents are discovered by his art teacher at the boarding school. The film hints at a curious neurocognitive phenomenon of creativity in the midst of language disability, as exemplified in the lives of people like Leonardo da Vinci and Albert Einstein, both of whom demonstrated extraordinary creativity even though they were probably affected with developmental learning disorders. It has been hypothesized that a developmental delay in the dominant hemisphere most likely ‘disinhibits’ the nondominant parietal lobe, unmasking talents—artistic or otherwise—in some such individuals. It has been suggested that, in remedial training, children with learning disorders be encouraged to develop such hidden talents to full capacity, rather than be subjected to the usual overemphasis on the correction of the disturbed coded symbol operations.

  10. The thread of depression throughout the life and works of Leo Tolstoy.

    Tolstoy, the author of two masterpieces, War and Peace and Anna Karenina, remains a writer of genius. Yet, after writing War and Peace, his existence had been torn apart by a serious depression. This depression, which was melancholic in character, almost destroyed him and, once he had finished Anna Karenina, led him to want to renounce not only sexuality but also literary creation and material possessions. Through examining Tolstoy's life and work, the author tries to uncover the underground paths of this depression, which emerged brutally in the middle of his life, and to understand why his creative genius dried up. Like Leonardo da Vinci, Tolstoy turned away from his artistic work, declaring that 'art is not only useless but even harmful', and thereafter devoted himself to philosophical, political and religious writings. These new sublimations would help him to recover his health. PMID:12040704
