    Muchos de nuestros amables lectores nos han preguntado acerca de la portada del número anterior, en la cual presentamos un cuadro poco conocido de Pablo Ruiz Picasso. Su estilo clásico sorprendió a quienes están acostumbrados a reconocer el arte del genio español en las "Demoiselles D'Avignon" o en "Guernica".

    Por eso hemos decidido dar algunas explicaciones al respecto del cuadro y profundizar un poco en la vida del artista, sin las pretensiones de tratar el tema exhaustivamente, pues sería, como lo ha sido una tarea muy larga y para manos de expertos.
    El cuadro "Ciencia y Caridad", fue pintado por Picasso en 1897, es decir a la edad de 16 años y con él recibió una mención honorífica en Madrid. En un lecho pobre se ve a la enferma demacrada, que refleja en sus ojos, no sólo su gran debilidad, sino la tristeza de dejar -a su pequeño hijo. A su lado se encuentra la Ciencia, representada por el médico, preocupado por los síntomas de la paciente y por su curación. No parece prestar atención a lo que pasa
    al otro lado de la cama, en donde una rubicunda religiosa, que representa la Caridad, extiende a la enferma un poco de alimento y mantiene en brazos al pequeño, quien, sin comprender el drama, se aferra a la monja. la cual, parece estar cumpliendo su deber sólo como una parte de su rutina. Hay que anotar que el modelo para la figura del médico fue el mismo padre de Picasso. El planteamiento del cuadro es sencillo, su tratamiento y composición clásicos, sin duda es una bella obra, que sorprende en un muchacho de la corta edad a que lo realizó el autor.

    ¿Qué había sucedido en la vida de Picasso antes de realizar esta obra, y qué pasó después? Vale la pena describirlo...

    Leonardo da Vinci's texts consist almost exclusively of scientific notes. Working on a book on Leonardo's art, I studied all Leonardo's published texts carefully for any new information. In some prefaces I came to suspect that Leonardo might have suffered from dyslexia. This article considers the question of whether it is possible to find indications of dyslexia in Leonardo's texts and in the accounts of his life.

En él consagramos no solamente a la Anatomía Patológica como especialidad, ausente muchos lustros de este recinto bogotano, desde la época de su numerario y posterior Presidente Dr. Juan Pablo Llinás, sino especialmente a la persona que con su dedicación, su enseñanza y su ejemplo ha servido para darle la categoría que corresponde a esta rama del saber médico, formando generaciones de nuevos patólogos que han extendido su conocimiento por todo lo largo y ancho de nuestra accidentada geografía.

    Para reconocer la dimensión exacta de sus contribuciones, habría que mirar en qué estado se encontraba la anatomía patológica en Colombia al finalizar la década de los años cuarentas cuando Egon se gradúa de la Universidad Nacional, en 1947, con una tesis calificada como meritoria. Hasta la época de la lla. Guerra Mundial toda nuestra enseñanza anatomopatológica tomaba sus raíces en Francia, directamente derivada de Bichat y de Cruveilhier y admirablemente suplementada por los textos de anatomía descriptiva de Testut – Latarjet, que todo estudiante debía memorizar en dos años de agobiador ejercicio mnemotécnico. Allí, desde los bancos de disección anatómica, se barruntaban las variaciones de lo normal a lo patológico, que simultámeamente y a partir del segundo año de carrera se entrelazaban con las preparaciones histopatológicas.

    Sin embargo, a pesar de que la escuela fisiopatológica se había originado en la Francia de mediados del ochocientos con Claude Bernard y sus seguidores, la anatomopatológia seguía teniendo la misma rigidez descriptiva de los anatomistas clásicos, sin que tratara de orientarse al estudiante, las más de las veces, hacia las

    Dr. José Félix Patiño como Presidente de la Academia Nacional de Medicina.

    Señores Académicos, señoras, señores:

    (Santafé de Bogotá, marzo 19 de 1998


    Como un "Fenómeno del Niño" y con el ímpetu emocional de esas sagas cíclicas que nos recordara
    vívidamente "Cien Años de Soledad" se repite, a los ocho años, una ceremonia en que dos de sus
    actores son los mismos, sólo que con orden inverso. Esta vez un hombre salido de las filas académicas, sin otro mérito que su capacidad de reconocimiento y afecto, tiene como honroso encargo pronunciar el discurso de orden en la posesión de José Félix Patiño como Presidente de la Academia Nacional de Medicina para los dos últimos años del milenio, rodeado de una dignísima Junta Directiva y sucediendo a otro hombre de cualidades eximias, que ha dirigido uno de los cuatrienios más ilustres por
    los que haya pasado la corporación.

    En esa otra época, 1990, fue un académico ya cargado de honores y de merecimientos quien pronunciara gallardamente el discurso de orden durante el acto de mi posesión como Presidente, en el paraninfo de la Academia Colombiana de la Lengua.
    Denominador común era y sigue siendo el mutuo bagaje de una amistad ininterrumpida de más de
    cuarenta años, que es el que me lleva a pronunciar estas palabras, cargadas como nunca de admiración, de respeto y de cariño.

    Porque la nutrida votación que llevó al académico Patiño a salir electo con el 95% de los votos,
    fenómeno casi nunca antes visto en los anales de nuestra venerable Academia, no es sino la expresión
    unánime de confianza por un hombre que, ya alcanzada la "edad bíblica" --como él mismo
    lo dijera en sus vivaces memorias del año pasado- conserva la chispa de su infatigable intelecto,
    siempre ávido para enseñar y aprender; y mantiene la integridad física y el ánimo del cirujano de

    Leonardo was an advocate of the intromission theory of vision. Light rays from the object to the eye caused visual perceptions which were transported to the brain ventricles via a hollow optic nerve. Leonardo introduced wax injections to explore the ventricular system. Perceptions were assumed to go to the "senso comune" in the middle (3rd) ventricle, also the seat of the soul. The processing station "imprensiva" in the anterior lateral horns together with memory "memoria" in th posterior (4th) ventricle integrated the visual perceptions to visual experience. - Leonardo's sketches with circular lenses in the center of the eye reveal that his dependence on medieval optics prevailed over anatomical observations. Drawings of the anatomy of the sectioned eye are missing although Leonardo had invented a new embedding technique. In order to dissect the eye without spilling its contents, the eye was first boiled in egg white and then cut. The procedure was now repeated and showed that the ovoid lens after boiling had become spherical. - Leonardo described that light rays were refracted and reflected in the eye but his imperfect anatomy prevented a development of physiological optics. He was, however, the first to compare the eye with a pin-hole camera (camera obscura). Leonardo's drawings of the inverted pictures on the back wall of a camera obscura inspired to its use as an instrument for artistic practice. The camera obscura was for centuries a model for explaining human vision.

    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

    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

    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.

The book was dedicated and presented to the Emperor at Pisa in 1225. Dating back to the 13th century the book exhibits the early and continued fascination of men with our number system and the relationship among numbers

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

    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.

    2000-01-01

    Leonardo-BRDF (Bidirectional Reflectance Distribution Function) is a new 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 flight 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 Lambert 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.

    Nuevamente nos reunimos aquí, en este noble recinto de la Academia Colombiana de la Lengua, esta vez para conmemorar, en fecha y hora casi exactas, los cien años de la promulgación de la ley organica que tiene existencia legal a nuestra Academia. Y digo existencia legal, porque ella ya existía en el espiritu y en las realizaciones de ese puñado de medicos bogotanos de finales del siglo XIX que, encabezados y guiados por Manuel Plata Azuero, Leoncio Barreto, Nicolas Osorio y Abraham Aparicio, entre otros, se habían congregado 18 años atras para fundar la Sociedad de Medicina y Ciencias Naturales que ahora, por decisión soberana del Congreso de la Republica,se tornaba en Academia Nacional de Medicina, el 22 de Noviembre de 1890.

    Es una fecha memorable, que nos obliga a mirar retrospectiva y prospectivamente y a preguntarnos que somos y que representamos nosotros, académicos, en el contexto de un siglo de existencia. Porque no podemos contentamos solamente con vivir de las glorias del pasado y decir que nos adueñamos, apenas, de un legado que otras generaciones, quizas mas objetivas y mas ambiciosas, construyeron pedazo a pedazo para nosotros. No. Este es un momenta que nos impele a un examen de conciencia y, sobre todo, a reflexionar sobre el papel que nuestra clase médica directiva viene ejerciendo y tendra que ejercer, ineluctablemente, en los destinos de la salud de Colombia.

    ¿Por que razón? Porque vivimos espocialmente un momento de cambio. Cambio que seguramente experimentaron y sintieron tambien los fundadores de nuestra Academia cuando, en las postrimerías del siglo XIX, se dieron cuenta de que, mientras en el mundo operaba a toda marcha la revolución industrial y se vislumbraba en el horizonte la caída de los imperios y de las monarquias, la medicina comenzaba lentamente tambien a remover sus bases anatomo-clínica y fisio-patológica, que habían funcionado ya durante mas de un siglo, y a entrar de lleno en la era etiopatológica con el advenimiento de Pasteur, de Koch y de la microbiología.Y que al tiempo, gracias a los avances de la anestesia, la antisepsia
    y la asepsia, se iba hacienda cada vez mas procedimental, mas operatoria y por lo tanto mas curativa...

    Leonardo da Vinci's detailed drawings are justly celebrated; however, less well known are his accounts of the structures and functions of the organs. In this paper, we focus on his illustrations of the heart, his conjectures about heart and blood vessel function, his experiments on model systems to test those conjectures, and his unprecedented conclusions about the way in which the cardiovascular system operates. In particular, da Vinci seems to have been the first to recognize that the heart is a muscle and that systole is the active phase of the pump. He also seems to have understood the functions of the auricles and pulmonary veins, identified the relationship between the cardiac cycle and the pulse, and explained the hemodynamic mechanism of valve opening and closure. He also described anatomical variations and changes in structure and function that occurred with age. We outline da Vinci's varied career and suggest ways in which his personality, experience, skills and intellectual heritage contributed to these advances in understanding. We also consider his influence on later studies in anatomy and physiology. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

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

    Science.gov (United States)

    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.

    Leonardo da Vinci (1452-1519), world-renowned Italian renaissance master, is known for his contributions to, and broad interests in science and art. The objective of this work is to demonstrate the extent of his science by applying the use of his concepts to current models of foot and ankle mechanics. The art and science of Leonardo Da Vinci were extensively analyzed by reviewing his original drawings and hand written notebooks as well as their English translation. Current medical journals including the topics of foot, ankle, and biomechanics were reviewed for modern evidence and application of his concepts. The library of Michigan State University and the electronic library of the Royal Library at Windsor Castle were extensively utilized. From the depths of Santa Maria Nuova Hospital in Florence and Santo Spirito Hospital in Rome, through his commentary and anatomical drawings of around 30 cadaver dissections he performed, Leonardo da Vinci expressed his concept of foot and ankle anatomy and mechanics. He laid forth concepts, which vary little from current theories including those of proportion, statics and joint stability, sesamoid biomechanics, and structural support of the foot. Leonardo da Vinci, by combining an interest in anatomy and a gift of genius and artistic ability laid a foundation of foot and ankle anatomy and mechanics that have been applied in modern clinical sciences. Leonardo in this way made important contributions to the practice of foot and ankle orthopedics.

  19. Leonardo da Vinci: the search for the soul.

    Science.gov (United States)

    Del Maestro, R F

    1998-11-01

    The human race has always contemplated the question of the anatomical location of the soul. During the Renaissance the controversy crystallized into those individuals who supported the heart ("cardiocentric soul") and others who supported the brain ("cephalocentric soul") as the abode for this elusive entity. Leonardo da Vinci (1452-1519) joined a long list of other explorers in the "search for the soul." The method he used to resolve this anatomical problem involved the accumulation of information from ancient and contemporary sources, careful notetaking, discussions with acknowledged experts, and his own personal search for the truth. Leonardo used a myriad of innovative methods acquired from his knowledge of painting, sculpture, and architecture to define more clearly the site of the "senso comune"--the soul. In this review the author examines the sources of this ancient question, the knowledge base tapped by Leonardo for his personal search for the soul, and the views of key individuals who followed him.

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

    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.

    Leonardo da Vinci's face symmetry derives from 3 equal craniofacial segments: trichion-nasion (tn), which represents the superior third of the face, nasion-subnasal (ns) that is the medium third of the face, and subnasal-gnathion (sg) that is the length of the lower third of the face. It has been reported that adult subjects with celiac disease (CD) can be identified on the basis of a greater extension of the forehead in comparison to the medium third of the face, with a high tn/ns ratio. The aim of the present study was to investigate the correlation between facial asymmetry and CD in childhood and adulthood. We studied 126 biopsy-proven patients with CD (76 children and 50 adults) and 102 healthy controls (43 children and 59 adults). Their faces were photographed; the pictures were edited using a software program to calculate the facial segments. The tn length was significantly different between adult celiac and adult controls (7.43 ± 1.46 cm vs 6.38 ± 1.73 cm, P = 0.001). The cutoff of 6.5 cm tn, derived from receiver operating characteristic curve analysis, identified 43 of 50 patients (sensitivity 86%), but 34 of 59 controls were positive (specificity 54.2%). The positive predictive value was 56%; however, the tn/ns ratio was not significantly different between celiacs and controls. Neither the tn length nor the tn/ns ratio in celiacs correlated to the time of gluten exposure. Adults, but not children, with celiac disease show a forehead extension significantly greater than controls, but this test's specificity appears too low to be used in the screening of CD.

  7. LEONARDO DA VINCI AND THE ORIGIN OF SEMEN.

    Science.gov (United States)

    Noble, Denis; DiFrancesco, Dario; Zancani, Diego

    2014-12-20

    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.

  10. Volcanic hazard maps of the Nevado del Ruiz volcano, Colombia

    Science.gov (United States)

    Parra, Eduardo; Cepeda, Hector

    1990-07-01

    Although the potential hazards associated with an eruption of Nevado del Ruiz volcano were known to civil authorities before the catastrophic eruption there in November 1985, their low perception of risk and the long quiescent period since the last eruption (140 years), caused them to wait for stronger activity before developing an eruption alert system. Unfortunately, the eruption occurred suddenly after a period of relative quiet, and as a result more than 25,000 people were killed. Although it was accurate and reasonably comprehensive, the hazard map that existed before the eruption was poorly understood by the authorities and even less so by the general population, because the scientific terminology and probabilistic approach to natural hazards were unfamiliar to many of them. This confusion was shared by the communication media, which at critical times placed undue emphasis on the possibility of lava flows rather than on the more imminent threat from mudflows, in keeping with the popular but often inaccurate perception of volcanic eruptions. This work presents an updated hazard map of Nevado del Ruiz that combines information on various hazardous phenomena with their relative probability of occurrence in order to depict numerical "hazard levels" that are easily comprehensible to nonspecialists and therefore less susceptible to misinterpretation. The scale of relative risk is arbitrary, ranging from five to one, and is intended to provide an intuitive indication of danger to people, property and crops. The map is meant to facilitate emergency preparedness and management by political and civil authorities, to educate the public concerning volcanic hazards and to assist in land-use planning decisions.

  13. Leonardo da Vinci and His Contributions to Cartography

    Directory of Open Access Journals (Sweden)

    Branko Puceković

    2013-12-01

    Full Text Available The archetypal Renaissance figure Leonardo da Vinci was truly a universal man (Ital. – uomo universale. There is no area of human activity that failed to attract his attention, or that does not bear a trace of his deliberations. In the field of fine art, Leonardo is famous for his masterpieces: the Mona Lisa, the Last Supper, the Virgin of the Rocks, and other, unfinished works, for example, St. Jerome in the Wilderness, and the Adoration of the Magi. He did not leave any works of sculpture, though he did create sketches and drawings. His legacy includes approximately 13,000 sheets of notes and drawings of anatomy, architecture, war and flying machines, plants and animals, all annotated in a reversed mirror-script. In his works of art, he brought his compositions to perfection by using the principles of perspective and the techniques of chiaroscuro and sfumato. Leonardo designed war machines and produced several plans and topographical maps for the powerful men of his time, under whose patronage he worked, such as dukes, kings and popes. This article presents a brief account of his most famous cartographical works: the plan of Imola, three topographic maps of Tuscany, the Chiana valley, the Pontine Marshes and western Tuscany, and a world map (Mappa Mundi. Leonardo skilfully made use of his fascination with landscapes, incorporating them as backdrops in his masterpieces.

  18. Leonardo da Vinci and the first hemodynamic observations.

    Science.gov (United States)

    Martins e Silva, J

    2008-02-01

    Leonardo da Vinci was a genius whose accomplishments and ideas come down to us today, five centuries later, with the freshness of innovation and the fascination of discovery. This brief review begins with a summary of Leonardo's life and a description of the most important works of art that he bequeathed us, and then concentrates on his last great challenge. There was a point at which Leonardo's passion for art gave way to the study of human anatomy, not only to improve his drawing but to go beyond what had been simply a representation of form to understand the underlying functioning. Among his many interests, we focus on his study of the heart and blood vessels, which he observed carefully in animals and human autopsies, and reproduced in drawings of great quality with annotations of astonishing acuteness. The experience that he had acquired from observing the flow of water in currents and around obstacles, and the conclusions that he drew concerning hydrodynamics, were central to his interpretation of the mechanisms of the heart and of blood flow, to which he devoted much of his time between 1508 and 1513. From these studies, immortalized in drawings of great clarity, come what are acknowledged to be the first hemodynamic records, in which Leonardo demonstrates the characteristics of blood flow in the aorta and great vessels and the importance of blood reflux and the formation of eddies in the sinus in aortic valve his assiduous and careful observations, and his subsequent deductions, Leonardo put forward detailed findings on hemodynamic questions that advanced technology has only recently enabled us to confirm.

    2004-06-01

    This study confirms Leonardo's claim to have experimented on the bovine eye to determine the internal anatomy of the eye. The experiment, as described by Leonardo, was repeated in our laboratory. The study further discusses Leonardo's primary interest in the study of the eye (especially the lens), to determine how the image of an object which enters the eye in an inverted form is righted. The study shows the evolution of Leonardo's understanding of the anatomy and the physiology of vision. Initially, in keeping with his reading of the literature, the lens was placed in the centre but he made it globular. Later he promulgated two theories, reflection from the uvea and refraction within the lens to explain reversal of the image in the eye. Subsequently he rejected the first theory and, putting credence in the second theory, experimented (1509) to show that the lens is globular and is centrally placed. The fact that the present knowledge about the lens is at variance from his findings is not because he did not carry out the experiment, as suggested by some modern authors, but because of the limitation of the techniques available to him at the time.

  2. Morphology of floral papillae in Maxillaria Ruiz & Pav. (Orchidaceae).

    Davies, K L; Turner, M P

    2004-01-01

    The labellar papillae and trichomes of Maxillaria Ruiz & Pav. show great diversity. Although papillae also occur upon other parts of the flower (e.g. column and anther cap), these have not yet been studied. Labellar trichomes of Maxillaria are useful in taxonomy, but hitherto the taxonomic value of floral papillae has not been assessed. The aim of this paper is to describe the range of floral papillae found in Maxillaria and to determine whether papillae are useful as taxonomic characters. Light microscopy, histochemistry, low-vacuum scanning and transmission electron microscopy. A total of 75 taxa were studied. Conical papillae with rounded or pointed tips were the most common. The column and anther cap usually bear conical, obpyriform or villiform papillae, whereas those around the stigmatic surface and at the base of the anther are often larger and swollen. Labellar papillae show greater diversity, and may be conical, obpyriform, villiform, fusiform or clavate. Papillae may also occur on multiseriate trichomes that perhaps function as pseudostamens. Labellar papillae contain protein but most lack lipid. The occurrence of starch, however, is more variable. Many papillae contain pigment or act as osmophores, thereby attracting insects. Rewards such as nectar or a protein-rich, wax-like, lipoidal substance may be secreted by papillae onto the labellar surface. Some papillae may have a protective role in preventing desiccation. Species of diverse vegetative morphology may have identical floral papillae, whereas others of similar vegetative morphology may not. Generally, floral papillae in Maxillaria have little taxonomic value. Nevertheless, the absence of papillae from members of the M. cucullata alliance, the occurrence of clavate papillae with distended apices in the M. rufescens alliance and the presence of papillose trichomes in some species may yet prove to be useful.

  4. The 1985 Nevado del Ruiz volcano catastrophe: anatomy and retrospection

    Science.gov (United States)

    Voight, Barry

    1990-12-01

    This paper seeks to analyze in an objective way the circumstances and events that contributed to the 1985 Nevado del Ruiz catastrophe, in order to provide useful guidelines for future emergencies. The paper is organized into two principal parts. In the first part, an Anatomy of the catastrophe is developed as a step-by-step chronicle of events and actions taken by individuals and organizations during the period November 1984 through November 1985. This chronicle provides the essential background for the crucial events of November 13. This year-long period is broken down further to emphasize important chapters: the gradual awareness of the awakening of the volcano; a long period of institutional skepticism reflecting an absence of credibility; the closure of the credibility gap with the September 11 phreatic eruption, followed by an intensive effort to gird for the worst; and a detailed account of the day of reckoning. The second part of the paper, Retrospection, examines the numerous complicated factors that influenced the catastrophic outcome, and attempts to cull a few "lessons from Armero" in order to avoid similar occurrences in the future. In a nutshell, the government on the whole acted responsibly but was not willing to bear the economic or political costs of early evacuation or a false alarm. Science accurately foresaw the hazards but was insufficiently precise to render reliable warning of the crucial event at the last possible minute. Catastrophe was therefore a calculated risk, and this combination - the limitations of prediction/detection, the refusal to bear a false alarm and the lack of will to act on the uncertain information available - provided its immediate and most obvious causes. But because the crucial event occurred just two days before the Armero emergency management plan was to be critically examined and improved, the numerous circumstances which delayed progress of emergency management over the previous year also may be said to have

    Full Text Available En el texto se describe el funcionamiento de la casa comercial Uribe Ruiz Hermanos que operó en Rionegro, Medellín y Manizales, localidades antioqueñas, desde 1894 hasta 1916. En Colombia desde medidos de siglo XIX las oportunidades para incrementar el comercio de exportación de materias primas e importación de manufacturas aumentaron. Antioquia fue una de las regiones más dinámicas del país en cuanto al desarrollo de relaciones comerciales e integración de mercados locales con centros urbanos gracias al comercio. Pedro y Estanislao Uribe Ruiz, fundadores de Uribe Ruiz Hermanos, organizaron su casa de comercio a través de la red parental con lo que aseguraron la continuidad del negocio y la confianza para invertir en diversos campos económicos, como era costumbre entre otros comerciantes antioqueños durante el siglo XIX.

  8. Leonardo da Vinci: engineer, bioengineer, anatomist, and artist.

    Leonardo da Vinci (1452-1519) enjoys a reputation as one of the most talented people of all time in the history of science and the arts. However, little attention has been given to his contributions to physiology. One of his main interests was engineering, and he was fascinated by structural problems and the flow patterns of liquids. He also produced a large number of ingenious designs for warfare and a variety of highly original flying machines. But of particular interest to us are his contributions to bioengineering and how he used his knowledge of basic physical principles to throw light on physiological function. For example, he produced new insights into the mechanics of breathing including the action of the ribs and diaphragm. He was the first person to understand the different roles of the internal and external intercostal muscles. He had novel ideas about the airways including the mode of airflow in them. He also worked on the cardiovascular system and had a special interest in the pulmonary circulation. But, interestingly, he was not able to completely divorce his views from those of Galen, in that although he could not see pores in the interventricular septum of the heart, one of his drawings included them. Leonardo was a talented anatomist who made many striking drawings of the human body. Finally, his reputation for many people is based on his paintings including the Mona Lisa that apparently attracts more viewers than any other painting in the world.

    2009-01-01

    The aim of this article is to reflect on the relationship between art and science so far as it concerns a symposium on neurosciences. We undertake a historical overview of that relationship, paying particular attention to the sui generis case of Leonardo da Vinci, who very often is regarded as the man who worked on art and science with equal ease. We then explain why his idea of merging these two forms of knowledge failed, considering the clear-cut distinction between art and science in his time. With this clarification, we explore the matter today. We look at Raphael's The Transfiguration, in which the representation of the possessed boy is seen by neuroscientists as indicative of an epileptic seizure. We also look at the ideas of neuroscientists Semir Zeki and Vilayanur Ramachandran, who study particular aspects of brain function and suggest a new merging of art and science.

  12. The first marriage of despot Leonardo III Tocco

    2006-01-01

    Full Text Available The marriage between Leonardo III — the last member of the Tocco family who ruled the Heptanese (1448-1479 — and Milica Branković, the daughter of the Serbian Despot Lazar Branković and Helen Palaiologos, concluded in Dubrovnik on May 1 1463, is an intriguing issue: it was concluded under unusual circumstances, and its significance was variously presented by the couple's earlier and later contemporaries. An analysis of several historical sources (mainly those of documentary character, also some of a narrative nature shows that, despite the belittlement of its significance made by some of the pair's contemporaries, the marriage was generally seen as a prospective alliance, designed not only to satisfy the existential needs of the couple but also to enhance the interests of various important political factors of the time: Thomas Palaiologos, the authorities of Dubrovnik, the Roman Curia and Cardinal Bessarion. As widely known, the political prospectives opened by this marriage were not fully accomplished due to the short duration of this relationship (Milica died soon after the wedding. Yet this conjugal alliance proved useful for the Tocco party even after its conclusion. In the time following Leonardo's flight from the Ottomans to Naples (after 1479, he referred to the lineage with Milica as an alliance with the Byzantine imperial family, supposedly in order to achieve certain benefices from the Italian environment where he repatriated. In parallel to the analysis of the sources about the motives and significance of the first marriage of the last Tocco despot, in this paper I also deal with several pro-sopographic and topographic details of regional importance, mentioned on the occasion of the Tocco-Brankovic wedding ceremony (e.g. Bishop of Bologna Blasius Constantii Paliki, etc. .

    A synopsis of Plazia Ruiz & Pav. (Onoserideae, Asteraceae) is presented, including the description of a new species, Plazia robinsonii M.O.Dillon & Sagást., from a locality c. 20 kms west of Huamachuco, Department of La Libertad in northern Peru. It most closely resembles Plazia conferta Ruiz & Pav., a narrow endemic from central Peru some 450 km to the south; however, the latter species has larger leaves and smaller capitula. Plazia is a small genus of four species confined to the Andean Cordillera of Peru, Bolivia, Chile, and Argentina. A distribution map of the four species, an illustration of the new species, a photograph of the holotype, and a key to species are provided.

    Full Text Available We intend to investigate and delimit, a certain period of film production by Raúl Ruiz, made in Chile during the last decade. Ruiz will install a type of filmic narrative inspired by the rescue of some popular stories, and of a certain Chilean literature of fines of the nineteenth and early twentieth centuries. If in the mid-90s, in his first Poetics of cinema, he insisted on resisting the model imposed by the industrial cinema (Hollywood, of what narration determines the image, with this series of films that work, unique way of narration in which the image becomes a determining principle. It is thus that the narrative that promotes Ruiz is a search of the remains or vestiges of experiences that do not form a part of any type of national History of monumental character, since they can be transmitted not from an image reported of the past, but from his transmission a permanent but inactual image develops. This image is our objective, since it is a construction of a type of singular narration that has an inseparable link to a thematic and aesthetic relationship with Chile

    The second Gaia data release, Gaia DR2, encompasses astrometry, photometry, radial velocities, astrophysical parameters (stellar effective temperature, extinction, reddening, radius, and luminosity), and variability information plus astrometry and photometry for a sample of pre-selected bodies in the solar system. The data collected during the first 22 months of the nominal, five-year mission have been processed by the Gaia Data Processing and Analysis Consortium (DPAC), resulting into this second data release. A summary of the release properties is provided in Gaia Collaboration et al. (2018b). The overall scientific validation of the data is described in Arenou et al. (2018). Background information on the mission and the spacecraft can be found in Gaia Collaboration et al. (2016), with a more detailed presentation of the Radial Velocity Spectrometer (RVS) in Cropper et al. (2018). In addition, Gaia DR2 is accompanied by various, dedicated papers that describe the processing and validation of the various data products. Four more Gaia Collaboration papers present a glimpse of the scientific richness of the data. In addition to this set of refereed publications, this documentation provides a detailed, complete overview of the processing and validation of the Gaia DR2 data. Gaia data, from both Gaia DR1 and Gaia DR2, can be retrieved from the Gaia archive, which is accessible from https://archives.esac.esa.int/gaia. The archive also provides various tutorials on data access and data queries plus an integrated data model (i.e., description of the various fields in the data tables). In addition, Luri et al. (2018) provide concrete advice on how to deal with Gaia astrometry, with recommendations on how best to estimate distances from parallaxes. The Gaia archive features an enhanced visualisation service which can be used for quick initial explorations of the entire Gaia DR2 data set. Pre-computed cross matches between Gaia DR2 and a selected set of large surveys are

    The aim of the present paper is to inform physicians about the work completed by nurses and professors of baccalaureat nurses in the framework of Leonardo da Vinci project, organised and sponsored by the European Union. The goal of the project was to increase the effectiveness of chief nurses throughout their further training programme in the field of management. The team of Szeged chose the human resource management, since in this field is possible to achieve the greatest improvement with the smallest financial investment. We measured the fluctuations and the absentees of the nurses, the changes in the degree of education, the nurse' and patient' satisfaction at the beginning and at the end of the period studied. Except the patient's satisfaction all the other parameters improved by the end of tested period. The project provided a unique possibility to compare the state of the Hungarian nursing with that of the countries belonging to the European Union, to exchange the experience and to learn some new methods. In the framework of this project a book of two volumes was prepared containing the suggestions of EU. This book is widely available in English and in French.

  2. Dr Pugh: a poisoner?

    On 16 February 1845 the Reverend W. H. Browne, rector of St John's Church in Launceston, Van Diemen's Land, wrote in his journal, "My dear Wife died very suddenly almost immediately after and in consequence of taking a preparation of Hyd. Cyan. Acid prepared & supplied by Dr Pugh". This journal entry raises a number of questions. Was Dr Pugh treating a condition which he thought merited that treatment or was it a ghastly mistake? Was Caroline Browne suffering from pulmonary tuberculosis? Was hydrocyanic acid an accepted treatment at that time? Did Mrs Browne take the wrong dose? Was an incorrect concentration of the drug prepared by Dr Pugh? Did he use the wrong pharmacopoeia in preparing the hydrocyanic acid? Why was there no inquest? Only some of these questions can be answered.

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

    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.

    Antonio Luis Ampliato Briones

    2014-10-01

    Full Text Available This paper primarily reflects on the need to create graphical codes for producing images intended to communicate architecture. Each step of the drawing needs to be a deliberate process in which the proposed code highlights the relationship between architectural theory and graphic action. Our aim is not to draw the result of the architectural process but the design structure of the actual process; to draw as we design; to draw as we build. This analysis of the work of the Late Gothic architect Hernan Ruiz the Elder, from Cordoba, addresses two aspects: the historical and architectural investigation, and the graphical project for communication purposes.

    The behaviour of Tillandsia capillaris Ruiz and Pav. f. capillaris, when exposed to atmospheric pollutants, was assessed by measuring chemical parameters indicating foliar damage and the contents of some heavy metals. Samples were transplanted to three sites in the City of Cordoba and were collected back after 15, 30, 60 and 90 days of exposure. At the same time, samples coming from the collection site were analyzed for each of said exposure times. Chlorophylls, hydroperoxy conjugated dienes, water contents, malondialdehyde, sulfur, Cu, Pb, Ni, Co, Mn, Zn and Fe were measured in the samples. A Foliar Damage Index was calculated from some of these parameters. (orig.)

  8. Hacia el pensamiento de Juan Ruiz de Alarcón

    Directory of Open Access Journals (Sweden)

    2002-12-01

    Full Text Available The comedy of characters was born in the hands of Ruiz de Alarcón as he achieved that from his first comedies, those of enredo, the main characters learnt to govern their own actions without any classification. That is the reason why the critics, without any further analysis, have described his theatre as 'moral'. Nevertheless, we are talking about a dramatist who stages mirages, unmasks tyrants disguised as level-headed monarchs, and frustrates the development of those court favourites who were egoists and ill by their passions. At the same time, the omission of providence becomes another kind of protest. All the court on the stage to ridicule with irony and punish their bad habits and delusions. When he finally discovered the politics of the conde-duque de Olivares, he decided to give up theatre. Therefore, we discover another Juan Ruiz de Alarcón never suspected: the dramatist who believed in the program of reformation that the conde-duque de Olivares, court favourite of King Philip IV, wanted to impose to a «patria doliente», name given by the dramatist to the Spain of the first half of the 17th century.La comedia de caracteres nace en manos de Ruiz de Alarcón porque consigue que, a partir de sus primeras comedias, las de enredo, los protagonistas aprendan a regir sus propias acciones al margen de tipificación alguna. Motivo por el que la crítica, sin entrar en más análisis, haya calificado su teatro como 'moral'. Sin embargo, nos encontramos ante un dramaturgo que escenifica espejismos; desenmascara a tiranos disfrazados de monarcas ecuánimes; frustra la trayectoria de privados egoístas y sedientos de poder o enfermos por sus pasiones; mientras que, al mismo tiempo, la omisión de la providencia se convierte, también, en otra clase de protesta. Toda la corte sobre las tablas para, con ironía, ridiculizar y castigar sus vicios y delirios. Cuando por fin descubrió los de la política del conde-duque de Olivares, decidi

  11. Urodynamics in the anatomical work of Leonardo da Vinci (1452-1519).

    Science.gov (United States)

    Schultheiss, D; Grünewald, V; Jonas, U

    1999-06-01

    Leonardo da Vinci (1452-1519) incorporates the symbiosis of art and medicine and can be addressed as the founder of medical illustration in the time of the Renaissance. His anatomy studies were not published in his time, which explains why Leonardo's outstanding knowledge of anatomy, physiology, and medicine had no impact on his scientific contemporaries and is therefore primarily of retrospective importance in the history of medicine. The collection of anatomical illustrations remained unknown until their rediscovery in the eighteenth century and their wide publication at the beginning of our century. This article systematically reviews Leonardo's genitourinary drawings with regard to urodynamic aspects of the upper and lower urinary tract, highlighting topics such as vesicoureteral reflux and urinary sphincter mechanisms.

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

    Science.gov (United States)

    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

  15. Leonardo Da Vinci and stroke - vegetarian diet as a possible cause.

    Science.gov (United States)

    Oztürk, Serefnur; Altieri, Marta; Troisi, Pina

    2010-01-01

    Leonardo da Vinci (April 15, 1452 to May 2, 1519) was an Italian Renaissance architect, musician, anatomist, inventor, engineer, sculptor, geometer, and painter. It has been gleaned from the many available historical documents that da Vinci was a vegetarian who respected and loved animals, and that he suffered from right hemiparesis in the last 5 years of his life. A vegetarian diet has both positive and negative influences on the cerebrovascular system. In this report, a possible relation between a vegetarian diet and stroke is discussed from various perspectives as related to Leonardo da Vinci's stroke. Copyright (c) 2010 S. Karger AG, Basel.

  17. Leonardo-BRDF: A New Generation Satellite Constellation

    Instantaneous net radiation flux at the top of the atmosphere is one of the primary drivers of climate and global change. Since the dawn of the satellite era, great efforts and expense have gone into measuring this flux from single satellites and even (for a several-year period) from a constellation of three satellites called ERBE. However, the reflected solar flux is an angular and spectral integral over the so-called "BRDF" or Bidirectional Reflectance Distribution Function, which is the angular distribution of reflected solar radiation for each solar zenith angle and each wavelength. Previous radiation flux satellites could not measure instantaneous BRDF, so scientists have had to fall back on models or composites. Because their range of observed solar zenith angles was very limited due to sunsynchronous orbits, the resultant flux maps are too inaccurate to see the dynamics of radiation flux or to reliably correlate it with specific phenomena (hurricanes, biomass fires, urban pollution, dust outbreaks, etc.). Accuracy only becomes acceptable after monthly averaging, but this washes out almost all cause-and-effect information, further exacerbated by the lack of spectral resolution. Leonardo-BRDF is a satellite system designed to measure the instantaneous spectral BRDF using a formation of highly coordinated satellites, all pointing at the same Earth targets at the same time. It will allow scientists for the first time to assess the radiative forcing of climate due to specific phenomena, which is bound to be important in the ongoing debate about global warming and what is causing it. The formation is composed of two satellite types having, as instrument payloads, single highly-integrated miniature imaging spectrometers or radiometers. Two nearby "keystone" satellites anchor the formation and fly in static orbits. They employ wide field of view imaging spectrometers that are extremely light and compact. The keystone satellites are identical and can operate in

  20. Leonardo da Vinci's Geology: The Authenticity of The Virgin of the Rocks

    Science.gov (United States)

    Pizzorusso, Ann

    2017-04-01

    Viewed from a geological perspective, all of Leonardo's paintings and drawings reveal a remarkable fidelity to nature. The Virgin of the Rocks in the National Gallery in London (1495-1508), attributed to him, displays no such fidelity. If we compare it to the Virgin of the Rocks in the Louvre in Paris (1483-86) whose geological accuracy is astounding, we cannot help questioning whether Leonardo painted the background in the National Gallery work. Over the centuries, various arguments have called into question the attribution of the National Gallery painting to Leonardo. Scholars have analyzed the brush strokes, undertaken document searches and tried to prove definitively that Leonardo produced the National Gallery version. However, there have always been doubts, naysayers and many unanswered questions concerning its authenticity. The fact that attribution of the work has been the subject of such controversy throughout history suggests that new diagnostic means of determining authenticity is in order. A comparison of the representations of geological formations in the two paintings offers such means. It seems unlikely that the same person could have portrayed rock formations so accurately in the Louvre work and so incongruously in the National Gallery painting.

    What can be learned from historical anatomical drawings and how to incorporate these drawings into anatomical teaching? The drawing "A skull sectioned" (RL 19058v) by Leonardo da Vinci (1452-1519), hides more detailed information than reported earlier. A well-chosen section cut explores sectioned paranasal sinuses and ductus nasolacrimalis. A dissected lateral wall of the maxilla is also present. Furthermore, at the level of the foramen mentale, the drawing displays compact and spongious bony components, together with a cross-section through the foramen mentale and its connection with the canalis mandibulae. Leonardo was the first to describe a correct dental formula (6424) and made efforts to place this formula above the related dental elements. However, taking into account, the morphological features of the individual elements of the maxilla, it can be suggested that Leonardo sketched a "peculiar dental element" on the position of the right maxillary premolar in the dental sketch. The fact that the author did not make any comment on that special element is remarkable. Leonardo could have had sufficient knowledge of the precise morphology of maxillary and mandibular premolars, since the author depicted these elements in the dissected skull. The fact that the author also had access to premolars in situ corroborates our suggestion that "something went wrong" in this part of the drawing. The present study shows that historical anatomical drawings are very useful for interactive learning of detailed anatomy for students in medicine and dentistry.

    To review the accuracy of Leonardo's anatomical studies of the female external genitalia and the foetus, particularly those concerning the umbilical cord with its blood vessels. The anatomical drawings of Leonardo da Vinci which are now stored in the Windors Castle near London were reviewed and the accuracy of the details of the genital apparatus and foetus was evaluated. A written comment characterizes many of his drawings. He described accurately the position of the uterine blood vessels and the relationship between the pelvic organs. However his drawing and description of the female external genitalia and human placenta was incorrect because his understanding of it was inadequate. He believed that the human placenta had cotyledons like that of the ungulate uterus (drown side A of sheet 19). At the top of that sheet some Leonardo's details of the anatomic relationship are shown. In our opinion, Leonardo's misunderstanding is probably because he was only able to perform one anatomical dissection of a pregnant women and foetus and therefore his knowledge was limited. The resulting documentation of the pregnant women and foetus was therefore heavily supplemented with his enormous experience in animal anatomy.

    We present the first Gaia data release, Gaia DR1, consisting of astrometry and photometry for over 1 billion sources brighter than magnitude 20.7 in the white-light photometric band G of Gaia. The Gaia Data Processing and Analysis Consortium (DPAC) processed the raw measurements collected with the Gaia instruments during the first 14 months of the mission, and turned these into an astrometric and photometric catalogue. Gaia DR1 consists of three parts: an astrometric data set which contains the positions, parallaxes, and mean proper motions for about 2 million of the brightest stars in common with the Hipparcos and Tycho-2 catalogues (the primary astrometric data set) and the positions for an additional 1.1 billion sources (the secondary astrometric data set). The primary set forms the realisation of the Tycho-Gaia Astrometric Solution (TGAS). The second part of Gaia DR1 is the photometric data set, which contains the mean G-band magnitudes for all sources. The third part consists of the G-band light curves and the characteristics of 3000 Cepheid and RR Lyrae stars observed at high cadence around the south ecliptic pole. The positions and proper motions in the astrometric data set are given in a reference frame that is aligned with the International Celestial Reference Frame (ICRF) to better than 0.1 mas at epoch J2015.0, and non-rotating with respect to the ICRF to within 0.03 mas yr^-1. For the primary astrometric data set, the typical standard error for the positions and parallaxes is about 0.3 mas, while for the proper motions the typical standard error is about 1 mas yr^-1. Whereas it has been suggested in Gaia Collaboration et al. (2016a) that a systematic component of ∼0.3 mas should be 'added' (in quadrature) to the parallax uncertainties, Brown (2017) clarifies that reported parallax standard errors already include local systematics as a result of the calibration of the TGAS parallax uncertainties by comparison to Hipparcos parallaxes.

    A fluid inclusions study in the Nevado del Ruiz volcano hydrothermal system allowed to characterize fluids involved in the evolution of the geothermal system. Fluid inclusions hosted in quartz, plagioclase and carbonate from samples of the deepest parts of three thermal gradient wells were analyzed to understand fluid-rock interaction. Fluid inclusions hosted in carbonate veins with coloform microestructure represent hydrothermal fluids with temperatures higher than 250 Celsius degrade. This interpretation is supported by microprobe and cathodoluminescence analysis that also indicate a hydrothermal origin for the veins. Fluid inclusions hosted in quartz (mylonite) were originated by metamorphic fluids and fluid inclusions hosted in plagioclase (andesitic lavas) are considered to be originated from magmatic fluids (H 2 O + CO 2 system).

    Full Text Available El cine de Raúl Ruiz nace de una continua reflexión acerca de los modos narrativos cinematográficos. Ruiz configura en Francia un cine exploratorio, experimental y barroco, que indaga en la falta de identidad y la pérdida del territorio. Es en su poética donde logra infiltrar su disidencia, su condición de exiliado metafísico, que encuentra su militancia en la lucha contra el núcleo ideológico de la teoría del conflicto central, que no es sino la operacionalización narrativa de los mecanismos de la competencia, característica del modelo neoliberal. La forma de polisemia visual que Ruiz pone en operación consiste en mirar una película cuya lógica narrativa aparente sigue siempre una misma historia, y cuyos vagabundeos, fallas, recorridos en zig-zag, se explican por su plan secreto, esto es por una película impostora, no explícita, cuyos puntos fuertes se ubican en los momentos débiles de la película aparente, para desde allí narrar otra historia, crear una obra que juegue con la película aparente, que la contradiga y especule sobre ella.The cinema of Raúl Ruiz comes from an ongoing reflection on the narrative modes of cinema.

    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.

  1. Historical continuity in the methodology of modern medical science: Leonardo leads the way.

    Science.gov (United States)

    Pasipoularides, Ares

    2014-02-01

    Early modern medical science did not arise ex nihilo, but was the culmination of a long history stretching back through the Renaissance, the Middle Ages, Byzantium and Roman times, into Greek Antiquity. The long interval between Aristotle and Galen and Harvey and Descartes was punctuated by outstanding visionaries, including Leonardo, the ultimate Renaissance man. His attitude and mindset were based on Aristotelian pursuit of empirical fact and rational thought. He declared himself to be a "man without letters" to underscore his disdain for those whose culture was only mnemonics and philosophical inferences from authoritative books. Leonardo read the Book of Nature with the immense curiosity of the pioneering scientist, ushering in the methodology of modern medical science with help from forerunners. He left no publications, but extensive personal Notebooks: on his scientific research, hydrodynamics, physiological anatomy, etc. Apparently, numerous successors availed themselves of his methodologies and insights, albeit without attribution. In his Notebooks, disordered and fragmentary, Leonardo manifests the exactitude of the engineer and scientist, the spontaneous freshness of one speaking of what he has at heart and that he knows well. His style is unrefined, but intensely personal, rich with emotion and, sometimes, poetic. Leonardo, the visionary anatomist, strived consistently not merely to imitate nature by depicting body structures, but to perceive through analysis and simulations the intimate physiologic processes; i.e., the biomechanics underlying the workings of all bodily organs and components, even the mysterious beating heart. It is fitting to regard him as the first modern medical scientist. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

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

    Science.gov (United States)

    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.

    Full Text Available This paper presents a study of the structural properties obtained from volcanic ash from Nevado del Ruiz located in the Central Range of Andes - Colombia. The volcanic ash samples were subjected to hydration processes and heat treatments in situ during characterization stage material. During the hydration process, which consisted of introducing 2.4875 ± 0.0002g of volcanic ash in 20ml of water for 48 hours, the organic fraction present was removed from the particulate suspension in the aqueous medium. From measurements of X-ray diffraction (XRD, it was observed, that the temperature variations between 323 and 673 K influence the phase formation of zeolite with structures Heulandite -Ca, Stellerita and gmelinite. XRD measurements were performed in vacuum and atmospheric pressure. X'pert Highscore Plus program and simulation Rietveld refinement were used for to obtain the structures of each of the phases. It was found, using the Scherrer equation, that crystallite sizes (Δ (2θ are influenced by changes crystal-chemical caused by hydration, heat treatment and pressure conditions during the characterization. A variation of Δ ( 2θ between 37 and 106.9 nm from XRD measurements was found. It was determined that from 423K in the sample of un-hydrated volcanic ash, the formation of zeolite Stellerita presents with a stable phase up to 673 K.

    The structural geology studies around the Nevado del Ruiz Volcano (NRV), based on aerial photographs and digital terrene models interpretation, in conjunction with analysis of morphological, tectonic features, striated fault planes data and stress field calculation allow to propose a structural scheme that explains the pattern of location of hot springs and fluid released in the western part of the NRV. Structures and kinematics in the region are closely related to the dominant tectonic features of the NVR, nominally longitudinal NE-SW and N-S faults (Palestina, Santa Rosa and San Jeronimo) and a transverse NW-SE to E-W system (Villamaria-Termales,Campoalegrito, San Ramon faults). Quaternary stress tensor was obtained with a WSW-ENE direction of contraction, and dextral strike slip deformation by simple shear along main longitudinal faults, while left lateral displacement is transmitted to most of the NW transverse structures. A WSW-ENE direction of compression was also calculated from striated planes of Cretaceous-Paleocene and older rocks, meaning previous right lateral displacements along longitudinal faults (i.e. Palestina or San Jeronimo).

    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.

    The article focuses on a rare example of a miniature skull of unknown origin. The profoundness of the anatomical details, conjoint with outstanding virtuosity, reminds of Leonardo da Vinci's anatomical skull studies and asks for additional interpretation beside the emblematic "memento mori"-character. Following the miscellaneous topics of his skull studies an anatomical-anthropological interpretation is proposed. For such a project the mergence of anthropology, history of medicine and history of art was mandatory. Concerning some discrepancies within the anatomical realism, the depiction of a pathology is discussed and beyond the visualisation of a historic concept of brain function.

    The impressive development of computed tomography (CT) techniques such as the three dimensional helical CT produces a spatial image of the thoracic skull. At the beginning of the 16th century Leonardo da Vinci drew with great precision the thorax oseum. These drawings show an outstanding similarity with the images obtained by three dimensional helical CT. The cumbersome task of the Renaissance genius is a prime example of the careful study of human anatomy. Modern imaging techniques require perfect anatomic knowledge of the human body in order to generate exact interpretations of images. Leonardo's example is alive for anybody devoted to modern imaging studies.

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

    Soranzo, Alessandro; Newberry, Michelle

    2015-08-01

    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. Copyright © 2015 Elsevier Ltd.

  1. A Preliminary Formation Flying Orbit Dynamics Analysis for Leonardo-BRDF

    2001-01-01

    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.

    Leonardo da Vinci (1452-1519) can be called one of the earliest contributors to the history of anatomy and, by extension, the study of medicine. He may have even overshadowed Andreas Vesalius (1514-1564), the so-called founder of human anatomy, if his works had been published within his lifetime. While some of the best illustrations of their time, with our modern knowledge of anatomy, it is clear that many of da Vinci's depictions of human anatomy are inaccurate. However, he also made significant discoveries in anatomy and remarkable predictions of facts he could not yet discover with the technology available to him. Additionally, da Vinci was largely influenced by Greek anatomists, as indicated from his ideas about anatomical structure. In this historical review, we describe da Vinci's history, influences, and discoveries in anatomical research and his depictions and errors with regards to the musculoskeletal system, cardiovascular system, nervous system, and other organs.

However, the opera was cut at the last minute. This article asserts that such alteration may have been the result of political censorship attempting to counteract the criticism of the Discovery of America contained in the original version.

    2011-05-01

    The smile of the famed portrait 'The Mona Lisa' has perplexed both art historians and researchers for the past 500 years. There has been a multitude of theories expounded to explain the nature of the model's enigmatic smile. The origin of the model's wry smile can be demonstrated through a careful analysis of both documented facts concerning the portrait--some gathered only recently through the use of modern technology--and a knowledge of the clinical presentation of Bell's palsy. Bell's palsy is more prevalent in women who are either pregnant or who have recently given birth. This paper postulates that the smile of the portrait's model was due to Leonardo da Vinci's anatomically precise representation of a new mother affected by Bell's palsy subsequent to her recent pregnancy.

    This issue of Journal of Physics: Condensed Matter has been assembled to recognize the valuable contribution of Dr Trevor J Hicks to the field of neutron scattering and magnetism. Trevor began his study of magnetism as a PhD student at Monash University in Melbourne in the early 1960s, working with Professor Jack Smith. From the very beginning magnetism in alloys, and disordered systems in general, became a key aspect of his career. After a postdoctoral position at Harwell working with Dr Graeme Low Trevor returned to Australia and took up a position with Monash. He soon became a key figure in developing the capability for neutron scattering using the HIFAR reactor at the Australian Atomic Energy Commission, now the Australian Nuclear Science and Technology Organisation, ANSTO. The instrumentation was always developed to further his studies of magnetism. The development of polarization analysis measurements of diffuse magnetic scattering, first using iron filters and then his own design of supermirror benders for beam polarization, took place through the 1970s, 1980s and into the 1990s. Throughout this time, Trevor mentored a series of PhD students and postdoctoral fellows, many of whom have contributed to this issue (and, indeed, guest edited it). As befits a scientist and university academic for whom teaching has always been important, Trevor has not only created a strong body of significant research, he has also made a major contribution to preparing several generations of neutron scattering scientists, and this issue reflects that. When I approached Journal of Physics: Condensed Matter with a proposal for an issue in honour of Trevor, the response was immediate and positive. It is with great pleasure that I present the result of that proposal. The great diversity of the content, all centred on neutron scattering and magnetism, reflects the breadth of Trevor's own career and of the scientists with whom he has interacted. Finally, I would like to make some

    Full Text Available Un hombre bueno, médico, investigador científico, historiador, educador, eticista, poeta. Ciertamente el súmmum del humanismo. Dueño de una excepcional inteligencia y una vasta cultura, Efraím Otero Ruiz fue el hombre de quien uno puede decir con total seguridad que es paradigma de la excelencia humana. De profundas -y muy orgullosas- raíces santandereanas, Efraím estudió siempre con los jesuitas: bachiller del Colegio de San Bartolomé La Merced y médico con grado cum laude de la Universidad Javeriana. Para su formación de posgrado viajó a los Estados Unidos a especializarse en endocrinología y medicina nuclear. Su portentoso talento, su inquietud intelectual y esa permanente búsqueda del saber lo llevó a los mejores centros de la época: el Instituto de Estudios Nucleares de Oak Ridge, Tennessee, por entonces el lugar de concentración de los más grandes físicos; la Universidad de California con su campus en Berkeley; el Presbyterian Hospital de la Universidad de Columbia en Nueva York. Eran centros donde, como él mismo me dijo una vez, "pululaban los premios Nobel". Y fue con ellos, codo a codo, que Efraím maduró el altísimo nivel académico y científico que caracterizó su vida profesional. Elegante y refinado escritor, Otero Ruiz tradujo los poetas ingleses y norteamericanos, y quienes hayan leído tales traducciones, estarán de acuerdo conmigo en que ¡son mejores que los textos originales!

    Highlights: • A systematic approach for energy management of complex structures is proposed. • Technological systems of Leonardo da Vinci Airport of Rome are described. • A multi-year consumption analysis highlights the most energy-consuming sectors. • The “Smart Grid” prototype project inherent to T1 Terminal is presented. • Wind and photovoltaic plants are designed and discussed to test the smart storage. - Abstract: Because of the growing need for efficient energy production systems, energy policies promoted in recent years have also involved complex structures, like airports. This paper proposes the implementation of an energy management system for a very energy-consuming structure, composed of different power plants and many energy consumers: the Leonardo da Vinci International Airport of Rome. In this study, the examination of historical data related to airport electric power, thermal energy and fuel consumption is discussed, starting with the analysis of the production energy plants, mainly based on a combined heat and power system. Furthermore, pioneering solutions are proposed, not only to cover airport energy requirements, but also to test the safety and reliability of innovative load management systems. For this reason, the choice of the Leonardo da Vinci management company, oriented to install a smart storage in order to manage the bidirectional energy flows by consumers and producers, is justified. Such innovative energy procurement systems are examined, with the goal of achieving greater penetration of renewable sources: mini and micro wind power plants and high concentrator photovoltaic plants.

    Full Text Available In historiographic narratives, Early Modern trading networks are claimed to promote endogamic strategies for selecting business agents in distant places, as well as for matrimonial and economic partnerships. Focusing on Simon Ruiz trading and financial company (1558-1597 as a case study, this paper questions this theoretical assumption of Early Modern historiography. Through network analysis, it shows the limited degree to which endogamy based on kinship, confessional compatibility, and on a common geographic provenience functioned as a way to entangle and strengthen trade and finance and as a strategy for network expansion and increasing business profits. The selected data sources for this purpose were the documents produced by Simon Ruiz and his company, namely bills of exchange and commercial correspondence.

    Between 1505 and 1506 Leonardo Da Vinci painted his masterpiece, the Battle of Anghiari, in Palazzo Vecchio's Hall of 500 in Florence. The unfinished mural remained visible until 1563, when architect Giorgio Vasari undertook a renovation of the Hall and all traces of the Battle of Anghiari were lost. However, scholarly interpretation and scientific evidence suggest that the mural could be on the eastern wall, hidden behind a brick wall built in 1563 by Vasari. This paper discusses the possibility of using NNA/APT (Nanosecond Neutron Analysis/Associated Particle Technique) to establish the presence of the masterpiece by identifying behind the Vasari's wall chemical elements from the gesso preparation layer of the mural and possibly from its pigments. This paper reports on the experiments run with a simple NNA/APT system and the Monte Carlo simulations that have been carried out in order to outline the experimental setup of an advanced NNA/APT able to detect and locate the tiny amount of gesso and pigments.

    The present study was conducted to examine whether the thumb rule of Leonardo da Vinci could be an objective method in the determination of the natural and artistic proportions of human face. In this study, a sample of 400 subjects (200 male and 200 female, 22-25 years old) was used. Measurements were made of the length of thumb, the length of ear, the approximate distances between the hair line and the glabella or eyebrows, between the glabella or eyebrows and the tip of the nose and the distance between the nose and the chin, and the distance between the ear and the lateral aspect of the eye. The results obtained in the males and females showed significant (p thumb and the proportions of the face examined in the study. Additionally, the height of the face was found to be almost three times the length of the thumb. However, the measurements obtained from female subjects were on average smaller than those taken from males. The results obtained in this experiment could be of value in understanding of the evaluation of the face for the people working in plastic surgery or art.

  2. From Comparison Between Scientists to Gaining Cultural Scientific Knowledge. Leonardo and Galileo

    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.

    Full Text Available A large and successful exhibition to mark the 500th anniversary of the birth of Leonardo da Vinci was held at the Royal Academy, Burlington House, London, in 1952. It was an important event for the public appreciation of Leonardo’s genius. The proposal for the exhibition had come from the Science Museum, whose staff arranged a ‘scientific section’ of the exhibition, providing and displaying photographs and models. The story of these early models is particularly interesting in the light of the subsequent expansion in the use of mechanical models and animations to interpret and present Leonardo’s work. Questions that surrounded their introduction are accentuated by the ubiquity of models today. Some of the 1952 models will be displayed at the Science Museum in 2016, alongside an exhibition of a large group of ‘historical models’ first displayed in Milan in 1953. The occasion should provoke some thoughtful consideration of the current influence of this tool for research and display.

    In this essay Dr Valter Rukavina (Rijeka 1896-1972), excellent specialist in infectious diseases and professor of the Rijeka University School of Medicine, is presented as successful amateur painter. He had been refining his talent through relentless practice since the school days, complementing it with skills and advice from established painters he associated with. He favoured figurative, realistic and somewhat romantic expression for his themes such as coastal landscapes, marinas, Quarnero sceneries, still life in tempera or oil, and drawings in ink or sepia. Despite partial colour blindness, he successfully used colour. He featured in a number of group exhibitions such as that of amateur painters of Rijeka in 1950, of painters physicians of Yugoslavia (Zagreb, 1956), in the Second International Exhibition of Contemporary Art (Florence, 1964), exhibition of the Rijeka branch of the Croatian Association of Visual Artists (Belgrade, 1966), and the 1969 exhibition in Opatija. His native city hosted two one-man exhibitions, the first retrospective in 1971, while he was still alive, and the second posthumous in 2007, with a good selection of his life's work.

    This paper reports in detail on the image-based modelling and unwrapping approach used to create a two-dimensional projected map of an astonishing ostrich egg globe from AD 1504. This miniature egg globe is not only the oldest extant engraved globe, but it is also the oldest post-Columbian globe of the world and the first ever to depict Newfoundland and many other territories. The intention of digitally recording the surface geometry and colour of this unique artefact was to portray the original layout of the world map used by the Florentine Renaissance artist to make this globe. In addition, it was expected to substantiate iconographical details, which are hard to study at its scale of 1:80,000,000. The ostrich egg globe is the prototype of the Lenox Globe kept at the New York Public Library. The latter is very beneficial to examine how the egg globe looked like before being glued together at its equator. On the other hand, unfolding the map engraved in the ostrich egg halves enables a more detailed study of the remarkable details visible on both globes, since the engravings on the quasi-white egg surface are much easier to discern than those of the highly reflective red copper Lenox Globe. Finally, a detailed study of the unwrapped 3D surface is essential to learn more about the world vision of its creator and the incredible efforts that went into making this globe. Thanks to some particular pictographic details as well as the way in which the engravings are applied (by a left-handed person), the globe artist can be identified as Leonardo da Vinci.

Though not definitely proven to be superior to conventional laparoscopy or traditional open surgery in the setting of a randomised trial, in experienced centres robot-assisted surgery allows for excellent surgical outcomes and is a valuable tool to augment modern surgical practice. Our review highlights the depth of history that underpins the robotic surgical platform we utilise today, whilst also detailing the current place of robot-assisted surgery in urology in 2011. The evolution of robots in general and as platforms to augment surgical practice is an intriguing story that spans cultures, continents and centuries. A timeline from Yan Shi (1023-957 bc), Archytas of Tarentum (400 bc), Aristotle (322 bc), Heron of Alexandria (10-70 ad), Leonardo da Vinci (1495), the Industrial Revolution (1790), 'telepresence' (1950) and to the da Vinci(®) Surgical System (1999), shows the incredible depth of history and development that underpins the modern surgical robot we use to treat our patients. Robot-assisted surgery is now well-established in Urology and although not currently regarded as a 'gold standard' approach for any urological procedure, it is being increasingly used for index operations of the prostate, kidney and bladder. We perceive that robotic evolution will continue infinitely, securing the place of robots in the history of Urological surgery. Herein, we detail the history of robots in general, in surgery and in Urology, highlighting the current place of robot-assisted surgery in radical prostatectomy, partial nephrectomy, pyeloplasty and radical cystectomy. © 2011 THE AUTHORS.

  14. ACTIVITY AND Vp/Vs RATIO OF VOLCANO-TECTONIC SEISMIC SWARM ZONES AT NEVADO DEL RUIZ VOLCANO, COLOMBIA

    Directory of Open Access Journals (Sweden)

    Londoño B. John Makario

    2010-06-01

    Full Text Available An analysis of the seismic activity for volcano-tectonic earthquake (VT swarms zones at Nevado del Ruiz Volcano (NRV was carried out for the interval 1985- 2002, which is the most seismic active period at NRV until now (2010. The swarm-like seismicity of NRV was frequently concentrated in very well defined clusters around the volcano. The seismic swarm zone located at the active crater was the most active during the entire time. The seismic swarm zone located to the west of the volcano suggested some relationship with the volcanic crises. It was active before and after the two eruptions occurred in November 1985 and September 1989. It is believed that this seismic activity may be used as a monitoring tool of volcanic activity. For each seismic swarm zone the Vp/Vs ratio was also calculated by grouping of earthquakes and stations. It was found that each seismic swarm zone had a distinct Vp/Vs ratio with respect to the others, except for the crater and west swarm zones, which had the same value. The average Vp/Vs ratios for the seismic swarm zones located at the active crater and to the west of the volcano are about 6-7% lower than that for the north swarm zone, and about 3% lower than that for the south swarm zone. We suggest that the reduction of the Vp/Vs ratio is due to degassing phenomena inside the central and western earthquake swarm zones, or due to the presence of microcracks inside the volcano. This supposition is in agreement with other studies of geophysics, geochemistry and drilling surveys carried out at NRV.

    2013-03-01

    Full Text Available Aim of study: To identify species of wood samples based on common names and anatomical analyses of their transversal surfaces (without microscopic preparations.Area of study: Spain and South America.Material and Methods: The test was carried out on a batch of 15 lumber samples deposited in the Royal Botanical Garden in Madrid, from the expedition by Ruiz and Pavón (1777-1811. The first stage of the methodology is to search and to make a critical analysis of the databases which list common nomenclature along with scientific nomenclature. A geographic filter was then applied to the information resulting from the samples with a more restricted distribution. Finally an anatomical verification was carried out with a pocket microscope with a magnification of x40, equipped with a 50 micrometers resolution scale.Main results: The identification of the wood based exclusively on the common name is not useful due to the high number of alternative possibilities (14 for “naranjo”, 10 for “ébano”, etc.. The common name of one of the samples (“huachapelí mulato” enabled the geographic origin of the samples to be accurately located to the shipyard area in Guayaquil (Ecuador. Given that Ruiz y Pavón did not travel to Ecuador, the specimens must have been obtained by Tafalla. It was possible to determine correctly 67% of the lumber samples from the batch. In 17% of the cases the methodology did not provide a reliable identification.Research highlights: It was possible to determine correctly 67% of the lumber samples from the batch and their geographic provenance. The identification of the wood based exclusively on the common name is not useful.Key words: historic wood; Ruiz and Pavon’s expedition; wood anatomy; wood identification; wood nomenclature.

    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.

  1. The mother relationship and artistic inhibition in the lives of Leonardo da Vinci and Erik H. Erikson.

    Science.gov (United States)

    Capps, Donald

    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.

    Full Text Available 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.

    rhTRAIL is a therapeutic agent, derived from the TRAIL cytokine, which induces apoptosis in cancer cells by activating the membrane death receptors 4 and 5 (DR4 and DR5). Here, we investigated each receptor's contribution to rhTRAIL sensitivity and rhTRAIL resistance. We assessed whether agonistic DR4 or DR5 antibodies could be used to circumvent rhTRAIL resistance, alone or in combination with various chemotherapies. Our study was performed in an isogenic model comprised of the SW948 human colon carcinoma cell line and its rhTRAIL resistant sub-line SW948-TR. Effects of rhTRAIL and agonistic DR4/DR5 antibodies on cell viability were measured using MTT assays and identification of morphological changes characteristic of apoptosis, after acridine orange staining. Sensitivity to the different death receptor ligands was stimulated using pretreatment with the cytokine IFN-gamma and the proteasome inhibitor MG-132. To investigate the mechanisms underlying the changes in rhTRAIL sensitivity, alterations in expression levels of targets of interest were measured by Western blot analysis. Co-immunoprecipitation was used to determine the composition of the death-inducing signalling complex at the cell membrane. SW948 cells were sensitive to all three of the DR-targeting agents tested, although the agonistic DR5 antibody induced only weak caspase 8 cleavage and limited apoptosis. Surprisingly, agonistic DR4 and DR5 antibodies induced equivalent DISC formation and caspase 8 cleavage at the level of their individual receptors, suggesting impairment of further caspase 8 processing upon DR5 stimulation. SW948-TR cells were cross-resistant to all DR-targeting agents as a result of decreased caspase 8 expression levels. Caspase 8 protein expression was restored by MG-132 and IFN-gamma pretreatment, which also re-established sensitivity to rhTRAIL and agonistic DR4 antibody in SW948-TR. Surprisingly, MG-132 but not IFN-gamma could also increase DR5-mediated apoptosis in SW948

    This paper describes the life and work of Dr. Atanasije Puljo (1878-1944). He was a volunteer in the Balkan wars, an active participant in the First World War; he was the first who noted the importance of team-work of a dentist and a surgeon in the care of jaw and facial injuries. He established primacy in this field, as he came up with this brilliant idea three years before other colleagues. His method of treatment of the upper jaw neglected fractures, called the Balkan method, was recognized worldwide. Dr. Puljo is the pioneer of dental radiology in Serbia, founder of the Odontology Clinic of the Medical Faculty and main supporter of the establishment of the School of Dentistry. Merits of Dr. Atanasije Puljo, medical practitioner with a broad knowledge in different fields, remain within the academic institution that was founded by this pioneer of dentistry in Serbia.

    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.

    At present, the millipede fauna of Myanmar comprises 92 species from 34 genera, 13 families and 8 orders, mostly described in 1889-1896. All literature records are cited with updates on species identities, as well as numerous taxonomic problems which make the number of species and even genera still imprecise. The Myanmar millipede fauna contains 70 endemic and five widespread synanthropic species. One species is found to have erroneously been recorded from Myanmar, and is ejected from the list of Myanmar millipedes also because of its uncertain taxonomic status. A complete bibliography on the millipedes of Myanmar, an updated list of the collecting localities and a map of the journeys of Leonardo Fea, the principal collector of Diplopoda in Burma, are also presented.

    After some initial reluctance, nowadays transition from conventional analogue-to-digital radiographic technique is realized in the vast majority of institutions. The eventual triumph of digital over conventional technique is related to its undoubted advantages with respect to image quality and improved image handling in the context of a picture archiving and communication system. CR represents the older system, which matured over decades and experienced some important recent improvements with respect to dose efficiency and work-flow efficiency that strengthened its position. It represents a very versatile, economically attractive system that is equally suited for integrated systems as well as for cassette-based imaging at the bedside. DR systems offer superb image quality and realistic options for dose reduction based on their high dose efficiency. While for a long time only integrated systems were on the market suited for a large patient throughput, also mobile DR systems became recently available. While for the next years, it is likely that DR and CR systems will coexist, the long term perspective of CR will depend on further innovations with respect to dose efficiency and signal-to-noise characteristics while for DR economical aspects and broader availability of mobile systems will play a role.

  10. "Enxiemplo del león e del mur" of the Libro de buen amor: features of the style of Juan Ruiz from its sources

    Directory of Open Access Journals (Sweden)

    Ismael López Martín

    2017-09-01

    Full Text Available Spanish Medieval literature is very rich in classical sources, and the mastery of this technique is seen more easily in plays as important as the celebrated Libro de buen amor, written by Juan Ruiz, Archpriest of Hita, in the first half of the fourteenth century. This article discusses one of the many “enxiemplos” included in the Libro, which serve to illustrate a moralizing idea; it is the “Enxiemplo del león e del mur”, a text which note, as in similar cases, clear plot concomitants with different fables related to it and which were written by Aesop, Babrius and Gualterius. However, the study of the main differences between the texts will articulate, even better, some defining characteristics of the literary and artistic style of the Spanish medieval writer, such as the amplificatio, the update, the manners and the use of the stylistic devices.

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

    Science.gov (United States)

    Blass, Rachel B

    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.

    2013-05-01

    Aim of study: To identify species of wood samples based on common names and anatomical analyses of their transversal surfaces (without microscopic preparations). Area of study: Spain and South America Material and methods: The test was carried out on a batch of 15 lumber samples deposited in the Royal Botanical Garden in Madrid, from the expedition by Ruiz and Pavon (1777-1811). The first stage of the methodology is to search and to make a critical analysis of the databases which list common nomenclature along with scientific nomenclature. A geographic filter was then applied to the information resulting from the samples with a more restricted distribution. Finally an anatomical verification was carried out with a pocket microscope with a magnification of x40, equipped with a 50 micrometers resolution scale. Main results: The identification of the wood based exclusively on the common name is not useful due to the high number of alternative possibilities (14 for naranjo, 10 for ebano, etc.). The common name of one of the samples (huachapeli mulato) enabled the geographic origin of the samples to be accurately located to the shipyard area in Guayaquil (Ecuador). Given that Ruiz y Pavon did not travel to Ecuador, the specimens must have been obtained by Tafalla. It was possible to determine correctly 67% of the lumber samples from the batch. In 17% of the cases the methodology did not provide a reliable identification. Research highlights: It was possible to determine correctly 67% of the lumber samples from the batch and their geographic provenance. (Author) 11 refs.

    El otro gran pilar de la endocrinología y de la Asociación fue Jaime Cortázar, muerto a comienzos de este mes, el mismo día de Ronald Reagan y casi con los mismos años de ausencia del mundo cognoscitivo que afectaron al presidente norteamericano. Para mi formación Jaime fue más que pilar una brújula y un orientador y un apoyo en esos momentos en que uno se ve forzado a pasar de la adolescencia del pregrado a la madurez de la vida profesional. Mi amistad y mi devoción por él la he dejado consignada en varios de mis libros y en muchos de mis escritos. Mario Sánchez en su prólogo y Alfredo en su libro consagran cómo ellos dos, pero yo diría que sobre todo Jaime, se precuparon por hacer de la diabetes una preocupación nacional y para ello llevarla precozmente a los estrados políticos. Lo mismo que se está haciendo ahora, medio siglo después, pero sin la sencillez y la diafanidad que caracterizaron a nuestros pioneros. Jaime aprovechó su reciente designación como Director del Instituto Nacional de Cancerología, en 1955, para visitar continuamente el Ejecutivo y el Legislativo y hacer conocer el problema y promulgar los decretos que apoyaran el Comité Nacional de Lucha contra la Diabetes, que vió su luz ese año y cuya presidencia ocupó. Su apoyo moral eran la consulta de Endocrinología del Instituto (44.8% de todos los pacientes con alteraciones endocrinas no neoplásicas en los 30 años analizados por Jácome y Mesa en su análisis de dicha consulta, publicado en Medicina el año pasado, fueron diabéticos y la Asociación Colombiana de Diabetes que, como lo dice muy bien el autor, muy pronto acogió a la naciente Sociedad Colombiana de Endocrinología. ¡La presencia estimulante de Jaime vivirá para siempre en el recuerdo de todos sus amigos!...

    Population studies indicate that HLA-DR4 is implicated in the susceptibility of IDD. However, biochemical characterization of the serologically defined DR4 haplotype from normal individuals revealed five DR4 and three DQW3 molecular forms. Hence, in this study, they investigated the heterogeneity of the DR4 haplotype, using B-lymphoblastoid cell lines (B-LCL) generated from patients with IDD and seropositive for DR4. Class II molecules, metabolically labeled with 35 S-methionine, were immunoprecipitated with monoclonal antibodies specific for DR(L243), DQ(N297), DQW3(IVD12) or DR and DQ(SG465) and analyzed by two-dimensional polyacrylamide gel electrophoresis (2D-PAGE). The isoelectrofocusing (IEF) conditions employed in this study allow representation only of the DR4 haplotype from either DR3/4 or DR4/4 cell lines. The analysis of six different DR4 haplotypes from seven IDD patients, revealed the presence of two DR4 β and two DQW3 β chains. Three of the six DR4 β haplotypes analyzed shared the same DR4 β chain and three others shared a different one. Additionally five of the six haplotypes shared a different one. Additionally five of the six haplotypes shared the same DQW3 β chain and only one was carrying a different one. Different combinations of the two DR4 and two DQW3 β chains constitute three distinct patterns of DR4 haplotypes. These results suggest the prevalence of a DQW3 β chain in the small sample of IDD patients studied. Studies of a large number of patients should clarify whether IDD is associated with unique variants of DR4 or DQW3 β chains

    This chapter describes the photometric variability processing of the Gaia DR1 data. Coordination Unit 7 is responsible for the variability analysis of over a billion celestial sources. In particular the definition, design, development, validation and provision of a software package for the data processing of photometrically variable objects. Data Processing Centre Geneva (DPCG) responsibilities cover all issues related to the computational part of the CU7 analysis. These span: hardware provisioning, including selection, deployment and optimisation of suitable hardware, choosing and developing software architecture, defining data and scientific workflows as well as operational activities such as configuration management, data import, time series reconstruction, storage and processing handling, visualisation and data export. CU7/DPCG is also responsible for interaction with other DPCs and CUs, software and programming training for the CU7 members, scientific software quality control and management of software and data lifecycle. Details about the specific data treatment steps of the Gaia DR1 data products are found in Eyer et al. (2017) and are not repeated here. The variability content of the Gaia DR1 focusses on a subsample of Cepheids and RR Lyrae stars around the South ecliptic pole, showcasing the performance of the Gaia photometry with respect to variable objects.

    It is impossible for the Japanese fusion community, in particular for those associated with the ITER Project,to hear about the retirement of Dr. Michel Huguet without a great amount of gratitude, recollections, warm feelings, and the inevitable sadness. He was a first-generation ITER EDA person. Three months after the signing of the ITER EDA Agreement in July 1992, he arrived at the Naka Joint Work Site as Deputy Director of the ITER Central Team and Head of the site and he stayed for more than ten years. The Naka site was for design and technical co-ordination in the areas of magnets, plasma control and heating, plant systems, buildings, etc. Dr. Huguet was considered a highly qualified person to fill the position, since he had been successful as Deputy Director in similar areas in the JET Joint Undertaking. During the ITER EDA he co-ordinated the R and D activities in areas for which the Naka Joint Work Site was responsible. These R and D results permitted the completion of the ITER design in the above areas under his supervision. We thank Dr. Huguet for his achievements and contributions to ITER. He played a crucial role in establishing the convincing scientific and technical basis for ITER implementation. This was only made possible by his broad abilities and his dedication to the cause of fusion in general and ITER in particular

    Between 1505 and 1506 Leonardo Da Vinci painted his masterpiece, the Battle of Anghiari, in Palazzo Vecchio's Hall of 500 in Florence. The unfinished mural remained visible until 1563, when architect Giorgio Vasari undertook a renovation of the Hall and all traces of the Battle of Anghiari were lost. However, scholarly interpretation and scientific evidence suggest that the mural could be on the eastern wall, hidden behind a brick wall built in 1563 by Vasari. This paper discusses the possibility of using NNA/APT (Nanosecond Neutron Analysis/Associated Particle Technique) to establish the presence of the masterpiece by identifying behind the Vasari's wall chemical elements from the gesso preparation layer of the mural and possibly from its pigments. This paper reports on the experiments run with a simple NNA/APT system and the Monte Carlo simulations that have been carried out in order to outline the experimental setup of an advanced NNA/APT able to detect and locate the tiny amount of gesso and pigments.

    Antonio Cassella

    2016-08-01

    Full Text Available The perfect memory that informs our local autistic facet is insufficient to deal with the unforeseen change that challenges our nonlocal artistic facet. The loss of quantum nonlocality leads autistics to fail tests rooted in overcoming the less-than-perfect ambiguity that elicits our creativity. The psychological structure by which perfect memory and less-than-perfect creativity empower each other remains in darkness. This article broaches the hypothesis that Leonardo da Vinci envisioned the union of local perfection and nonlocal less-than-perfection, and that he hid his insight in the Adoration of the Magi. Leonardo’s knowledge - expressed here as the logos heuristic—guides a psychological interpretation of the smile of Mona Lisa; of the four avatars of the Vitruvian Man; of the recognition and location of Leonardo’s unknown painting Natività; of the exact location of his lost work, Battaglia di Anghiari; and of a 39,000-year-old abstract engraving in Gorham’s cave at Gibraltar. Logos can be used to single out local, nonlocal computing, and their alliance in pursuing a humanistic path to progress.

    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.

Eloff, or Fritz as he is popularly referred to. I undertook the task with some trepidation and the only claim to the honour to write this article may be the fact that I have known Professor Eloff since 1949 when I was a green-shanked first year veterinary student at the University of Pretoria where he lectured in zoology to the new students.

    A radioimmunoassay procedure is described by which peripheral blood lymphocytes can be typed for HLA-DR specificities. The major advantages of this method are the following: simple and reproducible procedure, no need for B lymphocyte separation, no need for optimal viability, and no need for preabsorption of antisera with platelets. This method will find an application in the genetic and biochemical analysis of the HLA complex, and in the clinical tests of Ia antigens for diagnostic or prognostic purposes and in retrospective transplant studies

    1986-01-01

    In 12 patients with active ulcerative colitis (UC) the rectal epithelial cells were analyzed for HLA-DR antigens by an immunohistochemical technique. The clinical, rectoscopic, and histologic stages were also determined. The investigations were carried out at the beginning of the study and 2 weeks...... and 3 months later. The rectal epithelial cells were HLA-DR-positive in all patients at the first two examinations. After 3 months five patients had changed to an HLA-DR-negative stage, whereas the other seven patients remained HLA-DR-positive. Closer analyses showed that expression/nonexpression of HLA-DR...... antigens on rectal epithelial cells of patients with UC could not be predicted from the clinical, rectoscopic, or histologic findings. HLA-DR expression is normally restricted to immunocompetent cells. The presence of HLA-DR antigens on epithelial cells may be a consequence of immunological reactions...

    Full Text Available The biography of Joaquín Ruiz-Giménez is a virtual paradigm of two historical phenomena which distinguished the last two decades of the Franco regime and, to a large extent, paved the way for the future democracy: on the one hand, the rift between Catholic and Falangist intellectuals and the regime which they had enthusiastically helped to establish after the civil war; and on the other, the secularization of its political thinking and practice. Ruíz-Giménez, ambassador and minister under Franco, was an exception among the Catholic laity that collaborated with the dictatorship, in that he held high government positions and, despite all the reservations concerning his personal development, for many of his peers as well as many aspiring figures of the coming generations, he symbolized the definitive renunciation of all legitimacy of power based on victory in battle or on Catholic natural law, and the definitive adoption of the language of human rights and democracy. | La biografía de Joaquín Ruiz-Giménez representa casi de manera paradigmática dos fenómenos históricos que caracterizaron las dos últimas décadas del franquismo y sentaron, en buena medida las bases de la futura democracia: por un lado, el alejamiento de los intelectuales católicos y falangistas respecto al régimen que habían contribuido a levantar con entusiasmo tras la guerra civil; por otro, la secularización de su pensamiento y práctica política. Ruiz-Giménez, embajador y ministro de Franco, fue una excepción entre los seglares católicos que colaboraron con la dictadura desempeñando altas responsabilidades de gobierno y, pese a todas las cautelas de su evolución personal, simbolizó para bastantes compañeros de su generación, así como para muchos jóvenes alumnos de las nuevas generaciones, la renuncia definitiva a toda legitimación del poder basada en la victoria de las armas o en el iusnaturalismo católico y la adopción irreversible del lenguaje de

  20. Perturbation and melting of snow and ice by the 13 November 1985 eruption of Nevado del Ruiz, Colombia, and consequent mobilization, flow and deposition of lahars

    1990-01-01

    A complex sequence of pyroclastic flows and surges erupted by Nevado del Ruiz volcano on 13 November 1985 interacted with snow and ice on the summit ice cap to trigger catastrophic lahars (volcanic debris flows), which killed more than 23,000 people living at or beyond the base of the volcano. The rapid transfer of heat from the hot eruptive products to about 10 km2 of the snowpack, combined with seismic shaking, produced large volumes of meltwater that flowed downslope, liquefied some of the new volcanic deposits, and generated avalanches of saturated snow, ice and rock debris within minutes of the 21:08 (local time) eruption. About 2 ?? 107 m3 of water was discharged into the upper reaches of the Molinos, Nereidas, Guali, Azufrado and Lagunillas valleys, where rapid entrainment of valley-fill sediment transformed the dilute flows and avalanches to debris flows. Computed mean velocities of the lahars at peak flow ranged up to 17 m s-1. Flows were rapid in the steep, narrow upper canyons and slowed with distance away from the volcano as flow depth and channel slope diminished. Computed peak discharges ranged up to 48,000 m3 s-1 and were greatest in reaches 10 to 20 km downstream from the summit. A total of about 9 ?? 107 m3 of lahar slurry was transported to depositional areas up to 104 km from the source area. Initial volumes of individual lahars increased up to 4 times with distance away from the summit. The sedimentology and stratigraphy of the lahar deposits provide compelling evidence that: (1) multiple initial meltwater pulses tended to coalesce into single flood waves; (2) lahars remained fully developed debris flows until they reached confluences with major rivers; and (3) debris-flow slurry composition and rheology varied to produce gradationally density-stratified flows. Key lessons and reminders from the 1985 Nevado del Ruiz volcanic eruption are: (1) catastrophic lahars can be generated on ice- and snow-capped volcanoes by relatively small eruptions; (2

    This report describes the work of dismantling and demolishing reactor DR 2, the waste volumes generated, the health physical conditions and the clearance procedures used for removed elements and waste. Since the ultimate goal for the decommissioning project was not clearance of the building, but downgrading the radiological classification of the building with a view to converting it to further nuclear use, this report documents how the lower classification was achieved and the known occurrence of remaining activity. The report emphasises some of the deliberations made and describes the lessons learned through this decommissioning project. The report also intends to contribute towards the technical basis and experience basis for further decommissioning of the nuclear facilities in Denmark. (au)

    2004-01-01

    This interview with Professor Dr. Daniel Spreng of the Center for Energy Policy and Economics (CEPE) in Zuerich, Switzerland, deals with questions concerning research in the area of energy economics. In particular, the situation in Switzerland, where mains-connected sources of energy such as electricity and gas play an important role in energy supply, is looked at in the light of market liberalisation. Various approaches to the liberalisation of gas and electricity systems are discussed and the costs of liberalised supply systems are compared with those of the present monopolistic situation. Also, energy reserves and the use of the gas distribution system in a future hydrogen-based energy supply scenario are looked at. Projects currently being worked on at the CEPE are reviewed

    2018-04-01

    This chapter of the Gaia DR2 documentation describes the models and processing steps used for the astrometric core solution, namely, the Astrometric Global Iterative Solution (AGIS). The inputs to this solution rely heavily on the basic observables (or astrometric elementaries) which have been pre-processed and discussed in Chapter 2, the results of which were published in Fabricius et al. (2016). The models consist of reference systems and time scales; assumed linear stellar motion and relativistic light deflection; in addition to fundamental constants and the transformation of coordinate systems. Higher level inputs such as: planetary and solar system ephemeris; Gaia tracking and orbit information; initial quasar catalogues and BAM data are all needed for the processing described here. The astrometric calibration models are outlined followed by the details processing steps which give AGIS its name. We also present a basic quality assessment and validation of the scientific results (for details, see Lindegren et al. 2018).

    1980-09-01

    A description of the cold neutron source in DR 3 is given. The moderator of the cold neutron source is supercritical hydrogen at about 30degK and 15 bar abs. The necessary cooling capacity is supplied by two Philips Stirling B20 cryogenerators. The hydrogen is circulated between the cryogenerators and the in-pile moderator chamber by small fans. The safety of the facility is based on the use of triple containment preventing contact between hydrogen and air. The triple containment is achieved by enclosing the high vacuum system, surrounging the hydrogen system, in a helium blanket. The achieved spectrum of the thermal neutron flux and the gain factor are given as well as the experience from more than 5 years of operation. Finally some work on extension of the facility to operate two cold sources is reported. (author)

    Project Leonardo represented a feasibility study to evaluate the impact of a disease and care management (D&CM) model and of the introduction of "care manager" nurses, trained in this specialized role, into the primary health care system. Thirty care managers were placed into the offices of 83 general practitioners and family physicians in the Apulia Region of Italy with the purpose of creating a strong cooperative and collaborative "team" consisting of physicians, care managers, specialists, and patients. The central aim of the health team collaboration was to empower 1,160 patients living with cardiovascular disease (CVD), diabetes, heart failure, and/or at risk of cardiovascular disease (CVD risk) to take a more active role in their health. With the support of dedicated software for data collection and care management decision making, Project Leonardo implemented guidelines and recommendations for each condition aimed to improve patient health outcomes and promote appropriate resource utilization. Results show that Leonardo was feasible and highly effective in increasing patient health knowledge, self-management skills, and readiness to make changes in health behaviors. Patient skill-building and ongoing monitoring by the health care team of diagnostic tests and services as well as treatment paths helped promote confidence and enhance safety of chronic patient management at home. Physicians, care managers, and patients showed unanimous agreement regarding the positive impact on patient health and self-management, and attributed the outcomes to the strong "partnership" between the care manager and the patient and the collaboration between the physician and the care manager. Future studies should consider the possibility of incorporating a patient empowerment model which considers the patient as the most important member of the health team and care managers as key health care collaborators able to enhance and support services to patients provided by physicians in

    Full Text Available The maize weevil (Sitophilus zeamais Motschulsky is one of most important pest of stored seeds worldwide, but its current control method is based on the use of synthetic insecticides, usually leading to undesirable problems such as insecticide residues on treated food, human intoxications, and insect resistance development. Therefore the search of friendly alternative methods is required. The aim of this study was to assess, under laboratory conditions, the insecticidal properties of Peumus boldus Molina, Laurelia sempervirens (Ruiz & Pav. Tul., and Laureliopsis philippiana (Looser Schodde essential oils against S. zeamais. The phytochemical analysis of the three essential oils showed 1,8-cineole, safrole and methyleugenol as the common components; all of them documented with insecticidal activity from essential oils from other plant species. The highest toxicity (100% mortality of these three oils acting as a contact insecticide was observed at 24 h exposure at 4% concentration. The estimated LC50 values for P. boldus, L. sempervirens, and L. philippiana were 0.37, 1.02, and 0.28 μL g-1, respectively. Peumus boldus exhibited the highest fumigant activity with 100% adult mortality at 30 μL oil L-1 air. At ≥ 0.5% (v/w concentration, all essential oils showed repellent activity. These three essential oils showed a promissory insecticidal activity against the maize weevil.

    Full Text Available It is a topic to refer Leonardo when we introduce any branch of the art, science o technique because his manuscripts ever contain news that before him never where explored, nor profited even later. This can be understood because these manuscripts never where published till five centuries later. Observations referred to design of structures are the less known and otherwise the less studied. Really the most important problems about this subject are contained in the Codex I of Madrid, some in the Codex Atlantic, and less in the Codex II of Madrid. Other books do not refer these questions. Leonardo, in his drawings, manifested an obsessive search for solutions to the problem of how to span great distances with short pieces. In his notebooks, we find reiterative diagrams which seem to be searching for variants of frames capable of constituting structures, mainly roofs, floors and bridges, which could cover large distances by using manageable pieces that could easily be supplied. In this paper we analyze with actual computer programs how his proposals could be achieved and we establish some conclusions about it.

    Ya resulta tópico referirse a Leonardo cada vez que tocamos algún tema de arte, ciencia o técnica puesto que en sus escritos siempre podemos encontrar aspectos que nadie estudió antes ni, en muchos casos, nadie explotó después. Esto se explica porque sus manuscritos no fueron publicados hasta cinco siglos después. Sus observaciones respecto al diseño de estructuras son menos conocidas y son también las menos estudiadas. Realmente sus principales aportaciones se contienen en el Códice I de Madrid, y menos en el Códice II de Madrid, algunas otras, más generales, en el Códice Atlántico. Sus otros cuadernos de notas no tratan de estas cuestiones. En sus dibujos, Leonardo manifestó una obsesiva búsqueda de soluciones para cubrir grandes luces con piezas cortas.

This article therefore aims at analyzing Hotschnig’s focus on the theme of guilt in his novels. Three examples of Hotschnig’s prose work serve as case studies: his debut Aus, and the two novels Leonardos Hände, and Ludwigs Zimmer. Since guilt seems to be a very important topic in the Austrian literary tradition, this article also tries to establish whether and how Hotschnig takes up this grand Austrian tradition of writing about guilt.

    1990-01-01

    The BIMA array is used to map the 95-GHz 8(0) to 7 1A(+) transition of methanol and the 98-GHz J = 2-1 transition of CS toward the DR 21(OH) and DR 21 star-forming regions. Several strong methanol masers were found. The positions of the two brightest masers were measured with an accuracy of about + or - 0.3 arcsec. Toward DR 21(OH), the positions, velocities, and line shapes of the 95 GHz masers are in excellent agreement with those of the 84-GHz 5(-1) to 4 () methanol masers previously mapped by Batrla and Menten (1988), demonstrating that maser emission in both transitions originates from the same clumps of gas. The methanol masers are offset from CS emission peaks and from other known infrared and maser sources; they may possibly be clustered along the interface between outflows, traced by shock-excited H2 emission, and dense ambient gas, traced by CS emission. 25 refs

    Herbert James Hall, MD (1870-1923), was a pioneer in the systematic and organized study of occupation as therapy for persons with nervous and mental disorders that he called the "work cure." He began his work in 1904 during the early years of the Arts and Crafts Movement in the United States. His primary interest was the disorder neurasthenia, a condition with many symptoms including chronic fatigue, stress, and inability to work or perform everyday tasks. The prevailing treatment of the day was absolute bed rest known as the "rest cure." Hall believed that neurasthenia was not caused by overwork but by faulty living habits that could be corrected through an ordered life schedule and selected occupations. He identified several principles of therapy that are still used today including graded activity and energy conservation. Dr. Adolph Meyer credits Hall for organizing the ideas on the therapeutic use of occupation (Meyer, 1922). Hall also provided the name American Occupational Therapy Association for the professional organization and served as the fourth president. For his many contributions to the profession Hall deserves to be recognized as a major contributor to the development and organization of occupational therapy.

    As the title of my paper indicates, Dr. Rudolph Binion was my professor, mentor, and a leading psychohistorian. My paper in memoriam to Rudolph Binion is intended as both a retrospective and an introspective account of my relationship with him, as he had a pivotal influence on me when he was my professor at Columbia University. His help and influence continued after I left graduate school. In my paper I also deal with the enormous stresses of navigating through graduate school, for those students whose goal was to earn the Ph.D. degree. Some examinations were dreaded, For Example The "Examination in Subjects," popularly called the "Oral Exam." The "incubation" period was long indeed, frequently averaging nearly ten years, and it was an ordeal, as the rate of attrition was very high. There is then also the question of "ego strength" and that of "transference" toward the professor. Graduate school is indeed a long and strenuous challenge. I took a seminar in modern French history, a requirement for the Master's degree with Professor Binion, which was consequential for me, as he taught me to be objective in writing history. Professor Binion was a demanding and outstanding teacher.

    We present a new catalog of spectroscopically confirmed white dwarf stars from the Sloan Digital Sky Survey (SDSS) Data Release 7 spectroscopic catalog. We find 20,407 white dwarf spectra, representing 19,712 stars, and provide atmospheric model fits to 14,120 DA and 1011 DB white dwarf spectra from 12,843 and 923 stars, respectively. These numbers represent more than a factor of two increase in the total number of white dwarf stars from the previous SDSS white dwarf catalogs based on DR4 data. Our distribution of subtypes varies from previous catalogs due to our more conservative, manual classifications of each star in our catalog, supplementing our automatic fits. In particular, we find a large number of magnetic white dwarf stars whose small Zeeman splittings mimic increased Stark broadening that would otherwise result in an overestimated log g if fit as a non-magnetic white dwarf. We calculate mean DA and DB masses for our clean, non-magnetic sample and find the DB mean mass is statistically larger than that for the DAs.

    Full Text Available The paintings of Caravaggio’s and Leonardo da Vinci’s The Last Supper are two iconic artworks from two maestros in a different era. Caravaggio is one of the fame Baroque’s artists and da Vinci is the most famous Renaissance man, who created the same theme of a painting, The Last Supper. The theme represents the story of Christ’s supper. Through an inductive view, this comparative study analyzes the aesthetic structures of both paintings, by using Feldman’s perspective in Art as Image and Idea (1967. The analysis includes visual structures, including line, form, darkness-lightness; elements of the organization, including unity, balance, rhythm, and proportion; and elements of perception and aesthetic, inclu- ding empathy and a psychic distance. The result of this research discovers two different perspectives of aesthetic characteristics of Baroque and Renaissance paintings.   Keywords: baroque, Caravaggio, Leonardo da Vinci, renaissance, the last supper

    Full Text Available El concepto de Estado-Nación, construcción legitimada en las comunidades imaginadas de Benedict Anderson, ha sido ampliamente discutido en los últimos años. La obra de Leonardo Padura configura, en este sentido, nuevos procesos de resignificación cultural y política que rompen con la idea de unidad y homogeneidad de la identidad nacional. La cola de la serpiente agudiza esta ruptura con la introducción de la comunidad china en la Habana. El barrio chino será la metáfora de la pertenencia a la nación en cuanto sus espacios destruidos aterrizan los grandes “valores nacionales” a la inmediatez de la violencia y la necesidad. The concept of Nation-state, a construction legitimated in the approaches of imagined communities of Benedict Anderson, has been widely discussed in recent years. The work of Leonardo Padura configured, in this way, new processes of cultural and political redefinition which break with the idea of unity and homogeneity of national identity. La cola de la serpiente exacerbated this rupture with the introduction of the Chinese community in Havana. Chinatown is the metaphor of belonging to the nation as its destroyed spaces land the great “national values” to the immediacy of violence and necessity.

    1985-01-01

    Seventy-four American white thyroid cancer patients were typed for HLA-A, B, and DR antigens. A significant increase in HLA-DR7 was found in the nonradiation-associated thyroid cancer patients (42.5%, 20/47 cases), compared to 22.8% of 979 normal controls. The association is stronger in the follicular and mixed papillary-follicular subgroup (52.0%, 13/25 cases, P corrected less than 0.01). The occurrence of various malignancies in family members was found in 57.9% of HLA-DR7 positive patients, versus 20% of HLA-DR7 negative patients, in a retrospective record review. Although the frequency of HLA-DR7 was not increased in the radiation-associated thyroid cancer patients (22.2%, 6/27 cases), the interval from the irradiation date to the onset date of thyroid cancer was shorter in HLA-DR7 positive cases (17.3 +/- 6.2 years) than in HLA-DR7 negative patients (29.4 +/- 11.5 years). This data suggest that HLA-DR7 is associated with and may influence development of thyroid cancer

  10. Vapour discharges on Nevado del Ruiz during the recent activity: Clues on the composition of the deep hydrothermal system and its effects on thermal springs

    The Nevado del Ruiz volcano is considered one of the most active volcanoes in Colombia, which can potentially threaten approximately 600,000 inhabitants. The existence of a glacier and several streams channelling in some main rivers, flowing downslope, increases the risk for the population living on the flank of the volcano in case of unrest, because of the generation of lahars and mudflows. Indeed, during the November 1985 subplinian eruption, a lahar generated by the sudden melting of the glacier killed twenty thousand people in the town of Armero. Moreover, the involvement of the local hydrothermal system has produced in the past phreatic and phreatomagmatic activity, as occurred in 1989. Therefore, the physico-chemical conditions of the hydrothermal system as well as its contribution to the shallow thermal groundwater and freshwater in terms of enthalpy and chemicals require a close monitoring. The phase of unrest occurred since 2010 and culminated with an eruption in 2012, after several years of relative stability, still maintains a moderate alert, as required by the high seismicity and SO2 degassing. In October 2013, a sampling campaign has been performed on thermal springs and stream water, located at 2600-5000 m of elevation on the slope of Nevado del Ruiz, analyzed for water chemistry and stable isotopes. Some of these waters are typically steam-heated (low pH and high sulfate content) by the vapour probably separating from a zoned hydrothermal system. By applying a model of steam-heating, based on mass and enthalpy balances, we have estimated the mass rate of hydrothermal steam discharging in the different springs. The composition of the hottest thermal spring (Botero Londono) is probably representative of a marginal part of the hydrothermal system, having a temperature of 250 °C and low salinity (Cl 1500 mg/l), which suggest, along with the retrieved isotope composition, a chiefly meteoric origin. The vapour discharged at the steam vent "Nereidas" (3600

    This work presents an estimation of the geothermal potential of the Nevado del Ruiz (NDR) volcano, bridging the knowledge gap to develop geothermal energy in Colombia and improve resource estimates in South America. Field work, laboratory measurements, geological interpretations, 2D numerical modeling, and uncertainty analysis were conducted to the northwest of the NDR to assess temperature at depth and define thermal energy content. About 60 rock samples were collected at outcrops to measure thermal conductivity with a needle probe. A 2D numerical model, built from an inferred geological cross-section, was developed with the software OpenGeoSys to simulate the underground temperature distribution and then estimate the geothermal potential of a 1 km2 area with sufficient temperature, assuming a recovery factor equal to 2.4% and a 30 years exploitation time. Coupled groundwater flow and heat transfer were simulated in steady-state considering two different thermal conductivity scenarios. Results show that the average estimated potential is 1.5 × 10-2 MWt m-1 of the reservoir thickness, considering temperatures greater than 150 °C located at a depth of approximately 2 km, in a selected area situated outside of the Los Nevados National Natural Park (NNP), to avoid any direct intervention on this protected area. According to a Monte Carlo analysis considering pessimist and optimist scenarios of thermal conductivity, the estimated geothermal power was 1.54 × 10-2 MW m-1 (σ = 2.91 × 10-3 MW m-1) and 1.88 × 10-2 MW/m (σ = 2.91 × 10-3 MW m-1) for the two modeling scenario considered.

    Sirih merah leaves Piper crocatum Ruiz & Pav. is a plant that contains flavonoids, tannins, volatile oil and empirically has been used as traditional medicine. This research aimed to study the effect of gamma irradiation on the cytotoxicity activity of sirih merah leaves against L1210 leukemia cells and their chromatograms profile, respectively. Dried sirih merah leaves (water content 8.03%) were irradiated with doses of 5, 7.5, 10 and 15 kGy using a cobalt-60 source. Then the samples were macerated in three kinds of solvent gradually, namely n-hexane, ethyl acetate, and ethanol, thus obtained three kinds of extracts. Cytotoxicity activity test were performed against L1210 leukemia cells by the direct method using trypan blue staining. The most active extracts inhibited the growth of leukemia L1210 cells was ethanol extract (IC 50 of 4.12 μg/ml), then fractionated by column chromatography, obtained 7 fractions. Fraction 2 was the most active fraction inhibited L210 leukemia cells with IC 50 value 13.12 μg/ml. Cytotoxic activity of fraction 2 of sirih merah leaves up to 7.5 kGy did not change significantly compared with the unirradiated sample, but at doses ≥ 10 kGy cytotoxic activity of fraction 2 were significantly decreased. TLC chromatogram of fraction 2 unirradiated and irradiated to a dose of 7.5 kGy were not seen any change, but the TLC-densitometric and GC-MS spectrum indicated changes. Based on the results of the cytotoxic activity of fraction 2 against L1210 leukemia cells and concluded that the TLC profiles of 7.5 kGy dose is the maximum dose for irradiation of sirih merah leaves without changing their bioactivity.

Argumenta que sus documentales, películas etnográficas y noticieros para el cine constituyen una totalidad discursiva que presenta estéticamente la producción del espacio estatal boliviano durante el siglo XX. A partir de una retórica audiovisual que juega con nociones de verticalidad, horizontalidad y centralidad, la obra de Ruiz posiciona el espacio andino como el eje de la modernización estatal y sitúa  a la cuenca amazónica en los márgenes del estado. Concluye que hacer visible la región amazónica en el discurso de la nación tuvo como efecto el desplazamiento de los antagonismos de clase en favor del conflicto entre centro y regiones.This article studies the cinematography of Jorge Ruiz making use of the socio-spatial theory of Henri Lefebvre. It argues that his documentaries, ethnographic films and newsreels for the cinema constitute a discursive totality that presents aesthetically the production of the Bolivian state space during the twentieth century. From an audiovisual rhetoric that plays with notions of verticality, horizontality and centrality, Ruiz’s work locates Andean space as the focal point of state modernization and situates the Amazon basin at the margins of the state. It concludes that in making the Amazon region visible in the nation’s discourse this had the effect of displacing class antagonisms in favor of the conflict between center and regions.

    With the celebration of the centenary of the birth of Dr. Luis Cifuentes Delatte, due to his great scientific personality, we want to emphasize two features that, taken from his works and memories, we consider have not been emphasized enough: his role as historian of urology, both for the histories he narrated of his life experiences and the historical exposition of several pathologies, and also his teaching as professor of several generations of urologists, with the objective of trying to get to know his great human quality as he demonstrated over his life and showed in his writings. We review his books and works, lectures and published papers, in addition the news about his person we have collected from the media, and after analysis, mainly of his memories, we extract data reflecting his personality, and they way he thought and behaved. Since he was young he went with his father to the international urology meetings where he met a great number of personalities in the World of Urology; he extended his training with them, and later on they got to have a great relationship. He travelled around Europe and United States before and after Second World War, respectively, with stays in the most prestigious centers, which he described meticulously. He also reported his activity during the first two years he directed the Department of Urology at the Hospital La Princesa in Madrid and cited the series of collaborators he had. In his research works he made an ample description of historical development as introduction to the various pathologies he analyzed in depth. The reading of the narration of his trips, that he did in the convulse International time he lived, offers details which enable us to know firsthand the situation of urology and the human side of the actors he had relation with, and the social life they had, in addition to data about their families and daily life. As a researcher in transcendental chapters in urological pathology we emphasize his historical

(The 105-DR defense reactor was shut down in 1964.) LSFF was used to investigate fire and safety aspects of large sodium or other metal alkali fires in the LMFBR facilities; it was also used to store and treat alkali metal waste. This closure plan presents a description of the unit, the history of the waste managed, and the procedures that will be followed to close the LSFF as an Alkali Metal Treatment Facility. No future use of LSFF is expected. It is located within the 100-DR-2 (source) and 100-HR-3 (groundwater) operable units, which will be addressed through the RCRA facility investigation/corrective measures study process

    Optical coherence tomography (OCT) was used for non-invasive examination of a well-known, yet complex, painting from the studio of Leonardo da Vinci in combination with routine imaging in various bands of electromagnetic radiation. In contrast with these techniques, OCT provides depth-resolved information. Three post-processing modalities were explored: cross-sectional views, maps of scattering from given depths, and their 3D models. Some hidden alterations of the painting owing to past restorations were traced: retouching and overpainting with their positioning within varnish layers as well as indications of a former transfer to canvas. © 2018 Wiley-VCH Verlag GmbH & Co.

    The Nevado del ruiz volcano (NdR, 5321m asl), one of the most active in Colombia, threatens about 600,000 people. The existence of an ice cap and several streams channeling in some main rivers increase the risk of lahars and mudflows in case of unrest, as occurred during the November 1985 eruption, which caused 20,000 casualties. The involvement of the local hydrothermal system has also produced in the past phreatic and phreatomagmatic activity, as in 1985 and 1989. After more than 7 years of relative stability, since 2010, the still ongoing phase of unrest has produced two small eruption in 2012, and still maintains in high levels of seismicity and SO2 degassing. In October 2013, a sampling campaign has been performed on thermal springs and streamwater, located at 2600-5000 m asl, analyzed for water chemistry and stable isotopes. By applying a model of steam-heating, based on mass and enthalpy balances, we have estimated the mass rate of steam discharging in the different steam-heated springs. The composition of the hottest thermal spring (Botero Londoño) is probably representative of a marginal part of the hydrothermal system, having a temperature of 250°C and low salinity (Cl ~1500 mg/l), which suggest a chiefly meteoric origin, as also confirmed by the isotope composition retrieved for the hydrothermal water. The vapour discharged at the steam vent "Nereidas" (3600 m asl) is hypothesised to be separated from a high-temperature hyrothermal system. Based on its composition and on literature data on fluid inclusions, we have retrieved the P-T-X conditions of the deep hydrothermal system, as well as its pH and fO2. The vapour feeding Nereidas would separate from a byphasic hydrothermal system characterised by the follow parameters: t= 315°C, P=19 MPa, NaCl= 15 %, CO2 = 9%, and similar proportion between liquid and vapour. Considering also the equilibria involving S-bearing gases and HCl, we obtain pH=2, fO2 fixed by FeO-Fe2O3 buffer, and [Cl]=12000 mg/l. Changes

    Female and male adolescents in Germany are increasingly using the Internet to find information about sexuality and sexual health. This review paper summarizes what we know about the status quo of online sexuality education in Germany.Based on a systematic literature review including 40 papers from international, peer-reviewed journals spanning 2010-2017, this paper first describes different aspects of the sexuality-related online search behavior of adolescents: its prevalence, predictors, topics and contexts. One main finding is the fact that adolescents use a computer or smartphone to type their sexuality-related questions into the search engine Google or the search engine of the video platform YouTube.Based on 54 online searches, this paper subsequently presents the kind of sexuality-related online content adolescents find if they ask "Dr. Google" for sexual advice; a collection of 1236 authentic sexuality-related questions of adolescents was used for this analysis. It turned out that online sexuality education offered by leading professional organizations like the BZgA ("Bundeszentrale für gesundheitliche Aufklärung") or pro familia was nearly invisible, while numerous other providers of online sex education consistently appeared in the top Google search results. Among them were the "Dr. Sommer" team of the youth magazine Bravo; online healthcare and advice portals; online forums; the online encyclopedia Wikipedia and, above all, sex education channels on YouTube. In this paper, the latter are presented in more detail for the first time.The third part of the paper addresses the quality of online sexual education over four main areas of quality evaluation. The presentation of the status quo ends with some recommendations both for future research and for sexuality education in practice.

    An autopsy was an important event in 17th century Holland. Autopsies were held in an 'anatomy theater' and performed according to a fixed protocol that often took up to 3 days to complete. Of the five group portraits painted by Rembrandt over the course of his career, two were anatomy lessons given by Dr. Tulp and Dr. Deyman. An examination of Rembrandt's painting Dr. Tulp's Anatomy Lesson (1632) and an X-ray image of the painting, as compared to other paintings of anatomy lessons from the same period, reveal interesting differences, such as positioning, and light and shadow. Not only was the autopsy not performed according to the usual protocol, but in this painting Rembrandt created a unique dramatic scene in his effort to tell a story. We suggest that Dr. Tulp and Rembrandt "modified" the painting of Dr. Tulp's anatomy lesson to emphasize Dr. Tulp's position as the greatest anatomist of his era--"Vesalius of Amsterdam," and as a way of demonstrating God's greatness by highlighting the hand as a symbol of the most glorious of God's creations.

    Full Text Available The Judgment of the Court of Justice of March 8th, 2011 (C-34/09 case Ruiz Zambrano against l'Office National de l'Emploi (ONEM of Belgium highlights an issue, already debated by the jurisprudence and the doctrine, concerning the right of residence of nationals of a third country who are the parents of a children national of a Member State. The approach taken in this case by the ECJ is novel in part due to the own approach to the questions and especially by the arguments around the status of citizen of the EU and the notion of citizenship itself. The key issue of the suit seeks to ascertain the impact of the European Union nationality of some underage children, who have not exercised their right of free movement, on the residency status (irregular of the parents who are nationals of a third country. If until now the premise that "it would be necessary to cross the border" to be covered by Community law was true, the sentence Ruiz Zambrano comes to question this premise to cover a “purely domestic” situation under the protective umbrella of the citizenship status and therefore extending the scope of application of Community law. This Judgment implies a review of one of the favorite topics for scholars -the notion of citizenship- to, from a different perspective, think about the impact of the status of citizen of the Union in the scope of application of Community law.

    TV series such as "House MD", "Grey´s Anatomy" or "Emergency Room" are well perceived by medical students. Seminars featuring medical TV series such as "House MD" might serve as door-opener to attract medical students to learn more about rare diseases. The TV series "House MD" is troublesome for the main character Dr. House is an excellent diagnostician but at the same time a rather misanthropic person. Therefore, lecturing medicine with the help of "House MD" requires constant evaluation. From 2008 to 2016 we are using the well-known TV series "House MD" continuously to attract medical students and teach them about rare diseases as well as diagnostic strategies. We collected from 213 students a detailed questionnaire assessing their learning experience. 76.6% of our students (n = 157) reported to watching medical dramas on a regular basis. The Dr. House seminar was compared to traditional seminars and our students reported an improved learning effect (69.9%), better concentration (89.7%), higher motivation to participate (88.7%), and more fun (86.7%) (all pHouse's behavior quite critically. Likert assessment on a 5-point scale identified strong disagreement with Dr. House´s interpersonal skills in dealing with his colleagues (median = 1) and patients (median = 1). At the same time, the students strongly agreed with his outstanding diagnostic (median = 5) and therapeutic capabilities (median = 4). Medical students visiting a Dr. House teaching seminar are highly motivated to learn more about rare diseases. They were positively influenced by TV series such as Dr. House to improve their diagnostic and clinical skills. At the same time, they are critical enough not to see Dr. House as a role model for their own personality. Well performed medical TV shows such as Dr. House can successfully be used in an educational setting to motivate medical students to come into seminars to learn more about rare diseases.

    Aims: The first Gaia data release (Gaia DR1) provides 2191 ICRF2 sources with their positions in the auxiliary quasar solution and five astrometric parameters - positions, parallaxes, and proper motions - for stars in common between the Tycho-2 catalogue and Gaia in the joint Tycho-Gaia astrometric solution (TGAS). We aim to analyze the overall properties of Gaia DR1 reference frame. Methods: We compare quasar positions of the auxiliary quasar solution with ICRF2 sources using different samples and evaluate the influence on the Gaia DR1 reference frame owing to the Galactic aberration effect over the J2000.0-J2015.0 period. Then we estimate the global rotation between TGAS with Tycho-2 proper motion systems to investigate the property of the Gaia DR1 reference frame. Finally, the Galactic kinematics analysis using the K-M giant proper motions is performed to understand the property of Gaia DR1 reference frame. Results: The positional comparison between the auxiliary quasar solution and ICRF2 shows negligible orientation and validates the declination bias of -0.1mas in Gaia quasar positions with respect to ICRF2. Galactic aberration effect is thought to cause an offset 0.01mas of the Z axis direction of Gaia DR1 reference frame. The global rotation between TGAS and Tycho-2 proper motion systems, obtained by different samples, shows a much smaller value than the claimed value 0.24mas yr-1. For the Galactic kinematics analysis of the TGAS K-M giants, we find possible non-zero Galactic rotation components beyond the classical Oort constants: the rigid part ωYG = -0.38±0.15mas yr-1 and the differential part ω^primeYG = -0.29±0.19mas yr-1 around the YG axis of Galactic coordinates, which indicates possible residual rotation in Gaia DR1 reference frame or problems in the current Galactic kinematical model. Conclusions: The Gaia DR1 reference frame is well aligned to ICRF2, and the possible influence of the Galactic aberration effect should be taken into consideration

    Full Text Available Previous studies have provided valuable insights into the impact of culture on the concept of leadership communication. However, only a few studies that focused on exploring and understanding the values of Confucianism and its impact on the Chinese culture, especially in Malaysia. Thus, this study is among the first study to examine the leadership communication from the perspective of Confucianism towards the leadership of Dr. Mahathir from the perspective of the Chinese community in Malaysia. This study aims to assess the role of Confucian values in Dr. Mahathir’s leadership communication. This study interviewed 15 Chinese leaders. The findings reveal that three main Confucian values are relevant to Dr. Mahathir’s leadership communication. The Confucian values are Zhi (wisdom, Xin (trust and Xiao (filial piety. This study provides a new perspective on leadership communication from the context of cultural diversity in Malaysia which emphasizes on Confucian values.

    Objective: To determine frequencies of HLA DR beta 1 alleles in rheumatoid arthritis in Pakistani patients. Study Design: Cross sectional / analytical study. Place and Duration of Study: Department of Immunology, Armed Forces Institute of Pathology, Rawalpindi in collaboration with Rheumatology departments of Military Hospital, Rawalpindi and Fauji Foundation Hospital, Rawalpindi, from January 2009 to January 2010. Methodology: HLA DR beta 1 genotyping of one hundred Pakistani patients, diagnosed as having RA as per American College of Rheumatology revised criteria 1987, was done. HLA DR beta 1 genotyping was carried out at allele group level (DR beta 1*01-DR beta 1*16) by sequence specific primers in RA patients. Comparison of HLA DR beta 1 allele frequencies between patients and control groups was made using Pearson's chi-square test to find possible association of HLA DR?1 alleles with RA in Pakistani rheumatoid patients. Results: HLA DR beta 1*04 was expressed with significantly increased frequency in patients with rheumatoid arthritis (p <0.05). HLA DR?1*11 was expressed statistically significantly more in control group as compared to rheumatoid patients indicating a possible protective effect. There was no statistically significant difference observed in frequencies of HLA DR beta 1 allele *01, DR beta 1 allele *03, DR beta 1 allele *07, DR beta 1 allele *08, DR beta 1 allele *09, DR beta 1 allele *10, DR beta 1 allele *12, DR beta 1 allele *13, DR beta 1 allele *14, DR?1 allele *15 and DR beta 1 allele *16 between patients and control groups. Conclusion: The identification of susceptible HLA DR beta 1 alleles in Pakistani RA patients may help physicians to make early decisions regarding initiation of early intensive therapy with disease modifying anti rheumatic medicines and biological agents decreasing disability in RA patients.

    Dr. William O. Coffee was an ophthalmologist who conducted an office and mail-order practice in the Midwest from the 1880s until 1927. His main stock in trade was a self-discovered absorption cure for a variety of ocular diseases, with particular emphasis on the medical cure of cataracts. Dr. Coffee's career was a checkered one, marked by dubious credentials, exuberant self-promotion, unlikely and exaggerated claims of medical successes, plagiarism, and rejection by the medical "establishment." Certain parallels may be drawn between his activities and some currently observed practices in ophthalmology.

En la primera parte se revisa la concepción de igualdad política a partir de la obra de Robert Dahl, cuya definición mínima de democracia es adoptada por Morlino. En la segunda, se analiza el valor de la igualdad desde la perspectiva del autor italiano y se argumenta que en la evaluación de un régimen la importancia de esta como valor sustantivo no es clara en términos analíticos, debido a que se traslapa con otras dimensiones de la calidad: las procedimentales y las relativas a resultados.

    Comprehensive studies of the biodiversity of the microbial epilithic community on monuments may provide critical insights for clarifying factors involved in the colonization processes. We carried out a high-throughput investigation of the communities colonizing the medieval church of San Leonardo di Siponto (Italy) by Illumina-based deep sequencing. The metagenomic analysis of sequences revealed the presence of Archaea, Bacteria, and Eukarya. Bacteria were Actinobacteria, Proteobacteria, Bacteroidetes, Cyanobacteria, Chloroflexi, Firmicutes and Candidatus Saccharibacteria. The predominant phylum was Actinobacteria, with the orders Actynomycetales and Rubrobacteriales, represented by the genera Pseudokineococcus, Sporichthya, Blastococcus, Arthrobacter, Geodermatophilus, Friedmanniella, Modestobacter, and Rubrobacter, respectively. Cyanobacteria sequences showing strong similarity with an uncultured bacterium sequence were identified. The presence of the green algae Oocystaceae and Trebuxiaceae was revealed. The microbial diversity was explored at qualitative and quantitative levels, evaluating the richness (the number of operational taxonomic units (OTUs)) and the abundance of reads associated with each OTU. The rarefaction curves approached saturation, suggesting that the majority of OTUs were recovered. The results highlighted a structured community, showing low diversity, made up of extremophile organisms adapted to desiccation and UV radiation. Notably, the microbiome appeared to be composed not only of microorganisms possibly involved in biodeterioration but also of carbonatogenic bacteria, such as those belonging to the genus Arthrobacter, which could be useful in bioconservation. Our investigation demonstrated that molecular tools, and in particular the easy-to-run next-generation sequencing, are powerful to perform a microbiological diagnosis in order to plan restoration and protection strategies.

  14. The left ventricle as a mechanical engine: from Leonardo da Vinci to the echocardiographic assessment of peak power output-to-left ventricular mass.

    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.

    Escrito en una prosa amena y armoniosa, su lectura es verdadero deleite intelectual para quien sigue la apasionante madeja que constituye toda la trama inicial y que envuelve la concepción, el nacimiento y el desarrollo de una institución para el tratamiento del cáncer en Colombia.

    Es apasionante la forma como Efraim toma el hilo de la historia desde sus primeras y más importantes incepciones.

    Es sin duda Claudio Regaud, Jefe del Laboratorio de Radiofisiología del Instituto de Radium de París, la figura clave en la iniciativa de creación de un Instituto de Radium en Colombia. Alfonso Esguerra Gómez, becario de la Institución adquiere una valiosa experiencia en el tratamiento de tumores superficiales de cara y cuello y descubre la famosa pasta Colombia que permite amoldarse sobre la piel mientras en su interior se colocan las agujas de radium.

    En la década de los veinte Regaud se convierte en la figura más prestante en el mundo en el manejo del radium y es invitado universalmente para comunicar no solo sus experiencias sino como consejero y orientador de la creación de institutos de radium en el mundo.

    La invitación a Regaud en 1928 para visitar el Perú es conocida por Alfonso Esguerra y allí por primera vez se organiza un movimiento de influencias que con agudo análisis describe Efraim Otero, para movilizar todas las fuerzas académicas y políticas con el fin de aprovechar esta oportunidad y obtener la visita de Regaud a Colombia.

    En varias ocasiones en el futuro, circunstancias similares harán necesaria la influencia de médicos, no solo eminentes sino dotados de excelentes conexiones sociales y políticas para crear el Instituto Nacional de Radium.

    The red light from the Light Emitting Diode (LED) probe shines through the fingers of Dr. Harry Whelan, a pediatric neurologist at the Children's Hospital of Wisconsin in Milwaukee. Dr. Whelan uses the long waves of light from the LED surgical probe to activate special drugs that kill brain tumors. Laser light previously has been used for this type of surgery, but the LED light illuminates through all nearby tissues, reaching parts of tumors that shorter wavelengths of laser light carnot. The new probe is safer because the longer wavelengths of light are cooler than the shorter wavelengths of laser light, making the LED less likely to injure normal brain tissue near the tumor. Also, it can be used for hours at a time while still remaining cool to the touch. The probe was developed for photodynamic cancer therapy under a NASA Small Business Innovative Research Program grant. The program is part of NASA's Technology Transfer Department at the Marshall Space Flight Center.

    About 60 years have passed since David Bates in a 1950 Physical Review Letter to the Editor first clarified the dissociative recombination mechanism (DR) of molecular ions and provided the conceptual basis for the process that plays an important role in the ionospheres of Earth and other planets, the interstellar medium, and electrical discharges. His visionary (and characteristically 'terse') thumbnail sketch of the DR mechanism only hinted at the subtleties that have kept atomic theorists and experimentalists busy for many years. In my talk, I will focus on experiments on N 2 + recombination, beginning with plasma afterglows, and then move on to the 'after'-afterglow period that is now dominated by the powerful storage-ring methods.

The 105-DR Large Sodium Fire Facility (LSFF), which was in operation from about 1972 to 1986, was a research laboratory that occupied the former ventilation supply room on the southwest side of the 105-DR Reactor facility. The LSFF was established to provide a means of investigating fire and safety aspects associated with large sodium or other metal alkali fires in the liquid metal fast breeder reactor (LMFBR) facilities. The 105-DR Reactor facility was designed and built in the 1950's and is located in the 100-D Area of the Hanford Site. The building housed the 105-DR defense reactor, which was shut down in 1964. The LSFF was initially used only for engineering-scale alkali metal reaction studies. In addition, the Fusion Safety Support Studies program sponsored intermediate-size safety reaction tests in the LSFF with lithium and lithium lead compounds. The facility has also been used to store and treat alkali metal waste, therefore the LSFF is subject to the regulatory requirements for the storage and treatment of dangerous waste. Closure will be conducted pursuant to the requirements of the Washington Administrative Code (WAC) 173-303-610. This closure plan presents a description of the facility, the history of waste managed, and the procedures that will be followed to close the LSFF as an Alkali Metal Treatment Facility.

    2007-03-01

    This paper introduces Dr.LiTHO, a research and development oriented lithography simulation environment developed at Fraunhofer IISB to flexibly integrate our simulation models into one coherent platform. We propose a light-weight approach to a lithography simulation environment: The use of a scripting (batch) language as an integration platform. Out of the great variety of different scripting languages, Python proved superior in many ways: It exhibits a good-natured learning-curve, it is efficient, available on virtually any platform, and provides sophisticated integration mechanisms for existing programs. In this paper, we will describe the steps, required to provide Python bindings for existing programs and to finally generate an integrated simulation environment. In addition, we will give a short introduction into selected software design demands associated with the development of such a framework. We will especially focus on testing and (both technical and user-oriented) documentation issues. Dr.LiTHO Python files contain not only all simulation parameter settings but also the simulation flow, providing maximum flexibility. In addition to relatively simple batch jobs, repetitive tasks can be pooled in libraries. And as Python is a full-blown programming language, users can add virtually any functionality, which is especially useful in the scope of simulation studies or optimization tasks, that often require masses of evaluations. Furthermore, we will give a short overview of the numerous existing Python packages. Several examples demonstrate the feasibility and productiveness of integrating Python packages into custom Dr.LiTHO scripts.

    Full Text Available U ovome radu analiziraju se sve dosada utvrđene granice jadranskog podmorja kao i one koje tak valja utvrditi, posebice u svjetlu novih istraživanja njegovih prirodnih bogatstava. Uz Hrvatsku i Italiju, koje dijele najveći dio morskog dna i podzemlja u Jadranu, pravo na epikontinentski pojas imaju i Crna Gora te Albanija. Dvije jadranske države s kratkim obalama – Bosna i Hercegovina te Slovenija, države su u nepovoljnome geografskom položaju koje ne mogu imati epikontinentski pojas kao prirodni produžetak svoga kopnenog područja. Podmorski prostori tih država završavaju stoga na vanjskoj granici njihovih teritorijalnih mora. Osim razmatranja tih granica i sporazumno utvrđenih granica epikontinentskih pojaseva, autorice se kritički osvrću i na jednostrane akte Slovenije o proglašenju njezinoga epikontinentskog pojasa iz 2005. godine kao potpuno pravno neutemeljene akte. U središtu pozornosti ovoga rada je razmatranje granice koja dijeli podmorske prostore Hrvatske i Italije kao buduće granice dviju država i nad morskim dnom. Ta bi granična crta, u skladu s Konvencijom UN-a o pravu mora, trebala postati – jedinstvena morska granica njihovih epikontinentskih i gospodarskih pojaseva (odnosno ekološke zone Italije i zaštićenoga ekološko-ribolovnog pojasa Republike Hrvatske. Takva višefunkcionalna jedinstvena granična crta u najboljem je interesu pravne sigurnosti u svim načinima korištenja mora, a u međunarodnoj sudskoj i arbitražnoj praksi posljednjih desetljeća u potpunosti je zamijenila povlačenje različitih crta razgraničenja za više pojaseva u istome morskom prostoru. S obzirom na rezultate nedavno provedenih istraživanja potencijalnih nalazišta nafte i plina u južnom Jadranu, u radu se upozorava i na potrebu što skorijeg povlačenja crte bočnog razgraničenja epikontinentskih pojaseva Hrvatske i Crne Gore. Autorice analiziraju moguće pravce te nove granice, uzimajući u obzir znatno odstupanje od

    A well-characterized allergen of Lolium perenne (perennial rye grass) pollen, Lol p III, has been used as a model antigen to study the genetic control of the human immune response. Associations between HLA type and IgE or IgG antibody (Ab) responsiveness to Lol p III were studied in two groups of skin-test-positive Caucasoid adults (N = 135 and 67). We found by nonparametric and parametric analyses that immune responsiveness to Lol p III was significantly associated with HLA-DR3 and DR5. No association was found between any DQ type and immune responsiveness to Lol p III. Geometric mean IgE or IgG Ab levels to Lol p III were not different between B8+, DR3+ subjects and B8-, DR3+ subjects, showing that HLA-B8 had no influence on the association. Lol p III IgG Ab data obtained on subjects after grass antigen immunotherapy showed that 100% of DR3 subjects and 100% of DR5 subjects were Ab+. A comparison of all the available protein sequences of DRB gene products showed that the first hypervariable region of DR3 and DR5 (and DRw6), and no other region, contains the sequence Glu9-Tyr-Ser-Thr-Ser13. Our observations are consistent with the possibility that immune responsiveness to the allergen Lol p III is associated with this amino acid sequence in the first hypervariable region of the DR beta 1 polypeptide chain.

    In this interview in Dr Fordham's 83rd year he describes how he started to work with children, and how Mrs Jung was supportive. He talks about the initial suspicion this interest generated in the wider Jungian community. He refers to his acceptance of and interest in the psychotic elements in child analysis and his transference-based approach to working with these elements. He reflects on his own birth, his work with evacuee children in hostels during the war years and the politics of supervision. He describes the core Jungian concepts which underpinned his work and the theoretical differences from the Kleinian and Anna Freudian positions.

    Gaiadendron punctatum (Ruiz and Pavon) G. Don and Ternstroemia meridionalis mutis ex l.f. are ornithochorous species of the high Andean forest; the first is abundant at natural municipal park Rancheria and the second rare at local level. The seed rain and fruiting phenology of G. punctatum and T. meridionalis were evaluated. Records were kept between March and December of 2010. This period included dry and wet seasons. Eight traps with a recollection surface of 1 m 2 were installed. Fruiting of G. punctatum and T. meridionalis was continued with a high percentage of unripe fruits. The higher fruiting was shown in the wet season. Both species presented seed rain during all the study. G. punctatum had higher seed rain with an average of 169/m 2 ; while t. meridionalis only 50 seeds/m 2 . Most abundance of G. punctatums seeds was recorded in the dry season, while for T. meridionalis in wet season. In spite of low seed rain for T. meridionalis it showed a high percentage of viable seeds. G. punctatum presented more propagules that could explain the high number of individuals by area. Although the number of seeds of T. meridionalis is not very high, it represents a potential for prevalence of this specie and the need of looking for factors that to block the persistence of this propagules.

    Full Text Available A través de la confrontación de las tesis más relevantes que Atienza y Ruiz Manero proponen en su artículo "Dejemos atrás el positivismo jurídico", el autor pretende mostrar-a partir de la respuesta a las preguntas "¿qué iuspositivismo hemos de dejar atrás?", "¿por qué?" y "¿cómo?"- que existen en el iuspositivismo debilidades explicativas graves respecto de la realidad jurídica, y que estas están vinculadas tanto al escepticismo ético como a la negación de la existencia de un Derecho natural en sentido propio, es decir, de raigambre antropológico-metafísica. Por otro lado, se tratará de evidenciar que dichas debilidades explicativas le son comunes también a los intentos pragmático-constructivistas de superación del iuspositivismo por lo que, en última instancia, ninguno de dichos esquemas conceptuales puede dar cuenta cabal de una realidad como los derechos humanos que se presentan como deudas ético-jurídicas inexcusables fundamentadas en la dignidad ontológica de todos los seres humanos.

This production takes a comic look at scientific methods, as applied to a common object: the pancake.

And although these zany sketches are nothing short of absurd, the audience is drawn in more often than you might expect… and taken on quite an unexpected journey into the behavioural disorders, personality quirks and psychoanalysis of the base pancake. This show playfully mocks scientific logic and discourse, forcing the audience to reflect on their gullibility in the face of science and its impenetrable jargon. It purports to be neither explanation nor illustration of scientific fact,...

  9. Pathogenesis of Human Diffusely Adhering Escherichia coli Expressing Afa/Dr Adhesins (Afa/Dr DAEC): Current Insights and Future Challenges

    Science.gov (United States)

    2014-01-01

    SUMMARY The pathogenicity and clinical pertinence of diffusely adhering Escherichia coli expressing the Afa/Dr adhesins (Afa/Dr DAEC) in urinary tract infections (UTIs) and pregnancy complications are well established. In contrast, the implication of intestinal Afa/Dr DAEC in diarrhea is still under debate. These strains are age dependently involved in diarrhea in children, are apparently not involved in diarrhea in adults, and can also be asymptomatic intestinal microbiota strains in children and adult. This comprehensive review analyzes the epidemiology and diagnosis and highlights recent progress which has improved the understanding of Afa/Dr DAEC pathogenesis. Here, I summarize the roles of Afa/Dr DAEC virulence factors, including Afa/Dr adhesins, flagella, Sat toxin, and pks island products, in the development of specific mechanisms of pathogenicity. In intestinal epithelial polarized cells, the Afa/Dr adhesins trigger cell membrane receptor clustering and activation of the linked cell signaling pathways, promote structural and functional cell lesions and injuries in intestinal barrier, induce proinflammatory responses, create angiogenesis, instigate epithelial-mesenchymal transition-like events, and lead to pks-dependent DNA damage. UTI-associated Afa/Dr DAEC strains, following adhesin-membrane receptor cell interactions and activation of associated lipid raft-dependent cell signaling pathways, internalize in a microtubule-dependent manner within urinary tract epithelial cells, develop a particular intracellular lifestyle, and trigger a toxin-dependent cell detachment. In response to Afa/Dr DAEC infection, the host epithelial cells generate antibacterial defense responses. Finally, I discuss a hypothetical role of intestinal Afa/Dr DAEC strains that can act as “silent pathogens” with the capacity to emerge as “pathobionts” for the development of inflammatory bowel disease and intestinal carcinogenesis.

    Full Text Available The Death Receptor 6 (DR6 protein is elevated in the serum of ovarian cancer patients. We tested DR6 serum protein levels as a diagnostic/predictive biomarker in several epithelial tumors and sarcomas.DR6 gene expression profiles were screened in publically available arrays of solid tumors. A quantitative immunofluorescent western blot analysis was developed to test the serum of healthy controls and patients with sarcoma, uterine carcinosarcoma, bladder, liver, and pancreatic carcinomas. Change in DR6 serum levels was used to assay the ability of DR6 to predict the response to therapy of sarcoma patients.DR6 mRNA is highly expressed in all tumor types assayed. Western blot analysis of serum DR6 protein demonstrated high reproducibility (r = 0.97. Compared to healthy donor controls, DR6 serum levels were not elevated in patients with uterine carcinosarcoma, bladder, liver, or pancreatic cancers. Serum DR6 protein levels from adult sarcoma patients were significantly elevated (p<0.001. This was most evident for patients with synovial sarcoma. Change in serum DR6 levels during therapy correlated with clinical benefit from therapy (sensitivity 75%, and positive predictive value 87%.DR6 may be a clinically useful diagnostic and predictive serum biomarker for some adult sarcoma subtypes.Diagnosis of sarcoma can be difficult and can lead to improper management of these cancers. DR6 serum protein may be a tool to aid in the diagnosis of some sarcomatous tumors to improve treatment planning. For patients with advanced disease, rising DR6 levels predict non-response to therapy and may expedite therapeutic decision making and reduce reliance on radiologic imaging.

    Dr Milenko Petrović was one of the very distinguished physicians in the history of Sombor city, who significantly contributed to the development of health care in Voivodina. His father Dimitrije was a professor in the High Teacher-training School in Sombor, recognized writer and politician of his epoch. He was born in Sombor in 1884, where he was educated and finished grammar school. For medical studies he moved to Budapest as a boarder of the famous Tekelianum, and graduated in 1908. He started specialisation in surgery, but being a great patriot he voluntarily recruited in the Serbian army to fight in Balkan liberation wars against Turkey. For his excellent work as a war surgeon he obtained many recognitions. After completing specialization in surgery in Debrecin, he returned to his native city Sombor, where he intended to practice as a physician, but because af the outbreak of the first world he was mobilized and sent to the front in Galicia. After the war he again returned to Sombor where he was immediatelly nominated for the main county physician and then begins his fruitful many year's work on the establishment and promotion of the health care in Sombor and broader territory. As the main county phsician he initiated the foundation and construction of the hospital in Sombor, because of high mortality rate among children, and spreading of contagious diseases like tuberculosis and trachoma. The construction of the hospital was completed in 1925 and Dr. Petrović was appointed its first director and this duty he performed for many years till the World War 2 in 1941. Under his management the hospital in Sombor became one of the best quality hospitals in the country and gave a big contribution to the promotion of health of the inhabitants of Voivodina. In spite of his extensive duties in the hospital. Dr. Milenko Petrović was very much engaged in social work, as the president of library "Laza Kosti ć". in the Soko association, Fire brigade, Rotary club, and he

    2018-03-01

    Gaia DR1 Tycho-Gaia Astrometric Solution parallaxes, Tycho-2 photometry, and reddening/extinction estimates from nine data sources for 38 074 giants within 415 pc from the Sun are used to compare their position in the Hertzsprung-Russell diagram with theoretical estimates, which are based on the PARSEC and MIST isochrones and the TRILEGAL model of the Galaxy with its parameters being widely varied. We conclude that (1) some systematic errors of the reddening/extinction estimates are the main uncertainty in this study; (2) any emission-based 2D reddening map cannot give reliable estimates of reddening within 415 pc due to a complex distribution of dust; (3) if a TRILEGAL's set of the parameters of the Galaxy is reliable and if the solar metallicity is Z 50°, give the best fit of the empirical and theoretical data with each other.

    Campos-Navarro, Roberto; Ruiz-Llanos, Adriana

    2004-01-01

    Albert Schweitzer (1875-1965) was a young and promising German who at age 29 decided to undertake the profession of Medical Doctor at the University of Strassburg after finishing a career in musical studies in Paris (1899) and obtaining in Berlin a doctoral degree in Philosophy and Theology. Surprisingly, Albert Schweitzer, despite his comfortable life in Europe, decided in 1913 to practice his medical career in a remote and small Equatorial African country. He devoted nearly 50 years of his life caring for the Black population at Lamaberene, where he built a hospital. In this paper, we attempt to develop some theoretical aspects related with interculturality in the medical practice of Dr. Albert Schweitzer. We begin by considering certain sociocultural variables in hospitals that give care to patients with cultural characteristics that are substantially different from those of the health care personnel who organize, administer, and execute medical functions.

  17. The Chymistry of "The Learned Dr Plot" (1640-96).

    2014-01-01

    In the seventeenth century, there were developing norms of openness in the presentation of scientific knowledge that were at odds with traditions of secrecy among chymists, particularly practitioners of chrysopoeia, or the transmutation of metals. This chapter analyzes how Dr. Robert Plot, the first professor of chymistry at Oxford, negotiated these boundaries within an institutional context. I first delineate his chymical and experimental practice, which incorporated procedures from medieval alchemical sources, particularly the Lullian corpus, as well as more novel practices from seventeenth-century chymistry. Then, I analyze how personal and institutional ambitions and economic considerations shaped to what extent Plot negotiated the boundaries between secrecy and the public dissemination of chymical knowledge.

    Autonomous vehicles require highly reliable navigation capabilities. For example, a lane-following method cannot be applied in an intersection without lanes, and since typical lane detection is performed using a straight-line model, errors can occur when the lateral distance is estimated in curved sections due to a model mismatch. Therefore, this paper proposes a localization method that uses GPS/DR error estimation based on a lane detection method with curved lane models, stop line detection, and curve matching in order to improve the performance during waypoint following procedures. The advantage of using the proposed method is that position information can be provided for autonomous driving through intersections, in sections with sharp curves, and in curved sections following a straight section. The proposed method was applied in autonomous vehicles at an experimental site to evaluate its performance, and the results indicate that the positioning achieved accuracy at the sub-meter level.

    Sensitive high angular resolution (∼2'') CO(2-1) line observations made with the Submillimeter Array of the flow emanating from the high-mass star-forming region DR21 located in the Cygnus X molecular cloud are presented. These new interferometric observations indicate that this well known enigmatic outflow appears to have been produced by an explosive event that took place about 10,000 years ago, and that might be related to the disintegration of a massive stellar system such as the one that occurred in Orion Becklin-Neugebauer/Kleinman-Low 500 years ago, but about 20 times more energetic. This result therefore argues in favor of the idea that the disintegration of young stellar systems perhaps is a frequent phenomenon present during the formation of massive stars. However, many more theoretical and observational studies are still needed to confirm our hypothesis.

  2. GPS/DR Error Estimation for Autonomous Vehicle Localization

    Directory of Open Access Journals (Sweden)

    Byung-Hyun Lee

    2015-08-01

    Full Text Available Autonomous vehicles require highly reliable navigation capabilities. For example, a lane-following method cannot be applied in an intersection without lanes, and since typical lane detection is performed using a straight-line model, errors can occur when the lateral distance is estimated in curved sections due to a model mismatch. Therefore, this paper proposes a localization method that uses GPS/DR error estimation based on a lane detection method with curved lane models, stop line detection, and curve matching in order to improve the performance during waypoint following procedures. The advantage of using the proposed method is that position information can be provided for autonomous driving through intersections, in sections with sharp curves, and in curved sections following a straight section. The proposed method was applied in autonomous vehicles at an experimental site to evaluate its performance, and the results indicate that the positioning achieved accuracy at the sub-meter level.

    FEMoM3DR is a computer code written in FORTRAN 77 to compute radiation characteristics of antennas on 3D body using combined Finite Element Method (FEM)/Method of Moments (MoM) technique. The code is written to handle different feeding structures like coaxial line, rectangular waveguide, and circular waveguide. This code uses the tetrahedral elements, with vector edge basis functions for FEM and triangular elements with roof-top basis functions for MoM. By virtue of FEM, this code can handle any arbitrary shaped three dimensional bodies with inhomogeneous lossy materials; and due to MoM the computational domain can be terminated in any arbitrary shape. The User's Manual is written to make the user acquainted with the operation of the code. The user is assumed to be familiar with the FORTRAN 77 language and the operating environment of the computers on which the code is intended to run.

    GENESI-DR (Ground European Network for Earth Science Interoperations - Digital Repositories) is a European Commission (EC)-funded project, kicked-off early 2008 lead by ESA; partners include Space Agencies (DLR, ASI, CNES), both space and no-space data providers such as ENEA (I), Infoterra (UK), K-SAT (N), NILU (N), JRC (EU) and industry as Elsag Datamat (I), CS (F) and TERRADUE (I). GENESI-DR intends to meet the challenge of facilitating "time to science" from different Earth Science disciplines in discovery, access and use (combining, integrating, processing, …) of historical and recent Earth-related data from space, airborne and in-situ sensors, which are archived in large distributed repositories. "Discovering" which data are available on a "geospatial web" is one of the main challenges ES scientists have to face today. Some well- known data sets are referred to in many places, available from many sources. For core information with a common purpose many copies are distributed, e.g., VMap0, Landsat, and SRTM. Other data sets in low or local demand may only be found in a few places and niche communities. Relevant services, results of analysis, applications and tools are accessible in a very scattered and uncoordinated way, often through individual initiatives from Earth Observation mission operators, scientific institutes dealing with ground measurements, service companies or data catalogues. In the discourse of Spatial Data Infrastructures, there are "catalogue services" - directories containing information on where spatial data and services can be found. For metadata "records" describing spatial data and services, there are "registries". The Geospatial industry coins specifications for search interfaces, where it might do better to reach out to other information retrieval and Internet communities. These considerations are the basis for the GENESI-DR scientific portal, which adopts a simple model allowing the geo-spatial classification and discovery of

    Nurses have long attempted to secure a unique identity for the profession. Many scholars are now promoting an interdisciplinary framework for nursing practice. Fawcett is convinced that interdisciplinary practice poses a danger for nursing to lose its identity and that interdisciplinary practice cannot be successful if members of each discipline do not understand the conceptual models, practice, and research of their own discipline. Dr. Janie Butts and Dr. Karen Rich interviewed Dr. Jacqueline Fawcett about her views related to discipline-specific knowledge and nursing's future. The authors conclude that Fawcett's scientific foundation gives nursing the solidarity and power necessary to determine the unique internal goods of its practice.

    Preparations are under way to sell the sodium stored in the 1720-DR tank in the 1720-DR building. This will require that the tank, as well as the 1720-DR facility, be moved to the 300 Area, so that the sodium may be melted and transferred into a railroad tanker car. Because the sodium is a hazardous material and is being shipped in a nonspecification packaging, a safety evaluation for packaging (SEP) is required. This SEP approves the sodium-filled tank for a single shipment from the 105-DR area to the 300 Area

    In conclusion, DR-specific suppressor cells can be induced by repeated in vitro sensitizations. They were able to decrease a secondary proliferation, to suppress consistently, in a primary proliferative assay, when added as third cells (primed twice against a DR antigen [PLT II] and γ-irradiated), the response of unprimed cells towards stimulating cells, which share a DR specificity with the priming cell of the PLT II. The suppression follows the D part of the recombinant haplotype within an HLA-B/D recombinant family and is specific for the DR antigen used twice as stimulator for production of the PLT II

    DR 2 (Danish Reactor 2), one of the research reactors at the Riso site, has been in the process of being decommissioned during the last two years. The decommissioning will be completed in 2008. The reactor went critical for the first time in late 1958 and was shut down in 1975. The construction was a 5 MW light-water moderated and cooled tank type reactor. Although the process of decommissioning was formally initiated in 2005, it was preceded by a characterization project with the purpose of determining activity contents in key materials and dose rates at relevant spots in the reactor. The paper describes the removal of neutron beam plugs, grid plate and a thermal column with focus on radiation protection issues. The primary objective is, however, to describe the measures taken to control radiation doses during the removal of the reactor block concrete and the reactor tank.The demolition and removal of concrete was done by an external contractor. The contractor had to comply with a comprehensive set of requirements. This included splitting activated concrete from concrete containing activities below clearance levels with no use of fluids of any kind, as the risk of not being able to control diffusion of contaminated fluids was an important issue. The experience from the decommissioning of the DR 1 reactor in 2005 showed that water-cooled cutting made it very difficult to monitor the levels of air contamination as the filters of the air monitors were blocked frequently. Certainly, dry cutting turned out to be a great technical challenge to the external contractor. Another demand was that the work should take place inside a de-pressurized containment in order to control air contamination and thereby minimize internal doses. The experience gathered from the practical implementation of dose reducing measures will be discussed. Problems involving the use of external contractors will be discussed, including training of personnel with no prior knowledge of radioactivity

    We describe a young woman who suddenly began mirror writing with her right hand and has not reverted to normal writing for more than 6 years, although she writes normally with her left hand. She is ambidextrous, although she had previously used only her right hand for writing and drawing. Since it is much easier for her to use right-handed mirror writing, she uses her left hand only for writing meant to be read by others and her right hand for all other writing. Her hobbies are sculpture and painting, and her chief complaint is migraine accompanied by sensory and perceptive disturbances.

    Islet autoimmunity is initiated in infancy, and primary prevention trials require children at high genetic risk to be identified before autoantibodies appear. To inform screening strategies, we evaluated risks of autoimmunity and diabetes associated with HLA DR3-DQ2/DR4-DQ8 in U.K. families. Extended HLA haplotypes were determined in 2,134 siblings from the Bart's-Oxford Study followed to a median age of 22 years. Risks of diabetes and islet autoimmunity (more than two antibodies) were estimated by survival analysis. Of 138 informative DR3-DQ2/DR4-DQ8 siblings, 63% shared both haplotypes with their diabetic proband, 29% shared one, and 8% shared neither. In HLA-identical DR3-DQ2/DR4-DQ8 siblings, the cumulative risk of diabetes by age 15 was 17% (vs. 6% in those sharing one haplotype or none; P = 0.095). Risk varied, however, with the age at the onset of diabetes in the proband; the cumulative risk of autoimmunity and/or diabetes by age 15 was 61% in siblings of probands diagnosed when younger than 10 years old compared with only 4.7% in those diagnosed after age 10 years (P sibling risk. This suggests that non-HLA genes or epigenetic/environmental factors that accelerate the progression of type 1 diabetes in the proband strongly affect risk in siblings.

    Dr. Lisa Monaco, Marshall Space Flight Center's (MSFC's) project scientist for the Lab-on-a-Chip Applications Development (LOCAD) program, examines a lab on a chip. The small dots are actually ports where fluids and chemicals can be mixed or samples can be collected for testing. Tiny channels, only clearly visible under a microscope, form pathways between the ports. Many chemical and biological processes, previously conducted on large pieces of laboratory equipment, can now be performed on these small glass or plastic plates. Monaco and other researchers at MSFC in Huntsville, Alabama, are customizing the chips to be used for many space applications, such as monitoring microbes inside spacecraft and detecting life on other planets. The portable, handheld Lab-on-a Chip Application Development Portable Test System (LOCAD-PTS) made its debut flight aboard Discovery during the STS-116 mission launched December 9, 2006. The system allowed crew members to monitor their environment for problematic contaminants such as yeast, mold, and even E.coli, and salmonella. Once LOCAD-PTS reached the International Space Station (ISS), the Marshall team continued to manage the experiment, monitoring the study from a console in the Payload Operations Center at MSFC. The results of these studies will help NASA researchers refine the technology for future Moon and Mars missions. (NASA/MSFC/D.Stoffer)

    The year of 2004 was the 100th anniversary of death of the poet and physician Dr. Jovan Jovanović Zmaj. Jovan Jovanović Zmaj was born in 1833 in Novi Sad, and died in 1904 in Sremska Kamenica J.J. Zmaj himself studied law and worked in the Novi Sad magistrate court. It was not until he turned 30 that he began practicing medicine. He developed as a poet as early as during his studies. He remained loyal to the vocations of physician and poet throughout his life. He wrote over 5000 poems, ranging from those for children through those for adults and those with which he addressed the rulers satirically. He was a founder of a number of magazines (Javor, Neven, Komarac, Danica). At that time of Romanticism, the work of J.J. Zmaj also had a national character. However, he succeeded in achieving something more: he introduced a literary genre till then unknown in Serb literature--literature for children. Through his genre he promoted not only Serbian language but also hygiene, by which he played a significant health care role, similar to that played by his friend Milan Jovanović Batut, only from a different aspect. He also used to draw, and his drawing of the emblem of the Serbian Literary Association has remained on the cover of every book published by it until these days.

    In this work, we present a catalog of 2651 carbon stars from the fourth Data Release (DR4) of the Large Sky Area Multi-Object Fiber Spectroscopy Telescope (LAMOST). Using an efficient machine-learning algorithm, we find these stars from more than 7 million spectra. As a by-product, 17 carbon-enhanced metal-poor turnoff star candidates are also reported in this paper, and they are preliminarily identified by their atmospheric parameters. Except for 176 stars that could not be given spectral types, we classify the other 2475 carbon stars into five subtypes: 864 C-H, 226 C-R, 400 C-J, 266 C-N, and 719 barium stars based on a series of spectral features. Furthermore, we divide the C-J stars into three subtypes, C-J(H), C-J(R), and C-J(N), and about 90% of them are cool N-type stars as expected from previous literature. Besides spectroscopic classification, we also match these carbon stars to multiple broadband photometries. Using ultraviolet photometry data, we find that 25 carbon stars have FUV detections and that they are likely to be in binary systems with compact white dwarf companions.

  4. The case of the missing fingerprints or Dr Watson's cosmology

    Longair, M.S.

    1987-01-01

    The cosmological problem has four main areas of uncertainty -the origin of isotropy of the universe, the origin of the fluctuations from which galaxies form, the explanation of why we live in a matter universe rather than one composed of equal amounts of matter and antimatter and why the Universe seems to be within a factor of 10 of the critical, flat universe. These cannot be explained satisfactorily within the Hot Big Bang theory after a millisecond or so. The solutions are presumed, therefore, to lie in the very early universe when it was less than about a millisecond old. The clues which lead to this conclusion are set out in terms of a detective story with Sherlock Holmes explaining the facts about the universe to Dr Watson. Holmes first explains the size of the universe in terms of distances and sizes of stars, galaxies and galaxy clusters. Evidence from pictures of the universe at different temperatures, (X-ray pictures, gamma-ray pictures, far infra-red pictures and pictures at radio and millimetre wavelengths) is presented. Holmes then starts to build up a realistic model of the universe using two of the facts collected (the isotropy of the universe and the expansion of the universe), one assumption (the cosmological principle) and one theory of gravity (General Relativity). However the universe which emerges does not solve the four problems mentioned. Quasars, which provide information (illustrated) from earlier epochs of the universe may, therefore, help to solve the problems. (U.K.)

    In this work, we built all sky index files from Gaia DR1 catalogue for the high-precision astrometric field solution and the precise WCS coordinates of the moving objects. For this, we used build-astrometry-index program as a part of astrometry.net code suit. Additionally, we added astrometry.net's WCS solution tool to our previously developed software which is a fast and robust pipeline for detecting moving objects such as asteroids and comets in sequential FITS images, called A-Track. Moreover, MPC module was added to A-Track. This module is linked to an asteroid database to name the found objects and prepare the MPC file to report the results. After these innovations, we tested a new version of the A-Track code on photometrical data taken by the SI-1100 CCD with 1-meter telescope at TÜBİTAK National Observatory, Antalya. The pipeline can be used to analyse large data archives or daily sequential data. The code is hosted on GitHub under the GNU GPL v3 license.

    We analyze the kinematics of thick disk and halo stars observed by the Large Sky Area Multi-Object Fiber Spectroscopic Telescope. We have constructed a sample of 7993 F, G, and K nearby main-sequence stars (d < 2 kpc) with estimates of position (x, y, z) and space velocity (U, V, W) based on color and proper motion from the Sloan Digital Sky Survey DR9 catalog. Three 'phase-space overdensities' are identified in (V, √(U 2 +2V 2 )) with significance levels of σ > 3. Two of them (the Hyades-Pleiades stream and the Arcturus-AF06 stream) have been identified previously. We also find evidence for a new stream (centered at V ∼ –180 km s –1 ) in the halo. The formation mechanisms of these three streams are analyzed. Our results support the hypothesis that the Arcturus-AF06 stream and the new stream originated from the debris of a disrupted satellite, while the Hyades-Pleiades stream has a dynamical origin.

    In electricity markets, traditional demand side management programs are slowly getting replaced with demand response (DR) programs. These programs have evolved since the early pilot programs launched in late 1990s. With the changes in market rules the opportunities have generally increased for DR for participating in emergency, economic and ancillary service programs. In recent times, various regulators have suggested that DR can also be used as a solution to meet supply - demand fluctuations in scenarios with significant penetration of variable renewable sources in grid. This paper provides an overview of the evolution of the DR programs in PJM and NYISO markets as well as analyzes current opportunities. Although DR participation has grown, most of the current participation is in the reliability programs, which are designed to provide load curtailment during peak days. This suggests that there is a significant gap between perception of ability of DR to mitigate variability of renewables and reality of current participation. DR in future can be scaled to play a more dynamic role in electricity markets, but that would require changes both on technology as well as policy front. Advances in building technologies and energy storage combined with appropriate price signals can lead to enhanced DR participation. (author)

    The influence of the work of Dr. Guillermo Contreras Da Silva and his colaborators on the evolution of microbiology in Chile is briefly analyzed. Dr. Contreras was trained in modern virology at Yale University with Dr. J. Melnick under the sponsorhip of the Rockefeller Foundation. During this training, he used serological methods to classify Cocksakie viruses. After his return to Chile, he studied the epidemiology of enteroviruses, including poliovirus. His laboratory, the country's first in modern virology, took an active role in Chile's first Sabin polio vaccination in 1961. Dr. Contreras and his group transformed the teaching and the character of microbiology in Chile from a descriptive medically oriented discipline into an autonomous, quantitative and experimental science. They modernized microbiology with the introduction of molecular biology and microbial genetics and fostered collaborations with allied biological sciences. Dr. Contreras was a Guggenheim Fellow, and until his retirement, was the Chief of the Viral Products Division, Bureau of Biologies, Ottawa, Canada.

    Human leukocyte antigen (HLA)-DRB1 allele polymorphisms have been reported to be associated with systemic lupus erythematosus (SLE) susceptibility, but the results of these previous studies have been inconsistent. The purpose of the present study was to systematically summarize and explore whether specific HLA-DRB1 alleles confer susceptibility or resistance to SLE and lupus nephritis. This review was guided by the preferred reporting items for systematic reviews and meta-analyses (PRISMA) approach. A comprehensive search was made for articles from PubMed, Medline, Elsevier Science, Springer Link and Cochrane Library database. A total of 25 case-control studies on the relationship between gene polymorphism of HLA-DRB l and SLE were performed and data were analyzed and processed using Review Manager 5.2 and Stata 11.0. At the allelic level, HLA-DR4, DR11 and DR14 were identified as protective factors for SLE (0.79 [0.69,0.91], P  0.05). DR4 and 11 (OR, 0.55 [0.39, 0.79], P  0.05; 0.90 [0.64, 1.27], P > 0.05; 0.61 [0.36, 1.03], P > 0.05, respectively) were not statistically significant between the lupus nephritis and control groups. The HLA-DR4, DR11, DR14 alleles might be protective factors for SLE and HLA-DR3, DR9, DR15 were potent risk factors. In addition, HLA-DR4 and DR11 alleles might be protective factors for lupus nephritis and DR3 and DR15 suggest a risk role. These results proved that HLA-DR3, DR15, DR4 and DR11 might be identified as predictors for lupus nephritis and SLE. © 2014 Asia Pacific League of Associations for Rheumatology and Wiley Publishing Asia Pty Ltd.
