Doris Salcedo: memórias da exclusão e violência

The Colombian artist Doris Salcedo demonstrates, through his works, the universal vulnerability of human beings. The artist uses a concrete materiality such as furniture that is part of everyday life, and builds abstract works, sometimes unusual images, requiring the reader to excavate layers of memory and adjust his perception to decipher the poetic deviation and establish the sense. The theme is violence that humanity was and still been submitted in all corners of the world, particularly Latin America in the stories of oppression, dictatorships, civil wars, civil rights violated, etc. Her works echo the "silent scream" of the vulnerable.

Tecnologias de Informação e Comunicação (TICs) e literatura, uma aposta notável

The aim of this study was to develop a qualitative research of bibliographic nature, in order to verify how has been the use of new Information and Communication Technologies (ICTs) and literary reading in early childhood education.. It is believed to be necessary for children, since their early childhood, to, be in contact with various literary works of aesthetic value, which will enable them to understand this particular literary language - and the imagery that comes with it - what can instigate appreciate literature and get the reading habit. The use of ICTs by children beyond the use of games and watching stories on computers, tablets and smartphones, for example, for the production of videos and slides or creating stories, enable new experiences of redesigning and construction of knowledge and culture. The idea for this research came from reading the numerous texts that deal with the need to understand the child as an active subject in the construction of culture and society, rather than as receiving reproductive and cultural orders (CRIANÇAS, 2012). In this sense, in addition to the newsletters Equity For Children: Latin America (CRIANÇAS, 2012), the understanding of childhood and child in the works of Walter O. Kohan (2005; 2006) supports this study. This research proposal was also based on authors and documents that point to the need to promote, since the first stages of Basic Education, the literary reading as a means of enjoyment and emancipation (LAJOLO 2001a; Barthes, 2007; FILIPOUSKY, 2009; BRAZIL, 2010; MACHADO, 2011; VASQUES, 2013), and an education connected to the technological advances of the twenty-first century (BRAZIL, 1997, CHAVES, 1998; DEMO, 2008)

Mary E. Frayser Papers - Accession 1

The Mary E. Frayser Papers consists of correspondence, speeches, reports, clippings, minutes, histories, family histories, constitutions and bylaws, membership lists, program notes, photographs, and other papers, relating to her work with the South Carolina Extension Service (1912-1940) Winthrop College, her involvement with the South Carolina Council for the Common Good (1935-1952), the South Carolina Federation of Women’s Clubs (1926-1952), the South Carolina Status of Women Conference (1945-1952), the South Carolina Division of the American Association of University Women (AAUW) (1929, 1935-1949), the South Carolina Interracial Institute (1938-1942), the South Carolina Division of the Southern Regional Council (1944-1951), and the South Carolina Conference of Social Work (1936-1967). There are also papers relating to Frayser’s efforts to promote social and economic legislation and participation by women in public affairs and her interest in libraries and work in the movement for the support of public libraries in South Carolina (1925-1968). Correspondents included G.H. Aault, Evan Chesterman, Wil Lou Gray, Sarah Hughes, Christine South Gee, and Maude Massey Rogers. This collection is a good source of women’s club activities in the twentieth century. Important areas of research would include the way club activity affected social and economic legislation in the state and the various forces involved in the movement for state tax supported libraries. While the papers do range from 1841 to 1953, the greater bulk of the papers extend from the early 1930s to about 1947. Since the work of the various women's club organizations were so inter-related, a researcher working with the papers of a particular organization for a particular time span should consider the Frayser papers of all other organizations. The related papers for the “Correspondence and Related Papers” series for particular organizations are generally similar and include: memoranda, outlines, reports, resolutions, minutes, etc. Additional Frayser information can be found by referring to the Winthrop University Archives (official records).

Segregated anatomical input to sub-regions of the rodent superior colliculus associated with approach and defense

The superior colliculus (SC) is responsible for sensorimotor transformations required to direct gaze toward or a way from unexpected, biologically salient events. Significant changes in the external world are signaled to SC through primary multisensory afferents, spatially organized according to a retinotopic topography. For animals, where anunexpected event could indicate the presence of either predator or prey, early decisions to approach or avoid are particularly important. Rodents' ecology dictates predators are most often detected initially as movements in upper visual field (mapped in medial SC), while appetitive stimuli are normally found in lower visual field (mapped in lateral SC). Our purpose was to exploit this functional segregation to reveal neural sites that can bias or modulate initial approach or avoidance responses. Small injections of Fluoro-Gold were made into medial or lateral sub-regions of intermediate and deep layers of SC (SCm/SCl). A remarkable segregation of input to these two functionally defined areas was found. (i) There were structures that projected only to SCm (e.g., specific cortical areas, lateral geniculate and suprageniculate thalamic nuclei, ventromedial and premammillary hypothalamic nuclei, and several brain-stem areas) or SCl (e.g., primary somatosensory cortex representing upper body parts and vibrissae and parvicellular reticular nucleus in the brainstem). (ii) Other structures projected to both SCm and SCl but from topographically segregated populations of neurons (e.g., zona incerta and substantia nigra pars reticulata). (iii) There were a few brainstem areas in which retrogradely labeled neurons were spatially overlapping (e.g., pedunculopontine nucleus and locus coeruleus). These results indicate significantly more structures across the rat neuraxis are in a position to modulate defense responses evoked from SCm, and that neural mechanisms modulating SC-mediated defense or appetitive behavior are almost entirely segregated.

From Amazonia to the Atlantic forest: Molecular phylogeny of Phyzelaphryninae frogs reveals unexpected diversity and a striking biogeographic pattern emphasizing conservation challenges

Documenting the Neotropical amphibian diversity has become a major challenge facing the threat of global climate change and the pace of environmental alteration. Recent molecular phylogenetic studies have revealed that the actual number of species in South American tropical forests is largely underestimated, but also that many lineages are millions of years old. The genera Phyzelaphryne (1 sp.) and Adelophryne (6 spp.), which compose the subfamily Phyzelaphryninae, include poorly documented, secretive, and minute frogs with an unusual distribution pattern that encompasses the biotic disjunction between Amazonia and the Atlantic forest. We generated >5.8 kb sequence data from six markers for all seven nominal species of the subfamily as well as for newly discovered populations in order to (1) test the monophyly of Phyzelaphryninae, Adelophryne and Phyzelaphryne, (2) estimate species diversity within the subfamily, and (3) investigate their historical biogeography and diversification. Phylogenetic reconstruction confirmed the monophyly of each group and revealed deep subdivisions within Adelophryne and Phyzelaphryne, with three major clades in Adelophryne located in northern Amazonia, northern Atlantic forest and southern Atlantic forest. Our results suggest that the actual number of species in Phyzelaphryninae is, at least, twice the currently recognized species diversity, with almost every geographically isolated population representing an anciently divergent candidate species. Such results highlight the challenges for conservation, especially in the northern Atlantic forest where it is still degraded at a fast pace. Molecular dating revealed that Phyzelaphryninae originated in Amazonia and dispersed during early Miocene to the Atlantic forest. The two Atlantic forest clades of Adelophryne started to diversify some 7 Ma minimum, while the northern Amazonian Adelophryne diversified much earlier, some 13 Ma minimum. This striking biogeographic pattern coincides with major events that have shaped the face of the South American continent, as we know it today. (C) 2012 Elsevier Inc. All rights reserved.

Henry Melson Stommel : from pionner to clasic

[EN] Stommel has been the most important physicist oceanographer of the second half of the XX century. Builder, to a great extent, of the present Dynamical Oceanography. He contributed to the transformation of the Oceanography from a sort of appendix of the studies of the Atmosphere to a new specialty of Geophysics. After graduating in Astronomy in Yale in 1942 he started his research participating in the WWII effort, collaborating together with many other future oceanographers, in support of the USA Navy. Research that was carried out in the Woods Hole Oceanographic Institution (WHOI). Between 1959 and 1978 he was professor of oceanography in Harvard U. first, and later in the Massachusetts Institute of Technology, returning to WHOI where he stayed until his death. Stommel established important and fundamental theories on the ocean global circulation and studied many other oceanographic phenomena. This theoretical activity he combined with not a less important observational one. He received many awards and hhonors, including the Craadford prize, equivalent to the Nobel in Geosciences.

Skeletal Markers of Activity: Methodological and Interpretative Reflections after the study of the whole Frassetto Sassari identified skeletal collection

Entheses (skeletal attachment sites of muscles and ligaments) and their pathologic modifications (enthesopathies) have long been used as skeletal markers of activity in bioarchaeological (reconstruction of past populations lifestyle) and forensic (personal identification) contexts. However, a functional interpretation of these markers have to deal critically with the multifactorial etiology of the same. Factors such as sex, age, genetic factors, mechanical stress, metabolic conditions, etc.. can compete to produce the observed morphological variability at each attachment site. The aim of this thesis has drawn on the ongoing debate about the informativeness of entheseal modifications as skeletal markers of activity and represent a deepening of the actual knowledge about the relationship between these characters and sex, age and physical activity. For this purpose, the whole "Frassetto” identified skeletal collection of Sassari (Sardinia, Italy) was analyzed. The collection includes the skeletal remains of about 600 individuals died in the late 19th and early 20th century for whom information regarding sex, age at death and, in many cases the occupation are known The results obtained highlight the great age importance on the entheseal modifications. The differences observed between sexes may reflect differences in the level or type of activity performed in life, but could also be related to a different bone tissue response to mechanical stress due to hormonal factors and different growth rates. The role of biomechanical stress related to professional activities remains doubtful. This is probably partly attributable to the analyzed sample characteristics (preponderance of farmers compared with other professions, different mean age of the considered professional subsamples), which has hampered the analysis of samples homogenous with regard to age, which is very influential on the entheses and enthesopathies expression.

A study of nitronyl and imino nitroxide radicals attached to heterocyclic cores

Stabile organische Radikale mit zusätzlichen Funktionalitäten wie Donor/Akzepotor Eigenschaften und Ligandeneignung für Übergangsmetallkomplexierung repräsentieren eine synthetische Herausforderung beim Streben nach der Konstruktion hochdimensionaler heterospin Strukturen. In diesem Hinblick wurden acht neue Hochspinbiradikal-Moleküle zusammen mit ihren Monoradikal- Pendants in dieser Arbeit hergestellt. Die Wahl der Liganden als organische Distanzhalter der Radikaleinheiten wurde auf stickstoffhaltige Heterozyklen (Pyridin und Pyrazol) gelenkt. Diese wurden weiterhin mit den stabilen Spinträgern Nitronylnitroxid- (NN) und Iminonitroxidfragmenten (IN) dekoriert. Ihre Synthese beinhaltete mehrstufige Umsetzungen (Brominierung, Iodierung, N- und Carbaldehyd Schutzgruppen, Stille-Kupplung, Grignard Reaktion, etc.) um die Mono- und Dicarbaldehyd-heterocyclenderivate als Schlüsselvorläufer der Radikaleinheiten zu gewinnen. Die Carbaldehyd-Zwischenstufen wurden Kondensationsreaktionen mit 2,3-Dimethyl-2,3-bis(hydroxylamino)-butan unterworfen (üblicherweise in Dioxan unter Argon für ~ 7 Tage), gefolgt von der Oxidation der Bis-hydroxylimidazolidin-Vorläufer unter Phasentransferkatalyse (NaIO4/H2O). Die Radikalmoleküle wurden mit verschiedenen spektroskopischen Methoden untersucht (FT/IR, UV/Vis/ EPR etc.) und ihre Einkristalle mit Röntgenstrahlbeugung gemessen. Die UV/VIS- Lösungsspektren zeigten in einem breiten Bereich verschiedener Lösungsmittelpolaritäten keine spezifische Wechselwirkung zwischen Lösungsmittel und Radikaleinheit, während ihre Stabilitäten in protischen Lösunsgmitteln wie MeOH stark abnahmen. Als Pulver konnten sie jedoch im Kühlschrank an der Luft für eine Jahr gelagert werden, ohne sich zu zersetzen. Die spektroskopischen Fingerabdrücke der Radikale wurden eindeutig identifiziert and erschienen stark abhängig vom Typ des pi-Ringsystems an das die Spinträger gekoppelt wurden. Basierend auf diesen Informationen wurde ein schnelles Protokoll etabliert, das eine direkte Zuordnung der Art der Radikale und ihrer Anzahl ermöglicht, sowie ihre Reinheit und Verunreinigungen zu definieren. In Lösung bestätigte die Analyse der EPR Spektren der Biradikale die starke Austauschwechselwirkung J zwischen den Radikalfragmenten über die Kopplungseinheiten (J >> an, an ist die Stickstoffhyperfeinkopplungskonstante). Dies wurde weiter unterstützt durch die Beobachtungen in gefrorener Lösung über die Nullfeldaufspaltungen und verbotenen Halbfeldübergänge (Δms = 2). Die Temperaturabhängigkeiten der Δms = 2 - EPR Signale wurden bis herunter auf 4 K gemessen und das exakte Vorzeichen und die Größe von J ermittelt. Diese Arbeit unterstreicht die Möglichkeit über synthetische Chemie eine Feineinstellung der „through bond“ Austauschwechselwirkung zwischen verwandten pi- und sigma- konjugierten Heterozyklen zu erreichen, in denen der S = 1 Grundzustand angenommen wird. Zusätzlich zeigten diese Resultate, dass die Übertragung der Spinpolarisation durch verschiedene Koppler sehr effektiv war.

I manoscritti miniati dell'Illustratore nella cultura figurativa del secondo quarto del XIV secolo

La tesi è dedicata alla personalità artistica dell’Illustratore, tra i protagonisti della miniatura bolognese degli anni trenta e quaranta del Trecento, così felicemente soprannominato da Roberto Longhi. Dopo un capitolo dedicato alla vicenda critica dell’artista, la tesi affronta il percorso artistico dell’Illustratore nell’ambito della decorazione libraria bolognese del secondo quarto del XIV secolo. Ho trattato le opere attribuite al’Illustratore insieme agli esempi contemporanei della miniatura bolognese, in modo da far emergere il ruolo di questo maestro nelle relazioni con il contesto cittadino. Nella successione cronologica dei manoscritti, emerge un nuovo sconvolgimento caotico che scardina l’ordine spaziale e compositivo delle opere iniziali debitrici del giottismo del Maestro del 1328. Il capitolo si conclude con alcune osservazioni sui rapporti tra il maestro e i suoi aiuti e sul rapporto con Buffalmacco. In questo capitolo sono inoltre presentate due nuove attribuzioni. Gli ultimi due capitoli sono un approfondimento sull’interazione tra il linguaggio figurativo dell’artista e la funzione dell’immagine quale forma di comunicazione visiva in stretta relazione con i testi scritti che accompagnano e sui caratteri della committenza, là dove è possibile definirli. La prima parte del terzo capitolo è dedicata all’illustrazione dei libri legales, mentre nella seconda parte si tratta di un caso particolare, le iniziali istoriate dell’Inferno e del Purgatorio di Dante Alighieri della Biblioteca Riccardiana di Firenze (ms. 1005), per molti aspetti riconducibili all’illustrazione giuridica. La mia intenzione in questo capitolo è di verificare come il caratteristico linguaggio narrativo espressivo e diretto dell’Illustratore abbia risposto alla funzione delle immagini dipinte nei codici giuridici di offrire una struttura materiale alla memorizzazione visiva per via di luoghi e figure dei contenuti di studio del diritto comune. In appendice alla tesi si trova un catalogo dei manoscritti decorati da miniature dell’Illustratore, comprensivo anche di una sezione per le opere di dubbia o erronea attribuzione.

Differential forms on Carnot groups

The main goal of this thesis is to understand and link together some of the early works by Michel Rumin and Pierre Julg. The work is centered around the so-called Rumin complex, which is a construction in subRiemannian geometry. A Carnot manifold is a manifold endowed with a horizontal distribution. If further a metric is given, one gets a subRiemannian manifold. Such data arise in different contexts, such as: - formulation of the second principle of thermodynamics; - optimal control; - propagation of singularities for sums of squares of vector fields; - real hypersurfaces in complex manifolds; - ideal boundaries of rank one symmetric spaces; - asymptotic geometry of nilpotent groups; - modelization of human vision. Differential forms on a Carnot manifold have weights, which produces a filtered complex. In view of applications to nilpotent groups, Rumin has defined a substitute for the de Rham complex, adapted to this filtration. The presence of a filtered complex also suggests the use of the formal machinery of spectral sequences in the study of cohomology. The goal was indeed to understand the link between Rumin's operator and the differentials which appear in the various spectral sequences we have worked with: - the weight spectral sequence; - a special spectral sequence introduced by Julg and called by him Forman's spectral sequence; - Forman's spectral sequence (which turns out to be unrelated to the previous one). We will see that in general Rumin's operator depends on choices. However, in some special cases, it does not because it has an alternative interpretation as a differential in a natural spectral sequence. After defining Carnot groups and analysing their main properties, we will introduce the concept of weights of forms which will produce a splitting on the exterior differential operator d. We shall see how the Rumin complex arises from this splitting and proceed to carry out the complete computations in some key examples. From the third chapter onwards we will focus on Julg's paper, describing his new filtration and its relationship with the weight spectral sequence. We will study the connection between the spectral sequences and Rumin's complex in the n-dimensional Heisenberg group and the 7-dimensional quaternionic Heisenberg group and then generalize the result to Carnot groups using the weight filtration. Finally, we shall explain why Julg required the independence of choices in some special Rumin operators, introducing the Szego map and describing its main properties.

A multi-objective genetic algorithm optimisation using variable speed pumps in water distribution systems

Due to its practical importance and inherent complexity, the optimisation of distribution networks for supplying drinking water has been the subject of extensive study for the past 30 years. The optimization is governed by sizing the pipes in the water distribution network (WDN) and / or optimises specific parts of the network such as pumps, tanks etc. or try to analyse and optimise the reliability of a WDN. In this thesis, the author has analysed two different WDNs (Anytown City and Cabrera city networks), trying to solve and optimise a multi-objective optimisation problem (MOOP). The main two objectives in both cases were the minimisation of Energy Cost (€) or Energy consumption (kWh), along with the total Number of pump switches (TNps) during a day. For this purpose, a decision support system generator for Multi-objective optimisation used. Its name is GANetXL and has been developed by the Center of Water System in the University of Exeter. GANetXL, works by calling the EPANET hydraulic solver, each time a hydraulic analysis has been fulfilled. The main algorithm used, was a second-generation algorithm for multi-objective optimisation called NSGA_II that gave us the Pareto fronts of each configuration. The first experiment that has been carried out was the network of Anytown city. It is a big network with a pump station of four fixed speed parallel pumps that are boosting the water dynamics. The main intervention was to change these pumps to new Variable speed driven pumps (VSDPs), by installing inverters capable to diverse their velocity during the day. Hence, it’s been achieved great Energy and cost savings along with minimisation in the number of pump switches. The results of the research are thoroughly illustrated in chapter 7, with comments and a variety of graphs and different configurations. The second experiment was about the network of Cabrera city. The smaller WDN had a unique FS pump in the system. The problem was the same as far as the optimisation process was concerned, thus, the minimisation of the energy consumption and in parallel the minimisation of TNps. The same optimisation tool has been used (GANetXL).The main scope was to carry out several and different experiments regarding a vast variety of configurations, using different pump (but this time keeping the FS mode), different tank levels, different pipe diameters and different emitters coefficient. All these different modes came up with a large number of results that were compared in the chapter 8. Concluding, it should be said that the optimisation of WDNs is a very interested field that has a vast space of options to deal with. This includes a large number of algorithms to choose from, different techniques and configurations to be made and different support system generators. The researcher has to be ready to “roam” between these choices, till a satisfactory result will convince him/her that has reached a good optimisation point.

Analysis of retrieved shoulder prostheses

In the last years the number of shoulder arthroplasties has been increasing. Simultaneously the study of their shape, size and strength and the reasons that bring to a possible early explantation have not yet been examined in detail. The research carried out directly on explants is practically nonexistent, this means a poor understanding of the mechanisms leading the patient and so the surgeon, to their removal. The analysis of the mechanisms which are the cause of instability, dislocation, broken, fracture, etc, may lead to a change in the structure or design of the shoulder prostheses and lengthen the life of the implant in situ. The idea was to analyze 22 explants through three methods in order to find roughness, corrosion and surface wear. In the first method, the humeral heads and/or the glenospheres were examined with the interferometer, a machine that through electromagnetic waves gives information about the roughness of the surfaces under examination. The output of the device was a total profile containing both roughness and information on the waves (representing the spatial waves most characteristic on the surface). The most important value is called "roughness average" and brings the average value of the peaks found in the local defects of the surfaces. It was found that 42% of the prostheses had considerable peak values in the area where the damage was caused by the implant and not only by external events, such as possibly the surgeon's hand. One of the problems of interest in the use of metallic biomaterials is their resistance to corrosion. The clinical significance of the degradation of metal implants has been the purpose of the second method; the interaction between human body and metal components is critical to understand how and why they arrive to corrosion. The percentage of damage in the joints of the prosthetic components has been calculated via high resolution photos and the software ImageJ. The 40% and 50% of the area appeared to have scratches or multiple lines due to mechanical artifacts. The third method of analysis has been made through the use of electron microscopy to quantify the wear surface in polyethylene components. Different joint movements correspond to different mechanisms of damage, which were imprinted in the parts of polyethylene examined. The most affected area was located mainly in the side edges. The results could help the manufacturers to modify the design of the prostheses and thus reduce the number of explants. It could also help surgeons in choosing the model of the prosthesis to be implanted in the patient.
