Abstrait Dans l’iconographie chrétienne, le dragon est généralement associé au mal et se trouve représenté vaincu par le Christ, saint Georges, d’autres saints ou des figures bibliques. Au Moyen-Âge, il figure aussi sur des chapiteaux, dans les marges des manuscrits ou dans les blasons de familles et d’ordres militaires. Le dragon, parfois, est dépourvu de son sens négatif et investi d’un sens positif. La présente étude vise à identifier l’image du dragon dans le contexte luso-brésilien entre les XVIe et XIXe siècles. Il s’agit en particulier d’examiner la relation entre le dragon comme symbole du mal et le sens qu’il prend quand il est associé au pouvoir impérial brésilien. On envisagera le déplacement entre la dévotion à saint Georges, liée à la dynastie d’Avis, et l’image du dragon dans l’héraldique de la maison et dynastie de Bragance. Les images de trois codex seront examinées: le Livro do Armeiro-Mor (Livre de l’Armurier–majeur), un manuscrit enluminé de 1509, le Livro da nobreza (Livre de la noblesse) de 1521 et le Tesouro da Nobreza (Trésor de la Noblesse) de 1675. Ces codex sont conservés à Torre do Tombo à Lisbonne. À titre de comparaison, l’étude recourt aussi à d’autres images, afin d’analyser la survie de la représentation du dragon dans les symboles royaux.

The speciation of the heavy metals Cu, Cr, and Pb in surface sediment samples collected from Lugu Lake in China was analyzed by European Community Bureau of Reference (BCR) sequential extraction methods. Heavy metal bioavailability was assessed by risk assessment code. This study demonstrates that BCR sequential extraction methods and risk assessment code can be used as valuable tools to assess heavy metal mobility, bioavailability and eco-toxicity. The distribution of Cu, Cr, and Pb in the surface sediment of Lugu Lake showed that all three metals were mainly present in the reducible fraction. The bioavailability of the heavy metals in the surface sediment was in the order Cu > Cr > Pb.

The connection of the Unistrut “System 1” double layer grid space frame transfers loads statically indeterminately from a member to the connection plate through two lugs and a bolt. The connection is studied by Finite Element analysis, design code analysis and a series of experimental tests. There is quite good agreement between the analysis methods and fair agreement with the tests. The test series isolates the contributions of the individual load paths showing quite good correspondence. The failure of the lugs in an unpredicted shear mode is the major cause for discrepancies. However, analysis of that shear mode is consistent with the tests.

Los code smells son síntomas en el código fuente que pueden revelar problemas de diseño. Para poder solucionar un smell deben aplicarse un conjunto de refactorings que permitan restructurar el sistema. Sin embargo, al aplicar un conjunto de refactorings en un orden determinado, pueden surgir problemas que impiden que éstos se apliquen. Por ejemplo, porque un refactoring que depende de una reestructuración realizada por otro refactoring que aún no fue aplicado, o porque un refactoring referencia un artefacto del sistema que fue modificado por un refactoring aplicado anteriormente. Por estos motivos, para aplicar un conjunto de refactorings, se deben analizar las dependencias que existen entre estos para poder establecer el orden de aplicación. En esta línea, este trabajo presenta una herramienta que identifica y soluciona los conflictos originados por dependencias entre refactorings para luego aplicar automáticamente los mismos. Los resultados, si bien son preliminares, indican que este enfoque permite identificar y solucionar un alto porcentaje de conflictos.

Cet article traite de la création et de la transformation des signes d'identité à travers les vêtements dans l'Ordre Militaire de Santiago (ou Ordre de Saint Jacques de l'Epée) pendant l'époque qui couvre sa fondation en 1171 jusqu’à la fin du Moyen âge. Dans l'introduction l'auteur analyse l'utilisation des couleurs, le genre de vêtements, la forme et les signes emblématiques qui forment les structures de l'identité monastique. Les ordres militaires qui apparaissent au XIIeme siècle, ont hérité de cette tradition monastique et l'utilisent pour établir leur identité de moine-soldat. Les fondateurs de l'ordre de Santiago -un groupe de chevaliers- marquent leur conversion religieuse en adoptant une croix rouge en forme d'épée sur la poitrine, et en renonçant à arborer des couleurs voyantes et des tissus précieux. Mais leur code, qui se manifeste à travers les vêtements, change vers la fin du Moyen-âge en accord avec la transformation du sens que prend le fait d’être membre de l'Ordre. La dernière partie de l'article tente d'interpréter ces changements, en analysant à la fois le règlement du Chapitre Général de Santiago et les sources littéraires en relation avec l'Ordre.

Ab initio density functional calculations were performed on a toroidal carbon C120 nanostructure with a single beryllium atom bonded to its outer surface. These calculations are based on DFT with the generalized gradient approximation PW91 (Perdew and Wang) as implemented in the Materials Studio v.4.3 code. The Dmol3 module was used to calculate, among others, total energy, charge density, HOMO-LUMO and Mulliken population analysis. On the basis of these results, the beryllium-coated toroidal carbon C120 nanostructure appears to be a good candidate for H2 storage with moderate adsorption energy.

O objeto de estudo deste trabalho está focado em encontrar as marcas enunciativas da categoria da melancolia, conforme proposta pela Teoria Psicanalítica freudiana, na narrativa dos contos do escritor uruguaio Horacio Quiroga, melancolia que leva à morte, muitas vezes por suicídio. Com efeito, boa parte da narrativa quiroguiana está centrada na temática da morte com suas personagens sucumbindo de maneira trágica e inesperada e diversas vezes sem motivo aparente. Há um “deixar-se morrer” que aparece com notável insistência ao ponto de ser a morte, de mãos dadas com a luta contra a natureza, a temática central da obra do escritor. A leitura aqui abordada pretende mostrar como esses derradeiros atos da vida são originados pela melancolia das personagens, estados de alma melancólicos patológicos causados pela perda do objeto de desejo que não mais se encontra, pelo deslocamento da sombra desse objeto para o eu que, através da ambivalência emocional do binômio amor-ódio, causará essa morte como destino inevitável.
The object of study of this work is focused in finding the enunciation marks of melancholy category, as proposed by Freudian Psychoanalytic Theory, in the narrative of the tales of the Uruguayan writer Horacio Quiroga, melancholy that led to death, sometimes by suicide. Indeed, great part of Quiroguian narrative is centered in the thematic of death with its characters succumbing in a tragic and unexpected way, sometimes with no apparent reasons. There is a “let-to-die” that appears with notorious insistence to the extent of being death, together with the struggle with nature, the central thematic of the author. The reading here approached intends to show how these final acts of life are originated by characters’ melancholy, pathological melancholy moods caused by the loss of the object of desire that no longer is found, by the displacement of the shadow of that object to the ego that, through emotional ambivalence of the love-hate binomial, will cause that death as an inevitable fate.

O solo é um dos maiores reservatórios de biodiversidade microbiana, constituindo um importante recurso para a exploração biotecnológica. Esta biodiversidade não se distribui uniformemente neste ambiente, e a cobertura vegetal exerce grande influência sobre a diversidade microbiana do solo. Este fenômeno é conhecido como efeito rizosfera, onde algumas espécies têm suas populações aumentadas conforme a qualidade e quantidade de material exsudado pelas raízes. Nesse sentido, torna-se interessante o estudo da interação de algumas culturas de importância econômica com bactérias do solo que possam promover seu crescimento. Sendo assim, o objetivo deste trabalho foi avaliar o efeito rizosfera promovido por duas espécies de Solanum, S. lycopersicum (tomate) e S. quitoense (lulo) sobre a comunidade de bactérias diazotróficas em solos sob diferentes tipos de manejo: mata secundária (MS), hortícola convencional (HC) e orgânico (ORG). As bactérias diazotróficas foram isoladas usando meios semi-sólidos livres de nitrogênio (JMV, NFb, JNFb, LGI e LGI-P) e sua população foi quantificada pela técnica do número mais provável (NMP). O posicionamento taxonômico dos isolados foi realizado pelo sequenciamento parcial do gene 16S RNAr, aplicando o índice de Shanon-Wiener para determinar variações na biodiversidade entre os tratamentos. Os isolados foram avaliados para características de promoção do crescimento vegetal, como a capacidade de produção de compostos indólicos, produção de sideróforos e solubilização de fosfatos inorgânicos. Foram obtidos 117 isolados bacterianos em populações acima de 1x104 células g-1 rizosfera ou solo, dos quais 114 foram posicionados taxonomicamente dentro dos seguintes gêneros: Rhizobium (60 isolados); Pseudomonas (15 isolados); Burkholderia (12 isolados); Enterobacter e Variovorax (6 isolados cada); Cupriavidus e Massilia (3 isolados cada); Stenotrophomonas e Roseateles (2 isolados cada); Bacillus, Herbaspirillum, Xanthomonas, Novosphingobium e Caulobacter (um isolado cada). Houve diferença tanto na composição qualitativa como quantitativa da comunidade diazotrófica associada às diferentes espécies de Solanum, com diminuição da diversidade de diazotrofos na rizosfera de S. lycopersicum e S. quitoense em comparação ao solo, e incremento na população de diazotrofos na rizosfera – principalmente de Rhizobium na rizosfera de S. lycopersicum, independentemente do manejo de solo estudado. A caracterização bioquímica identificou a capacidade de produção de compostos indólicos em 54 isolados, a produção de siderofóros em 49 isolados, a capacidade para solubilizar FePO4 foi detectada em 84 isolados e a solubilização de AlPO4 em 49 isolados. Dentre a coleção de isolados obtida, 49% apresentaram potencial aplicação na promoção do crescimento de tomate, onde 32% correspondem a isolados provenientes do solo, 40% da rizosfera de tomate e 28% da rizosfera de lulo.
Soil is one of the largest reservoirs of microbial biodiversity and an important resource for biotechnological exploitation. Such biodiversity is not evenly distributed in this environment, and the plant cover exerts great influence on the soil microbial community composition. This phenomenon is known as rhizosphere effect, inducing some bacterial species to increase their populations according to the quality and quantity of root exudates. In this sense, is important to study the interactions of some economically important crops with soil bacteria that may promote their growth. Thus, the aim of this study was to evaluate the rhizosphere effect promoted by two Solanum species, S. lycopersicum (tomato) and S. quitoense (lulo) on the community of nitrogen fixing-bacteria in soils under different three types of management as secondary forest (SF), conventional horticultural (CH) and organic (ORG). The nitrogen fixing bacteria were isolated using nitrogen-free semi-solid media (JMV NFb, JNFb, LGI and LGI-P) and its population were quantified by the most probable number (MPN) technique. The taxonomic position of isolates was performed by the partial sequencing of the 16S rRNA gene, using the Shannon-Wiener index to determine variations in biodiversity between treatments. The isolates were also characterized for its plant growth-promotion traits, as indole compounds production, siderophores production and solubilization of inorganic phosphates. A total of 117 bacterial isolates in populations above 1x104 cells g-1 of rhizosphere or soil were obtained and taxonomically positioned within the following genera: Rhizobium (60 isolates); Pseudomonas (15 isolates); Burkholderia (12 isolates); Enterobacter and Variovorax (6 isolates each); Cupriavidus and Massilia (3 isolates each); Stenotrophomonas and Roseateles (2 isolates each); Bacillus, Herbaspirillum, Xanthomonas, Novosphingobium and Caulobacter (a single isolate each). Differences in the qualitative and quantitative composition of diazotrophic community associated to different Solanum species were found, with lower diazotroph diversity in the rhizosphere of S. lycopersicum or S. quitoense as compared to soil, although its population size was increased in the rhizosphere of S. lycopersicum - mainly related to Rhizobium isolates, regardless the soil management studied. The biochemical characterization of isolates allowed the identification of 54 isolates with indole compounds production ability, siderophores production ability in 49 isolates, FePO4 solubilization ability was detected in 84 isolates and AlPO4 solubilization was observed in 49 isolates. From the total of isolates obtained, 49% showed potential application as tomato growth-promoters, from which 32% were isolated from soil, 40% from the tomato rhizosphere and 28% from the rhizosphere of lulo.

Il processo di Data Entry manuale non solo è oneroso dal punto di vista temporale ed economico, lo è ancor di più poiché rappresenta una fonte di errore: per questi motivi, l’acquisizione automatizzata delle informazioni lungo la catena produttiva è un obiettivo fortemente desiderato dal Gruppo per migliorare i propri business. Le tecnologie analizzate, ormai diffuse e standardizzate in ampia scala come barcode, etichette logistiche, terminali in radiofrequenza, possono apportare grandi benefici ai processi aziendali, ancor più integrandole su misura agli ERP aziendali, permettendo una registrazione rapida e corretta delle informazioni e la diffusione immediata delle stesse all’intera organizzazione. L’analisi dei processi e dei flussi hanno evidenziato le criticità e permesso di capire dove e quando intervenire con una progettazione che risultasse quanto più la best suite possibile. Il lancio dei fabbisogni, l’entrata, la mappatura e la movimentazione merci in Magazzino, lo stato di produzione, lo scarico componenti ed il carico di produzione in Confezionamento e Semilavorazione, l’istituzione di un magazzino di interscambio Dogana, un flusso di tracciabilità preciso e rapido, sono tutti eventi che modificheranno i processi aziendali, snellendoli e svincolando risorse che potranno essere reinvestite in operatività a valore aggiunto superiore. I risultati potenzialmente ottenibili, comprovati anche dalle esperienze esterne di fornitori e consulenza, hanno generato le condizioni necessarie ad un rapido studio e start dei lavori: il Gruppo è entusiasta ed impaziente di portare a termine quanto prima il progetto e di andare a regime con la nuova modalità operativa, snellita ed ottimizzata.

The continuous evolution of information security threats, coupled with increasing sophistication of malicious codes and the greater flexibility in working practices demanded by organizations and individual users, have imposed further burdens on the development of effective anti-malware defenses. Despite the fact that the IT community is endeavoring to prevent and thwart security threats, the Internet is perceived as the medium that transmits not only legitimate information but also malicious codes. In this cat-and-mouse predicament, it is widely acknowledged that, as new security countermeasures arise, malware authors are always able to learn how to manipulate the loopholes or vulnerabilities of these technologies, and can thereby weaponize new streams of malicious attacks. From e-mail attachments embedded with Trojan horses to recent advanced malware attacks such as Gozi programs, which compromise and transmit users’ highly sensitive information in a clandestine way, malware continues to evolve to be increasingly surreptitious and deadly. This trend of malware development seems foreseeable, yet making it increasingly arduous for organizations and/or individuals to detect and remove malicious codes and to defend against profit-driven perpetrators in the cyber world. This article introduces new malware threats such as ransomware, spyware, and rootkits, discusses the trends of malware development, and provides analysis for malware defenses. Keywords: Ransomware, Spyware, Anti-Virus, Malware, Malicious Code, Background Various forms of malware have been a part of the computing environment since before the implementation of the public Internet. However, the Internet’s ubiquity has ushered in an explosion in the severity and complexity of various forms of malicious applications delivered via increasingly ingenious methods. The original malware attacks were perpetrated via e-mail attachments, but new vulnerabilities have been identified and exploited by a variety of perpetrators who range from merely curious hackers to sophisticated organized criminals and identify thieves. In an earlier manuscript (Luo & Warkentin, 2005), the authors established the basic taxonomy of malware that included various types of computer viruses (boot sector viruses, macro viruses, etc.), worms, and Trojan horses. Since that time, numerous new forms of malicious code have been found “in the wild.”

The compound 2-[2-(4-methylphenylamino)-4-phenylthiazol-5-yl]benzofuran was prepared from 1-(4-methylphenyl)-3-(N-phenylbenzimidoyl)thiourea and 2-(2-bromoacetyl) benzofuran in the presence of triethylamine and characterized by FTIR, NMR, and mass spectra. Density functional theory (DFT) computations were adopted for the geometry optimization of this compound, to evaluate their Mulliken atomic charge distribution, HOMO-LUMO energy gap, and vibrational analysis. The titled compound induced G1 cell cycle arrest, which is regulated by CDK2 in cancer cells. Therefore, we used molecular modeling to study in-silico for the possible inhibitory effect as a mechanism of this compound as anticancer agents (PDB code: 2KW6, 6DL7, 6VJO, 6WMW, and 7LAE). The molecular docking study revealed that the compound was the most effective in inhibiting CDk2 cancer cells.

Anchoring structures, systems and components to concrete is a significant activity in the design and construction of a nuclear power plant. Early in this decade the Concrete Capacity Design method (CCD) was adopted by the American Concrete Institute (ACI) for use in the structural design for both commercial and nuclear facilities. This design method and associated qualification tests brings new challenges to designing efficient means for anchoring to concrete structures. Although the CCD method provides guidance on many aspects of concrete anchorage there are a few areas, pertinent to nuclear power plant construction, that are not covered or require significant interpretation of the most recent codes. This paper will focus on the design of shear lugs used to resist significant lateral loads. Results from laboratory tests of shear lugs are presented. These full scale tests considered the interaction of tension and shear loads on the performance of shear lug assemblies. Recommendations for the efficient use of shear lugs are provided.

This paper presents a critical review of the newly published ASME BTH-1-2005, which is intended to be a companion to ASME B30.20, Below the Hook Lifting Devices, a safety standard. The very limited structural design criteria contained in the latter standard was previously addressed in the literature by the current author and was compared against the various national and international regulations, codes, and standards in regard to the presumed factors of safety inherent in the designs of vessel lifting lugs. Based upon the criteria previously outlined and addressed, the current American National Standard ASME BTH-1-2005 is critically reviewed and the commentary that is now incorporated in such is analyzed in an effort to determine the adequacy of the updates in meeting and exceeding the current regulations in both the United States and Canada. The statutory and provincial regulations in both the United States and the province of Alberta, Canada are also reviewed and discussed with respect to the too often utilized phrase “factor of safety” (FOS). The implied implications derived from the chosen FOS are also outlined. Exemplar lugs on vessels are defined and the finite element analyses and closed form Hertzian contact problem solutions are presented and interpreted in accordance with the new ASME BTH-1-2005 structural design criteria. These results are again highlighted against the very limited design information contained within ASME B30.20. A review of the author’s prior recommendations made to revise the ASME B30.20 Below the Hook Lifting Devices safety standard are presented and discussed in light of the examples and technical justification presented in the following paragraphs. Contact stresses that are well known to exist between a lifting pin and clevis type geometry are also discussed in light of the new structural design criteria contained within ASME BTH-1-2005. Additional recommendations are provided for the design and analysis of vessel lifting lugs in consideration of current regulations.

Unsteady behaviour of a new fluid-beam model for flow in collapsible channels is studied in this paper. A finite element code is developed to solve the fully fluid-structure interaction unsteady problem with method of rotating spines. The self-excited oscillations for different parameters are calculated and compared with these of the earlier fluid-membrane model by Luo & Pedley (1996). A stability line in the tension – wall stiffness space is identified which seems to associate with the small amplitude oscillations which are found only in the new model. As tension is reduced from the stability line, the oscillations undergo a change in amplitude and through to period doubling, highly irregular oscillations with chaotic-like behaviour, and finally divergent. The transition of these different types of oscillations, however, depends on the value of the wall stiffness which is new in this model.
