Avaliação da usinagem do INCONEL 718

The nickel superalloys are known as being a material with poor machinability, they have some properties like high hardness, good resistance at high temperature, tendency to weld with the tool material at high temperature, etc. In the aerospace, biomedical and petrochemical industry, are increasing the need to use materials that resist to aggressive process and environment. In these uses, it has increased the use of nickel-based superalloys like Inconel 718 and consequently the need to research new techniques and tools to improve the machinability of this material. For the superalloys and resistant alloys at high temperatures is considered that the difficulty in the machining regards to the combination of the relatively high cutting forces and high temperatures that grow during the machine process, causing deformation or breakage of the cutting tool. This work purpose is to develop the study of the machining of external cylindrical turning of the nickel based alloy Inconel 718, using ceramic tools, seeking the optimization of machining this alloy, looking to provide real productive increases without the need of investments in new production means. The machining test were accomplished using commercials hard metal tools and the results were compared each other to find the best tool and the best parameter. The conclusion is that the tool TNMG160408-23 -class 1005- was the better one, when used with the parameter 60_15_08

Fragmento d'alma

Fragmento D' Alma is an artistic research that part of a poetic tale through an initial charge of dawn one fantastic universe where words have life and willingly. The work includes sculptural works in order to interpret through the use of allegory situations of the tale in the form of sculptural compositions considering one or more characters in the story. In the sculptural work, I tried figuring the relations tale as my interpretations and poetic, so I sought theoretical studies of allegory after noting my affinity with the theme to contribute to the relationship text and image set in my work. I also sought to understand the relationships that the text played with sculptural work, so the chances that I could address this through dialogue between text and image. The studies collected through surveys pointed allegory by João Adolfo Hansen, as well as in various artistic and visual references present in my repertoire, such as the Baroque sculpture of Bernini, the performances of Berna Reale and literature of Neil Gaiman, contributed in this research to the development of my creative process during the preparation of this research work of art, making the complexity of the relationship between textual production and poetic sculptural three-dimensional, also became a concern and an integral theme of my work and my reflections presented here. Therefore, I conclude based on my own experience in this work, the artistic research inspired allegory might contribute to the development of my creative process during the preparation of this artwork, besides assigning relations between textual production and poetic dimensional sculpture

Mapeamento geológico e petrologia dos complexos máfico-ultramáficos de Mangabal Sul e Mangabal Norte, região de Sanclerlândia, Goiás

The Mangabal Sul and Mangabal Norte mafic-ultramafic complexes are interpreted as intrusive stratiform bodies in the Goiás Magmatic Arc during the Brazilian cycle, being economically important for harboring significant amounts of nickel and copper sulfides. The main lithotypes of the complexes are gabbronorites, olivine gabbronorites, pyroxenites and peridotites, with variated degrees of deformation, recrystallization and metamorphism superimposed, with metamorphic peak of amphibolite to granulite facies evidenced mainly by the occurrence of coronitic olivine in metamafic rocks and the occurrence of syn-kinematic retrometamorphism associated with the development of the main foliation Sn. The Sn foliation planes show NE-SW preferential direction, consistent with the foliation direction of VIII the enclosing gneisses and schists, also concordant with the general elongation of mafic and ultramafic bodies displayed on map. The sulfide phase presents textures that indicate remobilization, associated with the occurrence of significant amounts of rutile within the ore which reinforces this idea. Along with the sulfides, the occurrence of expressive quantities of titanium oxides such as ilmenite and rutile, make the area more economically attractive. It can be suggested that the Mangabal Norte and Mangabal Sul complexes are contemporary, have the same genetic affinity and suffered the same deformational and metamorphic processes, evidenced by their structural and petrological similarities

Os recursos publicitários como ferramenta de valorização do fazer-jornalístico: um estudo das capas da Revista Veja

This study focuses on an analysis of the convergence of Journalism and Publicity on the covers of the magazine. This paper aims to clarify how the dynamics of that relationship, understanding that in contemporary society, both Journalism and Publicity to perform the same function-to inform, differing only in the objective-journalism sells news, Publicity sells dream. The magazine Veja was chosen for this study because its importance and scope in publishing. Inspired by Time magazine, founded in 1922 by Henry Luce, Veja was the 2nd review of gender information in Brazil. Today a record run of more than 1 million copies, occupying the 3rd position in the ranking of news magazines sold over the world and the largest weekly magazine of the U.S. Among the media, the magazine is the most identified with the publicity, because as disseminator of advertising, the magazine has the advantage of being able to achieve precisely the widest range of public and the possibility of dealing with many different subjects; In addition, the number of people who have contact with the advertising is much greater because, on average, four people read each issue and is also common that the same reader review the revised more than once, which helps in setting the message advertising. This affinity between magazine and publicity is in its essence as both are prepared for the market, seek to promote, show themselves to be bought. Accordingly, we intend to find out how media discourse of Veja and publicity, approach in the writing of magazine covers

Efeitos da interação entre o uso de doses suprafarmacológicas de decanoato de nandrolona e do exercício físico sobre a próstata de ratos adultos

Os hormônios esteróides anabólico-androgênicos (EAA) compreendem a testosterona e seus derivados. Atletas e não atletas interessados em aumentar o desempenho esportivo, a força, a aparência física e a massa muscular têm utilizado esteróides anabólico-androgênicos sintéticos (EAAs) sem indicação médica. O uso de EAAs pode causar câncer de próstata, doença coronariana e esterilidade. No presente trabalho, avaliou-se os efeitos de altas doses de decanoato de nandrolona, do exercício físico resistido e da interação desses fatores sobre os lobos prostáticos de ratos machos adultos. Vinte ratos foram divididos aleatoriamente em quatro grupos experimentais e tratados e pesados por oito semanas: Esteróide + Exercício (EE), Sedentário + Esteróide (ES), Veículo + Exercício (VE) e Veículo + Sedentário (VS). Eles receberam injeção i.m de decanoato de nandrolona (5mg/Kg) e veículo (propilenoglicol) (0,2 mL/Kg). O peso absoluto corpóreo e do lobo ventral da próstata foi aferido. Os lobos prostáticos foram coletados, dissecados e processados, empregando-se técnicas microscópicas (histológicas, histoquímicas e imunohistoquímicas) e morfométricas. Os dados foram analisados por ANOVA bifatorial e Tukey (p<0,05). Alterações estatisticamente significativas nas massas corpórea, do lobo ventral, no índice de proliferação celular, na população de células basais e na análise dos volumes relativos dos componentes prostáticos (epitélio, estroma e lúmen) foram observadas. O decanoato de nandrolona determinou o aumento da proliferação celular, sugerindo o desenvolvimento da hiperplasia hormonal. De modo geral, as respostas não foram homogêneas para os parâmetros analisados, visto que os tecidos apresentam níveis de expressão de receptores de andrógenos, afinidade de ligação e vias metabólicas de conversão...

Diversidade genética em Staphylococcus aureus resistentes à oxacilina em isolados de pacientes pediátricos do Hospital das Clínicas de Botucatu

Staphylococcus aureus é um patógeno ubíquo capaz de causar uma variedade de infecções em humanos. A resistência desse microrganismo a antibióticos como oxacilina e meticilina é um problema sério, de crescimento significativo para a terapêutica antimicrobiana clínica em pacientes acometidos por infecções estafilocócicas. A resistência à meticilina em S. aureus é decorrente da alteração do sítio de ação dos antibióticos β-lactâmicos, os quais agem através da inibição de enzimas que catalisam a síntese da parede celular. Essas enzimas são o sítio de ação das penicilinas, e por isso, passaram a ser chamadas de proteínas ligadoras de penicilinas (PBPs). O gene mecA codifica a PBP2a, que substitui a função das outras PBPs neste patógeno e confere resistência a β-lactâmicos. A PBP2a exibe uma afinidade reduzida pelo anel β-lactâmico e permite que a bactéria continue a sintetizar a parede bacteriana. Este gene faz parte de um elemento genético móvel encontrado em isolados de MRSA, designado cassete cromossômico estafilocócico mec (SCCmec), integrado ao cromossomo de S. aureus. O objetivo do estudo foi a caracterização molecular de 139 isolados de S.aureus provenientes de pacientes pediátricos com bacteremia durante o período de 1991 a 2010. Métodos moleculares foram utilizados para a determinação do perfil genético das amostras, incluindo, identificação do tipo de SCCmec, detecção do gene codificador de leucocidina de panton valentine (PVL) e similaridade clonal em gel de eletroforese em campo pulsado (PFGE). O gene mecA foi detectado em 32 (23%) amostras e houve predomínio do SCCmec IV (68,8%) em relação ao SCCmec III (31,2%). A presença de PVL foi encontrada em 18 amostras (12,9%), todas sensíveis à oxacilina. O clone epidêmico brasileiro, relacionado ao SCCmec tipo III, esteve presente na unidade neonatal do hospital...

O passado no presente: João Gilberto Noll, leitor de Álvares de Azevedo

In the mid-nineteenth century, in his fruitful years of the perhaps best-known shortest literary career, Álvares de Azevedo wrote this verse “As ondas são anjos que dormem no mar” (“The waves are angels who sleep in the sea”). In the presentation of João Gilberto Noll’s young adult novel Anjo das ondas (Angel of the waves) in 2010, Ivan Marques states that the character in the novel, Gustavo, “with his adolescent passion, and torn spirit with overflowing lyrics, could even be compared to our tropical Byron”. João Gilberto Noll establishes a connection between him and Álvares de Azevedo that invites the reader to go beyond a first reading level of his work, seeking evidence of dialogue ratification between two apparently distant writers. The subtle intertextuality exceeds the initial clue and can be detected on Noll’s theme development from the history of Gustavo, a troubled teenager in search of his identity. Noll’s affinity to Álvares de Azevedo can still be captured in his narrative texture, in voices coming from his text; however, they also reveal to be unique and original features of his literary production. An apparent exercise in style shows that each author fulfills his mission by expressing, in his own way, the feeling of his time. In addition, it shows that through aesthetic emotion, literature allows us to transcend time and space.
