Aim

The aim of this study is to compare the shear bond strengths of conventional resin cement and self-adhesive resin cement bonded to lithium disilicate.

Materials and methods

A total of 40 extracted human molar teeth were mounted in self-cure acrylic resin. Teeth were prepared to obtain flat occlusal surface. About 40 lithium disilicate specimens of dimension—10 mm in diameter and thickness of 2 mm—were fabricated using lost wax technique. The samples were divided into four groups: Groups I, II, III, and IV (n = 10). The specimens were surface treated with Monobond S silane coupling agent. Self-etching primer and bonding agent were applied on the bonding surface of the teeth in groups I and III. The specimens were bonded to the primed teeth with the Multilink N resin cement and subjected to the universal testing machine. The specimens were light-cured. Specimens in groups II and IV were luted to teeth using self-adhesive cement RelyX U100. The same force was applied over the specimen as mentioned above. Excess cement was removed, and light curing was done. The specimens in groups III and IV were subjected to thermocycling for 10,000 cycles at temperatures altering between 5°C and 55°C.

Results

The shear bond strengths of conventional resin cement and self-adhesive resin cement with lithium disilicate were tested before and after thermocycling. Results indicated thermocycling has no significant effect on the bond strengths of conventional or self-adhesive resin cement. However, from the study, it is seen that conventional resin cement had a higher shear bond strength value than the self-adhesive resin cement.

Conclusion

There was a significant difference between the average shear bond strength values of conventional resin cement (Multilink N) and self-adhesive resin cement (RelyX U100) when bonded to lithium disilicate disks, and thermocycling had no significant effect on the bond strength of conventional or self-adhesive resin cements.

Clinical significance

Among all-ceramic systems available, lithium disilicate materials have emerged as an excellent esthetic material for fabrication of anterior and posterior crowns and three-unit anterior fixed partial dentures because of their high translucency and improved optical properties. For successful clinical outcomes, the luting agent should have high bond strength not only to the ceramic surface, but also to the tooth surface.

Published: October 2017

Background

Orthodontic treatment is one of the commonly used dental treatments. Orthodontic forces act on the bone by modulating the biomolecules, chiefly the osteoprotegerin (OPG), osteopontin (OPN), receptor activator of nuclear factor kappa-B (RANK), and RANK ligand (RANKL) (OPG ligand). Hormonal changes are known to cause marked alteration in the levels of these biomolecules. Hence, we planned this study to evaluate the response of bone biomarkers in the gingival crevicular fluid (GCF) in postmenopausal women undergoing fixed orthodontic therapy.

Materials and methods

This study included assessment of 50 subjects who underwent orthodontic treatment from June 2012 to July 2016. All the patients were divided into two study groups with 25 patients in each group: premenopausal group and postmenopausal group. Similar orthodontic wires were used for controlling the forces applied in subjects of both the study groups and their GCF levels of RANKL, and OPN was assessed at baseline and 24 hours after the activation of orthodontic forces. All the results were compiled, assessed, and analyzed by Statistical Package for the Social Sciences software version 16.0. Chi-square test, Student's t-test, and Mann–Whitney U test were used for the assessment of the level of significance.

Results

The mean values of RANKL and OPN in the premenopausal and postmenopausal groups were found to be 241.52 and 317.15 pg/µL respectively. The mean values of RANKL at baseline in the premenopausal and postmenopausal groups were found to be 7.15 and 3.84 pg/µL respectively. Nonsignificant results were obtained while comparing mean OPN and RANKL level alteration in between the two study groups.

Conclusion

The mean alterations in the GCF levels of bone biomarkers are similar for both premenopausal and postmenopausal women.

Clinical significance

For women with either premenopausal or postmenopausal status, orthodontic treatment appears to be equally safer.

DIREITOS DE PROPRIEDADE E INSTRUMENTOS ECONÔMICOS DE REGULAÇÃO AMBIENTAL: UMA ANÁLISE DAS ATRIBUIÇÕES IMPLÍCITAS
Authors: Santos Laura Meneghel dos , Porto Antônio José Maristrello , Sampaio Rômulo Silveira da Rocha
Published: October 2017

Considerando que a sobre-exploração dos recursos naturais está, muitas vezes, associada a falta ou insegurança de direitos de propriedade sobre recursos, bens e serviços que beneficiam a sociedade como um todo, esse trabalho aborda o tratamento dessa problemática pelos instrumentos econômicos de gestão e regulação ambiental. Com base no referencial analítico de Direitos de Propriedade proposto nos trabalhos de Elinor Ostrom, Guido Calabresi e Douglas Melamed, foram analisados três instrumentos econômicos de gestão ambiental (tributação, sistemas de certificados negociáveis e pagamentos por serviços ambientais), assim como uma experiência brasileira de cada um deles

Observamos que ao tentar estabelecer um sistema econômico mais eficiente e sustentável via internalização de externalidade ambientais, os instrumentos econômicos de gestão ambiental engendram uma variedade de formas de atribuição tácitas de direitos de propriedade relativos ao meio ambiente.

Ou seja, para que resultados eficientes (tanto ambientalmente quanto economicamente) possam ser de fato gerados, é essencial que o Direito atue no sentido de garantir a segurança jurídica dessas atribuições, formalizando arranjos institucionais claros e impondo sanções efetivas para aqueles que não forem complacentes com a modelagem jurídica e econômica estabelecida para os instrumentos. Fica claro, portanto, que uma política ambiental eficaz não pode prescindir de um tratamento multidisciplinar que se aproprie das ciências jurídica e econômica.
A FUNÇÃO URBANÍSTICA DO REGISTRO DE IMÓVEIS NA INSCRIÇÃO DE CONSTRUÇÕES
Authors: Carmona Paulo Afonso Cavichioli , Loures de Oliveira Fernanda
Published: October 2017

A análise da legislação pátria denota que, ao longo do processo de construção do sistema de registro predial e com a afirmação do direito urbanístico como disciplina jurídica determinante para o desenvolvimento nacional, delineou-se, no Brasil, uma função urbanística do registro de imóveis. Essa função, de natureza preventiva e indireta, tem papel fundamental para obrigar o proprietário a respeitar os índices e determinações urbanísticas, sob pena de não ter êxito na inscrição de sua construção na serventia imobiliária. Entretanto, tomou corpo, com a edição da Lei 13.465 de 11 de julho de 2017, um questionável movimento destinado a suprimir o papel urbanístico do registro de imóveis, em clara afronta ao imperativo de ordenação das cidades. É o que se visa demonstrar por meio do presente artigo, que se vale de metodologia essencialmente dogmática, pela análise da legislação brasileira. As conclusões obtidas são no sentido da necessidade da manutenção do registro de imóveis como sentinela do direito urbanístico, em prol da afirmação de cidades organizadas. A originalidade do estudo decorre do caráter recente do normativo questionado, avaliando-se seus possíveis efeitos práticos sobre a organização do território urbano – principal ambiente de vida da população brasileira.
PERSPECTIVAS SOBRE A RELAÇÃO URBANO-RURAL: REPERCUSSÕES JURÍDICAS NO IMÓVEL AGRÁRIO APÓS A EDIÇÃO DA LEI N. 13.465/2017

Published: October 2017

Este trabalho analisa a definição do imóvel agrário a partir de um aporte teórico-jurisprudencial objetivando formular considerações sobre qual regime jurídico de tributação e parcelamento a que ele está submetido após a edição da Lei Federal n. 13.465/2017. O processo metodológico foi a análise qualitativa a respeito da distinção entre os espaços urbanos e rurais, das definições e classificações do imóvel agrário, da incidência do Imposto Predial e Territorial Urbano e do Imposto sobre Propriedade Territorial Rural, bem como é discutido o regime de parcelamento do solo. Em um segundo momento, com base no método do caso americano, é feita uma análise jurisprudencial em sequência cronológica de decisões do Supremo Tribunal Federal, do Superior Tribunal de Justiça e dos Tribunais Regionais Federais sobre o tema. Verificou-se que, majoritariamente, a jurisprudência tem entendido que ao imóvel agrário localizado em área urbana se submete à incidência do Imposto sobre Propriedade Territorial Rural, o que reflete tanto em questões propriamente agrárias quanto tributárias envolvendo esta espécie de imóvel. Contudo, as recentes alterações legislativas modificaram parcialmente a primazia da legislação agrária sobre a urbanística nos casos de regularização fundiária de núcleos urbanos informais para fins de parcelamento do uso do solo. O artigo versa sobre tema de grande relevância prática e aborda a temática de forma inédita, em razão da recente edição do novo marco de regularização fundiária urbana no país.

Ao descrever a evolução histórica dos Direitos da criança e do adolescente no Brasil, o presente artigo objetiva analisar o tratamento a eles conferido pelo Estado em distintas épocas, assim como verificar o processo de desenvolvimento e aperfeiçoamento legal do sistema jurídico, mormente se considerarmos as influências de políticas para a cidadania e direitos humanos. Nesse sentido, primeiramente, apresentamos o histórico do tratamento até o século XIX, período caracterizado pela insignificância das crianças e adolescentes. Em seguida, uma análise do incremento da tutela estatal por considerá-los seres imperfeitos. Finalmente, discutimos as principais mudanças desse sistema ao dotá-los de subjetividade jurídica, detentores de direitos e garantias fundamentais. A intenção, por fim, é demonstrar a responsabilidade da família, sociedade e Estado, articulando-se a discussão entre normas jurídicas e políticas públicas a fim de evidenciar as ações que materializam os direitos preconizados pelo Estatuto da Criança e do Adolescente, tendentes, portanto, à proteção integral desse público.
ACERCA DA SEGURANÇA JURÍDICA E DA UNIFORMIDADE DAS DECISÕES A PARTIR DO NOVO CÓDIGO DE PROCESSO CIVIL À LUZ DO MODELO CONSTITUCIONAL DO PROCESSO BRASILEIRO

Published: October 2017

O presente estudo pretende analisar os pressupostos teóricos subjacentes à compreensão da nova codificação processual brasileira, a Lei 13.105/15, a partir da reconstrução dos argumentos centrais presentes na sua Exposição de Motivos, objetivando confrontar referidos pressupostos em face das exigências democráticas estabelecidas pela CF/1988, adotando como referencial teórico as Teorias Discursiva do Direito, de Jürgen Habermas, do Modelo Constitucional do Processo, de Andolina e Vignera, e a do Processo de Elio Fazzalari. A pesquisa, do tipo qualitativa, adotou como procedimento a análise documental e a revisão bibliográfica, e como método de inferência, o indutivo. Com relação aos resultados, a reconstrução dos argumentos centrais da Exposição de Motivos possibilitou identificar uma assimilação entre os conceitos de segurança jurídica e uniformidade de decisões, e seu emprego como forma de justificar as alterações introduzidas pela legislação novel. No entanto, tal entendimento apresenta-se destoante dos requisitos democráticos relativos ao exercício da jurisdição, segundo o Modelo Constitucional Processual brasileiro. Segundo este, a jurisdição não deve ser compreendida de forma meramente instrumental, mas como função estatal garantidora de direitos fundamentais, inclusive com relação ao procedimento que viabiliza o seu exercício, devendo ser capaz de assegurar decisões adequadas à singularidade de cada caso, e ao mesmo tempo coerentes com as decisões proferidas pelos demais órgãos do Poder Judiciário. Conclui-se que a pretensão de substituir a lógica da coerência subjacente a uma racionalidade discursiva pela lógica da eficiência-celeridade-segurança importa na desconsideração do caráter democrático-participativo conformador do Modelo Constitucional Processual brasileiro.
Historical black carbon deposition in the Canadian High Arctic:
A 190-year long ice-core record from Devon Island
Authors: Zdanowicz Christian M. , Proemse Bernadette C. , Edwards Ross , Feiteng Wang , Hogan Chad M. , Kinnard Christophe
Published: October 2017

Abstract. Black carbon aerosol (BC) emitted from natural and anthropogenic sources (e.g., wildfires, coal burning) can contribute to magnify climate warming at high latitudes by darkening snow- and ice-covered surfaces, thus lowering their albedo. Modeling the atmospheric transport and deposition of BC to the Arctic is therefore important, and historical archives of BC accumulation in polar ice can help to validate such modeling efforts. Here we present a 190-year ice-core record of refractory BC (rBC) deposition on Devon ice cap, Canada, spanning calendar years 1810–1990, the first such record ever developed from the Canadian Arctic. The estimated mean deposition flux of rBC on Devon ice cap for 1963–1990 is 0.2 mg m−2 a−1, which is low compared to most Greenland ice-core sites over the same period. The Devon ice cap rBC record also differs from existing Greenland records in that it shows no evidence of a substantial increase in rBC deposition during the early-mid 20th century, which, for Greenland, has been attributed to mid-latitude coal burning emissions. The deposition of other contaminants such as sulfate and Pb increased on Devon ice cap in the 20th century but without a concomitant rise in rBC. Part of the difference with Greenland may be due to local factors such as wind scouring of winter snow at the coring site on Devon ice cap. Air back-trajectory analyses also suggest that Devon ice cap receives BC from more distant North American and Eurasian sources than Greenland, and aerosol mixing and removal during long-range transport over the Arctic Ocean likely masks some of the specific BC source-receptor relationships. Findings from this study underscore the large variability in BC aerosol deposition across the Arctic region that may arise from different transport patterns. This variability needs to be accounted for when estimating the large-scale albedo lowering effect of BC deposition on Arctic snow/ice.
Beaver dam influences on streamflow hydraulic properties and thermal regimes
Authors: Majerova Milada , Neilson Bethany T. , Roper Brett B.
Published: October 2017

Abstract. Beaver dams alter channel hydraulics which in turn change the geomorphic templates of streams. Variability in geomorphic units, the building blocks of stream systems, and water temperature, critical to stream ecological function, define habitat heterogeneity and availability. While prior research has shown the impact of beaver dams on stream hydraulics, geomorphic template, or temperature, the connections or feedbacks between these habitat measures are not well understood. This has left questions regarding relationships between temperature variability at different spatial scales to hydraulic properties such as flow depth and velocity that are dependent on the geomorphology. We combine detailed predicted hydraulic properties, field based maps with an additional classification scheme of geomorphic units, and detailed water temperature observations throughout a study reach to demonstrate the relationship between these factors at different spatial scales (reach, beaver dam complexes, and geomorphic units). Over a three week, low flow period we found temperature to vary 2 °C between the upstream and downstream extents of the reach with a net warming of 1 °C during the day and a net cooling of 0.5 °C at night. At the beaver dam complex scale, net warming of 1.15 °C occurred during the day with variable cooling at night. Regardless of limited temperature changes at these larger scales, the temperaure variability in a beaver dam complex reached up to 10.5 °C due to the diversity of geomorphic units within the complex. At the geomorphic unit scale, the highly altered flow velocity and depth distributions within primary units provide an explanation of the temperature variability within the dam complex. Riffles, with the greatest velocity variability and least depth variability, have the smallest temperature variability and range. The lowest velocity variability occurred within margins, pools, and backwaters which exhibit the widest temperature ranges, but range from shallow to deep. Overall, the predicted flow hydraulic properties for different geomorphic units suggest that velocity is the primary factor in determining the variability of water temperature. However, water depth can also play a role as it impacts warming patterns and can dictate thermal stratification. These findings begin to link key attributes of different geomorphic units to thermal variability and illustrates the value of the geomorphic variability associated with the development of beaver dam complexes.
Global synthesis of forest cover effects on long-term water balance partitioning in large basins
Authors: Mercado-Bettín Daniel , Salazar Juan F. , Villegas Juan Camilo
Published: October 2017

Abstract. Global changes in forest cover have been related to major scientific and social challenges. There are important uncertainties about the potential effects of ongoing forest loss on continental water balances. Here we present an observation-based analysis of long-term water balance partitioning (precipitation divided into evaporation and runoff) in 22 large basins of the world, whereby we identify two partitioning patterns likely related to biophysical mechanisms that depend on the presence and abundance of forests. In less forested basins, evaporation dominates water balance and, as forest cover increases, this dominance of evaporation over runoff is reduced. When forest is the predominant cover, both components account for nearly half of precipitation in the long-term water balance. The distinction between these two patterns is not fully explained by differences between water- and energy-limited environments, but requires consideration of other biophysical properties that affect precipitation and its conversion into evaporation and runoff. Our results indicate that forest cover is an effective descriptor of basin attributes that are relevant for characterizing long-term water balance partitioning in large basins of the world. Further, our results provide insights to understanding and predicting the potential consequences of forest loss on continental water availability, a critical determinant for multiple ecological and societal processes.
Role of NAO and ENSO in the anomalous precipitation in the southern part of China – study on the two contrary high impact weather and climate cases
Authors: Wu Qiuxia
Published: October 2017

Abstract. Their economic and social importance emphasized by the survey of Department of Disaster Relief, Ministry of Civil Affairs of the People’s Republic of China, two different typical patterns of precipitation anomaly in the southern part of China during the 1982/1983 and 2009/2010 cold seasons coincided with the canonical El Niño and positive North Atlantic Oscillation (NAO) and with the El Niño Modoki and negative NAO, respectively. A better understanding of how a particular type of El Niño and a specific phase of NAO worked together to cause the relevant anomalous atmospheric circulation over the East Asia in the two high impact weather and climate cases was an interesting issue and could improve the prediction skill of natural hazards to a certain extent. In conclusion, superimposing on the remote and local Rossby wave responses in the atmosphere induced by the El Niño Modoki-related condensational heat sink over the South China Sea, the downstream extension of the negative NAO was well established by a NAO-induced stationary Rossby wave train along the Asian subtropical jet and played a major role in the persistent dry conditions in the Southwest China for the 2009/2010 boreal winter. On the contrary, for the 1982/1983 boreal winter, the canonical El Niño weakened the downstream extension of the positive NAO, and induced by the canonical El Niño-related condensational heat sink over the western equatorial Pacific Ocean, the remote and local Rossby wave responses in the atmosphere played a leading role in the sustained wet conditions in the South China.
Macrosintaxis y lingüística pragmática
Authors: Fuentes Rodríguez Catalina
Published: October 2017

Las construcciones lingüísticas de ámbito mayor a la oración se analizan con modelos dependientes de la estructura de esta, o bien desde los actos de habla, olvidando, y en ocasiones cuestionando, la existencia de una sintaxis. En este trabajo queremos exponer una alternativa metodológica. Defendemos la existencia de la sintaxis de unidades superiores a la oración (macrosintaxis), lo que conlleva el estudio del enunciado, su estructura, las relaciones que contrae con otros y las unidades superiores en las que se integra, tanto en la lengua hablada como en la escrita. La metodología de análisis, desde nuestro punto de vista, debe integrar la visión componencial con un enfoque pragmático, ya que estamos hablando de comunicaciones realizadas, en un contexto y en un entorno interactivo. La presencia de todos estos elementos se codifica en unidades específicas del discurso así como en estructuras y funciones. Aplicaremos el modelo de Lingüística pragmática ya expuesto en Fuentes Rodríguez (2000) y mostraremos cómo este modelo puede dar cuenta de muchos de los problemas planteados en la sintaxis de los niveles superiores y proporciona instrumentos y criterios suficientes para el avance de la investigación.
Estudio macrosintáctico de las estructuras que introducen la fuente enunciativa: como…/ según…/ para…/en palabras de…/ en opinión de
Authors: López Martín José Manuel
Published: October 2017

La denominada “gramática tradicional” difícilmente puede dar respuesta al funcionamiento de una serie de estructuras que aparecen normalmente en el margen oracional, van entre pausas, y ejercen la función de introducir la fuente informativa de lo dicho. Nos referimos a expresiones introducidas por según, como dice, en palabras de, para o en opinión de. Este tipo de estructuras, no fijadas y con movilidad oracional, pueden especializarse en presentar al responsable último de lo dicho (complemento de la aserción), o bien marcar simplemente al dicente (complemento locutivo). Por ello, necesitamos un enfoque pragmático, supraoracional y más cercano a la teoría de los denominados “evidenciales” (Dendale y Tasmowski 2001, Aikhenvald 2003, Willet 1988) para explicar las similitudes y diferencias morfo-funcionales de esta serie de complementos de la enunciación que poseen, además, una gran rentabilidad desde el punto de vista argumentativo. Nuestro estudio se propone, por tanto, realizar una descripción minuciosa de este tipo de construcciones, ya sea desde un punto de vista sintáctico (función, movilidad, posibilidad de combinarse con otros complementos “marginales”, capacidad para aparecer insertos dentro de subordinadas), estructural (posibilidad de introducir sintagmas u oraciones) o enunciativo (capacidad para introducir al locutor/enunciador), con la finalidad de, en la medida de lo posible, poner algo de orden dentro del poco sistematizado (por haber sido poco estudiado de una manera metodológicamente homogénea) campo de la sintaxis supraoracional.
The Language of Police Reports: A Quest for Precision or a Bureaucratic Exercise of Language Degradation
Authors: Ćetković Sanja
Published: October 2017

The language of the members of law enforcement has been widely studied mostly in terms of investigating various aspects of police interview discourse. However, our aim here is to examine the language of police reports as a sample of written language of the police outside the context of police-suspect encounters and to describe some of its distinctive linguistic features which function as more or less effective means for achieving maximum clarity and precision. An intimate relationship between the language of legal documents and the language of police reports has been established with respect to style and specific language choices that characterize both registers. Nevertheless, we have observed some peculiar features of police written language that seem to be originating from a compelling need to be as accurate and all-inclusive as possible and to fully conform to conventional standards of report writing.
Las perífrasis verbales de infinitivo. Dificultades morfosintácticas y semánticas para los universitarios taiwaneses
Authors: 林娟娟 Chuan-Chuan Lin
Published: October 2017

La conjugación de los verbos siempre genera problemas caóticos para los estudiantes taiwaneses de español, ya que dicha categoría gramatical no lleva función significativa en términos morfológicos en chino. El nivel de dificultad de este estudio, las perífrasis verbales, va aún más allá. La complejidad de las construcciones perifrásticas en español es abrumadora para los aprendices taiwaneses, debido a la gran cantidad de ellas, ya que estas perífrasis verbales pueden ser de tres tipos: de infinitivo, gerundio y participio. Por ese motivo, en este estudio nos centramos en el primer grupo, a saber, el formado por un verbo auxiliar que total o parcialmente pierde el significado primitivo, la presencia o no de un nexo intercalado (preposición/conjunción) y por un infinitivo con significado pleno. Además de estudiar este tipo de construcciones, abordaremos el problema de su aprendizaje. Los alumnos, a la hora de ponerse en contacto con el conjunto de perífrasis verbales, han de familiarizarse con el orden sintáctico y, además, han de distinguir el valor semántico de cada una, pese a que el matiz entre una y otra es muy pequeño y aparezca la problemática morfológica o morfosintáctica. El hecho de que las estructuras perifrásticas, semifrásticas y no perifrásticas provoquen casos de ambigüedad, les hace a los alumnos aún más costoso el aprendizaje. Conviene poner de manifiesto la clasificación perifrástica de los verbos de modo más analítico y exhaustivo, desde el punto de vista lingüístico en español por una parte, y, por otra parte, es imprescindible mejorar la interpretación del significado buscando la equivalencia conceptual entre la lengua meta y la lengua materna. Cuanto más difícil es la comprensión de las perífrasis verbales de infinitivo en español, más esfuerzos se necesitan en la docencia y en el aprendizaje. Dominando las propiedades de estas perífrasis y los conceptos equivalentes en chino, se favorecerá el resultado del aprendizaje por parte del alumnado.

DO POEMA À CANÇÃO: O LIRISMO COLOQUIAL EM CASTIGO PRO COMBOIO MALANDRO, DE ANTÓNIO JACINTO
Authors: SILVA Marta De Oliveira Fróis da , BATTISTA Elisabeth
Published: October 2017

Em um contexto de resistência, em 1948, em Angola ainda sob a égide do regime colonial, vários escritores se uniram para se opor ao contexto opressor da colonização por meio do Movimento dos Novos Intelectuais de Angola – o MNIA, tendo como lema o brado “Vamos descobrir Angola”. Entre eles estava António Jacinto e a defesa pela redescoberta da nacionalidade africana com uma identidade angolana própria. António Jacinto escreve o poema “Castigo pro Comboio Malandro” (1961), apresentando na forma e no conteúdo a musicalidade realçando a resistência ao contexto histórico vigente. Através do ritmo, oralidade, musicalidade e de figuras de linguagem o poeta capta os ritmos africanos por meio das pausas intensas e do uso do Kimbundo, língua africana mesclada ao português. Importante ressaltar que este poema foi musicado por Fausto Bordalo Dias em 1974, de forma que os versos de António Jacinto são, constantemente, revisitados pela/na memória do povo angolano.
IDENTIFICAÇÃO DE PERFIS LINGUÍSTICOS NO FACEBOOK DURANTE A INVESTIGAÇÃO POLICIAL
Authors: TIMBANE Alexandre António
Published: October 2017

A linguística é uma ciência importante para a nossa sociedade e pode ser aproveitada nos diversos campos do interesse da nossa sociedade. Sendo assim, a presente pesquisa é uma reflexão sobre a investigação criminal com o uso do facebook como ferramenta para a identificação do perfil linguístico dos suspeitos. Segundo Coulthard (1985) a análise do discurso é, sem dúvidas, um meio pelo qual se observa e se analisa a língua com maior incidência na interação conversacional em textos orais e escritos. A pesquisa tem por objetivo (a) discutir os conceitos da oralidade e da escrita em contexto do facebook; (b) explicar como o discurso da internet tem características próprias e (c) delimitar as características dos suspeitos investigados com base em exemplos de quatro indivíduos. A pesquisa analisou quatro usuários de facebook, todos moçambicanos e observou que a oralidade se mistura no escrito, mas o contrário não ocorre, quer dizer, podemos ver marcas da oralidade num texto escrito, mas no texto oral a escrita não se apresenta de forma evidente. Cada usuário do facebook tem o seu estilo conversacional que se demonstra através do léxico, da construção sintática bem como o uso de estrangeirismos e de moçambicanismos. No facebook, o respeito pela norma ortográfica tem pouca importância e assim, o uso de abreviaturas, siglas e outros neologismos são aceites pelos usuários. Conclui-se que o facebook é um aliado importante que pode ajudar aos policiais na identificação do perfil linguístico dos suspeitos.

Published: October 2017

We describe the case of a 52-year-old woman with scleritis caused by an imipenem-resistant strain of Nocardia beijingensis. The patient presented with pain, redness, and nodules on the sclera of 8 weeks’ duration. A Gram stain from a nodule on the superonasal aspect of the globe was initially negative. After empiric treatment for an autoimmune etiology, cytopathology confirmed filamentous bacteria. A presumptive diagnosis of Nocardia scleritis was made, and medical management was based on a literature review on treatments for Nocardia infections. Cultures returned confirming Nocardia beijingensis. Antibiotic sensitivity testing confirmed the correct initial management. The patient’s scleritis resolved with a good visual outcome.

Ultrasound biomicroscopy (UBM) is a valuable diagnostic modality for imaging anterior ocular structures. Its utility has been well studied in anterior segment, lenticular, and pars plicata pathologies. However, imaging of the pars plana has been seldom described. We present the case of a 66-year-old woman referred for vitreous hemorrhage after expulsive cannula dislodgement into the posterior segment during wound hydration at the end of cataract surgery. B-scan ultrasonography initially detected a very anterior abnormality, but the resolution was insufficient for accurate diagnosis. Subsequent UBM clearly showed rupture of the pars plana and a mild cyclodialysis cleft. To our knowledge, this is the first report of a pars plana rupture detected by ultrasound, which expands the diagnostic capacities and indications for UBM.
Femtosecond laser–assisted cataract surgery in vitrectomized eye with posterior chamber phakic intraocular lens
Authors: Anisimova Natalia , Malyugin Boris , Arbisser Lisa B. , Sobolev Nikolay

We describe a case of femtosecond laser–assisted cataract surgery (FLACS) in an eye with multiple comorbidities, including retinal detachment surgery, high myopia, posterior chamber phakic intraocular lens (PC pIOL) and residual, emulsified, silicone oil located in the anterior chamber. FLACS was affected by the optical blockage, but the incomplete capsular tear was recoverable. The case suggests that silicone oil bubbles concentrated at the dome of the posterior corneal surface, along with the PC pIOL optic edges and scars after corneal astigmatic relaxing incisions can lead to incomplete anterior capsulotomy.
Long-Term Performance of Electrodes Based on Vinyl Acetate Homo-Polymer Binder

Published: October 2017

In this work we propose the use of a hydro-dispersible polymer such as the poly vinyl acetate as a binder for the production of electrodes for lithium-ion batteries. To increase the film forming properties of the polymer the poly vinyl was added with triacetin that acts as a plasticizer. The electrochemical stability of the polymer was tested by a polarizing electrode, formed by mixing the polymer with carbon. Subsequently, an electrode tape was prepared by using LiNi0.5Mn1.5O4 as the active material and characterized by SEM, EDS and TGA. Lithium metal cells were assembled and tested to evaluate specific capacity, power and energy density at various discharge rates. The cycle life of the cell was evaluated by galvanostatic charge/discharge cycles. The tests showed that the electrodes prepared with PVA plasticized with triacetin have very good electrochemical performance in terms of capacity retention as a function of the discharge rate and the cycle number. Our work demonstrates that the use of triacetin to plasticize the PVA allows to increase the electrochemical stability of the electrode likely due to an improvement of the slurry filmability. The proposed method could represent a promising technology for the production of long-term performance lithium batteries.
Preparation and In Vitro Drug Release Behavior of 1,10-Phenanthroline/β-cyclodextrin–poly (Glycidyl Methacrylate) Drug-Loaded Microspheres
Authors: Li Ya , Zhen Weijun
Published: October 2017

In this study, novel star-shaped polymers of β-cyclodextrin (β-CD)–poly (glycidyl methacrylate) (PGMA) were prepared by atom transfer radical polymerization (ATRP), formed from GMA and β-CD. In addition, the structure, properties and hydrophilicity of the β-CD-PGMA polymers thus prepared were systematically analyzed. 1,10-phenanthroline monohydrate (Phen)/β-CD-PGMA drug-loaded microspheres were prepared by emulsion solvent evaporation. The optimum preparation conditions were determined by orthogonal tests. Analysis results indicated that the performance of star-shaped polymers of β-CD-PGMA clearly changes, resulting in the increase of the contact angle from 17° to 72.5°, and their thermal degradation temperature was enhanced from 260 °C to 401 °C. Moreover, β-CD-PGMA drug-loaded microspheres with a smooth, spherical surface were successfully prepared, and the drug-loading capacity and average particle size of drug-loaded microspheres were 26.67 % and 10 μm, respectively. Drug release tests indicated that the release behavior of β-CD-PGMA drug-loaded microspheres conformed to Higuchi release kinetics, which exhibited a significant drug delivery capability. The release rate and utilization of β-CD-PGMA were greater than that of β-CD, demonstrating that β-CD-PGMA was more suitable as a drug delivery material.
Generalized Layerings for Arbitrary and Fixed Drawing Areas
Authors: Rüegg Ulf , Ehlers Thorsten , Spönemann Miro , Von Hanxleden Reinhard
Published: October 2017

The Directed Layering Problem (DLP) solves a step of the
widely used layer-based approach to automatically
draw directed acyclic graphs. To cater for cyclic graphs,
usually a preprocessing step is used that solves
the Feedback Arc Set Problem (FASP) to make the graph acyclic before
a layering is determined.

Here we present the Generalized Layering Problem (GLP),
which solves the combination of DLP and FASP simultaneously,
allowing general graphs as input.
We present an integer programming model
and a heuristic to solve the NP-complete GLP and perform
thorough evaluations on different sets of graphs and with
different implementations for the steps of the layer-based approach.
We observe that GLP reduces the number of
dummy nodes significantly, can produce more compact drawings, and
improves on graphs where DLP yields poor aspect ratios.

The drawings resulting from GLP also turn out
to be more suitable
for making the best possible use of a given drawing area.
However, we show that a specialized variant of GLP
can yield considerable improvements
w.r.t. this particular optimization goal.
Node Overlap Removal by Growing a Tree
Authors: Nachmanson Lev , Nocaj Arlind , Bereg Sergey , Zhang Leishi , Holroyd Alexander
Published: October 2017

Node overlap removal is a necessary step in many scenarios
including laying out a graph, or visualizing a tag cloud. Our
contribution is a new overlap removal algorithm that iteratively
builds a Minimum Spanning Tree on a Delaunay triangulation of the
node centers and removes the node overlaps by "growing" the
tree. The algorithm is simple to implement, yet it produces high
quality layouts. According to our experiments it runs several
times faster than the current state-of-the-art methods.
Non-aligned Drawings of Planar Graphs
Authors: Biedl Therese , Pennarun Claire
Published: October 2017

A non-aligned drawing of a graph is a drawing
where no two vertices are in the same row or column.
Auber et al. showed that not all planar graphs
have a non-aligned planar straight-line drawing in the $n\times n$-grid.
They also showed that such a drawing exists if up to $n-3$ edges may have a bend.

In this paper, we give algorithms for non-aligned planar drawings
that improve on the results by Auber et al. In particular, we
give such drawings on an $n\times n$-grid with
at most $\frac{2n-5}{3}$ bends, and we study what grid-size can be
achieved if we insist on having straight-line drawings.
A Direct Proof of the Strong Hanani-Tutte Theorem on the Projective Plane

Published: October 2017

We reprove the strong Hanani-Tutte theorem on the projective plane.
In contrast to the previous proof by Pelsmajer, Schaefer and Stasi,
our method is constructive and
does not rely on the characterization of forbidden minors,
which gives hope to extend it to other surfaces.
« Seuls les marxistes aiment le passé » : le tiers-mondisme de Pier Paolo Pasolini dans le genre des appunti
Authors: Caminati Luca , Saglier Viviane
Published: October 2017

Pasolini conçoit en 1968 un projet de film intitulé Notes pour un poème sur le tiers-monde (Appunti per un poema sul Terzo Mondo), constitué d’une série de courts et de moyens métrages en forme de « notes » mêlant fiction et documentaire. Comme d’autres expérimentations avant-gardistes de l’époque, le genre des appunti que pratique Pasolini se situe à l’intersection de différentes formes filmiques, dont le documentaire ethnographique autoréflexif, le récit de voyage expérimental et l’essai cinématographique. Pour Pasolini, aller tourner dans le tiers-monde représente un moyen d’explorer le projet politique du mouvement des pays non alignés issu de la conférence de Bandung et le désir de l’artiste engagé de trouver dans les luttes de libération un espace de changement politique radical, une révolution da farsi. La forme essayiste, ouverte, des appunti de Pasolini vise précisément à reproduire dans sa propre structure hybride l’ouverture du mouvement révolutionnaire.
Du développement du capitalisme à l’infini plan-séquence : les quatre « utopies » de Porno-Teo-Kolossal
Authors: Paquette Julie
Published: October 2017

Cet article analyse le traitement d’un film jamais réalisé de Pier Paolo Pasolini, Porno-Teo-Kolossal. Il se propose de montrer que les quatre mondes qu’y traversent les deux protagonistes peuvent être compris comme des variations sur la modalité de l’utopie, à savoir l’utopie, la dystopie, l’uchronie et l’atopie ; les trois premiers moments correspondent à la mise en récit de la conscience d’une Europe en voie d’homologation et en butte aux pouvoirs autoritaires et fascistes, alors que le quatrième moment correspond à ce que Pasolini entrevoyait comme une potentialité venue du Sud. Ce parcours doit être considéré comme étant « révolutionnaire », non pas au sens téléologique du terme, mais plutôt au sens du mot latin revolutio, qui signifie « retour à l’origine ». Cette lecture de Porno-Teo-Kolossal permettra de faire entendre une conception de l’engagement qui serait basée sur un infini plan-séquence irréductible à l’opération du montage-mort.
Disturbing the Peace of “Two Not So Very Different” Countries: James Baldwin and Fritz Raddatz
Authors: Zocco Gianna
Published: October 2017

When James Baldwin in No Name in the Street discusses the case of Tony Maynard, who had
been imprisoned in Hamburg in 1967, he emphasizes that his efforts to aid his unjustly
imprisoned friend were greatly supported by his German publishing house Rowohlt and, in
particular, by his then-editor Fritz Raddatz (1931–2015). While the passages on Maynard
remain the only instance in Baldwin’s published writings in which Raddatz—praised as a
courageous “anti-Nazi German” and a kindred ally who “knows what it means to be beaten in
prison”—is mentioned directly, the relation between Baldwin and Raddatz has left traces
that cover over fifty years. The African-American writer and Rowohlt’s chief editor got to
know each other around 1963, when Baldwin was first published in Germany. They exchanged
letters between 1965 and 1984, and many of Raddatz’s critical writings from different
periods—the first piece from 1965, the last from 2014—focus of Baldwin’s books. They also
collaborated on various projects—among them a long interview and Baldwin’s review of
Roots—which were all published in the German weekly newspaper Die Zeit, where Raddatz
served as head of the literary and arts sections from 1977 to 1985. Drawing on published
and unpublished writings of both men, this article provides a discussion of the most
significant facets of this under-explored relationship and its literary achievements.
Thereby, it sheds new light on two central questions of recent Baldwin scholarship: first,
the circumstances of production and formation crucial to Baldwin’s writings of the 1970s
and 1980s, and secondly, Baldwin’s international activities, his transcultural
reception and influence.
