Cobre e zinco no material percolado e no solo com a aplicação de água residuaria de suinocultura em solo cultivado com soja

O objetivo deste trabalho foi avaliar possíveis efeitos da aplicação de taxas de água residuária de suinocultura (ARS), quanto às concentrações de cobre e zinco, tanto no solo quanto na água percolada de lisímetros de drenagem, durante o ciclo da cultura da soja. O experimento foi conduzido em ambiente protegido, onde havia 24 lisímetros de drenagem. Semeou-se soja cultivar CD 202, e foram aplicadas ARS nas seguintes dosagens: 0; 100; 200 e 300 m³ ha-1 no ciclo, combinadas com duas adubações na semeadura (com e sem adição da adubação recomendada na semeadura), em três repetições por tratamento. Foram feitas seis coletas do material percolado durante o ciclo da cultura e realizadas determinações de cobre e zinco. No solo, foram feitas três coletas em cada parcela experimental, para a determinação do pH, da matéria orgânica, da capacidade de troca catiônica, do cobre e do zinco. O delineamento foi em blocos casualizados, num esquema fatorial de 4 x 2. Observou-se que o cobre no solo não apresentou diferenças significativas com a aplicação de ARS e adubação, enquanto as concentrações de zinco no solo foram influenciadas pelas taxas aplicadas de ARS. As transferências de cobre e de zinco por percolação foram pouco expressivas.

O poético alinhave de Murilo Mendes: o poeta, a musa e a metapoesia em As Metamorfoses

Lying under the contribution of a display of characteristics with multiple meanings (Catholicism, Surrealism, unite of contraries, and the dialogue with other types of art), Murilo Mendes focalizes some subjects that are made to become appealing in his works. Some of these subjects appear in his 1945’s poetry book, As metamorfoses, the object of analysis in this present work: the poet’s figure, insert in the historical view of the World War II and by the poet devastated; the muse’s figure, carrier of the sacred and the profane, whose body represents a repository of descriptions with surrealistic meanings, that is shown indistinctly as the poetry itself; and, concluding, the poetry (or the metapoetry) expressed in this context (historical and literary). Therefore, we intend to search, based in the analysis of poems, how each of this instances are configured inside the poetic universe of Murilo Mendes, with the intention of enlighten the constitution of the sewing made of them by the poet from Juiz de Fora; instances that are very precious when we deal with the poetry that gives to his writings the patent feature of modernity.

A method for retrieving endodontic or atypical non-endodontic separated instruments from the root canal: a report of two cases

Aim: This clinical report presents a new method for retrieving separated instruments from the root canal with minimally invasive procedures. Background: The presence of separated instrument in root canal may interfere in the endodontic treatment prognosis. There are several recommended methods to retrieve separated instruments, but some are difficult in clinically practice. Case report: This study describes two cases of separated instrument removal from the root canal using a stainless-steel prepared needle associated with a K-file. Case 1 presented a fractured gutta-percha condenser within the mandibular second premolar, it was separated during incorrect intracanal medication calcium hydroxide placement. Case 2 had a fractured sewing needle within the upper central incisor that the patient used to remove food debris from the root canal. After cervical preparation, the fractured instruments were fitted inside a prepared needle and then an endodontic instrument (#25 K-file) was adapted with clockwise turning motion between the needle inner wall and the fragment. Conclusion: The endodontic or atypical nonendodontic separated instrument may be easily pull on of the root canal using a single and low cost device. Clinical significance: The methods for retrieving separated instruments from root canal are difficult and destructive procedures. The present case describes a simple method to solve this problem.

Estudo comparativo in vitro da resistência à remoção de grampos circunferenciais aplicados sobre dentes íntegros e restaurados com resina composta

An experimental study was undertaken in arder to find out lhe behavior of the required force to yield dislodgement of circumierential clasps of removable partial dentures ou two groups of samples. 1 with retentive terminais engaging and acting ou enamel 2 with retentive terminais engaging on enamel and acting on composite resm With this aim a device was designed based on a sewing machine (brand name Elgin) that could repeatedly simulate lhe introduction-removal movement of circunferencial clasps ou the samples. ln addiction the device had a platform to sustain the samples and permit measurements, a cycle counter and a dynamometer. The samples were constructed by inclusion in dental stone of extracted natural molar teeth whose retentive areas were ou natural enamel or composite resin addictions.The clasps were fabricated from wax ups of resin and wax and were cast with chromium cobalt alloy. The composite resin used was one of the last generation, monomodal type, photopolymerized and binded to the enamel by the acid etching technique. Tests were carried out in aqueous enviroment. Is was established a maximum of 5.000 cycles for each of the samples. Observatins were made from 100 to 100 cycles until 2.000 and from 200 to 200 cycles to 5.000. Results showed that variations in the amount of the required force for dislodgement of the clasps from the samples during the test periods had no significancy eather to those with retentive areas on the enamel or to those with retentive fabricated with addictions of composite resin

América latina transterritorial: percursos em fronteiras fluidas

Contemporary artists have proposed repositioning of the view as a psicogeographics, routes of drifts, affectives maps, subverting the physical, historical, political and social places in the global mapping. The Chilean artist Eugenio Dittborn with their "Airmail Paintings" that design, sewing, painting and collage are folded and placed in an envelope and sent by post. At your destination, the paint is removed from the envelope, unfolded and hung leaving the marks of the route traveled. The Argentine artist Alicia Herrero in his work "The trip Revoluvionário - title inspired by the trip that Ernesto Guevara held in South America, traveled by navigable rivers of South America and composed the work in the form of a" novel navigated "where each chapter is a port route. As the river of Heraclitus, the writing of "novel navigated" composes processes transposing borders.
