Morfometria dos forames mandibular, mentual e infraorbital de Lobo-guará Chrysocyon brachyurus, Illiger, 1815 aplicada a bloqueios anestésicos

CHAPTER II - The Chrysocyon brachyurus is the biggest South American canid which has a high frequency of dental injuries, both in wild and captivity. Thus, veterinary procedures are necessary to preserve the feeding capacity of hundreds of captive specimens worldwide. The aim of this study was to study the mandibular morphometry of maned wolf with emphasis on the establishment of anatomic references to the anesthetic blockage of the inferior alveolar and mental nerves. Therefore, 15 measurements in 22 hemimandibles of C. brachyurus adults were taken. For extra-oral technique of blockage of the inferior alveolar nerve at the level of the mandibular foramen, it is stated that the needle should be advanced, close to the medial surface of the mandibular ramus, by 11.4 mm perpendiculary from the palpable concavity. Alternatively, the needle can be introduced for 30.4 mm from the angular process at 20-25 degrees angle with the ventral margin. For blocking only the mentual nerve, it is recommended the introduction of needle for 10 mm, close to the lateral aspect of the mandibular body, at the level of the lower first premolar. The mandibular foramen showed similars position, size and symmetry in the maned wolfs specimens examined. The comparison of the data with those available for other carnivores reflects the necessity for determining these anatomical references specifically for each species.

Avaliação da soldagem GMAW mecanizada e automatizada para união de dutos utilizando fontes convencional e com controle de curto- circuito

Welding is one of the most employed process for joining steel pipes. Although, manual welding is still the most used one, mechanized version and even automatized one have increased its demand. Thus, this work deals with girth welding of API 5L X65 pipes with 8” of nominal diameter and 8.0 mm thickness, beveled with V-30º narrow gap. Torch is moved by a bug carrier (mechanized welding) and further the parameters are controlled as a function of angular position (automatized welding). Welding parameters are presented for filling the joint with two-passes (root and filling/capping passes). Parameters for the root pass were extracted from previous author´s work with weldments carried out in plates, but validated in this work for pipe welding. GMAW processes were assessed with short-circuit metal transfer in both conventional and derivative modes using different technologies (RMD, STT and CMT). After the parameter determination, mechanical testing was performed for welding qualification (uniaxial tension, face and root bending, nick break, Charpy V-notch impact, microhardness and macrograph). The initially obtained results for RMD and CMT were acceptable for all testing and, in a second moment, also for the STT. However, weld beads carried out by using the conventional process failed and revealed the existence of lack of fusion, which required further parametrization. Thus, a Parameter-Variation System for Girth Welding (SVP) was designed and built to allow varying the welding parameters as a function of angular position by using an inclinometer. The parameters were set for each of the three angular positions (flat, vertical downhill and overhead). By using such equipment and approach, the conventional process with parameter variation allowed reducing the welding time for joint accomplishment of the order of 38% for the root pass and 30% for the filling/capping pass.

Antonio Carlos Viana e as escritas do erotismo em Aberto está o inferno

A presente dissertação objetiva estabelecer uma interface entre os estudos da linguagem performática na literatura e os estudos sobre o erotismo a partir da obra do escritor sergipano Antonio Carlos Viana. Trazendo à tona o lado violento e traumático de experiências sexuais, são nela analisados os contos “As meninas do coronel”, “Mal-assado” e “In Memoriam”, pelo viés da prostituição, do casamento e da morte, respectivamente. Observa-se que, ao optar pela escrita sobre o corpo e pela problematização do erotismo vinculada a uma perspectiva nauseante do sexo, desvinculada da ideia de prazer, Viana performatiza, de acordo com os pressupostos do novo realismo, experiências afetivas marcadas pela dor. Para investigar os procedimentos de linguagem utilizados por Viana, com o intuito de desvendar os enigmas que perpassam o universo emocional e labiríntico de personagens devastados por sentimentos que mesclam corrupção, poder, morte e erotismo, recorro aos estudos sobre o caráter performático e grotesco da linguagem no novo realismo – em especial ao pensamento de Karl Erik Schøllhammer e Mikhail Bakhtin –, sobre a relação entre morte e erotismo – a partir das considerações de George Bataille, Octavio Paz e Philippe Ariès – e sobre as nuances da sexualidade e suas revoluções – mediante o pensamento de Anthony Giddens.
