Combinação de técnicas para tratamento cirúrgico de fratura do complexo zigomático-maxilar: relato de caso

The zygomatic-maxillary complex due to its projection framed as one of the areas hardest hit by injuries, as well as the nasal bones. Component important in this context, the zygomatic arch fracture is under the direct action of forces due to its structure fragile, resulting in loss of normal convex curvature. Therefore, it is aimed to report a clinical case of male patient, who had leucoderma zygomatic bone fracture using access transcutaneous and intra-oral fracture reduction body of zygoma and zygomatic arch. In addition to evidence combination of closed and open techniques for solving the case. The technique provided the patient excellent cosmetic and functional results.

Tratamento conservador de fratura de arco zigomátio: uma visão conservadora

Introduction: The zygomatic maxillary complex is the second most affected area of the face due to injuries, surpassed only by the nasal bones. The zygomatic arch fracture is under the direct action of trauma (punch, head butt), its fragile structure, losing its normal convex curvature in the temporal area. Objective: To report a case, using a reduction technique of zygomatic arch fracture using a hook or Ginestet Barros. Case report: A male patient, 25 years of age, leukoderma, showing zygomatic arch fracture right. The patient underwent closed reduction with the hook adapted to the skin. The patient was instructed to keep care of the region for at least four weeks

Análise do chute de bola parada em indivíduos não praticantes de futebol

In the soccer game, the player needs to be ready to attend the outlined requirements in differents extrategic moments. The fundamentals of soccer optimize their participation in a game, however, a correct execution of the movements can ensure their efficiency. From those fundamentals, we highlight the kick executed with the lower limbs characterized mainly by being an appeal of offensive played moving or stopped. Therefore, the objective of this review was to evaluate the kick's ability in the non- practitioners of this modality. Through a descripitive search, the objective followed by the protocol proposed by Mor-Cristian in 1979 was reached. The sample consisted of 48 individuals from both sexes, aged between 19 and 43 years old, students of Physics’ Education of a private University in the State of São Paulo - Brazil. The average of target 01 was 15.92 points, target 02 was 3.83, target 03 showed an average of 4.75 points and the target 04 had the average of 10.33. From the results we can observe that the target 01 have received the highest score over the other arcs. We conclude that the lower arches shown to be more likely to hit compared to the upper arches as being individuals who do not practice soccer.

Flutter analysis including structural uncertainties

The common practice in industry is to perform flutter analyses considering the generalized stiffness and mass matrices obtained from finite element method (FEM) and aerodynamic generalized force matrices obtained from a panel method, as the doublet lattice method. These analyses are often reperformed if significant differences are found in structural frequencies and damping ratios determined from ground vibration tests compared to FEM. This unavoidable rework can result in a lengthy and costly process of analysis during the aircraft development. In this context, this paper presents an approach to perform flutter analysis including uncertainties in natural frequencies and damping ratios. The main goal is to assure the nominal system’s stability considering these modal parameters varying in a limited range. The aeroelastic system is written as an affine parameter model and the robust stability is verified solving a Lyapunov function through linear matrix inequalities and convex optimization

Usinagem do alumínio da classe 6005 com uso de ferramenta cerâmica

The machining process is so much important in the economic world. Many machining parameters have been studied to maximize results, in terms of cost and lifetime. (decrease of cutting tool wear, improved surface finish, among others). The objective of this study is to evaluate the wear of a ceramic tool in the machining of the aluminum alloy 6005 A. The analysis of the wear of the cutting tools is very important due to its big impact on the final finishing of the piece as a whole. The evaluation took place in two stages, first it was done a detailed study of the literature of the whole machining process, where the study of the formation and swarf classification were among the most important steps in this phase. The second step consisted in the machining of the piece of aluminum 6005 A with a ceramic cutting tool constituded of aluminum oxide and magnesium oxide with silicon carbide impregnation. The swarf generated in this process was then photographed with a Zeiss optical microscope and analyzed for its size and shape. Through this comparison it was concluded that the swarf are generated shear swarfs, shaped like a tangled, fragmented and arcs connected, thus classifying the material as medium difficulty machining. Through the image analysis tool it was concluded that the parameter of lower wear was the: Vc = 500m / min, f = 0.10mm / rev and ap = 0.5mm

A Porpoise, Australophocaena dioptrica, Previously Identified As Phocoena spinipinnis, From Heard Island

Guiler, Burton and Gales (1987) reported a cranium (Tasmanian Museum No. A141 1) they identified as belonging to Burmeister’s porpoise, Phocoena spinipinnis Burmeister, 1865 from Heard Island (53°S 73°30’E). They noted that P. spinipinnis was previously known only from the cold-temperate coastal waters of South America and claimed that this cranium was evidence that the species has a much wider distribution than previously known. We have examined the photographs and details of their specimen and re-identify it here as Australophocaena dioptrica (Lahille, 1912) (family Phocoenidae). Barnes (1985) listed several features that distinguish the skulls of species within the subfamily Phocoenoidinae (including A. dioptrica) from those species within the Phocoeninae (including Phocoena spp.). Features that distinguish A. dioptrica from P. spinipinnis, dearly visible in the published photographs of the cranium from Heard Island, include: a relatively small, oval-shaped temporal fossa; an elevated, high-vaulted braincase that slopes abruptly onto the narial region; relatively large, high and convex premaxillary bosses; dorso-ventrally expanded zygomatic process of the squamosal; short and antetoposteriorly expanded postorbital process of the fronds; and maxillae extendmg nearly to the dorsal margin of the supraoccipital on the top of the skull. In all these features, the Heard Island specimen conforms with those of A. dioptrica. Crania of A. dioptrica have been illustrated by Hamilton (1941), Norris and McFarland (1958), Brownell (1975), Fordyce et al. (1984), and Barnes (1985). Crania of P. spinipinnis have been illustrated by Norris and McFarland (1958) and Brownell and Praderi (1984).
