Massa paranasal: dacrioestenose congênita? Relato de caso

O objetivo deste é descrever uma criança portadora de massa paranasal, atentando para a importância dos diagnósticos diferenciais. RELATO do CASO: ACS, 6 meses, sexo feminino, desde o nascimento apresentando abaulamento não inflamatório, no canto medial do olho esquerdo, lacrimejamento e hiperemia no olho direito. Ao exame apresentava fenômeno de Bell negativo bilateral, lagoftalmo à direita, ulceração e opacidade corneana à direita; presença de lesão arredondada, de superfície lisa no canto medial do olho esquerdo, sem sinais inflamatórios, medindo aproximadamente 2 cm de diâmetro, não pulsátil. À palpação, a lesão era elevada, de consistência fibroelástica, imóvel, indolor, irredutível. À propedêutica das vias lacrimais, não havia refluxo à compressão, o teste de Milder foi negativo em ambos olhos e as vias apresentavam-se pérvias à dacriocistografia. O exame tomográfico revelou tratar-se de meningocele fronto-etmoidal. COMENTÁRIOS: Os autores chamam a atenção para a adequada semiologia para a investigação das massas paranasais, a fim de se instituir o adequado tratamento.

Old archetype rides into Bell's hell [Review]

BILLED as a trip to hell, Bell Shakespeare and Queensland Theatre Company's production of Faustus is adapted from Christopher Marlowe's Doctor Faustus and Johann Wolfgang von Goethe's fragmentary Urfaust, an early version of Goethe's enormous two-volume Faust tragedy published in 1808, then in full in 1832

Experience has no shadow : Bell tower III

I created Experience Has No Shadow (2010) following a successful Ausdance Qld choreographic grant in 2010, which comprised of two solos and a video-dance at the Performance Space at the Judith Wright Centre. The aim of the Bell Tower III residency was to research and construct a Stage One Development that explored choreographic approaches to oral histories. Like many first generation Australians, oral histories are the way memories and experiences of distant homelands often offer the only connection to cultural origins. Consequently, I drew on auto-ethnographic references in the form of family stories – specifically those of my mother’s family - told and retold by my mother and her family as East German refugees during World War II. While working on the video, I explored a way to make a direct connection to the past stories by using a recording of my mother’s voice. She is re-telling a favourite story about Salamo the circus horse that was sold to my great grandfather as a work horse. Rather than representing the text literally, I attempted to capture the intensity of the storytelling which accompanied abstract footage of Avril Huddy filmed through perspex glass producing animal-like shapes that continually blur and morph in and out of focus. Strangely, by tying the story in with the filmed images a whole new story seems to emerge. Two distinct solos were created in collaboration with the performers, Expressions Dance Company’s Elise May and QUT’s Avril Huddy. These were performed at the Judith Wright Centre for Contemporary Arts, Performance Space, 1st April, 2010. The simplicity of its design became a key concept behind the work in terms of sets, spacing requirements, and costumes – almost minimalist. The choreographic process was conceived as highly collaborative, with commissioned music (and eventually lighting features) to act as equal partners in the performance.

Non-destructive discrimination of Bell states by NMR using a single ancilla qubit

Discrimination of Bell states plays an important role in a number of quantum computational protocols such as teleportation and secret sharing. However, most of the protocols dealing with Bell state discrimination in the literature either involve performing correlated measurements or destroying the entanglement of the system. Here, we demonstrate an NMR-based experimental realization of a protocol for Bell state discrimination, following a scheme proposed by Gupta et al (quant-ph/0504183v1, 23 April 2005), which does not destroy the Bell state under consideration. Using the proposed protocol, one can deterministically distinguish the Bell states, without performing a measurement using the entangled basis. State discrimination is performed through two independent measurements on one ancilla qubit, which leaves the Bell states unchanged.

Theoretical and experimental studies of the bell-jar-top inductively coupled plasma

The present paper describes a systematic study of argon plasmas in a bell-jar inductively coupled plasma (ICP) source over the range of pressure 5-20 mtorr and power input 0.2-0.5 kW, Experimental measurements as well as results of numerical simulations are presented. The models used in the study include the well-known global balance model (or the global model) as well as a detailed two-dimensional (2-D) fluid model of the system, The global model is able to provide reasonably accurate values for the global electron temperature and plasma density, The 2-D model provides spatial distributions of various plasma parameters that make it possible to compare with data measured in the experiments, The experimental measurements were obtained using a tuned Langmuir double-probe technique to reduce the RF interference and obtain the light versus current (I-V) characteristics of the probe. Time-averaged electron temperature and plasma density were measured for various combinations of pressure and applied RF power, The predictions of the 2-D model were found to be in good qualitative agreement with measured data, It was found that the electron temperature distribution T-e was more or less uniform in the chamber, It was also seen that the electron temperature depends primarily on pressure, but is almost independent of the power input, except in the very low-pressure regime. The plasma density goes up almost linearly with the power input.

Two-dimensional fluid model simulation of bell jar top inductively coupled plasma

In the present paper, argon (Ar) plasmas in a bell jar inductively coupled plasma (ICP) source are systematically studied over pressures from 5 to 20 mtorr and power inputs from 0.2 to 0.5 kW. In this study, both a two-dimensional (2-D) fluid model simulation and global model calculation are compared, The 2-D fluid model simulation with a self-consistent power deposition is developed to describe the Ar plasma behavior as well as predict the plasma parameter distributions, Finally, a quantitative comparison between the global model and the fluid model is made to test their validity.
