Rapid Design and Manufacture of Ultralight Cellular Materials

This paper details the design, manufacture and testing of regular metallic lattice structures with unit cell sizes in the range 0.8mm to 5mm and truss elements of 100-500 µm in diameter [1]. The structures were manufactured using Selective Laser Melting (SLM) technology from 316L stainless steel. Compression tests have shown yield loadings of over 3.5kN despite being only 18mm by 18mm by 10mm in height, the results are favourably comparable to current commercially available metallic foams. Software has been developed that creates slice files without the use of CAD software or STL files and is capable of producing lattices within a volume defined by a STL file.Mechanical Engineerin

The perception of the students of the Career of Medicine at University of Buenos Aires on the treatment of abortion in a medical education

El objetivo del siguiente artículo es indagar cómo es el tratamiento del aborto y su atención, en la Carrera de Medicina de la UBA. Para ello, se hará hincapié en tres dimensiones. La primera, consiste en el análisis de los emergentes de la mencionada Carrera a la luz de las legislaciones, y regulaciones que promueven Derechos Sexuales como parte fundamental de los Derechos Humanos (DDHH). La segunda estriba en el análisis de tales emergentes en relación a discontinuidades y rupturas con lo que se definirá como Modelo Médico Hegemónico (MMH). Por último, se indagará en las políticas, representaciones y prácticas respecto al misoprostol. Esta investigación es de carácter cualitativo. El corpus analizado consiste en entrevistas semi-estructuradas a 24 estudiantes de la mencionada Carrera y en regulaciones vigentes emitidas tanto por organismos médicos nacionales, latinoamericanos e internacionales. Como resultados preliminares se destacan, primero, la escasa permeabilidad en la Carrera de las regulaciones vigentes, los conocimientos y actualizaciones farmacológicas expresadas en los documentos emitidos por organismos médicos nacionales, latinoamericanos e internacionales en los últimos 10 años. En segundo lugar, resalta la predominancia de un silencio o vacío en la currícula en relación al aborto. Este silencio no es inocuo, sino que tiene efectos concretos: no garantizar el cumplimiento con el marco de DDHH vigentes en Argentina. Por último, el desconocimiento sobre el misoprostol y su amplia utilidad en el campo gineco-obstétrico refuerza la asimetría en la relación médico/a-paciente y una idea de aborto medicalizado que, por lo tanto, robustece al MMH.The aim of this article is to investigate how the approach to abortion and attention in the Career of Medicine of the UBA. To do this, it will emphasize three dimensions. The first is the analysis of emerging Career in light of the laws and regulations that promote sexual rights as a fundamental part of Human Rights (HR). The second analysis is to emerging regarding such discontinuities and ruptures thereby be defined as Hegemonic Medical Model (MMH). Finally, he will inquire into policies, representations and practices regarding misoprostol. This research is qualitative. The corpus analyzed consists of semi-structured interviews to 24 students mentioned Career and national, Latin American and international medical organizations regulations. As preliminary results stand, first, the low permeability in the Career of the regulations, knowledge and pharmacological updates expressed in documents issued by national medical, Latin American and international agencies the past 10 years. Secondly, it highlights the predominance of silence or void in the curriculum in relation to abortion. This silence is not harmless, but has specific effects: not ensure compliance with the human rights framework in force in Argentina. Finally, ignorance about misoprostol and its broad utility in obstetrics and gynecology field reinforces the asymmetry in the medical / a-patient relationship and a sense of medicalized abortion, therefore, strengthens the MMH.Fil: Mines Cuenya, Ana.

Risk of suicide during treatment with venlafaxine, italopram, fluoxetine, and dothiepin : retrospective cohort study

Objective To compare the risk of suicide in adults usingthe antidepressant venlafaxine compared with citalopram, fluoxetine, and dothiepin. Design Retrospective cohort study. Setting UK General Practice Research Database. Participants 219 088 patients, aged 18-89 years, who were prescribed venlafaxine, citalopram, fluoxetine, or dothiepin from 1995 to 2005. Main outcome measures Completed suicide and attempted suicide. Results Venlafaxine users had a higher burden of risk factors for suicide, includingprevious suicide attempts and proxies for severe depression or depression that was difficult to treat. In the analysis for completed suicides, unadjusted and adjusted hazard ratios for venlafaxine compared with citalopram were 2.44 (95% confidence interval 1.12 to 5.31) and 1.70 (0.76 to 3.80), for venlafaxine compared with fluoxetine were 2.85 (1.37 to 5.94) and 1.63 (0.74 to 3.59), and for venlafaxine compared with dothiepin were 2.54 (1.07 to 6.02) and 1.31 (0.53 to 3.25). Compared with other study drugs, venlafaxine was also associated with an increased risk of attempted suicide, but adjustment for measured confounders substantially reduced the hazard ratios. Conclusions Venlafaxine use was consistently associated with higher risk of suicide compared with citalopram, fluoxetine, and dothiepin. Venlafaxine users had a higher burden of suicide risk factors, however, and adjustment for measured confounders substantially reduced the excess risks. Since the secondary data used in this analysis allowed only indirect and partial measurements of potential confounders, it is possible that residual confounding explains much, if not all, of the observed excess risk

On the measurement of dimensional quality of titanium alloy micro lattice struts manufactured using selective laser melting

The paper describes the measurement of the surface quality, dimensional accuracy, and cross sectional circularity of titanium alloy ( Ti-6Al-4V ) micro struts manufactured using selective laser melting. This quality is related to manufacturing and materials characteristics

Bifurcation analysis of a normal form for excitable media: Are stable dynamical alternans on a ring possible?

We present a bifurcation analysis of a normal form for travelling waves in one-dimensional excitable media. The normal form which has been recently proposed on phenomenological grounds is given in form of a differential delay equation. The normal form exhibits a symmetry preserving Hopf bifurcation which may coalesce with a saddle-node in a Bogdanov-Takens point, and a symmetry breaking spatially inhomogeneous pitchfork bifurcation. We study here the Hopf bifurcation for the propagation of a single pulse in a ring by means of a center manifold reduction, and for a wave train by means of a multiscale analysis leading to a real Ginzburg-Landau equation as the corresponding amplitude equation. Both, the center manifold reduction and the multiscale analysis show that the Hopf bifurcation is always subcritical independent of the parameters. This may have links to cardiac alternans which have so far been believed to be stable oscillations emanating from a supercritical bifurcation. We discuss the implications for cardiac alternans and revisit the instability in some excitable media where the oscillations had been believed to be stable. In particular, we show that our condition for the onset of the Hopf bifurcation coincides with the well known restitution condition for cardiac alternans.Comment: to be published in Chao
