La gimnasia, el embarazo y la maternidad : Ruth Schwarz de Morgenroth, Argentina 1930-1945

La siguiente ponencia analiza la obra y el recorrido personal, institucional y profesional de Ruth Schwarz de Morgenroth. Según Marcela Nari, Ruth fue la primera mujer en "organizar por primera vez ejercicios con mujeres embarazadas dentro de una maternidad en América del sur en los años '30" (Nari, 2004: 175). Si bien la preocupación por la maternidad ya estaba presente en la agenda de las políticas públicas hace décadas; la obra de Ruth ha sido central para consolidar un campo de intervención médico-social. En particular analizaremos algunos de sus escritos realizados a finales de los años '30 y principios de los '40, como, por ejemplo, "Gimnasia para la mujer. Ejercicios durante el embarazo y la edad critica" de 1938, "La gimnasia específicamente femenina" de 1942, "La mujer de '39' y su gimnasia" de 1944 y algunos de sus más de 40 artículos escritos en revistas de divulgación médica como La Semana Médica, Acción Médica, Viva Cien Años, Archivos de la Clínica de Obstetricia y Ginecología Eliseo Cantón, entre otras publicaciones. Centraremos el análisis en la gimnasia como práctica constructora de ciertos sentidos sobre el cuerpo femenino, la feminidad, la sexualidad y la maternidad así como sus resistencias

The ballast pick-up problem. A theoretical approach and two experimental campaigns

The aim of this contribution is to present a theoretical approach and two experimental campaigns (on wind tunnel and on the track) concerning the research work about the ballast train-induced-wind erosion (BTIWE) phenomenon. When a high speed train overpasses the critical speed, it produces a wind speed close to the track large enough to start the motion of the ballast elements, eventually leading to the rolling of the stones (Kwon and Park, 2006) and, if these stones get enough energy, they can jump and then initiate a saltation-like chain reaction, as found in the saltation processes of soil eolian erosion (Bagnold, 1941). The expelled stones can reach a height which is larger than the lowest parts of the train, striking them (and the track surroundings) producing considerable damage that should be avoided. There is not much published work about this phenomenon, in spite of the great interest that exists due to its relevant applications in increasing the maximum operative train speed. Particularly, the initiation of flight of ballast due to the pass of a high speed train has been studied by Kwon and Park (2006) by performing field and wind tunnel experiments.

A Schwarz lemma for Kahler affine metrics and the canonical potential of a proper convex cone

This is an account of some aspects of the geometry of Kahler affine metrics based on considering them as smooth metric measure spaces and applying the comparison geometry of Bakry-Emery Ricci tensors. Such techniques yield a version for Kahler affine metrics of Yau s Schwarz lemma for volume forms. By a theorem of Cheng and Yau, there is a canonical Kahler affine Einstein metric on a proper convex domain, and the Schwarz lemma gives a direct proof of its uniqueness up to homothety. The potential for this metric is a function canonically associated to the cone, characterized by the property that its level sets are hyperbolic affine spheres foliating the cone. It is shown that for an n -dimensional cone, a rescaling of the canonical potential is an n -normal barrier function in the sense of interior point methods for conic programming. It is explained also how to construct from the canonical potential Monge-Ampère metrics of both Riemannian and Lorentzian signatures, and a mean curvature zero conical Lagrangian submanifold of the flat para-Kahler space.

Gust wind tunnel study on ballast pick-up by high-speed trains

This paper describes the experimental setup, procedure, and results obtained, concerning the dynamics of a body lying on a floor, attached to a hinge, and exposed to an unsteady flow, which is a model of the initiation of rotational motion of ballast stones due to the wind generated by the passing of a high-speed train. The idea is to obtain experimental data to support the theoretical model developed in Sanz-Andres and Navarro-Medina (J Wind Eng Ind Aerodyn 98, 772–783, (2010), aimed at analyzing the initial phase of the ballast train-induced-wind erosion (BATIWE) phenomenon. The experimental setup is based on an open circuit, closed test section, low-speed wind tunnel, with a new sinusoidal gust generator mechanism concept, designed and built at the IDR/UPM. The tunnel’s main characteristic is the ability to generate a flow with a uniform velocity profile and sinusoidal time fluctuation of the speed. Experimental results and theoretical model predictions are in good agreement.

Dynamic Movements of Organelles Containing Niemann-Pick C1 Protein: NPC1 Involvement in Late Endocytic EventsV⃞

People homozygous for mutations in the Niemann-Pick type C1 (NPC1) gene have physiological defects, including excess accumulation of intracellular cholesterol and other lipids, that lead to drastic neural and liver degeneration. The NPC1 multipass transmembrane protein is resident in late endosomes and lysosomes, but its functions are unknown. We find that organelles containing functional NPC1-fluorescent protein fusions undergo dramatic movements, some in association with extending strands of endoplasmic reticulum. In NPC1 mutant cells the NPC1-bearing organelles that normally move at high speed between perinuclear regions and the periphery of the cell are largely absent. Pulse-chase experiments with dialkylindocarbocyanine low-density lipoprotein showed that NPC1 organelles function late in the endocytic pathway; NPC1 protein may aid the partitioning of endocytic and lysosomal compartments. The close connection between NPC1 and the drug U18666A, which causes NPC1-like organelle defects, was established by rescuing drug-treated cells with overproduced NPC1. U18666A inhibits outward movements of NPC1 organelles, trapping membranes and cholesterol in perinuclear organelles similar to those in NPC1 mutant cells, even when cells are grown in lipoprotein-depleted serum. We conclude that NPC1 protein promotes the creation and/or movement of particular late endosomes, which rapidly transport materials to and from the cell periphery.

Sphingosylphosphocholine, a signaling molecule which accumulates in Niemann-Pick disease type A, stimulates DNA-binding activity of the transcription activator protein AP-1.

Sphingosylphosphocholine (SPC) is the deacylated derivative of sphingomyelin known to accumulate in neuropathic Niemann-Pick disease type A. SPC is a potent mitogen that increases intracellular free Ca2+ and free arachidonate through pathways that are only partly protein kinase C-dependent. Here we show that SPC increased specific DNA-binding activity of transcription activator AP-1 in electrophoretic mobility-shift assays. Increased DNA-binding activity of AP-1 was detected after only 1-3 min, was maximal after 6 hr, and remained elevated at 12-24 hr. c-Fos was found to be a component of the AP-1 complex. Northern hybridization revealed an increase in c-fos transcripts after 30 min. Since the increase in AP-1 binding activity preceded the increase in c-fos mRNA, posttranslational modifications may be important in mediating the early SPC-induced increases in AP-1 DNA-binding activity. Western analysis detected increases in nuclear c-Jun and c-Fos proteins following SPC treatment. SPC also transactivated a reporter gene construct through the AP-1 recognition site, indicating that SPC can regulate the expression of target genes. Thus, SPC-induced cell proliferation may result from activation of AP-1, linking signal transduction by SPC to gene expression. Since the expression of many proteins with diverse functions is known to be regulated by AP-1, SPC-induced activation of AP-1 may contribute to the pathophysiology of Niemann-Pick disease.

Improved solutions to dynamic and stochastic maritime pick-up and delivery problems using local search.

Heuristics for stochastic and dynamic vehicle routing problems are often kept relatively simple, in part due to the high computational burden resulting from having to consider stochastic information in some form. In this work, three existing heuristics are extended by three different local search variations: a first improvement descent using stochastic information, a tabu search using stochastic information when updating the incumbent solution, and a tabu search using stochastic information when selecting moves based on a list of moves determined through a proxy evaluation. In particular, the three local search variations are designed to utilize stochastic information in the form of sampled scenarios. The results indicate that adding local search using stochastic information to the existing heuristics can further reduce operating costs for shipping companies by 0.5–2 %. While the existing heuristics could produce structurally different solutions even when using similar stochastic information in the search, the appended local search methods seem able to make the final solutions more similar in structure.
