Sexuar las diferencias

Este ensayo interpreta y elabora la metáfora de la danza, utilizada por Derrida en sus respuestas a los cuestionamientos acerca de los feminismos que le hace McDonald en "Coreografías", el famoso diálogo entre ambos. La imagen de la danza es el medio para construir la propuesta derridiana de la diferencia sexual

Interlaced spin grating for optical wave filtering

Interlaced Spin Grating is a scheme for the preparation of spectro-spatial periodic absorption gratings in a inhomogeneously broadened absorption profile. It relies on the optical pumping of atoms in a nearby long-lived ground state sublevel. The scheme takes advantage of the sublevel proximity to build large contrast gratings with unlimited bandwidth and preserved average optical depth. It is particularly suited to Tm-doped crystals in the context of classical and quantum signal processing. In this paper, we study the optical pumping dynamics at play in an Interlaced Spin Grating and describe the corresponding absorption profile shape in an optically thick atomic ensemble. We show that, in Tm:YAG, the diffraction efficiency of such a grating can reach 18.3% in the small angle, and 11.6% in the large angle configuration when the excitation is made of simple pulse pairs, considerably outperforming conventional gratings.Comment: 11 pages, 13 figures in Physical Review A, 201

Economic Evidence for Pharmacist-Led Medicines Use Review and Medicines Reconciliation

Pharmacist-led medicines use review (MUR) and medicines reconciliation (MedRec) aim to identify, resolve and prevent patient-related drug-related problems (DRP) and medication discrepancies in order to optimize medicines use and ensure the patient safety. As “diagnostic-resolution” interventions, the question of their economic impact and cost-effectiveness from healthcare systems perspective is crucial, and the level of their related evidence could support or challenge the dissemination and sustainability of these interventions in health systems. This chapter addresses two main questions: how is the economic impact and cost-effectiveness of these interventions modelling in the literature? And what is the economic evidence for these interventions? This content derives from the identification and selection of full economic evaluations of MUR and MedRec and systematic reviews or meta-analyses for which the main outcome was to assess their economic impact. Despite the demonstration of their effectiveness in identifying and resolving safety issues (patient-related DRP and edication discrepancies), studies have struggled to demonstrate their clinical and economic impact, probably due to the poor quality and heterogeneity of the studies, as well as the debatable accuracy of the outcomes. Future research and high-quality studies are needed to address these issues

Differential inductive sensing system for truly contactless measuring of liquids’ electromagnetic properties in tubing

Certain applications require a contactless measurement to eliminate the risk of sensorinduced sample contamination. Examples can be found in chemical process control, biotechnology or medical technology. For instance, in critically ill patients requiring renal replacement therapy, continuous in‐line monitoring of blood conductivity as a measure for sodium should be considered. A differential inductive sensing system based on a differential transformer using a specific flow chamber has already proven suitable for this application. However, since the blood in renal replacement therapy is carried in plastic tubing, a direct measurement through the tubing offers a contactless method. Therefore, in this work we present a differential transformer for measuring directly through electrically non‐conductive tubing by winding the tube around the ferrite core of the transformer. Here, the dependence of the winding type and the number of turns of the tubing on the sensitivity has been analyzed by using a mathematical model, simulations and experimental validation. A maximum sensitivity of 364.9 mV/mol/L is measured for radial winding around the core. A longitudinal winding turns out to be less effective with 92.8 mV/mol/L. However, the findings prove the ability to use the differential transformer as a truly contactless sensing system. © 2021 by the authors. Licensee MDPI, Basel, Switzerland

How geometry affects sensitivity of a differential transformer for contactless characterization of liquids

The electrical and dielectric properties of liquids can be used for sensing. Specific appli-cations, e.g., the continuous in-line monitoring of blood conductivity as a measure of the sodium concentration during dialysis treatment, require contactless measuring methods to avoid any contam-ination of the medium. The differential transformer is one promising approach for such applications, since its principle is based on a contactless, magnetically induced conductivity measurement. The objective of this work is to investigate the impact of the geometric parameters of the sample or medium under test on the sensitivity and the noise of the differential transformer to derive design rules for an optimized setup. By fundamental investigations, an equation for the field penetration depth of a differential transformer is derived. Furthermore, it is found that increasing height and radius of the medium is accompanied by an enhancement in sensitivity and precision. © 2021 by the authors. Licensee MDPI, Basel, Switzerland
