Marco Antonio de la Parra: Matatangos y la resemantización de su causa ausente

This article explores how ideas of patriarchy have shaped the nature and effect of rape law. It argues that rape law reinforces patriarchy, and because of the inherent inconsistencies between the male roles of aggressor and protector, it has remained ineffective. Taking Kenya as its springboard, it analyses how ideas of sexual relations within and outside marriage are transplanted through colonialism; and how they morph and merge with analogous indigenous conceptions to entrench and formalise the continued subjugation of the female body. It explores the unintended consequences of the internationalisation of English Monogamy; and rape law reform and its continuity/discontinuity with the Civilising Mission

Confinement Effects in Antiferromagnets

Phase equilibrium in confined Ising antiferromagnets was studied as a function of the coupling (v) and a magnetic field (h) at the surfaces, in the presence of an external field H. The ground state properties were calculated exactly for symmetric boundary conditions and nearest-neighbor interactions, and a full zero-temperature phase diagram in the plane v-h was obtained for films with symmetry-preserving surface orientations. The ground-state analysis was extended to the H-T plane using a cluster-variation free energy. The study of the finite-T properties (as a function of v and h) reveals the close interdependence between the surface and finite-size effects and, together with the ground-state phase diagram, provides an integral picture of the confinement in anisotropic antiferromagnets with surfaces that preserve the symmetry of the order parameter.Comment: 10 pages, 8 figures, Accepted in Phys.

Bauxitas kársticas jurásicas en la zona subbética (Zarzadilla de Totana, prov. de Murcia, sureste de España): Interpretación paleogeográfica

Los yacimientos de bauxitas de Zarzadilla de Totana (Murcia) selocalizan en materiales jurásicos del Subbético interno. Las bauxitas se emplazan rellenando cavidades kársticas en el seno de calizas del Lias infradomerense indicando claramente una etapa de emersión de un umbral pelágico que pudo durar parte del Lias superior y del Dogger

CFD study of the impact of the deviation on the mass flow inlet on winding hot-spot temperature of a power transformer using mineral and ester oils

This work presents a study where a deviation on the mass flow rate in adjacent sectors of the winding is considered. A CFD model was developed for this study, where heat transfer between sectors is enabled due to the lack of thermal symmetry, and the goal of this study is to determine whether this effect can be neglected or not. To carry out this study, a Low Voltage Winding of a 100 MVA power transformer was selected. This transformer has been manufactured and tested by BEST Transformers, and the results obtained from the heat run test were used to validate the CFD model. The study also considered an alternative dielectric liquid, natural ester, in order to estimate if the different thermal and hydraulic conditions can affect to the relevance of the studied effect. The CFD simulations have been carried out with ANSYS Fluent. The results showed a deviation of 3-4% of the heat dissipated due to the non-symmetric conditions with a 10% of mass flow deviation, which is the heat transfer between the adjacent sectors. This effect is identical when considering mineral oil or natural ester. The results shows there is a small impact of the winding temperatures due to this effect, and that it can be considered negligible.Part of the work was performed during secondments between BEST Transformers and the University of Cantabria executed in the framework of the BIOTRAFO project “Raising knowledge and developing technology for the design and deployment of high-performance power transformers immersed in biodegradable fluids”, H2020-MSCA-RISE2018- 823969, 2019-21.
