Abstract: Una faena de hormigonado controlada según la capacidad de recorrer un perímetro completo con concreto producido en obra es el origen de estos muros estratificados, que dan cuenta de las variaciones asociadas a la factura artesanal y los cambios climáticos durante la construcción. The capacity to cover the entire perimeter of the building with concrete produced in situ originated these stratified walls. Their surface variations result from a hand made process and weather changes during construction.
A la vera del camino

Abstract: la aceleración de nuestra cultura ha hecho que lo que separa pasado, presente y futuro sea de una consistencia cada vez más atenuada e ilegible. y los arquitectos, antes inequívocamente inclinados a la permanencia y a la durabilidad, hoy incorporan la palabra temporal (luego de novedad, joven, reciente) como valor convencional. ?cómo situarse en una época en que la avidez por lo nuevo se transforma, en palabras de javier marías, en "el desdén por lo que existe y la fascinación por lo inexistente"? la arquitectura, entre demoliciones, remodelaciones y persistencias, se resiste a un destino estático: toda ella aparece como registro de lo que ya ha pasado, pero ciertamente es el reflejo de lo que está siendo hoy.

Self-gravitating branes of codimension 4 in Lovelock gravity
Robin Zegers
Physics , 2008, DOI: 10.1088/1126-6708/2008/03/066
Abstract: We construct a familly of exact solutions of Lovelock equations describing codimension four branes with discrete symmetry in the transverse space. Unlike what is known from pure Einstein gravity, where such brane solutions of higher codimension are singular, the solutions we find, for the complete Lovelock theory, only present removable singularities. The latter account for a localised tension-like energy-momentum tensor on the brane, in analogy with the case of a codimension two self-gravitating cosmic string in pure Einstein gravity. However, the solutions we discuss present two main distinctive features : the tension of the brane receives corrections from the induced curvature of the brane's worldsheet and, in a given Lovelock theory, the spectrum of possible values of the tension is discrete. These solutions provide a new framework for the study of higher codimension braneworlds.
Birkhoff's theorem in Lovelock gravity
Robin Zegers
Mathematics , 2005, DOI: 10.1063/1.1960798
Abstract: We show that the generic solutions of the Lovelock equations with spherical, planar or hyperbolic symmetry are locally isometric to the corresponding static Lovelock black hole. As a consequence, these solutions are locally static: they admit an additional Killing vector that can either be space-like or time-like, depending on the position. This result also holds in the presence of an abelian gauge field, in which case the solutions are locally isometric to a charged static black hole.
q,t-characters and the structure of the $\ell$-weight spaces of standard modules over simply laced quantum affine algebras
R. Zegers
Mathematics , 2014,
Abstract: We establish, for all simply laced types, a q,t-character formula, first conjectured by Nakajima. It relates, on one hand, the structure of the $\ell$-weight spaces of standard modules regarded as modules over the Heisenberg subalgebra of some quantum affine algebra and, on the other hand, the t-dependence of their q,t-characters, as originally defined in terms of the Poincar\'e polynomials of certain Lagrangian subvarieties in quiver varieties of the corresponding simply laced type. Our proof is essentially geometric and generalizes to arbitrary simply laced types earlier representation theoretical results for standard $\mathrm{U}_q (\widehat{\mathfrak{sl}}_2)$-modules.
LA MUERTE Y EL SUICIDIO EN LA POESíA DE R. M. RILKE
D?rr Zegers,Otto;
Acta bioethica , 2000, DOI: 10.4067/S1726-569X2000000100009
Abstract: suicide can be understood only as a result of a previous reflection about death. with reference to some texts by hegel, goethe and heidegger, the author proposes a conception of death, not only as a part of life but also as 'that' that gives meaning to it. a similar idea, though expressed in a very original way, is the one sustained by the poet rainer maria rilke in a letter to his editor in polish, w. hulewicz, of november 13, 1925. the author tries to study more deeply the poet's thought concerning death, through the analysis of the eighth, ninth and tenth duino elegies (1922), poems where rilke develops his concept of the "personal death", announced in his novel, the notes of malte laurids brigge (1910). to him, life itself consists of "learning to die", of preparing in advance "the masterpiece of a noble death..., of a consummate, happy and enthusiastic death, as only saints were able to conceive it". then, the question is what could happen to induce someone not to wait for his /her own death and destroy with a suicidal act the harmony of life and death?. the poet gives the answer in the requiem for wolf von kalckreuth (1908). the one committing suicide does not recognize in earth the possibility of joy, as something that, sometimes, is hidden amid pain. secondly, the suicide hurries to give life and death a definitive interpretation, without allowing life -in its own way- to unveil the meaning of the existence. finally, rilke's suicidal young, who happened to be a poet, did not let his work mature, perhaps he did not understand what was the essence of poetry: that the poet transforms himself in the words that eternalize things
Dilemas de la reproducción asistida
Zegers-Hochschild, Fernando;
Cadernos de Saúde Pública , 1998, DOI: 10.1590/S0102-311X1998000500002
Abstract: modern reproductive technologies, particularly in vitro fertilization (ivf) and gamete intrafallopian transfer (gift), have made possible the establishment of new families through the birth of hundreds of thousands of children worldwide. meanwhile, these technologies have compelled men to face the possibility of intervening at the very origins of their own biological existence, hence creating doubts and questions beyond the domain of medical science. society is now asking itself whether all that is scientifically and technically possible is necessarily beneficial to mankind. the answer to this question is not to be found in biological science alone, but instead requires multidisciplinary reflection including all forms of knowledge: philosophical, bioethical, and religious, all contributing to the unavoidable adventure that we are endowed with in the search for a better life.
éTICA Y PSIQUIATRíA: ASPECTOS EN LA PRAXIS COTIDIANA
D?RR ZEGERS,OTTO;
Revista Colombiana de Psiquiatría , 2002,
Abstract: paper poses diverse ethical aspects, relevant to medical practice in general, and to psychiatry in particular, with special emphasis in psychotherapy. concern with ethical momentum of the medical act dates back to ancient greek culture, when hippocratic revolution transformed magical medical practice into science. a science inseparable from art, when alluding to the subjectivity, vital experience and environment of the human being. through a journey across hellenic word, most platonic thought, christian ideas and diverse aspects at the present time, ?problems? related to psychiatric diagnosis, pharmacotherapy and psychotherapy are studied. finally, a strategy is proposed, according to the selected theoretical framework, and the patient′s own pathology.
Eros y Tánatos
D?rr Zegers, Otto;
Salud mental , 2009,
Abstract: eros and thanatos, respectively, love and death, are universal subjects in which human beings have been interested since the beginning of history and also probably, their access to language. the greatest philosophers, poets and novelists have focused on these subjects in their reflections and/or their own development. fully conscious of the lack of moderation of the task proposed, the author intends to make a modest contribution to these two concepts and what they represent, inspired by two sources: classical myths, on the one hand, and the work of some poets and thinkers, mainly plato, goethe and rilke, on the other hand. eros or love in most ancient greek myths, eros is considered as one of the great constitutive and constituent principles of the universe, as the irresistible force allowing the continuity of life in human beings and animals, in the earth and in the waters. but eros is also a god and his legend shows us some essential features of love: 1. love is involuntary, it occurs, it happens, like a disease. eros had the mission of punishing psyche for her beauty, thus avenging the jealous aphrodite, his mother. and however, it was enough for him to look upon her only once to become impassioned by her. but this passion goes together with its opposite, liberty, because love always carries implicit a choice. 2. love, unlike friendship, which is slowly shaped, appears in a sudden way, represented by the arrows used by eros (cupid) to inflame lovers' hearts. safo described this phenomenon of suddenness superbly. 3. the myth also teaches us the exclusive character of love. this feature separates love from erotism. some verses by the poet gonzalo rojas are quoted to illustrate what he calls <> to exclusiveness. 4. another characteristic of love inferred from the myth is transgression, which almost always accompanies it. eros did not have the right to fall in love with a mortal woman and, however, he is not able to withdraw from the feeling invading hi
