Evaluación del comportamiento energético de las estaciones depuradoras de aguas residuales: Una aproximación económica

2019

Las Estaciones Depuradoras de Aguas Residuales (EDARs) son una pieza básica del conjunto de infraestructuras urbanas, ya que son indispensables para garantizar la salud pública y del medio ambiente. Actualmente, en España existen aproximadamente 3.000 EDARs que tratan 4.700 hm3 de aguas residuales, de los cuales la mayor parte, un 55,8% y un 33,5% son vertidos a cauces fluviales y al mar, respectivamente, mientras que un 10,4% es reutilizado en la agricultura y el riego de jardines, y el 0,3% restante es infiltrado al suelo para la regeneración de acuíferos y otros fines. Según el destino del agua residual, la normativa en materia de aguas residuales urbanas y reutilización requiere el cump…

Costruzioni eikota. Verità ed efficacia nella cura psicoanalitica.

2011

This article proposes to add the Greek notion of eikos to the debate on the epistemological mandate of psychoanalisis. This term is traditionally translated as likely or probable. The proposed thesis is that such a notion, if adequately understood, can offer an interesting starting point for the understanding of the Freudian concepts of “construction” and “historical truth”.

Generalized curved beam on elastic foundation solved by Transfer Matrix Method

2011

A solution of space curved bars with generalized Winkler soil found by means of Transfer Matrix Method is presented. Distributed, concentrated loads and imposed strains are applied to the beam as well as rigid or elastic boundaries are considered at the ends. The proposed approach gives the analytical and numerical exact solution for circular beams and rings, loaded in the plane or perpendicular to it. A well-approximated solution can be found for general space curved bars with complex geometry. Elastic foundation is characterized by six parameters of stiffness in different directions: three for rectilinear springs and three for rotational springs. The beam has axial, shear, bending and tor…

Active macro-zone approach for incremental elastoplastic-contact analysis

2013

The symmetric boundary element method, based on the Galerkin hypotheses, has found an application in the nonlinear analysis of plasticity and in contact-detachment problems, but both dealt with separately. In this paper, we want to treat these complex phenomena together as a linear complementarity problem. A mixed variable multidomain approach is utilized in which the substructures are distinguished into macroelements, where elastic behavior is assumed, and bem-elements, where it is possible that plastic strains may occur. Elasticity equations are written for all the substructures, and regularity conditions in weighted (weak) form on the boundary sides and in the nodes (strong) between cont…

Multidomain SBEM analysis of two dimensional elastoplastic-contact problems

2012

The Symmetric Boundary Element Method based on the Galerkin hypotheses has found application in the nonlinear analysis of plasticity and contact-detachment problems, but dealt with separately. In this paper we wants to treat these complex phenomena together. This method works in structures by introducing a subdivision into sub-structures, distinguished into macroelements, where elastic behaviour is assumed, and bem-elements, where it is possible for plastic strains to occur. In all the sub-structures, elasticity equations are written and regularity conditions in weighted (weak) form and/or in nodal (strong) form between boundaries have to be introduced, to attain the solving equation system.

Aspiration development among rural youth : case study Liceo Rural Sámara

2017

The aim of this thesis is to provide a preliminary analysis of the aspirations of rural youth in Sámara, Costa Rica and the factors influencing them. This study will supplement the existing literature on aspirations, while providing a new approach to this field. By assessing which factors are most influential to youth’s development of aspirations this study hopes to provide information which can help to improve infrastructure for the development of aspirations in the future. The ultimate goal is to guide future structural changes to promote the development and realization of youth’s aspirations. The study implements an actor-centered approach by utilizing questionnaire data gathered in the …

Zeitlicher Ablauf der ACTH-induzierten Stimulierung der Corticosteroidbiosynthese

1969

The time course of ACTH action was studied during incubation of quartered rat adrenals by estimation of corticosterone production and secretion rates. The results suggest a two step action of ACTH during the acute stimulation of corticosteroid biosynthesis: A modest initial stimulation was observed within the first 30 min of exposure to ACTH which was overlapped by a marked secondary stimulation between 30 and 60 min.
