La coacción del estado

In this paper, the author offers a morphological study ot coercion as a means ot social control organized within political society. We are dealing here with a highly descriptive study, a tact which does not prevent the author from incidentally making scientitic appraisals or trom delíberately offering the bases tor appreciations ot an ethical and social nature. After a series ot introductory considerations destined to put torth the presence and objectives ot coercion and ot violence within the ample panorama ot social realíty -and particularly within the framework ot political experiences- the author proposes a precise concept ot coercion which serves as a gUide tor a more complete and more satistactory typological analysis ot the same. The first step in this analysis consists ot the differentiation between the two main types ot material coercion -physical and moral- and that type ot coercion which the author calls virtuai, which tinds its most commonly known and treated manitestation in mandates and imperative acts. It is important to point out the observations dedicated to the concepts ot admonition and ot degradation as the principal forms ot moral coercion, as well as those which are brought to bear upon the idea ot political Constitution in its relations with the phenomena of material and virtual coercion. In the concepts of political «retention» and «subjection», we find a plausible base of discussion for making up a realístic image of the Constitution of the State, as it is considered in one of its facets. The author then dedicates a large part ot his study to examining the diverse modalíties of coercion, keeping in mind the different functions which it can accomplish. He then explains, along with the thoroughly studied torms of reparatory and dissuasive coercion, the ideas of basic polítical coercion -to be found in practice in deportation measures, for example-, ot eliminatory coercion -which touches, very characteristically, acts pertaining to the políce- and of testimonial coercion. The study of this last type leads to the establishment ot various interesting conclusions with regard to judicial proceedings of a polítical nature, and the exercise of the prerogative ot penal grace by means of amnesty or indult. Finally, the explanation of the contrast between ponderable coercion and expeditious coercion contributes to the desirable finality ot correctly determining the límits ot Law within the framework ot coercion as a means of social control within the State

Using Google Glass in human-robot swarm interaction

We study how a human operator can guide a swarm of robots when transporting a large object through an environment with obstacles. The operator controls a leader robot that influences the other robots of the swarm. Follower robots push the object only if they have no line of sight of the leader. The leader represents a way point that the object should reach. By changing its position over time, the operator effectively guides the transporting robots towards the final destination. The operator uses the Google Glass device to interact with the swarm. Communication can be achieved via either touch or voice commands and the support of a graphical user interface. Experimental results with 20 physical e-puck robots show that the human–robot interaction allows the swarm to transport the object through a complex environment

Near-barrier Fusion Induced by Stable Weakly Bound and Exotic Halo Light Nuclei

The effect of breakup is investigated for the medium weight $^{6}$Li+$^{59}$Co system in the vicinity of the Coulomb barrier. The strong coupling of breakup/transfer channels to fusion is discussed within a comparison of predictions of the Continuum Discretized Coupled-Channels model which is also applied to $^{6}$He+$^{59}$Co a reaction induced by the borromean halo nucleus $^{6}$He.Comment: 6 pages, 3 figures.

Object oriented modelling and simulation of hydropower plants with run-of-river scheme: A new simulation tool

This paper presents the design of a component library for modelling hydropower plants, and describes the development of a new simulation tool for small hydropower plants with a run-of-river scheme. After reviewing the desirable features of simulation, an approach based on an object oriented modelling language, like EcosimPro, is presented. A general model of hydropower plant with run-of-river scheme is created with this component library. It provides the possibility of choosing a specific number of turbines and spillway gates. In this way, several hydropower stations of similar operating characteristics can be simulated using this same general model. It is expected to obtain interesting information in simulation like the reservoir level, water flows, turbine efficiencies, and so on. In addition, a graphical user interface has been designed in order to operate this general model more easily, to configure plant parameters and to simulate the plant behaviour under different conditions. Three real stations have been used as real examples for validating the model and testing the simulator: hydropower stations of Villafranca and El Carpio (Córdoba, Spain) and Marmolejo (Jaén, Spain)

Osteolisis tibial secundaria a un implante ligamentoso de Leeds-Keio: Presentación de un caso

Hasta hace algunos años, el ligamento artificial de Leeds-Keio, se usó en muchos casos para la reconstrucción de lesiones del ligamento cruzado anterior. Hoy día no se usa para este tipo de lesiones debido a los pobres resultados que se observaron a medio y largo plazo. No obstante, su uso está indicado en otras lesiones, como son la reconstrucción del aparato extensor de la rodilla, y en inestabilidades del hombro y de la columna vertebral. Presentamos un caso de osteolisis masiva del platillo tibial que requirió la retirada del implante seguida de autoinjerto óseo, complicación que no ha sido comunicada anteriormenteSome years ago the Leed-Keio prosthesis was widely used for anterior cruciate ligament repair. Due to the poor middle and long-term results, this technique has been abandoned. However, synthetic implants are used for other lesions such as knee extensor mechanism rupture and shoulder or lumbar spine instabilities. This paper presents a case of massive osteolysis of the tibial plateau requiring removal of the prosthesis and autologous bone graft, a complication not reported before
