Cellular covers of local groups

We prove that, in the category of groups, the composition of a cellularization and a localization functor need not be idempotent. This provides a negative answer to a question of Emmanuel Dror Farjoun.Ministerio de Educación y CienciaJunta de Andalucí

Quantum RLCRLC circuits: charge discreteness and resonance

In a recent article, we have advanced a semiclassical theory of quantum circuits with discrete charge and electrical resistance. In this work, we present a few elementary applications of this theory. For the zero resistance, inductive circuit, we obtain the Stark ladder energies in yet another way; and generalize earlier results by Chandia et. al, for the circuit driven by a combination d.c. plus a.c. electromotive force (emf). As a second application, we investigate the effect of electrical resistance, together with charge discreteness, in the current amplitude, and resonance conditions of a general $RLC$ quantum circuit, including nonlinear effects up to third order on the external sinusoidal emf

Reseña de "LA PROFESIÓN UNIVERSITARIA EN EL CONTEXTO DE LA MODERNIZACIÓN" de Teresa Pacheco Méndez y Ángel Díaz Barriga

La lectura de este libro es una lectura obligada para los docentes, explora uno de los territorios en los que el conocimiento y sus tradicionales mecanismos institucionales de preservación (la profesión y la formación de profesionales) encaran la nueva dinámica del cambio, sobrellevando sus efectos. El principal interés de los autores es salir al encuentro de los puntos de contradicción a los que se enfrentan actualmente nuestras instituciones universitarias, que asumen la elevada responsabilidad de generar conocimiento y de formar sujetos sociales, con la perspectiva de ganar terreno a la fragmentación y a la segmentación de la vida institucional, producto de la modernización

An esp manual course for waiting staff: needs analysis and development

"Nowadays, relationships with English speaking countries force to any employee to develop social, cultural and even technological skills that is why waiters have to develop an intermediate level of English language. In this context, English for a Specific Purpose (ESP) becomes a very important area because that is exactly what the study will focus on.

Simple approach to the mesoscopic open electron resonator: Quantum current oscillations

The open electron resonator, described by Duncan et.al, is a mesoscopic device that has attracted considerable attention due to its remarkable behaviour (conductance oscillations), which has been explained by detailed theories based on the behaviour of electrons at the top of the Fermi sea. In this work, we study the resonator using the simple quantum quantum electrical circuit approach, developed recently by Li and Chen. With this approach, and considering a very simple capacitor-like model of the system, we are able to theoretically reproduce the observed conductance oscillations. A very remarkable feature of the simple theory developed here is the fact that the predictions depend mostly on very general facts, namely, the discrete nature of electric charge and quantum mechanics; other detailed features of the systems described enter as parameters of the system, such as capacities and inductances

A price model to assess the inflationary effects of the European Regional Policy

Social Accounting Matrices (SAM) are databases that complete the information provided by the input-output tables. They study the intersectorial relationships of an economy, the behaviour of consumers, the government or the foreign sector, while being able to close the income flow of rent. In this work, we deal with the European Regional Development Fund (ERDF) in Andalusia, a Spanish region classified as Objective 1 by the European Regional policy. We apply the Leontief model on the SAMs for 1990, 1995 and 1999 to get the gross output fall when we remove these regional funds. Furthermore, we develop a price model to assess the impact of this financial support on aggregate and sectorial prices.Social Accounting Matrix, Regional Accounting, Structural Analysis.

On the idempotency of some composite functors

We present examples of localization functors whose composition with certain cellularization functors is not idempotent, and vice versa.Ministerio de Educación y Cienci
