Historia de los balnearios de la provincia de Málaga

how a very different sense of time governed the way that the relations between the local West Indies naval bureaucracy and the central one in London were structured, with an order or explanation taking weeks or months to arrive, whilst nine months might elapse between the request for food or medicines and their arrival. Such time-lags encouraged a degree of local independence but all the major ...

Conservación de propiedades del anillo de polinomios y del anillo de series en la clase de los anillos de conductor finito

In this paper is considered the preservation of properties of the ring of coefficients R to the rings R[x] and R [[x]], where R[x] denotes the polynomials ring and R [[x]] is the power series ring. This study is carry out in the context of finite conductor rings; in particular, properties like GCD, G − GCD, coherence, quasi coherence and finite conductor are analized.

Cálculo de la Incertidumbre en la Medición Visual de los Parámetros de un Péndulo de Foucault

We present a method for determining the uncertainty in the measurement of parameters that describe the dynamics of a Foucault's pendulum. In the document, we review how these parameters can be obtained. Then, we propose a method for evaluating the uncertainty in their determination. We illustrate the method with experimentation made on a 28m height pendulum located at 20° 35' north latitude.
