Dam Reservoir Sediments as Fertilizers and Artificial Soils : Case Studies from Portugal and Brazil

The set of families K that we shall consider includes the family of real or imaginary quadratic fields, that of real biquadratic fields, the full cyclotomic fields, their maximal

In fact in order to show that Condorcet rankings are medians we are going to use a more general notion of median namely the notion of metric median in a metric space.. I begin by

Polynomials (2.1) satisfy the following very useful identity originally formulated for so called contin- uous q − Hermite polynomials h n (can be found in e.g.. First assertions

We show that a discrete fixed point theorem of Eilenberg is equivalent to the restriction of the contraction principle to the class of non-Archimedean bounded metric spaces.. We

The finite element method is used to simulate the variation of cavity pressure, cavity volume, mass flow rate, and the actuator velocity.. The finite element analysis is extended

In addition, under the above assumptions, we show, as in the uniform norm, that a function in L 1 (K, ν) has a strongly unique best approximant if and only if the best

We initiate the investigation of a stochastic system of evolution partial differential equations modelling the turbulent flows of a second grade fluid filling a bounded domain of R

Also, extended F-expansion method showed that soliton solutions and triangular periodic solutions can be established as the limits of Jacobi doubly periodic wave solutions.. When m →
