Existence of non-negative solutions for semilinear elliptic systems via variational methods
Nonlinear Analysis, 2012 In this paper we consider a semilinear elliptic system with nonlinearities, indefinite weight functions and critical growth terms in bounded domains. The existence result of nontrivial nonnegative solutions is obtained by variational methods.

Spanish stock returns, growth, and inflation, 1900–2020
The Economic History Review, EarlyView.Abstract This paper studies equity returns in the Madrid Stock Exchange and their connections with the macroeconomy from the emergence of a stock market around 1900 to its ‘big bang’ at the turn of the twenty‐first century. Using high‐quality data from primary sources and the methodology of the modern IBEX35 (published since 1987), we constructed an ...

Equine Veterinary Journal, EarlyView.Abstract Background Arsenic poisoning in horses is rarely reported in the literature. However, arsenic compounds can be present in rodenticides, pesticides, and herbicides, representing a potential source of accidental exposure for horses. Objective To describe the epidemiological, clinical, and laboratory findings from a herd of 31 horses exposed to ...

On the second eigenvalue of a Hardy-Sobolev operator
Electronic Journal of Differential Equations, 2004 In this note, we study the variational characterization and some properties of the second smallest eigenvalue of the Hardy-Sobolev operator $L_{mu}:=-Delta_{p}-frac{mu}{|x|^p}$ with respect to an indefinite weight $V(x)$.

A singular perturbation result for a class of periodic-parabolic BVPs
Open MathematicsIn this article, we obtain a very sharp version of some singular perturbation results going back to Dancer and Hess [Behaviour of a semilinear periodic-parabolic problem when a parameter is small, Lecture Notes in Mathematics, Vol. 1450, Springer-Verlag,

The maternal role of community‐dwelling older women: A qualitative study
Family Relations, EarlyView.ABSTRACT Objective To explore the maternal role through the subjective experiences of community‐dwelling older mothers. Background Participation in meaningful life roles is essential for older adults' health. Motherhood, a meaningful life role of many women, includes various activities, but research has not focused on this role at older age. This study

Electronic Journal of Differential Equations, 2016 In this article, we give a priori bounds on the possible non-real eigenvalue of regular fourth-order boundary value problem with indefinite weight function and obtain a sufficient conditions for such problem to admit non-real eigenvalue.
