Free-phase gasoline remedial schemes are based on the gasoline’s thickness layer measured on monitoring wells. The relationship of the thickness within the well and in the aquifer depends on the elevation of the water table.

Pre-images of quadratic dynamical systems [PDF]
For a quadratic endomorphism of the affine line defined over the rationals we consider the problem of bounding the number of rational points that eventually land at a given constant after iteration, called pre-images of the constant.

Exact $G_2$-structures on unimodular Lie algebras [PDF]
We consider seven-dimensional unimodular Lie algebras $\mathfrak{g}$ admitting exact $G_2$-structures, focusing our attention on those with vanishing third Betti number $b_3(\mathfrak{g})$. We discuss some examples, both in the case when $b_2(\mathfrak{g}

The Cyclicality of Immigrant Wages and Labour Market Flows: Evidence from Spain
This article studies the responses of real wages and labour market flows of immigrants in Spain for the period between 1999 and 2019. By using Labour Force Survey microdata, I examine the cyclicality of job-finding and job-separation rates for immigrants

Non-Kaehler Heterotic String Solutions with non-zero fluxes and non-constant dilaton [PDF]
Conformally compact and complete smooth solutions to the Strominger system with non vanishing flux, non-trivial instanton and non-constant dilaton using the first Pontrjagin form of the (-)-connection} on 6-dimensional non-Kaehler nilmanifold are ...

Ramanujan and coefficients of meromorphic modular forms [PDF]
The study of Fourier coefficients of meromorphic modular forms dates back to Ramanujan, who, together with Hardy, studied the reciprocal of the weight 6 Eisenstein series. Ramanujan conjectured a number of further identities for other meromorphic modular

Classification of Symmetry Lie Algebras of the Canonical Geodesic Equations of Five-Dimensional Solvable Lie Algebras [PDF]
In this investigation, we present symmetry algebras of the canonical geodesic equations of the indecomposable solvable Lie groups of dimension five, confined to algebras A_{5,7}^{abc} to A_{18}^a.
