[EN] We establish the existence and uniqueness of a positive and nondecreasing solution to a singular boundary value problem of a class of nonlinear fractional differential equation. Our analysis relies on a fixed point theorem in partially ordered sets.

[EN] Stommel has been the most important physicist oceanographer of the second half of the XX century. Builder, to a great extent, of the present Dynamical Oceanography. He contributed to the transformation of the Oceanography from a sort of appendix of the studies of the Atmosphere to a new specialty of Geophysics. After graduating in Astronomy in Yale in 1942 he started his research participating in the WWII effort, collaborating together with many other future oceanographers, in support of the USA Navy. Research that was carried out in the Woods Hole Oceanographic Institution (WHOI). Between 1959 and 1978 he was professor of oceanography in Harvard U. first, and later in the Massachusetts Institute of Technology, returning to WHOI where he stayed until his death. Stommel established important and fundamental theories on the ocean global circulation and studied many other oceanographic phenomena. This theoretical activity he combined with not a less important observational one. He received many awards and hhonors, including the Craadford prize, equivalent to the Nobel in Geosciences.

[ES]Hemos analizado la posible relación entre la presencia de contaminantes emergentes en agua regenerada para riego, agua del lixiviado del suelo y agua subterránea y la resistencia a antibióticos de las bacterias aisladas. Se tomaron muestras de agua. Cada muestra se dividió en dos partes. Una se centrifugó y se resembró en diferentes medios. Cincuenta mililitros de la segunda parte se añadieron a Caldo Brain Heart. En la siembra directa de agua de riego y solución del suelo se detectaron numerosas colonias. El crecimiento en la siembra directa de agua de galería fue escaso, y no hubo crecimiento cuando se sembró agua de pozo. Mediante enriquecimiento en Caldo BHI y resiembra posterior, se obtuvieron numerosas colonias
