Water Resources Research, Volume 60, Issue 5, May 2024.Abstract Agricultural run‐off exposes recipient water bodies to nitrate (NO3−) pollution. Biological denitrification is a suitable method for removing NO3− in water resources that can be induced by the use of industrial organic liquid waste as an electron donor source.

The 2021 La Palma eruption: social dilemmas resulting from life close to an active volcano
Geology Today, Volume 40, Issue 3, Page 96-111, May/June 2024.Damage and destruction caused by the 2021 eruption of the Tajogaite volcano on La Palma was unprecedented relative to other historical eruptions of the last century (1909, 1949, 1971, 2011) in the Canary Islands. The devastation caused by the eruption was not a result of eruption magnitude, which was only marginally larger than other historical events,

Tectonics, Volume 43, Issue 4, April 2024.Abstract Metamorphic basements are usually considered rigid and isotropic at a large scale. However, basements contain inherited weaknesses that may potentially accommodate superimposed contraction (e.g., fault reactivation), and that favor fold nucleation (e.g., penetrative foliations).

Ornamental granite durability: evaluation of damage caused by salt crystallization
Materiales de Construccion, 2008 The salt crystallization test is used to evaluate damage caused by soluble salts that penetrate stone and subsequently crystallize in its voids (pores or cracks). The present article discusses the findings for four ornamental granites (gris alba, grissal,
