Factors Controlling the Spatial Variability of Mercury Distribution in Spanish Topsoil
Soil and Sediment Contamination: An International Journal, 2008 This study characterized the sources and scales of mercury variability in agricultural soils of the river Ebro (9.5 million ha) using geostatistical methods and data from 624 samples. The Ebro basin (20% of Spanish land mass) is an important agricultural area that is industrialized.

PeerJ, 2020 Diatoms are generally regarded as inhabitants of water bodies. However, numerous taxa are able to survive and reproduce in a variety of non-aquatic ecosystems. Although terrestrial diatoms are discussed extensively in the literature, most of those studies covered floristic aspects and few information exists on their ecology.

Gravity compensation and optimal control of actuated multibody system dynamics
IET Control Theory & Applications, 2022 This work investigates the gravity compensation topic, from a control perspective. The gravity could be levelled by a compensating mechanical system or in the control law, such as proportional derivative (PD) plus gravity, sliding mode control, or ...

Memetic algorithms for Spatial Partitioning problems [PDF]
, 2022 Spatial optimization problems (SOPs) are characterized by spatial relationships governing the decision variables, objectives, and/or constraint functions. In this article, we focus on a specific type of SOP called spatial partitioning, which is a combinatorial problem due to the presence of discrete spatial units.

Spatial and temporal variability in cyanobacterial populations controlled by physical processes [PDF]
Journal of Plankton Research, 2004 The Fitzroy impoundment is a long slender water body (10 m deep) formed by the regulation of the Fitzroy River in tropical Australia. Large, monsoonally driven discharges in late summer flush the impoundment repeatedly leaving, after 2 months, a longitudinally uniform, well-mixed water column, rich in dissolved nutrients and with high turbidity.
