Nitrogen application and mowings improve chromium phytoextraction efficiency of Leersia hexandra Swartz

open access: yesEnvironmental Sciences Europe
Phytoextraction is a promising option for Cr-contaminated soil, but the long remediation period remains a primary hindrance to its large-scale application.

Adsorption of Arsenic by Magnetically Modified Biochar from Mulberry Tree Stems

open access: yesToxics
In this study, mulberry tree stems were used as raw material to prepare magnetic modified biochar, Fe-BC-500, using the co-precipitation method. The structure of Fe-BC-500 was systematically characterized and tested for arsenic (As) adsorption in batch ...

Embedded Model Control: design separation under uncertainty

open access: yes, 2014
The key signal of the Embedded Model Control (EMC) is the model error, measured minus model output, which is used by Internal Model Control and in a more efficient way by Active Disturbance Rejection Control (ADRC).

Invasion theory and biological control. [PDF]

open access: yes, 2002
Recent advances in the mathematical theory of invasion dynamics have much to offer to biological control. Here we synthesize several results concerning the spatiotemporal dynamics that occur when a biocontrol agent spreads into a population of an ...

Valorization of Red Mud, Steel Slag, and Desulfurization Slag as Industrial Solid-Waste-Derived Catalysts for Ciprofloxacin Degradation via H2O2 and Peroxymonosulfate Activation

open access: yesCrystals
This study used red mud (RM), steel slag (SS), and desulfurization slag (DS) as raw materials to construct three catalytic oxidation systems, namely RM-DCDA/H2O2, SS-DS/H2O2, and SS-DS/peroxymonosulfate (PMS), to promote the utilization of industrial ...

Controllability of Bilinear Systems: Lie Theory Approach and Control Sets on Projective Spaces

open access: yes
Bilinear systems can be developed from the point of view of time-varying linear differential equations or from the symmetry of Lie theory, in particular Lie algebras, Lie groups, and Lie semigroups. For bilinear control systems with bounded control range,

To Control or Be Controlled: Predicting Types of Offending in a Corporate Environment Using Control-Balance Theory [PDF]

open access: yes, 2019
Introduction: This study seeks to determine the extent to which Tittle’s control balance (CB) theory (CBT: 1995) accurately predicts different types of deviance within a corporate setting (in this case, a financial services corporation).

Microgrids as Flexible and Network-Connected Grid Assets in Active Distribution Systems

open access: yesJournal of Electrical and Computer Engineering, 2018
The functionalities of microgrids are detailed and thereby expanded in active distribution systems. A versatile and coordinated operation among multiple microgrids is proposed to facilitate the integration of renewable energy sources (RES) in modern ...

An examination of attentional control theory, perceptual anticipation and dual task paradigms [PDF]

open access: yes, 2018
Skilled perceptual anticipation, the capability of anticipating the actions of others and processing information under severe time- and task-constraints, is a critical component in many dynamic real-world activities and cognitive tasks, particularly in ...
