Salt‐induced nutritional and metabolic shifts in halophytes: implications for food security

Journal of the Science of Food and Agriculture, EarlyView.
Abstract Plant species vary in their response to salinity: some crops show a degree of salt tolerance, while halophytes – whether wild or cultivated – are characterized by a high capacity to thrive under saline conditions. Halophytes are considered a source of valuable secondary metabolites with potential economic value, yet they might also produce ...

A unified quantum theory I: gravity interacting with a Yang-Mills field

, 2013
Using the results and techniques of a previous paper where we proved the quantization of gravity we extend the former result by adding a Yang-Mills functional and a Higgs term to the Einstein-Hilbert action.Comment: v4: minor corrections in some formulas,

Transcranial Direct Corrent stimulation (tDCS) of the anterior prefrontal cortex (aPFC) modulates reinforcement learning and decision-making under uncertainty: A doubleblind crossover study [PDF]

, 2017
Reinforcement learning refers to the ability to acquire information from the outcomes of prior choices (i.e. positive and negative) in order to make predictions on the effect of future decision and adapt the behaviour basing on past experiences.

Solving for Blameless and Optimal Control Under Prioritized Safety Constraints

Optimal Control Applications and Methods, EarlyView.
Summary of the proposed method for solving for blameless and optimal control sequences. ABSTRACT In many safety‐critical optimal control problems, users may request multiple safety constraints that are jointly infeasible due to external factors such as subsystem failures, unexpected disturbances, or fuel limitations.

Process simulation, optimization, and cost analysis of a proposed sulfur recovery unit by applying modified Claus technology

Journal of Engineering and Applied Science
Removing sour gas from any suitable gas sweetening technology in a cost-effective and environmentally responsible manner is a major challenge. This paper discusses how to safely and economically dispose of small amounts of acid gases resulting from the ...

Reduced and Detailed Kinetic Models Comparison for Thermal Furnace of Sulfur Recovery Units

Chemical Engineering Transactions, 2019
Acid gas obtained from oil refineries contains large amounts of hydrogen sulfide, which are not allowed as the off-gas or burned to the atmosphere. The waste gas collected during the processes in the refineries contains a high amount of sulfur-bearing ...

Caloric restriction‐mediated reproductive lifespan extension across multiple strains of the clonal aquatic plant Lemna turionifera

Oikos, EarlyView.
Lifespan extension due to caloric restriction (CR) is a well‐established aspect of animal senescence that has been observed in many taxa. Contrastingly, there is much less evidence in plants, even though it is straightforward to manipulate CR by restricting photosynthesis through reduction in light intensity.

Emission Minimization of a Two-Stage Sour Water Stripping Unit Using Surrogate Models for Improving Heat Duty Control

Journal of Sustainable Development of Energy, Water and Environment Systems, 2019
Sour water are aqueous waste streams from oil refining operations, heavily contaminated with hydrogen sulfide and ammonia, which need to be stripped before reuse or disposal, avoiding damages to process and environment.
