On a Paun’s Conjecture in Membrane Systems
(Springer, 2007)
We study a P˘aun’s conjecture concerning the unsolvability of NP–complete problems by polarizationless P systems with active membranes in the usual framework, without cooperation, without priorities, without changing ...

Potential Release and Bioaccessibility of Metal/loids from Mine Wastes Deposited in Historical Abandoned Sulfide Mines
(Elsevier, 2023)
This study deals with the potential release of metal/loids from sulfide mine wastes upon weathering and the health risks associated with their accidental ingestion. To address this, a complete chemical and mineralogical ...

Spatial modes in one-dimensional models for capillary jets
(American Physical Society, 2016)
One-dimensional (1D) models are widely employed to simplify the analysis of axisymmetric capillary jets. These models postulate that, for slender deformations of the free surface, the radial profile of the axial velocity can ...

Robust Hybrid Control for Demand Side Management in Islanded Microgrids
(IEEE, 2021-11)
This paper focuses on designing a robust control law to manage the demand response of islanded microgrids composed of shifting and adjusting loads. On one side, Hybrid Dynamical System theory is suited here, because the ...

Reasoning on the usage control security policies over data artifact business process models
(ComSIS Consortium, 2022)
The inclusion of security aspects in organizations is a crucial aspect to ensure compliance with both internal and external regulations. Business process models are a well-known mechanism to describe and automate the ...

Extending BPMN 2.0 for Modelling the Combination of Activities That Involve Data Constraints
(Springer, 2012)
The combination of activities to achieve optimal goals sometimes has a complex solution. Business Process Model and Notation (BPMN) 2.0 facilitates the modelling of business processes by providing new artifacts, such ...

Molybdenum cofactor (chlorate-resistant) mutants of Klebsiella pneumoniae M5al can use hypoxanthine as the sole nitrogen source.
(American Society for Microbiology, 1992)
Selection for chlorate resistance yields mol (formerly chl) mutants with defects in molybdenum cofactor synthesis. Complementation and genetic mapping analyses indicated that the Klebsiella pneumoniae mol genes are ...

Assessing the transcriptional regulation of L-cysteine desulfhydrase 1 in Arabidopsis thaliana
(Frontiers Media, 2014)
Hydrogen sulfide is an important signaling molecule that functions as a physiological gasotransmitter of comparable importance to NO and CO in mammalian systems. In plants, numerous studies have shown that sulfide increases ...

Influence of the AOT Counterion Chemical Structure on the Generation of Organized Systems
(American Chemical Society, 2020)
The impact of the imidazolium counterion structure on the organized systems formed by the surfactant 1,4-bis-2-ethylhexylsulfosuccinate, AOT, both in aqueous solutions and in nonpolar solvents is investigated. With this ...
