Overlapping Schwarz waveform relaxation method for the solution of the convection-diffusion equation
( John Wiley & Sons, Ltd. , 2008 , Article)In this article we study the convergence of the overlapping Schwarz wave form relaxation method for solving the convection-diffusion equation over multi-overlapped subdomains. It is shown that the method converges linearly ... -
Overproduction of Delta-Endotoxins by Sporeless Bacillusthuringiensis Mutants Obtained by Nitrous Acid Mutagenesis
( Springer-Verlag , 2011 , Article)Asporogenic and oligosporogenic Bacillus thuringiensis mutants having the ability to overproduce insecticidal crystal protein were generated by using nitrous acid (50 mg/ml), as chemical mutagenic agent. Insecticidal crystal ... -
An overview of brine management: Emerging desalination technologies, life cycle assessment, and metal recovery methodologies
( Elsevier , 2021 , Article Review)This study examines which management methods are the most recent and advanced in managing rejected brine generated from desalination plants. It also provides up-to-date information regarding the most adequate technologies ... -
An overview of heavy metals toxicity in plants, tolerance mechanism, and alleviation through lysine-chelation with micro-nutrients—A novel approach
( Springer , 2022 , Article Review)Abstract: Plants must adapt themselves to the prevailing conditions for their survival, resulting in the acquisition of a wide range of metal tolerance mechanisms. Although many metal elements are essential for the growth ... -
An overview of Zika virus genotypes and their infectivity
( Sociedade Brasileira de Medicina Tropical , 2022 , Article Review)Zika virus (ZIKV) is an enveloped, single-stranded RNA arbovirus belonging to the genus Flavivirus. It was first isolated from a sentinel monkey in Uganda in 1947. More recently, ZIKV has undergone rapid geographic expansion ... -
Oxidative degradation of tannic acid in aqueous solution by UV/S2O8 2- and UV/H2O2/Fe2+ processes: A comparative study
( MDPI AG , 2019 , Article)Tannic acid (TA) is a major pollutant present in the wastewater generated from vegetable tanneries process and food processing. This work studied TA degradation by two advanced oxidation processes (APOs): UV irradiation ... -
Oyster oscillator: a novel mega-stable nonlinear chaotic system
( Springer , 2021 , Article)Designing novel mega-stable chaotic oscillators has been a hot topic of research lately. In the current paper, a two-dimensional mega-stable oscillator is presented. The oscillator has a vast amount of coexisting limit ... -
P. putida as biosorbent for the remediation of cobalt and phenol from industrial waste wastewaters
( Elsevier B.V. , 2020 , Article)The current work focused on the feasibility of treating industrial wastewater containing phenol and cobalt (Co) by adsorption, biosorption, and bioadsorption to determine the effectiveness of each technology. To study the ... -
(−)-Paniculatol, a new ent-labdane bromoditerpene from Laurencia paniculata
( Elsevier Science Ltd. , 1997 , Article)(−)-Paniculatol, 1, an unusual tricyclic bromoditerpene belonging to the ent-labdane series has been identified in the red alga Laurencia paniculata collected on Qatari coasts, Arabian Gulf. The structure displays an unusual ... -
Parallel LQP alternating direction method for solving variational inequality problems with separable structure
( Springer International Publishing , 2014 , Article)In this paper, we propose a logarithmic-quadratic proximal alternating direction method for structured variational inequalities. The predictor is obtained by solving series of related systems of nonlinear equations, and ... -
Parameter estimation in a new chaotic memristive system using ions motion optimization
( Springer Verlag , 2019 , Article)In this paper, a new four-dimensional nonlinear oscillator is introduced. This oscillator is memristive and can exhibit chaotic behavior. A complete dynamical analysis is done on each parameter of this system by the help ... -
Parametric Model Based on Imputations Techniques for Partly Interval Censored Data
( Institute of Physics Publishing , 2018 , Conference Paper)The term 'survival analysis' has been used in a broad sense to describe collection of statistical procedures for data analysis. In this case, outcome variable of interest is time until an event occurs where the time to ... -
Paraviral cutaneous manifestations associated to SARS-CoV-2 Omicron variant
( Taylor and Francis Group , 2022 , Article)Background: The spreading of the SARS-CoV-2 Omicron variant is probably due to its increased transmissibility and ability to escape from neutralising antibodies. Cutaneous manifestations have been reported after infection ... -
Parcellating cognitive heterogeneity in early psychosis-spectrum illnesses: A cluster analysis
( Elsevier B.V. , 2018 , Article)Cognitive impairment is argued to represent a core feature of psychosis-spectrum illnesses. However, within-diagnosis heterogeneity is common, and risk factors for poor cognition remain to be examined after statistically ... -
