Pure random orthogonal search (PROS): A plain and elegant parameterless algorithm for global optimization
( MDPI AG , 2021 , Article)A new, fast, elegant, and simple stochastic optimization search method is proposed, which exhibits surprisingly good performance and robustness considering its simplicity. We name the algorithm pure random orthogonal search ... -
Purification and biochemical characterization of a novel thermostable protease from the oyster mushroom Pleurotus sajor-caju strain CTM10057 with industrial interest
( BMC , 2019 , Article)Background Proteases are hydrolytic enzymes that catalyze peptide linkage cleavage reactions at the level of proteins and peptides with different degrees of specificity. This group draws the attention of industry. More ... -
Purification and characterization of a new Bacillus thuringiensis bacteriocin active against Listeria monocytogenes, Bacillus cereus and Agrobacterium tumefaciens
( Springer Science , 2011 , Article)This study reports on the identification, characterization and purification of a new bacteriocin, named Bacthuricin F103, from a Bacillus thuringiensis strain BUPM103. Bacthuricin F103 production began in the early exponential ... -
Purification and characterization of an extracellular phenol oxidase from culture filtrates of Pyricularia oryzae
( NRC Research Press , 1996 , Article)Extracellular phenol oxidase activity was characterized and compared in Pyricularia oryzae wild-type and albino cell types to determine if this phenol oxidase was responsible for lack of melanization in the albino culture. ... -
Purification of colloidal oil in water emulsions by cationic adsorbent prepared from recycled polyethylene waste
( Elsevier , 2024 , Article)This study deals with removing crude oil droplets from colloidal oil in water emulsions. The target was the development of efficient adsorbents for the tertiary treatment of industrial-produced water (PW). The novel adsorbent ... -
Purification of emulsified oily polluted waters with modified melamine foams
( Elsevier , 2023 , Article)Oil and gas industry operations produce tremendous amounts of wastewater (produced water; PW). Tertiary treatment of the PW in the final treatment stage is challenging due to the presence of colloids with sizes < 500 nm ... -
PURIFICATION OF PRODUCED WATER BY CUTTLEFISH BONE ADSORBENTS
(2024 , Master Thesis)The cuttlefish bone powder (CFB) which is mostly composed of calcium carbonate was prepared, characterized, and modified to use it for the purification of emulsified oil/water mixtures from produced water. The focus was ... -
Purpose of the book and editorial perspectives
( Springer International Publishing , 2015 , Book chapter)Engineering and engineering education play an essential role in the Middle East. Global debates regarding roles of engineering and required transformations in engineering education have been extensive during the past few ... -
Pursuing Frugal Innovation for Sustainability at the Grassroots Level
( Cambridge University Press , 2021 , Article)Firms are often criticized for their reluctance to embrace sustainability in their business strategies. Frugal innovation is a recent concept that represents a new way for firms to serve underserved customers in developing ... -
The push for practical legal skills education in Qatar: Results from an externship program
( Hamad bin Khalifa University Press (HBKU Press) , 2016 , Article)For decades, educators across the world have been advocating for educational reform that would increase the number of practical skills courses included in traditional legal education. In 2011, Qatar University College ... -
PV power prediction in Qatar based on machine learning approach
( Institute of Electrical and Electronics Engineers Inc. , 2018 , Conference Paper)PV output power is highly sensitive to many environmental parameters, hence, power available from plants based on this technology will be affected, especially in harsh environments such that of Gulf countries. In order to ... -
PV/Battery Grid Integration Using a Modular Multilevel Isolated SEPIC-Based Converter
( MDPI , 2022 , Article)Photovoltaic (PV) plants can be built rapidly when compared with other conventional electrical plants; hence, they are a competent candidate for supplying the electricity grid. The output power of the PV modules can be ... -
PVA/chitosan/silver nanoparticles electrospun nanocomposites: Molecular relaxations investigated by modern broadband dielectric spectroscopy
( MDPI AG , 2018 , Article)In this study, we used broadband dielectric spectroscopy to analyze polymer nanofibers of poly(vinyl alcohol)/chitosan/silver nanoparticles. We also studied the effect of incorporating silver nanoparticles in the polymeric ... -
PWM scheme for dual matrix converters based five-phase open-end winding drive
( IEEE , 2013 , Conference Paper)The paper present simple carrier-based pulse width modulation scheme for three to five-phase matrix converters feeding a five-phase machine from both ends. The two matrix converters feeding a five-phase induction machine ... -
PyGOP: A Python library for Generalized Operational Perceptron algorithms
