How Visual Stimuli Evoked P300 is Transforming the Brain-Computer Interface Landscape: A PRISMA Compliant Systematic Review.

Non-invasive Visual Stimuli evoked-EEG-based P300 BCIs have gained immense attention in recent years due to their ability to help patients with disability using BCI-controlled assistive devices and applications. In addition to the medical field, P300 BCI has applications in entertainment, robotics, and education. The current article systematically reviews 147 articles that were published between 2006-2021*.

Anoxic treatment of phenolic wastewater in sequencing batch reactor.

Studies were conducted on the anoxic phenol removal using granular denitrifying sludge in sequencing batch reactor at different cycle lengths and influent phenol concentrations. Results showed that removal exceeded 80% up to an influent phenol concentration of 1050 mg/l at 6 h cycle length, which corresponded to 6.4 kg COD/m3/d.

Influence of talc on the properties of polycarboxylate cement.

Zinc oxide, the inorganic component of polycarboxylate cement, was mixed with talc in various proportions from 10% to 50%. These powder mixtures were spatulated with poly(acrylic acid) in three powder to liquid (P/L) ratios of 1:1, 1.5:1 and 2:1 (w/w).

Modified polyalkenoate (glass-ionomer) cement--a study.

Conventional glass-ionomer cements with varying amounts (5-15%) of borax (Na2B4O7.10H2O) as modifier were prepared. These mixtures were spatulated with an aqueous solution of polyacrylic acid with a powder to liquid (P/L) ratio of 1.

Influence of cryolite on the properties of polycarboxylate cement.

Zinc oxide, the inorganic component of polycarboxylate cement, was mixed with the filler cryolite (Na3A1F6) in various proportions that ranged from 10% to 50%. These powder combinations were mixed with polyacrylic acid in three powder-to-liquid ratios of 1:1, 1.5:1, and 2:1 (w/w).
