This paper aims to evaluate the simultaneous adsorption of basic red 2 (BR2) and violet 3 (BV3) in a binary system batch mode using date stones as low cost adsorbents. For both dyes, experimental kinetic data were well fitted by Brouers–Sotolongo model (R =0.99) intraparticle diffusion was controlling step mass transfer mechanisms. The extent found be lower for BR2 (1.13×10 -11 cm /s) than BV3 ...

Removal of Basic Violet 10 (BV-10) from aqueous solution by adsorption on used black tea leaves (UBTL) was studied in batch process. The effects of contact time, pH, concentration and temperature, etc. on adsorption have been investigated. The UV-visible spectrophotometric method was used to analyze BV-10 in solution at constant pH. From the optimization of solution pH, equilibrium adsorption e...

To understand the application of artificial intelligence (AI), specifically Violet™ technology, in determining egg quality for women undergoing oocyte cryopreservation. Retrospective analysis at a fertility clinic. Patients 45yo and younger who underwent cryopreservation used Violet by Future Fertility from Mar 2020 to Apr 2021 were included. Cryopreservation statistics recorded. Oocyte outcome...

In this study the adsorption of Basic Violet, 14 from aqueous solution onto sulphuric acid activated materials prepared from Calophyllum inophyllum (CS) and Theobroma cacao (TS) shells were investigated. The experimental data were analysed by Langmuir, Freundlich and Temkin isotherm models. The results showed that CS has a superior adsorption capacity compared to the TS. The adsorption capacity...

Hearing loss, vestibular disorders and damaged eyesight can be the result of axonal degeneration (Int Jour Ped Otrlaryn, 61:1-15; Inst Opthalm, 7:109-125). Improper functioning of the myelin sheath may be responsible for this degeneration, due to its role in conducting chemical and electrical neural signaling. Investigation of myelin degeneration requires understanding of normal myelinogenesis ...

A potential bacterial strain GSM2, capable of degrading an azo dye Reactive Violet 5 as a sole source of carbon, was isolated from textile mill effluent from Solapur, India. The 16S rDNA sequence and phenotypic characteristics indicated an isolated organism as Paracoccus sp. GSM2. This strain exhibited complete decolorization of Reactive Violet 5 (100 mg/L) within 16 h, while maximally it could...

Prominent progress has been made in nitride semiconductor since high bright blue LED has developed in 1993. It has also expanded to an industry after applied to white LED. These LEDs are produced by the epitaxial growth of nitride semiconductor layers on sapphire (a Al2O3) substrate. On the other hand, recording density in optical disks has increased from CD in 1980s to DVD in latter 1990s. Las...
