The treatment of bleach effluent from pulp and paper Industry for COD, colour and AOX removal was investigated using Ultra violet/Hydrogen peroxide process photocatalysed by Titanium dioxide. The Ultra violet / Titanium dioxide process was able to remove 48% and 37% of COD and colour. The Ultra violet / Hydrogen peroxide process was able to remove 52% and 59% of COD and colour. The combined pro...

We report the first efficient trapping of rare-earth Yb atoms with a high-power violet laser diode (LD). An injection-locked violet LD with a 25 mW frequency-stabilized output was used for the magneto-optical trapping (MOT) of fermionic as well as bosonic Yb isotopes. A typical number of 4 × 10 atoms for Yb with a trap density of ∼ 1 × 10/cm was obtained. A 10 mW violet external-cavity LD (ECLD...

Borzani and Vairo (1959) reported that grampositive and gram-negative microorganisms are fundamentally different with respect to crystal violet adsorption. They claimed that the binding of crystal violet by gram-positive cells followed the Freundlich and the Langmuir adsorption laws; whereas the binding of crystal violet by gram-negative cells did not follow any known adsorption law. The presen...

Basic Violet 14, Direct Red 28 and Acid Red 26 are classified as carcinogenic dyes in the European textile ecology standard, despite insufficient toxicity data. In this study, the toxicity of these dyes was assessed in a zebrafish model, and the underlying toxic mechanisms were investigated. Basic Violet 14 and Direct Red 28 showed acute toxicity with a LC50 value at 60.63 and 476.84 µg ml(-1) ...

Crystal violet exhibited characteristics of an uncoupler of oxidative phosphorylation, i.e. it released respiratory control, hindered ATP synthesis, enhanced ATPase activity, and produced swelling of isolated rat liver mitochondria. Maximal stimulation of respiration, ATPase activity, and swelling was observed at a concentration of 40 microM. The inhibition of State 3 respiration by oligomycin ...

In a previous communication 1 a selective bactericidal p roper ty possessed by gentian violet was described, and observations were reported to indicate the nature of this chemical affinity as exhibited in a study of a large number of representative bacteria. It was shown that bacteria could be sharply divided into two groups by their behavior toward gentian violet, either by staining the organi...

Background: Autoxidation is considered to be the main route of edible oil deterioration, which produces undesirable odors and flavors (attributed to primary and secondary products of unsaturated fatty acids) during storage and heating. Objective: Antioxidant activities of Zataria multiflora (ZMEO) and Bunium persicum (BPEO) essential oils (EOs) in linseed oil (containing higher ω-3 in vegetab...

In this research, a response surface methodology (RSM) was used to investigate the effects of independent parameters (pH, contact time, temperature, adsorbent dosage, and initial concentration of pollutant), their simultaneous interactions, and quadratic effects on crystal violet adsorption onto two starch based materials in the form of batch experiments. The characterizing results indicated th...

Article history: Received 16 January 2017 Accepted 16 January 2017 Available online 19 January 2017 hypothesis. We are currently doing a clinical trial Minami Aoyama Eye Clinic in Tokyo, Japan using a violet light-emitting desktop light and violet light-transmitting eyeglasses (Clinical trial number: UMIN000021897). Also, a randomized clinical trial is underway on violet light transmitting eyeg...
