Background: Electro-oxidation is developed as an electrochemical method to overcome the problems of  the conventional  decolorization technologies and is an appropriate alternative for the treatment of colored wastewater from various industries. The purpose of this study was to evaluate the efficiency of the electrochemical oxidation process in  removal  of chemical oxygen demand (COD) and Acid...

this publication uses a colorimetric method based on the absorbance spectra of dye solutions to improve on beer’s law when calculating the dye concentrations of a three-component mixture. the performance of the new method is compared with that of beer’s law evaluated at three wavelengths, and beer’s law evaluated at 16 wavelengths. colorimetric method gives the best prediction of dye concentrat...

conclusions there was no significant statistical difference between mta and cem cement in sealing ability (p > 0.05). results the mean apical penetration of dye in the mta group was 0.94 mm while in the cem cement group this was 1.17 mm. eighty percent of the mta group and 75% of the cem cement group didn’t have any dye leakage. the p level was greater than 0.05 (0.592). materials and methods e...

Profi le Howard Feldman: master of dementia Throughout his career, Howard Feldman has contributed to the characterisation of the natural history of the dementias, but he has also been involved in clinical trials and research on biomarkers, including his work on melanotransferrin and within the Alzheimer's Disease Neuroimaging Initiative. More recently, he was part of a research team that showed...

Orthodontic adhesive is often left on the tooth surface when a multibracket appliance is debonded, and it is difficult to remove because its colour is similar to that of the tooth. If the adhesive changed colour during debonding, residual adhesive could be more easily removed. This in vitro study evaluated the usefulness of adhesive mixed with a small amount of fluorescent dye for clinical orth...

The present study was undertaken to compare five laboratory diagnostic tests for sub-clinical mastitis in cattle and buffaloes and to compute cost, time taken by each test and its ranking for availability, adoptability, interpretability and sensitivity. There were 352 cases with each test type viz. California Mastitis Test (CMT), White Side Test (WST), White Side + Dye (WSTD), Surf Test and Sur...
