The organic dyes directly pollute the soil, water, plants and all living systems in the environment. In the present investigation, adsorption of brilliant green dye on silica from aqueous solution was studied. The dye adsorption mechanism was studied on the basic surface of silica. The adsorption parameters were optimized to maximum adsorption. The adsorption mechanism of brilliant green on sil...

Jute is one of the available and cheap cellulosic fibers that can be printed used instead other materials may relatively high in price. bio-degradable raw therefore does not cause harm to environment along with advantages because its many advantages, it called golden fiber. Textile printing practice applying color distinct patterns or designs sharp outlines. Inappropriately fibers, tied fiber, ...

Flash photolysis experiments of the photoreduction of oxonine, thionine, and selenine showed that for all three dyes the rate constant of the electron transfer process between the reducing agent allylthiourea and the acid triplet form is considerably higher than that of the corresponding reaction with the basic form. The higher reactivity of the acid triplet form can be related to its higher re...

Green macroalga Caulerpa lentillifera was found to have reasonable adsorption capacity for basic dyes, Astrazon Blue FGRL (AB), Astrazon Red GTLN (AR), and Astrazon Golden Yellow GL-E (AY). The initial dye concentration was in the range of 100-1,800 mg/L. The dried algal sorbent was ground and sieved into 3 sizes: S (0.1-0.84 mm), M (0.84-2.0 mm), and L sizes (larger than 2.0 mm). For all condi...

In the course of a careful study of a long series of livers, both cirrhotic and otherwise, we have in the specimens examined, with scarce an exception, encountered larger or smaller numbers of minute bodies, and the more we have studied them the more assured we have become that these are bacterial in nature. Under t h e ordinary 1/12th immersion lens and by the usual methods of staining these m...

The purpose of this study was to evaluate the effects of both marginal fit and cementing with different luting agents on the microleakage of all-ceramic crown systems. Thirty-six extracted upper central incisors were prepared for full-coverage crowns and were divided into three groups. Group 1: CAD/CAM-fabricated ZrO2, Group 2: Heat-pressed lithium-disilicate, and Group 3: Cast Cr-Co copings as...

AIM Verify the use of immunohistochemistry as a method to measure all forms of elastic fibers at human vocal folds. STUDY DESIGN Transversal cohort. MATERIAL AND METHOD We collected vocal folds following these criterion: age between 25 and 40, Caucasian men, dead by gun shot, within 12 hours of death, without instrumentation of the larynx or suspicion of neck injury and without mucosal lesi...
