KINETICS AND MECHANISM OF AERIAL OXIDATION OF HYDROQUINONE IN A DEVELOPER SOLUTION AND DETERMINATION OF DEVELOPER'S HALF-LIFE AT 20°C
The aerial oxidation of hydroquinone in a freshly prepared developer solution at 20°C has been studied through the measurement of concentration changes by a spectrophotometric method. The concentration of consumed hydroquinone is directly proportional to time, and the equation tIl2 = C, / 0.0786 was obtained to calculate the half-life of the developer. In this equation, the half-life is in ...
متن کاملEvaluation of Intra-articular Colloidal Gold Au 198 in the Treatment of Presistent Knee Effusions.
In the management of persistent knee effusions, synovectomy may be useful but surgical removal is often far from complete and recurrences are common. The present study reports an attempt to produce a radiation synovectomy, using the principle that colloidal Au 198, when injected into the knee joint, would behave like other particles and localize on the synovial membrane. Au 198 has a half life ...
متن کاملUncertainty Measurement for Ultrasonic Sensor Fusion Using Generalized Aggregated Uncertainty Measure 1
In this paper, target differentiation based on pattern of data which are obtained by a set of two ultrasonic sensors is considered. A neural network based target classifier is applied to these data to categorize the data of each sensor. Then the results are fused together by Dempster–Shafer theory (DST) and Dezert–Smarandache theory (DSmT) to make final decision. The Generalized Aggregated Unce...
متن کاملImpact of Pollution Location on Time and Frequency Characteristics of Leakage Current of Porcelain Insulator String under Different Humidity and Contamination Severity
One of the important factors influencing outdoor insulators performance is pollution phenomenon. The pollution, especially during humidity condition, reduces superficial resistance of insulator and lead to a flow of Leakage Currents (LC) on the insulator surface, which may result in total flashover. The LC characteristics are affected by parameters such as nature and severity of pollution. Loca...
متن کاملA review of structural properties, metabolic function and measurement of peroxidase activity
The production of reactive oxygen species occurs during the natural metabolism of oxidative-breathing cells. Among reactive oxygen species, hydrogen peroxide is more dangerous to cell life due to its long half-life, but it is meanwhile an important regulatory molecule in redox signaling in living things. Peroxidases are one of the key antioxidant enzymes that are widely distributed in nature an...
