(DPPH) for estimating antioxidant activity Songklanakarin J. Sci. Technol.‚ 2004‚ 26(2) : 211-219 The use of the stable free radical diphenylpicrylhydrazyl (DPPH) to estimate the activity of antioxidants is reviewed. Current applications of the method are examined‚ particularly the use of the parameter EC50 (substrate concentration to produce 50% reduction of the DPPH). Some recommendations are made as to the most suitable ways of carrying out this assay and evaluating the data produced. Key

To understand the relationships between JIT manufacturing and simultaneous NPD process‚ let’s briefly review the principles of JIT systems. Just-in-Time (JIT) production has been a great force in the world of manufacturing since the early 1980’s. Some of the main benefits of JIT in the

Data structure is the structural representation of logical relationships between elements of data. Data structure mainly specifies the structured organization of data‚ by providing accessing methods with correct degree of associativity. Data structure affects the design of both the structural and functional aspects of a program. Algorithm + Data Structure = Program Data structures are the building blocks of a program. The programmers have to strive hard to solve these problems. If
