(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

Throughout in this text V will be a vector space of finite dimension n over a field K and T : V → V will be a linear transformation. 1 Eigenvalues and Eigenvectors A scalar λ ∈ K is an eigenvalue of T if there is a nonzero v ∈ V such that T v = λv. In this case v is called an eigenvector of T corresponding to λ. Thus λ ∈ K is an eigenvalue of T if and only if ker(T − λI) = {0}‚ and any nonzero element of this subspace is an eigenvector of T corresponding to λ. Here I denotes the identity mapping

Describe the scientific method of research. Be sure to identify the key components‚ providing examples of each. Use external sources to support your answer. The methods of science are the methods of all correct thinking. In all thinking we are concerned with getting and organizing knowledge‚ or with testing‚ applying‚ and developing the knowledge we have already acquired (Jones‚ 1909). According to Zikmund‚ Babin‚ Carr‚ and Griffin‚ “the scientific method is a set of prescribed procedures for
