Voltammetric methods were used to probe the interaction (electrostatic or intercalative) of metal complexes, ML33+/2+ (M = Fe, Co; L = 1,lO-phenanthroline, 2,2'-bipyridine), with calf thymus DNA. Binding constants (Kn+) and binding site sizes (s) were determined from voltammetric data, Le., shifts in potential and changes in limiting current with addition of DNA. The exact magnitude for the par...

This paper is in the form of a Draft Standard, patterned somewhat after the IEEE Standard for Binary Floating-Point Arithmetic [17]. The proposals of this paper are based on a previously published paper [15] which canvasses the need for, and the possibilities of, a standard for general purpose arithmetic. The proposals of this paper relate to one of the representational forms to be used in the ...

To describe the performance of an antenna, definitions of various parameters are necessary. Some of the parameters are interrelated and not all of them need be specified for complete description of the antenna performance. Parameter definitions are given in this chapter. Many of those in quotation marks are from the IEEE Standard Definitions of Terms for Antennas (IEEE Std 145-1983).† This is a...

Purpose: Adolescent idiopathic scoliosis (AIS) is the most common type of scoliosis and the most complex deformity of the spine. The promising results of Schroth and Scientific Exercise Approach to Scoliosis (SEAS), among other methods of exercise therapy, have attracted the attention of many researchers and therapists. However, there is still vague evidence of their effectiveness and the super...

Systems for arranging and describing color include “color spaces” and “color order systems.” In a color space, tristimulus values R, G, and B are computable for every light (every point in the space). In familiar color spaces, such computation makes use of three functions of wavelength (the color-matching functions that define one of the CIE Standard Observers), one function corresponding to ea...
