all analytical methods are generally based on the measurement of a parameter or parameters which are somehow related to the concentration of the species.an ideal analytical method is one in which the concentration of a species can be measured to a high degree precision and accuracy and with a high sensitivity. unfortunately finding such a method is very difficult or sometimes even impossible.in...

the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...

There are several method for forming bulk material, such as forging, rolling and extrusion. Every of these methods have advantages and dis-advantages of their selves. Forging process is one of the most common of them that include a die, press and in some case heater with controlling system, and has a special place in automotive, military and aerospace industries due uniformity of the final prod...

Despite the large relative mass difference between different Ca isotopes, the isotopic variability of Ca in natural materials is relatively small. Consequently, high-precision Ca isotope analyses are required to accurately resolve Ca isotope fractionation prior to data interpretation. This chapter summarises techniques which are successfully used to digest samples and to purify different types ...

In recent years, it has become evident that it is necessary to systematically and accurately define particle characteristics in order to understand the potential toxicity of nanoparticles to biological systems. The properties that need to be emphasized are size, shape, dispersion, doping, aggregation, functionalization, physical and chemical properties, surface area, and surface chemistry. Rout...
