ENA was recently used for remote on-line corrosion monitoring of carbon steel electrodes in a test loop of a surge water tank at a gas storage field. An experimental design and system for remote ENA and collection of electrochemical impedance spectroscopy (EIS) data (Fig. 13) have been presented elsewhere. In the gas storage field, noise measurements were compared with electrode weight loss measurements. Noise resistance (R ) was defined as... 

Basic experimental designs for field soil dissipation studies... 

The first step in a wildlife exposure assessment is to document the occurrence and persistence of a pesticide in the study area throughout the study duration. Several articles in this book describe the experimental designs and best practices to conduct field crop and environmental dissipation (air, soil and water) studies. This article presents methods to quantify spatial and temporal distributions of pesticide presence in ecosystems following normal application and resultant exposure of nontarget wildlife. 

It is clear that one of the major challenges in the experimental studies of free radicals is the preparation of radicals. The experimental designs (production of radicals and detection of radicals and photoproducts) are largely dependent on the particular radicals of interest. Nevertheless, many approaches have been taken, as seen in this review, to study the free radical photodissociation, and a great number of systems have been examined during the last couple of years. The sophistication in the experimental studies of free radical photochemistry has reached the level that has been available for the stable molecules. State-to-state photodissociation dynamics of free radicals have been demonstrated for a few small systems. Many more advances in the field of photodissociation dynamics of radicals are expected, and it is hoped that a more systematic and sophisticated understanding of free radical photochemistry can be developed.

Cost will be the primary controlling factor In the experimental design In essentially all cases. The cost of obtaining the entire population of possible measurements Is prohibitive. The field study design must select a subset which Is representative of the population within definable confidence limits and which can be obtained within the constraints of existing resources. 

Tennant, like Wollaston, enjoyed the esteem and friendship of the great Swedish master, Berzelius, who paid him a visit in the summer of 1812. Together they rode on horseback to inspect the 100-acre experimental oat field in which Tennant had mixed lime with the soil in decreasing ratio from one end to the other (31). After he had shown Berzelius the tall, well-developed oats at the highly limed end and the sickly plants at the other end of the field, they visited the limekiln which Tennant himself had designed (30). 

Data Treatment. The experimental design of sample collection did not permit statistical comparison of the collection efficiencies of filter combinations versus concentrated HNO3 impingement. The laboratory chamber was designed to simulate field conditions and not provide a "closed" system in which the concentrations of Plictran could be controlled. 

Several thousand papers using experimental designs have been published. We summarise in Table 2.34 the most important in our field from 1999 to 2008. Quite surprisingly, the number of papers using simplex methods to optimize analytical procedures is not so large and, so, our review started at 1990 (see Table 2.35). For older references on simplex applications see Grotti [143] and Wienke et al. [144].
