Track trace

In these tests, EA 3580 produced somewhat more impairment in performance of Track Tracing Accuracy (Fig. 34) than in Track Tracing Speed (Fig. 35), suggesting that physical competence may be more resistant than cognitive functions to the effects of anticholinergic drugs with high relative central potency. 

There has been considerable interest in the determination of ions at trace levels as, for example, in applications need high-purity water as in semiconductor processing and the determination of trace anions in amine treated waters. For this investigation, we will define "trace" as determinations at or below 1 pg/1 (ppb) levels. The Semiconductor Equipment and Materials International (SEMI) recommended the use of IC for tracking trace ionic contaminants from 0.025 to 0.5 pg/1 [18]. In addition, the Electric Power Research Institute (EPRI) has established IC as the analytical technique for determining of trace level concentrations of sodium, chloride and sulfate down to 0.25 pg/1 in power plant water [19]. 

At Charles Sturt University (CSU), Australia, a multidisciplinary research group has been interested in the chemical basis for plant allelopathy for a number of years. One major impediment to progress has been the difficulty in tracking trace amounts of biologically active substances within complex plant and soil matrices. Recent improvements in bench-top chromatography-mass spectrometry have, however, greatly improved this situation.3,5... 

An example of a practical application of the method is the independent platform Respect-Code . This traceability system helps brands to increase trust with their consumers, as well as allowing them to enhance collaboration with supphers. It offers a smart risk management tool that shows what is happening across the supply chain and identifies room for improvement (www.respect-code.org). Another practical example of traceability systems is the MADE-BY Track Trace system that follows the trail of the clothes. From the MADE-BY code in the garment, the consumer can find out where the garment was made and by whom (http //www.made-by.org/).

As stated previously, traceability is fundamental to establishing and eliminating the root cause of nonconforming product and therefore it should be mandatory in view of the requirements for Corrective Action. Providing traceability can be an onerous task. Some applications require products to be traced back to the original ingot from which they were produced. In situations of safety or national security it is necessary to identify product in such a manner because if a product is used in a critical application and subsequently found defective, it may be necessary to track down all other products of the same batch and eliminate them before there is a disaster. It happens in product recall situations. It is also very important in the automobile and food industries in fact, any industry where human life may be at risk due to a defective product being in circulation. 

Radioisotopes are used as long-lasting power sources, to study the environment, and to track movement. They are used in biology to trace metabolic pathways, in chemistry to trace reaction mechanisms, and in geology to determine the ages of rocks.

Given a precise notation for abstractions, you can determine whether a given design conforms to the abstraction and can trace how each piece of an implementation realizes each requirement. Tools can help keep track of the propagation of changes in either requirements or implementations.
