Deep understanding

With the reference block method the distance law of a model reflector is established experimentally prior to each ultrasonic test. The reference reflectors, mostly bore holes, are drilled into the reference block at different distances, e.g. ASME block. Prior to the test, the reference reflectors are scanned, and their maximised echo amplitudes are marked on the screen of the flaw detector. Finally all amplitude points are connected by a curve. This Distance Amplitude Curve (DAC) serves as the registration level and exactly shows the amplitude-over-distance behaviour" of the reference reflector for the probe in use. Also the individual characteristics of the material are automatically considered. However, this curve may only be applied for defect evaluation, in case the reference block and the test object are made of the same material and have undergone the same heat treatment. As with the DGS-Method, the value of any defect evaluation does not consider the shape and orientation of the defect. The reference block method is safe and easy to apply, and the operator need not to have a deep understanding about the theory of distance laws. [Pg.813]

The widespread use and applicability, however, can be directly attributed to the deep understanding of the fundamental properties associated with these elements and their attendant compounds. The fundamental research conducted with these elements forms the foundation upon which all applications and utility are built. The present Structure and Bonding volume is part of a three-part series focused on fundamental, biological, and applied aspects of the group 13 elements. It will showcase four new areas of fundamental work that will either grow in importance in the coming years, or provide new insight into potentially new areas. [Pg.178]

The job of mentoring scheme co-ordinator is not particularly easy - far from it. It demands a deep understanding of the nature and d)mamics of mentoring, and a remarkable store of patience, tenacity and political skill. Yet we have never... [Pg.345]

Irons-phenyl, alkyl diazenes (2), peresters (3) and hydrocarbons (4). These equations are intended to be used for their predictive value for applications especially in the area of free radical polymerization chemistry. They are not intended for imparting deep understanding of the mechanisms of radical forming reactions or the properties of the free radical "products". Some interesting hypotheses can be made about the contributions of transition state versus reactant state effects for the structure activity relationships of the reactions of this study, as long as the mechanisms are assumed to be constant throughout each family of free radical initiator. [Pg.426]

For situations of high chemical risk, this book is at the level of preliminary analysis of risk (hence its title), that is to say, at the first stage of risk inventory, these linked to chemical products and their implicit chemical reactions. It brings together substances and procedure. On the other hand, a deep understanding of work routines, implicit in risks other than chemical, is necessary. Certain areas of activity are excluded from this book, notably related to phytosanitary products and equally, the Interaction of chemical products with the environment have been ignored. [Pg.19]

To reach its standards, Millipore positions itself with a deep understanding of its customers research and manufacturing process needs. Once this is achieved, it can offer the tools, technologies and services required. [Pg.272]

That reduces the ground bounce caused by the internal bond wires of the IC, but getting the entire converter to work properly requires a deep understanding of the role played by the PCB, its contribution to ground bounce, noise, and so on. [Pg.49]

The Full Inspection Qption is a surveillance or compliance inspection that is thorough and gives the FDA a deep understanding of the cGMP program in a manufacturing facility. This type of inspection is conducted when the FDA has little knowledge about the facility, such as a new facility or where the facility has a history of noncompliance or when the FDA has doubt about the facility s quality system. The Full Inspection Qption audits at least four systems in the facility, one of which must be the quality system. [Pg.326]

Studies of structure effects on rate have helped substantially to bring researchers to the present deep understanding (72,13) of the mechanism of elimination reactions. Beside stereochemical evidence, successful linear correlations have yielded the desired information. The published series of reactants and correlations are summarized in Table II. The fit of straight lines to experimental data is usually good or very good, and only a few points deviate significantly. Details of the correlations may be found in the original literature here we will concentrate on the values of the slopes. [Pg.163]

This appendix contains the detailed development for the equations that are presented in Chapter 3. Full understanding of these developments is not required for detailed analysis and troubleshooting of the extrusion process. They are presented here for those who desire a deep understanding of the mathematics involved with the screw rotation analysis. Some of the equations and figures are duplicated in this appendix for clarity. The nomenclature used here is consistent with that used earlier. The reader is directed to Chapter 3 for nomenclature. [Pg.687]

Seems like enough, I said, affecting deep understanding. [Pg.154]

A paper airplane and a plasticine car each represent models that might apply, say, in aerospace or automotive research and development. That each approximates the reality of actual aircraft and motor vehicles is intuitively obvious, yet it is immediately clear that neither suffices to explain the theory of their operation or to overcome production problems. Paper and plasticine and even fashion modehng provide types of media that appeal to visual appreciation but fail to provide deep understanding of fundamental issues. To overcome this lack, better media that allow for truer representation and insightful analyses are required. [Pg.250]

Such single-rotation-dependent relationships allowed a computational approach of the versatility or not of the SOAz molecule in dilute solution, and this is of considerable interest for a deep understanding of the wide antitumor activity of this drug, whatever the target may be... [Pg.84]
