Example of surface profile produced by 4000 wheel and ELID technique.

The wear of abrasive grains will produce an instability of the grinding performance for dressing technique, while it remains constant for ELID technique. 

Another ELID technique, ELID HI, is introduced (see Figure 9.33). 

Factorial experiments of DSG of alumina ceramics with diamond were carried out in the experimental conditions listed in Table 12.1. Before each experiment, the wheels were dressed to a completely restored cutting ability according to the bond type the vitrified bond wheel was dressed mechanically with silicon carbide superfine dressing sticks, whereas the metal bond wheel was predressed using an electrolytic in-process dressing (ELID) technique.

ELID grinding technique induces compressive surface stress of about 150-400 MPa, with a smaller peak than that outputted by a honing process of 600-800 MPa. 

Carbide pullout of the cBN grits can be avoided by employing ELID dressing technique.

It can be seen that the wear rate of the grinding wheel covered with oxide film is very large, about 10 mm /mm. However, the grinding ratio value for the wheel with oxide film is larger than that of the wheel without oxide film. It can be concluded that ELID-grinding is an efficient technique whenever high productivity is required. 

Detection of cardiotoxicity is via endomyocardial biopsy as well as serial radionu elide angiocardiography (165). Endomyocardial biopsy remains the technique that prO vides the best linear correlation with cardiac toxicity and power of predicting onset of early cardiac failure. Serial radionuclide angiocardiography also has been used in adults, although the technique is not as accurate in children due to the anatomical considera tions that make the image less clear (205). 

The ehromatt raphic method described above represents a major advance in the technique for analysis of bile and has been used successfully to elucidate the biliaiy pattern of excretion of injected estrone sulfate in humans. However, several disadvantages of the procedure can be gleaned upon review of the reports. First, all percentage recoveries were related to the amount of radioactivity elided from the firct (alumina) column. Second, alumina columns are the weakest link in the procedure because of the dangers of irreversible adsorption and side reactions (Neher, 1964) char-...
