We conducted a survivorship analysis of 3234 primary total knee replacements performed at our hospital between 1969 and 1995. Each knee replacement was entered once only. Revision was defined as the end point. Data were collected both from patient records and by postal questionnaire. Eight types of knee prostheses were evaluated with best-case and...

The behaviour of LIX 64N during copper electrowinning from sulphate bath containing Fe3+ was investigated. The results show that LIX 64N alone does not affect either current efficiency or nature of copper deposit. But when LIX 64N is present along with Fe3+ it affects current efficiency, nature of deposit, crystallographic orientation and surface m...
