The most widely used components in engine oil formulations are the detergent-dispersant alkali additives. In this issue of our journal we are pleased to include the work, which explores the manufacturing methods for producing calcium sulfonate, which is one of these types of components. Ali Celik and Bilsen Besergil of the University of Celal Bayar in Turkey jointly present the paper.

Ali Osman Kurban working at Turkey at Erciyes University, analyses the surface pressures in journal bearings using neural network techniques. Neural networking is also used by other workers at the same university to analyse the efficiency of axial piston pumps operating under various conditions.

From Poland Andrzej Kaz´mierczak of Wroclaw University of Technology reports on his work in computer simulation of the piston ring sealing in an internal combustion engine. Finally, in this issue we are pleased to include the work carried out at the Egyptian Petroleum Research Institute in Cairo. AMA Omar and EMS Azzam describe a development in chromium composite deposition and the related surface properties.

We hope these papers will be of general interest to our readers but we do welcome comments you may wish to make, especially any suggestions concerning items you would like to see included in Industrial Lubrication and Tribology.
