Against this, however, greater skill, ingenuity and manpower was necessary to maintain and operate an ageing machine park short on parts, lubricants and other essentials.
This suggests mainly undegraded light aviation fuel mixed with heavier fuels and lubricants.
Frequent use of topical lubricants together with antibiotic drops or ointment for any associated bacterial contamination will relieve most symptoms.
The fuels and lubricants required for the growing national machine park were mostly imported as well, as was the bulk of fertilisers and irrigation equipment.
Capillary instability is rapidly stabilized by using heavy lubricant.
First, the envelope of the lubricant is marked on the imaginary hexagonal mesh.
Thin films are also used as lubricant layers for the flow of crude oil in pipes and channels.
Figure 7 shows that the flow is stable when the lubricant is heavier than the core fluid and unstable when lighter.
