Vegetable oils as lube basestocks: A review
African Journal of Biotechnology, 2015 The depletion of the world’s crude oil reserve, increasing crude oil prices, and issues related to conservation have brought about renewed interest in the use of bio-based materials. Emphasis on the development of renewable, biodegradable, and environmentally friendly lubricants has resulted in the widespread use of natural oils and fats.

Abductive and Consistency-Based Diagnosis Revisited: a Modeling Perspective
, 2000 Diagnostic reasoning has been characterized logically as consistency-based reasoning or abductive reasoning. Previous analyses in the literature have shown, on the one hand, that choosing the (in general more restrictive) abductive definition may be ...

The use of oil for in-flight flow visualization [PDF]
Oil was used to visualize inflight aerodynamic characteristics such as boundary layer transition, shock wave location, regions of separated flow, and surface flow direction. The technique, which is similar to wind tunnel oil-flow testing, involves an oil

Polymer International, EarlyView.An overview and categorization of man‐made per‐ or polyfluoroalkyl substances (PFASs) including low‐molar‐mass and high‐molar‐mass fluorochemicals, and their international regulations is presented. Though certain PFASs are toxic, bioaccumulative and cross the human cellular membranes, others, such as fluoropolymers, are safe, reliable and involved in ...

Performance tests with a 4.75 inch bore tapered-roller bearings at high speeds [PDF]
The tapered-roller bearings were tested at speeds to 15,000 rpm which results in a cone-rib tangential velocity of 130 m/sec. (25,500 ft/min). Lubrication was applied either by jets or directly to the cone-rib, augmented with jets.
