grease
The results showed that the lamellar liquid crystal and the mixed system showed higher load carrying capacity relative to the commercial grease.
      
The derived kinetic equation for tribochemical grease degradation allows one to predict, with a practically acceptable accuracy, the service life of the friction unit and the advancement and chemism of tribochemical processes.
      
An increase of the valence angle in the CH2 groups of alkane molecules is detected when the crystallites in samples of ceresin grease melt on an aluminum substrate.
      
These chelates are volatile enough to be analysed by gas chromatography and the separation of Th and U complexes is performed at 170°C on a column filled with glassbeads coated with DC-QF 1 silicone grease.
      
We studied direct drug effects on rat abdominal vagus nerve using the grease-gap technique.
      
The grease gap technique of the isolated abdominal vagus nerve is a useful technique for screening the emetic agents.
      
The paper presents the composition and the process of production of the new grease containing exclusively environmentally safe biodegradable components such as rape oil, vegetable oil tar, inedible fat as well as natural and artificial silicates.
      
The grease is operable within 0-160°C and intended for friction units of light and food industry equipment.
      
Using the developed machine and the testing procedure, a lubricant grease Litol-24 was subjected to testing with additions of solid lubricants (graphite powder and MoS2) and organic dopes containing P, Cl, S, and O.
      
It is established that the introduction of these additives into the HF80 grease reduces the friction coefficient considerably (3-7 times) when in contact with snow in temperatures below zero (-15°C) in the laboratory conditions.
      
This is due to the drop in heat conductivity of the modified grease, because the orienting effect of the liquid-crystal molecules produces an anisotropic structure in the acquired lubricating layer.
      
The effectiveness of the studied mesogenic modifiers depends on their molecular structure and concentration in the grease.
      
Using two different experimental methods at the UCN source of the Institut Laue-Langevin we have investigated both the energy-gain and the energy-loss side of quasi-elastic UCN scattering on Fomblin grease coated walls.
      
Leaves pressed between sheets of glass sealed with grease elicited a strong landing response, showing that odors are not required to elicit landing.
      
Any contaminating smooth muscle cells or fibroblasts are ringed with a grease pencil and not removed when the cells are subcultured.
      
The values of iodine, saponification and acid pH, composition of fatty acids of grease were analyzed both chemically and by apparatus.
      
The chambers had removable barriers so that the fluid bathing the ganglia was separated from that bathing the nerve trunks by inert silicone grease seals.
      
Protecting pressure gauges with grease in high temperature facilities
      
A study was undertaken to this purpose, and a procedure for mounting and covering the gauges with a protection layer of grease has been developed.
      
A grease-gap extracellular recording technique was used.
