A fuzzy model for an increase in locomotive traction force
(Vilnius Gediminas Tech Univ, Vilnius, 2010)
This paper deals with the process of traction force realization described by a suitable mechanical model and is pointed to the adhesion phenomenon as a physical one, i.e. is a suitable factor that the value of traction ...
Microwave sintering improves the mechanical properties of biphasic calcium phosphates from hydroxyapatite microspheres produced from hydrothermal processing
(Springer, New York, 2010)
Starting from two microspherical agglomerated HAP powders, porous biphasic HAP/TCP bioceramics were obtained by microwave sintering. During the sintering the HAP powders turned into biphasic mixtures, whereby HAP was the ...

Opto-Magnetic Method for Epstein - Barr Virus and Cytomegalovirus Detection in Blood Plasma Samples
(Polish Acad Sciences Inst Physics, Warsaw, 2010)
Motivated by characterization of paramagnetic materials (Al, Mn and Ti) and diamagnetic materials (Cu, C and Zn) by opto-magnetic method that is based on light-matter interaction using digital imaging, we present results ...
Influence of internal radial clearance on the ball bearing service life
(Journal of the Balkan Tribological Association, 2010)
External load of ball bearing is transferred from one ring to other one through balls. In the radially loaded bearing all balls are not simultaneously active. Simultaneously active balls participating in load transfer are ...
