Turbulent Shear Flow in Hydrostatic Thrust Bearings
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1980 This paper is concerned with the effects of a turbulent flow in hydrostatic thrust bearings. Applying an equation representing the "low of wall" to the three-dimensional turbulent shear flow, the local velocity distributions between a rotating disk and a fixed wall are calculated as a function of Reynolds number, local pressure gradient and the ratio ...

Journal of Fish Biology, EarlyView.Abstract Triploidy is an effective tool for producing sterile fishes but often results in impaired performance in commercial aquaculture. In light of this, our study compared the physiological response to exhaustive exercise in juvenile diploid and triploid Arctic charr Salvelinus alpinus, a polar species with great potential for aquaculture.

The Effect of Additives on The Performance of HydrostaticThrust Bearings
Al-Khawarizmi Engineering Journal, 2008 The paper is concerned with, the behavior of the hydrostatic thrust bearings lubricated with liquid-solid lubricants using Einstein viscosity formula, and taking into account the centrifugal force resulting from high speed.

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight
Experimental Physiology, EarlyView.Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

Static Properties of Hydrostatic Thrust Gas Bearings With Curved Surfaces
, 1972 The classical treatment of circular, hydrostatic, orifice-regulated thrust gas bearings, in which perfectly plane bearing plates are assumed, is extended to include axisymmetric, but otherwise arbitrary, plate profiles.

Optimum Design of Multiple-Hole Inherently Compensated Air Bearings—Part 1: Circular Thrust Bearings
, 1975 Analyses of inherently compensated hydrostatic gas bearings of three types are presented. The flow model incorporates empirically the partial recovery of the dynamic pressure in the entrance region.
