About this Topic:

Why -Bio- Hydrodynamic Lubrication Has Important Meaning in Scientific Contemporary Research:

The scientific scope of special issue is concerned in the field of non-conventional lubrication systems for living, deformed, viscoelastic and hypo or hyper-elastic biological and not living mechanical bodies. Moreover can be implemented a new scientific tendencies in mentioned domains and can be anticipated cooperating bio-surfaces lubrication phenomena by pathological or improved non-Newtonian physiological fluid with phospholipid (PL) bilayer in variable time-dependent magnetic induction field, under random unsteady conditions.

The main topics of special issue are as follows:

To indicate some new methods for analytical, numerical and experimental solving the biobearing systems working in non-conventional conditions and environments.

To determinate in experimental and numerical ways, the standard deviations with expected values of random pressure and temperature, friction forces, friction coefficients distributions as well capacity and wear in the gap between two cooperating bio-surfaces.

To develop the active control of bio-fluid, stochastic, laminar, lamellar, two-phase flow in the ultra thin gap between two living, cooperating bio-surfaces restricted with the phospholipid (PL) bilayer.

To gain the knowledge, about the devices, to determine the velocity of moving and cooperating bio-surfaces, and to estimate results of the measurements in micro or nano linear and time level, based on image analysis of nanotechnology.

To gain the measurements and analytical results of the deformations phenomena occurring on the living cooperating biosurfaces in micro, nano-time and volume regions.

Current international level of state-of-the-art in the field of knowledge of slide bio-bearing lubrication with PL bilayer, is high in the field of chemistry, but it does not contains unsteady periodic and impulsive hydrodynamic analysis under random dynamic conditions for genetic or growth deformations of hyper-elastic cartilage surfaces, as well as active control in bio-tribology aspects. Moreover, experimental bio-tribology investigation in this field has not been carried out, yet. Therefore not existing research will be anticipated in special issue.

The research field considered in special issue, will be related to hydrodynamics, theory of elasticity, biomechanics, control systems, cybernetics, theory of vibration, tribology and theory of bio-lubrication. Additionally, it is simultaneously connected with many multidisciplinary domains of knowledge, for example: thermodynamics, bio-fluid mechanics, theory of plasticity, theory of hyper-elasticity, theory of probability, electronic engineering, electrodynamics, mechanics chemistry and mechanics biology. The random theory of conjugated fields spaces can be also applied in the special issue considerations.

The special issue will be preferred a new recent progress of the knowledge about stochastic theory of tribology and hydrodynamic parameters occurring in mechanical bearings and on the real human joint surfaces with a phospholipids bilayer. On the basis of experimental measurements and analytical solutions, the anticipated research are concerning to the determination of the random expectancy values of load carrying capacity, friction coefficient and lubricant fluid dynamic variations for of machinery bearing and human joint.

In special issue will be recommended to indicate the localization of expectancy values of the mentioned tribology parameters for places inside the variable stochastic standard deviation of the bio-bearing gap. Moreover mentioned localization places of expected tribology parameter values included in stochastic standard deviation will be assigned to the concrete probability values.

In the contemporary research of hydrodynamic lubrication problems, mainly the classical constitutive relations for Newtonian synovial fluid flow without magnetic fields and without hyper-elastic properties of joint cartilage, have been confirmed till now.

In this special issue the constitutive relations for non-Newtonian synovial fluid random flow with the magnetic field and hyper- elastic cartilage will be also considered. It is necessary to perform full and general stochastic analyzes of the influence of non-classical, non-isothermal, viscoelastic, pharmacological fluid properties under magnetic field (including experimental measurements).

This special issue is addressed also to such social objectives as quality of life, human health and professional safety. Intrinsic mechanism of joint cartilage or tissue usage will be also recommended here in the aspects of tribology, regeneration and repair in magnetic and acoustic emission fields.

The special issue research is giving an important impact to the development of the new scientific domain, which can be called cyto-tribology, histo-tribology or tribology of cells and tissue. According to the contemporary knowledge such scientific domains are completely new and have been not initiated so far by any scientific centre and in any sphere of tribology and tissue engineering. For developing such scientific domains more knowledge is necessary not only in the field of tissue engineering but also of nano-tribology and thin layer hydrodynamics lubrication.

The gained experience in the field of analytical, numerical and experimental determination of either steady or unsteady distributions of bio- liquid velocity, pressure, capacities, friction forces, friction coefficients, wear of the thin boundary layer lubricating bio-surfaces, permits to apply this knowledge to determine - with the use of analogous methods - the similar parameters but occurring in mechanical devices, for example mechanical slide journal machinery bearings and micro-bearing.

The most excellent slide bearings are the biological bearings in the aspect of material and as regards their construction. Such bio-bearings are shaped by the nature over many thousand years of evolution. Lubricating liquids in bio-bearings change their viscosities under external impulses. Bio-bearings (bio-joints) can adjust themselves to the existing external conditions. These facts inspire to seek similar materials with the similar properties for the machinery bearings and to seek intelligent designs and materials for them, which could change their features during operation and adjust to external working conditions.

It very rarely happens that the experience gained during designing process of machinery bearings is transferred to the construction of bio-joints.

It can be stated that bio-joints and bio-bearings create future call for production of self-regenerating mechanisms and machinery bearings capable of adjusting themselves to the existing external and environmental working conditions.
