About this Topic:

In my opinion the proposed special issue can be designed to be implemented 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 anticipated cooperating bio-surfaces lubrication by pathological or improved non-Newtonian physiological fluid with viscoelastic properties 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 calculate, simulate and measure pressure and temperature, friction forces, friction coefficients distributions in the gap between two cooperating bio-surfaces, as well as wear of co-operating surfaces, in experimental and numerical ways.

To develop the active control of bio-fluid flow in the ultra thin gap between two living, cooperating bio-surfaces restricted with the phospholipid bilayer.

To gain the knowledge, on the level of nanotechnology, concerning the utilization of the living and growing materials occurring in moving bio-surfaces.

The considered research field 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, electronic engineering, electrodynamics, mechanics chemistry and mechanics biology. The theory of conjugated fields spaces can be also applied in the considerations.

Current international level of state-of-the-art in the field covered by this special issue, i.e. knowledge of slide bio-bearing lubrication, is high but it does not contain unsteady periodic and impulsive hydrodynamic analysis under random dynamic conditions for deformations of hyper-elastic cartilage surfaces, as well as active control. Moreover, experimental investigation in this field has not been carried out, yet.

In the field of hydrodynamic lubrication research 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 relations for non-Newtonian synovial fluid flow with the magnetic field and hyper- elastic cartilage will be also considered. It is necessary to perform full and general 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 usage is also described here in the aspects of tribology, regeneration and repair.

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 author’s 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.

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 slide journal bearings.

The most excellent slide bearings are the biological bearings in the aspect of material and as regards their construction. Such 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
