If the spheres are of identical material, then γ12 = 0.
It is an equilibrium theory, it is only valid for short range surface forces and compliant materials (Tabor parameter greater than unity [7]), and provides no guidance on attractive forces prior to contact.
The rubber material was dicumyl peroxide cured synthetic polyisoprene.
The JKR equation that emerged from the work has found use for the interpretation of adhesion results for a wide range of materials and nanotechnological setups.

Introduction Currently, the market demand for using natural products is increasing, in which extracts and compounds with natural materials for beauty are also paid more attention.
And the research works related to the development of personal care products from the source of coconut oil in the locality of Ben Tre province are still limited in the results published in prestigious domestic and national scientific journals.
Thus, with the potential of coconut oil sources available at Ben Tre, this research has been active in the source of raw materials to produce natural cosmetic products from coconut oil through the saponification of coconut oil.
Material and Methods Raw materials and chemicals.
Acknowledgements This study was supported by Ben Tre Department of Science and Technology, Ben Tre Province, Vietnam under the grant number 1136/HĐ-SKHCN.

The transfer process was done so that all the structure properties, such as geometry, materials, assigned loads, frame and shell sections, and joint constraints, remained the same.
The structural members, such as columns, beams, and conventional braces, are made of steel material of grade Q345, with a nominal yield strength, fyk, of 345 MPa.
The yield deformation was calculated based on elastic modulus of steel, Es, and the yield force, which was computed using the material nominal yield strength, fyk = 235 MPa.

Dentin exhibits a behavior like a functionally graded material with properties dependent on tubule density and orientation.
However, Eq. (5), properly related to isotropic materials, is not the correct relationship to calculate dentin Poisson’s ratio.
FIMEC (Flat-top cylinder Indenter for MEchanical Characterization) is an instrumented indentation technique, developed by one of the authors to test metallic materials on a local scale.
The interpolating function consists of two exponential terms with relaxation times τ1 and τ2, which describe two different mechanical processes typical of porous materials.

To estimate the consumer attitude to the technical and economic features of the product and optimize the dialogue between the consumer and the producer of the science-intensive we suggest a method which involves the following stages.
Although z1 production (M-138/2 (YuMZ)) and z4 production (JOY (USA)) have similar aggregates of expert assessments but the high degree of compatibility of z1 production (M-138 /2 (YuMZ)) with the parameters “high quality of science-intensive products” and “high production efficiency” make it more preferable.
