Introduction
Whenever two materials are joined an interface is created.
Junction can be treated as a sandwich material which can modulate the transport properties of individual materials.
The easiest set up for low melting materials is the resistive heating method.
An interface is defined as the region exhibiting properties differing from the joined materials.

The obtained results showed that power loss in polymer bearings is at least six times less than in conventional white metal ones indicating that polymer journal bearings are more energy efficient and environmentally friendly [15].
Materials and Method An in-situ study is carried out on board of several ships of different types; i.e. container ships, general cargo ships, and bulk carrier ships.
In 1988, Pearl presented the most important application of Bayes formula, called “Bayesian Networks” (BN) and which has a wide application in several fields of science, such as medicine, systems security analysis, image treatment and decision-making [32].

Abstract: The present study is related to entropy analysis during magnetohydrodynamic (MHD) boundary layer flow of a viscous incompressible electrically conducting fluid past a stretching cylinder with convective heating in the presence of a transverse magnetic field.
Therefore while the transverse magnetic field serves to decelerate the fluid flow i.e. achieve flow regulation, the counter-productive effect of heating the fluid is also caused and this requires smart use of magnetic fields so that desired material characteristics are achieved and excessive temperatures not generated.

"Modern enterprise behaves extrovert, designs and uses organizational structure as a component of its strategic capabilities, and tests the quality by meeting demands for the company to respond quickly to opportunities and threats in the environment (it is flexible), that is able to successfully coordinate the activities in order to operate effectively (and achieve the purpose of existence and defined goals), but also to operate efficiently (optimal ratio between input and output)." [3] From the above observation it can be seen that the organizational structure also depends on the choice of business strategy i.e. decision made by the manager on what the organization will focus (the possibility of performing a particular job) and how they will use their resources (human and material).
The organizational structure is clearly one of a kind, by the nature it is a complex creation, which is created and shaped to achieve the goals of the organization and thus regularly includes both actors of work and their mutual relations, a compact system of schedules of the available human and material resources of an organization, together with their mutual (overall) relationship and connections.
In it, placed and appropriately deployed, are all the resources, all the material and human elements of the organization and through mainly their individual and group guidance towards achieving the goals of the organization is performed.
