The tool materials used for joining these base material plates are High Speed Steel (HSS) and High Chromium High Carbon Steel (HCHCr).
The selection of the tool material depends on the material of the workpiece to be welded.
Of the two tool materials, namely HCHCr and HSS, the latter was found to produce good quality sound welds having taper cylindrical threaded pin & 35mm long shoulder tool geometry.

Cybernetics is the art and science of understanding, which connects these two sciences together.
If we consider the electron interaction with matter, unlike other types of radiation used in diffraction studies of materials, such as X-rays and neutrons, electrons are charged particles and interact with matter through the Coulomb forces [17] which means that the incident electrons feel the influence of both the positively charged atomic nuclei and the surrounding electrons, where the wave nature of electron controls its distribution with a wavelength given by De Broglie equation.
This can be the best method to use cybernetics as an art and science of understanding.

Peat is described as naturally occurring, highly organic substance which derived primarily from plant materials [3].
Materials and Methods Peat soils originated from four different districts/region of Sarawak, namely Sibu, Dalat, Bintulu and Miri were reviewed in this paper.
Higher contents of total nitrogen in secondary forest peat soil could be related to its genesis or the origin of the parent materials and the water management [19].
