Introduction
In physics, cases are known when classical theory contradicts to experimental data.
The electromagnetic induction’s law reads that induction’s electromotive intensity Ei , i.e. the effort on transferring the single positive charge along a closed loop with length performed by magnetic field is equal to the magnetic flux’ change rate in a time unit ( - dФmdt), where the negative sign means the reduction of the magnetic field’s energy by means of which the effort is performed: Ei=-( dФmdt )

A scanning interval of 2q= 0.02° was adopted and the data were taken at room temperature in the 2q range of 20-80°.
Broadening and intensity reduction of most of the peaks during milling are due to refinement of crystalline size of the powder and an increase in atomic level strains.

A number of minor problems and errors has been occurred associated with data sources, their type and displaying of results.
Next, a series of tests have been carried out which showed a significant reduction in the program speed and the error-free operation, and besides the amount of resources level taken on the execution of algorithms has significantly decreased as compared with the implementation of the model in matlab framework.

c-3D mode (3/4) of cold extrusion forming
Pretreatment Process of Cold Extrusion
The reduction of area of injection head is 25%, meeting the requirements that AISI-1035 steel single extrusion maximum allowable deformation is 55%.
After the pretreatment, *.DB format data files are generated, and exit the pretreatment module.

The transmission data have been used for evaluating the band-gap energy value of the ZnO films.
The decrease in band gap of ZnO films may be attributed to the improvement in the crystalline quality of the films along with reduction in porosity and increase of grain size [4].

Although comparisons between the numerical[5,6,9,11] and experimental[3] results showed some similarities, it may be doubted as the assumed input data for calculations were quite different from the experimental ones.
The reduction of filmthickness may possibly lead to a lubrication failure.

It is concluded that the thermal conductivity, viscosity and density of the nanofluids increases with the concentration, meanwhile the surface tension shows a slight reduction.
Thermocouples are affixed over the heat pipe surfaces and connected with a data logger which is connected with a personal computer to continuously monitor and record the changes in the temperature values at each location.
