For example, partial heating of the joining partners should result in a reduction of the process time.
Finally, due to the real tests and the use of the finite-element method, not only a reduction of the process time due to preheating could be confirmed, but also the use of the simulation software for the design of friction welding components could be proven.

In this article discusses the mechanical properties of foam concrete, which submitted based on the experimental data of long force resistance and deformation of compression elements from foam concrete.
Reduction of a measure of an elastic aftereffect at increase in average density for microgranular concrete was significantly less, than for fine grain concrete.
Based on the data of long-term resistance of foam concrete and change of its durability in time, for calculation and projection of designs, estimated performances and coefficients of operating conditions of foam concrete are established in Table 2.
As a result of their comparison to normative data [8], it is established that foam concrete in comparison with other types of light macroporous concrete does not possess the raised long-lived deformable.

The TGA data indicated of 21% functionalization attached to MWCNTs.
The resistivity cell (filled with the MWCNT powder) for the electrical conductivity versus pressure measurements To apply different pressure values, the resistivity cell was placed in Zwick Roell Z2.5 universal material testing machine and coupled with Agilent A34970A data acquisition/switch unit to measure DC electrical resistance.
In the Raman spectra, G band shifted from 1573 cm-1 for neat MWCNTs to 1578 cm-1 due to the functionalization of CNT backbone by high content of –COCl groups, the further functionalization rate decreased as noted by TGA data, which confirmed lower shifting rate of G signal intensity, compared to that of pristine MWCNTs (Table 1).
The study of the electrical conductivity versus pressure (Fig. 4) indicated a reduction of electrical conductivity from 1000 S/m for the MWCNTs to 30 S/m for PEDOT-g-MWCNTs at the maximum compression of the powders (4 MPa).

Research data in the form of secondary data was taken through the Indonesian Geospatial Data Portal of the Geospatial Information Agency and data from the Watershed Management Information System of the Ministry of Environment and Forestry.
By mapping data, we can identify spatial and temporal patterns that may not be visible if the data is only presented in the form of tables or graphs.
Study Area and Data The Latuppa Watershed was chosen as a research area because the research area is always flooded, although the flood rate varies every year.
The data source of this study was obtained from the Indonesian Geospatial Data Portal of the Geospatial Information Agency such as: Shapefile data on slope, soil type, land elevation, rainfall, land use, and river flow density.
The watershed boundary data shapefile is obtained from the watershed management information system data of the Ministry of Environment and Forestry.
