The infrared spectra of methylated cardanol (Fig. 4) exhibited reduction intensity of hydroxyl group (–OH) in the range of 3400 cm–1 and increased characteristic absorption of C–O–C linkage of the ether group in the range of 1081 cm–1 compared to cardanol.
GCMS Chromatogram of methyl cardanol by using DMC Fig. 7. 1H-NMR spectra of methylation of cardanol using DMC Analysis of the 1H-NMR spectral data of the cardanol methylation reaction product showed that there were 8 chemical shift regions.

Increasing the angle further to 4.5 deg generated a noticeable increase in forge force in addition to excessive flash on the retreating side and a decrease in weld quality approximately an 8% reduction in ultimate tensile strength and 45% decrease in elongation.
The temperature generated in the weld was recorded in a data logger with a sampling interval of 10 ms and accuracy of ±2°C for a calibrated K-type thermocouple.

The EBSD data were analysed using HKL Channel 5 software developed by Oxford Instruments, UK.
However, due to a reduction of the carbon content of the alloy under investigation and increase of the boron content cavity nucleation sites could be coarse grain boundary M3B2 boride instead of M23C6.

The Energy-Dispersive X-ray Spectroscopy (EDS) analysis data of amorphous SiO2 is shown in Fig. 4.
This results in also a reduction in the rubber matrix to strengthening the biosilica alloy.

These data indicate that the thylakoid membranes can lead to a series of changes at all levels of the plant (cellular, leaf and whole organism), and a delay in flowering and senescence[22].
The final developmental stage of chloroplasts – gerontoplasts – shows an increase in the number and diameter of plastoglobuli, a reduction of the thylakoid system, a loosening of the stacking of thylakoids and a swelling of intrathylakoid spaces[2].

In particular, when a lot of organic composite materials such as carbon fiber reinforced plastics (CFRP) are applied to aircraft components to decrease the weight reduction [3], titanium materials are also used because their thermal coefficient of expansion is similar to that of CFRP and titanium is not subject to damage by galvanic corrosion in contact with CFRP materials.
The above extruded bars of titanium composites were evaluated on an equivalent weight (i.e. areal density (AD)) basis and compared to conventionally rolled thin Ti-64 plate data [7].

Consequently, in the untreated fabric, the reduction of the cross-section (see Fig.1b), generally observed after the failure of materials subjected to uniaxial tensile tests, is more evident than in the treated fabric (Fig.1b).
Thus, the most relevant data from the tests are Pmax (i.e., the strength of the wall) and the corresponding deflection dp, whereas the residual stress of the post-cracking stage can be evidenced by AF and the coordinates [x1, y1] and [4 mm, y2].

The result is consistent with previous published study, which has indicated the thinnest area in the implant walls may cause a higher peak stress at the bone-implant interface due to the reduction of the contact area between the bone and the implant [19].

Like the MC model, the CA model is not perfect in simulating the grain growth process of a material, especially when experimental data for its identification are missing.
The role of the grain boundary curvature models in the case of highly deformed microstructures, e.g., after 90% rolling reduction, still needs to be confirmed and will be the subject of future research

Due to insufficient size of opening area, the fire has converted into oxygen-dominated fire, followed by rapid reduction of flame.
