Reduction of process steps can be achieved by connecting the face layers and core in-situ via in mold assembly process using foam injection molding (FIM).
To obtain statistical valid data at least 5000 individual fibers were measured [10, 11] and scanned.

Necessity for reduction of greenhouse gases emissions, the growing demand for improvement of biorefinery technologies and the development of new biorefining concepts, oblige us as a society, mainly scientists, to develop novel biorefinery approaches.
The legislative ideas and policy actions included in the Fit for 55 package are as follows: 1) the EU's emissions trading system, 2) member states' emission reduction targets, 3) emissions and removals from land use, land use change, and forestry, 4) renewable energy, 5) energy efficiency, 6) alternative fuels infrastructure, 7) CO2 emission standards for cars and vans, 8) energy taxation, and 9) the carbon border, 10) sustainable aviation fuels, 11) greener fuels in shipping, and 12) social climate fund [2].
All the above-mentioned growing demand for the reduction of greenhouse gases and the improvement of biorefining technologies and the development of new methods oblige us as a society, mainly scientists, to develop sustainable lignocellulose (LC) processing technologies.
Three parallel tests were run for each sample, and the average of the data is displayed with a relative standard deviation (RSD) for all experiments that was less than 5%.

Moreover, the fatigue limit theory was used to obtain the best relative clearance, which can provide theoretical data to the bearing structure optimization.
The relationship between relative clearance and temperature firstly displays the tendency of reduction and then the trend of increment.

The experiments have shown that sufficient data have been obtained to give confidence in the reinforcing mechanism of stay in place construction formwork, and future work need only be focused on formwork design and standardization.
Regarding the structural behavior, it was found that the reinforced concrete Coffor walls are more ductile compared to the conventional reinforced concrete walls while a reduction in their capacity was observed.

Without the half select condition, the proposed 10T cell allows efficient bit-interleaving to provide soft error rate protection and the dynamic power is also decreased significantly due to the reduction in the number of bitlines discharged and charged during the read and write operation.
When column-based write signal is activated, the data will be written into the selected cell.
Because we do not need to consider pull-up ratio and the read margin during the write operation, the two pass gates (M7 and M8) and the portion for storing data can adopt the minimum size design.

With increasing number of ECAP passes and cold rolling reductions, the initial coarse grained structure in the as-received material was transformed gradually into an ultrafine grained microstructure with an average grain size of 0.2~0.3 µm.
When the experimental data point of hardness deviation is plotted again with the gradient of hardness obtained in figure upon accumulated strain, their tendency shows very well correspondence, as is shown in figure 6 (b).
