The reduction of tensile strength values in biocomposites is typical due to poor interfacial bonding between the hydrophilic bio-based materials and hydrophobic PLA.
The statistical significance between the reference and filament sample data was tested with Daniel’s XL Toolbox Excel software.
The data was analyzed by using the one-way ANOVA Bonferroni-Holm post hoc testing algorithm.

Shi. et al. studied the reaction between Mg and B with the DTA method that the presence of MgB2 phase becomes effective in the samples at a sintered temperature above 700°C.[21] The XRD data of samples 1 & 5 also support the SEM morphology.
Comparing with the SEM and XRD data of samples 2 & 6, it is clear that the crystal structure of MgB2 of sample 6 is better than sample 2.
Moreover, the reduction of the Mg element is also causing a decrease in the value of TC,onset, and TC,zero.
We can also confirm the proof of unreacted Mg from XRD data.

According to data collected by the International Renewable Energy Agency (IRENA) on some 17,000 projects in 2019, since 2010, the cost of energy has fallen by 82% for solar photovoltaics, by 47% for concentrated solar power (CSP), by 39% for onshore wind, and by 29 % for offshore wind.
In determining the current work, more recent data (2021-2022) will be more useful.
To evaluate the overall updated cost of the cubic meter of pumped water, it is necessary to have certain data, namely [28]: · The lifetime of each component, · The initial cost or investment, · Annual maintenance costs related to the photovoltaic system, · The costs of replacing the different subsystems.
Recall that these projects will ensure the reduction of Algeria's food dependence by replacing the growing demand for fossil energy by exploiting alternative and renewable resources that are likely to spare it from the vagaries of fluctuations in the world oil market.

The obtained data showed that, depending on the process temperature, one type of S-shaped rheometric curve is observed for all rubber mixes, when, over time, the values of the torque increase with the exit to the vulcanization plateau.
The presented data demonstrate that the adding of Phytonorman products into the mix leads to a decrease in the minimum (S'min) torque, the value of the torque increment (ΔS’), the rate of the vulcanization process (Rv); an scorch time increase (tS1, tS2, tC(10)), the optimal vulcanization time(tC (90)).
According to the effect on the degree of reduction in strength indicators, the considered Phytonorman products can be arranged as follows: Phytonorman 212 < Phytonorman 213.
At the same time, as the shrinkage data, parameters k and a demonstrate that the greatest positive effect on the rubber mix relaxation properties is observed when adding 7 phr of oils.

Based on the limited manufacturing facilities for injecting the powder material in 5 axes, the demonstrator has a 1:10 scale reduction with regard to the real turbine mounting lugs.
As far as the material properties are concerned, the data recollected from the bibliography have been implemented to quantify the character of each manufacturing process.
Regarding the forged properties of Inconel 718, those provided by the Ansys data store are employed except for the elasticity modulus, which is extracted from the AMS 5662M standard for aeronautical Inconel 718 [19].

The specimens were got from the same plate, choosing smooth place from the surface polishing processing sample plate before treatment, taking three data points, drawing a Φ20mm circle with a compass, and then marking to distinguish between data points.
Using NF333 color measurement spectrophotometer to measure color parameters (L*, a*, b*) and total color difference (ΔE*) at data points, and then recorded them.
The color saturation decreased and the reductions in Δb * and ΔC * after 12h, 16h steaming are similar to control.

The thermocouples were connected to a data acquisition system (National Instruments SCXI-1000) to record the temperature at a sampling frequency of 20 Hz.
Each data point represents the volume fraction in an area 250 ´ 188 µm2 and it was obtained from micrographs taken from casting edge to casting centre.
On the other hand, vibrated castings exhibit shortening and a reduction in size of their eutectic Si particles, which also assume a flake-like morphology, even if a few islands of unmodified eutectic cells are still present.

In the case of blast furnace slag, it is necessary to eliminate the decomposition of silicates, which in principle is a modifying transformation of b-C2S to g-C2S, accompanied by a change of volume of the end product amounting to ca. 10% and by a reduction of bulk density.
Owing to the lack of an adequate quantity of exact data that would make it possible to ascertain the potential amounts of deformation caused by instability of the mineral phases present in steelworks waste and the potential swelling pressures, experimental testing was done at the laboratories of ARCADIS Geotechnika Corp.
A more substantial series of tests will have to be run for the data learned to be valid.
As evidenced by experimental data on the granulometric composition of steelworks waste (see above), the share of the fraction under 10 mm exceeds 50% in most cases.

Recent trends in time-based competition and inventory reduction requires products to be completed in shorter time and with more reliable delivery dates.
The proposed models are solved using data for benchmark instances from the literature.
Part Data Ten different part types are considered for processing in the FMS.
Part sequencing rules based on the status of the system in addition to part data can be analysed in future research.

Most of the cultivated plants are sensitive to salt stress, and NaCl salinity which results in ionic disturbance, osmotic and toxic effects [2] usually causes a great reduction in vegetative growth, the rate of photosynthesis [3] and also water availability and imbalance in nutrient uptake by plants [4].
Data were subjected to a one-way ANOVA using the SAS™ software (SAS Institute Inc 1989) to test for the main effect of NaCl addition (across all P levels) and for the effects of H2PO4--P addition within each level of NaCl.
Interestingly, water contents of hybrid pennisetum both in shoots and in roots were not significantly different regardless of P level or NaCl level (data not shown).
Our data also showed that under salinity stomatal conductance (Fig. 3C)and transportation rate (Fig. 3B) and enhanced intercellular CO2 (Fig. 3D) of hybrid pennisetum were markedly reduced, however, they were not significantly different in elevated P supply treatments, suggesting that stomatal limitation to photosynthesis did play a major regulatory role in CO2 assimilation in hybrid pennisetum, but that factors other than the CO2 supply are crucial for photosynthetic restriction under P deficiency conditions in hybrid pennisetum.
