Using a profile projector and graphical data processing and analysis software, the area of the fracture surface of the specimen was meansured, which allowed to correlate a crack size with a corresponding value of potential drop and the calibration curve.
This reduction in sensitivity eventually incorporated errors and even rendered crack propagation imperceptible.

From the XRD data, it could be observed that sharper crystalline peak and higher crystallinity index (CrI) present within heat-treated samples which corresponded to higher crystalline structure of cellulose I.
Our research finding was found in corraborated with work done by Man and his co-workers in which trend of increase in crystallinity index and reduction in crystalline size were observed in NCC [6].

However, the database is structured data.
Even if the data is changed slightly, it does not affect the effective use of data, including the use of semantics [7].
Select 65,000 tuples as a test data.
It can ensure the smaller distortion of data, so the watermark embedding does not affect the use of the data.
Rights protection for relational data[J].

Carbon Capture and Storage (CCUS) is the technological process of separating carbon dioxide from emission sources and then directly utilising or storing it to achieve carbon dioxide emission reduction.
TEM data confirmed that the type of carbon source and urea modification had a sizable impact on the formation of pore structure.
This is consistent with the material N2 adsorption-desorption data.
Fig. 10 CO2 adsorption data and linear relationship between (a) microporous volume, (b) microporous specific surface area and (c) nitrogen content The LCC-0.5N material with the highest CO2 adsorption value was selected to investigate the impact of different CO2 flow rates on the CO2 adsorption capacity of urea-modified porous carbon materials, and the results are shown in Figure 11.
Large scale production of biomass-derived N-doped porous carbon spheres for oxygen reduction and supercapacitors[J].

Low-velocity impact damage on sandwich plates introduced significant
reductions in tensile, compressive, shear, and bending strengths [2,8,9].
To validate the presented finite element model for the sandwich structures under transverse impact, a one-core sandwich structure with a core with thickness of 15mm is first simulated, and the calculated contact force is compared with the experimental data obtained by Chee [18] as shown in Fig. 2.
Compared to the experimental data the calculated contact force shows a little bit higher peak value and shorter duration.
That means that total stored energy of the individual configuration of the sandwich structures is almost same under same impact energy. 0.000 0.002 0.004 0.006 0.008 Time (sec) 0.0 0.2 0.4 0.6 0.8 1.0 Contact Force (KN) HC=15.0mm Experi. data [18] LS-Dyna FEM 0.000 0.002 0.004 0.006 0.008 0.010 Time (sec) -5E+3 0 5E+3 1E+4 1.5E+4 2E+4 Contact Force (N) Impact Energy: 43.56J HC=25.0mm HC1=12.0mm HC1=9.0mm HC1=6.0mm HC1=3.0mm Fig. 2 Calculated contact force Fig.3 Contact forces of the targets compared with experimental data [18] under impact energy of 43.56J 3.2 Local Displacement of the Core In order to evaluate deformation of the core element the displacement of the Node: B, as shown in Fig. 1, is collected and shown in Fig. 4.
It can be seen from Fig. 5 that with increase of the impact energy, the less the values of HC1, which is the space between the impacted face sheet and the internal sheet defined early, the more efficient of the internal sheet for reduction of the displacement of the node.

This data shows that the highest H2SO4 concentration proved to have generated an optimum sulfate impregnation condition.
The TGA curve shows a mass reduction over a temperature range of 50-200 °C.
The NiMo-SZ catalyst had a smaller mass reduction than the SZ catalyst, meaning NiMo-SZ had better thermal stability than SZ.
This data was evidenced by the greater conversion value of the NiMo-SZ liquid product than ZrO2 and SZ.
Product composition distributions of the catalysts Selectivity test for liquid products based on GC-MS data shown in Table 7.

Conventional
superplastic materials usually have small grain sizes in the range of ~2-5 µm so that a reduction in
grain size to the submicrometer level by ECAP provides an excellent opportunity for achieving high
strain rate superplasticity in conventional alloys [7].
The data in Table 1 show that the Al alloys exhibiting superplasticity have two common characteristics: firstly, the grain sizes are within the submicrometer range after processing by ECAP; secondly, the alloys usually contain alloying elements in their chemical compositions that lead to the formation of precipitations or second-phase particles.
The strain rate was plotted against stress logarithmically using data collected from experiments both under creep conditions of constant stress at the lower strain rates and using an Instron machine operating at a constant rate of cross-head displacement at the faster strain rates.
It is apparent the prediction is consistent with the experimental data in the superplastic regime to within a factor of about 2 and it is reasonably concluded that flow occurs in this material by the same superplastic mechanism as in conventional materials with larger grain sizes.
There is a good consistency between experimental superplastic data for Al alloys processed by ECAP and predictions using a relationship developed earlier for conventional superplastic materials. 3.
