According the data of XRD, the average grain size of ZnO is 15.1 nm consistent with the result observed by TEM (16.3 nm).
The possible reason is that too much MB darkened the solution leading to the reduction of light irradiation to the solution.

Positron Annihilation Lifetime Data Analysis For each lifetime spectrum 106 or more coincidence counts has been recorded with 8000:1 random ratio.
Except data taken for 50K and 20K, others spectra were fitted with Lorentzian profiles using Recoil software [47].
Open symbols are experimental data.
Lines from two sub-lattices and total contribution are fitted data.
Note that the change of temperature variation of ISA and ISB below 200K is occurred in the temperature range where M(T) data suggest short range ferrimagnetic ordering of the sample and resistivity data are magnetic field dependent.

A 3D chiral metallosalen-based MOF [Cd2(Cu(salen))(DMF)3]·DMF·3H2O with an 1D open channel was synthesized then transferred to [Cd2(Cu(salen))(DMF)3]·DMF·3H2O (3) upon post-reduction by NaBH4.
The synthesized RuIII/salen MOFs underwent the actuation of a MOF catalyst through a reversible single-crystal to single crystal reduction process.
The reduction of the RuII CMOFs had high active for the asymmetric cyclopropanation of substituted alkenes (Scheme 7) with high dr and ee values.
Besides, nearly all the datas reported currently are based on short-term, small scale tests.

The measured input/output data is the major source of data for understanding system degradation behavior.
Maintenance data gathered by many organizations under different environmental and operating conditions is often used as inputs to the PoF models for estimation of the degradation in a systems[1], while maintenance data may contain data for unscheduled removals, component replacements, in process failures and rework and it may also contain data for different intermittent failures.
ML incorporates statistical and probability theory in addition to data preprocessing, dimensionality reduction by compression and transformations, feature extraction, and cleaning.
For a legacy product, the training data can be obtained from the historical data of the monitored product.
The training data can also be selected from the initial healthy state of the monitored product itself if the historical data is unavailable.

Then, the data were measured at a temperature of (290 ± 7) K for 6 hours.
At this temperature, the data were measured for 6 hours.
Like the SRD data [6,7], there was no change in the appearance of the ND data when the experiment was repeated.
Comparison of the fits in Figure 3 where neutron and synchrotron data are both plotted with the same x-axis (d-spacing) shows that the peak intensities are quite different in the two data sets.
Trial refinements initially using only the synchrotron data sometimes found a false minimum with somewhat worse goodnessof-fit indices, however, when both data sets were used the same minimum was always recovered.

The obtained data of experimental researches allowed to develop technology of removal of phosphorus compounds simultaneously with biological sewage treatment.
When using immobilized microflora, the reduction of phosphate concentration is somewhat higher than in the unit with free-floating microflora.
Of course, the anaerobic conditions created in the middle of the carrier to some extent improve the absorption of phosphates by microorganisms, but the ratio of aerobic zone and anaerobic zone in immobilized microflora is such that the aerobic zone is much larger than the anaerobic zone, where according to reference data the transition of phosphates back into aqueous solution takes place.
Experimental data show that the level of phosphate removal under anaerobic conditions depends primarily on the concentration of activated sludge in contact with the phosphate solution (with wastewater).
At a concentration of activated sludge of 3.5 g/dm³, the reduction of phosphates is vigorous, and after 8 hours of contact, the phosphate content is 0.18 mg/dm³.

The result of the data was then converted to a void fraction form.
The void fraction of this study is used to improve the prediction of pressure reduction.
Void fraction data is obtained by analyzing images captured using high-speed cameras and processed by image processing.
Measuring instruments used in this study include Mpx, data acquisition, temperature indicator, pressure indicator, airflow meter, water flow meter, and thermocouple.
Time Average results obtained from data processing using Matlab application are then reprocessed using Ms.

The calculated joint force value and tested data were listed in table 1.
It proves that the calculated shear force fluctuates near the tested data.
Table 1 shows that the calculated joint bending capacity is larger than the tested data.

To put it in another way, it is to determine the width of the flange with the inequality , in which stands for the reduction factor of the joint’s vertical bearing capacity and its value can be 0.9.

The instrument provided real-time data on the torque generated during vulcanization, enabling the determination of critical parameters such as scorch time, optimum cure time, and maximum torque.

This reduction in tensile strength is likely due to the poor compatibility of the EG with the rubber matrix.
a) b) c) Fig. 1 SEM images of the sample containing containing EG50 (a), EG100 (b) and EG200 (c) The data presented in table 2 and Fig. 2 underscore the importance of EG in rubber formulations.
The data indicate that samples containing EG and APP had lower T-5wt%, T-20wt%, and Tmax values compared to samples without these additives.

Design of experiment, DoE is an efficient method for data analysis in statistics, and for obtaining valid results [22].
The measurements are repeated three times and the averaged Ra was taken for the analysis to obtain the statistically significant data for each test.
It can be used for a variety of purposes such as analyzing experimental, ordinal, or categorical data [3].
Recently, based on reviewed by [19], CS is widely used in application such as engineering, pattern recognition, job scheduling, networking, Object-Oriented software (software testing) and data fusion in wireless sensor networks.
