Based on the obtained data, plaster made of lime hydrate, diatomite, and combination of water repellent agents can be recommended for renovation purposes.
Looking at the thermal properties data, the observed differences among investigated thermal parameters corresponded to the porosity and mechanical parameters values.
From the quantitative point of view, the thermal conductivity and specific heat capacity data are in the range typical for plasters of similar porosity.
The application of inner hydrophobisation and coating of boiled linseed oil resulted in significant decrease in the water absorption coefficient which means a significant reduction of liquid water transport in the plaster.
Except of a practical application of tested plasters, the obtained data can find use in computational modelling of coupled moisture and heat transport in building structures and components.

SolidWorks has rich function of parts entity reduction.
Before drawing the sketches, to choose the t sketch rendering datum, then with the toolbar of sketch rendering, add geometry relationship, change of entity references, isometric entity, the mirror, arrays, intelligent size, etc.
Firstly, on datum the sketch is draw.
Draft outline, termination of parts relation and reference datum plane can be the reference on other entity assembly bodies.

Subsequently, a geometric model of the sample’s surface was created using CAD software and compared with the scan data through ATOS Professional software.
Consequently, this leads to a reduction in loading frequency and a deterioration in the seal of the barrel-projectile system, ultimately resulting in a decrease in maximum pressure and the initial velocity of the projectile [7,8].
It is generally considered that if a worn barrel causes a reduction in initial velocity by 10% compared to the tabulated velocity (which can be verified by radar) or an eightfold increase in the product of probable deviations longitudinally and laterally Ug x Us, then such a barrel should be retired from further use [9].
This results in a reduction in the volume of the chromium layer.

Basic properties of aluminum material used for initial
input data of the finite element simulation and theoretical analysis were obtained from the true
stress-true strain curve of specimen which had bean extracted from the Al tube beam.
Introduction In recent automotive industry, reduction of the weight of the mechanical structures improves vehicle performance and fuel economy.
Basic properties of aluminum and composite materials used for initial input data of the finite element simulation and theoretical analysis are obtained from the true stress-true strain curves of specimens which had bean extracted from the aluminum tube beams and composite plates, respectively.
A true stress-true strain curve obtained by the above-stated method was used as initial input data for the finite element simulation and theoretical analysis, which is shown together with nominal stress-strain one in Fig. 3.
Table 2 summarizes data of flexural stiffness, the maximum moment and absorbed energy of hybrid tube beams obtained from modified theory and experiment.

Hard disk substrates play a key role in the data storage process of magnetic storage hard
disk drives (HDDs).
The disk arial recording density of hard disk drives will keep grow at 50% growth rate per year as the video-audio digital application system and data storage capacity requirements keep moving higher progressively [1].
Hard disk substrates play a key role in the data storage and data accessing process in hard disk drives (HDDs) [3].
The contributing factors to finish good disk defect performance are a function of polish removal capability and scratch reduction.
This is readily observed in the experimental data regarding surface finish and defect performance.

Microstructural hydrogen trapping behaviour in low- and intermediate temperature regions observed here was in coincidence with previous data obtained for RS materials using thermal desorption spectroscopy (TDS).
The information on H interactions with defects is often limited to high purity aluminum while most mechanical property data have been obtained for Al engineering alloys with transition alloying elements.
Obtained TDA results of the microstructural hydrogen trapping behaviour reveal new original data on H desorption kinetics at elevated temperatures in RS high purity Al and Al-Cr alloys.
Concerning unindexed small peak below peak 1a, its origin is not well understood due to a lack of experimental data for Al-Cr alloys and will not be discussed further in the present paper.
Note, instead of TDS data acquired by a quadrupole mass spectrometer in ultrahigh vacuum condition, TDA measurements are carried out in the atmosphere that contains oxygen.

Normality test of data distribution were evaluated using Minitab software and it was proven that all samples were in a very stable behaviour (p > 0.05).
The high speed impact data processing software generated the impact energy value in Joule [J] at maximum load applied.
From the collected data, the modulus of rupture (MOR) value or flexural strength of the specimen was determined in Pascal [Pa] unit.
Normality test for each properties data distributions were also being tested and all data were proven to be very stable (p>0.05).
They also pointed out that delamination was the most common failure mode and it may cause severe reduction in in-plane strength and stiffness, potentially leading to catastrophic failure of the whole structure.

The optimized data is consistent with some typical phenomena in hydroboration and ring-opening metathesis polymerization.
Semi-empirical method simplified the former with empirical parameters gained from experimental data to reduce the calculation time.
However, there exist deviations in the data of number 7 and 8 by AM1.
SS represents the sum of the squared deviations from the average, and the SS between groups reflects the differences in the data of each group.
