During the experiments, the variation in ambient temperature and relative humidity was recorded using a tempnote TH32 reusable temperature and humidity data logger at a sampling rate of 10s.
Ambient temperature and relative humidity are nuisance factors that affect the drying in a non-uniform way, which might result in erratic data distribution in some cases.
Furthermore, for (), they observed a substantial reduction in the drying rate.

The consequence of the detrimental effect of residual stresses (usually tensile) is the formation of cracks, the reduction of fatigue life, lower brittle rupture resistance, the occurrence of stress corrosion and the like.
By monitoring these parameters and comparing them with the data of the same but stress-free sample, the magnitude of residual stresses occurring in turning can be determined.
The methodical part of the experiment consists of: • machining of material, • symmetrical cyclic loading of material by pushing-pulling, • the comparison of the lifetime curve of the processed sample with data of samples free of residual stresses.

Arcam AB (Sweden) developed the technology and machines for the production of patient-specific implants using data derived from computer tomography.
The data is used to create an exact CAD model of the desired implant.
Machining of sintered titanium preforms leads to increased tool wear and to reduction of open porosity.

The localization of these peaks was found in good correlation with the literature data [10].
There was about 30 % reduction of the Si-H peak on the H passivated samples as depicted in Fig. 2(a).
Table 4 shows the process data and the thickness (in Angstrom) of the nitridized layers with the N-content, (in %) measured by XPS.

A seeding efficiency of over 90% was found (data not shown).
The result of the ALP data normalized for DNA is presented in Fig 4B.
ALP expression which was used as a marker of early osteogenesis of osteoblasts and control showed significant reduction of cells differentiation compared to Rainbow B, CPS and CPS+Sr.

The effect of cutting and cutting fluid application parameters on cutting temperature and surface roughness were analysed in hard turning of OHNS steel of 45 HRC, the significant reduction in cutting temperature and surface roughness were observed [18].
This indicated the excellent adequacy of the data set to the model.
The residuals falls on a straight line implying that the errors are distributed normally and confirms the normal distribution of data..

It has been seen that in the aluminum modified materials, aluminum content results in a reduction of the surface area and an increase of pore volume.
Specific surface area and pore volume of the different samples measured from N2 adsorption isotherms data.
Figure 8 contains experimental data relating the conversion of α-pinene versus the reaction time, employing the Al-MCM-41-5 and Ga-MCM- 5 catalysts at 373 K.

The reduction of intensity is mainly caused by contrast matching between the silicate framework and organic moieties which are located inside the channels of SBA-15 [23].
Both the First-order model and the Second-order model can fit adsorption kinetics data.
The adsorption data are fitted well with the First-order model and Second-order model.

The data is got by using origin Pro 7.5 software analysis, and it can get the maximum absorption peak wavelengthλ max.
The three characteristic peaks solution absorbance scan curve of MRλ max1=362nm,λ max2=426.5nm are located, λmax3=585nm, then the comparison, in the water after the addition of HBS-1, methyl red three in water absorption maxima peak blue shift occurred in high frequency, low wavelength (lambda max<500nm) wavelength value reduction 4 ~ 6nm, while in the low frequency and high wavelength values (λ max>500nm) wavelength value trend is very obvious, the reduced 30nm.
The absorbance scan curve C precipitate is lower than that of D curve, data indicating the changes of absorption solution of the maximum position, three the maximum absorption peak position respectively intoλmax1=364.5nm, λmax2=427.5nm, λmax3=583.5nm, these three figures and aqueous solution of MR three characteristic peaks of absorbance values were almost the same (lambdaλmax1=362nm, λ max2=426.5nm, λmax3=585nm).

Some examples of important monumental buildings in Rome and Naples have structure of chestnut with irregular cross section, for which it is difficult to come to reliable data on mechanical properties in the diagnostic phase.
The data analysis started with the calculation of Pearson correlation coefficients, to check the influence of the visual parameters over the mechanical properties of the timber.
Furthermore, as concern the bending strength, currently no adjustment for moisture content is recommended by the standardization, but further tests are going on to verify that no significant reduction on strength properties exists from green to dry timber conditions.
