Such a reduction of the task dimension by one rank makes it easier to prepare input data.
Applying larger positive values of the addendum modification coefficient for a toothed flexspline rim caused reduction of stresses at the tooth space bottom (Figure 4). 2.
Decreasing the value of the gear tool head curve radius causes shortening of the tooth root transition curve and reduction of the tooth thickness at the base, which leads to an increase in the stress values. 3.

This technique leads to the most drastic particle-size and crystallite-size reduction [8,11], which significantly improves the hydrogen sorption kinetics due to the increased density of lattice defects and grain boundaries [12-15].
As seen, severe plastic deformation during the HPT process results in a crystallite size reduction, reaching a minimum value of D~120 nm after N=2 revolutions, in line with other observations on hcp and fcc metals [17].
In addition, data for other SPD materials are also presented.
The modified Williamson-Hall analysis of the X-ray Bragg-peaks revealed that the HPT process results in a crystallite size reduction, reaching a minimum value of D~120 nm after N=2 whole turns.

It is well known that the peak separation () between the oxidation peak and reduction peak can be used as a criterion for judging the reversibility of a redox process, and if it is a reversible process, the following equation holds [19]:
2.3RT/nF (2)
where R, T, n, F, are gas constant, absolute temperature, the number of electrons and Faraday constant, respectively.
It can be seen from Fig.1 (b) that there is a good linear relation between ip and 1/2 for the peak A in Fig 1(a), which indicates that the cathodic reduction process is controlled by ion diffusion.
This means that the reactant concentration on the electrode surface can be maintained, which further confirms that reduction process is controlled by ion diffusion.
All the peaks of the two samples except the peaks for ITO can be indexed to the reported data of Bi2Te2.5Se0.5 (JCPDS card 51-0643) only the peaks for sample S2 slightly shift to higher angles.

A further
reduction of the crystal size (i.e. a further increase of the volume fraction of boundary cores) seems
not possible as it increases the total energy stored in NcMs to energies above the energy of a glass
with the same chemical composition so that the NcMs may reduce their free energy by relaxing into
a glassy structure as was observed e.g. when the crystal diameter of nanocrystalline Si was reduced
below about 3.5nm
This density reduction is about three orders of magnitude larger than the maximum density reduction achievable in many crystals by a supersaturation of vacancies.
Moreover, by combining the X-ray measurements with dilatometric data ("Simmons -Balluffi measurements"), the free volume was found to be dispersed randomly through out the volume (delocalized) and it was not present in the form of vacant atomic sites as e.g. in crystals containing vacancies.

When the rock of new formation is exposed to exogenous
agents, it appears expanded in a pattern of cracks due to weight's reduction and to a physical and
chemical change of its structure.
While the second ones cause chemical processes of alteration, that include oxidation, reduction, solution, carbonation, corrosion, hydrolyse and hydration, operating on rock's mineralogical equilibrium and determining its decomposition.
The recent optimization of data acquisition allows to attain precise information on the global conformation of earth-like clusters situated under these geological sites.
The reduction system of walls/towers' fuori piombo will be carried out in sequential way; that is to say that firstly the less inclined wall will be straightened, then the adjacent one and finally the remaining part.

KISTLER 7061B-type pressure sensors were used for measuring cylinder pressure and a set of Yokogawa DL750 Dynamic analyzer was used for data acquisition.

With the BMEP rose to 0.605MPa, the difference of maximum cylinder pressure became inconspicuous in the wake of the reduction in fuel supply advance angle, the Maximum Cylinder Pressure reduced and its position moved away from TDC, the maximum cylinder pressure declined from 8.85 to 8.23MPa and its occurrence moment was later 2°CA than that of diesel.
No matter how working condition, the Maximum Cylinder Pressure reduced and its position moved away from TDC with the reduction in fuel supply advance angle.
The reduction of maximum combustion temperature greatly inhibits the generation of NOx emissions, this effects have been verified in earlier emissions testing directly.

NaOCl can bring the potentials of the specimens up and provide oxygen for reduction reaction in neutral and high pH conditions.
For low pH condition, hydrogen reduction reaction takes place.
Our preliminary results were not staightforward, and there were missing data to be retested.
This behavior can be explained that the reduction of pH at crevice and the pH6 level was an optimal potential difference for corrosion, where as the pH4 results in smaller potential difference, and the pH8 was too much potential difference under a given corrosion duration.

Determination of activity of mitochondrial and cytoplasmic dehydrogenases in living cells was performed using the MTT assay, which is based on the reduction of a colorless tetrazolium salt

The circadian transmittance τc describes the factor of reduction of the circadian effect of light transmitted through glazing.
Data obtained from measurements of the samples are presented below in graphs where x axis represents the wavelength and y axis represents the relative spectral transmittance or reflectance.
A significant reduction in the amount of circadian transmittance when compared to light transmittance can be seen for the yellow sample.
This reduction of blue light income can lead to health problems and should be considered in the designing process [11, 23].
