It should be noted that the results are dependent on the approximation to semi-spherical wear scars of the raw data.
It has been pointed out that as sliding distance increase, the area of the contact will change (and generally increase) thus resulting in a possible reduction of the load per abrasive particle with increasing sliding distance.
Results and discussion Sliding distance It is suggested that the sliding distance reduction leads to the wear rate decrease due to the decrease of nominal contact pressure at the specimen surface [12].

The studied alloy were wires produced from the cast AH140 (Trefimetaux), their reference data are: Ms = 255 K; Mf = 226 K; As = 253 K; Af = 275 K.
Reduction of the cycling amplitude to near or under 200 MPa increases the fracture life.
The use of SMA dampers (as shown in Fig. 2 Right) at this reduced excitation amplitude produces a drastic reduction of the oscillation amplitudes in the portico beam.

The reduction of color in HA photodegradation with HA initial concentration of 10 mg/l was treated by a photocatalytic reactor filled with 60 g of glass fibers coated with the catalytic films.
From Fig. 5a), it can be seen that the Sn 3d5/2–binding energy (485.1 eV) of the Sn–TiO2-x is less than the reference data of Sn 3d5/2–binding energy (486.6 eV) reported [7].

These sub-modules are connected by the use of MATLAB, also the inputs (e.g. initial data or parameters) and outputs (e.g. plots and tables) are managed by this way.
Therefore, the simulation shows that the smaller furnaces reach their maximum storage level at several times which causes an interruption of melting production and finally means a reduction of melting capacity.
In consequence of the absolute control scheme, the storage level of the bigger furnaces is reduced on the level of the smaller furnaces which at least causes a reduction of storage capacity.

Crushing and spalling phenomena
About the phenomenon of expulsion of stone portions which constitute the bearing element, it involves a progressive reduction of the resistant cross-section (fig. 5.a) with subsequent detachment of ashlars from the masonry element (fig. 5. b).
Figure 5: a) Reduction of cross-section; b) Expulsion of stone elements; c) Presence of different elements with respect the original material As well known, pulverization is another phenomenon which can amplify the effects of crushing.
In this case, Eb and Ef were assumed equal to 40 and 71 GPa respectively, as indicated by the data sheets provided by the manufacturer.

The reduction was continued while stirring at 50 oC for 1 h.
By analysing the XRD and TEM data, it is possible to conclude that Au crystallite size (dkr) and the average size of Au nanoparticles calculated by TEM are approximately equal.

Several attempts have been made by researchers in order to improve the conductivity of LiNiPO4, for instance, by introduction of carbon coating [2] and particle size reduction [11].
The data obtained were corrected with sample geometry (area/thickness) before analysis.
It requires further enhance by surface coating with carbon and reduction of particle size.

Other thermodynamic and thermokinetic data calculated from the adiabatic rise of the temperature are listed in Tab. 3-5.
The obtained data showed that thermal modification of wood slightly increases the critical density of heat flux.
The collected data will find important application as input data for fire modeling, investigation of fire causes and accidents, as well as during solving of fire safety of buildings on the basis of performance design.

Comparing to the similar performance sets in home area, this set has a more than 35% reduction on weight, which made it very practice to be applied in small reservoirs in remote regions with no road to get on dams or even with only walkways.
The design of the support structure of blade wheel axis is changed from traditional jib arm to simple supported beam, which gets the profit below: as the stress condition of wheel axis is changed, the running stability is improved significantly, the vibration and noise are reduced, the problem of overheat of bearings in jib arm supporting point which has a negative influence on continues running are solved fundamentally, and the weight of this part gets a reduction of more than 50%.
