It is possible to draw a conclusion that despite a large amount of the moisture, which is formed in the course of combustion of wood, the fulfilled flue gases have high potential of moisture absorption and can be used as the drying agent as they have the temperature more than 180°С after an exit from the camera of thermal modification The results of a research have shown that increase in humidity of wood particles leaded to increase in formation of carbon dioxide and water vapor, to reduction of content of carbon monoxide and hydrogen.
Increase in formation of CO2 is connected with reduction of temperature in a zone of restoration and, as a result, with reduction in the rate of reactions of restoration that leads to reduction of CO and to increase in not decayed water vapor.
The obtained data shows that the intensification of process of gasification increases calorific ability of generating gas and exerts impact on its structure.
The obtained data allow us to draw a conclusion that thermal modification exerts direct impact on the change of density of wood: the higher the processing temperature, the more intensively decrease in density of material is.

Moreover, the data of the springback shapes, after unloading, of the sheet metal parts formed with the trial and corrected tool paths, used for iterative correction of tool path in the algorithm, are obtained with finite element model (FEM) simulation.
The use of this type of robot in the manufacturing process of parts by single point incremental forming is a great advantage, because is possible to determine, at any time during the process, some features, like: displacements, strains and thickness reduction compare with the case when we use a universal milling machine when all the data can be determined only at the end of the forming process.
The part to be measured by Aramis The system used to measure the strain and thickness reduction was Aramis by Gom optical system.
It should be noted that the Aramis computational system allows us the determination of displacements, strains and thickness reduction (which in reality is also a strain on thickness direction) in each acquired image.
In this table are presented the maximum values of major and minor strain, the maximum value of thickness reduction and also the maximum values of the springback value.

The paper [6] shows that in most cases, reduction in misses correlates with reduction in CPI.
Furthermore,we propose innovative another metric, that is the miss rate.Thus, we can use the information about reduction in miss rate to make cache partitioning decisions.If missa and missb are the number of misses that an application incurs when itreceives a and b ways respectively (a < b), the miss ratea and the miss rateb are the number of miss rate that an application incurs when it receives a and b ways respectively (a < b),then M a b of increasing the number of ways from a to b is: MRab of increasing the number of ways from a to b is: MRab =miss rate - miss rate a b (1) Structure of AMRM (1)To differentiate the access of different application,we add a register AID for every processor in the AMRM[7].When the processor accesses the miss address of the L1 Cache, it sends the data of the AID and the miss address to the bus together.The AID Core0 L1D AMRM0 LII CoreN L1D AMRMN LII …… Shared L2 Cache Figure1 position of Application-oriented Miss
The miss information in the counters correlates with the reduction in misses for a given multithread application when given a fixed number of ways.
Weighted Speedup The Weighted Speedup indicates reduction in execution time, where SingleIPCi is the IPC performance of an application when it use the shared L2 cache privately and IPCi is the IPC performance of an application when the shared cache is partitioned among the competing applications.
Last level cache(LLC) performance of data mining workloads on a CMP - a case study of parallel bioinformatics workloads[C].

Effect on morphology of Ni and Cd in composting sludge
1) Ni As can be seen from the data of the comparative test FA0 (Fig. 2), both EF and CBF with respect to the sludge after composting without FA were reduced, as the former decreased from 26.54% to 14.53%, the latter from 30.15% to 26.41%.
Results show that the passivation of EF in test FA35 was the best with the reduction up to 21.57% that even 9.56% lesser than the comparative test FA0.
On the whole, this transformation results in a reduction of easy migration state of Ni, and increased its stability in the sewage sludge.
Linear regression was used for evaluating the effect of the unstable state amount of heavy metals in sludge by using the scatter data of Ni and Cd unstable state contents after composting.

Therefore, the reduction in surface roughness, and hence the increase in surface glossiness, are mainly
dependent on the mechanical interactions between the diamond grits and granites, rather than
thermally induced chemical reactions.
This can be further supported by incorporating all the data into one plot.
Fig. 6 Measured grinding temperatures Fig. 7 Glossiness versus roughness for all data In the field of ceramics grinding, it is well known that the variation of surface roughness is directly related to the different grinding mechanisms [3,10].
In effect, it can be seen from Fig. 7 that there exists a critical value of roughness (about 0.2 µm), above which the glossiness does not change obviously with surface roughness, and below which a slight reduction in surface roughness may lead to a sharp increase in glossiness.

During extrusion, the force-stroke data was recorded using a data
acquisition system.
The hardness decreased to 91 VHN after 3 rd pass of route C ECAE due to the reduction in work hardening [11].
But the strength decreased after the third pass for both the processing routes A and C of ECAE, which may be due to strain softening leading to a reduction in work hardening [11].
Reduction in work hardening occurs due to the disruption and dissolution of the previously formed dislocation cell structure that can occur during the new deformation route.
Conventional extrusion carried out on solutionized specimens showed better strength than ECA extrusion of solutionized sample with little reduction in ductility.

In particular, the coefficients reported by the "Guide for the certification by the Regional Evaluation and Verification of public investment Units" [2], valid for the whole country, have been used and calculated primarily using national accounts data (Table 1).
The valuation of the lower external costs is performed using the information and the data reported in "Handbook on estimation of external costs in the transport sector" [5, 6].
It is also assumed that the benefit connected to the reduction of gas emissions from cars as well as the noise pollution is negatively offset by the gaseous emissions and the noise of the train service (the trains are fuelled by diesel).
By using the average cost of fuel for a car (0.1388€/km) and that of its maintenance, including, car tax, insurance, mortgage interest (0.1685€/km) [11], assuming also a reduction in the use of the vehicle of 3 km per passenger these items could be calculated: - Fuel savings by passengers 3*0.1388*2.620.000*72%= 785.496,96€/year - Saving maintenance and taxes related to private vehicle for passengers 953.575,2 €/year Considering a ticket price of 0.5 €/running and therefore, a total cost for the use of the metropolitan service equal to 943.200 € / year, the reduction of the costs of mobility is equal to: RMob=RCarb+RManut-CBigl= 795.872,16 €/year
So with a reduction equal to 1/3 of the number of passengers estimated (from 2,800,000 to 928,135), the project is still self-sustaining.

The concrete shear resistance seems to change little and the shear capacity can be calculated by just taking into consideration the reduction in stirrup shear resistance.
Test data from published literature [4], [5], [12] were also introduced in Fig. 10.
That is to say, if the maximum sectional area loss of the stirrups due to corrosion is below 45% (for the test data in this study, the value is 35%), the influence of stirrup corrosion on Vc can be ignored, and the shear capacity can be predict accurately by just taking into account the reduction of Vs caused by maximum sectional area loss of the corroded stirrups.
The shear capacity can be evaluated simply by allowing for the reduction of Vs due to the sectional area loss of the stirrups.

The data suggests that the process
reported has the ability to mass-produce carbon encapsulated ferromagnetic nanoparticles with
desired particle size distribution, and hence with controlled size-dependent magnetic properties.
With these potential benefits, carbon encapsulated ferromagnetic nanoparticles have received considerable attention in recent years as small magnetic clusters in high density magnetic data storage, xerography, and magnetic resonance imaging [2].
The XRD data was measured using the Phillips X-Pert high-resolution horizontal diffractometer using the Cu Kα radiation (1.5405 oA ) directly from powder samples.
Initially, it was thought that the reduction in Ni content played an important role in the reduction of magnetisation values.
