The same authors have obtained reductions up to 50% of the HC emissions, using these pure biodiesel fuels.
Alam et al. [15] found a 60% reduction of HC with their biodiesel in a 6-cylinder diesel engine.
The experiments were started firstly with diesel fuel baseline data were recorded after the engine reached the operating temperature.
According to Lebedevas et. al. [23], RME has a reduction of HC emissions by 65% for all researched range of load.
RME has a reduction of HC emission up to 60.5%.

Existing research of panel data analysis shows that many empirical analyses are based on provincial panel data, and they ignore the differences between the cities.
The paper use the latest data to study the impact of FDI on the environment on the basis of the city panel data, and this paper recommend a lot of relevant policy advice.
Model specifications and data We make a Model to predict that the impact of foreign direct investment on environment.
It means that FDI decrease pollution reduction.
The model is estimated by the panel data of China's 130 cities’ industrial sulfur dioxide emission from 1991 to 2004.

The results of the study indicate that vibration acceleration value were not more than vibration control limits, vibration reduction and isolation reach the predetermined purpose.
If vibration reduction measures adopt improper, precious cultural relics is likely to suffer destructive impact.
Owing to the Chengdu metro vehicle parameters has not yet completely determined, the actual parameters are used for known vehicle data and Hong Kong metro airport line parameters are used for unknown data in Calculation.

Despite the improved interfacial morphology, a reduction of the peak mobility (from 40 to 24 cm2V-1s-1) was observed using the carbon capping layer.
While Haney et al. [11] observed that the use of the capping layer does not significantly affect the channel mobility in a wide PIA range (1200-1800°C), Naik et al. [12] recently reported a reduction of the mobility when the devices are processed with a capping layer.
As can be seen, a reduction of the Dit value close to the conduction band edge of a factor two was observed in the sample annealed without cap.
Fig.3 shows how our experimental data of mobility µFE and total trapped charge densities for the samples processed with and without cap perfectly follow this general trend.

Introduction
The basis for the industrial production of silicon carbide (SiC) is the carbo-thermic reduction of silicon dioxide.
This paper presents the results of calculation of the main parameters of the stationary process for the production of finely dispersed SiC according to the model for synthesizing silicon carbide in an EFB reactor and comparing experimental and calculated data.
The velocity of the beginning of fluidization and umf were determined according to the data of [9] and [10].
This confirms the possibility of transferring data on relative productivity from laboratory versions of the EFB reactor to industrial ones.

Reliable data of concentration vs. depth are obtained starting from about 0.2—0.3 µm from the surface down to about 2 µm.
Fig. 3 compares the Arrhenius plots of ep/T2 (where ep is the hole emission rate and T is the absolute temperature) obtained from carbon-implanted and not implanted samples with literature data [6].
Fig. 8 compares the Arrhenius plots of ep/T2 obtained from tungsten-contaminated wafers with literature data [7].
Vice versa no reduction at all of the tungsten concentration was obtained by carbon implantation in 10 ppb contaminated samples.
Our data suggest that this property is common to other impurities.

GTDiPS software [4] was used to correct the diagrams (elimination of data point duplication and reduction of the number of such points).
The data from F–CMOD diagrams were used as input data for the Double-K fracture model [5] which was used to determine the mechanical fracture parameters of the tested materials.
Elimination of the noise is ensured by setting the threshold level (400 mV), or by filtering during a post-analysis of the data.
Increasing amount of graphite filler caused a reduction of AE events detected until peak load.

OST differentiation was confirmed by Alizarin Red S (Sigma) and osteopontin (R&D Systems, Minneapolis, MN, USA) staining (data not shown).
Greater concentration of Col I were not used since they were detrimental to hematopoietic cell growth (data not shown).
In general, the proportion of MK (CD41+) and mature MK (CD41+CD42+) in Col I cultures tended to be lower than those observed in the control cultures (p>0.05, data not shown).
Col I coated surfaces were detrimental to platelet production, with a mean cumulative reduction of 70±10% (n=3) compared to control at day-14 (data not shown).
This reduction could be the results of the adherence of the cells to Col I, which has been previously linked to reduced cell proliferation [2, 5, 17].

In the first module, the beams, columns and slabs in frame structures are modeled by the finite element software SAP2000, in which the model data are read into ABAQUS depending on the program written in this paper.
In the second module, the position, heated faces and duration of members suffering fire can be specified according to the actual inspection data of members after fire.
In the pre-processing stage, a mass of original data should be inputted by the user that is to be read by calculation stage.
After the finite element calculation, plenty of data are produced, such as displacements, stresses and strains at the element nodes, etc.
