The electronic circuits have significant reduction in consumption of electricity and are isolated from resin, reducing the risk of explosion due to leakage of unwanted gas.
As the dimensions need not be reduced for this application, a special reel for the processor could be developed; 3 o ) installation of the electrodes - The igniter can be fitted with the electrodes, being installed near the point of exit of the gas, this allows for length reduction of the conductors.
Based on data that can be collected by a net of biogas burning and registers net, installed in small sewage treatment stations.

The results show that the incorporation of CPR into the ceramic mass formulations has little effect on mechanical properties at temperature of 850 °C, characterized by a slight reduction of this property with an increase in CPR content.
On the other hand, at temperature of 1050 °C, the clay + CPR system shows a reduction in mechanical properties with an increase in CPR content.
Only through EDS data it's possible to identify the original regions richest in CPR and therefore richest in sulfur and calcium, and the regions corresponding to the clay matrix (region A and B, respectively) in the micrograph of Fig. 6(a).

The reduction in density for the higher MgO materials even with increasing sintering temperature shows that the powder bed is less effective in preventing weight loss by volatilisation.
The weight losses shown in Table 1 can therefore be attributed to carbothermal reduction of the oxide-rich surface layer. 30 minutes 1,6 2 2,4 2,8 3,2 1450 1500 1550 1600 1650 1700 1750 Temperatures ( oC) Density (gcm -3 ) M2 M3 M5 M10 Fig. 1.
The data collected at different heat-treatment temperatures confirm that very little gaseous loss occurs below ~1400 o C, and for effective removal, the highest possible temperatures below the Si3N4 → SiC conversion temperature are the optimum for the process.

In multi-scale image analysis, a hierarchical data structure is necessary to describe images with different spatial resolutions from low to high[5].
In the dynamic reduction process, the number of segmented image objects on different scales may change.
As the above, the multi-scale segmentation is actual reduction process of TM.

Table 2 Durability data of different concretes No.
When W/B continues to increase after 0.4, the magnitude of R-value reduction slows down.
Though the W/B (0.4) of air-entrained SF concrete is higher than that of non-air-entrained SF concrete (W/B=0.35) that results in R-value reduction to some degree; for non-air-entrained SF concrete, when the mixing amount of SF increases from 0% to 5%, the R-value increases by 52.1%, indicating that the mixing of SF is good (a) (b) (c) (d) Fig.1.

In the course of using the construction work, due to a number of factors there is an occurrence of defects, degradation processes, a decrease or even a loss of functionality and a gradual reduction of technical lifetime, eventually leading to the demise of the construction as a result of reaching a certain limit state.
The aim of this examination is to collect the up-to-date detailed data on the construction work.
In the period of using the construction works, there may, for various reasons, occur damages or malfunctions, i.e. a reduction or a complete loss of functioning of parts of constructions or even the whole constructions.

The AA 7075-T651 base material exhibits almost no strain rate sensitivity up to a strain rate of about 103/s, which is quite consistent with the compression test data on AA 7075-T6 by Holt et al. [9].
Note that there is a 15 to 28% reduction in the compressive flow stress of the base material, independent of strain rates.
The reason for the reduction in the flow stress level is that the FS welding process redissolves the strengthening precipitates in the weld nugget region [1].

The reduction of elongation at break with increasing filler loading is due to the decrease deformability of a rigid interface between the filler and PP/EPDM matrix.
The modification with MAPP as compatibilizer has increased the tensile strength of composites with an enhancement in rigidity and reduction of the ductility of composites, which consequently lowered the elongation at break of the PP/EPDM/CaCO3 composites.
Data DSC of uncompatibilized and compatibilized PP/EPDM/CaCO3 composites with different filler loading Composites Melting temperature Tm (0C) ΔH0f(com) (J/g) Xcom (% crystalinity) Xpp (%) PP/EPDM/CaCO3: 70/30/0 (Uncompatibilized) 163.33 55.50 26.56 37.94 PP/EPDM/CaCO3: 70/30/20 (Uncompatibilized) 163.86 46.49 22.24 38.15 PP/EPDM/CaCO3: 70/30/40 (Uncompatibilized) 162.87 43.41 20.70 41.40 PP/EPDM/CaCO3: 70/30/20 (Compatibilized) 164.39 51.53 24.66 42.30 PP/EPDM/CaCO3: 70/30/40 (Compatibilized) 163.35 46.74 22.36 44.72 CONCLUSION The presence of a compatibilizer, MAPP has improved the filler-matrix adhesion and consequently improved the tensile strength and modulus of elasticity but lower elongation at break of compatibilized PP/EPDM/CaCO3 composites.

Introduction According to the related statistics data, expected by 2030, fossil energy including oil, natural gas and coal still occupies the mainstream energy status in the world.
That’s China's strategy development direction according to optimize energy structure, fulfill commitment on carbon emission reduction and actively respond to climate change.
In order to change this situation, development and utilization of coal resources must be based on the core of circular economy, promoting clean coal production, circulation efficiency and energy-saving emission reduction, the exploitation and utilization of the demand for natural resources and ecological environment will reduce to the lowest degree with minimal resource consumption.

These data are of great importance for practical applications.
A reduction of E1 and E2, without loss in strength, was observed after HT 500-550ºC, Fig. 2 (b).
Further reduction of the modules in the state after HT 500-550ºC can be explained by RMT when the B2 phase (with higher mechanical properties [4]) appear, coexisting with R and B19' phases.
