Characterization data confirms the presence of functional groups on the material's surface that will interact with lead metal and CaCO3 decomposition caused by calcination temperature treatment.
The results of the mass reduction can be seen in Table 1.
Based on Table 1, the mass reduction of the biosorbent is 6.4% for a temperature of 700°C and 4.6% for a temperature of 500°C, respectively.

However, this improvement in mechanical strength is accompanied by a higher compression set, suggesting a potential reduction in sealing efficiency due to diminished elasticity and recovery after deformation.
This reduction in elongation is indicative of a transition from a more flexible material to a stiffer, more brittle one, which is a common trade-off observed in reinforced rubber composites.
The data indicate that the compression set increases with the addition of higher carbon black content.
This reduction in contact pressure may result in micro-gaps forming between the seal and the shaft, allowing for fluid leakage and the potential ingress of contaminants.
The reduction in volume loss with higher carbon black content can be attributed to the reinforcing effect of carbon black, which significantly enhances the wear resistance of the NBR.

A finite element model considering the high-speed train excitation loads, track structure, vibration reduction measures, station structure, characteristics of foundation soils was established to study the problem of vibration in the underground Futian hub of Guangzhou-Shenzhen- Hong Kong high-speed rail.
Compared to conventional ballasted track, ballastless track has a relative higher stiffness, thus the vibration and noise is relatively serious[14], vibration reduction measures are always needed.
Combining with the geological data (Table 1), the normal spring coefficient can be determined by this method.
Comprehensive analysis of vibration reduction effect is shown in Table 3.
Conclusions A finite element model considering the high-speed train excitation loads, track structure, vibration reduction measures, station structure, and soils was established to study the vibration in the underground hub.

Conventional product upgrading methods [2,3] typically focus on the physical product performance enhancement, product upgrade side effects, or over-specifications necessary to alleviate those side-effects but neglect quantitative considerations of the reduction of the environmental loads attributable to the upgrading process.
This work proposes an upgrade product design method that focuses not only on product performance enhancements and side effects, but also on expected reductions in production cost and environmental load.
From the results of the application, an upgradeable product demonstrated the feasibility for satisfying the requirements of the enhancement of product performance, and concurrent reduction of environmental load and production cost.

Lower Heating Value Estimation of Coal Gangue through Proximate Analysis Data Based on GB/T 212-2008 Xiu-Teng WANG1, a, Bin LU2, Ling XU3, Chenyi LI3, Ling LIN1 and Jin HUANG1 1Subinstiture of Resource and Environment, China National Institute of Standardization, Beijing, 100191, P.
Herein, we use an alternative approach to estimate the heating value based on proximate analysis data, which are measured under the instruction of GB/T 212-2008.
One of the alternative approaches is estimating heating value based on proximate analysis data as the calorific property of fuel is determined by the chemical composition.
Namely, according to the physical and chemical properties of different components in the coal gangue sample, they are decomposed or combusted under different temperatures and the mass fractions of the components can be worked out as the percentage of weight reduction.
From the calculation data of our work, we can see that the LHV of these six samples range from 2307 to 8309 kJ/kg.

According to the results of [21], some carbon residue is inevitably present in the products of carbon-thermal reduction.
The disadvantage is the lack of data on the reduction of complex oxide compounds, which may be part of man-made raw materials.
This can lead to probable differences in the course of the reduction reactions.
However, in [20] the reduction is accompanied by the formation of carbides Cr3C2, Cr23C6, Cr7C3.
This is in good agreement with the results of works on the reduction mechanism of W [18, 19] and Mo [17] oxides.
