It not only reflects the burning state of the materials being sintered, but also can be regarded as a criterion for determining the quality and quantity (Q&Q) of the product [2].
Fuzzy T-S prediction model for BTP BTP is the location on the trolley where the blending material burns completely, whose relationship with the vertical burning speed and the trolley velocity is as follow
If the permeability is good, the vertical sintering velocity is fast and the material burns easily; but if it is bad, the material burns with more difficulty.

Modeling or calculation with aid of rheology may be a promising approach to form a bridge over gaps in understanding between respective aspects such as workability test results, rheological parameters and practical behavior of fresh concrete, provided the knowledge will be established on how are workability and rheology affected by both raw materials and flowing conditions.

Introduction
The 4-axle side-tipping wagon 418V, internationally well-known as „side-dump car“ is designed primarily for the transportation of bulk and coarse-grained goods that are not moisture-retentive, such as limestone, coke, gravel, broken stone, sand, soil, coal and other loose materials of dimension more than 1 mm with a bulk density of 1.5 to 2.5 t/m³.
Modifications involve substituting selected steel elements with more durable and lighter counterparts made of composite materials, what would eliminate some of presented disadvantages.

Tests
The bird strike tests on flat plates were performed at AAMC (the Academy of Architecture Material in China).
The main objective of the experimental programme is to compare the response of LY-12 Aluminium plate impacted by substitute bird made from fowl under different velocity, and also the experimental results will be compared with numerical results to validate the correct of bird material parameter.

Introduction
The dump slag of metallurgical production remains the most popular in the manufacture of building materials and products.
It isn't subject to doubt that slag utilization as technogenic waste can be organized in such way to get not only building materials. but also metals which will be ready for further processing and use.
For non-magnetic parts that outpart does not exceed 10 % of the original weight of material.
Acknowledgements The research was financially supported by Ministry of education and science of the Russian Federation.

Abstract.
Introduction The use of organic materials like polymers in vapor sensors has been recognized to hold better promise for chemical specificity and systematic design of custom-made set of sensor elements [1].
Recently, conducting polymers, such as polypyrrole (PPy) [2], polyaniline(PAN)[3], polythiophene(PTh)[4], have been focused on as sensing materials due to the advantages of gas sensing ability, excellent performance at room temperature.
So, researches have been centered on chemically incorporating PPy within the matrix of other stabilizing materials [5,6], and PPy-insulator polymer composite using PVC [7], PTFE [8], PAI [9] and PMMA [10] have been studied as the supporting matrixes.

Although approximately 80% of coal ashes are utilized, most of which are low value applications such as land fill or raw material for cement replacing clay[1].
The use of fly ash as cementitious materials in concrete is still limitted for various reasons.
In the series 2 experiment, the air-entraining agent was regulated in order to get target air content, and other materials were used as the base mix proportion.

Introduction
Ceramic materials are considered to be suitable for structure parts applied at high temperatures and in extreme environment, for their outstanding performance in heat resistance, corrosion resistance, wear resistance, strength and rigidity.
On the other hand, the discovery of crack healing behavior of structure ceramic provided a new way to solve the problem of brittleness of ceramic materials[2].
Although the specimens were not heat treated at higher temperature, according to research about Si3N4/SiC particle composite, the strength of the material decreased obviously when the temperature went higher than 1300[4].
