Introduction Human teeth are subject to many and varied destructive factors such as mechanical and thermal loading, caries, abrasion, erosion, and aging as well as restorative and endodontic treatment intervention [1].
The thermo-mechanical properties of the polymer-based resin composites currently commercially available in restorative dentistry can vary in a very wide range [27].
Unfortunately, it is not clear how these properties affect the life of restored teeth.

Properties of the cable sheathing compound.

It is affected by a variety of factors such as the quantity of constituents, the water/cement ratio, the duration of hardening, the size of granules, the temperature and superplasticizer [9].Dwi Sri Wiyanty et al. concluded that adding a superplasticizer and reducing the quantity of water in the mixture increased the compressive strength of concrete and was influenced by the fine and coarse aggregates[10]. 
The water-cement (w/c) ratio is an essential factor in determining the properties of concrete.
Furthermore, the concrete classes commonly used in local practice (C10–C35) have not been sufficiently studied in terms of the relationship between their mechanical properties and the actual deflections of beams. 
To study the mechanical properties in a fresh and hardened state, six concrete compositions are prepared.
The input properties for steel used are presented in Table 7.

Study has shown that an external magnetic field can improve tribological properties of ferromagnetic materials, and have an impact on paramagnetism materials and anti-magnetic materials [2, 3].
The introduction of electromagnetic field in the friction-abrasion testing machine attracts wear debris and lubricates particles, which affects friction and wear process directly, and affects the microscopic behaviors of the friction and wear process.
Table 1 lists the properties of the two materials.
(2) In the coupling process of electromagnetic induction heat and mechanical friction heat, when the stress and rotational angle are constant, the change of coupling temperature will be affected by the electromagnetic induction frequency, the linear velocity and other factors.

The article discusses the spatial analysis of the chemical soil properties that is a key component of the agriculture ecosystem based on satellite images.
The soil type of Sanam mountain region is rocky, most of the rocks suffered from mechanical and chemical erosion factors due to rain and wind, and the great discrepancy between day and night temperature, which has a noticeable effect on the mountain rocks and the surrounding regions.
The spatial analysis of TDS, EC, and pH for the soil are influenced by structural factors, such as climate, parent material, topography, soil texture, and other natural factors.

Introduction High performance polymer materials were widely employed in the mechanical moving parts of the space systems, due to their excellent mechanical properties, high strength/weight ratio, good chemical inertness and easy manufacture.
It was approved that proton irradiation could also affect the tribological properties of the PI composites [5,6].
Additionally, some scholars investigated the other radiated factors, such as vacuum, ultraviolet, and electron [7-9].
Although abundant publications about the effect of the individual radiated factor on the properties of the polymers had been reported, there seemed few researches on the sequential irradiations with AO and proton.

In the binary bismuth chalcogenide family, Bi–Te based and Pb–Te based [5, 6] materials showed the best TE properties at room and middle temperatures, respectively.
However, complex substitution and interstitial Cu atoms make the crystal structures of Cu3.21Bi4.79S9 highly complex and disordered [8], hence, better TE properties are expected for this material.
Hence, a parameter thermoelectric power factor (S2σ) was calculated to estimate the actual improvement in thermoelectric properties (Fig. 5).
