Addition of graphite powder increases its electric conductivity, hence, introducing new functionality to building materials such as self-sensing and self-heating properties.
The mechanical properties and application possibilities of AAS are very similar to OPC based materials.
Although graphite is added to improve the sensing properties of the building material, it should not deteriorate its mechanical fracture properties.
Addition of graphite also affected fracture properties.

The gelatin is a kind of natural polymer with the unique physico-chemical property [3].
The property of no crosslinked gelatin is hard and fragile and its mechanical property is also poor.
The property is beneficial to recycling of the adsorbent after dealing with the dyes wastewater.
The morphology of gelatin microspheres is almost not affected.
When the temperature was 30℃ above, the desorption rate tended to constant and the thermodynamic control was the dominant factor.

Durante et al. [15] proposed an analytical model to calculate the relationship between the surface roughness and ISF parameters, including vertical step depth, wall angle, and tool radius of the forming parts, with a mathematical method that did not take the material properties and deformation of the sheet metal into consideration.
Design of Experiment To estimate the influence of the processing parameters on surface profile accuracy, a design of experiment with four factors and two levels for each factor was used with three replicates.
Effects of combination of parameters Figure 13 shows the main effect plots for the two significant factors of tool diameter and sheet thickness.
Figure 16 Effects of step size and tool diameter on surface roughnes [25]. 5 Conclusions This article presented the process parameters affecting the surface roughness.
Here are the factors to consider: • To improve surface roughness, a larger tool diameter (D) must be accompanied by a smaller value of step size (Dz) and a larger value of feed rate (f) so as not to adversely affect the ISF limit

The capillary number of the cross-flow turns out to be the key factors in the droplet generation process.
Song [1] found that use of different types of fluids for the flows can affect the droplet generation.
From their work, the capillary number and the relative flow rates of the continuous and dispersed flow were found to be two important factors for drolet generation.
The properties of the fluids.

Among its most important properties we can highlight the following: it acts as a barrier for gases, such as CO2, humidity and O2.
However, today this material seriously affects the environment worldwide, not only on land, but also in all ocean areas, significantly compromising the marine flora and fauna Analysis and Method The present research is of a descriptive type; it aims to describe in detail the characteristics, pros and cons of the different properties that PET bricks have in traditional bricks.
Physical and Mechanical Properties The physical and mechanical properties of the construction elements developed were established by means of laboratory tests
This optimizes the time, which leads to a lower cost and development in construction factor

No less important factor is the feeling of comfort, for example, by evaluating the fabric properties by hand touch and body feelings while trying on for mechanical effects (size unconformity, irritations), warm/cool feelings, and comfort during everyday movements.
Manufacturers and retailers should take these factors into account because ultimately consumer becomes the final judge of whether the product has the desired quality and if quality characteristics are defined as product characteristics related to requirements [1,2].
Drapability covers a variety of fabric factors: stiffness, flexural rigidity, weight, thickness etc., which in turn depend on the geometric parameters of the fabric, finishing agents, yarn, yarn interaction, a method of construction etc. [5].
Designers, developers and manufacturers are challenged to make various decisions about the preparation of wear test plans, such as the purpose of the wear test, the properties to be evaluated, the performance of the evaluation, the number of included samples and time period of testing trials [1,7].
Appearance evaluation of ready-made garments is done visually by photography under set conditions so that the assessment is not affected by the environment – lights, shadows etc.

Graphene is presented to be the prominent candidate to be used as channel material in FET which widely known as Graphene Field Effect Transistor (GFET), due to the remarkable electrical, physical and mechanical properties of graphene [4-7].
Damage in materials is caused by the interaction of the energy with the nuclei and orbiting electrons, thus should also expect changes that will occur in physical, mechanical and electrical properties of materials [13].
In the previous work, the electrical properties of irradiated graphene was discussed only at voltage of 1.0 V and 2.0 V.
This situations happens due to the high dose of the irradiation that alter the uniformity of the electrical properties.

Analysis on Cogging Torque of Permanent Magnet Synchronous Motor for NC Machine Tool Servo-System Shenbo Yu1,a, Hui Dong1,b, Xin Feng1,c, Jing Yuan1,d 1School of Mechanical Engineering, Shenyang University of Technology, Shenyang, P.
Simulation models of PMSM are established to complete coupled calculation between magnetic fields and mechanical dynamics.
A “goodness” factor, which is proportional to the slot number and the pole number and inversely proportional to their smallest common multiple, was introduced by Zhu, Z.Q..
The conclusion of the higher the “goodness” factor the larger the cogging torque was drawn[4].
The properties of motor, for instances, heating-up, vibration, noise and torque, are closely influenced by the slot width, while cogging torque is obviously affected by configuration of the stator slots opening.

However, there is no further research on how physical structure and properties of composite carriers would affect the kinetic properties of the immobilized enzyme.
Determination of optimum pH The pH is one of the most significant factors that affect the enzyme-catalyzed reaction.
Kinetics of immobilized chitosanase with different carriers The Km value is considered to be as a measure of affinity between the enzyme and the substrate, which would be affected by carrier with electrical properties.
One is the electrical properties of carrier that affect the affinity between the enzyme and the substrate, the other is the spatial three-dimensional obstacles or diffusion resistance of the immobilized enzyme which can lead to Km value increasing.
The results showed that the pH and Km values of immobilized chitosanase were significantly affected by electrical properties and spatial three-dimensional obstacles of carriers, respectively.
