The Aluminum properties are; the melting temperature (933k) and the solidification temperature (300K).
Figures (7) and (8), where the bold circle represent the mould cavity perimeter when the solidified part is clear at different locations along the cast (5mm, 15mm, 25mm, 35mm and 45mm) below the cast upper surface, the base of the inverted cone on the cast upper surface also affected by the applied press on it and the mould thickness, where its perimeter decreases with increasing these factors.
A new case named (Case2_2_A) have been used at 310K ambient temperature with the same geometry, properties of (Case2_2).

Additionally humidity induced swellings of machined edges are possible – especially at thermoplastic matrices. [7] Humidity also affects the mechanical properties of the CFRP.
With advanced experiments, in consideration of additional influencing factors, the potential of dry lubricants on the basis of graphite at CFRP-drilling should be further investigated.

Quality of final product is directly affected by these tools.
The friction coefficient is seen to be an important factor for the drawability of large size products.
In this method, wrinkling criterion proposed by Cao and Boyle [5] is used, which assumes that the initiation of wrinkling is a local phenomenon and depends on the material properties, stress state and sheet thickness.

This paper will try to discuss brittle fracture of polycrystalline materials in the light of the roles of grain boundaries and of the grain boundary microstructures, based on recent knowledge of grain boundary structure and properties established in the last three decades [5].
When intergranular fracture occurs ideally without any plastic work (this is the case of very brittle materials), the fracture energy almost directly affect the fracture energy and fracture strength.
Factors Controlling Crack Propagation in Polycrystal as Percolation Process (a) In-situ Observations of Fracture Processes in Polycrystals So far there was a very few literature reporting in-situ observations of fracture processes in polycrystals with characterized grain boundaries.
This was a very important finding that the grain boundary character distribution can affect operating fracture mode.

Unfortunately, as devices become smaller so they can interact with individual cells, they fail chronically in-vivo which has been attributed to both abiotic and biotic factors.
Carbon-electrode SiC INI Carbon containing materials, such as graphene, carbon-nanotubes (CNT), and graphene oxide, have gained prominence as possible electrode materials for implantable neural interfaces due to their excellent conductive properties.
The C sandwiched with a-SiC was characterized for both its material and electrical properties as shown in Figure 6 below.

Besides, in previous research done by M.Casadio et.al, they ignored the damping factor by stating that it does not represent any physiological meaning [5].
However, Ishida and Agarwal was against that assumption in which they suggested that stiffness and damping properties can describe passive properties of muscle fibers and tendons [6, 7].
The change of angle over time will determine the way of ankle joint counteract against the oscillation of perturbation which is may results from evoking the intrinsic mechanical properties of ankle joint, and muscle contractile elements which triggered by the CNS.
Types of external disturbance somehow maybe affect the stiffness produced by the ankle joint.
Further investigations in determining estimation of stiffness pattern of hip joint and also muscle properties, in particular under different frequencies of translation perturbation are warranted in order to develop a reliable measurement system to measure balance ability and motor learning.

The middle part of the settled melt was then transferred to the second pot via a mechanical pump in order to separate the cleaned melt from the sludge.
Variation of the properties of the ingots recovered from steering wheel scrap: (a) area percentage of inclusion particles; (b) tensile elongation to fracture; (c) corrosion rate under immersion in 3.5% NaCl aqueous solution. recovered ingots gradually increased in accordance with a decrease of their NMI content, which was coincident with the results in other literatures [8-9].
Therefore, another factor would affect the corrosion rate of the recovered ingots judging from the much lower NMI content in the present study than those of Wang’s case.

Another important factor is also the porosity of the catalyst.
Acidic properties were generated by aluminium doping and grafting with sulfonic groups.
The surface area, macropore volume, mesopore volume and acidic properties of the prepared catalysts have been tabulated in Table 1.
The experiments were carried out in order to establish the influence of water on the catalyst's activity, as it has been proved that water could have either negative or positive effect on methanol conversion depending on the catalyst's properties [11].
