You will learn about the extraction of metal from minerals, wastes, and recycled materials, the design of metallic materials that possess desired mechanical, physical and chemical properties, and the production of components from selected metals and alloys [2].
The factors have led to a shortage of qualified teachers of practice teaching.
Some colleges and universities are forced to reduce practice time, compress content and simplify practice method, which greatly affect practice teaching effect.

Three factors render the Soil shear strength into a probabilistic problem: inherent uncertainties in the geotechnical parameters, model performance and finally human uncertainty [4].
There is a growing body of literature that recognizes the importance of soaking effect on soil properties alteration.
The soil properties are not considered unvarying during structures life [13].
The properties of soil used.
Statistical analysis of some geotechnical properties of Najaf city.

The design and fabrication were cost-efficient and engineered to not affect the continuous flexing of the soft fingers, addressing key challenges grasping with precision and efficiency.
In pneumatically controlled systems, the geometry of internal and external elements plays a crucial role, influencing factors such as shape, material composition, width, and air pressure source.
Mechanical System.
ABS and TPU were chosen for their respective properties and adaptability to 3D printing.
The force sensor detects mechanical stress when applied.

The discussion is focused on the consequences of the adsorption process on the structure and properties of both proteins and CNTs.
Although CNTs are not especially reactive, their hydrophobic character and good surface to area ratio provide very good physisorption properties.
The idea behind this growing research interest is to obtain novel nanomaterials with unique mechanical, electrical, optical, thermal, and molecular recognition properties to be applied in advanced biosensors and drug delivery systems.
The polymer layer protects the nanotubes from protein adsorption due to many factors such as steric repulsion, hydration, and solvent structuring at the surface.
Single-walled carbon nanotubes can be characterized by two integers (n and m) that determine its diameter and electronic properties.

The jet is a factor responsible for destruction.
To determine the strength properties of materials in the static range, a universal strength machine INSTRON was used, however, to determine the strength properties of materials in the dynamic scope/range, a stand with a split Hopkinson pressure bar was utilised.
The simplification were introduced to the model in such a manner that they do not affect the behaviour of the warhead.
If these properties are too small, the contact of the missile with the armour elements results in their fast extension.

Grinding agents influence essentially: - transfer of normal and tangential forces in ground stock in the way that enables a process of beating Al flakes into a required form and dimensions that results in tearing the flakes into smaller pieces within a defined range of sizes; - effective separation of the forming Al flakes that prevents the retroactive aggregation of the flakes into larger groups; - defined removal of surface electric charges from the volume of milling load that determines both the surface reactivity and the safety of production; - bulk material properties as well as dispersion characteristics of Al powders which have the greatest impact on processability of these materials.
In evaluating the pigments, the opacity properties of these materials are very often the key quality factor.
As these properties depend especially on the ability to cover as much bottom surface as possible by unit weight of the pigment, the fineness and lamellar shape of the pigment particles with smallest possible thickness are demanded at first.
The "mirror" tests of the covering properties of pigments in the form of hiding power test consists of measuring of a water surface that is covered by defined amount of pigment that skims over the surface [2].
This fact suggests that it is possible to optimize the kinetics of normal forces of the grinding beads which affect the Al particles in ground stocks by means of changing turns.

Oil palm fronds have large heterogeneous properties, and low bulk density presents problems for large-scale commercial bioenergy power conversion projects.
Further, this proves that temperature control is one of the factors that can increase the performance and productivity of a reactor.
As shown in Table 3, the use of temperature control does affect the temperature profile.
In other words, temperature significantly affects gasification reaction, produced syngas composition, and final calorific value.

The affecting factors are initial crack length, crack propagation and mean stress.
These factors make the fatigue crack propagation prediction tedious.
· Others are based on the mechanical properties which are easier to use as parameter calculation is deterministic.

Introduction Bone tissue defect and breakage owing to disease, senescence or accident are all long very difficult problem affecting human health.
The influencing factors during processing were illustrated and the configuration of final product was characterized.
At the first, put the A suspending liquid in the ultrasound generator and add slowly a difinite quantity of B solution into A with mechanical stirring and ultrasound application, keeping reaction temperature of 40°C～55°C and pH=10.5～11.5.

The model of material removal for RUFM was developed through examining indentation fracture mechanics theory and material removal characteristics of brittle materials, and analyzing kinematics properties of diamond grits in RUFM.
However, because of its mechanical characteristics, it is one of the most difficult-to-cut materials [1].
ZHOU et al.[10] reported that cutting force is an important factor affecting the size of the stress field exerting at the work material beneath the tool tip and the scale of deformation.
The material removal model for RUFM of brittle material processing by diamond tool was presented through examining indentation fracture mechanics theory and material removal features of brittle materials, and analyzing kinematics properties of diamond grains.
