Theoretically, the presence of anionic substances in the water used for preparing cationic polyelectrolytes has been shown to be the most detrimental factor to its efficiency.
Different from the behavior when CPAM was dissolved with white water, the retention efficiency of the dual retention aids system was affected significantly by the white water used for the preparation of bentonite.
It was indicated that the fixing function of PEI was not affected by the impurities in white water, then it is possible to use purified white water to prepare PEI. 4-a.
The flocculation function of bentonite in dual retention aids system was significantly affected by the white water used for its preparation, the fines and filler retention efficiency was decreased significantly.

This paper summarizes the properties of the CFC as well as the appropriate material and geometry of the cutting tool that should be used when drilling of the CFC in order to optimize the drilling performance.
Furthermore, higher cutting speed and lower feed rate are also recognized as significant factors which contribute to rapid wear of the cutting tool.
Introduction Composites are advanced engineered materials which have outstanding performance due to the combination of superior properties from two or more different materials within them [1].
Furthermore, the fibreboard contained high composition of sulphur which can react with cutting tool during machining and oxidation of the cutting tool would also occur when it is operated at high cutting temperature and these factors weakened the cutting tool.

They provide a sufficient level of the briquette mechanical properties.
The role of binders in the technology of briquetting is great, since these substances provide the strength properties of briquettes [2].
Since the materials for briquetting are very diverse, every time the problem arises of bringing evidence of the briquetting process efficiency and achieving the necessary briquettes strength properties.
Methods for the determination of mechanical strength).
In briquetting practice, it is known that denser briquettes, as a rule, have better mechanical properties.

Mechanical properties Due to its superior mechanical property, the carbon nanotube composites are used in sensors and innuclear transportations.
The outstanding electrical property of nanotube compositesis mainly dependent on two factors such as diameter and geometrical property of the nanotube which are the major factors responsible for the fluctuation of the conducting and semi conducting behavior of the nanotubes [8].
The carbon nanotubes possess unique mechanical and thermal properties with higher stiffness and strength.

This study is part of a research project which main objective is the development and optimisation of AlN(Er) thin films with luminescent properties suitable for use as sensors in the evaluation of wear and corrosion strength of mechanical components.
The mechanical properties of the AlN(Er) films are not committed by thermal annealing.
Introduction Aluminium nitride (AlN) exhibits excellent physical, chemical and mechanical properties, which make it potentially useful for a wide range of practical applications.
In a previous work AlN(Er) films were deposited by magnetron sputtering and the mechanical behaviour as well as the photoluminescence properties of the films were evaluated.

This analysis model allows various analysis approaches to be applied to the conditions affecting the construction of a large gantry crane in order to ensure the stability of the mast of the crane.
Such accidents may result in human injuries and in property damages.
Factors affecting a crane's hoisting load, such as its weight and design, have been applied when considering its vertical load.
Such factors include the shape of the entire structure of the box, wind loads acting on the transverse direction, and any weaknesses in the structure.
The safety factor is applied as follows in Table 1.

Predicting the deformation and resultant properties helps in developing process parameters and tailoring coatings to get the desired properties.
The process can be used to build up thick layers of material with very little porosity, high bond strength, and good mechanical properties [1-2].
Several of these properties are affected by the amount of deformation the particles undergo during deposition.
Other factors that affect deposition and particle deformation include the particle temperature, tensile strength, and degree of work hardening.
