Once passing 35%, the property will be worse.
When the alkali concentration reach a certain value, the active factor of the raw material release fully.
Therefore, to meet the aluminosilicate depolymerization conditions and no affecting the monomer polymerization, a reasonable range of alkali concentration can make balanceable between depolymerization and polymerization.

A bond structure forms at the metal-ceramic interface by physical, chemical, mechanical and diffusion bonding mechanisms [1-6].
Chemical and mechanical bonding, thermal coefficient of expansion, sand blasting, oxidation, bonding agents, high amount of elements present in the metal and ceramic structures, properties of metal and porcelain powder, sample preparation and firing conditions are the factors that affect the bonding strength at the metal-ceramic interface [7-12].
Experimental This study is for the characterization of the interface properties between metal-porcelain diffusion couple in porcelain teeth.
These bonds may be due to atomic diffusion of the species across the interface, chemical bond between metal and ceramic atoms, chemical reactions that occur at the interface and mechanical interlocking of two parts.

Among the general risk factors we can include possible infections, osteoporosis, rheumatoid arthritis, treatment with corticosteroids, and naturally other diseases which may affect healing processes in patients.
New design (structure) Proper mechanical properties and reliability of structure: Stiffness of fixators, fatigue tests of the whole system, etc. are based on laboratory testing of new smart materials.

This is without factoring in the scale layer on the drying cylinder surface.
Analysis of Disturbance Influence on Water Ring’s Movement and Heat Transfer Properties.
The factors influencing the stability of liquid membrance include and. represents the influence of inertia and viscosity.
The siphon clearance directly affects the quantity of condensate water in the drying cylinder.
Based on steam properties listed on a table: the h2=2 733.81kJ·kg-1 when the saturated steam in drying cylinder was 140℃; Inserting h2=2 733.81kJ·kg-1; c1=0; c2=50m·s-1 into formula (4), produces the following result: h1=(2 500÷2)+2 733.81×103=2 735.060 kJ·kg-1.

Coating properties show improvement with addition of less than 3wt% clay content.
Clay has been conventionally more popular in providing thixotropic properties [1,2].
Table 1: Sample codes, TEM and SEM particle sizes, and PUC coatings properties.
Factors such as dilution of clay with respect to amount of polyurethane, peak broadening and preferred orientation of nanoclays make XRD characterization of polymer nanocomposites susceptible to errors [5,13].

Recent development trends, as urbanization, in combination with the occurrence of more and longer lasting weather extremes, are responsible for more frequent events with severe impacts on human lives and properties.
Two approaches for the determination of susceptibility maps are the most promising: (a) methods based on the statistical analysis of geo-environmental factors related to the occurrence of landslides; and (b) deterministic modelling based on simple mechanical laws that control slope instability.
Multivariate statistical models provide the best results for large areas especially at cases where the determining factors and landslide occurrence are complex.
I have personally accepted that the evolution of the Greek city-states resulted from the combination of the following three factors: i.
Many other factors, such as the size of groups of people, their level of education, the progress of their technology, outside forces, etc.”

The sliding friction between the ring-like electric cable guider with round steel structure and the cable can wear down the electric cable very seriously and affect the electric cable’s service life. 2.
The opening angle of the spindle shaped block is the key factor that affects the performance result of the slide block.
The abrasion in the screw drive is related to such factors as the contact stress on the working surface, the sliding speed, the contact surface roughness and the lubrication status, among which the most important factor is the contact stress on the working surface, for too big contact stress can bring about excessive abrasion.
High molecular material should be adopted to manufacture the spindle shapedblock to ensure favorable physical properties, abrasive resistance and self lubricity to make it more able to meet work demand.

For evaluating the effect of laser application in real time and ensuring the optimal effect in LITT, exploration the changes of optical properties and temperature distribution in tissue, and their correlation are indispensable.
Previous studies have proved that the optical properties of biological tissue are affected by thermal coagulation.
The aim of the present study was to find the variation tendency of the reduced scattering coefficient on fresh porcine liver in vitro during LITT, and to explore the correlation of optical properties and temperature.
Discussion Existing studies show that the optical properties of biological tissue will be influenced by thermal effects.
In contrast to the scattering coefficient, the absorption coefficient changes slightly[10-12], anisotropy factor is approximately a constant[10].

It is well known that the Hall-Petch coefficient, ky, significantly affects YP through grain refinement, and it is suggested that the segregation of solute carbon in the grain boundary could affect to ky[8,9].
These facts indicate that the grain boundary affects aging behavior in some specific aging conditions and could be one of the essential factors of strain aging, however, its detailed effect and hardening mechanism have not been clarified.
