One of the most important factors for producing nanofibers using solution electrospinning is their concentration.
As mentioned above, factors that affect electrospinning process are varied, such as the surface charge, the injection pressure, the collect distance, the flow rate and the nozzle diameter.
Size, shape and collection methods may provide a potential approach to produce fibers with new properties.

This means that the evaluation of the structural behavior has to be approached through an assessment of the current condition of the structure and its history in term of material properties, construction techniques, structural details, crack pattern, damage map, and material decay [5].
The occurrence of decay is not isolated but almost always part of a more complex process that involves physical and chemical environmental factors, and the structure and design of the building also.
Structural Details of the Aghjots Monastic Complex The structural analyses of a new masonry building is a relatively simple task, however the assessment of the seismic vulnerability of an ancient masonry building is a challenging task, because of several uncertainties affecting the geometrical and the mechanical characteristics of the structural elements [6,7].
Also, it has been affected from time effects.
Mechanical damages in structures of Aghjots Monastery results when stone is subjected to a load or a stress that is above the mechanical resistance it has.

The eutectic microstructure determines the mechanical properties of the Al-Si alloys because eutectic phase contains a hard, brittle silicon phase in a softer α-Al phase.
Therefore, controlling the eutectic silicon morphology by modification had been extensively used in industry to improve the mechanical properties of the castings.
A significant quantity of research work has been conducted in recent years to study the efficiency of various modifier elements such as Sr, Na and Sb on microstructure and mechanical properties of cast and semi-solid A356 alloys.

However, the porous charateristics of the concrete materials easily lead to ions erosion, which is one of the factors affecting concrete durability.
The erosion of concrete and mortar causes the changes to its mechanical properties and therefore phenomena of erosion damage occur.
So, the macro-properties and microstructures of different concretes were investigated in this paper.
In this study, the superfine slag was selected to improve the concrete’s performance, and the properties of slag is shown in Table 2.
The more slag mixed concrete,the fewer internal erosion factors there are,and then the concrete has better corrosion resistance.

Effect of Oxygen on CVD Diamond Film Deposition Yuan-Sheng Huang1, 2,a, Cheng-Ping Luo2, Wan-Qi Qiu2 1 Department of Materials Technology, Jiangmen Polytechnic, Jiangmen 529090, China 2 College of Mechanical Engineering, South China University of Technology, Guangzhou, China a nightofgz@163.com Keywords: diamond film, chemical vapor deposition (CVD), oxygen Abstract.
Introduction Similar to nature diamond, CVD diamond also shows excellent properties such as high hardness, good wear resistance, low friction coefficient and high thermal conductivity.
The CVD diamond films with a smaller grain size showed a better mechanical property and a better adhesion with the substrate.
The factors affecting the CVD diamond deposition include deposition atmosphere, temperature, substrate, etc [4，5].

And then, based on the forecast results, the interval of the groundwater correction factor K1, main strike-dip of structural surfaces correction factor K2, the initial stress state influence correction factor K3, which affected basic quality indicator of surrounding rock BQ were divided.
As an important branch of underground engineering, it is susceptible to all kinds of natural and man-maid disaster, which may cause a serious loss of life and property.
This paper made use of geological advanced prediction combining with engineering geology method to measure the change of rock elasticity wave velocity, in order to confirm three parameters which affect BQ, and then BQ could be corrected, so that the surrounding rock classification during construction period could be done.
Modifying BQ according to the geological exploration material, get revised basic quality indicator of surrounding rock [BQ], which could be calculated as below: (2) Where K1 is the groundwater correction factor, K2 is main strike-dip of structural surfaces correction factor, K3 is the initial stress state influence correction factor.

Tool wear is easy occurred in titanium alloy milling process which will affect the surface quality.
Therefore, the study on the relationship between tool wear and surface quality is significant for improving the surface integrity and fatigue property.
The influence of flank wear on surface qualities and chip morphology are analyzed through milling single factor experiment of the maximum flank wear.
These defects will cause stress concentration, partial wear increases, deteriorate properties of parts and affect service performance and life of parts.
Chips morphology is one of the most important factors that will affect the surface quality [14].
