Conventional repairs involving complete replacement can be time-consuming and expensive, and the reduction of service loads with existing cracks is questionable, so quick, simple and economical crack retardation methods seem to be the best option and the most used.
The reduction of crack tip stress concentrations can be achieved by the stop-drilling technique.The stop-drilling technique or SD is an emergency procedure fairly popular in the aeronautical industry.
Hence, it is important to the aeronautical industry and scientific knowledge to develop some experimental data related to SD fatigue life on thin plates of Aluminium.
Numerical results were compared to experimental data values.

Introspection on Anti-Seismic of Rural Housing Weijian Li1,a, Changqing Gong1,b and Xiaosong Ren1,c 1Research Institute of Structural Engineering and Disaster Reduction, Tongji University, Shanghai 200092, China a lwj060949@163.com, b8changqing_gong@tongji.edu.cn,crxs@tongji.edu.cn, Keywords: rural housing, seismic performance, macroscopic measure, technological measure, collapse resistant capacity Abstract.
According to the data on the State Statistical Bureau website, the per-capita living space of rural dwellers increased from 8.1 square meters in 1978 to 33.6 square meters in 2009, which shows that rural housing construction covers tens of billions square meters.
Macroscopic survey data indicated that all together 63 thousand households’ rural houses in Qingchuan county collapsed or were severely damaged in the earthquake, which was a great earthquake disaster to a county with only over 200 thousand population, and the total direct loss reached 4.7 billion Chinese Chinese yuan [9].
For farmers, work should be started with ensuring the sustainability of the real estate and taking the huge casualties and losses caused by earthquakes as the specific content; for all executives, seismic fortification should not be ignored, make clear the idea that disaster reduction equals to benefits, increase some expense for seismic fortification which is usually within 5% of the cost of construction as estimated, encourage policy measures and financial support for the construction of rural seismic resistance.

Table 5 presents critical content data of toxic components.
Due to the resulting gas it is reduction of organic matter.

Meanwhile, ozone causes the imbalance of biomass allocation and nutrient absorption in the plants, which lead to biomass and yield reduction [4].
The data of E40 was considered as the control in this study.
Data Analysis.
A significant reduction of the stem biomass of plants could be induced by ozone [23], however, the response of different trees were different when they were under ozone stress.

As illustrated in Figure 1 that how these objectives are connected with more widely accepted measures for car travel reduction [17].
Figure 1: The role of park-and-ride in car travel reduction [17] Factors that influence choice of travel mode.
Although, discrete choice models can be established on either observed behavior (Revealed Preferences data) or on hypothetical choice surveys (Stated Preference data).

Introduction Multiferroics has been attracted much attention due to the mutual coupling between magnetic and electric properties, which has the huge potential application in multiple-state memories[1] and data-storage media[2].
This indicates that annealing treatment for pure BiFeO3 improves the leakage current due to the improvement of crystallinity, which is consistent with reduction of leakage current density for doped BiFeO3 thin film by high temperature annealing [15, 16].
As reported that La ions substitution on Bi sites suppressed the secondary phases leads to the reduction of leakage current [17].
In our case, annealing effect induces the formation of the secondary phase in BiFeO3 crystal (reflected from XRD data), which would be supposed to increased the leakage current.

The results were compared with experimental data for some cases such as vertical plate and horizontal circular cylinder, the agreement was excellent.
Good agreement with other experimental data was achieved.
The stream function (y) and vorticity (w) in the governing equations are defined as follows, Anderson [10] and Petrovic[11]: (6) (7) Or The stream function formulation satisfies continuity equation and substituting these in equation (1) yields: (8) By suitable manipulation, the pressure terms in the governing equations may be eliminated, yielding: (9) (10) In the stream function-vorticity formulation, there is a reduction in the number of equations to be solved in the y-w formulation, and the troublesome pressure terms are eliminated in the y-w approach.
Decreasing the enclosure width reduces the convergence time of Nu and mass flow rate due to the reduction in the enclosed mass and hence inertia within the enclosure.

These may be admixed in the load within the metallothermic reduction or in the form of metals and other compounds, among such fluorides.
The data provided in the table 4 indicates that diffusion coefficient and kinetic constant for oxides Dy and Tb make up by 573 К: 0.39∙10–9 and 2,4∙10–4; 0.26∙10–10 м2/sec and 0.79∙10–4 m/sec.
Initial data of X-ray analyses and some results are shown in the table 5.
On the basis of acquired data one may draw a conclusion that performance of a neodymium oxide fluoration can be accomplished with a cheaper fluorating agent - ammonium fluoride.
Kinetics of fluoration of dysprosium and terbium oxides has been studied and diffusion-kinetic model for mathematic processing of experimental data has been selected.

Through the statistic data we can see that Web has developed into distributed information space.
Galois lattice is its core data structure of the theory of FCA.
So it is very suitable to process data mining from database.
Hence, Galois Lattice is used as an effective tool for data mining and knowledge extracting.
The dimension reduction of the formal context is also one of the future research directions.

Then do interleaving to prevent unexpected errors led to a continuous piece of data in error that can’t be corrected.
After that, the data must been serial/parallel transformed to reduce the rate of data flow and mapped into two parts, the real part and imaginary part, to improve the spectral efficiency of the channel.
The whole module is made of the memory controller, the butterfly unit, the data pipeline module, adder and the external RAM memory.
The data of each subchannel can be expressed as the following formula: D = (I + jQ) KMOD, it represents each subchannel data.
