Statistical analysis SPSS 13.0 software was applied to analyze all the data statistically.
All the data were described as mean ± s and were compared with t test.
Scores of the cohesion, emotional expression, successness, entertainment and organization in the 10 dimensions of Family Environment Scale in children in the asthma group were significantly lower than those in the healthy children group, especially the entertainment with the most significant difference, which could reflect good family structure factors, suggesting that it may be related to the reduction of outdoor activities and the limitation of activity scope caused by their allergic constitution in children with asthma.

This increases the possibilities in terms of large reductions and change in shape with less complex tooling and also reduces the required load capacity and cost of the forming machine.

The data were collected from the real output profile of each DGs power plant from December 2013 to June 2014 at 30 minutes time interval.
In comparing between no DGs, PV, biomass and hybrid system, hybrid generation accounts for the highest loss reduction, while without DGs connected to the system offer the least.
The collected data shows that midnight has the lightest load level, 08:00 a.m. represents the peak load in the morning, 12.00 provides the highest power output from PV plant, and19:00 p.m. represents the peak load in the evening.

First, it has nearly 8192 Bytes Flash Read Only Memory (Rom) and it can be updated by the application program, which resolve the difficulty of storing data.
In the typical microchip, it must store the data to the external memory parts, which increase Printed Circuit Board (PCB).

The reduction of the current, as a consequence of the flowrate increase, is related to the lower lifetime of neutral actives species in the discharge which decreases the ionization coefficient.
Now, we consider two situations: one corresponds to one data presented in Figure 2 (ton = 80 µs, t=40 min, T = 333 K and current = 0.12 A) for an Ar-10%O2 plasma and the other one corresponds to one data presented in Figure 4 (ton = 90 µs, t= 40 min, T = 333 K and current = 0.11 A) for an Ar plasma.

More boundary data of the numerical analysis on the rotor blade: y+ in the range from 1 to 10 near the wall of the rotor blade; Re number 7∙105 to 1.4∙106; far-field size (Fig. 4): 10 blade lengths from the rotor blade wind up and wind down, 5 rotor blade lengths radius wind up at the inlet, 6.66 rotor blade lengths radius wind down at the outlet.
Figure 5: Tangential moment on rotor blade root cylinder (left); decreasing residuals for momentum and mass (middle) and turbulence (right) 4 Results and Discussion The performance data of the unmodified model rotor blade were compared with real wind turbines in a thesis [8] in order to validate the model.
Figure 6: Streamlines on the clean blade (left) compared with the blade with fence and suction (right) Figure 7: Vorticity using the λ2-criterion on model rotor blade without flow elements vs. rotor blade with stall barrier with suction The reduction in the cross-flow can be determined by comparing the streamlines on the surface of the blade with and without flow element (Fig. 6).

The tests have been performed on universal testing machine TiraTEST 2300 with an automatic extensometers to measure both, the specimen’s longitudinal elongation and transversal reduction.
The section data of the major and minor strains was displayed and subsequently exported into the three separated files for each specimen.
The limit major and minor strains for each section of the specimen have been calculated according to EN ISO 12004-2 [6] when section data have been imported into the FLC mode of the Argus software – Fig 4.
