The remaining three countries, Italy, Hungary and Portugal, opted for location sampling (Centres of Aggregation Technique), which entails selecting a number of locations where immigrants are likely to be found.
For vegetation (tree and understorey plant) sampling, centred on each sampling station, plots of 50 m ×50 m were established.
Twins at the sample centre and front surface were created by the shock wave front.
With mechanical properties determined at the sample centre, results demonstrated that the materials appeared to become stiffer and less extensible with less slender sample geometries, suggesting that fibre recruitment increases with decreasing sample arm length.
And for aluminium sample, comparing with the grains in the sample centre, the grains in the sample up boarder area are more sensitive to the ultrasonic vibration in terms of grain refinement, while for the titanium it is on the contrary.
SUA in ARIC was corrected for sex, age, body mass index (BMI), serum creatinine, hypertension treatment and sample centre.
Representative renal samples (centre and poles) and renal lymph nodes were fixed in 10% neutral-buffered formalin for minimum 48 h.
The region of interest was scanned in a standardized way to include the impact area itself and the immediate adjacent concentric area; more specifically, the sample centre point (i.e., centre of impact area) was included but provided the centre edge of the scan area which extended 10 mm to the periphery as defined by the peripheral edge of the scan area.
Anomalies are calculated using 1979 2000 as a baseline and black dots represent differences between the mean of the 5-year sample (centred on point) and the baseline that are statistically significant (P<0.05).
This corresponds to a window of length 128 samples centred around 0.315s, (b) power spectrum, (c) bicoherence.
