Examples Of The Method That's Also Aiding IOX2-Pros To Grow

The sample dimensions were selected according to standard ISO 1567 for comparing the tensile strength of samples with the control level.23 Sample size was determined according to a pilot study carried out on 4 samples. Using power-spread with �� = 0.05 and power = 80, the results obtained from the pilot study indicate that 9 samples are required in each group. Four study groups, 9 samples were prepared for each test and totally, 36 samples to determine the mean number of specimens required for tensile strength tests. The TiO2 nanoparticles were characterized using XRD (Philips X��pert, Cu Ka radiation) for crystalline structure and particle size. Also, scanning electron microscopy (SEM, VEGA/TESCAN) was used to study morphology of samples. Each specimen was tested for tensile Diosmetin strength according to ISO 1567. Specimen plates were formed into a rectangle (60 �� 12 �� 4 mm) with a metal mold (n = 4). Rectangular specimens were then divided into 4 groups of 9 samples as follows: (1) acrylic resin as a control; (2) acrylic resin containing 0.5wt% TiO2; (3) acrylic resin containing 1wt% TiO2; and (4) acrylic resin containing 2wt% TiO2. Surfaces of all the specimens were polished using silicon carbide papers (mesh numbers of 500�C2000). The tensile strength test was conducted with a universal testing machine (Zwick Z100, Germany) at a crosshead speed of 5mm/min under a load cell capacity of 10 kN to obtain stress-strain curves. Figure 1 shows the tested sample in test machine. HIF activator Elastic modulus was determined according to the slope of the linear section of stress-strain curves. Modulus of toughness was calculated by measuring the entire area under Androgen Receptor phosphorylation the stress-strain curve from origin to rupture. Figure 1. After testing, all results were analyzed by statistical methods. Mean, average, and mod in each group calculated and normal distribution curve was evaluated. Kolmogorov-Smirnov test was used to evaluate normal distribution. Statistical analysis of the obtained results for each test group was conducted using a one-way analysis of variance (ANOVA) followed by multiple comparison test (Scheffe��s test). Statistical significance was set at P
