The optimized norfloxacin pellet batch in terms of sphericity and hardness was selected followed by incorporation of NaHC[O.sub.3] and HPMC K15M in the ratios of 1:1, 1:2, and 2:1 (w/w) on a dry solid basis as indicated in Table 2b.
Table IV.- Results of Kaiser-Meyer-Olkin (KMO) measure and Bartlett's test of sphericity.
Bartlett's test of sphericity showed the sample was suitable for factor analysis (p<0.001).
Verilerin aciklayici faktor analizi icin uygunlugu, Kaiser Meyer Olkin (KMO) katsayisi ve Barlett Sphericity testi ile incelenmistir.
Average area ([cm.sup.2]), roundness, maximum diameter (cm), minimum diameter (cm), sphericity, contour irregularity and perimeter (cm) of seeds from two Moringa oleifera Lam.
Sphericity was not violated for the main effect of question difficulty as there was only two levels.
"Our system will allow you to climb to a height of 30-40 km cheaper and safer [than spaceflights], but it will give you the opportunity to see the blackness of the cosmos, the sphericity of the spherical Earth and to be at a height where only one-hundredth of the atmosphere will remain," Efremov (https://hybridtechcar.com/2018/09/04/russian-engineers-launched-a-spacesuit-in-the-stratosphere/) concluded.
The giant open dune deposits that we are mining have important advantages relative to buried sand deposits, including less pedogenesis and thus fewer impurities, and thousands of additional years of mother nature's winnowing and sorting to enhance sphericity and thus quality."
When the correlations were verified with Bartlett's test of Sphericity for the biometric traits, the results were significant (P<0.01, Chi-square value 182.865) which was supportive for the rationality of the factor analysis of the data as indicated in Table-4.
The Bartlett's sphericity test was found to be significant (p<0.05), showing that the data set had multivariate normality (37,38).
Additionally, the following physical properties of the different hybrids were determined: apparent specific weight, actual specific weight, porosity, circularity and sphericity. Apparent specific weight ([rho]) was determined based on the relationship between weight and volume occupied by maize grains, whereas the actual specific weight ([[rho].sub.r]) was obtained according to Moreira et al.
