Effect of the reaction mixture on the structure and permeability of macroporous SiO[2], obtained by sol gel by method

In this paper, a number of porous silicone monoliths were synthesized under various conditions and their composition, structure, permeability coefficients k, and porosity were studied. The effect of the introduction of ethyl alcohol in the reaction mixture on the properties of the obtained silica was revealed

Variables affecting the probability of complete fusion of the medial clavicular epiphysis

In this study, we have combined data on clavicle fusion from different studies and applied a binomial logistic regression analysis. As such, we aimed to assess whether or not variables such as sex, socioeconomic status, and ethnicity influence the probability of having mature, i.e., completely fused clavicles at a given age. We further explored whether the method of clavicle examination, i.e., diagnosis from either a dry bone specimen, an examination of X-rays, or an examination of computed tomography scans, affects the probability of being diagnosed with mature clavicles. It appeared that only ethnicity did not significantly affect this probability. Finally, we illustrated how the logit model may be used to predict the probability of being diagnosed with mature clavicles
