Uniform methods for estimating direct and indirect costs of AOM should be agreed upon to reliably compare the cost effectiveness of available and future pneumococcal vaccines against AOM.”
“The nonisothermal degradation process
BI-D1870 of Folnak (R) drug samples was investigated by simultaneous thermogravimetric and differential thermal analysis in the temperature range from an ambient one up to 810 degrees C. It was established that the degradation proceeds through the five degradation stages (designated as I, II, III, IV, and V), which include: the dehydration (I), the melting process of excipients (II), as well as the decomposition of folic acid (III), corn starch (IV), and saccharose (V), respectively. PHA-848125 solubility dmso It was established that the presented excipients show a different behavior from that of the pure materials. During degradation, all excipients increase their thermal stability, and some kind of solid solid and/or solid-gas interaction occurs. The kinetic parameters and reaction mechanism for the folic acid decomposition were established
using different calculation procedures. It was concluded that the folic acid decomposition mechanism cannot be explained by the simple reaction order (ROn) model (n=1) but with the complex reaction mechanism which includes the higher reaction orders (RO, n>1), with average value of < n >=1.91. The isothermal predictions of the third (III) degradation stage of Folnak (R) sample, at four different temperatures (T(iso)=180 degrees C, 200 degrees C, 220 degrees C, and 260 degrees C), were established. It was concluded that the shapes of the isothermal conversion curves at lower temperatures
(180-200 degrees C) were similar, whereas became more complex with further find more temperature increase due to the pterin and p-amino benzoic acid decomposition behavior, which brings the additional complexity in the overall folic acid decomposition process.”
“Relaxation processes in copolymers of vinylidene fluoride with hexafluoropropylene (93/7) were studied by means of a dielectric method. The initial extruded film was recrystallized by free heating to temperatures above the melting point and by subsequent cooling. This increased both the perfection of the crystal phase and the degree of crystallinity. The impact of recrystallization on both the relaxation times (tau’s) and the activation parameters of the local mobility (beta process) and micro-Brownian cooperative mobility in amorphous phase (alpha(a) process) was almost negligible, whereas the tau’s of the alpha(c) relaxation were an order of magnitude higher after recrystallization. Qualitatively, it was predicted by the soliton model for the alpha(c) relaxation. The recrystallization affected characteristics of the transition at the highest temperature (alpha) registered in the region of the melting of the crystals even more.
