“…During the process, it was also possible to analyze that even with different routes, at the end of the process the decomposition of all materials had approximate the same results, being understood that when different substrates are involved, different organisms are stimulated and can develop in different forms and concentrations. Thus, an organism with faster kinetics can compete with another organism of slower kinetics, even in smaller quantity, thus obtaining equivalent results at the end of the process [18][19][20][21].…”

“…However, even with variations, studies show the efficient reduction of tons of OM to humus in all processes hitherto applied, which can be returned to the environment in the form of natural fertilizer. No citations were found about the use of composting in the processing of mineral raw materials, making this pioneering work in this type of application [18][19][20][21].…”

The process of beneficiation of a peaty ceramic raw material extracted from the Poços de Caldas region, MG, through the composting method to reduce organic matter (OM) was analyzed. The raw materials used in separate piles were divided, keeping one of the samples pure (TP) and adding bovine wastes in the second (TB). The process lasted 6 months and, at the end of each month, the amount of MO was analyzed by the Walkley-Black method. Results of maximum degradation of 56%±6% of OM in the TB and 47%±5% of OM in the TP were obtained. The ceramic characterization of the processed raw material was then carried out. It has been proved that the proposed method is efficient for the decrease of OM in the ceramic raw material. Regarding the composting product, the results were positive, showing that this material can be used in ceramic applications.

“…Another method, considered to be the most efficient for the calculation of the LVV is Simpson's rule (Figure 1), where it is considered that the LV has a circular geometry in the transversal cuts, that is, in the perpendicular cuts to its long axis [3,[12][13][14][15][16]. This rule calculates the sum of the volumes of the N parallel slices from the apex to the base of the LV, where r i is the radius of each one, and L is the measurement of this chamber'a long axis, as described by Equation (2).…”

The main objective of this article is to determine the existing linear correlation between the real left ventricular volume (RV) from the heart of bovines and the volumes obtained by Teichholz's mathematical model and the volume of the truncated prolate spheroid (TPS) to identify which model has a higher proximity to the RV. For that, ten silicon rubber molds of the left ventricle (LV) were manufactured, and their real volumes were obtained through Archimedes' principle, and their linear dimensions were also obtained. These dimensions were used to feed Teichholz's and the TPS models. It was verified that, for ventricles of lower volume, the models showed relatively close results, and Teichholz's model was the most accurate one. The TPS method shows a grave accuracy mistake for higher volume ventricles. Besides, both methods showed strong linear correlations with the RV, and both with high significance.
