Assessment of hepatic volume ex vivo by the formulas of the ultrasound volumetry
The article focuses on determination of the liver volume which is an urgent task for clinical medicine. It is directly connected to the need for an objective quantitative assessment of organ size. The complexity of calculating the volume is due to an irregular geometric shape of the organ, which can not be approximated to an ellipse or any other geometric figure. The aim of the study is to ex vivo evaluate the possibilities of measuring the volume of the liver based on the linear dimensions of the organ according ...
J. N. Tetens’s ‘transcendental philosophy’ as a basic science¬ and criti¬cal propaedeutics to metaphysics
... J. N. Tetens sets out to justify the possibility and necessity of metaphysics as a general speculative science. His primary objective is to defend metaphysics against the opponents, the most serious of which, in Tetens’s opinion, is D. Hume. In this ... ... criticism of systemic knowledge in general and metaphysics in particular. In the argument between the advocates of the Leibniz-Wolff geometric philosophy and their opponents — enlighteners-eclecticists and pietists, Tetens manages to take a neutral position ...
Kant and new mathematics 100 years later
Cassirer’s critique of Russell’s philosophy of mathematics and the Neo-Kantian philosophy of science and mathematics as a whole is of special relevance in the context of modern mathematics and mathematical physics. The fact that the modern standard axiomatic architecture of mathematical theories does not take into account the object-based character of mathematical knowledge, which was stressed after Kant by Cassirer, complicates the application of new mathematical theories in natural sciences and...
A transcendental analysis of mathematics: The constructive nature of mathematics
... of schematism, Kant develops an original theory of abstraction: Kant’s schemes serve as a means to construct mathematical objects, as an “action of pure thought" [CPR, B 81]. A ‘constructive’ understanding of mathematical acts going back ... ... (Wittgenstein; cf. mathematical structuralism). In his theory, Kant distinguishes between two types of constructing — ostensive (geometric) and symbolic (algebraic). The paper analyses these types and shows that modern mathematical structures are a combination ...
