In this work the isothermal transition from bubbling to jetting regime in a bottom blown Peirce-Smith copper converter is numerically studied, varying the air jet injection velocity from 5 to 100 m s -1 . Large Eddy Simulation turbulence model is employed in the computer simulations to obtain transient, rather than averaged, phase distributions. For low injection velocities the bubbling regime ...

The principle of trichotomy from the American philosopher Charles S. Peirce can be used to categorize processes into the triad of transactional, informational, and relational. The usefulness of these categories is explicated by a comparison with structuration theory and control theory, and elaborated with a consideration of democracy in a knowledge economy. These three example applications of t...

This study aims to achieve a semiotic understanding of collective memory of the Iran-Iraq war. For this purpose, samples of images in virtual social networks shared in response to the news of discovery and return of the bodies of more than 175 divers have been analyzed. Visual signs in photographs, cartoons, graphic designs, prints, paintings and posters, in methods of historical pictures and f...

ion comes from the Latin abstractio (detachment, division, retention), introduced by the Roman philosopher and theologian Boethius when translating Aristotle’s term aphairesis. Since the relevant to us meaning of the term abstraction has to do with the process of forming a general mental image of an object—note the root Form—we are entirely justified in interpreting this meaning as directly rel...

Peirce developed an analysis of reality that defined reality – all forms of reality, whether chemical, biological or social as existing in Signs. A sign is a spatiotemporal reality, material or conceptual, that exists in relations with other signs, as in “I use the word “Sign” in the widest sense for any medium for the communication or extension of a From (or feature). Being medium, it is deter...

C. S. Lewis javnosti je manje poznat po svom znanstvenom radu, a više ciklusu Kronike iz Narnije. Za života je, između ostalog, napisao dva djela posvećena srednjem vijeku: Alegorija ljubavi i Odbačena slika. U ovom radu autorice će analizirati stav književnih kritičara spram spomenutih Lewisovih djela. Razvidno da se istraživala shvaćala kao znanstveno djelo o srednjemu vijeku kojem kritika ug...

Contemporary pragmatists, especially those who follow Richard Rorty’s lead, have contested the philosophical paradigm they have referred to as ‘representationalism’: the idea that our claims or beliefs describe or are ‘about’ the world. These ‘new pragmatists’ have often been seen to be in an antagonistic relationship with their antecedents, the pragmatists of the turn of the 20th century: thes...
