This report is a rst attempt of formalizing the diagonalization proof technique. We give a strategy how to systematically construct diagonalization proofs: (i) nding an indexing relation, (ii) constructing a diagonal element, and (iii) making the implicit contradiction of the diagonal element explicit. We suggest a declarative representation of the strategy and describe how it can be realized i...

The last few years have seen an opening up of what is considered to be the legitimate terrain of international relations (IR). This move is, for the most part, extremely welcome. Yet, the multiple theoretical and empirical openings in IR since the end of the Cold War have failed to elucidate many of the puzzles, questions and problems posed by the contemporary conjuncture. There are a number of...

The paper presents an analysis of relations describing entropy generation in a condenser of a steam unit. Connections between entropy generation, condenser ratio, and heat exchanger effectiveness, as well as relations implied by them are shown. Theoretical considerations allowed to determine limits of individual parameters which describe the condenser operation. Various relations for average te...

Let Θ be an arbitrary variety of algebras and H an algebra in Θ. Along with algebraic geometry in Θ over the distinguished algebra H, a logical geometry in Θ over H is considered. This insight leads to a system of notions and stimulates a number of new problems. Some logical invariants of algebras H ∈ Θ are introduced and logical relations between different H1 and H2 in Θ are analyzed. The pape...

The two main types of law are legislation and precedents. Both types have a corresponding reasoning pattern determining legal consequences: legislation can be applied and precedents followed. The separate modelling of these two reasoning patterns using logical techniques has recently seen considerable progress. About the logical links between the two less is known, although progress has already...

Physician assistants (PAs) have been used for decades in the Canadian military. Now, PAs are being introduced in various clinical settings to provide patient care for the general population. This article reviews major developments in the PA profession across Canada over the last decade. Nearly 541 PAs are employed in Canada or work for a Canadian agency. Growing evidence demonstrates the positi...
