T here have been numerous dialogues in nursing about its mission and definition, but a refinement of existing definitions has yet to be offered. This article is written with the goal of maintaining a vigorous discourse. The phenomena of concern to the discipline of nursing that have been described by various theorists, and generally accepted by members of the discipline, are health, person, env...

A new definition of Embedded Push-Down Automata is provided. We prove this new definition preserves the equivalence with tree adjoining languages and we provide a tabulation framework to execute any automaton in polynomial time with respect to the length of the input string.

forbidding the redefinition of attribute types, inverting the routine argument redefinition rule to observe contravariance (redefined arguments should have more general types), judging type compatibility between parameterised types after replacing the type parameters and introducing an explicit type attribute scheme to handle Eiffel's anchored types. Contravariance is a counterintuitive finding...

Gene-specific expansion of the genetic code allows for UGA codons to specify the amino acid selenocysteine (Sec). A striking example of UGA redefinition occurs during translation of the mRNA coding for the selenium transport protein, selenoprotein P (SELENOP), which in vertebrates may contain up to 22 in-frame UGA codons. Sec incorporation at the first and downstream UGA codons occurs with vari...

Although the inheritance mechanism is one of the key points for the extendibility and reusability aspects of object-oriented (OO) systems, its current use has illustrated that the introduction of conceptual inconsistencies is possible in a class hierarchy. This paper discusses the issues involved in measuring aspects of redefinition of methods in an OO model. The work is intended to raise the p...

Klebelsbergite is verified as a valid mineral species, in museum specimens from the type locality, Baia Sprie (Felscib6nya), Rumania. Klebelsbergite occurs as pale yellow to orange-yellow crystals radially grown on stibnite. Wet-chemical analysis of synthetic klebelsbergite, supported by electron microprobe analyses of natural material, gives Sb 71.78, S 4.65, }{2O 2.69, O 20.88Vo (by di-fferen...

The circumscription of bacterial species is a complex task. So far, DNA-DNA hybridization (DDH), 16S rRNA gene sequencing, and multiocus sequence typing analysis (MLSA) are currently the preferred techniques for their genetic determination. However, the average nucleotide identity (ANI) analysis of conserved and shared genes between two bacterial strains based on the pair-wise genome comparison...

A case is reported which supports the principle that ACTH precursors best characterise so-called ectopic ACTH-syndrome, which should therefore more accurately be referred to as ectopic ACTH-precursor syndrome.
