Pet birds, being previously unexposed to the many dangers of our industrial world, are prime candidates for the ingestion/inhalation of toxins. What follows is a highlight of the most common toxins found in our homes. These will include "acute" fast acting fatal toxins and the "chronic" more long term, but still deadly types of toxins. REMEMBER: WHEN CONSIDERING IF A PRODUCT MIGHT BE TOXIC OR N...

In diesem Beitrag wird der Zusammenhang zwischen Code-Qualität und UMLModellen in einem Software-Entwicklungsprozess in der Informatik-Ausbildung vorgestellt. Es wird untersucht, welche der im Code sichtbar werdenden Mängel bereits im Modell erkannt werden können. Werkzeuge zur statischen Code-Analyse und Refactoring-Techniken unterstützen die Studierenden beim Entdecken und Beseitigen der Qual...

A ring [Formula: see text] is said to be clean if each element of can written as the sum a unit and an idempotent. weakly either or difference idempotent, feebly every text], where are orthogonal idempotents. Clearly, rings both them clean. In recent paper (J. Algebra Appl. 17 (2018) 1850111 (5 pp.)), McGoven characterized when group clean, distinct primes. this paper, we consider more general ...

let r be an associative ring with unity. an element a in r is said to be r-clean if a = e+r, where e is an idempotent and r is a regular (von neumann) element in r. if every element of r is r-clean, then r is called an r-clean ring. in this paper, we prove that the concepts of clean ring and r-clean ring are equivalent for abelian rings. further we prove that if 0 and 1 are the only idempotents...

in this paper, we introduce the new notion of strongly j-clean rings associatedwith polynomial identity g(x) = 0, as a generalization of strongly j-clean rings. we denotestrongly j-clean rings associated with polynomial identity g(x) = 0 by strongly g(x)-j-cleanrings. next, we investigate some properties of strongly g(x)-j-clean.
