let $r$ be a commutative ring with identity. an ideal $i$ of a ring $r$is called an annihilating ideal if there exists $rin rsetminus {0}$ such that $ir=(0)$ and an ideal $i$ of$r$ is called an essential ideal if $i$ has non-zero intersectionwith every other non-zero ideal of $r$. thesum-annihilating essential ideal graph of $r$, denoted by $mathcal{ae}_r$, isa graph whose vertex set is the set...

in this note we consider the notion of intuitionistic fuzzy (weak) dual hyper k-ideals and obtain related results. then we classify this notion according to level sets. after that we determine the relationships between intuitionistic fuzzy (weak) dual hyper k-ideals and intuitionistic fuzzy (weak) hyper k-ideals. finally, we define the notion of the product of two intuitionistic fuzzy (weak) du...

In the field of cell biology it is usual to characterize cellular components obtained after different separative procedures by enzyme markers characteristic for a particular cell constituent. In the field of virology such procedures are generally not in use for the characterization of virus preparations. More often the labeling of cell proteins is employed when a differentiation between virus-s...

To separate the MM and MB creatine kinase (EC 2.7.3.2) isoenzymes in small plasma samples, we developed a simple, rapid ion-exchange batch-adsorption procedure with "DEAE Glycophase" glass beads (Corning). All separative steps are performed in a single test tube and can be completed within a few minutes. Results of measurements of isoenzymes in plasma samples from patients with acute myocardial...

In today’s highly complex software systems it’s often impossible to enforce and evaluate dependability requirements unless they are taken into account from the beginning of the development process. Retrofitting it into the system at the code level is not a satisfactory way of solving this problem. Dependability requirements cause transformations to be made to a software system’s architecture on...

in this paper, various elementary properties of vague rings are obtained. furthermore, the concepts of vague subring, vague ideal, vague prime ideal and vague maximal ideal are introduced, and the validity of some relevant classical results in these settings are investigated.

The separative logic is not educational. essay reviews the historical events that have generated an undervaluation of vocational training pathways compared to education pathways. This "minority" perception and legislation stems from a separation with many faces which, taken all together, etiological spirit historical-ordinamental contextualization, explain "untenable" inferiority education: peo...
