in this paper, we introduce and study the prime, strongly prime,semiprime and irreducible fuzzy bi-ideals of a semigroup. we characterize thosesemigroups for which each fuzzy bi-ideal is semiprime. we also characterizethose semigroups for which each fuzzy bi-ideal is strongly prime.

resistance literature is full of patriotism and liberalism. the resistance poet defends the aims of his hometown by his poetry weapon and applies his poem at his country’s political and social service. thus the resistance poetry contains a strong epic and national spirit. this kind of literature calls people for defending their grand ideals. tamim al-barghouti is a young palestinian famous poet...

We obtain strong coloring theorems at successors of singular cardinals from failures of certain instances of simultaneous reflection of stationary sets. Along the way, we establish new results in club-guessing and in the general theory of ideals.

In this paper, we introduce the concept of a new algebraic structure: independent UP-algebras (in short, IUP-algebras), which is UP-algebras. We also concepts IUP-subalgebras, IUP-filters, IUP-ideals, and strong IUP-ideals IUP-algebras investigate their properties relationships. Finally, discuss homomorphisms between study direct inverse images four special subsets.

Vibriosis is one of the major diseases leading to massive fish mortality. Probiotics may provide a potential alternative method protect from pathogens and promote balanced environment minimizing use antibiotics chemotherapy. The aims this study were (i) isolate purify marine spore-former strains Sardine shrimp intestine, (ii) screen for bacteria with probiotic properties, (iii) carry out their ...

In recent years research has recognised that notions of body image, body image ideals and body dissatisfaction develop much earlier than was once thought. Forty-seven children (25 male; 22 female) aged between 5 and 6 years were interviewed on three occasions over 12 months regarding their perceptions of body image. The interviews revealed strong negative perceptions of fatness. However, being ...

let $r$ be a commutative ring. the purpose of this article is to introduce a new class of ideals of r called weakly irreducible ideals. this class could be a generalization of the families quasi-primary ideals and strongly irreducible ideals. the relationships between the notions primary, quasi-primary, weakly irreducible, strongly irreducible and irreducible ideals, in different rings, has bee...
