The following concepts shall be required in the sequel: Definition 1.1 [5, 27]. A uniform space (X,Φ) is a nonempty set X equipped with a nonempty family Φ of subsets of X ×X satisfying the following properties: (i) if U is in Φ, then U contains the diagonal {(x, x) |x ∈ X}; (ii) if U is in Φ and V is a subset of X ×X which contains U, then V is in Φ; (iii) if U and V are in Φ, then U ∩ V is in...

Keratoconus is a disease characterized by progressive thinning, bulging, and distortion of the cornea. Advanced cases usually present with loss of vision due to high irregular astigmatism. A majority of these cases require surgical intervention. This review provides an update on the current treatment modalities of corneal surgery available for the management of advanced corneal ectasias.

In this work, we attempt to investigate the connection between various types of ideals (for examples (m,n)-ideal, bi-ideal, interior-ideal, quasi-ideal, prime-ideal and maximal-ideal) of an ordered semigroup (S, ·,≤) and the corresponding, hyperideals of its EL-hyperstructure (S, ∗) (if exists). Moreover, we construct the class of EL-Γ-semihypergroup, associated to a partially-ordered Γsemigroup.

The ancestral relationship between philosophy and theology will be worked here not abstractly but based on some of its historic achievements. From the diversity theological areas discourse trends—especially in last century—the article proposes to establish a this contemporary philosophical proposals.
