an algebraic construction for constant dimension subspace codes is called orbit code. it arises as the orbits under the action of a subgroup of the general linear group on subspaces in an ambient space. in particular orbit codes of a singer subgroup of the general linear group has investigated recently. in this paper, we consider the normalizer of a singer subgroup of the general linear group a...

Keeping the eye is impossible, functionality is lost and aesthetic requirements are high. What do we do? Which approach is right? This is the dilemma we face whenenucleation or evisceration are unavoidable. The patient loses a sensory organ with a very important function and, at the same time, is faced with a major aesthetic defect, leading to significant anxiety. The purpose of this article is...

BACKGROUND: Ocular prosthetics remains an important and actual task in the rehabilitation of patients with anophthalmos various origins.
 AIM: To increase effectiveness cosmetic at formation a primary and/or delayed supporting stump simultaneous reconstructive procedures on orbital bone structures.
 MATERIALS AND METHODS: A retrospective analysis subatrophy deformities walls was carri...

Several ocular and orbital disorders require surgical intervention that may result in ocular defects. The associated psychological effect of these defects on the patient requires immediate management and rehabilitation intervention by a team of specialists. The role of the maxillofacial prosthodontist in fabricating an ocular prosthesis with acceptable esthetics to restore facial symmetry and n...

Abstract In this paper, we study the generalized order- Jacobsthal sequences modulo for and the generalized order-k Jacobsthal-Padovan sequence modulo for . Also, we define the generalized order-k Jacobsthal orbit of a k-generator group for and the generalized order-k Jacobsthal-Padovan orbit a k-generator group for . Furthermore, we obtain the lengths of the periods of the generalized order-3 ...
