Enhancement of specular behavior in atom mirrors with quadrupole-active transitions
Alexandria Engineering Journal, 2023 Modern studies have confirmed the possibility of making atomic mirrors using quadrupole-active atomic transition evanescent waves. The reflection process has been shown to be enhanced to approach specular behavior in several ways.

Effects of electric quadrupole interactions with tunable atomic mirrors
Alexandria Engineering Journal, 2023 Recent studies have involved electric quadrupole effects in atoms interacting with the evanescent mode. This type of surface mode is usually produced by the total internal reflection in a dielectric-vacuum atz=0, and its intensity distribution is very ...

Generate localized optical vortices by quadrupole transition and twisted light
Journal of Taibah University for Science, 2021 We explain how quadrupole-active atomic interactions be able to be enhanced once the neutral atom interacts with an evanescent winding light modes.

Enhanced quadrupole effects for atoms in surface spiral beams with a thin dielectric waveguide
Alexandria Engineering Journal, 2022 Recently, some physical research has recognized the coupling of optical phase singularity light with quadrupole-active atomic transitions. We show that a Laguerre-Gaussian beam, when completely internally reflected at the dielectric/vacuum interface, can

Gastric Explosion While Using Electric Cautery During Gastrojejunostomy: A Case Report
Oman Medical Journal, 2023 Gastrointestinal gases become combustible when several gases reach a certain concentration. This occurs in situations where the gastrointestinal tract is obstructed for a certain amount of time.

Three Different Approaches (Hostile, Mythical, and Admiring) to Nasir Khusraw in the History of Persian Literature [PDF]
Matn/Pizhūhī-i Adabī, 2023 Nasir Khusraw is one of the great and influential figures in the history, culture, and literature of Iran. But because of his political and ideological activity in the dominant religion, some have sometimes deliberately ignored him, and beyond that, some

Active-quadrupole interaction of Bessel beams and their influence on atoms
Journal of Taibah University for Science, 2020 This paper explains how the optical quadrupole interaction between a two-level neutral atom and two counter-propagating non-diffracting Bessel beams can exhibit interesting rotational characteristics.

International Journal of Endocrinology, Volume 2019, Issue 1, 2019., 2019 Introduction. The blood irisin concentrations may be affected both by exercise and pregnancy. We aimed to determine acute responses in serum irisin after a single exercise session and relationships between exercise‐induced changes in this hormone and lipid profile in pregnancy. Material and Methods. It was an experimental study in 20 Caucasian women in

BioMed Research International, Volume 2017, Issue 1, 2017., 2017 Background. Both exercise and pregnancy influence serum irisin concentration. Aim. To determine how the interaction of pregnancy and exercise affects irisin level and whether various patterns of exercise adherence had different effect on irisin concentration. Methods. It was a one‐group pretest‐posttest study among 9 Caucasian nulliparous healthy women
