Body Image Perceptions and Body Image Dissatisfaction among Medical Students in Oman.

Objectives: This study aimed to examine body image perceptions and body image dissatisfaction and their relationship with body mass index (BMI) among medical students in Oman.

Methods: This cross-sectional study was conducted among students of the College of Medicine and Health Sciences, National University of Science and Technology, Sohar, Oman, between September and December 2019. The data (including self-reported weight and height) were collected through a questionnaire-based survey.

Design and development of a multi-functional bi-anisotropic metasurface with ultra-wide out of band transmission.

This paper presents a multi-functional bi-anisotropic metasurface having ultra-wide out of band transmission characteristics. The proposed metasurface is comprised of 90° rotated T-shaped configuration yielding greater than or equal to 50% out-of-band transmission from above L- to X-band. Moreover, this metasurface achieves a maximum of 99% out-of-band transmission at lower frequency bands (i.

A multifunctional ultrathin flexible bianisotropic metasurface with miniaturized cell size.

In this paper, a flexible bianisotropic metasurface possessing omega-type coupling is presented. The designed metasurface behaves differently when excited from either forward (port 1) or back (port 2) sides. It provides an absorption of 99.

Postoperative range of motion and stability after anterior cruciate ligament reconstruction using quadrupled hamstring autograft.

Background: The incidence of anterior cruciate ligament (ACL) tear is increasing, especially in young active adults. Various surgical options like bone-patellar tendon-bone graft and hamstring autograft have been the focus of evaluation and comparison in various aspects, each having specific advantages and demerits. We are increasingly using and analysing quadrupled hamstring autograft for ACL reconstruction.
