Linear Antenna Array Sectorized Beam Scanning Approaches Using Element Position Perturbation in the Azimuth Plane.

In this paper, two sector beam scanning approaches (BSAs) based on element position perturbations (EPPs) in the azimuth plane are introduced. In EPP-BSA, the elements' excitations are kept constant and the elements' positions in the direction normal to the array line are changed according to a predetermined EPP pattern. The magnitude and repetition rate of the selected EPP pattern determines the steering angle of the main beam.

Prophylactic vaginal dinoprostone administration six hours prior to copper-T380A intrauterine device insertion in nulliparous women: A randomized controlled trial.

Objective: To determine the effectiveness of 3 mg vaginal dinoprostone administered six hours prior to copper intrauterine device (IUD) insertion compared to placebo in increasing ease of insertion and reducing insertion pain among nulliparous women.

Study Design: This was a single-center double-blinded randomized controlled trial (RCT). We randomly divided the two hundred nulliparous women requesting a copper T380A IUD to receive 3 mg vaginal dinoprostone or placebo six hours before IUD insertion.

Perioperative nonhormonal pharmacological interventions for bleeding reduction during open and minimally invasive myomectomy: a systematic review and network meta-analysis.

Objective: To synthesize evidence on the most effective pharmacological interventions for bleeding reduction during open and minimally invasive myomectomy.

Design: Systematic review and network meta-analysis of randomized controlled trials (RCTs).

Setting: Not applicable.

The Effect of Zumba Exercise on Reducing Menstrual Pain in Young Women with Primary Dysmenorrhea: A Randomized Controlled Trial.

Study Objective: To study the effectiveness of performing Zumba exercise on the severity and duration of pain in patients with primary dysmenorrhea.

Design: Randomized controlled trial.

Setting: Cairo University gynecology Hospital and Bahgat gym and fitness center.

Evaluating different pain lowering medications during intrauterine device insertion: a systematic review and network meta-analysis.

Objective: To synthesize the evidence on the most effective medications for the relief of intrauterine device (IUD) insertion-related pain.

Design: Systematic review and network meta-analysis of randomized controlled trials (RCTs).

Setting: Not applicable.
