Experimental and analytical study on axial behaviour of square corrugated concrete filled single and double skin tube stub columns.

Concrete-filled double-skin steel tubular (CFDST) columns have become widely utilized in building construction and bridges, thanks to their exceptional structural capabilities. Therefore, this study investigates the axial compressive behavior of square CFDST columns. The study aims to explore the influence of external and internal plate shapes (flat or corrugated plates) and different widths of internal steel tubes on the axial compressive behavior.

Effects of Enterobacter cloacae extract, selenium nanoparticles and methyl jasmonate on shoot liquid cultures of Sarcocornia fruticosa under salinity stress.

Background: The in vitro propagation of halophytes is innovative perspective for sustainable agriculture, conservation of natural plants and essential raw materials for industry due to increasing soil salinization and decreasing freshwater availability. Sarcocornia fruticosa, a halophytic plant, may hold promise for biosaline production systems and achieve bioactive products. Understanding the salt tolerance mechanisms of halophytes through elicitors can enhance the production of secondary metabolites, such as phenolics and flavonoids, under saline environment.

A Comparative study between the efficacy of combined Intense Pulsed Light plus high-intensity focussed ultrasound in the treatment of atrophic and icepick scars.

Objective: To investigate the efficiency of high-intensity focussed ultrasound with intense pulsed light in the treatment of atrophic and icepick acne scars.

Methods: The interventional study was conducted between November 2021 and April 2022 at the Postgraduate Medical Physics Laboratory, Mustansiriyah University, Baghdad, Iraq, and comprised patients with atrophic scars in group A and acne scars in group B. They were treated first with intense pulsed light and then with high-intensity focussed ultrasound.

The efficacy of combined Intense pulsed light plus high-intensity focussed ultrasound with two different powers in the treatment of atrophic and Icepick acne scars.

Objective: To determine the clinical efficacy and suitable power of high-intensity focussed ultrasound combined with intense pulsed light to treat acne scarring.

Methods: The prospective study was conducted at the College of Medicine, Mustansiriyah University, Baghdad, Iraq, from September 2020 to March 2021, and comprised patients of either gender with atrophic or icepick scars. They were divided into atrophic scar group A and icepick scar group B.
