Breaking from the past? Environmental narratives, logics of power, and the (re)production of food insecurity in South Sudan.

Skyrocketing commodity prices and conflict-induced mass hunger in recent years have resuscitated discussions about why famines frequently reoccur in specific spaces of vulnerability. Intervention efforts still too often isolate food (in)security from its interwovenness in the political economy of water and energy and from the role of ideas in forging these interconnections across long time periods. Using (South) Sudanese history to rethink the causes of recurrent food insecurity, we underscore the need to analyse how political elites imagine the role of the water-energy-food nexus and associated environmental narratives in consolidating power.

A comprehensive assessment of a prototype high ratio antiscatter grid in interventional cardiology using experimental measurements and Monte Carlo simulations.

. To assess the performance of a new antiscatter grid design in interventional cardiology for image quality improvement and dose reduction using experimental measurements and Monte Carlo (MC) simulation.Experimental measurements were performed on an angiography system, using a multi-layered tissue simulating composite phantom made from of poly(methyl methacrylate), aluminium and expanded polystyrene (2/0.

Should Ultrasound-Guided High Frequency Focused Ultrasound Be Considered as an Alternative Non-Surgical Treatment of Uterine Fibroids in Non-Asiatic Countries? An Opinion Paper.

Minimally invasive interventions for myomata treatment have gained acceptance due to the possibility of preserving fertility with reduced trauma induced by laparotomy as way of entrance. There are insufficient data regarding outcomes of high intensity focused ultrasound (HIFU) in non-Asiatic women. Therefore, we revised the available evidence to present an expert opinion that could support physicians, patients and policy-makers for considering this approach in other populations.

Production cross-section measurements of proton-induced reactions on natural tantalum in the 0.3 GeV-1.7 GeV energy range.

This work reports the production cross-section data for seventy-one radionuclides produced by 0.3 GeV-1.7 GeV protons impinging on thin tantalum targets.
