Numerical investigation of the cold-formed I-beams bending strength with different web shapes

Fracture and Structural Integrity, 2021
The wide use of cold-formed sections (CFS) in the field of steel constructions, favored by the multiple advantages they offer (lightness, ease of installation, etc.), has led us to reflect on a new process for manufacture of metal beams allowing the ...

The institutional paradox of a substantivist conception of the economy in public policy: Insights from public procurement for solidarity economy in Ecuador

Annals of Public and Cooperative Economics, EarlyView.
Abstract Ecuador's 2008 Constitution advanced an ambitious substantive economic vision through Buen Vivir (Good Living), recognizing a plural economy which encompasses private, public and solidarity economy (SE) sectors. This paper aims to analyze public procurement programs in Ecuador, one of the flagship Buen Vivir policies for SE promotion.

Advances in Floating Solar Desalination Systems

Water and Environment Journal, EarlyView.
This review critically classifies floating solar desalination systems into five main categories and compares their thermal performance, productivity and technological limitations. Membrane‐based and multieffect systems showed the highest efficiencies, while traditional designs remain limited by heat losses and scaling.

Deep learning and computer vision for image‐based high‐throughput phenotyping of canning quality traits in dry beans

The Plant Phenome Journal, Volume 9, Issue 1, December 2026.
Abstract Canning color retention is a key quality trait in dry bean (Phaseolus vulgaris L.) breeding, influencing consumer acceptance and commercial value. Public breeding programs maintain canning quality as a selection trait of importance, but existing color evaluation methods such as visual rating are subjective, while instrument colorimetry is ...

Radical Healing in Three Marginalised South African Communities: Practices and Places of Healing

Journal of Community Psychology, Volume 54, Issue 5, July 2026.
ABSTRACT The ongoing system of coloniality, sustained through dehumanisation, racialised violence, oppression, war, and genocidal acts of violence, has left many from the Global South socially divided, economically depleted, wounded, materially impoverished, socially precarious and politically vulnerable.

Shear capacity evaluation and buckling mechanisms of composite I-girders with corrugated steel webs

Case Studies in Construction Materials
Corrugated steel webs provide high shear stability, transverse rigidity, and construction efficiency, motivating the development of steel-concrete composite I-girders in which the web is connected only to a concrete slab at the top.

Dielectric Barrier Discharge Plasma Deoxidation of Natively Oxide Layer of Copper Powders in a Fluidized Bed

Advanced Engineering Materials, Volume 28, Issue 12, 17 June 2026.
This paper presents a novel approach to reducing oxide layers on metal powders using low‐temperature hydrogen dielectric barrier discharge plasmas at atmospheric pressure. Unlike conventional hydrogen‐plasma reductions, the powders do not contact the plasma directly.

Shear Capacity of Singly and Doubly Webbed Corrugated Web Girder

Scientific Research Journal, 2006
A conventional plate girder involves the use of transverse intermediate stiffeners, especially in a slender web to avoid catastrophic failure associated with shear buckling of the web. In this study, a profiled web was used to replace the transversely stiffened web.

Coating Artificial Spider Silk Fiber with Magnetic FeCo: An Effective Strategy for Creating a Flexible Magneto‐Responsive Material

Advanced Functional Materials, Volume 36, Issue 48, 15 June 2026.
An original method is presented for producing artificial spider silk fibers with magnetic and magnetomechanical responsiveness, which consists in coating them with a nanometer‐thick layer of FeCo alloy by sputtering deposition. The challenge of combining organic materials and inorganic magnetic nanostructures is addressed, thus taking a step forward ...
