Enabling Sustainability in Local Food Supply Chains: A Life Cycle Assessment‐Based Approach

open access: yesSustainable Development, EarlyView.
ABSTRACT In response to escalating environmental and food security challenges, this study explores how Local Food Systems (LFS) and Short Food Supply Chains (SFSCs) can be redesigned to support sustainability goals. Drawing on a case study of a microalgae‐based food producer, the research applies a Resource Nexus Approach combined with Life Cycle ...

A Technique for Retrieving the Exospheric Number Density Distribution from Pickup Ion Ring Distributions

open access: yesThe Planetary Science Journal
Ion pickup by the solar wind is ubiquitous in space plasma. Because pickup ions are originally produced by ionization of an exospheric neutral atmosphere, their measurements contain information on the exospheric neutral abundance.

A Critical Review on Nitrogen Control in the Scrap‐Based Electric Arc Furnace Steelmaking Route to Produce Low‐Nitrogen Steels

open access: yessteel research international, EarlyView.
In primary electric arc furnace (EAF) steelmaking, carbon boiling removes nitrogen from liquid steel and sustains slag foaming. In 100% scrap‐ or hydrogen direct reduced iron (HDRI)‐based EAF steelmaking, carbon boiling is absent; therefore, carbonaceous material and oxygen injection into the slag is needed to maintain foaming and avoid nitrogen ...

Optical stochastic cooling for RHIC using optical parametric amplification

open access: yesPhysical Review Special Topics. Accelerators and Beams, 2004
We propose using an optical parametric amplifier, with a ∼12   μm wavelength, for optical-stochastic cooling of ^{79}Au ions in the Relativistic Heavy Ion Collider.
