U.S. Food Aid: It’s Not Your Parents’ Program Any More! [PDF]
Much has changed in the 50 years since modern food aid began with the enactment of U.S. Public Law 480 in 1954. Yet contemporary policy debates often become derailed by failures to appreciate the significant changes that have already occurred. This paper

ABSTRACT This study successfully prepared magnetic iron/cobalt codoped biochar catalyst (CFSBC) using a one‐step calcination method. The morphology and structure of the material were systematically characterized using SEM, XRD, FTIR, TEM, BET, Raman, VSM, and XPS techniques. The effects of key parameters such as catalyst dosage, peroxymonosulfate (PMS)

ABSTRACT Greenhouse gas (GHG) emissions have emerged as one of the most critical drivers of climate change; this is primarily due to high concentrations and long atmospheric life of carbon dioxide (CO2). For a significant amount of time, various biological processes such as microalgal cultivation, cyanobacterial systems, photosynthetic microorganisms ...

ABSTRACT Water is a fundamental necessity for our existence, but its rapid contamination is causing devastating effects on the environment and health of living species worldwide. Adsorptive removal of pollutants is one of the popular water treatment techniques because of its simplicity, affordability, and the broad range of available adsorbents.

ABSTRACT Bamboo charcoal–based extruded activated carbons were prepared via molding, pre‐oxidation, carbonization, and steam activation, with coal tar, phenolic resin, and their mixtures employed as binders based on practical availability and technical feasibility. This study focused on the regulatory effects of binders on the mechanical properties and

"Exaggerated Death of Distance: Revisiting Distance Effects on Regional Price Dispersions" [PDF]
This paper empirically establishes the significant roles of transport costs in price dispersions across regions. We identify and estimate the iceberg-type distance-elastic transport costs as a parameter of a structural model of cross-regional price ...
