Realizing The World Health Organization’S Constitutional Mission: Equitably And Everywhere, Sam Halabi, Lawrence Gostin

University of Chicago Legal Forum

COVID-19 revealed deeply embedded inequalities in countries’ capacity to respond to public health disasters. From 2020 to 2024, the content and scope of international health law expanded to address these deep inequities, including a new pandemic agreement and significant changes to the International Health Regulations (IHR). Recent moves by the Trump Administration leveled significant losses on this new global health law infrastructure. At the heart of this infrastructure is the World Health Organization (WHO)—the UN’s specialized agency, which for 77 years has led the world toward realizing the human right to the highest attainable standard of mental and physical health. …

Direct Solar-Energy Powered Hydrothermal Treatment To Promote Biomethane Production From Anaerobic Digestion Of Rice Processing Waste, Kainat Rahnuma

Student Theses and Dissertations

Hydrolysis is a slow and energy-intensive process and a rate-limiting step in anaerobic digestion (AD). This research investigates performance strategies for integrating hydrothermal treatment (HT) with AD. HT-AD systems were less economically viable than AD-only options because of the high energy consumption of HT. Therefore, we used solar energy to conduct HT via either solar cookers or solar panels. The HT method significantly improved digestion performance, reducing the lag phase from 60 to 24 h, and increasing overall yield. Hydrothermally treated rice, rice bran, and rice hulls produced 22,932 mL, 13,136 mL, and 1283 mL, respectively. However, untreated rice, rice …
