Lateral Earth Pressure at Rest and Shear Modulus Measurements on Hanford Sludge Simulants
This report describes the equipment, techniques, and results of lateral earth pressure at rest and shear modulus measurements on kaolin clay as well as two chemical sludge simulants. The testing was performed in support of the problem of hydrogen gas retention and release encountered in the double- shell tanks (DSTs) at the Hanford Site near Richland, Washington. Wastes from single-shell tanks (SSTs) are being transferred to double-shell tanks (DSTs) for safety reasons (some SSTs are leaking or are in danger of leaking), but the available DST space is limited

THE SCOPE AND IMPLICATIONS OF MORALS NOT KNOWLEDGE
I greatly appreciate the opportunity provided by the editor of Zygon to further develop the ideas in my book Morals Not Knowledge: Recasting the Contemporary U.S. Conflict between Religion and Science in conversation with four critical commentaries. It is an honor to have one's work focused upon so intently, and I greatly appreciate the time and effort of the critics. The book was quite intentionally written as a provocation, an attempt at agenda setting, and as a call for changing the thinking of the entire religion and science academic community. In my previous writings I have kept close to the data, allowing myself at best mid-level conclusions, but this book is a foray into the abstraction and inevitable lack of precision required for high-level generalization. I hope that it continues to be generative of debate

The Antifungal Pipeline: Fosmanogepix, Ibrexafungerp, Olorofim, Opelconazole, and Rezafungin.
The epidemiology of invasive fungal infections is changing, with new populations at risk and the emergence of resistance caused by the selective pressure from increased usage of antifungal agents in prophylaxis, empiric therapy, and agriculture. Limited antifungal therapeutic options are further challenged by drug-drug interactions, toxicity, and constraints in administration routes. Despite the need for more antifungal drug options, no new classes of antifungal drugs have become available over the last 2 decades, and only one single new agent from a known antifungal class has been approved in the last decade. Nevertheless, there is hope on the horizon, with a number of new antifungal classes in late-stage clinical development. In this review, we describe the mechanisms of drug resistance employed by fungi and extensively discuss the most promising drugs in development, including fosmanogepix (a novel Gwt1 enzyme inhibitor), ibrexafungerp (a first-in-class triterpenoid), olorofim (a novel dihyroorotate dehydrogenase enzyme inhibitor), opelconazole (a novel triazole optimized for inhalation), and rezafungin (an echinocandin designed to be dosed once weekly). We focus on the mechanism of action and pharmacokinetics, as well as the spectrum of activity and stages of clinical development. We also highlight the potential future role of these drugs and unmet needs
