Experimental and Numerical Study on Enhancing the Performance of a Stepped Solar Still Using Porous Sponge Materials

open access: yesEnergy Science &Engineering, EarlyView.
Three designs were built and tested: a single‐slope still, a six‐stepped still, and a six‐stepped still with 5 mm sponge sheets. The novelty lies in fixing porous sponge sheets to the vertical faces of the steps. Yield of freshwater and instantaneous efficiency were determined in various combinations, that is, base, stepped, and stepped‐cum‐sponge ...

Leveraging Atomic Disorder to Modulate Hydrogen Storage Thermodynamics in Intermetallics

open access: yesInterdisciplinary Materials, EarlyView.
This work introduces atomic disorder into TiFe‐based intermetallics through multi‐element substitution to tune hydrogen storage properties. A series of B2‐structured, compositionally complex intermetallics are synthesized and evaluated, revealing that increased atomic disorder enhances hydride stability.

Wild Animal Suffering Is Not Intractable: A Precautionary Approach to Compassionate Intervention

open access: yesJournal of Applied Philosophy, EarlyView.
ABSTRACT Wild animals suffer due to human activity, yet natural factors contribute far more significantly to their suffering. In light of this, some propose that we have a pro tanto obligation to intervene in ecosystems to improve wild animal welfare.

Holocene palaeoenvironmental reconstruction of sea level, coastal and vegetation changes along the southern Solway Firth, United Kingdom

open access: yesJournal of Quaternary Science, EarlyView.
Abstract Holocene relative sea level (RSL) changes were reconstructed from four sites along the less‐studied southern Solway Firth. A multiproxy approach, including lithostratigraphical and biostratigraphical analyses, combined with radiocarbon dating, produced ten sea level index points (SLIPs).

Special L-values of Drinfeld modules

open access: yes, 2011
We state and prove a formula for a certain value of the Goss L-function of a Drinfeld module. This gives characteristic-p-valued function field analogues of the class number formula and of the Birch and Swinnerton-Dyer conjecture.

Atypical Wounds in Chronic Graft‐Versus‐Host Disease and Peripheral Arterial Disease Caused by Tyrosine Kinase Inhibitors

open access: yesJEADV Clinical Practice, EarlyView.
ABSTRACT The term “atypical wounds” primarily refers to lesions with immunological or cancerous etiologies. However, these wounds can also be drug‐induced. We report about a 32‐year‐old man with a 6‐year history of chronic myelogenous leukemia (CML) and chronic graft‐versus‐host disease (cGvHD) following an HLA‐compatible allogeneic stem cell ...
