Melanoma and Other Melanistic Lesions in Brown Bullhead Ameiurus nebulosus From Waterbodies in the Northeastern United States and Canada: Identification of Risk Factors

open access: yesJournal of Fish Diseases, EarlyView.
ABSTRACT Melanistic lesions, including non‐raised black areas due to proliferations of melanocytes and melanomacrophages in the dermis and epidermis, as well as raised black areas consistent with melanoma, are described in brown bullhead (BBH) Ameiurus nebulosus from three water bodies in the northeastern United States and Quebec, Canada.

A New Comprehensive Model to Simulate and Optimize Fluid Flow in Complex Well‐Formation System for In Situ Leaching Uranium

open access: yesEnergy Science & Engineering
In situ leaching (ISL) is an important method for green and efficient development of sandstone‐type uranium ore. It achieves ISL of uranium through the deployment of injection and extraction vertical well patterns.

The Origins of Ploem's Filter Cube: A Pandora's Box

open access: yesJournal of Microscopy, EarlyView.
Abstract Ploem's filter cube, central to modern epifluorescence microscopy, integrates three matched optical components: an excitation filter, an emission filter, and a dichroic mirror. Together, these elements enable the separation of excitation and emission light paths, producing high‐contrast fluorescence images.

Extraction of uranium(VI) with binary mixture of LIX 984 and naphthenic acid

open access: yes, 1998
Extraction studies of uranium(VI) with LIX 984 (HX) (an equivolume mixture of LIX 84 and LIX 860 in kerosene having a resulting mixture of 5-dodecyl salicylaldoxime and 3-nonyl acetophenone oxime in kerosene) and its binary mixture with naphthenic acid ...

Absorbents for Uranium Extraction From Seawater

open access: yes
Seawater contains approximately 4.5 billion tons of dissolved uranium, making it a significant potential source of nuclear fuel. However, the low uranium concentration, interference from competing ions, and the complex marine environment pose major ...

Geochemical investigation of impactites from the Boltysh impact structure and possible relationship to early Danian sediments from the Umbria–Marche Basin, Italy

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Within the Danian Scaglia Rossa Formation appears a regionally correlatable horizon cutting across multiple sections and outcrops within the Umbria–Marche Basin of NE Italy, where it is intercalated with uniform pelagic carbonate successions. This horizon is called “ALE layer” and has tentatively been interpreted as a fine‐grained volcanic ash.

Alternative approaches to dryland reclamation enhance vegetation cover and soil stability at a former uranium mine

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Conventional reclamation methods to recover dryland ecosystems after mineral extraction often have low success. Alternative reclamation techniques may help overcome the many challenges to establishing persistent native vegetation and stable soils.

Extraction of Uranium by a Pyrazole-Based Porous Organic Polymer

open access: yes
In this work, we report a pyrazole-based porous organic polymer (namely, ECUT-POP-2) for extraction of uranium. ECUT-POP-2 affords a high uranium extraction capacity of up to 1851 mg/g, excellent selectivity, and good reusability, suggesting its superior
