The Case For A Moratorium On Deep-Sea Mining: The International Seabed Authority, Indigenous Rights, And Marine Ecosystems In The Eastern Pacific, Afrah A. Qoqandi

UC Law Environmental Journal

The rising interest in deep-sea commercial exploitation has sparked a powerful debate over the environmental and social justice implications of mining the ocean’s depths for valuable minerals. Deep-sea mining targets polymetallic nodules found on the seabed, containing metals critical for green technologies like electric vehicles and solar cells. The Clarion-Clipperton Zone (“CCZ”) in the eastern Pacific is estimated to hold more nickel, manganese, and cobalt than all terrestrial resources combined. As one of the last largely untouched ecosystems, deep-sea mining in the CCZ raises significant concerns about the irreversible harm to its biodiversity and the disruption to Indigenous communities reliant …

School of Medicine Publications

Myeloid/lymphoid neoplasms with eosinophilia and tyrosine kinase fusions (M/LN-eo-TK) are uncommon but highly treatable disorders. Among them, FIP1L1::PDGFRA–driven disease is distinguished by marked eosinophilia and multisystem involvement that can rapidly reverse with targeted therapy. We describe a 50-year-old man with uncontrolled diabetes who presented with progressive dyspnea, abdominal discomfort, and painful necrotic scrotal ulcers. Laboratory testing revealed leukocytosis with a striking absolute eosinophil count of 22.1 × 10³/µL, while imaging showed pulmonary infiltrates, small-bowel inflammation, and splenomegaly. Bone marrow examination demonstrated hypercellularity with prominent eosinophilic proliferation. Fluorescence in situ hybridization confirmed a PDGFRA rearrangement with CHIC2 deletion, establishing the diagnosis …

G-Topological Groupoids, Osman Mucuk

Turkish Journal of Mathematics

In the groupoid theory, it is unclear that a topological groupoid's quotient groupoid with the quotient topology is topological.  In this paper, we approach this problem considering  G-methods and G-convergence. We define  G-topological groupoid, which agrees with the sequential version of a topological groupoid in the particular case G=lim, and give some counterexamples. Then, we extend the usual properties of topological groupoids to the G-topological groupoids. We also prove that a G-topological groupoid's quotient groupoid is  G-topological groupoid when a normal subgroupoid is suitably chosen. This result enables us to obtain examples of topological quotient groupoids in a particular case.

On Almost Kenmotsu Manifolds Admitting Nearly Vacuum Static Equations With Applications, Uday Chand De, Krishnendu De, Sudhakar Kumar Chaubey

Turkish Journal of Mathematics

In this article, we study certain characteristics of nearly vacuum static equations on almost Kenmotsu manifolds. It is established that an η-Einstein almost Kenmotsu manifold allowing nearly vacuum static equations is of constant scalar curvature and either the solution is trivial or, the manifold reduces to an Einstein manifold. Next,  nearly vacuum static equations on (κ,μ)-almost Kenmotsu manifolds and generalized (κ,μ)'-nullity distribution are considered and we obtain several interesting results. Moreover, we illustrate that if a 3-dimensional Kenmotsu manifold allows nearly vacuum static equations, then the manifold is locally isometric to the hyperbolic space Η3(-1). After that, we investigate a …
