Ramakrishna Mission Vivekananda Educational and Research Institute, formerly Ramakrishna Mission Vivekananda University or simply Vivekananda University, is a education institute deemed-to-be-university headquartered at Belur, West Bengal, with campuses spanning multiple states in India. Established with the idea of actualizing Swami Vivekananda's vision of education, the institute is administered by the Ramakrishna Mission. The university provides courses on subjects as varied as rural and tribal development, disability management and special education, fundamental science education and Indian cultural and spiritual heritage..
The Central Sets Theorem is one of the main results in arithmetic Ramsey theory, proved by Furstenberg in [6]. Later in [4], De, Hindman, and Strauss proved a stronger version of the Central Sets Theorem. In [1], Beiglböck proved the multidimensional extension of the Central Sets Theorem.In this article, we establish a multidimensional extension and provide a complete ultrafilter characterization of the Stronger Central Sets Theorem. Additionally, we develop a polynomial generalization of this result. Our approach utilizes tools from the algebra of the Stone–Čech compactification of discrete semigroups. Several applications are presented.
Coastal and marine fishing communities are critical to global food security and the blue economy, yet they face escalating environmental and economic pressures. This systematic review synthesises two decades (2004–2024) of research on financial mechanisms supporting these communities, addressing a fragmented understanding of how tools like microloans, subsidies, and insurance influence socioeconomic resilience and marine conservation. Through a bibliometric analysis of Web of Science data, the review investigates four interconnected themes: (i) the evolution of global research trends and collaborations in fisheries finance, (ii) the impact of distinct financial mechanisms on the economic development of small-scale fisheries, (iii) the contribution of financial support to community livelihoods, specifically income and employment, and (iv) the alignment of this research with key Sustainable Development Goals (SDGs).

The genetic basis of mesocotyl length and its associated loci is critical for improving seedling emergence and establishment in direct-seeded rice systems. This study investigated the phenotypic variation and genetic architecture of mesocotyl length in a diverse panel of 192 rice genotypes using a genome-wide association study (GWAS) approach. The panel, comprising germplasm accessions, advanced breeding lines, and released varieties, was genotyped using a 44 K SNP array, resulting in 19,613 high-quality polymorphic SNPs after stringent filtering. Phenotypic evaluation revealed continuous variation in mesocotyl length, ranging from 2.48 to 18.98 mm, with high broad-sense heritability (71.2
A strong peak of the X-ray spectra observed in collisions of 6.6 MeV/u ^238U on a ^64Ni Frégeau et al. in Phys Rev Lett 108:122701, 2012) was attributed to be originating from the compound nucleus ^302_120Ubn based ions. Though extremely small evaporation residue cross section (10^-9 fb) and nuclear decay properties favor such X-ray emission from ^302_120Ubn , but such a strong X-ray peak from a small fusion cross section is not possible. Furthermore, X-ray emission from the ion formed with the compound nucleus must be affected by the Doppler effects. Thereby, the origin of this X-ray peak ought to be something else. Interestingly, this particular X-ray peak not affected by the Doppler effect is found to be belonging to the two-electron one-photon (TEOP) process of thorium that is produced from the α -breakup reaction of the uranium projectiles. We show that the TEOP process emits the Doppler-free radiations and we can analyse the entire observed spectra by accounting this process in the atomic structure calculations. Remarkably, the intensity of this peak is nearly equal to that of thorium K_α peak. Such an unusual feature is possible from uranium X-ray absorption to the thorium excited states having a vacancy in the K-shell and and then a doubly excited state is formed with the fully vacant K-shell. Thus, we reveal that the particular peak does not at all originate from the compound nucleus rather it comes from the thorium TEOP process. Now this Doppler-free radiation phenomenon can help us to analyse correctly the spectra observed in the X-ray region where both the atomic and nuclear events prevail.
Abstract This article critically examines uranium mining as a global public and environmental health crisis, rather than merely a technical or industrial activity. It discusses how extractive operations produce cumulative, long-term harms ranging from radioactive exposure and ecological degradation to intergenerational health risks that fall most heavily on communities already marginalised by social and political inequalities. Drawing on the secondary sources of data and illustrative case studies, including those from Indigenous territories, it maps the deeply uneven distribution of risks and benefits across the uranium supply chain. These cases reveal how uranium extraction magnifies environmental injustice by (re)producing inequitable exposures, limiting community participation and denying recognition to affected peoples. We also interrogate the ethical pressure at the heart of contemporary sustainability debates: the promotion of nuclear energy as a climate solution while ignoring the toxic material realities on which it depends. As both a critical synthesis and a call for systemic reform, we argue for justice-oriented policies grounded in public health equity, environmental responsibility and genuinely participatory governance. Ultimately, rethinking uranium mining requires more than technological improvements; it demands confronting the structural injustices rooted in extractive economies and centring the lived experiences, rights and knowledge systems of the communities who bear the greatest burdens.
