Módulos irreducibles y radical de Jacobson [PDF]

Es un trabajo que introducirá las nociones de primitividad y semiprimitividad en anillos. Para ello se analizarán los estrechamente relacionados módulos irreducibles, en nuestro caso, módulos a izquierda, y las representaciones de anillos.

From Flybys to Sample Return: A Review of Space Probes and Robotic Sampling Technologies for Small Bodies

Journal of Field Robotics, EarlyView.
ABSTRACT As a crucial puzzle piece of deep space exploration, exploring small bodies can provide significant scientific insights and valuable mineral resources. Unlike missions to the Moon and Mars, small‐body missions pose distinct technical challenges, including communication delays, weak gravity, and uncertain environments. This paper reviews a full

River‐Scale Evaluation of a Floating LED Light Array for Behavioral Guidance of American Eel

River Research and Applications, EarlyView.
ABSTRACT Exploiting the sensory physiology of migratory fishes to guide them away from hazards like hydroelectric turbines is of interest to regulatory agencies and hydropower operators to achieve conservation and management goals. Here we describe a river‐scale experiment where out‐migrating adult American eel (Anguilla rostrata) were tracked ...

A Characterization of Commutative Group Rings Whose Units Are Feckly Trivial

Mathematics
Characterizing specific types of units in group rings in terms of the Jacobson radical constitutes a frequently investigated problem in the theory of group rings.

The Krull radical, k-primitive rings, and critical rings

International Journal of Mathematics and Mathematical Sciences, 1982
We generalize results on the Krull radical, k-primitive rings, and critical rings from rings with identity to rings which do not necessarily contain identity.

On the Jacobson radical of strongly group graded rings [PDF]

, 1994
summary:For any non-torsion group $G$ with identity $e$, we construct a strongly $G$-graded ring $R$ such that the Jacobson radical $J(R_e)$ is locally nilpotent, but $J(R)$ is not locally nilpotent.

Contribution of the Baobab Value Chain to Equitable Rural Livelihoods and Poverty Alleviation in Ghana

Sustainable Development, EarlyView.
ABSTRACT Non‐timber forest products (NTFPs) are central to income diversification and livelihood resilience in Sub‐Saharan Africa. However, the welfare implications of baobab commercialisation remain underexplored. This study addresses this gap by analysing the contribution of the baobab value chain to household income, poverty reduction, and income ...

On Weakly (2, ϱ)-Ideals in Noncommutative Rings

Journal of Mathematics
In this paper, we investigate weakly 2,ϱ-ideals (w-2,ϱ-ideals) in noncommutative rings, where ϱ denotes a special radical. We demonstrate, supported by counterexamples, that these ideals serve as generalizations of weakly ϱ-ideals and 2,ϱ-ideals ...
