On Nilpotent Elements of Skew Polynomial Rings

open access: yesJournal of Mathematical Extension, 2012
We study the structure of the set of nilpotent elements in skew polynomial ring R[x; α], when R is an α-Armendariz ring. We prove that if R is a nil α-Armendariz ring and α t = IR, then the set of nilpotent elements of R is an α-compatible subrng of ...

Endocrine Disruptive Effects of the Herbicides Linuron, Chloridazon and Metribuzin on Bovine Granulosa Cells

open access: yesReproduction in Domestic Animals, Volume 61, Issue 4, April 2026.
ABSTRACT Linuron, chloridazon and metribuzin are herbicides thought to have potential endocrine disruption (ED) effects. This study investigated the effects of linuron, chloridazon and metribuzin on bovine granulosa cell viability and oestrogen (E2) and progesterone (P4) secretion in vitro.

On Nilpotent Elements and Armendariz Modules

open access: yesMathematics
For a left module MR over a non-commutative ring R, the notion for the class of nilpotent elements (nilR(M)) was first introduced and studied by Sevviiri and Groenewald in 2014 (Commun. Algebra, 42, 571–577).

Assessing Age‐Specific Variability in Microplastic Intake Through Seafood Consumption: A Case Study in Central Java, Indonesia

open access: yesJournal of Food Science, Volume 91, Issue 3, March 2026.
ABSTRACT Microplastics (MPs) are frequently detected in seafood. However, the extent to which seafood consumption contributes to MP intake remains uncertain. Previous studies on MP intake in humans did not consider interindividual variability in exposure.

Prevalence of Adverse Events in Mexico Using the Institute for Healthcare Improvement—Global Trigger Tool Method: A Retrospective Study

open access: yesJournal of Evaluation in Clinical Practice, Volume 32, Issue 2, March 2026.
ABSTRACT Rationale Globally, adverse events (AEs) are a major contributor to mortality, often arising from healthcare management rather than patients' underlying conditions. Aims and Objectives This study aimed to estimate the prevalence of AEs in three different hospitals in central‐north Mexico using the Institute for Healthcare Improvement Global ...

Nutrient Peak Shifts in the Arctic: Implications for Migratory Herbivores Under Climate Change

open access: yesJournal of Biogeography, Volume 53, Issue 2, February 2026.
ABSTRACT Aim Quantifying how the timing and spatial variability of Arctic vegetation nutrient peaks are projected to shift under climate change, and assessing potential consequences for migratory herbivores that rely on seasonal synchrony with peak plant quality. Location Circumpolar Arctic, with emphasis on tundra regions.

Update and Comparative Analysis of Food Environment Policies in Mexico: Implementation of the Healthy Food Environment Policy Index in 2016 and 2024

open access: yesObesity Reviews, Volume 27, Issue 1, Page 1-15, January 2026.
ABSTRACT Introduction Mexico faces a public health crisis due to the rising prevalence of obesity and noncommunicable diseases, primarily driven by unhealthy food environments. Objective To conduct a second implementation of the Food Environment Policy Index in Mexico to assess policy implementation levels related to healthy food environments and to ...

Idempotent McCoy Rings and Their Properties

open access: yesJournal of Mathematics, Volume 2026, Issue 1, 2026.
This paper introduces idempotent McCoy rings, extending McCoy rings by incorporating idempotent elements, and explores their key properties. We provide examples and a counterexample showing that not every idempotent McCoy ring is McCoy. Our results show that if B is a Boolean ring, then the upper triangular matrix ring TnB is idempotent McCoy, but this

Solar Flare Activity, 1937–2024: Introducing the New Hemispheric Solar Flare Index (hSFI) in the Context of 2024's Major Solar Storm Events

open access: yesSpace Weather, Volume 23, Issue 11, November 2025.
Abstract A new daily composite of the solar flare index (SFI) and the hemispherically‐resolved versions (hSFI) are presented for 1937 to 2024. The data set confirms that the northern hemisphere (NH) dominated solar flare activity during Solar Cycles 17 to 21, but that the southern hemisphere has dominated from Solar Cycle 22 to present.

The Correlation Between Exposure to Violence and Parental Monitoring: Differences Between Mothers and Fathers From Palestinian–Israeli Families

open access: yesChild &Family Social Work, Volume 30, Issue 4, Page 657-668, November 2025.
ABSTRACT In this study, I investigated the correlations between retrospectively reported experiences of child abuse in the family‐of‐origin and exposure to community violence as adults on parental monitoring among Palestinian–Israeli parents. A sample of 760 parents (453 mothers, 59.6%) participated in the study.
