On the join of subnormal subgroups [PDF]
Proceedings of the American Mathematical Society, 1974 Let G \mathfrak {G} be the class of finitely generated groups. If the join of finitely many subnormal X = s n X \mathfrak {X} = sn\mathfrak {X}

Groups in which all Subgroups are Subnormal-by-Finite [PDF]
Advances in Group Theory and Applications, 2016 We prove that a locally finite group G in which every subgroup is a finite extension of a subnormal subgroup of G is nilpotent-by-\v Cernikov.

Finite Groups whose Cyclic Subnormal Subgroups Satisfy Certain Permutability Conditions [PDF]
Advances in Group Theory and Applications, 2016 Finite groups in which each cyclic subnormal subgroup is semipermutable, S-semipermutable or seminormal are investigated.

On some groups whose subnormal subgroups are contranormal-free [PDF]
International Journal of Group TheoryIf $G$ is a group, a subgroup $H$ of $G$ is said to be contranormal in $G$ if $H^G = G$, where $H^G$ is the normal closure of $H$ in $G$. We say that a group is contranormal-free if it does not contain proper contranormal subgroups.

Permutable subnormal subgroups of finite groups [PDF]
Archiv der Mathematik, 2016 The aim of this paper is to prove certain characterization theorems for groups in which permutability is a transitive relation, the so called PT -groups.

Subnormal Subgroups of Division Rings
Canadian Journal of Mathematics, 1963 Let K be a division ring. A subgroup H of the multiplicative group K′ of K is subnormal if there is a finite sequence (H = A0, A1, . . . , An = K′) of subgroups of K′ such that each Ai is a normal subgroup of Ai+1.

Survival of Hematologic Malignancy In Patients With Early‐Stage Chronic Kidney Disease (SHIP‐CKD) [PDF]
Cancer Medicine, Volume 15, Issue 6, June 2026.ABSTRACT Background Chronic kidney disease (CKD) is a common comorbidity among cancer patients and may influence treatment options and outcomes. However, the independent effect of CKD in patients with hematologic malignancies remains unclear. Methods We conducted a retrospective cohort study using electronic medical records of 1238 adult patients ...

Hemodynamic changes in pregnancies with impaired fetal growth: A systematic review and meta‐analysis [PDF]
Acta Obstetricia et Gynecologica Scandinavica, Volume 105, Issue 2, Page 215-224, February 2026.Maternal cardiovascular adaptation is altered in pregnancies complicated by impaired fetal growth. From the second trimester onwards, lower cardiac output and increased total peripheral vascular resistance emerge, highlighting the need for early hemodynamic monitoring and potential interventions in at‐risk pregnancies.

Digital therapy using dichoptic visual perceptual learning to improve stereopsis in children with intermittent exotropia [PDF]
Frontiers in Digital HealthBackgroundIntermittent exotropia impairs binocular vision and stereopsis in children, and visual perceptual learning (VPL) with dichoptic stimulation offers a potential therapy.

Journal of Pure and Applied Algebra, 1992 Let H be a subgroup of the finite group G and let SG(H) be the set of all elements g of G such that H is subnormal in 〈H, g〉.
