A family of quotients of the Rees algebra
, 2014 A family of quotient rings of the Rees algebra associated to a com- mutative ring is studied. This family generalizes both the classical concept of idealization by Nagata and a more recent concept, the amalgamated duplication of a ring.

On the Gorensteinness of Rees algebras over local rings [PDF]
Nagoya Mathematical Journal, 1986 Let (A, m, k) be a Noetherian local ring and I an ideal of A. We set and call this graded A-algebra the Rees algebra of I. The importance of the Rees algebra R(I) is in the fact that Proj R(I) is the blowing up of Spec A with center in V(I). The Cohen-Macaulayness of Rees algebras was studied by many mathematicians. In [GS] S. Goto any Y. Shimoda gave

Journal of Periodontology, EarlyView.Abstract Background Free soft tissue autografts (FSTA) harvested from a patient's palate are frequently associated with significant postoperative morbidity. Several wound dressings have been applied to the palatal donor site with the aim of reducing postoperative complications and improving wound healing.

Equations of multi-Rees Algebras
, 2018 In this thesis we describe the defining equations of certain multi-Rees algebras. First, we determine the defining equations of the multi-Rees algebra $R[I^{a_1}t_1,\dots,I^{a_r}t_r]$ over a Noetherian ring $R$ when $I$ is an ideal of linear type.

Gorensteinness in Rees algebras of powers of parameter ideals
, 2022 This paper gives a necessary and sufficient condition for Gorensteinness in Rees algebras of the $d$-th power of parameter ideals in certain Noetherian local rings of dimension $d\ge 2$.

Journal of Plant Nutrition and Soil Science, EarlyView.ABSTRACT Cadmium (Cd2+) contamination in agricultural soils has been reported to pose risks to crop productivity, food safety, and human health. This review synthesizes current knowledge on the mechanisms by which essential (S, Zn, Fe, Mg, K, Ca) and beneficial (Si, Se, rare earth elements) elements mitigate Cd2+ toxicity in plants.

Rees Algebras of F-regular Type
, 2002 We study the F-regularity of Rees algebras R(I)=A[It] in terms of the global F-regularity of the blowing-up X=ProjR(I) of SpecA. As it reads, global F-regularity is a global analog of strong F-regularity defined via splitting of Frobenius maps in prime ...

Journal of Pediatric Gastroenterology and Nutrition, EarlyView.Abstract Objectives We evaluated the efficacy and safety of teduglutide in a real‐world cohort in which national reimbursement policies required treatment interruptions. The primary outcomes were reduction in parenteral support (PS) and treatment‐related adverse effects, and the secondary outcome was the impact of the mandated withdrawal periods ...

Leader Succession and Strategic Change: The Role of Leader's Subgroups Size
Strategic Change, EarlyView.ABSTRACT Research suggests that new CEO successors drive strategic change through the subgroup of their immediate collaborators. However, it remains unclear how this subgroup is configured. In this research, we address this limitation by introducing a new concept of “CEO's subgroup size” (the number of TMT members in the CEO's subgroup).
