Abstract

The current study aimed to assess the neuroprotective effect of Zn and Fe oxide nanoparticles biofabricated by Taverniera glabra in alloxan-induced diabetic rats. The experimental animals (160–200 g) were divided into nine groups (n = 9). The blood glucose, body weight, glucose-6-phosphate dehydrogenase (G6PD), superoxide dismutase (SOD), catalase test (CAT), lipid peroxidation (TBARS), glutathione (GSH), and acetylcholinesterase (AChE) activities were determined. Oral administration of nanoparticles and T. glabra methanol extract (TGME; 10 and 15 mg/kg b.w) significantly decreased the glucose level, increased the body weight, controlled the quantitative level of G6PD, and significantly decreased the levels of ALT, ALP, cholesterol, and creatinine. Moreover, TGME and their Zn and Fe oxide nanoparticles significantly restored the antioxidant enzymes (SOD, CAT, GPx, and GSH) that decreased during induced diabetes. In the diabetic group, a significant increase in TBARS was noted and recovered in diabetic animals (p < 0.05) as compared to glibenclamide. The AChE activity was significantly recovered by nanoparticles and TGME both in the blood and brain of the diabetic group (p < 0.05). Taken together, it can be suggested that TGME and Zn and Fe oxide nanoparticles significantly improved memory and could be considered as an effective biogenic nanomaterial for diabetes, Alzheimer’s disease, and oxidative stress.

Abstract

AG-groupoids (non-associative structure) are basic structures in Flocks theory. This theory mainly focuses on distance optimization, motion replication, and leadership maintenance with a wide range of applications in physics and biology. In this paper, we define some new types of fuzzy ideals of AG-groupoids called (α, β)-fuzzy bi-ideals, (α, β)-fuzzy interior ideals, (β̄, ᾱ)-fuzzy bi-ideals, and (β̄, ᾱ)-fuzzy interior ideals, where α, β∈{∈γ, qδ, ∈γ∨qδ, ∈γ∧qδ} and ᾱ, β̄∈{⋶γ, q̄δ, ⋶γ∨q̄δ, ⋶γ∧q̄δ}, with α≠∈γ∧qδ and β̄≠⋶γ∧q̄δ. An important milestone achieved by this paper is providing the connection between classical algebraic structures (ordinary bi-ideals, interior ideals) and new types of fuzzy algebraic structures [(∈γ, ∈γ∨qδ)-fuzzy bi-ideals, (∈γ, ∈γ∨qδ)-fuzzy interior ideals]. Special attention is given to (∈γ, ∈γ∨qδ)-fuzzy bi-ideals and (⋶γ, ⋶γ∨q̄δ) -fuzzy bi-ideals.

34. Phase transitions in Li-doped Ag(NbxTa₁-x)O₃ perovskite ceramics

Abstract

Ceramics in the solid solution series, Ag(NbxTal-x)03 were fabricated to study their phase transitions and functional properties. As Ta concentration increased, the onset temperature of the M-phase transitions decreased in agreement with the Pawelcyck phase diagram. Electron diffraction and Raman spectroscopy revealed that the reduction in onset temperature may be attributed to a decrease in the correlation length and magnitude of cation displacements as the less polarisable Ta replaced the highly polarisable Nb ion in the B06 octahedra. For compositions with x = 0.75, a previously unreported phase transition was observed at ~ 3 l5K. Further studies were also performed on Li doped AgNb03, AgNbl/2 Ta 1/203 and AgTa03 compositions to determine whether their functional properties could be modified or enhanced. For > 0.05% Li doped AgNb03, the structure transformed from orthorhombic, Pbcm (√2ap,√2ap,4ap) to a new structure with a unit cell, √2ap√2ap,6ap, where ap is the pseudocubic perovskite lattice parameter. The new cell may be envisaged as arising from a complex modulated tilt system in which blocks of 3 in- phase tilted octahedra are rotated in antiphase with respect to each other around the c- axis. The onset of this transition resulted in asymmetry of the M3-M2 transition but there was no discernible improvement in ferroelectric properties at room temperature. For Li doped AgNbl/2 Ta1/2O3, the correlation length of cation displacements and to a lesser extent octahedral tilting decreased according to electron diffraction and Raman spectroscopy as Li concentration increased. The decrease in correlation length manifested itself as a highly perturbed domain structure at the solubility limit (~ 15 mol% Li) and resulted in convergence of the M-phase transitions to give a single broad dielectric response at the solubility limit. For Li doped AgTaO3, there were no apparent changes in the structure at room temperature. However, temperature dependent dielectric measurements clearly indicated that Li substitution had induced the onset of a ferroelectric phase transition in contrast to the incipient behaviour of AgTaO3. The temperature of the ferroelectric transitions increased with increase in Li concentration up to the solubility limit (~ 15 mol %.). The onset of the ferroelectric transition was also observed by Raman spectroscopy but further work is required to determine its precise nature.

Abstract

Several applied fields dealing with decision-making process may not be successfully modeled by ordinary fuzzy sets. In such a situation, the interval-valued fuzzy set theory is more applicable than the fuzzy set theory. Using a new approach of “quasi-coincident with relation”, which is a central focused idea for several researchers, we introduced the more general form of the notion of (α, β)-fuzzy interior ideal. This new concept is called interval-valued (∈, ∈ ∨ qk˜)$( \in ,{\rm{ }} \in \; \vee \;{{\rm{q}}_{\tilde k}})$-fuzzy interior ideal of ordered semigroup. As an attempt to investigate the relationships between ordered semigroups and fuzzy ordered semigroups, it is proved that in regular ordered semigroups, the interval-valued (∈, ∈ ∨ qk˜)$( \in ,{\rm{ }} \in \; \vee \;{{\rm{q}}_{\tilde k}})$-fuzzy ideals and interval-valued (∈, ∈ ∨ qk˜)$( \in ,{\rm{ }} \in \; \vee \;{{\rm{q}}_{\tilde k}})$-fuzzy interior ideals coincide. It is also shown that the intersection of non-empty class of interval-valued (∈, ∈ ∨ qk˜)$( \in ,{\rm{ }} \in \; \vee \;{{\rm{q}}_{\tilde k}})$-fuzzy interior ideals of an ordered semigroup is also an interval-valued (∈, ∈ ∨ qk˜)$( \in ,{\rm{ }} \in \; \vee \;{{\rm{q}}_{\tilde k}})$-fuzzy interior ideal.
