We construct the H-von Neumann regular radical for H-module algebras and show that it is an H-radical property. We obtain that the Jacobson radical of twisted graded algebra is a graded ideal. For twisted H-module algebra R, we also show that rj(R#σH) = rHj(R)#σH and the Jacobson radical of R is stable, when k is an algebraically closed field or there exists an algebraic closure F of k such tha...

Given a quasianalytic system Q = (Qn)n∈N of sheaves, denote by Qn the local ring of Q-analytic function germs at 0 ∈ Rn. This paper introduces the concepts of Lojasiewicz radical and geometric spectrum SpegQn ⊂ SperQn. Via the Lojasiewicz inequality, a version of the Nullstellensatz for Qn is given. We establish a quasianalytic version of the Artin–Lang property for Qn. Finally, we prove, by me...

One of the principal models of magnetic sensing in migratory birds rests on the quantum spin dynamics of transient radical pairs created photochemically in ocular cryptochrome proteins. We consider here the role of electron spin entanglement and coherence in determining the sensitivity of a radical pair-based geomagnetic compass and the origins of the directional response. It emerges that the a...

We give an example of a pure group that does not have the independence property, whose Fitting subgroup is neither nilpotent nor definable andwhose soluble radical is neither soluble nor definable. This answers a question asked by E. Jaligot in May 2013. The Fitting subgroupof a stable group is nilpotent and definable (F.Wagner [11]). More generally, the Fitting subgroup of a group that satisfi...

The electrolysis of toluate esters leads smoothly to the formation of the radical of the alkyl fragment. This property has been used to develop a new electrochemical deoxygenation reaction.

protection of biological systems against radiation damage is of paramount importance during accidental and unavoidable exposure to radiation. several physico-chemical and biological factors collectively contribute to the damage caused by radiation and are, therefore, targets for developing radioprotectors. chemicals capable of scavenging free radicals, relieving oxidative stress, promoting anti...

This paper demonstrates a new substantive finding kinetic property in advertising, defined as direction changes in the paths of moving on-screen ad elements, enhances consumer judgments of product novelty. Across six studies, we first outline an inference-based theory as to why the novelty-enhancing effect of kinetic property manifests – kinetic property generates impressions of how visually li...

qct calculations were performed to study the behavior of energized nh2oh formed by association collision of nh2 radical with oh radical. a potential energy surface that describes the behavior of the title reaction has been constructed by interpolation of ab initio data. h2o, hon, hno, nh3, o, h2no, cis or trans-honh, and h products and two vibrationally energized nh2oh and nh3o adducts were obs...

The best described pharmacological property of flavonoids is their capacity to act as potent antioxidant that has been reported to play an important role in the alleviation of diabetes mellitus. Flavonoids biochemical properties are structure dependent; however, they are yet to be thoroughly understood. Hence, the main aim of this work was to investigate the antioxidant and antidiabetic propert...

A Banach algebra A with radical R is said to have property (S) if the natural mapping from the algebraic tensor product 2 A ® A onto A is open, when A ® A is given the protective norm. The purpose of this note is to provide a counterexample to Zinde's claim that when A is commutative and R is one dimensional the fulfillment of property (S) in A implies its fulfillment in the quotient algebra A/R .
