The question of the existence of an analogue, in the framework of central simple algebras with involution, of the notion of Pfister form is raised. In particular, algebras with orthogonal involution which split as a tensor product of quaternion algebras with involution are studied. It is proven that, up to degree 16, over any extension over which the algebra splits, the involution is adjoint to...

OBJECTIVE To examine the location and degree of endothelial nitric oxide synthase (eNOS) protein expression in hemangioma growth, involution, and during propranolol therapy. DESIGN Cross-sectional study. SETTING University hospital. PATIENTS Pediatric patients with hemangiomas. INTERVENTIONS Fresh human hemangioma specimens at various stages of development were harvested. Effective prop...

in this paper, we define the notions of ultra and involution ideals in $bck$-algebras. then we get the relation among them and other ideals as (positive) implicative, associative, commutative and prime ideals. specially, we show that in a bounded implicative $bck$-algebra, any involution ideal is a positive implicative ideal and in a bounded positive implicative lower $bck$-semilattice, the not...

The aim of this study was to determine the effects oxytocin and carazolol administration on uterine blood flow by pulsed-wave Doppler ultrasonography (USG) evaluate influences these drugs involution. Thirty primiparous suckling Kiwircik ewes were divided into 3 groups: carazolol, oxytocin, control. underwent transcutaneous B-mode USG in 1st week after birth, examinations continued via transrect...

Objective: Alongside its role as a potent vasoconstrictor in the cardiovascular system, endothelin-1 (ET-1) is involved numerous physiological processes. Its expression thought to be an important function for both breastfeeding and newborns since it occurs especially during pregnancy lactation. In this study, we projected effects of ET-1 on mammary gland physiology employing transgenic mice. Ma...

Involution of lymphoid tissues in relation to age has not been defined for bottlenose dolphins (Tursiops truncatus). Twenty-five bottlenose dolphins from the coast of Texas and western Louisiana were examined and complete necropsies were performed with histological samples taken of nearly all tissues. Ages ranged from several days to 27 years. The histology of four lymphoid organs-thymus, phary...

Let n | m be positive integers with the same prime factors, such that p3 | n for some prime p. We construct a noncrossed product division algebra D with involution ∗, of index m and exponent n, such that D possesses a Baer ordering relative to the involution ∗. Using similar techniques we construct indecomposable division algebras with involution possessing a Baer

We present recent results about Capelli polynomials with involution or graded and their asymptotics. In the associative case, asymptotic equality between codimensions of $T$-ideal generated by polynomial rank $k^2+1$ matrix algebra $M_k(F)$ was proved. This result extended to superalgebras. Recently, similar have been determined authors in case algebras superalgebras involution.

In this article, we provide counterexamples to a conjecture of M. Pellegrini and P. Shumyatsky which states that each coset the centralizer an involution in finite non-abelian simple group $G$ contains odd order element, unless $G=\text{PSL}(n,2)$ for $n\geq 4$. More precisely, show does not hold alternating $A_{8n}$ all 2$.

Through the research on relationship between social occupation involution and entrepreneurial development ability, this study tested 250 college students' ability involution, in order to changes of under various variables its with involution. literature research, questionnaire survey mathematical statistics, paper studies relevant theories obtains data College Students' through survey, using sp...
