G. B. Shaw, Pygmalion. An Introduction
No full textStarting from a presentation of English theatre before G. B. Shaw, London intellectual and ideological background, Shaw's relation to Ibsen and his support to the women's liberation movement, this study analyses his theatre production covering the years 1890-1950, and examines the play Pygmalion paying attention to themes and characters, dramatic structure and style

No full textb-Generalized Skew Derivations on Multilinear Polynomials in Prime Rings
No full textLet R be a prime ring of characteristic different from 2, Qr be its right Martindale quotient ring and C be its extended centroid. In this paper we define b-generalized skew derivations of prime rings. Then we describe all possible forms of two b-generalized skew derivations F and G satisfying the condition F(x)x − xG(x) = 0, for all x ∈ S, where S is the set of the evaluations of a multilinear polynomial f(x1, ..., xn) over C with n non-commuting variables. Several potential research topics related to our current work are also presented. © 2021, The Author(s), under exclusive license to Springer Nature Switzerland AG

OBJECTIVE:
The present study was undertaken to determine whether improved vasodilatory function accompanies increased insulin sensitivity in overweight, insulin-resistant subjects (OW) and type 2 diabetic patients (T2DM) who participated in an 8-wk exercise training regimen.
DESIGN:
Before and after training, subjects had euglycemic clamps to determine insulin sensitivity. Brachial artery catheterization was done on another occasion for measurement of vasodilatory function. A lean, healthy, untrained group was studied as nonexercised controls.
RESULTS:
Training increased oxygen consumption (VO2) peak [OW, 29 +/- 1 to 37 +/- 4 ml/kg fat-free mass (FFM).min; T2DM, 33 +/- 2 to 43 +/- 3 ml/kg FFM.min; P < 0.05] and improved insulin-stimulated glucose disposal (OW, 6.5 +/- 0.5 to 7.2 +/- 0.4 mg/kg FFM.min; T2DM, 3.8 +/- 0.3 to 4.2 +/- 0.3 mg/kg FFM.min; P < 0.05) in insulin resistance. OW and T2DM, before training, had decreased acetylcholine chloride (ACh)- and sodium nitroprusside-mediated vasodilation and decreased reactive hyperemia compared with lean controls. Training increased the vasodilatory response to ACh [OW (30 microg ACh/min), 12.2 +/- 3.4 to 19 +/- 4.2 ml/100 g.min; T2DM (30 microg ACh/min), 10.1 +/- 1.5 to 14.2 +/- 2.1 ml/100 g.min; P < 0.05] in both groups without affecting nitroprusside response.
CONCLUSION:
Because vasodilatory dysfunction has been postulated to contribute to insulin resistance, the exercise-induced improvement in vasodilatory function may signify changes in the endothelium that could contribute to the improvement in insulin sensitivity observed after aerobic exercise training
Certain functional identities involving a pair of generalized skew derivations with nilpotent values on Lie ideals
No full textLet R be a prime ring of characteristic different from 2, Q(r) its right Martindale quotient ring, L a non-central Lie ideal of R (i.e., L,R not equal 0), n >= 1 a fixed integer, F and G two generalized skew derivations of R, associated with the same automorphism alpha of R. If (F(xy)-G(x)y)(n) = 0, for any x,y is an element of L, then there exists a is an element of Q(r) such that , for any x is an element of R, unless when R satisfies the standard polynomial identity s(4)(x(1), ..., x(4))
Optical properties of an interacting large polaron gas
No full textThe normal state conductivity, , of a
system of interacting large polarons is calculated within the Random
Phase approximation and some numerical results are presented.
The behaviour of the
optical absorption as a function of the charge carrier density and of the
temperature is analyzed for different values of the electron-phonon
coupling constant.
It is shown that exhibits features similar to those observed
in the infrared spectra of the cuprates
An Innovative Mission Management System for Fixed-Wing UAVs
No full textThis paper presents two innovative units linked together to build the main frame of a UAV Mis- sion Management System. The first unit is a Path Planner for small UAVs able to generate optimal paths in a tridimensional environment, generat- ing flyable and safe paths with the lowest com- putational effort. The second unit is the Flight Management System based on Nonlinear Model Predictive Control, that tracks the reference path and exploits a spherical camera model to avoid unpredicted obstacles along the path. The control system solves on-line (i.e. at each sampling time) a finite horizon (state horizon) open loop optimal control problem with a Genetic Algorithm. This algorithm finds the command sequence that min- imizes the tracking error with respect to the ref- erence path, driving the aircraft far from sensed obstacles and towards the desired trajectory
