Franck Lesieur had introduced in his thesis (now published in an expended and revised version in the Mémoires de la SMF (2007)) a notion of measured quantum groupoid, in the setting of von Neumann algebras and a simplification of Lesieur’s axioms is presented in an appendix of this article. We here develop the notions of actions, crossed-product, and obtain a biduality theorem, following what h...

Introduction: A telemedicine program in oral pathology (TOP) and a preventive examination (POE) to identify lesions was implemented Hualqui, Chile. The objective of this study is describe the results TOP plus POE strategy at CESFAM Chile, during period 2016 2019.

If p:B→G is a Fell bundle over an étale groupoid, then we show that there norm reducing injective linear map j:Cr⁎(G;B)→Γ0(G;B) generalizing the well known j:Cr⁎(G)→C0(G) in case of groupoid.

Orbifold groupoids have been recently widely used to represent both effective and ineffective orbifolds. We show that every orbifold group-oid can be faithfully represented on a continuous family of finite dimensional Hilbert spaces. As a consequence we obtain the result that every orbifold groupoid is Morita equivalent to the translation groupoid of an almost free action of a proper bundle of ...

This paper aims to evaluate residential air conditioning systems' performance enhancement and optimization by adopting a novel functionalized Al2O3 (FAl2O3)–Polyolester (POE) nanolubricant. Comprehensive discussions were conducted on key parameters, including heat absorption, compressor work, cooling capacity, coefficient of (COP), power consumption. Novel FAl2O3 nanoparticles dispersed into th...

Thomas Poe looks at what the future holds for global research using today's technology and provides a clear roadmap showing how to get there efficiently.

An experimental investigation of oil retention and pressure drop characteristics for R1234yf, R134a and R410A with POE 100 is presented, for horizontal and vertical suction lines of 10.2 mm internal diameter. Conditions of operation include a saturation temperature of 13 °C and a superheat of 15 °C, with the superficial vapor velocity and the Oil in Circulation Ratio (OCR) both varied in the ra...

In this paper, we construct an explicit quasi-isomorphism to study the cyclic cohomology of a deformation quantization over a Riemannian étale groupoid. Such a quasi-isomorphism allows us to propose a general algebraic index problem for Riemannian étale groupoids. We discuss solutions to that index problem when the groupoid is proper or defined by a constant Dirac structure on a 3-dimensional t...
