Oil return from the evaporator to the compressor crank case is a critical requirement affected by the refiigerantllubricant properties, gas velocities and piping geometry. Refrigerant R-22 has been successfully used with mineral oil in residential air-conditioning and heat pump systems (AC/HP). R-407C and R-41 OA are two chlorine free HFC refrigerant candidates to replace R-22. This paper descr...

In this paper, we discuss findings from a collaborative self-study conducted on enacting blended approach (i.e. consisting of online and in-person components) to Physical Education Teacher (PETE) course. Data consisted reflective journals recorded conversations. We examine assumptions about the structure, content, pedagogies “blended” approaches using metaphor miscibility, where liquids mix for...

Combining two Bose-Einstein condensates (BECs) may result in a miscible or immiscible mixture, even violent implosion. We theoretically demonstrate that dipolar two-component BECs produce far richer physics than their nondipolar counterparts. Intriguingly, when both components have equivalent dipoles, the transition to immiscibility is largely unaffected by physics, yet dipoles maximally affect...

Glass transition parameters can be used to study the miscibility, or lack of it, in polymer-modified asphalt binders. In this study, contribution thermodynamics mixing glass was quantitatively assessed a differential scanning calorimeter for four binders partially and fully replaced by an epoxy system. The values heat capacity (Cp) and, subsequently temperature (Tg) all were determined quantify...
