Study of Water-cooled Auto-cascade Refrigeration Cycle with a Low Temperature of﹣60 ℃
Zhileng xuebao, 2015 A new water-cooled auto-cascade refrigeration cycle(WACR) using a binary refrigerant mixture is presented, which adopts a condenser-phase separator instead of a condenser and an evaporative separator in traditional auto-cascade refrigeration cycle.

Research on Condensation Heat Transfer with Presence of Non-condensable Gases
Zhileng xuebao, 2006 The effect of non-condensable gases in the progress of condensation heat transfer were described.In this research,a new way of eliminating this effect in an auto-cascade refrigeration cycle was proposed.In addition,the calculation for the coefficient of ...

Business Strategy and the Environment, EarlyView.ABSTRACT Circular product design (CPD) is central to advancing the circular economy by enabling the narrowing, slowing, and closing of resource flows. Yet, its implementation remains persistently challenging for firms. Prior research has largely framed these challenges as discrete barriers, overlooking the structural contradictions embedded in CPD ...

JSFA reports, EarlyView.Abstract Background Territorial food production is a well‐known quality trait, which is attracting new customer preferences for different agricultural products. In this context, many microbreweries and agricultural breweries started to cultivate their own small hopyard to exploit the so‐called “terroir” effect.

That sinkin’ feeling: Environmentally induced distress on a disappearing island
Medical Anthropology Quarterly, EarlyView.Abstract Residents of Tangier Island, Virginia, a subsiding island in the Chesapeake Bay, embody psychosocial dimensions of environmental change. Analysis of ethnographic data shows islanders’ experiences and articulations of anxiety, panic, and despair as “that sinkin’ feeling,” resulting from the stress of living with the long‐term threat of imminent
