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 ...

The study of thermodynamic properties of zeotropic mixtures of R600a/R23/R14

Advances in Mechanical Engineering, 2017
Thermodynamic properties of zeotropic mixtures of R600a/R23/R14 have been investigated and calculated based on the established mathematical model. The deviations of bubble pressure and vapor composition between the simulation results and the experimental

Consumption of anthropogenic foods influences the nutritional and reproductive condition of hunter‐harvested black bears

Wildlife Biology, EarlyView.
The consumption of human food subsidies influences ecological processes, and can affect individual behavior and fitness with population level changes in abundance and distribution. American black bears Ursus americanus often consume human food subsidies, which have been correlated with increased bear body size, age‐specific fertility and mortality ...

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

Endocrine and androgenic response to altitude training in professional cyclists

The Journal of Physiology, EarlyView.
Abstract figure legend Steroidal and endocrine variables are altered during altitude training. Abstract This study investigated endocrine and steroidal blood markers in 31 male elite cyclists monitored over 7 weeks, including a 3 week altitude training camp either at 2050 m (n = 19) or 3000 m (n = 12).

Tocilizumab and Dexamethasone Reduce TNF‐α and IL‐33 and Oxidative Stress in Kidney Tissue in Oleic Acid‐Induced ARDS Model

Journal of Biochemical and Molecular Toxicology, Volume 40, Issue 6, June 2026.
Oleic acid causes ARDS‐associated AKI. Tocilizumab and dexamethasone reduces ARDS‐induced kidney injury. The width of the filtration slits increases in kidney injury. Tocilizumab and dexamethasone suppress TNF‐a and IL‐33. ABSTRACT The most common extrapulmonary organ injury in cases of acute respiratory distress syndrome (ARDS) is acute kidney injury (
