A Hierarchical VvbHLH30‐VvERF70‐VvACS2 Module Orchestrates Ethylene Biosynthesis and Cold Adaptation in Grapevine

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Ethylene is a key gaseous phytohormone that plays crucial roles in regulating plant growth, development and stress responses. However, ethylene‐associated biosynthetic and transcriptional regulatory mechanisms governing cold‐adaptation responses in plants remain poorly understood.

Research on Condensation Heat Transfer with Presence of Non-condensable Gases

open access: yesZhileng 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 Relation of Performance Parameters for a 150K Auto-Cascade Refrigeration System

open access: yesResearch Journal of Applied Sciences, Engineering and Technology, 2013
The performance parameters of a single compressed and four-stage segregating auto-cascade refrigeration system were developed in this study. The temperature of the cryogenic tank went down relatively slow with the evaporating temperature and the refrigerant temperature for W. When the state of system is steady, the suction pressure of the compressor is

Endocrine and androgenic response to altitude training in professional cyclists

open access: yesThe 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).

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

open access: yesAdvances 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

A Framework for Emergency Department–Integrated Hepatitis C Test‐and‐Treat in the United States

open access: yesJournal of Viral Hepatitis, Volume 33, Issue 6, June 2026.
ABSTRACT Despite the availability of curative, direct‐acting antiviral therapy, hepatitis C virus elimination remains incomplete. Losses across the care cascade continue to limit impact, from initial diagnosis to sustained virologic response. Fewer than 1/3 of individuals ultimately achieve cure. These gaps reflect a delivery system that does not align

A Comprehensive Review of Waste‐Derived Materials for Solar Still Performance Enhancement

open access: yesAdvanced Materials Interfaces, Volume 13, Issue 9, 5 May 2026.
Solar desalination reduces energy use and produces freshwater sustainably, but its productivity is limited and cannot meet rising demand. Thus, solar desalination system improvements are sought to boost water productivity. Waste materials are abundantly available and burden the environment, making them low‐cost enhancers for solar desalination systems.

SECOND LAW ANALYSIS OF AUTO CASCADE REFRIGERATION CYCLE USING MIXED HYDROCARBON REFRIGERANT R-600A /R-290/ R170

open access: yesJurnal Teknologi, 2018
Experimental and theoretical analysis investigations are achieved on the performance of the three-stage auto cascade refrigeration system. Energy and exergy analysis of auto cascade system is considered using zeotropic mixed hydrocarbon refrigerant R-600a/R-290/R-170 at different mass fractions of (25.5/42.5/32), (24.25/42.75/33), (23/43/34) and (20.5 ...
