Real-time Model for Leak Detection and Positioning of Liquid Pipelines in the Refrigeration System

Zhileng xuebao, 2015
The real-time model which is widely used in the detection of long pipeline leakage is applied to detect ammonia leakage in the pipeline of refrigeration systems in cold stores. The pipeline of refrigeration system with R22 is used to simulate the ammonia

Numerical Simulation of the Ammonia-leakage Diffusion in Ammonia Refrigeration Room

Zhileng xuebao, 2017
In this study, an ammonia refrigeration room was selected as a typical scenario. Computational fluid dynamics (CFD) was applied to study the rules of the ammonia-leakage diffusion. The ammonia-leakage diffusion in a refrigeration room with up-down ventilation and without ventilation was numerically simulated using the Fluent CFD software package.

Fluorescence Sensing of Anions Like Adenosine 5ʹ‐Triphosphate With pH‐Gated Porous Dye‐Loaded Cerasomes

Small, EarlyView.
The development of gated systems enabling controlled pore opening offers new opportunities for sensing applications. This study explores dye loading in porous and non‐porous cerasomes and pH‐dependent ATP‐triggered gating via polyamine anchors. Porous cerasomes were synthesized using block‐co‐polymers, enabling controlled proton influx and fluorescence‐

An Overview of High‐Temperature Superconducting Cables in DC Systems: Unlocking Potential for High‐Voltage DC Networks

High Voltage, EarlyView.
ABSTRACT This paper provides an overview of high‐temperature superconducting (HTS) cables in DC systems, with a focus on their deployment in high‐voltage DC (HVDC) networks. The assessment of HTS cable properties—such as extremely low electrical resistance, high current‐carrying capacity and a compact geometry—and their comparison with those of ...

What Outcomes Matter in Vital Pulp Therapy? Current Concepts and Challenges

Australian Dental Journal, EarlyView.
ABSTRACT Vital pulp therapy (VPT) has re‐emerged as a practical and biologically sound alternative for managing deep caries and carious pulp exposures. Although its clinical use is now widespread, the outcomes used to judge the success of VPT remain inconsistent and often difficult to compare across studies.

Leakage Research of Split-type Air-conditioner using R290 as Refrigerant

Zhileng xuebao, 2013
The ozone depletion potential (ODP) and global warming potential (GWP) of HCFCs and HFCs are higher than hydrocarbons (HCs). R290 is perfect in environmental protection and energy saving performance.

6‐Nitrodopamine as a Novel Mediator of Prostatic Smooth Muscle Function in Mouse and Human

Andrology, EarlyView.
ABSTRACT Background Epithelium‐derived catecholamines contribute to local regulation of genitourinary smooth muscle function, but the role of the endogenous 6‐nitrodopamine (6‐ND) in the prostate remains unknown. Objectives To determine whether 6‐ND is produced by mouse and human prostate and its role in smooth muscle regulation.
