This paper presents the detailed design and analysis of an asymmetric fin tube condenser. And the heat transfer performance of the asymmetric fin tube condenser is simulated with the fluent software. Based on the simulation results, an optimal model of the asymmetric-finned tube condenser is designed. The actual model is experimentally studied on air conditioners and contrasted with the symmetr...

The upper airway serves as air conditioner, filter, and warning device. Two neurological modalities, olfaction and trigeminal chemoreception, inform us of the chemical qualities of the air we breathe. A number of poorly understood conditions, including nonallergic rhinitis, irritant-induced rhinitis, odor-triggered asthma, odor-triggered panic attacks, chemical-induced olfactory dysfunction, an...

Moisture contamination is a major factor in sealant application, often determining clinical success or failure. A new enamel conditioner using HNO3 (2.5%) has been introduced that does not require a water rinse after etching. The aim of this study is to compare etching characteristics using sealant retention from shear bond strength tests for traditional etch conditioning using H3PO4 (37%) and ...
