Modeling the Behavior of Frost Growth on Finned Tube Heat Exchanger [PDF]

open access: yesEngineering and Technology Journal, 2014
A quasi-steady finite-volume model was developed for modeling a plain-finround-tube heat exchanger under frosted conditions. In this study, the heat and mass transfer characteristics of heat exchangers during frost formation process are analyzed ...

Quantum fluctuation theorem for heat exchange in the strong coupling regime [PDF]

open access: yesPhys. Rev. B, 84, 161414 (2011), 2011
We study quantum heat exchange in a multi-state impurity coupled to two thermal reservoirs. Allowing for strong system-bath interactions, we show that a steady-state heat exchange fluctuation theorem holds, though the dynamical processes nonlinearly involve the two reservoirs.

Determination of ADP/ATP translocase isoform ratios in malignancy and cellular senescence

open access: yesMolecular Oncology, EarlyView.
The individual functions of three isoforms exchanging ADP and ATP (ADP/ATP translocases; ANTs) on the mitochondrial membrane remain unclear. We developed a method for quantitatively differentiating highly similar human ANT1, ANT2, and ANT3 using parallel reaction monitoring. This method allowed us to assess changes in translocase levels during cellular

Cleaning Schedule Optimization of Heat Exchanger Networks Using Particle Swarm Optimization [PDF]

open access: yesarXiv, 2015
Oil refinery is one of industries that require huge energy consumption. The today technology advance requires energy saving. Heat integration is a method used to minimize the energy comsumption though the implementation of Heat Exchanger Network (HEN). CPT is one of types of Heat Exchanger Network (HEN) that functions to recover the heat in the flow of

Numerical study of an exhaust heat recovery system using corrugated tubes and twisted tape inserts [PDF]

open access: yes, 2014
Thesis (M.S.) University of Alaska Fairbanks, 2014Diesel engine generators are the major power source for small communities in cold regions. Diesel generators waste about 1/3 of their fuel energy in the form of heat through exhaust gas.

A non‐fluorescent immunohistochemistry method for measuring autophagy flux using MAP1LC3/LC3 and SQSTM1 as core markers

open access: yesFEBS Open Bio, EarlyView.
We introduce an immunohistochemistry method to measure autophagy flux, highlighting the active degradation and recycling of cellular waste. This cost‐effective approach uses tissue samples to track key markers like LC3 and SQSTM1, revealing how cells maintain health or respond to diseases such as cancer. It bridges the gap between research and clinical

Review on Research Status and Prospects of Two-phase Flow Distribution in Microchannel Heat Exchanger

open access: yesZhileng xuebao, 2021
The non-uniform distribution of two-phase flow usually happens in a microchannel heat exchanger, which significantly reduces the performance of the microchannel heat exchanger.

Artificial Receptor in Synthetic Cells Performs Transmembrane Activation of Proteolysis

open access: yesAdvanced Biology, EarlyView.
Transmembrane signaling is the hallmark of living cells and is among the highest challenges for the design of synthetic cells. Herein, an artificial receptor based on the chemistry of self‐immolative linkers is used to communicate information across the lipid bilayer, for transmembrane activation of enzymatic activity. Abstract The design of artificial,
