Thermodynamic Model Of Co2 Deposition In Cold Climates, Sandra K. S. Boetcher, Ted Von Hippel, Matthew J. Traum Dec 2019

Thermodynamic Model Of Co2 Deposition In Cold Climates, Sandra K. S. Boetcher, Ted Von Hippel, Matthew J. Traum

Publications

A thermodynamic model, borrowing ideas from psychrometric principles, of a cryogenic direct-air CO2-capture system utilizing a precooler is used to estimate the optimal CO2 removal fraction to minimize energy input per tonne of CO2. Energy costs to operate the system scale almost linearly with the temperature drop between the ingested air and the cryogenic desublimation temperature of CO2, driving siting to the coldest accessible locations. System performance in three Arctic/Antarctic regions where the proposed system can potentially be located is analyzed. Colder ambient temperatures provide colder system input air temperature yielding lower CO2 removal energy requirements. A case is also …

A Framework To Reveal Clandestine Organ Trafficking In The Dark Web And Beyond, Michael P. Heinl, Bo Yu, Duminda Wijesekera

Journal of Digital Forensics, Security and Law

Due to the scarcity of transplantable organs, patients have to wait on long lists for many years to get a matching kidney. This scarcity has created an illicit market place for wealthy recipients to avoid long waiting times. Brokers arrange such organ transplants and collect most of the payment that is sometimes channeled to fund other illicit activities. In order to collect and disburse payments, they often resort to money laundering-like schemes of money transfers. As the low-cost Internet arrives in some of the affected countries, social media and the dark web are used to illegally trade human organs. This …
