Low temperature catalytic adsorption of NO over activated carbon honeycomb (ACH) monoliths

open access: yesRevista Facultad de Ingeniería Universidad de Antioquia, 2013
An activated carbon honeycomb (ACH) monolith was developed for the adsorption of NO at 30ºC. For ACH monoliths preparation carboxymethylcellulose (CMC) and coal tar pitch were used as binder and co-binder, respectively. The effects of the addition of O2

Multistage Evolution in Transverse Aeolian Ridges

open access: yesRemote Sensing, 2021
Transverse aeolian ridges (TARs) are poorly understood relict aeolian Martian surface features. Processes that create TARs are not well-constrained, and understanding their formation is complicated since they appear to share some features of ripples ...

Torrefaction as a Valorization Method Used Prior to the Gasification of Sewage Sludge

open access: yesEnergies, 2019
The gasification and torrefaction of sewage sludge have the potential to make the thermal utilization of sewage sludge fully sustainable, thus limiting the use of expensive fossil fuels in the process. This includes sustainability in terms of electricity

Recent Aqueous Activity on Mars Evidenced by Transverse Aeolian Ridges in the Zhurong Exploration Region of Utopia Planitia

open access: yesGeophysical Research Letters, 2023
Aqueous activities on Mars have gradually declined since the Noachian (>3.7 Ga). Although water can be stored in the subsurface during the latest epochs, geomorphological evidence is still limited. In this study, we used in situ imaging and spectral data

The Generation Game: Has Modern Contemporary Total Ankle Replacement (TAR) Improved Survivorship?

open access: yesFoot & Ankle Orthopaedics, 2022
Category: Ankle Introduction/Purpose: Total ankle replacements (TARs) provide pain relief with preservation of movement and function. The most successful TARs are either 2nd or current 3rd generation in design, whilst 4th generation implants are steadily

Tars: Timeliness-aware Adaptive Replica Selection for Key-Value Stores

open access: yes, 2017
In current large-scale distributed key-value stores, a single end-user request may lead to key-value access across tens or hundreds of servers. The tail latency of these key-value accesses is crucial to the user experience and greatly impacts the revenue.

Distinguishing Nymphal Instars of \u3ci\u3eMesovelia Mulsanti\u3c/i\u3e (Heteroptera: Mesoveliidae) [PDF]

open access: yes, 2017
The five nymphal instars of Mesouelia mulsanti can be separated by the number of rows of setae on the second abdominal tergum. Fifth instars can be separated from younger instars and from each other by the degree of development of the external ...
