Multiscale Molecular Modeling Applied to the Upstream Oil & Gas Industry Challenges
Tập 3 - Trang 54-65 - 2020
This review brings an overview based on recent publications of multi-scale
molecular modeling studies applied to the upstream Oil & Gas segment. These
works provide suitable insights on technologies of Oil & Gas interest ranging
from fluid properties under spatial confinement, and the phenomena occurring at
brine-oil-rock interfaces through enhanced oil recovery processes. Within a
broader phenome...
Ubiquitous Health Technology Management (uHTM)
Tập 4 - Trang 47-57 - 2021
The COVID-19 pandemic increased the need for distributed and ubiquitous health
technology management. The eminent risk of Sars-CoV-2 contamination when
visiting a health care establishment requires an efficient allocation of the
technical team. The equipment problems should be quickly identified and fixed to
keep the facility working at its full condition. This article presents a
solution to perfo...
Lactic Acid Extraction from Aqueous Systems by Emulsion Liquid Membrane Separation Process Using Statistical Experimental Design
Tập 2 - Trang 62-76 - 2019
Box-Behnken design was utilized to obtain optimized process condition for
maximizing lactic acid extraction efficiency and initial extraction rate by
emulsion liquid membrane (ELM) process. A mixture of tri-n-octylamine and
tri-n-decylamine (1:1, v/v) was employed as carrier in membrane phase of ELM for
synergic facilitated lactic acid transport. The effect of different process
parameters like lac...
Perspectives on Manufacturing Automation Under the Digital and Cyber Convergence
Tập 1 - Trang 36-47 - 2018
The evolution of industrial automation has been divided into four or five main
cycles of “industrial revolutions,” also called “disruptive innovations” and
“automation revolutions.” The most recent one, started around the 1990s and
still on-going, points to the current perspectives envisioned for the
twenty-first century and perhaps even beyond. In practice, however, it is
difficult to comprehend ...
A Multilayer Proposal to a Smart Home Applied to Healthcare
Tập 4 - Trang 1-14 - 2021
Smart home technology is an up-and-coming field of automation that integrates
different areas, including sensing and electrical automation subsystems,
devices, mechanical and hydraulic systems associated with sophisticated control
and supervising. Recently these systems also received an extra mission to assist
particular users, as older adults or patients who need intensive care. Such a
challenge ...
Green Technology: Transformation of Transpiration Vapor to Mitigate Global Water Crisis
Tập 2 - Trang 26-29 - 2019
The transpiration mechanism has been proposed for rerouting as it is the main
cause of groundwater loss which is also causing significant climate change by
releasing water vapor into the air. Since electrostatic force has the tendency
to tug down the water, thus, a static electricity force creating plastic tank
has been proposed to install at the bottom of plants to capture the
transpiration water...
Evaluation of Natural Radioactivity and Associated Radiological Risks of Farmland Soil: A Study of a Campus Farmland of Osun State University, Nigeria
Tập 7 - Trang 1-8 - 2023
Assessment of activity levels of radionuclides that exist in nature in
agricultural farmland soils is very crucial because of the deleterious effects
that gamma radiation can have on humans, once exposed. This study determined the
radioactivity levels of 232Th, 238U, and40K (radionuclides that exist in nature)
in 60 soil representatives gathered from a Teaching and Research Farm of Osun
State Univ...
