Analytic comparison between three high-throughput commercial SARS-CoV-2 antibody assays reveals minor discrepancies in a high-incidence population
( Nature Research , 2021 , Article)Performance of three automated commercial serological IgG-based assays was investigated for assessing SARS-CoV-2 "ever" (past or current) infection in a population-based sample in a high exposure setting. PCR and serological ... -
Analytic Prioritization of Indoor Routes for Search and Rescue Operations in Hazardous Environments
( Blackwell Publishing Inc. , 2017 , Article)Applications to prioritize indoor routes for emergency situations in a complex built facility have been restricted to building simulations and network approaches. These types of applications often failed to account for the ... -
Analytical approach to the Darcy–Lapwood–Brinkman equation
( Elsevier , 2007 , Article)Three exact solutions are obtained for flow through porous media, as governed by the Darcy–Lapwood–Brinkman model, for a given vorticity distribution. The resulting flow fields are identified as reversing flows; stagnation ... -
Analytical methods for mercury speciation, detection, and measurement in water, oil, and gas
( Elsevier B.V. , 2020 , Article Review)Mercury related compounds are released in massive and alarming amounts due to increased human activities such as the processing of hydrocarbons in the petroleum industry. The contamination due to mercury compounds is ... -
Analytical model of I-bar clasps for removable partial dentures
( Elsevier Inc. , 2021 , Article)Objective: Clasps of removable partial dentures (RPDs) often suffer from fatigue stress that leads to plastic deformation, loss of retention, and RPD failure. Recently, computer-based technologies were proposed to optimize ... -
Analytical models for predicting oil recovery from immiscible CO2 injection: A literature review
( Elsevier , 2022 , Article Review)The enhanced oil recovery is applied to increase oil recovery from oil reservoirs. The immiscible CO2 injection oil recovery method is suitable for reservoirs with low pressure. This paper presents a review of literature ... -
