Sensitivity analysis and optimization of a CO2 centrifugal compressor impeller with a vaneless diffuser
(Springer, 2021-04-14)
Fluid flow in centrifugal compressors is complex and turbulent, making it difficult to achieve a robust equipment design. In this work, a computational fluid dynamics (CFD) analysis is conducted on the periodical domain ...
Same-different discrimination tests with interstimulus delays up to one day
(Food Nutrition Press IncTrumbullEUA, 1999)
Development of a sequential injection-square wave voltammetry method for determination of paraquat in water samples employing the hanging mercury drop electrode
(SPRINGER HEIDELBERG, 2010)
This work describes the development and optimization of a sequential injection method to automate the determination of paraquat by square-wave voltammetry employing a hanging mercury drop electrode. Automation by sequential ...
Sequential determination of Cd and Cr in biomass samples and their ashes using high-resolution continuum source graphite furnace atomic absorption spectrometry and direct solid sample analysis
(2013)
High-resolution continuum source graphite furnace atomic absorption spectrometry, because of the use of only one radiation source for all elements, offers the possibility of sequential determination of two or more elements ...
Determination of picloram in waters by sequential injection chromatography with UV detection
(Sociedade Brasileira de Química, 2010)
This paper describes a sequential injection chromatography procedure for determination of picloram in waters exploring the low backpressure of a 2.5 cm long monolithic C18 column. Separation of the analyte from the matrix ...
Determinação sequencial de cromo, tálio, cádmio,chumbo, cobre e antimônio em concentrado polieletrolítico para hemodiálise por voltametria de redissolução através de um gradiente de pH
(Universidade Federal de Santa MariaBRQuímicaUFSMPrograma de Pós-Graduação em Química, 2010-02-05)
The sequential voltammetric determination of chromium, thallium, cadmium, lead, copper and antimony, present as contaminants in dialysate concentrates (CPHD), is
presented herein. These concentrates contain a very high ...
Spectrophotometric determination of sulphate in automotive fuel ethanol by sequential injection analysis using dimethylsulphonazo(III) reaction
(2006)
A sensitive SIA method was developed for sulphate determination in automotive fuel ethanol. This method was based on the reaction of sulphate with barium–dimethylsulphonazo(III) leading to a decrease on the magnitude of ...
Determinação de elementos terras raras por espectrometria de absorção atômica de alta resolução com fonte contínua por chama
(Universidade Federal de Santa MariaBrasilQuímicaUFSMPrograma de Pós-Graduação em QuímicaCentro de Ciências Naturais e Exatas, 2018-08-29)
In the present work, two methods of determination of rare earth elements by high resolution continuum source flame AAS was developed, being a sequential and a simultaneous method. The sequential method allowed the determination ...
The cost-effectiveness of 10 antenatal syphilis screening and treatment approaches in Peru, Tanzania, and Zambia
(Wiley, 2015)
OBJECTIVE: Rapid plasma reagin (RPR) is frequently used to test women for maternal syphilis. Rapid syphilis immunochromatographic strip tests detecting only Treponema pallidum antibodies (single RSTs) or both treponemal ...
Sequential design of dynamic experiments in modeling for optimization of biological processes
(Elsevier B.V., 2009-08)
Finding optimal operating conditions fast with a scarce budget of experimental runs is a key problem to speed up the development and scaling up of innovative bioprocesses. A methodology for model-based design of dynamic ...
