Identification of novel cis-regulatory elements of Eya1 in Xenopus laevis using BAC recombineering
(Nature Publishing Group, 2017-11-03)The multifunctional Eya1 protein plays important roles during the development of cranial sensory organs and ganglia, kidneys, hypaxial muscles and several other organs in vertebrates. Eya1 is encoded by a complex locus ... -
Identification of putative adhesins and carbohydrate ligands of Lactobacillus paracasei using a combinatorial in silico and glycomics microarray profiling approach
(Oxford University Press (OUP), 2019-11-11)Commensal bacteria must colonize host mucosal surfaces to exert health-promoting properties, and bind to gastrointestinal tract (GIT) mucins via their cell surface adhesins. Considerable effort has been directed towards ... -
Identifications and quantitative measurements of narcotics in solid mixtures using near-IR Raman spectroscopy and multivariate analysis
(1999)Raman spectroscopy offers the potential for the identification of illegal narcotics in seconds by inelastic scattering of light from molecular vibrations. In this study cocaine, heroin, and MDMA were analyzed using near-IR ... -

Identifying the sources and sinks of CDOM/FDOM across the Mauritanian Shelf and their potential role in the decomposition of superoxide (O2- )
(Frontiers Media, 2016-08-03)Superoxide (O−2O2-) is a short lived reactive oxygen species (ROS) formed in seawater by photochemical or biological sources, it is important in the redox cycling of trace elements and organic matter in the ocean. The ... -
Ignition characteristics of 2-methyltetrahydrofuran: An experimental and kinetic study
(Elsevier, 2016-10-10)The present paper elucidates oxidation behavior of 2-methyltetrahydrofuran (2-MTHF), a novel second-generation biofuel. New experimental data sets for 2-MTHF including ignition delay time measurements in two different ... -
An ignition delay and kinetic modeling study of methane, dimethyl ether, and their mixtures at high pressures
(Elsevier ScienceDirect, 2014-09-29)The development of accurate chemical kinetic models capable of predicting the combustion of methane and dimethyl ether in common combustion environments such as compression ignition engines and gas turbines is important ... -
An ignition delay time and chemical kinetic modeling study of the pentane isomers
(Elsevier, 2016-10-26)Ignition delay times of n-pentane, iso-pentane, and neo-pentane mixtures were measured in two shock tubes and in a rapid compression machine. The experimental data were used as validation targets for the model described ... -
Ignition delay time measurements of diesel and gasoline blends
(Elsevier, 2020-09-23)Blends of diesel and gasoline can be used to achieve certain desired ignition characteristics in advanced compression ignition engine concepts. In this work, ignition delay times were measured for two blends of diesel and ... -
Ignition delay times, laminar flame speeds, and mechanism validation for natural gas/hydrogen blends at elevated pressures
(Elsevier, 2013-12-30)New experimental ignition delay time data measured in both a shock tube and in a rapid compression machine were taken to determine the increase in reactivity due to the addition of hydrogen to mixtures of methane and natural ... -
