Detailed kinetic modeling of dimethoxymethane. Part I: Ab initio thermochemistry and kinetics predictions for key reactions
(Elsevier, 2017-09-06)Despite the great interest in oxygenated methyl ethers as diesel fuel additives and as fuels themselves, the influence of their methylenedioxy group(s) (0-CH2-0) has never been quantified using ab initio methods. In this ... -
Detection of Extended VHE Gamma Ray Emission from G106.3+2.7 with VERITAS
(2009)We report the detection of very-high-energy (VHE) gamma-ray emission from supernova remnant (SNR) G106.3+2.7. Observations performed in 2008 with the VERITAS atmospheric Cherenkov gamma-ray telescope resolve extended ... -
Detection of Pulsed Gamma Rays Above 100 GeV from the Crab Pulsar
(2011)We report the detection of pulsed gamma rays from the Crab pulsar at energies above 100 Gigaelectronvolts (GeV) with the VERITAS array of atmospheric Cherenkov telescopes. The detection cannot be explained on the basis of ... -
Determination of friction coefficient in unconfined compression of brain tissue
(Elsevier, 2012-10)Unconfined compression tests are more convenient to perform on cylindrical samples of brain tissue than tensile tests in order to estimate mechanical properties of the brain tissue because they allow for homogeneous ... -
Determination of survival of wildtype and mutant Escherichia coli in soil
(Bio-protocol, 2017-07-20)E. coli resides in the gastrointestinal tract of humans and other warm-blooded animals but recent studies have shown that E. coli can persist and grow in various external environments including soil. The general stress ... -
Determination of the number of RAD51 molecules in different human cell lines
(Taylor & Francis, 2019-11-15)Knowledge about precise numbers of specific molecules is necessary for understanding and verification of biological pathways. The RAD51 protein is central in the repair of DNA double-strand breaks (DSBs) by homologous ... -
Developing detailed chemical kinetic mechanisms for fuel combustion
(Elsevier, 2018-07-01)This paper discusses a brief history of chemical kinetic modeling, with some emphasis on the development of chemical kinetic mechanisms describing fuel oxidation. At high temperatures, the important reactions tend to be ... -
Development of a 5-component gasoline surrogate model using recent advancements in the detailed H2/O2/CO/C1-C3 mechanism for decoupling methodology
(Elsevier, 2020-08-17)In the present work, a 5-component gasoline surrogate chemical kinetic mechanism has been developed and validated. The first novelty of this mechanism is that a recently advanced H2/O2/CO/C1 detailed sub-mechanism is ... -
Development of a joint hydrogen and syngas combustion mechanism based on an optimization approach
(Wiley, 2016-05-20)A comprehensive and hierarchical optimization of a joint hydrogen and syngas combustion mechanism has been carried out. The Keromnes et al. (Combust Flame, 2013, 160, 995-1011) mechanism for syngas combustion was updated ... -
Development of a rapid Polarized Total Synchronous Fluorescence Spectroscopy (pTSFS) method for protein quantification in a model bioreactor broth
(Wiley, 2021-01-27)Protein quantification during bioprocess monitoring is essential for biopharmaceutical manufacturing and is complicated by the complex chemical composition of the bioreactor broth. Here we present the early-stage development ... -
Development of an ethogram for hutch-housed dairy calves and determination of factors influencing their behaviour
(Elsevier, 2020-11-18)The objectives of this study were to investigate the behaviour of hutch-housed dairy calves, develop an ethogram of general behaviour, and determine whether housing calves in different hutches, day, gender and time of day ... -
Development of Mcl-1 inhibitors for cancer therapy
(Elsevier, 2020-11-24)The myeloid leukemia cell differentiation protein (Mcl-1) is an anti-apoptotic protein of the B-cell lymphoma 2 (Bcl-2) family, which regulates cellular apoptosis. Mcl-1 expression plays a key role in survival of cancer ... -
Development of multipurpose skeletal core combustion chemical kinetic mechanisms
(American Chemical Society, 2021-03-25)Core combustion kinetic mechanisms for small C0¿C4 fuel molecules are not only of the utmost importance in understanding their individual combustion properties but are also the foundation for the development of kinetic ... -
Differences in tension and compression in the nonlinearly elastic bending of beams
(Texas Digital Library, 2009-02)The classical flexure problem of non-linear incompressible elasticity is revisited for elastic materials whose mechanical response is different in tension and compression - the so-called bimodular materials. The flexure ... -
Diffusionrank: a possible penicillin for web spamming
(2007)While the PageRank algorithm has proven to be very effective for ranking Web pages, the rank scores of Web pages can be manipulated. To handle the manipulation problem and to cast a new insight on the Web structure, we ... -
