Use of electrochemical sensors for measurement of air pollution: correcting interference response and validating measurements
Autor: E. S. Cross, L. R. Williams, D. K. Lewis, G. R. Magoon, T. B. Onasch, M. L. Kaminsky, D. R. Worsnop, J. T. Jayne
Publikováno v: Atmospheric Measurement Techniques, Vol 10, Pp 3575-3588 (2017)
The environments in which we live, work, and play are subject to enormous variability in air pollutant concentrations. To adequately characterize air quality (AQ), measurements must be fast (real time), scalable, and reliable (with known accuracy,

Publikováno v: Atmospheric Measurement Techniques, Vol 6, Iss 11, Pp 3271-3280 (2013)
We have designed and characterized a new inlet and aerodynamic lens for the Aerodyne aerosol mass spectrometer (AMS) that transmits particles between 80 nm and more than 3 μm in vacuum aerodynamic diameter. The design of the inlet and lens was optim

Quasiparticle and hybrid density functional methods in defect studies: An application to the nitrogen vacancy in GaN
Autor: Enrico Bellotti, Sahar Sharifzadeh, D. K. Lewis, Masahiko Matsubara
Publikováno v: Physical Review B. 96
Defects in semiconductors can play a vital role in the performance of electronic devices, with native defects often dominating the electronic properties of the semiconductor. Understanding the relationship between structural defects and electronic fu

cDNA cloning and transcriptional regulation of the vitellogenin receptor from the imported fire ant, Solenopsis invicta Buren (Hymenoptera: Formicidae)
Autor: Patricia V. Pietrantonio, L. L. Keeley, M.-E. Chen, D. K. Lewis
Publikováno v: Insect Molecular Biology. 13:195-204
We describe the cloning of the first hymenopteran vitellogenin receptor (VgR) cDNA from the imported fire ant, Solenopsis invicta, an invasive pest. Using reverse transcription polymerase chain reaction and rapid amplification of cDNA ends, fragments

Portable Laser Induced Breakdown Spectroscopy (LIBS) Sensor for Detection of Biological Agents
Autor: J. Wormhoudt, David W. Hahn, D. K. Lewis, A. Freedman, B. W. Smith
Our Phase I work demonstrated the feasibility of a mobile LIBS system for the detection of biological agents. This is a very demanding application, in part because of the need to detect threat particles in the presence of a much larger number of beni

A hexamerin protein, AgSP-1, is associated with diapause in the boll weevil(1)
Autor: D K., Lewis, D, Spurgeon, T W., Sappington, L L., Keeley
Publikováno v: Journal of insect physiology. 48(9)
The objective of this research was to identify a reliable biochemical indicator for diapause (dormancy) in the boll weevil, Anthonomus grandis. Hemolymph polypeptides from reproductive and diapausing weevils were compared using denaturing sodium dode

Who decides when to start preventive treatment? A questionnaire survey to compare the views of different population subgroups
Autor: D K Lewis, S Barton
Publikováno v: Journal of epidemiology and community health. 57(4)
Lipid lowering drugs lower the risk of ischaemic cardiovascular events. The absolute benefit is highest in people at greatest risk of having an event in the near future, but adverse effects and costs are similar whatever the baseline risk. The decisi
