Absolute Intensities for the O 2 1.27 ym Continuum Absorption

December 1, 1999
Author(s)
B Mate, C Lugez, Gerald T. Fraser, Walter J. Lafferty
Collision-induced absorption coefficients for the 1.27 υm band of O 2 have been measured at a resolution of 0.5 cm -1 and an optical pathlength of L = 84 m using a Fourier-transform spectrometer and 2 m long White-type multipass absorption cell. Spectra

Extracellular and Intracellular Chorismate Mutases From Mycobacterium tuberculosis H 37 R v : Characterization of the Hypothetical Gene Products Rv1885c and Rv0948c

October 12, 2021
Author(s)
Sung Kim, Sathyavelu K. Reddy, G B. Vasquez, B C. Nelson, A M. Davis, S. Patterson, Prasad T. Reddy
Two ORFs Rv1885c and Rv0948c from the genome of Mycobacterium tuberculsosis H37Rv were identified as putative chorismate mutases. We reported earlier that Rv1885c is indeed a chorismate mutase (CM) with a 33 amino acid cleavable signal sequence in a

Velocity and Temperature Structure of Medium-Scale Pool Fires

June 22, 2021
Author(s)
Kunhyuk Sung, Ryan Falkenstein-Smith, Anthony Hamins
A series of measurements was conducted using a bidirectional probe to characterize the upward speed in the plumes of medium-scale pool fires burning a variety of gaseous and liquid fuels. Time-averaged local measurements of the upward velocity were

DNA-directed nanofabrication of high-performance carbon nanotube field-effect transistors

May 22, 2020
Author(s)
Ming Zheng, Jeffrey A. Fagan, Jason K. Streit, Mengyu Zhao, Yahong Chen, Kexin Wang, Zhi Zhu, Wei Sun
Scaling the channel pitch of field-effect transistors (FETs) is one prerequisite towards future ultra-scaled technology nodes. While lithography has been the foundational tool during the scaling of bulk materials, bio- fabrication is promising for

Development of Standard Reference Material (SRM) 2973 Vitamin D Metabolites in Frozen Human Serum (High Level)

… ± 2.1 nmol/L for 25(OH)D3 and reference values of 1.59 ± 0.05 nmol/L for 25(OH)D2 and 5.23 ± 0.20 nmol/L for … values for 24R,25(OH)2D3 were assigned to SRM 2973 (7.51 nmol/L ± 0.26 nmol/L) and SRM 972a Level 1 (6.38 nmol/L …

Composition and Carrier Concentration Dependence of the Electronic Structure of InyGa1-yAs1-xNx Films With Nitrogen Mole Fraction Less Than 0.012

November 1, 2005
Author(s)
Youn S. Kang, Lawrence H. Robins, Anthony Birdwell, Alexander J. Shapiro, W. R. Thurber, Mark D. Vaudin, M M. Fahmi, D Bryson, S N. Mohammad
The electronic structure of Si-doped InyGa1-yAs1-xNx films on GaAs substrates, grown bynitrogen-plasma-assisted molecular-beam epitaxy, was examined by photoreflectance PR spectroscopy at temperatures between 20 and 300 K. The films were approximately 0.5

Premixed Rapid-Setting Calcium Phosphate Composites for Bone Repair

January 1, 2005
Author(s)
Lisa E. Carey, Hockin D. Xu, Carl Simon Jr., Shozo Takagi, Laurence C. Chow
… time for these new premixed CPCs ranged from 5.3 min to 7.9 min, significantly faster than 61.7 min for a premixed control CPC reported previously (p < 0.05). SEM examination revealedthe formation of nano-sized …

In-Situ Burning in the Marshland Environment - Recovery and Regrowth of Spartina Alterniflora, Spartina Patens, and Sagittaria Lancifolia Plants

March 1, 2003
Author(s)
I A. Mendelson, Q N. Lin, Nelson P. Bryner, William D. Walton, W H. Twilley, J V. Mullin
In a series of in-situ burns involving 330 plant mesocosms, including Spartina Alterniflora, Spartina Patens, Distichlis spicata, and Sagittaria Lancifolia sods were exposed to burning diesel fuel or crude oil. Oil spilled in sensitive wetlands pose unique

Continuous Monitoring of Particles in an Occupied Home for the Year 2000

February 19, 2017
Author(s)
L A. Wallace, Cynthia H. Reed
Continuous monitors were employed for one year in an occupied townhouse to measure ultrafine, fine and coarse particles, air change rates, wind speed and direction, temperature and relative humidity. A main objective was to document long-term variation in
