• #### Low frequency double electron Muon resonance in fused quartz ﻿

(1983)
Double Electron Muon Resonance (DEMUR) is a double resonance technique for the study of muonium defect centers in insulators and semiconductors. A DEMUR experiment was performed at a low rf frequency to investigate the ...
• #### Low frequency plasma waves at Mars ﻿

(2005)
Mars Global Surveyor's magnetometer/electron reflectometer (MAG/ER) experiment has returned over eight years of observations of low frequency plasma waves produced in the interaction of the solar wind with the Martian ...
• #### Low income family housing within urban contexts ﻿

(1971)
This thesis will be a study of those physical aspects of urban environments which have a bearing on the physical solution of housing for laboring classes in the U.S.A. and Latin America. An attempt will be made to define ...
• #### Low magnetic field transitions of rhenium near the critical temperature ﻿

(1972)
A cryostat was constructed using conventional and superconducting shielding techniques. The ambient magnetic field at the sample was reduced to less than 10 to the -5 Gauss. For the single crystal rhenium sample isothermal ...
• #### Low Resolution ab initio Phasing Method by Modification of Density and Phase in Real and Reciprocal Space ﻿

(2013-09-30)
Phasing problem in X-ray structure determination can be challenging. Several methods, such as Isomorphous Replacement and Molecule Replacement, are frequently used. But their success relies on the availability of either ...
• #### Low Reynolds Number Gaseous Mixing with Applications to Carbon Nanotube Production ﻿

(2016-04-08)
Compared to traditional materials, carbon nanotubes (CNTs) have been shown to exhibit superior properties in mechanical, electrical, and thermal domains, leading researchers to propose and study a number of different new ...
• #### Low temperature vapor - liquid equilibrium. Ternary system: Methane - Ethane - Propane ﻿

(1953)
A vapor recycle type apparatus for obtaining vapor-liquid equilibrium data at low temperatures and high pressures was constructed. Its description and testing are presented. A method of analysis for light hydrocarbons using ...

• #### Low temperature vapor-liquid equilibrium in light hydrocarbon mixtures: Methane-ethane-propane system ﻿

(1957)
Experimental equilibrium data have been determined for 175 mixtures of methane, ethane, and propane. The investigation included temperatures from 50&deg;F to -200&deg;F and pressures up to the critical. A vapor recycle ...

(1966)
• #### Low viscosity channels and the stability of long wavelength convection ﻿

(2010)
Mantle convection simulations with a low viscosity channel, akin to the Earth's asthenosphere, are characterized by long wavelength flow structure. Boundary layer theory predicts that as the viscosity of the channel ...
• #### Low-Energy Charge and Spin Dynamics in Quantum Confined Systems ﻿

(2012-09-05)
Condensed matter systems exhibit a variety of dynamical phenomena at low energy scales, from gigahertz (GHz) to terahertz (THz) frequencies in particular, arising from complex interplay between charge, spin, and lattice. ...
• #### Low-energy elastic scattering of oxygen atoms by atmospheric species ﻿

(1992)
This thesis reports measurements of absolute differential cross sections for elastic scattering of atomic oxygen at 0.5- and 1.5-keV laboratory energies. Measurements for targets of He, Ne, Ar, Kr, Xe, H$\sb2$, N$\sb2$, ...
• #### Low-energy gamma radiation from Cen. X-4 ﻿

(1972)
In July of 1969 a new X-ray source was detected in the southern sky near the constellation Centaurus. This source, identified as Centaurus X-4, displayed a variable intensity in the energy range 3 to 12 keV which at its ...

• #### Low-frequency noise in spin valve sensors ﻿

(1999)
Low frequency noise in giant magnetoresistive spin valves has been studied as a means of optimizing signal to noise ratios and characterizing device performance. The devices studied were sputter deposited NiFe/Cu/NiFe/FeMn ...
