Tornado proximity soundings from the NCEP/NCAR reanalysis data
(2002)
Thermodynamic soundings have been constructed from the reanalysis dataset produced by the National Centers for Environmental Prediction (NCEP) and the National Center for Atmospheric Research (NCAR). This was done to expand ...
NON-NEWTONIAN POWER-LAW FLUID FLOW IN ECCENTRIC ANNULI: CFD SIMULATION AND EXPERIMENTAL STUDY
(2009)
Numerous publications have addressed the problems inherent to calculating wellbore hydraulics in eccentric annulus. The challenge of theoretical and numerical studies of fluid flow in an eccentric annulus is mainly due to ...
Observation and properties of X(3872) at DO.

Temperature Sensitivity of Soil Organic Carbon Mineralization along an Elevation Gradient in the Wuyi Mountains, China
(PLos One, 2013-01-14)
Soil organic carbon (SOC) actively participates in the global carbon (C) cycle. Despite much research, however, our understanding of the temperature sensitivity of soil organic carbon (SOC) mineralization is still very ...
Digital radar receiver design based on highly efficient bandpass sampling FPGA architecture
(2009)
As digital electronics become faster and more efficient, it becomes possible to move the analog/digital interface in a radar downconversion system further towards the antenna. Instead of digitizing radar echoes at the end ...
Ideology of the Islamic State: A Qualitative Analysis of Online Media
(2018-05-11)
This study addresses a lacuna in scholarship on the ideology of the Islamic State resulting from the greater focus on al-Qaeda in scholarship on Salafist jihadism. Through a qualitative analysis of the entire runs of the ...
Open-mindedness in Three Dimensions
(2009)
In this programmatic essay, I approach the question "What is open-mindedness?" through three more specific questions, each designed to foreground a distinct dimension along which the analysis of open-mindedness might ...
The Sobolev approximation in a spherical shell expanding with constant radial velocity.
(2000)
A simple model of line radiative transfer in a circumstellar shell surrounding a supernova is presented. An examination of optical depth in an atmosphere with power-law expansion and a single source of opacity highlights ...
Experimental Evaluation of a Centrifugal Packer-Type Downhole Separator
(2019)
With the ever-increasing decline in production of oil wells, application of artificial lift techniques is becoming inevitable. Beam pumps and electrical submersible pumps are two of the most common artificial lift methods ...
The Effects of Evaporation and Capillary Forces on Fluid Motion, Solute Transport, and Water Content From the Grain Scale to the Continuum Scale in Unsaturated Porous Media
(2019)
This work aimed to explore how fluid motion, solute transport, and water content are influenced by evaporation and capillary forces in unsaturated porous media, across a range of scales. Experiments were conducted from the ...
