The properties of gold nanoparticles (GNP) holds promising potential for drug delivery, diagnostics, plasmonic photothermal therapy of diseases, electronics, catalysis, and photovoltaics (Liu et al., 2006; Huang et al., 2003; Thompson, 2007;...
"Judd's industrially manufactured, modular pieces, developed from 1966 onwards, were stubbornly empirical investigations of specific materials and visual effects. He shunned mystification and openly declared the nature of his structures. The...
The motivation to determine a viable alternative to petroleum based energy has risen in recent years due to increased greenhouse gas emissions, environmental pollution, and the fear of exhausting oil and natural gas reserves. Biodiesel derived from...
Interactions between chemokines and their receptors are involved in organ- specific homing and propagation of metastatic breast cancer (BrCa) cells. BrCa cells express higher levels of CXCR4 and CXCR7 mRNA and cell surface protein, than normal...
As more attention is focused toward carbon dioxide emissions into the environment, conversion of CO2 to useful chemicals can utilize the extra carbon dioxide captured from power plant stack gas, instead of sequestration. The mainstream method of...
Background: Emerging circulatory support devices that operate in counterpulsation to the native heart require synchronized timing of device ejection and filling on a beat-to-beat basis with the native heart using a patient's ECG. Surface leads are...
Few previous studies have compared microbial communities in subterranean and surface environments. Chemical analyses used to characterize the surface and cave microbial environments indicated limited exchange between surface and subsurface waters....
Several technical and economic obstacles currently hamper the industrial development of ethanol from biomass. One of the key bottlenecks is the slow kinetics of the enzymatic hydrolysis of cellulose, and the subsequent rate reduction as the...
This thesis is a study of my current body of work, both formally and conceptually. It begins with an Introduction, explaining the origin of the term hybrid and the distinct advantages as well as disadvantages hybridization has on a species. It also...
Cerium dioxide or ceria, CeO2, has been widely used in industry as catalyst for automotive exhaust controls, chemical mechanical polishing (CMP) slurries, and high temperature fuel cells because of its unique metal oxide properties. This well-known...
Chlamydia trachomatis is an obligate intracellular pathogen that utilizes a type III secretion system to enter mammalian cells and establish an intracellular niche. TARP, the translocated actin recruitment protein, is a chlamydial invasion protein...

Large electric motor with freight cars filled with coal attached to it inside a mineshaft. . A man stands between the motor and first car, possibly on the back of the motor. Wires run across the ceiling. The shaft is supported by large wood...
Three men stand in a mineshaft in front of a car filled with coal while four more stand behind it. They are each wearing caps with headlamps. Title: 7057 Loading Cage with Car of Coal at Bottom of Shaft, Scranton, Pa. Text on left: Keystone View...
Remote terminal units (RTUs) are perimeter supervisory control and data acquisition (SCADA) devices that measure and control actual physical devices. Cyber security was largely ignored in SCADA for many years, and the cyber security issues that now...
Computer vision; Pattern recognition systems; Human face recognition (Computer science)
Humans have the uncanny ability to perceive the world in three dimensions (3D), otherwise known as depth perception. The amazing thing about this ability to determine distances is that it depends only on a simple two-dimensional (2D) image in the...
Various vision tasks are usually confronted by appearance variations due to changes of illumination. For instance, in a recognition system, it has been shown that the variability in human face appearance is owed to changes to lighting conditions...
"As an African-American who is able to pass as 'white', Piper has written eloquently of the social and institutional prejudices that surface when she divulges her racially mixed identity. In a text entitled 'Flying' of 1987 she wrote: 'I am...
Air void structure in hardened concrete is critical to its durability. This project mainly focuses on investigating the air void system in hardened concrete with the microscopic analysis Linear Traverse Method specified by ASTM Specification...
