Finite Element Analysis Of Helicopter Main Rotor Hub Plates To Evaluate The Possibility Of Increasing The Time To Retirement
(Mechanical Engineering, 2009-09-16)
Rotorcraft main rotor systems have multiple components that are subject to very high loads and moments. These loads and moments dictate the life expectancy of the parts based upon the components material of composition. ...
Multi-criteria Assessment For Supporting Freeway Operations And Management Systems
(Civil & Environmental Engineering, 2009-09-16)
Freeway traffic congestion represents an increasing concern for urban areas throughout the United States. In addition, faced with limited roadway expansion alternatives, transportation agencies are considering investment ...
Investigation Of Redox-active Ruthenium(II) Polypyridyl Complexes As Potential Anti-cancer Drugs
(Chemistry & Biochemistry, 2009-09-16)
Stereospecific binding of ruthenium metallointercalators with DNA is of particular interest because of the potential for improved targeting of specific sites in DNA. The present studies are focused on new metallointercalator, ...

(Social Work, 2009-09-16)
The researcher conducted an online survey through social networking sites to identify variables that influenced marital satisfaction among Operation Iraq Freedom (OIF) and Operation Enduring Freedom (OEF) veterans. ...
A Multi-functional Essay Prompt For State Mandated Assessments
(English, 2009-09-16)
A State-mandated assessment of high school English composition skills can be a trying experience for sophomore basic writers. Because students must construct a text-supported argument around the State's choice of theme, ...
Electron Emission From Surfaces Resulting From Low Energy Positron Bombardment
(Physics, 2009-09-16)
Measurements of the secondary electron energy spectra resulting from very low energy positron bombardment of a polycrystalline Au and Cu (100) surfaces are presented that provide evidence for a single step transition from ...
Thermal Analysis Of Pulse Detonation Engines
(Aerospace Engineering, 2009-09-16)
The pulse detonation engine (PDE) is a compact system that can be modeled thermodynamically by the Humphrey cycle and is capable of high efficiency. The rapid heat release for stochiometric fuel/oxidizer ratios results in ...
A Process For Ice Detector Placement Using 3-D Eulerian Droplet Impingement Analysis
(Aerospace Engineering, 2009-09-16)
Ice detectors invoke an aircraft's ice protection systems, which reduce the risks of flight into known icing conditions. A process has been developed to place ice detectors on aircraft using high fidelity computational ...
Simulations Of High-latitude Ionosphere-magnetosphere region plasma density structures and the Alfvén waves effects
(Physics, 2009-09-16)
O+ density structures in the polar cap ionosphere-magnetosphere region near 6000 km altitude have been observed with numerous spacecraft, with O+ densities ranging from above 10 cm-3 to lower than 0.01 cm-3. Regions with ...
On The Design Of A Biodegradable POC-HA Polymeric Cardiovascular Stent
(Mechanical Engineering, 2009-09-16)
The current state of the art in coronary stent technology is mainly populated by metallic stents usually coated with certain drugs to increase biocompatibility, even though experimental biodegradable stents have appeared ...
