Airborne sampling of particles emitted to the atmosphere from Kraft paper mill processes and their characterization by electron microscopy

Creator:: Augustine, Frank Edward
Abstract:: A high volume sampling system, employing Nuclepore filters and designed for sampling particulate in the plumes from industrial sources using a light aircraft, is described. The effluent of kraft paper mills was sampled using this system and then analyzed by electron microscopy. Size distributions of particles were obtained at several...

Evaluation of total hip arthroplasty research in the US and Europe

Creator:: Simmons, Marcy J.
Abstract:: Background: Hip replacements are considered routine operations which improve the quality of life in patients by reducing pain and restoring function. There are many variations in prostheses with varying benefits and disadvantages. Methods: Literature from the United States and Europe was collected on total hip replacements between 2001 and the...

Comparison of the Accuracy and Applicability of Forebody Wake Effect Models for Parachute System Design

Creator:: Kemling, Gabriel H. and Blunck, David L.
Abstract:: The forebody wake effect (FWE) is important to consider when designing parachute systems because it can affect parachute performance. Parachutes work by altering the aerodynamic properties of an attached forebody to control a descent. The FWE can reduce parachute drag, causing the system to descend faster than desired. This drag...

Feasibility of utilizing an integrating nephelometer to measure visibility

Creator:: Nelson, William George
Abstract:: An integrating nephelometer was set up at the Eugene Airport which is located five miles north of Eugene, Oregon, on Highway 99 West. Continuous atmospheric scattering coefficient readings were obtained from July 1, 1969, to August 28, 1969. These data are converted to meteorological range through the use of the...

Partial recirculation of diesel engine exhaust for the reduction of oxides of nitrogen

Creator:: Addicott, Donald James
Abstract:: Oxides of nitrogen are a concern as effluents to atmospheres because they participate in photochemical reactions which produce smog, because they attenuate sunlight which gives the atmosphere a reddish brown cast, and because of their toxic properties and the health hazards associated with the photochemical products they produce. Oxides of...

A portable dual-range fuel flowmeter for automotive research

Creator:: Hodgkins, Chester
Abstract:: This describes the development of a new fuel flowmeter. Among the desired features were an accuracy of ±2%, a linear response to fuel flow rate, a means of increasing the sensitivity at the low end of the meter scale and portability so that it would be equally useful in the...

Innovative Rear Wing Design Research for Formula SAE

Creator:: Lukacovic, Kyle S.
Abstract:: The goal of this project is to research an innovative rear wing design for Formula SAE and determine if the concept could be beneficial for automotive racing purposes. The research consists of three steps. First, sensitivity analyses using computational fluid dynamics (CFD) simulation were performed on multiple configurations. Next an...

Computational Modeling of Smoldering Combustion in Wildland Fuels

Creator:: Jayasuriya, Waduge Jayani A.
Abstract:: Smoldering combustion in wildland fires is a critical phenomenon that needs in-depth study because it can initiate with weaker ignition sources, can persist for long periods, is difficult to suppress, and can transit to flaming combustion. Cellulose, hemicellulose, and lignin are the major organic constituents within biomass, in varying proportions...
