2. Motivation for Air-Launch: Past, Present, and Future

Author

Kelly, John W, Rogers, Charles E, Brierly, Gregory T, Martin, J Campbell, and Murphy, Marshall G

Subjects
Aeronautics (General)
Abstract

Air-launch is defined as two or more air-vehicles joined and working together, that eventually separate in flight, and that have a combined performance greater than the sum of the individual parts. The use of the air-launch concept has taken many forms across civil, commercial, and military contexts throughout the history of aviation. Air-launch techniques have been applied for entertainment, movement of materiel and personnel, efficient execution of aeronautical research, increasing aircraft range, and enabling flexible and efficient launch of space vehicles. For each air-launch application identified in the paper, the motivation for that application is discussed.

3. HOSPITALS FOR RURAL PEOPLE.

Author

Department of Agriculture, Washington, DC., MANNY, ELSIE S., and ROGERS, CHARLES E.

Abstract

MODERN ADVANCEMENTS IN MEDICAL SCIENCE HAVE PRECIPITATED THE NEED FOR ADEQUATE UP-TO-DATE HOSPITAL FACILITIES REASONABLY CLOSE TO ALL PEOPLE. RURAL COMMUNITIES HAVE UTILIZED FEDERAL AID, STATE AID, ASSISTANCE FROM FOUNDATIONS, CIVIC BONDS, AND VOLUNTEER CONTRIBUTIONS AND DRIVES TO ERECT AND EQUIP HOSPITALS. HOSPITAL CARE FOR RURAL PEOPLE USUALLY TAKES THE FORM OF GROUP INSURANCE THROUGH EMPLOYERS' OR FARMERS' ORGANIZATIONS. STEPS INDIVIDUALS CAN TAKE IF NEW HEALTH FACILITIES ARE NEEDED IN THEIR COMMUNITY INCLUDE--(1) INTEREST OTHERS, (2) DETERMINE NEEDS AND OBJECTIVES, (3) DEVELOP FINANCING PLANS, (4) ENLIST SUPPORT OF A SPONSORING GROUP, (5) GAIN HELP FROM PROFESSIONAL GROUPS, (6) INVESTIGATE HOSPITAL SERVICES PAYMENT PLANS, AND (7) DEVELOP EDUCATIONAL PROGRAMS TO PROMOTE HEALTH GOALS. THIS BOOKLET IS ALSO AVAILABLE FOR $0.15 FROM THE SUPERINTENDENT OF DOCUMENTS, GOVERNMENT PRINTING OFFICE, WASHINGTON, D.C. 20402. (SF)

10. Nanosecond Pulse Shaping with Fiber-Based Electro-Optical Modulators and a Double-Pass Tapered Amplifier

Abstract

We describe a system for generating frequency-chirped and amplitude-shaped pulses on time scales from sub-nanosecond to ten nanoseconds. The system starts with cw diode-laser light at 780 nm and utilizes fiber-based electro-optical phase and intensity modulators, driven by an arbitrary waveform generator, to generate the shaped pulses. These pulses are subsequently amplified to several hundred mW with a tapered amplifier in a delayed double-pass configuration. Frequency chirps up to 5 GHz in 2 ns and pulse widths as short as 0.15 ns have been realized.

34. Oxyethylene copolymers with chloromethyl and (alkylthio)methyl or (alkylsulfonyl)methyl side groups: Syntheses and <TOGGLE>T<INF>g</INF></TOGGLE>/composition relationships

Author

Lee, Jong-Chan, Litt, Morton H., and Rogers, Charles E.

Abstract

New classes of copolymers, poly[oxy(chloromethyl)ethylene]/poly[oxy-((alkylthio)methyl)ethylene] copolymers (CE-ATEs), poly[oxy((alkylthio)methyl)-ethylene]s (ATEs), poly[oxy(chloromethyl)ethylene]/poly[oxy((alkylsulfonyl)meth-yl)ethylene] copolymers (CE-ASEs), and poly[oxy((alkylsulfonyl)methyl)ethylene]s (ASEs) have been made for the first time. The thioether-containing polymers (CE-ATEs and ATEs) were synthesized by reacting poly[oxy(chloromethyl)ethylene] (CE, poly(epichlorohydrin)) with different amounts of sodium alkanethiolates. The sulfone-containing polymers (CE-ASEs and ASEs) were synthesized by oxidizing the CE-ATEs and ATEs using m-chloroperoxybenzoic acid. The Fox equation, a linear relationship, fit the Tg/composition data for most CE-ATEs. The Tg's of the CE-ASEs showed positive deviations from those calculated using the Fox equation. The Johnston equation, in which steric and/or polar interactions between dissimilar monomeric units are considered by using TgAB (the Tg of the AB or BA dyad), fit the Tg/composition data for all copolymers in this study. © 1998 John Wiley & Sons, Inc.
