TL;DR: Spectra of some lecithin and phosphatidylserine dispersions varied with time, due to a slow reorganization of randomly oriented multilamellar regions into longer, more ordered systems, with a length of about 1 μm.

TL;DR: A fish dip net assembly is constructed of water permeable and non-permeable material and is designed to catch or permit manipulation of fish between containers or bodies of water while providing and maintaining a continuous water environment to prevent injury or trauma to the fish as discussed by the authors.
Abstract: A fish dip net assembly is constructed of water permeable and non-permeable material and is designed to catch or permit manipulation of fish between containers or bodies of water while providing and maintaining a continuous water environment to prevent injury or trauma to the fish The permeable portion of the dip net assembly is fabricated from woven mesh material, which permits the net to be used for capturing fish, while the non-permeable portion of the dip net assembly is fabricated from a water retaining material to provide and maintain a continuous water environment for the fish Various embodiments of the invention for providing specialized functions relating to fish handling are described

TL;DR: In this paper, Fatigue crack growth tests were conducted with 1 in. plate specimens of SA508-CL 2 steel in room temperature air, 550$sup 0$F air and in a high purity, water environment.
Abstract: Fatigue crack growth tests were conducted with 1 in. plate specimens of SA508-CL 2 steel in room temperature air, 550$sup 0$F air and in a 550$sup 0$F, high purity, water environment. Zero-tension load controlled tests were run at cyclic frequencies as low as 0.037 CPM. Results show that growth rates in the simulated Boiling Water Reactor (BWR) water environment are faster than growth rates observed in 550$sup 0$F air and these rates are faster than the room temperature rate. In the BWR water environment, lowering the cyclic frequency from 0.37 to 0.037 CPM caused only a slight increase in the fatigue crack growth rate. All growth rates measured in these tests were below the upper bound design curve presented in Section XI of the ASME Code. (auth)

TL;DR: In this article, the Coanda effect was used to control the attitude and direction of a body in a water environment, which has advantages over existing methods in manoeuvrability and in the reduction of drag.
Abstract: This work concerns the generation of force from a peripheral nozzle at the front of an aerodynamic shaped body by the utilisation of the Coanda effect. It is found that the manipulation of the jet (envelope) distribution over the body surface may be manipulated to control the attitude and direction of the body in a water environment. Tests indicate that such devices have advantages over existing methods in manoeuvrability and in the reduction of drag.
