Abstract: A blade (300) for a rowing oar (100), comprises: a first lifting element (310a) having a first chord line (320a) at a first point along its span, the first chord line extending from a trailing edge (340a) to a leading edge (330a) of the first lifting element; a second lifting element (310b) having a second chord line (320b) at a second point along its span, the second chord line extending from a trailing edge (340b) to a leading edge (330b) of the second lifting element; and a slot (370a) through which water may flow when in use, the slot (370a) having a constant width across more than half of the slot's length. The constant width extends between the trailing edge of the second lifting element (340b) and the nearest point on the first lifting element. The first and the second chord lines (340a, 340b) are non-parallel so as to form a first angle (550b) therebetween.

Abstract: The wall thickness of lipid microtubules are controlled by selecting a methanol/water system and determining the required amount of a lipid to form the desired wall thickness. The lipid is dissolved in a small portion of the heated methanol and that clear solution is added to the remaining amount of the heated methanol/water system. By slowly cooling the solution, microtubules are formed which have the desired wall thickness. Preferred microtubules have a wall thickness of just 2 bilayers and they are robust so they can be further coated. They can be made with a large aspect ratio and with lengths of greater than 250 microns. The process permits production of microtubules in very high yields.

Abstract: A composition is provided having cylindrically shaped metal or metal-coated particles and a polymer latex dispersion. A coating is provided having cylindrically shaped metal or metal-coated particles and a polymer matrix formed from a latex dispersion. The particles form a continuous, conductive network. A method of electromagnetic shielding is provided having the steps of providing the above composition, applying the composition to a surface, and drying the applied composition.

Abstract: A phase-contrast x-ray computed tomography scanner, a monochromatic diffraction computed tomography scanner, a rotatable monochromatic diffraction computed tomography scanner, and a combination phase-contrast and monochromatic computed tomography scanner are provided. In addition, a method of identifying an unknown sample is provided.

Abstract: An apparatus and method for fabricating corrugated composite stiffeners provides a base tool having grooves formed in an outer surface and a roller having a rotating shaft and a removable, lobed, elastomeric member surrounding the shaft. The lobes of the elastomeric member form a radial array around the shaft and match the contours of the grooves in the base tool. A section of prepreg fabric is placed between the roller and the base tool, and the roller is rotated to sequentially engage the lobes with the grooves, the lobes pressing the fabric into the grooves, the fabric conforming to the contours of the grooves. Several layers of fabric are applied, then the elastomeric member is released from the shaft, laid out flat, and placed on the fabric on the base tool, the lobes locating in the grooves. The base tool, fabric, and elastomeric member are enclosed in a vacuum bag and heated to cure the fabric.

Abstract: A housing for at least partially housing a boat lift pulley of a boat lift includes a main wall having a substantially vertically disposed wall portion defining an inwardly opening generally concave chamber adapted to at least partially receive therein a boat lift pulley. The main wall includes vertical and horizontal planes disposed substantially normal to each other with the concave chamber being offset to one side of the vertical plane. First and second wall portions of the main wall located at opposite sides of the horizontal plane are adapted for selective removal whereby a gear driven shaft can project therethrough to adapt a housing for selective utilization in either of two positions of installation oriented 180.degree. relative to each other. A peripheral edge portion of the main wall preferably includes symmetrically located fasteners for securing the housing to a companion housing in each of the two positions of 180.degree. oriented installation.
