[frames, clouds, ladder, and wavy canyons]

Description: The blue sky is filled with wispy clouds, a ladder reaches from the lower edge of the work to the top edge. Two frame shapes reach from the outer edges of the work to the center creating depth. Behind the frames shapes are green wavy canyons.

[artwork of screen printed silk and handmade paper]

Description: The horizontally arranged artwork depicts various grids floating and moving in space to create depth. In the background is a large semi-circular shape in a textured blue green color. There is also a wide strip of brown that begins in the far lower right corner and moves at four different angles until it reaches the left side of the picture.

[artwork made of handmade paper and screen printed cotton velveteen]

Description: The horizontally arranged artwork consists of textured paper in a blue-green that gradates to a pink color and moves from the foreground to the background in a curving motion. Angular brown lines are in the background and the middle ground consists of pink colors. Some white cloud like forms float through the picture plane and a gray stacked shape fills the left side of the picture.

[artwork made of handmade paper and screen printed cotton velveteen]

Description: The horizontally arranged artwork consists of silhouettes of mountains in the distance in various pale shades of gray. In the foreground are two curved shapes consisting of parallel lines of textured pink paper. Three lines geometric in shape move through the picture plane flattening while also creating more space.

[artwork made of handmade paper on silk]

Description: The horizontally arranged work consists of perspective lines receding into the distance. Halfway into the distance the receding lines are covered in blue soft textured handmade paper fibers. The floor of the space is checkerboard pattern and also recedes into distance. A brown ribbon type images also slither into the distance.

[silk screened cotton velveteen artwork]

Description: This screen printed cotton velveteen artwork depicts in a horizontal orientation two curved brown boardwalk type images. These boardwalks reach through the sky and enter into two rectangular frame shapes. Mountainous shapes line the bottom edge of the work.

A method for rapid selection of design characteristics of 1-, 1 1/2-, and 2-stage turbines with optimum annulus taper

Description: Report presenting a method for the rapid selection of a turbine design within specified aerodynamic limits. Tables are provided with the overall design parameters and velocity-diagram variables of each design. Detailed design information is also included for ranges of blade-speed parameter and exit radius ratio.

Proposal for a propeller side-force factor

Description: Report discusses a proposal for propeller manufacturers to consider the side-force factor with the activity factor as a fundamental parameter for all blade designs and for the side-force factor to be included in all reports of powered models in wind tunnels. The proposal includes a method for calculating the side-force factor and how it can be used in propeller development. It is shown to be a good index of the relative effectiveness per blade of a yawed propeller in developing side force.

Calculation of Centrally Loaded Thin-Walled Columns Above the Buckling Limit

Description: When thin-walled columns formed from flanged sheet, such as used in airplane construction, are subjected to axial load, their behavior at failure varies according to the slenderness ratio. On long columns the axis deflects laterally while the cross section form is maintained; buckling results. The respective breaking load in the elastic range is computed by Euler's formula and for the plastic range by the Engesser- Karman formula. Its magnitude is essentially dependent upon the length. On intermediate length columns, especially where open sections are concerned, the cross section is distorted while the cross section form is preserved; twisting failure results. The buckling load in twisting is calculated according to Wagner and Kappus. On short columns the straight walls of low-bending resistance that form the column are deflected at the same time that the cross section form changes - buckling occurs without immediate failure. Then the buckling load of the total section computable from the buckling loads of the section walls is not the ultimate load; quite often, especially on thin-walled sections, it lies considerably higher and is secured by tests. Both loads, the buckling and the ultimate load are only in a small measure dependent upon length. The present report is an attempt to theoretically investigate the behavior of such short, thin-walled columns above the buckling load with the conventional calculating methods.

A Ferrocene-Based Catecholamide Ligand: the Consequences of Ligand Swivel for Directed Supramolecular Self-Assembly

Description: A ferrocene-based biscatecholamide ligand was prepared and investigated for the formation of metal-ligand supramolecular assemblies with different metals. Reaction with Ge(IV) resulted in the formation of a variety of Ge{sub n}L{sub m} coordination complexes, including [Ge{sub 2}L{sub 3}]{sup 4-} and [Ge{sub 2}L{sub 2}({mu}-OMe){sub 2}]{sup 2-}. The ligand's ability to swivel about the ferrocenyl linker and adopt different conformations accounts for formation of many different Ge{sub n}L{sub m} species. This study demonstrates why conformational ligand rigidity is essential in the rational design and directed self-assembly of supramolecular complexes.

[parallel bars, shiny circle, and ribbon]

Description: The red horizontal fabric artwork includes several vertical parallel lines with a ribbon floating behind to create depth. Lines and textures reminiscent of moss hanging from tree branches fill the left and lower portions of the work.
