The Effects of Varying a T Group Design upon Self Concept

The purpose of this study was to examine what effects the varying of a T Group design would have upon self-concept and also to determine whether or not individuals who had participated in a T Group would report more positive self-concepts than persons who had not had such an experience

Letter from George W. Woodruff to [Theodore Roosevelt], 1907 Sep 18.

Copy)DOM DEPARTMENT OF THE INTERIOR, WASHINGTON.W. B. A.September 18, 1907.THE PRESIDENT:Tour letter of the 16th instant has been received, enclosing a communication from Mr. John Muir protesting against the projects for storage reservoirs for the San Francisco water-supply in the Yosemite National Park, and requesting a report thereon.In response thereto, I have the honor to state that a communication was received at this Department from Mr. Muir on the 12th instant on the same subject, and he was advised on the 14th that the matter would be presented to the Secretary on his return to the city about October 1st. He was further informed that, at a hearing on the application of the City of San Francisco for water from the Tuolumne River and a reservoir site in the Hetch Hetchy Valley, Yosemite National Park, held in San Francisco July 24, 1907, it was agreed by those in favor of, as well as by those opposed to the granting of the application, to submit briefs on the subject for the consideration of the Secretary. These briefs have now been received, and will be prepared for the consideration of the Secretary on his return to the city.Mr. Muir\u27s letter and accompanying enclosure are herewith returned.Very respectfully,(Signed)GEORGE W.

Microfluidic Channels in Polymethyl-Methacrylate by Optimizing Aluminum Adhesion

A study has been performed to determine the optimum surface treatment to adhere an aluminum hard mask to a polymethyl-methacrylate (PMMA) wafer substrate for the production of microfluidic channels. The initial process parameters of the PMMA reactive ion surface treatment included oxygen plasma, sulfur hexafluoride plasma and argon plasma designs of experiments. However, a soak in tetra methyl ammonium hydroxide (TMAH) proved to provide the most adhereable surface for an aluminum deposition. It is hypothesized that the TMAH soak allowed for the removal of the surface layer of the PMMA wafer substrate. The aluminum hard mask was deposited by evaporation after the wafers were surface treated with TMAH. Using contact photolithography, the aluminum was patterned and the PMMA wafer substrate was etched isotropically in propalene glycol mono methyl ether acetate (PGMEA) for the creation of microfluidic channels. Success of this project is based on the quality of the aluminum evaporated film and the transparency of the PMMA wafer substrates after the isotropic etch in PGMEA
