Spectrophotometric evaluation of color changes of esthetic brackets stored in potentially staining solutions

The purpose of this study was to evaluate, in vitro, the chromatic behavior of esthetic brackets stored in potentially staining solutions. The sample were divided into four groups according to the commercial brand and stored in four different solutions (distilled water, cola soda, coffee and mouthrinse) at 37°C for 14 days. Possible color changes measured according to the CIE L*a*b* color system with a spectrophotometer at five intervals of time after storage. The statistical analysis was carried out using ANOVA to 1%, Tukey's tests and decomposition of interactions with a significance level of 5%.The color changes were dependent on the solution, storage time and the brand of brackets. The largest color changes were observed in the G3, followed by G2, G1/G4. The esthetic brackets do not present satisfactory and stable chromatic behavior.

From Token, to Pioneer, to Crusader: Survival Strategies for Faculty of Color in PWI's

As the only person of color in your workplace you may experience feelings of isolation and hopelessness. However, it is possible to survive this situation. To do so, you must go .through an empowering developmental process. You no longer have to be a Token. Learn how you can become a Pioneer and a Crusader for social justice.

Positively Impacting the Retention Rates and Performance for Students-of-Color

This session reports on a first-year program designed to assist students-of-color in adjusting to higher education. Session participants will have the opportunity to view the overall structure of the program, including training components, academic tracking methodology, assessment and technology, enhancement programs, and additional services that S.T.A.R.S. provides.

The Importance of Affirmative Action in the 21st Century: Building Transformational Alliances with Constituencies Across the Power Structure for Scholars, Students and Staff of Color at Predominantly European American Institutions.

The purpose of this session is to reject the notion that proactive Affirmative Action strategic plans are no longer needed at predominantly European American Institutions. Data reveal an inverse relationship between creating successful strategic plans for inclusion and negative reactions from the power structure.

The Shaping of a New Identity: Continuation of the Transformation Process of People of Color on White University College Campuses Into "White" People of Color

“Our study will show how the pyramidal structure as a permanent feature of every aspect of American society continues to function in the same manner at institutions of higher learning.”

"100 CHALLENGES FACING STUDENTS OF COLOR IN THE 21st CENTURY"

"It is particularly critical to assess the impact, given the empirical data available, on institutions in California, Texas, Florida and Washington which anti-affirmative action laws and court orders have been passed/handed down."

“FAILING TO FIT: STUDENT DEVELOPMENT THEORIES AND STUDENTS OF COLOR”

Theories proposed by Chickering, Astin, Helms, Gilligan, and Perry serve as a framework for under¬standing and explaining the development of college students.

Kinetics of color center formation in silica irradiated with swift heavy ions: Thresholding and formation efficiency

We have determined the cross-section σ for color center generation under single Br ion impacts on amorphous SiO2. The evolution of the cross-sections, σ(E) and σ(Se), show an initial flat stage that we associate to atomic collision mechanisms. Above a certain threshold value (Se > 2 keV/nm), roughly coinciding with that reported for the onset of macroscopic disorder (compaction), σ shows a marked increase due to electronic processes. In this regime, a energetic cost of around 7.5 keV is necessary to create a non bridging oxygen hole center-E′ (NBOHC/E′) pair, whatever the input energy. The data appear consistent with a non-radiative decay of self-trapped excitons.
