Comparison study of dicyandiamide-cured epoxy bonded steel joints and polyamidoamine-cured epoxy bonded steel joints
No full textThere are instances where efficiency and safety may be compromised as a result of deteriorating fluid transport systems. Thus, it is worth evaluating other methods that can repair the damage for a temporary period without shutting down the operation. The objective was to evaluate the durability of an epoxy-bonded steel in aqueous environments that would represent such a repair. EPON® 828 was chosen as the epoxy resin, and dicyandiamide and polyamidoamine were two types of curing agents evaluated in this study. The epoxy-bonded steel joints were exposed in either distilled water or 3.4% NaCl solution for various times. The mechanical strength of the bonded joints was evaluated using a three-point flexure test. The interfacial shear strength of unaged samples ranged from 0.93 to 0.32 MPa. It was found that the interfacial shear strength decreased with aging time for both epoxy-bonded systems. Scanning electron microscopy (SEM), optical microscopy, and X-ray photoelectron spectroscopy (XPS) were used to determine the locus of failure of the bonded joints. It was concluded that failure occurred cohesively within the oxide layer if oxides were present on the substrate surface prior to the bonding procedure

Subordination or empowerment? African-American leadership and the struggle for urban political power
No full textWhy have Blacks attained political empowerment in some cities and in others remained subordinated or had their achievements rolled back? Why do some cities have many black leaders with multi-racial appeal while other cities have none? Subordination or Empowerment? answers these questions through detailed historical examinations of the Black struggle for political power in Chicago, Gary, Philadelphia, and AtlantaMixing quantitative and qualitative data, author Richard Keiser argues that electoral competition among White factions has created opportunities for Black leaders to win genuine political empowerment and avoid subordination. Black leaders gain legitimacy among Whites by casting decisive votes and among Blacks by achieving common goals of the Black community. When electoral competition among whites does not exist, Black votes lose their electoral leverage, leading to the rise of extra-electoral strategies. Keiser's dynamic theory of leadership formation explains the current appeal of Black separatism and messianism at the local and national levels and the consequent rise of leaders such as Louis Farrakhan, and offers a rejoinder to Cornel West's critique of Black leadership in Race Matter
Washington Works: Ross Rieder and Ottilie Markholt discuss the importance of labor history approximately 1980s (clip)
No full textRoss Rieder and Ottilie Markholt discuss that Northwest Labor History is a history of business and the labor movement. Ottilie feels that the working people and their unions have been forgotten in our history. Knowing your history gives you a sense of empowerment, for the individual and for the movement. The Northwest has a colorful history in terms of the labor movement, including the Everett Massacre, which involved the IWW or the Wobblies.Clip Title supplied by Cataloger. Host of Washington Works: Karen Keiser. Guests: Ross Rieder, the President of the Pacific Northwest Labor History Association and Ottilie Markholt, a labor union author and supporter and a member of the board of the Pacific Northwest Labor Association.

Compatibility of Pt-3008 with selected components of the selenide isotope generator system
No full textThe first in a new generation of radioisotopic thermoelectric generators being built by Teledyne Energy Systems and designated the Selenide Isotope Generator has thermoelectric materials that can be degraded by reaction with O/sub 2/, H/sub 2/O, CO, and other gases. Consequently, for at least the first ground demonstration system a protective xenon atmosphere will be maintained over the thermoelectrics. The high-temperature portion of the atmosphere-retaining structure will be fabricated from the alloy Pt-3008 (Pt--30 wt % Rh--8 wt % W), which was developed at Oak Ridge National Laboratory. For this application Pt-3008 must be compatible with the various insulations and thermoelectric materials. A study of the compatibility of Pt-3008 with these materials and showed that Pt-3008 was embrittled after exposure to some of the insulations that were not adequately outgassed and by one of the thermoelectric materials (Cu/sub 2/Se) in some of the isothermal tests. It is believed that Pt-3008 will be compatible with the Selenide Isotope Generator materials when they are well outgassed and under the temperature gradient conditions of the operating system
Washington Works: Ross Rieder and Ottilie Markholt discuss the Centrailia Massacre approximately 1980
No full textOttilie Markholt and Ross Rieder discuss the Centralia Massacre and Everett were desperate attempts of the IWW, otherwise known as the Wobblies, to establish a presence and the lumber industry was vehemently against the activities. But it’s not all that defines labor history. These events are symbols of trends that have existed in our society.Clip Title supplied by Cataloger.Clip Title supplied by Cataloger.

Washington Works: Ross Rieder and Ottilie Markholt discuss union history approximately 1980 (clip)
No full textOttilie Markholt and Ross Rieder discuss early unions,the Wagner Act, Seattle General Strike, Wobblies and the Free Speech fight. They also discuss the resurgence of labor and the “spirit of unionism” as a reason why people are interested in learning more about their history. Washington State Labor history is very representative of other fights throughout the country.Clip Title supplied by Cataloger. Clip Title supplied by Cataloger.

Multidimensional assessment of Attention-Deficit/Hyperactivity Disorder (ADHD)
No full textThe present study examined the clinical utility of direct measures of neuropsychological performance (Pediatric Attention Disorder Diagnostic Screener Target Tests of Executive Functioning, Wide Range Assessment of Memory and Learning-Second Edition, Trail Making Test-Part A/B) and indirect measures of behavioral functioning (Behavior Rating Inventory of Executive Function (BRIEF)-Parent and Teacher Form) in the identification of children at risk for Attention Deficit-Hyperactivity Disorder (ADHD). The sample consisted of 80 elementary-aged children (6-12 years old), 40 ADHD and 40 Non-ADHD subjects, referred to a large community private practice setting in the Southern United States. Two sample t-tests (with Bonferroni correction) and effect sizes (Cohen’s d) were computed to assess statistical and practical performance differences between ADHD and Non-ADHD groups. Youth in the ADHD group performed significantly worse on direct neuropsychological measures, yielding lower mean scale scores on all TTEFs, 3 of 4 WRAML-2 indices, and TMT-Part B than youth in the Non-ADHD group. Group differences were not found for the BRIEF Parent and Teacher Forms. Implications of findings for research and practice are presented.Psy.
