W. E. B. Du Bois's Basic American Negro Creed and the Associates in Negro Folk Education: A Case of Repressive Tolerance in the Censorship of Radical Black Discourse on Adult Education  

Science.gov (United States)

W. E. B. Du Bois, one of the brightest lights in African American history, wrote a sparkling critique of the American social and economic system originally planned as part of the Bronze Booklets series, edited and published by Alain Locke and the Associates in Negro Folk Education. The piece was never published and has, until now, been lost to the annals of adult education history. Using historical evidence, the authors examine Du Bois's Basic American Negro Creed and the circumstances that led to its exclusion from the series. It is argued that the Creed was far too radical for the liberal minded Carnegie Corporation and its leaders who were only interested in accommodating adult education for Blacks through the AAAE funded Bronze Booklets. The exclusion of the Creed represents an example of repressive tolerance by the AAAE.

Morphological characteristics and medium-term evolution of the beaches between Ceuta and Cabo Negro (Morocco)  

British Library Electronic Table of Contents (United Kingdom)

This work presents the results of a combined study on the beach morphology and the evolution at short- and medium-term of the littoral between Ceuta and Cabo Negro (Morocco). It is an interesting sector showing a great increase of human occupation and coastal structures. The monitoring program allowed for the reconstruction of the beach morphological behavior and the seasonal changes. The studied beaches presented reflective profiles recording little seasonality, with the most notable morphological changes being strictly related to storms. Surf Similarity and Surf Scaling parameters highlighted the existence of intermediate and reflective beach states, characterized by plunging breakers. Aerial photographs and a satellite image have been geo-referenced and elaborated with GIS tools to reco...

Satellite-based estimates of groundwater storage variations in large drainage basins with extensive floodplains  

British Library Electronic Table of Contents (United Kingdom)

This study presents monthly estimates of groundwater anomalies in a large river basin dominated by extensive floodplains, the Negro River Basin, based on the synergistic analysis using multisatellite observations and hydrological models. For the period 2003-2004, changes in water stored in the aquifer is isolated from the total water storage measured by GRACE by removing contributions of both the surface reservoir, derived from satellite imagery and radar altimetry, and the root zone reservoir simulated by WGHM and LaD hydrological models. The groundwater anomalies show a realistic spatial pattern compared with the hydrogeological map of the basin, and similar temporal variations to local in situ groundwater observations and altimetry-derived level height measurements. Results highlight th...

Potential impacts assessment of plug-in electric vehicles on the Portuguese energy market  

British Library Electronic Table of Contents (United Kingdom)

Electric vehicles (EVs) and plug-in hybrid electric vehicles (PHEVs), which obtain their fuel from the grid by charging a battery, are set to be introduced into the mass market and expected to contribute to oil consumption reduction. In this research, scenarios for 2020 EVs penetration and charging profiles are studied integrated with different hypotheses for electricity production mix. The impacts in load profiles, spot electricity prices and emissions are obtained for the Portuguese case study. Simulations for year 2020, in a scenario of low hydro production and high prices, resulted in energy costs for EVs recharge of 20cents/kWh, with 2 million EVs charging mainly at evening peak hours. On the other hand, in an off-peak recharge, a high hydro production and low wholesale prices'...

The use of WASP model for planning the Portuguese electrical generating system: overcoming some difficulties  

International Nuclear Information System (INIS)

The paper discusses the methodology used at Electricidade de Portugal (EDP) in planning its electric power system. In particular, it considers a description of the methodology used by EDP for a more accurate definition of the input data required to characterize hydroelectric plants and the evaluation of their impact on an optimal long-term expansion plan. In addition, the paper describes an analysis of the results of studies, both with WASP-II and WASP-III, with and without pumped storage plants, respectively. Finally, the paper details the use of VALOR AGUA, in conjunction with WASP, for a better simulation of the hydroelectric system and which also permits to solve other problems closely connected such as the calculation of marginal production costs.

Occupational exposure to benzene: a prevention program for employees and contractors; PPEOB - Programa de Prevencao a Exposicao Ocupacional ao Benzeno para Empregados Proprios e Contratados  

Energy Technology Data Exchange (ETDEWEB)

PETROBRAS/TRANSPETRO Pipelines and Terminals has 500 regular employees and 5.064 out sourced workers in its Southeast Division. The out sourced employees work through 125 contracts involving a wide range of activities such as maintenance, operational, pipeline launching , engineering, administrative and auxiliary services. Among these workers, 200 people are subjected to benzene occupational exposure, which might be present in the products we transport in our pipelines. Benzene is recognized as a carcinogen according to ACGIH and Brazilian Ministry of Labour regulation NR- 15. Exposure to benzene in an uncontrolled way, be it chronic or sharp, may affect the worker's health such as: hematological alterations, neoplasys, neurobehavior alterations. Our program PPEOB (acronym in Portuguese for benzene occupational exposure prevention program) involved the work force and fosters health by anticipation, recognition, evaluation and control of the situations that ...

Exergy-based method for analyzing the composition of the electricity cost generated in gas-fired combined cycle plants  

International Nuclear Information System (INIS)

The proposed method to analyze the composition of the cost of electricity is based on the energy conversion processes and the destruction of the exergy through the several thermodynamic processes that comprise a combined cycle power plant. The method uses thermoeconomics to evaluate and allocate the cost of exergy throughout the processes, considering costs related to inputs and investment in equipment. Although the concept may be applied to any combined cycle or cogeneration plant, this work develops only the mathematical modeling for three-pressure heat recovery steam generator (HRSG) configurations and total condensation of the produced steam. It is possible to study any nx1 plant configuration (n sets of gas turbine and HRSGs associated to one steam turbine generator and condenser) with the developed model, assuming that every train operates identically and in steady state. The presented model was conceived from a complex configuration of a real power plant, over which variations ...
