This paper presents experimental study results of a direct injection engine fed with methanol steam reforming products and devised to work with a high-pressure thermochemical recuperation system. The influence of injection pressure and timing on heat release rate, fuel mass fraction burned, cycle-to-cycle variation, pollutant emissions, efficiency and exhaust gas energy available for methanol reforming...
This paper presents the results of an experimental study on performance and pollutant emissions of a direct-injection spark-ignition engine devised for joint operation with a high-pressure thermochemical recuperation system based on methanol steam reforming. A comparison with gasoline and ethanol decomposition is performed. Engine feeding with methanol steam reforming products shows an 18%–39% increase...
As part of a larger multi-method study, 15 Black women college students participated in focus group discussions on the body. Contrary to popular theories that propose that Black women are protected by a “Black Culture” that buffers them from negative effects of body representations—thereby leaving them with higher body esteem—the themes that emerged in the focus group discussions indicate that young...
The purpose of this study was to investigate Latina, Black, and White women's conceptions of beauty and perceptions of cultural standards of beauty, as well as whether or not the participants were engaging in similar social comparison processes, specifically, the denial of personal disadvantage. One hundred and fifty-seven college women participated: 48 Latinas, 52 Black women, 51 White women, and...
