Bacterial crack repair to concrete

This study has demonstrated the potential S. pasteurii and consequently MICP holds in improving the integrity of finish to concrete, without the use of chemical based sealants. This is part of an ongoing range of experimental work designed to find an effective way of using bacteria as a cementitious repair agent

Evaluation of low wing-loading fuel conservative, short-haul transports

Fuel conservation that could be attained with two technology advancements, Q fan propulsion system and active control technology (ACT) was studied. Aircraft incorporating each technology were sized for a Federal Aviation Regulation (FAR) field length of 914 meters (3,000 feet), 148 passengers, and a 926 kilometer (500 nautical mile) mission. The cruise Mach number was .70 at 10100 meter (33,000 foot) altitude. The improvement resulting from application of the Q fan propulsion system was computed relative to an optimized fuel conservative transport design. The performance improvements resulting from application of ACT technology were relative to the optimized Q fan propulsion system configuration

The Black Power Movement in Trinidad: An Exploration of Gender and Cultural Changes and the Development of a Feminist Consciousness

In February 1970 the Black Power movement in Trinidad exploded as thousands of young people took to the streets in massive demonstrations that rocked the island. The government responded by arresting activists and ultimately declaring a state of emergency. At the same time a group of young army officers, sympathetic to the Black Power movement, mutinied. Prime Minister Eric Williams and the People’s National Movement (PNM) government emerged from the uprising, severely shaken but still with a firm grip on powers. Women played an active role in the demonstrations and within the activist groups that were a part of the movement, but scholars and observers generally have failed to document their participation. This article explores the gender ideology of the Black Power movement, the participation of women, the effect of the fight against racism together with an increased level of race consciousness on gender awareness, and the cultural changes inspired by Black Power. It then analyses the emergence of a new and more radical phase of the women’s movement in Trinidad in the mid to late 1970s, which led to the beginnings of a feminist discourse. It follows that development by assessing the increased consumerism spawned by the oil boom and how it conflicted with Black Power ideology and affected the gender system. The final section will examine how women and men are portrayed in newspaper advertisements, women’s pages, letters, articles and other newspaper items

Young Adults with Visual Impairments and Driver\u27s Education: Journeys of Self-Efficacy, Identity, and Transition to Adulthood

A person’s ability to travel independently can determine whether he or she transitions successfully from one life stage to another. One critically important aspect of independent travel is coming to understand how vehicles move in the built environment. For youth without visual disabilities, this information is addressed in depth in driver’s education courses. In the case of adolescents with visual impairments, the acquisition of this information is more complex and raises a number of complicated questions. In this qualitative study, seven adults with visual impairments ages 18-27 and six of their family members are interviewed to determine the impact of driver’s education on future independent travel for individuals with low vision/blindness. Social theories from other disciplines are used to analyze data (HeavyRunner & Marshall, 2003; Kim, 2015; Tuck, 2009). Findings indicate the emergence of three key themes: people with visual impairments are perceived as incapable by people without disabilities, driving serves as a metaphor for ableism, and schools may be actively pushing students with visual impairments out of their home schools to attend residential schools for students with visual impairments to preserve resources for able-bodied students
