Here we present two experiments investigating the implicit orienting of attention over time by entrainment to an auditory rhythmic stimulus. In the first experiment, participants carried out a detection and discrimination tasks with auditory and visual targets while listening to an isochronous, auditory sequence, which acted as the entraining stimulus. For the second experiment, we used musical...

The use of marble wastes in concrete mixtures, causing air and water pollution, has been promoted the academic practical spheres construction industry. Although effects various forms (powder, fine, coarse mixed) this waste on compressive strength subject to a decent number studies literature, difficulties reaching specific conclusions effect each test parameter constitute major restraint for pr...

Air pollution control in the United States for five common pollutants--particulate matter, ground-level ozone, sulfur dioxide, nitrogen dioxide, and carbon monoxide--is based partly on the attainment of ambient air quality standards that represent a level of air pollution regarded as safe. Regulatory and health agencies often focus on whether standards for short periods are attained; the number...

The development of environmentally accepted methods of used tire disposal is one of the greatest challenges that waste management experts face today. Use of waste rubber particles as aggregate in self-compacting concrete is a suitable solution for the environmental hazards of waste tires being produced on a large scale. The aim of this work is to investigate the influence of the size of waste r...

A flatbed scanner is used to collect a digital image of a polished cross-section through a concrete pavement. Image processing software is used to classify each pixel in the image as either cement paste, aggregate, or air void. The distance to the nearest air void is calculated for each pixel classified as cement paste using an accumulated cost surface algorithm. The presence of aggregate is ac...

Recently, the demands on concretes with no fines aggregate has been increased as a results of industry revolution. Many researchers are trying to recycle and rubble. In addition, increase in noise surrounding environment result growing population cars generated an urgent need produce characterized by good sound insulation. No-fines is considered kind porous lightweights concretes, gained removi...
