Triaxial consolidated drained, unconfined compression, and CBR tests have been conducted in order to study the stress-strain, strength, and volume change characteristics of fine sand specimens reinforced by polymeric fibers made from carpet wastes. The variables are aspect ratio (length/width) and weight percentage of the fibers. The results indicate that the peak strength and total volume chan...

The pedestrian-level wind environment quality in street canyons formed by high-rise buildings and other low-level buildings could be affected by multiple factors, such as the height and geometry of the surrounding buildings, street width, wind direction, and wind speed. This study conducted wind tunnel experiments to determine the characteristics of the pedestrian-level wind environment in stre...

i ntroduction: due to the increase in le fort surgeries and its effect on nose widening, it seems necessary to use an alternative method without this effect. the present research examined the effect of alar release on interalar changes in le fort i osteotomy. m at erials and methods: the study population included patients admitted to bou-ali hospital in 2012-2013 undergoing le fort i osteotomy....

For cementitious composites and materials, the sealing of fractures can occur in water by the precipitation of calcium compounds. In this study, the sealing behavior in a macro-fractured high-strength and ultra-low-permeability concrete (HSULPC) specimen was investigated in simulated seawater using micro-focus X-ray computed tomography (CT). In particular, the influence of fracture width (0.10 ...

background: the aim of this study was to determine the pattern and amount of change exhibited in mandibular intercanine and intermolar width during treatment and assessing its stability1-3 years post-retention. materials and methods: the material consisted of 70 cases of which 20 cases were treated without extraction and 30 cases were treated with extraction, which were compared with 20 untreat...

" Many psychologists recognize that problems and solutions in their field need redefinition, but change has been slow or nonexistent. Indeed, little is known about how to transform the practice of a profession. This article's purpose is to stimulate discussion about what we want our fields to become andhow to go about realizing our visions. A professional fantasy, using school psychology as an ...

In this experiment effect of two full and half width sinusoidal inner tubes in triplex-tube heat exchanger with phase change material (PCM) was investigated. Length and diameter of the tubes have been chosen such that the area of each tube to be the same. Charging and discharging processes were carried out by inner tube, outer tube and both. Results indicated, PCM melting and solidification tim...
