[1] This work quantifies and explains the direct physical effects of slope angle on infiltration and runoff generation by extending the Green-Ampt equation onto sloping surfaces. A new extended solution using identical precipitation hydrographs was compared to the original formulation and then used to calculate the infiltration and runoff generation for different slope angles but for identical ...

spatial distribution of electric field amplitude has an essential role in laser-induced damagemulti-layer coating. a new method introduced in this paper to reduce the electric field intensityeffectively within the high index layers in multi-layer reflectors that are irradiated by high power lasers.the design is based on specific non-quarter wave pairs, assuming the number of layers is held cons...

The relationship between the equations used in the atomic pair distribution function (PDF) method and those commonly used in small-angle-scattering (SAS) analyses is explicitly shown. The origin of the sloping baseline, -4pirrho0, in PDFs of bulk materials is identified as originating from the SAS intensity that is neglected in PDF measurements. The nonlinear baseline in nanoparticles has the s...

This study determined effect of automobile seat backrest inclination on lattisimus dorsi muscle electromyographic (EMG) activity. Myoelectric activity was determined at two seat backrest angles (90 degrees and 100 degrees inclinations).  Twenty-one (21) participants were engaged in the study. Electromygraphic activity at 90 degrees inclination had slope value of -0.065 mV/minute while ...

BACKGROUND Dynamic alignment of "knee-in & toe-out" is a risk factor for anterior cruciate ligament injury and is possibly influenced by static knee alignment, range of tibial rotation and tibial plateau geometry. METHODS Twenty-eight healthy women were classified into valgus, neutral and varus groups based on static alignment of their knees. A 3-dimensional motion analysis was carried out fo...

Building of Dam from thousands of years BC was known, and the humans with use of them alwaystry to preserve and utilize surface water resources, but sedimentation problem always is the mostimportant factor in shortening the useful life of dams , and a lot of reservoirs were filled by sedimentsdue to this process and therefore most of dams have been abandoned. One of the most importantphenomena ...

Is there a correlation between increased posterior-inferior tibial slope angle and noncontact anterior cruciate ligament (ACL) injury? Does increasing the posterior-inferior tibial slope angle increase the risk of bilateral ACL injury? A computerized relational database (Access 2007; Microsoft Inc, Redmond, Washington) was used to conduct a retrospective review of patients undergoing bilateral ...
