Isostatic equilibrium is commonly defined as the state achieved when there are no lateral gradients in hydrostatic pressure, and thus no lateral flow, at depth within the lower viscosity mantle that underlies a planetary body’s outer crust. In a constant-gravity Cartesian framework, this definition is equivalent to the requirement that columns of equal width contain equal masses. Here we show, ...
“Cold-formed steel (CFS) stud walls” are innovative alternative for construction of walls in buildings. The main frames of CFS walls consist of a group of vertical members called “studs” which are hold by fasteners within two horizontal members called “tracks” at the upper and lower ends. One of the conventional ways for designing and analyzing of CFS stud walls under blast loading is to employ...
Precise calculation of inlet pressure into sprinkler laterals is an important problem for proper distribution of uniformity. The adjusted average friction correction factor, FaAVG , provides the possibility of calculating the inlet pressure to mutli-outlet pressurized irrigation pipelines when the first outlet spacing from the pipe entrance is arbitrary. To investigate the effect of allowable h...
A series of physical modeling tests were conducted by means of a beam type geotechnical centrifuge machine in order to investigate the drainage impact on the slope failure mechanism under centrifugal acceleration. Meanwhile, the phenomenon of stress redistribution in undercut slopes and the formation of arching effect were studied. For this purpose, a poorly graded sandy soil (Silica sand No. 6...
Background & Aims: Control of the endotracheal tube cuff pressure and complications due to its incompatibility are one of the main challenges of care in most intensive care units. In this study, we investigated the effect of changing from supine to lateral decubitus position on the cuff pressure of intubated patients admitted to intensive care unit of Urmia Imam Hospital. Materials & Meth...
A series of centrifuge model tests were conducted to study the interaction between successively constructed adjacent foundation pits. The stress, deformation, and earth pressure on retaining structures settlement soil two pits during successive construction investigated by a comprehensive instrumentation program. To reveal effect sequence, both stress deformation compared. results showed that s...
BACKGROUND Hamstrings loading has previously been shown to increase tibiofemoral posterior translation and external rotation, which could contribute to patellofemoral malalignment and elevated patellofemoral pressures. The current study characterizes the influence of forces applied by the hamstrings on patellofemoral kinematics and the pressure applied to patellofemoral cartilage. METHODS Ten...
