in this paper, the mechanical behavior of three-phase inhomogeneous materials is modeled using the meso-scale model with lattice beams for static and dynamic analyses. the timoshenko beam theory is applied instead of the classical euler-bernoulli beam theory and the mechanical properties of lattice beam connection are derived based on the continuum medium using the non-local continuum theory. t...

some of the important mechanical loads in the civil and military industries are variable speed and power and their efficiency. mechanical coupling of two different electric motors is suitable for these types of application. using this technique reduces energy consumption of submarine’s motion system and submarine range would be increased. but the use of this technique requires a complex control...

background & aims: endotracheal intubation is commonly performed in the intensive care unit. many international guidelines for difficult intubation management are available and the intensivists think that any endotracheal intubation in icu is potentially difficult with several complications. materials & methods: after obtaining ethical approval, this descriptive and analytical study was conduct...
