An intensive experimental investigation was conducted to study the effect of vertical tail, single and twin (with different cant angles) on the flow field and the corresponding aerodynamic forces and moments of a model of a fighter A/C. Aerodynamic forces under different flight conditions and different vertical tail settings were measured in a supersonic wind tunnel. Furthermore, effects of ver...

background: daylight availability data are essential for designing effectively day lighted buildings. in respect to no available daylight availability data in iran, illuminance data on the south facing vertical surfaces were estimated using a proper method. methods: an illuminance measuring set was designed for measuring vertical illuminances for standard times over 15 days at one hour interval...

necrotizing soft tissue infections (nstis) are polymicrobial infections with high morbidity and mortality. we report a case of retroperitoneal nsti in an immunocompetent young male, with clinical symptoms and signs mimicking acute pancreatitis (pseudo-cullen’s and pseudo-grey-turner’s signs). the initiating lesion was a pustule which progressed and mimicked acute pancreatitis. ct scan showed fe...

In this paper the characteristics of unsteady three-dimensional incompressible flows with heat transfer are obtained along with artificial compressibility of Chorin. At first, compatibility equations and pseudo characteristics for three-dimensional flows are derived from five governing equations (continuity equation, Momentum equations in three directions, and energy equation) and then results ...

inclined retaining walls with slopes less than perpendicular are appropriate candidates in several engineering problems. yet, to the knowledge of authors, only a few analytical solution for calculation of active earth pressure on such walls, which will be usually smaller than the same pressure on vertical ones, has been presented neither in research papers nor in design codes. considering limit...

There is a substantial evidence that plyometric training significantly increases muscular strength and vertical jump. Due to the vigorous nature of this type of training, however, there is a risk of incurring musculoskeletal injuries. Therefore, conducting plyometric exercise programs in an aquatic environment might lead to significant improvements in vertical jump with possibly a lower risk of...

ABSTRACT The atmospheres of synchronously rotating exoplanets are intrinsically 3D, and fast vertical horizontal winds expected to mix the atmosphere, driving chemical composition out equilibrium. Due longer computation times associated with multidimensional forward models, mixing has only been investigated for a few case studies. In this paper, we aim generalize impact on chemistry exoplanet o...
