This paper presents the development of a new compact three-axis compliant stage employing piezoelectric actuators and a new flexure structure. A proposed stage works out-of-plane (Z, θx, θy) direction. The stage consists of 4 amplification flexures mounted piezoelectric actuators. New structure of flexure reduces height and enhances dynamic performance of stage. To certify excellent performance...

conclusions: quality of peripartum care is moderate in lorestan province, therefore, continuous evaluation of quality of care by administrators and hospital staff is essential to improve this quality and will ultimately result in maternal and neonatal health improvement. results: the mean percentages of compatibility with desirable situation were 54%, 57% and 66% in first, second and third stag...

The roles of the various potential ecological and evolutionary causes of spatial population genetic structure (SPGS) cannot in general be inferred from the extant structure alone. However, a stage-specific analysis can provide clues as to the causes of SPGS. We conducted a stage-specific SPGS analysis of a mapped population of about 2000 Trillium grandiflorum (Liliaceae), a long-lived perennial...

the structural slenderness ration (height/ with) is one of the title that can be discussed in quake design of building. but unfortunately, in  iranian code isn’t mention this mater.in this article, bending and bracying structures system are chosen with slenderness ratio 2 upto 6. (11, 17, 23, 29, 35 stage).all of structure are analysed and designed in linear method, then analysed in unlinear me...

the date palm bunch fading disorder/disease is one of the greatest challenges faced by date palm growers. in the present study, the effect of appropriate orchard management on some qualitative and quantitative features of date palm bunch was studied. for this purpose, two orchards of cv ‘kabkab’ with a history of previous incidence were selected in two districts of bushehr province; tangestan a...
