background: the pregnancy was a risk factor for excessive weight gain for women. however, there is no information about the prevalence of obesity and its relationship with a history of pregnancy in girls. therefore, the purpose of this study was to investigate differences in the prevalence of obesity in adolescent females with a history of pregnancy and fac­tors associated with it, in korea. me...

The minimal distortion attainable in recovering the waveform of a continuous-time Wiener process from an encoded version of its uniform samples is considered. We first introduce a combined sampling and source coding problem for the Wiener process under uniform sampling, and prove an associated source coding theorem that characterizes the minimal distortion from samples. We then derive a closed-...

the shear strength and shear energy per unit area, as well as the force and energy required for picking flowers, are important parameters in the design and development of harvesting mechanisms. in this study, shear strength and shear energy per unit area of saffron (crocus sativus l.) stems were determined at different bevel angles and shear velocities. the force and energy required for picking...
