In most biomedical research, investigators hypothesize about the relationships of various factors, collect data to test those relationships, and try to draw conclusions about those relationships from the data collected.

This work tests the psychometric features of the Wijma Delivery Expectancy/Experience Questionnaire (WDEQ), a self-report instrument that measures the fear of childbirth, in an Italian sample. To 522 Italian primiparous women attending antenatal classes, the following assessments were administered: Wijma Delivery Expectancy/Experience Questionnaire (Wijma, Wijma, & Zar, 1998), StateTrait Anxiet...

Abstract In this paper, the timer control and inverter of pumping system are modelled simulated. The effects evaporation, rainfall seepage considered to make model more practical. proposed VFD used motor pump, which saves a lot cost. MATLAB/SCIP optimization software was implement developed model. Simulation assess performance electrical switching system. Two scenarios were simulate model: firs...
