background: preeclampsia is the most prevalent complication of pregnancy and one ihird cause of death in pregnant women. developing of a screening test may help to early diagnosis. this study performed to compare diagnostic value of the roll over test and hematocrit level in early detection of preeclampsia.        methods: 660 pregnant women with gestational age of 24-28 weeks referred totamin ...

Web services are self-contained, self-describing, and loosely-coupled computational components designed to support machine-to-machine interaction by programmatic Web method calls, which allow structured data to be exchanged with remote resource. In the environment of service-oriented computing (Zhang et al, 2007), complex service-oriented systems are usually dynamically and automatically compos...

The foldable roll-over protective structure (FROPS) protects the operators against fatal injuries in tractor accidents. However, a rear-mounted FROPS is often folded down or removed. In present study, accessible zones and grasping areas were redesigned adapted to 5th, 50th, 95th European human anthropometric percentiles enhance its correct comfortable use. Then, rod was proposed as design solut...

The metal processing system usually consists of various components such like motors, work rolls, backup rolls, idle rolls, sensors, etc. Even a simple fault in a single component in the system may cause a serious damage on the final product. It is therefore necessary to diagnose the faults of the components to detect and prevent system failure. Especially, the defects in a work roll are critica...

Spatial orientation of the angular vestibuloocular reflex (aVOR) was studied in rhesus monkeys after complete and partial ablation of the nodulus and ventral uvula. Horizontal, vertical, and torsional components of slow phases of nystagmus were analyzed to determine the axes of eye rotation, the time constants (Tcs) of velocity storage, and its orientation vectors. The gravito-inertial accelera...

The roll forming industry has many difficulties in product development and process set-up. The design and development of rolls and processes re mainly based on trial-and-error and past experiences. Recent industrial trends demand products having high quality and tight tolerances. This equires more precise and cost-effective roll-forming processes than the ones employed in the traditional produc...
