abstract background: the incidence of pregnancy induced hypertension (pih) which is one of the three main causes of maternal-neonatal morbidity and mortality is 5-7%, and prediction of this disorder is very important in maternal and neonatal health. methods: the type of this study is analytical (comparative-prospective) and its purpose is to evaluate the isometric exercise test (let) and roll-o...

the cold roll bonding of al on aisi 304l stainless steel was carried out to fabricate the al/304l/al clad sheet composites. the maximum bond strength of 20 n/mm was acquired just by 38% reduction, for which the tearing of the aluminum sheet occurred during the peeling test. the microstructural evolution during subsequent postannealing heat treatment was systematically studied based on the impur...

OBJECTIVE To study the role of uterine artery notch on color Doppler ultrasound and roll over test in prediction of PIH. METHODS 100 women with high risk pregnancies were studied for presence or absence of uterine artery diastolic notch by Doppler ultrasound at 16-28 weeks. Same women were then subjected to roll over test at 28-32 weeks. RESULTS The primary outcome was that uterine diastoli...

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 ...

 ABSTRACT Background: The incidence of pregnancy induced hypertension (PIH) which is one of the three main causes of maternal-neonatal morbidity and mortality is 5-7%, and prediction of this disorder is very important in maternal and neonatal health. Methods: The type of this study is analytical (comparative-prospective) and its purpose is to evaluate the isometric exercise test (lET) and roll-...

The TomoTherapy Hi·Art System allows the application of rotational corrections as a part of the pretreatment image guidance process. This study outlines a custom method to perform an end-to-end evaluation of the TomoTherapy Hi·Art roll correction feature. A roll-sensitive plan was designed and delivered to a cylindrical solid water phantom to test the accuracy of roll corrections, as well as th...

An Al/Stainless Steel/Al lamellar composite was produced by roll bonding of the starting sheets at 400 °C. Afterward, the roll bonded sheet was cut in half and the accumulative roll bonding (ARB) process at room temperature was applied seven times. As a result, the central steel layer fractured and distributed in the Al matrix among different layers introduced by the repetition of roll bonding ...
