OBJECTIVE Compare the accuracy and reliability of fetal heart rate identification from maternal abdominal fetal electrocardiogram signals (ECG) and Doppler ultrasound with a fetal scalp electrode. DESIGN Prospective open method equivalence study. SETTING Three urban teaching hospitals in the Northeast United States. SAMPLE 75 women with normal pregnancies in labor at >37 weeks of gestatio...
abstract nowadaysphotovoltaic solar cells (pvs) areacknowledged the fastest growing energy technology in the word, however, they only account for only fraction of current global renewable energy capacity. it isrecognized that this incomplete market penetration has been largely a result of the technology’sexcessive cost. so researchers are trying to find innovative, economic way with theaim of ...
during natural gas processing, water in natural gas may cause to hydrates formation in pipelines which may lead to serious damages to process equipments. given the problems raised by present of water in natural gas, glycol solvent uses to remove water.in contact of glycol with gas always an amount of btex and voc absorb along with water, which on glycol recovery process, these substances separa...
A 2D model of laser melting consisting heat transfer, hydrodynamic flow, surface tension, and a free motion was established. physical field simulation the process performed, effect steady magnetic parameters on internal flow temperature fields melt pool analyzed validated by experiments. The results show that can suppress rate, but slightly influences its field, with an increase in strength, ri...
Small ubiquitin-like modifier (SUMO) family proteins regulate target-protein functions by post-translational modification. However, a potent and selective inhibitor targeting the SUMO pathway has been lacking. Here we describe ML-792, a mechanism-based SUMO-activating enzyme (SAE) inhibitor with nanomolar potency in cellular assays. ML-792 selectively blocks SAE enzyme activity and total SUMOyl...
