background: cesarean delivery is a surgery for deliver a baby. women with previous cesarean delivery (cd) must often choose between a vaginal delivery (vd) and repeat cd. our aim of this study was to investigate factors associated with preference for cd in neyshabur pregnant women with previous cd. methods: a cross‑sectional study was conducted on all pregnant women (who had previous caesarean ...

background: nowadays, there has been a growing trend of caesarean sections in iran. one reason would be the mother’s desire. increased maternal self‑efficacy can be an important step to reduce percentage of cesarean. this study aimed to determine the effectiveness of training‑based strategies to increase the self‑efficacy for choosing delivery method among pregnant women in shahrekord city. met...

In an energy-synchronized sensor network, each sensor node needs to synchronize its duty-cycle with its residual energy (or energy harvesting rate) to meet a predefined network lifetime requirement. A key research challenge of such energysynchronized sensor networks is how to collaboratively utilize the heterogeneous node duty-cycles for efficient and fair data delivery. In the proposed system,...

Background Multiple barriers exist to achieving energy and protein targets in the critically ill. Elke et al [1] used data from ICU’s worldwide which estimated average energy delivery of only 1057 kcals/day and protein delivery 49 g/d (0.7 g/ kg/d). Weijs et al [2] demonstrated that meeting energy and protein requirements is associated with decreased mortality. Local data from 2012 found an ave...

Data gathering is a fundamental task of Wireless Sensor Network (WSN). Recently, mobile sink has been exploited for data gathering in WSN to reduce and balance energy expenditure among sensors. To collect and transmit the data using energy efficient schemes in case of multiple mobile sinks is a hot research topic. In this project, a multiple mobile sinks energyefficient data collection (MSEDC) ...

background: the increasing number of cesarean section is a great concern in many countries. in iran cesarean section rate has been steadily rising from 35% in 2000 to 40% in 2005. preferences for cesarean are often associated with some factors. objective: to investigate factors associated with preference for cesarean delivery, with special emphasis on pregnant women’s preferences in first pregn...

Energy consumption and delay incurred in packet delivery are the two important metrics for measuring the performance of geographic routing protocols for Wireless Adhoc and Sensor Networks (WASN). A protocol capable of ensuring both lesser energy consumption and experiencing lesser delay in packet delivery is thus suitable for networks which are delay sensitive and energy hungry at the same time...

Mobile video services are becoming a dominant traffic category in emerging fourth generation (4G) cellular networks such as the 3GPP Long-Term Evolution (LTE) and LTE-Advanced (LTE-A). In particular, mobile video unicasting services based on 3GPP Dynamic Adaptive Streaming over HTTP (DASH) and multicasting/broadcasting services based on 3GPP evolved Multimedia Multicast/Broadcast Service (eMBMS...
