BACKGROUND The electrical activity of the uterine muscle is representative of uterine contractility. Its characterization may be used to detect a potential risk of preterm delivery in women, even at an early gestational stage. METHODS We have investigated the effect of the recording electrode position on the spectral content of the signal by using a mathematical model of the women's abdomen. ...

BACKGROUND: Emerging research evidence suggests a potential benefit in being upright in the first stage of labour and a systematic review of trials suggests both benefits and harmful effects associated with being upright in the second stage of labour. Implementing evidence-based obstetric care in African countries with scarce resources is particularly challenging, and requires an understanding ...

BACKGROUND The objective of this work was to review the literature concerning the distribution of topical therapeutics to the sinuses versus nasal cavity regarding: surgical state, delivery device, head position, and nasal anatomy and to provide evidence-based recommendations. METHODS A systematic review was conducted using Medline, EMBASE, and Cochrane databases to perform a Medical Subject ...

To improve traffic safety and efficiency, it is vital to reliably send traffic-related messages to vehicles in the targeted region in vehicular ad hoc networks (VANETs). In this paper, we propose a novel scheme, relative position based message dissemination (RPB-MD), to reliably and efficiently disseminate messages to the vehicles in the zone-of-relevance. Firstly, the relative position based (...

Many different techniques have been used for xylem sap collection, but few direct comparisons of techniques have been conducted and few comparisons have been based on comprehensive analyses of xylem sap. Moreover, the suitability of extraction techniques for use on plants grown under water-stress conditions has not been addressed. Xylem sap was extracted from both well-watered and water-stresse...

In Wireless Sensor Networks, sensor nodes are controlled by either base station or without bases station. In our scheme, the sensor nodes are not depends on the base station. Once the sensor node sent a packet to the destination node, the residual energy is calculated through the multipath routing approach. In this research work, an Efficient Position based Packet Forwarding Protocol (EPPFP) to...

Intrafraction motion caused by breathing requires increased treatment margins for chest and abdominal radiotherapy and may lead to 'motion artefacts' in dose distributions during intensity modulated radiotherapy (IMRT). Technologies such as gated radiotherapy may significantly increase the treatment time, while breath-hold techniques may be poorly tolerated by pulmonarily compromised patients. ...

Mechanically ventilated critically ill patients treated in the intensive care unit (ICU) require enteral feedings to maintain adequate nutrition during critical illness. Delivery of adequate enteral nutrition is also critical to the recovery of critically ill patients. Enteral nutrition has been shown to decrease length of time on the ventilator, decrease length of stay and ICU and decrease mor...

D erivatives such as futures contracts on Treasury bonds (T-bonds) anci notes are tailorniade for hedging interest-rate risk, and in priticiple, computation of an optimal hedge ratio should be easy. The risk-minimizing number oi contracts is obtained by dividing the price value of a basis point {PVBP) ofthe underlying cash position (i.e., the change in dollar value resulting trom a I basis poin...

During pregnancy, the female reproductive organs and pelvic structures undergo dramatic changes in geometry, anatomical position, function to accommodate growing fetus prepare for delivery. these processes, various complications can occur significantly impacting baby mother's health are understudied from a biomechanical perspective. Biomedical engineers work cooperatively with clinicians biolog...
