The paper presents a new concept of determining the resultant position UAV (Unmanned Aerial Vehicle) based on individual SBAS (Satellite-Based Augmentation System) determinations from all available EGNOS (European Geostationary Navigation Overlay Service) satellites for SPP (Single Point Positioning) code method. To achieve this, authors propose weighted mean model to integrate data. was invers...

The advent of dual frequency Satellite Based Augmentation Systems (SBAS) will allow the aviation community to address some of the shortcomings of the current SBAS Minimum Operational Performance Standards (MOPS), in particular of the Vertical Protection Level (VPL), and also to adapt it to threats for a dual frequency user. First, satellite faults will become the dominant source of error – beca...

The Terrain Observation with Progressive Scans (TOPS) acquisition mode of Sentinel-1A provides a wide coverage per acquisition and features a repeat cycle of 12 days, making this acquisition mode attractive for surface subsidence monitoring. A few studies have analyzed wide-coverage surface subsidence of Wuhan based on Sentinel-1A data. In this study, we investigated wide-area surface subsidenc...

Introduction While Nigeria accounts for only 2% of the world population, it regrettably shares 14% of global maternal death burden. Whether its reported increase in antenatal care utilization is accompanied by increased use of skilled birth attendants (SBAs) is not known. This study assessed trends in utilization of SBAs in Nigeria between 1990 and 2013 and identified its determinants. Method...

OBJECTIVE Delivery by a skilled birth attendant (SBA) serves as an indicator of progress towards reducing maternal mortality worldwide -- the fifth Millennium Development Goal. Though WHO tracks the proportion of women delivered by SBAs, we know little about their competence to manage common life-threatening obstetric complications. We assessed SBA competence in five high maternal mortality set...

OBJECTIVE To explore use-inequity in maternal health-care services in home-based skilled-birth-attendant (SBA) programme areas in Bangladesh. METHODS Data from a community survey, conducted from February to May 2006, were analysed to examine inequities in use of SBAs, caesarean sections for deliveries and postnatal care services according to key socioeconomic factors. FINDINGS Of 2164 deliv...

Ten patients received a 30-min infusion of amikacin (30 mg/kg) on day 1 and 15 mg/kg on day 2. Mean serum creatinine was 1.1 +/- 0.3 (standard deviation) mg/dl before and 1.0 +/- 0.3 mg/dl 3 days after the second infusion. Mean serum amikacin concentrations before, at the end of infusion, and 1, 6, 12, and 24 h after 30 and 15 mg/kg were 0, 157, 79, 31, 16, 5, 5, 85, 51, 19, 12, and 5 mg/liter,...

The publishable result is a means of producing activated carbons and especially, SBAs, that exhibit a relatively high attrition resistance and a low propensity towards leaching from feedstocks that would, conventionally, yield activated carbons that were deficient with respect to these two properties. This process was developed using sewage sludge, but it is should function with all carbonised ...
