OBJECTIVE To compare the short-term efficacy of surfactant administration by laryngeal mask airway versus endotracheal tube. METHODS Preterm infants (28-35 weeks of gestational age), weighing 1kg or more, with respiratory distress syndrome, requiring nasal continuous positive airway pressure, with increased respiratory effort and/or fraction of inspired oxygen (FiO2)≥0.40 to maintain oxygen s...

Abstract This paper generally introduces the compliance verification method on airworthiness regulation CCAR 25.1443(c) of popular passenger oxygen system civil aircraft firstly, then technical interpretation <Minimum Mass Flow Supplemental Oxygen> is demonstrated and satisfying this in Top-Down design analyzed. For those based blood saturation which not directly fulfill requirement regul...

Solid Oxide Fuel Cells (SOFC) offer electrochemically generated sources of electricity using oxygen ion transport at elevated temperatures. Analysis of materials used in SOFC using electron microscopy provides insights of foreseeable chemical reactions that govern the performance of the fuel cell. Materials used in SOFC can be divided into four categories; anode, cathode, electrolyte and interc...

The oxygen requirement for chromophore formation potentially limits the use of green fluorescent protein as a reporter under hypoxic conditions. In the light of this, the applicability of a hypoxia-responsive enhanced green fluorescent protein (EGFP)-based system to the measurement of tumor hypoxia was tested in human HT 1080 fibrosarcoma cells stably transfected with a destabilized EGFP vector...

Requirement engineering is first phase of software development processes and it is most important phase for every software development model. In requirement engineering phase we can gather the requirements from user and use this requirement to software development and produce software product that satisfy the user needs. In other words, we have to see all requirements during the software's life...
