In comparison to language-based AOP approaches, aspectoriented frameworks have the inherent advantage of a better integration with the existing development process. In this paper, we discuss some of the less evident advantages of framework-based approaches for general-purpose AOP: ability to build programmatic abstractions, flexibility and dynamic nature, a better integration between aspects an...

Clouds reduce the degree of linear polarization (DOLP) of skylight relative to that of a clear sky. Even thin subvisual clouds in the "twilight zone" between clouds and aerosols produce a drop in skylight DOLP long before clouds become visible in the sky. In contrast, the angle of polarization (AOP) of light scattered by a cloud in a partly cloudy sky remains the same as in the clear sky for mo...

Photodegradation of the antibiotic sulphamethoxazole (SMX) in water using a medium-pressure UV lamp combined with H2O2 (UV/H2O2) was used to generate the advanced oxidation process (AOP). The photodegradation process was steadily improved with addition of H2O2 at relatively low to moderate concentrations (5 to 50 mg L(-1)). However, the addition of H2O2 to the photolysis process at higher conce...

BACKGROUND Maternal anemia, a common situation in developing countries, provokes impairment of nutrients/oxygen supply to the placenta-fetus unit that leads to Great obstetrical syndromes (GOS). In our setting, however, occurrence of GOS has been found also depending on variables existing prior to pregnancy such as diabetes in family, hypertension in family, previous macrosomia, stillbirth, SGA...

recombinant human erythropoietin (rh-epo) is known to accelerate erythropoiesis in preterm infants. the purpose of this study was to compare the effectiveness of early treatment with two doses of rh-epo (high vs. low dose) in the management of anemia of prematurity. twenty preterm infants with hematocrit (hct) < 30% when infant’s age was between 2 to 3 weeks after birth or hct <25% when infant’...

The transperineal ultrasound (TPU) value of the angle of progression (AOP) during fetal head engagement, at station 0, is a critical cut-off for current obstetrical practice, especially when intrapartum instrumental interventions are required. Still, controversial measurements were reported in previous high resolution imagistic studies. Our TPU and direct "gold-standard" magnetic resonance (MRI...

OBJECTIVE To compare the frequency and severity of apneic events in very low birth weight (VLBW) infants before and after blood transfusions using continuous electronic waveform analysis. STUDY DESIGN We continuously collected waveform, heart rate, and oxygen saturation data from patients in all 45 neonatal intensive care unit beds at the University of Virginia for 120 weeks. Central apneas w...

We describe how a gender specialist team managed the case of a disorder of sex development in a preterm infant where definitive diagnosis and gender assignment were delayed due to complications of prematurity, anemia, and severe intrauterine growth restriction.
