Taking benefit of Radar resources in integrated RF sensor suites

2014 International Radar Conference, 2014

This paper is focused on the benefits provided by radar antennas in such architectures, due to their large size and power which are generally unmatched by other sensors. Examples of additional functions accessible through radar antennas are described, in the field of electronic warfare or communications. Results of technico-operational simulations of these functions are presented to illustrate expected gains in performance and reactivity. The conclusion shows the associated constraints in mission execution and shows how next generation radars will ultimately become multifunction RF sensors.

Es importante que las poblaciones asentadas en el área de estudio conozcan los peligros a los que están expuestos, así como el grado de vulnerabilidad física, social y económica que condiciona una situación de riesgo, de manera que les permita prepararse adecuadamente para incrementar su resiliencia, respondiendo con un comportamiento apropiado en la emergencia para salvar sus vidas.

Urinary excretion of epidermal growth factor and transforming growth factor-alpha in breast-fed and formula-fed infants

Acta Paediatrica, 1993

Urinary epidermal growth factor (EGF) and transforming growth factor-alpha (TGF-α) concentrations... more Urinary epidermal growth factor (EGF) and transforming growth factor-alpha (TGF-α) concentrations were determined by radioimmunoassay in a longitudinal study analyzing 348 24-h urine specimens of 32 infants (16 breast-fed, 16 formula-fed) during the first 16 weeks of life. EGF excretion showed a statistically significant increase from 6.0 ±2.5 to 14.1±4.9 μg/g creatinine (mean± 1 SD) during the investigation period. TGF-α levels were fairly constant throughout this period. Comparing breast-fed infants, with more than 100-fold higher ingestion of EGF and TGF-α, with formula-fed infants, no significant differences in urinary EGF and TGF-α excretion were observed. These results do not rule out a systemic effect of EGF and TGF-α after intestinal absorption in breast-fed infants. The results suggest, however, that urinary EGF and TGF-α originate mainly from sources other than intestinal absorption.
