Notizen: Summary A male newborn with prenatal cytomegalovirus infection was referred for cranial ultrasound. The cranial ultrasound demonstrated areas of increased echogenicity in the thalamic and gray nuclei resembling “a branched candlestick”. Doppler technique located the “branched candlestick” along the thalamostriate arteries. This image is particularly interesting because to our knowledge it has never before been described in congenital cytomegalovirus infection, but only in congenital rubella.

Notizen: Commercial high density polyethylene and polyamide-6 (PA) resins were melt blended in the Brabender Plasticorder twin-screw extruder. The blends containing zero to 30 wt percent of polyamide-6 were examined in dynamic and steady state shear at 150, 200, and 250°C. The Theological test results are discussed in terms of morphology of the samples as observed under scanning electron microscope. Microscopy of the extrudates has shown a temperature dependent movement of the polyamide in the capillary during the extrusion and that fibrillation of the PA phase in the extensional field occurred at all temperatures.
