This paper describes the collection of lion roar data at two different locations, an outdoor setting at Antelope Park in Zimbabwe and an indoor setting at Parken Zoo in Sweden. Preliminary analyses of spectrographic and waveform data are provided.

Recent ground-based observations of auroral radio waves have identified narrowband emissions near 2 and 3 times the lower ionospheric electron cyclotron frequency (fce) known as auroral roars. In this paper the propagation of these waves in the auroral ionosphere is investigated by means of a ray-tracing technique. We model one particular scenario in which a large-scale (tens of kilometers) hor...

It is well established that in humans, male voices are disproportionately lower pitched than female voices, and recent studies suggest that this dimorphism in fundamental frequency (F0) results from both intrasexual (male competition) and intersexual (female mate choice) selection for lower pitched voices in men. However, comparative investigations indicate that sexual dimorphism in F0 is not u...

In this Salur Qazan started describing himself with metaphorical saying that he was ‘cloud, smoke misty’. Beginning words about sky way harmony other declamations text.

Kick out the reticulons to close the envelope The nuclear envelope reforms when tube-forming reticulons are ejected from chromatin-associated ER tubules, say Anderson and Hetzer. The nuclear envelope was once thought to disintegrate into vesicles during mitosis, but growing evidence suggests it is absorbed into the endoplasmic reticulum. Recent in vitro experiments by these authors have shown t...
