The article discusses a new model of the origins of choral singing in the context of human evolutionary history.Hominid interaction with predators is seen as a crucial force in the evolution of human morphology and behaviour.Group singing and dancing, with body painting and the use of masks, are perceived as critical elements of the strategy to det

We propose a dynamical imprinting scheme to create nodal lines of torus and lemniscate knots via a Raman process in a dilute spinor Bose-Einstein condensate.We calculate the desired parameters and the sophie allport bee curtains necessary spatial profiles of the Raman laser fields that couple a realistic multilevel atomic system, and demonstrate th

Ceramic materials based on complex oxides with both the perovskite structure (Ln2/3Nb2O6) and the structure borstlist sj?lvh?ftande of tetragonal tungsten bronze (Ba6-xLn8+2x/3Ti18O54) have been investigated over a wide frequency and temperature ranges.The results obtained for certain structures denote the presence of the temperature anomalies of d

Artesunate, a semisynthetic artemisinin derivative, is well-known and used as the first-line drug for treating malaria.Apart from treating malaria, artesunate has also been found to have biological u motion bowling ball activity against a variety of cancers and viruses.It also exhibits antidiabetic, anti-inflammatory, anti-atherosclerosis, immunosu
