embryonic crown rump length (CRL) and heart rate were measured ultrasonographically between 35 and 47 days from the mean day of a three-day mating period in baboons ( n = 18) and between 42 to 58 days from fertilization as calculated from the CRL measurements in human pregnancies ( n = ...
Significant correlations ( p > 0.01) were noted between ultrasonographic measurements and Carnegie stages of development in both humans and baboons. Only the gestational and the yolk sacs were significantly smaller in baboons than in humans ( p > 0.05). The findings that embryonic CRL, extra-...

The initial 60 days (8 weeks) of human embryonic development can be categorized into 23 Carnegie stages [7, 8]. The cell differentiation and morphogenesis at various developmental stages can be characterized by the formation of zygote, pronuclei, morula, blastocyst, free blastocyst and the attachi...

If life is “a cosmic imperative that emerges on any mineral- and water-rich world,” the authors say, “then these findings support the hypothesis that life on Earth?emerged rapidly, in concert with a vibrant, diverse Mineral Kingdom, in the earliest stages of planetary evolution.” ...

His love for jazz blossomed during his regular performances at the Blue Note Jazz Bar, where he immersed himself in the genre and learned from seasoned musicians. This period saw him sharing stages with luminaries like Teddy Edwards, The Average White Band, and Georgie F...

aEver since the relevance theory first proposed, it has undergone much development. The theory has developed in several stages. In the updated edition, Sperber and Wilson find that the maxim of relevance in Grice’s co-operative principle was not very explicitly developed in Grice’s analysis or...
