'Forehead to forehead I meet thee, this third time, Moby Dick!' [Ahab (Melville, 1851)] Herman Melville's fictional portrayal of the sinking of the Pequod was inspired by instances in which large sperm whales sank whaling ships by ramming the ships with their heads. Observations of aggression in species of the four major clades of cetacean and the artiodactyl outgroup suggest that head-butting ...

Abstract Despite the decreases in temperature and permeability of oceanic plates with increasing age, hydrothermal circulation (HC) can be rejuvenated 130-Ma old Pacific plate vicinity Japan Trench, substantially affecting thermal structure remaining amount magnetization (RAM). To decipher roles HC RAM, vigor extent Trench should quantitatively evaluated. Here we numerically show that is outer-...

The aim of the study was to identify heterosomes in the semen of three Romanov rams – carriers of leukocyte chimerism (FISH technique) and to determine the proportions between spermatozoa with X and Y chromosomes. The choice of bovine probes for hybridization with ram heterosomes was dictated by genetic conservatism of bovine and ovine heterosomes. The ratio between spermatozoa with a yellow fl...

this study was conducted to evaluate the effect of egg yolk and cooling on ram coated spermatozoa. semen was collected from three ram by artificial vagina contacted with a tube containing tris- fructose-egg yolk 15%. samples were pooled, centrifuged by 700 g for 10 min and removed supernatant. then, samples were diluted by tris-glucose and centrifuged again to remove seminal plasma and egg yolk...

Human trophy heads from the Wari site of Conchopata (AD 600-1000) are examined to evaluate if recently deceased persons or old corpses were used to make trophy heads and determine if the modifications are standardized. Similarly styled trophy heads may suggest state oversight that ensured uniform modifications, while different styles may suggest that various factions or kin groups prepared them...

Machine translation (MT) systems do not currently achieve optimal quality translation on free text, whatever translation method they employ. Our hypothesis is that the quality of MT will improve if an MT environment uses output from a variety of MT systems working on the same text. In the latest version of the Pangloss MT project, we collect the results of three translation engines typically, s...
